Description

Technical Field

[0001] This utility model belongs to the field of sports helmet technology, and specifically relates to a clamping device for spraying sports helmets. Background Technology

[0002] In the production process of sports helmets, the spraying process is a crucial step, directly affecting the helmet's appearance quality, protective performance, and lifespan. With the booming development of the sports industry, the market demand for sports helmets has increased dramatically, and consumers' requirements for the personalization and refinement of helmet appearance are also rising. Traditional spraying methods often rely on manual handling of the helmet, which has many drawbacks.

[0003] Some existing simple clamping devices have poor versatility when fixing helmets, and cannot adapt to sports helmets of different sizes and shapes. In actual production, they need to be frequently replaced or adjusted, which increases production costs and time costs.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a clamping device for spraying sports helmets to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a clamping device for spraying sports helmets, comprising a mounting base, a driving mechanism mounted on the bottom of the mounting base, a moving mechanism threaded onto the driving mechanism, a plurality of inner support mechanisms rotatably mounted on the mounting base, the driving mechanism being rotatably mounted with the plurality of inner support mechanisms, a guide mechanism mounted on the top of the mounting base, the guide mechanism being slidably mounted with the moving mechanism, and a support block mounted on the top of the guide mechanism, the support block being semi-circular in shape.

[0008] Furthermore, the driving mechanism includes a drive motor, which is mounted on the mounting base, and a threaded rod is installed at the output end of the drive motor.

[0009] Furthermore, the moving mechanism includes a moving rod, which is threaded onto the threaded rod. A connecting block is mounted on the circumferential surface of the moving rod, and a rotating rod is rotatably mounted on one end of the connecting block.

[0010] Furthermore, the internal support mechanism includes a fixed block, which is mounted on the mounting base. A connecting rod is mounted on the fixed block, and the other end of the rotating rod is rotatably mounted in the middle of the connecting rod.

[0011] Furthermore, an inner support block is installed at the other end of the linkage to support the inner wall of the helmet using multiple inner support blocks.

[0012] Furthermore, the guiding mechanism includes multiple fixed rods, each of which is mounted on the mounting base. A bearing plate is mounted on the other end of each fixed rod, and the support block is mounted on top of the bearing plate.

[0013] Furthermore, a plurality of guide rods are installed at the bottom of the support plate, and the other ends of the plurality of guide rods are installed on the mounting base. The movable rod is slidably installed with the plurality of guide rods, and the movable rod is provided with a sliding groove for the plurality of guide rods to slide.

[0014] This utility model has the following beneficial effects:

[0015] In its initial state, the inner support mechanism is in a retracted state. When a sports helmet is placed on the support block, the semi-circular shape of the support block provides initial support for the helmet. Subsequently, the drive mechanism drives the moving mechanism to descend, and the inner support mechanism expands outward and makes close contact with the inside of the helmet, thus stably fixing the helmet from the inside. Due to the cooperation of multiple inner support mechanisms and the drive mechanism, this device can adapt to sports helmets of different sizes and shapes. By adjusting the operating parameters of the drive mechanism, various helmets can be effectively clamped without the need for frequent replacement or adjustment as with traditional simple clamping devices, greatly improving production efficiency.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements 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 the utility model.

[0028] Please see Figures 1-6 As shown, this utility model is a clamping device for spraying sports helmets, including a mounting base 1. A driving mechanism 2 is mounted on the bottom of the mounting base 1. A moving mechanism 3 is threaded onto the driving mechanism 2. Multiple inner support mechanisms 4 are rotatably mounted on the mounting base 1. The driving mechanism 2 is rotatably mounted with the multiple inner support mechanisms 4. A guide mechanism 5 is mounted on the top of the mounting base 1. The guide mechanism 5 is slidably mounted with the moving mechanism 3. A support block 6 is mounted on the top of the guide mechanism 5. The support block 6 is semi-circular in shape.

