Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a child lock cylinder 100, which includes a bottom cylinder 1 and a pressing member 2.

The end 1 end of a section of thick bamboo is one end opening one end and seals and be hollow structure, for example for the cylinder for hold some graininess, the article of dust. In the present embodiment, the base cylinder 1 is made of a paper material.

The pressing part 2 comprises a pressing sleeve 21, a cylinder cover 22 covering one end of the pressing sleeve 21 and a connecting rib 23 connecting the cylinder cover 22 to the pressing sleeve 21. In this embodiment, the pressing member 2 is made of plastic.

Specifically, the extrusion sleeve 21 is a hollow structure with two open ends, in this embodiment, the shape of the extrusion sleeve 21 matches with the bottom cylinder 1, for example, it is a cylindrical structure.

The extrusion sleeve 21 is close to the terminal surface of cover 22 extends outwards and forms annular extension arm 211, and the diameter ratio of extension wall 211 is 2 ~ 3 millimeters bigger than the external diameter of end section of thick bamboo 1, the thickness of extension wall 211 is 1 millimeter. The inner wall of the extrusion sleeve 21 is recessed to form a ring of grooves 212, and the groove depth of the grooves 212 is smaller than the wall thickness of the extrusion sleeve 21. One end of the extrusion sleeve 21, which is far away from the cover 22, is inserted into the bottom cylinder 1 from the open end of the bottom cylinder 1 and forms a fixed connection.

The cylinder cover 22 is arranged at one end of the extrusion sleeve 21, the cylinder cover 22 is provided with an annular rib 221 which is matched with the groove 212, the cylinder cover 22 is arranged on the extrusion sleeve 21, and the rib 221 is clamped into the groove 212.
