Description

Technical Field

[0001] This utility model relates to the field of steel grating technology, and more particularly to a steel grating that is easy to open and close. Background Technology

[0002] Steel grating can be used as work platforms, stair treads, drainage ditch covers, etc. Among them, drainage ditch covers are used as covers for sidewalks, driveways, courtyards or building floors as water ditches, pipeline trenches, underground passages, ventilation shafts, light wells, inspection wells, etc., and are made of steel grating by pressure welding.

[0003] Currently, the steel grating used for drainage ditches requires staff to regularly clean foreign objects from the drainage ditches during long-term use. However, most steel gratings are fixed at the four corners of the frame with multiple fastening bolts. When it is necessary to open the steel grating, staff need to remove the multiple bolts at the four corners one by one. However, removing the bolts is time-consuming and laborious, making it very inconvenient to open and close each time, which inconveniences maintenance and cleaning. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a steel grating that is easy to open and close. The specific technical solution is as follows:

[0005] The steel grating is easy to open and close, including a frame. The frame has two sets of horizontal stops symmetrically arranged in a first direction. Each set of horizontal stops includes a second horizontal grating and a plurality of first horizontal gratings arranged in the first direction. The plurality of first horizontal gratings are connected to each other by a plurality of first ropes. One end of the first rope is connected to the frame and the other end of the first rope is connected to the second horizontal grating. Two second horizontal gratings are located at the opposite ends of the two sets of horizontal stops and can be fixedly connected together by a first fixing component.

[0006] As an improvement to the above technical solution: the frame is symmetrically provided with two sets of vertical blocks in two directions. Each set of vertical blocks includes a second vertical grid plate and a plurality of first vertical grid plates arranged in the second direction. The plurality of first vertical grid plates are connected to each other by a second rope. One end of the second rope is connected to the frame and the other end of the second rope is connected to the second vertical grid plate. Two second vertical grid plates are located at the opposite ends of the two sets of vertical blocks. The two second vertical grid plates can be fixedly connected together by a second fixing component.

[0007] As an improvement to the above technical solution: the inner wall of the frame is provided with a first sliding groove in the second direction, and the ends of the second vertical grid plate and the ends of the plurality of first vertical grid plates are slidably connected in the first sliding groove; the inner wall of the frame is provided with a second sliding groove in the first direction, and the ends of the second horizontal grid plate and the ends of the plurality of first horizontal grid plates are slidably connected in the second sliding groove.

[0008] As an improvement to the above technical solution: when two second horizontal grid plates are pulled close to each other, multiple first ropes are in a taut state; when two second vertical grid plates are pulled close to each other, multiple second ropes are in a taut state.

[0009] As an improvement to the above technical solution: the first fixing component includes a first fixing bolt, which is threaded between two second horizontal grid plates; the second fixing component includes a second fixing bolt, which is threaded between two second vertical grid plates.

[0010] The beneficial effects of this utility model are:

[0011] When closing the opening of the frame of this application, the two second horizontal grid plates are moved in opposite directions. The first rope synchronously drives multiple first horizontal grid plates into an unfolded state until the two second horizontal grid plates come into contact. The two second horizontal grid plates are then fixed by the first fixing bolt. The taut first rope fixes the position of the second horizontal grid plates and multiple first horizontal grid plates, thus closing the opening of the frame with the first and second horizontal grid plates. When opening the frame, only one first fixing bolt needs to be removed, and the two second horizontal grid plates are moved away from each other, causing multiple first horizontal grid plates to move towards the inside of the frame, thus opening the frame. This allows for convenient and quick opening or closing of the frame, facilitating the maintenance of the frame's drainage system.

