Abstract
Description
Technical Field
[0001] The invention relates to the field of railroad cars, and in particular to a cargo compartment railroad support structure. Background Art
[0002] A flatbed truck is a truck with a flatbed structure, and 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, and 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 truck cargo compartment to be equipped with a flatbed function, such as when selling goods on the roadside, and usually require a certain load-bearing capacity after the flatbed is laid, so as to increase the bottom area of the cargo compartment when selling goods and place more goods. However, the flatbed supported by the existing flatbed mechanism is often prone to shaking as the vehicle moves, resulting in weak load-bearing capacity and unstable load-bearing. Therefore, it is necessary to provide a cargo compartment flatbed support structure with stable load-bearing capacity and strong load-bearing capacity. Summary of the invention
[0003] The present invention aims to provide a cargo compartment railing support structure, so as to provide a cargo compartment railing 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 scheme: 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, both 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 mounting ring at the bottom, 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 railing, the rotating ring fixedly connected to the bracket is rotated, lifted upward and the rotating ring is 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 railing can be placed on the bracket, and the bracket can stably support the railing through the pin shaft and the base, so that the flat railing 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 railing to collapse and cause cargo loss; when the cargo compartment railing 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 setting of the limit key and the card slot makes the bracket flexible to adjust and can quickly switch between multiple states. At the same time, the locking design after the limit key is inserted into the card slot effectively prevents the bracket and the railing from shaking when placed horizontally, ensuring the stability of the railing placement, and further improving the safety and reliability during use. The above setting can not only realize the flattening function of the tailgate of the cargo compartment, but also make the railings on the three sides of the cargo compartment flat. The device is simple to make, low cost, easy to use, strong load-bearing capacity, and convenient to adjust.
[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 supporting beam supporting the railing, and an oblique supporting beam for oblique support, which are fixed in sequence, and reinforcing ribs are also welded and fixed in the bracket.
[0008] The beneficial effects are: by fixing the connecting beam, the supporting beam and the diagonal beam in sequence to form a solid right-angled triangle frame, it can be ensured that the bracket will not deform or shake when carrying the guardrail and heavy objects. The bracket is in the shape of a right-angled triangle, which can ensure that the guardrail is laid flat. The welded reinforcement ribs make the bracket have higher structural strength and improve the bearing capacity of the bracket. The bracket in the present technical solution is detachable. By setting it in the shape of a right-angled triangle, it can be removed to form an inclined support on one side of the road steps. Sometimes the road steps are high and it is difficult for wheels to drive directly up. By disassembling multiple brackets and inverting them on the steps, it can be used to assist vehicles in driving up the steps.
[0009] Preferably, as an improvement, it further comprises a spring, and two ends of the spring respectively abut 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 take out 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 to avoid 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 not 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 as follows: the upper surface of the support beam is in contact with the railing. By setting the rubber sleeve, on the one hand, it can buffer the impact force of the railing with the support beam every time the railing is lowered, thereby avoiding deformation of the railing during use; on the other hand, it effectively reduces the direct contact between the railing 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 railing 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 railing. When the railing is placed on the bracket, the rubber sleeve can reduce the sliding of the railing, prevent the railing from shaking or sliding during the placement of goods or transportation, and further improve the stability of the railing after it is laid flat.
[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 engaged with the pin shaft is also provided on the other side of the limiting plate.
[0014] The beneficial effects are: the retaining spring is clamped with the pin shaft, which can effectively prevent the pin shaft from falling off from the mounting ring during rotation or vibration. A gasket is arranged between the retaining spring and the mounting ring to buffer the contact between the retaining spring and the rotating ring, thereby preventing the retaining spring and the mounting ring on the pin shaft from repeatedly rubbing against each other during the movement of the rotating ring, causing 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 a 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 to set 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 figure marks in the drawings of the specification include: pin shaft 1, base plate 2, mounting ring 3, rotating ring 4, slot 5, limit key 6, connecting beam 7, supporting beam 8, diagonal support beam 9, reinforcing rib 10, spring 11, gasket 12, retaining spring 13, 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 in the figure 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 the 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 upper surface of the mounting ring 3 and 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 close to 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 and fixed in sequence. The connecting beam is fixed to the rotating ring 4 by welding, and a reinforcing rib 10 is 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 solid 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 laid flat. 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 sleeved 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 railing. By setting the rubber sleeve 14, on the one hand, it can buffer the impact force of the railing with the support beam every time the railing is lowered, thereby avoiding deformation of the railing during use. On the other hand, it effectively reduces the direct contact between the railing 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 railing and 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 railing. When the railing is placed on the bracket, the rubber sleeve 14 can reduce the sliding of the railing, prevent the railing from shaking or sliding during the placement of goods or transportation, and further improve the stability of the railing after it is laid flat.
[0024] like Figure 1 The bottom of the pin shaft 1 shown in the figure 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. A retaining spring 13 fixed to the end of the pin shaft 1 is also provided on the other side of the limiting plate. The retaining spring 13 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 escaping from 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 to prevent the rotating ring 4 from 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 retaining spring 13 in this embodiment can be disassembled according to the usage conditions for easy maintenance and replacement. 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 cargo compartment railing needs to be laid flat, the rotating ring 4 fixedly connected to the bracket is rotated, lifted upward and rotated to insert the limit key 6 into a slot 5. Under the action of gravity and 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, the bracket can stably support the railing, so that the flat railing has a certain supporting capacity and can be used to place and display goods. At the same time, by setting the limit key 6, even if the vehicle is moved briefly, the bracket will not rotate due to vibration, which will cause the railing to collapse and cause cargo loss. When the cargo compartment railing does not need to be laid flat, it can overcome the elastic force of the spring 11, lift it upward 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 spring 11, the bracket will not pop out and rub other vehicles around during normal driving of the vehicle, thereby ensuring driving safety. The setting of the limit key 6 and the card slot 5 makes the bracket flexible to adjust and can quickly switch between multiple states. At the same time, the locking design after the limit key 6 is inserted into the card slot 5 effectively prevents the bracket and the railing from shaking when placed horizontally, ensures the stability of the railing placement, and further improves the safety and reliability during use. The above setting can not only realize the flattening function of the tailgate of the cargo compartment, but also make the three side rails of the cargo compartment flat. The device is simple to make, low cost, easy to use, strong load-bearing capacity, and convenient to adjust.
[0027] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
