[0040] The drain ditch cover plate is usually located in urban roads, residential areas, garage entrances and other places, and is used for the drain ditch of the vehicle passing road. In the actual use process of the traditional drain ditch cover plate, due to the frequent passing of vehicles, especially heavy vehicles, it is easy to produce larger vibration and noise, which affects the life quality of surrounding residents and the comfort of pedestrians.

[0041] In the related art, although a buffer pad is arranged between the drain ditch cover plate and the opening of the drain ditch to perform buffering and noise reduction, due to the softness of the buffer pad, when the vehicle passes the cover plate, the end of the cover plate may be lifted, and after the vehicle leaves, the cover plate falls down and collides to produce noise.

[0042] The utility model discloses a main purpose is to propose a cover plate subassembly and drainage ditch structure, aims at at least solving relevant technique, although there is the setting of buffer pad between the opening of drainage ditch cover plate and drainage ditch to carry out the buffering and the noise reduction, but because the softness of buffer pad, when the vehicle passes the cover plate, can cause the end of cover plate to be raised, after the vehicle leaves, the noise that the cover plate falls down and hits, technical problem.

[0043] Please refer to Figures 1 to 4 In the utility model an embodiment, the cover plate subassembly 100, to cover the opening 201 of drainage ditch main part 200, the cover plate subassembly 100 includes cover plate main body 1, first buffer pad 2 and limit structure 3, the cover plate main body 1 is set with via 101 on it, has with the side edge portion 102 for supporting at the circumference of opening 201, first buffer pad 2 includes support portion 21, support portion 21 is arranged at the downside of side edge portion 102, limit structure 3 includes the convex part 31 and recess 32 separately arranged on side edge portion 102 and first buffer pad 2, the convex part 31 and recess 32 are clamped together.

[0044] In the technical scheme of the embodiment, the cover plate main body 1 is provided with a via 101, and further has a side edge portion 102 for supporting at the circumference of the opening 201, the first buffer pad 2 includes a support portion 21 arranged at the downside of the side edge portion 102, and the limit structure 3 includes a convex portion 31 and a recess 32 separately arranged on the side edge portion 102 and the first buffer pad 2, which are clamped together. In this way, when a vehicle or a pedestrian walks on the cover plate main body 1, the support portion 21 can dampen the side edge portion 102, thereby reducing noise. At the same time, the limit structure 3 fixes the first buffer pad 2 and the side edge portion 102 through the cooperation of the convex portion 31 and the recess 32, so as to reduce the possibility of the deformation of the support portion 21 causing the end of the cover plate main body 1 to be raised, and further reduce the generation of noise.

[0045] The first buffer pad 2 is made of an elastic material, and the application does not limit the specific elastic material. The elastic material can be rubber or silicone.

[0046] It should be noted that the convex portion 31 can be arranged on the first buffer pad 2, and the recess 32 can be arranged on the side edge portion 102. Alternatively, the convex portion 31 can be arranged on the side edge portion 102, and the recess 32 can be arranged on the first buffer pad 2.

[0047] The matching orientation of the convex part 31 and the concave part 32 is various, for example, the convex part 31 and the concave part 32 can be matched in the horizontal direction, or matched in the up-down direction, when the convex part 31 and the concave part 32 are matched in the horizontal direction, although the fixing effect of the first buffer pad 2 and the cover plate body 1 is better, when the cover plate body 1 needs to be replaced due to damage, disassembly is more troublesome. Figure 3 and Figure 4 The convex part 31 is protrusively arranged on the upper side of the supporting part 21, and the concave part 32 is arranged on the lower side of the side part 102; in this way, the convex part 31 and the concave part 32 are matched in the up-down direction, when the cover plate body 1 is damaged, the cover plate body 1 can be removed upward, and the disassembly is convenient, when installing, through the positioning of the convex part 31 and the concave part 32, the cover plate body 1 can be installed with the first buffer pad 2 by pressing downward.

[0048] The convex part 31 can be separately formed and then fixed and installed on the supporting part 21, or can be integrally formed with the supporting part 21, in the embodiment of the utility model, the convex part 31 is integrally arranged with the supporting part 21; in this way, the forming of the overall structure is simpler, and the convex part 31 also adopts the same elastic material as the first buffer pad 2, it can be understood that the cover plate body 1 is usually made of hard material, when the vehicle passes through the cover plate body 1, the elasticity of the convex part 31 can also play a buffering role, and the generation of noise is reduced.

[0049] Specifically, in the embodiment of the utility model, please refer to Figure 2 and Figure 4The side portion 102 is a side portion of the cover plate body 1 in a first horizontal direction. The cover plate body 1 comprises a frame 11 and connecting ribs 12, the connecting ribs 12 are provided in plurality and extend in the first horizontal direction, and the plurality of connecting ribs 12 are arranged in the frame 11 in a second horizontal direction to form the through holes 101. The frame 11 and part of the plurality of connecting ribs 12 constitute the side portion 102. The lower side of each of the plurality of connecting ribs 12 is provided with a groove, and the plurality of grooves constitute the recess 32. In this way, the recess 32 and the convex portion 31 are formed by opening the groove at the lower end of each connecting rib 12, thereby fixing the cover plate body 1 and the first buffer pad 2. In another embodiment, the groove can be opened at the lower side of the frame 11 to form the convex portion 31. However, compared with the groove provided at the lower side of the connecting rib 12, it is obviously easier to open a small gap at the lower side of each connecting rib 12, and the processing is more convenient. If the groove is opened at the lower side of the frame 11, a long gap needs to be opened, which is more troublesome.

