[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example

[0025] like Figures 1 to 5 As shown, a connecting pipe for sewage treatment includes a first intermediate connecting pipe 10, a second intermediate connecting pipe 11 at the bottom of the first intermediate connecting pipe 10, and interface connecting pipes 12 symmetrically provided at both ends of the first intermediate connecting pipe 10. The outer wall of the interface connecting pipe 12 is provided with a connecting outer ring 13.

[0026] It should be noted that, in this embodiment, the top end of the first intermediate connecting pipe 10 is provided with a protrusion 101, and the other end of the top of the first intermediate connecting pipe 10 is provided with a groove 102; the inner walls of both ends of the first intermediate connecting pipe 10 are provided with a stop block 103; the second intermediate connecting pipe 11 has the same structure as the first intermediate connecting pipe 10, and is provided with a second protrusion 111, a second groove 112, a second stop block 113, and a second thread 114.

[0027] Among them, the protrusion 101 and the groove 102 are correspondingly set. The protrusion 101 and the groove 102 have the same shape. The protrusion 101 is embedded in the inner wall of the groove 102 and is in contact with and fits the inner wall of the groove 102. In actual use, if necessary, a rubber strip needs to be set at the bottom or outer wall of the groove 102 to increase the sealing performance.

[0028] Based on the same principle, protrusion 111 and groove 112 are also set accordingly; through the mutual cooperation of protrusion 101 and groove 102 and protrusion 111 and groove 112, the first intermediate connecting pipe 10 and the second intermediate connecting pipe 11 are made to cooperate together to form a complete intermediate connecting pipe.

[0029] Similarly, the first stop 103 and the second stop 113 form a complete limiting ring, which has a complete annular inclined surface 15;

[0030] Further need to explain is, the annular inclined surface 15 and the tangent surface 122 of the top of the outer wall of the interface connecting pipe 12 correspond to set up, because the nature of the interface connecting pipe 12 and the strength limit of material, when the annular inclined surface 15 and the tangent surface 122 contact, the interface connecting pipe 12 deforms resistance, on the one hand, make the screwing of the connecting outer ring 13 be limited, on the other hand, the connection of the interface connecting pipe 12 and the second intermediate connecting pipe 11 and the first intermediate connecting pipe 10 is more stable.

[0031] The first intermediate connecting pipe 10 and the second intermediate connecting pipe 11 constitute a complete cavity 14;The cavity 14 can place filter pipe components in use, and the sewage of the connected pipeline is filtered once.

[0032] The outer wall of the first intermediate connecting pipe 10 is provided with a thread one 104, and the thread two 114 at both ends of the second intermediate connecting pipe 11 constitutes a complete annular thread, when connected with the internal thread 132 of the inner wall of the connecting outer ring 13, the limitation of the internal thread 132 can realize the limiting and fixing of both ends of the first intermediate connecting pipe 10 and the second intermediate connecting pipe 11, by continuously tightening the connecting outer ring 13, the first intermediate connecting pipe 10 and the second intermediate connecting pipe 11 will be fixed more stably.

[0033] The outer wall of the interface connecting pipe 12 is provided with a limiting ring 121, and the outer wall of the interface connecting pipe 12 is provided with a tangent surface 122. The limiting ring 121 and the clamping groove 131 provided at one end of the inner wall of the connecting outer ring 13 are correspondingly arranged, the clamping groove 131 is clamped on the outer wall of the limiting ring 121, so that the connecting outer ring 13 can rotate at any angle of the axial direction of the connecting outer ring 13, and the assembly and connection of the first intermediate connecting pipe 10 and the second intermediate connecting pipe 11 are realized.

[0034] The inner wall of the connecting outer ring 13 is provided with a clamping groove 131. The inner wall of the connecting outer ring 13 is also provided with an internal thread 132, and the internal thread 132 is correspondingly arranged with the thread one 104.

[0035] The working principle of the utility model is:

[0036] In the utility model, during assembly, the operator needs to place the filter component in the cavity 14 composed of the first intermediate connecting pipe 10 and the second intermediate connecting pipe 11 in advance, the convex block one 101 and the recess one 102 are correspondingly arranged, the convex block two 111 and the recess two 112 are also correspondingly arranged, and the first intermediate connecting pipe 10 and the second intermediate connecting pipe 11 are naturally limited and assembled together.

[0037] Among them, the convex block one 101 and the recess one 102 and the convex block two 111 and the recess two 112 increase the sealing performance by setting the rubber strip.

[0038] Subsequently, the end of the interface connecting pipe 12 without the inner cutting surface 122 is sleeved on the sewage pipe to be connected, or embedded on the sewage pipe to be connected, and the connection is reinforced by necessary glue, then the assembled first intermediate connecting pipe 10 and the second intermediate connecting pipe 11 are sleeved on the end of the interface connecting pipe 12 with the inner cutting surface 122, and the inner thread 132 is aligned and screwed, finally the first intermediate connecting pipe 10 and the second intermediate connecting pipe 11 are connected together at one end with the interface connecting pipe 12, and the other end is also connected and fixed based on the same principle;

[0039] Wherein, the outer wall of the interface connecting pipe 12 is provided with a limiting ring 121, and the top of the outer wall of the interface connecting pipe 12 is provided with an inner cutting surface 122. The limiting ring 121 and the inner wall of the connecting outer ring 13 are provided with a clamping groove 131 at one end, which are correspondingly arranged, and the clamping groove 131 is clamped on the outer wall of the limiting ring 121, so that the connecting outer ring 13 can rotate at any angle of the axial direction of the connecting outer ring 13, and the assembly and connection of the first intermediate connecting pipe 10 and the second intermediate connecting pipe 11 are facilitated.

[0040] When it is necessary to disassemble or maintain and replace the internal filtering components, the interface connecting pipe 12 is screwed to separate the first intermediate connecting pipe 10 and the second intermediate connecting pipe 11 from the interface connecting pipe 12 at one end, and the first intermediate connecting pipe 10 and the second intermediate connecting pipe 11 are separated from the interface connecting pipe 12 at the other end, so that the first intermediate connecting pipe 10 and the second intermediate connecting pipe 11 can be opened and replaced. The connecting pipe is convenient to connect and maintain.

[0041] The above embodiments only illustrate the technical idea of the utility model, and cannot limit the protection scope of the utility model. Any modification made on the basis of the technical scheme according to the technical idea of the utility model falls within the protection scope of the utility model.
