[0002] Vehicle repair is a general term for vehicle maintenance and repair. It means that for a malfunctioning vehicle, through technical means to troubleshoot, find out the cause of the malfunction, and take certain measures to eliminate the malfunction and restore it to a certain performance and safety standard. Vehicle repair includes major vehicle repair and minor vehicle repair. Major vehicle repair refers to the restorative repair that uses the method of repairing or replacing any parts of the vehicle (including basic parts) to restore the vehicle's sound technical condition and fully (or nearly fully) restore the vehicle's life. Minor vehicle repair refers to: the running repair that uses the method of replacing or repairing individual parts to ensure or restore the vehicle's working ability.

[0003] For the existing lever structure for vehicle repair, when replacing the spring pad in the vehicle buffer shock-absorbing spring, the spring of the vehicle has extremely high stiffness and elastic force, and it is impossible for manual operation to move the spring to contract and take out the spring pad. Therefore, a lever structure is adopted. However, there is no special lever structure for stably lifting the vehicle buffer spring. Maintenance personnel use a wrench and an auxiliary metal rod in combination to form a lever for use. It is necessary to manually support the stability of this combined structure and continuously press down to ensure the stability of the lifting height, which is not conducive to use during the repair process.

[0004] Therefore, in view of this, in view of the deficiencies of the existing structure, research and improvement are carried out, and a lever structure for vehicle repair is proposed. Content of the Utility Model

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1 - 3 shown, a lever structure for automobile repair includes an assembly seat 1. Above the inner side of the assembly seat 1, a shaft rod 2 is rotatably installed. On the left side of the surface of the shaft rod 2, a prying plate 3 is fixedly arranged. On the right side of the surface of the shaft rod 2, a force - applying rod 4 is fixedly installed. The length of the force - applying rod 4 is greater than that of the prying plate 3. A positioning mechanism 5 is arranged on the front side of the assembly seat 1.

[0023] By adopting the above - mentioned technical solution, the assembly seat 1, the shaft rod 2, the prying plate 3 and the force - applying rod 4 jointly form a complete lever structure for replacing the spring sleeve in automobile repair parts. When manually pressing down the force - applying rod 4 and using the lever arm greater than that of the prying plate 3, it can rotate around the center point of the shaft rod 2, and more easily lift the spring part of the automobile spring shock absorber, so as to replace the spring pad.

[0024] Furthermore, the positioning mechanism 5 includes a fixed block 502 fixedly installed in the middle of the front side of the surface of the assembly seat 1. A tension spring 503 is fixedly arranged on the lower surface of the fixed block 502.

[0025] Furthermore, the positioning mechanism 5 further includes a stop rod 504 fixedly installed at the lower end of the tension spring 503. A ratchet wheel 501 is slidably penetrated through the upper side of the stop rod 504 and arranged on the fixed block 502. The ratchet wheel 501 is fixedly connected to the front end of the shaft rod 2.

[0026] By adopting the above - mentioned technical solution, when the shaft rod 2 rotates, it will drive the ratchet wheel 501 to rotate. Using the inclined surface of the convex teeth of the ratchet wheel 501 itself, it will push the stop rod 504 downward. After the lever is pried to the required height, the stop rod 504 is inserted between the convex teeth of the ratchet wheel 501 by using the tension spring 503 to limit the ratchet wheel 501, so that the shaft rod 2 cannot rotate, and the elevated position of the prying plate 3 can be automatically fixed.

[0027] Furthermore, an elastic split ring 6 is fixedly installed on the lower surface of the assembly seat 1, and lugs 7 are fixedly installed on both sides of the opening part of the lower surface of the elastic split ring 6.

[0028] Furthermore, an adjusting bolt 8 is penetrated through the inside of the lug 7, and the adjusting bolt 8 is threadedly connected with the lug 7.

[0029] By adopting the above technical solution, the elastic split ring 6 can be wrapped on the bolt rivet under the automobile shock absorber spring rod. By screwing the adjusting bolt 8, the lugs 7 are closed, and the elastic split ring 6 is squeezed and locked towards the middle, so that the whole lever can be stably fixed without manual holding, and the assembly seat 1 is kept stable.

[0030] Furthermore, an extension rod 9 is arranged on the right side of the force application rod 4, and assembly plates 10 are fixedly arranged at the right end of the force application rod 4 and both the left and right ends of the extension rod 9.

[0031] Furthermore, screw holes 11 are opened at the four corners of the surface of the assembly plate 10, and fixing bolts 12 are threadedly connected to the inner surfaces of the screw holes 11.

[0032] By adopting the above technical solution, the extension rod 9 is spliced with the force application rod 4 by using the assembly plate 10 and fixed by screwing the fixing bolt 12 through the screw hole 11. The force application rod 4 can be extended according to the use requirements, so as to increase the length of the force arm and lift heavier automobile spare parts.

[0033] Working principle: When using this lever structure for vehicle repair, first of all, the elastic split ring 6 can be wrapped on the bolt rivet under the automobile shock absorber spring rod. By screwing the adjusting bolt 8, the lugs 7 are closed, and the elastic split ring 6 is squeezed and locked towards the middle, so that the whole lever can be stably fixed. At this time, the prying plate 3 is inserted under the spring of the automobile buffer spring rod. Then, the worker presses down the force application rod 4. With the shaft rod 2 as the axis point and a longer force arm, the automobile buffer spring can be easily lifted to replace the spring pad at the bottom of the spring. When the shaft rod 2 rotates, it will drive the ratchet 501 to rotate. By using the inclined surface of the convex teeth of the ratchet 501 itself, the shift lever 504 will be pushed down. After the lever is pried to the required height, the shift lever 504 is inserted between the convex teeth of the ratchet 501 by using the tension spring 503 to limit the ratchet 501, so that the shaft rod 2 cannot rotate, and the raised position of the prying plate 3 can be automatically fixed without manual continuous force application to fix the raised height position, liberating the worker's hands and making it more convenient to replace the automobile spring pad. Different vehicle models have different requirements for the elastic stiffness of the spring, which will lead to different elastic forces. By splicing the extension rod 9 with the force application rod 4 by using the assembly plate 10 and then fixing it by screwing the fixing bolt 12 through the screw hole 11, the force application rod 4 can be extended according to the use requirements, so as to increase the length of the force arm and lift a spring with a greater elastic stiffness. This is the working principle of this lever structure for vehicle repair.
