Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle tire repair tools, specifically relating to a lifting device for vehicle tire replacement and repair. Background Technology

[0002] With the improvement of the current automotive industry, the number of cars on the road is increasing day by day. A car includes components such as chassis, engine, and tires. Among them, tires play a very important role in the driving of a car. When a car tire is damaged and needs to be repaired, a lift is needed to lift the entire vehicle or one side of it.

[0003] Existing lifts have a fixed overall structure during use, meaning they cannot be folded. They still take up a lot of space when not in use, and it is not convenient to precisely control the lifting operation when in use, which limits their use. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting device for vehicle tire replacement and maintenance, in order to solve the problems mentioned in the background art, that the existing lifting device has a fixed overall structure during use, that is, it cannot be folded, it still occupies a lot of space when not in use, and it is not convenient to accurately control the lifting operation when in use, thus having certain limitations in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for vehicle tire replacement and maintenance, comprising a movable base, universal wheels installed at the four corners of the lower surface of the movable base, two fixing blocks fixedly installed on the upper surface of the movable base, a column housing rotatably installed between the two fixing blocks, a locking plate fixedly installed at the lower side of the column housing, two handrails fixedly installed on the upper surface of the locking plate, a power source provided on the side of the column housing, a bevel gear one and a threaded rod rotatably installed inside the column housing for use with the power source, a bevel gear two meshing with the bevel gear one fixedly installed on the outer surface of the bottom end of the threaded rod, a threaded plate threadedly installed on the outer surface of the threaded rod, a mounting seat fixedly installed on the side of the threaded plate, and a lifting rod hanging on the mounting seat.

[0006] The above solution utilizes a movable base, a column housing, a threaded plate, and a lifting rod. The movable base is moved to multiple positions via casters, while the column housing, with the help of a fixing block, can rotate. During use, the column housing is rotated to a vertical position and unfolded. The threaded rod then helps raise and lower the lifting rod, effectively lifting the vehicle body at the tire level. After use, it is rotated to a horizontal position and folded away. The folding structure is simple, easy to operate, and avoids occupying excessive space. A locking rod and locking nut, along with a positioning block and a positioning pin, are used to achieve the folding and unfolding of the column housing and its locking operation after folding. The locking structure is simple, easy to operate, and provides good stability.

[0007] In a preferred embodiment, a mounting base is fixedly installed on the upper surface of the movable base, and a locking rod is rotatably installed inside the mounting base. The outer surface of the locking rod has threads and a locking nut is threaded onto the locking plate. A slot is provided on the locking plate, and the locking rod cooperates with the slot.

[0008] Using the above solution, the mounting base is used in conjunction with the rotating locking rod and locking nut. When the column housing is rotated and unfolded, the locking rod can be rotated and inserted into the slot. Then, the locking nut can be tightened to fix the locking plate, thereby achieving the locking and fixing of the column housing. The locking structure is simple and easy to operate.

[0009] In a preferred embodiment, a tool box is fixedly installed at the top of the handrail, and the tool box is fixedly installed on the side of the column housing.

[0010] By adopting the above solution, the toolbox is designed to facilitate the storage and use of tools, thereby improving ease of use.

[0011] In a preferred embodiment, a support shaft is fixedly installed at the top end of the threaded rod, and the support shaft is rotatably installed on the inner wall of the column housing.

[0012] By adopting the above scheme, the support shaft can support the threaded rod, which makes the threaded rod more stable during rotation and less prone to tilting and wobbling.

[0013] In a preferred embodiment, a plurality of guide bars are fixedly installed on the inner wall of the column housing, and a plurality of guide grooves are opened on the side of the threaded plate, with the guide bars sliding on the inner wall of the guide grooves.

[0014] Using the above scheme, when the threaded rod rotates and drives the threaded plate to move, the threaded plate will slide on the surface of the guide bar through the guide groove. In this way, the stable sliding of the threaded plate can be ensured by the cooperation of the guide bar and the guide groove.

[0015] In a preferred embodiment, a positioning block is fixedly installed on the side of the column housing. The positioning block and the locking plate are located on opposite sides of the column housing. A positioning pin is inserted into the positioning block, and a positioning groove for the positioning pin to be inserted is provided on the inner wall of the movable base.

[0016] Using the above solution, when the column housing is rotated and folded to be level with the movable base, the positioning pin can pass through the positioning block and be inserted into the guide positioning groove, which can realize the locking operation after folding, making the operation convenient.

[0017] In a preferred embodiment, a locking rod is vertically fixedly installed on the lifting rod, and a hanging rod is horizontally fixedly installed on the outer surface of the locking rod. A locking groove for the locking rod to be inserted is vertically opened on the hanging base, and a hanging groove for the hanging rod to be inserted is horizontally opened on the hanging base.

[0018] Using the above method, the mounting rod is inserted into the mounting slot, and the locking rod is locked into the locking slot, realizing convenient installation of the lifting rod and facilitating disassembly and assembly.

[0019] In a preferred embodiment, a rubber sleeve is attached to the outer surface of the lifting rod.

[0020] By adopting the above solution, the rubber sleeve can provide an anti-slip effect and prevent the lift rod from damaging the vehicle skirt when it is raised.

[0021] In a preferred embodiment, the power source is specifically a fixed motor, which is fixedly installed on the side of the column housing, and the output shaft of the fixed motor is fixedly connected to a bevel gear.

[0022] The above solution utilizes a fixed motor as a power source in conjunction with a bevel gear, making it convenient to carry and use.

[0023] In a preferred embodiment, the power source may be a handheld motor, the output shaft of which is fixedly fitted with a plug, and a slot for inserting the plug is provided at the center of the shaft of the bevel gear.

[0024] The above solution utilizes a handheld motor that engages with a bevel gear via a plug, and the handheld motor can be disassembled and carried on one's person, ensuring that the machine is dedicated to a specific purpose and preventing unqualified personnel from operating it arbitrarily.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This vehicle tire replacement and maintenance lifting device uses a movable base, a column housing, a threaded plate, and a lifting rod. The movable base can be moved to multiple positions via casters, and the column housing can be rotated with a fixing block. When in use, the column housing can be rotated to a vertical position and unfolded. The threaded rod then raises and lowers the lifting rod to lift the vehicle body at the tire position. After use, it can be rotated to a horizontal position and folded away. The folding structure is simple, easy to operate, and avoids taking up too much space.

[0027] The lifting device for tire replacement and maintenance of this vehicle uses a locking rod and locking nut in conjunction with a positioning block and positioning pin to achieve the folding and opening of the column housing and the locking operation after folding and retracting. The locking structure is simple, easy to operate, and has good stability. Attached Figure Description
