3 extract connecting seat 22, dismantle, is easy to assembly.
Further, referring to Fig. 4, a kind of embodiment as haulage gear provided by the utility model, limit
Position groove 223 includes first point of groove 2231 and second point of groove 2232, second point of groove 2232 compared with first point of groove 2231 close to connecting seat 22,
The sidepiece of first point of groove 2231 is turned on the sidepiece of second point of groove 2232.The roof 22322 of second point of groove 2232 plays backstop limit
Position column 31 departs from the effect of the stopper section of limiting slot 223, with pressed by external force towing pin 3, makes trussed shore from first point of groove of conducting
It is caught at the notch 2233 of the sidepiece of 2231 sidepiece and second point of groove 2232 in second point of groove 2232, passes through second point of groove 2232
Two side realize the circumferentially positioned of towing pin 3, pass through bottom wall 22323 and roof 22322 (second point of groove of second point of groove 2232
2232 bottom wall 22323 and roof 22322 for the side wall of limiting slot 223 a part) realize the axially position of towing pin 3, no
It is only simple in structure, it is easily assembled, dismantles, while is also beneficial to the structural stability of increase haulage gear.
Further, also referring to Fig. 1 and Fig. 4, as a kind of specific real of haulage gear provided by the utility model
Apply mode, the size for turning on the notch 2233 of the sidepiece of first point of groove 2231 and the sidepiece of second point of groove 2232 is less than limited post 31
Size and can be by foreign compulsion limited post 31 by notch 2233, the size of second point of groove 2232 is more than limited post 31
Size.The size of notch 2233 is small compared with limited post 31, applies lower pressure during assembling to spacer pin, can force limited post 31 from the
One point of groove 2231 slips into second point of groove 2232 through notch 2233, and when dismounting applies pull out force to towing pin 3, can force limited post 31
First point of groove 2231 is slipped into through notch 2233 from second point of groove 2232, so as to fulfill installation of the towing pin 3 on connecting seat 22, is torn open
Unload, it is easy to use, additionally it is possible to which that when avoiding the haulage gear from working, towing pin 3 skids off and out of stock from notch 2233；Second point of groove 2232
Size it is larger, provide certain activity space for limited post 31, it is allowed to which towing pin 3 is beated, and avoids stress concentration, increases structure
Stability.
Further, also referring to Fig. 1 and Fig. 4, as a kind of specific real of haulage gear provided by the utility model
Mode is applied, the bottom wall 22312 of first point of groove 2231 is tilted towards second point of groove 2232.The bottom wall 22312 of first point of groove 2231 is made
For a part for the side wall of limiting slot 223, on the one hand it, which is obliquely installed, plays the work that limited post 31 is imported to second point of groove 2232
With on the other hand can applying a direction second to the limited post 31 of bounce and divide the component of groove 2232, avoid towing pin 3 from jumping out
Connecting seat 22 and cause it is out of stock, securely and reliably.
Further, also referring to Fig. 1 and Fig. 4, as a kind of specific real of haulage gear provided by the utility model
Apply mode, the two side of the two side 22311 of first point of groove 2231 and second point of groove 2232 is set along the axial direction of limited post 31, the
Side wall 22321 of the bottom wall 22323 of the roof 22322 of two points of grooves 2232 and second point of groove 2232 perpendicular to second point of groove 2232.
During such 3 stress of towing pin, due to the limitation of the side wall of first through hole 221 on connecting seat 22, the radially movable space of towing pin 3
It is small, and when towing pin 3 rotates, second point of 2232 side wall of groove promotes limited post 31 reversely to turn the reaction force of limited post 31
It is dynamic, the direction without limited post 31 to be oriented to first point of groove 2231, and when axial activity occurs for towing pin 3, second point of groove
2232 bottom wall 22323 promotes the reaction force of limited post 31 roof 22322 of limited post 31 towards second point of groove 2232 to live
Dynamic, without being formed towards the component for deviating from second point of groove 2232 from notch 2233, the roof 22322 of second point of groove 2232 is to spacing
The anti-work of column 31, which is made every effort to promote, makes bottom wall 22323 activity of the limited post 31 towards second point of groove 2232, without forming direction from notch
The component of 2233 second point of groove 2232 of abjection, avoid towing pin 3 from jumping out connecting seat 22 and cause it is out of stock, it is safer reliable.
Also referring to Fig. 1 and Fig. 2, now haulage gear provided by the utility model is illustrated.Tractor, including car
Body 1, vehicle body 1 are equipped with the haulage gear that foregoing any embodiment is addressed.
Preferably, mounting hole 11 is equipped with also referring to Fig. 1 and Fig. 2, vehicle body 1, pressure sensor 4 and base 21 are arranged on
The same side of vehicle body 1, and pressure sensor 4 is used for fixed traction pin 3 between base 21 and vehicle body 1 on connecting seat 22
One end extends the opposite side of vehicle body 1 through mounting hole 11.It is simple in structure, it is easily assembled, pressure sensor is installed on vehicle body 1
4, the 22 self installation hole 11 of connecting seat of traction seat 2 is worn to the opposite side of vehicle body 1, then base 21 is fixed on vehicle body 1, you can
Realize the assembling of traction seat 2 and relevant portion on tractor, and can be caught in or extract as needed towing pin 3, towing pin 3 with
When hook coordinates breakdown trailer, hook reverse drawing towing pin 3, towing pin 3 drives the gear of base 21 to lean against vehicle body 1 by connecting seat 22
On, not only ensured the connection reliability of haulage gear and vehicle body 1, but also can accurate Measuring hook tractive force, improve security.
Further, also referring to Fig. 1 and Fig. 2, one kind specific implementation as tractor provided by the utility model
