Abstract
The utility model relates to a tightening bolt, in particular to a tightening bolt used for the hollow wall. The utility model is composed of an across lock block, a screw and a thimble. The thimble is arranged on the screw, and one end of the screw is connected with the across lock block which can right-left rotated through the pin of the across lock block while another end is provided with a nut. A flat mat and a spring mat are arranged on one side of the nut which is suitable for the screw. The utility model aims at providing a bolt which can used for tightening the moderate loading objects in the wall which is built with air bricks. The across lock block which can right-left rotated is arranged on the bolt and put the bolt into the beat hole, press the plastic thimble in order to make the across lock block sidelong, lock the screw so that tighten the objects.
Description
Technical field:
The utility model relates to a kind of clamping bolt, particularly a kind of clamping bolt that is used for hollow wall.
Background technique:
At present, hollow brick is as a kind of environmental protection, energy-saving building material and be widely applied, and the body of wall major part of building is a hollow brick wall, and the EXPANSION ANCHOR BOLTS that in the past is used for the solid brick body of wall has not been suitable for hollow brick wall, not only fastening strength is not enough, but also hollow brick is pulverized.
Summary of the invention:
The purpose of this utility model is to provide a kind of bolt that is used for tightening at hollow brick wall moderate load object.But be with the cross locking piece of left-right rotation on this bolt, bolt is put into the hole of accomplishing fluently, the extruding plastic sleeve pipe makes the cross locking piece cross, and blocks screw rod, and object is fastening.
The purpose of this utility model is achieved through the following technical solutions:
The hollow wall clamping bolt is made up of cross locking piece, screw rod, sleeve pipe.Casing pipe sleeve on screw rod, but an end of screw rod be connected with the cross locking piece of left-right rotation by cross locking piece pin, the other end of screw rod is furnished with nut.Also be furnished with plain cushion, spring pad with nut one end that screw rod matches.
Advantage of the present utility model and good effect are:
The utility model is simple in structure, easy for installation, and stress that can dispersion hole increases fastening strength, prevents that hollow brick from pulverizing.
Description of drawings:
Fig. 1 is the utility model working state schematic representation;
Fig. 2 is the left view of Fig. 1.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings, at an end of screw rod (3), cross locking piece (1) is hinge-like with screw rod (3) through cross locking piece pin (2).Cross locking piece (1) is pressed into semicircle shape or groove shape with tinsel, is buckled on the cylindrical of screw rod (3).Cross locking piece (1) leans against the outside of screw rod (3) when bolt is not worked.When needing to use, on hollow brick wall, punch earlier, after the hole is accomplished fluently, bolt is stretched in the hole with drill hammer.Rotary screw (3) then, nut (7) is pushed sleeve pipe (4) by spring pad (6), plain cushion (5), and the sleeve pipe that is extruded (4) rotates the cross locking piece (1) that leans against on the screw rod (3) and crosses, and blocks screw rod (3), prevent that bolt from falling in the hollow brick, object is fastening.Because the extruding of nut (7) and cross locking piece (1), sleeve pipe (4) expands in the hole, and the stress of dispersion hole has increased fastening strength, prevents the hollow brick pulverizing again.
Cross locking piece of the present utility model (1) can pass through iron plate punching press, bending, make after zinc-plated.Sleeve pipe (4) but injection moulding make.
The material of sleeve pipe of the present utility model (4) can be selected metal, plastics for use, and sleeve pipe also can have groove on (4), expands in the hole, and object is fastening.
Claims (2)
1. hollow wall clamping bolt, form by cross locking piece, screw rod, sleeve pipe, it is characterized in that: sleeve pipe (4) is enclosed within on the screw rod (3), an end of screw rod (3) by cross locking piece pin (2) but be connected with the cross locking piece (1) of left-right rotation, the other end of screw rod (3) is furnished with nut (7).
2. hollow wall clamping bolt as claimed in claim 1 is characterized in that: also be furnished with plain cushion (5), spring pad (6) with nut one end that screw rod (3) matches.
