Description

Technical Field

[0001] This invention relates to the field of refrigerated truck technology, and in particular to an embedded cargo fixing waist-mounting structure for refrigerated trucks. Background Technology

[0002] As the core equipment for cold chain logistics, refrigerated truck compartments must maintain a low-temperature environment while ensuring the stability of goods during transportation. This prevents goods from shifting or colliding due to bumps or sudden braking, which could affect the quality of cold chain goods. Cargo securing devices are crucial components of refrigerated truck compartments; their rationality directly impacts transportation efficiency and cargo safety. Therefore, a structural design with strong adaptability, ease of operation, and neat storage is essential.

[0003] Existing cargo securing devices in refrigerated trucks have several shortcomings: First, the height adjustment of the interception mechanism is inflexible. Some devices have a fixed height, making them unsuitable for cargo of different stacking heights. Adjustable structures are cumbersome to operate and lack sufficient precision, failing to accurately meet securing requirements. Second, the barrier components are inconvenient to store, easily scattering when not in use, occupying valuable storage space and affecting cargo stacking efficiency. Furthermore, the winding and unfolding of the barrier strips often relies on manual dragging, which is time-consuming and labor-intensive. Therefore, there is an urgent need to develop an adjustable sleeve that can flexibly adapt to the securing needs of cargo of different heights. The waist-band can be wound around a pivot for storage and secured with magnetic strips to prevent scattering, without occupying storage space. When in use, it is pulled out and passed through the connecting ring of the second securing frame to form an interception, effectively preventing cargo displacement. The overall structure is simple, easy to operate, and can efficiently meet the cargo securing needs of refrigerated trucks. This embedded cargo securing waist-band structure overcomes the shortcomings of current applications and meets current requirements. Summary of the Invention

[0004] The purpose of this invention is to provide an embedded cargo fixing waist-mounting structure in a refrigerated truck compartment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A refrigerated truck compartment embedded cargo fixing waist-binding structure includes a first fixing frame, an adjusting sliding sleeve, a limiting mechanism, a blocking mechanism, and a second fixing frame. The first and second fixing frames are respectively fixed to the left and right sides of the inner wall of the refrigerated truck compartment by screws. The adjusting sliding sleeve is slidably installed on the first fixing frame. The adjusting sliding sleeve is equipped with a limiting mechanism that penetrates the first fixing frame. The blocking mechanism includes: a rotating shaft, a waist-binding belt, a small magnetic strip, and a large magnetic strip. The rotating shaft is rotatably connected to one side of the adjusting sliding sleeve. The waist-binding belt is wrapped around the rotating shaft. One end of the waist-binding belt is fixed to the rotating shaft, and the other end is movably disposed. The movable end of the waist-binding belt is fixed with a small magnetic strip. The large magnetic strip is fixed to the adjusting sliding sleeve and is used to attract the small magnetic strip. The second fixing frame is fixed with multiple connecting rings, and the connecting rings are used for the movable end of the waist-binding belt to pass through.

[0006] Preferably, the limiting mechanism includes a pull plate, pins, and springs. Two pins that slide through the adjusting sleeve and the first fixing frame are fixed on the pull plate. The first fixing frame has a plurality of pin holes for the pins to pass through. A spring is installed on the outside of each pin. One end of the spring is fixed to the pull plate and the other end is fixed to the adjusting sleeve.

[0007] Preferably, the distance between two adjacent pin holes is 5 cm.

[0008] Preferably, both the first and second fixing frames are made of aluminum alloy.

[0009] Preferably, a rotating handle is fixed to the upper end of the rotating shaft.

[0010] The beneficial effects of this invention are as follows: The refrigerated truck compartment embedded cargo fixing waist-band structure fixes the first fixing frame and the second fixing frame to the left and right sides of the inner wall of the refrigerated truck compartment with screws. When not in use, the waist-band is wrapped around the rotating shaft, and the large magnetic strip attracts the small magnetic strip to prevent the waist-band from scattering, thus not affecting the storage space inside the compartment. When in use, the waist-band on the rotating shaft is pulled outwards, the movable end of the waist-band is passed through the connecting ring and tied to the connecting ring, so that the waist-band forms a barrier inside the compartment to block the cargo. In addition, before use, the pull plate is pulled to move the pin out of the pin hole, and then the adjusting sleeve is moved up and down to adjust the blocking height of the waist-band to meet the needs of cargo of different heights. After adjustment, the pin is inserted into the pin hole. In summary, this invention, through its adjustable sliding sleeve that can slide up and down, can flexibly adapt to the fixing needs of goods of different heights; the waist belt can be wrapped around the pivot for storage, and is fixed with magnetic strips to prevent it from scattering, without occupying storage space in the compartment. When in use, it can be pulled out and passed through the connecting ring of the second fixing frame to form an interception, effectively preventing the goods from shifting. The overall structure is simple and easy to operate, and can efficiently meet the needs of fixing goods in refrigerated compartments. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Specific implementation examples are given below.

