[0002] When a car chassis has a problem, repair personnel need to enter to inspect and repair it. A flatbed truck is a tool that allows repair personnel to lie down and enter the chassis.

[0003] Current mobile reclining platforms, such as the one disclosed in Chinese Patent Publication No. CN217372323U for automobile repair, extend the entire platform using an extension plate. However, during use, if the vehicle chassis is too high, repair personnel cannot effectively use this type of platform to repair the chassis, making it very inconvenient. Therefore, this application proposes a mobile reclining platform for automobile repair. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a mobile reclining board for automobile repair.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] Preferably, one end of the torsion spring is fixedly connected to the fixed post, and the other end of the torsion spring is fixedly connected to the inner wall of the rotating ring.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up a lifting mechanism, pressing down the pull rod causes it to rotate, which in turn drives the rotating ring to rotate synchronously through the second rotating shaft. At this time, the ratchet on the rotating ring rotates forward, and the teeth of the ratchet push the locking block forward, thereby pushing the fixed collar to rotate. The fixed collar then drives the rotating shaft to rotate, and the rotating shaft drives the worm gear on it to rotate. Finally, the rotation of the worm gear synchronously drives the worm wheel to rotate, and the rotation of the worm wheel drives the reciprocating screw inside it to slide. The reciprocating screw then pushes the lying plate to slide up and down along the direction of the guide rod.

[0014] 2. By setting a locking block, the ratchet can be blocked and locked in a single direction of rotation, thereby achieving the purpose of driving the fixed collar and worm gear to rotate in one direction through the rotation of the ratchet. Attached Figure Description

The lifting mechanism includes a first rotating shaft 2 rotatably connected inside the fixed box 1, a worm gear 3 fixedly connected to the first rotating shaft 2, and a worm wheel 4 rotatably connected to the side of the fixed box 1 near the worm gear 3. It should be noted that by setting the worm gear 3 and worm wheel 4, the rotation of the worm gear 3 can drive the worm wheel 4 to rotate synchronously.

[0024] A fixing collar 5 is fixedly connected to one end of the first rotating shaft 2, and two locking blocks 6 are fixedly connected inside the fixing collar 5. It should be noted that by setting the locking blocks 6, the unidirectional rotation of the ratchet 11 can be blocked, thereby allowing the ratchet 11 to drive the worm gear 3 to rotate in one direction.

[0025] Inside the fixed box 1, a fixed plate 7 is fixedly connected to the side near the fixed collar 5. A fixed post 8 is fixedly connected to the side of the fixed plate 7 near the fixed collar 5. A rotating ring 9 is provided on the outer side of the fixed post 8 and is rotatably connected to the fixed plate 7. A torsion spring 10 is fixedly connected between the rotating ring 9 and the fixed post 8. It should be noted that by setting the torsion spring 10, the torsion force of the torsion spring 10 can drive the rotating ring 9 to automatically rotate and reset.

[0026] A ratchet 11 extending into the fixed collar 5 is fixedly connected to the end of the rotating ring 9 away from the fixed plate 7. It should be noted that by setting the ratchet 11, the ratchet 11 can be used to push the locking block 6 and the fixed collar 5 to rotate in one direction.

[0027] A second rotating shaft 12, which is fixedly connected to the rotating ring 9, is rotatably connected to the side of the fixed plate 7 away from the fixed column 8. The second rotating shaft 12 is rotatably connected to the fixed box 1. A push block 13 is fixedly connected to the end of the second rotating shaft 12 away from the fixed plate 7. A pull rod 14 is fixedly connected to the top of the push block 13. A reciprocating screw 15 is threadedly connected inside the worm gear 4. It should be noted that by setting the reciprocating screw 15, the rotation of the worm gear 4 can drive the reciprocating screw 15 to slide up and down along the inside of the fixed box 1, thereby pushing the lying plate 16 to move up and down.

[0028] A reciprocating lead screw 15 is fixedly connected to a lying plate 16 at its top, and four guide rods 17 are fixedly connected to the bottom of the lying plate 16. All four guide rods 17 are slidably connected to the fixed box 1. It should be noted that by setting the guide rods 17, the sliding direction of the lying plate 16 can be fixedly guided by the guide rods 17.
