Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated pipes, and particularly relates to a splicable corrugated pipe. Background Technique

[0002] A corrugated pipe refers to a tubular elastic sensitive element formed by connecting foldable corrugated sheets along the folding and telescopic direction. Corrugated pipes are widely used in instruments and meters. Their main purpose is to serve as a measuring element of a pressure measuring instrument, converting pressure into displacement or force.

[0003] At present, when installing and using a corrugated pipe, generally, the flat ends of two corrugated pipes are butted, and clamps and screws are used for locking on the outside. On the one hand, the contact area of the flat end face splicing of the corrugated pipe is small, resulting in general tightness of fitting. Moreover, during the butting process of the flat end faces of the two corrugated pipes, there is no positioning indication, which easily leads to misalignment and great difficulty in accurate butting. And accurate butting requires frequent debugging, which will consume a long time. On the other hand, the splicing and locking of the corrugated pipe are generally achieved by screws. The disassembly and assembly work of multiple screws is rather cumbersome, and the disassembly and assembly of screws both require the participation of a screwdriver tool, bringing the trouble of having to carry tools for disassembly and assembly.

[0004] Therefore, a splicable corrugated pipe is needed to solve the problems in the prior art that the contact area of the flat end face splicing of the corrugated pipe is small, resulting in general tightness of fitting, and the splicing using multiple screws for locking will lead to cumbersome disassembly and assembly processes and the necessity of carrying disassembly and assembly tools.

[0023] The following further describes the present utility model in combination with embodiments.

[0024] Please refer to Figures 1-4 , the present utility model provides a splicable corrugated pipe, including a first corrugated pipe 1 and a second corrugated pipe 2. The second corrugated pipe 2 is arranged on one side of the first corrugated pipe 1. A second engaging tooth 17 is arranged on one end face of the first corrugated pipe 1, and a first engaging tooth 16 is arranged at one end of the second corrugated pipe 2. A splicing combination mechanism is arranged between the first corrugated pipe 1 and the second corrugated pipe 2. The splicing combination mechanism includes a splicing female seat 3, a splicing male seat 4, a combined sliding column 5, a positioning round block 6 and an anti-torsion sliding strip 10. The splicing female seat 3 is sleeved and fixed on the outer surface of the first corrugated pipe 1. The splicing male seat 4 is arranged on one side of the splicing female seat 3. The combined sliding column 5 is fixed on the end face of the splicing male seat 4 close to the splicing female seat 3. The positioning round block 6 is fixed at the end of the combined sliding column 5 away from the splicing male seat 4. An anti-torsion sliding strip 10 is arranged between the splicing female seat 3 and the splicing male seat 4.

[0025] Furthermore, as shown in Figure 1 , Figure 2 and Figure 3As shown, it is worth specifically stating that the first meshing tooth 16 is meshingly connected to the second meshing tooth 17, and docking tooth grooves are provided between adjacent teeth of the first meshing tooth 16 and the second meshing tooth 17.

[0026] Furthermore, as shown in Figure 3 it is worth specifically stating that a disassembly and assembly opening 7 is provided on one end face of the splicing female seat 3 close to the splicing male seat 4, and an adjustment sliding groove 8 is provided on one end face of the splicing female seat 3, and the adjustment sliding groove 8 communicates with the disassembly and assembly opening 7.

[0027] The working process of this solution is as follows: When splicing two sections of corrugated pipes, the first meshing tooth 16 of the second corrugated pipe 2 is aligned with the second meshing tooth 17 of the first corrugated pipe 1 for docking. The teeth of the first meshing tooth 16 and the second meshing tooth 17 are tightly meshed with the tooth grooves, which can increase the contact area of the splicing of the first corrugated pipe 1 and the second corrugated pipe 2 to improve the tightness of the end face fitting. At the same time, the meshing method of tooth with tooth improves the poor accuracy of the butt joint of the flat end face of the traditional corrugated pipe and the difficult situation of accurate butt joint.

