Description
Technical Field
[0001] The utility model relates to the technical field of unloading tools, in particular to a shock-proof loading and unloading device. Background Technique
[0002] The unloading slide is a tool used to slide goods from a high place to a low place for users to carry. When used in different working environments, the inclination amplitude is different. A large inclination amplitude results in a fast sliding speed, while a small inclination amplitude results in a slow sliding speed.
[0003] When using the unloading slide to unload goods, due to the large inclination amplitude, the sliding speed may be relatively fast, so the impact force will be relatively large. If the internal goods are relatively fragile, it may cause damage to the goods and result in some unnecessary losses. Content of the Utility Model

[0014] Compared with the prior art, the present utility model provides a loading and unloading device that can prevent impact, and has the following beneficial effects:
[0015] 1.

In this way, when the object slides, through the friction block, the object can move slowly, preventing the impact force during movement from being too large and causing damage to the object and resulting in some losses.
[0016] 2. For this loading and unloading device that can prevent impact, when the object moves to the bottom of the unloading slide, the object will squeeze the slope block, causing the hinge rod to move downward, and at the same time driving the other end of the connecting rod to move upward, which can make the object be lifted by the rubber plate, so as to play a role in reducing the impact force and enabling the object to stop more smoothly, preventing damage to the object caused by a large impact force.

