Description

Technical Field

[0001] This utility model relates to the field of construction safety equipment technology, specifically a protective net for construction projects. Background Technology

[0002] Safety nets are crucial safety facilities during construction. However, existing safety nets can only protect people or objects on the ground or objects falling from the air. They are difficult to adjust to different needs and require disassembly and reassembly to change the protective mode, which is cumbersome and inconvenient. Therefore, we propose a new type of safety net for construction projects. Utility Model Content

[0003] The purpose of this utility model is to provide a protective net for construction projects, which solves the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a protective net for construction engineering, comprising a support plate one, a support plate two, a protective frame one, and a protective frame two. A base is fixedly installed at the bottom end of both support plate one and support plate two. A fixed frame is fixedly installed between support plate one and support plate two near the top end. A rotating shaft is rotatably connected to the inner wall of the fixed frame near the front and rear sides via bearings, and one end of the rotating shaft movably passes through support plate two. One end of each of the protective frames one and two is fixedly sleeved on the outer wall of the two rotating shafts. A protective net is fixedly installed on the inner wall of both protective frames one and protective frame two. Limiting and fixing components are provided on one side of support plate two near the top and bottom ends.

[0005] Both the first and second protective frames have folding grooves near their bottom sides. A folding leg is hinged to one end of the inner wall of the folding groove. A support screw is threaded into the threaded groove at the bottom of the folding leg. A support block is fixedly installed at the bottom of the support screw.

[0006] Preferably, a magnetic plate is fixedly installed at the top of the inner wall of the folding groove, and the folding leg is made of iron. By setting the magnetic plate, the folding leg can be attracted and fixed in the folding groove, thereby facilitating the storage of the folding leg.

[0007] Preferably, the limiting and fixing assembly includes a U-shaped frame, a slot is provided at one end of the rotating shaft, the U-shaped frame is inserted into the slot, a limiting rod is fixedly installed on the outer side of the second support plate, a rod hole is provided on the U-shaped frame, the limiting rod moves through the rod hole, a baffle is fixedly installed at one end of the limiting rod, a spring is fixedly connected between the inner side of the baffle and the outer wall of the U-shaped frame, and the spring surrounds the outer wall of the limiting rod.

[0008] Preferably, the U-shaped card frame is adapted to the card slot, and the limiting rod is adapted to the rod hole. By setting the limiting rod, the U-shaped card frame and the spring can be limited, ensuring the stability of the U-shaped card frame and the spring during compression.

[0009] Preferably, reinforcing rods are fixedly installed on the inner walls of both the first and second protective frames. The reinforcing rods are located below the protective net. By setting the reinforcing rods, the protective net can be supported to a certain extent, preventing the protective net from breaking when it is impacted by a large object, and improving the protective strength of the protective net. The reinforcing rods are made of alloy steel.

[0010] Preferably, the bottom end of the base is provided with a toothed groove, and the number of the toothed grooves is several. By setting the toothed grooves, the friction between the base and the ground can be increased, thereby improving the support stability of the base.

[0011] This utility model provides a protective net for construction projects. This protective net for construction projects has the following beneficial effects:

[0012] (1) The construction engineering protective net can adjust the form of the protective net according to the needs. When it is necessary to protect people or objects on the ground, the first protective frame and the second protective frame can be folded into a vertical state. When it is necessary to protect foreign objects falling from the air, the first protective frame and the second protective frame can be rotated upward so that the first protective frame and the second protective frame are unfolded on the same horizontal plane. This can greatly improve the practicality of the protective net and solve the problem that the existing protective net can only protect people or objects on the ground or foreign objects falling from the air. It is difficult to adjust its protective form according to the needs. It is necessary to disassemble and reassemble the protective net to realize the protective form conversion. The operation is more complicated and the use is less convenient.

[0013] (2) The protective net of the building project can provide a certain support by setting up reinforcing rods, so as to prevent the protective net from breaking when it is impacted by large objects and improve the protective strength of the protective net. By setting up magnetic plates, the folding legs can be attracted and fixed in the folding groove, which makes it easy to store the folding legs. The structure is simple and the practicality is strong. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1-6As shown, this utility model provides a technical solution: a protective net for construction engineering, including a support plate 1, a support plate 2, a protective frame 4 and a protective frame 5. The bottom ends of the support plate 1 and the support plate 2 are both fixedly installed with bases 15. A fixed frame 3 is fixedly installed between the support plate 1 and the support plate 2 near the top. The inner wall of the fixed frame 3 is rotatably connected to the rotating shaft 7 near the front and rear sides by bearings, and one end of the rotating shaft 7 movably passes through the support plate 2. One end of the protective frame 4 and the protective frame 2 5 are respectively fixedly sleeved on the outer wall of the two rotating shafts 7. The inner walls of the protective frame 4 and the protective frame 2 5 are both fixedly installed with protective nets 6. Limiting and fixing components 8 are provided on one side of the support plate 2 near the top and bottom.

