Water cup with coded lock

Abstract

The invention relates to a water cup with a coded lock, and relates to the technical field of water cups with coded locks, a cup body and a built-in heat preservation plug are connected through threads, and the built-in heat preservation plug is rotated in the anticlockwise direction to be screwed and connected; the cup body and the cup cover provided with the coded lock are connected through threads, and the cup cover provided with the coded lock is rotated in the clockwise direction to be connected in a screwed mode. The cup cover provided with the coded lock and the built-in heat preservation plug are connected through the spring bolt and the hole groove, the cup cover provided with the coded lock must be rotated in the anticlockwise direction when the cup cover needs to be opened, and under the condition that an unlocking password is not used, due to the fact that the cup cover and the built-in heat preservation plug are connected into a whole through the spring bolt, the cup cover can be opened. The built-in heat preservation plug needs to rotate anticlockwise along with the cup cover, at the moment, the built-in heat preservation plug cannot rotate anticlockwise any more, the built-in heat preservation plug is screwed anticlockwise to be connected with the cup body, and the built-in heat preservation plug and the cup body can be combined more tightly when the built-in heat preservation plug rotates anticlockwise. Due to the fact that the cup cover is arranged on the cup body, the cup cover is limited to rotate in the anticlockwise direction, the cup cover cannot be moved away from the cup body, meanwhile, the situation that a user of the water cup is hurt by malicious behaviors of an unwanted person is avoided, and drinking water safety guarantee is provided for the user of the water cup.

Description

Technical Field

[0001] The present invention relates to the technical field of water cups with password locks, and more particularly to a water cup with a safe and reliable password lock, in order to prevent a user of the water cup from being poisoned, drugged or played a prank by a malicious person after the user of the water cup leaves the cup's sight and to avoid causing personal injury to the user of the water cup. Background Art

[0002] At present, the cups that people use for drinking water can be opened by anyone at any time and anywhere, and there is no function to protect the safety of the user of the cup. This provides malicious people with an opportunity to do bad things, which can easily cause personal injury. In order to prevent such incidents from happening, it is very important to develop a cup with a password lock. Summary of the invention

[0003] In order to improve the safety and reliability of drinking water in a cup used by people in daily life, the present invention provides a cup with a password lock. The cup can fully ensure that the water in the cup will not be intentionally contaminated by human beings when the user is out of sight of the cup, ensuring that the user of the cup can drink the water in the cup safely and assuredly.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a thread is formed at the outer edge of the upper opening of the cup body, which is consistent with the thread of the inner opening of the cup cover and can enable the cup cover to be tightened with the cup body in a clockwise direction; a thread is formed at the inner edge of the upper opening of the cup body, which is consistent with the thread on the lower half of the built-in thermal insulation plug of the cup opening and can enable the built-in thermal insulation plug to be tightened with the cup body in a counterclockwise direction; the upper half of the built-in thermal insulation plug is a cylinder with only a bottom, and the diameter of the bottom is equal to the diameter of the outer edge of the upper opening of the cup body; two holes are opened on the cylinder so that they are parallel to each other and on the same horizontal line; a manual password lock is installed on the cup cover, and the lock has two lock tongues, one on the left and one on the right, which are parallel to each other and on the same horizontal line, and the size and direction of the lock tongues just match the two holes on the built-in thermal insulation plug. Before the user of the water cup leaves the sight of the water cup, he only needs to connect the built-in insulation plug with the cup body and tighten it, then connect the cup cover with the cup body and tighten it, and dial the password of the lock on the cup cover. At this time, the two lock tongues enter the two corresponding holes on the built-in insulation plug. At this time, the user of the water cup can scramble the password set by himself, and the cup cover and the cup body can be locked, making them inseparable. Since the built-in thermal insulation plug is connected to the cup body by screwing it counterclockwise, and the cup cover is connected to the cup body by screwing it clockwise, the cup body, the built-in thermal insulation plug and the cup cover are firmly locked together by the locking tongue. Without using the unlocking password, the cup cover and the cup body cannot be separated intact. Because if you want to open the cup cover, you must rotate the cup cover counterclockwise. Since the cup cover is connected to the built-in thermal insulation plug through the locking tongue, the built-in thermal insulation plug must also rotate counterclockwise with the cup cover at this time, and the built-in thermal insulation plug cannot rotate counterclockwise anymore, because the built-in thermal insulation plug is connected to the cup body by screwing it counterclockwise. The more it rotates counterclockwise, the tighter and more firmly the built-in thermal insulation plug and the cup body will be combined. Therefore, the cup cover is restricted from rotating counterclockwise, making it impossible to remove the cup cover from the cup body, thereby providing drinking water safety for the user of the water cup, and at the same time avoiding the malicious behavior of ill-intentioned people from causing harm to the user of the water cup.

[0005] The beneficial effect of the present invention is that it blocks malicious acts such as poisoning or drugging the cup of the user of the water cup, and ensures that the user of the water cup can drink the water in his cup with peace of mind. The present invention is easy to operate and has high safety. BRIEF DESCRIPTION OF THE DRAWINGS
