防盗表具连接管制造技术

本实用新型专利技术涉及一种防盗表具连接管，属于连接软管技术领域。该连接管包括波纹管体，所述波纹管体的一端是接头，另一端是端部带止口的接管；所述接管外套装防盗螺母，所述止口构成防盗螺母的轴向限位；所述防盗螺母由外套与嵌在外套内的螺纹内套构成，外套与内套的结合面制有单向啮合结构。这样，当旋紧防盗螺母使之与燃气计量表螺纹连接时，该螺母外套可以带动内套旋转。而旋紧之后，当试图反拧防盗螺母时，外套无法带动内套，螺纹连接无法松开，从而达到防卸、防盗的目的。（*该技术在2018年保护过期，可自由使用*）

Connecting tube for anti-theft Watch

The utility model relates to an anti-theft watch connecting tube, which belongs to the technical field of connecting hoses. The connecting pipe comprises a corrugated pipe body, wherein one end of the corrugated pipe body is the connector, the other end is over the end with a rabbet; the nozzle is sheathed outside the anti-theft nut, the spigot to form the axial limiting nut; the anti-theft nut comprises a casing and embedded in the outer sleeve thread internal sleeve a one-way engagement with the sleeve and the inner sleeve structure surface system. Thus, when the anti-theft nut is tightened to connect with the gas meter, the nut outer sleeve can drive the inner sleeve to rotate. When the screw is tightened, the coat can not drive the inner sleeve when the anti-theft nut is reversed, and the thread connection can not be loosened, so as to achieve the purpose of preventing unloading and anti-theft.
