Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-5, the present utility model provides a technical solution: a switch cabinet with a self-locking structure comprises a cabinet body 1, drawers 2 distributed at equal intervals from top to bottom are arranged in the cabinet body 1,

the two sides of the drawer 2 are welded with fixing strips 7, the wall body on the front surface of the cabinet body 1 is provided with a notch 101 for the penetration of the fixing strips 7, the fixing strips 7 are provided with long-strip-shaped sliding grooves 8, guide posts 9 are embedded in the sliding grooves 8, the top surface and the bottom surface of the guide posts 9 are provided with limit grooves 14 which are distributed at equal intervals,

the front of the drawer 2 is provided with a first groove 3, the groove wall of the first groove 3 is welded with a lug 4, the lug 4 is sleeved with two handles 5, two ends of each handle 5 are welded with a fixed shaft 6, and the fixed shafts 6 penetrate through the front wall of the drawer 2 and are inserted into the fixed strips 7;

the bearing in the fixed strip 7 is movably connected with a rotary rod 10, a fixed shaft 6 positioned in the fixed strip 7 is connected with the rotary rod 10 in a chain transmission manner, a gear 11 is fixed on the rotary rod 10 through a bayonet lock, the gear 11 is connected with a rack 12 in a meshed manner, and a limiting block 13 matched with the limiting groove 14 is welded at the bottom end of the rack 12.

Guide post 9 one end and the cabinet body 1 welded connection of notch 101 department, guide post 9 other end and cabinet body 1 inner wall welded connection, thereby guide post 9 can be fixed in on the cabinet body 1, and whole being the horizontality, fixed strip 7 can be on guide post 9 remove through sliding tray 8, guide post 9 not only can hold drawer 2 like this, make drawer 2 steady be fixed in cabinet body 1, and drawer 2 can carry out horizontal migration along two guide posts 9 moreover, thereby realize drawer 2's pull-out and push, rational in infrastructure.

The handle 5 is "U" type structure, and two handle 5 symmetries set up, have seted up second recess 16 on the handle 5, handle 5 structural design for after two handle 5 merge, be convenient for grasp, thereby be convenient for pull out drawer 2, the setting of second recess 16, the finger of being convenient for inserts, and then can pull handle 5 and rotate in first recess 3.

The fixing strip 7 is of a hollow structure, a guide rod 15 is welded and connected to the inner wall of the fixing strip 7, a hole groove for the insertion of the guide rod 15 is formed in the top surface of the rack 12, a spring is sleeved on the guide rod 15, two ends of the spring are connected with the rack 12 and the wall body of the fixing strip 7 in a welded mode, a through groove is formed in the wall body of the fixing strip 7, a limiting block 13 penetrates through the through groove and stretches into the limiting groove 14, when the drawer 2 needs to be opened, two handles 5 are pulled in sequence, so that the two handles 5 rotate by 90 degrees and are combined together, at the moment, the two handles 5 can be held, when the handles 5 rotate, the fixing shaft 6 can be driven to rotate synchronously, when the fixing shaft 6 rotates, the rotating rod 10 can be driven to rotate in the fixing strip 7 through a chain transmission mechanism, the rotating rod 10 can drive the gear 11 to rotate synchronously, the gear 11 can move vertically along with the gear 11 through the meshing action of the gear 12, and then the gear 12 pulls the limiting block 13 to move out of the limiting groove 14, so that the limiting block 13 can be separated from the guide post 9, and the drawer 2 can be pulled to move;

the guide rod 15 is arranged, so that the movement of the rack 12 can be limited, the rack 12 is prevented from deflecting when moving, and the rack 12 can be ensured to rapidly drive the limiting block 13 to be pulled out of the limiting groove 14;

when rack 12 drives stopper 13 and takes out from spacing inslot 14, rack 12 can compress the spring, after drawer 2 stops at the pulling-out in-process, and handle 5 is loosened, the spring is restored to nature rectangular by compression this moment, rack 12 resets and drives rotary rod 10 counter-rotation through gear 11, rotary rod 10 can drive fixed axle 6 counter-rotation through chain drive, and then fixed axle 6 can drive handle 5 and reset, the in-process again, stopper 13 can insert in spacing inslot 14 again, under the effect of stopper 13 and spacing inslot 14, drawer 2 is locked, can't realize free movement.

Because the handles 5 are two, when one handle 5 is pulled, the limiting block 13 is inserted into the limiting groove 14, the drawer 2 still cannot be pulled out, and only after the two handles 5 are pulled, all the limiting blocks 13 can be moved out from the limiting block 13, and the drawer 2 can be pulled.

The limiting block 13 can not be directly gripped to be pulled in the first groove 3 around the convex block 4, so that a hidden structure is realized, and the handle 5 is prevented from being loosened or damaged due to repeated mistaken pulling.

The rack 12 and the limiting block 13 are perpendicular to the horizontal plane, the fixing strip 7 and the limiting groove 14 are cylindrical, the rack 12, the limiting block 13 and the limiting groove 14 are vertically distributed, the drawer 2 is pulled out in the direction perpendicular to the three, after the limiting block 13 is inserted into the limiting groove 14, the limiting groove 14 limits the displacement of the limiting block 13 in the horizontal direction, and the limiting block 13 is matched with the limiting groove 14 to limit the movement of the drawer 2, so that the overall safety is improved.

Although the present utility model has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present utility model.
