Specific embodiment

A kind of antitheft upper cover of tank body, referring to Fig. 1: including tank body 1, upper cover 3 and position-limit mechanism, upper cover 3 passes through Screw assembly It is connected to 1 upper end of tank body, along being equipped with boss 2 on 1 inner wall of tank body, the upper surface is evenly distributed with several limiting slots, in upper cover 3 Portion is equipped with the limited post 6 of longitudinal sliding motion assembly, and 3 lower end of upper cover is equipped with the perforation of corresponding limited post 6, and perforation top is equipped with corresponding limit The assembly cavity of position mechanism；Position-limit mechanism is the cock body 4 by Screw assembly in assembly cavity, and 4 upper end of cock body is equipped with along it The fluting that diameter extends, the similar screw upper surface of slotting；6 upper end of limited post is equipped with the flange of corresponding perforation, the flange The first spring 5 is equipped between cock body 4,6 outer wall of limited post is equipped with the second spring 7 of companion flange and assembly cavity bottom；Assembly Chamber upper end extends to 3 upper surface of upper cover, and 3 end of upper cover is equipped with the frangible paster of corresponding assembly cavity.

No less than two limiting slots are evenly distributed on 2 upper surface of boss.The limit trench bottom is threadingly revolved close to upper cover 3 Direction one is sloped downwardly to form ratchet out.

Further, 2 upper surface of boss cover one layer of rubber waterproof circle, when upper cover 3 compress when, can be to tank body 1 inside Seal waterproof.

The tank body 1 is glass material, corresponding, and upper cover 3 can also be glass material or plastic material, if metal material Matter, it is tiny more than the inner body structure of upper cover 3 and tank body 1, it as time went on, can be because of the inner body caused by Structural wear and get rusty, it is unfavorable for the preservation of food.

The working principle of the utility model is: setting limited post 6, limits upper cover 3 by limited post 6 and limiting slot Position to guarantee that upper cover 3 will not be by turn, and then guarantees the safety of interior items.First spring, 5 spring ratio is greater than second 7 spring ratio of spring, turn upper cover 3, limited post 6 can be squeezed power effect along limiting slot basal sliding, to guarantee that upper cover 3 can To screw, after upper cover 3 screws, the first spring 5 squeeze limited post 6 enter limiting slot, limit trench bottom close to upper cover 3 threadingly It screws out direction one to be sloped downwardly to form ratchet, can guarantee that upper cover 3 is limited by limited post 6 without being opened under conventional sense； Cock body 4 is set, and by turn cock body 4 of slotting, after cock body 4 screws out, the first spring 5 is ineffective, and second spring 7 drives limit Column 6 exits limiting slot, to unlock.

Further, in order to facilitate the fluting of 4 upper end of user's turn cock body, in another embodiment, such as Fig. 3 institute Show, airbag structure 8 is arranged on cock body 4, and the airbag structure 8 includes the first fixinig plate 81, air bag body 82 and the second fixinig plate 83, the both ends of the air bag body 82 are fixed as one with first fixinig plate 81 and the second fixinig plate 82 respectively, and described first The outer end face of fixinig plate 81 is equipped with connector, is fixedly connected with cock body 4, and the connector on first fixinig plate is 3M glue Piece.

Preferably, the air bag body 82 is cylindrical-shaped structure, and the air bag body 82 has multiple foldable layers, and wherein one A foldable layer is equipped with air hole, and when air bag body 82 is in compressive state, foldable layer can successively folding shrinking.When air bag body 82 is logical Cross air hole inflation be saturation state when, cylindrical-shaped structure multiple foldable layers expansion.Fig. 3 show airbag structure and is in compression Schematic diagram when state, Fig. 4 show the schematic diagram that airbag structure is under inflated condition.When in use, user can be by disk Multiple foldable layers of shape structure pull open, and making the inflation of air bag body 82 is saturation state, increase the contact area of hand and airbag structure, side Just the hand of user is extracted 4 turn of cock body by elongated air bag body 82.Second fixinig plate 83 is stiff lightweight material, makes hand Referring to has enough stress points, facilitates torsion air bag body 82, while driving the cock body 4, Jin Erxuan being fixedly connected with air bag body 82 Dynamic cock body 4.

Frangible paster is set, and people can judge whether upper cover 3 is opened by observing frangible paster, be further ensured that safety Property.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change It also should be regarded as the protection scope of the utility model into modification.
