[0020] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, but should not be construed as limiting the present utility model.

[0021] Please refer to Figures 2 to 6 , Figure 2 Schematic diagram of the welding of the lip plate and the baffle plate, and the support foot and the ejector rod in the adjusting plate of the present utility model; Figure 3 Schematic diagram of the connection of the lip plate, the bridge plate and the support foot in the adjusting plate of the present utility model; Figure 4 Schematic diagram of the lower end of the support foot contacting the guide plate in the adjusting plate of the present utility model; Figure 5 Schematic diagram of the states of various components when the adjusting plate of the present utility model is lowered to the lowest point; Figure 6 Schematic diagram of the contact state between the ejector rod and the footrest when the adjusting plate of the present utility model is lowered.

[0022] The utility model provides an automatic lowering mechanism for an adjusting plate, which includes a bridge plate 5 and an automatic adjustment component. The automatic adjustment component includes a lip plate 1, a baffle plate 2, a support foot 3, a push rod 4, a support frame 6, a guide plate 7 and a torsion spring 8. Through the foregoing solution, the problem that when the support foot 3 is lowered, it is necessary to manually pull the chain welded to the support foot 3 to drive the support foot 3 to retract to complete the lowering action, which requires two people to operate simultaneously, is time-consuming and laborious, and the chain often breaks can be solved. It can be understood that in the foregoing solution, when the height of the adjusting plate needs to be adjusted, the baffle plate 2 and the lip plate 1 are fixedly connected by welding, and the push rod 4 and the support foot 3 are fixedly connected by welding; the lip plate 1 is connected to the bridge plate 5 through a long shaft, and the support foot 3 is connected to the bridge plate 5 through a support foot 3 pin. When the adjusting plate rises, the support foot 3 leaves the groove of the support frame 6. When the lip plate 1 opens, the baffle plate 2 pushes the push rod 4, forcing the support foot 3 to rotate inward. When the bridge plate 5 descends without an obstacle, the lower end of the support foot 3 falls onto the guide plate 7 to complete the lowering action. After the forklift operation is completed, the adjusting plate is retracted to the horizontal state. While the bridge plate 5 rises, the lip plate 1 automatically descends and retracts. The baffle plate 2 leaves the push rod 4, and the support foot 3 automatically returns to the vertical state and returns to the groove of the support frame 6 when falling. This lowering structure controls the angle of the support foot 3 when the lip plate 1 opens and closes through the baffle plate 2 and the push rod 4 to complete the lowering action, saving the labor that needs to be added during the original lowering process, and only one person is required to operate. Moreover, on the basis of the original adjusting plate, materials such as chains, pull rings, pull ring seats, small wheels and limit rings are omitted, and at the same time, the need for later maintenance is reduced. Thus, the defects of the original structure are overcome, the number of welding points that were originally necessary is reduced, the complicated parts are reduced, and the chain and guide wheel mechanism are omitted, effectively solving the problem that when the support foot 3 is lowered, it is necessary to manually pull the chain welded to the support foot 3 to drive the support foot 3 to retract to complete the lowering action, which requires two people to operate simultaneously, is time-consuming and laborious, and the chain often breaks.

[0023] For this specific embodiment, the lip plate 1 is rotatably connected to the bridge plate 5 and is located below one end of the bridge plate 5. The baffle plate 2 is fixedly connected to the lip plate 1 and is located on the side of the lip plate 1 close to the bridge plate 5, and the baffle plate 2 is arranged below the bridge plate 5. The baffle plate 2 is welded to the lip plate 1, and the push rod 4 is welded to the support foot 3; the lip plate 1 is connected to the bridge plate 5 through a long shaft, and the support foot 3 is connected to the bridge plate 5 through a support foot 3 pin. When the lip plate 1 opens, it forces the support foot 3 to rotate inward, and the lower end of the support foot 3 falls onto the guide plate 7, and the self-weight of the adjusting plate causes the support foot 3 to continue to rotate inward until the lowest point.

[0024] Wherein, the supporting leg 3 is rotatably connected to the bridge plate 5, is located below the bridge plate 5, and the supporting leg 3 is arranged on one side of the lip plate 1. One end of the ejector rod 4 is fixedly connected to the supporting leg 3 and is located above one side of the supporting leg 3 close to the lip plate 1. The ejector rod 4 is arranged below the bridge plate 5, and the other end of the ejector rod 4 is arranged on one side of the lip plate 1 close to the supporting leg 3.

[0025] Secondly, the support frame 6 is arranged below the supporting leg 3, and the support frame 6 is a functional structural component for installing and supporting the supporting leg 3.

[0026] Meanwhile, the guide plate 7 is detachably connected to the support frame 6 and is located on one side of the support frame 6. The guide plate 7 is arranged on the side of the support frame 6 away from the lip plate 1, and the guide plate 7 is an auxiliary component for guiding the supporting leg 3 to move to a specified position.

[0027] In addition, the torsion spring 8 is detachably connected to the supporting leg 3 and is located at one end of the supporting leg 3 away from the bridge plate 5. The torsion spring 8 is arranged on one side of the supporting leg 3, and the torsion spring 8 is also vertically arranged with the supporting leg 3. The baffle 2 is welded on the lip plate 1, and the L-shaped ejector rod 4 is fixed on the supporting leg 3 through the torsion spring 8 and the support leg pin; the lip plate 1 and the bridge plate 5 are connected by a long shaft, the supporting leg 3 and the bridge plate 5 are connected by a support leg pin. When the lip plate 1 is opened, the supporting leg 3 rotates inwardly, and the lower end of the supporting leg 3 falls onto the guide plate 7. The supporting leg 3 continues to rotate inwardly by the self-weight of the adjusting plate. When the L-shaped ejector rod 4 contacts the support frame 6, the L-shaped ejector rod 4 starts to rotate clockwise relative to the supporting leg 3 until the lowest point.

[0028] When using the present utility model to adjust the height of the adjusting plate, the baffle 2 and the lip plate 1 are fixed by welding, and the ejector rod 4 and the support foot 3 are fixed by welding; the lip plate 1 is connected to the bridge plate 5 through a long shaft, and the support foot 3 is connected to the bridge plate 5 through a support foot 3 pin. When the adjusting plate rises, the support foot 3 leaves the groove of the footrest 6. When the lip plate 1 opens, the baffle 2 pushes the ejector rod 4, forcing the support foot 3 to rotate inward. When the bridge plate 5 descends without an obstacle, the lower end of the support foot 3 falls onto the guide plate 7 to complete the lowering action. After the forklift operation is completed, the adjusting plate is retracted to the horizontal state. While the bridge plate 5 rises, the lip plate 1 automatically descends and retracts. The baffle 2 leaves the ejector rod 4, and the support foot 3 automatically returns to the vertical state and falls back into the groove of the footrest 6 when descending. This lowering structure controls the angle of the support foot 3 when the lip plate 1 opens and closes through the baffle 2 and the ejector rod 4 to complete the lowering action, saving the labor that needed to be added during the original lowering process. It only requires one person to operate. Moreover, on the basis of the original adjusting plate, materials such as chains, pull rings, pull ring seats, small wheels, and limit rings are eliminated, and at the same time, the need for later maintenance is reduced. Thus, the disadvantages of the original structure are overcome, the number of welding points that were originally necessary is reduced, the complicated parts are reduced, and the chain and guide wheel mechanism are eliminated. It effectively solves the problem that when the support foot 3 is lowered, it is necessary to manually pull the chain welded to the support foot 3 to drive the support foot 3 to retract to complete the lowering action, which requires two people to operate simultaneously, is time-consuming and laborious, and often has problems with the chain breaking.
