Description

Technical Field

[0001] This utility model belongs to the technical field of steel grating, specifically relating to a quick fixing device for steel grating. Background Technology

[0002] Steel grating, also known as steel grid, is a steel product made by arranging flat steel bars at certain intervals and crossbars and welding them together to form square grids in the middle. It is mainly used as drainage ditch covers, steel structure platform panels, and steel stair treads. The crossbars are generally made of twisted square steel.

[0003] The utility model patent with publication number CN220129318U in the prior art proposes a grating plate fixing device, which mainly consists of a grating clamp and a fixing part. It has a simple structure, is small and lightweight, and is easy and quick to install. Through reasonable design, it reduces the amount of raw materials used, lowers production costs, and can achieve vertical fixing of the grating plate.

[0004] However, during use, it is inconvenient to pre-tighten the device according to the thickness of the edging plate of the steel grating. Its size is fixed, which reduces the applicability of the device and makes it difficult for users to splice and fix the steel grating later, which brings many inconveniences to the user's work. Therefore, we need to upgrade and modify it based on the existing technology. Utility Model Content

[0027] like Figure 1As shown in Figure 5, this embodiment provides a quick-fixing device for steel grating, including a device body 1. The device body 1 contains a steel grating body 1 2 and a steel grating body 2 3. A edging plate 1 21 is installed inside the steel grating body 1 21. A load-bearing flat steel 22 is installed on the inner wall of the edging plate 1 21. A torsion bar 24 is installed inside the load-bearing flat steel 22.

A torsion bar 2 34 is provided inside the load-bearing flat steel 2 32. A fixing mechanism 4 is installed on the edging plate 1 21 and the edging plate 2 31. A U-shaped clip 41 is installed in the fixing mechanism 4. The U-shaped clip 41 is inserted into the edging plate 1 21 and the edging plate 2 31. Extension buckles 42 are connected to the left and right sides of the U-shaped clip 41. The extension buckles 42 have mounting holes 43.

[0028] Preferably, an adjustment mechanism 5 is provided inside the U-shaped clamp 41. The adjustment mechanism 5 is equipped with a screw hole 51 and a screw hole 52. The screw hole 51 and the screw hole 52 are located inside the U-shaped clamp 41. A threaded rod 53 is screwed into the screw hole 51, and a threaded rod 54 is screwed into the screw hole 52. The rear end of the threaded rod 53 is connected to a knob 55, and the front end of the threaded rod 53 is connected to a clamping plate 58. The rear end of the threaded rod 54 is connected to a knob 56, and the front end of the threaded rod 54 is connected to a clamping plate 59.

[0029] By setting knob 55 and knob 56, threaded rod 53 and threaded rod 54 can be adjusted, thereby driving clamping plate 58 and clamping plate 59 to pre-tighten the device, ensuring the safety and stability of the device during use and improving the applicability of the device.

[0030] Preferably, the load-bearing flat steel 1 22 is provided with a slot 1 23, and the load-bearing flat steel 2 32 is provided with a slot 2 33. Multiple sets of slots 1 23 and slot 2 33 are provided, and torsion bar 1 24 and torsion bar 2 34 are respectively installed in slots 1 23 and slot 2 33.

[0031] By setting slot 1 23 and slot 2 33, users can easily install and fix torsion bar 1 24 and torsion bar 2 34, increasing the practicality and convenience of the device.

[0032] Preferably, multiple sets of mounting holes 43 are provided, and hexagonal bolts 44 are installed in the mounting holes 43. Washers 45 are movably fitted on the hexagonal bolts 44.

[0033] By setting the washer 45, wear on the surface of the extension buckle 42 is prevented from occurring during the pre-tightening process of the hex bolt 44.

[0034] Preferably, anti-slip strips 57 are fixedly installed on the outer walls of knob 1 55 and knob 2 56, and multiple sets of anti-slip strips 57 are provided.

[0035] By setting anti-slip strips 57, the user's hands are prevented from slipping and making it difficult to turn the knobs 55 and 56, thus providing convenience for the user.

[0036] Preferably, guide blocks 592 are fixedly installed above both clamping plate 58 and clamping plate 59, and guide grooves 591 are opened in the U-shaped clamp 41, with guide blocks 592 slidably installed in the guide grooves 591.

[0037] By setting guide block 592 and guide groove 591, the direction of movement of clamping plate 1 58 and clamping plate 2 59 can be guided, so as to avoid the positional deviation of clamping plate 1 58 and clamping plate 2 59 during movement.

[0038] Preferably, anti-slip pads 593 are fixedly installed on the inner walls of both the first clamp 58 and the second clamp 59;

[0039] By setting anti-slip pads 593, the stability and anti-slip properties of clamps 58 and 59 can be increased, ensuring the safety of clamps 58 and 59 during use.

[0040] The working principle and process of this utility model are as follows: When the device needs to be spliced ​​and fixed during use, the user moves the steel grating body 1 (2) and steel grating body 2 (3) to the required installation position, aligns and tightly attaches the edge plates 1 (21) and 2 (31) of the steel grating body 1 (2) and steel grating body 2 (3), and then inserts the U-shaped clips 41 onto the edge plates 1 (21) and 2 (31) in sequence. Next, the user places the washers 45 onto the hexagonal bolts 44, and then inserts the hexagonal bolts 44 into the mounting holes 43 of the extension buckles 42 in sequence. After insertion, the hexagonal bolts 44 are pre-tightened. After pre-tightening, the steel grating body 1 (2) and steel grating body 2 (3) are fixed. This allows for quick installation and fixing of steel gratings that need to be spliced, ensuring the safety and stability of the steel gratings during use, providing convenience for the user, and facilitating later disassembly and replacement of the device, avoiding difficulties in maintenance. In situations where it is necessary to limit and fix steel gratings of different thicknesses, the user manually rotates knob 55 and knob 56. Knob 55 drives threaded rod 53 to rotate within screw hole 51. As threaded rod 53 rotates, it moves clamping plate 58 closer to edge plate 21 until the anti-slip pad 593 of clamping plate 58 is in close contact with edge plate 21. Simultaneously, when knob 56 rotates, it drives threaded rod 54 to rotate within screw hole 52. As threaded rod 54 rotates, it moves clamping plate 59 closer to edge plate 31 until the anti-slip pad 593 of clamping plate 59 is in close contact with edge plate 31. At this point, clamping plates 58 and 59 clamp edge plate 21 and edge plate 31, thus fixing the device. This allows for limiting and fixing the device according to its thickness, increasing its applicability, flexibility, and practicality, meeting various installation needs, and providing convenience for users.
