Description

Technical Field

[0001] The utility model discloses a watch case structure, in particular to a watch case structure that can prevent falling and scattering. Background Art

[0002] A pocket watch, also known as a fob watch, is a small timekeeping device that can be placed in a pocket or hung on clothing. It usually does not have a watch band but is fixed to clothing by a chain or pendant and is usually placed in the breast pocket, so it is called a "pocket watch".

[0003] A wristwatch, also called a watch, is a time measurement instrument worn on the wrist. It is not only a practical time tool but also often exists as a fashion accessory or a collectible.

[0004] Whether it is a pocket watch or a wristwatch, it generally includes a case, a movement, and a dial. The case is usually made of metal (such as stainless steel, gold, platinum, etc.), plastic, or ceramic. The dial is usually covered with glass or crystal to protect the movement and may also be inlaid with gemstones or decorated with delicate patterns. The case usually includes a case body and a back cover that are fixedly installed together. The installation methods of the case body and the back cover are diverse. Some are fixedly installed together by screws, some are fixedly installed together by screwing, and the simplest way is to snap the back cover and the case body together.

[0005] As people's requirements for the structure of watch products become more and more strict, especially in developed countries, it is proposed that when a watch drops normally from the height of human use, it is necessary to ensure that the back cover and the case body do not separate, that is, the overall structure of the watch cannot be scattered. If the back cover accidentally falls off and separates from the case body, the movement is easily exposed, and small parts or batteries of the movement are easily dropped. If picked up by a child accidentally and even swallowed by mistake, extremely serious consequences will occur. This poses a new challenge to the snap-fit structure. Whether it is a direct snap-fit or a snap-fit followed by gluing, it cannot guarantee the separation phenomenon after falling. How to solve this problem has become an urgent problem to be solved in the current watch product industry. Summary of the Invention

[0006] Aiming at the disadvantage that the back cover and the case body of the watch products in the above-mentioned existing technology are prone to separate after falling, the utility model provides a watch case structure that can prevent falling and scattering. A snap ring and a snap groove structure are arranged between the back cover and the case body, which can play an auxiliary connection role and effectively prevent the phenomenon of scattering between the back cover and the case body after falling.

[0007] The technical solution adopted by the present utility model to solve its technical problems is as follows: A watch case structure that prevents falling and scattering. The watch case structure includes a housing main body and a rear cover. The housing main body and the rear cover are cooperatively installed together.

Specific implementation manner

[0027] This embodiment is the preferred implementation manner of the present utility model. All others whose principles and basic structures are the same as or similar to this embodiment are within the protection scope of the present utility model.

[0028] Please refer to the attached Figure 1 to the attached Figure 6 , the present utility model mainly includes a housing main body 11 and a rear cover 21. The housing main body 11 and the rear cover 21 are installed together in cooperation. Clamping convex rings and clamping grooves are provided on the opposite surfaces of the housing main body 11 and the rear cover 21. The clamping convex rings are clamped in the clamping grooves, which can play an auxiliary fixing role through the clamping convex rings and the clamping grooves, ensuring that when the watch drops, the housing main body 11 and the rear cover 21 will not come apart.

[0029] In this embodiment, the clamping convex ring 13 is fixedly arranged on the housing main body 11, preferably integrally arranged with the housing main body 11. The clamping groove 22 is opened at the corresponding position on the rear cover 21, ensuring that when the housing main body 11 and the rear cover 21 are installed, the clamping convex ring 13 can be inserted into the clamping groove 22. Specifically in implementation, the clamping convex ring 13 can be fixedly arranged on the rear cover 21, and the clamping groove 22 can be opened at the corresponding position on the housing main body 11, which can also achieve the same function.

[0030] In this embodiment, the clamping convex ring 13 has an annular structure, and the cross-section of the clamping convex ring 13 is an inverted trapezoid, that is, the width at the connection position between the clamping convex ring 13 and the housing main body 11 is relatively narrow, and the width of the other end (i.e., the top) is relatively wide. The angle between the convex ring side wall 15 of the clamping convex ring 13 and the center line of the clamping convex ring 13 is 1° - 5°, preferably 3°. In this embodiment, a convex ring guiding inclined surface 14 is provided at the top of the clamping convex ring 13, and the inclination angle of the convex ring guiding inclined surface 14 (i.e., the angle between the convex ring guiding inclined surface 14 and the center line of the clamping convex ring 13) is 30° - 60°, preferably 45°. It can play a guiding role during the installation process, making it easier for the clamping convex ring 13 to be inserted into the clamping groove 22.

[0031] In this embodiment, an inner wall 23 and an outer wall 24 are fixedly arranged on the rear cover 21. An annular clamping groove 22 is formed between the inner wall 23 and the outer wall 24. The shape of the clamping groove 22 matches the shape of the clamping convex ring 13, enabling the clamping convex ring 13 to be just inserted into the clamping groove 22. The cross-section of the clamping groove 22 is also trapezoidal, matching the cross-section of the clamping convex ring 13. The angle between the groove side wall 25 of the clamping groove 22 and the center line of the clamping groove 22 is 1° - 5°, preferably 3°. In this embodiment, a groove guiding inclined surface 26 is provided at the opening of the clamping groove 22, and the inclination angle of the groove guiding inclined surface 26 (i.e., the angle between the groove guiding inclined surface 26 and the center line of the clamping groove 22) is 30° - 60°, preferably 45°. It can play a guiding role during the installation process, making it easier for the clamping convex ring 13 to be inserted into the clamping groove 22.

[0032] In this embodiment, the width of the top of the clamping convex ring 13 (i.e., the width of the widest part of the cross-section of the clamping convex ring 13) is greater than the width of the opening of the clamping groove 22 (i.e., the width of the narrowest part of the cross-section of the clamping groove 22).

[0033] When the utility model is assembled, the convex ring guiding inclined surface 14 on the clamping convex ring 13 contacts the groove guiding inclined surface 26 at the opening of the clamping groove 22, and force is applied to squeeze, causing a slight deformation of the inner wall 23 and / or the outer wall 24, so as to facilitate inserting the clamping convex ring 13 into the clamping groove 22. Then the inner wall 23 and / or the outer wall 24 return to the natural state, thus realizing the clamping and fixing between the rear cover 21 and the housing main body 11.

[0034] The structure of the utility model can be applied to a pocket watch. A hanging buckle 12 is fixedly arranged on the outer side of the housing main body 11 for connecting the pocket watch chain. Specifically, in implementation, the structure of the utility model can also be applied to a wristwatch structure or other watches. According to different application occasions, different watch cores and watch dials can be installed in the housing main body 11. The watch core and the watch dial adopt conventional structures, such as: electronic watch, quartz watch, mechanical watch, radio wave watch and other watch cores are all acceptable.

[0035] The utility model is provided with a clamping convex ring and a clamping groove structure between the rear cover and the main body of the housing, which can play a role in auxiliary connection and effectively prevent the phenomenon that the rear cover and the main body of the housing are separated after falling. The utility model is provided with corresponding guiding inclined surfaces at the connection position between the rear cover and the main body of the housing, which can make its installation smoother.
