In the figure: the support leg comprises an outer sleeve 1, an inner support leg 2, an adjusting screw rod 3, a nut top plate 4, a handle 5, a transmission sleeve 6, a fixing plate 7, a trailer 8, a limiting cap 9, a first lock pin hole 10, a second lock pin hole 11, a rotary hole 12, a support leg bracket 13 and a hanging joint 14.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a trailer landing leg mechanism, including square outer tube 1, adjusting screw 3 and the square inner leg 2 of slip setting in outer tube 1 inside, the one end fixedly connected with nut roof 4 of inner leg 2, the other end of inner leg 2 is the supporting foot, adjusting screw 3 wears in outer tube 1 and inner leg 2 and adjusts the upper and lower flexible volume of inner leg 2 with 4 screw-thread cooperations of nut roof, wherein, nut roof 4 is square, just so on the nut roof 4 of just making 2 direct actions of inner leg, the lifting surface area is little, stress is also little, in addition, adopt trapezoidal thread's adjusting screw 3 in this application, the technology is mature, the reliability is high, the wearability is high, a set of miscellaneous transmission reversing mechanism has been saved, adopt the direct transmission mechanism, torsion loss is little, and the structure is simple and convenient, also be convenient for processing. Specifically, the adjusting screw 3 comprises a threaded section and a non-threaded section, a limiting cap 9 is arranged between the threaded section and the non-threaded section, a fixing plate 7 is arranged on one side, away from the threaded section, of the limiting cap 9, the fixing plate 7 is fixedly connected with the outer sleeve 1 through a bolt, a transmission sleeve 6 is fixedly connected to the top of the adjusting screw 3, the transmission sleeve 6 is fixedly connected with the adjusting screw 3 through a bolt, the transmission sleeve 6 is in transmission fit with the handle 5, when the height of the inner supporting leg 2 needs to be adjusted, the handle 5 is inserted into the transmission sleeve 6 to rotate, the adjusting screw 3 rotates in place under the action of the fixing plate 7, but the nut top plate 4 cannot rotate in a square tube, the nut top plate 4 pushes against the inner supporting leg 2 to move up and down, so as to adjust the telescopic amount of the inner supporting leg 2, the adjusting screw 3 is additionally arranged on the basis of the traditional non-adjustable supporting leg, so that the structure has a height adjusting function, when no jack is arranged, rotate to with the ground contact with inner support leg 2, can directly act as the jack, convenient to use, simple structure, the practicality is high, has increased trailer 8's mobility, has solved and has realized trailer 8's light articulate and dismantle the problem under the condition that does not have the jack.
Preferably, the handle 5 in the embodiment is a T-shaped handle, the T-shaped handle has a long working distance, is easy to apply torque force, and is more practical than a common Z-shaped crank.
Further, outer tube 1 rotationally is connected with leg bracket 13 through gyration hole 12, and leg bracket 13 and outer tube 1 correspond and are equipped with first lockpin hole 10 and second lockpin hole 11, and during leg mechanism support state, fixed bolt penetrates and realizes the auto-lock in the first lockpin hole 10, prevents that leg mechanism from rocking, guarantees the stability of its support, and when leg mechanism withdrawed the state, fixed bolt realized the auto-lock in penetrating second lockpin hole 11, prevents that leg mechanism from dropping.
The working principle is as follows: as shown in fig. 2, when the trailer 8 needs to be separated from the tractor, the fixing bolt is firstly taken out from the second lock pin hole 11, then the handle 5 is inserted into the transmission sleeve 6, the adjusting screw rod 3 is driven to rotate by the torque force through the traditional sleeve, the adjusting screw rod 3 rotates in place under the action of the fixing plate 7, and the nut top plate 4 cannot rotate in the square tube, so that the nut top plate 4 extends downwards against the inner support leg 2 to reach the ground, the trailer 8 is supported, the trailer 8 is not supported on the tractor any more, and the lock pin for hanging can be conveniently pulled out at the moment, and the separation of the trailer 8 and the tractor is completed; as shown in fig. 2 and 3, when the trailer 8 needs to be articulated with the tractor, the handle 5 is inserted into the transmission sleeve 6 to rotate, the supporting legs are adjusted to a proper height, the hitching head 14 of the trailer 8 is matched with the height of the tractor, then the trailer 8 can be easily articulated with the tractor, after the hitching, the handle 5 retracts the inner supporting legs 2 to the shortest state, then the handle is folded in a rotating way, and finally the bolt in the first lock pin hole 10 is detached and penetrates into the second lock pin hole 11 to be fastened and self-locked, so that the hitching of the trailer 8 and the tractor is completed.
The structure is improved from the structure of the traditional simple supporting leg, the appearance size of the structure is basically consistent with that of the simple supporting leg, and the universality is high; the existing square tube section on the market is used as the inner tube and the outer tube of the supporting leg, and the shape of the raw material is used for limiting and stopping rotation, so that the design cost and the processing cost are reduced, and the design idea is ingenious; the power direct transmission mechanism is adopted, so that the torsion loss is small, the structure is simple, and the square tube is suitable for being arranged in a narrow space inside the square tube; the extension and the shortening of the supporting leg are realized through the transmission of the designed simple trapezoidal thread, and the device is simple, reliable and self-locking; the trailer can be easily hung in hanging seats with different heights and can be hung on different tractors at any time and any place, and the universality of hanging the trailer 8 and different tractors is greatly improved.
