Description

Technical Field

[0001] This utility model relates to the field of steel grating, specifically a steel grating that is easy to assemble. Background Technology

[0002] Steel grating is an open metal component made of load-bearing flat steel bars and crossbars (twisted square steel, square steel, round steel, etc.) arranged at certain intervals and fixed by welding or press-locking processes. It is widely used in platforms, walkways, stair treads, drainage ditch covers, etc. in factories, mines, ports, and other places. However, existing steel gratings are not convenient for quick assembly and disassembly of the outer frame and the main body of the steel grating, thus affecting the efficiency of assembly and disassembly.

[0003] To address the aforementioned issues, a steel grating that is easy to assemble is proposed here. Utility Model Content

[0004] The purpose of this invention is to provide a steel grating that is easy to assemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel grating that is easy to assemble, comprising an outer frame and an annular movable base. The outer frame has four side openings for mounting slots, each of the four mounting slots has a mounting block engaged within it, and a steel grating body is fixedly mounted between the four mounting blocks. Each of the four mounting slots has an inner groove, and each of the four grooves has a hinged seat fixedly mounted at its top. Each hinged seat has a limiting member hinged to its bottom end. Each groove has several supporting springs fixedly connected to its bottom, one end of each supporting spring being fixedly connected to one of the four limiting members. Each limiting member has an auxiliary pull rope fixedly connected to its side closest to the supporting spring, and the end of each auxiliary pull rope away from the limiting member extends to the outside and is fixedly connected to the annular movable base. Each annular movable base has auxiliary handles fixedly connected to both sides.

[0006] The four mounting slots engage with the four mounting blocks, and the four connecting slots engage with the four connecting posts, facilitating initial positioning of the steel grating body. The four limiting members, supported by several springs, engage with the four limiting slots, further positioning the steel grating body and enabling rapid assembly of the steel grating body to the outer frame. By applying significant force to slide the two auxiliary handles downwards, the annular moving seat moves downwards, pulling the four auxiliary ropes. This allows the four limiting members to retract into the four mounting slots, and by pushing the steel grating body upwards, the four connecting slots separate from the four connecting posts, facilitating rapid separation of the steel grating body from the outer frame.

[0007] Preferably, an annular moving groove is provided in the middle of the outer frame surface, and the annular moving groove is slidably connected to the annular moving seat. The annular moving groove facilitates the stable movement of the annular moving seat.

[0008] Preferably, each of the four auxiliary pull ropes has a rope hole at the connection point between the outer frame and the four auxiliary pull ropes. The four rope holes are respectively connected to the four auxiliary pull ropes, and the rope holes facilitate the stable movement of the auxiliary pull ropes.

[0009] Preferably, each of the four mounting blocks has a limiting groove on the side away from the main body of the steel grating. The four limiting grooves are respectively set with four limiting members. The four limiting members are engaged with the four limiting grooves under the action of several supporting springs, thereby facilitating further limiting of the main body of the steel grating.

[0010] Preferably, each of the four placement slots is fixedly provided with a connecting post at the connection point between it and the four placement blocks, and each of the four placement blocks is provided with a connecting slot at the connection point between it and the four placement slots. Each of the four connecting slots is engaged with the four connecting posts. The engagement of the four connecting slots with the four connecting posts facilitates the initial positioning of the steel grating body.

[0011] Preferably, the steel grating body includes a plurality of horizontal steel bars, and a plurality of evenly distributed vertical steel bars are fixedly arranged between the plurality of horizontal steel bars.

[0012] Preferably, both the horizontal and vertical steel bars include a base layer, a reinforcing layer is fixedly connected to the surface of the base layer, and an anti-corrosion layer is fixedly connected to the surface of the reinforcing layer. The anti-corrosion layer can improve the corrosion resistance of the steel grating body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the four mounting slots engage with the four mounting blocks respectively, and the four connecting slots engage with the four connecting posts respectively, which facilitates the initial positioning of the steel grating body. The four limiting members engage with the four limiting slots under the action of several support springs, which further facilitates the positioning of the steel grating body, thereby facilitating the rapid assembly of the steel grating body with the outer frame. By using a large force to slide the two auxiliary handles downward, the annular moving seat moves downward, thereby pulling the four auxiliary ropes, which in turn facilitates the retraction of the four limiting members into the four mounting slots. Then, the steel grating body is pushed upward, causing the four connecting slots to separate from the four connecting posts, thus facilitating the rapid separation of the steel grating body from the outer frame.

