Description

Technical Field

[0001] This utility model belongs to the field of protective netting technology, and in particular relates to a protective netting panel with anti-tipping function. Background Technology

[0002] Construction safety nets are temporary barriers used at construction sites. Installing safety nets at construction sites serves as a safety warning and separation mechanism, ensuring smooth construction and the safety of construction workers. To a certain extent, they can prevent accidents caused by construction, thus gaining acceptance among engineering personnel. Due to their customizable production, convenient installation, and recyclability, safety nets are widely used in the construction industry and are an essential safety measure. Their numerous advantages and features have earned them widespread favor and trust from users.

[0003] Chinese Patent Publication No. CN 219298846 U discloses a protective net with an anti-tipping structure, including a first column. A top plate is fixedly connected to the upper end of one side of the first column, and the other end of the top plate is fixedly connected to the upper end of one side of the second column. A base plate is fixedly connected to the lower end of one side of the second column. The top of the base plate is fixedly connected to one end of the protective net, and the other end of the protective net is fixedly connected to the bottom of the top plate. An anti-tipping mechanism is provided inside the first column. The anti-tipping mechanism includes a motor. The bottom of the motor is fixedly attached to the bottom of the inner wall of the first column. The output end of the motor is fixedly connected to one end of a first screw. The other end of the first screw is rotatably connected to the top of the inner wall of the first column. The outer wall of the first screw is fixedly connected to the inner wall of a drive wheel. By providing the anti-tipping mechanism, the net is prevented from tipping over and endangering pedestrian safety.

[0004] The aforementioned patent includes an anti-tipping mechanism that allows for manual control of the structure's operation under adverse weather conditions. Multiple protective rods on both sides form a support structure to prevent the mesh from tipping over. However, this anti-tipping mechanism requires a motor for operation, and motors are generally heavy, significantly increasing the overall weight of the protective netting. Furthermore, the anti-tipping mechanism needs to be deployed and retracted under manual control, and construction site safety netting is typically quite long, greatly increasing the workload for workers. Utility Model Content

[0005] This utility model provides a protective mesh panel with anti-tipping function, which aims to solve the problems of the above-mentioned patent having a large overall weight and being inconvenient in actual use.

[0006] This utility model is implemented as follows: a protective mesh panel with anti-tipping function includes two vertically arranged support column mechanisms and a mesh panel vertically arranged between the two support column mechanisms;

[0007] Both of the support column mechanisms have the same structure. One of the support column mechanisms includes a vertically arranged column with a through hole at the top. A rotating column is vertically rotatably connected to the upper end of the through hole. A threaded hole is vertically opened at the bottom end of the rotating column. A threaded column is vertically threaded inside the threaded hole. A positioning pin is vertically fixedly connected to the bottom end of the threaded column and slidably connected inside the through hole.

[0008] Preferably, a plurality of limiting strips are vertically fixedly connected to the bottom end inside the through hole, and a plurality of limiting grooves corresponding to and adapted to the plurality of limiting strips are opened on the outer surface of the positioning pin.

[0009] Preferably, a crossbar is horizontally fixedly connected to the top and bottom of the two columns, and the mesh panel is fixedly connected between the two crossbars.

[0010] Preferably, a rectangular device groove is vertically formed at the top of the rotating column, a sliding seat is vertically slidably connected inside the device groove, a torsion bar is hinged to the top of the sliding seat, a limit piece is fixedly connected to the upper part of the outer surface of the torsion bar, and a pull ring is provided at the top of the torsion bar.

[0011] Preferably, a supporting outer ring is horizontally fixedly connected to the bottom end of the outer surface of the column.

[0012] Preferably, an extension support plate is horizontally fixedly connected to the rear surface of the outer support ring, and a diagonal brace is fixedly connected between the upper surface of the extension support plate and the rear surface of the column. Screw holes are vertically opened through the upper surfaces of both the outer support ring and the extension support plate.

