Description
Technical field
The utility model is related to hardware field of components, and in particular to a kind of spring split pin.
Background technology
Existing spring cotter pin configuration is various, and nnti-off mode includes that flexible deformation is locking or by turning over after the completion of fixing
It rolls over shank and realizes that positioning and locking, fold shank realize that its shank of positioning and locking can not often carry out being dismounted for multiple times recycling, and
Flexible deformation is locking often to realize that anticreep, anticreep performance do not turn down shank and realize positioning and locking using shank own resilient
That comes is reliable, is easy to be detached under the action of encountering external force.
Utility model content
Based on the above issues, the utility model aim is to provide a kind of simple in structure, fixation, bullet convenient for production
Spring split pin.
In view of the above problems, providing following technical solution：A kind of spring split pin, including constriction, the constriction
In a ring by wire bending, the inflection of wire both ends extends parallel to each other to form positioning region towards the annular center of circle direction, institute
Positioning region development length is stated more than constriction annular diameter and is close to one side outer wall and extends on the outside of constriction.
In above structure, in the end of axis or bar, radially direction opens up a pin hole, when mounted first inserts positioning region
After entering pin hole, constriction is dug upwards, so that constriction is raised and is further inserted into pin hole for positioning region and space is provided, work as positioning region
Constriction is unclamped after being fully inserted into pin hole, constriction is sprung back and is placed on immediately in the outer cylindrical wall of axis or bar, to realize anticreep.
The utility model is further arranged to, and the positioning region development length is more than constriction annular diameter 3mm to 10mm.
In above structure, according to the axis or bar of different-diameter, the constriction of design its annular radius also each not phase can be caused
Together, therefore, in order to ensure that constriction positioning region when buckling into can effectively be supported, therefore its optimal design length is greater than about
Beam portion annular diameter 3mm to 10mm.
The utility model is further arranged to, and the constriction and positioning region are spring steel material.
In above structure, have the advantages that elasticity is good.
The utility model is further arranged to, and the constriction and positioning region surface are equipped with nigrescence layer.
The utility model is further arranged to, and the constriction and positioning region surface are equipped with chrome layer.
The utility model is further arranged to, and the constriction and positioning region surface are equipped with Teflon corrosion-inhibiting coating.
In above structure, nigrescence layer, chrome layer, Teflon corrosion-inhibiting coating can effectively prevent constriction and positioning region to corrode
It gets rusty.
The beneficial effects of the utility model：In the end of axis or bar, radially direction opens up a pin hole, first when mounted
After pin hole is inserted into positioning region, constriction is dug upwards, so that constriction is raised and is further inserted into pin hole for positioning region and sky is provided
Between, constriction is unclamped after positioning region is fully inserted into pin hole, constriction is sprung back and is placed on immediately in the outer cylindrical wall of axis or bar, from
And realize anticreep, have the advantages that simple in structure, fixation, convenient for production.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the structural schematic diagram after the utility model installation.
Figure label meaning：10- constrictions；The positioning regions 11-；A- pin holes.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
With reference to figure 1 and Fig. 2, a kind of spring split pin as shown in Figures 1 and 2, including constriction 10, the constriction 10
In a ring by wire bending, the inflection of wire both ends extends parallel to each other to form positioning region 11 towards the annular center of circle direction,
11 development length of the positioning region, which is more than 10 annular diameter of constriction and is close to one side outer wall, extends to 10 outside of constriction.
In above structure, in the end of axis or bar, radially direction opens up a pin hole a, when mounted first by positioning region 11
After being inserted into pin hole a, constriction 10 is dug upwards, so that constriction 10 is raised and is further inserted into pin hole a for positioning region 11 and sky is provided
Between, constriction 10 is unclamped after positioning region 11 is fully inserted into pin hole a, constriction 10 springs back and be placed on the outside cylinder of axis or bar immediately
On wall, to realize anticreep.
In the present embodiment, 11 development length of the positioning region is more than 10 annular diameter 3mm to 10mm of constriction.
In above structure, according to the axis or bar of different-diameter, can cause the constriction 10 of design its annular radius also it is each not
It is identical, therefore, in order to ensure that the positioning region 11 when buckling into of constriction 10 can effectively be supported, therefore positioning region 11 its most preferably set
It is more than 10 annular diameter 3mm to 10mm of constriction to count length.
In the present embodiment, the constriction 10 and positioning region 11 are spring steel material.
In above structure, have the advantages that elasticity is good.
In the present embodiment, the constriction 10 and 11 surface of positioning region are equipped with nigrescence layer（It is not shown in figure）.
In the present embodiment, the constriction 10 and 11 surface of positioning region are equipped with chrome layer（It is not shown in figure）.
In the present embodiment, the constriction 10 and 11 surface of positioning region are equipped with Teflon corrosion-inhibiting coating（It is not shown in figure）.
In above structure, nigrescence layer, chrome layer, Teflon corrosion-inhibiting coating can effectively prevent constriction 10 and positioning region 11
Rust corrosion.
The beneficial effects of the utility model：In the end of axis or bar, radially direction opens up a pin hole a, first when mounted
After pin hole a is inserted into positioning region 11, constriction 10 is dug upwards, so that constriction 10 is raised and is further inserted into pin for positioning region 11
Hole a provide space, after positioning region 11 is fully inserted into pin hole a unclamp constriction 10, constriction 10 spring back and be placed on immediately axis or
In the outer cylindrical wall of bar, to realize anticreep, has the advantages that simple in structure, fixation, convenient for production.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications, above-mentioned vacation can also be made
If these improvements and modifications also should be regarded as the scope of protection of the utility model.
