Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive door panel processing technology, and in particular to a fixed bracket for automotive door panel processing. Background Technology
[0002] Sheet metal is characterized by its light weight, high strength, electrical conductivity, low cost, and good mass production performance, and is widely used in various industries. Products processed through sheet metal manufacturing are called sheet metal parts. The term "sheet metal part" generally varies across different industries and is often used in assembly. Car doors are typically made of sheet metal, and these doors require further processing before they can be used. In current technology, when processing car door panels, they need to be fixed with brackets to facilitate processing. Existing brackets are usually simply welded steel pipes to fix the car door panel to the bracket, and they can generally only be removed after processing is complete. Therefore, the bracket needs to be moved around during different processing steps. However, the existing bracket design is relatively simple and inconvenient to move. When processing on uneven ground, the bracket cannot maintain stability and is prone to tipping over, thus affecting the processing of the car door panel. Utility Model Content
[0003] The purpose of this utility model is to provide a fixed bracket for processing automobile door panels, which can be easily moved and can remain stable on uneven ground to prevent the bracket from tipping over and ensure the stable processing of automobile door panels.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] A fixed bracket for processing automotive door panels includes a base, an adjustment device at the upper end of the base, a U-shaped rod vertically arranged at the upper end of the adjustment device, a support device between the left and right ends of the U-shaped rod, a first gear on the left and right sides of the front and rear ends of the base, a support frame rotatably connected to the corresponding first gear on the left and right sides of the front and rear ends of the base, a second gear meshing with the corresponding first gear rotatably connected inside each support frame near the corresponding first gear, a third gear meshing with the corresponding second gear rotatably connected inside each support frame near the corresponding second gear, and a caster wheel on the outer side of each third gear.
[0006] Each second gear has several equally spaced limiting holes at one end. Each support frame has a limiting cylinder at one end near the corresponding limiting hole. Each limiting cylinder has a pull rod slidably connected to the corresponding limiting hole inside. Each pull rod has a limiting block slidably connected to the limiting cylinder on its outer side. A spring is provided between the corresponding limiting block and the corresponding limiting cylinder on the outer side of each pull rod. The radii of the first gear, the second gear, and the third gear are all the same.
[0007] The outer side of the U-shaped rod is detachably provided with a first fixing device, one end of the U-shaped rod is provided with a first limiting slide opening, the inside of the U-shaped rod is slidably connected with a threaded sleeve that is slidably connected with the first limiting slide opening, and the end of the threaded sleeve near the first limiting slide opening is detachably provided with a second fixing device.
[0008] By adopting the above technical solution, when processing and fixing a car door panel, the car door panel is aligned with the U-shaped rod. Then, the support device is moved and adjusted according to the size of the car door panel. The first fixing device is installed on the U-shaped rod, and the car door panel is initially fixed by the first fixing device. The second fixing device is installed on the threaded sleeve. Then, pulling the second fixing device causes the threaded sleeve to slide relative to the first limiting slide in the U-shaped rod. The position of the second fixing device is adjusted, and the car door panel is stably fixed by the second fixing device. By adjusting the adjusting device on the base, the height of the U-shaped rod can be adjusted, thereby adjusting the height of the car door panel. When moving the car door panel, the U-shaped rod is pushed. Then, the casters are rotated for easy movement. When the ground is uneven, the pull rod slides relative to the limit sleeve, thereby causing the positioning block to slide relative to the limit sleeve, compressing the spring. The pull rod slides out of the limit opening, and then the support frame rotates relative to the first gear and the base, thereby causing the second gear to rotate. The rotation of the second gear causes the third gear to rotate, keeping the casters relatively perpendicular to the ground. The angle of the support frame relative to the base is adjusted to keep the base level. After adjustment, the limit rod slides relative to the limit opening under the action of the spring, which can lock the second gear and prevent it from rotating, ensuring that the base remains level on uneven ground.
