DETAILED DESCRIPTION
[0021] The following is combined with Figure 1-7 The utility model is further described as follows:
[0022] A folding trolley comprises a side piece a1 and a side piece b2 arranged opposite to each other, a middle layer mesh 7 and a binding belt 8 are arranged between the side piece a1 and the side piece b2, one end of the middle layer mesh 7 is rotatably connected to the side piece b2, the other end of the middle layer mesh 7 is detachably connected to the side piece a1, the two ends of the binding belt 8 are detachably connected to the side piece a1 and the side piece b2, one end of a mesh chassis 6 is rotatably connected to the bottom of the side piece a1, the other end of the mesh chassis 6 is detachably connected to the bottom of the side piece b2, a folding mechanism 3 is arranged at the bottom of both sides of the mesh chassis 6, and the two ends of the folding mechanism 3 are respectively connected to the side piece a1 and the side piece b2. A connecting ring a6.1 is arranged at one end of the mesh chassis 6, the connecting ring a6.1 is sleeved on the horizontal wire at the bottom of the side piece a1, the connecting ring a6.1 is rotatably connected to the horizontal wire, and a hook a6.3 is arranged at the other end of the mesh chassis 6, and the hook a6.3 is detachably connected to the horizontal wire at the bottom of the side piece b2. A slidable sliding lock sleeve a5.1 is sleeved on the longitudinal wire in the middle of the side panel a1. When the mesh chassis 6 is flipped over and pressed against the surface of the side panel a1, the sliding lock sleeve a5.1 can slide and sleeve onto the outer periphery of the pin a6.2 at the end of the mesh chassis 6, thereby locking the position of the flipped mesh chassis 6.
[0023] The folding mechanism 3 includes a U-shaped plate a3.4 and a U-shaped plate b3.6 which are rotatably connected. The U-shaped plate a3.4 is rotatably connected to the side piece a1, and the U-shaped plate b3.6 is rotatably connected to the side piece b2. The outer sides of the side tubes of the side pieces a1 and b2 are respectively welded with a fixed plate a3.1 and a fixed plate b3.2. The U-shaped plate a3.4 is welded with a connecting plate 3.8 at the end. The fixed plate a3.1 is rotatably connected to the connecting plate 3.8 through a bolt assembly a3.3, the fixed plate b3.2 is rotatably connected to the U-shaped plate b3.6 through a bolt assembly b3.5, and the U-shaped plate a3.4 is rotatably connected to the U-shaped plate b3.6 through a bolt assembly c3.7. The bottoms of the fixed plates a3.1 and b3.2 are both provided with universal rollers 4 to facilitate the movement and steering of the trolley.
[0024] A slidable sliding lock sleeve b5.2 is sleeved on the longitudinal wire on the upper part of the side panel b2. When the middle mesh 7 is flipped over and pressed against the surface of the side panel b2, the sliding lock sleeve b5.2 can slide and sleeve onto the outer periphery of the pin b at the end of the middle mesh 7, thereby locking the position of the flipped middle mesh 7.
[0025] When the trolley needs to be folded, the strap 8 must be removed first. One end of the strap 8 is tied to the side piece, and the other end is hung on the other side piece through a hook. When removing the strap 8, just remove the hooking end of the strap 8 and the side piece, then hang the hook on it to the side piece on the tied side, and place the strap 8 on the outside of the side piece. Slide the sliding lock sleeve a5.1 and the sliding lock sleeve b5.2 upward, and then rotate the mesh chassis 6 90° counterclockwise as shown in FIG. Figure 1 and Figure 2As shown, the middle layer mesh 7 is rotated 90° clockwise, and then the sliding lock sleeve a5.1 and the sliding lock sleeve b5.2 are put down, the bottom end of the sliding lock sleeve a5.1 is sleeved on the end of the mesh bottom plate 6, and the sliding lock sleeve b5.2 is sleeved on the end of the middle layer mesh 7, so as to achieve the locking of the position of the mesh bottom plate 6 and the middle layer mesh 7 after the flip. At this time, the movement of the two side pieces is not restricted, and when any side piece is pushed, the two U-shaped plates on both sides will be folded inward at the same time with the bolt assembly as the rotation axis. At this time, the mechanism is in a fully folded state, and in the fully folded state, the U-shaped plate and the side piece are in a parallel state.
[0026] When the trolley needs to be opened, just pull the side plate, and the U-shaped plates on both sides will rotate with the bolt assembly as the axis, so as to open the side plates. When the two side plates are fully opened, the U-shaped plate a3.4 and the U-shaped plate b3.6 are located on the same straight line. Figure 4 As shown, the sliding lock sleeve a5.1 and the sliding lock sleeve b5.2 are slid upward, the mesh bottom plate 6 is rotated 90° clockwise, the middle mesh 7 is rotated 90° counterclockwise, the hook a6.3 at the end of the mesh bottom plate 6 is hooked to the side piece b2, the hook b at the end of the middle mesh 7 is hooked to the side piece a1, and then the end of the strap 8 with the hook is hooked to the side piece on the opposite side to form a stable state, as shown in FIG. Figure 1 As shown, the trolley is in a fully open state at this time.
[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
