Technical Field
[0001] This utility model belongs to the field of building construction technology, specifically relating to a flip-up mesh type tool-based protective fence. Background Technology
[0002] During building construction, there are numerous edges and openings, such as elevator entrances and floor perimeters. To prevent falls from heights or falling materials, safety protection measures are typically implemented at these areas. With increasing emphasis on standardized safety and civilized construction practices, standardized modular protective fences are commonly used at elevator entrances, floor perimeters, and other edges and openings. The minimum height requirement for floor perimeter edges is 1.2 meters, and for elevator entrances, it's at least 1.5 meters. However, these currently standardized modular protective fences are insufficient to meet the safety requirements of different usage scenarios. Utility Model Content
[0003] In view of the shortcomings of the existing technology, this utility model provides a flip-up mesh type tool-based protective fence, which can adjust the height of the protective fence to adapt to the safety protection needs of different heights in different usage scenarios.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a flip-up mesh type tool-based protective fence, including an inner post, an outer post, an inner protective fence, an outer protective fence, a rotating shaft, and an adjusting screw; The inner column is slidably sleeved on the inner side of the outer column. The outer column has an adjustment through hole on its side wall and an adjustment screw hole on its side wall. The adjustment screw passes through the adjustment through hole and is screwed into the adjustment screw hole. An outer connecting plate is provided on the side wall of the outer column, and the outer guardrail is connected to the outer connecting plate by bolts. The top of the inner guardrail is hinged to the top of the outer guardrail by a rotating shaft. An inner connecting plate is provided on the side wall of the inner column, and the inner connecting plate is used to connect to the inner guardrail by bolts.
[0005] Preferably, a toe plate is provided on the side wall of the outer column, and the toe plate is located below the outer guardrail.
[0006] Preferably, the top of the toe guard plate abuts against the bottom of the outer guardrail.
[0007] Preferably, the outer guardrail includes an outer guardrail frame and an outer steel mesh disposed inside the outer guardrail frame, wherein the outer guardrail frame and the outer connecting plate are connected by bolts.
[0008] Preferably, the outer protective fence frame and the outer steel mesh are integrally formed.
[0009] Preferably, the inner guardrail includes an inner guardrail frame and an inner steel mesh disposed inside the inner guardrail frame.
[0010] Preferably, the inner protective railing frame is integrally formed with the inner steel mesh.
[0011] Preferably, the rotating shaft is equipped with a ratchet mechanism.
[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a flip-up mesh-type modular protective fence. When the protection height requirement is low, it can be used directly. When the protection height requirement is high, the inner protective fence is flipped upwards to a vertical position, and then the inner post is pulled out and bolted to the inner protective fence to fix it in place. In other words, by configuring two protective fence panels, which are hinged together by a rotating shaft, it can adapt to different usage scenarios with different protection height requirements. It has a high turnover rate; the overall components are modular, allowing for quick assembly or disassembly and reuse.
[0013] 2. The present invention provides a flip-up mesh type tool-based protective fence, wherein the ratchet mechanism can play a role in stopping the backflow and preventing the inner protective fence from suddenly falling during the upward flipping process, thus preventing accidents.

[0016] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0017] In order to enable tool-type protective fences to meet the safety protection requirements of various usage scenarios, this embodiment optimizes and transforms the existing mesh-type tool-type protective fences to provide a flip-up mesh-type tool-type protective fence, which can adapt to different protection height requirements by adjusting the height of the protective fence.
[0018] Specifically, the protective fence includes inner post 1, outer post 2, inner protective railing 3, outer protective railing 4, rotating shaft 5, and adjusting screw 9.
[0019] The inner column 1 is slidably sleeved on the inner side of the outer column 2. The outer column 2 has an adjustment through hole on its side wall and the inner column 1 has an adjustment screw hole on its side wall. The adjustment screw 9 passes through the adjustment through hole and is screwed into the adjustment screw hole. For example, see Figure 1-2 The outer column 2 is fixed to the ground, and the two outer columns 2 are arranged vertically at intervals. The outer column 2 is a sleeve structure with an open top, and the inner column 1 is slidably fitted on the inner side of the outer column 2 along the vertical direction.
