A drawer unit 7 is installed inside the inner cavity 6, and a pull-out mechanism 8 is provided between the drawer unit 7 and the inner cavity 6.

[0031] Specifically, the cross-sectional shape of the fixing strip 3 matches the square groove 4, one end of the extension spring 303 is fixed to the inner wall of the mounting hole 301, and the other end is fixed to one end of the limiting pin 304. The inner wall of the limiting pin 304 is slidably connected to the outer surface of the limiting pin 302, and its corresponding locking setting is set with the limiting pin hole 5.

[0032] In this embodiment, the fixing strip 3 is mainly used to contact the square groove 4, while the extension spring 303 is mainly used to provide elastic support for the limiting pin 304, causing the limiting pin 304 to move along the outer surface of the limiting pin 302 and gradually engage with the limiting pin hole 5, thereby achieving the function of combining and splicing the first cabinet 1 and the second cabinet 2, which facilitates subsequent handling.

[0033] It should be noted that cabinet 1 and cabinet 2 have the same shape and size.

[0034] In this embodiment, please refer to Figure 2 , Figure 3 and Figure 5 The pull-out mechanism 8 includes a locking post 801, a slide groove 802, a sliding support block 803, a guide groove 804, a guide block 805, and a support spring 806. The locking post 801 is fixedly installed on the left and right sides of the first cabinet 1. A compression spring 807 is embedded in the opposite side surface of the locking post 801. A guide rod 808 is provided inside the compression spring 807. A pull ring 809 is fixedly installed at the opposite end of the guide rod 808. The slide groove 802 is opened on the bottom inner wall of the inner cavity 6. The sliding support block 803 is set at the bottom of the drawer unit 7. The guide groove 804 is opened on the left and right sides inside the inner cavity 6. The guide block 805 is fixedly installed on the left and right sides of the drawer unit 7, and a guide hole 810 is opened on the opposite side surface of the guide block 805. The support spring 806 is fixedly installed on the front surface of the drawer unit 7.

[0035] Specifically, the sliding block 803 is located at the bottom front side of the drawer unit 7, and its outer surface slides in contact with the slide groove 802. The front end of the support spring 806 is in active contact with the front inner wall of the inner cavity 6. The rear inner wall of the guide groove 804 extends to the rear surface of the first cabinet 1, and it is adapted to contact the outer surface of the guide block 805. One end of the guide rod 808 is respectively attached to and passes through the inner wall of the locking post 801, the right side surface of the first cabinet 1 and extends into the interior of the guide groove 804, and it is inserted into the guide hole 810.

[0036] In this embodiment, the pull ring 809 is mainly used to drive the guide rod 808, causing the guide rod 808 to disengage from the guide hole 810. The compression spring 807 is mainly used to provide elastic tension to the guide rod 808, causing the guide rod 808 to make contact with the guide hole 810. The sliding block 803 is mainly used to form a sliding fit with the slide groove 802. The support spring 806 is mainly used to support the drawer unit 7 and the inner cavity 6, providing elastic thrust to the drawer unit 7, thereby achieving the function of conveniently pulling out the drawer unit 7 and meeting the user needs of the staff.

[0037] The working process of this utility model is as follows: When using a withdrawable high-voltage switchgear, cabinet 1 and cabinet 2 are moved sequentially to the desired positions, and then cabinet 1 and cabinet 2 are joined together. Cabinet 2 is moved so that the fixing strip 3 is in contact with the square groove 4. During this process, an external force is applied to the limiting pin 304, causing the limiting pin 304 to compress the extension spring 303 along the surface of the limiting pin 302 until the limiting pin 304 is completely submerged in the mounting hole 301. When the limiting pin 304 and the limiting hole 5 are on the same straight line, the compressed extension spring 303 gradually extends and drives the limiting pin 304 to engage with the limiting pin 302. When the locking hole 5 contacts the switch, the splicing operation between cabinet 1 and cabinet 2 is completed, providing convenience for the handling personnel. Furthermore, when it is necessary to pull out the drawer unit 7, an external force is applied to the pull ring 809. The pull ring 809 then moves the guide rod 808 and stretches the compression spring 807. The guide rod 808 gradually disengages from the guide hole 810. At this time, the compressed support spring 806 gradually extends and applies a supporting force to the drawer unit 7, causing the drawer unit 7 to slide along the sliding block 803 and the slide groove 802. This facilitates the operation of pulling out the drawer unit 7 and improves the practicality of the switch cabinet.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
