DETAILED DESCRIPTION

[0021] See also Figure 1-4 A manual hydraulic platform vehicle with high stability includes a hydraulic vehicle 1. A limiting mechanism 2 is arranged above the hydraulic vehicle 1. The limiting mechanism 2 includes two groups of rectangular columns 202 and a platform plate 201. Two groups of universal wheels 3 are fixedly connected to the bottom surface of the hydraulic vehicle 1. A pushing handle 4 is fixedly connected to the upper surface of the hydraulic vehicle 1. By providing the universal wheels 3 and the pushing handle 4, the device can be pushed to move by the pushing handle 4, and the universal wheels 3 can reduce the resistance encountered by the device when it moves.

[0022] An extension plate 203 is fixedly connected to a side surface of each group of rectangular columns 202 that is away from each other, and the bottom surface of each extension plate 203 is in contact with the upper surface of the platform plate 201, wherein the inner walls of the two groups of extension plates 203 are fixedly connected to two groups of first bearings 208, and the inner ring of each group of first bearings 208 is fixedly connected to two first rotating shafts 209, and the ends of each group of first rotating shafts 209 that are close to each other are commonly fixedly connected to a threaded shaft 207, wherein two rotating handles 5 are arranged in front of the two first rotating shafts 209, and the end of each rotating handle 5 close to the threaded shaft 207 is fixedly connected to the end of the first rotating shaft 209 away from the threaded shaft 207, and by providing the rotating handle 5, the first rotating shaft 209 can be driven to rotate by the rotating handle 5, thereby facilitating the application of rotational power to it.

[0023] The outer surface of each threaded shaft 207 is threadedly connected to the limiting plate 205, and the side of the two limiting plates 205 that are close to each other are fixedly connected with a protective pad 206. A square groove 6 is provided on the side of each rectangular column 202 away from the threaded shaft 207, and a rectangular groove 8 is provided on the bottom surface of each rectangular column 202. By providing the square groove 6 and the rectangular groove 8, the limiting device can be used to indirectly limit the rectangular column 202, which has a better auxiliary effect.

[0024] The other two extension plates 203 are fixedly connected to two limit columns 204 on one side close to each other, and the inner wall of the platform plate 201 is fixedly connected to two groups of second bearings 10, and the inner ring of each group of second bearings 10 is fixedly connected to two second rotating shafts 9. By providing the second bearings 10 and the second rotating shafts 9, the second rotating shafts 9 can rotate inside the second bearings 10, thereby providing a relatively stable fixation for the second rotating shafts 9.

[0025] The outer surface of each limit column 204 is slidably connected to the inside of the limit plate 205, the bottom end of each second rotating shaft 9 is fixedly connected to the rotating plate 11, the top of each rotating plate 11 is fixedly connected to the limit block 7, and the bottom surface of each limit block 7 is in contact with the inner bottom wall of the rectangular column 202. By providing the rotating plate 11 and the limit block 7, the second rotating shaft 9 can be driven to rotate by the rotating plate 11, and the limit block 7 can limit the rectangular column 202.

[0026] The working principle of the utility model is as follows: when in use, it is only necessary to move the pushing device by pushing the handle 4 to move the device to a suitable position, and then the items to be transported can be placed on the surface of the platform plate 201. If the existence of the limiting mechanism 2 will cause difficulties in placing the items, the two sets of rotating plates 11 can be rotated, and the second rotating shaft 9 fixed on the upper surface of the rotating plate 11 will also rotate, thereby rotating the limiting block 7, thereby releasing the fixation of the rectangular column 202, and then the entire limiting mechanism 2 can be removed. When the items to be transported are placed on the surface of the platform plate 201, the two sets of rectangular columns 202 can be inserted into the interior of the platform plate 201 again. When extending into the interior of the platform plate 201, it is necessary to ensure that The limit block 7 can pass through the rectangular groove 8 opened on the bottom surface of the rectangular column 202 and enter the inside of the square groove 6. Then, the rotating plate 11 can be rotated again to limit the two groups of rectangular columns 202. When the rectangular columns 202 are fixed, the rotating handle 5 can be rotated. The rotation of the rotating handle 5 will drive the first rotating shaft 209 and the threaded shaft 207 to rotate. With the threaded connection relationship between the threaded shaft 207 and the limit plate 205, the limit plate 205 can be pushed to move. Note that the two rotating handles 5 rotate in different directions and need to be rotated in opposite directions, so that the items to be transported can be fixed from the front and back, effectively avoiding the problem of low stability of the items transported on the surface of the device due to the lack of the limiting mechanism 2 when the device is in use.
