Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and relates to connectors based on dental equipment. Background Technology

[0002] Dental equipment, also known as dental devices, refers to the collective term for various equipment, machines, instruments, and accessories specifically manufactured and / or provided to qualified personnel for use in dental clinical practice and / or related procedures. To better facilitate the work of dentists, dental chairs typically need to be connected to mouthwash basins. This requires a connector to connect the mouthwash basin and the drainage pipe. Existing connectors have a double-threaded structure, which, while ensuring good connection stability, offers poor lubrication. Therefore, we designed a connector based on dental equipment. Summary of the Invention

[0003] The purpose of this invention is to provide a connector for dental equipment to solve the problems mentioned in the background art.

[0004] The objective of this utility model can be achieved through the following technical solution: a connector for dental equipment, comprising a connector body, the connector body being composed of a metal connecting section, an internally threaded connecting section, and a threaded connecting post. The two ends of the metal connecting section are welded to the internally threaded connecting section and the threaded connecting post, respectively. One end of the internally threaded connecting section is provided with an internally threaded channel. The end of the internally threaded connecting section is provided with four annularly distributed insertion holes. Each of the four insertion holes contains an oil reservoir. The internally threaded connecting section contains a first lubricating oil channel communicating with the insertion holes. The inner wall of the metal connecting section contains a second lubricating oil channel communicating with the first lubricating oil channel. The second lubricating oil channel communicates with the opening of the threaded connecting post.

[0005] In the aforementioned connector based on dental equipment, a rear filter and a pre-filter are installed in the inner channel of the metal connector section, and a long rod is fixedly connected between the rear filter and the pre-filter.

[0006] In the aforementioned connector for dental devices, one end of the rear filter is provided with a magnetic snap-fit ​​connector.

[0007] Compared with existing technologies, the advantages of this utility model for dental equipment connectors are as follows: Four annularly distributed insertion holes are provided at the end of the internally threaded connection section for installing an oil reservoir cylinder. A first lubricating oil passage communicating with the insertion holes is provided inside the internally threaded connection section, and a second lubricating oil passage communicating with the first lubricating oil passage is provided on the inner wall of the metal connection section. The second lubricating oil passage communicates with the gap of the threaded connection cylinder, achieving a good lubrication effect and reducing wear on the connector. Furthermore, the inclusion of a rear filter, a front filter, a long rod, and a magnetic snap-fit ​​connector provides excellent filtration of impurities, and allows for quick removal of filtered impurities during cleaning, ensuring cleanliness.

[0010] In the diagram, 1 is the metal connecting section; 2 is the internal thread connecting section; 3 is the threaded connecting column; 4 is the oil reservoir cylinder; 5 is the first lubricating oil passage; 6 is the second lubricating oil passage; 7 is the rear filter screen; 8 is the front filter screen; 9 is the long rod; 10 is the internal threaded channel; and 11 is the magnetic clamp connector. Detailed Implementation

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1 and Figure 2 As shown, this utility model is based on a connector for dental equipment;

[0013] The connector body comprises a metal connecting section 1, an internally threaded connecting section 2, and a threaded connecting post 3. The two ends of the metal connecting section 1 are welded to the internally threaded connecting section 2 and the threaded connecting post 3, respectively. One end of the internally threaded connecting section 2 is provided with an internally threaded channel 10. The end of the internally threaded connecting section 2 is provided with four annularly distributed insertion holes. Each of the four insertion holes is provided with an oil reservoir cylinder 4. The internally threaded connecting section 2 is provided with a first lubricating oil passage 5 that communicates with the insertion holes. The inner wall of the metal connecting section 1 is provided with a second lubricating oil passage 6 that communicates with the first lubricating oil passage 5. The second lubricating oil passage 6 communicates with the hole of the threaded connecting post 3.

[0014] In this embodiment, to ensure effective filtration of impurities and to facilitate rapid removal of filtered impurities during cleaning, a post-filter 7 and a pre-filter 8 are installed in the inner channel of the metal connecting section 1, and a long rod 9 is fixedly connected between the post-filter 8 and the pre-filter 8. A magnetic snap-fit ​​connector 11 is provided at one end of the post-filter 7.

[0015] Working principle: The internally threaded connecting sections 2 and threaded connecting posts 3 at both ends of the metal connecting section 1 can be connected to the connecting parts of dental equipment. Four annularly distributed insertion holes are provided at the ends of the internally threaded connecting section 2, allowing the installation of an oil reservoir cylinder 4. A first lubricating oil passage 5 communicating with the insertion holes is provided inside the internally threaded connecting section 2. A second lubricating oil passage 6 communicating with the first lubricating oil passage 5 is provided on the inner wall of the metal connecting section 1. The second lubricating oil passage 6 communicates with the gaps in the threaded connecting post 3, providing good lubrication and reducing wear on the connector. The installation of a rear filter 7, a pre-filter 8, a long rod 9, and a magnetic clamp connector 11 effectively filters impurities, and during cleaning, the filtered impurities can be quickly removed, ensuring cleanliness.
