Description

Technical Field

[0001] This utility model relates to the field of isolation fence technology, specifically to an isolation fence device for logistics freight yards. Background Technology

[0002] With the explosive growth of e-commerce and the deepening of globalization, the modern logistics industry is undergoing a dual transformation of soaring throughput and improved operational efficiency. As a key node in the logistics network, freight yards undertake the core functions of cargo collection, distribution, storage, and turnover. Their zoning, security, and operational efficiency directly affect the smoothness of the entire logistics chain. Against this backdrop, freight yard fencing, as an infrastructure for space management, faces increasingly stringent performance requirements.

[0003] Existing logistics yard fencing consists of posts and netting. During on-site installation, the two need to be fixedly connected. Currently, most fences use multiple sets of bolts for fixing. Specifically, the mounting plates on the edge of the netting are aligned with the mounting plates on the edge of the posts, and then bolts are inserted and locked. Each piece of fencing requires 4-6 bolts. If multiple pieces of fencing are combined to enclose an area, even more bolts are needed, which significantly reduces installation efficiency. In addition, there are often transfer vehicles passing through the yard, and the middle area of ​​the fencing is relatively weak. Currently, the fencing on the market does not have reinforcement support in this area. Once a transfer vehicle collides with the fencing, it is very easy for the middle area of ​​the fencing to deform and be damaged. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a logistics yard isolation fence device to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a logistics yard isolation fence device, comprising a column and a frame, wherein the outer surface of the column is provided with an installation groove, the two sides of the frame are fixed with installation strips, and a limit groove is started above one side of the installation strips, the top of the column is threadedly connected with a screw rod, and the bottom end of the screw rod is fixed with a compression ball, the inner wall of the column is connected with a pressure ball by a spring, and a limit rod is fixed on one side of the pressure ball; an installation block is fixed in the middle of the outer surface of the frame, and a support plate is installed on the inner side of the installation block by an installation shaft.

[0006] Furthermore, a base is fixed to the bottom of the column, and the longitudinal section of the base is trapezoidal.

[0007] By adopting the above technical solution, the trapezoidal base at the bottom of the column can increase the contact area with the ground, significantly improve the stability of the column after installation, and effectively reduce the tilting or falling of the column caused by external force collision.

[0008] Furthermore, the frame is slidably engaged with the mounting groove via a mounting strip, and the cross-sections of the mounting strip and the mounting groove are T-shaped.

[0009] By adopting the above technical solution, the frame slides into the mounting groove through the "T"-shaped mounting strip, ensuring the structure is stable after installation and preventing shaking and loosening.

[0010] Furthermore, a mesh is fixed to the inner side of the frame, and the mesh is made of low-carbon steel wire.

[0011] By adopting the above technical solutions, low-carbon steel wire has good plasticity and toughness, is easy to process and form, and has a low cost; at the same time, after surface treatment, it can have a certain degree of corrosion resistance, which can meet the basic usage requirements of freight yard isolation fencing.

[0012] Furthermore, the support plate is in the shape of a right triangle, and mounting plates are fixed on both sides of the bottom of the support plate. Mounting holes are passed through the top of both the mounting plates and the base.

[0013] By adopting the above technical solution, the support plate is in the shape of a right triangle, which can further enhance the support strength of the middle area of ​​the frame by means of the stability of the triangle; the mounting plates on both sides of its bottom are matched with the mounting holes that pass through the top of the base, which makes it easy to fix to the ground with expansion bolts, thus improving the convenience of installation and the stability of the overall structure.

[0014] Furthermore, a magnetic sheet is embedded on one side of the support plate, and the frame is made of low-carbon steel.

[0015] By adopting the above technical solution, the magnetic sheet is combined with the frame made of low carbon steel. During transportation, the support plate is flipped so that the magnetic sheet can be firmly attached to the frame, preventing the support plate from shaking. This greatly improves the stability and convenience during transportation, while reducing the damage caused by collisions between components.

[0016] Furthermore, the mounting slots are provided in four groups, and the four groups of mounting slots are evenly distributed in a rectangular array.

[0017] By adopting the above technical solution, the four sets of mounting slots can adapt to the frame installation requirements in different directions. In particular, at the corners, precise docking of the mesh in each direction can be achieved, ensuring a smooth and efficient installation process and improving the overall regularity of the enclosed area.

[0018] Furthermore, a knob is fixed to the top of the screw.

[0019] By adopting the above technical solution, the knob provides a convenient point of force for the operator to turn the screw, and can easily control the movement of the squeeze ball.

