Description

Technical Field

[0001] This utility model belongs to the field of cargo truck anti-slip technology, and particularly relates to a cargo truck that prevents goods from slipping off. Background Technology

[0002] In the logistics and warehousing sector, warehouse trucks, as crucial handling tools, directly impact logistics efficiency with their safety and ease of operation. However, existing warehouse trucks typically have fixed or plug-in fencing installed around their chassis to prevent cargo from slipping. Fixed fencing requires operators to cross over it during loading and unloading, significantly increasing the height at which goods are handled. This not only consumes considerable physical strength but also increases the risk of safety hazards due to improper handling posture. While plug-in fencing avoids the height issue, its disassembly and assembly require frequent manual operations, which are cumbersome and time-consuming. Especially in scenarios involving bulk loading and unloading, repeated disassembly and assembly of fencing greatly reduces operational efficiency and can easily lead to lost or damaged parts, increasing maintenance costs.

[0003] Therefore, it is essential to invent a cargo truck that prevents goods from slipping off. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cargo truck for preventing cargo from slipping, including a cargo truck chassis, casters, support plates, retractable enclosures, mounting brackets, horizontal shafts, and a push frame. The four corners of the cargo truck chassis are fixedly installed with casters, and two support plates are symmetrically fixedly installed at the upper end. The lower ends of the two support plates are rotatably installed with retractable enclosures, which are connected to the mounting brackets at the other end of the cargo truck chassis. Several horizontal shafts are fixedly installed between the two support plates, and the outer side of the upper end is fixedly connected to one end of the push frame.

[0005] Preferably, rectangular support plates are fixedly installed at the upper two corners of the rear end of the cargo truck chassis, and a bracket is fixedly installed at the middle of the front end of the cargo truck chassis. Several horizontal axes are equidistantly arranged between the two support plates along the vertical line.

[0006] Preferably, the retractable enclosure rotatably mounted on the lower ends of the two supporting uprights includes a supporting outer frame, enclosure uprights, tongues, retractable arms, and a pressing shaft. At least three supporting outer frames are provided, and a plurality of enclosure uprights are evenly distributed and installed on the inner sides of the three supporting outer frames. A tongue capable of inserting into the card seat is fixedly installed in the middle of the lowermost supporting outer frame. The two ends of the lowermost supporting outer frame are respectively fixedly connected to one end of the retractable arm rotatably mounted on the lower end of each supporting upright, and a pressing shaft is fixedly installed between the other ends of the two retractable arms.

[0007] Preferably, the cross-section of the support outer frame is a "U" - shaped structure. The tongue fixed in the middle of the front end of the lowermost support outer frame is a rectangular structure, and the socket through which the tongue can be inserted is provided through the socket.

[0008] Preferably, several of the enclosure vertical plates fixedly installed inside the support outer frame do not interfere with the two support vertical plates, and each enclosure vertical plate is fixedly installed inside the support outer frame in a vertical manner.

[0009] Preferably, the outer side of the rear end of the lowermost support outer frame is fixedly connected to the inner side of the lower end of one end of the retractable arm. A pressing shaft is fixedly installed between the upper ends of the two retractable arms. The retractable arm is a "Z" - shaped structure, and the upper end of the retractable arm extends outwards and does not interfere with the support vertical plate and the rear end of the cargo truck chassis.

[0010] Compared with the prior art, the utility model has the following beneficial effects: [[ID=<1000023>

[0011] In the utility model, the operator only needs to step on the pressing shaft of the retractable enclosure with the foot, which can drive the whole retractable enclosure to rotate upwards around the lower end of the support vertical plate, without manual disassembly of the enclosure, completely liberating both hands. When loading and unloading goods, the enclosure is quickly retracted, and the height of goods handling is greatly reduced, reducing physical consumption. After loading and unloading, release the pressing shaft, and the enclosure automatically and slowly resets under its own gravity, and the tongue is accurately inserted into the socket for locking. The whole process does not require complex operations, significantly improving the loading and unloading efficiency and saving operation time.

[0012] When the retractable enclosure of the utility model rotates upwards and retracts, it does not affect the loading and unloading of goods. After resetting, the tight protection system composed of multiple support outer frames and enclosure vertical plates can effectively prevent the goods from slipping. The tight cooperation between the tongue and the socket provides a stable locking effect for the enclosure, ensuring that the enclosure will not accidentally open even when the cargo truck is driving under complex working conditions such as bumpy roads and turning, comprehensively protecting the safety of goods transportation.

[0013] The design of driving the enclosure to retract and extend by foot - stepping in the utility model conforms to the ergonomic principle, reducing the labor intensity of the operator, and is especially suitable for long - time and high - frequency loading and unloading operation scenarios. The retractable enclosure has a simple and compact structure, and the "Z" - shaped design of the retractable arm avoids interference with other components and reduces wear.

