Description

Technical Field

[0001] This utility model relates to the field of door curtain technology, and more specifically, to a novel logistics channel door curtain. Background Technology

[0002] Traditional door curtains are mostly designed for people to enter and exit, and their strength and durability are relatively low. During the frequent passage of people, the door curtains are already subjected to a certain amount of pulling and friction, and are prone to damage and tearing. In logistics scenarios, in addition to the frequent passage of people, there are also forklifts, trucks and other vehicles entering and exiting. These vehicles travel at high speeds and are large in size, and the impact force they generate far exceeds the withstand range of traditional door curtains. When vehicles pass by, traditional door curtains are easily damaged, making them unusable and requiring frequent replacements. This undoubtedly increases the operating costs of logistics companies. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of logistics channel curtain that is easy to install, has high structural strength and good sealing performance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel logistics channel curtain, comprising an L-shaped installation track and a curtain fixed on the installation track. The installation track is uniformly provided with multiple sets of connecting structures for fixing the curtain. Each connecting structure includes several slots on the installation track and several buckles on the upper end of the curtain. Each buckle has a vertical limiting block at its upper end, and the entrance end of each slot has a guide groove adapted to the vertical limiting block. The vertical limiting block passes through the guide groove, causing the buckle to contact the inner wall of the slot to form a limiting fit.

[0005] The present invention is further configured such that: a fixing component is provided between the door curtain and the buckle, the fixing component includes protruding strips arranged alternately on both sides of the door curtain, a limiting block arranged between the two protruding strips and extending partially along the length of the door curtain, and a mounting plate for fixing the bolts, and the bolts are fastened to the mounting plate by passing through the buckle, the limiting block, the door curtain and the limiting block in sequence.

[0006] The present invention is further configured such that: magnetic strips are provided between the adjacent door curtains, and the magnetic strips are sleeved on both sides of the door curtains. When the door curtains fall automatically, the adjacent magnetic strips stick together to form a sealing surface.

[0007] The present invention is further configured such that the thickness of the limiting block is the same as the height of the protrusion, and the two cooperate with each other to form a plane after installation.

[0008] The present invention is further configured such that: the door curtain is provided with uniformly distributed reinforcing ribs, which may be distributed along the length direction, width direction or cross direction of the door curtain.

[0009] The present invention is further configured such that the gap between adjacent door curtains is 0.07-0.1 times the width of the door curtain.

[0010] The beneficial effects of this utility model are:

[0011] 1. The installation track features multiple evenly distributed connecting structures, including slots and buckles at the top of the curtain. During installation, workers simply align the vertical limiting block on the buckle with the guide groove at the entrance of the slot, then easily pass it through to create a limiting fit between the buckle and the inner wall of the slot. This installation method eliminates the need for complex tools and cumbersome procedures, significantly saving installation time and labor costs. Compared to traditional curtain installation methods, efficiency is significantly improved. Furthermore, the fit between the vertical limiting block and the guide groove, as well as the limiting fit between the buckle and the inner wall of the slot, effectively prevents the curtain from swaying or falling off during daily use. In logistics aisles, frequent movement of people and goods generates impact. If the curtain connection is not secure, it can easily be knocked off, affecting normal logistics operations. This new type of curtain's stable connection can withstand a certain amount of external impact, ensuring the curtain remains in the correct position and providing continuous and effective separation and protection for the logistics aisle.

[0012] 2. The staggered distribution of the raised strips effectively enhances the structural strength of both sides of the curtain. During daily use, it reduces the contact area between the curtain and logistics vehicles, extending the curtain's lifespan. It also provides additional support, preventing deformation and damage under external forces, significantly improving the overall durability of the curtain. The limiting block is positioned between the two raised strips and extends along the length of the curtain. During bolt installation, the limiting block provides precise positioning, ensuring the bolt accurately passes through the connection points—the clip, the limiting block, the curtain, and another limiting block—before securing it to the mounting plate. This not only improves installation efficiency and avoids insecure connections due to bolt misalignment but also guarantees the stability of the entire connection structure.

[0013] 3. When the curtain automatically falls, adjacent magnetic strips adhere to each other to form a sealing surface, which can prevent air circulation to a certain extent, reduce indoor temperature loss, and lower energy consumption. The thickness of the limiting block is the same as the height of the convex strip. After installation, the two work together to form a plane, which helps to distribute the external forces on the curtain during use. When the curtain is subjected to external forces such as pulling or shaking, the planar structure can more evenly transmit the force to various parts, maintaining overall stability and preventing it from easily swaying left and right or moving up and down. This avoids excessive local stress that could lead to loosening or damage to the connection, thereby further improving the stability of the curtain and the buckle connection and extending the service life of the curtain.

[0014] 4. With increased use, ordinary door curtains are prone to deformation, affecting their normal use and aesthetics. The presence of reinforcing ribs significantly improves the curtain's resistance to deformation. Even under significant external pulling or squeezing, the curtain can quickly recover its original shape under the action of the reinforcing ribs, maintaining good shape and performance. The gap between adjacent curtains is set to 0.07-0.1 times the curtain width, providing sufficient space for people and vehicles to enter and exit. This gap range is neither too large, resulting in poor sealing, nor too small, affecting passage convenience. When people or vehicles need to pass through the curtains, adjacent curtains can be easily separated for smooth passage, improving efficiency. Although there is a certain gap between adjacent curtains, when the curtains automatically lower, because the gap is within a reasonable range, the adjacent magnetic strips can still attract each other and adhere tightly, forming an effective sealing surface.