[0022] Please see Figure 1-6This utility model provides a steel grating that is easy to assemble, including an outer frame 1 and an annular movable base 10. The four sides of the inner side of the outer frame 1 are provided with mounting slots 2, and mounting blocks 3 are engaged inside each of the four mounting slots 2. A steel grating body 4 is fixedly installed between the four mounting blocks 3. Mounting grooves 5 are provided inside each of the four mounting slots 2. Hinge seats 6 are fixedly installed at the top of each of the four mounting grooves 5. Limiting members 7 are hinged to the bottom of each of the four hinge seats 6. Several supporting springs 8 are fixedly connected to the bottom of each of the four mounting grooves 5. One end of each supporting spring 8 is fixedly connected to one of the four limiting members 7. Auxiliary pull ropes 9 are fixedly connected to the side of each of the four limiting members 7 closest to the supporting springs 8. The ends of the four auxiliary pull ropes 9 away from the limiting members 7 extend to the outside and are fixedly connected to the annular movable base 10. Both sides of the annular movable base 10 are fixedly... The auxiliary handle 11 is connected to the steel grating body 4. The four mounting slots 2 are respectively engaged with the four mounting blocks 3 and the four connecting slots 14 are respectively engaged with the four connecting posts 15 to facilitate the initial positioning of the steel grating body 4. The four limiting members 7 are engaged with the four limiting grooves 16 under the action of several supporting springs 8, which further facilitates the positioning of the steel grating body 4. This makes it easy to quickly assemble the steel grating body 4 with the outer frame 1. By using a large force to slide the two auxiliary handles 11 downward, the annular moving seat 10 is moved downward, which pulls the four auxiliary pull ropes 9. This makes it easy to retract the four limiting members 7 into the four mounting slots 5. Then, the steel grating body 4 is pushed upward, which makes the four connecting slots 14 separate from the four connecting posts 15, thus facilitating the quick separation of the steel grating body 4 from the outer frame 1.

[0023] An annular moving groove 12 is provided in the middle of the surface of the outer frame 1. The annular moving groove 12 is slidably connected to the annular moving seat 10. A rope hole 13 is provided at the connection between the outer frame 1 and the four auxiliary pull ropes 9. The four rope holes 13 are respectively connected to the four auxiliary pull ropes 9. A limit groove 16 is provided on the side of the four mounting blocks 3 away from the steel grating body 4. The four limit grooves 16 are respectively set to correspond to the four limit pieces 7.

[0024] In use, the annular moving groove 12 facilitates the stable movement of the annular moving seat 10, the rope hole 13 facilitates the stable movement of the auxiliary pull rope 9, and the four limiting pieces 7 are engaged with the four limiting grooves 16 under the action of several supporting springs 8, thereby facilitating further limiting of the steel grating body 4.

[0025] Connecting posts 15 are fixedly installed at the connection points of the four mounting slots 2 and the four mounting blocks 3 respectively. Connecting slots 14 are opened at the connection points of the four mounting blocks 3 and the four mounting slots 2 respectively. The four connecting slots 14 are respectively engaged with the four connecting posts 15. The steel grating body 4 includes a number of horizontal steel bars 41. A number of evenly distributed vertical steel bars 42 are fixedly installed between the number of horizontal steel bars 41. Both the horizontal steel bars 41 and the vertical steel bars 42 include a base layer 411. A reinforcing layer 412 is fixedly connected to the surface of the base layer 411. An anti-corrosion layer 413 is fixedly connected to the surface of the reinforcing layer 412.

[0026] In use, the four connecting slots 14 are engaged with the four connecting posts 15 to facilitate the initial positioning of the steel grating body 4. The anti-corrosion layer 413 can improve the anti-corrosion performance of the steel grating body 4.

[0027] In this embodiment, the steel grating body 4 is initially positioned by engaging with the four mounting slots 2 and the four mounting blocks 3, and by engaging with the four connecting slots 14 and the four connecting posts 15. The four limiting members 7 engage with the four limiting grooves 16 under the action of several supporting springs 8, further positioning the steel grating body 4. This facilitates the rapid assembly of the steel grating body 4 with the outer frame 1. By applying greater force to slide the two auxiliary handles 11 downwards, the annular moving seat 10 moves downwards, pulling the four auxiliary ropes 9. This allows the four limiting members 7 to retract into the four mounting slots 5, and then the steel grating body 4 is pushed upwards, causing the four connecting slots 14 and the four connecting posts 15 to separate, thus facilitating the rapid separation of the steel grating body 4 from the outer frame 1.
