Abstract
The utility model relates to a shaft pin comprising a shaft head, a shaft body and a baffle plate. The shaft head and the baffle plate are respectively arranged on two sides of the shaft body; one side of the shaft body close to the shaft head is provided with a groove; the shaft head is provided with an oil inlet hole; the shaft body is provided with an oil outlet hole; the oil inlet hole is communicated with and perpendicular to the oil outlet hole; and a diameter of the oil outlet hole is smaller than a diameter of the oil inlet hole. During the use of the shaft pin, lubricating oil is poured into the oil inlet hole and lubrication degree of a contact part between the shaft pin and anobject fixed by the shaft pin is increased, so that the shaft pin can be easily detached from the object fixed by the shaft pin; and the diameter of the oil outlet hole is smaller than the diameter of the oil inlet hole, so that the lubricating oil poured into the oil inlet hole flows slowly out of the oil outlet hole, thereby improving utilization rate of the lubrication oil.
Description
Technical field
The utility model relates to a kind of connected element, is specifically related to a kind of easily detachable pivot pin.
Background technique
Pivot pin is a kind of for being connected and fixed two connected elements that have the object of through hole, and pivot pin is after long-time the use, and it is easy stuck because getting rusty, not quick detachable with the contacting part between the object be connected and fixed.
The model utility content
The utility model purpose is that a kind of easily detachable pivot pin is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pivot pin, comprise spindle nose, and axle body and baffle plate, described spindle nose and baffle plate separation are in the both sides of axle body; Described axle body is provided with groove in the side near spindle nose; Be respectively equipped with the oil inlet hole and the oil outlet that are interconnected on described spindle nose and axle body, and described oil inlet hole is vertical with oil outlet arranges.
Preferably, the diameter of described oil outlet is less than the diameter of oil inlet hole.
Preferably, the edge of described spindle nose is provided with chamfering.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Pivot pin described in the utility model, be respectively arranged with the oil inlet hole and the oil outlet that are interconnected on its spindle nose and axle body, this makes pivot pin in the process of using, can from oil inlet hole, inject lubricant oil, increase the lubricity of contacting part between itself and institute's fixed object, and then just can easily disassemble pivot pin from fixing object; The diameter of its oil outlet is less than the diameter of oil inlet hole simultaneously, and the lubricant oil injected from oil inlet hole can must be flowed out from oil outlet is slow, has improved the utilization rate to lubricant oil.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The stereogram that accompanying drawing 1 is pivot pin described in the utility model;
The sectional view that accompanying drawing 2 is pivot pin described in the utility model;
Wherein: 1, spindle nose; 2, axle body; 3, baffle plate; 4, groove; 5, oil inlet hole; 6, oil outlet; 7, chamfering.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1,2 is a kind of pivot pin described in the utility model, comprises spindle nose 1, axle body 2 and baffle plate 3, described spindle nose 1 and the both sides of baffle plate 3 separations at axle body 2; Described axle body 2 is provided with groove 4 in the side near spindle nose 1; Be respectively equipped with the oil inlet hole 5 and the oil outlet 6 that are interconnected on described spindle nose 1 and axle body 2, and described oil inlet hole 5 setting vertical with oil outlet 6.
The diameter of wherein said oil outlet 6 is less than the diameter of oil inlet hole 5; The edge of described spindle nose 1 is provided with chamfering 7.
Pivot pin described in the utility model, be respectively arranged with oil inlet hole 5 and the oil outlet 6 be interconnected on its spindle nose 1 and axle body 2, this makes pivot pin in the process of using, can from oil inlet hole 5, inject lubricant oil, the lubricant oil injected will flow out from oil outlet 6 along hole, take the contacting part of itself and institute's fixed object to, increase the lubricity between them, and then just can easily disassemble pivot pin from fixing object; The diameter of its oil outlet 6 is less than the diameter of oil inlet hole 5 simultaneously, and the lubricant oil injected from oil inlet hole 5 can must be flowed out from oil outlet 6 is slow, has improved the utilization rate to lubricant oil.
Be only below concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
