With pipe point, to facilitate during walking in tow, significantly reduce the heavy burdens.
For example, Chinese patent literature disclose a kind of be provided with improve pull bar draw-bar box [application number:
Cn201220039908.x]: include draw-bar box body and pull bar, described draw-bar box body is provided with pull bar bracing frame, described pull bar
Bracing frame is provided with pull bar storage tank, described pull bar in described pull bar storage tank, described pull bar and pull bar storage tank and institute
State pull bar bracing frame outward flange to arrange at an angle；Described pull bar is the irregular pull bar of shape of cross section.The program can reach
To making pull bar fixedly secure, reduce the purpose that pull bar rocks and damages.
Although above-mentioned scheme have many advantages, such as above, also at least there is following technical problem in the program: draw
The structure design of bar is unreasonable, particularly the junction structure of pull bar and handle, and it leads to easily rotate and come off due to using,
Service life is shorter.
Utility model content
The purpose of this utility model is for the problems referred to above, provides a kind of design more reasonable, it can be avoided that circumferentially rotate and
The pull bar of the draw-bar box that can increase the service life.
For reaching above-mentioned purpose, the utility model employs following technical proposal: the pull bar of this draw-bar box includes expansion link
With the handle being connected to flexible rod rear end, it is connected with the axle sleeve with the circumferentially fixed connection of expansion link in flexible rod rear end, in handle
Front end be connected with cooperation pin with the circumferentially fixed connection of handle, be provided with internal spline in the inwall of axle sleeve, in cooperation pin
Outer wall is provided with the external splines being meshed with described internal spline, described axle sleeve is arranged with and is prevented from described handle relatively
The clip of expansion link axial movement.
In this application, the structure of cooperation pin is combined due to being provided with axle sleeve, and the structure of external splines and internal spline,
It is capable of circumferentially fixed, simultaneously in conjunction with the structure of clip, be capable of axial fixation, design is more reasonable and assembles more
Plus simple, virtually extend service life.
In the pull bar of above-mentioned draw-bar box, described cooperation pin is intercepted by tubing to be made.
In the pull bar of above-mentioned draw-bar box, described axle sleeve is made of plastics, the middle part of axle sleeve be provided with some along
Form connecting portion, described hoop sleeve is in the connection of axle sleeve between the axially arranged bar hole of axle sleeve and adjacent two bar holes
In portion.
In the pull bar of above-mentioned draw-bar box, described connecting portion outer wall is provided with groove and the connection of described groove forms ring
Shape groove, described hoop sleeve is on cannelure.
In the pull bar of above-mentioned draw-bar box, described handle is t-shaped.
In the pull bar of above-mentioned draw-bar box, the transverse bar of described handle is respectively arranged at two ends with rubber stopper.
Compared with prior art, the advantage of the pull bar of this draw-bar box is: 1, combines cooperation pin due to being provided with axle sleeve
The structure of son, and the structure of external splines and internal spline, are capable of circumferentially fixed, simultaneously in conjunction with the structure of clip, can
Realize the fixation of axial direction, design is more reasonable and assembles simpler, virtually extends service life.2nd, structure is simple and easy
In manufacture.
