Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of pin shaft connection structure, cotter pin effectively can be avoided to wear and tear or cut off, improve pinned connection installation efficiency, and can effectively play pin shaft end fixation.
To achieve these goals, a kind of pin shaft connection structure that the utility model adopts, comprise the bearing pin without a head that can be arranged in link, bearing pin two ends without a head all have pin shaft hole, also comprise the interstage sleeve that can be sleeved on for bearing pin axial limiting on bearing pin without a head, interstage sleeve is by vertical pin and pinned connection without a head, and one end of vertical pin has pin shaft hole, and the perforate end of vertical pin is equipped with fixedly uses locking mechanism.
Further, interstage sleeve is sleeved on the axle head of bearing pin without a head, interstage sleeve has the mounting hole installing vertical pin, and interstage sleeve is fixed on bearing pin without a head after passing the mounting hole on interstage sleeve, the pin shaft hole on bearing pin without a head by vertical pin.
Further, locking mechanism comprise for vertical pin axial limiting cotter pin, for limiting cotter pin wearing and tearing or the block cut off, described cotter pin is arranged in the pin shaft hole of vertical pin, and described block is arranged on vertical pin.
Further, block is arranged between cotter pin and interstage sleeve.
Further, the aperture of interstage sleeve and the axle head diameter of bearing pin without a head coincide.
Further, between interstage sleeve and link, backing plate is installed.
Compared with existing pinned connection mode, pin shaft connection structure of the present utility model has the following advantages:
(1) install interstage sleeve at the axle head of bearing pin without a head, by interstage sleeve rotation process, vertical pin can be made interstage sleeve and bearing pin without a head to be cascaded easily, and installation efficiency is high.
(2) pinning structure by installing at the perforate end of vertical pin, effectively vertical pin being fixed, avoiding the position of vertical pin moving influence bearing pin without a head, effectively can limit cotter pin wearing and tearing simultaneously or cut off, making connection safety and reliability.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 4 and Figure 5, a kind of pin shaft connection structure, comprise the bearing pin without a head 1 that can be arranged in link, bearing pin 1 two ends without a head all have pin shaft hole, also comprise the interstage sleeve 8 that can be sleeved on for bearing pin axial limiting on bearing pin 1 without a head, interstage sleeve 8 is connected with bearing pin 1 without a head by vertical pin 12, and one end of vertical pin 12 has pin shaft hole, and the perforate end of vertical pin 12 is equipped with fixedly uses locking mechanism.
Interstage sleeve 8 is sleeved on the axle head of bearing pin 1 without a head, interstage sleeve 8 has the mounting hole installing vertical pin 12, interstage sleeve 8 is fixed on bearing pin 1 without a head after passing the mounting hole on interstage sleeve 8, the pin shaft hole on bearing pin without a head 1 by vertical pin 12, by vertical pin 12, fixing interstage sleeve 8 and bearing pin without a head 1 are installed, install simple and convenient, rapid operation, and interstage sleeve 8 rotates conveniently, is easy to vertical pin 12 and finds connection hole accurately.
As further improvement of the utility model, locking mechanism comprises the cotter pin 10 for vertical pin 12 axial limiting, for limiting the block 11 that cotter pin 10 is worn and torn or cut off, described cotter pin 10 is arranged in the pin shaft hole of vertical pin 12, described block 11 is arranged on vertical pin 12, vertical pin 12 is fixed by cotter pin 10, pin shaft end fixation can be played, can ensure that again vertical pin 12 can not come off, the installation of cotter pin 10, simple and easy to use, the block 11 installed on vertical pin 12 in addition, can avoid using vertical pin 12 that wearing and tearing occur for a long time cut off or come off, block 11 can effectively play a protective role to vertical pin 12.
Block 11 is arranged between cotter pin 10 and interstage sleeve 8, effectively avoids cotter pin 10 to contact with interstage sleeve 8, prevents cotter pin 10 from wearing and tearing and cuts short or come off.
The aperture of interstage sleeve 8 and the axle head diameter of bearing pin without a head 1 coincide, and ensure that interstage sleeve 8 can just by fixing for pin shaft end suit, avoid both excesssive gaps, bearing pin 1 without a head installs shakiness in interstage sleeve 8, affects bearing pin and normally uses.
