Description
Technical field
The application is related to trailer technical field, more particularly to a kind of trailer preceding lifting rotation supporting leg.
Background technology
There is quite a few trailer to use central axle pattern, lifting landing leg need to be set at hitch frame, in main extension separation,
Supporting leg will be in bearing state, it is ensured that the balance of trailer, and in main extension connection walking, supporting leg will pack up certain height, it is ensured that
Vehicle passes through property.Traditional lifting landing leg uses screw structure, sometimes for guarantee terrain clearance, and band, which is unfolded, below supporting leg is
System, but the shortcoming of this screw structure is that operation handle power is too big, can be shaken when unloaded, shake gruelling when heavily loaded, rapid wear
It is bad.
The content of the invention
The purpose of this utility model is to avoid weak point of the prior art, and there is provided a kind of simple in construction, user
Just the preceding lifting rotation supporting leg suitable for trailer.
In order to solve the above problems, the technical solution of the utility model is：Lifting rotation supporting leg before a kind of trailer, its group
Into including rotary lifter, bearing block and supporting leg, it is characterised in that：The supporting leg is flexibly connected by bearing block with chassis, institute
Category bearing block be fixedly mounted on chassis, the rotary lifter by chain with being fixedly connected below supporting leg, the rotation
Lift is fixedly mounted in the middle part of chassis.
The branch midleg, which is provided with below locking hole, the chassis, is provided with vertical lockable mechanism, described vertical
Lockable mechanism is respectively symmetrically located at the lower section and top on chassis with bearing block.
Rotary locking mechanism is also equipped with below the chassis, the rotary locking mechanism is located at supporting leg and rotation and lifting
Between machine.
The bottom of the supporting leg is provided with leg.
The leg can be platen surface leg, or universal wheel leg.
The beneficial effects of the utility model are：
1st, lifting landing leg is designed to rotatably by the utility model, the back rotation after supporting leg is packed up, it is ensured that it is enough from
Ground gap, it is ensured that vehicle passes through property.
2nd, leg of the utility model below supporting leg has two kinds can change at any time, and one kind is platen surface leg, for soft
Support during road surface, another is universal wheel leg, is used at hard pavement, hitch frame can be moved left and right, facilitates main trailer
Connection.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：Bearing block 1, vertical lockable mechanism 2, rotary lifter 3, rotary locking mechanism 4, chain 5, supporting leg 6, flat board
Face leg 7, chassis 8.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
In Fig. 1, a kind of lifting rotation supporting leg before trailer, its composition includes rotary lifter 3, bearing block 1 and supporting leg 6,
It is characterized in that：The supporting leg 6 is flexibly connected by bearing block 1 with chassis 8, and affiliated bearing block 1 is fixedly mounted on chassis 8,
The rotary lifter 3 is fixedly connected by chain 5 with the lower section of supporting leg 6, and the rotary lifter 3 is fixedly mounted on chassis 8
Middle part.
The middle part of the supporting leg 6 is provided with locking hole, and the lower section on the chassis 8 is provided with vertical lockable mechanism 2, described to hang down
Straight lockable mechanism 2 is respectively symmetrically located at the lower section and top on chassis 8 with bearing block 1.
The lower section on the chassis 8 is also equipped with rotary locking mechanism 4, and the rotary locking mechanism 4 is located at supporting leg 6 and rotation
Between lift 3.
The bottom of the supporting leg 6 is provided with leg.
The leg can be platen surface leg 7, or universal wheel leg.
When trailer, which is parked, needs support, rotary locking mechanism 4 is first extracted, now supporting leg 6 is no longer secured on chassis 8,
First rotate counterclockwise rotary lifter 3, supporting leg 6 is put to plumbness by heeling condition, plugs vertical lockable mechanism 2, now
Supporting leg 6 is fixedly connected with chassis 8, it is ensured that supporting leg 6 will not be tilted.Lifting handle is operated again, it is complete by the supporting descending ground of supporting leg 6
Into support operation.When trailer traveling needs to pack up supporting leg 6, lifting handle is operated, supporting leg 6 is packed up, then extract vertical locking
Mechanism 2, now supporting leg 6 be no longer fixedly connected with chassis 8, turn clockwise rotary lifter 3, and rotary lifter 3 passes through chain 5
Slowly by the pull-up of supporting leg 6, until at rotary locking mechanism 2, now plugging rotary locking mechanism 4, now supporting leg 6 is fixed on chassis
On 8, so as to both ensure that the road clearance of supporting leg 6, it also ensure that supporting leg 6 will not fall off in the process of moving.The leg of supporting leg 6
There are two kinds can change at any time, one kind is platen surface leg 7, support during for Terrain surface, and another is universal wheel leg, hard
Used during road surface, hitch frame can be moved left and right, facilitate the connection of main trailer.
