Detailed Description

The present invention will be further described with reference to the following specific embodiments.

The utility model discloses a press down safe storage tube of formula of unscrewing, be equipped with storage tube external screw thread 11 in the upper end of storage tube 1, the spiro union has inner cup 2 on storage tube external screw thread 11, processing has inner cup internal thread 21 including on lid 2, inner cup internal thread 21 cooperatees with storage tube external screw thread 11, be equipped with round platform shape arch 22 at the middle part at the up end of inner cup 2 including, the up end in the protruding 22 outside of round platform shape is equipped with the protruding 23 in first slope, the one end of the protruding 23 in first slope is the inclined plane, the other end is vertical face, the inclined plane on the protruding 23 in all first slopes is dextrorotation setting or is the levogyration setting, be equipped with enclosing cover 3 in the outside of inner cover 2, be equipped with flexure strip 31 at the lower terminal surface middle part of enclosing cover 3, flexure strip 31 cooperates with the protruding 22 in round platform shape, the lower terminal surface of enclosing cover 3 in the flexure strip 31 outside is equipped with the protruding 32 in second slope, the other end is vertical face, and the inclined plane on all the second slope archs 32 is dextrorotation setting or is the levogyration setting, and the inclined plane of second slope archs 32 and the inclined plane cooperation of first slope archs 23, the vertical face of second slope archs 32 and the vertical face cooperation of first slope archs 23 the inner wall of enclosing cover 3 is followed down and is equipped with round anti-falling arch 33.

The outer side wall of the outer cover 3 is provided with an anti-slip convex rib 34.

The circular truncated cone-shaped protrusion 22 and the inner cover 2 are coaxially arranged.

The elastic pieces 31 have at least three pieces, and the elastic pieces 31 are uniformly distributed around the axis of the outer cover 3.

The cross section of the elastic sheet 31 is arc-shaped, and the arc and the outer cover 3 are concentrically arranged.

The diameter of the circle where the inner circular arcs of all the elastic pieces 31 are located is larger than the diameter of the small head end of the truncated cone-shaped bulge 22 and smaller than the diameter of the large head end of the truncated cone-shaped bulge 22; therefore, under the normal state, the lower end part of the elastic sheet 31 is contacted with the middle part of the conical surface of the truncated cone-shaped bulge 22, so that the elastic sheet 31 is convenient to deform when the outer cover 3 is pressed down.

When in use, the inner cap 2 is pressed into the outer cap 3 in advance, and when the outer cap 3 is screwed, the 3 second slope protrusions 32 are arranged in the outer cap 3 and are engaged with the 3 first slope protrusions 23 on the inner cap 2, so that the inner cap 2 can be driven when the outer cap 3 is rotated, and the cap can be screwed.

When the cover is opened, the right side edge of the second inclined bulge 32 at the position of 3 and the first inclined bulge 23 at the position of 3 is an inclined plane. In normal opening, the contact between the inclined surface of the second ramp protrusion 32 and the inclined surface of the first ramp protrusion 23 may cause slippage, and the inner lid 2 may not be opened. At this time, the outer cap 3 is pressed down and a certain force is applied, the friction force at the contact position of the inclined surface of the second inclined protrusion 32 and the inclined surface of the first inclined protrusion 23 is increased, and the outer cap 3 drives the inner cap 2 when rotating and unscrews the inner cap 2 through the friction force. If the outer cover 3 is not pressed down during opening the cover or the pressing force is not enough, the inner cover 2 cannot be opened. If dangerous goods such as some chemicals, medicines or sharp utensils are stored in the storage tube 1, the storage tube structure of the utility model can prevent the children from opening by mistake.

The lower terminal surface middle part of enclosing cover 3 is equipped with 3 flexure strips 31, when enclosing cover 3 pressed down, flexure strip 31 can with the protruding 22 conical surface contact of round platform shape on the inner cup 2, flexure strip 31 is propped open and is produced deformation, provides a reaction force when pushing down enclosing cover 3 simultaneously for enclosing cover 3 needs certain dynamics just can press down, when loosening, the deformation of flexure strip 31 disappears, enclosing cover 3 resumes original position.

The utility model discloses be equipped with protruding 23 in first slope on inner cup 2, be equipped with the protruding 32 in second slope on outer cover 3, there is an inclined plane on the protruding 23 in first slope and the protruding 32 right side limit in second slope, when the lid is anticlockwise unscrewed, need press down tightly, if do not press enclosing cover 3 or the dynamics of pressing is not enough, enclosing cover 3 will skid, leads to the lid to open, can avoid the infant to open the lid by mistake.

The utility model discloses in, the protruding 23 in first slope is vertical face with the protruding 32 left side limit in second slope, and the protruding 23 in first slope meshes with the protruding 32 left side limit in second slope more easily, and the lid is not influenced when screwing clockwise, need not to press and just can screw the lid.

The utility model discloses there is the round to prevent falling protruding 33 in enclosing cover 3, and the inner cup 2 is blocked after embedding enclosing cover 3, can not fall out.
