Description

Technical Field

[0001] This utility model relates to the field of automotive repair technology, specifically to a rear beam moving tool for automotive repair. Background Technology

[0002] In the overall structure of a car, the rear beam plays a crucial role as a key load-bearing component of the vehicle body. It not only needs to withstand various vertical loads on the rear of the vehicle during driving, such as the weight of passengers and cargo, but also needs to cope with dynamic forces from different directions, such as the inertial forces generated during acceleration, braking, and cornering. The rear beam is usually made of high-strength steel and has a complex geometry and specific structural design to ensure that it can effectively distribute and transmit these forces and maintain the stability and rigidity of the vehicle body.

[0003] However, during vehicle use, the rear beam may be damaged for various reasons, with traffic accidents being one of the most significant factors. Whether it's a minor collision or a severe impact, the rear beam can deform, such as bending, twisting, or denting. Once the rear beam is damaged, the vehicle's driving performance will be significantly affected, including decreased handling, reduced driving stability, and uneven tire wear. In severe cases, it can even endanger driving safety. Therefore, in order to efficiently and accurately repair damaged rear beams and restore the vehicle's original performance and safety, a beam straightening machine has emerged and become an indispensable key tool in the automotive repair field.

[0004] However, some existing beam straightening machines lack flexibility in adjusting the chain angle, making it difficult to meet the various complex deformation conditions of the rear beam of a car. The impact force that the rear beam of a car is subjected to in an accident is often multi-directional and irregular, resulting in a wide variety of deformation directions and angles. However, some beam straightening machines usually use a fixed chain connection method, which limits the range of chain angle adjustment and makes it difficult to make flexible adjustments according to the actual deformation of the rear beam. This may result in the inaccurate application of corrective force during the straightening process, affecting the straightening effect, repair quality, and vehicle safety. Utility Model Content

[0005] The purpose of this utility model is to provide a rear beam moving tool for automobile repair, which can adjust the angle of the fixing frame so that the chain inside the cavity can better adapt to various complex deformations of the automobile rear beam. It also prevents the chain from breaking accidentally during use and causing it to fly everywhere, thus avoiding injury to maintenance personnel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rear beam moving tool for automobile repair, comprising a beam straightening instrument body and a pull tower sliding on its inner wall, and further comprising: A chain is provided on the surface of the tower. The surface of the tower is provided with a mounting block. A fixing block is fixedly connected to one side of the mounting block, and a sliding block is slidably connected to one side of the mounting block. A rotating block is provided on one side of the fixing block, and a fixing frame is fixedly connected to one side of the rotating block. A limiting mechanism is installed in the inner cavity of the fixed block to limit the angle of the rotating block. The surface of the rotating block is provided with a pointer, the surface of the fixed block is provided with scale lines, and mounting shells are fixedly connected to both sides of the rotating block. The inner cavity of the mounting shell is provided with a winding mechanism.

[0007] Preferably, the limiting mechanism includes a bolt slidably connected to the inner wall of the fixed block, a nut threaded onto the surface of the bolt, limiting blocks fixedly connected to both sides of the rotating block, and limiting grooves formed on one side of both the fixed block and the sliding block.

[0008] Preferably, the winding mechanism includes a spring fixedly connected to the inner cavity of the mounting housing, a connecting rod fixedly connected to the inner wall of the spring, a winding block fixedly connected to the surface of the connecting rod, and a connecting rope wound around the surface of the winding block.

[0009] Preferably, the surface of the mounting block is provided with a groove, and a slider is slidably connected to the inner wall of the groove.

[0010] Preferably, there are several limiting blocks and limiting slots, and the limiting blocks and limiting slots are arranged in a circular array with the center point of the rotating block as the center point.

[0011] Preferably, one end of the connecting rope on one side is fixedly connected to the chain surface above the fixed frame, and the other connecting rope is fixedly connected to the chain surface below the fixed frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the design of a rotating block and a limiting mechanism, allows for adjustment of the angle of the fixing frame. This enables the chain within its cavity to better adapt to various complex deformations of the rear beam of an automobile, effectively improving the accuracy and efficiency of rear beam alignment, reducing maintenance risks caused by inaccurate alignment, and thus ensuring maintenance quality and vehicle safety.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 As shown, a rear beam moving tool for automobile repair includes a beam straightening instrument body 1. Two pull towers 2 are slidably connected to the inner wall of the beam straightening instrument body 1. A chain 4 is provided on the surface of the pull tower 2. Through the cooperation of the beam straightening instrument body 1, the pull tower 2 and the chain 4, a pulling force can be applied to the deformed part of the automobile rear beam to perform a straightening operation.

[0017] The surface of the tower 2 is provided with a mounting block 3. A fixing block 5 is fixedly connected to one side of the mounting block 3, and a sliding block 6 is slidably connected to one side of the mounting block 3. A rotating block 7 is provided on one side of the fixing block 5. The rotating block 7 is located between the fixing block 5 and the sliding block 6. One end of the fixing block 5, the sliding block 6, and the rotating block 7 are all designed with a semi-circular structure. Through the cooperation of the above structures, it is convenient to install subsequent structures to make the rotating block 7 rotate, which provides the necessary prerequisites for the normal use of the device.

[0018] A fixed frame 15 is fixedly connected to one side of the rotating block 7, and part of the chain 4 is located in the inner cavity of the fixed frame 15, so as to facilitate the adjustment of the angle of the chain 4.

[0019] The inner cavity of the fixed block 5 is provided with a limiting mechanism 8, which enables the rotating block 7 to rotate, thereby allowing the fixed frame 15 to be angled and allowing the chain 4 to better adapt to the complex deformation of the rear beam of the car.

