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:
The present invention relates to a kind of fastening piece, specifically be meant a kind of quick fastening bolt card that is used for clamping fast fastening body and function way.
Background technique:
Existing clamping bolt generally all is made up of the screw rod nut; When carrying out fastening operation; To fix nut with spanner earlier; And then clamp bolt head with spanner bolt is screwed in the nut, perhaps to fix bolt shank with spanner earlier, and then clamp nut with spanner and nut is spun on the bolt shank gives fastening clamped.Also just say that when carrying out fastening operation, two hands will be operated simultaneously, the proficiency fixing bolt, the nut of screwing on the other hand, very inconvenient.When running into clamped thing and being large piece, a people accomplishes fastening operation very much, must want two people to operate simultaneously and could accomplish fastening task.As; The amalgamation assembling of ground satellite paraboloidal antenna is carried out clamp operation simultaneously with regard to two people of needs; The front of one people satellite paraboloidal antenna on ground is clamped screw head with spanner and is stoped nut to drive the bolt rotation; Another people nut that screws up with a wrench at the back side of satellite paraboloidal antenna is assembled amalgamation, and it is time-consuming very to require great effort, and working efficiency is low.Therefore, existing technology exists effort time-consuming, the problems and shortcomings of inefficiency.
Summary of the invention:
Problems and shortcomings to above-mentioned existing technology existence; The present invention adopts by the tightening latch that is provided with angle groove, bolt head and is provided with the technological scheme of the eccentric pintle hook lock and the bolt card that is fixedly clamped that elastic washer is formed of eccentric shaft, cam; A kind of quick fastening bolt card is provided; Be intended to realize being fixed the connection fastener fast, make the amalgamation assembling of ground satellite paraboloidal antenna reach time saving and energy saving, the purpose of simple and effective through the squeezing action of utilizing eccentric wheel to rotate.
The objective of the invention is to realize like this: a kind of quick fastening bolt card; Comprise tightening latch, elastic washer, eccentric pintle hook lock; Wherein: described tightening latch is a step circle cylindricality aluminium alloy element; The lower end of tightening latch is provided with the bolt head of flange step, and a side of tightening latch upper end cylinder is provided with the angle groove of the gap formation that tilts from bottom to top;
Described elastic washer is the plastic spacer of ring;
Described eccentric pintle hook lock is a doorframe shape aluminium alloy element; That two doorframe suspension column place symmetries of eccentric pintle hook lock are fixed with is columniform, with the tangent cam of a side of doorframe suspension column; Be connected with an eccentric eccentric shaft that is provided with between two cams, the doorframe crossbeam of eccentric pintle hook lock is called and sticks up handle;
Use annexation
During application the upper end of tightening latch passed the preset hole of two slit bamboo or chopped wood fasteners; Pad is gone up elastic washer again; The eccentric shaft of eccentric pintle hook lock is snapped in the angle groove of tightening latch one side, is manual another side that handle goes to tightening latch that sticks up of stirring eccentric pintle hook lock in the center of circle with the axle center of eccentric shaft; At this moment, the bolt head of the cam of eccentric pintle hook lock and tightening latch is fixed two slit bamboo or chopped wood fasteners jointly and links together.
Working principle
The eccentric shaft of eccentric pintle hook lock makes cam constitute eccentric cam, and the squeezing action of utilizing eccentric wheel to rotate realizes being fixed the purpose that connects fastener.
Above-mentioned; The present invention adopts by the tightening latch that is provided with angle groove, bolt head and is provided with the technological scheme of the eccentric pintle hook lock and the bolt card that is fixedly clamped that elastic washer is formed of eccentric shaft, cam; Having overcome the connection of existing technology bolt exists effort time-consuming; The problems and shortcomings of inefficiency, a kind of quick fastening bolt card that is provided realizes being fixed fast the connection fastener through the squeezing action of utilizing eccentric wheel to rotate; Make the amalgamation assembling of ground satellite paraboloidal antenna reach time saving and energy saving, the purpose of simple and effective.
Description of drawings:
Fig. 1 is the structural representation of a kind of quick fastening bolt card of the present invention;
Fig. 2 is the application state reference view of a kind of quick fastening bolt card of the present invention;
Fig. 3 is that each disassembled axle of a kind of quick fastening bolt card of the present invention is surveyed schematic representation.
Embodiment below in conjunction with in the accompanying drawing does further explain to the present invention, but should not be construed as any restriction of the present invention.
Among the figure: tightening latch 1, angle groove 11, bolt head 12, elastic washer 2, eccentric pintle hook lock 3, eccentric shaft 31, stick up handle 32, cam 33, fastener 01.
Embodiment:
Consult Fig. 1～Fig. 3; A kind of quick fastening bolt card of the present invention; Comprise tightening latch 1, elastic washer 2, eccentric pintle hook lock 3; Wherein: described tightening latch 1 is a step circle cylindricality aluminium alloy element, and the lower end of tightening latch 1 is provided with the bolt head 12 of flange step, and a side of tightening latch 1 upper end cylinder is provided with the angle groove 11 of the gap formation that tilts from bottom to top;
Described elastic washer 2 is the plastic spacer of ring;
Described eccentric pintle hook lock 3 is a doorframe shape aluminium alloy element; That two doorframe suspension column place symmetries of eccentric pintle hook lock 3 are fixed with is columniform, with the tangent cam 33 of a side of doorframe suspension column; Be connected with an eccentric eccentric shaft 31 that is provided with between two cams, the doorframe crossbeam of eccentric pintle hook lock 3 is called and sticks up handle 32;
Use annexation
During application the upper end of tightening latch 1 passed the preset hole of two slit bamboo or chopped wood fasteners 01; Pad is gone up elastic washer 2 again; The eccentric shaft 31 of eccentric pintle hook lock 3 is snapped in the angle groove 11 of tightening latch 1 one sides, is manual another side that handle 32 goes to tightening latch 1 that sticks up of stirring eccentric pintle hook lock 3 in the center of circle with the axle center of eccentric shaft 31; At this moment, the bolt head 12 of the cam 33 of eccentric pintle hook lock 3 and tightening latch 1 is fixed two slit bamboo or chopped wood fasteners 01 jointly and links together.
Working principle
