The drawer-type low-voltage switch cabinet with an external protection structure injects cold air into the low-voltage switch cabinet body through a refrigeration compressor, which is convenient for improving the heat dissipation performance of the drawer-type low-voltage switch cabinet with an external protection structure.

[0004] However, the above patent still has certain problems during use. The low-voltage switch cabinet will open some heat dissipation holes to facilitate heat dissipation. However, due to the excessive number of electronic components inside the low-voltage switch cabinet, a large amount of heat energy will accumulate inside after long-term use and cannot be dissipated in time. At the same time, there is no protective structure for the pulled-out box, which shortens the service life of the low-voltage switch cabinet. Therefore, a drawer-type switch cabinet with a protection mechanism is now needed. Summary of the invention

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides: a drawer-type switch cabinet with a protection mechanism, such as Figure 1-Figure 7As shown, it includes a switch cabinet body 1, a switch cabinet body 1, and a group of bellows 5 are respectively installed on both sides of the switch cabinet body 1. A plurality of groups of second slots 8 are opened on the front side of the switch cabinet body 1, and a plurality of groups of limit wheels 9 are rotatably installed on both sides of the inner wall of the second slots 8. A group of installation drawers 14 are slidably inserted inside each group of second slots 8, and a locking cover 22 is fixedly installed on the outer end of each group of installation drawers 14; two groups of storage slots 10 are symmetrically opened inside each group of second slots 8, and a group of limit blocks 11 are movably installed inside each group of storage slots 10, and two groups of bottom slots 18 are symmetrically opened at the bottom of the installation drawer 14, and the limit blocks 11 are located inside the bottom slots 18 and slide in a fit.

[0026] Preferably, a first slot 2 is opened in the middle of the left and right sides of the switch cabinet body 1, a plurality of groups of air inlets 3 are symmetrically opened on the left and right sides of the switch cabinet body 1, an exhaust outlet 4 is opened in the lower front part of the switch cabinet body 1, and the first slots 2 opened on the left and right sides of the switch cabinet body 1 cooperate with the plug plate installed on one side of the bellows 5 to ensure the limit of the installation of the bellows 5. At the same time, the air inlet 3 opened on the side of the switch cabinet body 1 ensures that cold air can be sent in when the bellows 5 is working, so as to exchange the high temperature inside the switch cabinet body 1, and send the high temperature out from the exhaust outlet 4, so that the inside of the switch cabinet body 1 is stable and balanced.

[0027] Furthermore, a plug plate is installed at the center of one side of the bellows 5 corresponding to the switch cabinet body 1, and a plurality of docking air vents 6 are opened at the positions of each group of air inlets 3 on one side of the switch cabinet body 1. A filter screen 7 is installed through the outside of the bellows 5, and the plug plate is plugged in and installed in the first slot 2. The docking air vents 6 are inserted into the inside of the air inlet 3 and installed. The docking air vents 6 opened on one side of the bellows 5 can be inserted into the inside of the air inlet 3 to complete the positioning of the bellows 5. In addition, the filter screen 7 installed through the outside of the bellows 5 can prevent foreign matter from entering the inside of the switch cabinet body 1, thereby reducing the impact on the electrical parts inside the switch cabinet body 1.

[0028] Furthermore, an inclined surface is provided on the upper surface of the limit block 11, and a limit column 12 is fixedly installed on the lower surface of the limit block 11. Both ends of the limit column 12 are rotatably inserted into the storage groove 10, and a support spring 13 is fixedly installed on the lower surface of the limit block 11. The bottom end of the support spring 13 is fixedly installed inside the storage groove 10. The inclined surface on the upper surface of the limit block 11 can cooperate with the bottom groove 18 at the bottom of the installation drawer 14 to prevent the installation drawer 14 from being directly pulled out. At the same time, due to the limit column 12 installed on one side of the lower surface of the limit block 11, the limit block 11 can be rotated. When the installation drawer 14 is pulled outward under a large force, the bottom groove 18 exerts force on the limit block 11 outward, compressing the support spring 13 at the bottom of the limit block 11, thereby completing the extraction of the installation drawer 14.

[0029] It is worth mentioning that a connecting groove 15 is opened on the rear side of the installation drawer 14, and side grooves 16 are opened symmetrically on both sides of the installation drawer 14. The limiting wheel 9 is installed in close contact with the inner wall of the side groove 16, and a number of ventilation holes 17 are opened symmetrically on both sides of the installation drawer 14. The limiting wheel 9 rotatably installed inside the second slot 8 limits the movement of the installation drawer 14, and because the limiting wheel 9 is rotatably installed inside the side groove 16, the installation drawer 14 is more flexible and stable when it is pulled out. The connecting groove 15 opened on the rear side of the installation drawer 14 enables the electrical parts installed inside the installation drawer 14 to be stably connected with the connecting wires inside the switch cabinet body 1, thereby avoiding loose connection when the installation drawer 14 is pulled out.

[0030] Specifically, two groups of limit seats 19 are symmetrically installed inside the installation drawer 14, and two groups of mounting frames 20 are slidably installed inside the installation drawer 14. A group of anti-skid rubber pads 21 are respectively installed at both ends of the mounting frames 20. The anti-skid rubber pads 21 are inserted into the limit seats 19 and movably installed. The limit seats 19 limit the mounting frames 20. The anti-skid rubber pads 21 at the bottom of the mounting frames 20 can limit the mounting frames 20 after being inserted into the limit seats 19. The installation of electrical parts can be changed and adapted by moving the mounting frames 20. The locking cover 22 installed on the outside of the installation drawer 14 protects the installation drawer 14, and the handle 23 installed at the front end of the locking cover 22 is used to assist in pulling out the installation drawer 14 as a whole.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
