Abstract

The utility model relates to a theftproof bolt which can avoid being disassembled, and a special sleeve thereof. For the theftproof bolt, the bolt head is made to be circular and has a certain taper so as to prevent a thief from unscrewing the bolt by all types of conventional wrenches; the end surface of the theftproof bolt is provided with a groove which can be driven by the special sleeve; the special sleeve comprises a connecting part and a sleeve head; the end surface of the sleeve head is provided with a raised line; and the outer outline of the raised line is anastomotic with the inner outline of the groove of the bolt head. The theftproof bolt has the benefits of being simple and practical in structure, easy in processing and low in cost, being capable of being reused, being hard to be disassembled without using the matched special sleeve and effectively holding back the theft act, and providing effective safety control for the outdoor communal facilities.

Description

A kind of conicity anti-theft bolt and the socket wrench specially adapted for it supporting with it
Technical field
The utility model relates to a kind of bolt, is meant a kind of conicity anti-theft bolt and supporting socket wrench specially adapted for it thereof especially.
Background technique
A lot of at present outdoor communal facilitys are often suffered to steal, usurp, destroy, for example electric power, communication, cable, street lamp facility etc.The object that these facilities do not use effective anti-theft measure or only use common outer-hexagonal bolt to be connected and fixed when installing, cause these facilities, equipment to be destroyed easily and to be stolen, and its complex structure of existing anti-theft bolt, production process is many, and cost is higher should not to be used on a large scale.
Summary of the invention
Stolen easily in order to overcome plain bolt, existing anti-theft bolt complex structure, the problem that cost of production is high, the utility model provides a kind of simple and practical conicity anti-theft bolt and supporting socket wrench specially adapted for it thereof.This anti-theft bolt can prevent the wrench dismounting with various routines effectively, is easy to stolen problem and simple in structure thereby solve with bolted object, can reuse again, promptly saves cost and reduces the wastage again.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of anti-theft bolt, comprise bolt head and have externally threaded screw rod, described bolt head outer side surface is made into the conicity shape, because of its without any force bearing point, instrument with routine can not block or vise bolt head, take off thereby bolt can not twisted, to be manufactured with the groove that can be driven by sleeve on the described bolt head end face, described groove be digital " 5 " font.
The matching used socket wrench specially adapted for it of a kind of and above-mentioned anti-theft bolt, comprise a joint and a tube head, described tube end surface is provided with a raised line, and the interior profile phase of the external frame of described raised line and the groove of bolt coincide, and a described tube raised line is numeral " 5 " word shape of reverse side.
The beneficial effects of the utility model are: structure tube list, be easy to processing, cost is low, can use separately, and also can be supporting and reusable with universal standard part nut or other anti-theft nut.Save cost and reduce the wastage, under the situation of not using this supporting socket wrench specially adapted for it, be difficult to dismantle this anti-theft bolt, can effectively check the theft destruction, for outdoor equipment provides effective safety guarantee.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings below.
The utility model has disclosed a kind of conicity anti-theft bolt, as shown in Figure 1 to Figure 3, bolt comprises bolt head 12 and has the screw rod 11 of outside thread 14, described bolt head 12 outer side surfaces are processed into the conicity shape, She Ji reason is can not block or vise bolt head with conventional instrument like this, takes off thereby can not twist bolt.Be processed with the groove 13 that can be driven by sleeve on described bolt head 12 end faces.Groove 13 described in the present embodiment is numeral " 5 " font, and with the supporting use of the sleeve of special use, the benefit of this design is to use common pliers or other non-special tools to turn bolt.
As shown in Figure 4, the utility model has also disclosed the matching used socket wrench specially adapted for it of a kind of and above-mentioned conicity anti-theft bolt, and sleeve is made of joint 21 and tube 22, and joint is set to positive hexagon, is conventional for convenience spanner being used sleeve.Described 22 end face is provided with a reverse side " 5 " font raised line 23, " 5 " font groove 13 of the external frame of described raised line 23 and bolt head 12 matches, the above-mentioned anti-theft bolt that is complementary can be tightened or unscrew to the sleeve of this special use, under the raised line 23 unmatched situations of the groove 13 of anti-theft bolt head 12 and sleeve tube 22, can't twist and take off this anti-theft bolt, play antitheft effect like this.When using this anti-theft bolt that fastening object is installed, this bolt can use separately, also can with universal standard nut or the supporting use of other anti-theft nuts.During fastening object, screw rod inserted to be connected and fixed in the hole at position, this socket wrench specially adapted for it tube 22 is inserted in the anti-theft bolt head grooves 13, entangle joint 21 with conventional wrench then, the key of anti-theft bolt is screwed in the object that will fix gets final product.During the dismounting anti-theft bolt, must use above-mentioned socket wrench specially adapted for it equally, could dismantle this anti-theft bolt, better play antitheft effect.
