Abstract
Description
Technical Field
[0001] The present invention relates to the field of sidewalk trucks, and in particular to a cargo compartment sidewalk support structure. Background Art
[0002] A flatbed truck is a truck that uses a flatbed structure. The flatbed is usually made of steel, aluminum alloy, fiberglass, and other materials. Compared with other types of trucks, flatbed trucks have the following characteristics: by setting up a flatbed structure, flatbed trucks can effectively utilize the compartment space, increase cargo capacity, and reduce transportation costs; the flatbed of a flatbed truck can be opened and closed, making loading and unloading of goods more convenient and quick, improving transportation efficiency; the flatbed of a flatbed truck can be adjusted as needed to meet the transportation needs of goods of different shapes and sizes. Because of the above advantages, most users who purchase commercial flatbed trucks require the flatbed cargo compartment to be equipped with a flatbed function. For example, when selling goods on the roadside, the flatbed is usually required to have a certain load-bearing capacity to increase the bottom area of the cargo compartment when selling goods and to accommodate more goods. However, the existing flatbed flatbed mechanism often supports the flatbed, which is prone to shaking as the vehicle moves, resulting in weak and unstable load-bearing capacity. Therefore, it is necessary to provide a cargo compartment flatbed support structure with stable and strong load-bearing capacity. Summary of the Invention
[0003] The present invention aims to provide a cargo compartment sidewall support structure, so as to provide a cargo compartment sidewall support structure with stable load-bearing and strong load-bearing capacity.
[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a cargo compartment railing support structure, including a base part, a pin shaft and a bracket, the base part includes a bottom plate and two mounting rings fixed on the bottom plate, the two ends of the pin shaft are respectively clamped on a mounting ring, a rotating ring is fixed at one end of the bracket, the rotating ring is rotatably connected to the pin shaft and there is a gap between the top of the rotating ring and the mounting ring, a plurality of slots are opened on the bottom mounting ring, and a limit key that can be inserted into the slot is provided at the bottom of the mounting ring.
[0005] The beneficial effects of this solution are as follows: through the above-mentioned arrangement, when it is necessary to flatten the cargo compartment sideboard, the rotating ring fixedly connected to the bracket is rotated, lifted upward and rotated to insert a limit key into a slot. Under the action of gravity, the limit key is inserted into the slot and limits the horizontal rotation of the rotating ring and the bracket. At this time, the sideboard can be placed on the bracket. Through the pin shaft and the base, the bracket can stably support the sideboard, so that the flat sideboard has a certain supporting capacity and can be used to place and display goods; at the same time, by setting the limit key, even if the vehicle is moved for a short time, the bracket will not rotate due to vibration, which will cause the sideboard to collapse and cause cargo loss; when the cargo compartment sideboard does not need to be flattened, it can be lifted upward and the rotating ring can be rotated to insert the limit key into other slots for storage. During normal driving of the vehicle, the bracket will not pop out and rub other vehicles around, thereby ensuring driving safety.
[0006] The limit key and slot arrangement allow for flexible adjustment of the bracket and quick switching between various states. Furthermore, the locking design, once the limit key is inserted into the slot, effectively prevents the bracket and sideboard from shaking when placed horizontally, ensuring the stability of the sideboard placement and further improving safety and reliability during use. This arrangement not only allows the tailgate of the cargo compartment to be leveled, but also allows the sideboards on all three sides of the cargo compartment to be leveled. Furthermore, the device is simple to manufacture, low in cost, easy to use, has a strong load-bearing capacity, and is easily adjustable.
[0007] Preferably, as an improvement, the bracket is in the shape of a right triangle, including a connecting beam fixed to the rotating ring, a support beam supporting the railing, and an oblique support beam for oblique support, and reinforcing ribs are welded and fixed in the bracket.
[0008] The beneficial effect is: by fixing the connecting beam, supporting beam and diagonal beam in sequence, a solid right-angled triangle frame is formed, which can ensure that the bracket will not deform or shake when carrying railings and heavy objects. The bracket is in the shape of a right-angled triangle, which can ensure that the railings are laid flat. The welded reinforcement ribs make the bracket have higher structural strength and improve the bearing capacity of the bracket.
[0009] Preferably, as an improvement, a spring is further included, with both ends of the spring respectively abutting against the upper surface of the mounting ring and the rotating ring.
[0010] The beneficial effect is: when the rotating ring needs to be adjusted, it is necessary to first overcome the elastic force of the spring to remove the limit pin, and then align it with other slots to insert it. The limit key of the bracket is firmly stuck in the slot of the base through gravity and the elastic force of the spring, so that when the railing is flat or in other states, the limit pin can be more firmly inserted into the slot, avoiding accidental falling off during vibration or slight movement. Since the spring always applies downward pressure, the limit pin can be stably fixed after being inserted into the slot, and the bracket will not loosen or the railing will collapse due to vehicle vibration or cargo shaking, which significantly improves the safety of the entire system.
