Description

Connectors that can be firmly connected to fluid pipelines

This creation is related to a connector, especially a connector that can firmly connect a fluid pipeline.

Generally, pipelines used to transport fluids such as rubber or plastic pipes must be equipped with a connector to connect a device or another pipeline. A pipeline will be cut to an appropriate length according to actual needs, and then assembled. The joint is at one end of the pipeline.

Please refer to the conventional connector in FIG. 10, which puts one end of a tube 91 such as a rubber tube or a plastic tube inside a metal sleeve 92, and then puts one end of a hollow cylindrical insert 93 inside the tube 91 , And then apply a tightening pressure to the metal sleeve 92 with a machine or a hydraulic machine, so that the tube 91 is tightly clamped between the metal sleeve 92 and the insert 93, and then, A connecting portion 931 provided at the other end of the insert 93 is like an external thread to connect the internal thread of the other connector.

Please refer to another conventional connector of FIG. 11. The difference from FIG. 10 is that the connecting portion 931 provided at the other end of the insert 93 is set as a nut, and one end of the nut is pivotally connected to the insert 93 to connect to the other connector. External thread of the connector.

The aforementioned conventional connector needs to be equipped with a mechanical device or a hydraulic mechanical device to have sufficient tightening pressure to apply the metal sleeve 92 to achieve a water-tight or air-tight effect.

For the aforementioned conventional connector, due to the connection strength problem of the plug-in 93 connecting the tube body 91 or the tolerance of the tightening machinery and equipment, in quality control, a full inspection must be done to ensure that the plug-in 93 and The tube body 91 is watertight or airtight, which is not only laborious and time-consuming, but also the tightening process will also reduce the flow passage space of the insert 93.

Furthermore, the inventor of the present invention has an improved structure in which an annular body extends in the transverse direction on the inner side surface of one end of the metal sleeve 92, so that the outer end surface of the tube body 91 can abut against the side surface of the annular body. The inner surface is further provided with an internal thread, and a triangular-shaped external thread is provided at one end of the insert 93. With the internal thread and the external thread, a wrench is used to rotate the insert 93, and the insert 93 can be guided more easily. Into the inside of the tube body 91, the external thread of the insert 93 is used to engage and bite the inner surface of the tube 91; generally speaking, if the inner diameter of the tube 91 is 6.5 mm, the outer thread of the insert 93 has an outer diameter It must be about 9.6 mm to achieve the effect of interlocking and occluding to be watertight or airtight. The material for interlocking and occluding the tube body 91 is usually no greater than 0.5 mm, and the tensile strength of the insert 93 is about 60 kg.

However, with the improved structure of the metal sleeve 92 with internal threads and the plug 93 with external threads, the connection strength of the plug 93 when inserting and engaging the pipe body 91 still does not reach the ideal resistance strength. In addition, the plug When the triangular external thread of 93 enters the pipe body 91, eccentricity often occurs, resulting in undesirable engagement and engagement.

The main purpose of this creation is to provide a connector that can firmly connect fluid pipelines, which can be assembled into a tube or a device instantly and conveniently.

The secondary purpose of this creation is to provide a connector that can firmly connect the fluid pipeline, which can easily achieve the effect of watertight or airtight.

Another purpose of this creation is to provide a connector that can firmly connect fluid pipelines, which can reduce assembly costs.

The reason is that in order to achieve the aforementioned purpose, this creation is to provide a connector that can firmly connect the fluid pipeline, which at least includes an inner sleeve seat, the inner sleeve seat is a cylindrical body with a channel, and its two ends are defined separately It is a first end and a second end. The outer surface of the inner sleeve seat is provided with a guide part, an attachment part, a leak-proof part and a connecting part in sequence from the first end to the second end; The first end is inserted into the inside of one end of a tube body through the guide part; the attachment part is a spiral concave groove provided on the outside of the inner sleeve seat for attaching to the inner side of the tube; the leak-proof part is located at one end of the tube body and Between the connecting parts, it is used to close the opening of the pipe body to prevent leakage of the fluid in the pipe body; the connecting part is arranged between the leak-proof part and the second end of the inner sleeve seat and is exposed to the pipe body, and the connecting part is used to connect Another connection part of another connection head.

The connector disclosed by this creation can be firmly connected to the fluid pipeline, wherein the inner surface of one end of the outer sleeve 20 extends in the transverse direction with a ring 22, so that the outer end surface of the tube 15 It can abut against the side surface of the ring body 22 to have better assembly structure strength and assembly positioning.

Please refer to FIG. 4 for the second embodiment of the present creation. The connector disclosed in the present creation can firmly connect the fluid pipeline, wherein the other side of the attachment portion 14 does not extend into a columnar body toward the second end 13 , But a leak-proof washer is put on to form the leak-proof portion 16 to close the opening of the tube body 15.

Please refer to Figures 5 to 7 for the third embodiment of the present creation. The connector disclosed in the present creation can firmly connect the fluid pipeline. One end of the connecting portion 18 is pivotally connected to the inner sleeve 10, the other end of the connecting portion 18 is provided with an internal thread for connecting with another connector, and the other connecting portion of the other connector can be set as an external thread; In the third embodiment, the connecting portion 18 is configured as a nut.

Please refer to Figures 5 and 6 again. The connector disclosed by this creation can be firmly connected to the fluid pipeline. The creation can be assembled on the tube body 15 instantly and conveniently by applying a force on the hexagonal outline 32 by an Allen key.

Please refer to FIG. 8. If the third embodiment of the present creation does not design the hexagonal outline 32, the present creation can be equipped with a screw 17 for locking the connecting portion 18, and then linking the inner sleeve seat 10 to instantly And it is easily assembled on the tube body 15.

Please refer to FIG. 9 for the fourth embodiment of the present creation. If the third embodiment of the present creation does not design the hexagonal outline 32, the inner sleeve 10 is located between the leak-proof portion 16 and the connecting portion 18 A hexagonal body 62 extends outside, and the present creation can be assembled to the tube body 15 instantly and conveniently by applying a wrench to the hexagonal body 62.

In this creation, the spiral concave groove of the attachment part 14 can be designed as a trapezoidal thread or a rectangular thread, which greatly strengthens the connection strength of the inner sleeve seat 10 and the inner surface of the tube body 15. The material for the seat 10 to engage and engage the tube body 15 can reach 0.75~1.0mm, and the tensile strength of the inner sleeve seat 10 is about 120~200kg, making this creation almost or completely water-tight or air-tight, and, As long as the outer diameter of the spiral concave groove of the inner sleeve 10 is 8 mm to penetrate the tube 15 with an inner diameter of 6.5 mm, the present invention can achieve the aforementioned effects. On the other hand, the spiral shape of the inner sleeve 10 When the concave groove is inserted into the tube body 15, the inner sleeve seat 10 has the function of self-correction and does not cause eccentricity.
