Description

Technical Field

[0001] The utility model relates to a material rack, in particular to an automatic anti-jump device relying on its own weight. Background Art

[0002] Traditional material racks use limit blocks to press on the parts placed on the material rack to prevent the parts from jumping. The limit blocks are either fixed directly on the material rack, or installed on a flip structure and the flip structure is used to screw the limit blocks in or out. Regardless of the method, there are various problems during use and it is inconvenient to use. Utility Model Content

[0003] The utility model proposes an automatic anti-jump device that relies on its own weight. Based on a connecting rod support device, a pressure plate is designed. The pressure plate is connected to the connecting rod and moves up and down with the connecting rod. The upward swing releases the part and the downward swing presses on the part. When the pressure plate presses on the part, the weight of the part is converted into downward pressure of the pressure plate on the part under the transmission of the connecting rod, so that the anti-jump effect is better.

[0004] The technical solution of this utility model:

[0005] An automatic anti-jump device relying on its own weight, the anti-jump device cooperates with a supporting device, the supporting device includes a supporting plate, a plurality of supporting plates are hingedly mounted on a material rack body, each supporting plate is arranged up and down, adjacent supporting plates are provided with a connecting rod, the connecting rod is hinged to the upper supporting plate, the connecting rod is connected to the lower supporting plate through a guide rod and a guide hole, the guide rod is mounted on the supporting plate, the guide hole is provided on the connecting rod, the guide rod is restricted in the guide hole, when the upper supporting plate is opened or closed, the lower supporting plate is in an open state, The connecting rod moves up and down accordingly, the guide rod moves in the guide hole, and a part is supported on the next opened support plate; the anti-jump device includes a pressure plate, which is hinged on the material rack body, located above the next support plate, and connected to the connecting rod through a limit pin and a limit hole. The limit pin is installed on the connecting rod, and the limit hole is set on the pressure plate. The limit pin is restricted in the limit hole. When the upper support plate is opened or closed, the limit pin moves in the limit hole, and the pressure plate swings to release the part or swings down to press on the part.

[0006] The pressing plate and the next supporting plate are fixed on a hinge shaft and connected to the material rack body through the hinge shaft;

[0007] A torsion spring is mounted on the hinge shaft, with its two ends respectively resting on the material rack body and the pressure plate. The torsion spring applies an elastic force to the pressure plate to cause it to swing downward, so that the pressure plate can swing downward smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] like Figure 1-3 As shown, an automatic anti-jump device relying on its own weight is matched with a supporting device. The supporting device includes a supporting plate 1. Several supporting plates 1 are hingedly mounted on a material rack body 2. Each supporting plate 1 is arranged up and down. Adjacent supporting plates 1 are provided with connecting rods 3. The connecting rods 3 are hinged to the upper supporting plate. The connecting rods 3 are connected to the lower supporting plate through guide rods 4 and guide holes 5. The guide rods 4 are mounted on the supporting plate 1. The guide holes 5 are provided on the connecting rods 3. The guide rods 4 are restricted in the guide holes 5. The anti-jump device includes a pressing plate 6. The pressing plate 6 is hinged to the rack body 2, located above the next supporting plate and connected to the connecting rod 3 via a limit pin 7 and a limit hole 8. The limit pin 7 is mounted on the connecting rod 3, and the limit hole 8 is provided on the pressure plate 6, with the limit pin 7 being restricted within the limit hole 8. The pressure plate 6 and the next supporting plate are fixed on a hinge shaft 9 and connected to the rack body 2 via the hinge shaft 9. A torsion spring 10 is fitted onto the hinge shaft 9, with its two ends respectively resting on the rack body 2 and the pressure plate 6, exerting an elastic force on the pressure plate 6 to cause it to swing downward.

[0013] When the upper support plate is opened or closed, the next support plate is in the open state, the connecting rod 3 moves up and down accordingly, the guide rod 4 moves in the guide hole 5, the part 11 is supported on the opened next support plate, the limit pin 7 moves in the limit hole 8, the pressure plate 6 swings up to release the part 11 or swings down to press on the part 11; when the next support plate is closed, the pressure plate 6 is placed on the guide rod 4.

[0014] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