[0009] A further feature of this invention is that the adjusting device includes worm gears rotatably connected to both the left and right sides of the upper end of the base, a worm rod rotatably connected to the upper end of the base near the worm gears and arranged horizontally and meshing with each worm gear, and a first threaded rod arranged vertically at the upper end of each worm gear. The lower end of the U-shaped rod has first threaded openings at both the left and right ends that are threaded to the corresponding first threaded rods, and a handle is provided at one end of the worm rod.
[0010] A further feature of this invention is that the first fixing device includes a detachable buckle slidably connected to the upper end of the U-shaped rod and a fixing rod disposed at one end of the buckle.
[0011] A further feature of this invention is that the second fixing device includes an L-shaped plate slidably connected to the upper end of the U-shaped rod, a first bolt rotatably and slidably connected to the threaded sleeve at one end of the L-shaped plate near the first limiting slide opening, a second limiting slide opening at the upper end of the L-shaped plate, a second bolt slidably connected inside the second limiting slide opening, a Z-shaped plate rotatably connected to the outside of the second bolt, and a nut threadedly connected to the outside of the bolt.
[0012] A further feature of this invention is that the support device includes a limiting rod disposed between the left and right ends of the U-shaped rod, a sliding sleeve disposed at both ends of the limiting rod and slidably connected to the U-shaped rod, a second threaded opening on one side of each sliding sleeve, a second threaded rod threadedly connected to the inside of each second threaded opening, and a knob disposed at one end of each threaded rod away from the U-shaped rod.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This system allows for easy movement of car door panels and maintains stability on uneven surfaces, preventing the door panels from tipping over and causing damage that could affect processing. Pulling the lever extends it from the limiting slot, compressing the spring in the limiting block. This causes the support frame to rotate relative to the base. The first gear drives the second gear, which in turn drives the first gear, ensuring the caster wheels remain perpendicular to the ground. Adjusting the angle of the support frame relative to the base leveles the base. Once adjusted, the spring force causes the lever to engage the second gear in the limiting slot, preventing rotation and ensuring the base remains level. Attached Figure Description

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

Each second threaded rod 11 has a knob 12 at its end away from the limiting rod 8, which can adjust the height of the limiting rod 8 in the U-shaped rod 6 according to the size of the car door panel, thereby facilitating the fixing of the car door panel. A first fixing device is detachably provided on the outside of the U-shaped rod 6, including multiple detachably provided buckles 13 slidably connected to the outside of the U-shaped rod 6. Each buckle has a fixing rod 14 at its front end. Inserting the fixing rod 14 into the hole on the car door panel can initially fix the car door panel.
[0026] The front end of the U-shaped rod 6 is provided with a first limiting slide 15. The interior of the U-shaped rod 6 is slidably connected with multiple threaded sleeves 16 that are slidably connected with the first limiting slide 15. The front end of each threaded sleeve 16 is provided with a second fixing device, including a first bolt 17 that is threadedly connected to the interior of the threaded sleeve 16. An L-shaped plate 18 is rotatably and slidably connected to the outside of the first bolt 17. A second limiting slide 19 is provided at the upper end of the L-shaped plate 18. A second bolt 20 is slidably connected inside the second limiting slide 19. A Z-shaped plate 22 is provided below the L-shaped plate 18 on the outside of the second bolt 20. A nut 21 is threadedly connected above the L-shaped plate 18 on the outside of the second bolt 20, which can facilitate the adjustment of the position of the Z-shaped plate 22, thereby facilitating the secure fixing of the car door panel.
