Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1 to 4, an embodiment of the present invention is a comparatively and expanded low-voltage switchgear, including a box body 100, four corners of the box body 100 are provided with L-shaped fixing notches 110 along a vertical direction, right angles of the L-shaped notches coincide with four corners of the original box body 100, a fixing plate 200 matched with the shape of the fixing notch 110 is installed at the fixing notch 110, and the fixing plate 200 can slide up and down along the fixing notch 110 to be adjusted and fixed; the upper end of the fixing plate 200 of the lower box 100 extends out and is inserted into the fixing notch 110 of the upper box 100 to realize the splicing of the upper and lower adjacent boxes 100; when the box 100 is required to be extended and installed at the upper side, the fixing plate 200 of the lower box 100 slides upward and is connected to the fixing notch 110 of the upper box 100, so that four corners of the upper box 100 are fixed, thereby ensuring that the upper box 100 does not slide in four directions.

The top of the box 100 is provided with a dovetail groove 120 which is transversely penetrated, and dovetail sliders 300 matched with the dovetail grooves 120 are inserted into the aligned dovetail grooves 120 on the transversely adjacent box 100 to realize the splicing of the left and right adjacent boxes 100. The adjacent boxes 100 are fixed by a dovetail slider 300 installed in the dovetail groove 120 of the two boxes 100. The dovetail groove 120 and the dovetail slider 300 can make the horizontally adjacent boxes 100 separate and must move along the horizontal direction, and the gravity of the boxes 100 can generate large friction in the horizontal direction, so that the boxes 100 are prevented from shaking and separating.

The box 100 installed at the bottom end can be connected and fixed with the ground through screws, so that the overall safety of the switch cabinet is further improved.

Specifically, the sidewall of the fixing gap 110 extends upward from the bottom to form a T-shaped sliding slot 130, and the sidewall is any abutting surface between the fixing gap 110 and the fixing plate 200. The T-shaped sliding groove 130 is not through in the vertical direction, and a T-shaped sliding block 210 matched with the T-shaped sliding groove 130 is arranged at the bottom end of the fixing plate 200. The T-shaped slider 210 is disposed at a bottom end thereof to determine a position where the T-shaped slider is assembled when the T-shaped slider slides on the fixing plate 200, thereby preventing the fixing plate 200 from being protruded upward at different heights. The top end of the fixing plate 200 is not provided with a T-shaped sliding block 210, so that the box body above can be conveniently inserted and expanded. The combination of the T-shaped sliding block 210 and the T-shaped sliding groove 130 enables the fixing plate 200 to be tightly fitted with the fixing notch 110, and at the same time, can keep sliding in the vertical direction to realize the splicing of the box 100. In other embodiments, the T-shaped sliding slot 130 and the T-shaped sliding block 210 may also be as long as the fixing plate 200 for better fixing effect.

Preferably, in order to enable the fixing plate 200 to be slidably engaged with the case 100 and then to be maintained at the engaged position, a first fixing screw 400 for fixing the position of the fixing plate 200 is disposed at a position corresponding to the fixing notch 110 in the case 100, specifically, a threaded hole extends outward in the case 100, an outer end of the threaded hole is disposed on a contact surface between the fixing notch and the fixing plate, and the position of the fixing plate 200 is fixed by increasing a friction force of the fixing plate 200 by screwing the first fixing screw 400. In other embodiments, the position of the fixing plate 200 may also be fixed by an interference fit between the T-shaped sliding slot 130 and the T-shaped sliding block 210.

Preferably, in order to facilitate the relative fixation between the slider and the dovetail groove 120, second fixing screws 500 for fixing the slider in the dovetail groove 120 are disposed in the casing 100 corresponding to the two ends of the dovetail groove 120, specifically, a threaded hole extends outwards in the casing 100, the outer end of the threaded hole is disposed on the joint surface of the dovetail slider 300 and the dovetail groove 120, and the dovetail slider 300 and the dovetail groove 120 can be fixed relative to each other by screwing the second fixing screws 500 by the first fixing screws 400. In other embodiments, the relative fixation of the dovetail slider 300 and the dovetail slot 120 may also be achieved using an interference fit.

To facilitate the use and storage of the single case 100, the fixing plate 200 is formed to have the same height as the case 100, and the fixing plate 200 can be mounted on the fixing notch 110 so that the case 100 forms a complete cube. When not splicing, the fixing plate 200 can be matched with the box 100 to form a cube for convenient storage, and meanwhile, the appearance is more attractive.

In order to ensure that the slider can be overlapped with the adjacent box 100 with enough length and the appearance of the box 100 is not affected, the dovetail slider 300 has the same length as the dovetail groove 120 and can be completely accommodated in the dovetail groove 120. When the casing 100 is not horizontally assembled, the dovetail slider 300 can be accommodated in the dovetail groove 120, and when necessary, it is drawn out from the dovetail groove 120 for use.

Because the needs that the cubical switchboard is satisfied to adjacent box 100 needs to dispose the electric wire usually after the concatenation, therefore the top surface in the box 100, the bottom surface all is provided with wire hole 140 with the side of controlling, wire hole 140 position symmetry about, the position symmetry of wire hole 140 is walked from top to bottom, thereby make wire hole 140 can correspond the intercommunication with wire hole 140 on the adjacent box 100, thereby the inside electric wire of cubical switchboard of being convenient for walks the line, be provided with detachable shielding cover 600 on the wire hole 140, in this embodiment, shielding cover 600 and walk and realize dismantling the connection through threaded connection between the wire hole 140, in other embodiments, shielding cover 600 also can adopt interference fit and walk wire hole 140 to realize dismantling the connection. The wiring holes 140 which are not needed to be used can be covered, and the isolation of the interior of the box body 100 from the external environment is ensured.

Preferably, in order to ensure stable operation of internal components and reduce the temperature of the box 100, the back of the box 100 is provided with heat dissipation fins 700 for assisting heat dissipation of the box 100.

The utility model discloses a theory of operation does: when the case 100 is expanded in the longitudinal direction, the fixing plate 200 is slid upward, the first fixing screw is screwed to fix the position of the fixing plate 200, and then the fixing plate 200 at the four corners of the expanded case 100 is pushed by the fixing plate 200 at the lower side to slide upward. When the box body 100 is expanded transversely, the sliding blocks slide out of the dovetail grooves 120 and are inserted into the dovetail grooves 120 of the adjacent box bodies 100, and second fixing screws in the two box bodies 100 are screwed to fix the sliding blocks 300 of the dovetail blocks and the dovetail grooves 120, so that the adjacent box bodies 100 are fixed. After the box 100 is spliced and expanded, the shielding cover 600 can be opened as required, so that the adjacent wiring holes 140 can be communicated for wiring.

The above embodiments are only used for illustrating the technical solutions of the present invention and are not limited thereto, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of the technical solutions of the present invention.
