Description

Technical Field

[0001] The utility model relates to the technical field of electrical boxes, in particular to a wall-mounted electrical box. Background Art

[0002] Wall-mounted electrical box, also called wall-mounted distribution box or wall-mounted control box, is an electrical device installed on the wall, used to distribute electrical energy, control circuits and protect electrical equipment. They are widely used in schools, offices, hospitals, factories, workshops, homes and other places.

[0003] After the existing wall-mounted electrical box is installed, the distance between the box and the wall is fixed. When the outside temperature is high, the heat inside the electrical box cannot be discharged quickly. The heat is easily accumulated behind the electrical box due to the obstruction of the wall, which makes it inconvenient to quickly discharge the heat near the rear of the electrical box. When the outside temperature is low, if the distance between the electrical box and the wall is large, the air flow will quickly take away the heat behind the electrical box, resulting in a low temperature inside the electrical box, affecting the performance of the electrical components inside it, and making it inconvenient to quickly adjust the distance between the electrical box and the wall according to usage requirements. Utility Model Content

[0004] The purpose of the utility model is to provide a wall-mounted electrical box to solve the problems raised in the above background technology.

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

[0006] A wall-mounted electrical box comprises an electrical box, a support assembly is movably provided at the rear of the electrical box, the support assembly comprises a connecting frame, hollow blocks are fixedly installed at the four corners of the connecting frame, an adjustment assembly is movably provided on one side of the hollow block, the adjustment assembly comprises a screw rod rotatably connected to the inside of the hollow block, a threaded block is screwed on the outer side of the screw rod, a transmission assembly is fixedly connected to the surface of one side of the connecting frame, and an air intake fan is fixedly embedded and installed on the surface of one side of the connecting frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Insert the external expansion stud into the wall, screw the nut sleeve onto the outside of the expansion stud, and twist the nut sleeve to tighten the two, so that the support assembly can be easily installed on the wall. When the holes of the two limit rings overlap, push the limit rod to insert the limit rod into the limit ring on one side of the nut sleeve to fix the nut sleeve and the hollow block, so as to prevent the nut sleeve from loosening due to self-rotation and improve the firmness during tightening.

[0015] 2. Remove the filter, turn the hexagonal nut to drive the No. 1 bevel gear to rotate, and through the transmission of the No. 2 bevel gear and the rotating shaft, the No. 3 bevel gear drives the screw to rotate, so that multiple screws rotate synchronously, and the threaded block slides on its surface. At this time, the two folding plates flip and fold to provide sliding limit for the threaded block, so as to quickly adjust the distance between the electrical box and the wall by fixing the electrical box at the support assembly and then rotating multiple screws synchronously. When the outside temperature is high, the distance between the electrical box and the wall is increased, and the air flow is accelerated to quickly discharge the heat at the rear of the electrical box. When the outside temperature is low, the distance between the electrical box and the wall is reduced to slow down the heat loss at the rear of the electrical box and adjust the heat dissipation speed of the electrical box to prevent the temperature from being too high or too low and affecting the performance of the internal electrical components.

[0025] Embodiment 1

[0026] like Figure 1-4 As shown, in this embodiment, a plurality of slots 101 are provided at equal angles on the rear surface of the electrical box 1, a threaded block 303 movably penetrates adjacent slots 101, and a filter screen 102 is movably embedded and installed at the center of the rear surface of the electrical box 1; a hexagonal groove 302 is provided on one end surface of the screw rod 301, a threaded sleeve 304 is fixedly installed on one side surface of the threaded block 303, and a nut 305 is screwed and connected to the outer surface of the threaded sleeve 304; a folding plate 306 is hinged on one side surface of the hollow block 202 and the threaded block 303, and one end of two adjacent folding plates 306 are hinged.

[0027] In this embodiment, the threaded block 303 is inserted into the slot 101, and the nut 305 is screwed from the inside of the electrical box 1 so that the nut 305 is screwed and tightened on the outside of the threaded sleeve 304, and the electrical box 1 is fixed on the outside of the threaded block 303, and then the screw 301 is turned to rotate so that the threaded block 303 slides on its surface.
