Abstract
The utility model discloses a kind of coal machine coupling pin, comprise a column pin body, pin body cross-section shape is mated with coal machine coupling shape of through holes, and the length of pin body is greater than the degree of depth of coal machine coupling through hole; One end of pin body is provided with limited cap, and the other end longitudinally runs through a through hole, and the distance of lead to the hole site and limited cap equals the degree of depth of coal machine coupling through hole, also comprises the cotter pin that passes through hole.The beneficial effects of the utility model are, pin changes self into and fixes, and another side cotter pin is fixed, and without the need to using backplate, pin can change one by one, has saved the repair time, has brought convenience to maintenance.
Description
Technical field
The utility model relates to a kind of hardware & tools, especially a kind of coal machine coupling pin.
Background technique
Connect to come transmitting torque by needs by pin between coal machine coupling, the existing pin 5 for the connection of coal machine coupling is a simple cylinder, as shown in Figure 1, after through hole through two coupling 6, also backplate 7 to be installed at two ends to be fixed, such structure causes the handling of pin all extremely to bother, remove pin require great effort, take a lot of work, time-consuming, also existence is got pin and is easily hindered the hidden dangers such as hand.
Model utility content
The utility model object is, overcomes the defect of prior art, proposes a kind of coal machine coupling pin.
The technical solution adopted in the utility model is as follows:
A kind of coal machine coupling pin, comprise a column pin body, pin body cross-section shape is mated with coal machine coupling shape of through holes, and the length of pin body is greater than the degree of depth of coal machine coupling through hole; One end of pin body is provided with limited cap, and the other end longitudinally runs through a through hole, and the distance of lead to the hole site and limited cap equals the degree of depth of coal machine coupling through hole, also comprises the cotter pin that passes through hole.
The beneficial effects of the utility model are, pin changes self into and fixes, and another side cotter pin is fixed, and without the need to using backplate, pin can change one by one, has saved the repair time, has brought convenience to maintenance.
Accompanying drawing explanation
Fig. 1 is the connection diagram of existing pin.
Fig. 2 is the structural representation of the utility model pin.
Fig. 3 is the connection diagram of the utility model pin.
Embodiment
In order to more clearly state the utility model, below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figures 2 and 3, coal machine coupling pin, comprises a column pin body 1, and pin body cross-section shape is mated with coal machine coupling shape of through holes, and the length of pin body is greater than the degree of depth of coal machine coupling through hole; One end of pin body is provided with limited cap 2, and the other end longitudinally runs through a through hole 3, and the distance of lead to the hole site and limited cap equals the degree of depth of coal machine coupling through hole, also comprises the cotter pin 4 that passes through hole.During use, only need by pin body through coal machine coupling through hole, its one end is fixed by limited cap, and the other end is through after coal machine coupling through hole, then insertion opening pin realizes fixing.
Be only specific embodiment of the utility model above, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
