Description

Technical Field

[0001] This invention relates to the field of fencing technology, specifically to a retractable fencing device that is fixed to a steel tower. Background Technology

[0002] Fences are generally divided into fixed fences and movable fences. Movable fences are more widely used mainly because they are portable and easy to use. There are many types of movable fences with different uses.

[0003] One type of movable fence is the telescopic fence, which includes a support frame, folding fences, and the two sides of the folding fences are fixed to the support frame. However, this type of fence is relatively complicated to manufacture, and the finished fence generally consists of two layers of fences that are interlocked, making the process quite complex and inconvenient for mass production. In addition, the telescopic fence narrows when it is extended, resulting in a small protection range and requiring a large number of fences to cooperate, which leads to a waste of money. Therefore, it is very necessary to propose a telescopic fence device that can be fixed on a steel tower. Summary of the Invention

[0004] (1) Technical problems solved

[0005] To address the shortcomings of existing technologies, this invention provides a retractable fence device fixed to a steel tower. The main solution is to address the problems that finished fences typically consist of two layers, which are interlocked and complex to manufacture, making mass production inconvenient. Additionally, retractable fences narrow when extended, resulting in a smaller protective range and requiring a large number of fences, leading to a waste of funds.

[0006] (2) Technical solution

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A retractable fence device fixed to a steel tower includes an upper fence layer and a lower fence layer. Both the upper and lower fence layers include a plurality of fence bars that are on the same plane and parallel to each other. The fence bars of the upper fence layer are installed on one side of the fence bars of the lower fence layer by fasteners. The fasteners are located at the contact points between the fence bars of the upper and lower fence layers.

[0009] Furthermore, the fastener is any one of a pin, rivet, or bolt.

[0010] Based on the aforementioned scheme, a decorative layer is provided on the outer side of each of the fence posts.

[0011] As a further embodiment of the present invention, the decorative layer is an artificial plant, and the decorative layer is connected and fixed to the fence post by a fixing strap.

[0012] Furthermore, the fixing strap is either a nylon hook and loop fastener or a binding strap.

[0013] Based on the aforementioned scheme, it also includes two fixed rods. Each of the two fixed rods has a guide groove on one of its opposing sides. Multiple sliding rods are slidably connected in the guide grooves. The multiple sliding rods are hollow structures. Multiple cross arms are provided between two adjacent sliding rods. Sliding grooves are provided on the inner walls of both sides of the multiple sliding rods. The two ends of the multiple cross arms are rotatably connected to two adjacent sliding rods respectively. Connecting shafts are slidably connected in the multiple sliding grooves respectively. The other two ends of the multiple cross arms are rotatably connected to two vertically opposing connecting shafts respectively. A self-locking component for fixing the extension height of the fence is provided on the outer wall of one side of the uppermost sliding rod. Multiple first connecting ears are fixedly connected to one side of one of the fixed rods, and multiple second connecting ears are fixedly connected to one side of the other fixed rod. Insert rods are inserted into the multiple second connecting ears, and the insert rods can be inserted into the first connecting ears, so that the two fences can be combined and bent through the first connecting ears and the second connecting ears. A stop component for limiting the insertion rod is provided on the outer side of the insert rod near the bottom. Mounting bases are fixedly connected to the bottom ends of both fixed rods.

[0014] As a further embodiment of the present invention, the self-locking assembly includes two fixing brackets, both of which are fixedly connected to the outer wall of the uppermost slide rod at both ends. A tension spring is fixedly connected to one side of each of the two fixing brackets, and a plug is fixedly connected to one end of the tension spring. A sliding hole is provided on one side of each of the two fixing brackets, and the plug passes through the sliding hole. Multiple slots are provided on one side of each of the two fixing rods, and the plug engages with the slots. A second inclined surface is provided on the upper surface of the plug.

[0015] Furthermore, the blocking component includes two sliding openings, which are symmetrically opened on the outer circumference of the insert rod. A slider is slidably connected in each of the two sliding openings. The bottom of the slider is provided with a first inclined surface. A spring is fixedly connected in each of the two sliding openings, and the spring is fixed to the slider. An extension plate is integrally formed at the top of the insert rod.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a retractable fence device fixed on a steel tower, which has the following advantages:

[0018] 1. The retractable fence of the present invention has the characteristics of simple structure, convenient use, ingenious concept and novel design. The overall structure is easy to manufacture, which can shorten the manufacturing process. It has a good three-dimensional effect, strong practicality, wide range of applications and is easy to promote.

[0019] 2. By using the cross arm and the slide rail in combination, the cross arm will rotate when the fence is stretched. At the same time, the cross arm will rotate with the slide rail and the cross arm will rotate with the connecting shaft, causing the connecting shaft to move along the slide rail. This prevents the fence from narrowing when stretched, thereby increasing the fence's protection range and saving costs.

[0020] 3. With the self-locking component, when the fence is stretched to a suitable height, the self-locking component will automatically lock and fix the height of the fence, making it easier for staff to use and improving the convenience of fence use.

