Description

Technical Field

[0001] The utility model relates to the technical field of drainage boards, in particular to a drainage board. Background Art

[0002] The drainage board is made of a plastic base plate made of polystyrene or polyethylene, which is stamped into conical protrusions or convex points with stiffening ribs or hollow cylindrical porous shapes. The concave and convex hollow rib structure of the drainage board can quickly and effectively drain rainwater, greatly reducing or even eliminating the static water pressure of the waterproof layer. Through this active water diversion principle, the active waterproofing effect can be achieved.

[0003] In construction, drainage boards are often needed, and drainage boards are generally installed in blocks. Multiple drainage boards are installed and connected by screws. However, the connection and fixation by screws makes the installation of drainage boards not only troublesome, but also time-consuming and labor-intensive, thereby reducing the installation efficiency of the workers. At the same time, since the drainage boards are installed on the ground, when the drainage boards are spliced ​​together, the rearmost drainage board exceeds the installation position and needs to be cut. When cutting, the workers need to use external tools to cut it. In the cutting process, it is easy to cause the cutting position to shift, thereby affecting the flatness during subsequent cutting. Utility Model Content

[0004] The purpose of the present invention is to provide a drainage board to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a drainage board, comprising a drainage board body, and further comprising:

[0006] The lower and upper clamping plates are respectively fixed on the left and right sides of the drainage board body. The top of the lower clamping plate is fixedly connected with a plurality of plug-ins. Both sides of the plug-ins are provided with a limiting structure. The top of the upper clamping plate is provided with a plurality of slots for use with the plug-ins.

[0007] The movable grooves are provided on both sides of the upper clamping plate. The interior of the movable grooves is slidably connected with movable blocks. The top end of the movable block is hinged with a connecting plate. The other end of the connecting plate is fixedly connected with a cutting plate.

[0008] Preferably, the limiting structure includes movable grooves provided on both sides of the plug plate, a plurality of springs fixed inside the movable grooves, and a limiting plate fixed to the other end of the spring.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 As shown, a drainage board includes a drainage board body 1, and the left and right sides of the drainage board body 1 are respectively fixedly connected with a lower card plate 2 and an upper card plate 7 that cooperate with each other, the top of the lower card plate 2 is fixedly connected with a plurality of plug plates 3, and a limiting structure 4 is provided on both sides of the plug plates 3, and the top of the upper card plate 7 is provided with a plurality of slots 8 that cooperate with the plug plates 3, and both sides of the upper card plate 7 are provided with a movable groove 11, and the interior of the movable groove 11 is slidably connected with a movable block 12, and the top of the movable block 12 is hinged with a connecting plate 13, and the other end of the connecting plate 13 is fixedly connected with a cutting plate 14.

[0023] The limiting structure 4 includes a movable groove 41, a spring 42 and a limiting plate 43. The movable groove 41 is opened on both sides of the plug-in board 3. There are several springs 42, and they are all fixed inside the movable groove 41. The other end of the spring 42 is fixed to one side of the limiting plate 43. In this way, when the plug-in board 3 is inserted into the slot 8, the elastic force of the spring 42 itself can drive the limiting plate 43 to move outward, thereby limiting the plug-in board 3.

[0024] Several cutting grooves 9 are provided on the top of the drainage board body 1, and a placement groove 10 is provided at the rear of the top of the drainage board body 1. The two ends of the cutting grooves 9 and the placement grooves 10 are connected to the movable groove 11. Before cutting off the excess plates on the top of the drainage board body 1, the cutting plate 14 can be driven to move and be located at the position of the cutting groove 9 to facilitate subsequent cutting by tools. The size inside the placement groove 10 is larger than the size inside the cutting groove 9, and the size of the cutting plate 14 is adapted to the size inside the placement groove 10. In this way, when the cutting plate 14 is not in use, the cutting plate 14 can be clamped inside the placement groove 10 to facilitate subsequent use.

[0025] A plurality of limiting balls 15 are fixedly connected to the top of the lower card plate 2, and the surface of the limiting balls 15 cooperates with the bottom of the upper card plate 7, so that the fixing effect between the lower card plate 2 and the upper card plate 7 can be improved.

[0026] Slide grooves 5 are provided on both sides of the inner cavity of the movable groove 41, and sliders 6 are fixed on both sides of the limiting plate 43. The surface of the slider 6 is slidably connected to the inside of the slide groove 5, so that the limiting plate 43 can be auxiliary limited to prevent it from sliding out from the inside of the movable groove 41.

[0027] It is worth noting that: the technical features proposed in this technical solution should be regarded as prior art, and the specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional options in the field, and this technical solution will not further elaborate on them.

[0028] Working principle: When splicing two drain board bodies 1, the lower card plate 2 on the right side of the drain board body 1 can be aligned with the upper card plate 7 on the left side of the adjacent drain board body 1, so that the plug-in board 3 is inserted into the slot 8, and the limiting structure 4 is used to limit the inserted plug-in board 3 to prevent the adjacent drain board bodies 1 from loosening, so as to achieve the effect of facilitating splicing;

[0029] If it is necessary to cut the drain board body 1, the connecting plate 13 can be rotated to rotate the cutting plate 14 out from the inside of the placement groove 10, and then the moving block 12 is moved. During the movement, the connecting plate 13 drives the cutting plate 14 to deflect, so that the cutting plate 14 is located above the protrusion of the drain board body 1. In this way, when the moving block 12 moves, the cutting plate 14 will not touch the protrusion on the top of the drain board body 1, and move to the position where cutting is required. At this time, the cutting plate 14 can be located at the position of the cutting groove 9. Finally, the staff can use an external tool to cut the drain board body 1 along one side of the cutting plate 14, thereby improving the flatness during cutting.
