[0026] Example one

[0027] A high-altitude vehicle stroke limiting device, see Figures 1-3 It includes a mounting plate 1, a stroke switch 2 and a limiting mechanism 3. The mounting plate 1 is formed by punching and bending a metal plate, one end of which is bent to form a guard 11 perpendicular to the main body of the mounting plate 1, and the other end is bent twice to form a U-shaped locking clamp 12. The mounting plate 1 has two sets of bolt holes 13 on both sides of the U-shaped slot of the locking clamp 12. The stroke switch 2 is installed vertically on the front of the mounting plate 1, close to the guard 11, and the front of the mounting plate 1 is provided with screw holes for mounting the stroke switch 2. The limiting mechanism 3 is arranged next to the stroke switch 2 and also installed on the front of the mounting plate 1. The limiting mechanism 3 is provided with a movable column 31, a fixed column 32, a bottom cover 33, a top cover 34, a spring 35 and a touch piece 36. The fixed column 32 is made of a round pipe or a square pipe, and is welded and fixed on the front of the mounting plate 1, beside the stroke switch 2. A limit slot 38 is formed at the top of the fixed column 32 on one side of the stroke switch 2. The bottom cover 33 and the top cover 34 have the same outer dimensions as the cross-sectional dimensions of the fixed column 32, and are correspondingly capped on the bottom and top of the fixed column 32 and welded and fixed with the fixed column 32. A circular hole with an outer diameter slightly larger than that of the movable column 31 is formed in the middle of the bottom cover 33 and the top cover 34, and the movable column 31 is movably arranged in the inner cavity of the fixed column 32, with both ends passing through the circular holes of the bottom cover 33 and the top cover 34. The movable column 31 is provided with a locking hole above the touch piece 36, and a nut 39 is welded and fixed at the locking hole. The movable column 31 and the fixed column 32 form a reset slot 37. The touch piece 36 is located directly above the stroke switch 2, one end of which is welded to the movable column 32 and located inside the fixed column 32, and the other end is located outside the fixed column 32, and the touch piece 36 is movably arranged in the limit slot 38. The initial length of the spring 35 is not less than the height of the fixed column, and the spring 35 is sleeved on the movable column 31 and located in the reset slot 37. The lower end of the spring 35 abuts against the bottom cover 33, and the upper end of the spring 35 abuts against the lower surface of the touch piece 36. The movable column 31 can drive the touch piece 36 to move a certain distance downward along the mounting plate 1 under the action of external downward force, and make the touch piece 36 contact and trigger the stroke switch 2.

[0028] The utility model discloses a locking device for high-altitude vehicle, which comprises a mounting plate, a locking bolt, a spring, a contact piece and a travel switch.

[0029] Example two

[0030] The difference between the present example and example one is that in the present example, the bottom cover 33 is designed on the mounting plate 1 alone or the bottom cover 33 is designed on the mounting plate 1 together with the top cover 34 (as shown in the figure), so that it is formed by stamping and bending the mounting plate 1 and is formed as an integral molding structure with the mounting plate 1. Figure 4
