Description

Technical Field

[0001] The utility model relates to the technical field of control boxes, in particular to an explosion-proof control box with adjustable internal space. Background Art

[0002] Explosion-proof control boxes are commonly used in power engineering, used to hold related electrical components and equipment. Power control cabinets are divided into two types: indoor and outdoor. Large power control cabinets used indoors often need to store more electrical components. Most of the current explosion-proof control boxes are composed of a box body and a door. Multiple devices and various professional objects are placed in the control box.

[0003] At present, the internal space size of the control box is often fixed and cannot be adjusted. If some additional objects need to be placed in it, a new control box needs to be replaced, which is very troublesome. Therefore, the existing explosion-proof control box cannot adjust the internal space size and is unable to accommodate objects of different sizes and quantities. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides an explosion-proof control box with adjustable internal space, which overcomes the deficiencies of the prior art and effectively solves the problem that the explosion-proof control box in the prior art cannot adjust the size of the internal space and is thus not suitable for the placement of objects of different sizes and quantities.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Open the box door and separate it from the box body, and rotate the screw rod by turning the handle. The rotating screw rod cooperates with the thread between the internal threaded tube and cooperates with the connecting rod to move in the fixed tube, thereby driving the top cover to move up and down along the box body. The top cover drives the extension frame to expand and contract in the box body, thereby changing the size of the space in the box body. At the same time, according to the change in the size of the space in the box body, first loosen the fastening knob to make the fastening block away from the back of the box door. After adjusting the position of the extension plate in the box door, tighten the fastening knob to make the fastening block press against the back of the box door, tighten the position of the extension plate, so that the top of the extension plate abuts against the bottom of the top cover, and complete the overall adjustment.

[0008] Preferably, a first connecting block is fixed to the bottom of the fixing tube and the top of the connecting rod, and the two first connecting blocks are respectively connected and fixed to one side outer wall of the box body and one side outer wall of the top cover.

[0009] The fixing pipe and the connecting rod are connected to one side of the box body and the top cover through the first connecting block.

[0010] Preferably, a second connection block is fixed to the bottom of the internally threaded tube, and the second connection block is connected and fixed to the outer wall of the other side of the box body.

[0011] The internal threaded pipe is fixed to the other side of the box body through the second connecting block.

[0012] Preferably, a fixing block is rotatably connected to the top end of the rod wall of the screw rod, and a turning handle is fixed to the top end of the screw rod, and the fixing block is fixedly connected to the outer wall of the other side of the top cover.

[0013] The screw rod is rotated by turning the handle, and the rotating screw rod cooperates with the thread between the internal threaded tube to drive the top cover to move up and down along the box body.

[0014] Preferably, a U-shaped groove is provided on the top of the box body, and the U-shaped groove is matched with the extension frame.

[0015] The extension frame moves up and down along the U-shaped groove.

[0016] Preferably, a slide groove is provided on the back of the box door, and the width of the slide groove is greater than the outer diameter of the screw.

[0017] When the extension plate moves in the box door, the screw moves along the slide groove.

[0018] The beneficial effects of the utility model are:

[0019] The screw rod is rotated by turning the handle, and the rotating screw rod cooperates with the thread between the internal threaded tube and cooperates with the connecting rod to be inserted and moved in the fixed tube, thereby driving the top cover to move up and down along the box body. The top cover drives the extension frame to expand and contract within the box body, thereby changing the size of the space inside the box body, which effectively solves the problem in the prior art that the explosion-proof control box cannot adjust the size of the internal space, and thus cannot be used for the placement of objects of different sizes and quantities.
