Abstract
The utility model discloses anchor bolt, which comprises a screw nut, a push rod and an anchor bolt sleeve with a central through-hole. The anchor bolt sleeve is provided with an expansion part with a longitudinal opening and a connecting part connected with the screw nut. The push rod is equipped with a push rod joint which is close to the end of the screw nut; the cross section diameter of the push rod joint is larger than that of the central through-hole. The utility model has the advantages of simple structure and convenient operation and can avoid rigid and brittle plates such as glass and tile from being penetrated or crushed.
Description
Technical field
The utility model relates to a kind of crab-bolt, relates in particular to a kind of crab-bolt that is used for rigidity friable plate material anchorings such as glass, ceramic tile.
Background technique
At present, the crab-bolt in market is because the thickness unanimity of crab-bolt push rod, therefore when crab-bolt being hammered into rigidity friable plate material such as glass, ceramic tile, if it is firmly excessive, after causing the front end of crab-bolt push rod to stretch out the crab-bolt cover easily, go deep into sheet material and exceed designed depth, cause the sheet material fragmentation, bring unnecessary loss to the user.
The model utility content
Technical problem to be solved in the utility model is the defective that overcomes prior art, and a kind of rigidity friable plate material fragmentations such as glass, ceramic tile, convenient crab-bolt of using avoided is provided.
For solving the problems of the technologies described above, the utility model provides a kind of crab-bolt, comprise nut, push rod and have the crab-bolt cover of central through bore, described crab-bolt cover has the bulge and a joint that is connected with described nut that have longitudinal opening, described push rod is provided with push rod head near an end of described nut, and the diameter of this push rod head cross section is greater than the diameter of described central through bore.
Be provided with outside thread at described joint, in described nut, be provided with and the suitable internal thread of described outside thread.The diameter of the cross section of described push rod head is greater than the described cross-sectional diameter that has externally threaded joint.
Link position at described nut and push rod is provided with compression spring.
Owing to adopt technique scheme, the utlity model has following beneficial effect:
1, simple in structure;
2, can avoid rigidity friable plate material fragmentations such as glass, ceramic tile during binding;
3, easy to use.
Description of drawings
Fig. 1 is the STRUCTURE DECOMPOSITION schematic representation of the utility model crab-bolt.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-nut; The 2-push rod; 3-crab-bolt cover; The 4-bulge; The 5-joint; The 6-push rod head; The 7-outside thread; The 8-compression spring.
Embodiment
As shown in Figure 1, the utility model crab-bolt comprises nut 1, push rod 2 and has the crab-bolt cover 3 of central through bore, and push rod 2 can run through and stretches into central through bore, and crab-bolt cover 3 has a bulge 4 and a joint 5 that is connected with nut 1 that has longitudinal opening.Be provided with outside thread 7 in joint 5 outsides, in nut 1, be provided with the internal thread suitable with outside thread 7.Push rod 2 is provided with push rod head 6 near an end of nut 1, and the diameter of these push rod head 6 cross sections is greater than the diameter of the central through bore of crab-bolt cover 3.Preferably, the diameter of push rod head 6 cross sections is greater than the cross-sectional diameter of the joint 5 that has outside thread 7.Link position at nut 1 and push rod 2 also is provided with compression spring 8.
In use, one end of push rod 2 penetrates central through bore, under the effect of external force, stretch out from the bulge 4 of crab-bolt cover 3, and hammer in the rigidity friable plate materials such as glass, ceramic tile, in entering into the designed depth scope, push rod head 6 just in time withstands on the outer end of joint 5, stop push rod 2 to continue deeply, thereby avoid the fragmentation of rigidity friable plate materials such as glass, ceramic tile.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
