Description

Technical Field

[0001] This utility model relates to the field of motor vehicle inspection technology, specifically a motor vehicle inspection lifting mechanism. Background Technology

[0002] When inspecting a motor vehicle, a lifting mechanism is needed to lift the vehicle so that staff can perform the inspection. A motor vehicle inspection lifting mechanism is a device used to lift a motor vehicle for various inspection and maintenance operations. It can lift the motor vehicle to a certain height so that staff can inspect, repair, or replace parts.

[0003] In the prior art, such as the lifting device for motor vehicle inspection proposed in patent application number "CN202322443745.2", a support shaft is fixedly installed between the arms of multiple sets of rotating shafts, a drive component for adjusting the included angle of the scissor arms is installed at the top of the base, and a limit wheel is fixedly installed at the end of the scissor arm away from the U-shaped block. This utility model has a quick alignment structure and improves lifting efficiency.

[0004] However, in the aforementioned patent application, when using the lifting mechanism, it is necessary to place the lifting mechanism on the ground below the vehicle. However, after the lifting mechanism in the aforementioned patent is placed on the ground, the bottom surface of the support frame contacts the ground. However, since the overall cross-section of the support frame is an inverted U-shape, the actual contact area between the support frame and the ground is small. This can easily lead to unstable support for other key lifting parts in the lifting mechanism, causing swaying and affecting the lifting operation. Utility Model Content

[0005] The purpose of this invention is to provide a motor vehicle inspection lifting mechanism to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A motor vehicle inspection lifting mechanism includes a base, a top plate movably mounted on the base, two adjustment mechanisms between the upper surface of the base and the bottom surface of the top plate, reinforcement mechanisms on the outer side wall of the base near the four corners, grooves on the front and rear outer side walls of the base, flip plates rotatably connected inside the two grooves, and fixing mechanisms on the outer side walls of the base near both sides.

[0008] The adjustment mechanism includes two sliders 1 and two sliders 2. Both sliders 1 are slidably connected to the upper surface of the base, and both sliders 2 are slidably connected to the bottom surface of the top plate. The fixing mechanism includes a knob and a limiting plate. The knob is fixedly connected to one end of the rotating shaft, and the limiting plate is slidably connected to the outer wall of the base.

[0009] Preferably, one of the sliders is rotatably connected to a movable rod via a shaft, and the end of the movable rod away from the slider is rotatably connected to one of the sliders via a shaft. The other slider is rotatably connected to a movable rod via a shaft, and the end of the movable rod away from the slider is rotatably connected to another slider via a shaft. The movable rod and the movable rod are rotatably connected via a shaft.

[0010] Preferably, two L-shaped mounting plates are fixedly connected to both outer side walls of the base and the top plate, and electric telescopic rods are installed on the inner walls of the four L-shaped mounting plates. One end of two of the electric telescopic rods is fixedly connected to two sliders, and one end of the other two electric telescopic rods is fixedly connected to two sliders.

[0011] Preferably, the outer wall of the base has vertical grooves near both sides, and a vertical rod is fixedly installed inside the vertical groove. The limiting plate is sleeved on the outside of the vertical rod. A spring sheet is sleeved on the outside of the vertical rod and between the upper surface of the limiting plate and the top of the inside of the vertical groove. One end of the spring sheet is fixedly connected to the top of the inside of the vertical groove, and the other end of the spring sheet is fixedly connected to the limiting plate.

[0012] Preferably, the outer wall of the knob has two limiting grooves, and the limiting grooves fit into the limiting insert plate.

[0013] Preferably, the reinforcement mechanism includes a limiting plate, which is fixedly connected to the outer wall of the base. A vertical plate is slidably connected inside the limiting plate, and the upper end of the vertical plate is fixedly connected to the top plate. A connecting block is slidably connected to the outer wall of the limiting plate, and one end of the connecting block is fixedly connected to the vertical plate.

