Abstract
The utility model provides a mounting structure for a damping pin, which reduces the abrasion of the excircle surface of the damping pin, prolongs the life of the damping pin, and ensures the normal production. The mounting structure comprises two connecting pieces, wherein mounting holes are arranged at the corresponding positions on the mutual touch surfaces of the connecting pieces; one end of the damping pin is connected with one connecting piece in a fastening way; the out-of-band circular end of the damping pin is sleeved in the mounting hole of the other connecting piece; the excircle surfaces of the damping pin is clung to the inner circle surfaces of the corresponding mounting holes; and the mounting structure is characterized in that a vent hole at the lower part of the mounting hole of the other connecting piece is a blind hole.
Description
Technical field
The utility model relates to the technical field of mechanical connecting structure, is specially a kind of mounting structure of damping pin.
Background technique
The mounting structure of existing damping pin is in the corresponding position of contact jaw face of two connected elements and has mounting hole, and the mounting hole of a side has the exhaust port that runs through therein then; Connect two connected elements through the damping pin again, during connection, an end of damping pin is fastenedly connected the connected element that does not have exhaust port; The other end of damping pin is set in the connected element that has exhaust port, and the damping pin is done the time spent, relies on damping pin periphery and the frictional force between the corresponding exhaust port to control the coupled condition of two connected elements; Under this structure; The wearing and tearing of damping pin periphery are very fast, cause the life-span of damping pin short, and influence is produced normally.
Summary of the invention
The utility model provides a kind of mounting structure of damping pin, and it makes that wearing and tearing life-span slow, the damping pin of periphery of damping pin is long, guarantees ordinary production.
A kind of mounting structure of damping pin; It comprises two links; The corresponding position of the face that is in contact with one another of said link has mounting hole, and damping pin embedding one end is fastenedly connected one of them link, and the outer nose circle of the band of damping pin is set in the mounting hole of said another link; The periphery of said damping pin is close to the inner headed face of corresponding mounting hole, it is characterized in that: the exhaust port of the mounting hole bottom of said another link is a blind hole.
It is further characterized in that: the bottom of the mounting hole of said another link has the exhaust port that runs through, and the bottom plug of said exhaust port is equipped with plug.
After adopting the structure of the utility model; Because the lower discharge hole of the link of suit damping pin periphery is a blind hole; So the periphery of damping pin cooperates the vacuum negative pressure that forms to replace frictional force before to control the coupled condition of two links with mounting hole; The suffered friction of the periphery of damping pin reduces greatly, makes that wearing and tearing life-span slow, the damping pin of periphery of damping pin is long, guarantees ordinary production.

Fig. 1 is the plan view structural representation of the specific embodiment one of the utility model;
Fig. 2 is the plan view structural representation of the specific embodiment two of the utility model.
Embodiment
See Fig. 1, Fig. 2; It comprises two links 1,2; The corresponding position of the face that is in contact with one another of link 1,2 has mounting hole 3,4; Damping pin 5 one ends are fastenedly connected link 1, and the outer nose circle of the band of damping pin 5 is nested to be loaded in the mounting hole 4 of link 2, and the periphery 6 of damping pin 5 is close to the inner headed face of the mounting hole 4 of link 2.
Specific embodiment one, see Fig. 1: the exhaust port 7 of mounting hole 4 bottoms of link 2 is blind hole.
Specific embodiment two, see Fig. 2: the bottom of the mounting hole 4 of link 2 have the exhaust port 7 that runs through ', exhaust port 7 ' the bottom plug plug 8 is housed.
Claims (2)
