Abstract

Claims (16)

1. A connection lock for connection with a watch bracelet, the connection lock comprising a body portion, the body portion comprising:

a receiving cavity is enclosed by a peripheral border of the body portion to receive a spare length of flexible tube or cable; the peripheral border of the body portion having a first side border, a second side border, a third side border, and a fourth side border connected in sequence; the first side border for connection with a bracelet strap, the bracelet strap has a receiving groove, the first side border includin a notch capable of aligning and communication with the receiving groove in the bracelet strap, so as to enable the flexible tube or the cable in the receiving cavity to pass into the receiving groove of the bracelet strap via the notch in the first side border;

at least two sliding connection portions respectively arranged at lower edges of the second side border and the fourth side border; the second side border and the fourth side border are arranged orthogonally to the first side border; the third side border oppositely located to the first side border and orthogonal to the second side border and the fourth side border; and

a connection opening arranged, adjacent to the notch, on the second side border of the body portion perpendicular to the sliding connection portions, wherein when an external fitting is connected to the flexible tube or the cable by sliding it onto the connection lock via the sliding connection portion of the connection lock and a sliding portion of the external fitting, a connection portion of the external fitting is slidable in from the connection opening such that the connection portion is connected to the flexible tube or the cable in the receiving cavity.

2. The connection lock of claim 1 , wherein a bottom of the connection opening is provided with a stopper having a first end close to the notch, a second end close to the connection opening, and a semicircular arc-shaped third end extending to a side opposite to the notch, so as to enable the flexible tube or the cable to be flexed into a U-shape to a minimum extent in the receiving cavity.

3. The connection lock of claim 2 , wherein the stopper is magnetic.

4. The connection lock of claim 1 , wherein the sliding connection portion is a sliding groove, and the sliding portion is a sliding rail; or the sliding connection portion is a sliding rail, and the sliding portion is a sliding groove; or the sliding connection portion and the sliding portion are linear sliding connection structures having interlocking shapes.

5. The connection lock of claim 1 , further comprising a lock brake for covering the body portion, wherein a first end of the lock brake is pivotally connected to a first end of the body portion, the first end of the body portion is configured for connection with the bracelet strap of the watch bracelet, and two side borders of the lock brake perpendicular to the sliding connection portions are provided with stop plates extending downwardly perpendicular to a cover surface of the lock brake; and when the lock brake covers a top of the receiving cavity of the body portion, the stop plates cover two ends of the two sliding connection portions.

6. The connection lock of claim 5 , wherein when the lock brake covers the top of the receiving cavity of the body portion, the stop plates further cover the connection opening.

7. The connection lock of claim 5 , further comprising a frame portion provided with a peripheral borders, wherein a first end of the frame portion is pivotally connected to a second end of the lock brake; and after the lock brake covers the top of the receiving cavity of the body portion, the frame portion is pivotable about the second end of the lock brake to enclose the lock brake and the body portion, and a second end of the frame portion is detachably connected to the first end of the body portion.

8. The connection lock of claim 7 , wherein a first pin portion and a second pin portion are respectively provided on two sides of the first end of the body portion, and a first hole corresponding to the first pin portion and a second hole corresponding to the second pin portion are respectively provided on two sides of the second end of the frame portion; and when the frame portion is pivoted about the second end of the lock brake to enclose the lock brake and the body portion, the first pin portion of the body portion is inserted into the first hole of the frame portion, and the second pin portion of the body portion is inserted into the second hole of the frame portion.

9. The connection lock of claim 8 , wherein a first inclined surface is provided in a plane where the first hole is located in a direction in which the frame portion is pivoted toward the body portion, the first inclined surface being connected to the plane and inclined downwardly relative to the plane; a second inclined surface is provided in a plane where the second hole is located in the direction in which the frame portion is pivoted toward the body portion, the second inclined surface being connected to the plane and inclined downwardly relative to the plane; and when the frame portion encloses the lock brake and the body portion, the first pin portion of the body portion is slid into the first hole of the frame portion from the first inclined surface, and the second pin portion of the body portion is slid into the second hole of the frame portion from the second inclined surface.

10. A watch bracelet, comprising at least one bracelet strap and the connection lock of any one of claims 1 to 9 , wherein the at least one bracelet strap is provided with a receiving groove, an end of the connection lock provided with a notch is connected to a first end of the at least one bracelet strap, and the notch of the connection lock is in alignment with the receiving groove of the bracelet strap.

11. The watch bracelet of claim 10 , further comprising a grooved bracelet fastener, a rear part of the grooved bracelet fastener being connected to a second end of the bracelet strap, and the grooved bracelet fastener being provided with a shaft groove which transversely penetrates a front part of the grooved bracelet fastener and which is recessed downwardly along an upper surface of the grooved bracelet fastener, and a sliding elastic cover arranged above the shaft groove, wherein the sliding elastic cover is configured to open or close the shaft groove, and the shaft groove is configured to accommodate a connection shaft of a watch body.

12. An external fitting, comprising: a body of the external fitting, a connection portion arranged on a surface of the body of the external fitting, and at least two sliding portions corresponding to the at least two sliding connection portions of the connection lock of any one of claims 1 to 9 , wherein

when the sliding portions of the external fitting are slid and connected to the sliding connection portions of the connection lock, the connection portion is slidable in from the connection opening of the connection lock.
