DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1: Reference Figure 1-Figure 9 , a car spray paint flip stand with an automatic locking mechanism, which is used in the field of flip stands, includes: two support frames 1, between which a first rotating shaft 2 is rotatably arranged. On one side of the first rotating shaft 2, three positioning rods 8 are fixedly arranged, and these positioning rods 8 are used to support the door body. In particular, a reducer 3 and a motor 4 (power source) are fixedly arranged on one side of one of the support frames 1. The output end of the reducer 3 is fixedly connected to the first rotating shaft 2, and the output end of the motor 4 is fixedly connected to the input end of the reducer 3. Such an arrangement enables that when the motor 4 is started, it can drive the reducer 3 and then drive the first rotating shaft 2 to rotate, thereby realizing the flipping of the door body, and the reducer 3 adopts a worm gear reducer, which has a self-locking function when it is stopped.

[0020] A support rod 22 is fixedly arranged on the top of the positioning rod 8, and a support seat 23 is fixedly arranged on the top of the support rod 22. These support seats 23 are in contact with the flange of the door body to provide additional support and positioning.

[0021] In addition, two fixing seats 5 are respectively fixedly arranged on the top of the support frame 1. A rectangular groove 34 is provided on the side of the two fixing seats 5 close to each other, and a sliding block 35 is slidably arranged in the rectangular groove 34. A support bar 6 for supporting the door body is arranged between the two sliding blocks 35.

[0022] In order to fix the door body, clamping mechanisms are also provided. These clamping mechanisms are arranged in the positioning rod 8 and cooperate with the flange in the door body to fix the door panel on the positioning rod 8.

[0023] In order to provide a convenient operation method, a pedal 7 is also included, which is rotatably arranged on one side of one of the support frames 1. The pedal 7 is connected to the support bar 6 and the clamping mechanism through a transmission member. When the staff steps on the pedal 7, the stepping force will drive the transmission member to work, thereby causing the support bar 6 to move upward to support the door panel, and at the same time release the clamping mechanism from fixing the door panel. In order to save more effort, a hydraulic cylinder 42 can be detachably and rotatably installed between the support frame 1 and the pedal 7 (specifically, a pin shaft, a bearing, and a retaining spring can be used for detachable rotation). The hydraulic cylinder 42 is used to drive the pedal 7 to rotate, and there is no need to step on it (such as Fig.10 as shown).

[0024] In order to ensure that the door body does not fall off during the flipping process, a locking mechanism is also provided on the first rotating shaft 2 .

[0025] Furthermore, a third rotating shaft 10 is rotatably arranged between the two support frames 1, and the pedal 7 is fixedly arranged at one end of the third rotating shaft 10. At the same time, a second rotating shaft 9 is rotatably arranged between the two support frames 1. The outer walls of the third rotating shaft 10 and the second rotating shaft 9 are both fixedly sleeved with meshing first gears 30. The sliding block 35 is connected to the second rotating shaft 9 through a connecting member.

[0026] The specific structure of the connecting member includes a rotating seat 36 fixedly arranged on one side of the sliding block 35, and a second sliding rod 32 is rotatably arranged on one side of the rotating seat 36. A second sleeve rod 31 is slidably sleeved on the outer wall of the second sliding rod 32, and the other end of the second sleeve rod 31 is fixedly arranged on the outer wall of the second rotating shaft 9, so that when the pedal 7 is flipped downward, the second sleeve rod 31 and the second sliding rod 32 can be driven to flip upward, thereby driving the support bar 6 to move upward.

[0027] A guide rod 38 is fixedly arranged in the rectangular groove 34, and a tension spring 39 is sleeved on the outer wall of the guide rod 38. The sliding block 35 is slidably sleeved on the guide rod 38, and the two ends of the tension spring 39 are respectively fixedly connected to the bottom wall of the rectangular groove 34 and the bottom of the sliding block 35. Such an arrangement enables the tension spring 39 to drive the sliding block 35 to return downward when the pedal 7 is not subjected to force, and drive the pedal 7 to flip upward, so as to facilitate the subsequent operation.

