Abstract
Provided is a pin shaft locking mechanism. A limiting ring is arranged at the top end of a pin shaft, a fixing pin is sleeved with the limiting ring, and the fixing pin is supported through a fixing seat. According to the pin shaft locking mechanism, a matching type structure of the fixing pin and the limiting ring is used, the pin shaft can be mounted and demounted more easily compared with a previous mode, and cannot be damaged easily to fall off, and the pin shaft locking mechanism has the advantages of being strong in practicality, easy and convenient to operate and the like.
Description
Technical field
the utility model relates to vehicle body fittings field, specifically a kind of lock clasp mechanism.
Background technique
The bearing pin using on semitrailer, dumping car is more, often adopts cotter pin fixed pin shaft.At some key positions of vehicle, bearing pin is stressed larger, tends to occur that the cotter pin damage of bearing pin fixed end comes off, cause thus vehicle to occur security incident, to client, bring economic loss, cotter pin, pad etc. are outsourcing piece in addition, and buying and cost of transportation are all larger.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of simple lock clasp mechanism, to avoid the cotter pin that existing bearing pin occurs to damage the problem that causes vehicle safety accident.
The utility model solves its technical problem by the following technical solutions.
A lock clasp mechanism, is provided with position limit cycle on the top of bearing pin, suit one fixing pin in described position limit cycle, and described fixing pin supports by fixed base.
Described fixed base is U-shaped plate, and fixed base inner side is provided with spring, and described spring housing is contained on fixing pin, and the right-hand member of described fixing pin upper spring is provided with back-up ring.
Described back-up ring right side is provided with cushion.
A kind of lock clasp of the present utility model mechanism, is used the formula structure of fixing pin and position limit cycle, can make the installation and removal of bearing pin more simpler than mode in the past, and bearing pin is also difficult because damage comes off, and has the advantages such as practical, easy and simple to handle.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of bearing pin.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of lock clasp mechanism, is welded with position limit cycle 2 on the top of bearing pin 1, is inserted with fixing pin 5 in position limit cycle 2, and fixing pin 5 is through being welded on the U-shaped plate fixed base 4 on riser 3; Spring 6 is installed on fixing pin 5, and spring 6 is positioned at U-shaped fixed base 4 inner sides, and back-up ring 7 is installed on fixing pin 5, and back-up ring 7 is positioned at the right-hand member of spring 6; Cushion 8 is equipped with on back-up ring 7 right sides, after installing, unclamps bearing pin 1 fixing pin 5, fixing pin 5 is because the elasticity of spring 6 moves right locking bearing pin 1, impacting fixed base 4 when cushion 8 can effectively reduce fixing pin motion, have the effect of buffering, fixing pin 5 moves right under the elastic reaction of spring, and right-hand member inserts in the position limit cycle 2 on bearing pin 1, the locking of realization to bearing pin 1, disassembly-type only need to pull fixing pin 5 left and can unclamp bearing pin 1.
