DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1In this embodiment, an A-type support leg for a special snow vehicle includes a connecting member 1 and two inclined receiving tubes 2. The two receiving tubes 2 are fixed on the left and right sides of the connecting member 1. The A-type support leg makes the support leg more stable. The lower sides of the two receiving tubes 2 are provided with support blocks 3. The inner cavity of the receiving tube 2 is provided with a height adjustment mechanism 4 for adjusting the height of the support block 3. Support mechanisms 5 for improving the stability of the special vehicle are provided on both sides of the support block 3.

[0026] See also Figures 2 to 5 To improve support stability on snowy terrain in alpine regions, the support mechanism 5 in this embodiment includes two drive plates 501 located on the left and right sides of the support block 3. Mounting plates 502 are fixed to the lower ends of the drive plates 501. A connecting plate 503 is fixed between the two mounting plates 502. A row of slotted teeth 504 is formed on the front side of the connecting plate 503. The front side of the connecting plate 503 also has a row of U-shaped grooves, with slotted teeth 504 formed between each pair of adjacent U-shaped grooves. The U-shaped grooves can be, but are not limited to, square or arcuate, and can be configured based on actual needs.

[0027] Specifically, the support block 3 is provided with a first central hole extending horizontally therethrough and at least two first adjustment holes; the at least two first adjustment holes are spaced apart with the first central hole as the center. Each drive plate 501 is provided with a second central hole and at least two second adjustment holes, with the at least two second adjustment holes spaced apart with the second central hole as the center. By manually rotating the drive plate 501 and keeping the second central hole and the first central hole aligned at all times, the second adjustment holes on the drive plate 501 can be aligned with different first adjustment holes. Rotating the drive plate 501 drives the connecting plate 503 to rotate relative to the support block 3, thereby adjusting the angles of the splines 504 of the connecting plate 503 relative to the ground.

[0028] More specifically, the support mechanism 5 further comprises at least two insertion rods 506, one of which is rotatably inserted into the first center hole and the second center hole of each drive plate 501, and the other at least one insertion rod 506 is detachably inserted into a first adjustment hole and a corresponding second adjustment hole on each drive plate 501; as the insertion rod 506 is selectively inserted into different first adjustment holes and corresponding second adjustment holes on the drive plate 501, the angle between the connecting plate (503) and the bottom end of the support block 3 is different. The two drive plates 501 are rotatably fixed to the support block 3 by one insertion rod 506, and then the drive plate 501 is rotated. When the connecting plate 503 is rotated to the required angle and the two second adjustment holes on the two drive plates 501 are aligned with one first adjustment hole, one insertion rod 506 is used to insert one first adjustment hole and two aligned second adjustment holes to achieve the position fixation of the drive plates 501. Of course, multiple insertion rods 506 can also be used to insert multiple corresponding first adjustment holes and second adjustment holes respectively to further improve the fixing stability of the drive plates 501. When the connecting plate 503 is rotated to a suitable angle with the supporting block 3, the inserting teeth 504 are facing the ground or tilted toward the ground, which facilitates insertion into the snowy ground, thereby improving the stability of the vehicle body support.

[0029] For example, two second adjustment holes are provided, with the two second adjustment holes and the center hole on the same drive plate 501 arranged in an equilateral triangle. Two first adjustment holes are provided, with the two first adjustment holes and the first center hole arranged in an equilateral triangle. When the two first adjustment holes are aligned with the two second adjustment holes on the drive plate 501, the connecting plate 503 is parallel to the ground, i.e., in a stowed state, to avoid interference with the external environment. When needed, the rod 506 connecting the first and second adjustment holes is removed, the drive plate 501 is rotated so that only one first adjustment hole is aligned with a second adjustment hole on each drive plate 501, and then the rod 506 is inserted to secure the drive plate 501, completing the angle adjustment of the connecting plate 503. At this point, the connecting plate 503 forms a predetermined angle with the ground. Of course, in other embodiments, multiple first or second adjustment holes may be provided, such as three, four, or five, to achieve adjustment and fixation of the connecting plate 503 at different angles, depending on actual needs.

[0030] The outer diameter of the insertion rod 506 is adapted to the inner diameters of the first center hole, the second center hole, the first adjustment hole, and the second adjustment hole.