[0027] A first gear 23 is provided on both the left and right sides of the front and rear ends of the base 1. A support frame 24, rotatably connected to the first gear 23, is rotatably connected to each of the left and right sides of the front and rear ends of the base 1. A second gear 25, meshing with the corresponding first gear 23, is rotatably connected inside each support frame 24. A third gear 26, meshing with the corresponding second gear 25, is rotatably connected inside each support frame 24. A caster wheel 32 is provided on the outer side of each third gear 26, allowing adjustment of the support frame's rotation according to the unevenness of the ground, ensuring stable processing of the car door panel. The diameters of the first gear 23, second gear 25, and third gear 26 are all the same, ensuring... After the support frame rotates, the casters 32 remain relatively perpendicular to the ground, thus facilitating movement. Each second gear 25 has several equally spaced limiting holes 27 at one end near the corresponding knob 12. Each support frame 24 has a limiting cylinder 28 near the corresponding limiting hole 27 at one end near the corresponding knob 12. Each limiting cylinder 28 has a pull rod 29 slidably connected inside, which is slidably connected to the corresponding limiting hole 27. A limiting block 30 is provided on the outside of the pull rod 29, which is slidably connected to the corresponding limiting cylinder 28. A spring 31 is provided on the outside of the pull rod 29 between the corresponding limiting block 30 and the corresponding limiting cylinder 28, which can drive the pull rod 29 to return to its original position.
[0028] Usage: When processing and fixing a car door panel, align the car door panel with the U-shaped rod 6. Then, adjust the support device according to the size of the car door panel. Install the first fixing device on the U-shaped rod 6 to initially fix the car door panel. Install the second fixing device on the threaded sleeve 16, and then pull the second fixing device to make the threaded sleeve 16 slide relative to the limiting port 27 in the U-shaped rod 6. Adjust the position of the second fixing device to stably fix the car door panel. The height of the U-shaped rod 6 can be adjusted by adjusting the adjustment device on the base 1, thereby adjusting the height of the car door panel. When moving the car door panel, push the U-shaped rod 6 to drive the universal wheel 32 to rotate for easy movement. When the ground is uneven, the pull rod 29 slides relative to the limiting sleeve, thereby causing the point block to slide relative to the limiting sleeve, compressing the spring 31. The pull rod 29 slides out of the limiting port 27, and then pulls the support frame to rotate relative to the first gear 23 and the base 1, thereby causing the second gear 25 to rotate. The rotation of the second gear 25 causes the third gear 26 to rotate, keeping the caster wheel 32 relatively perpendicular to the ground. The angle of the support frame relative to the base 1 is adjusted to keep the base 1 horizontal. After adjustment, the limiting rod 8 slides relative to the limiting port 27 under the action of the spring 31, which can lock the second gear 25 and prevent it from rotating, ensuring that the base 1 remains horizontal on uneven ground.
[0029] By cranking the handle 4, the worm gear 3 is driven to rotate, which in turn drives the worm wheel 2 to rotate. The worm wheel 2 then drives the first threaded rod 5 to rotate, thereby causing the first threaded rod 5 to rotate relative to the first threaded opening 7. Since both first threaded rods 5 rotate simultaneously relative to their corresponding first threaded openings 7, the U-shaped rod 6 can move up and down relative to the second threaded rod 11, thereby adjusting the height of the car door panel.
[0030] By rotating the knob 12, the knob 12 drives the second threaded rod 11 to rotate relative to the second threaded opening 10, thereby releasing the U-shaped rod 6. Pulling the limiting rod 8 can drive the limiting sleeve to slide relative to the U-shaped rod 6, thereby adjusting the position of the support device. After adjustment, turn the knob 12 to fix the position of the sliding sleeve 9.
[0031] Push the buckle 13 to slide it relative to the U-shaped rod 6, thereby fixing the buckle 13 to the U-shaped rod 6. Moving the buckle 13 relative to the U-shaped rod 6 can adjust the position of the buckle 13. Insert the fixing rod 14 into the hole in the car door panel to fix the car door panel.
[0032] Screw the first bolt 17 into the threaded sleeve 16, and fix the Z-shaped plate 22 to the L-shaped plate 18 with the second bolt 20 and nut 21. Pull the L-shaped plate 18, and the first bolt 17 can be used to adjust the L-shaped plate 18 to a suitable position. Then tighten the first bolt 17, and the L-shaped plate 18 and the threaded sleeve 16 can clamp the first limiting slide 15, thereby fixing the L-shaped plate 18. Pull the second bolt 20, and the second bolt 20 can be rotated or slid in the second limiting slide 19, thereby adjusting the position of the Z-shaped plate 22, which is convenient for fixing the car door panel.
[0033] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
