[0016] The technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-2As shown, a side space extension device for a special vehicle is shown. The special vehicle includes a vehicle body 1, a baffle 2 is hinged on the upper end of the side of the vehicle body 1, an electro-hydraulic push rod 3 is arranged on the lower end of the side of the vehicle body 1, and the free end of the piston rod of the electro-hydraulic push rod 3 is hinged to the middle part of the side edge of the baffle 2. A long strip-shaped cavity 4 is opened on the inner surface of the baffle 2, and a telescopic support rod 5 is hinged in the cavity 4. The telescopic support rod 5 includes a hollow circular tube 501 hinged in the cavity 4, and an internal thread is arranged in the hollow circular tube 501. A round rod 502 is screwed in the hollow circular tube 501. Two sets of ball seats 503 are arranged at the free end of the round rod 502, and a support plate 504 is hinged on the surface of each ball seat 503. When the telescopic support rod 5 is put down, the two support plates 504 are against the bottom surface and are arranged at 180 degrees. When the telescopic support rod 5 is retracted, the two support plates 504 are arranged in close contact. The adjustable setting of the support plate 504 is convenient for increasing the contact surface with the ground when the telescopic support rod 5 is opened, so as to maintain the stability of the placement of the telescopic support rod 5. A fixed plate group 6 and a movable plate group 7 are arranged at the bottom of the cavity 4 directly opposite the support plate 504. The fixed plate group 6 is arranged above the support plate 504, and the movable plate group 7 is arranged below the support plate 504. The movable plate group 7 includes a hinge seat 701 fixed in the cavity 4, and a limit plate 702 is connected to the hinge seat 701 through a hinge shaft, and a torsion spring 703 is sleeved on the hinge shaft. The coordinated setting of the fixed plate group 6 and the movable plate group 7 can fix the telescopic support rod 5 in the cavity 4. When it is needed, the limit plate 702 in the movable plate group 7 can be rotated, which is convenient to operate. There are two groups of telescopic support rods 5, and the two groups of telescopic support rods 5 are respectively arranged at the inner edge of the baffle 2.

[0018] When the utility model is working, the operator controls the electro-hydraulic push rod 3 to rotate the baffle plate 2 to a horizontal state, and after reaching the position, the telescopic support rod 5 in the cavity 4 is rotated to a vertical state. Due to the arrangement of the fixed plate group 6 and the movable plate group 7, the support plate 504 at the free end of the telescopic support rod 5 is limited, and the limit plate 702 in the fixed plate group 6 needs to be rotated toward the inside of the vehicle body 1, so that the free end of the telescopic support rod 5 can be rotated out of the cavity 4, so as to be in a vertical state. After the telescopic support rod 5 is in a vertical state, the round rod 502 is rotated so that the round rod 502 is displaced downward relative to the hollow circular tube 501 until the support plate 504 at the free end of the round rod 502 contacts the ground, thereby completing the construction of the outdoor space.

[0019] The present utility model is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present utility model, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present utility model.
