Problems solved by technology

[0002] In the installation process of many parts, the method of extruding the fastener is used to fix. This method adopts the wedge principle, that is, two wedges with inclined surfaces that can cooperate with each other are matched together to play a pressing role. This device is very easy to use and has good fastening performance, but when you want to remove the fastened part for maintenance, the squeezed and fastened wedge is difficult to loosen and difficult to disassemble

Embodiment Construction

[0024] Such as figure 1 As shown, a fastening device includes two wedges that will be squeezed and fixed in the matrix 27 by the fastener 28. The slopes of the two wedges overlap and are tightly squeezed by mutual sliding between the two. Firmware 28, one of the two wedges is connected with a pressing dismounting part, and the pressing dismounting part presses on another wedge or the substrate, and the rotation of the pressing dismounting part drives the wedge connected to it to move, and the two wedges are loosened. Squeeze between wedges. The two wedges are respectively the first wedge 1 and the second wedge 2. The present invention defines the big head of the first wedge 1 and the second wedge 2 as the top and the small head as the bottom. As can be seen from the figure, this In the embodiment, the large end of the first wedge 1 is on the top, and the small end of the second wedge 2 is on the top.

[0025] Such as figure 1 , 2 , 3, 4, and 5, wherein the first wedge 1 is...

Abstract

The invention discloses a fastening device comprising a first wedge block and a second wedge block. The inclined surface of the first wedge block and the inclined surface of the second wedge block are connected an overlapping way, and the first wedge block and the second wedge block are made to slide relatively to extrude the workpiece to be fastened; the first wedge block is threadedly connectedwith a supported disassembly piece; the supported disassembly piece is supported on the second wedge block or a substrate and can be screwed down to drive the first wedge block and the second wedge block to slide relatively and loosen the first wedge block and the second wedge block from extrusion; the substrate or the second wedge block is threadedly connected with a fastening piece; and the fastening piece is connected with the first wedge block and is made to drive the first wedge block to move and extrude the second wedge block so that the workpiece to be fastened in the substrate. The fastening device can be used and installed conveniently and disassembled rapidly and can be adjusted in the extruding force.

Description

technical field [0001] The invention relates to a fastening device, in particular to a fastening device which is convenient for disassembly and installation. Background technique [0002] In the installation process of many parts, the method of squeezing the fastener is used to fix. This method adopts the wedge principle, that is, two wedges with inclined surfaces that can cooperate with each other are matched together to play a pressing role. This device is very easy to use and has good fastening performance, but when the fastened part is intended to be removed for maintenance, the squeezed and fastened wedge is difficult to loosen and difficult to disassemble. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fastening device that is easy to use, quick to disassemble and simple in structure, aiming at the problems existing in the prior art. [0004] The further technical problem to be solved by the present inv...
