[0002] In the current booming development of the electric bicycle manufacturing industry, the paint baking process, as a key link in improving the appearance quality and corrosion resistance of the bicycle frame, plays a crucial role in shaping product competitiveness.

[0003] With the continuous innovation of electric bicycle design styles and the differentiated expansion of functions across different models, the dimensions of the bicycle frame have become increasingly diverse, encompassing varying lengths, widths, heights, and complex structural forms. However, most existing positioning devices utilize fixed support components, whose positions are difficult to change once set, resulting in poor adaptability. Therefore, we propose a paint-coated positioning device for the electric bicycle frame. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for painting the frame of an electric bicycle, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric bicycle frame paint positioning device, including a support frame, on which U-shaped sliding plates are slidably installed on both the front and rear sides of the support frame, a mounting column is installed on the top surface of the U-shaped sliding plate, a plurality of support blocks are installed on the top of the mounting column, and an adjustment component for driving the movement of the U-shaped sliding plate is installed on the inner side of the support frame.

[0006] Two connectors are installed on one side of the top surface of the support frame. A swing plate is rotatably installed on one side of the connector. A limit block is fixedly installed between the two swing plates. A connecting column is installed between the two swing plates. Multiple insertion holes are opened on the outer side of the connecting column. A threaded assembly passing through the insertion holes is installed on one side of the support frame.

[0007] Preferably, the cross-section of the support block is V-shaped.

[0008] Preferably, the adjustment assembly includes multiple fixing rods, which are installed inside the support frame. A sliding plate is slidably installed on the outer side of the multiple fixing rods. A connecting rod is hinged to both sides of the sliding plate. One end of the connecting rod is hinged to one side of the U-shaped sliding plate. A first threaded rod is threaded inside the sliding plate. One end of the first threaded rod is rotatably installed inside the support frame, and the other end of the first threaded rod moves through the support frame.

[0009] Preferably, a rotating handle is fixedly installed at one end of the first threaded rod.

[0010] Preferably, the insertion holes are distributed in a ring at equal intervals on the outside of the connecting post.

[0011] Preferably, the threaded assembly includes a vertical plate, which is installed on one side of the support frame. A second threaded rod is threadedly connected inside the vertical plate. The second threaded rod passes through the insertion hole, and a knob is installed at one end of the second threaded rod. The major diameter of the second threaded rod matches the inner diameter of the insertion hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This electric bicycle frame painting positioning device involves placing the two bottom crossbeams of the electric bicycle frame into the support blocks on both sides. The support blocks support the crossbeams and cause the frame's uprights to abut against the limiting blocks, thus completing the positioning of the frame. By rotating the handle, the first threaded rod rotates, causing the sliding plate to slide outside the fixed rod. This, in turn, drives the U-shaped sliding plate to move through the connecting rod. The U-shaped sliding plate changes the position of the support blocks through the mounting column, thereby changing the distance between the front and rear support blocks. This allows for adjustment based on the distance between the crossbeams of the electric bicycle frame, enabling the device to adapt to frames of different sizes.

[0014] 2. The electric bicycle frame paint positioning device can rotate the knob to drive the second threaded rod to rotate and move. After the second threaded rod is disengaged from the insertion hole, the swing plate can be controlled to drive the limit block to rotate, changing the position of the limit block against the column. It can be adjusted according to the size of the frame, ensuring more accurate positioning. Attached Figure Description

[0019] 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.

[0020] Example 1

[0021] Please refer to Figure 1-3 As shown, this utility model provides a painting positioning device for the frame of an electric bicycle, including a support frame 1, with U-shaped slide plates 2 slidably installed on both the front and rear sides of the support frame 1, mounting posts 3 installed on the top surface of the U-shaped slide plates 2, multiple support blocks 4 installed on the top of the mounting posts 3, and an adjustment component for driving the movement of the U-shaped slide plates 2 installed on the inner side of the support frame 1.

[0022] Two connectors 10 are installed on one side of the top surface of the support frame 1. A swing plate 11 is rotatably installed on one side of the connector 10. A limit block 12 is fixedly installed between the two swing plates 11. A connecting post 13 is installed between the two swing plates 11. Multiple insertion holes 14 are opened on the outside of the connecting post 13. A threaded assembly passing through the insertion hole 14 is installed on one side of the support frame 1.

[0023] Specifically, the spacing between the front and rear support blocks 4 can be easily changed by adjusting the components, and the position of the limit block 12 can be easily changed by rotating the limit block 12, making it easy to adapt to electric vehicle body frames of different sizes.

[0024] Among them, the cross-section of the support block 4 is V-shaped, and the vehicle frame is supported by the support block 4.

[0025] The adjustment assembly includes multiple fixed rods 5, which are installed inside the support frame 1. A sliding plate 6 is slidably installed on the outside of the multiple fixed rods 5. Connecting rods 7 are hinged to both sides of the sliding plate 6. One end of the connecting rod 7 is hinged to one side of the U-shaped slide plate 2. A first threaded rod 8 is threaded inside the sliding plate 6. One end of the first threaded rod 8 is rotatably installed inside the support frame 1, and the other end of the first threaded rod 8 moves through the support frame 1. A rotating handle 9 is fixedly installed on one end of the first threaded rod 8. By rotating the rotating handle 9, the first threaded rod 8 is driven to rotate. The first threaded rod 8 can drive the sliding plate 6 to slide outside the fixed rods 5. The fixed rods 5 can drive the connecting rods 7 to move, thereby driving the U-shaped slide plate 2 to move.

[0026] Wherein: the insertion holes 14 are distributed in a ring at equal intervals on the outside of the connecting post 13. The threaded assembly includes a vertical plate 15, which is installed on one side of the support frame 1. The vertical plate 15 is threaded with a second threaded rod 16 inside the vertical plate 15. The second threaded rod 16 passes through the insertion hole 14. A knob 17 is installed at one end of the second threaded rod 16. The major diameter of the second threaded rod 16 matches the inner diameter of the insertion hole 14. Rotating the knob 17 drives the second threaded rod 16 to rotate, which can change the lateral position of the second threaded rod 16. When the second threaded rod 16 passes through the insertion hole 14, the position of the connecting post 13 is fixed. When the second threaded rod 16 is disengaged from the insertion hole 14, the connecting post 13, the swing plate 11 and the limiting block 12 can rotate.

[0027] Working principle: This utility model is a positioning device for painting electric bicycle frame. When in use, the two crossbeams at the bottom of the electric bicycle frame are placed in the support blocks 4 on both sides. The support blocks 4 support the crossbeams and make the uprights of the frame abut against the limiting block 12, thus completing the positioning of the frame. By rotating the handle 9, the first threaded rod 8 is rotated, which causes the sliding plate 6 to slide outside the fixed rod 5. Then, the U-shaped sliding plate 2 is moved through the connecting rod 7. The U-shaped sliding plate 2 changes the position of the support block 4 through the mounting column 3, thereby changing the distance between the front and rear support blocks 4. This makes it easy to adjust according to the distance of the crossbeams of the electric bicycle frame, so that the device can be adapted to different sizes of frames.

[0028] Rotating knob 17 can drive the second threaded rod 16 to rotate and move. After the second threaded rod 16 is disengaged from the insertion hole 14, the swing plate 11 can be controlled to drive the limit block 12 to rotate, changing the position of the limit block 12 against the column. This can be adjusted according to the size of the vehicle frame, ensuring more accurate positioning. After adjustment, the second threaded rod 16 is inserted into another insertion hole 14, fixing the angle position of the connecting column 13, thereby fixing the angle positions of the swing plate 11 and the limit block 12.

[0029] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
