A but recycle's inflation screw, its is rational in infrastructure, can use repeatedly, loading and unloading are convenient, improve work efficiency.
Description
Technical field
The utility model relates to setscrew field, especially a kind of recyclable setscrew recycled.
Background technique
Setscrew in general be metallic expansive screw, setscrew is is fixedly utilize wedge shape gradient to impel expand produce friction bond stress, reach fixed effect.One, screw is screw thread, and one has tapering.Outer bread one iron sheet (having plenty of steel pipe), iron sheet cylinder (steel pipe) half has some otch, they are filled in hole that wall is accomplished fluently together, then split nut, nut pulls outward screw, tapering is drawn in iron sheet cylinder, and iron sheet cylinder is by spreading, so tightly fixing on the wall, be generally used for fastening on the material such as cement, brick such as protective grating, canopy, air-conditioning.But general setscrew is difficult to dismounting after installing or needs destructive dismounting, can not dismantle recycling with the setscrew crossed, waste material.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome above-mentioned middle Problems existing, and provide a kind of recyclable setscrew recycled, it is rational in infrastructure, can Reusability, easy to loading and unloading, increases work efficiency.
The utility model solves the technological scheme that its technical problem adopts: a kind of recyclable setscrew recycled, comprise rotary tack that fixing nail and fixing nail spin mutually, be enclosed within cross section between fixing nail and rotary tack have trapezium structure some expansion sleeves, be arranged on clamping slide rail between fixing nail and expansion sleeve and Compress Spring, described fixing nail and rotary tack side have the taper slide guide face mutually adaptive with the inclined-plane of expansion sleeve respectively, and described fixing nail top is provided with stud; Described rotary tack bottom is provided with the adaptive screw that mutually to spin with stud;
Described clamping slide rail comprises the countersunk head projection seat on the inclined-plane, downside being arranged on expansion sleeve, and is arranged on the countersunk head concave slide groove in fixing nail slide guide face; Described countersunk head concave slide groove and countersunk head projection seat are clampings of mutually sliding;
The two ends of described Compress Spring be fixedly installed on expansion sleeve respectively roof face, side and stud on; Described stud is also provided with the limit dais being positioned at Compress Spring top.
As preferred scheme, bottom described screw, chamber is reserved in the displacement had for accommodating stud.
As preferred scheme, described Compress Spring has the inclination angle of oblique downside.
As preferred scheme, described expansion sleeve is four.
The beneficial effects of the utility model are: a kind of recyclable setscrew recycled, expansion sleeve is pressed down by rotary tack, expansion sleeve, at the upper and lower slip expander in fixing nail slide guide face, fixes in hole, unclamps rotary tack, expansion sleeve is under Compress Spring effect, expansion sleeve retracted for clearance, takes out setscrew, can return Reusability, easy to loading and unloading, increase work efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is a kind of recyclable setscrew overall structure schematic diagram recycled described in the utility model;
Fig. 2 is a kind of recyclable setscrew lateral cross section structural representation recycled described in the utility model.
Accompanying drawing acceptance of the bid note is described below: 1, fixing nail, and 11, stud, 12, countersunk head concave slide groove, 2, rotary tack, 21, screw, 22, displacement reserves chamber, 3, expansion sleeve, 31, countersunk head projection seat, 4, Compress Spring.