[0011] Preferably, as an improvement, a rubber sleeve is sleeved on the upper surface of the support beam.
[0012] The beneficial effects are: the upper surface of the support beam is in contact with the guardrail. By setting the rubber sleeve, on the one hand, it can cushion the impact force of the guardrail with the support beam every time it is lowered, thereby avoiding deformation of the guardrail during use; on the other hand, it effectively reduces the direct contact between the guardrail and the support beam, reduces the physical damage such as scratches and dents that may occur after long-term use, and keeps the surface of the guardrail and the support beam in good condition. At the same time, the rubber sleeve can increase the friction between the contact surface of the support beam and the guardrail. When the guardrail is placed on the bracket, the rubber sleeve can reduce the sliding of the guardrail, prevent the guardrail from shaking or sliding during the placement of goods or transportation, and further improve the stability of the guardrail after it is flattened.
[0013] Preferably, as an improvement, a gasket is sleeved on the end of the bottom of the pin shaft passing through the mounting ring, the outer diameter of the gasket is larger than the inner diameter of the mounting ring, and a retaining spring is provided on the other side of the limiting piece to engage with the pin shaft.
[0014] The beneficial effects are: the retaining spring is clamped with the pin shaft, which can effectively prevent the pin shaft from falling out of the mounting ring during rotation or vibration. A gasket is set between the retaining spring and the mounting ring to buffer the contact between the retaining spring and the rotating ring, avoiding the rotating ring from causing repeated friction between the retaining spring and the mounting ring on the pin shaft during movement, which may cause the pin shaft to fall off easily. The above arrangement not only improves the durability of the structure, but also enhances its safety.
[0015] Preferably, as an improvement, the number of the slots is three, the angle between adjacent slots is 90 degrees, two of which are distributed on both sides of the rotating ring, and the remaining slot is arranged on the side close to the bottom plate.
[0016] The beneficial effect is: through the above-mentioned setting, when the limit pin is inserted into the slot close to the side of the bottom plate, the bracket can support the railing vertically relative to the car body. Through the slot setting on the left and right sides, when storing the rotating ring, it can be selectively rotated to the left or right for storage, which is convenient for setting it on both sides of the car body and has strong applicability.

[0018] Figure 2 Schematic diagram of the split structure of an embodiment of the present invention. DETAILED DESCRIPTION
[0019] The following is further described in detail through specific implementation methods:
[0020] The reference numerals in the drawings of the specification include: pin 1, base plate 2, mounting ring 3, rotating ring 4, slot 5, limit key 6, connecting beam 7, support beam 8, diagonal support beam 9, reinforcing rib 10, spring 11, gasket 12, retaining ring 13, and rubber sleeve 14.
[0021] Example
[0022] The embodiment is basically as follows Figure 1-Figure 2 As shown, Figure 1 and Figure 2 The cargo compartment railing support structure shown includes a base part, a pin shaft 1 and a bracket. The base part includes a bottom plate 2 and two mounting rings 3 fixed on the bottom plate 2. The bottom plate 2 is welded and fixedly connected to the car body. Both ends of the pin shaft 1 are respectively clamped on a mounting ring 3. A rotating ring 4 is fixed at one end of the bracket. The rotating ring 4 is rotatably connected to the pin shaft 1 and there is a gap between the top of the rotating ring 4 and the mounting ring 3. A plurality of slots 5 are opened on the upper surface of the bottom mounting ring 3. In this embodiment, the number of slots 5 is three, and the angle between adjacent slots 5 is 90 degrees. Two of them are distributed on both sides of the rotating ring 4, and the remaining slot 5 is arranged on the side close to the bottom plate 2. A limit key 6 that can be inserted into the slot 5 is provided at the bottom of the mounting ring 3. It also includes a spring 11. The two ends of the spring 11 are respectively against the mounting ring 3 and the upper surface of the rotating ring 4. When adjusting the rotating ring 4, it is necessary to overcome the spring 11 first. The limit pin is taken out by the elastic force, and then inserted into the other slots 5. The limit key 6 of the bracket is firmly stuck in the slot 5 of the base through gravity and the elastic force of the spring 11, so that the limit pin can be more firmly inserted into the slot 5 when the railing is flat or in other states, avoiding accidental falling off during vibration or slight movement. Since the spring 11 always applies downward pressure, the limit pin can be stably fixed after being inserted into the slot 5, and the bracket will not loosen or the railing will collapse due to vehicle vibration or cargo shaking, which significantly improves the safety of the entire system; when the limit pin is inserted into the slot 5 near the side of the bottom plate 2, the bracket can support the railing vertically relative to the car body. Through the arrangement of the slots 5 on the left and right sides, it can be selectively rotated to the left or right for storage when storing the rotating ring 4, which is convenient for setting it on both sides of the car body and has strong applicability.
