Description

A screw with coaxial docking function

一、技术领域1. Technical field

本实用新型涉及紧固件领域，尤其与螺丝相关。The utility model relates to the field of fasteners, in particular to screws.

二、背景技术2. Background technology

目前市场上通用的螺丝的端部形状有一字槽、十字槽、外六角、内六角等，其共同的缺点是当螺丝批或扳手等驱动工具对其拧紧或拧松时，由于相互存在较大的间隙，不能保证良好的同轴度，以致受力面发生倾斜等原因，使其与驱动工具之间很难定位和固定，使螺丝产生歪斜，磨损，打滑，脱落等，直接影响工程质量和施工效率以及工具的使用寿命。At present, the end shape of the screws commonly used in the market has a word groove, a cross groove, an external hexagon, an internal hexagon, etc., and its common disadvantage is that when the driving tools such as screwdrivers or wrenches are tightened or loosened, due to the large mutual The gap between the screw and the driving tool cannot guarantee a good coaxiality, so that the force-bearing surface is inclined and other reasons, making it difficult to locate and fix the drive tool, causing the screw to be skewed, worn, slipped, and falling off, which directly affects the quality of the project. Construction efficiency and tool life.

三、技术解决方案3. Technical solutions

本实用新型提供了一种具有同轴对接功能的螺丝，它采用了含锥度的帽头或驱动槽或中心定位凹穴与同一锥度的套筒或驱动齿或中心定位轴头之间的对应套合，使其侧壁之间无多余间隙，使螺丝与驱动工具之间实现了可逆的同轴对接，因此螺丝不再出现歪斜、磨损、打滑、脱落等现象。The utility model provides a screw with a coaxial butt joint function, which adopts a corresponding sleeve between a tapered cap head or a driving groove or a center positioning recess and a same taper sleeve or a driving tooth or a center positioning shaft head. There is no extra gap between the side walls, and the reversible coaxial butt joint between the screw and the driving tool is realized, so the screw no longer appears skewed, worn, slipped, and falls off.

为达到上述目的，本实用新型的技术解决方案是：一种具有同轴对接功能的螺丝，它包括螺丝主干，帽头，驱动槽，中心定位凹穴，其特征在于：它还包括锥度侧壁；帽头位于螺丝主干顶端，与螺丝主干同轴且连成一体，驱动槽位于帽头端部，与帽头中心形成旋转对称，中心定位凹穴位于帽头端面中心，并向螺丝主干延伸，锥度侧壁位于帽头或驱动槽或中心定位凹穴之侧面，与帽头或驱动槽或中心定位凹穴形成一体，其锥度和深度的大小必须同时满足连接的强度和手动插拔的灵活度的技术要求范围进行设置。In order to achieve the above object, the technical solution of the utility model is: a screw with a coaxial butt joint function, which includes a screw trunk, a cap head, a driving groove, and a center positioning cavity, and is characterized in that it also includes a tapered side wall The cap head is located at the top of the screw trunk, coaxial and integrated with the screw trunk, the driving groove is located at the end of the cap head, and forms rotational symmetry with the center of the cap head, and the central positioning recess is located at the center of the end face of the cap head and extends toward the screw trunk. The tapered side wall is located on the side of the cap head or the driving groove or the central positioning cavity, and is integrated with the cap head or the driving groove or the central positioning cavity. The taper and depth must meet the strength of the connection and the flexibility of manual insertion and removal. The range of technical requirements is set.

五、具体实施方式5. Specific implementation

下面结合附图对本实用新型的实施例作进一步详细描述：一种具有同轴对接功能的螺丝，它包括螺丝主干(1)，帽头(2)，驱动槽(3)，中心定位凹穴(4)，其特征在于：它还包括锥度侧壁(5)；帽头(2)位于螺丝主干(1)顶端，与螺丝主干(1)同轴且连成一体，驱动槽(3)位于帽头(2)端部，与帽头(2)中心形成旋转对称，中心定位凹穴(4)位于帽头(2)端面中心，并向螺丝主干(1)延伸，锥度侧壁(5)位于帽头(2)或驱动槽(3)或中心定位凹穴(4)之侧面，与帽头(2)或驱动槽(3)或中心定位凹穴(4)形成一体，其锥度和深度的大小必须同时满足连接的抗折强度和手动插拔的灵活度的技术要求范围进行设置。Below in conjunction with accompanying drawing the embodiment of the present utility model is described in further detail: a kind of screw with coaxial butt joint function, it comprises screw trunk (1), cap head (2), driving groove (3), center positioning recess ( 4), it is characterized in that: it also includes a tapered side wall (5); the cap head (2) is located at the top of the screw trunk (1), coaxial with the screw trunk (1) and integrated, and the driving groove (3) is located at the top of the cap The end of the head (2) forms rotational symmetry with the center of the cap head (2), the center positioning recess (4) is located at the center of the end face of the cap head (2) and extends toward the screw trunk (1), and the tapered side wall (5) is located The side of cap head (2) or driving groove (3) or center positioning recess (4) forms an integral body with cap head (2) or driving groove (3) or center positioning recess (4), and its taper and depth The size must meet the range of technical requirements for the flexural strength of the connection and the flexibility of manual plugging and unplugging.

工作时，将驱动工具上对应的含相同锥度的套筒或驱动齿或中心定位轴头对准螺丝的帽头(2)或驱动槽(3)或中心定位凹穴(4)，然后相互插入并压紧到位，直至侧面完全接触和贴合至无多余间隙后，顺时针旋转驱动工具，即可使螺丝拧紧，如逆时针转动，则可使螺丝拧松或取出。当驱动工具用力向压紧的反方向拔出时，可实现相互分离。When working, align the corresponding sleeve with the same taper or the driving tooth or the central positioning shaft head on the driving tool with the cap head (2) or the driving groove (3) or the central positioning cavity (4) of the screw, and then insert each other And press it in place until the sides are fully contacted and fit without any excess gap, then turn the drive tool clockwise to tighten the screw, and turn it counterclockwise to loosen or remove the screw. When the driving tools are forced to be pulled out in the opposite direction of pressing, they can be separated from each other.
