DETAILED DESCRIPTION

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example 1

[0025] Reference Figures 1 to 4 , which is the first embodiment of the utility model, provides a semi-trailer with a liftable sidewall, comprising:

[0026] The supporting mechanism 100 includes a vehicle floor 101, and a side door 102 is provided on one side of the vehicle floor 101;

[0027] Furthermore, a lifting mechanism 300 is disposed on a side of the side door 102 opposite to the vehicle floor 101 , and a limiting mechanism 200 is disposed on one side of the lifting mechanism 300 .

[0028] Specifically, the lifting mechanism 300 includes a hollow guardrail 303, a lifting guardrail 306 is slidably installed inside the hollow guardrail 303, a second fixed block 304 is fixedly installed on one side of the hollow guardrail 303, a rotating shaft 301 is rotatably connected to one side of the second fixed block 304, and a worm 309 is fixedly sleeved on the outer surface of the rotating shaft 301.

[0029] The hollow guardrail 303 is fixedly installed on the top of the vehicle bottom plate 101 , and the side door 102 is hinged on one side of the hollow guardrail 303 .

[0030] Furthermore, the inner surface of the hollow guardrail 303 is rotatably connected to a screw rod 307 , the outer surface of the screw rod 307 is fixedly sleeved with a worm gear 308 , the interior of the lifting guardrail 306 is provided with a hole 302 , and a U-shaped plate 305 is fixedly installed on one side of the vehicle floor 101 .

[0031] Among them, the screw rod 307 is rotatably connected to the inside of the lifting guardrail 306 through a thread, and the other end of the screw rod 307 is rotatably connected to the top of the inner surface of the hollow guardrail 303, the worm wheel 308 is engaged with the worm 309, the screw rod 307 is located in the inner cavity of the hole 302, and the lifting guardrail 306 is slidably connected to the inside of the U-shaped plate 305.

[0032] When in use, the limiting mechanism 200 is controlled to drive the rotating shaft 301 to rotate, the rotating shaft 301 drives the worm 309 to rotate, the worm 309 drives the worm wheel 308 to rotate, the worm wheel 308 drives the screw rod 307 to rotate, and the screw rod 307 drives the hollow railing 303 to move upward in the hollow railing 303 through the thread. Since the screw rod 307 is composed of three groups and rotates synchronously, the lifting railing 306 can be smoothly raised. Under the action of the U-shaped plate 305, the lifting railing 306 is controlled to rise excessively, and the lifting railing 306 can be raised and moved to a position parallel to the highest point of the side door 102 and the vehicle floor 101.

[0033] In summary, through the action of the lifting mechanism 300, the sideboard can be raised. If there are goods with light weight and large volume, it is convenient to stabilize the goods inside the car and facilitate transportation. There is no need for the driver to get off the car to observe after a period of time, which improves the transportation efficiency of the goods. Under the action of the limiting mechanism 200, the reverse movement of the lifting sideboard 306 is limited, so the goods can be smoothly transported to the destination.

[0034] Example 2

[0035] Reference Figure 1 , 4 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a limiting mechanism 200 to ensure that the lifting railing 306 does not move downward during the transportation of goods.

[0036] Specifically, the limiting mechanism 200 includes a first fixed block 202 , a housing 201 is fixedly mounted on one side of the first fixed block 202 , and a turning handle 204 is rotatably connected inside the housing 201 .

[0037] Furthermore, a ratchet 203 is fixedly sleeved on the outer surface of the turning handle 204 , and a thorn 206 is fixedly sleeved on the outer surface of the limiting rod 207 fixedly connected to one side of the first fixing block 202 , and a spring 208 and a pull rod 205 are fixedly connected to the top of the thorn 206 .

[0038] Among them, the first fixed block 202 is fixedly installed on one side of the vehicle bottom plate 101, the rotating shaft 301 is rotatably connected to the inside of the first fixed block 202, the ratchet 203 is adapted to the thorn 206, the pull rod 205 is slidably connected to the inside of the shell 201, the other end of the spring 208 is fixedly connected to the shell 201, and the turning handle 204 is fixedly connected to the rotating shaft 301.

[0039] When in use, the handle 204 is manually turned, and the handle 204 drives the rotating shaft 301 to rotate, thereby driving the lifting mechanism 300 to operate, and the handle 204 drives the ratchet 203 to rotate. At this time, the thorn 206 is acted upon by the spring 208, so that the thorn 206 jumps on one side of the ratchet 203. After rotating to a suitable angle, the spring 208 pushes the thorn 206 to be stuck in the ratchet 203, thereby limiting the reverse rotation of the ratchet 203. To release the rotation of the ratchet 203, the pull rod 205 is manually pressed, and under the action of the pull rod 205, the thorn 206 is disengaged from the ratchet 203, and the handle 204 is reversely rotated.

[0040] In summary, under the action of the limiting mechanism 200, the raising and lowering of the lifting railing 306 can be controlled, and it can be ensured that the lifting railing 306 will not move downward during the transportation of goods, thereby ensuring the safety of the goods. At the same time, it can also reduce the number of times the driver gets off the vehicle to observe the goods, thereby improving transportation efficiency.

Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and ratio of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present utility model.
