Abstract
The utility model relates to a kind of anticreep articulating pin, shank two sides are in gradually smaller taper, and tapered jacket inside of the two sides for fastening is in the shape changed from small to big, and tapered jacket is combined closely with shank when being fixed together with shank, realizes the purpose of fixed shank.The utility model mainly includes tapered jacket, tapering articular pin, firm screw, it is characterised in that is cylinder among tapering articular pin, diametrically gradually smaller cone cell, tapering articular pin both ends are equipped with screw hole at A from B for two sides；Tapered jacket is cylindricality cap-like structure, and the diameter from C to D becomes larger；Housing screw hole is arranged in tapered jacket center location；Fastening screw and the screw hole at tapering articular pin both ends match, and fastening screw passes through the housing screw hole among tapered jacket, connect with screw hole, tapered jacket is fastened on tapering articular pin；Tapering articular pin both ends are in symmetrical structure.
Description
Technical field
The utility model relates to fastening means technical field more particularly to a kind of anticreep articulating pins.
Background technique
It in installing engineering, is mostly connected using pin shaft between rod piece, there is easy peace to tear open and be hardly damaged for pin shaft connection
The advantages of connector, what the anticreep measure of pin shaft was generally taken is the insertion opening pin after the drilling of its tail end, or by pin shaft tail portion
Fastening nut etc. is equipped with after being processed into silk mouth.But such conventional pin axis connection for excavator machinery wall connect with oil cylinder when,
It is easy loosening, insecure, the easy influence equipment operation precision of loosening, brings technical problem to the accurate excavator that operates.
Summary of the invention
Utility model aims to solve above-mentioned the shortcomings of the prior art, provide a kind of anticreep articulating pin, pin
Body two sides are in gradually smaller taper, and two sides are for being in the shape changed from small to big inside the tapered jacket of fastening, solid with shank
Tapered jacket is combined closely with shank when being scheduled on together, realizes the purpose of fixed shank.
The utility model mainly includes tapered jacket, tapering articular pin, firm screw, it is characterised in that in tapering articular pin
Between be it is cylindrical, two sides diametrically gradually smaller cone cell to A at from B, tapering articular pin both ends are equipped with screw hole；Tapered jacket
For cylindricality cap-like structure, the diameter from C to D is become larger；Housing screw hole is arranged in tapered jacket center location；Fastening screw and cone
The screw hole at shape articulating pin both ends matches, and fastening screw passes through the housing screw hole among tapered jacket, connect with screw hole, by taper
Housing is fastened on tapering articular pin；Tapering articular pin both ends are in symmetrical structure.
Further, tapered jacket is equipped with gap, and fastening screw enters that screw hole length is longer, and the position D of tapered jacket more connects
The B location of nearly tapering articular pin supports in the gap of tapered jacket greatly in the pressure of the big generation of B location diameter, and gap, which becomes larger, to be made
Tapered jacket fixed force is obtained to become larger.

Specific embodiment
The utility model specific implementation is provided with reference to the accompanying drawing:
As shown, the utility model includes tapered jacket 1, tapering articular pin 2, firm screw 3, it is characterised in that taper
It is cylinder among articulating pin 2, diametrically gradually smaller cone cell, 2 both ends of tapering articular pin are equipped with spiral shell at A from B for two sides
Hole 4；Tapered jacket 1 is cylindricality cap-like structure, and the diameter from C to D becomes larger；Housing spiral shell is arranged in 1 center location of tapered jacket
Hole 6；Fastening screw 3 and the screw hole 4 at 2 both ends of tapering articular pin match, and fastening screw 3 passes through the housing among tapered jacket 1
Screw hole 6 is connect with screw hole 4, and tapered jacket 1 is fastened on tapering articular pin 2；2 both ends of tapering articular pin are in symmetrical structure.
Tapered jacket 1 is equipped with gap 5, and fastening screw 3 is longer into screw hole length, and the position D of tapered jacket 1 is closer to cone
The B location of shape articulating pin 2, so what tapered jacket receiving was gradually increased from the pressure that tapering articular pin supports outward, in B location
Diameter maximum is that the gap 5 of tapered jacket 1 is supported to maximum by the pressure generated, and gap 5 becomes larger so that tapered jacket 1 is to interior
The fixed force of fastening becomes larger, so that entire anticreep articulating pin be made to become securely to be not easy to loosen, keeps oil cylinder and excavating machinery wall tight
Solid phase connects, and improves the integrated operation precision of excavator.
