Description

Technical Field

[0001] The utility model belongs to the technical field of semi-trailers, and in particular relates to a leakproof semi-trailer compartment. Background Art

[0002] A semi-trailer is a type of trailer. It is a heavy-duty transport vehicle connected to the front of the semi-trailer by a towing pin. It has no power itself and shares the load with the main vehicle and is towed by the main vehicle. The semi-trailer's compartment has a floor, side panels and doors. There are certain gaps between the side panels and the doors and the floor, which can easily cause items in the compartment to fall out of the gap when the vehicle is bumpy; especially the door can be rotated open. When the vehicle encounters a bumpy road or starts or stops suddenly, the goods in the vehicle will squeeze the door due to inertia, causing the gap between the door and the floor to become larger, causing the goods in the vehicle to fall out. In severe cases, it may even cause the door to deform, resulting in irreparable holes between the door and the floor.

[0003] Therefore, a leakproof semi-trailer compartment is needed that can cover the gap in the compartment to prevent the cargo from leaking out. Utility Model Content

[0004] In view of the problem of cargo falling and losing in the semi-trailer compartment in the prior art, the utility model provides a leak-proof semi-trailer compartment, which can cover the gaps between the bottom plate, the side compartment plate and the compartment door by setting a leak-proof cloth, and adopts a structure coordinated with a T-shaped limit groove and a T-shaped limit block to prevent the leak-proof cloth from shifting and folding and losing its function. It is also convenient to install and simple to operate, so that the driver alone can quickly install the leak-proof cloth.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] The leakproof semi-trailer compartment is characterized by: comprising

[0007] The carriage comprises a bottom plate, side panels and a door, wherein the side panels are fixedly connected to both sides of the bottom plate; the door is hinged to the bottom plate at the bottom, and the two sides of the door are detachably connected to the two side panels;

[0008] There are two horizontal leak-proof structures, which are respectively arranged at the connection between the two side compartment plates and the bottom plate. The horizontal leak-proof structure includes an upper limit plate, a lower limit plate and a first leak-proof cloth. The upper limit plate is fixed to the side compartment plate, and a T-shaped limit groove is opened on the bottom surface. A T-shaped limit groove is opened on the side of the side compartment plate close to the lower limit plate. T-shaped limit blocks are fixedly arranged on both sides of the first leak-proof cloth, and are limitedly clamped with the T-shaped limit grooves of the upper limit plate and the lower limit plate;

[0009] There are two vertical leak-proof structures, which are arranged at the connection between the two side compartment plates and the compartment door. Each vertical leak-proof structure includes a fixed limiting end arranged on the side compartment plate, a movable limiting end arranged on the compartment door and a second leak-proof cloth. The fixed limiting end and the movable limiting end are both provided with T-shaped limiting grooves, and T-shaped limiting blocks cooperating with the two T-shaped limiting grooves are arranged on both sides of the second leak-proof cloth.

[0010] The compartment door is hinged on the base plate and rotates around the rear end of the base plate, so when the cargo squeezes the compartment door, the upper position of the compartment door is more easily separated from the side compartment plate. The first leak-proof cloth of the horizontal leak-proof structure is inserted into the T-shaped limit block into the T-shaped limit groove, and the first leak-proof cloth is pulled to completely cover the bottom gap between the side compartment plate and the base plate; the vertical leak-proof structure inserts the T-shaped limit block into the T-shaped limit groove of the side compartment plate and the compartment door, so that the second leak-proof cloth blocks the vertical gap between the side compartment plate and the compartment door. When the road conditions are rough or the cargo squeezes the compartment door due to other factors, the compartment door is squeezed and the gap becomes larger, and the second leak-proof cloth plays a role in blocking and preventing leakage.

[0011] Preferably, the width of the first anti-leakage cloth is greater than the distance between the upper limit plate and the lower limit plate when the side compartment plate is horizontal with the bottom plate, and the width of the second anti-leakage cloth is greater than the distance between the fixed limit end and the movable limit end when the side compartment plate is horizontal with the compartment door.

[0012] The tension force on the first leak-proof cloth and the second leak-proof cloth is reduced, so that the first leak-proof cloth and the second leak-proof cloth are laid on the bottom plate to avoid bearing the weight of the goods and extend the service life.

[0013] Preferably, the first leak-proof cloth and the second leak-proof cloth are both made of nylon.

[0014] Nylon material has high wear resistance and is not easily damaged, reducing the number of replacements.

[0015] Preferably, the inner surface of the door is further provided with an anti-collision layer, the anti-collision layer comprises a hard layer and a buffer layer, the buffer layer is fixedly bonded to the inner surface of the door, and the hard layer is bonded to the buffer layer.

[0016] The anti-collision layer is used to protect the compartment door when transporting heavy items, preventing the cargo from hitting the compartment door and causing deformation of the compartment door during emergency stop or start.

[0017] Preferably, the outer surface of the anti-collision layer is a curved structure with a high middle and low surroundings.

[0018] When transporting large cargo, the closer the door is to the middle, the more vulnerable it is to impact, so the anti-collision layer is designed with a thicker structure in the middle to accommodate the cargo, thereby protecting the door and cargo.

[0019] Preferably, the hard layer is hard metal, and the buffer layer is elastic rubber.

[0020] The buffer layer is elastic rubber. When the hard layer is squeezed by the cargo, it can be compressed to absorb a certain amount of force to protect the compartment door and cargo.

[0021] Preferably, a spring is further provided in the buffer layer, one end of the spring is in contact with the compartment door, and the other end of the spring is in contact with the hard layer.

[0022] Preferably, an L-shaped limit rod is hinged on the compartment door, and an L-shaped limit seat is welded on the side compartment panel. The L-shaped limit rod includes a rotating part and a limit part. The limit part is snap-fitted with the L-shaped limit seat. An elastic buffer sleeve is sleeved outside the limit part. The elastic buffer sleeve includes an outer layer and an inner layer. The inner layer is sleeved outside the limit part, and the inner layer and the outer layer are connected by a spring.

[0023] The L-shaped limit rod and the L-shaped limit seat do not play the role of fixing the connection between the side panel and the door. The side panel and the door are connected by hinged, clamped or other methods using existing technology. The L-shaped limit rod and the L-shaped limit seat in this scheme play a double protection role. When the connection between the side panel and the door is squeezed and hit by the cargo, resulting in the connection effect being deteriorated or failing, it can prevent the door and the side panel from further separating and causing the gap to become larger. Specifically, the elastic buffer sleeve of the limiting part is clamped with the L-shaped limit seat to prevent the door from further deformation, and use the spring force to push the L-shaped limit rod toward the front of the vehicle, and then pull the door hinged to the L-shaped limit rod, thereby helping the door to reset.

[0024] The beneficial effects of the utility model are as follows: the first leak-proof cloth and the second leak-proof cloth are provided to block the gaps between the side compartment plate and the bottom plate, and between the side compartment plate and the compartment door, thereby preventing small cargo from leaking out of the gaps; especially when the vehicle encounters a rough road section or makes an emergency stop or start during driving, causing the cargo to squeeze the compartment door due to inertia, the utility model plays the role of connecting the compartment door and the side compartment plate, blocking a larger gap between the compartment door and the side compartment plate, thereby preventing the cargo from being stuck in the gap and being damaged or falling off.
