Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

The utility model relates to a quick mounting and fastening device for low-voltage electrical appliance products, which comprises a five-star hand wheel 1 and a square component 2, as shown in figures 1-3; the square component 2 is made of Q235 steel, the left end of the square component is square, and the right end of the square component is concave, so that the square component can be conveniently installed on the installation plate; the through hole 3 is arranged in the middle of the square component 2 and is communicated left and right, namely the through hole 3 penetrates through the square structure and the concave structure left and right, so that the installation pin of a low-voltage electrical appliance product can be conveniently inserted; the first threaded hole 4 is arranged inside the left end of the square component 2 and penetrates up and down, namely the first threaded hole 4 penetrates through the cube structure up and down. The five-star hand wheel 1 is screwed into the first threaded hole 4; the through hole 3 is communicated with the first threaded hole 4 in a crossed manner; the five-star hand wheel 1 is arranged in the first threaded hole 4, the upper end of the five-star hand wheel 1 is made of plastic materials, and the five-star petal structure is convenient for workers to manually screw the five-star hand wheel 1 into the first threaded hole 4, so that the installation pin of a low-voltage electrical appliance product can be fastened; the lower end of the five-star hand wheel 1 is of a threaded structure, and the lower end of the five-star hand wheel 1 is arranged in the first threaded hole 4; the length of the lower end of the five-star hand wheel 1 is greater than the distance between the through hole 3 and the upper end surface of the square component 2; the second threaded hole 6 is arranged in the upper end of the square component 2 and is communicated left and right, namely the second threaded hole 6 penetrates through the upper end of the square structure left and right, so that the fastening screw 5 can be conveniently screwed in to fasten a low-voltage electrical appliance product; the fastening screws 5 are arranged in the second threaded holes 6, and the two fastening screws are totally two and can tightly push the square component 2, so that the low-voltage electrical appliance product can be fastened more reliably.
