Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe joint technology, specifically a three-way corrugated pipe joint. Background Technology

[0002] A bellows is a tubular elastic sensing element made of foldable corrugated sheets connected along the folding and stretching direction. Bellows are widely used in instruments and meters.

[0003] In the prior art, such as the application with application number CN201520221789.3, the subject of which is "A Corrugated Pipe Fitting", the fitting includes a corrugated pipe fitting body, which is divided longitudinally into a corrugated pipe connection end and an external pipeline welding end. The corrugated pipe connection end is a circular port, and the inner diameter of the corrugated pipe connection end matches the outer diameter of the corrugated pipe to be connected. The inner diameter port of the corrugated pipe connection end is chamfered. The external pipeline welding end is also a circular port, and the inner diameter port of the external pipeline welding end is chamfered. The two chamfers are of the same specification. A flange is provided between the corrugated pipe connection end and the external pipeline welding end. The flange is provided with a threaded hole. The inner wall of the corrugated pipe fitting has an inwardly protruding ring between the corrugated pipe connection end and the external pipeline welding end, and the ring is chamfered on one side of the corrugated pipe connection end.

[0004] However, the existing bellows joints, which use a ring to connect to the bellows when fixing it, cannot match narrower bellows gaps and are not easy to fit the gaps of the bellows for secure fixing. Therefore, a three-way bellows joint needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a three-way corrugated pipe connector to solve the problems in the prior art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A tee bellows connector, the bellows connector comprising:

[0008] The Y-shaped body has joints fixed at both ends;

[0009] A rubber inner plug is provided inside the joint. One end of the rubber inner plug is fixed with a connecting block, and the other end is fixed with a triangular protrusion for fixing the bellows.

[0010] Furthermore, the Y-shaped body is fixedly provided with a fixing hole, and the fixing hole is provided with an internal thread for installation.

[0011] Furthermore, the connector is threaded with a clamping cap.

[0012] Furthermore, one end of the rubber inner plug is fixedly provided with an array of protrusions, and one end of the rubber inner plug is fixedly provided with a gasket, which engages with the protrusions.

[0013] Furthermore, the inner rubber plug is provided with an annular groove, and an adjusting washer is fixedly provided inside the inner rubber plug. The adjusting washer is fixed to the inner side of the connecting block, and a triangular protrusion is fixedly provided inside the adjusting washer.

[0014] Furthermore, the adjusting washer has a hollow groove inside.

[0015] The beneficial effects of this utility model are:

[0016] 1. The three-way corrugated pipe connector of this utility model uses a triangular protrusion to lock with the corrugated pipe. When fixing, the tip of the triangular protrusion is inserted into the gap of the corrugated pipe, which makes it easy to lock with corrugated pipes with different gap widths and easy to match different corrugated pipes.

[0017] 2. In actual use, the three-way corrugated pipe joint of this utility model connects the corrugated pipe through a rubber inner plug, and then uses a compression cap to squeeze the rubber inner plug to seal the gap between the corrugated pipe and the compression cap, thereby achieving the functions of waterproofing and sealing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] A type of tee bellows connector, such as Figure 1 As shown, the corrugated pipe connector includes a Y-shaped body 1. One end of the Y-shaped body 1 is provided with a connector 11, and the other end is also provided with two connectors 11. The interior of the Y-shaped body 1 is a hollow structure, so that the three connectors 11 are interconnected to meet the connection of the three corrugated pipes.

[0029] The Y-shaped main body 1 is fixedly provided with a fixing hole 12, and the fixing hole 12 is provided with an internal thread. The screw passes through the internal thread to connect with other structures, thereby installing and fixing the Y-shaped main body 1.

[0030] like Figure 2 As shown, a rubber inner plug 2 is installed inside the connector 11 of the Y-shaped body 1. A connecting block 21 is fixedly provided at one end of the rubber inner plug 2, and a triangular protrusion 22 is fixedly provided at the other end. The connecting block 21 contacts the bottom of the connector 11, and a tightening cap 3 is threadedly connected to the connector 11.

[0031] When the bellows is inserted into the rubber inner plug 2, the tightening cap 3 is then fitted onto the bellows and tightened onto the connector 11. The outer end of the tightening cap 3 will pressurize the outer end of the rubber inner plug 2, causing the triangular protrusion 22 to press inward. The triangular protrusion 22 is then engaged in the bellows groove of the bellows, fixing and sealing the bellows and effectively preventing water from overflowing.

[0032] Example 2:

[0033] like Figure 2 , Figure 3 As shown, one end of the rubber inner plug 2 is fixedly provided with an array of protrusions 24, and one end of the rubber inner plug 2 is fixedly provided with a gasket 23. The gasket 23 is engaged with the protrusions 24. An annular groove 26 is provided on the rubber inner plug 2, which can be used to install washers.

[0034] An adjusting washer 25 is fixedly installed inside the rubber inner plug 2. The adjusting washer 25 is fixedly installed on the inner side of the connecting block 21. A triangular protrusion 22 is also fixedly installed on the inner side of the adjusting washer 25 to restrict the end of the bellows located inside the connector 11. The part that contacts the clamping cap 3 is then restricted and fixed by the triangular protrusion 22, providing a double seal and enhancing the waterproof effect.

[0035] A hollow groove 27 is provided inside the adjusting washer 25 to increase the flexibility and elasticity of the adjusting washer 25.

[0036] By inserting an adjusting washer 25 inside the rubber inner plug 2, the gap of the rubber inner plug 2 is reduced, thereby fixing the bellows that are smaller than the diameter of the rubber inner plug 2.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
