Dental low speed handpiece disassembler

Abstract

A dental low-speed mobile phone disassembler, including a first sleeve, a first through hole and a second through hole communicated with each other are opened in the first sleeve, the diameter of the first through hole is smaller than the diameter of the second through hole, and the A second sleeve is installed in the first through hole, the bottom of the second sleeve is provided with a limiting lip matching the diameter of the second through hole, and the inner circumference of the top of the second sleeve is provided with a pressing lip , the bottom of the first sleeve is fitted with a third sleeve through threaded fit, and the inner periphery of the bottom of the third sleeve is provided with an upper convex edge. The NSK dental low-speed handpiece is specially used to disassemble the structure recorded in the background technology, which reduces the disassembly and maintenance time without destroying the parts, and ensures the maintenance quality.

Description

Technical field [0001] The present invention relates to the field of dental equipment maintenance, in particular to a low-speed dental destructurers phone. Background technique [0002] Handpiece dentistry is a common medical devices, to achieve treatment of the teeth or oral tissues by clamping different types of contacts, the conventional mobile phone taken NSK low speed dental mandrel with a clamping sleeve clamp the bur the holding structure, the clamping force applied to the sheath by snap spring disc spring is fixedly mounted on the shaft stopper groove, the outer periphery of the air motor is mounted using a threaded clamping ring secured to the overall structure of a minute and precise, if disassembly for each of the different parts will use proprietary tools, the actual operation is very troublesome, and even the use of demolition means a little violence, is likely to cause damage to parts, affecting the use of dental handpieces, the lack of such structures for special o...

AI Technical Summary

Problems solved by technology

[0002] Dental handpiece is a commonly used medical device in stomatology. It realizes the treatment of teeth or oral tissue by clamping various types of burs. The existing NSK dental low-speed handpiece uses a clamping sleeve and a mandrel to clamp the bur The holding structure, the disc spring that exerts thrust on the clamping sleeve is fixed and installed in the limit groove of the rotating shaft through the clamping spring. The installation of the air motor is fixed by a pressure ring with threads on the outer circumference. The overall structure is small and precise. If it is disassembled Different special tools are used for each different part. The actual operation is very troublesome, and even a slightly violent disassembly method is used, which is easy to cause damage to the parts and affect the use of the dental handpiece. Currently, there is no special tool for this type of structure in the market. Repair tools, resulting in too long disassembly time, repair quality is not guaranteed
