Description

TECHNICAL FIELD

[0001] The utility model relates to the field of trailer parts, in particular to a semitrailer outrigger. BACKGROUND

[0002] In the design and application of the conventional semitrailer outrigger, the handle as the key operating part for controlling the lifting of the outrigger, its stability and controllability have been the focus of the industry. In the past, the handle of the semitrailer outrigger is usually connected to the outrigger body only by a simple connecting structure, lacking effective positioning and limiting mechanism.

[0003] When the operator rotates the handle, the handle is prone to excessive rotation. Once the handle is excessively rotated or exceeds the normal operating area, the key components such as gears and transmission rods inside the outrigger will bear additional impact force and torsion. Over a long period of time, these components are not only prone to wear and deformation, but even may be broken, thereby directly affecting the normal use of the outrigger and reducing the overall safety and reliability of the semitrailer. SUMMARY

[0004] The utility model aims at providing a semitrailer outrigger to solve the problem of lack of positioning mechanism of the conventional handle in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a semitrailer outrigger, comprising an outrigger with a transmission assembly and a handle, a bracket composed of a hanger and a side frame is fixedly installed on one side of the transmission assembly, one end of the side frame is provided with a positioning groove for accommodating the handle, and a pull rod is slidingly installed on the side wall of the side frame through an elastic member, so that the pull rod cooperates with the positioning groove to radially constrain the handle.

[0006] Preferably, both ends of the hanger are fixedly connected to the outrigger by bolts, one end of the side frame away from the positioning groove is provided with an L-shaped structure, and the L-shaped structure end of the side frame is fixedly connected to the hanger.

[0007] Preferably, the elastic member is a spring sleeved on the pull rod, both ends of the pull rod are respectively threadedly connected to a pair of nuts, and both ends of the spring are respectively in contact with the side frame and the nut.

[0008] Preferably, the pull rod is provided with a pair of arc-shaped segments for supporting the handle, and the pair of arc-shaped segments are transitioned by a U-shaped segment.

[0009] Preferably, the positioning groove is of an arc-shaped structure.

[0010] Preferably, a trapezoidal groove is arranged at the central position of the hanger.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] The utility model discloses a positioning support of rocking handle is formed by side frame, pull rod, positioning groove and spring cooperation, and the setting of pull rod, positioning groove limits the movement range of rocking handle, prevents its excessive rotation or exceeds normal operating area, reduces the risk of causing the damage of support leg or relevant part because of the operation mistake.

[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0019] Please refer to Figures 1-4The utility model provides a technical scheme: a semitrailer support leg, including the support leg 1 with transmission assembly 3 and the handle 4 of shaking, transmission assembly 3, the handle 4 of shaking are all prior art, principle does not repeat here, the support leg 1 is located transmission assembly 3 one side fixed mounting is equipped with the support frame of the assembly of hanger 2, side frame 5, the both ends of hanger 2 are fixedly connected through bolt and support leg 1, the central position of hanger 2 is equipped with trapezoidal groove, trapezoidal groove is set as the pivot of transmission assembly 3 provides the accommodation space, one end of side frame 5 is equipped with the positioning groove 7 for accommodating the handle 4 of shaking, positioning groove 7 is arc structure, the advantage that such setting is, arc groove 7 can accurately match the handle 4 of shaking movement track, makes the handle 4 in the whole operation all can be in the smooth movement in the groove, avoids the jamming because of movement limitation, improves the operation smoothness, the end of side frame 5 away from positioning groove 7 is set as L shape structure, the L shape structure end of side frame 5 is fixedly connected with hanger 2, the side wall of side frame 5 is slidably installed with pull rod 6 through elastic component, pull rod 6 is equipped with a pair of arc segment 9 for supporting the handle 4 of shaking, a pair of arc segment 9 is transitioned through U segment 10 between, so that pull rod 6 cooperates positioning groove 7 to do radial constraint to the handle 4 of shaking, elastic component is spring 8 of the sleeve on pull rod 6, a pair of nuts is respectively screwed on the both ends of pull rod 6, the both ends of spring 8 are respectively in contact with side frame 5, nut, 10 is the inclined structure of expansion, the advantage that such setting is to match 4 into 7 in the movement track, makes 6 and 8 cooperate radial tension to 4, radial spring tension can provide certain assistive force component in the 4 rotation direction, helps the operator to rotate 4 more easily, reduces physical exertion.
