Detailed Description

The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.

As shown in fig. 1-7, the drainage pipe for municipal roads structurally comprises a pipe body 11, a connecting outer pipe 1 sleeved on the pipe body 11 at 2 sections, an intermediate ring unit 2 arranged on the inner ring surface of the connecting outer pipe 1 and used for sealing the joint of the pipe body 11 at 2 sections, a fixed orifice unit 3 arranged on the outer ring surface of the pipe body 11, fastening hoops 4 arranged on all the fixed orifice units 3 of the pipe body 11 at a single section, and a screw joint unit 5 arranged on the connecting outer pipe 1 and used for fastening the fixed orifice unit 3.

In this embodiment, the connecting outer pipe 1, the intermediate ring unit 2, the fixed orifice unit 3, the fastening collar 4, and the screw unit 5 constitute the main body of the connection structure of the drain pipe. The thickness of each of the 2 sections of the pipe bodies 11 is not required to be consistent, which is the greatest advantage of the connecting structure, and the practicability of the connecting structure can be greatly improved.

Specifically, the principle of this connection structure is:

1. the pipe body 11 of the 2 sections can be fully and properly pressed on the middle ring unit 2 by means of the fastening force of the fixed orifice unit 3 and the screw connector unit 5 in the length direction of the pipeline, so that the connecting structure is ensured to have full waterproof sealing performance;

2. at least 2 pairs of screw-joint units 5 are arranged on the 2 sections of pipe bodies 11, so that the 2 sections of pipe bodies 11 are difficult to radially misplace;

3. the fastening hoop 4 ensures that the fixed orifice unit 3 installed later can be stably installed on the pipe body 11, so that the fixed orifice unit 3 is not easy to slide in the circumferential direction and shift in the length direction.

The main body of the intermediate ring unit 2 and the connecting outer tube 1 are made of hard plastics, so that sufficient hardness is ensured, and the intermediate ring unit 2 is prevented from being flattened and crushed by the 2 sections of the tube body 11.

In addition, the fixed orifice unit 3 is made of a material including a hard structure and an elastic structure, the former is fully clamped with the screw connector unit 5, and the latter ensures that a sufficient static friction force is provided on the outer ring surface of the pipe body 11.

Finally, the fastening collar 4 is designed to ensure that the static friction force is sufficiently high, and the fixed orifice unit 3 can be fixed to the pipe body 11 even if the screw unit 5 is still pulling the fixed orifice unit 3.

A sealing ring 6 is also arranged between the connecting outer tube 1 and the tube body 11.

In this embodiment, the number of the sealing rings 6 is 2, and the sealing rings 6 are respectively disposed on two sides of the intermediate ring unit 2, and the respective sizes of the 2 sealing rings 6 do not need to be identical, and only the inner ring surface of the connecting outer tube 1 and the outer ring surface of the tube body 11 need to be sealed and waterproof appropriately.

In addition, the sealing effect at the sealing ring 6 is a rear end sealing, and the front end is sealed between the middle ring unit 2 and the end face of the pipe body 11.

The inner ring surface of the connecting outer tube 1 is also provided with an annular groove 7 for clamping and fixing the sealing ring 6.

In this embodiment, since the size of the seal ring 6 is not unique, the annular groove 7 may be appropriately engaged to fix the seal ring 6, but the size of the seal ring 6 is not ensured to be consistent and the seal ring is tightly screwed.

The intermediate ring unit 2 includes a support ring 201 provided on the inner circumferential surface of the connecting outer tube 1, and annular elastic rings 202 provided on both side surfaces of the support ring 201, respectively.

In this embodiment, the material of the supporting ring 201 is hard plastic, and the material of the annular elastic ring 202 is common elastic rubber, which are adhered and fixed.

The number of the annular elastic rings 202 on one side is 4-10, and the annular elastic rings and the supporting ring 201 are in a concentric circle position relationship.

In this embodiment, the plurality of annular elastic rings 202, which are uniformly spaced from each other and are disposed in concentric circle positions, have at least the following two functions:

1. ensuring that the end sealing effect of the thick or thin pipe body 11 can be obtained on the supporting circular ring 201;

2. when the sealing ring 6 is used, the annular elastic ring 202 can be used as an alignment mark for centering the pipe body 11 in the connecting outer pipe 1, so that the whole sealing ring 6 is uniformly pressed everywhere, otherwise, the sealing performance of the sealing ring 6 is greatly reduced.

When the sealing ring 6 is not in use, the tube 11 may not be aligned with the annular elastic ring 202, because the fastening action on the fixed orifice unit 3 has a certain radial tolerance.

The fixed orifice unit 3 includes an elastic plate 301 provided on the outer circumferential surface of the pipe body 11, a bottom plate 302 provided on the elastic plate 301, a radial plate 303 provided on the bottom plate 302, and a rectangular opening 304 provided on the radial plate 303 for inserting the screw unit 5.

In this embodiment, the elastic plate 301 is made of normal rubber, and the base plate 302 and the radial plate 303 are integrally formed, and the elastic plate is made of plastic or metal with relatively high hardness.

The fixed orifice unit 3 further includes a catching groove 305 provided on the base plate 302 for catching the fastening collar 4.

In this embodiment, the specific mounting position of the single fixed orifice unit 3 on the pipe body 11 is not required, and on the premise that the fastening hoop 4 is not twisted, all the clamping grooves 305 are guaranteed to be fully clamped with the fastening hoop 4.

In other words, as shown in fig. 1, the circumferential installation angle of the fixed orifice unit 3 is determined by the screw unit 5, and the left and right positions of the fixed orifice unit 3 may be optional, so long as it is ensured that all the fixed orifice units 3 on one side are aligned left and right.

The fixed orifice unit 3 further includes side diagonal draw plates 306 provided on the base plate 302 and the radial plate 303.

In this embodiment, the term "side" refers to the fact that on the radial plate 303, the rectangular opening 304 is centered and the side inclined plate 306 is aside, so as to avoid the position of the side inclined plate 306 interfering with the insertion action of the screw unit 5.

In addition, the oblique-pulling reinforcement effect of the side oblique-pulling plate 306 ensures that the screw-on unit 5 can be screwed down more tightly, and finally the screw-on unit is embodied on the supporting ring 201, namely, the sealing waterproof performance is improved.

The screw unit 5 includes a screw 501 provided on the connection outer tube 1 and inserted into the rectangular opening 304, and a nut 502 provided on the screw 501 and used for fastening the radial plate 303.

In this embodiment, the screw units 5 on two sides are independent of each other, and the number and positions of the screw units are not corresponding, so that the screw units 5 on the same side and the fixed orifice unit 3 are accurately inserted and fully fastened.

Wherein the screw 501 is fixedly connected to the connecting outer tube 1, and the nut 502 is used for directly tightening the radial plate 303.

And 2-3 nuts 502 are arranged on each screw 501.

In this embodiment, the nuts 502 are stacked, so that the screw 501 and the nuts 502 after being fastened are more stable and are not easy to loosen, which is reflected on the drainage pipeline, and the effect is that the joint of the 2 sections of the pipe body 11 is stable in position and fully sealed.

The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
