Fixed bolt

Abstract

The invention discloses a fixed bolt which comprises a butt joint sleeve, a pulling cover, an elastic element and a clamping element, wherein the butt joint sleeve at one side of a sleeve body extends to form a fixed part; the interior of a sleeve body is provided with a through groove, an opening and a through hole, and the opening and the through hole are arranged at two sides of the through groove; the inner side wall of the through groove is annularly provided with a positioning part; the outer side of the opening of the butt joint sleeve is provided with the cover body of the pulling cover; the elastic element is arranged in the through groove of the butt joint sleeve; the clamping element is provided with a rod body one side of which is sleeved with the elastic element and then is fixedly connected with the pulling cover; the other side of the rod body extends to form a fixed head pushed and propped by the elastic element; the side wall, which is close to the propping surface, of the fixed head is annularly provided with a propping part, so that the butt joint sleeve is installed on a preinstalled first plate body, and after the fixed head of the clamping element is inserted and fixed in a plurality of clamping holes on a preinstalled second plate body so as to achieve positioning, if the pulling cover is pulled to drive the fixed head of the clamping element to extrude the elastic element, the positioning can be achieved by the fixed head through utilizing the propping part and the positioning part of the through groove of the butt joint sleeve, thus the pulling cover is convenient to disassemble and assemble without continuous application of force.

Description

technical field [0001] The invention relates to a fastening element, in particular to a fixing bolt, especially when the pull cover is forced to drive the displacement of the fastening element and compress the elastic element, the fastening element can use the positioning part of the outer wall of the fixing head and the inside of the docking sleeve The positioning portion penetrating through the groove forms a positioning, and since the clamping element does not need to continuously apply external force, it is convenient to carry out disassembly and assembly operations. Background technique [0002] At present, many products use screws or pins for positioning, such as drawers, machine boards and other products with telescopic structures. In order to use the pins or pins to make the slide rails and chutes form a position when they move to a specific position, the user is convenient. The operation can be carried out without moving the slide rail and the chute, such as desktop...
