Abstract
Description
Technical Field
[0001] This utility model relates to the field of guardrail technology, specifically to a prefabricated isolation guardrail. Background Technology
[0002] Guardrails are ubiquitous in our lives. Guardrails, specifically industrial "protective barriers," are primarily used in residential areas, highways, commercial zones, and public places to protect personal safety and equipment. Guardrails are made from various materials, resulting in diverse installation methods; prefabricated guardrails are one of the most common types.
[0003] Chinese patent document CN218712462U discloses a prefabricated isolation guardrail. Through the interlocking of bases, the folding guardrail slides between the bases, realizing the unfolding and storage of the folding guardrail. During transportation, the bases are stacked together, and the folding guardrail is in a stored state, reducing the floor space and facilitating transportation.
[0004] In the above solution, the folding guardrail is placed perpendicular to the base after being stored, and the folding guardrail can slide inside the base. This results in the folding guardrail taking up a lot of space when it is folded up, and the folding guardrail moves relative to the base during transportation, making it inconvenient to handle and transport. Utility Model Content
[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a prefabricated isolation guardrail.

[0009] There are two connecting components, which are respectively located at one end of the base and the top plate and connected to another base and the top plate.
[0010] Preferably, support plates are provided on both sides of both ends of the base.
[0011] Preferably, the end face projections of both the base and the top plate are U-shaped.

[0014] An internally threaded tube is positioned between two support rods and is threadedly connected to a two-way lead screw.
[0015] There are two connecting plates, which are respectively set at the top and bottom of the internally threaded tube and rotatably connected to the support rod through a third pin.
[0016] Preferably, one end of the bidirectional lead screw is provided with a connecting male end.
[0017] Preferably, the other end of the bidirectional lead screw is provided with a female connector, and the end face of the female connector is provided with a groove, the size of which is arranged to match the size of the male connector.

[0019] The plug-in plate is located on the inside of the top plate;
[0020] The second pin is located on the side of the plug plate and passes through the plug plate and connects to another top plate.
[0021] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0022] 1. This utility model uses a bidirectional lead screw to rotate in both directions, driving the support frame to unfold, thereby adjusting the distance between the base and the top plate to form a guardrail structure.

