Abstract
Description
Technical Field
[0001] The invention relates to a military folding carrier. Background Art
[0002] At present, a transport vehicle is generally a tool for transporting supplies. In the military, it can be used to transport military supplies. The existing transport vehicles generally have rolling wheels and a support plate. The bottom of the support plate is supported and rolled by the rolling wheels, and the support plate is used to load supplies. However, the existing transport vehicles generally have a fixed size, which is very inconvenient when the military carries the transport vehicles. In the military, when the external environment is complex and changeable, and the space requirements are relatively harsh, it is impossible to flexibly transport supplies in a small space because the existing transport vehicles cannot flexibly adjust their size. When encountering mountainous areas, the balance of the transport vehicle's movement cannot be guaranteed.

The two cross links 35 are rotatably connected. A sliding sleeve 37 is installed on the inner side of the intersection of the two cross links 35. The sliding sleeve 37 is inserted into a guide post 36. The lower end of the guide post 36 is fixed to the fixed base plate 1, and the upper end of the guide post 36 is connected to the side of the lifting plate 4. A clamping plate 34 is installed on the front and rear sides of the lifting plate 4, and the clamping plate 34 is provided with a sliding slot. The upper end of the cross link 35 is slidably engaged with the sliding slot of the clamping plate 34. In this way, the horizontal screw 32 of the lifting motor 3 is rotated, and the rotation of the horizontal screw 32 drives the horizontal movable sleeve 33 to move.

[0032] The rotating plates 11 at the front and rear ends of the fixed base plate 1 of the present invention can rotate, so that the balance plates 12 on the left and right sides of the fixed base plate 1 can be lifted and lowered left and right through the dampers 13, so that the balance plates 12 can drive the supporting rollers 2 to lift and lower left and right, and at the same time keep the foldable panel 9 level, so that the level of the foldable panel 9 can still be ensured when encountering an inclined conveying ground, thereby improving the stability of conveying; the outer side of the upper end of the balance plate 12 of the present invention is rotatably connected to the supporting roller 2 through the lifting component 121, so that the height of the balance plate 12 can be further lowered, so that the height of the foldable panel 9 can be lowered, so that the foldable panel 9 can be adjusted downward to the inner side and lower part of the supporting roller 2, so as to achieve retraction and facilitate carrying and transportation.
[0033] The foldable panel 9 is composed of multiple plates connected in sequence and rotated. When folded, the foldable panel 9 folds similarly to a folding fan; the telescopic hinge rod 8 is similar to the hinge structure used on a horizontally moving electric telescopic door; the present invention uses a nanobattery as a driving power source, and a speed adjustment handle, a control panel, a handbrake and other control mechanisms can be set on the hand steering rod 101, and the electrical components of the entire structure are powered by the nanobattery.
