Abstract

The invention relates to a bolt, and particularly relates to a novel fixing bolt for a hole. The novel fixing bolt for the hole comprises a pin bush and a pin needle, wherein the pin bush is a T-shaped hollow structure formed by a pin head and a pin rod; the pin needle is a cylinder, and the head of the cylinder is of a cone-shaped structure; at least a group of symmetrical limit holes are arranged at the tail end of the pin rod; the pin needle is sleeved and arranged in the pin bush; the length of the pin needle is less than that of the pin bush; a locknut is in bolt connection with the pin head; a spring is arranged between the locknut and the pin needle; and steel balls are coordinately arranged between the cone-shaped head of the pin needle and the limit holes. The novel fixing bolt for the hole provided by the invention has ingenious concept and simple structure; when the bolt is needed for limit, the locknut is only needed to be tightened, the spring supports the pin needle to move forwards; the cone-shaped structure at the head of the pin needle jacks up the steel balls to enter the limit holes, and the parts of the steel balls protruding from the limit holes can play the role in limiting; and when the bolt is needed to be taken out, the locknut is only needed to be loosened, the spring recovers from deformation, the pin needle draws back, and the steel balls between the pin needle and the limit holes are loosened from the limit holes for the bolt to be conveniently taken out.

Description

technical field

[0001] The invention relates to a plug, in particular to a novel fixed plug for holes. Background technique

[0002] The existing latch structure is very diverse, some are provided with a small hole at the end of the pin rod, and an iron wire is inserted in the small hole to play the role of the way the latch falls off; Prevent the latch from falling out. However, there is a common problem in the above methods, that is, the pin rod and the clamping parts are separated, which is very inconvenient to use, and the clamping parts are generally small and easy to lose, and special tools are required for installation, which is time-consuming and laborious , very inconvenient. Contents of the invention

[0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a technical solution for a new type of fixing pin for holes.

[0004] The new type of fixed pin for the hole includes a pin sleeve and a pin. The pin sleev...
