The role of the bracket for car maintenance

Background technique:

A car is generally composed of an engine, a chassis, a body, and electrical equipment. China is a big automobile country, and it has been increasing year by year. The problem of vehicle maintenance comes with many vehicles. Due to the large volume and weight of automobile engine, chassis, body and other components, it is not easy to handle, so it is impossible to carry out a full range of vehicle For maintenance and maintenance, if you manually carry these things, on the one hand, it will increase the working time of the maintenance staff, reduce the work efficiency of the maintenance staff, and on the other hand, it will pose a certain threat to the personal safety of the maintenance staff.

Technical realization elements:

The main purpose of the utility model is to provide a convenient and safe and reliable automobile maintenance bracket.

In order to achieve the above purpose, the technical solution adopted by the present utility model is: a bracket for automobile maintenance, comprising a left bracket, a right bracket and a cross beam, the left bracket and the right bracket are spaced apart, and the cross beam is fixed at On the left bracket and the right bracket, left and right through installation cavities are arranged in the beam, a pulley set is arranged in the installation cavity, and a hand hoist is arranged on the right bracket. A hoisting hook is connected to the wire rope of the hand hoist after passing the pulley set. Two universal wheels are provided at the lower end of the right bracket, and two support feet are provided at the lower end of the left bracket. The lower end of the bracket is further provided with a downwardly-opening groove, the groove is located between the two supporting feet, and the automobile maintenance bracket further includes a trolley vehicle, and the trolley vehicle includes a trolley and a In the base fixed by the tie rod, rollers are respectively provided at both ends of the base, and the base is provided with a connecting pin matching the groove, and the connecting pin is inserted into the groove. , Press down Of said rod, said connecting pin is moved upward from the top of the support leg to clear the ground.

Preferably, trapezoidal clamping grooves are provided on the upper end surfaces of the left bracket and the right bracket, and the left and right ends of the lower end surface of the beam are respectively provided with clamping blocks matching the trapezoidal clamping grooves. The clamping blocks are located one-to-one in the trapezoidal card slot. The setting of the trapezoidal card slot and the block is beneficial to the firm combination of the beam with the left and right brackets, and it is not easy to fall apart. The setting of the trapezoidal card slot can limit the axial movement of the beam.

Preferably, the pulley set is composed of a first pulley, a second pulley, and a third pulley. The first pulley is rotatably disposed on the left side of the installation cavity, and the third pulley is rotatably disposed on On the right side of the mounting cavity, the second pulley is located between the first pulley and the third pulley. The arrangement of the first pulley, the second pulley, and the third pulley can change the direction of the force, thereby facilitating the user to adjust the operation direction.

Preferably, the left bracket and the right bracket are respectively provided with a storage slot. The storage slot is convenient for storing idle tools, so it is not easy to lose.

Preferably, the lower part of the connecting pin is provided with an external thread, the base is provided with a threaded hole that cooperates with the external thread, and the connecting pin is screwed into the threaded hole. In this structure, the connection pin is screwed into the threaded hole, which is convenient for adjusting the depth of the connection pin in the threaded hole, so that when the connection pin extends into the groove, the support foot can be kept away from the ground.

Preferably, the upper part of the connecting pin is a ball-shaped structure. In this structure, the upper part of the connecting pin is a ball-shaped structure, on the one hand, it enters the groove more smoothly, on the other hand, it is convenient for the connecting pin to rotate in the groove, and it is convenient to adjust the steering of the roller, so as to control the direction of the bracket for automobile maintenance.

Preferably, the tie rod has a T-shaped structure. In this structure, it is convenient to pull the bracket for automobile maintenance.

Preferably, the left bracket and the right bracket are both A-type brackets. In this structure, the A-type bracket structure is stable.

Compared with the prior art, the utility model has the advantages that the setting of the pulley unit can adjust the direction of the force and is more flexible; the setting of the hand hoist can adjust the height of the lifting hook, so that heavier parts of the car can be hoisted while avoiding The weight to be lifted comes into direct contact with the staff, which improves safety; the setting of the universal wheel can adjust the rotation direction of the right bracket to facilitate the movement of the whole; the connecting pin of the trolley is inserted into the groove, and when the lever is pressed down, On the one hand, the support foot is lifted to separate it from the ground. On the other hand, the car maintenance bracket can be moved by pulling the lever, which is convenient to operate. By turning the lever to make the lever face different directions, it is convenient to adjust the bracket of the car maintenance bracket. Trend; the utility model is convenient to operate and safe and reliable.