[0031] Preferably, the outer contour of the driving plate 501 is a triangle, and the driving plate 501 rotates on the left and right sides of the support block 3. The driving plate 501 has a top corner and a corresponding bottom edge, and the second center hole is located at the top corner of the driving plate 501.

[0032] Furthermore, the support mechanism 5 also includes a stopper 508. Both ends of the insertion rod 506 are provided with a stopper hole 507 extending radially through the insertion rod 506. One stopper 508 is removably plugged into one of the stopper holes 507. In this embodiment, the outer diameter of the stopper 508 matches the inner diameter of the stopper hole 507, and the length of the stopper 508 is greater than the dimensions of the inner cavities of the first center hole, the second center hole, the first adjustment hole, and the second adjustment hole. By inserting the stopper 508 into the stopper hole 507, the insertion rod 506 can be effectively prevented from falling out of the first center hole, the second center hole, the first adjustment hole, or the second adjustment hole. This effectively limits the axial position of the insertion rod 506, thereby improving the reliability of the support mechanism 5. Furthermore, the structure is simple, the cost is low, and the operation is convenient.

[0033] Exemplarily, the stopper 508 is a U-shaped clip, which reduces the possibility of the stopper 508 falling from the stopper hole 507. Preferably, the U-shaped clip has two clips, one of which is straight to facilitate insertion into the stopper hole 507, and the other clip is wavy to further reduce the possibility of the stopper 508 falling from the stopper hole 507.

[0034] See also Figure 6 In order to adjust the support height of the vehicle body, the height adjustment mechanism 4 in this embodiment includes an electric push rod 401 arranged in the inner cavity of the receiving tube 2, a mounting bracket 402 is fixed to the middle part of the outer surface of the electric push rod 401, and the piston rod of the electric push rod 401, i.e., the driving end, is fixed to an inner tube 403.

[0035] The left and right sides of the mounting bracket 402 are fixedly connected to the opposite left and right side walls of the inner cavity of the receiving tube 2, respectively. The end of the electric push rod 401 facing away from the driving end is fixed to the inner top wall of the receiving tube 2, and the lower surface of the inner tube 403 is fixed to the support block 3. After the connector 1 is fixed to the special-purpose vehicle, the height of the inner tube 403 can be adjusted via the height adjustment mechanism 4. By activating the two electric push rods 401, the piston rods of the electric push rods 401 move downward, thereby pushing the inner tube 403 downward, and thus the support block 3 downward, thereby adjusting the support height of the vehicle body. The inner tube 403 moves up and down within the inner cavity of the receiving tube 2.

[0036] It should be noted that the height of the inner cylinder 403 can be adjusted by utilizing the height adjustment mechanism 4 , thereby facilitating the user to adjust the support height of the vehicle body, thereby meeting the different needs of the users.

[0037] The working principle of the above embodiment is:

[0038] When using the special vehicle A-type support leg on snow in high-altitude and cold areas, the connecting piece 1 can be fixed to the special vehicle first. At this time, the height of the inner cylinder 403 can be adjusted by the height adjustment mechanism 4, and the two electric push rods 401 are started. The piston rods of the electric push rods 401 move downward, thereby pushing the inner cylinder 403 to move downward, and then the support block 3 moves downward, and the support height of the vehicle body can be adjusted. In order to improve the stability of the support, a plug that is fixedly connected to a first adjustment hole and a second adjustment hole on the two drive plates 501 can be fixed to the plug. The rod 506 is pulled out, and the drive plate 501 is rotated with the rod 506 connecting the first center hole and the second center hole as the center point. The rotation of the drive plate 501 drives the mounting plate 502 and the connecting plate 503 to rotate until the second adjustment hole on the drive plate 501 is aligned with the first adjustment hole on the support block 3. The rod 506 is then inserted, and the limiter 508 is inserted into the rod 506 to limit the rod 506. At this time, the teeth 504 of the connecting plate 503 are easy to insert into the snow surface, thereby improving the stability of the support. It should be noted that the order of adjusting the height of the support block 3 and the rotation of the connecting plate 503 is not limited. The height of the support block 3 can be adjusted first, or the rotation of the connecting plate 503 can be adjusted first.
