[0033] The present invention will now describe an anti-theft nut 1, a connecting clamp 2, and a pipeline conveying device.

[0034] Please see Figures 1 to 2 In a first aspect, this utility model provides an anti-theft nut 1. The anti-theft nut 1 includes a nut body 10 and a clamping part 12. The nut body 10 has a tubular structure, and a plurality of mounting grooves 11 are provided on the outer periphery of the nut body 10. The mounting grooves 11 are spaced apart around the outer periphery of the nut body 10. The clamping part 12 has an annular structure and is fixed to the outer periphery of the bottom of the nut body 10. The outer diameter of the clamping part 12 is larger than the outer diameter of the nut body 10.

[0035] Compared with the prior art, the anti-theft nut 1 provided in the first aspect embodiment of this application has the advantage of changing the general hexagonal prism structure of the nut body 10 to a cylindrical structure, and providing multiple mounting grooves 11 on the outer periphery of the cylindrical structure. This makes the anti-theft nut 1 in this solution compatible only with the special disassembly and installation tools of this factory, avoiding the need for general wrenches on the market to disassemble and install the anti-theft nut 1, greatly improving the security of the anti-theft nut 1, and solving the technical problem of easy disassembly and loss of nuts in the prior art.

[0036] Furthermore, the mounting groove 11 is vertically arranged on the outer periphery of the nut body 11.

[0037] In some embodiments, the mounting slot 11 may be as follows: Figure 1 , Figure 2 The structure shown is as follows. The mounting groove 11 includes a rectangular groove 111 and a semi-circular groove 112. One end of the rectangular groove 111 is connected to the upper plane of the nut body 10, and the other end of the rectangular groove 111 is connected to the semi-circular groove 112.

[0038] The rectangular groove 111 and the semi-circular groove 112 together form the mounting groove 11, and one end of the rectangular groove 111 is connected to the upper surface of the nut body 10. This not only makes it easier to use the special disassembly tool that is compatible with the anti-theft nut 1 during the disassembly and installation of the nut, but also makes it convenient to clean the silt or oil stains in the mounting groove 11 by setting the opening of the mounting groove 11.

[0039] Specifically, the height of the nut body 10 is 14mm-18mm. The outer diameter of the clamping part 12 is 30mm-34mm.

[0040] Please see Figure 3 Secondly, this utility model embodiment also provides a connecting clamp 2, which includes an anti-theft nut 1 mentioned in the first aspect.

[0041] Please see Figures 3 to 6 In conjunction with the second aspect, a connecting clamp 2 further includes a first clamp 21, a second clamp 22, and a bolt connection structure 23. The first clamp 21 has first connecting portions 211 at both ends, and the second clamp 22 has second connecting portions 221 at both ends. The first clamp 21 and the second clamp 22 are detachably connected via the bolt connection structure 23. The first clamp 21 and the second clamp 22 form a circular through hole, which is used to clamp the pipe to be connected.

[0042] The first clamp 21 and the second clamp 22 are detachably connected by a bolt connection structure 23, which facilitates the disassembly and installation of the first clamp 21 and the second clamp 22.

[0043] Please see Figure 7Based on the above embodiments, the connecting clamp 2 further includes a sealing gasket 25, which is embedded in the circular through hole, and the outer periphery of the sealing gasket 25 is in close contact with the inner side of the first clamp 21 and the second clamp 22. In actual use, the sealing gasket 25 is first placed on the pipe to be connected, then the first clamp 21 and the second clamp 22 are placed on both sides of the pipe to be connected, and finally the first clamp 21 and the second clamp 22 are connected into one unit by the bolt connection structure 23. At the same time, during the connection process of the first clamp 21 and the second clamp 22, the first clamp 21 and the second clamp 22 firmly install the sealing gasket 25 between the circular through hole and the pipe to be connected, improving the sealing performance and preventing liquid or gas from flowing out at the interface.

[0044] Please see Figure 4 In some embodiments, in conjunction with the second aspect, the first connecting portion 211 is provided with a through groove 212 and a circular hole 213. The circular hole 213 is provided on the first connecting portion 211, and the bottom of the circular hole 213 forms a supporting surface 214. The through groove 212 vertically penetrates the first connecting portion 211 and the through groove 212 penetrates the circular hole 213.

The head of the bolt 231 is provided with a pin hole 232, and the bolt 231 is threadedly connected to the anti-theft nut 1. The pin 233 passes through the pin hole 232 in the head of the bolt 231, and both ends of the pin 233 pass through two second circular holes 223 respectively.

[0047] First, the head of bolt 231 is placed between the gaps of the two extensions 222. Then, pin 233 passes through the two second round holes 223 and the pin-connecting hole 232 on the head of bolt 231, connecting bolt 231 to the second connecting seat. After the pin connection is completed, the screw (the shaft of bolt 231) is placed in the through groove 212 and threadedly connected to the anti-theft nut 1. The anti-theft nut 1 is tightened to the screw, and the bottom of the anti-theft nut 1 (the bottom of the clamping part 12) connects to the supporting surface 214, thereby connecting the first clamp 21 and the second clamp 22 into one unit.

[0048] Based on the above embodiments, the outer surfaces of the first clamp 21 and the second clamp 22 are provided with a plurality of reinforcing ribs 24, which improves the strength of the first clamp 21 and the second clamp 22.

[0049] Please see Figure 8 and Figure 9 The pipeline conveying device includes a drain pipe 3 in addition to the connecting clamp 2. The drain pipe 3 has a connector 31 at both ends. The connector 31 is connected to the pipe body of the drain pipe 3. The outer periphery of the connector 31 is provided with an annular groove 32. The annular groove 32 is used to limit the sealing gasket 25 during the connection with the connecting clamp 2.

[0050] Please see Figure 9 and Figure 10 Furthermore, the two ends of the drain pipe 3 are provided with annular receiving grooves 33, so that the end of the drain pipe 3 forms a stepped structure, which facilitates the connection of the connector 31 to the end of the drain pipe 3.

[0051] Furthermore, the drainage pipe 3 includes an inner layer, an outer layer, a wire mesh layer, and an adhesive layer. The wire mesh layer is located between the inner and outer layers, and the adhesive layer is used to bond the inner layer, outer layer, and wire mesh layer together. The drainage pipe 3 is a composite structure, which features high strength, corrosion resistance, and easy handling.

[0052] Specifically, both the inner and outer layers are made of polyethylene.