[0019] See Figures 1 to 5 As shown, this invention provides an embedded cargo fixing structure for refrigerated truck compartments. In practical applications, it can be completely installed on both side walls inside a standard refrigerated truck compartment, achieving lateral interception and fixing of cold chain goods of varying stack heights. The specific embodiments of this invention are described in detail below with reference to the accompanying drawings and component reference numerals. Figure 1 As shown, the overall structure includes a first fixed frame 1, an adjusting sliding sleeve 2, a limiting mechanism 3, a blocking mechanism 4, and a second fixed frame 5. The first fixed frame 1 and the second fixed frame 5 are symmetrically fixed to the left and right sides of the inner wall of the refrigerated truck compartment by screws. Both are made of aluminum alloy profiles with a "U" shaped cross-section, ensuring structural strength while effectively reducing overall weight. Furthermore, their outer surfaces are flush with or slightly lower than the inner wall plane, ensuring no scratching or interference during loading and unloading, and maximizing the utilization of the truck compartment's internal volume. Figure 3 As shown, in the installed state, the first fixing frame 1 and the second fixing frame 5 are arranged symmetrically, so that the subsequent tensioned waist belt 402 is subjected to uniform force, avoiding structural deformation caused by eccentric loading.

[0020] The adjusting sleeve 2 is slidably mounted on the first fixed frame 1, and slides freely up and down along the longitudinal direction of the first fixed frame 1. For example... Figure 4 and Figure 5 As shown, the adjusting sleeve 2 is a rectangular shell structure with an internal groove that matches the outer contour of the first fixed frame 1, allowing the adjusting sleeve 2 to slide smoothly on the first fixed frame 1 without wobbling. A rotating shaft 401 is rotatably connected to one outer surface of the adjusting sleeve 2. The rotating shaft 401 is mounted on the right side of the adjusting sleeve 2 via a bearing or shaft hole fit. Figure 1 (From a viewing angle), a rotating handle 4011 is fixedly connected to its upper end, allowing the operator to manually rotate and rewind or release the waist belt 402. One end of the waist belt 402 is fixedly wrapped around the outer circumference of the rotating shaft 401, while the other end is a free-moving end. It can be pulled out from the rotating shaft 401 during use and rolled back onto the rotating shaft 401 by rotating the handle 4011 when not in use. The waist belt 402 is made of high-strength polyester fiber woven strap, with a width of 80 mm and a thickness of 2 mm. The surface has anti-slip texture to enhance friction with the contact surface of the goods and prevent slippage due to sudden braking or turning during transportation.

[0021] like Figure 1 and Figure 5 As shown, a small magnetic strip 403 is fixedly connected to the movable end of the waist belt 402, while a large magnetic strip 404 is fixedly connected to the outer surface of the adjusting sleeve 2 near the rotating shaft 401. Both the small magnetic strip 403 and the large magnetic strip 404 are made of neodymium iron boron permanent magnet material and are covered with a low-temperature resistant rubber sleeve, which can adapt to the working environment of -25℃ to +10℃ in the refrigerated compartment. The magnetic area of ​​the large magnetic strip 404 is larger than that of the small magnetic strip 403, ensuring that after the waist belt 402 is fully rolled up, the small magnetic strip 403 can completely cover the effective magnetic attraction area of ​​the large magnetic strip 404, forming a stable and reliable magnetic connection. This magnetic structure ensures that when not in use, the movable end of the waist belt 402 is firmly attracted to the surface of the adjusting sleeve 2, preventing the waist belt 402 from sagging, scattering, or occupying cargo stacking space due to compartment vibration, thereby keeping the interior of the compartment neat and orderly.

[0022] like Figure 2 and Figure 3As shown, multiple connecting rings 501 are equidistantly fixed on the outer side of the second fixing frame 5 along the longitudinal direction. Each connecting ring 501 is a closed metal ring with an inner diameter of 25 mm, and is firmly installed on the second fixing frame 5 by riveting. Its axis is parallel to the transverse direction of the carriage. The vertical distance between adjacent connecting rings 501 is 5 cm, which is consistent with the distribution distance of the pin holes 101 on the first fixing frame 1, ensuring that there is a corresponding connecting ring 501 for the waist belt 402 to pass through at any height adjustment. In use, the operator pulls the movable end of the waist belt 402 horizontally out from the rotating shaft 401, passes it through the connecting ring 501 corresponding to the current height of the adjusting sleeve 2, and then fixes the movable end of the waist belt 402 to the connecting ring 501 by knotting, buckling, or re-threading, thereby forming a transversely tensioned intercepting belt inside the carriage, applying a transverse restraint force to the stacked goods, and effectively preventing them from shifting in the front-back or left-right directions due to bumps, turns, or sudden braking during vehicle operation.

