Abstract

The utility model discloses a ground surface anti-prying signboard requiring drilling and hammering a matched hammer-in expansion pin bush, in particular to a ground surface obstacle-free anti-pryingsignboard with the board surface capable of approximately keeping a level with the ground surface after drilled and hammered. The utility model comprises a hammer-in expansion ground surface anti-prying signboard body (1) required to be drilled and hammered and a hammer-in expansion cotter pin bush body (11) inserted and sleeved in a separate signboard body structure and the like, wherein a pin body peripheral wall top wall section (21), a pin body peripheral wall bottom wall section (22), a pin body inner hole (23), a pin body inner hole wall (24), a pin body inner and outer wall top surface(25), a pin body inner and outer wall bottom surface (26) and a plurality of longitudinal cotter pin split grooves (27) at the pin body inner and outer wall top wall section which are structurally combined are respectively arranged on the hammer-in expansion cotter pin bush body (11) inserted and sleeved in the signboard body. The utility model can be widely applied to be used for drilling and hammering ground surface signboards on the ground surface for all the urban underground water supply pipe networks and the like, and facilitates ground positioning for excavation and maintenance of underground facilities in the future, thereby having obvious social benefit.

Description

Want the anti-Sign Board of prizing and stealing of ground level of drill hammer dress hammering expansion distribution cover

Technical field

The utility model is that a kind of ground level that dress back board face and ground level can remain basically stable is accessible to be prevented prizing and stealing Sign Board through boring, and more particularly, it is a kind of ground level Sign Board.

Background technology

Because of lacking effective land marking for a long time on the avenue hard surface that gathers at the groundwater supply pipe network that extends in all direction, cable etc., thus to the excavation of these underground installations keep in repair, the Sun Huai De rotation of artificially constructing is kept away etc., and problem has been brought many inconvenience.

Summary of the invention

The purpose of this utility model is to adorn conveniently for overcoming deficiency of the prior art, provide a kind of simple in structure, boring, and the ground level that firmly practical the utility model wants drill hammer dress hammering expansion distribution to overlap prevents prizing and stealing the Sign Board technology.

The technical scheme that its technical matters that solves the utility model adopts is:

The utility model is wanted the anti-Sign Board of prizing and stealing of ground level of drill hammer dress hammering expansion distribution cover, comprise the anti-Sign Board board body 1 of prizing and stealing of the ground level of wanting the hammering of drill hammer dress to expand, plane 2, board body top, plane, board body top concave bar sign or convex line bar sign 3, board body top section excircle major diameter tapered wall 4, section excircle minor diameter tapered wall 5 at the bottom of the board body, board body endoporus 6, board body inner hole wall 7, board body endoporus top 8, the board body interpolation cover hammering inflation openings pin guide body 11 of wall wall bottom surface, board inside and outside 9 and other body structure overlaps the shank periphery wall wall section 21 that is respectively equipped with conjoined structure on the hammering inflation openings pin guide body 11 in board body interpolation, shank periphery wall diapire section 22, shank endoporus 23, shank inner hole wall 24, shank inside and outside wall end face 25, shank inside and outside wall bottom surface 26 and many longitudinal opening pins of shank inside and outside wall wall section ditch 27 that breaks.

The diameter of section excircle minor diameter tapered wall 5 is less than the diameter of shank endoporus 23 at the bottom of the described board body.The diameter of described board body top section excircle major diameter tapered wall 4 is greater than the diameter of shank endoporus 23.

The beneficial effects of the utility model are:

1, when with boring bar tools such as 220V electric current and portable circulation boring machines after boring the dress board hole of answering the degree of depth of pretending on the hard surface of avenue underground installation, again board body interpolation cover hammering inflation openings pin guide body 11 of the present utility model is inserted in the above-mentioned board hole, and up shank inside and outside wall end face 25, and then section excircle minor diameter tapered wall 5 at the bottom of the anti-board body of prizing and stealing Sign Board board body 1 of the ground level of wanting the hammering of drill hammer dress to expand is inserted many longitudinal opening pins of shank inside and outside wall wall section in the piece inlet holes break in the pipe of ditch 27, plane 2 is pushed up with hammering board bodies such as hammers in the back again, until plane, board body top 2 hammers are extremely remained basically stable with ground level, reach the people, the bus or train route face current accessible till, through hammering the shank periphery wall wall section 21 of pressing after being inflated expansion into shape the ground level of wanting the hammering of drill hammer dress to expand is prevented that prizing and stealing Sign Board board body 1 is firmly fixed in the board hole, thereby reached pick-proof and anti-theft, people from road surface, the car clog-free effect of passing through;

2, the utility model can be widely used in underground installation hard surfaces such as all avenue groundwater supply pipe networks, the cable board that makes a check mark is bored dress and uses, it can be for underground installation provides the ground positioning mark, and excavation maintenance, displacement and the intersection of new construction, the overlapping, rotation of underground installation are kept away etc. and to be provided convenience in the future for it;

3, the utility model is simple in structure, to bore dress convenient, firmly practical, can pick-proof, antitheft, and also people from road surface, car are current accessible, and its social benefit is obvious.
