Description

一种扭扭车拉绳伸缩装置
技术领域
本实用新型涉及一种扭扭车拉绳伸缩装置。
背景技术
扭扭车以其神奇的动力,令人遐想的外观设计,集环保、娱乐、健身于一体,深受孩子们的喜爱。目前市面上的妞妞车作为一种简单的儿童玩具,大都只能靠左右转动方向盘来实现妞妞车的前后行驶,并没有其他的功能。结构、功能较为单一。
实用新型内容
本实用新型的目的是提供一种扭扭车拉绳伸缩装置,以克服现有技术存在的上述不足。
本实用新型的目的是通过以下技术方案来实现:
一种扭扭车拉绳伸缩装置,包括壳体和固定块,所述壳体内设有空心柱形结构的旋转导轨,所述壳体包括前壳和后壳,所述前壳上设有若干螺纹孔一,所述后壳和固定块上与所述螺纹孔一对应的位置分别设有螺纹孔二和螺纹孔三,所述前壳、后壳以及固定块通过所述螺纹孔一、螺纹孔二、螺纹孔三以及配套的螺丝固定连接;所述旋转导轨内侧套装有复位弹片,所述复位弹片与所述后壳固定连接;所述旋转导轨外侧套装有螺旋缠绕的拉绳,所述拉绳上设有自由端,所述前壳以及后壳上与所述拉绳的自由端对应的位置均设有开口,所述拉绳的自由端从所述开口处伸出。
进一步的,所述旋转导轨两端均设有环形固定板。
进一步的,所述拉绳紧密套装在所述旋转导轨外侧。
进一步的,所述复位弹片的外侧壁与所述旋转导轨的内侧壁紧密贴合。
本实用新型的有益效果为:动作灵活,结构简单,安全快捷;不需要动力装置,操作简单,非常适合儿童。
附图说明
下面根据附图对本实用新型作进一步详细说明。
图1是本实用新型实施例所述扭扭车拉绳伸缩装置的结构示意图;
图2是本实用新型实施例所述扭扭车拉绳伸缩装置的爆炸图;
图3是本实用新型实施例所述扭扭车拉绳伸缩装置的安装示意图。
图中:
1、前壳;11、开口;2、拉绳;21、自由端;3、旋转导轨;31、环形固定板;4、复位弹片;5、后壳;6、螺丝。
具体实施方式
如图1-3所示,本实用新型实施例所述的一种扭扭车拉绳伸缩装置,包括壳体和固定块,所述壳体内设有空心柱形结构的旋转导轨3,所述壳体包括前壳1和后壳5,所述前壳1上设有若干螺纹孔一,所述后壳5和固定块上与所述螺纹孔一对应的位置分别设有螺纹孔二和螺纹孔三,所述前壳1、后壳5以及固定块通过所述螺纹孔一、螺纹孔二、螺纹孔三以及配套的螺丝6固定连接;所述旋转导轨3内侧套装有复位弹片4,所述复位弹片4与所述后壳5固定连接;所述旋转导轨3外侧套装有螺旋缠绕的拉绳2,所述拉绳2上设有自由端21,所述前壳1以及后壳5上与所述拉绳2的自由端21对应的位置均设有开口11,所述拉绳2的自由端21从所述开口11处伸出。
所述旋转导轨3两端均设有环形固定板31。所述拉绳2紧密套装在所述旋转导轨3外侧。所述复位弹片4的外侧壁与所述旋转导轨3的内侧壁紧密贴合。
具体使用时:拉动拉绳2,旋转导轨3开始转动,从而使复位弹片4缠绕圈数增多,储备弹性势能;松掉拉绳2,复位弹片4储备的弹性势能转化成动能使旋转导轨3向相反的方向转动,从而实现拉绳2的自动收缩功能。
本实用新型不局限于上述最佳实施方式,任何人在本实用新型的启示下都可得出其他各种形式的产品,但不论在其形状或结构上作任何变化,凡是具有与本申请相同或相近似的技术方案,均落在本实用新型的保护范围之内。
