[0033] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0034] like Figure 1 to Figure 7 As shown, a latch that is easy to disassemble and assemble of the utility model comprises an inner bracket 1, an outer bracket 2 is installed corresponding to the inner bracket 1, a first screw 3 is installed between the inner bracket 1 and the outer bracket 2 to match each other, a locking mechanism 4 is installed between the inner bracket 1 and the outer bracket 2, and a handle mechanism 5 is installed to match the locking mechanism 4;

[0035] The inner bracket 1 is provided with a slot 101;

[0036] The outer bracket 2 is provided with two bayonet holes 201, the outer bracket 2 is provided with an arc-shaped limiting hole 202, and the outer bracket 2 is provided with a release hole 203 connected with one of the bayonet holes 201;

[0037] The locking mechanism 4 includes a lock core 401, the cross section of the lock core 401 is T-shaped, one end of the lock core 401 corresponds to the escape port 203, the lock core 401 is provided with two buckle columns 402, the lock core 401 is provided with a positioning port 403, a positioning block 404 is placed in the positioning port 403, the positioning block 404 is integrally connected with a convex block 405 whose specification and size match the card slot 101, the lock core 401 is installed with a spring 406, a locking screw 407 is installed between the lock core 401 and the positioning block 404, and the locking screw 407 passes through the axis of the lock core 401 and the positioning block 404;

[0038] The handle mechanism 5 includes a handle 501 placed in the arc-shaped limiting opening 202 . The handle 501 is provided with a buckle hole 502 whose specification and size match the buckle column 402 .

[0039] In this embodiment, when a latch that is easy to disassemble and assemble is used, it is used in conjunction with a side box, and a clamping column matching the size of the clamping port 201 is provided on the side box. The side box is a common item in the prior art, and this structure is not difficult to understand for technicians in the relevant field;

[0040] Place the inner bracket 1 inside the side box, place the outer bracket 2 outside the side box, place the locking mechanism 4 between the inner bracket 1 and the outer bracket 2, and then use the locking screw 407 and the first screw 3 to fix the inner bracket 1, the outer bracket 2 and the locking mechanism 4 to complete the installation;

[0041] When in use, the handle 501 is pulled. Under the limit of the arc-shaped limit opening 202, the moving distance and angle of the handle 501 are fixed. During the movement of the handle 501, the lock core 401 is cooperated with the buckle column 402 and the buckle hole 502, and the lock core 401 rotates along with the handle 501. The rotation of the lock core 401 causes the end of the lock core 401 to break away from the cooperation with the bayonet 201 and move to the position of the escape opening 203, thus completing the opening of the latch.

[0042] On the contrary, when closing is required, the handle 501 is returned to its original position, and the lock core 401 is returned to its original position. Because the angular rotation of the lock core 401 will drive the rotation of the positioning block 404, the protrusion 405 will also move with it, and under the effect of the spring 406, the protrusion 405 will be stuck in the slot 101 to fix the position. The user will also clearly feel the pause action, and the position of the handle 501 is fixed.

[0043] Preferably, both bayonet ports 201 are equipped with bushings 204. Such a design reduces the wear on the mating parts. In fact, the material selection of the bushings 204 may also be considered according to specific circumstances.

[0044] Preferably, the outer bracket 2 is installed with a shield 205, and a second screw 206 is matched and installed between the shield 205 and the outer bracket 2. With this design, the shield 205 can shield and protect the handle 501 to prevent accidental contact. In fact, protective measures and installation measures can also be considered according to specific circumstances.

[0045] Preferably, the shield 205 is integrally connected with the stopper 207 . Such a design enhances the blocking effect on the lock core 401 . In fact, the style and specification size of the stopper 207 may also be considered according to specific circumstances.

[0046] Preferably, the ends of the first screw 3 and the second screw 206 are both matched with sheaths. Such a design enhances the overall appearance. In fact, the material and style of the sheath may also be considered according to specific circumstances.

[0047] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