[0020] For example, the outer column 2 has two adjusting through holes on its side wall, arranged vertically at intervals, corresponding to two adjusting screws 9. Meanwhile, the inner column 1 has four adjusting screw holes on its side wall, arranged in pairs, for a total of two sets. By sliding the inner column 1 up and down, the two adjusting screw holes in the same group of the inner column 1 are aligned with the two adjusting through holes of the outer column 2. Then, the adjusting screws 9 are passed through the adjusting through holes and screwed into the aligned adjusting screw holes, thus locking and fixing the inner column 1 and the outer column 2. The two sets of adjusting screw holes on the side wall of the inner column 1 are arranged vertically at intervals.
[0021] An outer connecting plate 6 is provided on the side wall of the outer column 2. The outer guardrail 4 is connected to the outer connecting plate 6 by bolts. The top of the inner guardrail 3 is hinged to the top of the outer guardrail 4 by a rotating shaft 5. An inner connecting plate 7 is provided on the side wall of the inner column 1. The inner connecting plate 7 is used to connect to the inner guardrail 3 by bolts. For example, see Figure 1-2 Two external connecting plates 6 are fixedly installed on the side wall of the outer column 2. The two external connecting plates 6 are arranged vertically at intervals, and the external connecting plates 6 are provided with connecting screw holes.
[0022] For example, the outer guardrail 4 is installed between two outer posts 2, and is arranged vertically. The outer guardrail 4 has two connecting through holes on its left side, which are aligned with the connecting screw holes of the two outer connecting plates 6 of the left outer post 2. The outer guardrail 4 also has two connecting through holes on its right side, which are aligned with the connecting screw holes of the two outer connecting plates 6 of the right outer post 2. Then, by screwing bolts through the connecting through holes of the outer guardrail 4 and into the aligned connecting screw holes of the outer connecting plates 6, the outer guardrail 4 can be fixed to the outer post 2.
[0023] For example, a bracket is fixed to the top of the outer guardrail 4, and a rotating shaft 5 is rotatably mounted on the bracket. The inner guardrail 3 is positioned between the two outer posts 2, and its top is fixed to the rotating shaft 5, allowing the inner guardrail 3 to rotate around the rotating shaft 5. Figure 3-4 As shown.
[0024] For example, see Figure 1-2 An inner connecting plate 7 is fixedly installed on the side wall of the inner column 1, and the inner connecting plate 7 is also provided with connecting screw holes.
[0025] For example, the inner guardrail 3 has a connecting through hole on each of its left and right sides. Flip the inner guardrail 3 upwards to a vertical position, then remove the adjusting screw 9 and slide the inner column 1 upwards until the connecting screw hole of the inner connecting plate 7 of the inner column 1 aligns with the connecting through hole of the inner guardrail 3. Furthermore, the connecting through holes on the left and right sides of the inner guardrail 3 should be aligned with the connecting screw holes of the inner connecting plates 7 of the inner columns 1 on both sides. Finally, bolts are passed through the connecting through holes of the inner guardrail 3 and screwed into the aligned connecting screw holes of the inner connecting plates 7 to secure the inner guardrail 3.
[0026] It should be noted that there are four adjusting screw holes on the side wall of the inner column 1, in two groups of two, for a total of two groups. When the inner column 1 slides upward until the connecting screw hole of the inner connecting plate 7 of the inner column 1 is aligned with the connecting through hole of the inner guardrail 3, at this time, the group of adjusting screw holes on the side wall of the inner column 1 near the bottom is aligned with the two adjusting through holes on the side wall of the outer column 2. The adjusting screw 9 can be passed through the corresponding adjusting through hole and screwed into the aligned adjusting screw hole to lock and fix the inner column 1 and the outer column 2 again.
[0027] When it is not necessary to flip the inner guardrail 3 upwards, the set of adjusting screw holes on the side wall of the inner post 1 near the top can be aligned with the two adjusting through holes on the side wall of the outer post 2. Then, the adjusting screw 9 is passed through the corresponding adjusting through hole and screwed into the aligned adjusting screw hole to lock the inner post 1 and the outer post 2 in place, preventing the inner post 1 from sliding back and forth.
[0028] Based on the above structure, the protective fence provided in this embodiment can be used directly when the protection height requirement is low. When the protection height requirement is high, the inner protective fence 3 can be fixed by flipping the inner protective fence 3 upwards to a vertical position, then pulling out the inner post 1, and connecting the inner post 1 to the inner protective fence 3 with bolts. In other words, by configuring two protective fences that are hinged together, it can adapt to different usage scenarios with different protection height requirements. It has a high turnover rate; the overall components are modular, allowing for quick assembly or disassembly and reuse.
