Description

Technical Field

[0001] The utility model relates to the technical field of metal structure watch straps, in particular to a watch strap buckle structure capable of adjusting the length without tools. Background Art

[0002] Watch strap is a general term for the effective part of a watch that fixes the wrist. There are many kinds of watch strap materials, cowhide is the most common one, and crocodile leather is the most precious one. Stainless steel, titanium, ceramics and other materials are the most commonly used metal structure watch strap materials. Metal structure watch straps are composed of fixed non-detachable parts and detachable parts (detachable grains). Due to the different sizes of consumers' wrists, watch straps are produced according to the largest wrist size when watches leave the factory. Therefore, after purchasing a watch, most consumers have to remove a certain number of strap grains to adjust the length of the strap in order to wear the watch properly.

[0003] Some existing watches have structures that can disassemble and assemble the strap without tools to adjust the length of the strap; however, the existing strap (chain) disassembly and assembly structure has high production technology requirements and a complex structure, which leads to great difficulty in production and processing, high defect rate, and undoubtedly increases production costs; the existing strap still has certain limitations in the process of disassembling the strap to adjust the length of the strap, so a strap buckle structure that can adjust the length without tools is proposed to solve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a watch strap buckle structure that can adjust the length without tools, has the advantages of not using screws to limit, and is easy to disassemble and adjust, thus solving the problem of poor adjustment effect and bad experience when the strap is disassembled.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a watch strap buckle structure that can adjust the length without tools, comprising a steel strap (titanium strap, ceramic strap), the steel strap is composed of fixed strap particles and detachable strap particles, the detachable strap particles include a watch strap mounting block and a watch strap connecting block, an adjustment mechanism is provided inside the watch strap mounting block; the adjustment mechanism includes a slider slidably connected to a mounting groove at the bottom of the mounting block, a reset spring is installed inside the slider; a rotating shaft is clamped between the slider and the mounting block, and buckles and undercut structures are provided on both sides of the slider and the mounting groove to limit the position.

[0006] Furthermore, the installation block and the upper and lower connecting blocks are fixedly connected together by two (or three) steel needles with teeth at both ends to form a section of grain belt (or the installation block and the upper and lower connecting blocks are an integral grain belt produced by a mold).

[0007] Furthermore, a mounting groove is provided on the bottom outer wall of the strap mounting block, and the slider is installed in the groove from the bottom and can slide left and right in the mounting groove; the reset spring is installed in the spring hole on the left side of the slider.

[0008] Furthermore, a slot is provided between the sliding block and the mounting block, and the rotating shaft is clamped inside the slot and has a size that matches the slot.

[0009] Furthermore, both sides of the slider and both sides of the installation slot are provided with buckle and undercut structures to match each other.

[0010] Furthermore, the width of the slot between the slider and the strap mounting block is greater than the diameter of the rotating shaft.

[0011] Furthermore, the slide block is pushed to the left, and a gap appears below the slot and the width of the gap is greater than the diameter of the shaft, so the shaft can be taken out downwards and a section of the belt can be removed.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The invention discloses a watch strap buckle structure that can adjust the length without tools. Through the cooperation of a mounting block, a slider, a reset spring and a buckle structure, a watch strap composed of a plurality of steel straps and strap particles can be freely adjusted and disassembled without using screws. The watch strap length is adjusted, and the assembly and disassembly is convenient without any tools, so that the watch strap disassembly structure is simpler, the use is more convenient and the production cost is lower.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1-5 In this embodiment, a watchband buckle structure that can adjust the length without tools includes a watchband mounting block 1 and a watchband connecting block 2, wherein the mounting block 1 and the upper and lower connecting blocks 2 are fixedly connected together by two (or three) steel needles with teeth at both ends; an adjustment mechanism is arranged inside the watchband mounting block 1; the adjustment mechanism includes a mounting groove 8 at the bottom of the mounting block 1, and both sides of the mounting groove 8 at the bottom of the watchband mounting block 1 have undercut structures; a slider 3 is inside the mounting groove 8, a spring hole 4 is arranged on the left side of the slider 3, and a reset spring 5 is closely attached to the right end of the spring hole 4; buckle structures are arranged on both sides of the slider 3, which cooperate with the undercut structures on both sides of the mounting groove 8, so that the slider 3 can be slid and connected left and right in the mounting groove 8; a clamping groove 7 is arranged between the slider 3 and the watchband mounting block 1, and a rotating shaft 6 is clamped inside the clamping groove 7 and the size is adapted; when the slider 3 is pushed to the left, a gap appears below the clamping groove 7 and the gap width is greater than the diameter of the rotating shaft 6, and the rotating shaft can be taken out downward to remove a section of the belt.

[0023] In this embodiment, the strap mounting block 1 and the upper and lower strap connecting blocks 2 are fixedly connected together by two steel needles with teeth at both ends to form a strap particle (or the mounting block and the upper and lower connecting blocks are an integral strap particle pressed out of a mold).

[0024] The working principle of the above embodiment is:

[0025] The slider 3 is then pressed upward along the buckle into the undercuts on both sides of the mounting groove 8 at the bottom of the mounting block 1 to limit the slider 3. The slider 3 can only slide left and right in the mounting groove 8. The slider 3 is pushed open to the left, and the shaft 6 between the two connecting blocks 2 can be taken out from the gap below the slot 7 to remove a section of the belt. At the same time, the slide groove 3 is pushed open to the left, and the shaft 6 between the connecting blocks 2 can be inserted from the bottom to the top. The slider 3 is released. Under the action of the reset spring 5, the slider 3 can close the slot 7, so that the shaft 6 can be rotated and connected in the slot 7 to add a section of the belt.