[0020] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.

[0021] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0022] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0023] Figures 1 to 4 The novel logistics channel curtain 2 shown includes an L-shaped installation track 1 and a curtain 2 fixed on the installation track 1. The installation track 1 is evenly provided with multiple sets of connecting structures for fixing the curtain 2. Each connecting structure includes several slots 3 on the installation track 1 and several buckles 4 on the upper end of the curtain 2. Each buckle 4 has a vertical limiting block 85 at its upper end. The entrance end of each slot 3 has a guide groove 6 that matches the vertical limiting block 85. During installation, workers simply align the vertical limiting block 85 on the buckle 4 with the guide groove 6 at the entrance end of the slot 3, and then easily pass it through, allowing the buckle 4 to form a limiting fit with the inner wall of the slot 3. This installation method eliminates the need for complex tools and cumbersome procedures, significantly saving installation time and labor costs. Compared to traditional curtain 2 installation methods, efficiency is significantly improved. Furthermore, the matching of the vertical limiting block 85 with the guide groove 6, and the limiting fit between the buckle 4 and the inner wall of the slot 3, effectively prevent the curtain 2 from shaking or falling off during daily use. In logistics aisles, the frequent movement of people and goods generates considerable impact. If the curtain 2 is not securely connected, it can easily be knocked down, disrupting normal logistics operations. This new type of curtain 2, with its secure connection, can withstand certain external impacts, ensuring that the curtain 2 remains in the correct position and provides continuous and effective separation and protection for the logistics aisle.

[0024] A bolted fixing assembly is provided between the curtain 2 and the buckle 4. This assembly includes staggered protrusions 7 on both sides of the curtain 2, a limiting block 8 extending between the two protrusions 7 and along the length of the curtain 2, and a mounting plate 9 for fixing the bolts. The staggered distribution of the protrusions 7 effectively enhances the structural strength of both sides of the curtain 2. During daily use, it reduces the contact area between the curtain 2 and the logistics vehicles entering and exiting, extending the service life of the curtain 2. It also provides additional support to the curtain 2, preventing deformation or damage under external forces, thus greatly improving the overall durability of the curtain 2. The limiting block 8 is located between the two protrusions 7 and extends along the length of the curtain 2. During bolt installation, the limiting block 8 provides precise positioning, ensuring that the bolt accurately passes through the connection points—the buckle 4, the limiting block 8, the curtain 2, and another limiting block 8—before being securely connected to the mounting plate 9. This not only improves installation efficiency and avoids insecure connections due to bolt installation position deviations but also ensures the stability of the entire connection structure.

[0025] Magnetic strips 10 are provided between adjacent door curtains 2. The magnetic strips 10 are sleeved on both sides of the door curtain 2. When the door curtain 2 falls automatically, the adjacent magnetic strips 10 stick together to form a sealing surface, which can prevent air circulation to a certain extent, reduce the loss of indoor temperature, and reduce energy consumption.

[0026] The thickness of the limiting block 8 is the same as the height of the protrusion 7. After installation, the two cooperate to form a plane, which helps to disperse the external force on the curtain 2 during use. When the curtain 2 is subjected to external forces such as pulling and shaking, the planar structure can transmit the force to each part more evenly, maintain the overall stability, and will not easily sway left and right or move up and down. This avoids excessive local force, which may lead to loosening or damage to the connection, thereby further improving the stability of the connection between the curtain 2 and the buckle 4 and extending the service life of the curtain 2.

[0027] The curtain 2 is also provided with evenly distributed reinforcing ribs 11, which can be distributed along the length, width, or cross direction of the curtain 2. With the increase of use time, ordinary curtains 2 are prone to deformation, affecting their normal use and aesthetics. The presence of reinforcing ribs 11 can significantly improve the deformation resistance of the curtain 2. Even under large external force of pulling or squeezing, the curtain 2 can quickly restore its original shape under the action of the reinforcing ribs 11, maintaining good shape and performance.

[0028] When the gap between adjacent curtains 2 is less than 0.07 times the width of curtain 2, it becomes very difficult for people or vehicles to pass through. People may frequently bump into curtains 2 when entering or exiting, especially when carrying vehicles or wearing loose clothing. Curtains 2 will constantly obstruct passage, increasing passage time and difficulty. They may even be damaged or the magnetic strips 10 may detach due to pulling. For moving large items, the narrow gap is simply insufficient, requiring extra effort to separate the curtains 2, reducing work efficiency. When the gap between adjacent curtains 2 is greater than 0.1 times the width of curtain 2, the sealing surface formed by the magnetic strips 10 will be affected. When the curtains 2 automatically lower, the attraction between the magnetic strips 10 may be insufficient due to the large gap. Completely overcoming the separation tendency caused by gaps prevents the magnetic strips 10 from fitting tightly, resulting in gaps. This would significantly reduce the heat insulation, sound insulation, dustproofing, and insect-proofing functions of the curtain 2. Therefore, the optimal gap between adjacent curtains 2 is 0.07-0.1 times the width of the curtain 2. This provides sufficient space for people and vehicles to enter and exit. This gap range is neither too large, resulting in poor sealing, nor too small, affecting the convenience of passage. When people or vehicles need to pass through the curtain 2, they can easily separate the adjacent curtains 2 and pass smoothly, improving passage efficiency. Although there is a certain gap between adjacent curtains 2, when the curtain 2 automatically falls, because the gap is within a reasonable range, the adjacent magnetic strips 10 can still attract each other and stick tightly together, forming an effective sealing surface.

Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
