Abstract
The utility model discloses a pin which comprises a pin cap (1) and a pin rod (2), wherein a wedge-shaped through hole (3) is formed at the tail end of the pin rod (2). When in use, a wedge-shaped clamping pin is inserted from the end of the wedge-shaped through hole (3) with large aperture, and tightly clings to the inner surface of the wedge-shaped through hole (3), and the contact surface is large. The pin has simple manufacture, little possibility of breaking and dropping in use and convenient assembly and disassembly.
Description
Technical field
The utility model relates to a kind of link, is specifically related to a kind of pin.
Background technique
In technology utilization fields such as boats and ships, Motor Vehicle manufacturing, use pin through regular meeting.Common pin generally all is to use in conjunction with cotter pin, just blocks by cotter pin and can not drop out in machine making a call to an aperture on the pin, can not run.But the environment under shed pin at some abominable (strong as shaking) is easy to fracture, cause pin to come off and can not act on the machine, lead to especially big production safety accident, and the pin of prior art is not quick detachable, as improvement, notice of authorization number is in the Chinese patent " a kind of pin " of CN2474779Y, the pin rod end of mentioning at pin is provided with a long strip through hole, during use trapezoidal fastener is inserted in the long strip through hole, this device is convenient to dismounting, but after inserting trapezoidal fastener in the rectangular through hole, because the aperture of long strip through hole is of a size, make that trapezoidal fastener and the through-hole wall surface of contact of not fitting is little, so fastener being easy to slide and coming off under the strong environment of vibrations, when if the straight shape fastener that uses aperture and through hole to match inserts, take out again inconvenient.
The model utility content
The technical problems to be solved in the utility model is the above-mentioned deficiency at prior art, provides a kind of the vibrations to be difficult under the strong environment breaking away from, rupturing and remove and install pin easily.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of pin, comprise pin rod and pin cap, and described pin rod end is provided with a wedge shape through hole.
In order to adapt to different Environmental Conditions, the pin rod of above-mentioned pin can be for cylindrical or square.
For safety is firm more, above-mentioned wedge shape through hole crosses the axis of pin rod.
The beneficial effects of the utility model are:
1. the utility model adopts and establishes a wedge shape through hole at the pin rod end of pin, because aperture one end of wedge shape through hole is big, one end is little, the wedge shape bayonet lock that matches when shape and wedge shape through hole from the large aperture end of wedge shape through hole insert the back and wedge shape through-hole wall surface of contact big, more firm during use, difficult drop-off, pin be easy-rupturing not also.
2. the utility model adopts and to establish a wedge shape through hole at the pin rod end of pin, makes simply, and only need beat that the insertion end of bayonet lock is just desirable to go out bayonet lock, convenient disassembly during dismounting.
Description of drawings
Fig. 1 is the plan view of the utility model pin.
Fig. 2 is that the B-B of Fig. 1 is to sectional view.
Fig. 3 is that the A-A of Fig. 1 is to sectional view.
Each digital implication is among the figure: 1, pin cap, 2, pin rod, 3, the wedge shape through hole.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, pin of the present utility model comprises pin cap 1, pin rod 2, and described pin rod 2 ends are provided with a wedge shape through hole 3 (as shown in Figure 2),
In order to adapt to different Environmental Conditions, the pin rod 2 of above-mentioned pin can be for cylindrical or square.
For safety is firm more, above-mentioned wedge shape through hole 3 crosses the axis (as shown in Figure 3) of pin rod 2.
During use the wedge shape bayonet lock is inserted from wedge shape through hole 3 wide-aperture ends, the structural member that connects is stuck between bayonet lock and the pin cap 1.The wedge shape bayonet lock that matches when shape and wedge shape through hole from the large aperture end of wedge shape through hole 3 insert the back and wedge shape through hole 3 inwall surface of contact big, more firm during use, difficult drop-off, pin be easy-rupturing not also.Because the big end of aperture one end of wedge shape through hole 3 is little, when impacting the bayonet lock insertion end, be easy to make bayonet lock from the wedge shape through hole, to break away from taking-up, convenient disassembly again.
Claims (4)
1. a pin comprises pin cap (1) and pin rod (2), it is characterized in that: the end of described pin rod (2) is provided with a wedge shape through hole (3).
2. a kind of pin according to claim 1 is characterized in that: described wedge shape through hole (3) crosses the axis of pin rod (2).
