Embodiment Construction

[0020] Such as figure 1 , 2 As shown, the fast fastening bolt device of the present invention includes a bolt 2 , a nut 4 that can be tightened on the bolt 2 and a crimping head 1 for fastening the bolt 2 .

[0021] Wherein, the bolt 2 consists of a threaded screw rod 22 and a flat bolt head 21 connected with the screw rod 22, figure 2 The left and right sides of the middle bolt head 21 extending axially are roughly rectangular (see figure 1 Shown by the dotted line in the center), a bolt pin hole 21a extending perpendicular to the axis of the screw rod 22 is provided on it.

[0022] Such as figure 2 As shown, the crimping head 1 is composed of a crimping head connecting part 11 and a crimping head rod part 12, wherein the cross section of the crimping head connecting part 11 is an inverted U shape, and a crimping head pin hole 11a corresponding to the bolt pin hole 21a is provided on it, through which Insert the flat bolt head 21 into the connection part 11 of the inver...

Abstract

The invention discloses a bolt device being quickly fastened and disassembled, comprising a bolt (2), a nut and a bonding head (1); wherein the bolt is provided with a screw stem (22) and a bolt head (21) which are connected with each other; the nut can be screwed down on the screw stem (22); the bonding head (1) is connected with the bolt head (21) and can rotate correspondingly to the bolt head (21); the bonding head (1) includes a connecting part (11) of the bonding head and a rod part (12) of the bonding head, and the connecting part (11) of the bonding head is connected with the bolt head (21) by a pin (6). The bolt device can ensure components which are to be connected to be firmly pressed by using the bonding head, and can repeatedly realize rapid pressing, fixing and disassembling for large components without using other tools, so as to not only conveniently fix and disassemble the large components, but also ensure enough fastening force to prevent the components from being loose.

Description

technical field [0001] The invention relates to a device for fixing components or machine parts together or preventing relative movement between them, in particular to a bolt device capable of clamping and fixing large components and releasing them quickly. Background technique [0002] Traditional bolt connection devices usually include bolts and nuts tightened on the bolts. The assembly method is to pass the bolts through the components or parts to be connected, screw the nuts on the bolts, and then tighten the nuts with tools such as wrenches. On the bolts, therefore, the assembly and disassembly operations of such bolt connection devices are time-consuming and laborious, and the work efficiency is very low, so it is not suitable for the connection between equipment components that require installation and disassembly in a short time. [0003] In addition, the fastening force of the traditional bolt connection device is determined by the degree to which the worker tighten...
