The invention discloses a medicament
bottle locking structure for preventing children from opening a medicament
bottle by accident. The medicament
bottle locking structure comprises a cover body and abottle body. The double-layer cover body is arranged, a first-stage inner rod and a first-stage sleeve are connected between an outer cover and an inner cover, a lower
piston is elastically supportedby a first-stage spring in a second-stage sleeve, so that the first-stage inner rod connected with an upper
piston is supported, and direct operation of the inner cover through the outer cover is avoided; a limiting bolt corresponding to a limiting
flange is circumferentially connected to a second-stage inner rod, a sliding sleeve and a traction rod are elastically supported by a second-stage spring, so that the circumferentially opened limiting bolt abuts against the limiting
flange, the cover body is limited in the bottle body, and the bottle body is prevented from being opened easily; through the gas or
liquid medium sealed between the first-stage sleeve and the second-stage sleeve, indirect
extrusion of a first-stage sliding rod to a second-stage sliding rod is realized, and the support of the second-stage sliding rod to a limiting ring is realized by utilizing the operation difficulty and the degree of
extrusion, so that it is guaranteed that the limiting bolt is easily contained.