[0020] Furthermore, the spring is provided in four sets, and all four sets of springs are made of manganese steel.

[0021] By adopting the above technical solution, the four sets of springs can form a uniform and stable elastic support for the compressed ball, ensuring that the limit rod moves synchronously and accurately; the springs made of manganese steel have excellent elastic recovery performance and fatigue resistance, and can withstand repeated deformation for a long time without easily failing, thus extending the service life of the device.

[0022] Furthermore, one end of the limiting rod penetrates through the inner wall of the column, and one end of the limiting rod is on the same plane as the inner wall of the mounting groove, and the limiting rod is adapted to the limiting groove.

[0023] By adopting the above technical solution, one end of the limiting rod penetrates through the inner wall of the column and is on the same plane as the inner wall of the mounting groove, which can avoid obstructing the insertion of the mounting strip and ensure a smooth installation process; at the same time, the limiting rod and the limiting groove are compatible to achieve precise engagement, further improving the stability of the connection between the frame and the column and preventing loosening and displacement.

[0024] In summary, the present invention has the following main advantages: 1. This utility model, comprising an installation groove, installation strip, extrusion ball, pressure ball, spring, limiting rod, limiting groove, and screw, allows for easy installation. During installation, workers simply insert the installation strip from the frame into the installation groove of the column. After enclosing multiple sets of isolation netting, they turn the knobs on the columns one by one. The knobs rotate the screw, causing the extrusion ball to move upwards and compress the pressure ball. The pressure ball overcomes the spring force, pushing the limiting rod outwards and precisely embedding it into the limiting groove of the installation strip, thus quickly and securely fixing the frame. The entire process is simple to operate, eliminating the need for cumbersome bolt tightening and significantly reducing... This invention significantly reduces installation time and improves construction efficiency. When disassembly is required later (e.g., during yard renovation), workers can reverse the knob, causing the screw to move the compression ball downwards, releasing the pressure on the ball. At this point, the spring returns to its original position, driving the compression ball to simultaneously disengage multiple limit rods from the limit groove. Workers can then easily slide the mounting strips from the mounting groove on the frame to complete disassembly. Compared to traditional bolt connections, this invention achieves efficient two-way operation for both installation and disassembly, meeting the needs of rapid yard construction while providing flexibility and convenience for later modifications, demonstrating significant practical value. 2. This utility model features an installation shaft, a support plate, a magnetic sheet, and a triangular mounting plate. During the transportation of the isolation net, the magnetic sheet firmly adheres the support plate to the frame, ensuring a tight fit between the support plate and the frame. This effectively reduces space occupation during transportation and prevents damage caused by swaying of the support plate, making the transportation process more convenient and efficient. During the installation phase, workers can easily flip the support plate using the installation shaft. At this point, the magnetic sheet naturally separates from the frame, and the support plate forms a stable right angle with the frame. Subsequently, expansion bolts are used to fix the mounting plate to the ground. The stable structure of the triangular support plate provides strong support to the central area of ​​the frame, significantly enhancing the structural strength of the central area. Even in the event of accidental collisions with transport trolleys, it can effectively resist impact forces, greatly reducing the probability of frame deformation and bending, thereby extending the service life of the isolation net and ensuring the stability of the cargo area isolation.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] Example 1: A logistics yard isolation fence device, such as Figures 1-5As shown, the system includes a column 1 and a frame 2. A base 18 is fixed to the bottom of the column 1, and the longitudinal section of the base 18 is trapezoidal. The trapezoidal base 18 at the bottom of the column 1 increases the contact area with the ground, significantly improving the stability of the column 1 after installation and effectively reducing the tilting or falling of the column 1 due to external impacts. A mesh 3 is fixed to the inner side of the frame 2. The mesh 3 is made of low-carbon steel wire, which has good plasticity and toughness, is easy to process and form, and has a low cost. After surface treatment, it also has a certain degree of corrosion resistance, meeting the requirements for cargo yard isolation. The basic requirements for the use of the fencing include: an installation groove 4 on the outer surface of the post 1; installation strips 5 fixed on both sides of the frame 2; a limit groove 8 on one side of the installation strip 5; a screw 9 threadedly connected to the top of the post 1; a knob 14 fixed to the top of the screw 9; the knob 14 provides a convenient force point for the operator to rotate the screw 9, easily controlling the movement of the compression ball 10; a compression ball 10 fixed to the bottom of the screw 9; and a pressure ball 12 connected to the inner wall of the post 1 via a spring 13, with a limit rod 11 fixed to one side of the pressure ball 12.

