Abstract

The present application provides an adapter, a pipe assembly, a glue gun head and a glue applying device. The adapter is configured to connect a first pipe member to a second pipe member, wherein the adapter includes: a pipe joint, having a first accommodating part and a second accommodating part which are disposed at an interval in a first direction, the first accommodating part being configured to connect with the first pipe member, and the second accommodating part being configured to connect with the second pipe member; and a first sealing ring, disposed between the first accommodating part and the second accommodating part, so that the first pipe member and the second pipe member are able to abut against the first sealing ring from both sides of the first sealing ring in the first direction.

Claims (29)

1. An adapter, configured to connect a first pipe member to a second pipe member, wherein the adapter comprises:

a pipe joint, having a first accommodating part and a second accommodating part which are disposed at an interval in a first direction, wherein the first accommodating part is configured to connect with the first pipe member, and the second accommodating part is configured to connect with the second pipe member; and

a first sealing ring, disposed between the first accommodating part and the second accommodating part, so that the first pipe member and the second pipe member are able to abut against the first sealing ring from both sides of the first sealing ring in the first direction, the first sealing ring being in threaded connection with the pipe joint.

2. The adapter according to claim 1 , wherein

the first sealing ring comprises a first part and a second part, an outer diameter of the first part is smaller than an outer diameter of the second part, the pipe joint is provided with a stepped part, the stepped part comprises a first surface, a second surface and a third surface which are sequentially connected, a radial dimension of the third surface is greater than a radial dimension of the first surface, and the second part abuts against the second surface.

3. The adapter according to claim 2 , wherein

the pipe joint further comprises a first groove, the first groove is formed in an end part of the first sealing ring in the first direction, the adapter further comprises a second sealing ring, the second sealing ring is disposed in the first groove, and the second sealing ring is disposed on an outer side of the first sealing ring in a sleeving mode, and configured to abut against the first pipe member or the second pipe member in the first direction.

4. The adapter according to claim 3 , wherein

the second sealing ring comprises a base part and a protrusion part, the base part is disposed on an outer side of the first sealing ring in a sleeving mode, and configured to abut against the first pipe member or the second pipe member in the first direction, and the protrusion part protrudes from the base part in the first direction and has a thickness different from that of the base part, and is configured to abut against the first pipe member or the second pipe member from a peripheral side.

5. The adapter according to any one of claim 1 , wherein

the pipe joint is in threaded connection with the first pipe member and/or the second pipe member.

6. The adapter according to claim 1 , wherein

the periphery of the pipe joint is in a polygonal shape.

7. The adapter according to claim 1 , wherein

a peripheral surface of the pipe joint is provided with an anti-slip structure.

8. The adapter according to claim 1 , wherein

the pipe joint comprises a third sealing ring, a second groove is formed in at least one end of the pipe joint in the first direction, the third sealing ring is disposed in the second groove, and the third sealing ring is configured to be disposed on the periphery of the first pipe member or the second pipe member in a sleeving mode.

9. The adapter according to claim 1 , wherein

the material of the first sealing ring comprises polytetrafluoroethylene.

10. A pipe assembly, wherein the pipe assembly comprises:

the adapter according to claim 1 ;

a first pipe member, accommodated in the first accommodating part; and

a second pipe member, accommodated in the second accommodating part, the first pipe member and the second pipe member respectively abutting against the first sealing ring from both sides in the first direction.

11. The pipe assembly according to claim 10 , wherein

the first pipe member is a flat nozzle member, the flat nozzle member is of an integrated structure, and comprises a flat glue nozzle for spraying glue and a connecting pipe for connecting with the pipe joint and with at least one part engraved with external threads, the flat glue nozzle is located at an opposite side of the adapter of the connecting pipe, the connecting pipe is in threaded connection with the pipe joint, the second pipe member is a glue mixing pipe for inputting glue and with at least one part engraved with external threads, and the glue mixing pipe is in threaded connection with the pipe joint.

12. A glue gun head, configured to spray glue, wherein

the glue gun head is provided with the pipe assembly according to claim 11 .

13. An adapter, configured to connect a first pipe member to a second pipe member, wherein the adapter comprises: a pipe joint, having a first accommodating part and a second accommodating part which are disposed at an interval in a first direction, wherein the first accommodating part is configured to connect with the first pipe member, and the second accommodating part is configured to connect with the second pipe member; a first sealing ring, disposed between the first accommodating part and the second accommodating part, so that the first pipe member and the second pipe member are able to abut against the first sealing ring from both sides of the first sealing ring in the first direction; and a second sealing ring disposed on an outer side of the first sealing ring in a sleeving mode, and configured to abut against the first pipe member or the second pipe member in the first direction; wherein: the first sealing ring comprises a first part and a second part, an outer diameter of the first part is smaller than an outer diameter of the second part, the pipe joint is provided with a stepped part, the stepped part comprises a first surface, a second surface and a third surface which are sequentially connected, a radial dimension of the third surface is greater than a radial dimension of the first surface, and the second part abuts against the second surface; and the pipe joint further comprises a first groove, the first groove is formed in an end part of the first sealing ring in the first direction, the second sealing ring is disposed in the first groove.

14. An adapter, configured to connect a first pipe member to a second pipe member, wherein the adapter comprises: a pipe joint, having a first accommodating part and a second accommodating part which are disposed at an interval in a first direction, wherein the first accommodating part is configured to connect with the first pipe member, and the second accommodating part is configured to connect with the second pipe member; and a first sealing ring, disposed between the first accommodating part and the second accommodating part, so that the first pipe member and the second pipe member are able to abut against the first sealing ring from both sides of the first sealing ring in the first direction; wherein the pipe joint comprises a third sealing ring, a second groove is formed in at least one end of the pipe joint in the first direction, the third sealing ring is disposed in the groove, and the third sealing ring is configured to be disposed on the periphery of the first pipe member or the second pipe member in a sleeving mode.