[0014] Preferably, the connecting block is rotatably connected to the inside of the connecting block via a shaft, and several connecting blocks are fixedly connected to the outer wall of the limiting plate. The connecting blocks fit into the card plate. The outer wall of the connecting block is provided with a slot, and a stop block is inserted into the slot. A spring is installed between one end of the stop block and the inner wall of the slot.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model uses a rotating knob to drive the rotating shaft to rotate, causing the flipping plate to rotate out of the groove, so that the bottom surface of the flipping plate is in close contact with the ground. Under the action of the spring plate's rebound force, the limiting plate is driven to insert into the corresponding limiting groove, which can fix the position of the knob, thereby fixing the position of the rotating shaft and the flipping plate. Similarly, adjusting the other flipping plate to the same position with its bottom surface in close contact with the ground can increase the contact area between the bottom surface of the base and the ground, so that the base can be placed more stably on the ground, improving the overall placement stability of the lifting mechanism, avoiding shaking, and affecting the lifting operation. Moreover, the two flipping plates can be stored in the groove, reducing the volume of the lifting mechanism and making it easier for workers to carry and move the lifting mechanism.

[0017] 2. In this utility model, when the top plate moves up, each vertical plate and connecting block moves up with the vertical plate until the top plate moves up to the required height. Then, by clamping one end of the clamping plate onto the outside of the connecting block and fixing the position between the clamping plate and the connecting block by the spring and the stop block, the position between the vertical plate and the limiting plate can be fixed, further supporting and fixing the position of the top plate, improving the stability of the lifting mechanism, and better lifting the motor vehicle for inspection operations.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] A motor vehicle inspection lifting mechanism, such as Figures 1-6 As shown, the system includes a base 1, a top plate 2 movably mounted on top of the base 1, two adjustment mechanisms between the upper surface of the base 1 and the bottom surface of the top plate 2, reinforcement mechanisms on the outer walls of the base 1 near the four corners, grooves 22 on the front and rear outer walls of the base 1, and flip plates 3 rotatably connected inside the two grooves 22, and fixing mechanisms on the outer walls of the base 1 near both sides. The adjustment mechanisms include two sliders 6 and two sliders 8. The two sliders 6 are slidably connected to the upper surface of the base 1, and the two sliders 8 are slidably connected to the bottom surface of the top plate 2. The fixing mechanisms include a knob 10 and a limiting plate 11. The knob 10 is fixedly connected to one end of the rotating shaft 7, and the limiting plate 11 is slidably connected to the outer wall of the base 1.

[0029] The outer wall of the base 1 has vertical grooves near both sides. A vertical rod 12 is fixedly installed inside the vertical groove. A limiting plate 11 is sleeved on the outside of the vertical rod 12. A spring plate 13 is sleeved on the outside of the vertical rod 12, between the upper surface of the limiting plate 11 and the top of the vertical groove. One end of the spring plate 13 is fixedly connected to the top of the vertical groove, and the other end of the spring plate 13 is fixedly connected to the limiting plate 11. The outer wall of the knob 10 has two limiting grooves 21, which fit with the limiting plate 11. Under the action of the spring plate 13's rebound force, the limiting plate 11 is driven to insert into the corresponding limiting groove 21, fixing the position of the knob 10, thereby fixing the position of the rotating shaft 7 and the flipping plate 3. The bottom surface of both flipping plates 3 has several anti-slip grooves, which can increase the friction with the ground and make it more stable when placed on the ground.

[0030] Before using this lifting mechanism to inspect a motor vehicle, first move the limiting plate 11 upwards along the vertical rod 12, so that the bottom end of the limiting plate 11 moves out of the limiting groove 21, releasing the fixation of the knob 10. The spring plate 13 is compressed and contracted. Then, by rotating the knob 10, the rotating shaft 7 is rotated, thereby rotating the flip plate 3 out of the groove 22, so that the bottom surface of the flip plate 3 is close to the ground. At this time, release the limiting plate 11. Under the action of the spring plate 13's rebound force, the limiting plate 11 is driven to insert into the corresponding limiting groove 21. Then, the knob... The position of 10 is fixed, thereby fixing the position of the rotating shaft 7 and the flipping plate 3. Similarly, the other flipping plate 3 is adjusted to the same position where the bottom surface is close to the ground, which can increase the contact area between the bottom surface of the base 1 and the ground, so that the base 1 can be placed more stably on the ground for subsequent lifting of the motor vehicle to be inspected. After it is no longer needed, the two flipping plates 3 can be rotated back into the two grooves 22 and fixed, which can reduce the volume of the lifting mechanism and make it easier to carry and transfer the lifting mechanism.

