[0001] The utility model relates to the technical field of transportation equipment, in particular to a guide rod structure. Background Art
[0002] The loading and unloading board at the rear of the transporter is a lifting and unloading device installed at the rear of trucks and various vehicles. The loading and unloading board can easily lift the goods from the ground and place them on the truck, or unload them from the truck without the use of cranes or manual handling equipment, thereby greatly improving the loading and unloading efficiency. By improving the loading and unloading efficiency, a lot of labor costs and time costs can be saved. At the same time, the loading and unloading board can also prevent the goods from being damaged, broken or scattered during the falling process. Especially for fresh, fragile or high-value goods, the use of the tailboard can better protect them.
[0003] In the prior art, in order to save space, the end of the loading and unloading board behind the transport vehicle usually carries a flip-foldable flap. During use, when the loading and unloading board needs to be extended to the ground, the flap is manually extended to the same level as the loading and unloading board, and then the loading and unloading board and the flap are manually rotated downward so that the end of the flap is placed on the ground. Then the flap and the loading and unloading board form a slope, and the goods can be loaded and unloaded along the slope; when use is completed, the staff will rotate and flip the loading and unloading board and the flap to the initial state to meet the needs of loading and unloading goods.
[0004] However, the loading and unloading plates and flaps are often large in size, which makes it laborious and troublesome to rotate and flip them manually, and it is easy to get injured due to improper operation. Based on this, the utility model is committed to providing a guide rod mechanism to enable the loading and unloading plates and flaps at the rear of the transport vehicle to be automatically extended and folded.

[0026] A linkage mechanism consisting of a guide rod 400, a push rod 500 and an oil cylinder 600 is provided between the two outer sides of the two connecting plates 800 and the movable flap 200 near the loading and unloading plate 100, wherein the guide rod 400 is a straight long rod, one end of which is hingedly connected to a hinge point in the middle of the connecting plate 800, and the other end is hingedly connected to the push rod 500, and the push rod 500 is composed of two short rods connected at the ends, and the angle between the two short rods is an obtuse angle, and the obtuse angle direction is upward; the end of the guide rod 400 away from the connecting plate 800 is hinged to the connection between the two short rods, that is, it is hinged to the center of the push rod 500; one end of the push rod 500 is hinged to the outer side of one end of the loading and unloading plate 100 near the rotating shaft 300, and the other end is slidably arranged in the slide groove 201 through a slider.
[0027] A hinge is installed on the lower side of the guide rod 400, the extended end of the cylinder 600 is hinged to the hinge on the lower side of the guide rod 400, and the other end is connected to the lowest hinge point of the connecting plate 800; a support leg 900 is also installed on the lower side of the loading and unloading plate 100, and the support leg 900 is supported on the ground.
[0028] The working principle of this utility model:
[0029] See also Figure 2 When not in use, the guide rod structure is in a propped-up state, and the movable flap 200 therein is folded to the back side of the loading and unloading plate 100; when the guide rod structure is used, the linkage mechanism is driven to move by the extension and retraction of the oil cylinder 600, thereby driving the movable flap 200 to flip around the rotation axis 300; when the movable flap 200 needs to be extended, the oil cylinder 600 extends forward to drive the guide rod 400 to push forward, and the guide rod 400 drives the push rod 500 to slide in the slide groove 201, thereby driving the movable flap 200 to flip counterclockwise to the same plane as the loading and unloading plate 100, and at the same time, the loading and unloading plate 100 flips downward clockwise, the support legs 900 are supported on the ground, and the end of the movable flap 200 extends to the ground, so that goods can be loaded and unloaded onto the vehicle through the loading and unloading plate 100 and the movable flap 200.
[0030] When the movable flap 200 needs to be retracted, the oil cylinder 600 retracts and drives the push rod 500 to slide in the slide groove 201. At this time, the movable flap 200 flips down and folds clockwise, and the loading and unloading plate 100 is supported upward until the movable flap 200 flips to the back of the loading and unloading plate 100, and the folding process is completed; in the process of extending and folding the movable flap 200, the push rod 500 will slowly slide along the slide groove 201 under the action of the guide rod 400, so the movable flap 200 can slowly fall or fold up, which can prevent the movable flap 200 from falling or folding directly under the action of gravity, causing impact and damage to other structures or operators; and the extension and folding of the movable flap 200 can be controlled directly by controlling the oil cylinder 600, without manual assistance, saving time and effort, and being convenient and fast.