[0023] like Figure 4 and Figure 5 As shown, the limiting mechanism 3 is installed on the adjusting sleeve 2 and penetrates the adjusting sleeve 2 to cooperate with the first fixed frame 1, used to lock the adjusting sleeve 2 in a specific position on the first fixed frame 1. The limiting mechanism 3 includes a pull plate 301, two pins 302, and two springs 303. The pull plate 301 is located on the side of the adjusting sleeve 2 away from the inner wall of the carriage, and its two ends are respectively fixedly connected to two pins 302. The two pins 302 slide horizontally through the side wall of the adjusting sleeve 2 and continue to extend into the interior of the first fixed frame 1. The first fixed frame 1 has a plurality of pin holes 101 evenly distributed along its longitudinal center line, and the center distance between adjacent pin holes 101 is 5 cm. The pins 302 can be selectively inserted into any pin hole 101 to achieve height locking. A spring 303 is sleeved on the outer periphery of each pin 302. One end of the spring 303 abuts against the inner side surface of the pull plate 301, and the other end abuts against the inner side wall of the adjusting sleeve 2. In its natural state, the spring 303 is compressed, pushing the pin 302 toward the first fixing bracket 1, so that the pin 302 remains in the locked state of being inserted into the pin hole 101.

[0024] When the height of the barrier needs to be adjusted, the operator performs S1: pulling the pull plate 301 outward to overcome the elastic force of the spring 303, causing the two pins 302 to simultaneously disengage from the current pin hole 101. At this time, the adjusting sleeve 2 can slide freely up and down on the first fixed frame 1. After adjusting to the target height, the pull plate 301 is released, and the pins 302 are reinserted into the corresponding pin holes 101 under the reset action of the spring 303, completing the height locking. Due to the symmetrical arrangement of the double pins 302, combined with the bidirectional reset force of the spring 303, even in a transportation vibration environment, the pins 302 will not accidentally disengage from the pin holes 101, ensuring the long-term stability and reliability of the structure. For example, when transporting a batch of frozen food with a stack height of 100 cm, the operator can adjust the adjusting sleeve 2 to the position of the pin hole 101 corresponding to the 100 cm height, so that the waist belt 402 is exactly located in the middle of the stacked goods, providing the best lateral restraint effect.

[0025] After adjusting the height, the operator performs S2: holding the rotating handle 4011 and rotating it counterclockwise to release the waist belt 402 from the rotating shaft 401. The movable end of the waist belt 402 is then pulled horizontally out and passed through the connecting ring 501 on the second fixing frame 5, corresponding to the current height. Then, S3 is performed: the movable end of the waist belt 402 is wrapped around the connecting ring 501 and knotted for fixation, or it is locked to the connecting ring 501 using an additional quick-release buckle, forming a taut horizontal interception belt. The entire operation requires no tools and can be completed by a single person within 30 seconds, suitable for high-frequency loading and unloading operations in cold chain logistics. When not in use, the operator simply needs to unfasten the fixed end of the waist belt 402 and rotate the rotating handle 4011 clockwise to completely retract the waist belt 402 onto the rotating shaft 401. At this time, the small magnetic strip 403 automatically attaches to the large magnetic strip 404, achieving neat storage.

[0026] Specifically, the rotational connection between the rotating shaft 401 and the adjusting sleeve 2 adopts a non-self-locking structure, meaning it can rotate freely without external force, facilitating the quick pull-out of the waist belt 402. Simultaneously, a friction damping plate or a small ratchet mechanism can be installed inside the rotating handle 4011 to provide moderate resistance during winding, preventing the waist belt 402 from automatically unfolding due to gravity or inertia. Furthermore, all structural components are embedded, with no protruding parts, ensuring that goods can be stacked tightly against the side walls of the carriage without reducing effective loading space due to the presence of the fixing device. In summary, this invention, through the sliding cooperation between the adjusting sleeve 2 and the first fixing frame 1, the multi-position locking of the limiting mechanism 3, the magnetic absorption of the blocking mechanism 4, and the corresponding arrangement of the connecting ring 501 on the second fixing frame 5, achieves highly flexible adjustment, neat storage, easy operation, and reliable cargo fixing functions, fully meeting the comprehensive requirements of refrigerated carriages for cargo stability, space utilization, and operational efficiency in actual cold chain transportation.

[0027] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0028] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
