[0024] The positioning assembly comprises a fixed plate 7, a movable rod 8, a movable plate 9, a disc 10, a connecting rope 13, a lifting plate 14, a positioning block 15, a first spring 17 and a second spring 18, the fixed plate 7 is fixed to the upper side inside the movable cavity 6, the movable rod 8 is movably embedded on the fixed plate 7, the movable plate 9 and the disc 10 are respectively fixed to the upper and lower ends of the movable rod 8, the first spring 17 is connected between the movable plate 9 and the fixed plate 7, and the first spring 17 is sleeved outside the movable rod 8, the lifting plate 14 is movably arranged on the lower side of the fixed plate 7, the positioning block 15 is fixed to the bottom of the lifting plate 14, the movable cavity 6 is penetrated by a movable groove on the inside bottom, the positioning block 15 is matched with the movable groove and the positioning groove 16, a circular hole 12 and a rectangular groove 11 are formed on the fixed plate 7, one end of the connecting rope 13 is fixedly connected with the disc 10, the other end is sequentially penetrated through the rectangular groove 11 and the circular hole 12, and is fixedly connected with the lifting plate 14, the second spring 18 is connected between the bottom of the fixed plate 7 and the lifting plate 14, and the second spring 18 is sleeved outside the connecting rope 13.
[0025] Through the elastic effect of the second spring 18, the lifting plate 14 is conveniently pressed downward, thereby driving the positioning block 15 to pass through the movable groove downward and be inserted into the inside of the positioning groove 16, so that the drawer body 2 is further positioned and fixed, and the drawer body 2 is prevented from being pulled out at will, wherein under the movable cooperation of the movable rod 8 and the fixed plate 7, the disc 10 is conveniently pressed downward, the connecting rope 13 is combined, the lifting plate 14 is pulled to move upward, thereby driving the positioning block 15 to move upward and be separated from the positioning groove 16, so that the user conveniently pulls out the drawer body 2 outward, and the use of the drawer is facilitated.
[0026] The fixed plate 7 is provided with a pulley block 19 on the upper side, two limiting rods 20 are relatively fixed in the rectangular groove 11, and the connecting rope 13 is sequentially penetrated between the two limiting rods 20 and the pulley block 19, so that the limiting rods 20 and the pulley block 19 effectively limit and guide the connecting rope 13, and the stability in the pulling process of the connecting rope 13 is ensured.
[0027] The guiding rod 21 is fixed to the inside rear side of the movable cavity 6, penetrates the lifting plate 14, and the lifting plate 14 is slidably matched with the guiding rod 21, so that the guiding rod 21 effectively limits and guides the lifting plate 14, and the stability in the up-down movement process of the lifting plate 14 is ensured, the notch 3 is penetrated by a strip-shaped groove on the inner wall bottom, and the movable plate 9 is matched with the strip-shaped groove.
[0028] Two slide rails 22 are oppositely arranged on the inner wall of the cabinet body 1, and a sliding block 23 is slidably arranged in the slide rail 22. The two sliding blocks 23 are fixed on the two sides of the outer wall of the drawer body 2. Through the sliding cooperation of the sliding block 23 and the slide rail 22, the drawer body 2 is conveniently pulled out. The drawer body 2 is provided with a drawer lock 24, and a lock hole is formed in the inner wall of the cabinet body 1. The lock rod of the drawer lock 24 cooperates with the lock hole. The notch 3 is elastically hinged with a baffle 25, which effectively shields the notch 3 and effectively prevents the movable plate 9 from being seen from the outside.
[0029] Embodiment:
[0030] When the drawer body 2 is locked, the user puts his hand into the notch 3. Under the cooperation of the movable rod 8 and the fixed plate 7, the movable plate 9 is pressed down to compress the first spring 17, and the disc 10 is moved downward, combined with the limiting rod 20 and the pulley set 19, one end of the connecting rope 13 is stably moved downward, thereby pulling the other end of the lifting plate 14 upward along the direction of the guide rod 21 to compress the second spring 18, and the positioning block 15 is moved to the inside of the movable cavity 6;
[0031] Then under the sliding cooperation of the sliding block 23 and the slide rail 22, the drawer body 2 is pushed into the cabinet body 1 until the first electromagnet 4 and the second electromagnet 5 are attached. At this time, the first electromagnet 4 and the second electromagnet 5 are energized by the external control switch, so that the first electromagnet 4 and the second electromagnet 5 are attracted together, thereby the drawer body 2 is attracted and fixed in the cabinet body 1;
[0032] When the drawer body 2 is completely pushed into the cabinet body 1, the positioning groove 16 is aligned with the movable groove. The movable plate 9 is released, and under the elastic action of the first spring 17, the movable plate 9 is driven upward to return to the initial position. At this time, the upper surface of the movable plate 9 is at the same horizontal plane as the inside bottom surface of the notch 3. At the same time, under the elastic action of the second spring 18, the lifting plate 14 is pressed downward, thereby driving the positioning block 15 to pass through the movable groove and insert into the positioning groove 16, further limiting and fixing the drawer body 2;
[0033] Finally, the drawer body 2 is locked through the drawer lock 24, and even if the drawer lock 24 is damaged during use, the drawer body 2 can still be stably maintained in the cabinet body 1 due to the cooperation of the first electromagnet 4, the second electromagnet 5, the positioning assembly and the positioning groove 16, and the first electromagnet 4, the second electromagnet 5, the positioning assembly and the positioning groove 16 are all hidden, combined with the shielding of the baffle 25 on the notch 3, so that the movable plate 9 is not easy to be found, the anti-theft property of the drawer body 2 is effectively improved, the defects that the existing drawer is generally not locked and is easily opened randomly during use and has low safety are solved, and the defects that the existing part of the drawer is locked through a mechanical lock or a password lock, the lock head of the mechanical lock or the password lock is easy to be damaged or pried open, the anti-theft effect is poor, and the safe use of the drawer is affected are solved.
