Embodiment Construction

[0014] The technical scheme of the present invention will be further described below in conjunction with the accompanying drawings, but the required protection scope is not limited to the description;

[0015] Such as figure 1 , 2 As shown, the field anti-theft bolt provided by the present invention includes a screw rod 1 provided with a nut 5 on the top and a screw thread on the bottom. On the screw 1, a number of evenly arranged positioning holes 3 are opened on the edge of the positioning plate, and a shield 4 with an inner diameter larger than the nut 5 is also included. The bottom end of the shield 4 is fixed with a number of round head pins 6 that match the positioning holes 3 .

[0016] Because the bottom of the round head bolt 6 is a round end, its diameter is greater than the inner diameter of the positioning hole 3, in order to insert the round head bolt 6 and pass through the positioning hole 3, the bottom of the round head bolt 6 is provided with a part of the ro...

Abstract

The invention discloses an antitheft bolt used in the field. The antitheft bolt comprises a threaded rod. A nut is arranged on the top of the threaded rod, and a thread is arranged at the bottom of the threaded rod. A circular positioning plate is fixedly connected to the bottom end of the nut. The threaded rod is sleeved with the positioning plate. A plurality of evenly-distributed positioning holes are formed in the edge of the positioning plate. The antitheft bolt further comprises a protection cover with the inner diameter larger than that of the nut. A plurality of round-head plug pins matched with the positioning holes are fixedly connected with the bottom end of the protection cover. In the antitheft bolt, tight connection of the protection cover is achieved through the round-head plug pins and the positioning holes, the nut is protected, it is avoided that the nut is detached by lawbreakers after being exposed, and therefore the antitheft performance of the bolt is improved.

Description

technical field [0001] The invention relates to a bolt, in particular to an anti-theft bolt for field use. Background technique [0002] Bolt is a common fastener, which can be used for connection between mechanical parts and device fixing. Because the bolt and its matching nut have the advantages of easy installation and disassembly, they are currently widely used fasteners. But for the bolt and nut fasteners in the infrastructure in the wild, its safety is very important, such as the bolt and nut fasteners used in infrastructure such as railways, highway bridges, power transmission towers, and microwave communication towers. Since the bolts and nuts can be easily disassembled, they are often targeted by criminals for theft or destruction, making these infrastructures a great security risk. Contents of the invention [0003] The purpose of the present invention is to provide an anti-theft bolt for field use to solve the problems of easy disassembly and poor safety perfor...
