Abstract

The invention relates to a pin connection mechanism which is characterized by comprising a groove-shaped plate, a sliding pin, a round pin, a rotating mechanism, a baffle plate and a torsion spring, wherein a bottom plate of the groove-shaped plate is fixedly connected with the sliding pin; the sliding pin is slidably provided with the round pin in a sleeving way; a side plate of the groove-shaped plate is rotationally connected with the baffle plate through the rotating mechanism which is parallel to the sliding pin; the torsion spring is fixedly arranged on the rotating mechanism in a sleeving manner; and one end of the torsion spring is inserted into the side plate of the groove-shaped plate, and the other end of the torsion spring is arranged on the baffle plate so that the baffle plate is arranged on the round pin in a pressing way. The pin connection mechanism disclosed by the invention is suitable for an occasion in which frequent pin connection and pin connection elimination are required and can be used for effectively preventing the dropping, mistaken entrance and loss of the round pin.

Description

technical field

[0001] The invention relates to a connection mechanism, in particular to a pin connection mechanism which is suitable for frequent insertion and extraction and needs to stop the pin and prevent the loss of the pin after insertion and extraction. Background technique

[0002] Pin connection is a very convenient connection method, which is widely used in various fields, especially in railway wagons and vehicles. For example, when transporting the braces and braces in the concrete bridge support device, the braces and the braces are connected together by pinning when the vehicle loads the concrete bridge, and the pinning of the braces and the braces is released when the vehicle unloads the concrete bridge The upper strata lifting floor of double-deck transportation car special vehicle also is to coordinate the loading and unloading of automobile to carry out pin connection and unpin connection equally.

[0003] At present, the commonly used pin connection metho...
