Specific implementation

[0021] The utility model is further explained in connection with the drawings and examples:

[0022] Example 1: a kind of environmental protection durable EVA waterproof board with clamping locking structure, refer to Figures 1 to 4The system includes a base plate 1, with columns 11 mounted on both sides of the top of the base plate 1. A connecting shaft 21 is rotatably connected between the two columns 11. A waterproof membrane roll 2 is mounted on the outside of the connecting shaft 21, and an EVA waterproof membrane body 3 is wound around the outside of the waterproof membrane roll 2. A support rod 4 is provided at one end of the outside of each of the two columns 11. A horizontal plate 41 is installed between the two support rods 4. Top rods 42 are movably inserted through both sides of the horizontal plate 41. A limit plate 45 is fixedly connected between the tops of the two top rods 42. A first spring 43 is sleeved on the outside of each of the two top rods 42 above the horizontal plate 41. The two ends of the two first springs 43 are respectively connected to the horizontal plate 41 and the limit plate 45. An arc-shaped locking plate 44 is fixedly connected to the bottom of the two top rods 42. During operation, when the waterproof membrane roll is pulled... When the EVA waterproof sheet body 3 is unwound from the roller 2, the connecting shaft 21 allows the waterproof sheet roller 2 to rotate independently to unwind the EVA waterproof sheet body 3, thus facilitating the unwinding of the EVA waterproof sheet body 3. At the same time, the elastic force of the first spring 43 pushes the arc-shaped locking plate 44 to always press and wrap around the EVA waterproof sheet body 3 on the outside of the waterproof sheet roller 2, thereby preventing the EVA waterproof sheet body 3 from becoming loose during unwinding without affecting the unwinding of the EVA waterproof sheet body 3. Furthermore, the elastic force of the first spring 43 pushes the arc-shaped locking plate 44 to always adhere to the EVA waterproof sheet body 3, thus eliminating the need for manual adjustment of the EVA waterproof sheet body 3 according to the thickness of the EVA waterproof sheet body 3 wrapped on the waterproof sheet roller 2, which is more convenient.

[0023] For details, see Figure 3 Each of the two columns 11 is provided with a fixing block 12 at its top.

The semi-circular groove 14 facilitates the limiting rotation of the connecting shaft 21, thereby improving the stability of the waterproof membrane roll 2 when unwinding. Furthermore, by turning the fixing bolt 13, the fixing block 12 can be removed from the column 11, which facilitates the disassembly and replacement of the unwound waterproof membrane roll 2.

[0024] Further, see Figure 1 The support rod 4 is rotatably connected to the outside of the column 11 via a rotating shaft. A set screw 46 is provided at one end of the outside of the support rod 4. By turning the set screw 46, the support rod 4 can be limited and rotated, thus facilitating the horizontal rotation of the support rod 4 and preventing the horizontal plate 41 from affecting the disassembly and assembly of the waterproof board roller 2.

[0025] It is worth noting that, see Figure 3The opposite end of the two stand columns 11 is provided with a sliding groove 5, the sliding groove 5 is slidably connected with a sliding block 51, the inner cavity bottom of the two sliding grooves 5 is provided with a second spring 52, the other end of the two second springs 52 is connected with the two sliding blocks 51, the opposite end of the two sliding blocks 51 is provided with an arc-shaped friction plate 53, the concave side of the arc-shaped friction plate 53 is provided with an arc-shaped non-slip pad 54, the concave end of the arc-shaped non-slip pad 54 is matched with the outer side of the connecting shaft 21, the arc-shaped friction plate 53 is pushed by the elastic force of the second spring 52 to make the arc-shaped non-slip pad 54 contact with the outer side of the connecting shaft 21, so that the inertia of the waterproof board roll 2 during unwinding can reduce the rotation of the waterproof board roll 2 to cause the loosening of part of the wound EVA waterproof board body 3.

[0026] It is worth noting that, referring to Figure 4 The EVA waterproof board body 3 comprises a first EVA waterproof layer 31, a reinforcing net 32, a second EVA waterproof layer 33 and a geotextile layer 34, the first EVA waterproof layer 31, the reinforcing net 32, the second EVA waterproof layer 33 and the geotextile layer 34 are sequentially connected from top to bottom, the strength of the EVA waterproof board body 3 is increased through the reinforcing net 32, and the durability of the EVA waterproof board body 3 is improved.

[0027] In addition, the components of the utility model are all general standard components or components known by the person skilled in the art, the structure and principle of which can be known by the person skilled in the art through a technical manual or through a conventional experimental method, and the person skilled in the art can realize it completely, and it is needless to say, and the content protected by the utility model does not involve the improvement of the internal structure and method.
