[0002] Single wheel lift for car repair is one of the commonly used methods in the process of car repair and maintenance. It refers to lifting one wheel of the car to an appropriate height for inspection, repair and replacement of parts. It is usually driven by a hydraulic system. The hydraulic pump generates force through the pressure of hydraulic oil, pushing the hydraulic oil into the hydraulic cylinder, thereby moving the piston of the hydraulic cylinder upward and lifting the car wheel.

[0003] In traditional automobile maintenance, a single-wheel lifting is usually performed by driving a vertically arranged wheel axle through a hydraulic lifting device. The operator sets the center positioning hole of the wheel on the outside of the wheel axle, then performs lifting control and repairs the wheel. However, this method is difficult to position wheels of different sizes during use. When the size of the wheel increases, the thickness of the wheel body will increase accordingly. At this time, the positioning stability of a single wheel axle with a fixed length is poor, which makes the wheel easy to fall or shake during the lifting process. Considering the safety of maintenance, a single-wheel lifting device for automobile maintenance is proposed to solve the above problem. Utility Model Content

[0008] As a further improvement of the present invention, a lifting plate is fixedly provided on the upper end surface of the mounting plate, and the lifting plate is bent and arranged in an L-shape with the mounting plate.

[0009] As a further improvement of the utility model, a hydraulic lift is vertically mounted on the upper surface of the vertical plate, and the output end of the hydraulic lift extends vertically and is connected to the lifting plate.

[0010] As a further improvement of the present invention, the fixed wheel assembly further comprises two positioning screw plates arranged on the clamping seat, and both positioning screw plates are provided with an optical axis, and the optical axis is vertically arranged and passes through the upper clamping plate.

[0011] As a further improvement of the utility model, the upper end of the threaded screw passes through the clamping seat, extends to the outside and is connected to an adjusting shaft, and a rubber gasket is sleeved on the outside of the adjusting shaft.

[0021] Example

[0022] Depend on Figure 1-4 Provided is a single-wheel lifting device for automobile maintenance, comprising a bottom plate 1 and a vertical plate 2;

[0023] The vertical plate 2 is L-shaped and vertically arranged on the upper end surface of the bottom plate 1. Two linear guide rails 3 are vertically parallel to one side of the vertical plate 2. Slide blocks 4 are slidably arranged on the two linear guide rails 3. The adjacent slide blocks 4 on the same side form a group and the two groups of slide blocks 4 are jointly equipped with a mounting plate 5. A fixed wheel assembly 7 is assembled on one side of the mounting plate 5.

[0024] The fixed wheel assembly 7 includes a positioning platform 71 arranged on one side of the mounting plate 5, and a clamping seat 72 is fixedly provided on one side of the positioning platform 71. The clamping seat 72 is provided with a rectangular groove, and a threaded screw 75 is vertically rotated in the rectangular groove. An upper clamping plate 77 is slidably engaged with the threaded screw 75 on the outside.

[0025] In this embodiment, through the movement coordination of the components in the fixed wheel assembly 7, the center hole of the automobile wheel can be penetrated and positioned in actual use, thereby achieving accurate positioning of the automobile wheel. When repairing a single wheel of an automobile, the wheel can be firmly fixed on the fixed wheel assembly 7 to ensure that the position of the wheel is accurate. At the same time, the fixed wheel assembly 7 with clamping movement can also adapt to the clamping of wheels of different thicknesses. The overall application range is wide. Through the cooperation of the fixed wheel assembly 7 and the lifting device, the wheel can be easily lifted and lowered. The operator can use the lifting device to lift the fixed wheel assembly 7 and the wheel to an appropriate height for maintenance and inspection. Such a design simplifies the operating process, improves work efficiency, and has higher overall safety.

[0026] Specifically, refer to Figure 2-4 A lifting plate 51 is fixedly provided on the upper end surface of the mounting plate 5 , and the lifting plate 51 is bent and arranged in an L-shape with the mounting plate 5 .

[0027] In this embodiment, in actual use, the provided lifting plate 51 can be used to connect the lifting device, and cooperate with the provided slider 4 and the sliding cooperation of the linear guide 3. When the lifting device drives the lifting plate 51 to move, the provided mounting plate 5 can follow it to move on the linear guide 3. At the same time, the provided slider 4 can ensure that the mounting plate 5 moves in a straight line and ensure the movement stability of the mounting plate 5.

[0028] Specifically, refer to Figure 1-2 A hydraulic lift 6 is vertically mounted on the upper end surface of the vertical plate 2 , and an output end of the hydraulic lift 6 extends vertically and is connected to the lifting plate 51 .

