Description

一种牙科抛光弯角 技术领域
本实用新型涉及一种牙科抛光弯角，属于医疗器械用品技术领域。
背景技术
牙科用抛光弯角是应用在口腔科的基本医疗器械之一，通过带动弯角上抛光杯低速转动从而对口腔进行清洁抛光，抛光弯角是配合洗牙机一齐使用的，需直接深入口腔内部，所以对口腔的角落都要求延伸得到，现有技术中的抛光弯角安装方式多采用胶粘或者螺接固定的方式，装配繁琐。
实用新型内容
针对现有技术存在的上述问题，本实用新型的目的在于提供一种牙科抛光弯角，通过合理优化结构，采用多组限位结构，简化安装步骤，减少配件，降低生产成本。
为实现上述实用新型目的，本实用新型采用的技术方案如下：
一种牙科抛光弯角，包括壳体、传动组件、限位件I、限位件II以及抛光杯，传动组件包括传动杆I和传动杆II，传动杆II一端与传动杆I铰接，另一端安装抛光杯，传动杆I和传动杆II铰接位置分别设有齿轮I和齿轮II，限位件I套接在传动杆I与壳体内壁之间，限位件II套接在传动杆II与壳体内壁之间。
优选地，壳体内壁包括安设传动杆I的安装槽I和安设传动杆II的安装槽II，其中安装槽I含有限位段I和限位段II，限位件I位于限位段II内，限位段I和限位段II的作用在于一方面防止传动杆I脱落，另一方起到纤维的作用，防止传动杆I会发生晃动造成移位。
优选地，限位段I靠近安装槽II一端设有凸台，凸台起到限位作用。
优选地，限位段II上设有限位槽，对应地，限位件I上设有限位凸台，装配完成后，限位凸台卡接在限位槽内，起到定位的作用。
优选地，传动杆I上设有限位环I和限位环II，装配后，限位环I和限位环II分别位于限位段I两端。限位环I与凸台抵触起到限位作用，限位环II与限位件I抵触起到限位作用，形成两端限位，提高了稳定性。
优选地，齿轮I和齿轮II为相互啮合的锥形齿轮，都位于安装槽II内，锥形齿轮相互啮合，有效地防止传动杆II脱落。
与现有技术相比，本实用新型的有益效果是：取消了传统的螺接固定方式，采用限位件I与壳体卡接形成固定的方式，简化了安装步骤，传动杆I和传动杆II之间采用伞状齿轮相互啮合，起到传动作用的同时，也通过齿轮结构，起到限位的作用，防止传动杆II脱落，进一步减少了用于固定的安装配件，降低了生产成本，因此具有很好的推广价值和应用前景。

具体实施方式
下面结合附图和优选实施例对本实用新型作进一步详细完整地说明。
图1-3为本实用新型提供的一种牙科抛光弯角的优选实施例示意图。如图1-3所示，该牙科抛光弯角包括壳体1、传动组件2、限位件I3、限位件II4以及抛光杯5，传动组件2包括传动杆I201和传动杆II202，传动杆II202一端与传动杆I201铰接，另一端安装抛光杯5，传动杆I201和传动杆II202铰接位置分别设有齿轮I203和齿轮II204，限位件I3套接在传动杆I201与壳体1内壁之间，限位件II4套接在传动杆II202与壳体1内壁之间，壳体1内壁包括安设传动杆I201的安装槽I101和安设传动杆II202的安装槽II102，其中安装槽I101含有限位段I103和限位段II104，限位件I103位于限位段II104内，限位段I103靠近安装槽II102一端设有凸台105，限位段II104上设有限位槽106，对应地，限位件I3上设有限位凸台301，传动杆I201上设有限位环I205和限位环II206，装配后，限位环I205和限位环II206分别位于限位段I103两端，齿轮I203和齿轮II204为相互啮合的锥形齿轮，都位于安装槽II102内。
安装过程中，首先将传动杆I插入安装槽I，传动杆II插入到安装槽II，将限位件II插入到传动杆II与壳体之间，然后在传动杆II端子上固定好抛光杯，在此过程中，保证齿轮I和齿轮II相互啮合，并且使传动杆I上所设有限位环I和限位环II分别位于限位段I两端，限位环I与壳体内壁凸台相抵触，最后将限位件I插入到传动杆I与壳体内壁之间，使限位件I与限位环II相互抵触，且限位件I上的限位凸台卡接在限位槽内，即完成安装。
与现有技术相比，本实用新型的有益效果是：取消了传统的螺接固定方式，采用限位件I与壳体卡接形成固定的方式，简化了安装步骤，传动杆I和传动杆II之间采用伞状齿轮相互啮合，起到传动作用的同时，也通过齿轮结构，起到限位的作用，防止传动杆II脱落，进一步减少了用于固定的安装配件，降低了生产成本，因此具有很好的推广价值和应用前景。
以上显示和描述了本实用新型的基本原理和主要特征和本实用新型的优点。本行业的技术人员应该了解，本实用新型不受上述实施例的限制，上述实施例和说明书中描述的只是说明本实用新型的原理，在不脱离本实用新型精神和范围的前提下，本实用新型还会有各种变化和改进，这些变化和改进都落入要求保护的本实用新型范围内。本实用新型要求保护范围由所附的权利要求书及其等效物界定。
