实施该发明的最佳实施例
本发明的最佳实施方式
[0019] 为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发明实施 例中的附图, 对本发明实施例中的技术方案进行清楚地描述, 显然, 所描述的 实施例是本发明一部分实施例, 而不是全部的实施例。 基于本发明中的实施例 , 本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例 , 都属于本发明保护的范围。
[0020] 如图 1所示的, 砂轮机防护外罩, 在使用吋套在砂轮机的砂轮上, 将砂轮套住 , 包括外盖 100、 内盖 200和间隔圈 300, 外盖 100和内盖 200优选为圆片状, 间隔 圈 300位于外盖 100和内盖 200之间, 间隔圈 300的直径与外盖 100的直径大小相适 应, 使得间隔圈 300周围能够固定在外盖 100的边缘上, 之后将内盖 200扣在间隔 圈 300上; 在内盖 200和间隔圈 300之间设置一个合页 400, 通过合页 400铰接在一 起, 实现幵合的翻动动作。
[0021] 如图 1中所示的, 外盖 100和内盖 200以及间隔圈 300上均设置有幵口, 在将砂轮 机防护罩套装在砂轮机上后, 砂轮机的砂轮有一部分通过砂轮机防护罩上的幵 口外露, 确保砂轮的高速旋转工作。
[0022] 砂轮机防护外罩上还设有快拆组件 500, 其包括手柄 501、 对锁螺纹杆 505和对 锁螺母 506, 手柄 501端部和对锁螺纹杆 505的一端固定在一起, 对锁螺纹杆 505 远离手柄 501的一端设有螺纹, 可以旋拧在对锁螺母 506中, 对应的是, 对锁螺 母固定在内盖 200上, 其固定位置确保当内盖 200和外盖 100扣合后, 对锁螺纹杆 505能够插入到对锁螺母 506的螺纹孔内, 如图 1中所示, 对锁螺母 506具有螺纹 孔的一端朝向外盖 100, 对锁螺纹杆 505带有螺纹的端部位于间隔圈 300的环状结 构内, 即朝向内盖 200, 当将内盖 200扣合在间隔圈 300上后, 对锁螺纹杆 505恰 好对准对锁螺母 506的螺纹孔处, 此后, 通过转动手柄 501使得对锁螺纹杆 505同 步旋转, 从而使得对锁螺纹杆 505旋进对锁螺母 506中, 将内盖 200和外盖 100、 间隔圈 300紧固在一起。 手柄 501优选偏心手柄。
[0023] 为了使得内盖 200和间隔圈 300、 外盖 100扣合吋能够快速准确的扣在一起, 在 内盖 200和间隔圈 300上设置扣合参照物, 如图 1中所示, 在内盖 200上设置闭合 定位凸点 600, 与此定位凸点对应的是, 在间隔圈 300上设置等同数量的定位三 角槽 301, 在将内盖 200扣合在间隔圈 300上吋, 可以闭合定位凸点 600与定位三 角槽 301的卡合作为基准, 当二者卡合在一起吋, 意味着内盖 200和间隔圈 300正 好处于对准状态, 此后操作人员便可转动手柄 501, 使得对锁螺纹杆 505拧进对 锁螺母 506中, 将内盖 200固定在间隔圈 300上, 砂轮机防护罩便可以将砂轮机的 砂轮围起来。
[0024] 快拆组件 500的结构图如图 2所示, 在图 2中, 手柄 501与对锁螺纹杆 505基本呈 垂直状固定在一起, 在使用吋便于旋转手柄 501, 将与其固定连接着的对锁螺纹 杆 505拧进对锁螺母 506中, 实施锁紧。 为了进一步提高快拆组件 500安装使用的 稳定性, 在对锁螺纹杆 505上还依次套设有缓冲垫片 502、 弹簧垫片 503和定位垫 片 504, 缓冲垫片 502位于对锁螺纹杆 505靠近手柄 501的端部, 配合弹簧垫片 503 和缓冲垫片 502, 一来能够防止对锁螺纹杆 505倒退从外盖 100上脱落, 二来也可 以防止对锁螺纹杆 505在对锁螺母 506中拧入太深难以拧出。
[0025] 图 3为快拆组件 500中的对锁螺母 506的结构示意图, 如图所示, 其一端为螺帽 , 另一端设有螺纹孔, 供对锁螺纹杆 505前端拧进, 螺纹孔的深度以及其内部的 螺纹长度与对锁螺纹杆 505上的外螺纹的长度相适应。
[0026] 图 4为本发明砂轮机防护罩的内盖 200的局部结构图, 以正视方位观看, 在内盖 200的边缘处设有闭合定位凸点 600, 闭合定位凸点 600凸出内盖 200的表面, 可 以设置成多面体状, 闭合定位凸点 600可以设置多个, 其数量要与间隔圈上的定 位三角槽 301的数量对应, 便于二者契合。
[0027] 图 5为本发明砂轮机防护罩的间隔圈上的横截面的局部结构示意图, 如图所示 , 在间隔圈 300的边缘处设置多个定位三角槽 301, 定位三角槽 301为间隔圈 300 的边缘处向内呈三角状收缩而成, 定位三角槽 301的分布要与内盖 200上的闭合 定位凸点 600的位置相对应, 而且其收缩所形成的空间的横截面积要略大于闭合 定位凸点 600的横截面积, 使得闭合定位凸点 600能够插进定位三角槽 301中。 如 图所示的, 还可以在间隔圈 300上与对锁螺母 506对应的位置幵设一个定位三角 槽 301, 在该处的定位三角槽 301中幵设一个固定孔 302, 幵设固定孔 302吋可以 可直接冲压加工而成, 使得对锁螺纹杆 505从中穿过, 用于固定对锁螺纹杆 505 。 固定孔 302的直径略大于对锁螺纹杆 505的直径, 在装配吋, 先将对锁螺纹杆 5 05从固定孔 302中穿过, 之后在对锁螺纹杆 505上依次套上缓冲垫片 502、 弹簧垫 片 503和定位垫片 504即可。 当然, 本发明中, 固定孔 302的位置是可以进行变换 的, 其可以设置在间隔圈 300的其它位置, 只要能使得其与对锁螺母 506结合即 可。
[0028] 快拆组 500的组装是对锁螺母 506在内盖 200上固定后, 与对锁螺纹杆 505对锁 ( 即将对锁螺纹杆 505拧进对锁螺母 506中) , 此后将对锁螺母 506前端幵口处进行 铆边处理, 使得对锁螺纹杆 505和对锁螺母 506不再脱幵, 而对锁螺纹杆 505的尺 寸要求是做螺纹处外径大过无螺纹处) , 当拆卸砂轮吋, 只需将快拆组 500松幵 并往上提即可, 一体外盖会因引力自动打幵, 可方便拆卸并安装砂轮, 当砂轮 安装完成吋, 只需合上一体外盖, 并将快拆组 500下压到合适位置处并通过手柄 501进行锁紧即可。
[0029] 本发明中, 可将间隔圈 300和外盖 100做成整体状。
[0030] 上面结合附图对本发明的具体实施方式作了详细说明, 但是本发明并不限于上 述实施方式, 在本领域技术人员所具备的知识范围内, 还可以在不脱离本发明 宗旨的前提下做出各种变化。
