Self-tightening flower basket bolt

Abstract

The invention provides a self-tightening flower basket bolt. The self-tightening flower basket bolt comprises a bolt body, a first pull rod and a second pull rod, wherein the bolt body is provided with a sleeve, and the first pull rod and the second pull rod are arranged at the two ends of the bolt body. Each pull rod comprises an adjustment rod and a connecting head, wherein each connecting headis located at the front end of the corresponding adjustment rod. The two ends of the bolt body are each provided with a threaded hole. Each adjustment rod penetrates the corresponding threaded hole and extends into the sleeve of the bolt body. The whole adjustment rod of the first pull rod is provided with a thread matched with the corresponding threaded hole. A baffle is arranged at the tail endof the adjustment rod of the second pull rod. An extending-and-contracting component is arranged between the end, close to the inner side of the second pull rod, of the sleeve and the baffle. The middle-rear segment of the adjustment rod of the second pull rod is provided with a locking thread matched with the corresponding threaded hole. The portion, between the locking thread and connecting headof the second pull rod, of the corresponding adjustment rod is a polish rod. When the locking thread is matched with the threaded hole in one end of the bolt body, the extending-and-contracting component is in the compressed state. According to the self-tightening flower basket bolt, the extending-and-contracting component is added on the basis of a common flower basket bolt; the self-tighteningfunction can be achieved; and safety of cargo and transportation tools is guaranteed.

Description

technical field [0001] The invention relates to the field of cargo transportation, in particular to a self-tightening turnbuckle bolt. Background technique [0002] Cargo transportation is usually tied with wire ropes or chains. During the transportation of the goods, due to the bumps or the characteristics of the goods themselves, the goods will become more and more tight, resulting in loosening of the wire rope or chain. After the wire rope or chain is loose, it loses the pre-tightening force on the cargo, directly threatening the safety of the cargo and the means of transportation. Turnbuckle bolts are usually used to pre-tighten the binding wire rope or chain, which itself does not have self-tightening function, so it needs to be checked and tightened regularly during transportation. If the turnbuckle is located on the top of the cargo, the inspection and tightening process itself is not only laborious, but also dangerous. [0003] Such as figure 1 As shown, the turn...