[0029] Since there are two requirements for the height of the edge protection railings commonly used on construction sites, namely 1.2 meters and 1.5 meters, it is recommended that the height be controlled within 1.2 meters before being overturned and within 1.5 meters after being overturned, in order to save money.
[0030] The outer connecting plate 6 can have a connecting screw hole on each of its left and right sides, so that outer guardrails 4 can be installed on both the left and right sides of the outer column 2. For example, three outer columns 2 are arranged at intervals, so two outer guardrails 4 can be installed between the three outer columns 2, and the outer connecting plate 6 of the middle outer column 2 can be connected to the two outer guardrails 4 respectively by bolts.
[0031] Similarly, each of the left and right sides of the inner connecting plate 7 can be provided with a connecting screw hole, and the inner connecting plate 7 of the inner column 1 in the middle can be connected to the two inner guardrails 3 by bolts.
[0032] Secondly, the inner connecting plate 7 can also prevent the inner column 1 from sliding completely into the outer column 2 due to gravity, making operation more convenient.
[0033] Based on the above technical solution, in the technical solution provided in this embodiment, a toe board 8 is provided on the side wall of the outer column 2, and the toe board 8 is located below the outer guardrail 4; The top end of the toe board 8 abuts against the bottom end of the outer guardrail 4; For example, referring to Figure 1-2 , the toe board 8 is arranged between two outer columns 2, and the toe board 8 can be connected to the outer column 2 by bolts. The top end of the toe board 8 abuts against the bottom end of the outer guardrail 4, and the bottom end of the toe board 8 is connected to the ground. The setting of the toe board 8 can prevent a gap from existing between the outer guardrail 4 and the ground, so that objects can fall from the gap, resulting in accidents.
[0034] In the technical solution provided in this embodiment, the outer guardrail 4 includes an outer guardrail frame and an outer steel wire mesh arranged inside the outer guardrail frame. The outer guardrail frame is connected to the outer connecting plate 6 by bolts; the outer guardrail frame and the outer steel wire mesh are integrally formed; For example, referring to Figure 2 , the outer guardrail frame is in a cross shape structure, that is, the outer guardrail frame has four windows, and outer steel wire meshes are arranged in all four windows. The outer steel wire mesh is in a mesh structure, which is convenient for observing the situation on the opposite side. The outer guardrail frame and the outer steel wire mesh are integrally formed, with stable structure and high strength. Connecting through holes are provided on the outer guardrail frame for connecting to the outer connecting plate 6 by bolts.
[0035] In the technical solution provided in this embodiment, the inner guardrail 3 includes an inner guardrail frame and an inner steel wire mesh arranged inside the inner guardrail frame; the inner guardrail frame and the inner steel wire mesh are integrally formed; For example, referring to Figure 2 , the inner guardrail frame is in a rectangle shape structure, that is, the inner guardrail frame has two windows, and inner steel wire meshes are arranged in both windows. The inner steel wire mesh is in a mesh structure, which is convenient for observing the situation on the opposite side. The inner guardrail frame and the inner steel wire mesh are integrally formed, with stable structure and high strength. Connecting through holes are provided on the inner guardrail frame for connecting to the inner connecting plate 7 by bolts.
[0036] In the technical solution provided in this embodiment, the rotating shaft 5 is provided with a ratchet mechanism; Among them, the ratchet mechanism is a prior art, a kind of unidirectional intermittent motion mechanism composed of a ratchet 10 and a pawl 11. For example, referring to Figure 5 , the ratchet 10 is coaxially fixed with the rotating shaft 5. Due to the setting of the pawl 11, the ratchet 10 can only rotate counterclockwise, and the rotating shaft 5 can also only rotate counterclockwise, that is, the inner guardrail 3 can only swing upward counterclockwise, which can prevent the inner guardrail 3 from suddenly falling during the upward flipping process, resulting in accidents. On the contrary, when it is necessary to lower the inner guardrail 3, the pawl 11 can be manually拨开 (it should be "pried open" in English), so that the pawl 11 is disengaged from the ratchet 10, and then the inner guardrail 3 can be freely lowered.
