[0016] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0017] Example: Please refer to Figure 1-5A positioning device for assembling a drawer slide rail assembly includes a cabinet 1, a drawer body 2 and a slide rail body 3. The slide rail body 3 is connected to the cabinet 1, and the drawer body 2 is slidably connected to the slide rail body 3. It also includes a positioning mechanism 4, through which the drawer body 2 is locked to prevent the drawer body 2 from automatically sliding out of the slide rail body 3. Specifically, the positioning mechanism 4 includes a driving assembly 5, a hook 6 and a hook plate 7. The driving assembly 5 is connected to the cabinet 1, the hook 6 is connected to the driving assembly 5, the hook plate 7 is installed at the bottom of the drawer body 2, and the hook 6 is movably connected to the hook plate 7. The driving assembly 5 drives the hook 6 to move so that the hook 6 hooks the hook plate 7, thereby fixing the drawer body 2; the driving assembly 5 includes a slide seat 5 01, slider 502, spring 503, connecting rod 504 and push rod 505, the slider 501 is fixedly connected to the cabinet 1, the slider 502 is slidably connected to the slider 501, the top of the slider 501 is provided with a third slide groove 14, the push rod 505 is slidably connected to the slider 501, the end of the push rod 505 is connected to the slider 502, pushing the push rod 505 to move inward, so that the slider 502 slides in the third slide groove 14; one end of the connecting rod 504 is rotatably connected to the slider 501, and the other end of the connecting rod 504 is connected to a lever, and the top of the slider 502 is provided with a first slide groove 8, the first slide groove 8 is set as a closed loop, and the end of the first slide groove 8 is recessed inwardly, and the lever and the first slide groove 8 are clearance-matched, that is, the lever can When the lever moves to the end of the first slide groove 8 and slides in a circular motion along the first slide groove 8, it automatically slides into the recess and gets stuck, thereby fixing the slider 502; one end of the spring 503 is fixedly connected to the slide seat 501, and the other end of the spring 503 is fixedly connected to the slider 502. If the slider 502 is pushed again, the lever automatically pops out of the recess under the action of the spring 503, and the slider 502 moves again; the hook 6 is connected to the slider 502, and the slider 502 moves when it moves, so that the hook 6 is hung on the hook plate 7, or detached from the hook plate 7; specifically, a connecting plate 9 is installed at the bottom of the slider 502, and a second slide groove 10 is provided on the connecting plate 9, and the hook 6 is connected to the shaft pin 11, and the shaft pin 11 The second slide groove 10 is matched with the clearance, that is, the shaft pin 11 can move back and forth along the second slide groove 10, and a limit plate 12 is installed at the bottom of the slide seat 501. The hook 6 is connected to the limit plate 12 through a rotating shaft. When the slider 502 moves, the hook 6 is driven to move. Under the action of the limit plate 12, the hook 6 rotates, so that the hook head end of the hook 6 moves upward or downward. The hook head end of the hook 6 moves upward until it hooks the hook plate 7, thereby realizing the locking of the drawer body 2. When the hook head end of the hook 6 moves downward, the hook 6 and the hook plate 7 are released, thereby realizing the unlocking of the drawer body 2; the surface of the hook plate 7 is provided with anti-slip grooves to increase the friction between the hook 6 and the hook plate 7, so that the drawer body 2 is locked more firmly;Since foreign matter is easily accumulated in the third chute 14 and the first chute 8 and is difficult to clean, a cover plate 13 is installed on the top of the slide seat 501. The cover plate 13 is fixedly connected to the slide seat 501 by bolts, and the cover plate 13 prevents foreign matter such as dust from falling into the third chute 14 and the first chute 8. ;

[0018] The working principle of this embodiment is as follows: when in use, when the drawer body 2 is pushed inward to the end, the hook 6 at the bottom will jam the drawer body 2, and at this time, the drawer body 2 cannot be pulled out directly, and the drawer body 2 needs to be pushed inward again so that the hook 6 releases the drawer body 2 before the drawer body 2 can be pulled out; specifically, when the drawer body 2 is pushed inward, the drawer body 2 contacts the push rod 505 and moves inward, the push rod 505 pushes the slider 502 to move along the third slide groove 14, the hook head end of the hook 6 moves upward and jams the hook plate 7, the lever on the connecting rod 504 moves along the first slide groove 8 to the end of the first slide groove 8 and automatically bounces into the recessed position, thereby fixing the slider 502, and at this time the hook 6 and the hook plate 7 are kept When the drawer body 2 is pushed inward again, the push rod 505 pushes the slider 502 to move, and the lever on the connecting rod 504 will automatically pop out from the recess of the first slide groove 8 on the slider 502 under the action of the spring 503, and the lever moves to the other end along the first slide groove 8. At this time, the axle pin 11 and the second slide groove 10 move relative to each other, and under the action of the limit plate 12, the hook head end of the hook 6 moves downward and disengages from the hook plate 7, so that the hook 6 releases the drawer body 2, so that the drawer body 2 can be pulled out; therefore, the drawer body 2 of the utility model will not slide out of the slide rail, thereby improving the usage experience and user experience.

[0019] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
