Description

Drain pipe joint assembly

Technical Field

The utility model relates to a pipe fitting especially relates to a drain pipe joint subassembly.

Background

The existing injection-molded TPE joint has two forms: one is that the TPE connects does not have the bush, and the port department is the bellows, if mould plastics like this, appears the bellows easily and is crushed by the mould at the in-process of moulding plastics, leads to the product unqualified, simultaneously because do not have the reason of bush, whole joint all is soft, can appear connecting to bond on injection moulding equipment at the in-process of moulding plastics, needs the manual work to operate and extracts, can't realize automated production. The other type is that the lining is additionally arranged on the original basis, the connection between the corrugated pipe and the lining is realized, although automatic production can be realized, the inner diameter of the lining is inconsistent with that of the corrugated pipe, the lining sleeve is provided with salient points or stop points in the TPE joint, resistance is generated to further influence the flow of water, meanwhile, the corrugated pipe is not effectively improved, and the condition that the corrugated pipe is easily crushed by mold equipment is not improved. Therefore, it is necessary to design a drain pipe joint assembly which is not easy to crush the corrugated pipe and is convenient for automatic production

Disclosure of Invention

The utility model mainly solves the problems and provides a drain pipe joint component which is not easy to crush and is convenient for automatic production.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a drain pipe joint subassembly, includes that bellows and TPE connect, still includes the bush, the one end card of bellows in the outlet port that TPE connects, the outer wall of inner wall and bush that TPE connects between the rubber coating be connected, the one end rubber coating of bellows is on the outer wall of bush, the automated production of being convenient for.

As a preferable scheme of the scheme, the lining is arranged in the TPE joint, and the lining and the corrugated pipe are connected by adopting a flat stop. The inner liner sleeve can block water and influence flow if the inner end point of the TPE joint protrudes, so that the inner liner sleeve is adopted in the TPE joint.

As a preferable scheme of the scheme, the diameter of the corrugated pipe is consistent with that of the bushing, the lining of the bushing is level with the corrugated pipe, the bushing is consistent with the inner diameter of the corrugated pipe, no salient points or stop points exist, the inner diameter is increased, and water drainage is smooth.

As an optimal scheme of the scheme, the corrugated pipe is in contact with the lining, the flange surface is 5-20 mm wide, the flange surface and the corrugated pipe are in an integrated structure, the corrugated pipe is effectively improved in the condition that the corrugated pipe is crushed, and meanwhile firmness of the corrugated pipe and the joint is improved.

As a preferable scheme of the scheme, a closing-in is arranged at the water outlet hole of the lining. When rivers flowed from the bush, flow from the bellows centre, reduce rivers and bellows pipe wall impact contact, make the bellows more firm card on the TPE joint.

The utility model has the advantages that: the drain pipe joint assembly is characterized in that the lining is sleeved in through the TPE joint, the lining is connected with the corrugated pipe in a flat blocking mode, and then the drain pipe joint assembly is formed through integration of injection molding and rubber coating, so that the problems that the corrugated pipe is crushed in the injection molding process and automatic production cannot be achieved are solved.

Detailed Description

The technical solution of the present invention is further described below by way of examples and with reference to the accompanying drawings.

Example 1: please refer to fig. 1 and 2:

the utility model provides a drain pipe joint subassembly, connects 3 including bellows 1 and TPE, still includes bush 2, the one end card of bellows 1 in the apopore 32 that TPE connects 3, TPE connect between the inner wall of 3 and the outer wall of bush 2 the rubber coating be connected, the one end rubber coating of bellows 1 is connected on 2 outer wall of bush. When rivers got into the TPE and connect, rivers can strike the bush, extrude the bush to protected the bellows and be difficult for droing, made the card that bellows 1 is firm 3 in the TPE connects, the automated production of also being convenient for simultaneously.

The lining is sleeved in the TPE joint, the lining and the corrugated pipe are connected in a flat blocking mode, and then the drainage pipe joint set is formed through integration of injection molding and rubber coating, so that the corrugated pipe is prevented from being crushed in the injection molding process, and automatic production is realized.

The bush 2 connects 3 insides at TPE, and bush 2 adopts the flat fender hookup with bellows 1, and the bush 2 connects 3 interior termination point salients at TPE, can hinder water, influences the flow, so adopts bush 2 to connect 3 insides at TPE.

The diameter of the bellows 1 corresponds to the diameter of the liner 2. The inside lining and the bellows of bush are kept level, and the bush is unanimous with the bellows internal diameter, does not have the bump, and the internal diameter increase does not influence drainage flow, makes the unobstructed while such design of drainage just can effectively prevent that the bellows from being appeared by the condition that the mould crushd at the in-process of moulding plastics.

One section width that bellows 1 and bush 2 contacted is 5 ~ 20 mm's flange face, and flange face and bellows are the integral structure, have effectively improved the bellows and have increased the firmness of bellows and joint by the crushing condition simultaneously.

Example 2 please refer to fig. 3:

embodiment 2 is equipped with binding off 21 on the local bush 2 different with embodiment 1, and binding off 21's effect is when rivers flow from the bush, lets rivers flow out from the bellows in the middle of, reduces rivers and bellows pipe wall impact contact, makes the bellows more firm card on the TPE joint.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.

Although terms like pipes, joints and bushings are used more often herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed as being without limitation to any additional limitations that may be imposed by the spirit of the present invention.
