Abstract
The invention provides a quick bolt pair which consists of a quick bolt of a hackle tooth and a quick nut with an elastic toothed bar. The nut can be quickly pressed down only by aligning the bolt with a nut hole and lightly pressing the bolt while in screwing down, and the bolt pair can be screwed down by rotating the minor angle of the bolt. The invention has simple structure, low cost, convenient use and wide application range.
Description
1, affiliated technical field
The present invention relates to a kind of quick bolt pair technology, specifically is exactly a kind of bolt pair that can tighten fast.
2, background technique
General bolt has v thread bolt, pipe thread bolt, trapezoidal thread bolt, square threaded form bolt, buttress thread bolt at present.These bolts differ from one another, but tightening of all must one when tightening enclosing, efficient is lower.Existing bolt patent is as: the quick screw of the patent No. 200720146596.1 and adopt the quick bolt assembly that is used to make up glued mould of the linkage structure and the patent No. 200520048055.6 of quick screw, complex structure, and Applicable scope is little.
3, summary of the invention
The purpose of this invention is to provide a kind of the deficiencies in the prior art that overcome, simple in structure, easy and simple to handle, the quick bolt pair of applied range.
4, description of drawings
Accompanying drawing 1 is the quick bolt pair erection drawing;
Accompanying drawing 2 is nut part figure;
Accompanying drawing 3 is bolt figure.
5, mode of execution
With reference to accompanying drawing to quick bolt pair of the present invention and should be used as following detailed description.
As shown in Figure 1, bolt 1, nut body 2, elasticity tooth bar 3, nut of the present invention is made up of nut body and the elasticity tooth bar more than a group, every group of elasticity tooth span is the multiple of lead of screw thread shown in accompanying drawing 1,2, elasticity tooth bar can be that parallel installation also can tilt to install better to cooperate with the bolt tooth a little on the same group, other shape of bolt pair is identical with plain bolt, can be fixed according to actual conditions.Shown in accompanying drawing 1 partial enlarged view A, the screw thread form of bolt 1 is a zigzag fashion, and the retaining direction is a working surface, working surface the tooth form oblique angle be about 3 °, can self-locking be as the criterion with screw thread.The direction of propulsion surface is the inoperative surface, and the tooth form oblique angle on inoperative surface is about 50 °, makes bolt advance smooth and easy being as the criterion.
The use step of quick bolt pair is as follows:
1, bolt 1 is aimed at nut bore and be pressed into, up to by till motionless;
2, when bolt by when motionless, again with instrument swivel bolts such as hand or spanners until tightening.
With quick bolt pair locking, use simply, clamp fast, applied widely, and also the bolt auxiliary structure is simple, and easily manufactured, with low cost, thereby, have good value for applications.
Claims (4)
1. quick bolt pair, form by bolt, nut, elasticity tooth bar, the group number of elasticity tooth bar is more than one group, the spacing of elasticity tooth bar is the multiple of lead of screw thread, parallel or the installation of tilting a little of elasticity tooth bar on the same group, it is characterized in that the bolt thread form is the notched teeth of several angle, the direction of propulsion surface gradient angle value of bolt thread is that the nut thread is made of elasticity tooth bar about 50 degree.
2. quick bolt pair according to claim 1, when being screwed into, bolt can be fast by advancing nut, and the Shi Zexu that back-outs rotation is back-outed.
3. according to claim 1,2 described quick bolt pairs, gradient is about 3 degree when the retaining direction surface of bolt thread, can self-locking after tightening.
4. according to claim 1,2 described quick bolt pairs, when it is used, earlier bolt is pressed into along nut bore, swivel bolt is tightened during to the position.
