DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1
[0024] See also Figure 1-5A rotating fixture for helmet decals, comprising a press clamping mechanism, a positioning mechanism and a rotating assembly, wherein the press clamping mechanism comprises a support rod 1, a connecting rod 2, a sliding plate 3, a first spring 4 and a clamping sleeve 5, wherein the support rod 1 is installed inside the clamping sleeve 5 and is connected to the clamping sleeve 5, wherein both ends of the connecting rod 2 are rotatably connected to the support rod 1 and the sliding plate 3, wherein the first spring 4 is installed inside the clamping sleeve 5 and the two ends are fixedly connected to the clamping sleeve 5 and the support rod 1, wherein the positioning mechanism comprises a clamping block 6, a second spring 7, a sliding frame 8 and a fixing sleeve 9, wherein the clamping block 6 and the second spring 7 are installed inside the support rod 1, and the clamping block 6 is slidably connected to the support rod 1, wherein both ends of the second spring 7 are fixedly connected to the support rod 1 and the clamping block 6, wherein the sliding frame 8 is slidably connected to the fixing sleeve 9.
[0025] In this embodiment, the press-and-clamp mechanism includes a support rod 1, a connecting rod 2, a sliding plate 3, a first spring 4 and a clamping sleeve 5. When in use, the helmet is directly placed on the first contact block 18. At this time, the helmet is pressed, and the support rod 1 slides inside the clamping sleeve 5 under the action of pressure, and the first spring 4 fixedly connected to the receiving plate 20 is compressed inside the clamping sleeve 5, and the receiving plate 20 slides in the first slide groove 15, so that the connecting rod 2 applies pressure to the sliding plate 3, so that the sliding plate 3 slides in the second slide groove 16 on the clamping sleeve 5, so that the second contact block 19 on the sliding plate 3 contacts the inside of the helmet, and the positioning plate 21 also starts to slide inside the third slide groove 17 under the movement of the support rod 1, so that the blocking block 6 enters the inside of the fixed sleeve 9.
[0026] In this embodiment, the positioning mechanism includes a card block 6, a second spring 7, a sliding frame 8 and a fixed sleeve 9. When in use, the card block 6 is compressed after contacting the fixed sleeve 9, so that the card block 6 is compressed into the positioning plate 21, and at the same time, the second spring 7 is also compressed. When the card block 6 contacts the extrusion block 25 on the sliding frame 8, the compressed second spring 7 begins to release elastic potential energy, pushing the card block 6 out of the positioning plate 21, and the limit block 22 on the card block 6 slides in the limit slide groove 23 in the positioning plate 21. After the extrusion block 25 is squeezed by the clamping block 6, the force is transmitted to the sliding frame 8, so that the through rod 24 on the sliding frame 8 slides inside the fixing sleeve 9, thereby making the anti-slip disc 26 slide inside the fixing sleeve 9. When the decal is completed, the sliding frame 8 is directly pressed to make the sliding frame 8 and the fixing sleeve 9 closely contact, so that the clamping block 6 shrinks into the positioning plate 21. After no longer being fixed by the clamping block 6, under the action of the first spring 4, the support rod 1 drives the positioning plate 21 directly back to the origin, completes the reset, and waits for the decal of the next helmet.
[0027] In this embodiment, the rotating assembly includes a bracket 10, a rotating disk 11 and a roller 12. During use, when the clamping mechanism and the positioning mechanism are operating normally, the rotating disk 11 installed on the bracket 10 is rotated, and the fixed sleeve 9 and the clamping sleeve 5 also rotate accordingly. While the rotating disk 11 rotates, the external plate 13 on the rotating disk 11 contacts the roller 12 installed in the internal placement groove 14 of the bracket 10, thereby making the rotation easier. Example 2
[0028] To sum up, when in use, the helmet is placed directly on the first contact block 18. At this time, the helmet is pressed, and the support rod 1 slides inside the clamping sleeve 5 under the action of pressure, and the first spring 4 fixedly connected to the receiving plate 20 is compressed inside the clamping sleeve 5, and the receiving plate 20 slides in the first slide groove 15, so that the connecting rod 2 applies pressure to the sliding plate 3, so that the sliding plate 3 slides in the second slide groove 16 on the clamping sleeve 5, so that the second contact block 19 on the sliding plate 3 contacts the inside of the helmet, and the positioning plate 21 also begins to slide inside the third slide groove 17 under the movement of the support rod 1, so that the card block 6 enters the fixed sleeve 9. After contacting the fixed sleeve 9, the card block 6 is compressed due to its shape, so that the card block 6 is compressed into the positioning plate 21, and at the same time the second spring 7 is also compressed. When the card block 6 contacts the extrusion block 25 on the sliding frame 8, the compressed second spring 7 begins to release its elastic potential energy, pushing the card block 6 out of the positioning After the clamping mechanism and the positioning mechanism are in normal operation, the rotating disk 11 installed on the bracket 10 is rotated, and the fixing sleeve 9 and the clamping sleeve 5 are also rotated accordingly. When the rotating disk 11 rotates, the external plate 13 on the rotating disk 11 contacts the roller 12 installed in the placement groove 14 inside the bracket 10, thereby making the rotation easier. When the decal is completed, the sliding frame 8 is directly pressed to make the sliding frame 8 and the fixing sleeve 9 closely contact, so that the block 6 is retracted into the positioning plate 21. After it is no longer fixed by the block 6, under the action of the first spring 4, the support rod 1 drives the positioning plate 21 to directly return to the origin, completes the reset, and waits for the decal of the next helmet.
