Abstract
The utility model provides a coupler pin bolt, including the pin body, pin body one end is provided with the screw rod, and the other end of pin body is provided with the handle post, and handle post surface is provided with the handle hole, and the handle hole the central axis is not parallel to each other with pin body length direction. Adopt the technical scheme of the utility model, when dismouting pintle bolt, operating tool or operator's hand can be applyed the operating force within the operation hole, carry out the dismouting to it within the operation hole of partly stretching into the pintle bolt through with operating tool or operator promptly, operating tool can select screwdriver or crowbar etc., accomplish and make the pintle bolt tighten, back out, insert or extract operation such as, because pintle bolt impetus is within the operation hole, no longer be the friction connection relation between operating force and the pintle bolt, can effectively prevent to skid, make pintle bolt easy dismounting, time saving and labor saving, improve dismouting efficiency.
Description
Technical Field
The utility model relates to a machine parts technical field especially indicates a coupler pin bolt.
Background
The shaft coupling is a common mechanical part, is used for connecting between two axis of rotation, is used for transmitting power, the kind of shaft coupling is many, mainly divide into rigid coupling and flexible coupling two major categories, wherein rigid coupling divide into membrane type shaft coupling again, ring flange shaft coupling etc. flexible coupling divide into plum blossom formula shaft coupling again, elasticity pin coupling, spring shaft coupling, universal joint shaft coupling etc. wherein, the pin bolt is the traditional chinese medicine spare part in the elasticity pin shaft coupling, when making the shaft coupling connect two transmission shafts, need carry out frequent dismouting to the pin bolt, current pin bolt generally is solid structure, when dismouting, operating tool or operator's hand can only apply the effort on the surface of pin bolt, the condition of skidding appears easily, it is inconvenient to use, waste time and energy.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a coupler pin bolt.
The utility model discloses a following technical scheme can realize.
The utility model provides a coupler pin bolt, including the pin body, pin body one end is provided with the screw rod, the other end of pin body is provided with the handle post, handle post surface is provided with the handle hole, handle hole the central axis with pin body length direction is not parallel to each other.
The central axis of the operation hole is perpendicular to the length direction of the pin body.
The cross section of the handle column is rectangular.
The operation hole is a through hole with a circular cross section.
The cross section of the handle column is rectangular, the operating hole is a through hole with a circular cross section, and the aperture of the operating hole is one third to one half of the width of the handle column.
The pin body is in a stepped shaft shape, and the central axis of the handle column and the central axis of the pin body are overlapped.
The pin body is in a stepped shaft shape, and the central axis of the screw rod is overlapped with the central axis of the pin body.
The pin body, the screw rod and the handle column are manufactured and formed integrally.
The beneficial effects of the utility model reside in that: adopt the technical scheme of the utility model, through set up the handle post on the pin body, set up the handle hole on the handle post simultaneously, when dismouting pin bolt, operating tool or operator's hand can be applyed the operating force within the operating hole, carry out the dismouting to operating tool or operator's hand within stretching into the operating hole of pin bolt promptly, operating tool can select screwdriver or crowbar etc. accomplish to make the pin bolt tighten, screw out, insert or extract operation such as, because the pin bolt impetus is within the operating hole, no longer be the frictional connection relation between operating force and the pin bolt, can effectively prevent to appear skidding, make pin bolt easy dismounting, time saving and labor saving, improve dismouting efficiency.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1-pin body, 2-screw, 3-handle column, 31-operation hole.
Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1, the utility model provides a coupler pin bolt, including pin body 1, 1 one end of pin body is provided with screw rod 2, and the other end of pin body 1 is provided with handle post 3, and 3 surfaces on the handle post are provided with operation hole 31, and operation hole 31 the central axis is not parallel to each other with 1 length direction of pin body.
Adopt the technical scheme of the utility model, through set up handle post 3 on pin body 1, set up operation hole 31 on handle post 3 simultaneously, when dismouting pin bolt, operating tool or operator's hand can be applyed the operating force within operation hole 31, carry out the dismouting to operating tool or operator's hand within 31 through stretching into pin bolt promptly, operating tool can select screwdriver or crow bar etc. accomplish to make pin bolt tighten, screw out, insert or extract operation such as, because pin bolt impetus is within operation hole 31, no longer be the friction joint relation between operating force and the pin bolt, can effectively prevent to appear skidding, make pin bolt easy dismounting, time saving and labor saving, improve dismouting efficiency.
Further, the central axis of the operation hole 31 is perpendicular to the longitudinal direction of the pin body 1. The stem 3 is preferably rectangular in cross-section. The operation hole 31 is a through hole having a circular cross section. The diameter of the operation hole 31 is one third to one half of the width of the stem 3.
The pin body 1 is stepped shaft-shaped, and the central axis of the shank 3 and the central axis of the pin body 1 overlap each other. The pin body 1 is in a stepped shaft shape, and the central axis of the screw rod 2 is superposed with the central axis of the pin body 1. The pin body 1, the screw 2 and the handle column 3 are integrally manufactured. Adopt the technical scheme of the utility model, shaft coupling pin bolt simple structure, low in manufacturing cost is honest and clean, easy dismounting can extensively popularize and apply in the machine parts field.
