[0001] The utility model relates to the technical field of building construction, especially a building construction protective screen convenient to install. BACKGROUND

[0002] The building construction protective screen is mainly used for protecting construction personnel, equipment and pedestrians on the construction site, ensuring that the construction process is not disturbed or threatened by accidents, and preventing construction waste, objects and the like from falling, thereby ensuring the safety of the surrounding environment and pedestrians. The protective screen is widely used in construction sites, especially in high-rise buildings, bridges, tunnels and other engineering projects.

[0003] Most of the protective screens in the prior art are fixed on the construction frame in a knotting manner. This fixing manner easily causes the protective screen to slide along the construction frame, and the knotting fixing manner is uncertain, which causes the protective screen to fall off when impacted, has great safety hazards, and the protective screen after knotting is difficult to disassemble from the construction frame. UTILITY MODEL CONTENTS

[0004] The utility model solves the problem that the conventional protective screen is fixed on the construction frame in a knotting manner, which easily causes the protective screen to slide along the construction frame, and the knotting fixing manner is uncertain, which causes the protective screen to fall off when impacted, has great safety hazards, and the protective screen after knotting is difficult to disassemble from the construction frame, and therefore provides a building construction protective screen convenient to install.

[0005] The utility model adopts the following technical scheme: a building construction protective screen convenient to install, including receiving shell, the receiving shell inner wall rotation is connected with the rotation rod, the rotation rod top penetrates the receiving shell inner wall and extends, the rotation rod top is equipped with the adjusting groove, the rotation rod inner wall is fixedly connected with T type limit piece, T type limit piece is fixedly connected with the protective screen far from the one end of rotation rod, the protective screen top is fixedly connected with rubber guide block, rubber guide block outer wall is connected in the receiving shell inner wall sliding, the protective screen is fixedly connected with T type limit piece two far from T type limit piece one end, T type limit piece two outer wall contact is provided with protective screen fixed rod, the protective screen fixed rod inner wall rotation is connected with the central rod, the central rod outer wall rotation is connected with the limit piece, the protective screen fixed rod top is equipped with the guide groove, the limit piece top is equipped with adjusting groove two, adjusting groove two inner wall is connected with adjusting slide rod, adjusting slide rod outer wall is connected in the guide groove inner wall sliding, adjusting slide rod bottom is fixedly connected with the tension spring, the tension spring is fixedly connected in the limit piece inner wall far from adjusting slide rod one end, adjusting slide rod one end is fixedly connected with operating block far from the tension spring, operating block surface contact sets up in the protective screen fixed rod top.

[0006] As a further improvement to the above solution, two rubber guide blocks are provided, and the two rubber guide blocks are symmetrically arranged with the protective net as the center.

[0007] Through the above technical solution, the T-shaped limiting block 2 is pulled outward, the T-shaped limiting block 2 drives the protective net, and the protective net drives the rubber guide block to slide outward along the inner wall of the storage shell. At the same time, the protective net drives the T-shaped limiting block to make the rotating rod rotate. The design of the rubber guide block effectively prevents the protective net from folding when it is taken out and stored.

[0008] As a further improvement to the above solution, a limiting plate is slidably connected to the inner wall of the storage shell, and a protective net limiting block is fixedly connected to one end of the limiting plate near the protective net, with the outer wall of the protective net limiting block contacting and set against the inner wall of the protective net.

[0009] As a further improvement to the above solution, a limiting groove is provided on the inner wall of the protective net limiting block, and a limiting rod is slidably connected to the inner wall of the limiting groove. The end of the limiting rod away from the limiting plate is fixedly connected to a second limiting block.

[0010] As a further improvement to the above solution, the second limiting block is disposed in contact with the surface of the protective net, and a spring is disposed in contact with the outer wall of the limiting rod, with the end of the spring away from the limiting plate fixedly connected to the inner wall of the limiting groove.

