Description

一种螺母 技术领域
本实用新型涉及一种带手柄且手柄易折断的螺母。
背景技术
螺母是机械领域应用很广泛的紧固零件。螺母有很多种应用场景，可以在机械设备外部进行紧固，也可以在设备内部进行紧固。内部紧固时，需要先将螺母放置进设备的凹槽或内凹空间中内，然后用螺栓从凹槽或内凹空间外部旋进螺母完成紧固。
但多数机械设备上的凹槽或内凹空间开口比较小，或凹槽或内凹空间较深。现有技术螺母绝大部分都是光秃秃的独立整体，螺母上没安装其余部件，现有技术螺母放进去凹槽或内凹空间之后，不易用手或用其他辅助器件将螺母的位置固定住。螺母位置不固定的情况下将螺栓从外部旋进螺母，会导致紧固效果不理想，紧固完成后螺母螺栓都容易松动。
发明内容
为了克服了上述技术弊端，本实用新型提供了一种螺母，在螺母主体上设置了手柄，手柄与螺母主体连接并形成连接部，且该连接部容易被折断。
本实用新型的有益技术效果在于：在螺母主体上设置了手柄，在设备上进行内部紧固时，将螺母放进设备的凹槽或内凹空间后，可以用手扶住手柄或用其他辅助器件夹住手柄，从而将螺母的位置固定住，再配合螺栓进行紧固。本实用新型螺母紧固时不易松动，克服了螺母位置不固定导致的紧固不理想的 技术弊端。本实用新型螺母紧固完成后可以折断手柄，不占用设备上其他部件的安装位置，也不影响设备的美观。
为了更好地实现技术效果，本实用新型优选为塑料螺母，相比于金属螺母质量较轻。塑料螺母相比于金属螺母也具有更好的弹性，紧固时也会产生更好的紧固力。

具体实施方式
下面将结合本实用新型的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述。
本实用新型的一种螺母，在螺母主体1上安装了手柄2，手柄2与螺母 主体1连接并形成连接部21，该连接部21容易被折断。在机械设备3上应用该种螺母时，可以用手扶住手柄2或用其他辅助器件夹住手柄2，从而将螺母的位置固定住，再配合螺栓11进行紧固。本实用新型螺母紧固时不易松动，紧固效果较为理想。本实用新型螺母紧固完成后可以折断手柄2，不占用设备上其他部件的安装位置，也不影响设备的美观。同时本实用新型优选为塑料螺母，相比于金属螺母质量较轻。塑料螺母相比于金属螺母也具有更好的弹性，紧固时也会产生更好的紧固力。
进一步地，手柄1还包括与连接部21一体成型的杆部22，在由杆部22到连接部21的方向上，连接部21的横截面积逐渐减小。连接部21与螺母主体1的接触面横截面积达到最小，以方便在螺母紧固完成后，按压杆部22，可以轻易将连接部21折断。
优选地，本实用新型连接部21可以设置为多种形状，连接部21与螺母主体1的接触面也相应地为多种形状。连接部21与螺母主体1的接触面可以是多边形面、封闭的弧形平面，也可以是多边形与封闭的弧形组合而成的封闭图形平面。只要满足“在由杆部22到连接部21的方向上，连接部21的横截面积逐渐减小”这一条件，任何形状的接触面均属于落入本实用新型的保护范围。
在进一步地实施例中，本实用新型优选地将连接部21与螺母主体1的接触面设置为矩形面或圆形平面。
当接触面为矩形面时，将矩形面的边长控制在在0.3毫米至1.5毫米之间。当接触面为为圆形平面时，将圆形平面的直径控制在0.3毫米至1.5毫米之间。
优选地，本实用新型将手柄2与螺母主体1一体成型设计，这样在制造时可以直接将手柄2与螺母主体1注塑为一体成型的结构，工艺简单方便。
优选地，本实用新型螺母上的手柄2设置为一个或两个，手柄2为一个时，可以安装在螺母主体1的任何一个面上。当手柄2为两个时，优选地将手柄对称安装在螺母主体1上，以方便螺母可以顺利装进设备的凹槽中，螺母装进凹槽后，可以两边同时扶住或夹住手柄2以更好地固定住螺母的位置，加强紧固效果。
以上所述实施例仅表达了本专利的部分实施方式，其描述较为具体和详细，但并不能因此而理解为对本专利保护范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本专利构思的前提下，还可以做出若干变形和改进，这些都属于本专利的保护范围。因此，本专利的保护范围应以所附权利要求为准。
