[0002] The fixing structure for watch case assembly is a crucial component in watch manufacturing. It is responsible for firmly connecting key parts of the watch case such as the dial and the backplate, ensuring that the internal electronic components and parts of the watch are in a safe and stable working environment.

[0003] The existing technology has the following drawbacks: the assembly of common watches is done by bolts, but the assembly process requires tools, is time-consuming and inefficient. If the screws or threads are stripped, repair is difficult. If the threads are stripped, it is difficult to achieve a stable connection by tightening the screws as usual. It is often necessary to re-process the watch body parts, such as enlarging the holes and tapping, which undoubtedly increases the maintenance cost and time cost, and may also damage the original appearance of the watch body. Therefore, a fixing structure for watch body assembly is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fixing structure for assembling watch bodies, aiming to solve the problem of the inability to quickly assemble and disassemble watch bodies in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fixing structure for assembling a watch body, including a watch face, a mounting block fixedly connected to the side wall of the watch face, a base plate detachably mounted to the bottom end of the watch face, a limiting mechanism provided on the inner wall of the base plate, a dial plate rotatably connected through the inner wall of the base plate, an annular groove opened on the inner wall of the watch face, a beveled opening opened at the bottom end of the base plate, and a sealing component provided on the inner wall of the watch face;

[0006] The limiting mechanism includes a rotating rod, the middle part of which is elastically connected to the base plate via a torsion spring, and a fixing block is fixedly connected to the outer wall of the rotating rod.

[0007] As a further description of the above technical solution:

[0008] The sealing assembly includes an airbag one, which is slidably connected to the inner wall of the dial. The top of the airbag one is elastically connected to the dial via a return spring, and the inner side wall of the dial is in contact with an airbag two.

[0009] As a further description of the above technical solution:

[0010] The top end of the airbag is fixedly connected to one end of the return spring, and the other end of the return spring is fixedly connected to the inner wall of the top of the dial.

[0011] As a further description of the above technical solution:

[0012] The bottom end of the airbag is attached to the top end of the base plate.

[0013] As a further description of the above technical solution:

[0014] The second airbag is fixedly connected to the top of the base plate.

[0015] As a further description of the above technical solution:

[0016] The middle part of the rotating rod is fixedly connected to one end of the torsion spring, and the other end of the torsion spring is fixedly connected to the inner wall of the base plate.

[0017] As a further description of the above technical solution:

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a watch body assembly fixing structure, including a watch face 1. A mounting block 2 is fixedly connected to the side wall of the watch face 1. The mounting block 2 has a slot to allow the watch strap to be connected to the mounting block 2. A base plate 3 is detachably installed at the bottom of the watch face 1. The base plate 3 is the bottom shell of the existing watch face 1. After installation, it can cover the electronic components and parts inside the watch face 1. A limit mechanism is provided on the inner wall of the base plate 3. A dial 7 is rotatably connected through the inner wall of the base plate 3. The dial 7 has friction texture to increase the friction with the operator's hand. An annular groove 9 is provided on the inner wall of the watch face 1. The annular groove 9 has an annular opening and a vertical opening. The annular opening allows the fixing block 6 to be locked in the inner wall of the annular opening, and the vertical opening allows the entire rotating rod 5 to move downward. An oblique opening 8 is provided at the bottom of the base plate 3. The oblique opening 8 is larger than the finger portion, allowing the finger portion to enter the oblique opening 8 to turn the dial 7. A sealing component is provided on the inner wall of the watch face 1.

[0034] The limiting mechanism includes a rotating rod 5, the middle of which is elastically connected to the base plate 3 via a torsion spring 4. An opening is provided in the middle of the rotating rod 5 to store the torsion spring 4, and a fixing block 6 is fixedly connected to the outer wall of the rotating rod 5.

[0035] Reference Figures 3-5The sealing assembly includes an airbag 11, which is slidably connected to the inner wall of the dial 1. The dial 1 has a slot that allows the airbag 11 to move vertically along the slot. The top of the airbag 11 is elastically connected to the dial 1 via a return spring 10. An airbag 2 12 is in contact with the inner side wall of the dial 1. The top of the airbag 11 is fixedly connected to one end of the return spring 10. When the airbag 11 moves upward, it compresses the return spring 10. When resetting, the return spring 10 uses its elasticity to reset the airbag 11. The other end of the return spring 10 is fixedly connected to the inner wall of the top of the dial 1. The bottom of the airbag 11 is in contact with the top of the base plate 3. The airbag 2 12 is fixedly connected to the top of the base plate 3.

[0036] Reference Figures 4-6 The middle part of the rotating rod 5 is fixedly connected to one end of the torsion spring 4. When the rotating rod 5 rotates, it will compress the torsion spring 4. When resetting, the elastic force of the torsion spring 4 will be used to reset the rotating rod 5. The other end of the torsion spring 4 is fixedly connected to the inner wall of the base plate 3. The fixing block 6 is snapped into the inner wall of the ring groove 9. The dial 7 is fixedly connected to the left end of the rotating rod 5.

[0037] Working principle: First, when it is necessary to maintain the electronic components and parts inside the dial 1, simply use your finger to turn the dial 7 to rotate the lever 5 and the fixing block 6, so that the fixing block 6 rotates in the annular opening of the groove 9, making the two sets of fixing blocks 6 vertical. At this time, the fixing block 6 separates from the inner wall of the annular opening of the groove 9, allowing the lever 5 to separate from the vertical opening of the groove 9. Then, the entire dial 1 and the base plate 3 can be separated. When disassembling the dial 1 and the base plate 3, the airbag 11 is reset by the elastic force of the return spring 10, and the airbag 2 12 returns to its original shape.

[0038] When installing the base plate 3 to the dial 1, simply rotate the dial 7 in advance to rotate the lever 5 and the fixing block 6, keeping the fixing block 6 in a vertical position. Then, insert the lever 5 into the vertical opening of the annular groove 9, and simultaneously release the dial 7. The reverse elastic force of the torsion spring 4 will then return the lever 5 and the fixing block 6 to their original positions. Figure 5 In this state, the annular opening of the groove 9 is used to block the fixing block 6 and limit the entire base plate 3. During the installation of the dial 1 and the base plate 3, the top of the base plate 3 will squeeze the airbag 11, causing the airbag 11 to move upward and compress the return spring 10. The elasticity of the return spring 10 will keep the airbag 11 in contact with the top of the base plate 3. At the same time, the side of the airbag 12 will be squeezed by the inner side wall of the dial 1, and the elasticity of the airbag 12 will keep it in contact with the inner side wall of the dial 1.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
