Description

Technical Field

[0001] The utility model relates to the technical field of watches, in particular to a hook for adjusting the length of a watchband and a watch. Background Art

[0002] The length of a watch strap is usually adjustable. A tongue is provided at the outer end of one section of the strap, and multiple sockets are provided on the other section of the strap. The tongues are inserted into different sockets to adjust the length of the strap. After long-term and frequent use, the sockets are easily deformed or even damaged. A new type of watch strap has emerged, with multiple transverse holes distributed along the length of the strap. A buckle is inserted into the transverse holes, and then the clamping rod on the buckle is buckled with the hook at the end of the strap. To adjust the length, it is only necessary to adjust the buckle to pass through different transverse holes. However, when the existing hook is buckled with the clamping rod, the clamping rod is simply buckled into the inner side of the bend of the hook. When the user wears it, the watch needs to move synchronously with the user's watch, so the clamping rod is easy to slip out of the inner side of the bend of the hook, causing the watch to fall and be damaged.

[0003] Therefore, the prior art needs to be improved. Utility Model Content

A blocking mechanism 3 is provided on the hook plate 1. When the clip 5 and the hook form a buckle connection, the blocking mechanism 3 will block the clip 5 to prevent the clip 5 from sliding out of the bent part of the hook 11 as much as possible, causing the clip 5 to be separated from the hook, so that the clip 5 and the hook are not easily separated, and thus the watch can be prevented from falling and being damaged due to the separation of the clip 5 and the hook.

[0025] A mounting block 2 is provided on the hook plate 1. The mounting block 2 is integrally provided on the hook plate 1, and the mounting block 2 and the hook 11 are provided on the same side of the hook plate 1, and the mounting block 2 is provided on the side of the hook plate 1 away from the hook 11. The mounting block 2 is used for the installation of the blocking mechanism 3, so that when the hook buckle is engaged with the card rod 5, the side of the hook plate 1 away from the mounting block 2 is flat to enhance the experience, and at the same time, the space occupied by the hook buckle when the card rod 5 is engaged can be reduced; an opening 13 is formed at the side of the mounting block 2 away from the hook plate 1 and the end of the hook 11 away from the hook plate 1, and the opening 13 is used for the card rod 5 to slide in, and at the same time, the mounting block The side surface close to the hook 11 is arranged in an inclined state, so that the cross-sectional area of ​​the side of the mounting block 2 away from the hook plate 1 is smaller than the cross-sectional area of ​​the side close to the hook plate 1. The inclined surface is arranged to facilitate the sliding in and out of the round rod part of the clamping rod 5. At this time, a clamping channel 12 is formed between the hook plate 1, the hook 11 and the mounting block 2. The clamping channel 12 is composed of an inclined part and a horizontal part. The width of the clamping channel 12 is the same as or slightly larger than the diameter of the round rod part of the clamping rod 5. The opening 13 formed by the side surface of the mounting block 2 away from the hook plate 1 and the end of the hook 11 away from the hook plate 1 is the opening 13 of the clamping channel 12.

[0026] A through slot 21 for mounting one end of a watch strap is provided on a side of the mounting block 2 away from the hook 11, and the watch strap will be inserted into the through slot 21 and connected by a hexagonal screw, and a mounting slot 22 is provided at the bottom of the through slot 21, the bottom of the mounting slot 22 extends in a direction away from the slot opening of the through slot 21, the cross-section of the mounting slot 22 is circular when viewed from the slot opening direction, two mounting slots 22 are provided, and the two mounting slots 22 are arranged at intervals; the blocking mechanism 3 includes a blocking ball 31 and an elastic member 32, the blocking ball 31 is made of ceramic material, two blocking balls 31 are provided, and the two blocking balls 31 are respectively arranged at the bottom of the two mounting slots 22, the bottom of the mounting slot 22 is connected to the inclined surface of the mounting block 2, and the connecting area between the bottom of the mounting slot 22 and the inclined surface of the mounting block 2 is smaller than the diameter of the blocking ball 31, so that one side of the blocking ball 31 can extend from the mounting block 2 to block the card rod 5, and the elastic member 32 is provided in the mounting slot When the locking nut 31 is in the locking position, the locking nut 33 is in the locking position, and the locking nut 33 is in the locking position.

[0027] At the same time, the blocking plate 4 is detachably connected to the bottom of the through groove 21. In this embodiment, the detachable connection of the blocking plate 4 is achieved by screws. Therefore, after long-term use, the elastic force of the blocking spring 321 will decay, so the blocking spring 321 needs to be replaced. At this time, the blocking plate 4 can be removed by screws to achieve the replacement of the spring or the blocking ball 31.

[0028] The implementation principle of a hook for adjusting the length of a watch strap in an embodiment of the present application is as follows: when wearing a watch, align the card rod 5 with the opening 13 of the card connection channel 12. During the sliding in process of the card rod 5, the card rod 5 will abut against the blocking ball 31 to retract the blocking ball 31, and the card rod 5 can smoothly slide into the inner side of the bend of the hook 11. When the card rod 5 is separated from the blocking ball 31, the blocking ball 31 will be reset under the action of the blocking spring 321. At this time, the blocking ball 31 will block the card rod 5 to avoid the separation of the buckle and the hook as much as possible. When the buckle and the hook need to be separated, it is only necessary to slide the card rod 5 out of the opening 13 of the card connection channel 12 with force. It is simple and convenient to wear and has strong stability.

[0029] At the same time, in this embodiment, in order to further improve the connection stability between the buckle and the hook, a rubber layer 6 is provided on the inner side of the bend of the hook 11. The rubber layer 6 is made of an elastic material, preferably fluororubber, which has better wear resistance. Two groups of rubber layers 6 are provided. The two groups of rubber layers 6 are respectively arranged at the two side edges of the hook 11, and the two groups of rubber layers 6 are embedded in the inner side of the bend of the hook 11 to make the inner side of the bend of the hook 11 smooth. When the hook is buckled with the buckle, the clamping rod 5 is at the inner side of the bend of the hook 11, and the rubber layer 6 will increase the friction between the clamping rod 5 and the clamping rod 5. Through the dual action of the blocking ball 31 and the rubber layer 6, the connection between the clamping rod 5 and the hook 11 is more stable, thereby improving the connection stability between the hook and the buckle.

[0030] The utility model also provides a watch, referring to Figures 1 to 5 , including a dial, a watch strap connected to the dial, and one end of the watch strap is provided with the above-mentioned hook. The watch of this embodiment also has the above-mentioned beneficial effects, which will not be repeated here one by one.

[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
