Abstract

The utility model relates to a fixed plastic joint for a drainage pipe, which is formed by plastic injection molding into integration, and is composed of an upper supporting port, a lower inserting part and two fixing ears. Screw holes with the specification of-phi 6 mm are arranged on the two fixing ears. In the course of installation, the method of upper supporting and lower inserting is adopted. In other words, the upper supporting port of the joint is sheathed upwards on the exterior of the drainage pipe on the top part. The edge of the top port of the lower inserting part is used to support the upper drainage pipe. Simultaneously, the lower inserting part of the joint is inserted downwards to the lower drainage pipe. Then, screws fix the joint and the drainage pipe on a wall through the screw holes on the two fixing ears, which is very stable and eliminates the phenomenon that the drainage pipe glides and drops off.

Description

Fixed plastic joint for drainage pipe

The utility model relates to a kind of piecing devices of used for building exterior wall leader, particularly a kind of fixed Plastic down pipe joint.

At present, China's used for building exterior wall leader substantially all is that glass fiber reinforced plastic is made, and the connection between the leader all is plug-type, is about to upper downpipe insert among the lower downpipe, is fixed on the wall with iron sheet card article or glass fiber reinforced plastic card article in its outside then.And do not have special piecing devices to connect, and original connection and fixing means, card article how can occur gets rusty, becomes flexible, and causes leader to glide, come off, and causes sewage outflow pollution wall in the pipe.

The purpose of this utility model provides a kind of fixed Plastic down pipe joint, promptly by joint up and down two-part leader fuse and fixing on the wall, overcome the disadvantage of original leader junction.

The purpose of this utility model is achieved in that it is one that joint adopts the plastic injection piece injection mo(u)lding, joint is by the pop-up mouth, lower inserting part and two fixedly ear constitute one, the bore of its pop-up mouth is slightly larger than the leader bore, the bore of lower inserting part is slightly less than the bore of leader, when mounted promptly, the pop-up mouth of joint upwards is enclosed within on the leader of top, the bottom of its leader is just in time held by the mouth edge, top of joint lower inserting part; The lower inserting part of joint inserts downwards in the leader of bottom.It not only can form one with the Plastic down pipe that forms a complete production network, and use also can match with original fiberglass reinforced plastics downpipe.Two of joint fixedly ear be located at the both sides of joint pop-up mouth respectively, the screw of a φ 6mm is respectively arranged on the ear, its objective is that available screw is fixing on the wall with joint and leader after joint and leader connect.Therefore, it has not only played the effect that connects leader, has also played the fixing effect of card article simultaneously.The phenomenon that avoided the leader downslide, comes off.

The utility model is described in further detail below in conjunction with accompanying drawing:

Among the figure: 1, pop-up mouth, 2, fixing ear, 3, screw, 4, lower inserting part.

It is one that joint adopts the plastic injection piece injection mo(u)lding, and joint is by pop-up mouth (1), lower inserting part (4) and pop-up mouth (1) both sides two fixedly ear (2) constitute one, two fixedly ear be provided with the screw (3) of a φ 6mm.During installation, the method that adopts pop-up to insert down, the bottom that the pop-up mouth (1) of joint upwards is enclosed within its leader of the outside of top leader is just in time held by the mouth edge, top of lower inserting part (4), lower inserting part (4) with joint inserts downwards in the leader of bottom simultaneously, when joint and after two-part leader connects up and down, again with screw by two fixedly on the exterior wall that is fixed on building that joint and leader is highly stable of two screws (3) on the ear (2), and because employing is the method for inserting under the pop-up, also just eliminated the leader downslide, the phenomenon that comes off, it has not only played the effect that connects leader simultaneously, also played the fixing effect of original card article, and attractive in appearance, firm, durable.

Claims

1, a kind of leader joint of used for building exterior wall, it is characterized in that joint by pop-up mouth (1), lower inserting part (4) and two fixedly ear (2) injection mo(u)lding be one.

2, fixed Plastic down pipe joint according to claim 1 is characterized in that the bore of pop-up mouth is slightly larger than the bore of lower inserting part.

3, joint according to claim 1 is characterized in that: two fixedly ear be located at the both sides of pop-up mouth respectively, the screw of a φ 6mm is respectively arranged on two ears.
