Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following description will make a detailed description of embodiments of the present invention with reference to the accompanying drawings and examples.
The present embodiment provides a front guide supporting device, which is structurally shown in fig. 1. The front guide supporting device comprises an upper body 4, a lower body 5, a crank handle 1, a bevel gear 2, a screw nut 3, a bolt 6, a rotating shaft 7 and a universal wheel 8. Wherein, the upper body 4 comprises a fixed part and a movable part, the lower end of the fixed part is connected with the upper end of the lower body 5 through a rotating shaft 7 and is fixed through a bolt 6 when in use. The lower part of the lower body 5 is provided with universal wheels 8 for supporting. The upper end of the fixing part is connected with a nut. The movable part is sleeved outside the fixed part, the crank 1 extends into the movable part from the side surface of the upper end of the movable part and is connected with a bevel gear 2 positioned in the movable part, the bevel gear 2 is connected with a lead screw positioned in the movable part, and the lead screw is connected with a nut at the upper end of the fixed part.
When in use, the bolt 6 is inserted into the bolt hole between the upper body 4 and the lower body 5, so that the upper body and the lower body are fixed into a whole, the universal wheel 8 is used for supporting on the ground, the bevel gear 2 drives the screw rod to rotate relative to the nut by rotating the crank 1, so that the lower body 5 is vertically lifted, and the height of the front guiding support device is changed, as shown in figure 2. When the trailer is folded, the bolt 6 is pulled out, the rocking handle 1 is shaken, the lead screw is driven to rotate through the bevel gear 2, so that the moving part of the upper body is lowered to the lowest position, then the rocking handle 1 is pulled out, the lower body 5 can rotate around the rotating shaft 7 for 90 degrees and then is folded to the side, and after the folding, the hanging lug of the lower body 5 is fixed on the trailer body through the bolt 6, as shown in figure 3.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
