Currently, pipeline laying is done by directly burying the pipelines and connecting and laying them, so as to achieve the same purpose of connecting all pipelines. During pipeline laying, it is often necessary to connect multiple sections of pipelines. During the connection between pipelines, in order to tighten the connection to prevent accidental loosening, self-tapping screws, rivets or similar components are preferably used to tighten the connection points at the overlapping parts of the pipe walls.

The surfaces of the fixing ring and the connecting ring are provided with horizontal through holes, and fixing bolts are provided in the through holes. This pipeline connection structure can achieve a good sealing effect at the connection gap through the sealing ring, thereby avoiding water seepage at the pipeline connection. After the fixing ring of the water supply and drainage pipe and the connecting ring of the connecting pipe are connected by the fixing bolts, a fixing rod, a connecting convex ring and a limit block thereon are provided between the two to reinforce them, thereby strengthening the connection between the two, increasing the stability of the pipeline connection and ensuring the use effect.

[0004] After searching, there are many ways to connect existing pipes, the most common ones are: threaded connection, flange screw connection, rubber ring connection, glue connection, hot melt connection, etc. These connection methods cannot solve the problem of pipe connection very well, and cannot perfectly solve the problem of pipe disconnection and leakage.

[0005] Therefore, a double insurance anti-falling pipe is proposed to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a double-insurance anti-falling pipe, which has the advantages that the pipe connection is not easy to fall off or leak, and is easy to install and construct. It also solves the problem that the existing pipe connection structure is fixed with bolts during installation, and the installation steps are relatively cumbersome, time-consuming and labor-intensive, which increases the workload of the staff, has low installation efficiency of the pipe, and thus reduces the construction efficiency.

[0007] To achieve the above purpose, the utility model provides the following technical solutions: a double insurance anti-dropping pipe, comprising a small head end pipe and a flared head end pipe, one end of the flared head end pipe is fixedly connected to the flared head, and a connecting component is arranged between the flared head end and the small head end pipe;

[0008] The connecting assembly consists of a first annular clamping tooth, a second annular clamping tooth and a resistance wire, the first annular clamping tooth is fixedly connected to the outer wall of the small head end pipe, the second annular clamping tooth and the resistance wire are both fixedly connected to the inner wall of the expansion head, and the first annular clamping tooth and the second annular clamping tooth cooperate with each other.

[0009] Furthermore, the sizes of the pipe at the small end and the pipe at the expansion end are matched, and the outer wall of the pipe at the small end is matched with the inner wall of the expansion end.

[0010] Furthermore, the number of the first annular teeth and the second annular teeth are set to multiple groups, the multiple groups of the first annular teeth are evenly arranged and distributed along the outer wall of the small head end pipe, and the multiple groups of the second annular teeth are evenly arranged and distributed along the inner wall of the expansion head.

[0011] Furthermore, the resistance wire is distributed in a ring shape on the inner wall of the expansion mouth, and both ends of the resistance wire extend to the outside of the expansion mouth.

[0012] Furthermore, the first annular locking tooth is inclined along a side opposite to the direction of the expansion head, and the second annular locking tooth is inclined along a side in the same direction as the expansion head end pipe.

[0013] Compared with the prior art, the utility model provides a double insurance anti-falling pipeline, which has the following

[0014] Beneficial effects:

[0015] The double-insurance anti-falling pipe is connected to each other by the first annular clamping tooth and the second annular clamping tooth to avoid loosening, thereby realizing rapid fixation of the small head end pipe and the expansion head end pipe. At the same time, the resistance wire generates heat after being connected to the power supply, so that the small head end pipe around the resistance wire and the expansion head are hot-melted together to achieve double fixation with excellent fastening performance. At the same time, the small head end pipe and the expansion head end pipe are convenient to connect. It only needs to combine the small head of the small head end pipe with the expansion head and heat the resistance wire, so that the pipe connection is not easy to fall off and leak, which improves the performance and convenience of use of the pipe, and solves the problem that the existing pipe connection structure is fixed by bolts during installation, and the installation steps are relatively cumbersome, time-consuming and labor-intensive, which increases the workload of the staff, has low installation efficiency of the pipe, and thus reduces the construction efficiency.

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

[0022] See also Figure 1-4 A double-insurance anti-falling pipe in this embodiment includes a small head end pipe 1 and a flared head end pipe 2, one end of the flared head end pipe 2 is fixedly connected with a flared head 3, wherein the sizes of the small head end pipe 1 and the flared head end pipe 2 are adapted, the outer wall of the small head end pipe 1 is adapted to the inner wall of the flared head 3, and the flared head 3 is used to cooperate with the small head end pipe 1, which facilitates the rapid connection between the small head end pipe 1 and the flared head end pipe 2.

[0023] In this embodiment, a connecting component is provided between the expansion head 3 and the small head end pipe 1, and the connecting component consists of a first annular clamping tooth 4, a second annular clamping tooth 5 and a resistance wire 6. The first annular clamping tooth 4 is fixedly connected to the outer wall of the small head end pipe 1, and the second annular clamping tooth 5 and the resistance wire 6 are both fixedly connected to the inner wall of the expansion head 3. The first annular clamping tooth 4 and the second annular clamping tooth 5 cooperate with each other, wherein the first annular clamping tooth 4 is inclined along the opposite direction of the expansion head 3, and the second annular clamping tooth 5 is inclined along the same direction of the expansion head end pipe 2.

[0024] It should be noted that the number of the first annular latch teeth 4 and the second annular latch teeth 5 are set to multiple groups, and the multiple groups of first annular latch teeth 4 are evenly arranged and distributed along the outer wall of the small head end pipe 1, and the multiple groups of second annular latch teeth 5 are evenly arranged and distributed along the inner wall of the expansion head 3. When the small head end pipe 1 is combined with the expansion head 3, the cooperation of the first annular latch teeth 4 and the second annular latch teeth 5 can realize the rapid fixation of the small head end pipe 1 and the expansion head 3, so that the small head end pipe 1 and the expansion head end pipe 2 can be quickly installed together. At the same time, under the mutual clamping action of the first annular latch teeth 4 and the second annular latch teeth 5, the small head end pipe 1 and the expansion head 3 will not be separated, thereby achieving a good anti-separation effect.

[0025] It should be noted that the resistance wire 6 is distributed in a ring shape on the inner wall of the expansion head 3, and both ends of the resistance wire 6 extend to the outside of the expansion head 3. During the actual installation process, both ends of the resistance wire 6 extend outward along the port of the expansion head 3. When the small head end pipe 1 is connected to the expansion head 3, both ends of the resistance wire 6 are exposed 1-2CM outside the expansion head 3, so that the resistance wire 6 can be easily connected to an external power supply. When the small head end pipe 1 is combined with the expansion head 3, the resistance wire 6 is connected to the power supply to generate heat, thereby heat-melting the small head end pipe 1 and the expansion head 3 around the resistance wire 6 together, thereby achieving further fixation, and the fixing effect is good.

[0026] The working principle of the above embodiment is:

[0027] When the utility model is in use, the small head end pipe 1 is connected to the expansion head 3. After the two are connected, the first annular clamping tooth 4 and the second annular clamping tooth 5 are clamped with each other to prevent loosening. Subsequently, the resistance wire 6 is connected to the power supply to generate heat, so that the small head end pipe 1 around the resistance wire 6 and the expansion head 3 are heat-fused together to achieve double fixation, thereby realizing the quick connection of the small head end pipe 1 and the expansion head end pipe 2.
