[0003] In the related art, since the components to be installed in the drawer of the withdrawable switch cabinet are heavy, the drawer in the cabinet is usually taken out, and then the components are installed in the drawer, and then reinserted into the drawer compartment after the installation is completed.

[0004] The following problems also exist in the prior art: when the operator replaces components, since the components installed in the drawer are heavy, the drawer is easily dropped due to gravity when it is pulled out. If the operator is not careful, the drawer and the components in the drawer may fall and be damaged, which may easily cause safety accidents in serious cases. There is still room for improvement. Utility Model Content

[0005] In order to improve the situation where a drawer equipped with components falls due to gravity when being pulled out from a switch cabinet, thereby damaging the drawer and components, and causing safety accidents in serious cases, the present application provides an intelligent low-voltage withdrawable switch cabinet.

[0006] The intelligent low-voltage withdrawable switchgear provided in this application adopts the following technical solutions:

[0007] An intelligent low-voltage withdrawable switch cabinet comprises a cabinet body, a drawer partition, a drawer and a limit assembly, wherein the drawer partition is fixedly connected to the cabinet body, a plurality of drawer partitions are formed with the drawer partitions, the drawer is slidably connected to the drawer partition and is integrally embedded in the drawer partition, the limit assembly comprises a first limit block and a second limit block, the first limit block is fixedly connected to a side of the drawer close to the drawer partition, the second limit block is a boss formed by stamping on a side of the drawer partition close to the drawer, and a side of the first limit block arranged along the withdrawal direction abuts against a side of the second limit block facing away from the withdrawal direction.

[0008] By adopting the above technical solution, when the operator pulls out the drawer, the first limit block abuts against the second limit block, and the second limit block limits the movement of the first limit block, so that the drawer stops at the opening of the drawer compartment, and then the operator applies force to take it down, which reserves a certain reaction time for the operator, reduces the probability of the drawer being affected by gravity without the support of the operator when being pulled out, improves the stability of the drawer when being pulled out, and greatly enhances safety.

[0009] Optionally, two opposite sides of the second limit block are provided with guide surfaces for the first limit block to abut and slide against.

[0010] By adopting the above technical solution, when the drawer is taken or placed, the first limit block abuts against the guide surface, so that the first limit block enters and exits the drawer compartment along the guide surface, avoiding the interference of the second limit block when the drawer is taken or placed, improving the sliding efficiency of the drawer in the drawer compartment, and reducing the operating difficulty of the operator when taking or placing the drawer.

[0011] Optionally, a third limit block is provided on the drawer partition, and the third limit block is fixedly connected to a side of the drawer partition close to the drawer, and a side of the first limit block facing away from the pulling-out direction abuts against a side of the third limit block arranged along the pulling-out direction.

[0012] By adopting the above technical solution, when the operator controls the drawer to move along the side opposite to the pulling-out direction, the first limit block abuts against the third limit block, thereby reducing the excessive sliding of the drawer in the drawer compartment and the collision in the cabinet body, causing damage to the cabinet body and the drawer, thereby increasing the service life of the drawer and reducing the failure rate.

[0013] Optionally, a positioning groove communicating with the outside is provided on a side of the third limiting block close to the second limiting block, the first limiting block is slidably connected in the positioning groove, and a side of the first limiting block facing away from the withdrawal direction abuts against a bottom wall of the positioning groove.

[0019] Optionally, the connecting bracket further includes fastening screws, some of which are sequentially inserted into the abutting portion and the cross beam of the base, and some of which are sequentially inserted into the abutting portion and the column.

[0020] By adopting the above technical solution, the fastening screws fix the abutment portion and the crossbeam of the base, and fix the abutment portion and the column, thereby fastening the connection between the connecting bracket and the cabinet body and further enhancing the stability of the connecting bracket.

[0021] Optionally, the cabinet is provided with a socket for plugging in components in the drawer, and the cabinet is provided with positioning holes for components of various models to be correctly plugged into the socket. The positioning holes are evenly arranged along the height direction of the cabinet and are provided on two opposite sides of the socket.

[0022] By adopting the above technical solution, positioning holes are provided on the cabinet, which reduces the problem of various types of components not matching the sockets when being plugged in, causing damage to the components and the sockets. This improves the safety of component plugging, enhances the service life of components and the sockets, and reduces misoperation during plugging.

[0023] Optionally, a limiting plate for limiting the movement of the drawer in a vertical direction is fixedly connected to a side of the drawer partition close to the drawer.

[0024] By adopting the above technical solution, when the drawer is installed in the drawer compartment, the sliders on the two back sides of the drawer are slidably connected between the limit plates on the two opposite sides, so that the limit plates limit the movement of the drawer, reducing the probability of the drawer falling due to the vibration of internal components, enhancing stability, and further positioning the components when they are inserted into the socket.

[0025] Optionally, the drawer and the drawer partition are both provided with heat dissipation holes for dissipating heat from components in the drawer.

[0026] By adopting the above technical solution, when components are plugged in and working in the cabinet, a large amount of heat is generated, and the heat inside the cabinet can be reduced through the heat dissipation holes, thereby facilitating the subsequent picking and placing operations of the operators, reducing the occurrence of malfunctions caused by heat in the cabinet, and improving the safety of the switch cabinet.

[0027] In summary, the present application includes at least the following beneficial technical effects:
