Description

Structure of the joint

The invention relates to a joint structure, in particular to a joint connected between a pipeline and an instrument.

As shown in FIG. 3, a joint connected between the pipeline 8 and the meter 7 has a body 61 fixedly connected to the pipeline 8, wherein a valve member 62 is provided in the body 61, and the body The 61 peripheral has a nut 63 for connecting the meter, the meter 7 is locked into the nut 63 with a threaded connection end 71, and then abuts against the valve member 62, thereby sensing the pressure of the pipeline 8, and the nut 63 The meter 7 is tightly fixed with its thread.

However, during the process that the meter 7 is gradually locked into the nut 63, the initial friction between the meter 7 and the nut 63 is not large. The rotation of the meter 7 into the nut 63 does not affect the nut. Cap 63; however, after the meter 7 is screw-locked to contact the valve member 62, it must be tightened to continue screwing in. At this time, the friction between the meter 7 and the nut 63 increases. The nut 63 will be synchronously driven to rotate, so that the body 61 and the pipeline 8 connected to the body 61 are rotated together to change the direction in which the pipeline 8 extends, causing great environmental inconvenience. Based on this phenomenon, the construction staff must use a tool to keep the nut 63 fixed before they can continue to rotate the meter 7 until it is locked. This process is inconvenient, time-consuming, and physically demanding, so improvements are urgently needed.

In view of this, how to improve the above problems is the primary problem to be solved by the present invention.

The main object of the present invention is to provide a joint structure, which is composed of two connecting members pivoted, and the pivoting action of one is independent of the other, thereby preventing the rotation of one from affecting the other. Improve the convenience of installing this connector.

In order to achieve the foregoing object, the present invention provides a joint structure including: (1) a first connecting member having a head and a body connected to each other, the head being provided with a receiving chamber extending to the body, and A valve member is provided in the container chamber; a threaded section is provided in the container chamber for the head to be screwed to an external object; a first passage communicating with the container chamber is provided in the body; and a second connecting member is provided. The sleeve has a sleeve and a connecting portion for connecting an external pipe body; the sleeve surrounds a hollow chamber, and the connecting portion is provided with a second channel penetrating to the hollow chamber; the sleeve is sleeved on the first connecting piece The outer periphery of the body part can be pivoted relative to the body part, and a leakage stopper for closing the hollow chamber is provided between the sleeve and the body part.

In an embodiment, an operation member is fixedly connected to the end of the body portion for operating the first connection member to rotate.

In one embodiment, a ring groove is provided around the outer periphery of the body or around the inner periphery of the sleeve for the leakage stopper to be inserted.

In an embodiment, at least one expansion slot is provided around the outer periphery of the body or around the inner periphery of the sleeve within the enclosed area of the hollow chamber.

The above-mentioned objects and advantages of the present invention can be easily understood from the detailed description and accompanying drawings of selected embodiments below.

Please refer to FIGS. 1 and 2. The structure of the joint provided by the present invention includes a first connecting member 1 and a second connecting member 2, wherein the first connecting member 1 is connected to an external object. For example, the meter 4 or the pipe body, and the second connecting member 2 is connected to an external pipe body 5.

The first connecting member 1 has a head portion 11 and a body portion 12 connected to each other, wherein the body portion 12 protrudes from one side of the head portion 11. A container 13 extending to the body 12 is provided in the head 11 and a valve 3 is provided in the container 13; wherein the valve 3 is a device that can control the state of fluid flow in the conventional technology, It is screw-locked in the container 13. The accommodation chamber 13 is provided with a threaded section 131 at the end near the head 11 for locking the meter 4. A first channel 14 is formed on the peripheral side of the body portion 12 and penetrates to the containing room 13.

The second connecting piece 2 has a sleeve 21 and a connecting portion 22, wherein the connecting portion 22 protrudes from the peripheral side of the sleeve 21, so that the second connecting piece 2 forms a T shape; the connecting portion 22 It is tubular and used to connect a pipe body 5. The sleeve 21 surrounds a hollow chamber 23, and the connecting portion 22 is provided with a second channel 24 passing through the hollow chamber 23.

The inner diameter of the sleeve 21 is slightly larger than the outer diameter of the body 12, for the second connecting member 2 can be sleeved on the outer periphery of the body 12; in other words, the body 12 is worn. In the hollow chamber 23 of the sleeve 21, and its end protrudes from the hollow chamber 23. The hollow chamber 23 is closed at both ends with a leakage stopper 25, wherein the leakage stopper 25 is a rubber ring, which is arranged between the sleeve 21 and the body 12, and is surrounded by the body 12 A ring groove 15 is provided on the outer periphery or around the inner periphery of the sleeve 21 for the leakage stopper 25 to be embedded. In this embodiment, the ring groove 15 is provided on the outer periphery of the body 12.

With the combination of the above components, the pipe body 5 can communicate with the hollow chamber 23 through the second channel 24, and then communicate with the container 13 through the first channel 14, and communicate with the instrument 4 through the valve member 3. Based on this, the instrument 4 can measure the environmental state (such as pressure) of the pipe body 5. On the other hand, since the body 12 is disposed in the sleeve 21, the first connecting member 1 can be pivoted relative to the second connecting member 2; in this embodiment, the end of the body 12 is fixedly connected. An operating member 16 is used to conveniently control the body 12 and thereby rotate the first connecting member 1.

With the structure of the present invention, when connecting the pipe body 5 and the meter 4 using the present invention, the connecting portion 22 of the second connecting member 2 can be first fixedly connected to the pipe body 5, and then the meter 4 is extended into the first connecting member. The head section 11 of the head 11 is in the threaded section 131 of the inner chamber 13 and the first connecting member 1 is rotated by rotating the operating member 16 to thereby tighten the meter 4 on the first connecting member 1. In the above process, since the first connection member 1 can be pivoted relative to the second connection member 2, the rotation caused by the meter 4 being locked on the first connection member 1 will not affect the second connection member 2. Therefore, the pipe body 5 will not be displaced accordingly; further, the present invention can rotate the first connecting member 1 by rotating the operating member 16 after the pipe body 5 and the meter 4 are both connected and locked, Thereby, the surface of the meter 4 is rotated to an easily observable orientation. According to this, the present invention can achieve the effect of convenient construction and saving man-hour.

In addition, at least one expansion slot 17 is provided around the outer periphery of the body 12 or the inner periphery of the sleeve 21 within the range in which the hollow chamber 23 is closed by the leakage stopper 25, so as to expand the hollow chamber 23. The volume can be used to buffer the pressure change by the enlarged hollow chamber 23 when the tube body 5 faces a sudden pressure change, thereby making the sensing of the meter 4 more accurate. In this embodiment, the expansion slot 17 is disposed around the outer periphery of the body 12.

However, the disclosure of the above embodiments is only used to illustrate the present invention and is not intended to limit the present invention. Therefore, the replacement of equivalent components should still belong to the scope of the present invention.

In summary, those skilled in the art can understand that the present invention can indeed achieve the aforementioned purpose, and it has indeed complied with the provisions of the Patent Law, and filed an application in accordance with the law.