[0012] Furthermore, in this application, when opening or closing the opening of the frame, only the horizontal space of the frame needs to be occupied, and the vertical space of the frame does not need to be occupied. In this way, even if there are foreign objects blocking the top of the frame, it will not affect the opening or closing of the frame. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Example

[0018] Please refer to Figures 1-2 The steel grating, designed for easy opening and closing, includes a frame 1. The frame 1 has two sets of horizontal supports symmetrically arranged in a first direction. Each set of horizontal supports includes a second horizontal grating 5 and multiple first horizontal gratings 4 arranged in the first direction. The multiple first horizontal gratings 4 are connected by multiple first ropes 41. One end of each first rope 41 is connected to the frame 1, and the other end is connected to the second horizontal grating 5. Two second horizontal gratings 5 ​​are located at opposite ends of the two sets of horizontal supports. The two second horizontal gratings 5 ​​can be fixedly connected together by a first fixing component. Specifically, the first direction corresponds to... Figure 1 The X direction in the diagram can be the length direction of frame 1, and the second direction corresponds to... Figure 1 The Y direction can be the width direction of frame 1.

[0019] In an optional embodiment: the frame 1 is symmetrically provided with two sets of vertical supports in two directions. Each set of vertical supports includes a second vertical grid plate 3 and multiple first vertical grid plates 2 arranged in the second direction. The multiple first vertical grid plates 2 are connected to each other by a second rope 21. One end of the second rope 21 is connected to the frame 1, and the other end of the second rope 21 is connected to the second vertical grid plate 3. Two second vertical grid plates 3 are located at the opposite ends of the two sets of vertical supports. The two second vertical grid plates 3 can be fixedly connected together by a second fixing component. Through the cross arrangement of the vertical supports and horizontal supports on the frame 1, a more complete grid-like steel grating can be formed. Specifically, the frame 1 is arranged in a U-shape to facilitate the connection of the horizontal supports and vertical supports to the frame 1.

[0020] In an optional embodiment: the inner wall of the frame 1 is provided with a first sliding groove 101 in the second direction, the end of the second vertical grid plate 3 and the ends of the plurality of first vertical grid plates 2 are slidably connected in the first sliding groove 101, the inner wall of the frame 1 is provided with a second sliding groove 102 in the first direction, the end of the second horizontal grid plate 5 and the ends of the plurality of first horizontal grid plates 4 are slidably connected in the second sliding groove 102, thereby allowing the horizontal and vertical blocks to move stably on the frame 1 and be limited on the frame 1.

[0021] In an optional embodiment: when two second horizontal grid plates 5 are pulled close to each other, multiple first ropes 41 are in a taut state; when two second vertical grid plates 3 are pulled close to each other, multiple second ropes 21 are in a taut state. Thus, multiple first vertical grid plates 2 can be locked in an immovable position by the second ropes 21, and multiple first horizontal grid plates 4 can be locked in an immovable position by the first ropes 41.

[0022] In an optional embodiment: the first fixing component includes a first fixing bolt 51, which is threaded between two second horizontal grid plates 5; the second fixing component includes a second fixing bolt 31, which is threaded between two second vertical grid plates 3, thereby facilitating the assembly and disassembly of the first vertical grid plates 2 and the second vertical grid plates 3.

[0023] Specifically, when closing the opening of the frame 1 of this application, the two second horizontal grid plates 5 are moved in opposite directions, and the first rope 41 simultaneously drives multiple first horizontal grid plates 4 to be in an unfolded state until the two second horizontal grid plates 5 come into contact. The two second horizontal grid plates 5 are then fixed by the first fixing bolt 51. The position of the second horizontal grid plates 5 and multiple first horizontal grid plates 4 is fixed by the taut first rope 41, so that the first horizontal grid plates 4 and the second horizontal grid plates 5 close the opening of the frame 1. When opening the frame 1, only one first fixing bolt 51 needs to be removed, and the two second horizontal grid plates 5 are moved away from each other, so that multiple first horizontal grid plates 4 move towards the inside of the frame 1, so that the opening of the frame 1 is opened. This allows the frame 1 to be opened or closed conveniently and quickly, facilitating the maintenance of the sewer of the frame 1.

[0024] Furthermore, in this application, when opening or closing the opening of the frame 1, only the horizontal space of the frame 1 needs to be occupied, and the vertical space of the frame 1 does not need to be occupied. In this way, even if there are foreign objects blocking the top of the frame 1, it will not affect the opening or closing of the frame 1.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
