Detailed description of the invention

Below in conjunction with accompanying drawing, technical scheme of the present invention is described further.

As shown in Figure 3, in prior art, conventional bottle cap comprises: upper cover, anti-theft ring, connecting bridge, the bottom of described upper cover connects anti-theft ring by connecting bridge, and upper interior surface has thread, and the thread of this thread and bottleneck outside face engages each other.

Under the state that this structure is tightened at upper cover and bottleneck, can ensure good leak tightness, in bottle, liquid is not easy to overflow, when anti-theft ring receives destruction, upper cover easily loosens under the effect of external force, causes intermeshing thread to unclamp, there is space in upper cover and bottleneck, liquid outflow in bottle.

As shown in Figure 1-2, a kind of anti-back structure, comprising: lid, cylindrical shell, and described lid inside face is provided with thread, and the thread in lid encloses along inside face around 3.Described cylindrical shell outer surface of upper has thread equally, and thread encloses along outside face around 4.

Under described lid and cylindrical shell tightening state, the thread in lid tightly engages with the thread outside cylindrical shell.

Described lid inside face arrange between thread and thread along lid inside face around retaining thread, described retaining thread is triangle convex body, in identical direction arrange, in order to better reach retaining object, triangle convex body is vertical triangle convex body.Therefore the high portion of vertical triangle convex body forms a space with between the lower curtate of adjacent vertical triangle convex body, the object being in this space easily passes through from the inclined-plane of vertical triangle convex body, and be difficult to pass through from vertical triangle convex body vertical surface, such displacement and stopping function are just formed.

Arrange between the thread of the outside face above described cylindrical shell and thread along barrel outer surface around retaining thread, this retaining thread is similarly vertical triangle convex body, arranges in identical direction.

As shown in Figure 4, in the process of tighten lid and cylindrical shell, constantly sliding from the lower curtate of retaining thread cylindrical shell along inclined-plane in the high portion of the retaining thread in lid, through high portion, arrives adjacent lower curtate, so continuous circulation, until lid and cylindrical shell are tightened.

In the process that lid and cylindrical shell are unscrewed, the high portion of the retaining thread in lid cannot by the high portion of barrel outer surface retaining thread, and therefore lid and cylindrical shell cannot rotate.

The application of anti-back structure provided by the present invention, comprising:

Be applied to the linking of body, as shown in Figure 5, the first body and the second body need to be connected,

First the first cylindrical shell diameter on demand and length are fixed on the first body needing to be connected outside;

Then the second cylindrical shell diameter on demand and length are fixed on the second body needing to be connected outside;
