[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0025] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate directions or positions, and the relationship is based on the directions or positional relationships shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0027] 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.
[0028] Example 1
[0029] like Figure 1 and Figure 2 As shown, the skylight drainage pipe joint of this embodiment includes a connecting pipe composed of a first connecting head 11 and a second connecting head 12, and a water passage is provided in the connecting pipe. The structure is the same as that of the prior art, such as Figure 6As shown, the first connector 11 is connected to the skylight drain outlet 1, and the second connector 12 is connected to the drain pipe 3. The difference is that a support pipe 4 is arranged inside the drain pipe 3, and a rear clamp 5 cooperating with the support pipe 4 is arranged outside the second connector 12. A front clamp 6 is arranged outside the connection between the first connector 11 and the skylight drain outlet 1. When in use, the original drain pipe is pulled out from the skylight drain outlet 1, and the skylight drain outlet 1 is cleaned. The drain pipe is a consumable part, and the first place where it is damaged is the joint with the skylight drain outlet 1. Therefore, the damaged section is cut off, and the skylight drain pipe joint of this embodiment is used for connection. The first connector 11 is connected to the skylight drain outlet 1, and the second joint 12 is connected to the drain pipe 3 after cutting. Since the drain pipe will be shortened after cutting, in this embodiment, the total length of the connecting pipe ranges from 7 to 10 cm. The size of the water passage matches the size of the skylight drain pipe, which is a clearance fit. Usually, the diameter of the drain pipe is 1.2 cm, so the diameter of the water passage here is 1.248 cm.
[0030] In order to improve the structural strength of the connection end, the outer diameter of the first connection head 11 is larger than the outer diameter of the second connection head 12. That is, the thickness of the first connection head 11 is larger than the thickness of the second connection head 12, which can extend the service life and ensure its flexibility and facilitate bending.
[0031] A transition section 10 is disposed outside the first connector 11 and the second connector 12 .
[0032] The transition section 10 is a tapered structure, which facilitates the transition between the first connector 11 and the second connector 12 .
[0033] The connecting pipe is injection molded from PVC material.
[0034] Example 2
[0035] like Figure 5 As shown, an adhesive layer 13 is provided inside the first connector 11. In order to improve the sealing performance and connection strength, a waterproof adhesive material is coated on the skylight drain outlet 1 to form the adhesive layer 13 during installation.
[0036] Example 3
[0037] like Figures 3 to 5 As shown, a water-blocking spiral 14 is provided in the connecting pipe, and a protrusion is provided on the outside of the supporting pipe 4 to cooperate with the water-blocking spiral 14. The water-blocking spiral 14 in this embodiment is a spiral structure or a simple barb structure, which is selected according to the processing technology. The setting of the water-blocking spiral 14 combined with the fixing of the clamp helps to further seal and block water.
[0038] The utility model does not show the specific structure of the clamp, and a stainless steel elastic clamp, a stainless steel spiral clamp or other types of clamps may be used. In order to prevent the metal clamp from damaging the pipeline, an elastic ring may be provided in the clamp.
[0039] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
