Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the specific embodiments.

As shown in fig. 1 and 2, the stopper body 1 for closing a bottle opening of the present invention further includes a spindle 2 penetrating through the stopper body 1; the lower end of the main shaft 2 is connected with a locking device for locking the plug body 1 at the bottle opening, and the main shaft 2 moves up and down to drive the locking device to open or close; the password system is arranged on the main shaft 2, and the main shaft 2 can move up and down only after the password system receives a correct password.

Specifically, the password system comprises an upper password sheet 3, a middle password sheet 4 and a lower password sheet 5 which are sequentially sleeved on a main shaft 2 from top to bottom; gaskets 13 are arranged between the upper password sheet 3 and the middle password sheet 4 and between the middle password sheet 4 and the lower password sheet 5. The main shaft 2 is provided with a convex block 17, and the upper password sheet 3, the middle password sheet 4 and the lower password sheet 5 are provided with notches through which the convex block 17 passes; the upper password sheet 3 and the middle password sheet 4 are both provided with an unclosed annular groove 14, and the middle password sheet 4 and the lower password sheet 5 are both provided with an upright post 15; the upright post 15 on the middle password piece 4 penetrates through the annular groove 14 of the upper password piece 3, and the upright post 15 on the lower password piece 5 penetrates through the annular groove 14 of the middle password piece 4; the lower code plate 5 is sleeved on the main shaft 2 by a sleeve 16, and the sleeve 16 extends out of the plug body 1. The part of the sleeve 16 extending out of the cock body 1 is fixedly sleeved with a knob 19 for driving the sleeve 16 to rotate. The top surface of the plug body 1 is marked with code scales around the sleeve 16.

The locking device comprises an annular chassis 10, and a plurality of clamping jaws 11 are arranged at the bottom of the chassis 10; the claws 11 are 3 evenly distributed along the circumference. The clamping jaw 11 is connected with the chassis 10 by using the mounting seat 12 and a rotating shaft on the mounting seat, so that the clamping jaw 11 can be turned over up and down; the lower end of the main shaft 2 is provided with a piston head 18, and when the piston head 18 extends into an inner hole of the chassis 10, the inner end of the clamping jaw 11 is pressed, so that the outer end of the clamping jaw 11 is tilted. An outer shell 6 is connected below the plug body 1, and an inner shell 7 is fixed above the chassis 10; the outer side of the inner shell 7 is provided with a tenon 9, and the outer shell 6 is provided with a mortise 8 which is matched and connected with the tenon 9. The lower part of the main shaft 2 is movably sleeved with a connecting ring 20 above the piston head 18, and the connecting ring 20 is matched and connected with the inner shell 7. The connection ring 20 is preferably made of silicone and is interference fit with the inner housing 7.

When the plug body 1 is used, if the plug body is required to be taken down from a bottle opening, the plug body is required to be operated by the knob 19 to rotate 2 circles of the lower password sheet 5 anticlockwise, the upright post 15 on the lower password sheet 5 is inserted into the annular groove 14 of the middle password sheet 4 to drive the middle password sheet 4 to rotate, and the position of the middle password sheet 4 is initialized, namely the upright post 15 on the middle password sheet 4 is just positioned at the end of the annular groove 14 of the upper password sheet 3. The lower code plate 5 is then rotated further counter clockwise to the first code, at which point the upper code plate 3 has reached the correct position. And rotating the lower password sheet 5 clockwise for a circle to initialize the middle password sheet 4, and then continuing rotating clockwise to the position of a second password to ensure that the notch of the middle password sheet 4 is just opposite to the notch of the upper password sheet 3. And then, directly rotating the lower password piece 5 to a third password position anticlockwise so that the gaps of the lower three password pieces are overlapped. And finally, rotating the main shaft 2 to a fourth password position to enable the bump 17 of the main shaft 2 to be superposed with the notches of the three password sheets, namely, pulling up the main shaft 2 to enable the piston head 18 at the lower end of the main shaft 2 to be separated from the inner end of the claw 11. Due to the loss of the compression of the piston head 18, the outer ends of the claws 11 naturally droop under the action of gravity so that the claws 11 contract, and the stopper body 1 is separated from the bottle mouth.

If the plug body 1 needs to be locked at the bottle opening, the password is input as the plug body 1 is taken, the main shaft 2 is pulled out after the password pieces are rotated to the correct positions, the clamping jaws 11 are folded, and then the plug body 1 is plugged into the bottle opening. The main shaft 2 is pressed down to plug the connecting ring 20 into the inner shell 7, so as to achieve the sealing effect and prevent water leakage. At the same time, the piston head 18 at the lower end of the main shaft 2 presses the inner ends of the claws 11 to tilt and expand the outer ends. Finally, all the passwords are disordered by rotating the lower password sheet 5, and the plug body 1 is locked at the bottle mouth.

The principle of the coded lock is adopted, unlocking can be achieved without a key or electronic equipment, and the coded lock is convenient and practical.

The above is only a preferred embodiment of the present invention, and it should be noted that the above preferred embodiment should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and enhancements can be made without departing from the spirit and scope of the invention, and such modifications and enhancements are intended to be within the scope of the invention.
