Detailed Description
1. Referring to fig. 1 to 4, the main contents of the present invention are: an anti-loosening device is designed at an outlet of the electronic equipment extending out of a cable, and comprises a cable protective sleeve 1, a cable fastening ring 2 and a fastening screw 3; the device can adjust the size of the cable protective sleeve and the cable fastening ring according to the thickness of the extended cable, the cable outlet direction and other differences, and the cable bundle outlet mode so as to adapt to fastening different electronic component cables.
In this example, referring to fig. 3, the cable protection sleeve is an integrally formed part, which is a cylindrical body as a whole, and has two open ends and a cavity inside; the circumferential surface is provided with an opening, so that the cable protective sleeve is divided into a first annular cavity, the opening and a second annular cavity. The first ring cavity is defined to be embedded on the substrate, and the second ring cavity is defined to be not embedded on the substrate. The base body is provided with a circular groove, and the first annular cavity is embedded in the circular groove. The center of the circular groove is provided with a through hole, and the axis of the through hole is superposed with the axis of the cable protective sleeve.
The cable fastening ring is an annular body, and the side wall of the cable fastening ring is provided with a threaded hole; the cable fastening ring is positioned at the opening of the protective sleeve after being sleeved into the second annular cavity, the axial height of the cable fastening ring is smaller than that of the opening of the protective sleeve, and the cable fastening ring and the protective sleeve are firstly matched and stabilized; at this moment, the fastening ring belongs to an eccentric state, and the axis does not coincide with the axis of the protective sleeve.
After the cable penetrates through the base body, the cable fastening ring and the second annular cavity, the fastening screw is screwed; the end compresses tightly the lateral wall that the cable protection cover opening goes out soon, and then compresses tightly the cable, further continues to compress tightly cable tight loop inner wall, finally makes the cable compress tightly fixedly between protective cover and tight loop, plays locking effect.
When the electronic component is assembled, the piece 1 is pressed onto an outlet mounting base body (piece 5) of the electronic equipment, the matching surface is tightly attached, the opening expanding tool is used for expanding the opening, the piece 1 is firmly embedded on the piece 5, and then the piece 2 is embedded. When a cable (piece 4) is processed, the piece 4 penetrates out of the piece 1 and the piece 2 through the matching surface of the electronic equipment, the piece 2 is moved downwards by tightening the tightening piece 2 through the tightening screw (piece 3) at the lower part of the tightening piece 2, and the piece 4 is tightly pressed on the piece 1, so that the purpose of the tightening piece 4 is achieved.
In practical use, the sizes of the parts 1 and 2 and the cable outlet mode can be adjusted according to the diameters of the cables so as to meet the requirements of fastening different cables.
The structure comprises the following steps during assembly and use:
step 1: when the electronic equipment is assembled, the cable protective sleeve is tightly pressed and embedded on the installation substrate of the electronic equipment, which extends out of the matching surface of the cable outlet, and is sleeved in the cable fastening ring;
step 2: the electronic equipment extends out of the cable and penetrates out of the cable protective sleeve and the cable fastening ring through the matching surface;
