Description

Technical Field

[0001] The utility model relates to a container structure, in particular to a rotary container plug cover. Background Art

[0002] A container in the prior art includes an outer cover arranged outside the mouth of the container and a plug cover for plugging the mouth of the container. The outer cover can be used as a water cup during use. Therefore, when in use, the outer cover needs to be removed, and then the plug cover needs to be opened to pour out the liquid in the container, which is rather troublesome.

[0003] To solve the above problems, the Chinese utility model patent CN 211380959U discloses a heat-insulating kettle, in which a kettle plug for plugging the kettle mouth includes a body, a knob, a sealing cover, a cam mechanism and a temperature display module; a flow channel is arranged on the body, the knob is arranged at one end of the body, and the sealing cover is arranged at the other end of the body; the sealing cover can reciprocate along the axis direction of the body to open or close the flow channel; the cam mechanism is arranged in the body and connects the sealing cover and the knob. When the knob rotates, the sealing cover can be pushed to reciprocate along the axis direction of the body through the cam mechanism, and the temperature display module is arranged on the body for detecting and displaying the temperature. The cam mechanism includes a driving cam connected to the knob, a driven cam connected to the sealing cover and an elastic member for pushing the driven cam to reset. A wavy pushing surface is arranged on the driving cam, and a wavy contact surface adapted to the wavy pushing surface is arranged on the driven cam. An installation cavity is arranged on the body, and a positioning column is arranged in the installation cavity. Socket holes adapted to the positioning column are arranged on both the driving cam and the driven cam. The driving cam and the driven cam are both arranged in the installation cavity and are movably sleeved on the positioning column.

[0004] This technical solution sets a liquid flow channel on the plug cover and uses the driving cam and the driven cam to control the opening or closing of the liquid flow channel, thereby realizing pouring out the liquid from the container without pulling out the plug cover. However, in this solution, the knob and the cam structure are set to cooperate, and the user cannot distinguish when the sealing cover is opened and when it is closed, often resulting in misoperation, thinking that the sealing cover is closed, and as a result, when the outer cover is opened again during the next use, the liquid in the container has already overflowed. Moreover, in this technical solution, a return spring must be provided, otherwise the cam structure cannot realize its function of controlling the sealing cover, which means that once the spring has a problem, the plug cover may not be able to close the liquid flow channel. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a rotary container plug cover, which uses a screw lifting mechanism to realize the opening and closing of the liquid flow channel by the plugging part, and the user can judge the opening and closing state of the liquid flow channel according to the rotation direction of the knob.

[0006] To achieve the above object, the technical solution of the present utility model is as follows:

In addition, for the convenience of expression, some components in the drawings will be omitted, enlarged or reduced, but this does not represent the actual size or the entire structure of the product.

[0028] The present utility model discloses a rotary container plug cover, as Figures 1-4As shown in the figure, it includes a cover body 1, a blocking part 2, a lifting mechanism for controlling the lifting of the blocking part 2, and a knob 3 of the lifting mechanism; the cover body 1 is provided with a hollow installation cavity 12, and the lifting mechanism is arranged in the installation cavity 12; a liquid flow channel 11 is arranged at the bottom of the cover body 1, and the blocking part 2 is arranged at the bottom of the cover body 1 and can close or open the liquid flow channel 11; the lifting mechanism is a screw lifting mechanism, including a driving part 41 and a driven part 42, and the driven part 42 can rise or fall under the drive of the driving part 41.

[0029] A positioning column 13 is arranged in the installation cavity 12 of the cover body 1. Both the driving part 41 and the driven part 42 are provided with socket holes sleeved on the positioning column 13, and the driving part 41 and the driven part 42 are sleeved on the positioning column 13.

[0030] The knob 3 is connected to the driving part 41, and the driven part 42 is connected to the blocking part 2; the knob 3 controls the lifting of the lifting mechanism to drive the blocking part 2 to close or open the liquid flow channel 11.

[0031] As Figure 3 、 Figure 4 shown in the figure, the lifting mechanism includes a driving part 41 and a driven part 42. The driving part 41 is in the shape of a hollow cylinder, and a spiral chute 411 is arranged on the cylinder wall of the driving part 41 from top to bottom; correspondingly, the driven part 42 is set as a columnar shape adapted to the hollow cylinder shape of the driving part 41, and a convex part 421 adapted to the chute 411 of the driving part 41 is arranged on the upper part of the outer wall of the driven part 42, and the convex part 421 is arranged in the chute 411. Usually, the convex part 421 is set as a columnar shape to facilitate the assembly of the driven part 42 and the driving part 41.

[0032] A limiting part 412 adapted to the convex part 421 of the driven part 42 is arranged on the driving part 41. Preferably, the limiting part 412 is arranged at the end of the chute 411.

[0033] Preferably, the chute 411 is arranged on the inner wall of the driving part 41 and is a groove recessed from the inner wall; further, two symmetrically arranged chutes 411 are arranged on the inner wall of the driving part 41.

[0034] Or, as Figure 4 shown in the figure, the chute 411 is a hollow slideway arranged on the driving part 41. Further, the chute 411 is two hollow and symmetrically arranged slideways arranged on the driving part 41.

[0035] The chute 411 spirally extends downward along the cylinder wall from the upper part of the driving part 41, and each chute 411 winds around the cylinder wall for half a week. Therefore, the two chutes 411 are symmetrically arranged.