[0030] See Figures 1-4 In the above embodiment, the frame 2 is slidably engaged with the mounting groove 4 via the mounting strip 5, and the cross-sections of the mounting strip 5 and the mounting groove 4 are "T" shaped. The frame 2 is slidably engaged with the mounting groove 4 via the "T" shaped mounting strip 5, which ensures that the structure is stable after installation and prevents shaking and loosening.

[0031] See Figure 1 , Figure 2 and Figure 4 In the above embodiment, the mounting slot 4 is provided in four sets, and the four sets of mounting slot 4 are evenly distributed in a rectangular array. The four sets of mounting slot 4 can adapt to the installation requirements of the frame 2 in different directions. In particular, at the corner, the precise docking of the mesh in each direction can be achieved, ensuring a smooth and efficient installation process and improving the overall regularity of the enclosed area.

[0032] See Figures 3-5 In the above embodiment, the spring 13 is provided in four sets, and all four sets of spring 13 are made of manganese steel. The arrangement of the four sets of spring 13 can form a uniform and stable elastic support for the compressed ball 12, ensuring that the movement of the limit rod 11 is synchronous and accurate. The spring 13 made of manganese steel has excellent elastic recovery performance and fatigue resistance, and can withstand repeated deformation for a long time without easily failing, thus extending the service life of the device.

[0033] See Figures 3-5In the above embodiment, one end of the limiting rod 11 penetrates the inner wall of the column 1, and one end of the limiting rod 11 is on the same plane as the inner wall of the mounting groove 4. The limiting rod 11 is adapted to the limiting groove 8. The fact that one end of the limiting rod 11 penetrates the inner wall of the column 1 and is on the same plane as the inner wall of the mounting groove 4 can avoid obstructing the insertion of the mounting strip 5 and ensure a smooth installation process. At the same time, the matching of the limiting rod 11 and the limiting groove 8 can achieve precise engagement, further improving the stability of the connection between the frame 2 and the column 1 and preventing loosening and displacement.

[0034] Example 2: To strengthen the isolation net and make its frame less susceptible to damage from impacts, Example 2 is an improvement upon Example 1. (See attached document.) Figure 1 , Figure 2 and Figure 6 A mounting block 15 is fixed to the middle of the outer surface of the frame 2, and a support plate 7 is mounted on the inner side of the mounting block 15 via a mounting shaft 6. The support plate 7 is in the shape of a right-angled triangle, and mounting plates 17 are fixed to the bottom two sides of the support plate 7. Mounting holes are passed through the top of both the mounting plate 17 and the base 18. The right-angled triangle shape of the support plate 7 can further enhance the support strength of the middle area of ​​the frame 2 by utilizing the stability of the triangle. The mounting plates 17 on both sides of its bottom cooperate with the mounting holes passed through the top of the base 18, which facilitates fixing to the ground with expansion bolts, improving the convenience of installation and the stability of the overall structure. A magnetic sheet 16 is embedded on one side of the support plate 7, and the frame 2 is made of low-carbon steel. The magnetic sheet 16 cooperates with the low-carbon steel frame 2. When the support plate 7 is flipped during transportation, the magnetic sheet 16 can be firmly attracted to the frame 2, preventing the support plate 7 from shaking, greatly improving the stability and convenience during transportation, and reducing the damage caused by collisions between components. The implementation principle of this utility model is as follows: During the transportation of the isolation net, the magnetic sheet 16 can firmly attract the support plate 7 to the frame 2, making the support plate 7 and the frame 2 fit tightly together, effectively reducing the space occupied during transportation and avoiding damage caused by the shaking of the support plate 7; During the installation stage, the staff only needs to insert the installation strip 5 on the frame 2 into the installation groove 4 of the column 1. After completing the enclosure of multiple sets of isolation nets, the staff turns the knob 14 on the column 1 one by one. The knob 14 drives the screw 9 to rotate, causing the compression ball 10 to move upward and compress the pressure ball 12. The pressure ball 12 overcomes the elastic force of the spring 13 and pushes the limiting rod 11 outward to accurately embed into the limiting groove 8 of the installation strip 5, thereby quickly and stably fixing the frame 2; Then, the staff can flip the support plate 7 through the installation shaft 6. At this time, the magnetic sheet 16 and the frame 2 naturally separate, and the support plate 7 forms a stable right angle with the frame 2. Then, the installation plate 17 is fixed to the ground with expansion bolts. With the stable structure of the triangular support plate 7, a strong support can be formed for the middle area of ​​the frame 2.