[0021] 4. By using the first connecting ear, the second connecting ear, and the plug rod together, when encountering a corner, the two fences are combined to a suitable angle for the corner. The first connecting ear on one fence is aligned vertically with the second connecting ear on the other fence. Then, the plug rod is inserted into the first and second connecting ears to assemble the two fences. This allows the fences to protect the corner, making them suitable for different environments and improving their effectiveness. Attached Figure Description

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] Example 1

[0033] Reference Figures 1-2 A retractable fence device fixed to a steel tower includes an upper fence layer 1 and a lower fence layer 2. Both the upper fence layer 1 and the lower fence layer 2 include several fence bars 6 that are parallel to each other and on the same plane. The fence bars 6 of the upper fence layer 1 are installed on one side of the fence bars 6 of the lower fence layer 2 by fixing members 3. The fixing members 3 are set at the contact points between the fence bars 6 of the upper fence layer 1 and the fence bars 6 of the lower fence layer 2. The lower fence layer 2 is formed by arranging multiple fence bars 6 in parallel, and then the upper fence layer 1 is formed by arranging another multiple fence bars 6 in parallel above the lower fence layer 2. The contact points of the upper fence layer 1 and the lower fence layer 2 are then connected by the fixing members 3 to form a fence. It has the characteristics of simple structure, convenient use, ingenious concept, and novel design. The overall structure is easy to manufacture, which can shorten the manufacturing process. It has a good three-dimensional effect, strong practicality, wide applicability, and is easy to promote.

[0034] In this invention, the fixing member 3 is a rivet, and a decorative layer 5 is provided on the outer side of each of the multiple fence posts 6. The decorative layer 5 is an artificial plant. The decorative layer 5 is connected and fixed to the fence post 6 by a fixing strap 4. In this embodiment, the fixing strap 4 is a nylon hook and loop fastener. Installing the decorative layer 5 on the outer side of the fence post 6 by fixing the strap 4 can make the entire fence look more three-dimensional and provide a good enclosure effect.

[0035] The working principle of this embodiment is as follows: In use, multiple fence posts 6 are arranged in parallel to form a lower fence layer 2. Then, multiple more fence posts 6 are arranged in parallel above the lower fence layer 2 to form an upper fence layer 1. The contact parts of the upper fence layer 1 and the lower fence layer 2 are then connected by fasteners 3 to form a fence. It has the characteristics of simple structure, convenient use, ingenious concept, and novel design. The overall structure is easy to manufacture, which can shorten the manufacturing process. It has a good three-dimensional effect, strong practicality, wide applicability, and is easy to promote. At the same time, the decorative layer 5 is installed on the outside of the fence posts 6 by fixing straps 4, which can make the entire fence look more three-dimensional and have a good enclosure effect.

[0036] Example 2

[0037] Reference Figures 3-8 A retractable fence device fixed to a steel tower includes two fixed rods 25. Each fixed rod 25 has a guide groove 8 on one opposite side. Multiple sliding rods 7 are slidably connected within the guide grooves 8. All sliding rods 7 are hollow. Multiple cross arms 18 are provided between adjacent sliding rods 7. Sliding grooves 19 are provided on the inner walls of both sides of each sliding rod 7. The two ends of each cross arm 18 are rotatably connected to two adjacent sliding rods 7. Connecting shafts are slidably connected within each sliding groove 19. The other two ends of each cross arm 18 are rotatably connected to two vertically opposite connecting shafts. Pulling the uppermost sliding rod 7 upwards along the guide groove 8 causes the cross arms 18 to rotate during the movement. The two ends of the cross arm 18 rotate with the slide bar 7, while the other two ends of the cross arm 18 rotate with the connecting shaft, causing the connecting shaft to move along the slide groove 19. When the connecting shaft moves to the other end of the slide groove 19, the cross arm 18 stops rotating, and the slide bar 7 continues to move upward, thus pulling the lower slide bar 7 upward through the cross arm 18. This cycle repeats, thereby stretching the fence. When stretching the fence, since the other two ends of the cross arm 18 move within the slide groove 19 through the connecting shaft, the fence does not become narrower, thereby increasing the protection range of the fence and saving costs. The outer wall of one side of the uppermost slide bar 7 is provided with a self-locking component to fix the extension height of the fence.

[0038] One of the fixing rods 25 has multiple first connecting ears 9 welded to one side, and the other fixing rod 25 has multiple second connecting ears 11 welded to one side. Each of the multiple second connecting ears 11 has a plug rod 12 inserted into it, and the plug rod 12 can be inserted into the first connecting ears 9. This allows the two fences to be combined and bent through the first connecting ears 9 and the second connecting ears 11. When encountering a corner, the two fences are combined, and the first connecting ears 9 on one fence are aligned vertically with the second connecting ears 11 on the other fence. Then, the plug rod 12 is inserted into the first connecting ears 9 and the second connecting ears 11, thereby connecting the two fences. This allows the fence combination to bend and protect the corner. The outer side of the plug rod 12 is provided with a stop component near the bottom to limit the plug rod 12. The bottom ends of both fixing rods 25 are welded with mounting bases 10.

