[0024] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0025] Example 1

[0026] like Figure 1As shown, a special vehicle stowage and unfolding platform comprises a movable platform 3 and a fixed plate 4; one side of the movable platform 3 is connected to the fixed plate 4 via a hinge 5, and the middle part of the movable platform 3 is connected to the fixed plate 4 via a supporting push rod 2; a locking pin 1 is slidably connected to the movable platform 3, and a hinge seat 6 is provided on the fixed plate 4; a sleeve 7 and a push rod groove 8 are also provided on the movable platform 3, and a retaining ring 9 is provided on the sleeve 7.

[0027] A stop pin 10 is provided at one end of the locking pin 1, and a clamping handle 11 is provided at the other end.

[0028] The locking pin 1 is slidably connected to the sleeve 7 .

[0029] One end of the support push rod 2 is hinged to the hinge seat 6 , and the other end is slidably connected to the push rod groove 8 .

[0030] The stop pin 10 is slidably connected to the sleeve 7 , and the clamping handle 11 cooperates with the clamping ring 9 .

[0031] A limit block 12 is provided at one end of the support push rod 2 , and the limit block 12 is slidably connected to the push rod groove 8 .

[0032] A wedge block 13 is provided on one side of the fixing plate 4 .

[0033] There are two clamping rings 9.

[0034] The working process of the utility model is:

[0035] When unfolding, pull the clamp handle 11 to turn the locking pin 1 out of the clamp ring 9, push the locking pin 1 upward to the upper clamp ring 9, then rotate the locking pin 1, pull the clamp handle 11 to clamp the locking pin 1 in the upper clamp ring 9, and then rotate the movable platform 3 until the limit block 12 in the supporting push rod 2 is locked with the push rod groove 8, and the platform is unfolded;

[0036] When withdrawing, pull the ferrule handle 11 to turn the locking pin 1 out of the lower retaining ring 9, rotate the movable platform 3 to the withdrawn state, at which time the locking pin 1 automatically slides down, and then rotate the locking pin 1, pull the ferrule handle 11 to clamp the locking pin in the lower retaining ring 9, at which time the stop pin 10 in the locking pin 1 is just clamped with the wedge-shaped fast 13, and the withdrawal is completed.

[0037] Example 2

[0038] like Figure 1 , 2 As shown in , 4 and 7 , the movable platform 3 and the fixed plate 4 are connected by the hinge 5 to realize the flipping of the movable platform 3 .

[0039] like Figure 1 , 4As shown in Figures 5 and 6, the locking pin 1 is slidably connected to the sleeve 7 in the movable platform 3. When the platform is unfolded, the clamping handle 11 in the locking pin 1 is clamped with the clamping ring 9 in the movable platform 3, thereby realizing unlocking when the movable platform 3 is flipped; when the platform is withdrawn, the stop pin 10 in the locking pin 1 is clamped with the wedge block 13 in the fixed plate 4, and the clamping handle 11 in the locking pin 1 is clamped with the clamping ring 9 in the movable platform 3, thereby realizing reliable locking of the movable platform 3 during the driving of the special vehicle, thereby ensuring the driving safety of the vehicle. Figure 1 , 4 , 5, 6, and 7 as shown.

[0040] like Figure 1 , 3 As shown in FIGS. 4 and 6 , when the platform is unfolded, the limit block 12 in the supporting top rod 2 is locked with the top rod groove 8 in the movable platform 3 , thereby achieving the limit and reliable support of the movable platform 3 and ensuring the safe use of the movable platform 3 .

[0041] like Figure 1 , 8 As shown, it has the function of folding when the vehicle is driving and the function of unfolding when in use, which meets the needs of two working conditions: driving and operation of special vehicles.

[0042] To sum up, the utility model realizes the expansion and contraction of the movable platform, and solves the different needs of the special vehicle during the driving process and the use process; by adding a supporting top rod, the limiting and reliable support of the movable platform are realized, and the safe use of the movable platform is guaranteed; by adding a locking pin, the reliable locking of the movable platform during the driving of the special vehicle is solved, and the driving safety of the vehicle is ensured; the structure is ingenious, the operation is reliable, the cost is low, the installation is convenient, the structure is compact, simple and universal, and it is easy to promote and apply.
