[0028] Example 1

[0029] Reference Figures 1-2 , which is the first embodiment of the present utility model, provides a rotation adjustment mechanism.

[0030] The storage assembly 100 is used to control the expansion or closing of the protective shed, thereby facilitating cleaning, ventilation, equipment hoisting and maintenance of the protective shed. The supporting sleeve 101 is used to control the rotation function. On one side of the supporting sleeve 101, a protective strip 102 is rotatably provided. The protective strip 102 can rotate along the supporting sleeve 101. An adjustment rod 103 is provided on the top of the protective strip 102, and an extension plate 104 is extended from the top of the supporting sleeve 101. The other end of the adjustment rod 103 is connected to the extension plate 104 and can slide linearly along the surface of the extension plate 104, facilitating the movement of the protective strip 102 and making it more stable and safe.

[0031] The auxiliary component 200 is used to ensure that the protective strip 102 does not require human maintenance during movement, and will not rotate and reset even if it is released, making it easy to operate. A control shaft 201 is rotatably provided on the inner wall of the bearing sleeve 101. The control shaft 201 is directly connected to the protective strip 102. When the control shaft 201 starts to rotate, it can drive the protective strip 102 to rotate. A mating wheel 202 is fixedly provided on one side of the control shaft 201. The mating wheel 202 can rotate synchronously with the movement of the control shaft 201. A locking unit 203 is fixedly provided between the mating wheel 202 and the control shaft 201. The locking unit 203 itself is fixedly connected to the inner wall of the bearing sleeve 101 and meshes with the mating wheel 202 to prevent the mating wheel 202 from rotating under the gravity of the protective strip 102, ensuring that the mating wheel 202 can only rotate in one direction.

[0032] The support assembly 300 provides protection for the entire protective shed installation and the sand mixing device. A stabilizing side panel 301 is fixed beneath the support sleeve 101. A reinforcement beam 302 is fixed between the stabilizing side panels 301 to ensure the shed's secure installation. A buffer unit 303 is located within the extension plate 104 to slow the descent of the adjustment rod 103, specifically the closing and lowering of the protective slats 102. This ensures a safer return of the protective slats 102 and prevents significant impact and wear under gravity.

[0033] Example 2

[0034] Reference Figures 1 to 4 , which is the second embodiment of the present invention, is based on the previous embodiment, but differs in that the structure of the storage component 100 and the matching structure of the auxiliary component 200 are further optimized.

[0035] A rotation adjustment slot 101a is fixedly provided on one side of the support sleeve 101, along which the protective slats 102 can slide. The protective slats 102 are fixedly connected to the control shaft 201, so that when the control shaft 201 rotates, they can drive the protective slats 102 to rotate along the rotation adjustment slot 101a. A pull slot 101b is fixedly provided at the bottom of the support sleeve 101, facilitating operator operation. The outer wall of the control shaft 201 is provided with a control cord 201a, and a pull rod 201a-1 is fixedly provided at the end surface of the control cord 201a. The pull rod 201a-1 is located outside the pull slot 101b and can be extended to meet operational requirements. Pulling the pull rod 201a-1 rotates the control cord 201a, ultimately causing the control shaft 201 to rotate with the protective slats 102, opening the protective shed.

[0036] The locking unit 203 is located between the control shaft 201 and the mating wheel 202. The surface of the locking unit 203 is elastically provided with a one-way torsion bar 203a. The one-way torsion bar 203a itself is engaged with the mating wheel 202. When the mating wheel 202 starts to rotate, the one-way torsion bar 203a can only be rotated in a single direction. Under the structural limitation of the one-way torsion bar 203a itself, it can prevent the mating wheel 202 from reversing, thereby preventing the control shaft 201 and the protective strap 102 from reversing, providing a one-way locking limit function. On the other side of the one-way torsion bar 203a, a toggle rod 203a-1 is fixedly provided. When the toggle rod 203a-1 is pulled, it can drive the one-way torsion bar 203a to perform a small horizontal displacement, thereby misaligning with the mating wheel 202. The mating wheel 202, which has lost the restriction of the one-way torsion bar 203a, can now reset under the action of the gravity of the protective strip 102 and rotate in the opposite direction. The protective strip 102 can return to its original position autonomously, and the protective shed is closed.

[0037] An unlocking slot 101c is fixedly provided on one side of the pulling slot 101b, and an unlocking rod 101c-1 is slidably provided at the bottom of the unlocking slot 101c. The bottom of the unlocking rod 101c-1 passes through the unlocking slot 101c and is fixedly connected to the toggle rod 203a-1. Pulling the unlocking rod 101c-1 from the outside can drive the toggle rod 203a-1 and the mating wheel 202 to be dislocated, and the protective board 102 can return to its initial position autonomously, and the protective shed is closed.

[0038] A rotating groove 102a is provided on the top of the protective strap 102, and a matching shaft 102a-1 is fixedly provided on the inner wall of the rotating groove 102a. One end of the adjusting rod 103 is rotatably sleeved on the outer wall of the matching shaft 102a-1. An extension plate 104 is fixedly provided on the top of the storage component 100, and a docking groove 104a is provided on the surface of the extension plate 104. Limiting grooves 104a-1 are provided on both sides of the inner wall of the docking groove 104a to cooperate with the other end of the adjusting rod 103. The other end of the adjusting rod 103 is provided with cylindrical protrusions on the left and right to enter the limiting groove 104a-1, ensuring that the overall operation of the adjusting rod 103 is stable and can slide straightly along the limiting groove 104a-1.

[0039] Example 3

[0040] Reference Figures 1 to 8 , which is the third embodiment of the present utility model, and this embodiment is based on the above embodiment.

[0041] The support assembly 300 provides protection for the installation of the entire protective shed and the sand mixing device. A stabilizing side plate 301 is fixedly provided below the bearing sleeve 101, and a reinforcing beam 302 is fixedly provided between the stabilizing side plate 301 and the stabilizing side plate 301 to ensure the stable installation of the protective shed. The buffer unit 303 is arranged in the extension plate 104, on one side of the limiting groove 104a-1, and is connected with the limiting groove 104a-1. The top of the buffer unit 303 is slidingly provided with an adjusting piston 303a. The protrusions at both ends of the adjusting rod 103 are in the limiting groove 104a-1 and are fixedly connected with the adjusting piston 303a. When the adjusting rod 103 moves linearly along the limiting groove 104a-1, it can also drive the adjusting piston 303a to move linearly.

[0042] An air hole 304 is fixedly opened on the surface of the extension plate 104, and the air hole 304 is connected to the bottom of the buffer unit 303. Since the size of the air hole 304 is very small, the adjusting piston 303a needs to overcome the corresponding air pressure while following the downward movement of the adjusting rod 103, thereby limiting the descending speed of the adjusting rod 103, thereby limiting the rotation and falling speed of the protective strip 102, making the reset safer and preventing large collisions and wear under the action of gravity.
