Description

Technical Field

[0001] This utility model relates to the field of watch case structure technology, and specifically discloses a limiting type watch case structure. Background Technology

[0002] A watch is a common item worn on the wrist. It is generally composed of a case, a glass plate, an internal movement or electronic structure, and hands. The watch case not only affects the overall appearance of the watch, but also the stability of the internal structure.

[0003] While conventional watch cases can meet general usage needs, during assembly, the cover is usually connected to the lower end of the case via threads or bolts. Threaded connections may loosen over time, resulting in poor sealing between the case and the cover. Bolted installations also suffer from bolt loosening over extended periods, lacking containment protection and thus resulting in poor water resistance. Therefore, a containment-type watch case structure is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a limiting type watch case structure, which increases the sealing performance between the case and the cover by cooperating with the sealing component and the limiting component, thereby improving the sealing and waterproof performance.

[0005] This utility model is implemented as follows: a limiting watch case structure includes a watch case and a watch cover threaded to the inner wall of the watch case, wherein the outer wall of the watch cover is provided with a limiting component and a sealing component.

[0006] The sealing assembly includes a first sealing ring installed on the inner wall of the watch case, a second sealing ring embedded in the lower end of the watch case, the upper end of the watch cover abutting against the first sealing ring, and a limiting ring whose upper end abuts against the second sealing ring fixedly connected to the outer wall of the watch cover.

[0007] The limiting component includes two symmetrically distributed support columns fixedly connected to the outer wall of the limiting ring. The outer wall of the limiting ring is fitted with a support ring. The outer wall of the support ring has through holes corresponding to the two support columns. Vertical rods are fixedly connected to both ends of the support ring. Through holes are opened on the outer walls of the two vertical rods. Two symmetrically distributed lugs are fixedly connected to the outer wall of the watch case. Slots are opened at the lower ends of the two lugs. Horizontal sliding grooves are opened through the inner walls of the two slots. Springs located inside the two horizontal sliding grooves are fixedly connected to the outer wall of the watch case. Drive rods are fixedly connected to the opposite ends of the two springs. Inserts inserted into the two through holes are fixedly connected to the outer walls of the two drive rods.

[0008] As a preferred embodiment of the limiting watch case structure of this utility model, a first magnet is installed at the opposite ends of the two inserts, and a second magnet is embedded in the inner wall of the two slots.

[0009] As a preferred embodiment of the limiting watch case structure of this utility model, each of the two driving rods has a crossbar fixedly connected to the opposite side of the spring, and the outer wall of the watch case has auxiliary holes that are adapted to the two crossbars respectively.

[0010] As a preferred embodiment of the limiting watch case structure of this utility model, the lower ends of the two lugs are provided with grooves communicating with the transverse sliding grooves, and the lower ends of the two drive rods are fixedly connected with push rods that are slidably connected to the two grooves respectively.

[0011] As a preferred embodiment of the limiting watch case structure of this utility model, the lower ends of both inserts are inclined.

[0012] As a preferred embodiment of the limiting watch case structure of this utility model, the first sealing ring and the second sealing ring are made of fluororubber or silicone rubber, and the cross-section of the first sealing ring and the second sealing ring are both annular structures.

[0013] The beneficial effects of this utility model are:

[0014] (1) Double sealing protection: The first sealing ring between the upper end of the cover and the inner wall of the case forms a primary seal, effectively preventing external liquids or dust from entering through the top gap; the second sealing ring between the upper end of the limiting ring and the lower end of the case forms a secondary seal, improving the sealing performance between the cover and the case.

[0015] (2) Anti-loosening locking mechanism: The support ring and the limit ring are precisely aligned through the insertion post and the insertion hole. When the vertical rod is inserted into the slot, it pushes the insertion block to compress the spring until the insertion block springs into the through hole to complete the self-locking. The spring preload maintains the rigid engagement between the insertion block and the through hole, avoiding the loosening of the cover due to vibration or impact, and ensuring the long-term stability of the seal.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-5 A limiting type watch case structure includes a watch case 1 and a watch cover 2 threadedly connected to the inner wall of the watch case 1. The outer wall of the watch cover 2 is provided with a limiting component and a sealing component.

[0025] The sealing assembly includes a first sealing ring 5 installed on the inner wall of the watch case 1, a second sealing ring 7 embedded in the lower end of the watch case 1, the upper end of the watch cover 2 abutting against the first sealing ring 5, and a limiting ring 16 whose upper end abuts against the second sealing ring 7 fixedly connected to the outer wall of the watch cover 2.