[0029] In this embodiment, during use, the operator gives the hydraulic lift 6 an output air pressure value so that the hydraulic lift 6 can control the radial extension of its output end, thereby controlling the movement of the lifting plate 51, thereby realizing the lifting control of the mounting plate 5, and then realizing the lifting control of the fixed wheel assembly 7 assembled on one side of the mounting plate 5.

[0030] Specifically, refer to Figure 3-4 The fixed wheel assembly 7 also includes two positioning screw plates 73 arranged on the clamping seat 72, and the two positioning screw plates 73 are both provided with an optical axis 74, which is vertically arranged and passes through the upper clamping plate 77.

[0031] In this embodiment, by setting the optical axis 74 and the positioning screw plate 73, during use, when the operator rotates the threaded screw 75, the optical axis 74 limits the positions of the upper clamping plate 77 on both sides, so that the upper clamping plate 77 can move up and down in a vertical linear manner in the clamping seat 72.

[0032] Specifically, refer to Figure 3-4 The upper end of the threaded screw 75 passes through the clamping seat 72 and extends to the outside and is connected to an adjusting shaft 76. The outer side of the adjusting shaft 76 is sleeved with a rubber gasket.

[0033] In this embodiment, during use, the operator rotates the adjustment shaft 76, and through the rotational connection between the adjustment shaft 76 and the threaded screw 75, the set threaded screw 75 follows the rotation. When the threaded screw 75 rotates, the linear limit of the optical axis 74 on both sides makes the upper clamping plate 77 engaged on the outside of the threaded screw 75 can be raised and lowered in a linear manner along the travel range of the threaded screw 75. The rubber gasket arranged on the outside of the adjustment shaft 76 can be used to isolate and protect the operator's hands and improve the comfort when rotating the adjustment shaft 76.

[0034] Specifically, refer to Figure 3-4 A lower clamping plate 78 is vertically provided on one side of the positioning platform 71. The lower clamping plate 78 is parallel to the lower end surface of the upper clamping plate 77. The opposite surfaces of the upper clamping plate 77 and the lower clamping plate 78 are both provided with positioning shafts 79.

[0035] In the present embodiment, in actual use, the user rotates the adjustment shaft 76 so that the upper clamping plate 77 engaged on the threaded screw 75 can be moved downward until the two positioning shafts 79 are tightly against each other. The user sets the center positioning hole of the automobile wheel on the outside of the positioning shaft 79 located on the lower clamping plate 78. At this time, the center hole of the automobile wheel can be penetrated and positioned by the two oppositely clamped positioning shafts 79. In the design, considering the different diameters of the center holes of different automobile wheels, the positioning shaft 79 can be assembled on the upper clamping plate 77 and the lower clamping plate 78 by bolts. Then, when encountering wheels with center holes of different diameters, the positioning shafts 79 of different diameters can be replaced for clamping, thereby further improving the positioning use range of the automobile wheel.

[0036] In this embodiment, the positioning shaft 79 provided by the clamp cooperates with the lifting movement provided by the hydraulic lift 6 to provide a safe working environment when repairing a single wheel of an automobile; the operator can repair a single wheel of an automobile under stable and controllable conditions, reducing the risk of accidents.

[0037] The utility model of the automobile single wheel lifting device for automobile maintenance:

[0038] Step 1: In use, the operator rotates and adjusts the rotating shaft 76, and adjusts the rotation connection between the rotating shaft 76 and the threaded screw 75, so that the threaded screw 75 is rotated accordingly. When the threaded screw 75 is rotating, the upper clamping plate 77 engaged with the outside of the threaded screw 75 can be lifted and lowered in a straight line along the travel range of the threaded screw 75 through the linear limit of the optical axis 74 on both sides. The operator controls the distance between the threaded screw 75 and the upper clamping plate 77 to separate them, and at this time, the vehicle wheel to be lifted and lowered can be placed between the two positioning shafts 79;

[0039] Step 2: When the center hole of the automobile wheel is placed on the two positioning shafts 79 and sleeved on the positioning shaft 79 at the bottom, the user rotates the adjusting shaft 76 in the opposite direction again, so that the upper clamping plate 77 moves down until the two positioning shafts 79 are tightly against each other. At this time, the center of the automobile wheel can be positioned by the two oppositely clamped positioning shafts 79;

[0040] Step 3: After the two positioning shafts 79 are clamped and the vehicle wheels are positioned, the user connects the hydraulic lift 6 to an external air source and gives the hydraulic lift 6 an output air pressure value, so that the set hydraulic lift 6 can control the radial extension of its output end, and then control the movement of the lifting plate 51, thereby realizing the lifting control of the mounting plate 5, and then realizing the lifting control of the fixed wheel assembly 7 assembled on one side of the mounting plate 5, and completing the lifting control of the vehicle wheel positioned on the fixed wheel assembly 7.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
