Abstract
The invention belongs to the locking and fixing technology, and particularly relates to a tool-free quick demounting and mounting tightening screw used for quick fixing between two parts. Common expansion screws are generally disposable, work deformation is generated after use, and the situation is irreversible. A mounting body can be damaged when the screws are taken out. Fixing and locking are inconvenient in some places with thin, long and narrow space. Demounting needs to be carried out frequently, the efficiency of the adopted common screws is low, and locking cannot be achieved once a wrench is lacked. By means of the tool-free quick demounting and mounting tightening screw, tool-free mounting or demounting can be achieved very conveniently, mounting efficiency is greatly improved, and the embarrassing situation that mounting cannot be achieved due to lack of tools is eradicated.
Description
Technical field
The invention belongs to the technology of being locked, be specifically related to a kind of tool-free quick disassembly and assembly tensioner screw, for fixing fast between two component.
Background technique
Expanding is fixedly the very common a kind of fixing and locking device of modern society, and applicability widely, no matter be family expenses or commercial Application is all indispensable.Common swell fixture is generally disposable, can produce working deformation after using, irreversible.Bother very much when taking out, and damage can be caused to fixing body.In the elongated narrow and small place of some installing space, inconvenient fixing and locking.Also some needs often dismounting, between the component needing again larger power to fix, uses common screw efficiency comparison low, has lacked spanner and just cannot lock.
Summary of the invention
Technical problem to be solved by this invention is: tensioner screw has use widely, and general tensioner screw is all disposable, will produce working deformation after using, and is inconvenient to the feature of taking out.By using tool-free quick disassembly and assembly tensioner screw, the installation or removal without the need to instrument can being realized very easily, significantly improve installation efficiency, stopping the difficult situation cannot installed because lacking instrument.
Technological scheme of the present invention is: a kind of tool-free quick disassembly and assembly tensioner screw, and this tensioner screw is by stretching screw, tightening nut, sleeve, pin and handle, and wherein said stretching screw to be arranged in sleeve and at one end to have pin-and-hole; Described tightening nut is threaded with described stretching screw, and outer surface is truncated cone shape; Described sleeve at one end has annular boss, circumferentially has some axial grooves in the other end tensioner part; Described handle is connected with stretching screw by pin, and the outer mold surface of this handle forms cam, coordinates with the annular boss of sleeve.
The tightening part of described sleeve is exceptionally threaded on surface, inner surface belt taper hole.
Rotate stretching screw by handle during installation, thus regulate the position of tightening nut.
Quick mounting is completed by pull-up handle during installation.
The invention has the beneficial effects as follows: easy to use, can directly install without the need to instrument.This invention can use easily on the hole of various hard material, and the hole diameter scope be suitable for is comparatively large, and the hole type be suitable for is also many.This invention is used for narrow space, or needs the place of often dismounting, can increase substantially dismounting speed, and remove the puzzlement lacking instrument from, enable installation more efficient and convenient, and can not increase the part that leaks outside during working state.If use common locking nut in the place of narrow space, one is that spanner is inconvenient to stretch into, and two are that the time of retaining screw is long.Manually the time of tightening is approximately 1 point of half to normal screws, only needs 10s, significantly improve the efficiency of installation with the time that the present invention is locked.

Embodiment
A kind of tool-free quick disassembly and assembly tensioner screw, this tensioner screw is by stretching screw 1, tightening nut 2, sleeve 3, pin 4 and handle 5, and wherein said stretching screw 1 to be arranged in sleeve 3 and at one end to have pin-and-hole; Described tightening nut 2 is threaded with described stretching screw 1, and outer surface is truncated cone shape; Described sleeve 3 at one end has annular boss, circumferentially has some axial grooves in the other end tensioner part; Described handle 5 is connected with stretching screw 1 by pin 4, and the outer mold surface of this handle 5 forms cam, coordinates with the annular boss of sleeve 3.
The tightening part of described sleeve 3 is exceptionally threaded on surface, inner surface belt taper hole.
Rotate stretching screw 1 by handle 5 during installation, thus regulate the position of tightening nut 2.
Quick mounting is completed by pull-up handle 5 during installation.
Using method of the present invention is: tool-free quick disassembly and assembly tensioner screw is advanced in the hole needing to install; Rotatory handling 5, adjusts to the power of needs by stretching screw 1 and the tightening force of tightening nut 2; Break tight handle 5.