Specific embodiments
[0024] As Figures 1-6 shown, the present utility model provides a technical solution: an impact-proof loading and unloading device, including a fixed frame 1, a roller 2 is rotatably installed inside the fixed frame 1 to facilitate the sliding of an object, a clamping mechanism 3 is arranged inside the fixed frame 1 to be able to adjust the rotation speed of the roller 2, and a buffering mechanism 4 is arranged on the left side of the fixed frame 1 to be able to stop the object when it reaches the end.
[0025] Specifically, the clamping mechanism 3 includes: an upper moving rod 31, a lower moving rod 32, a fixing plate 33, a clamping spring 34, an arc-shaped plate 35, a moving groove 36, a bidirectional telescopic rod 37, a fixed shaft 38, a return spring 39, a fixed block 310, a bolt 311, and a friction block 312. The upper moving rod 31 is slidably installed inside the fixing frame 1 to facilitate the installation of the fixing plate 33. The lower moving rod 32 is slidably installed inside the fixing frame 1 to facilitate the installation of the fixing plate 33. The top of the lower moving rod 32 is fixedly installed with the fixing plate 33 to facilitate the installation of the clamping spring 34. The right side of the fixing plate 33 is fixed with the clamping spring 34; to facilitate the installation of the arc-shaped plate 35. The arc-shaped plate 35, and the end of the clamping spring 34 away from the fixing plate 33 is fixedly installed with the arc-shaped plate 35, which can clamp the arc-shaped plate 35 and adjust the rotation speed of the roller 2. The fixing plate 33, the clamping spring 34, and the arc-shaped plate 35 are linearly arrayed with the top of the lower moving rod 32, which can clamp or release all the rollers 2. The right side of the arc-shaped plate 35 is attached to the outer wall of the roller 2. A moving groove 36 is formed in the front of the fixing frame 1 to facilitate the bidirectional telescopic rod 37 to drive the upper moving rod 31 and the lower moving rod 32 to move. The back of the upper moving rod 31 is hinged with the bidirectional telescopic rod 37; it can drive the upper moving rod 31 and the lower moving rod 32 to move in opposite directions. The fixed shaft 38, the middle of the bidirectional telescopic rod 37 is rotatably installed with the fixed shaft 38 to facilitate the rotation of the bidirectional telescopic rod 37. The back of the fixed shaft 38 is fixedly installed on the front of the fixing frame 1. The end of the bidirectional telescopic rod 37 away from the upper moving rod 31 is hinged to the back of the lower moving rod 32 for fixation. The left side of the moving groove 36 of the lower moving rod 32 is fixedly installed with the return spring 39, which can reset the bidirectional telescopic rod 37. The end of the return spring 39 away from the left side of the moving groove 36 is fixedly installed on the outer wall of the hinge column of the bidirectional telescopic rod 37 and the lower moving rod 32 for fixation. The front of the fixing frame 1 is fixed with the fixed block 310 to facilitate the installation of the bolt 311. The bolt 311 is threadedly connected to the through hole of the fixed block 310, which can drive the bidirectional telescopic rod 37 to rotate. The outer wall of the roller 2 is fixedly installed with the friction block 312, which can increase the friction force when the object moves and reduce the impact force.
[0026] Specifically, the deceleration mechanism 4 includes: a T-shaped groove 41, a hinge rod 42, an inclined block 43, a connecting rod 44, a support block 45, a cylinder 46, a rubber plate 47, and a moving spring 48. A T-shaped groove 41 is provided at the top of the fixed frame 1 to facilitate the up and down movement of the hinge rod 42. The hinge rod 42 is slidably installed inside the T-shaped groove 41 and can drive the other end of the connecting rod 44 to move up and down in the opposite direction when moving. The top of the hinge rod 42 is fixedly installed with an inclined block 43 to facilitate the object to press it into the T-shaped groove 41. The bottom of the hinge rod 42 is hinged with a connecting rod 44, which can drive the other end to move upward when the hinge rod 42 moves downward. A support block 45 is fixed on the left side of the fixed frame 1 to facilitate the fixation of the cylinder 46. There are two groups of support blocks 45, which are symmetrically distributed about the central axis of the front surface of the fixed frame 1 and are symmetrically distributed at the front and rear ends of the fixed frame 1, enabling the better fixation of the cylinder 46. The back surface of the support block 45 is fixedly installed with a cylinder 46 to facilitate the rotation of the center of the connecting rod 44 in the middle. The center through hole of the connecting rod 44 is rotatably installed on the outer wall of the cylinder 46 to facilitate the rotation of the connecting rod 44. The end of the connecting rod 44 away from the hinge rod 42 is hinged with a rubber plate 47, which can hold the object when it moves to the bottommost position, causing it to decelerate or stop. A moving spring 48 is fixedly installed at the bottom of the T-shaped groove 41, which can reset the inclined block 43 and the hinge rod 42 after the object is taken away. The end of the moving spring 48 away from the T-shaped groove 41 is fixedly installed at the bottom of the inclined block 43 for fixation.
[0027] Working principle: When the amplitude of the unloading slide is relatively large during unloading, the bolt 311 can be rotated to make the bolt 311 rotate in the fixed block 310. When the bolt 311 is loosened, the reset spring 39 can reset, causing the double telescopic rod 37 to rotate on the fixed shaft 38, driving the upper moving rod 31 and the lower moving rod 32 to move left and right in the moving groove 36. When the two moving rods move, the fixing plate 33 squeezes the clamping spring 34, enabling the arc-shaped plate 35 to clamp the roller 2, and the rotation speed of the roller 2 can be adjusted, thereby slowing down the rotation speed of the roller 2 and making the object descend more slowly. When the object slides on the surface of the roller 2 and touches the friction block 312, the object can move slowly. When the bolt 311 rotates in the reverse direction, the bolt 311 will squeeze the double telescopic rod 37 to reset, compressing the reset spring 39, and enabling the arc-shaped plate 35 not to clamp the roller 2, thus preventing excessive impact during movement from damaging the object and causing some losses.
[0028] When the object moves to the bottom of the unloading slide, the object presses against the inclined plane block 43, compressing the moving spring 48 and causing the hinge rod 42 to move downward in the T-shaped groove 41. At the same time, the connecting rod 44 rotates on the cylinder 46, causing the other end of the hinge rod 42 to move upward and raising the rubber plate 47. The object can be lifted by the rubber plate 47, which can play a role in reducing the impact force and enable the object to stop more smoothly. When the object is removed, the moving spring 48 drives the inclined plane block 43 to reset, causing the rubber plate 47 to return to its initial position, preventing damage to the object caused by a large impact force.
[0029] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