[0011] As a further improvement to the above solution, the inner wall of the protective net limiting block is provided with an adjustment groove three, the outer wall of the limiting block two is slidably connected to the inner wall of the adjustment groove three, and the end of the protective net limiting block near the limiting plate is provided with an adjustment groove four.

[0012] As a further improvement to the above solution, several protective net limiting blocks, several limiting rods, several limiting blocks, and several springs are provided.

[0013] With the above technical solution, after the protective net is fixed, the limiting plate is installed on the surface of the housing shell. The limiting plate drives the limiting block of the protective net to engage in the mesh hole inside the protective net. Then, by pressing the adjusting groove four opened by the limiting rod inward, the limiting rod moves along the limiting groove towards the protective net. At the same time, the limiting rod drives the limiting block two, causing the limiting block two to disengage from the adjusting groove three.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention involves pulling the T-shaped limiting block two outwards. The T-shaped limiting block two moves the protective net, which in turn moves the rubber guide block outwards along the inner wall of the storage shell. Simultaneously, the protective net moves the T-shaped limiting block, causing the rotating rod to rotate. The design of the rubber guide block effectively prevents the protective net from folding during removal and storage. Then, the T-shaped limiting block two is installed inside the protective net fixing rod. Next, the operating block is pulled upwards. The operating block moves the adjusting slide rod upwards along the adjusting groove two opened in the limiting block. At the same time, the adjusting slide rod pulls the tension spring upwards, and then the operating block moves the adjusting... The sliding rod slides along the guide groove at the top of the protective net fixing rod. Adjusting the sliding rod drives the limiting block, which rotates 90 degrees around the central rod, so that the surface of the limiting block limits the T-shaped limiting block two, preventing the protective net from detaching from the protective net fixing rod during use. Then, the operating block is released, and the adjusting sliding rod at the bottom of the operating block moves downward under the tension of the tension spring, so that the adjusting sliding rod is locked inside the guide groove, preventing the limiting block from rotating and maintaining the limiting relationship between the limiting block and the T-shaped limiting block two. This protective net is simple and convenient to install, automatically retracts, and is easy to disassemble.

[0016] This invention, after fixing the protective net, installs a limiting plate on the surface of the housing shell. The limiting plate causes the protective net limiting block to engage with the mesh holes inside the protective net. Then, by pressing inward through the adjustment groove four of the limiting rod, the limiting rod moves along the limiting groove towards the protective net. At the same time, the limiting rod drives the limiting block two, causing the limiting block two to disengage from the adjustment groove three. Then, by rotating the adjustment groove four of the limiting rod, the limiting rod drives the limiting block two to rotate 90 degrees. Finally, the limiting rod is released, and the spring pushes the limiting rod, causing the limiting block two to laterally contact the back of the protective net limiting block. This limits the protective net and prevents it from detaching outward due to impact when there is still a protective net inside the housing shell. Attached Figure Description

A central rod 9 is rotatably connected to the inner wall of the protective net fixing rod 8, and a limiting block 10 is rotatably connected to the outer wall of the central rod 9. A guide groove 11 is opened at the top of the protective net fixing rod 8, and an adjustment groove 12 is opened at the top of the limiting block 10. An adjustment slide rod 13 is slidably connected to the inner wall of the adjustment groove 12, and the outer wall of the adjustment slide rod 13 is slidably connected to the inner wall of the guide groove 11. A tension spring 14 is fixedly connected to the bottom of the adjustment slide rod 13, and the end of the tension spring 14 away from the adjustment slide rod 13 is fixedly connected to the inner wall of the limiting block 10. An operating block 15 is fixedly connected to the end of the adjustment slide rod 13 away from the tension spring 14, and the surface of the operating block 15 is in contact with the top of the protective net fixing rod 8.

[0033] There are two rubber guide blocks 6, which are symmetrically arranged with the protective net 5 as the center.