[0025] Both the bottom of the protective frame 4 and the protective frame 5 are provided with folding grooves 12 near both sides. A folding support leg 9 is hinged to one end of the inner wall of the folding groove 12. A support screw 10 is threadedly connected to the threaded groove at the bottom of the folding support leg 9. A support block 11 is fixedly installed at the bottom of the support screw 10.

[0026] Specifically, the above technical solution describes a construction safety net 6 that can be adjusted to two forms during use. When protection of people or objects on the ground is required, the first protective frame 4 and the second protective frame 5 can be folded vertically. Then, the limiting and fixing component 8 is used to limit and fix the first protective frame 4 and the second protective frame 5, allowing the safety net 6 on the first protective frame 4 and the second protective frame 5 to protect people or objects on the ground. When protection against falling objects is required, the first protective frame 4 and the second protective frame 5 can be rotated upwards, unfolding them to the same horizontal plane. The limiting and fixing component 8 is then used again to limit and fix the first protective frame 4 and the second protective frame 5. Then, the folding legs 9 in the folding grooves 12 on the first protective frame 4 and the second protective frame 5 are rotated out, making the folding legs 9 perpendicular to the first protective frame 4 and the second protective frame 5. Finally, the support block 11 is rotated, causing the support screw 10 to rotate, which in turn causes the support screw 10 to drive the support block 11. Moving downwards, the support block 11 eventually contacts the ground, thus providing some support for the first protective frame 4 and the second protective frame 5. At this point, the protective net 6 on the first protective frame 4 and the second protective frame 5 can protect against foreign objects falling from the air. Through the above structure, the protective net 6 can be adjusted in shape according to needs. When it is necessary to protect people or objects on the ground, the first protective frame 4 and the second protective frame 5 can be folded into a vertical state. When it is necessary to protect against foreign objects falling from the air, the first protective frame 4 and the second protective frame 5 can be rotated upwards, so that the first protective frame 4 and the second protective frame 2 are unfolded on the same horizontal plane. This can greatly improve the practicality of the protective net 6 and solve the problem that the existing protective net 6 can only protect people or objects on the ground or foreign objects falling from the air. It is difficult to adjust its protective shape according to needs, and it is necessary to disassemble and reassemble the protective net 6 to achieve the protective shape conversion. The operation is relatively cumbersome and inconvenient to use.

[0027] Furthermore, a magnetic plate 13 is fixedly installed at the top of the inner wall of the folding groove 12, and the folding leg 9 is made of iron.

[0028] The magnetic plate 13 allows the folding leg 9 to be attracted and fixed in the folding groove 12, making it easier to store the folding leg 9.

[0029] Furthermore, the limiting and fixing assembly 8 includes a U-shaped frame 801, a slot 802 is provided at one end of the rotating shaft 7, the U-shaped frame 801 is inserted into the slot 802, a limiting rod 803 is fixedly installed on the outer side of the support plate 2, a rod hole 806 is provided on the U-shaped frame 801, the limiting rod 803 moves through the rod hole 806, a baffle 804 is fixedly installed at one end of the limiting rod 803, a spring 805 is fixedly connected between the inner side of the baffle 804 and the outer wall of the U-shaped frame 801, and the spring 805 surrounds the outer wall of the limiting rod 803;

[0030] By pulling the U-shaped frame 801 outward, the U-shaped frame 801 compresses the spring 805, causing the U-shaped frame 801 to disengage from the slot 802. At this point, the U-shaped frame 801 no longer limits the rotation shaft 7, and the protective frame 1 4 and the protective frame 2 5 can then rotate. After the positions of the protective frame 1 4 and the protective frame 2 5 are adjusted, the U-shaped frame 801 can be released. At this point, the U-shaped frame 801 will be inserted into the slot 802 under the reset force of the spring 805, thereby limiting the rotation shaft 7 again, and thus completing the fixation of the protective frame 1 4 and the protective frame 2 5. A slot 802 is also provided on one side of the protective frame 1 4 and the protective frame 2 5 near the bottom.

[0031] Furthermore, the U-shaped card frame 801 is adapted to the card slot 802, and the limiting rod 803 is adapted to the rod hole 806;

[0032] The limiting rod 803 can limit the movement of the U-shaped frame 801 and the spring 805, ensuring their stability during compression.

[0033] Furthermore, reinforcing rods 14 are fixedly installed on the inner walls of both protective frame 4 and protective frame 5, and the reinforcing rods 14 are located below the protective net 6.

[0034] The reinforcing rod 14 provides support for the protective net 6, preventing it from breaking when impacted by a large object and improving its protective strength.

[0035] Furthermore, the bottom end of the base 15 is provided with a toothed groove 16, and the number of toothed grooves 16 is several;

[0036] By setting the toothed groove 16, the friction between the base 15 and the ground can be increased, thereby improving the support stability of the base 15.
