Second main body of hollow notch opposite side, the first main body are equipped with through hole, fastener hole include the through hole being placed in the first main body and
The threaded hole being placed in the second main body, the aperture of threaded hole are gradually increased by one end to one end away from through hole of close through hole,
The cone angle of threaded hole is 1-3 degree, and the side wall that the second main body is placed in hollow notch is in evagination arcuate structure, the outside of the second main body
Wall is in concave arc structure.
By using above-mentioned technical proposal, when bolt is when screwing, the second main body can produce shape to the side of the first main body
Become, increase the conflict power of connecting hole and track pin, since the side wall that the second main body is placed in hollow notch is in evagination arcuate structure,
The lateral wall of second main body is in concave arc structure, can increase the elasticity of the second main body, improves the frictional force after connection, due to
Threaded hole has certain taper, easy to the connection with screw rod.
The utility model is further arranged to：The connector body further includes the arc of the first main body of connection and the second main body
Shape portion, the wall thickness of curved portion close to one end of the first main body to one end close to the second main body by being gradually reduced.
By using above-mentioned technical proposal, connector body connects structure by the first main body, two curved portions with the second main body
Into, since the wall thickness of curved portion close to one end of the first main body to close to one end of the second main body by being gradually reduced, then curved portion
Thicker with the wall thickness of the second main body connecting pin, structural strength is preferable, and curved portion and the wall thickness of the second main body connecting pin are relatively thin, elasticity
Preferably, it is easy to produce elastic deformation, increases the conflict power of connecting hole and track pin.
The utility model is further arranged to：The locking hole connected with connecting hole is additionally provided with the connector body.
By using above-mentioned technical proposal, locking hole is placed on the connecting pin of the first main body and curved portion, and locking hole is equipped with
Screw, when connecting hole and crawler belt pin connection, being screwed by screw makes screw be contradicted with track pin, increases connecting hole and track pin
Between bonding strength.
The utility model is further arranged to：The step connected with through hole is additionally provided with the lateral wall of first main body
Hole.
By using above-mentioned technical proposal, stepped hole is adapted to the head of bolt, is reduced bolt head and is excessively protruded first
The lateral wall of main body.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of connector embodiment of the utility model.
Fig. 2 is a kind of A-A of connector embodiment Fig. 1 of the utility model to structure diagram.
Fig. 3 is a kind of overlooking the structure diagram of connector embodiment Fig. 1 of the utility model.
Embodiment
It is described further referring to figs. 1 to a kind of connector embodiment of 3 pairs of the utility model.
A kind of connector, including connector body, the connector body are equipped with fastener hole 1 and for connecting two shoes
Connecting hole 2 with pin, is equipped with perforative hollow notch 3 between two connecting holes 2, it is characterised in that：The connector body also wraps
The first main body 4 for being placed in hollow 3 side of notch and the second main body 5 for being placed in hollow 3 opposite side of notch are included, fastener hole 1 includes putting
In the through hole 6 in the first main body 4 and the threaded hole 7 being placed in the second main body 5, the aperture of threaded hole 7 is by close to one end of through hole 6