[0028] The specific structure of the clamping mechanism includes a second sliding ring 24 slidably sleeved on the outer wall of the positioning rod 8. The outer wall of the positioning rod 8 is provided with a first rectangular opening 25, and a first rectangular block 26 is slidably arranged in the first rectangular opening 25. The first rectangular block 26 is fixedly arranged in the second sliding ring 24, and a limit rod 27 used in conjunction with the door body flange is fixedly arranged on the top of the second sliding ring 24. A pull rope 14 is arranged in the positioning rod 8, one end of the pull rope 14 is fixedly connected to the first rectangular block 26, and the other end is fixedly wound around the outer wall of the second rotating shaft 9. During the resetting and rotation of the second rotating shaft 9, the pull rope 14 can be stored so that the pull rope 14 can be rewound around the second rotating shaft 9. Preferably, a take-up drum can be installed on the second rotating shaft 9, and the diameter of the take-up drum is larger than the second rotating shaft 9, and the take-up drum will not touch the third rotating shaft 10. The pull rope 14 can be fixedly wound around the outer wall of the take-up drum, thereby driving the limit rod 27 to resist the door body flange. In order to adapt to the door body flange at different distances, the pull rope 14 is fixedly connected to the second rotating shaft 9 through another detachable connecting rope. The length of this connecting rope is cut according to the door body flange distance, so that it only needs to be adjusted once in the case of batch processing.

[0029] The specific structure of the locking mechanism includes a first sleeve rod 12 fixedly arranged on one side of the first rotating shaft 2. A first sliding ring 17 corresponding to the adjusting ring 18 is slidably sleeved on the outer wall of the first sleeve rod 12, and a limit ring 13 corresponding to the fixed block 11 is also slidably sleeved. The pull rope 14 is located between the corresponding first sliding ring 17 and the limit ring 13, and the limit ring 13 is fixedly connected to the corresponding adjusting ring 18. An electric push rod 16 is fixedly arranged on the outer wall of the first rotating shaft 2. Such an arrangement enables the electric push rod 16 to push the first sliding ring 17 closer to the limit ring 13 when it is started, so as to clamp and fix the pull rope 14.

[0030] Example 2: Reference Figure 1-Figure 10 , based on the improvement of Example 1: a connecting rod 37 is fixedly arranged between the two sliding blocks 35, and the support bar 6 is rotatably sleeved on the connecting rod 37. Two second gears 40 are rotatably sleeved on the outer wall of the connecting rod 37, and the two second gears 40 are respectively fixedly arranged at the two ends of the support bar 6. A rack 41 meshing with the second gear 40 is fixedly arranged on one side of the fixing seat 5. Such a setting enables the connecting rod 37 and the second gear 40 to move when the sliding block 35 moves, and then the support bar 6 is turned over by the rack 41, which effectively reduces the paint adhering to the bottom surface of the support bar 6, thereby reducing the paint on the surface of the support bar 6 adhering to the door body when the support bar 6 contacts the door body.

[0031] In order to adjust the position of the positioning rod 8, an adjustment ring 18 corresponding to the positioning rod 8 is slidably sleeved on the outer wall of the first rotating shaft 2. A slide groove 19 is provided on the outer wall of the first rotating shaft 2, and a slider 20 corresponding to the adjustment ring 18 is slidably set in the slide groove 19. The slider 20 is fixed in the adjustment ring 18, and a fixing block 11 is fixed on the top of the adjustment ring 18. The positioning rod 8 penetrates and is fixedly set on one side of the fixing block 11. In order to limit the adjustment ring 18, the same bolt 21 is threadedly set on one side of the adjustment ring 18 and the slider 20, and one end of the bolt 21 is in conflict with the slide groove 19. When the position of the hole on one side of the door body changes, it can be adjusted according to the position of the hole.