[0029] Mounting base 1 is usually installed in the spraying area of ​​the spraying equipment. First, the drive mechanism 2 is started. Since the moving mechanism 3 is threadedly installed on the drive mechanism 2, the rotational motion of the drive mechanism 2 will be converted into the linear lifting motion of the moving mechanism 3. During the lifting and lowering process of the moving mechanism 3, it is slidably installed with the guide mechanism 5. The guide mechanism 5 provides a stable guide for the moving mechanism 3, ensuring the accuracy and smoothness of its linear movement. As the moving mechanism 3 rises and falls, multiple inner support mechanisms 4, which are rotatably installed with the drive mechanism 2, will be linked. When the moving mechanism 3 rises, the inner support mechanisms 4 retract inward; when the moving mechanism 3 falls, the inner support mechanisms 4 expand outward. In the initial state, the inner support mechanisms 4 are in a retracted state, and the sports helmet is placed on the support block 6. The semi-circular design of the support block 6 can initially support the helmet. Subsequently, the drive mechanism 2 drives the moving mechanism 3 to fall, and the inner support mechanisms 4 expand outward and make close contact with the inside of the helmet, thereby stably fixing the helmet from the inside. Due to the cooperation of multiple inner support mechanisms 4 and drive mechanism 2, this device can adapt to sports helmets of different sizes and shapes. By adjusting the operating parameters of drive mechanism 2, various helmets can be effectively clamped without the need for frequent replacement or adjustment as with traditional simple clamping devices, greatly improving production efficiency.

[0030] In one embodiment, the drive mechanism 2 includes a drive motor 201, which is mounted on the mounting base 1, and a threaded rod 202 is mounted on the output end of the drive motor 201.

[0031] The moving mechanism 3 includes a moving rod 301, which is threadedly mounted on the threaded rod 202. A connecting block 302 is mounted on the circumferential surface of the moving rod 301, and a rotating rod 303 is rotatably mounted on one end of the connecting block 302.

[0032] The inner support mechanism 4 includes a fixing block 401, which is mounted on the mounting base 1. A connecting rod 402 is mounted on the fixing block 401, and the other end of the rotating rod 303 is rotatably mounted in the middle of the connecting rod 402.

[0033] The other end of the linkage 402 is equipped with an inner support block 403, so that the inner wall of the helmet can be supported by multiple inner support blocks 403.

[0034] The guide mechanism 5 includes multiple fixing rods 501, each of which is mounted on the mounting base 1. A bearing plate 502 is mounted on the other end of each fixing rod 501, and the support block 6 is mounted on the top of the bearing plate 502.

[0035] The bottom of the support plate 502 is equipped with a plurality of guide rods 503, the other end of the plurality of guide rods 503 is mounted on the mounting base 1, the movable rod 301 is slidably mounted with the plurality of guide rods 503, and the movable rod 301 is provided with a sliding groove for the plurality of guide rods 503 to slide.

[0036] When the drive motor 201 starts, its output end drives the threaded rod 202 to rotate. Since the moving rod 301 is threaded onto the threaded rod 202, the rotation of the threaded rod 202 causes the moving rod 301 to move linearly along the axial direction of the threaded rod 202. During the linear movement of the moving rod 301, the connecting block 302 mounted on its circumferential surface also moves synchronously. The rotating rod 303, which is rotatably mounted on one end of the connecting block 302, will rotate around the connection point between the connecting block 302 and the moving rod 301. The other end of the rotating rod 303 is rotatably mounted in the middle of the connecting rod 402. When the rotating rod 303 rotates, it applies a force to the connecting rod 402, causing the connecting rod 402 to rotate around its connection point with the fixed block 401. The other end of the connecting rod 402 is equipped with an inner support block 403. As the linkage rod 402 rotates, multiple inner support blocks 403 will simultaneously shift. When the moving rod 301 moves downward, the rotating rod 303 pushes the linkage rod 402 to rotate outward, thereby gradually opening the inner support blocks 403 outward until they are in close contact with the inner wall of the helmet placed on the support block 6 and provide stable support force, thus achieving reliable clamping of the helmet. When the moving rod 301 moves upward, the rotating rod 303 pulls the linkage rod 402 to rotate inward, and the inner support blocks 403 retract inward, facilitating the placement and removal of the helmet. By using the rotational motion of the drive motor 201 to convert the opening and retraction of the inner support blocks 403, it effectively adapts to sports helmets of different sizes and shapes, ensuring that the helmet can be firmly fixed in the appropriate position during the spraying process, ensuring the smooth progress of the spraying process and the stability of the spraying quality.

[0037] During the linear movement of the moving rod 301, it slides and engages with the guide rod 503 through the sliding groove. The guide rod 503 provides precise guidance, ensuring that the moving rod 301 can only move stably up and down along the direction of the guide rod 503, preventing it from deviating or rotating during the movement, and ensuring the accuracy and smoothness of the entire transmission process. Multiple fixed rods 501 securely mount the bearing plate 502 above the mounting base 1, providing a stable support foundation for the support block 6. The support block 6 is used to place the sports helmet and, together with the inner support block 403, secures the helmet from the inside in all directions, ensuring that the helmet can be firmly clamped in the set position during the spraying operation.
