Embodiment Construction

[0020] refer to figure 1 , a locking joint proposed by the present invention includes: bolts, nuts 1 , cylinders 2 and plunger rods 3 .

[0021] The bolt is composed of a fixedly connected screw 4 and a head 5. Inside the screw 4, there is a first cylindrical cavity 4-1. The first cylindrical cavity 4-1 runs through the end surface of the screw 4 away from the head. The insertion rod 3 is installed on the first cylindrical cavity. The cavity 4-1 is located on the central axis of the first cylindrical cavity 4-1. The central axis of the first cylindrical chamber 4 - 1 coincides with the central axis of the screw 4 .

[0022] The nut 1 is threadedly connected with the screw rod 4, the cylinder 2 is installed in the threaded hole 1-1 of the nut 1, and the central axis of the cylinder 2 coincides with the central axis of the threaded hole 1-1. The outer diameter of the cylinder 2 is smaller than or equal to the inner diameter of the first cylindrical cavity 4 - 1 , and the circu...

Abstract

The invention provides a locking connecting part. The locking connecting part comprises a bolt, a nut, a cylindrical tube and an insertion bar. The bolt is composed of a screw rod and a head which arefixedly connected. The screw rod is internally provided with a first cylindrical cavity. The first cylindrical cavity penetrates through the end face, far away from the head, of the screw rod. The insertion bar is mounted in the first cylindrical cavity and located on the central axis of the first cylindrical cavity. The central axis of the first cylindrical cavity coincides with the central axisof the screw rod. According to the locking connecting part, through cooperation of a short bar on the insertion bar located in the screw rod and a groove in the inner wall of the cylindrical tube inthe nut, the effect of preventing g the nut from getting loosened from the screw rod is achieved after the nut and the screw rod are screwed through threads. Moreover, the nut and the screw rod are connected through the normal thread structure, and application of the locking connecting part in any environment applicable to bolts can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of production and processing of forklift accessories, in particular to a locking connector. Background technique [0002] Bolts are a commonly used accessory for forklifts and are used to connect workpieces that need to be assembled together. However, under the influence of long-term vibration or rotation or shaking, the existing bolts are likely to cause receding phenomenon and loose connection, which needs to be improved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a locking connector. [0004] A deadbolt connector proposed by the present invention includes: a bolt, a nut, a cylinder and a plunger; [0005] The bolt is composed of a fixedly connected screw and a head. There is a first cylindrical cavity inside the screw. The first cylindrical cavity runs through the end surface of the screw away from t...
