Abstract
Tractor suspension mechanism is with round pin axle locking device includes: rotatory round pin fixing base, rotation locking round pin close piece, spring pin, packing ring, rotation locking and sell the spring, rotatory round pin fixing base rigid coupling is on tractor suspension mechanism connecting piece. Rotation locking round pin spring and two packing rings are installed on the rotation locking round pin closes the piece, and rotation locking round pin spring mounting is in the middle of two packing rings, and two spring pins are installed respectively in the A hole and B hole on the rotation locking of two packing ring outsides round pin closes the piece. Set up pinhole and elongated slot on the rotatory round pin fixing base, the pinhole should make the rotation locking round pin close can to pass through, and the elongated slot should make the spring pin pass through. The rotation locking round pin closes the piece and sells and the rotation locking handle including rotation locking, and both rigid couplings become integrative, is close to the A hole and the B hole of the setting of rotation locking handle one end on rotation locking sells, and two hole axis become 90 contained angles. The utility model discloses can effectively replace the connection and the locking of traditional tractor suspension mechanism round pin axle in general use, plain washer cooperation split pin.
Description
Technical field
The utility model belongs to tractor field, is related to a kind of tractor mounnted frame bearing pin locking device.
Background technology
The hitch of tractor is mainly made up of lower pull bar, lifting arm, gag lever post and upper connecting rod, these mechanisms generally by
The connectors such as bearing pin, lock pin, split pin are assembled, and wherein bearing pin is connected on tractor mounnted frame extensive and important
Application.Tractor mounnted frame of the prior art generally coordinates the connection and locking of split pin using bearing pin, plain washer, outward
Sight is simple and crude, and installation, dismounting need specific purpose tool, and assembly process process is poor.In utility model patent " resilient pin latch system
201520020919.7 " in, mainly it is made up of bearing pin, axle sleeve assembly and spring etc., range of application is concentrated mainly on engineering field
The locking aspect of door, window etc.；In utility model patent " a kind of latch gear 201210473108.3 ", the latch gear is utilized
Helical rotation of the handle on helicoid is converted into the linear motion of lock pin, and the rotation by handle on helicoid is made before lock pin
Enter or retreat, realize the connection between two parts and free.Do not have for tractor mounnted frame bearing pin in above-mentioned patent
And locking device makes detailed construction feature interpretation, and the emphasis protected also not in tractor mounnted frame bearing pin and locking side
Face.It is existing dilatory as tractor manufacturing enterprise and user are to the structure of tractor and the requirement more and more higher of performance
Machine hitch bearing pin connects and locking can not very well meet needs, is badly in need of being improved.
Utility model content
The purpose of this utility model is to provide a kind of compact conformation, good looking appearance, lock reliable tractor suspension machine
Structure bearing pin locking device.
The utility model is achieved through the following technical solutions above-mentioned purpose：Tractor mounnted frame bearing pin locking device,
Including：Rotating dog fixed seat, rotation lock shotpin component, resilient key, packing ring, rotation lock shotpin spring；Rotating dog fixed seat is affixed
On tractor mounnted frame connector.
Rotation lock shotpin spring and two packing rings are arranged on rotation lock shotpin component, and rotation lock shotpin spring is arranged on two
In the middle of individual packing ring, two resilient keys are separately mounted in the A holes and B holes on the rotation lock shotpin component outside two packing rings.
Pin-and-hole and elongated slot are set in rotating dog fixed seat, and pin-and-hole should enable rotation lock shotpin component pass through, and elongated slot should make
Resilient key can pass through.
Rotation lock shotpin component includes rotation lock shotpin and rotary locking handle, and both are affixed integral, and in rotation lock
Rotary locking handle one end is provided with A holes and B holes, two axially bored lines angle in 90 ° on shotpin.
The utility model is using can reach following good effect after above-mentioned technical proposal：The tractor mounnted frame bearing pin
Locking device structure is compact and cost is relatively low, easy to use and reliability, good looking appearance and without the need for specific purpose tool, and can effectively replace is passed
Bearing pin, the connection of plain washer cooperation split pin and locking that system tractor mounnted frame is generally adopted.Both bearing pin had been met convenient
Connection and lock, while and preferably improve the use reliability of tractor mounnted frame.
Description of the drawings
Fig. 1 is the structural representation of the utility model tractor mounnted frame bearing pin locking device；
Fig. 2 is the rotation lock shotpin component structural representation of the utility model tractor mounnted frame bearing pin locking device
Figure.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model will be further described.As shown in Figure 1 and 2, tractor mounnted frame pin
Shaft lock device, including：Rotating dog fixed seat 1, rotation lock shotpin component 2, split pin 3, plain washer 4, rotation lock shotpin spring
5。
Rotating dog fixed seat 1 is fixed in the end face outside of tractor mounnted frame connector 6, rotation lock shotpin spring 5
It is arranged on rotation lock shotpin component 2 with two packing rings 4, rotation lock shotpin spring 5 is arranged in the middle of two packing rings 4, two bullets
Property pin 3 be separately mounted in the A holes 2.3 and B holes 2.4 on the rotation lock shotpin component 2 of the outside of two packing rings 4.
Pin-and-hole and elongated slot are set in rotating dog fixed seat 1, and pin-and-hole should enable rotation lock shotpin component 2 pass through, and elongated slot should
Resilient key 3 is set to pass through.
Rotation lock shotpin component 2 includes rotation lock shotpin 2.1 and rotary locking handle 2.2, and both are affixed integral, and
The one end of rotary locking handle 2.2 is provided with A holes 2.3 and B holes 2.4, two axially bored lines angle in 90 ° on rotation lock shotpin 2.1.
Calculate when spacing between A holes 2.3 and B holes 2.4 is designed by manufactory and determine.
When the rod member of tractor mounnted frame is assembled, alignment needs the location hole between Assembly part, by rotation lock shotpin component 2
Penetrate in the pin-and-hole of rotating dog fixed seat 1, pressing locking handle 2.2 overcomes the spring force of rotation lock shotpin spring 5, makes close
Resilient key 3 at the A holes 2.3 of the one end of rotating dog fixed seat 1 is press-fited forward by correspondence elongated slot in rotating dog fixed seat 1, continuation.
At B holes 2.4 resilient key 3 near rotating dog fixed seat 1 when, rotary locking handle 2.2 cause B holes 2.4 at resilient key 3 with rotation
The long trough of pin fixed seat 1 is angled, you can realize connection and locking between tractor hanging bar.During dismounting, rotation lock
Only handle 2.2, make the resilient key at the A holes 2.3 of rotating dog fixed seat 1 after the elongated slot of rotating dog fixed seat 1, extract rotation
Twist lock shotpin component 2, you can complete dismounting.