[0023] like Figure 1As shown, the bracket is in the shape of a right triangle, including a connecting beam 7 fixed to the rotating ring 4, a supporting beam 8 supporting the railing, and an oblique support beam 9 for oblique support, which are welded in sequence. The connecting beam is fixed to the rotating ring 4 by welding, and a reinforcing rib 10 is also welded and fixed in the bracket. By fixing the connecting beam 7, the supporting beam 8, and the oblique support beam 9 in sequence, a sturdy right triangle frame is formed, which can ensure that the bracket will not deform or shake when carrying the railing and heavy objects. The bracket is in the shape of a right triangle, which can ensure that the railing is level. The welded reinforcing rib 10 makes the bracket have higher structural strength and improves the bearing capacity of the bracket. The upper surface of the support beam 8 is also covered with a rubber sleeve 14, and there are two rubber sleeves 14. The upper surface of the support beam 8 is in contact with the guardrail. By setting the rubber sleeve 14, on the one hand, it can buffer the impact force of the guardrail with the support beam every time it is lowered, thereby avoiding deformation of the guardrail during use. On the other hand, it effectively reduces the direct contact between the guardrail and the support beam 8, reduces the physical damage such as scratches and dents that may occur after long-term use, and keeps the surface of the guardrail and the support beam 8 in good condition. At the same time, the rubber sleeve 14 can increase the friction between the contact surface of the support beam 8 and the guardrail. When the guardrail is placed on the bracket, the rubber sleeve 14 can reduce the sliding of the guardrail, prevent the guardrail from shaking or sliding during the placement of goods or transportation, and further improve the stability of the guardrail after it is flattened.
[0024] like Figure 1 The bottom of the pin shaft 1 shown passes through the bottom of the mounting ring 3 and is also sleeved with a gasket 12. The outer diameter of the gasket 12 is larger than the inner diameter of the mounting ring 3. The other side of the limit plate is also provided with a retaining spring 13 that is clamped and fixed to the end of the pin shaft 1. The retaining spring 13 is clamped with the pin shaft 1, which can effectively prevent the pin shaft 1 from falling out of the mounting ring 3 during rotation or vibration. A gasket 12 is arranged between the retaining spring 13 and the mounting ring 3 to buffer the contact between the retaining spring 13 and the rotating ring 4, so as to avoid the rotating ring 4 driving the retaining spring 13 on the pin shaft 1 and the mounting ring 3 to rub repeatedly during movement, causing the pin shaft 1 to fall off easily. The above arrangement not only improves the durability of the structure but also enhances its safety.
[0025] The specific implementation process is as follows:
[0026] When the load compartment railing is not required to be laid flat, the rotating ring 4 fixedly connected to the bracket is rotated, lifted up and rotated to insert the limit key 6 into a slot 5. Under the action of gravity and the action of the spring 11, the limit key 6 is inserted into the slot 5 and limits the horizontal rotation of the rotating ring 4 and the bracket. At this time, the railing can be placed on the bracket. Through the pin shaft 1 and the base part, the bracket can stably support the railing, so that the flat railing has a certain supporting capacity that can be used to place and display goods; at the same time, by setting the limit key 6, even if the vehicle is moved for a short time, the bracket will not rotate due to vibration, which will cause the railing to collapse and cause cargo loss; when the load compartment railing does not need to be laid flat, it can overcome the elastic force of the spring 11, lift it up and rotate the rotating ring 4 to insert the limit key 6 into other slots 5 for storage. Under the action of gravity and the action of the spring 11, the bracket will not pop out and rub other vehicles around during normal driving of the vehicle, thereby ensuring driving safety. The arrangement of the limit key 6 and the slot 5 allows for flexible adjustment of the bracket and rapid switching between various states. Furthermore, the locking design of the limit key 6 after insertion into the slot 5 effectively prevents the bracket and the side panel from shaking when placed horizontally, ensuring the stability of the side panel placement and further improving safety and reliability during use. The above arrangement not only enables the flattening of the cargo compartment tailgate, but also allows the flattening of the side panels on all three sides of the cargo compartment. Furthermore, the device is simple to manufacture, low in cost, easy to use, has a strong load-bearing capacity, and is easily adjustable.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
