Description

Technical Field

[0001] The utility model belongs to the technical field of trailers, in particular to a frame structure for trailers. Background Art

[0002] A tow truck is a very common device used in car rescue and obstacle clearing. It ensures that a set of wheels of a car are lifted and then towed away by other vehicles. Tow trucks are also used in large multi-story parking lots to move the position of vehicles.

[0003] When using existing equipment, the trailer is prone to shaking and tipping over due to the uneven road surface during driving. At the same time, the center of gravity is easily shifted during loading, causing one end of the trailer to tilt. Therefore, we propose a frame structure for the trailer. Utility Model Content

[0004] The purpose of the utility model is to provide a frame structure for a trailer, which solves the problem that the trailer is easily shaken and easily overturned due to encountering uneven roads during driving, and the problem that one end of the trailer is easily tilted due to the center of gravity shifting during the loading process of the trailer, through a shock-absorbing mechanism and an extension mechanism.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] According to the above technical solution, by providing a slide groove inside the positioning tube, the rear baffle can be moved on the extension plate to change the center of gravity position of the frame through human intervention.

[0008] Furthermore, the outer wall of the trailer frame is fixedly connected to a plurality of connecting blocks, the outer walls of the plurality of connecting blocks are fixedly connected to limiting rods, the outer wall of the trailer frame is fixedly connected to a front baffle, and the outer wall of the trailer frame is fixedly connected to a plurality of fixing blocks.

[0009] Through the above technical solution, by fixing the limit rod on the connecting block, the movement of objects on the trailer can be restricted, and the design of being narrow at the bottom and wide at the top can avoid being scratched by low plants.

[0010] Furthermore, the inner wall of the connecting clamp is rotatably connected to a connecting rod, a positioning hole is opened on the inner wall of the connecting rod, and the inner wall of the connecting rod is rotatably connected to the outer wall of the connecting shaft.

[0011] According to the above technical solution, a positioning hole is provided in the center of the connecting rod and a connecting shaft is fixed thereto, so that the connecting rod can be moved up and down along the connecting shaft when necessary to keep the entire vehicle body stationary.

[0012] Furthermore, the outer wall of the connecting rod is fixedly connected to a plurality of axles, the outer walls of the plurality of axles are fixedly connected to rubber wheels, the outer walls of the axles are fixedly connected to a fixing seat, and the outer wall of the fixing seat is rotatably connected to a rotating shaft.

[0013] By adopting the above technical solution, by fixing the axles at both ends of the connecting rod and connecting them to the rubber wheels, it is possible to avoid affecting the use of the rubber wheels on the same side when the connecting rod is performing shock absorption work.

[0014] Furthermore, the outer wall of the rotating shaft is fixedly connected to the connecting rod 2, the outer wall of the connecting rod 2 is fixedly connected to the rotating shaft 2, the outer wall of the rotating shaft 2 is rotatably connected to the connecting block, the outer wall of the connecting block is fixedly connected to the fixing rod, and the outer wall of the fixing rod is fixedly connected to the outer wall of the rubber wheel.

[0015] With the above technical solution, the fixing seat is connected to the rubber wheel through the fixing rod, thereby avoiding the problem of the wheel falling off the axle when encountering severe bumps.

[0016] Furthermore, an extension plate is slidably connected to the inner wall of the positioning tube, a plurality of fixing holes are provided on both the extension plate and the inner wall of the positioning tube, and a clamping block is slidably connected to the inner wall of the fixing hole.

[0017] With the above technical solution, by providing a plurality of fixing holes on the positioning tube and the extension plate, the movement of the rear baffle can be restricted by moving the card block, thereby artificially controlling the center of gravity of the trailer.

[0018] Furthermore, a plurality of triangular plates are fixedly connected to the outer wall of the trailer frame, and a hydraulic rod is rotatably connected to the outer wall of the triangular plate.

[0019] According to the above technical solution, by connecting the hydraulic rod to the triangular plate, the position of the hydraulic rod can be easily fixed and the staff can use it conveniently.

[0020] Furthermore, a baffle is fixedly connected to the outer wall of the hydraulic rod, and a supporting foot is fixedly connected to the outer wall of the hydraulic rod.

[0021] Through the above technical solution, installing a baffle on the outward side of the hydraulic rod can effectively protect the hydraulic rod from damage caused by the outside.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model is provided with a connecting shaft, and the two ends of the connecting rod are respectively connected to the rubber wheels through the axle, and the center of the connecting rod is fixed to the connecting clamp by the connecting shaft and connected to the trailer frame. Therefore, when encountering a bumpy road surface, the connecting rod will lift the rubber wheel at one end and lower the other end with the connecting shaft as the center, so that the rubber wheel is fixed on the connecting rod and moves up and down with the connection point between the connecting shaft and the connecting rod as the center, preventing the trailer from shaking and easily rolling over due to encountering bumpy roads during driving.

[0024] 2. The utility model sets support feet, rotates multiple hydraulic rods, and makes the support feet fixed on the outer walls of the hydraulic rods contact the ground and provide a certain support to the trailer, thereby avoiding shaking and rollover that may occur when loading an empty trailer, and moves multiple blocks so that the tailgate can move along the outer wall of the extension plate, so that the center of gravity of the trailer is moved to a reasonable position and then the blocks are inserted back to limit the movement of the positioning tube. Then, the cargo can be loaded onto the frame, achieving the goal of changing the center of gravity by making the support feet connected by the hydraulic rods contact the ground and extending the rear side baffle, thereby preventing the problem of one end of the trailer tilting due to the center of gravity shifting during the trailer loading process.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
