Description

Technical Field

[0001] The utility model belongs to the technical field of automobile chassis maintenance, and in particular relates to an outdoor supporting device for automobile chassis maintenance. Background Art

[0002] A jacking device is a light and small lifting device that uses a rigid jacking piece to push heavy objects through a small stroke of the top support seat or the bottom support claw. At present, the main defects of the jacking device are as follows:

[0003] Since the traditional jacking device supports the main beam of the automobile, it is easy for the entire device to be offset and misaligned with the main beam during jacking. The traditional device cannot more effectively prevent the misalignment of the jacking device. When the main beam is misaligned, it will directly cause damage to the automobile chassis and cause safety hazards to maintenance personnel. Utility Model Content

[0004] The purpose of the utility model is to provide an outdoor supporting device for automobile chassis maintenance, aiming to solve the problem that the prior art cannot more effectively prevent the misalignment of the supporting device, which directly leads to damage to the automobile chassis and poses a safety hazard to maintenance personnel after the main beam is misaligned.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A user's outdoor support device for automobile chassis maintenance comprises a support top seat, both ends of the support top seat are fixedly installed with protective plates, one side of the two protective plates is rotatably connected to a main rotating shaft, two protective rods are fixedly installed on the outer side of the main rotating shaft, the bottom ends of the two protective rods are slidably connected to a protective frame, a first electric telescopic rod is fixedly installed on the inner wall of the bottom end of the protective rod, and the telescopic end of the first electric telescopic rod is fixedly connected to the top two ends of the protective frame.

[0007] As a preferred embodiment of the utility model, the support top seat is internally rotatably connected with two driving rods, the outer sides of the two driving rods are fixedly installed with driving gears, the outer sides of the driving gears are meshed with driving racks, and second electric telescopic rods are fixedly installed at both ends of the driving racks, and the fixed ends of the second electric telescopic rods are fixedly connected to the inner side wall of the support top seat.

[0008] As a preferred embodiment of the utility model, one end of the inner part of the protective plate is rotatably connected to a driven rod, and the outer sides of the driven rod and the main shaft are fixedly mounted with linkage gears.

[0009] As a preferred embodiment of the utility model, linkage wheels are fixedly mounted on the outer sides of the driven rod and the driving rod, and belts are sleeved on the outer sides of the linkage wheels.

[0010] As a preferred embodiment of the utility model, a support base is provided at the bottom of the support top seat, and a plurality of lifting rods are rotatably connected between the support base and the support top seat.

[0011] As a preferred embodiment of the utility model, one end of the plurality of lifting rods is rotatably connected to an intermediate shaft, and the inner side walls of two intermediate shafts are threadedly connected to lifting screws.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1) By setting up the protective plates on both sides of the support top seat, the applicable range of the contact between the overall support device and the main beam can be increased. When the main beam and the support top seat are misaligned, the protective plates can prevent the main beam from separating from the overall device. By setting up the protective frames and protective rods that are deployed from the inside of the protective plates, the supporting effect of the protective plates can be further increased, thereby increasing the force-bearing area and range of the overall device.

[0014] 2) The drive rack can more easily drive the drive rod to rotate inside the support top seat, thereby making it easier for the protective rod and the protective frame to unfold outside the protective plate and provide support for contact with the ground. BRIEF DESCRIPTION OF THE DRAWINGS
