Description

Technical Field

[0001] The utility model relates to the technical field of sound monitoring, in particular to a rotatable waterproof joint installation structure for an instrument. Background Art

[0002] External modules (such as antennas, etc.) on the instrument are usually threaded or jointed. One common method is to assemble the antenna end and the instrument into a threaded structure, with an O-ring for waterproofing; another common method is a threaded joint, which includes a connecting pipe, a nut, a retaining ring (some do not require a retaining ring) and a sealing gasket. When installing, first install the connecting pipe thread to the instrument, then put the nut on the open end of the connecting pipe, then clamp the retaining ring on the connecting pipe, and finally tighten the nut thread and the external module thread.

[0003] The main drawbacks are:

[0004] (1) The external module is installed behind the instrument through a threaded connection. Since the length of the threads of different instruments varies, the position of the external module after tightening is uncertain. During installation, the instrument may interfere with industrial pipelines or other instruments, resulting in failure to install. (2) This type of threaded union usually requires the threads to be tightened hard to ensure the sealing performance of the connection. After tightening the threads, the angle of the module is difficult to control, and the operation is time-consuming and laborious. (3) After the union is installed, the threads need to be loosened to adjust the angle of the external module, which is not user-friendly. Utility Model Content

[0030] Example

[0031] Combined with Figure 1-6 A rotatable waterproof joint installation structure for an instrument, the connecting body is a waterproof joint 20, which is mainly used for connecting an external module 10 with an instrument 30. The waterproof joint 20 includes a connecting pipe 21, a sealing ring 22, a sealing rubber ring 23 and a mounting nut 24. A first internal thread 31 for threaded connection is provided on the connecting side of the instrument 30. The external module 10 includes a mounting portion 11 and a main body 12. The mounting nut 24 includes a second internal thread 241 and a compression portion 242.

[0032] The connecting tube 21 is provided with a first external thread 211, a second external thread 212 and a plurality of claws 213 from left to right, respectively. The claws 213 are a plurality of independent individuals arranged around one side of the connecting tube 21. The sealing ring 22 is located between the first external thread 211 and the separating protrusion. The sealing ring 22 is used for connecting the instrument 30 with the waterproof flexible joint 20 so that water vapor will not overflow from the instrument 30. The sealing rubber ring 23 is used for connecting the waterproof flexible joint 20 with the external module 10 so that water vapor will not overflow from the external module 10.

[0033] During installation, the first external thread 211 is screwed into the first internal thread 31 of the instrument, and the sealing ring 22 is compressed to form a seal. Then the sealing rubber ring 23 is inserted into the claws 213, and the mounting nut 24 is sleeved on the claws 213. After the mounting portion 11 of the external module 10 is inserted into the sealing rubber ring 23, the second internal thread 241 and the second external thread 212 of the mounting nut are tightened. In this process, the compression portion 242 of the mounting nut 24 will tighten the claws 213 inward, thereby compressing the sealing rubber ring 23, locking the mounting portion 11, and forming a seal. Since the sealing rubber ring 23 is an elastic member, it does not affect the rotation of the external module while forming a seal, so that its position can be adjusted.

[0034] In other embodiments, the connecting pipe 21, the sealing ring 22, the sealing rubber ring 23 and the mounting nut 24 are assembled in advance and installed on the meter 30 as a sub-component. After the meter 30 is installed and fixed on site, the external module 10 is installed. At this time, it is only necessary to confirm that the mounting nut 24 is not in a tightened state, insert the mounting part 11 into the sealing rubber ring 23 through the mounting nut 24, and according to the current meter installation situation, the external module 10 can be rotated to adjust to a suitable installation position, and the mounting nut 24 can be rotated to lock it, thereby achieving a waterproof effect, and facilitating use and installation. At the same time, it is also convenient to transport as a sub-component pre-installed on the meter 30.

[0035] By changing the shape of the protrusion of the mounting portion, various mounting effects can be achieved. When the annular protrusion feature is a rectangle 111, the mounting effect of the external module is axial locking and radial rotation; when the rectangular edge of the annular protrusion feature near the instrument side is chamfered 112, the mounting effect of the external module is easy to enter and difficult to exit, and radial rotation; when the rectangular edges on both sides of the annular protrusion feature are chamfered 113, the mounting effect of the external module is easy to enter and exit, and radial rotation.

[0036] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
