Description
Technical field
The present invention relates to a kind of bolt, and in particular to a kind of fast lock fixed pattern anti-theft bolt.
Background technology
Bolt is a kind of common fastener, available between mechanical part connection and device fix, due to bolt and with
Its nut matched, which has, installs easy, the advantages of convenient disassembly, is currently widely used fastener.But for being in open country
Bolt and nut fastener in outer infrastructure, its security just seems critically important, such as railway, highway bridge, electric power pylon,
The bolt and nut fastener used in the infrastructure such as microwave communication tower.Because bolts and nuts can be disassembled easily,
Therefore, often by object of the criminal as theft or destruction so that these infrastructure have larger potential safety hazard.
The content of the invention
It is an object of the invention to：A kind of fast lock fixed pattern anti-theft bolt is provided, to solve conventional bolt for installing family
It is quick detachable present in outer infrastructure, 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, including top set threaded screw rod, the nut bottom provided with nut, bottom
End is connected with a circular location-plate, and location-plate is socketed on screw rod, and location-plate edge is provided with some positioning holes being evenly arranged, also
It is more than the shield of nut including an internal diameter, shield bottom is connected with some round end latches matched with positioning hole.
The round end latch bottom is provided with the groove that round end latch is divided into two.
The number of the positioning hole and round end latch is 3 or 6.
Polished rod minister's degree of the round end latch is identical with depth of positioning hole.
The beneficial effects of the invention are as follows：
Compared with prior art, the fast lock fixed pattern anti-theft bolt that the present invention is provided, in the affixed positioning in nut bottom
Some positioning holes are provided with plate, location-plate, shield is realized with positioning hole by round end latch and is closely connected, and protects nut, it is to avoid
Nut is dismantled after exposing by criminal, and then improves the theftproof performance of bolt.
Brief description of the drawings
Fig. 1 is the front view of the present invention；
Fig. 2 is the top view of the present invention；
In figure：1- screw rods, 2- location-plates, 3- positioning holes, 4- shields, 5- nuts, 6- round end latches.
Embodiment
Technical scheme is described further below in conjunction with accompanying drawing, but required protection domain does not limit to
In described；
As shown in Figure 1, 2, the fast lock fixed pattern anti-theft bolt that the present invention is provided, including top are provided with provided with nut 5, bottom
The screw rod 1 of screw thread, the bottom of nut 5 is connected with a circular location-plate 2, and location-plate 2 is socketed on screw rod 1, location-plate edge
Be provided with some positioning holes 3 being evenly arranged, in addition to an internal diameter is more than the shield 4 of nut 5, the bottom of shield 4 be connected with it is some with
The round end latch 6 that positioning hole 3 matches.
Because the bottom of round end latch 6 is blunt end, the internal diameter of positioning hole 3 is had a diameter larger than, for the ease of round end latch 6 is inserted
Enter and pass through positioning hole 3, the bottom of round end latch 6 is provided with the groove that round end latch 6 is divided into two.
In order to ensure steadiness that shield 4 is connected with location-plate 2, the number of the positioning hole 3 and round end latch 6 is 3
Or 6.
The polished rod minister degree of the round end latch 6 is identical with the depth of positioning hole 3, i.e., after round end latch 6 is connected with location-plate 2
It can not move up and down, further increase security.
Screw rod 1 is installed in place in use, first passing through nut 5, then shield 4 is enclosed on nut 5, rotating shroud 4 makes
Several round end latches 6 of its bottom align one by one with the positioning hole 3 opened up on location-plate 2, and then pushing protective cover 4 inserts round end
Pin 6, which inserts positioning hole 3, simultaneously finally makes the bottom of round end latch 6 be passed from the bottom of positioning hole 3, that is, completes the installation of bolt with consolidating
It is fixed, shield 4 can not easy removal, security and theftproof performance are improved.