[0028] According to the above working process, it can be known that: The teeth of the first meshing tooth 16 and the second meshing tooth 17 are tightly meshed with the tooth grooves, which can increase the contact area of the splicing of the first corrugated pipe 1 and the second corrugated pipe 2 to improve the tightness of the end face fitting. At the same time, the meshing method of tooth with tooth improves the poor accuracy of the butt joint of the flat end face of the traditional corrugated pipe and the difficult situation of accurate butt joint.

[0029] Furthermore, as shown in Figure 1 、 Figure 2 and Figure 4 it is worth specifically stating that an observation notch 11 is provided on the rear end face of the splicing female seat 3. The combined sliding column 5 is slidably connected to the adjustment sliding groove 8 of the splicing female seat 3. When the first meshing tooth 16 and the second meshing tooth 17 are accurately docked, the positioning round block 6 enters along the disassembly and assembly opening 7 of the splicing female seat 3, and then the splicing male seat 4 is rotated along the second corrugated pipe 2, so that the combined sliding column 5 rotates away from the position where the disassembly and assembly opening 7 is located along the adjustment sliding groove 8 until the docking sliding rail 9 on the splicing male seat 4 is accurately docked with the docking sliding rail 9 on the splicing female seat 3 again. Finally, the anti-torsion sliding bar 10 is slid into the docking sliding rails 9 of the splicing female seat 3 and the splicing male seat 4 to lock the torsion of the splicing male seat 4. During this process, the axial separation movement of the first corrugated pipe 1 and the second corrugated pipe 2 can be restricted. At the same time, the accurate splicing of the first meshing tooth 16 and the second meshing tooth 17 can also restrict the rotational movement of the first corrugated pipe 1 and the second corrugated pipe 2 along the axis. In this way, the convenient combination of the first corrugated pipe 1 and the second corrugated pipe 2 can be realized, and the participation of screws is omitted, which is beneficial to the rapid disassembly without tools in the future.

[0030] Furthermore, as shown in Figure 4As shown, it is worth specifically stating that the positioning circular block 6 matches the disassembly and assembly opening 7 of the splicing female seat 3, and the positioning circular block 6 is slidably connected in the inner cavity of the splicing female seat 3.

[0031] Furthermore, as Figure 1 shown, it is worth specifically stating that a fixed sleeve opening 12 is provided inside the splicing female seat 3, and a rotating sleeve opening 13 is provided inside the splicing male seat 4.

[0032] Furthermore, as Figure 1 shown, it is worth specifically stating that the first corrugated pipe 1 is fixedly penetrated through the fixed sleeve opening 12 of the splicing female seat 3, a rotating convex ring 14 is fixed on the inner wall of the splicing male seat 4, a receiving rotating ring groove 15 is formed on the surface of the second corrugated pipe 2, and the splicing male seat 4 is rotatably connected to the surface of the second corrugated pipe 2.

[0033] Furthermore, as Figure 1 shown, it is worth specifically stating that docking slide rails 9 are provided on the sides of both the splicing female seat 3 and the splicing male seat 4, and the anti-torsion slide bar 10 is slidably embedded in the docking slide rails 9 where the splicing female seat 3 and the splicing male seat 4 are docked.

[0034] In summary: The teeth of the first meshing tooth 16 and the second meshing tooth 17 are closely meshed, which can increase the contact area of the splicing of the first corrugated pipe 1 and the second corrugated pipe 2 so as to improve the tightness of the end face fitting. At the same time, the meshing manner of the teeth improves the poor accuracy of the butt joint of the flat end faces of the traditional corrugated pipes and the difficult situation of accurate butt joint; it can limit the axial separation movement of the first corrugated pipe 1 and the second corrugated pipe 2. At the same time, the accurate splicing of the first meshing tooth 16 and the second meshing tooth 17 can also limit the rotational movement of the first corrugated pipe 1 and the second corrugated pipe 2 along the axis. In this way, the convenient combination of the first corrugated pipe 1 and the second corrugated pipe 2 can be realized, and the participation of screws is omitted, which is beneficial to the quick disassembly without tools in the follow-up.