[0026] The limiting assembly includes two symmetrically distributed support columns 3 fixedly connected to the outer wall of the limiting ring 16. A support ring 4 is sleeved on the outer wall of the limiting ring 16. The outer wall of the support ring 4 has through holes 17 corresponding to the two support columns 3. Vertical rods 21 are fixedly connected to both ends of the support ring 4. Through holes 19 are opened through the outer walls of the two vertical rods 21. Two symmetrically distributed hanging ears 20 are fixedly connected to the outer wall of the watch case 1. Slots 8 are opened at the lower ends of the two hanging ears 20. Horizontal sliding grooves 18 are opened through the inner walls of the two slots 8. Springs 11 located inside the two horizontal sliding grooves 18 are fixedly connected to the outer wall of the watch case 1. Drive rods 10 are fixedly connected to the opposite ends of the two springs 11. Inserts 9 inserted into the two through holes 19 are fixedly connected to the outer walls of the two drive rods 10.

[0027] In this embodiment: When in use, the two sealing rings work together. When the watch cover 2 is closed, its upper end forms a primary seal with the first sealing ring 5 on the inner wall of the watch case 1, and the upper end of the limiting ring 16 on the outer wall of the watch cover 2 forms a secondary seal with the second sealing ring 7 at the lower end of the watch case 1. Through the cooperation of the two sealing points, the all-round seal between the watch case 1 and the watch cover 2 is achieved, preventing liquid or dust from entering.

[0028] The support ring 4 is fitted onto the outer wall of the limiting ring 16, and the two support posts 3 are inserted into the two insertion holes 17 respectively. At this time, the two vertical rods 21 are inserted into the two slots 8 respectively. During this process, the two vertical rods 21 squeeze the two inserts 9 respectively, and the inserts 9 compress the springs 11 until the two inserts 9 are inserted into the two through holes 19 respectively. The springs 11 return to their original state. At this time, the two vertical rods 21 can be limited by the cooperation of the two inserts 9 and the two through holes 19, thereby preventing the connection between the watch case 1 and the watch cover 2 from becoming loose.

[0029] As a technical optimization of this utility model, a first magnet 6 is installed at the opposite ends of the two insert blocks 9, and a second magnet 15 is embedded in the inner wall of the two slots 8.

[0030] In this embodiment, the stability of the insert 9 inside the slot 8 can be increased by the mutual attraction between the first magnet 6 and the second magnet 15.

[0031] As a technical optimization of this utility model, the two drive rods 10 are fixedly connected to the opposite side of each other with a crossbar 13 located inside the spring 11, and the outer wall of the watch case 1 is provided with auxiliary holes 12 that are adapted to the two crossbars 13 respectively.

[0032] In this embodiment: during the compression of the spring 11, the crossbar 13 will slide inside the auxiliary hole 12, thereby restricting the horizontal movement of the drive rod 10.

[0033] As a technical optimization of this utility model, the lower ends of the two lugs 20 are provided with slide grooves 14 that communicate with the transverse slide grooves 18, and the lower ends of the two drive rods 10 are fixedly connected with push rods that are slidably connected to the two slide grooves 14 respectively.

[0034] In this embodiment: when it is necessary to remove the insert 9 from the inside of the through hole 19, the spring 11 is squeezed by the push rod, so that the insert 9 moves into the inside of the transverse slide groove 18.

[0035] As a technical optimization of this utility model, the lower ends of both inserts 9 are set with inclined surfaces.

[0036] In this embodiment, the lower ends of both insert blocks 9 are inclined, which facilitates the vertical rod 21 to press the insert blocks 9 to move laterally.

[0037] As a technical optimization of this utility model, the first sealing ring 5 and the second sealing ring 7 are made of fluororubber or silicone rubber, and the cross-sections of the first sealing ring 5 and the second sealing ring 7 are both annular structures.

[0038] In this embodiment: the material of fluororubber / silicone rubber is maintained to ensure corrosion resistance and aging resistance, and to meet the long-term use requirements of the watch in humid and sweaty environments.

[0039] The working principle and usage process of this utility model: When in use, the watch cover 2 is threaded to the inner wall of the watch case 1. Its upper end forms a primary seal with the first sealing ring 5 of the inner wall of the watch case 1. The upper end of the limiting ring 16 on the outer wall of the watch cover 2 forms a secondary seal with the second sealing ring 7 at the lower end of the watch case 1. Through the cooperation of the upper and lower sealing points, the all-round seal between the watch case 1 and the watch cover 2 is achieved to prevent liquid or dust from entering.

[0040] When the threaded connection of the watch cover 2 to the inside of the watch case 1 reaches its limit position, the two support pillars 3 correspond exactly to the two insertion holes 17. The support ring 4 is placed on the outer wall of the limiting ring 16, and the two support pillars 3 are inserted into the two insertion holes 17 respectively. At this time, the two vertical rods 21 are inserted into the two slots 8 respectively. During this process, the two vertical rods 21 press the two inserts 9 respectively, and the inserts 9 compress the springs 11 until the two inserts 9 are inserted into the two through holes 19 respectively. The springs 11 return to their original state. At this time, the two vertical rods 21 can be limited by the cooperation of the two inserts 9 and the two through holes 19, thereby preventing the connection between the watch case 1 and the watch cover 2 from becoming loose.
