Problems solved by technology

For example, the assembly and assembly of the ground satellite parabolic antenna requires two people to perform the clamping operation at the same time. One person clamps the screw head with a wrench on the front of the ground satellite parabolic antenna to prevent the nut from driving the bolt to rotate, and the other uses a wrench on the back of the satellite parabolic antenna. Tightening the nuts for assembly and assembly is very laborious and time-consuming, and the work efficiency is low
Therefore, existing technology is laborious and time-consuming, the problem and deficiency of inefficiency

Embodiment Construction

[0017] refer to Figure 1 ~ Figure 3 , a fast fastening bolt of the present invention, including a bolt rod 1, an elastic washer 2, and an eccentric lock clip 3, wherein: the bolt rod 1 is a stepped cylindrical aluminum alloy member, and the lower end of the bolt rod 1 is provided with a convex The bolt head 12 of the edge step, one side of the cylinder at the upper end of the bolt rod 1 is provided with a slanted slot 11 consisting of a bottom-up slope;

[0018] The elastic washer 2 is an annular plastic gasket;

[0019] The eccentric lock card 3 is a door frame-shaped aluminum alloy component, and the two door frame pillars of the eccentric lock card 3 are symmetrically fixed with a cylindrical cam 33 that is tangent to one side of the door frame pillar. An eccentric shaft 31 arranged eccentrically is connected between them, and the door frame crossbeam of the eccentric locking card 3 is called a handle 32;

Abstract

The invention discloses a quick tightening clamp, which comprises a tightening latch (1), an elastic washer (2) and an eccentric locking clamp (3). A technical scheme that the tightening latch provided with a bevel groove and a tightening head, the eccentric locking clamp provided with an eccentric shaft and a cam, and the elastic washer form the clamping and fixing tightening clamp is adopted, and overcomes the defects of high labor and time consumption and low efficiency of bolt connection in the prior art. The provided quick tightening clamp quickly presses and fixedly connects a workpiece to be tightened through the extruding action generated when an eccentric wheel rotates, so that the aims of time and labor conservation, simplicity, convenience and high efficiency are fulfilled when a ground satellite parabolic antenna is assembled.

Description

Technical field: [0001] The invention relates to a fastener, in particular to a fast fastening bolt used for quickly clamping and connecting objects. Background technique: [0002] Existing fastening bolts are generally composed of screw nuts. When performing fastening operations, the nuts must be fixed with a wrench, and then the bolt heads are clamped with a wrench to screw the bolts into the nuts. Use a wrench to fix the bolt rod, and then use a wrench to clamp the nut and screw the nut on the bolt rod to tighten the clamped parts. That is to say, when carrying out fastening operation, two hands will operate simultaneously, one hand fixes the bolt, and the other hand tightens the nut, which is very inconvenient. When the object to be clamped is a large piece, it is very difficult for one person to complete the fastening operation, and two people must operate at the same time to complete the fastening task. For example, the assembly and assembly of the ground satellite p...
