[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0028] Depend on Figure 1 , Figure 2 and Figure 3 As shown, a watch case that is easy to disassemble and assemble comprises an upper shell 1, a lower shell 2, a fixed inner ring 3 and a matching groove 4. The fixed inner ring 3 is fixedly installed at the bottom end of the upper shell 1, the lower shell 2 is arranged below the upper shell 1, and the matching groove 4 is symmetrically provided on the upper surface of the lower shell 2. A locking mechanism 5 is symmetrically fixedly installed inside the fixed inner ring 3. The locking mechanism 5 comprises a moving groove 51, a moving plate 52, a clamping block 53, a first spring 54 and a locking plate 55. The moving groove 51 is opened inside the fixed inner ring 3, the moving plate 52 is slidably installed inside the moving groove 51, the clamping block 53 is fixedly installed on the surface of the moving plate 52, the side of the moving plate 52 is provided with a first spring 54, and the locking plate 55 is fixedly installed inside the matching groove 4. The locking mechanism 5 is used to quickly complete the assembly between the shells, and a pushing mechanism 6 is symmetrically fixedly installed inside the lower shell 2. The pushing mechanism 6 is used to release the connection between the upper shell 1 and the lower shell 2. A sealing mechanism 7 is fixedly installed on the surface of the lower shell 2. The sealing mechanism 7 is used to strengthen the sealing between the upper shell 1 and the lower shell 2.

[0029] During use, the upper shell 1 and the lower shell 2 are fitted together, and then the position of the upper shell 1 and the lower shell 2 is quickly locked by using the locking mechanism 5. As the upper shell 1 and the lower shell 2 gradually approach each other, the locking block 53 will automatically retract into the movable groove 51 due to the squeezing of the locking plate 55 inside the matching groove 4. When the upper shell 1 and the lower shell 2 are completely fitted together, the position of the locking block 53 is no longer squeezed by the locking plate 55 and will automatically pop out under the action of the first spring 54, and form a locking connection under the cooperation of the matching groove 4 and the locking plate 55, completing the rapid installation and combination of the shell. When the shell needs to be disassembled, the locking connection of the locking mechanism 5 can be released by using the pushing mechanism 6. Finally, the sealing mechanism 7 is used to ensure the sealing of the upper shell 1 and the lower shell 2 when connected, thereby improving the working efficiency of the equipment itself.

[0030] By the attached Figure 4 As shown, in this embodiment, the block 53 is trapezoidal in shape as a whole, and is used for automatically retracting the block 53 into the movable groove 51 after being squeezed by the lower component. During use, by limiting the shape of the block 53, when the block 53 is squeezed by the locking plate 55 at the bottom, it can automatically retract into the movable groove 51 without the need for being pushed by other components.

[0031] By the attached Figure 4 As shown, in this embodiment, limit blocks are symmetrically fixedly installed at the side openings of the movable groove 51, and the spacing between the limit blocks is larger than the width of the block 53 itself and smaller than the width of the movable plate 52 itself. During use, the limit blocks are designed to limit the distance that the movable plate 52 moves inside the movable groove 51, thereby ensuring the stability of the movable plate 52 during operation.

[0032] By the attached Figure 5 As shown, in this embodiment, the pushing mechanism 6 includes a pushing groove 61, a pushing plate 62, a pressing rod 63 and a second spring 64. The pushing groove 61 is opened inside the lower shell 2, the pushing plate 62 is slidably installed inside the pushing groove 61, the pressing rod 63 is fixedly installed at the bottom end of the pushing plate 62, the pressing rod 63 is slidably connected to the lower shell 2, and the second spring 64 is sleeved on the outside of the pressing rod 63.

[0033] During use, by pressing the pressing rods 63 on both sides at the same time, the pressing rods 63 push the pushing plate 62 inside the pushing groove 61 to slide, allowing the pushing plate 62 to enter the matching groove 4 to push and squeeze the card block 53, and push the card block 53 back into the movable groove 51, so that the card connection effect of the locking mechanism 5 itself can be released, and the disassembly of the components can be completed.

[0034] By the attached Figure 5 As shown, in this embodiment, the pushing groove 61 and the matching groove 4 are interconnected to assist the pushing plate 62 to enter the matching groove 4. During use, it is convenient for the pushing plate 62 to pass through the pushing groove 61 and enter the matching groove 4 to push the block 53.

[0035] By the attached Figure 6 As shown, in this embodiment, the sealing mechanism 7 includes a sealing groove 71, a sealing ring 72, a supporting gasket 73 and a sealing rubber ring 74. The sealing ring 72 is fixedly installed on the upper surface of the lower shell 2, the supporting gasket 73 is fixedly installed on the top of the lower shell 2, and a sealing groove 71 is opened on the lower surface of the fixed inner ring 3. The sealing groove 71 and the sealing ring 72 are slidably plugged, and a sealing rubber ring 74 is arranged between the sealing groove 71 and the sealing ring 72.

[0036] During use, the upper shell 1 and the lower shell 2 are fitted together so that the sealing groove 71 and the sealing ring 72 are plugged into each other. Then, the sealing rubber ring 74 between the sealing groove 71 and the sealing ring 72 is used to enhance the sealing effect when the upper shell 1 and the lower shell 2 are connected. Finally, the supporting gasket 73 is used to support the timing instrument inside the upper shell 1.

[0037] By the attached Figure 6 As shown, in this embodiment, the height of the support gasket 73 itself is greater than the height of the sealing ring 72 itself, and the protruding portion of the support gasket 73 is used to support the internal components of the upper shell 1. During use, it can provide stable support for the timing instrument inside the upper shell 1 and provide certain protection for the operation of the timing instrument.

[0038] By the attached Figure 1 As shown, in this embodiment, limiting columns are equidistantly fixedly installed on the bottom end of the upper shell 1, and limiting grooves are equidistantly provided inside the lower shell 2. The limiting columns are slidably plugged into the limiting grooves to assist in positioning the upper shell 1 and the lower shell 2 when connected. During use, they are used to assist in quickly fitting the upper shell 1 and the lower shell 2 together, thereby speeding up the assembly of the equipment.

[0039] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
