[0001] This utility model relates to the field of rain grate, and in particular to a fracture-resistant reinforced rain grate with an elastic buffer structure. Background Technology

[0002] Storm drain grates are typically installed on roads with pedestrian and vehicle traffic. Traditional storm drain grates are mostly made of cast iron or steel grating directly fixed to the drain outlet. After being subjected to the instantaneous impact load of vehicles, the fatigue load of long-term rolling, and the trampling of pedestrians, storm drain grates are prone to breakage. This not only affects the aesthetics and cleanliness of the road surface, but also may cause pedestrians to trip, bicycle wheels to get stuck, and wheelchairs to get stuck, greatly increasing safety hazards. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fracture-resistant reinforced rain grate with an elastic buffer structure, which can solve the problem that traditional rain grate is prone to breakage and thus poses a safety hazard.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A fracture-resistant reinforced rain grate with an elastic buffer structure includes a frame, which is embedded in the ground and its top surface is flush with the road surface. A support frame is slidably connected inside the frame, and a grate frame is detachably connected to the support frame. The outer side of the grate frame fits against the inner side of the frame. Several crossbeams are provided inside the grate frame, and a buffer structure is provided below the grate frame.

[0006] Based on the above technical solutions, the present invention may also adopt the following further technical solutions, or combine these further technical solutions:

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote elements with the same or similar functions throughout. However, it should be understood that the drawings are for illustrative purposes only and should not be construed as limiting this utility model. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product size. It is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this utility model.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0023] This utility model provides a fracture-resistant reinforced rain grate with an elastic buffer structure, including a frame 1, which is embedded in the ground and its top surface is flush with the road surface. A support frame 11 is slidably connected inside the frame 1, and a grate frame 17 is detachably connected to the support frame 11. The outer side of the grate frame 17 is fitted with the inner side of the frame 1. Several crossbeams 19 are provided inside the grate frame 17, and a buffer structure is provided below the grate frame 17.

[0024] Anti-slip pads 21 are fixed to the top of the crossbeam 19, such as... Figure 4 As shown, the surface of the anti-slip sheet 21 has multiple protrusions to increase friction and reduce the risk of pedestrians slipping.

[0025] A reinforcing rib 20 is fixed to the bottom of the crossbeam 19 to improve the structural strength of the rain grate and further prevent the rain grate from breaking.

[0026] The buffer structure includes a base frame 2, which is fixed to the bottom of the inner wall of the frame 1. Several spring cylinders 3 are fixed circumferentially inside the base frame 2. A sliding plate 4 is slidably connected inside the spring cylinders 3. A second sliding rod 7 is fixed on the top of the sliding plate 4, and a first sliding rod 5 is fixed on the bottom of the sliding plate 4. The upper end of the second sliding rod 7 and the lower end of the first sliding rod 5 extend out of the spring cylinders 3 respectively. The upper end of the second sliding rod 7 is fixedly connected to the bottom of the support frame 11. A first buffer spring 6 and a second buffer spring 8 are provided inside the spring cylinders 3. The first buffer spring 6 is sleeved on the first sliding rod 5, and the second buffer spring 8 is sleeved on the second sliding rod 7.

[0027] Several pads 9 are fixed below the support frame 11. The position and number of the pads 9 correspond one-to-one with the second slide rod 7. The pads 9 are used to connect the second slide rod 7. Rubber ring pads 10 are fixed below the pads 9 and above the spring cylinder 3 respectively. When the pads 9 slide downwards, the two sets of rubber rings 10 may collide together. At this time, the damage caused by the pads 9 directly colliding with the top surface of the spring cylinder 3 can be reduced.

[0028] The inner wall of the frame 1 is provided with a groove 15, and a roller 13 is rotatably connected inside the support frame 11. One side of the roller 13 protrudes from the outer wall of the support frame 11 and is installed in the groove 15.

[0029] Several insert rods 16 are fixed on the top of the support frame 11, and slots corresponding to the insert rods 16 are provided on the bottom of the grate frame 17. The grate frame 17 is positioned by the insert rods 16 and the slots and is limited and connected to the support frame 11.

[0030] The top of the comb frame 17 is lower than the top of the border 1.

[0031] A baffle 22 is fixed to the bottom of the grate frame 17. The baffle 22 and the frame 1 enclose the bottom frame 2 and the spring cylinder 3 therein.

[0032] The grate frame 17 has a pry hole 18 on top. Workers can insert a pry bar into it to lift the entire rain grate directly.

[0033] The application of this utility model's fracture-resistant reinforced rain grate with an elastic buffer structure is as follows:

[0034] When a vehicle / pedestrian passes by, the grate frame 17 is compressed and sinks slightly downward, thereby causing the support frame 11 to move downward. The second sliding rod 7 pushes the sliding plate 4 downward, and the sliding plate 4 pushes the first sliding rod 5 downward. At this time, the first buffer spring 6 is compressed, absorbing the downward impact force. When the vehicle / pedestrian leaves, the load overflows, and the first buffer spring 6 rebounds upward, pushing the sliding plate 4 upward. The sliding plate 4 pushes the second sliding rod 7 upward, thereby causing the support frame 11 and the grate frame 17 to move upward and reset. During this process, due to the second buffer spring 8, the impact force when the first buffer spring 6 rebounds can be absorbed, and the upward rebound inertia can be suppressed. By setting the first buffer spring 6 and the second buffer spring 8 to have opposite buffering forces, the vertical buffering and shock absorption effect of the rain grate can be improved.

[0035] Based on the description and drawings of this utility model, those skilled in the art can easily manufacture or use the fracture-resistant reinforced rain grate with an elastic buffer structure of this utility model, and can produce the positive effects described in this utility model.