[0050] For one cover plate body 1, the side portion 102 has two, and the first buffer pad 2 needs to support two side portions 102. However, two first buffer pads 2 can support two side portions 102 respectively, or one first buffer pad 2 can support two side portions 102. When one first buffer pad 2 is used to support two side portions 102, if the span of the two side portions is large, the span of the first buffer pad 2 as a whole will also be large. Therefore, there will be a part in the middle of the first buffer pad 2 in a suspended state without supporting the cover plate body 1, which is a waste. In the embodiments of the present application, please refer to Figure 1 and Figure 2 The side portion 102 is a side portion of the cover plate body 1 in a first horizontal direction. Corresponding to one cover plate body 1, the first buffer pad 2 is provided in two, and the two first buffer pads 2 are arranged in a spaced manner in the first horizontal direction. The support portions 21 of the two first buffer pads 2 are arranged at the lower sides of the two side portions 102 respectively. In this way, the first buffer pad 2 is provided in two, and the support portions 21 of the two first buffer pads 2 support the two side portions 102 respectively. Compared with the first buffer pad 2 provided with only one, the first buffer pad 2 does not need an additional connecting portion to connect the two support portions 21. The utilization rate of the first buffer pad 2 is higher, the material is saved, and when the drainage ditch body 200 is curved, the installation and production are easier when two first buffer pads 2 are used.

[0051] The cover plate body 1 may not only move in the up-down direction when actually subjected to external force of vehicles and pedestrians, but also may be subjected to horizontal force. If the first buffer pad 2 only needs to buffer the lower side of the cover plate body 1, the side edge part 102 of the cover plate body 1 may still rigidly collide with the opening 201 of the drain ditch body 200 in the horizontal direction, thereby generating noise. Therefore, in the embodiment of the utility model, the first buffer pad 2 further comprises a side extension part 22, one end of the side extension part 22 is connected with the supporting part 21, and the other end extends upward; the side extension parts 22 of the two first buffer pads 2 respectively abut against the outward side of the two side edge parts 102; in this way, the side extension part 22 and the supporting part 21 integrally present an L shape, and in addition to protecting the lower side of the side edge part 102, the outward side of the side edge part 102 is also protected, thereby being able to play a buffering role between the opening 201 and the side edge part 102 when the cover plate body 1 moves in the horizontal direction, thereby reducing noise.

[0052] For a longer drain ditch body 200, the cover plate body 1 is usually arranged in a split body, that is, the cover plate body 1 comprises a plurality of cover plate split bodies arranged independently in a second horizontal direction. In some embodiments, the supporting part 21 of one first buffer pad 2 can correspond to one cover plate split body, and in some embodiments, the supporting part 21 can be arranged at the lower side of the side edge part 102 of the plurality of cover plate split bodies, that is, one first buffer pad 2 can correspond to a plurality of cover plate split bodies.

[0053] When the cover plate split body is subjected to external force, it may also move in the second horizontal direction, thereby possibly causing collision between two cover plate split bodies and generating noise. In order to reduce the possibility of noise generated by collision between two cover plate split bodies, please refer to Figure 1 and Figure 2 In the embodiment of the utility model, the cover plate assembly 100 further comprises at least one second buffer pad 4 arranged between adjacent two cover plate split bodies. In this way, adjacent two cover plate split bodies are damped and buffered by the second buffer pad 4, thereby reducing the possibility of

[0054] The second buffer pad 4 can be separately placed between two cover plate split bodies, or can be integrally formed with the first buffer pad 2. When the first buffer pad 2 and the second buffer pad 4 are arranged in a split body, it is more convenient to replace if damaged. When the first buffer pad 2 and the second buffer pad 4 are integrally formed, installation and production will be easier. Therefore, both ways have their own advantages, and specific factors such as the length and width of the drain ditch body 200 are considered when actually selecting.

[0055] The utility model discloses still a kind of drainage ditch structure 1000, the drainage ditch structure 1000 including drainage ditch main body 200 and cover plate subassembly 100, the specific structure of this cover plate subassembly 100 refers to above-mentioned embodiment, since the drainage ditch structure 1000 of the utility model adopts all technical solutions of above-mentioned all embodiments, at least have all beneficial effects brought by the technical scheme of above-mentioned embodiment, here no longer repeat.

[0056] The above-mentioned is only the exemplary embodiment of the utility model, and not therefore limit the patent range of the utility model, any equivalent structure transformation made in the technical concept of the utility model using the utility model specification and drawing contents, or direct / indirectly applied in other related technical fields are included in the patent protection range of the utility model.