[0013] Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a protective netting panel with an anti-tipping function. This anti-tipping protective netting panel, through the setting of a support column mechanism, includes a column. The bottom of the column has a positioning pin that can slide along its length. By rotating the column, the threaded hole inside drives the threaded pin to move along its length, thus driving the positioning pin, which is fixedly connected to the threaded pin, to move synchronously. This allows the positioning pin to be inserted into the ground, supporting the column. The combined action of multiple support column mechanisms improves the anti-tipping capability of the device. Its structure does not require a motor, and subsequent manual operation is unnecessary, ensuring overall weight while avoiding additional workload for workers. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a protective net panel with anti-tipping function, including two vertically arranged support column mechanisms and a net panel 13 vertically arranged between the two support column mechanisms;

[0021] The two support column mechanisms have the same structure. One of the support column mechanisms includes a vertically arranged column 1. The top of the column 1 has a through hole 2. The upper end of the through hole 2 is vertically rotatably connected to a rotating column 3. The bottom end of the rotating column 3 has a vertically opened threaded hole 4. The inside of the threaded hole 4 is vertically threaded to a threaded column 5. The bottom end of the threaded column 5 is vertically fixed to a positioning pin 6 that is vertically slidably connected inside the through hole 2.

[0022] In this embodiment, the support column mechanism of the device includes a column 1. The bottom of the column 1 is provided with a positioning pin 6 that can slide along its length. By rotating the column 3, the threaded pin 5 can be driven to move along its length under the action of the threaded hole 4 inside the column 1. This can also drive the positioning pin 6, which is fixedly connected to the threaded pin 5, to move synchronously. In this way, the positioning pin 6 can be inserted into the ground and the column 1 is supported by the positioning pin 6. The anti-tipping ability of the device is improved by the combined action of multiple support column mechanisms. Its structure does not require a motor to drive it, and no manual operation is required afterward. It ensures the overall weight and does not cause additional labor burden to the workers.

[0023] Furthermore, multiple limiting strips 7 are vertically fixedly connected to the bottom of the through hole 2, and multiple limiting grooves corresponding to and adapted to the multiple limiting strips 7 are opened on the outer surface of the positioning pin 6.

[0024] In this embodiment, the limiting strip 7 and the limiting groove cooperate to limit the positioning pin 6, preventing it from rotating. This also limits the threaded pin 5, preventing it from rotating synchronously with the rotating pin 3.

[0025] Furthermore, horizontal bars 12 are fixedly connected to the top and bottom of the two columns 1, and the mesh panel 13 is fixedly connected between the two horizontal bars 12.

[0026] In this embodiment, both crossbars 12 are made of aluminum alloy, which is lightweight and has stable structural strength, making them suitable for use as supports for the mesh panel 13.

[0027] Furthermore, a rectangular device groove 14 is vertically opened at the top of the rotating column 3. A sliding seat 15 is vertically slidably connected inside the device groove 14. A torsion bar 16 is hinged to the top of the sliding seat 15. A limit piece 17 is fixedly connected to the upper part of the outer surface of the torsion bar 16. A pull ring 18 is provided at the top of the torsion bar 16.

[0028] In this embodiment, when it is necessary to rotate the rotating column 3, pull the pull ring 18 to pull the torsion bar 16 outward until the top of the sliding seat 15 protrudes from the device groove 14. Then, the torsion bar 16 can be bent downward to a horizontal state and held to drive the rotating column 3 to rotate, thereby driving the rotating column 3 to rotate.

[0029] The limiting piece 17 on the outer surface of the torsion bar 16 can prevent the entire torsion bar 16 from falling into the device slot 14.

[0030] Furthermore, a supporting outer ring 8 is horizontally fixedly connected to the bottom end of the outer surface of the column 1.

[0031] An extension support plate 9 is horizontally fixedly connected to the rear surface of the outer ring 8. An inclined brace plate 10 is fixedly connected between the upper surface of the extension support plate 9 and the rear surface of the column 1. Screw holes 11 are vertically opened through the upper surfaces of both the outer ring 8 and the extension support plate 9.

[0032] In this embodiment, both the outer support ring 8 and the extended support plate 9 are fixed to the ground with screws to improve the stability of the column. At the same time, the extended support plate 9 and the diagonal brace 10 can provide the column 1 with a certain backward anti-tipping ability, thereby improving the overall stability of the device.

[0033] The working principle and usage process of this utility model are as follows: After installation, the support column mechanism of this utility model includes a column 1. The bottom of the column 1 is provided with a positioning pin 6 that can slide along its length. By rotating the column 3, the threaded pin 5 can be driven to move along its length under the action of the threaded hole 4 inside, which can also drive the positioning pin 6, which is fixedly connected to the threaded pin 5, to move synchronously. In this way, the positioning pin 6 can be inserted into the ground and supported by the positioning pin 6. With the joint action of multiple support column mechanisms, the anti-tipping ability of the device is improved. Its structure does not require a motor to drive it, and no manual operation is required afterward. It ensures the overall weight and does not cause additional labor burden to the workers.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
