Abstract
The invention discloses a quick-lock antitheft bolt. The quick-lock antitheft bolt comprises a screw with a screw cap on top and threads on bottom, wherein the bottom end of the screw cap is fixedly connected with a circular positioning plate, the positioning plate is connected to the screw in a sleeving manner, a plurality of positioning holes which are uniformly distributed are formed in the edge of the positioning plate, and the quick-lock antitheft bolt also comprises a protection cover with an inner diameter greater than the screw cap, and the bottom end of the protection cover is fixedly connected with a plurality of round-head safety pins matched with the positioning holes. The protection cover protects the screw cap by means of the tight connection of the round-head safety pins and the positioning holes, so that the screw cap, after being exposed, can be prevented from being disassembled by a lawbreaker, and the antitheft performance of the bolt is further improved.
Description
Technical field
The present invention relates to a kind of bolt, be specifically related to a kind of fast lock fixed pattern anti-theft bolt.
Background technique
Bolt is a kind of common fastening piece, can be used for connecting between mechanical part and device is fixed, and installing easily because bolt and the nut that mates with it have, the advantages such as convenient disassembly, is the fastening piece of extensively employing at present.But for the bolt and nut fastening piece be in the Infrastructure in field, its Security just seems very important, as the bolt and nut fastening piece used in the Infrastructure such as railway, highway bridge, electric power pylon, microwave communication tower.Because bolts and nuts can disassemble easily, therefore, often by lawless person as theft or the object that destroys, make these Infrastructure there is larger potential safety hazard.
Summary of the invention
The object of the invention is to: a kind of fast lock fixed pattern anti-theft bolt is provided, to solve quick detachable for existing for mounted outdoor Infrastructure of conventional bolt, the problems such as poor safety performance.
The present invention is achieved by the following technical solution:
A kind of fast lock fixed pattern anti-theft bolt, comprise that top is provided with nut, threaded screw rod is established in bottom, described nut bottom is connected with a circular positioning plate, positioning plate is socketed on screw rod, positioning plate edge has some positioning holes be evenly arranged, also comprise the guard shield that an internal diameter is greater than nut, guard shield bottom is connected with some round end latches matched with positioning hole.
The groove be divided into two by round end latch is had bottom described round end latch.
The number of described positioning hole and round end latch is 3 or 6.
The polished rod minister degree of described round end latch is identical with depth of positioning hole.
The invention has the beneficial effects as follows:
Compared with prior art; fast lock fixed pattern anti-theft bolt provided by the invention; an affixed positioning plate bottom nut; positioning plate has some positioning holes; guard shield realizes compact siro spinning technology by round end latch and positioning hole; protection nut, avoids nut to expose and to be dismantled by lawless person afterwards, and then improve the theftproof performance of bolt.
Accompanying drawing explanation
Fig. 1 is plan view of the present invention;
Fig. 2 is plan view of the present invention;
In figure: 1-screw rod, 2-positioning plate, 3-positioning hole, 4-guard shield, 5-nut, 6-round end latch.
Embodiment
Below in conjunction with accompanying drawing, technological scheme of the present invention is described further, but described in required protection domain is not limited to;
As shown in Figure 1, 2, fast lock fixed pattern anti-theft bolt provided by the invention, comprise that top is provided with nut 5, threaded screw rod 1 is established in bottom, described nut 5 bottom is connected with a circular positioning plate 2, positioning plate 2 is socketed on screw rod 1, positioning plate edge has some positioning holes 3 be evenly arranged, and also comprises the guard shield 4 that an internal diameter is greater than nut 5, and guard shield 4 bottom is connected with some round end latches 6 matched with positioning hole 3.
Owing to being blunt end bottom round end latch 6, its diameter is greater than positioning hole 3 internal diameter, for the ease of round end latch 6 is inserted through positioning hole 3, has the groove be divided into two by round end latch 6 bottom described round end latch 6.
In order to ensure the steadiness that guard shield 4 is connected with positioning plate 2, described positioning hole 3 is 3 or 6 with the number of round end latch 6.
The polished rod minister degree of described round end latch 6 is identical with positioning hole 3 degree of depth, and namely round end latch 6 cannot move up and down after being connected with positioning plate 2, further increases Security.
During use, first by nut 5, screw rod 1 is in place, then guard shield 4 is enclosed within nut 5, rotating shroud 4 makes several round end latches 6 bottom it align one by one with the positioning hole 3 that positioning plate 2 is offered, then pushing protective cover 4 makes round end latch 6 insert positioning hole 3 and finally make round end latch 6 bottom pass from positioning hole 3 bottom, namely the installation completing bolt is with fixing, and guard shield 4 cannot easy removal, and Security and theftproof performance are improved.
