AI Technical Summary

Technical Problem

Dental cell phone pipelines are easily discounted at the connection to the dental cell phone, resulting in damage.

Method used

A dental mobile phone pipeline anti-folding device is designed, including a first combined tube sleeve and a second combined tube sleeve. The sleeve is arranged outside the connection between the dental mobile phone and the plastic pipeline. It is fixed by combining the mounting bumps and the slot position. The overall arc-shaped design provides support and reduces friction and wear.

Benefits of technology

It effectively reduces the friction and wear between the plastic pipelines and the dental mobile phones when moving, provides support for the plastic pipelines, and extends the service life of the pipeline.

Abstract

The utility model discloses a dental handpiece pipeline anti-folding device, which relates to the field of dental auxiliary appliances, and comprises a first combined pipe sleeve and a second combined pipe sleeve, the first combined pipe sleeve and the second combined pipe sleeve are sleeved outside the joint of a dental handpiece and a plastic pipeline, the plastic pipeline is inserted at the tail end of the dental handpiece, and the plastic pipeline is connected with the dental handpiece. One side of the first combined pipe sleeve and the second combined pipe sleeve are mutually inserted to be combined and fixed, and the first combined pipe sleeve and the second combined pipe sleeve are the same in structure. The first combined pipe sleeve and the second combined pipe sleeve can block and protect the joint of the plastic pipeline and the dental handpiece, the situation that when the dental handpiece moves, the plastic pipeline is abraded due to back-and-forth friction between the plastic pipeline and the dental handpiece is reduced, certain supporting performance is provided for the plastic pipeline through the overall arc-shaped design of the combined pipe sleeves, and the service life of the plastic pipeline is prolonged. And the tail end is designed into an arc-shaped closing opening, so that the abrasion generated when the plastic pipeline is used can be reduced.