[0021] As attached Figure 1 To be continued Figure 3 As shown:

[0022] This utility model provides a cargo truck for preventing cargo from slipping, including a cargo truck chassis 1, casters 2, support plates 3, retractable enclosures 4, mounting seats 5, horizontal shafts 6, and a push frame 7. Casters 2 are fixedly installed at the four lower corners of the cargo truck chassis 1, and two support plates 3 are symmetrically fixedly installed at the upper end. Retractable enclosures 4 are rotatably installed at the lower ends of the two support plates 3, and the retractable enclosures 4 are connected to the mounting seats 5 at the other end of the cargo truck chassis 1. Several horizontal shafts 6 are fixedly installed between the two support plates 3, and the outer side of the upper end is fixedly connected to one end of the push frame 7.

[0023] Furthermore, the cargo truck chassis 1 is integrally stamped from high-strength steel plate, with an electrophoretic anti-rust treatment on the surface to ensure load-bearing capacity and durability. Rectangular support plates 3, made of stainless steel, are vertically fixed to the upper two corners of the rear end of the cargo truck chassis 1 using high-strength bolts. A fixing bracket 5 is welded to the center of the front end of the cargo truck chassis 1; the bracket 5 is injection molded from engineering plastic and has embedded metal reinforcing ribs to enhance structural strength. Multiple horizontal shafts 6, made of carbon steel round tubes, are welded equidistantly along vertical lines between the two support plates 3. The support plates 3 and the horizontal shafts 6 form the rear enclosure structure of the cargo truck chassis 1, and together with the retractable enclosure 4, form an all-around enclosure structure.

[0024] Furthermore, the retractable enclosure 4 consists of a supporting outer frame 41, enclosure uprights 42, tongues 43, retractable arms 44, and a lower pressure shaft 45. At least three supporting outer frames 41 are provided, made of extruded aluminum alloy profiles. The enclosure uprights 42 are evenly fixed to the inner side of each supporting outer frame 41 using countersunk screws, and the surface of the enclosure uprights 42 is textured for anti-slip properties. At the center of the lowest supporting outer frame 41, a rectangular tongue 43 is fixed using a mortise and tenon joint. The tongue 43 is made of hard nylon with rounded ends for precise insertion into the slot of the card holder 5. Both ends of the lowest supporting outer frame 41 are bolted to one end of the retractable arm 44 at the lower end of the supporting upright 3. Each retractable arm 44 is rotatably mounted on the lower end of its corresponding supporting upright 3, ensuring flexible rotation. The other ends of two retractable arms 44 are welded together to a lower pressure shaft 45, which is a rubber-coated carbon steel shaft, improving walking comfort and anti-slip properties.

[0025] Furthermore, the "U"-shaped cross-section design of the supporting outer frame 41 ensures that the fence uprights 42 form a regular protective surface after installation, and effectively prevents the goods from sliding laterally. The fit between the tongue 43 at the front end of the lowest supporting outer frame 41 and the card holder 5 is precisely designed. The inner wall of the card holder 5 has a guide slope to ensure that the tongue 43 can be quickly and accurately inserted and locked when the fence is reset, forming a stable anti-detachment structure.

[0026] Furthermore, the fencing uprights 42 on the inner side of the supporting outer frame 41 are vertically fixed and installed. The installation spacing is optimized to ensure effective blocking of goods while avoiding increased cost and weight due to excessive spacing. A gap is reserved between the fencing uprights 42 and the supporting uprights 3 to ensure no interference during the opening and closing of the fencing. At the same time, rubber buffer strips are installed at the gap to reduce collision noise and wear.

[0027] Furthermore, the retractable arm 44 adopts a "Z"-shaped structure, made of cold-rolled steel plate with a wear-resistant coating. Its lower inner end is bolted to the outer rear end of the lowest support frame 41, while its upper end extends outwards and is reinforced with ribs to ensure stable torque transmission when the pressure shaft 45 is stepped on, thus rotating the entire enclosure. The installation angle and stroke of the retractable arm 44 have been simulated to ensure that the stepping height of the pressure shaft 45 conforms to ergonomics, and that the entire retraction and extension process is smooth and unobstructed, without interfering with the support uprights 3 or the cargo truck chassis 1.

[0028] The working principle is as follows: First, when loading and unloading goods are required, one operator steps on the lower pressure shaft 45 with their foot. The retractable arm 44, which is fixedly connected to the lower pressure shaft 45 and rotatably mounted on the lower end of the support plate 3, rotates upward around the lower end of the support plate 3 under the action of the stepping force. This causes the lowermost support frame 41 and the entire retractable enclosure 4 to rotate upward around the lower end of the support plate 3, thereby creating loading and unloading space. The other operator then performs the loading and unloading. After loading and unloading are completed, the stepping force on the lower pressure shaft 45 is slowly released. Under its own gravity, the retractable enclosure 4 rotates downwards and resets along its original rotation trajectory. At this time, the tongue 43 in the middle of the lowest supporting outer frame 41 aligns with the card seat 5 at the front end of the cargo truck chassis 1. Since the inner wall of the card seat 5 has a guide slope, the tongue 43 can be quickly and accurately inserted into the card seat 5 to form a stable locking state, fixing the retractable enclosure 4. Together with the rear enclosure structure composed of the supporting upright plate 3 and the horizontal axis 6, it forms an all-round enclosure, effectively preventing goods from slipping during transportation.

[0029] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
