Abstract

The present disclosure provides a clamp assembly for connecting a first component to a second plate-shaped component, the clamp assembly comprising a clamp seat and a clamp. The clamp seat includes a clamp connecting portion and a pair of side walls extending from the clamp connecting portion, and a mounting space is formed between the pair of side walls. The clamp is held within the mounting space, and the clamp has a support and a pair of elastic arms. The pair of elastic arms obliquely extend toward each other from opposite sides of the support of the clamp clamps the second plate-shaped component therebetween. The clamp connecting portion rotatably connects the clamp assembly to the first component. The clamp assembly of the present disclosure is rotatable relative to the first component.

Claims (35)

1 . A clamp assembly for connecting a first component to a second plate-shaped component, the clamp assembly comprising:

a clamp seat comprising a clamp connecting portion and a pair of side walls extending from the clamp connecting portion, a mounting space being formed between the pair of side walls; and

a clamp held within the mounting space, the clamp having a support and a pair of elastic arms, the pair of elastic arms obliquely extending toward each other from opposite sides of the support of the clamp and being configured to clamp the second plate-shaped component therebetween,

wherein the clamp connecting portion is configured to rotatably connect the clamp assembly to the first component,

wherein the support of the clamp further comprises:

a base plate; and

a pair of supporting portions extending from opposite sides of the base plate and arranged opposite each other,

wherein the pair of elastic arms are connected with distal ends of the pair of supporting portions, respectively, and the pair of elastic arms obliquely extend toward the base plate and toward each other.

2 . The clamp assembly of claim 1 , wherein the clamp connecting portion has a head, a neck, and a body, the neck being connected with the head and the body and being between the head and the body, the neck having a size smaller than sizes of the head and the body, the neck being cylindrical, and the neck being capable of being received by a receiving slot of the first component such that the clamp connecting portion is rotatably connected with the first component.

3 . The clamp assembly of claim 1 , wherein the pair of side walls each have a clamping portion at respective distal ends, and distal ends of the pair of elastic arms are capable of cooperating with the clamping portions so as to restrict movement of the clamp relative to the clamp seat in a direction away from the clamp connecting portion.

4 . The clamp assembly of claim 2 , wherein the clamp seat has a front side and a back side at two ends of the pair of side walls, respectively, the mounting space extending through the front side and the back side, and the clamp being capable of being assembled into the mounting space from the front side or the back side.

5 . The clamp assembly of claim 4 , wherein an outer contour of the head of the clamp connecting portion is circular, and an outer contour of the body is square.

6 . The clamp assembly of claim 1 , wherein the clamp is made of metal sheet stamping, with the pair of elastic arms having a hardness greater than that of a mounting part.

7 . A pipe fixing device assembly, comprising:

the clamp assembly of claim 1 ; and

a first component, the first component being a pipe seat having a pipe connecting portion, the pipe connecting portion being capable of cooperating with the clamp connecting portion so as to connect the clamp assembly with the pipe seat, wherein the clamp connecting portion is configured to be rotatable relative to the pipe seat.

8 . The pipe fixing device assembly of claim 7 , wherein;

the clamp connecting portion of the clamp assembly has a head, a neck, and a body, the neck having a size smaller than sizes of the head and the body, and the neck being cylindrical; and

the pipe connecting portion has a connecting plate having a receiving slot, the receiving slot having a size matching with that of the neck such that the neck is capable of entering the receiving slot and the connecting plate is capable of being clamped between the head and the body.

9 . The pipe fixing device assembly of claim 7 , wherein the pipe seat has a pipe mounting passage running through two sides of the pipe seat for fixing a pipe.

10 . A pipe fixing device assembly including a clamp assembly for connecting a first component to a second plate-shaped component, comprising:

the clamp assembly, including:

a clamp seat comprising a clamp connecting portion and a pair of side walls extending from the clamp connecting portion, a mounting space being formed between the pair of side walls; and

a clamp held within the mounting space, the clamp having a support and a pair of elastic arms, the pair of elastic arms obliquely extending toward each other from opposite sides of the support of the clamp and being configured to clamp the second plate-shaped component therebetween,

wherein the clamp connecting portion is configured to rotatably connect the clamp assembly to the first component; and

the first component, wherein the first component includes a pipe seat having a pipe connecting portion, the pipe connecting portion configured to cooperate with the clamp connecting portion so as to connect the clamp assembly with the pipe seat, wherein the clamp connecting portion is configured to be rotatable relative to the pipe seat.

11 . The pipe fixing device assembly of claim 10 , wherein the clamp connecting portion has a head, a neck, and a body, the neck being connected with the head and the body and being between the head and the body, the neck having a size smaller than sizes of the head and the body, the neck being cylindrical, and the neck being capable of being received by a receiving slot of the first component such that the clamp connecting portion is rotatably connected with the first component.

12 . The pipe fixing device assembly of claim 1 , wherein the pair of side walls each have a clamping portion at respective distal ends, and distal ends of the pair of elastic arms are capable of cooperating with the clamping portions so as to restrict movement of the clamp relative to the clamp seat in a direction away from the clamp connecting portion.

13 . The pipe fixing device assembly of claim 11 , wherein the clamp seat has a front side and a back side at two ends of the pair of side walls, respectively, the mounting space extending through the front side and the back side, and the clamp being capable of being assembled into the mounting space from the front side or the back side.

14 . The pipe fixing device assembly of claim 13 , wherein an outer contour of the head of the clamp connecting portion is circular, and an outer contour of the body is square.

15 . The pipe fixing device assembly of claim 10 , wherein the clamp is made of metal sheet stamping, with the pair of elastic arms having a hardness greater than that of a mounting part.

16 . The pipe fixing device assembly of claim 10 , wherein:

the clamp connecting portion of the clamp assembly has a head, a neck, and a body, the neck having a size smaller than sizes of the head and the body, and the neck being cylindrical; and

the pipe connecting portion has a connecting plate having a receiving slot, the receiving slot having a size matching with that of the neck such that the neck is capable of entering the receiving slot and the connecting plate is capable of being clamped between the head and the body.

17 . The pipe fixing device assembly of claim 10 , wherein the pipe seat has a pipe mounting passage running through two sides of the pipe seat for fixing a pipe.
