[0041] Specifically, in the above specific embodiments, refer to Figure 3 , Figure 4 and Figure 8 , a pull rod 205 is fixedly arranged at one end of the fixed rod 202 which is arranged inside the connecting rod 201, and both ends of the pull rod 205 penetrate the connecting rod 201 and extend outside the connecting rod 201. When the pull rod 205 is pulled outward, the fixed rod 202 can be driven to move outward, and the fixed rod 202 can be disengaged from the corresponding fixed rod slot. At this time, the control mechanism 2 can move up and down in the slide slot 119, so that the connecting rope 105 can be pulled to move with it, and then the piston 103 in the air cylinder 102 can be pulled to move with it, and then the airbag 108 can be inflated or deflated through the air cylinder 102. When in use, the airbag 108 in the box 107 can be inflated first, and then fruits and vegetables are placed in the box 107. At this time, the airbag 108 in the box 107 can be used to buffer the fruits and vegetables; when not in use, the airbag 108 in the box 107 can be deflated.
[0042] Specifically, in the above specific embodiments, refer to Figure 3 A handle 206 is fixedly provided on one end of the connecting rod 201 exposed outside the support plate 101, so that the entire control mechanism 2 can be moved by the handle 206 to inflate and deflate the airbag 108, and the entire cart can be pushed by the handle 206.
[0043] Specifically, in the above specific embodiments, refer to Figure 1 and Figure 2 The four corners of the bottom of the support plate 101 are fixed with movable legs 117 to facilitate the movement of the cart.
[0044] Specifically, in the above specific embodiments, refer to Figure 2 A box cover 118 is provided on the top of the box body 107 to facilitate closing or opening the box body 107.
[0045] The working principle of a transport cart for loading provided by the utility model is as follows:
[0046] The airbags 108 in the box 107 of the main body 1 can be inflated and deflated by moving the control mechanism 2. When the control mechanism 2 is moved to the upper end of the main body 1, the multiple airbags 108 located in the box 107 of the main body 1 will be in an inflated state. When the control mechanism 2 is moved to the lower end of the main body 1, the multiple airbags 108 located in the box 107 of the main body 1 will be in a deflated state.
[0047] In the initial state, the control mechanism 2 is located at the lower end of the main body 1, and the airbag 108 in the box 107 of the main body 1 is in a deflated state (i.e., a deflated state); when the device is to be used, first, the blocking rod 112 is pulled outward to move the blocking rod 112 to the side away from the tube body 110, so that the inner cavity of the tube body 110 is in a conducting state, so that the internal pipelines of the air cylinder 102 and the plurality of airbags 108 are unobstructed, and then the pull rod 205 is moved outward to separate the fixing rod 202 on the pull rod 205 from the support plate 101, and the fixing rod 205 is moved outward to separate the fixing rod 202 from the support plate 101. After the piston 103 is separated from the support plate 101, the piston 103 in the gas cylinder 102 will move toward the first spring 104 side under the action of the first spring 104, and at the same time, the connecting rod 201 will be pulled to move toward the upper end of the support plate 101 through the connecting rope 105, so that the entire control mechanism 2 automatically moves to the upper end of the support plate 101. In the process of the piston 103 moving toward the first spring 104 side, the gas in the gas cylinder 102 will be passed into the tube body 110 through the air pipe 106, and then input into the air bag 108 through the tube body 110, so that the gas The airbag 108 is inflated and bulged. After the inflation of the airbag 108 is completed, the blocking rod 112 is first released. At this time, the blocking rod 112 will automatically block the inner cavity of the tube body 110 under the elastic force of the second spring 113 to prevent the air cylinder 102 from continuing to inflate the airbag 108. Then the pull rod 205 is released. At this time, the fixing rod 202 on the pull rod 205 will automatically snap into the fixing rod slot provided at the upper end of the support plate 101 under the elastic force of the third spring 204, so that the control mechanism 2 is fixed to the upper end of the support plate 101 and no longer moves. At this time, the control mechanism 2 can be pushed The handle 206 on the control mechanism 2 is used to push the transport cart to move to the unloading location of the fruits and vegetables to be transferred. When the transport cart arrives at the unloading location of the fruits and vegetables to be transferred, the box cover 118 is opened first, and then the fruits and vegetables are placed in the box body 107. At this time, the multiple gas-filled air bags 108 in the box body 107 can be used to cushion the placed fruits and vegetables. When the fruits and vegetables to be transferred are small in size, the multiple support cloths 116 of the box body 107 can be pulled to expand the support cloths 116 to form a partition layer, which is convenient for layered storage of fruits and vegetables.When the use is finished, first, by pulling the blocking rod 112 outward, the blocking rod 112 is moved to the side away from the tube body 110, so that the inner cavity of the tube body 110 is in a conducting state, so that the internal pipelines of the air cylinder 102 and the multiple air bags 108 are unblocked, and then the pull rod 205 is moved outward to separate the fixed rod 202 on the pull rod 205 from the support plate 101, and then the handle 206 is pressed downward to drive the entire control mechanism 2 to move to the lower end of the support plate 101 through the handle 206, and the fixed rod 202 in the control mechanism 2 is automatically moved under the elastic force of the third spring 204. The fixing rod is engaged in the fixing rod slot provided at the lower end of the support plate 101, so that the control mechanism 2 is fixed to the lower end of the support plate 101 and no longer moves. When the control mechanism 2 moves downward, the piston 103 in the air cylinder 102 is driven to move to the side away from the first spring 104 through the connecting rope 105. At this time, the gas inside the airbag 108 will flow back into the air cylinder 102, that is, the airbag 108 is in a deflated state at this time. After the airbag 108 is deflated, the blocking rod 112 is released to block the tube body 110 again, and the use of the transport cart can be terminated.
[0048] Finally, it should be noted that the above description is only an embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made using the contents of the present utility model specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present utility model.
