Description

Technical Field

[0001] This utility model relates to the field of freight vehicle technology, specifically an adjustable fence for a semi-trailer. Background Technology

[0002] A semi-trailer is a type of trailer that is a heavy-duty transport vehicle connected to a semi-trailer unit via a towing pin. The basic materials for semi-trailers are steel, wood, and aluminum alloy. To meet the requirements of train operation and reduce train weight, semi-trailers tend to use more high-strength steel, lightweight alloys, and plastics. It is a trailer with its axle located behind the vehicle's center of gravity and equipped with a coupling device that transmits horizontal and vertical forces to the tractor unit.

[0003] Upon investigation, a utility model patent discloses an adjustable fence for a semi-trailer (publication number: CN219770024U), comprising: a base plate, with positioning grooves on both sides of the top of the base plate, and connecting rods rotatably mounted on both sides of the outer side of the base plate, with a total of four connecting rods, and a side plate rotatably mounted on one end of every two connecting rods, with a total of two side plates.

[0004] Although the aforementioned patent allows the sliding plate to slide at both ends of the side plate through the setting of connecting rods and side plates, making it easy to adjust according to the length of the semi-trailer's floor, and after adjustment, locking the knob allows the side plate to be installed with the floor, improving the practicality of the fence and avoiding the situation where the fence cannot be installed with semi-trailers of different lengths, the above solution requires manual adjustment, which is inefficient. Furthermore, the single-stage adjustment requires the installation of a longer guardrail, making it inconvenient for loading and unloading goods, as well as for disassembling and installing the fence.

[0005] Therefore, this utility model provides an adjustable fence for semi-trailers to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-4 As shown, this utility model provides an adjustable fence for a semi-trailer, including a mounting base 1. There are two mounting bases 1, which are connected by multiple first buffer mechanisms 2 and multiple second buffer mechanisms 3. An adjustment mechanism 4 is provided on the top of the mounting base 1.

[0027] The adjustment mechanism 4 includes a first slide 401 and a second slide 402. Both the first slide 401 and the second slide 402 are located on the top of the mounting base 1. The inner walls of the first slide 401 and the second slide 402 are slidably connected to a first slider 403 and a second slider 404, respectively. The top of the first slider 403 is fixedly connected to a first fence 405, and the top of the second slider 404 is fixedly connected to a second fence 406. Both sides of the mounting base 1 are provided with a drive mechanism 5.

[0028] The drive mechanism 5 includes two motors 501, which are fixedly connected to both sides of the mounting base 1. The output ends of the two motors 501 are connected to lead screws 502. The outer walls of the two lead screws 502 are threadedly connected to the inner walls of the first slider 403 and the second slider 404, respectively. By setting the drive mechanism 5, the fence can be quickly unfolded without manual adjustment, thereby improving the adjustment efficiency of the fence.

[0029] The top of the mounting base 1 is fixedly connected to a third fence 6. Both the interior of the third fence 6 and the interior of the first fence 405 are provided with telescopic grooves. The third fence 6 is movably connected to the first fence 405 through the telescopic grooves. The first fence 405 is movably connected to the second fence 406 through the telescopic grooves. By setting the first fence 405, the second fence 406 and the third fence 6, and by adjusting the multi-level telescopic extension of the fences, the space occupied by the fences can be reduced, thereby facilitating the unloading of goods.

[0030] The first buffer mechanism 2 includes two connectors 201. The two connectors 201 are fixedly connected to opposite ends of two fixed bases. The outer walls of the two connectors 201 are fitted with connecting rings 202. The outer walls of the two connecting rings 202 are connected by the same steel cable 203. By setting the first buffer mechanism 2, when one side of the fence is squeezed, the other side of the fence can be pulled, thereby ensuring the stability of the fence on the squeezed side and preventing the goods from crushing the fence and causing it to roll down.

[0031] The second buffer mechanism 3 includes a load-bearing plate 301. The load-bearing plate 301 is internally connected to two movable frames 302. The ends of the two movable frames 302 that are far apart are respectively fixedly connected to the opposite ends of the two mounting bases 1. The opposite ends of the two movable frames 302 are connected by the same high-strength spring 303. By setting the second buffer mechanism 3, when one side of the fence is squeezed, the fence on the other side can buffer it, which can reduce the direct force of the goods on the side fence, thereby reducing the damage caused by the side fence being squeezed by the goods.

[0032] The second fence 406 has a slot inside, and the two second fences 406 are inserted into the same baffle 7 through the slot. The top of the second fence 406 and the top of the baffle 7 are both provided with mounting holes. The second fence 406 is detachably connected to the mounting part 8 through the mounting holes. The mounting part 8 is detachably installed to the third fence 6 through the mounting holes. By setting the baffle 7, the cargo at the rear can be blocked.

[0033] Working principle:

[0034] When in use, to unfold the fence, first start the left motor 501. The motor 501 drives the lead screw 502 to rotate. Since the lead screw 502 and the first slider 403 are connected by a thread, the lead screw 502 can drive the first slider 403 to slide along the first slide groove 401, thereby moving the second fence 406 out from inside the first fence 405. Then start the right motor 501. The motor 501 drives the lead screw 502 to rotate. Since the lead screw 502 and the second slider 404 are connected by a thread, the lead screw 502 can drive the second slider 404 to slide along the second slide groove 402, thereby moving the third fence 6 out from inside the second fence 406, thus quickly unfolding and adjusting the entire fence.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
