detailed description

Below in conjunction with accompanying drawing, semi-trailer supporting leg of the present utility model is further described:

Embodiment: As shown in Figures 1 to 2, the outrigger of the semi-trailer of the present invention includes a fixed seat 1, a support 2 and a fixed wing plate 3, the above-mentioned fixed seat 1 is socketed on the support 2, and the above-mentioned fixed wing plate 3 is installed On the back of the upper end of the fixed base 1 , a lifting adjustment mechanism 4 is arranged inside the fixed base 1 and the support 2 .

Above-mentioned lifting adjustment mechanism 4 comprises connecting rod 41, transmission gear 42, helical gear 43, backing plate 44, leading screw 45, fixed nut 46 and support plate 47, and above-mentioned transmission gear 42 is installed in the holder 1, and above-mentioned transmission gear 42 Mesh with the helical gear 43, the helical gear 43 is connected with the lead screw 45, the backing plate 44 is welded in the fixed seat 1, the lead screw 45 is sleeved with the backing plate 44, and the support plate 47 is clamped in the support 2 , the above-mentioned fixing nut 46 is sleeved and installed in the support plate 47 , and the lower end of the above-mentioned lead screw 45 is screwed and matched with the fixing nut 46 .

The lower end of the backing plate 44 is provided with a bearing 5 cooperating with the lead screw 45, which can reduce the wear of the lead screw during rotation.

Both ends of the above-mentioned support plate 47 are provided with clamping blocks 6, and the above-mentioned clamping blocks 6 are clamped in grooves on the inner wall of the support 2, so that the support plate 47 is connected more firmly and has higher strength.

A baffle 7 is welded inside the support 2 , and the baffle 7 is arranged above the fixing nut 46 to prevent the fixing nut 46 from being displaced and affecting the normal operation of the lead screw 45 .

The above-mentioned fixing seat 1, supporting seat 2 and support plate 47 are all made of aluminum alloy, which makes the whole device lighter in weight and saves production cost.

During the use of the semi-trailer leg of this embodiment, the fixed wing plate 3 is fixed on the car box of the semi-trailer, and the transmission gear 42 is driven to rotate by rotating the connecting rod 41, which further drives the helical gear 43 meshed with the transmission gear 42 to rotate. The helical gear 43 rotates and simultaneously drives the lead screw 45 to rotate to produce relative displacement. Since the helical gear 43 is fixed and rotates without displacement change, the lead screw 45 moves up and down relative to the helical gear, and further, the fixed nut 46 screwed with the lead screw 45 is synchronized up and down. move, and further drive the support plate 47 and the support 2 to move up and down to achieve the purpose of adjusting the height; in addition, the blocks 6 at both ends of the support plate 47 are clamped in the grooves on the inner wall of the support 2, and its structure is further strengthened by welding Intensity, its strength is higher, in the process that leading screw 45 drives support plate 47 to move up and down, the situation that support plate 47 disengages because of strong force will not occur, so that the whole device can be used safely and normally.

The outrigger of the semi-trailer of the utility model has the advantages of simple structure, high supporting strength, firmness and durability, free adjustable height and convenient use.

The above is only the preferred embodiment of the utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and modifications can also be made. And retouching should also be regarded as the protection scope of the present utility model.
