Abstract
The utility model relates to an expansion screw, which comprises a screw rod, a gasket, and an expansion sleeve, of which the tail part is split into a plurality of expansion pieces. The expansion screw is characterized in that a positioning head is also arranged. A screw hole which is matched with the screw rod is arranged on the positioning head. The outer wall of the positioning head is provided with a claw. A small part of the positioning head is inlaid into the expansion sleeve. The expansion screw has the advantages that objects can be connected and fixed conveniently, and the connection, the fixation, and the transportation of assembled objects are unable to be hindered.
Description
The utility model relates to a kind of connection, mounting article screw of being used for.
Existing setscrew mainly is made of screw rod, expansion sleeve, packing ring, nut, and the afterbody of expansion sleeve ftractures into several pieces intumescent sheets, and the afterbody of screw rod is taper.During use, on firm immovable point, bore earlier a hole that matches with setscrew, then setscrew is filled in the hole, tighten up nut, screw rod moves outside expansion sleeve under the effect of the tightening force of nut, and the intumescent sheet of expansion sleeve afterbody is perk outward under the compressing of taper screw rod tail, stings tight on the hole inwall on the immovable point, thereby screw rod is fixed on the immovable point, has made things convenient for article are fixed on the screw rod on the immovable point.Though this kind setscrew can be fixed on article on the firm immovable point easily, but because screw rod must stretch out one outward and cut greatly, intumescent sheet perk on the expansion sleeve is stung tightly in the hole, and the screw rod overslaugh of stretching out the carrying of the good assembled article of the installing of article and whole installing.
Goal of the invention of the present utility model is to provide a kind of and can easily article be connected, fixing, can not hinder that article connect, the setscrew of the carrying of fixing and assembled article.
The utility model is to realize like this, comprise that screw rod, packing ring, afterbody ftracture into the expansion sleeve of several pieces intumescent sheets, its specialization is also to be provided with a positioning head, and positioning head is provided with the screw that matches with screw rod, the outer wall of positioning head is provided with pawl, and the sub-fraction of positioning head is embedded in the expansion sleeve.
During work, earlier (the turn screw rod is filled in setscrew in the hole in, length one that match with setscrew as boring on wooden, the block rubber and the consistent hole of setscrew then at immovable point, positioning head moves outside the hole under the tightening up of screw rod, intumescent sheet on the expansion sleeve is avoided, the intumescent sheet perk is stung simultaneously tightly on hole wall,, intumescent sheet also is fixedly clamped positioning head, take out screw rod then,, thereby object is fixed on the immovable point precession screw rod again behind the required fixing object location.
Here, the effect of the pawl on the positioning head is to prevent that positioning head from spinning in the hole.
Positioning head is embedded in the expansion sleeve for convenience, and the end endoporus of expansion sleeve rear portion intumescent sheet is taper, and the end of the positioning head of corresponding taper intumescent sheet end endoporus also is taper.
The utility model compared with the prior art, owing to adopted positioning head, therefore, screw rod need not be pulled out positioning hole and just object can be fixed on the immovable point outward, make the utlity model has easily with article connect, fixing, can not hinder that article connect, the advantage of the carrying of fixing and assembled article.
Fig. 1 is a structural representation of the present utility model.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model mainly is made of expansion sleeve 4, the positioning head 5 that screw rod 1, packing ring 2, afterbody ftracture into several pieces intumescent sheets 3, positioning head 5 is provided with the screw 6 that matches with screw rod 1, the outer wall 7 of positioning head 5 is provided with pawl 8, the sub-fraction of positioning head 5 is embedded in the expansion sleeve 4, the end endoporus 9 of expansion sleeve 4 rear portion intumescent sheets 3 is taper, and the end 10 of the positioning head 5 of corresponding taper intumescent sheet end endoporus 9 also is taper.
Claims (2)
1, a kind of setscrew, comprise that screw rod, packing ring, afterbody ftracture into the expansion sleeve of several pieces intumescent sheets, it is characterized in that also being provided with a positioning head, positioning head is provided with the screw that matches with screw rod, the outer wall of positioning head is provided with pawl, and the sub-fraction of positioning head is embedded in the expansion sleeve.
2, setscrew according to claim 1 is characterized in that the end endoporus of expansion sleeve rear portion intumescent sheet is taper, and the end of the positioning head of corresponding taper intumescent sheet end endoporus also is taper.
