[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] The embodiment of the present utility model provides a drawer-type wiring cabinet anti-detachment and interlocking structure, as Figures 1-6 shown, including a cabinet body 1 and a drawer frame 2. There are multiple drawer frames 2, and the drawer frames 2 are slidably inserted into the interior of the cabinet body 1. One end of the drawer frame 2 located inside the cabinet body 1 is slidably inserted with two support frames 3. The inner depth of the cabinet body 1 is equal to the length of the drawer frame 2. The multiple drawer frames 2 are adjacent to each other and distributed inside the cabinet body 1. The upper surface of the drawer frame 2 is concave. The two support frames 3 inside the same drawer frame 2 are symmetrically distributed on both sides of the concave structure of the drawer frame 2, so that the two sides of the drawer frame 2 are evenly stressed. One end of the support frame 3 located outside the drawer frame 2 is fixed to the inner wall of the cabinet body 1.

[0024] An inner strip 4 is slidably inserted into the support frame 3. One end of the inner strip 4 is fixed to the inner wall of the drawer frame 2. The upper and lower surfaces of the inner strip 4 are both concave. A plurality of force-bearing wheels 14 are slidably inserted into the upper and lower concave portions of the inner strip 4. The circumferential surface of the force-bearing wheel 14 is in rolling contact with the support frame 3. When the drawer frame 2 moves relative to the cabinet body 1, the inner strip 4 moves relative to the support frame 3, and the force-bearing wheel 14 rolls to reduce the resistance generated when the inner strip 4 and the support frame 3 move relative to each other.

[0025] A misalignment strip 5 is slidably inserted inside the inner strip 4. The misalignment strip 5 is elastically connected to the inside of the drawer frame 2. The misalignment strip 5 elastically connected to the drawer frame 2 has a tendency to move outward from the inner strip 4. One end of the drawer frame 2 located outside the cabinet body 1 is provided with a cavity 7. One end of the misalignment strip 5 away from the cabinet body 1 is located inside the cavity 7. The upper surface of the misalignment strip 5 is concave. A plurality of inclined plane push blocks 6 are fixed inside the concave structure of the misalignment strip 5. A through plate 8 is arranged on the side of the inclined plane push block 6 away from the cabinet body 1. The upper surface of one end of the inclined plane push block 6 away from the cabinet body 1 is an inclined plane, and the upper surface of the other end of the inclined plane push block 6 is a flat surface. The plurality of inclined plane push blocks 6 inside the misalignment strip 5 are evenly distributed at equal distances. The lower end of the through plate 8 is elastically connected to the inner bottom wall of the misalignment strip 5. The upper end of the through plate 8 slidably penetrates the inner top wall of the inner strip 4. A plurality of slots 9 are provided on the inner top wall of the support frame 3. When the drawer frame 2 contacts the inner wall of the cabinet body 1, the misalignment strip 5 is pushed completely into the support frame 3. The misalignment strip 5 pushes the through plate 8 upward through the inclined plane of the inclined plane push block 6. When the through plate 8 moves to the horizontal plane of the inclined plane push block 6, the through plate 8 is inserted into the slot 9. A contact wheel 15 is rotatably connected to the lower end of the through plate 8. The through plate 8 is vertically arranged. The size of the slot 9 is adapted to the size of the through plate 8. The contact wheel 15 reduces the resistance received when the through plate 8 moves relative to the inclined plane push block 6.

[0026] Two insertion plates 11 are arranged inside the cavity 7. One ends of the two insertion plates 11 close to each other are elastically connected. The two elastically connected insertion plates 11 have a tendency to move away from each other. A through groove 10 penetrating through the front and back is provided on the back surface of one end of the misalignment strip 5 away from the cabinet body 1. One ends of the two insertion plates 11 located inside one cavity 7 away from each other are both triangular ends. The surface of the triangular end of the insertion plate 11 away from the cabinet body 1 is an inclined plane. An elliptical ring plate 12 is arranged inside the cavity 7 and between the two insertion plates 11. One end of the elliptical ring plate 12 close to the cabinet body 1 is an elliptical concave structure. Two round rods 13 are arranged inside the elliptical concave of the elliptical ring plate 12. The two round rods 13 are respectively rotatably connected to the two insertion plates 11. One end of the elliptical ring plate 12 away from the cabinet body 1 rotatably penetrates the inner wall of the cavity 7. When the misalignment strip 5 completely enters the inner strip 4, the triangular ends of the insertion plates 11 coincide with the through groove 10. The two insertion plates 11 inside the cavity 7 are inserted into the through groove 10 under elastic connection, so that the misalignment strip 5 can no longer move relative to the inner strip 4. When the elliptical ring plate 12 is rotated so that the short diameter end is horizontal, the insertion plate 11 is pulled away from the through groove 10 through the round rod 13, and the drawer frame 2 can be pulled out of the cabinet body 1.

[0027] Working principle: When the drawer frame 2 is located outside the cabinet body 1, the long diameter end of the elliptical concave shape of the elliptical ring plate 12 is in a horizontal state. When the drawer frame 2 is inserted into the cabinet body 1, the dislocation strip 5 gradually moves into the inner strip 4 by contacting the inner wall of the cabinet body 1. The dislocation strip 5 drives the inclined plane push block 6 to move. The through plate 8 gradually moves upward under the push of the inclined plane push block 6. When the dislocation strip 5 completely enters the inner strip 4, the through plate 8 is inserted into the upper slot 9 under the action of the inclined plane push block 6. At the same time, the insertion plate 11 coincides with the through slot 10. The two insertion plates 11 in one cavity 7 are inserted into the through slot 10 under elastic connection, so that the dislocation strip 5 cannot be dislocated and separated from the inner strip 4, fixing the positions of the support frame 3, the inner strip 4 and the dislocation strip 5. When it is necessary to pull the drawer frame 2 out of the cabinet body 1, control the elliptical ring plate 12 to rotate, so that the round rod 13 moves in the elliptical concave structure of the elliptical ring plate 12. When the short diameter end of the elliptical ring plate 12 contacts the round rod 13, pull the insertion plate 11 to disengage from the through slot 10, and the drawer frame 2 can be pulled away from the cabinet body 1.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