[0029] Example 1
[0030] like Figure 1-4 As shown, the present invention proposes a prefabricated isolation guardrail, which includes a base 1, a top plate 12, a bidirectional lead rod 4, and a connecting assembly.
[0031] The top plate 12 is positioned above the base 1 and arranged symmetrically with the base 1. Support frames are provided between both ends of the base 1 and the support plate 2 for adjusting the distance between the base 1 and the top plate 12 during use.
[0032] A bidirectional lead screw 4 is disposed between the base 1 and the top plate 12 and connected to two support frames. One end of the bidirectional lead screw 4 is provided with a male connector 11, which is used to connect the male connector 11 to the tool during use, making the rotation of the bidirectional lead screw 4 more convenient. The other end of the bidirectional lead screw 4 is provided with a female connector 10. The end face of the female connector 10 is provided with a groove. The size of the groove is arranged to match the size of the male connector 11. When the two bases 1 are connected, the female connector 10 is sleeved on the outside of the male connector 11, so that the two bidirectional lead screws 4 are connected to each other, and thus the two bidirectional lead screws 4 rotate synchronously, making it easier to adjust the distance between the multiple top plates 12 and the base 1.
[0033] There are two connecting components. The two connecting components are respectively set at one end of the base 1 and the top plate 12 and connected to another base 1 and top plate 12. They are used to connect adjacent base 1 and top plate 12 during use, so that multiple base 1 and multiple top plates 12 are connected into one piece, making the overall structure more stable and facilitating quick installation and disassembly.
[0034] In an optional embodiment, support plates 2 are provided on both sides of the base 1. The support plates 2 are used to increase the bottom area of the base 1 during use to improve the overall stability and prevent tipping during use. The support plates 2 are provided with mounting holes for fixing the base 1 to other fasteners or the ground with bolts, thereby effectively enhancing the overall stability of the guardrail.
[0035] In an optional embodiment, the end face projections of the base 1 and the top plate 12 are both U-shaped, and they are arranged facing each other through the U-shaped openings of the base 1 and the top plate 12, so that a receiving space is formed between the base 1 and the top plate 12 after storage, which is used to store the bidirectional lead screw 4 and the support frame, avoiding taking up too much space during transportation or storage, and also facilitating quick installation and disassembly on site.
[0036] In this embodiment, a connecting component is provided at one end of the base 1 and the top plate 12, enabling them to be quickly spliced with adjacent units. Simultaneously, the bidirectional lead screw 4 drives the connecting female head 10 to be sleeved on the outside of the connecting male head 11 at the end of the bidirectional lead screw 4 of the adjacent unit, realizing the rapid splicing and combination of multiple guardrails. The support plate 2 increases the bottom area of the base 1 on both sides, significantly improving the overall stability and effectively preventing tipping during use. During operation, the tool is connected to the connecting male head 11 at the end of the bidirectional lead screw 4. Rotating the bidirectional lead screw 4 will drive the two bidirectional lead screws 4 to rotate synchronously through the cooperation of the connecting female head 10 and the adjacent connecting male head 11. This allows the bidirectional lead screw 4 to drive multiple support frames to adjust synchronously, thereby raising the top plate 12. Finally, the base 1, the top plate 12, the bidirectional lead screw 4, and the support frames together form a guardrail structure. This structure can be quickly installed and disassembled, and the distance between the base 1 and the top plate 12 can be flexibly set through the coordinated adjustment of the bidirectional lead screw 4 and the support frames, making it suitable for various usage scenarios.
[0037] Example 2
[0038] like Figure 3 As shown, the present invention proposes a prefabricated isolation guardrail. Compared with the first embodiment, the difference in this embodiment is that the support frame includes a support rod 3, an internal threaded tube 5, a connecting plate 6, a first pin 7, and a third pin 13.
[0039] There are two support rods 3, and the two support rods 3 are rotatably connected to the base 1 and the top plate 12 respectively through the first pin 7;
[0040] The internally threaded tube 5 is positioned between the two support rods 3 and is threadedly connected to the bidirectional lead screw 4.
[0041] There are two connecting plates 6, which are respectively set at the top and bottom of the internal threaded tube 5 and rotatably connected to the support rod 3 through the third pin 13.
[0042] In this embodiment, two support rods 3 are rotatably installed on the inner sides of the base 1 and the top plate 12 respectively by the first pin 7, realizing the detachable connection between the support rods 3 and the base 1 and the top plate 12. Connecting plates 6 are set at the upper and lower ends of the internal threaded tube 5. The connecting plates 6 are rotatably and detachably connected to the support rods 3 by the third pin 13, so that the two sets of support rods 3 form a rotating pair between the base 1 and the connecting plate 6 and between the top plate 12 and the connecting plate 6 respectively. When the internal threaded tube 5 moves along the length direction of the bidirectional screw 4, the support rods 3 rotate between the connecting plate 6 and the base 1, pushing the internal threaded tube 5 and the bidirectional screw 4 to move upward. At the same time, the other set of support rods 3 rotates between the connecting plate 6 and the top plate 12, driving the top plate 12 to move upward synchronously, thereby accurately adjusting the distance between the base 1 and the top plate 12, and making the distance between the base 1 and the top plate 12 flexibly adjustable to adapt to different usage requirements.
[0043] Example 3
[0044] like Figure 1-3 As shown, the present invention proposes a prefabricated isolation guardrail. Compared with the first embodiment, the difference in this embodiment is that the connecting component includes a second pin 8 and a plug plate 9.
[0045] The plug-in plate 9 is located on the inner side of the top plate 12;
[0046] The second pin 8 is located on the side of the plug plate 9 and passes through the plug plate 9 and another top plate 12 to connect with it.
[0047] In this embodiment, a plug-in plate 9 is disposed on the inner side of the end of the top plate 12 or the base 1, and the plug-in plate 9 extends to the outer side of the base 1 or the top plate 12. When two bases 1 or top plates 12 are placed adjacent to each other, the plug-in plate 9 can be inserted into the inner side of the end of the adjacent base 1 or top plate 12, and the second pin 8 passes through the plug-in plate 9 and the adjacent base 1 or top plate 12, so that the two connecting males 11 or top plates 12 are fixedly connected to the plug-in plate 9 through the second pin 8, thereby realizing the quick connection and fixation of adjacent guardrail units.
[0048] In this invention, two sets of support rods 3 form rotating pairs between the base 1 and the connecting plate 6, and between the top plate 12 and the connecting plate 6, respectively. A tool drives a bidirectional lead screw 4 to rotate, causing the bidirectional lead screw 4 to move the internally threaded tube 5 along its length. Simultaneously, the two support rods 3 rotate between the connecting plate 6 and the base 1, and between the connecting plate 6 and the top plate 12, pushing the internally threaded tube 5 and the bidirectional lead screw 4 upwards. This also causes the top plate 12 to move upwards above the connecting plate 6, thereby precisely adjusting the distance between the base 1 and the top plate 12. The base 1, top plate 12, bidirectional lead screw 4, and support frame together form a guardrail structure. By reversing the rotation of the bidirectional lead screw 4, the internally threaded tube 5 is reset, which in turn causes the support rods 3 to rotate in the opposite direction, causing the top plate 12 and the internally threaded tube 5 to move downwards. During the process, the distance between the top plate 12 and the base 1 gradually decreases, and the support rod 3, the double-acting screw 4, the internal threaded tube 5, and the connecting plate 6 are stored between the base 1 and the top plate 12, realizing the rapid folding and storage of the guardrail structure, which is convenient for carrying and storage. At the same time, the plug plate 9 is inserted into the inner side of the end of the adjacent base 1 or top plate 12 before the support rod 3 rotates, and the second pin 8 passes through the plug plate 9 and the adjacent base 1 or top plate 12, so that the two connecting male heads 11 or the top plate 12 are fixedly connected to the plug plate 9 through the second pin 8. The double-acting screw 4 drives the connecting female head 10 to be sleeved on the outside of the connecting male head 11 at the end of the double-acting screw 4 of the adjacent unit, realizing the rapid splicing and combination of multiple guardrails, and allowing multiple guardrails to be unfolded or stored simultaneously, thereby significantly improving the convenience and flexibility of guardrail combination use.
[0049] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