[0032] In order to ensure that the electric push rod 16 can stably push the three first sliding rings 17 at the same time, the first sliding rod 15 is slidably arranged in the first set of rods 12. The outer wall of the first set of rods 12 is provided with a second rectangular opening 28, and a second rectangular block 29 is slidably arranged in the second rectangular opening 28. The second rectangular block 29 is fixedly arranged between the corresponding first sliding ring 17 and the first sliding rod 15, and the output end of the electric push rod 16 is fixedly connected to the first sliding rod 15.

[0033] First, step on the pedal 7, and the pedal 7 can drive the third rotating shaft 10 to rotate during the downward swinging process. During the rotation of the third rotating shaft 10, the second rotating shaft 9 can be driven to rotate in the opposite direction through the two meshing first gears 30. At this time, the pull rope 14 will be unwound, and the limit rod 27 will be moved to the side away from the support seat 23. During the reverse rotation of the second rotating shaft 9, the second set of rods 31 can be driven to swing upward. The upward swinging of the second set of rods 31 can drive the sliding block 35 to move upward through the second sliding rod 32 and the rotating seat 36. At the same time, the second sliding rod 32 slides in the second set of rods 31 and rotates on the rotating seat 36, and the sliding block 35 can drive the support bar 6 to move upward through the connecting rod 37 during the upward movement of the sliding block 35, and the support bar 6 can be driven to rotate through the meshing second gear 40 and the rack 41 during the upward movement of the supporting bar 6, and the sliding block 35 can stretch the guide rod 38 during the upward movement until the supporting bar 6 rotates 180°, and the bottom end of the door panel is placed on the supporting bar 6, and the door panel is pushed inward until the positioning rod 8 contacts the door panel and the supporting seat 23 contacts the flange; Then release the foot, at this time the sliding block 35 can be reset and moved downward under the action of the tension spring 39, the sliding block 35 can move downward to drive the second rotating shaft 9 to rotate through the rotating seat 36, the second sliding rod 32 and the second set rod 31, and the second rotating shaft 9 can drive the third rotating shaft 10 to rotate in the opposite direction through the meshing first gear 30 during the rotation, and drive the pedal 7 to swing upward, and the second rotating shaft 9 can store one end of the pull rope 14 during the rotation, and drive the other end of the pull rope 14 to move in the positioning rod 8, and can drive the first rectangular block 26 to move, and the first rectangular block 26 can drive the second sliding ring 24 to move during the movement, and the movement of the second sliding ring 24 can drive the limit rod 27 to contact the flange in the door body, and the door body is fixed on the three positioning rods 8 by the pulling force; Secondly, the electric push rod 16 is started to extend, and the extension of the electric push rod 16 can drive the first sliding rod 15 to move in the first set rod 12, and drive the first sliding ring 17 to move through the second rectangular block 29, and can drive the first sliding ring 17 to move toward the limit ring 13, and the pull rope 14 is fixed by clamping the first sliding ring 17 and the limit ring 13; Finally, the motor 4 is started to drive the reducer 3 to rotate, and the first rotating shaft 2 is driven to rotate, thereby driving the door body to flip (the door body flip angle is less than 50 degrees), flipping the lower end of the door body to expose it for easy painting, and the door body does not need to be flipped 360 degrees; When the position of the positioning rod 8 needs to be adjusted, the bolt 21 is rotated in the opposite direction to make one end of the bolt 21 move away from the first rotating shaft 2, and then the adjusting ring 18 is pushed to move, which can drive the slider 20 to move in the slide groove 19 and drive the fixed block 11 to move, thereby driving the positioning rod 8 to move and adjust the position of the positioning rod 8.

[0034] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 4 and the electric push rod 16 are commonplace, and are conventional means or common knowledge, and will not be elaborated here.
