Technical Field

[0001] The present invention is a protection device for edge and hole openings without punching, belonging to the field of construction tools. Background Art

[0002] The protection of edge and hole openings is widely used in the field of construction. The current protection usually uses square steel pipes, which are directly nailed to the wall with bolts. Although it has the advantages of convenience and speed, since it needs to be fixed to the wall with bolts, it will damage the wall, and the wall needs to be repaired later, increasing the construction period and cost. Moreover, after the square steel pipe is fixed multiple times, the pipe body is damaged and cannot be used multiple times. In actual construction sites, the sizes and types of edge and hole openings are different. Using this new type of edge and hole opening protection system without punching can avoid punching holes in the wall or floor. The components of the protection system are convenient to install and disassemble, and the entire protection system has high reusability, saving the construction period and materials.

Detailed implementation manners

[0017] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0018] Please refer to Figures 1-7 , the present invention provides a technical solution for a hole-edge protection device without punching: including: Refer to Figure 3 , a fixing component 1, including a first clamping plate 11, a second clamping plate 12, and a limiting structure. In one embodiment, the first clamping plate 11 and the second clamping plate 12 clamp the two sides of the edge of the hole P inside the hole P, and the limiting structure acts on the second clamping plate 12 to form a firm fixation with the first clamping plate 11.

[0019] Preferably, the limiting structure includes: A base 13: The first clamping plate 11 is fixed to one side of the base 13.

[0020] An adjusting rod 14: Inserted into the base 13 and passing through the second clamping plate 12, having a hexagonal prism structure, with limiting pads at both ends (for preventing the second clamping plate 12 from slipping out of the adjusting rod 14), and equidistantly arranged grooves 17 on the upper top surface.

[0021] A tightening screw 15: Threadedly connected to the base 13, acting on the adjusting rod 14. By rotating the tightening screw 15, the connection between the first clamping plate 11 and the second clamping plate 12 can be fixed, and the teeth 16 inside the base 13 are pressed to insert into the grooves 17 of the adjusting rod 14 to achieve fixation. Preferably, the tightening screw 15 is used as the component to push the teeth 16, enabling workers to quickly complete the clamping of the hole P through an existing electric screwdriver.

[0022] Among them, the adjusting rod 14 is designed in a hexagonal prism shape. Firstly, it can prevent the inserted second clamping plate 12 from rotating under force, thus causing the second clamping plate 12 to become disconnected from the hole P. Secondly, the upper top surface of the adjusting rod 14 always faces the base 13, so that the teeth 16 can correspond to the grooves 17. Further, the front and rear side walls of the grooves 17 are in an inclined shape. When sliding the adjusting rod 14, this inclined surface can lift the teeth 16 to prevent the teeth 16 from jamming the adjusting rod 14 during the adjustment process.

[0023] Relying on the design of the adjustment rod 14 and the base 13, the application range of the device is greatly improved to adjust the edges of the openings P of different thicknesses.

[0024] See Figure 5 The telescopic component 2 includes an inner rod 21, an outer arm 22, and a positioning structure. There are at least two telescopic components 2, which are located in the hole P, with a fixed component 1 at each end to adapt to different heights of the hole P through telescopic adjustment. Inner rod 21: Slidingly mounted inside outer arm 22, with a tooth row 23 on one side.

[0025] See Figure 6 The positioning structure includes a clamping shaft 24 and a spring 25. The spring 25 acts on the clamping shaft 24 to engage the tooth row 23, thereby securing the inner rod 21 to the outer arm 22. By pulling the clamping shaft 24 outward, the clamping shaft 24 disengages the tooth row 23, thereby pulling the outer arm 22 to adjust to a suitable height. After the clamping shaft 24 is released, the spring 25 acts on the clamping shaft 24 to engage the tooth row 23, thereby securing the inner rod 21 to the outer arm 22.

[0026] See Figure 4 、 7 The protective net assembly 3 includes a plurality of horizontal frames 31 and a plurality of protective nets 32. The protective net assembly 3 is installed on the fixed assembly 1 to block the hole P to prevent people or objects from falling. Cross frame 31 : A long slot 33 is provided on the cross frame 31 . The cross frame 31 is placed on the base 13 . The tightening screw 15 passes through the long slot 33 , which facilitates adjustment of the position of the cross frame 31 on the base 13 .

[0027] The protective net 32 is composed of a number of equally spaced chains, both ends of which are fixedly connected to adjacent cross frames 31. Based on the chains, two adjacent cross sections are flexibly connected, which ensures both protective effect and flexibility.

[0028] A construction method for a punch-free edge opening P protection device comprises the following steps: Step 1: Visually inspect the size, shape and edge of the hole P to determine the approximate shape of the hole P, and make a judgment based on the maximum extension height and the minimum contraction height of the telescopic component 2 of this device; that is, if the left and / or right half of the hole P gradually shrinks, adjust the telescopic component 2 to the lowest height, and then press against the edge of the hole P; if the left and / or right half of the hole P gradually expands, adjust the telescopic component 2 to the corresponding height, and then press against the edge of the hole P.

[0029] Step 2: Place the first clamping plate 11 closely against the inner edge of the opening P. Pull the adjusting rod 14 outward to make the second clamping plate 12 move closer to the first clamping plate 11, and perform a clamping action on the edge of the opening P. It should be noted that at this time, the cross frame 31 needs to be placed on the base 13 in advance, and then use an electric screwdriver to rotate the tightening screw 15. The tightening screw 15 pushes the locking teeth 16, so that the locking teeth 16 are inserted into the groove 17 of the adjusting rod 14 to achieve the effect of fixing the adjusting rod 14, and the cross frame 31 is also fixed during the rotation of the tightening screw 15. Preferably, the cross frame 31 is placed on the lower base 13 in advance, and the placement position of the cross frame 31 needs to cover the entire diameter width of the opening P.

[0030] Step 3: Repeat Step 2 to adjust the telescopic assembly 2 and the fixing assembly 1 of the other half.

[0031] Step 4: Pull the adjusting rod 14 in the fixing assembly 1 of the upper half to make the second clamping plate 12 move closer to the first clamping plate 11, and perform a clamping action on the edge of the opening P. Then place the cross frame 31 corresponding to the base 13, and finally screw on the tightening screw 15.
