Abstract

The invention discloses a theftproof screw with a one-way bearing. The theftproof screw with the one-way bearing comprises a screw body, a screwing head, a first sleeve pipe, a second sleeve pipe, the one-way bearing and a connecting rod. The screwing head is fixed at the top of the screw body and the cross section of the screwing head is in a regular hexagon shape. A fixing hole is formed in the center of the top of the screwing head and internal threads are arranged in the fixing hole. The first sleeve pipe sleeves outside the screwing head and is in a cylinder shape. A vertical through hole, which is matched with the screwing head, is formed in the center of the first sleeve pipe. The one-way bearing is provided with an inner ring and an outer ring. The connecting rod penetrates the inner ring, and second external threads, which are matched with the internal threads, are arranged on the connecting rod. The second external threads are all located under the inner ring. The connecting rod is screwed in the fixing hole and a screwing groove is arranged on the connecting rod. The second sleeve pipe is fixed outside the outer ring and the cross section of the second sleeve pipe is in a regular hexagon shape with a hole in the middle. According to the screw, the one-way bearing is fixed on the screwing head, therefor the screw can be convenient to screw but difficult to unscrew, so that the theftproof objective can be achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, especially the technical field of screw rods. 【Background technique】 [0002] Screw is a commonly used fastener, which is widely used in various occasions that need to be connected. The general screw only has the function of fastening, and its disassembly is more convenient. For some outdoor facilities, some criminals will dismantle the screw to destroy the facility or check the specific structure in the facility, which is not conducive to the safety of the facility. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose an anti-theft screw rod with a one-way bearing, which can make the screw rod difficult to disassemble after installation, and has better anti-theft capability. [0004] In order to achieve the above object, the present invention proposes an anti-theft screw with one-way bearing, which includes a shaft, a...
