[0002] The electrical cabinet is made of steel and is used to protect the normal operation of components. The materials used to make the electrical cabinet are generally divided into hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are softer than hot-rolled steel plates and are more suitable for the production of electrical cabinets. Electrical cabinets are widely used and are mainly used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. In order to facilitate the classification and installation of electronic parts, some electrical cabinets are designed as drawers during production. When using, the electronic parts can be classified and installed in the corresponding drawers. When using this kind of electrical cabinet, in order to prevent the drawer from automatically sliding out due to external factors such as vibration, a locking structure needs to be installed to lock the drawer.

It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.
[0026] See also Figures 1 to 5 The present invention provides a self-locking device for an electric cabinet drawer, comprising a drawer body 1 and a base 2, the drawer body 1 being slidably connected to the base 2, a locking assembly being arranged between the drawer body 1 and the base 2, a limiting base 3 being arranged below the locking assembly on the base 2, the locking assembly comprising a limiting frame 4 assembled in the drawer body 1 and above the limiting base 3, a push plate 5 reciprocating in the horizontal direction on the limiting frame 4, a locking plate 6 being arranged at the rear end of the push plate 5 and slidably connected to the limiting frame 4 up and down, a push plate slide 7 being arranged upwardly inclined on the push plate 5, a locking slide 8 being arranged on the limiting frame 4 on one side of the push plate slide 7, a locking protrusion 9 being arranged on the locking plate 6, the locking protrusion 9 being connected to the push plate slide 7 and the locking slide 8, and a reset spring 10 being arranged between the push plate 5 and the limiting frame 4.
[0027] By setting a limit base 3, the sliding of the drawer body 1 on the base 2 can be limited, thereby ensuring the stability and reliability of the use of the drawer body 1. By setting a limit frame 4, the push plate 5 that reciprocates horizontally on the limit frame 4 drives the locking plate 6 to slide up and down on the limit frame 4. When the push plate 5 moves backward, the locking protrusion 9 slides in the push plate slide groove 7. Since the push plate slide groove 7 is set upwardly inclined, the backward movement of the push plate 5 will drive the locking protrusion 9 to slide upward in the push plate slide groove 7, and the locking slide groove 8 can limit the up and down movement of the push plate 5, so that the reciprocating push plate 5 can drive the locking plate 6 to slide up and down on the limit frame 4. The setting of the reset spring 10 can make the push plate 5 realize the reset action after being manually released, realize the self-locking of the drawer, and ensure the stability and reliability of the drawer.
[0028] The downward movement path of the bottom of the locking plate 6 is set behind the limit base 3. When the drawer needs to be locked, the push plate 5 is driven by the return spring 10 to move close to the front end of the drawer body 1, thereby driving the locking plate 6 to move downward to the rear of the limit base 3. The limit base 3 is used to limit the locking plate 6, and the push plate slide groove 7 is gradually raised to a horizontal height close to the front end of the drawer body 1. By gradually raising the push plate slide groove 7 to a horizontal height close to the front end of the drawer body 1, the locking plate 6 can be moved upward when the push plate 5 is pushed inward by the outside world, thereby facilitating the opening of the drawer and avoiding the situation where the drawer is accidentally opened due to accidental contact by the outside world.
[0029] Two groups of push plate limit frames 11 are symmetrically arranged on the limit frame 4, and the push plate 5 is slidably connected in the push plate limit frame 11. The reset spring 10 is arranged between the push plate limit frame 11 and the push plate 5 near the front end of the drawer body 1. By setting two groups of push plate limit frames 11, the use stability and reliability of the push plate 5 can be improved. The reset spring 10 is arranged between the push plate limit frame 11 and the push plate 5 near the front end of the drawer body 1, which can facilitate the replacement and maintenance of the limit spring and reduce the occupation of the internal working space of the drawer body 1.
[0030] A reset plate 12 is provided between the push plate limit frame 11 on the push plate 5 and the push plate 5. The reset spring 10 is sleeved on the reset plate 12, and the reset plate 12 is slidably connected to the push plate limit frame 11. The setting of the reset plate 12 can provide convenience for the installation and use of the reset spring 10, and it is also convenient for the replacement of the reset spring 10. The locking groove 8 is arranged along the vertical direction. By setting the locking groove 8 along the vertical direction, the sliding stability of the locking protrusion 9 in the locking groove 8 can be improved, so as to facilitate the locking or loosening of the locking plate 6.
[0031] The invention can limit the sliding of the drawer body on the base by arranging a limit base, thereby ensuring the stability and reliability of the use of the drawer body. By arranging a limit frame, a push plate that reciprocates horizontally on the limit frame drives the locking plate to slide up and down on the limit frame. When the push plate moves backward, the locking protrusion slides in the push plate slide groove. Since the push plate slide groove is arranged to be inclined upward, the backward movement of the push plate will drive the locking protrusion to slide upward in the push plate slide groove, and the locking slide groove can limit the up and down movement of the push plate, so that the reciprocating push plate can drive the locking plate to slide up and down on the limit frame. The setting of the reset spring can enable the push plate to realize the reset action after the push plate is manually released, thereby realizing self-locking of the drawer and ensuring the stability and reliability of the drawer.
[0032] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention.