[0039] Specifically, the self-locking assembly includes two fixing brackets 22, both of which are bolted to the outer wall of the uppermost slide rod 7 at both ends. A tension spring 20 is welded to one side of each fixing bracket 22, with a insert 23 welded to one end of each spring 20. A sliding hole 21 is provided on one side of each fixing bracket 22, through which the insert 23 passes. Multiple slots 13 are provided on one side of each fixing rod 25, with the insert 23 engaging with the slots 13. A second inclined surface 24 is provided on the upper surface of the insert 23. During the movement of the slide rod 7, the fixing brackets 22 move, which in turn move the insert 23. During this movement, the insert 23 first inserts into the lowermost slot 13. As the slide rod 7 continues to move... Therefore, under the action of the second inclined surface 24 on the insert 23, the fixing rod 25 will push the insert 23 to move in the sliding hole 21, causing the insert 23 to disengage from the slot 13 and stretch the tension spring 20. When the insert 23 moves to align with the next slot 13, the insert 23 will be inserted into the next slot 13 under the force of the tension spring 20. This cycle continues until the uppermost sliding rod 7 moves to the top of the guide groove 8. At this time, the insert 23 will be inserted into the uppermost slot 13. Since the bottom of the insert 23 is horizontal, it will lock and fix the sliding rod 7, thereby fixing the stretching of the fence and realizing automatic locking and fixing of the height of the fence. This makes it easier for workers to use the fence and improves the convenience of using the fence.

[0040] The blocking component includes two sliding openings 14, which are symmetrically opened on the outer circumference of the insert rod 12. A slider 15 is slidably connected in each of the two sliding openings 14. The bottom of the slider 15 is provided with a first inclined surface 17. A spring 16 is welded in each of the two sliding openings 14 and the spring 16 is fixed to the slider 15. An extension plate is integrally formed at the top of the insert rod 12. When the insert rod 12 is inserted, the first connecting ear 9 will push the slider 15 into the sliding opening 14 through the first inclined surface 17 of the slider 15. The slider 15 will squeeze the spring 16. When the slider 15 moves below the second connecting ear 11, the slider 15 will be reset by the force of the spring 16. Thus, the slider 15 and the extension plate cooperate to limit the insertion rod 12, so that the insertion rod 12 will not easily detach from the first connecting ear 9 and the second connecting ear 11, thereby improving the stability of the two fences assembly.

[0041] The working principle of this embodiment is as follows: During use, pulling the uppermost sliding rod 7 upwards along the guide groove 8 causes the cross arm 18 to rotate. Simultaneously, both ends of the cross arm 18 rotate with the sliding rod 7, while the other two ends of the cross arm 18 rotate with the connecting shaft, causing the connecting shaft to move along the slide groove 19. When the connecting shaft reaches the other end of the slide groove 19, the cross arm 18 stops rotating, and the sliding rod 7 continues to move upwards, thus pulling the lower sliding rod 7 upwards via the cross arm 18. This cycle repeats, thereby stretching the fence. During the stretching of the fence, due to the rotation of the other two ends of the cross arm 18... The end moves within the slide groove 19 via the connecting shaft, thus not narrowing the fence, thereby increasing the fence's protection range and saving costs. During its movement, the slide bar 7 drives the fixed frame 22, which in turn drives the insert bracket 23. The insert bracket 23 initially inserts into the lowest slot 13. As the slide bar 7 continues to move, the second inclined surface 24 on the insert bracket 23 causes the fixed rod 25 to push the insert bracket 23 within the slide hole 21, disengaging it from the slot 13 and stretching the tension spring 20. When the insert bracket 23 aligns with the next slot 13, it will... Under the force of the tension spring 20, it is inserted into the next slot 13, and so on, until the uppermost slide rod 7 moves to the top of the guide groove 8. At this time, the insert 23 will be inserted into the uppermost slot 13. Since the bottom of the insert 23 is horizontal, it will lock and fix the slide rod 7, thereby fixing the tension of the fence and realizing automatic locking and fixing of the fence height. This makes it easier for workers to use the fence and improves the convenience of fence use. When encountering a corner, the two fences are combined, and the first connecting ear 9 on one fence is aligned vertically with the second connecting ear 11 on the other fence. Then, the insert rod 12 is inserted. The rod 12 is inserted into the first connecting ear 9 and the second connecting ear 11, thereby connecting the two fences. This allows the fence assembly to bend and protect corners. When the rod 12 is inserted, the first connecting ear 9 pushes the slider 15 into the sliding opening 14 through the first inclined surface 17 of the slider 15. The slider 15 compresses the spring 16. When the slider 15 moves below the second connecting ear 11, it resets under the force of the spring 16. The cooperation between the slider 15 and the extension plate limits the rod 12, preventing it from easily detaching from the first connecting ear 9 and the second connecting ear 11, thus improving the stability of the assembled fences.