[0020] The limiting mechanism 8 includes a bolt 81 that is slidably connected to the inner wall of the fixed block 5. The surface of the bolt 81 is slidably connected to the inner wall of the rotating block 7 and the surface of the bolt 81 is slidably connected to the inner wall of the sliding block 6. By setting the bolt 81, the sliding block 6 and the rotating block 7 can move on the surface of the bolt 81 without falling off.

[0021] The bolt 81 is threaded with a nut 82, which is located on one side of the sliding block 6. By tightening the nut 82, the positions of the sliding block 6 and the rotating block 7 can be fixed to facilitate the normal use of the device.

[0022] Limiting blocks 83 are fixedly connected to both sides of the rotating block 7. Limiting grooves 84 are opened on one side of the fixed block 5 and the sliding block 6. There are several limiting blocks 83 and limiting grooves 84. The limiting blocks 83 and limiting grooves 84 are arranged in a circular array with the center point of the rotating block 7. The limiting blocks 83 and limiting grooves 84 work together. Under this action, after the rotating block 7 is rotated to a suitable angle, the limiting block 83 can be locked into the corresponding limiting groove 84, thereby fixing the angle of the rotating block 7, preventing accidental rotation during use, and ensuring the accuracy of the chain 4 angle adjustment.

[0023] The surface of the rotating block 7 is equipped with a pointer 9, and the surface of the fixed block 5 is equipped with a scale line 10. The pointer 9 and the scale line 10 are used together. By pointing the pointer 9 to different scales on the scale line 10, maintenance personnel can intuitively and accurately understand the rotation angle of the rotating block 7, so as to more accurately adjust the angle of the chain 4 to adapt to the complex deformation of the rear beam of the car.

[0024] The surface of the mounting block 3 is provided with two grooves 11. The grooves 11 are symmetrical with the center line of the mounting block 3. A slider 12 is slidably connected to the inner wall of the groove 11. One side of the slider 12 is fixedly connected to one end of the sliding block 6. Through the cooperation of the groove 11 and the slider 12, the sliding block 6 can be guided when it moves, so as to make the sliding block 6 more stable when in use and to prevent the sliding block 6 from rotating and falling off the surface of the bolt 81.

[0025] Both sides of the rotating block 7 are fixedly connected to the mounting shell 13. The inner cavity of the mounting shell 13 is provided with a winding mechanism 14. The winding mechanism 14 works in conjunction with the chain 4. Under this action, when the chain 4 breaks unexpectedly, the winding mechanism 14 can play a timely role in winding up the broken chain 4, preventing the chain 4 from flying everywhere and causing injury to maintenance personnel.

[0026] The winding mechanism 14 includes a spring 141 fixedly connected to the inner cavity of the mounting housing 13. A connecting rod 142 is fixedly connected to the inner wall of the spring 141. A winding block 143 is fixedly connected to the surface of the connecting rod 142. The winding block 143 has an I-shaped cross-section for easy installation of subsequent structures. A connecting rope 144 is wound around the surface of the winding block 143. One end of one connecting rope 144 is fixedly connected to the surface of the chain 4 above the fixed frame 15, and the other connecting rope 144 is fixedly connected to the surface of the chain 4 below the fixed frame 15.

[0027] Under this action, the two connecting ropes 144 can ensure that the chain 4 can be effectively wound up when it breaks at different positions. When the chain 4 is in normal use, the connecting ropes 144 will be pulled out as the chain 4 is stretched. The spring 141 will deform and store elastic potential energy. Once the chain 4 breaks accidentally, the spring 141 releases elastic potential energy, drives the connecting rod 142 to rotate, and then makes the winding block 143 rotate quickly, winding and retracting the connecting ropes 144, thereby winding the broken chain 4 to the vicinity of the mounting shell 13 and preventing it from flying everywhere.

[0028] It is worth noting that the technical features such as the main body 1 and the pull tower 2 of the beam straightening instrument proposed in this technical solution should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0029] Working principle: First, when the device is needed to repair the rear beam of a car, one end of the chain 4 can be connected to the rear beam. Then, depending on the deformation of the rear beam, the fixing effect on the sliding block 6 and the rotating block 7 can be released by rotating the nut 82. Then, the sliding block 6 and the rotating block 7 can be moved so that the limiting groove 84 is disengaged from the surface of the limiting block 83, making it easier to rotate the rotating block 7. This allows the angle of the fixing frame 15 to be adjusted, so that the chain 4 on the surface of the fixing frame 15 can better adapt to the complex deformation of the rear beam of the car. When the angle adjustment is completed and it needs to be fixed, the rotating block 7 and the sliding block 6 can be moved so that the limiting block 83 re-enters the inner cavity of the limiting groove 84, and the nut 82 can be tightened to fix the angle of the rotating block 7, making it convenient for the staff to use normally.

[0030] During the rotation of the rotating block 7, the pointer 9 can be driven to rotate. By cooperating with the scale line 10, the rotation angle of the rotating block 7 can be accurately known, thereby more accurately adjusting the angle of the fixing frame 15 and the chain 4, ensuring that the chain 4 can apply the corrective force to the rear beam of the car at the optimal angle.

[0031] After adjusting the angle of chain 4, start the main body 1 of the beam straightening instrument, and apply tension to chain 4 through components such as pull tower 2 to begin the straightening operation of the rear beam.

[0032] During this process, the winding mechanism 14 is always in standby mode. If the connection between the chain 4 and the rear beam of the car or the tower 2 breaks unexpectedly, the spring 141 will quickly contract, causing the connecting rod 142 and the winding block 143 to rotate. This will allow the connecting rope 144 to be wound up quickly, pulling the broken chain 4 in time to prevent it from flying everywhere and causing injury to maintenance personnel.
