Abstract

The invention discloses an anti-theft carriage bolt for a bent variable-form wood structure. The anti-theft carriage bolt comprises a bolt body and an elastic rubber ring; the bolt body comprises a screw head, a rotation stopping neck section, a polished rod section and a screw section, the screw head, the rotation stopping neck section, the polished rod section and the screw section are sequentially connected from top to bottom, a plurality of oblique incisions are formed in one side of the screw section, and the slot width of the oblique incisions gradually decreases from top to bottom; theelastic rubber ring is fixed on a slot in the outer wall of the rotation stopping neck section in a surrounding mode; and the plurality of oblique incisions are arranged on one side of the screw section, and the screw section is bent and deformed towards one side with the oblique incisions by matching with knocking at a column body, so that the screw thread is damaged, and the bolt body, a secondconnecting piece and a nut are locked.

Description

【Technical field】 [0001] The invention relates to the technical field of carriage bolts, in particular to the technical field of anti-theft carriage bolts used in bent and deformed wooden structures. 【Background technique】 [0002] Carriage bolts were originally used for the combination of iron and wood on carriages. Because the head is a half-round head and there is a square neck under the head, it is also called half-round head square neck bolts or large half-round head square neck bolts. It is often used in wooden bolts. in structure. But existing carriage bolt does not have anti-theft function usually, if its fixed connector is stolen not only can cause property loss, also may cause potential safety hazard. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a kind of anti-theft carriage bolt for bending and deformed wooden structure, which can block the bolt body and the connecting parts by destr...