[0034] A limiting plate 16 is slidably connected to the inner wall of the outer casing 1. A protective net limiting block 17 is fixedly connected to one end of the limiting plate 16 near the protective net 5. The outer wall of the protective net limiting block 17 is in contact with the inner wall of the protective net 5.

[0035] A limiting groove 18 is provided on the inner wall of the protective net limiting block 17. A limiting rod 19 is slidably connected to the inner wall of the limiting groove 18. One end of the limiting rod 19 away from the limiting plate 16 is fixedly connected to a limiting block 20.

[0036] The surface of the limiting block 20 is in contact with the surface of the protective net 5, and the outer wall of the limiting rod 19 is in contact with the spring 21. The end of the spring 21 away from the limiting plate 16 is fixedly connected to the inner wall of the limiting groove 18.

[0037] The inner wall of the protective net limiting block 17 is provided with an adjustment groove 3 22, the outer wall of the limiting block 20 is slidably connected to the inner wall of the adjustment groove 3 22, and the end of the protective net limiting block 17 near the limiting plate 16 is provided with an adjustment groove 4 23.

[0038] The protective net limit block 17 is provided in several units, the limit rod 19 is provided in several units, the limit block 20 is provided in several units, and the spring 21 is provided in several units.

[0039] The implementation principle of a construction safety net that is easy to install in this embodiment is as follows: By pulling the T-shaped limiting block 7 outward, the T-shaped limiting block 7 drives the safety net 5, and the safety net 5 drives the rubber guide block 6 to slide outward along the inner wall of the housing 1. At the same time, the safety net 5 drives the T-shaped limiting block 4 to rotate the rotating rod 2. The design of the rubber guide block 6 effectively prevents the safety net 5 from folding when it is taken out and put away. Then, the T-shaped limiting block 7 is installed inside the safety net fixing rod 8. Then, the operating block 15 is pulled upward, and the operating block 15 drives the adjusting slide rod 13 along the adjusting groove opened in the limiting block 10. As the second 12 moves upward, the adjusting slide rod 13 pulls the tension spring 14 upward. Then, the operating block 15 drives the adjusting slide rod 13 to slide along the guide groove 11 at the top of the protective net fixing rod 8. The adjusting slide rod 13 drives the limiting block 10, which rotates 90 degrees around the center rod 9, so that the surface of the limiting block 10 limits the T-shaped limiting block 7, preventing the protective net 5 from detaching from the protective net fixing rod 8 during use. Then, the operating block 15 is released, and the adjusting slide rod 13 at the bottom of the operating block 15 moves downward under the tension of the tension spring 14, so that the adjusting slide rod 13 is locked in the guide groove 11. To prevent the limiting block 10 from rotating, the limiting block 10 maintains its limiting relationship with the T-shaped limiting block 7. This protective net is simple and convenient to install, automatically retracts, and is easy to disassemble. After fixing the protective net 5, the limiting plate 16 is installed on the surface of the storage shell 1. The limiting plate 16 drives the protective net limiting block 17 to engage in the mesh holes inside the protective net 5. Then, by pressing inward through the adjusting groove 23 opened in the limiting rod 19, the limiting rod 19 moves along the limiting groove 18 towards the protective net 5. At the same time, the limiting rod 19 drives the limiting block 20, causing the limiting block 20 to disengage from the adjusting groove 22. By rotating the limiting rod 19 through the adjustment groove 23, the limiting rod 19 drives the limiting block 20 to rotate 90 degrees. Then, the limiting rod 19 is released, and the spring 21 pushes the limiting rod 19, so that the limiting block 20 makes lateral contact with the back of the protective net limiting block 17. This limits the protective net 5, preventing it from detaching outward due to impact when there is a protective net 5 inside the housing shell 1, thus rendering the protective net 5 unable to provide protection. At the same time, the limiting block 20 limits the protective net 5, preventing the protective net limiting block 17 and the limiting plate 16 from detaching from the housing shell 1, thus providing a fixing function.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