[0031] One of the sliders 1-6 has a movable rod 1-4 rotatably connected inside via a shaft. The end of the movable rod 1-4 away from slider 1-6 is rotatably connected to one of the sliders 2-8 via a shaft. The other slider 1-6 has a movable rod 2-5 rotatably connected inside via a shaft. The end of the movable rod 2-5 away from slider 1-6 is rotatably connected to another slider 2-8 via a shaft. The movable rod 2-5 and the movable rod 1-4 are rotatably connected via a shaft. When the two sliders 2-8 and the two sliders 1-6 move closer to each other, they can drive the movable rod 1-4 and the movable rod 2-5 to rotate relative to each other, thereby causing the top plate 2 to move upward.

[0032] Two L-shaped mounting plates 23 are fixedly connected to the outer walls of the base 1 and the top plate 2. Electric telescopic rods 9 are installed on the inner walls of the four L-shaped mounting plates 23. One end of two of the electric telescopic rods 9 is fixedly connected to two sliders 6, and one end of the other two electric telescopic rods 9 is fixedly connected to two sliders 8.

[0033] During lifting, the lifting mechanism is placed under the vehicle chassis, with the base 1 and two tilting plates 3 placed close to the ground. At the same time, the four electric telescopic rods 9 on the four L-shaped mounting plates 23 are activated, causing each slider 1 6 and slider 2 8 to slide, so that the corresponding two sliders 1 6 and the corresponding two sliders 2 8 move closer to each other. This causes the movable rod 1 4 and movable rod 2 5 to rotate relative to each other, causing the top plate 2 to move away from the base 1, thus lifting the vehicle.

[0034] like Figures 5-6As shown, the reinforcement mechanism includes a limiting plate 14, which is fixedly connected to the outer wall of the base 1. A vertical plate 15 is slidably connected inside the limiting plate 14, and the upper end of the vertical plate 15 is fixedly connected to the top plate 2. A connecting block 20 is slidably connected to the outer wall of the limiting plate 14, and one end of the connecting block 20 is fixedly connected to the vertical plate 15. A connecting block 16 is rotatably connected inside the connecting block 20 via a shaft. Several connecting blocks 16 are fixedly connected to the outer wall of the limiting plate 14, and the connecting blocks 16 fit into the clamping plate 17. A slot 19 is opened on the outer wall of the connecting block 16, and a stop block 18 is inserted inside the slot 19. A spring is installed between one end of the stop block 18 and the inner wall of the slot 19. Under the action of the spring's rebound force, one end of the stop block 18 can be moved out of the slot 19 to block and limit one side of the clamping plate 17.

[0035] Specifically, when the top plate 2 moves upward, each vertical plate 15 moves upward along the inside of the limiting plate 14, and the connecting block 20 moves upward along with the vertical plate 15. After the top plate 2 moves to the required height, the clamping plate 17 is rotated, and one end of the clamping plate 17 is clamped onto the outside of the corresponding connecting block 16. During the clamping process, the inner wall of the clamping plate 17 passes the stop 18 and moves along the inclined surface of the stop 18, which can squeeze the stop 18, causing the stop 18 to move into the slot 19. The spring is compressed and contracted until the clamping plate 17 is completely clamped onto the outside of the connecting block 16. Under the action of the spring rebound force, one end of the stop 18 can be moved out of the slot 19, which can block and limit one side of the clamping plate 17, thereby fixing the position between the clamping plate 17 and the connecting block 16, and then fixing the position between the vertical plate 15 and the limiting plate 14. This further supports and fixes the position of the top plate 2, improves the stability of the lifting mechanism, and better lifts the vehicle for inspection operations.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
