Description

Technical Field

[0001] The utility model relates to the technical field of watch parts, in particular to a strap adjusting buckle. Background Art

[0002] In order to dissipate heat well, existing watches are provided with a plurality of holes. These holes are arranged on the watch, making the watch strap present a fluffy and porous structure, so as to be able to buffer some collisions well and dissipate heat well.

[0003] At both ends of the strap of such watches, a watch buckle and an adjusting buckle (tail buckle) for receiving and folding the end of the strap will be fixedly arranged. However, the above-mentioned watch buckle and adjusting buckle are fixedly connected to the strap. When the watch strap needs to be folded and arranged, since the position of the adjusting buckle is fixed, if the user has a thick wrist, the overlapping part of the strap is less, so the length of the tail of the strap left is less. Therefore, it is very difficult for the adjusting buckle to function to fasten the strap.

[0004] And sometimes, the strap is sometimes loose, and there will be a gap left when the overlapping part of the strap is too long, making the strap bulky and not able to fit closely to the wrist. Therefore, a component that can fasten the strap according to the user's needs is required, and this component needs to be detachable. Summary of the Utility Model

[0020] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. When the number of an element is referred to as having "a plurality of", it can be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] The following provides a detailed description of this utility model in conjunction with the various embodiments shown in the drawings:

[0024] As Figures 1-3 shown, in this embodiment, a watchband adjustment buckle is provided, which includes a pull buckle post 1 and a pair of insertion cylinders 5 for inserting through the watchband. When it is necessary to adjust the position of this utility model on the watchband, the insertion cylinder 5 can be inserted into a specific position of the watchband, and the pull buckle post 1 is used for the insertion limit of the folded part of the watchband or the end part of the watchband.

[0025] On the same side of the pair of insertion cylinders 5 and the pull buckle post 1, there is a triangular fixing plate 2 fixedly connected together. This triangular fixing plate 2 mainly fixes the relative positions of the two insertion cylinders 5 and the pull buckle post 1 to remain unchanged. Inside the pull buckle post 1, a fixed base 10 is fixedly arranged. The fixed base 10 is fixedly connected to the triangular fixing plate 2. A pulling member is slidably arranged inside the pull buckle post 1. At the top of the fixed base 10, there is a limit ball 11 for the insertion limit of the pulling member; the function of the limit ball 11 is that when the cover plate 3 presses down the sleeve buckle, it can tighten the position of the pulling member, and the position of the cover plate 3 is limited by tightening the pulling member. One end of the pull buckle post 1 is rotatably connected to the cover plate 3, specifically referring to that the cover plate 3 can rotate relative to the pull buckle post 1. When this utility model needs to be separated from the watchband, the cover plate 3 is pulled up and rotated, and the watchband can be separated from the open end of the insertion cylinder 5, and the user can reselect a specific position on the watchband and re-insert it.

[0026] Further elaboration is as follows. The cover plate 3 is provided with a pair of pins 4, and the positioning groove is used for plugging with the insertion cylinder 5. The insertion cylinder 5 has a through structure. Therefore, the specific plugging process is that after the insertion cylinder 5 is inserted into a specific position of the watch band, the cover plate 3 is rotated into place so that the two pins 4 (mentioned below) can correspond to the positions of the two insertion cylinders 5. Then, the cover plate 3 is pressed, and the pins 4 on the cover plate 3 are inserted into the insertion cylinders 5 to complete the locking of the position of the cover plate 3, thereby determining the position of the buckle post 1. Since the main function of the buckle post 1 is the folding of the watch band.

[0027] In this embodiment, the pulling member includes a heightening post 9. A sleeve 8 is fixedly arranged at the end of the heightening post 9. A sliding rod 7 is coaxially and slidably arranged in the sleeve 8. A deformation fastener 12 is fixedly arranged at the bottom end of the sliding rod 7. The deformation fastener 12 is used for plugging with the limiting ball 11. When pulling out the cover plate 3, it is equivalent to pulling out the entire pulling member. Therefore, the deformation fastener 12 will be separated from the limiting ball 11 (mentioned below). When rotating the cover plate 3, the heightening post 9, the deformation fastener 12 and the sleeve 8 will all rotate accordingly. Specifically, a spring 6 is sleeved on the sliding rod 7. The two ends of the spring 6 respectively abut against the bottom of the sleeve 8 and the bottom of the deformation fastener 12. Since the deformation fastener 12 will be separated from the limiting ball 11 when pulling out the deformation fastener 12, but the deformation fastener 12 will still abut against the top of the limiting ball 11, so when pulling out, the integrally formed convex point inside the buckle post 1 will abut against the gap between the heightening post 9 and the sleeve 8 to prevent the heightening post 9 from being pulled out excessively and disengaging from the plugging of the buckle post 1. And at this time, since the deformation fastener 12 is pulled out, but the preset path inside the buckle post 1 remains unchanged, the sliding rod 7 will slide relative to the sleeve 8 to reduce the distance between the sleeve 8 and the deformation fastener 12. The spring 6 is contracted at this time.

[0028] In this embodiment, the bottom of the deformation fastener 12 has a frustum-shaped structure. A plurality of deformation grooves extending inward are annularly arranged at the bottom of the deformation fastener 12. The deformation grooves extend inward towards the center of the deformation fastener 12 and communicate with each other. The purpose of setting the deformation grooves is to leave a deformable space between the deformation fasteners 12. Specifically, the deformation fastener 12 is preferably made of a micro-elastic material. The purpose of opening the deformation grooves is to allow the bottom of the deformation fastener 12 to have a deformable space. When buckling onto the limiting ball 11, the deformation fastener 12 can be normally buckled onto the side wall of the limiting ball 11. When it needs to be pulled out, the middle and lower parts of the deformation fastener 12 will gradually expand outwards and deform until it is separated from the limiting ball 11 and then returns to its original shape again.

[0029] In this embodiment, the cover plate 3 is fixedly connected to the heightening post 9. The cover plate 3 is fixedly arranged at the top of the heightening post 9. The heightening post 9 is rotatably connected to the buckle post 1.

[0030] In this embodiment, in order to ensure that the sleeve 8 can slide on the sliding rod 7 while preventing the sleeve 8 from disengaging from the sliding rod 7, a channel is provided in the middle of the sleeve 8, and the sliding rod 7 is slidably disposed in the sleeve 8 through the channel. A limiting step protruding inward is provided at the bottom of the channel for limiting and abutting against the top of the sliding rod 7, and a disc protruding outwardly to the peripheral side is provided at the top of the sliding rod 7. In this way, no matter how the sleeve 8 is pulled outwards, it will not disengage from the buckling of the sliding rod 7.

[0031] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. For those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
