Abstract
The utility model discloses a plastic socket connector for a drain pipe, which is characterized by comprising a tubular wall surface; bulges are formed on the inner side of the wall surface; and at least two expansive water stop strips are respectively mounted between the bulges. The utility model has the advantages of easy manufacture and strong applicability and is applicable to the drain pipe (including a cement pipe) with a smooth surface. The plastic socket connector can be directly and fixedly mounted at one end of the plastic drain pipe in a factory; and another plastic drain pipe is only required to be inserted in the plastic socket connector when being assembled on the site. The plastic socket connector has simple and efficient assembly process, good sealing effect at the connection and long service life.
Description
Technical field
The utility model relates to municipal drainage pipe field, especially for the waste pipe plastics bell and spigot joint that connects waste pipe.
Background technique
Mostly existing plastic drain-pipe is when connecting to connect by thermal shrinkable sleeve or Electric thermal smelting belt, such Placement need be provided with heating plant at the construction field (site), the problem of leaking appears in operation inconvenience in the work progress, and after long-time use the, heat-shrink tube joint easily.
The model utility content
The purpose of this utility model is: provide a kind of waste pipe plastics bell and spigot joint easy to connect, that quality of connection is good of using at the deficiencies in the prior art.
The technical solution of the utility model is:
The bell and spigot joint of a kind of waste pipe plastics is characterized in that: comprise the wall of tubulose, the wall inboard has projection, has at least two expansion waterstops to be installed in respectively between the adjacent projection.
Supplementary technology scheme of the present utility model is as follows:
Preferably, described projection is a hollow.
Preferably, described projection is extended formation wall interior annular projection, forms circular groove between the annular protrusion, and the expansion waterstop is installed in the circular groove.
Preferably, in the wall installed inside two expansion waterstops are arranged.
Preferably, in the wall installed inside four expansion waterstops are arranged.
The beneficial effects of the utility model are: joint is easily made; Joint adaptability is strong---and every surface is that the waste pipe (comprising cement pipe) of even surface is all applicable; For plastic drain-pipe, the plastics bell and spigot joint can directly be fixedly mounted on an end of plastic drain-pipe in factory, only another plastic drain-pipe need be inserted the plastics bell and spigot joint when assembling in the building site gets final product, the attachment portion of two waste pipes forms between two expansion waterstops and is tightly connected, whole assembling process is simply efficient, and the joint good sealing effect, long service life.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the sectional view of drain connection tube wall;
Fig. 2 is the schematic representation of the utility model waste pipe plastics bell and spigot joint specific embodiment:
Fig. 3 is the schematic representation of waste pipe plastics shown in Figure 2 bell and spigot joint when connecting waste pipe
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model 1, as shown in Figure 2, the bell and spigot joint of a kind of waste pipe plastics, the wall 2 that comprises tubulose, wall 2 inboards have the projection 3 of hollow, and expansion waterstop 4 is installed in respectively between the adjacent projection 3, and described expansion waterstop 4 has two.
This waste pipe plastics bell and spigot joint is used to connect plastic drain-pipe shown in Figure 11, Figure 1 shows that the tube wall sectional view of plastic drain-pipe 1, and the tube wall outside is a smooth flat, and the projection that the inboard has hollow is used to strengthen the ring stiffness and the intensity of pipe.
As shown in Figure 3, between two expansion waterstops of the attachment portion of two plastic tubes 1 in the bell and spigot joint of waste pipe plastics, form sealing relationship.
Above-mentioned waste pipe plastics bell and spigot joint can directly be fixedly mounted on an end of plastic drain-pipe 1 in factory, only another plastic drain-pipe 1 need be inserted the bell and spigot joint of waste pipe plastics when assembling in the building site and get final product.
In the above-described embodiments, described protruding 3 can extend formation wall interior annular projection, form the annular pass between the annular protrusion, and expansion waterstop 4 is installed in the annular pass.Also can four expansion waterstops 4 be arranged in order to strengthen sealing effect in the wall installed inside.
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
