Description

Technical Field

[0001] The utility model relates to the technical field of water cup lids, and particularly relates to an inner limiting structure of a rotary opening type cup lid. Background Art

[0002] A cup is a container for holding liquids that is often used in daily life and can be used for drinking tea, water, beverages, etc. Chinese Patent CN 217771976U discloses a pop-up lid type double drinking water cup, which successively includes a main lid body connected to the cup body from bottom to top, an intermediate lid body equipped with an upper straw, and a top lid for closing the upper straw. The rear end of the intermediate lid body is rotatably connected to the main lid body through a rotating shaft, the front end of the intermediate lid body is connected to the main lid body through a first locking block, the rear end of the top lid is rotatably connected to the intermediate lid body through a rotating shaft, and the front end of the top lid is connected to the intermediate lid body through a second locking block; however, when this water cup is mixed with other objects and moved, there is a risk that the locking block may be accidentally opened by being hit by other objects.

[0003] Based on this, the utility model proposes an inner limiting structure of a rotary opening type cup lid. Summary of the Utility Model

[0004] Aiming at the deficiencies of the above-mentioned prior art, the utility model provides an inner limiting structure of a rotary opening type cup lid to solve the above technical problems.

[0005] An inner limiting structure of a rotary opening type cup lid includes a cup lid main body and a top lid. The cup lid main body is provided with a drinking port. The rear end of the top lid is connected to the cup lid main body through a rotating shaft. The front end of the cup lid main body is rotatably sleeved with a knob. The rear end of the knob is fixedly connected with an inner limiting block. The front end of the top lid is fixedly connected with a mirror-image L-shaped blocking block. The top lid is slidably sleeved with an indicating block above the left upper part of the mirror-image L-shaped blocking block. The indicating block is fixedly connected with a return spring;

[0006] Turn the top lid downward to close it, and rotate the knob clockwise. The rear inclined surface of the inner limiting block pushes the indicating block to slide backward until the inner limiting block is completely abutted against the mirror-image L-shaped blocking block. The rear inclined surface of the inner limiting block is separated from the indicating block, and the return spring pushes the indicating block to slide forward;

[0007] Press the inner limiting block backward and rotate the knob counterclockwise to open the top lid.

[0008] Further, the indicating block includes a sliding part and an extending part. The top lid is provided with a sliding groove that matches the sliding part. The rear end of the return spring is fixedly connected to the sliding groove. The bottom end of the sliding groove is provided with a through channel that matches the extending part.

[0009] Further, the through channel is provided with an anti-slip end, and the extending part abuts against the anti-slip end, and the sliding part stops sliding forward.

[0010] Further, the knob is provided with a convex handle.

[0011] Further, the top cover is provided with a retaining post that cooperates with the drinking port, and the retaining post is coated with food-grade silica gel.

[0012] Due to the adoption of the above technical solutions, compared with the prior art, the beneficial effects of the present utility model include:

[0013] When the top cover is closed, the inner limit block is in full contact with the mirror L-shaped stop block. The inner limit block restricts the mirror L-shaped stop block, that is, the inner limit block restricts the top cover. At the same time, under the action of the return spring, the extension part of the indicating block prevents the knob from rotating in the reverse direction; and when the indicating block is hit by other objects, the return spring can play a buffering role to keep the closed state of the top cover stable.

[0022] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other implementation manners or equivalent replacements obtained by those skilled in the art without creative efforts are within the protection scope of the present invention.

[0023] As Figures 1-7 shown, an inner limit structure of a rotary opening cup cover includes a cup cover body 1 and a top cover 2. The cup cover body 1 is threadedly connected to the cup body. The cup cover body 1 is provided with a drinking port. The rear end of the top cover 2 is connected to the cup cover body 1 through a rotating shaft. A torsion spring is installed on the rotating shaft. A knob 3 is rotatably sleeved at the front end of the cup cover body 1. A rear end of the knob 3, that is, an end facing the drinking port, is fixedly connected to an inner limit block 4. A mirror-image L-shaped stop block 5 is fixedly connected to the front end of the top cover 2. An indicating block 6 is slidably sleeved above the left upper part of the mirror-image L-shaped stop block 5, that is, as Figure 4 shown, a sliding part of the indicating block 6 and a chute 8 are located above the left upper part of the mirror-image L-shaped stop block 5. A return spring 7 is fixedly connected to the sliding part of the indicating block 6;

[0024] Turn the top cover 2 downward to close it, and rotate the knob 3 clockwise. The rear inclined surface of the inner limit block 4 pushes the extending part 11 of the indicating block 6 to slide backward until the inner limit block 4 is completely in contact with the mirror-image L-shaped stop block 5. The rear inclined surface of the inner limit block 4 is separated from the extending part 11 of the indicating block 6. The return spring 7 pushes the indicating block 6 to slide forward. At this time, the extending part 11 of the indicating block 6 restricts the inner limit block 4 to prevent the knob 3 from rotating in the reverse direction;

[0025] Press the inner limit block 4 backward and rotate the knob 3 counterclockwise to open the top cover 2.

[0026] Among them, the indicating block 6 includes a sliding part and an extending part 11. The chute 8 is matched with the sliding part. The rear end of the return spring 7 is fixedly connected to the chute 8. A through channel matched with the extending part 11 is provided at the bottom end of the chute 8.

[0027] Among them, the through channel is provided with an anti-slip end. The extending part 11 abuts against the anti-slip end, and the sliding part stops sliding forward.

[0028] Among them, the knob 3 is provided with a convex handle 9, and it is convenient to rotate the knob 3 through the convex handle 9.

[0029] Among them, the top cover 2 is provided with a retaining post 10 matched with the drinking port. The retaining post 10 is coated with food-grade silica gel. After the top cover 2 is closed, the retaining post 10 prevents the liquid in the cup from flowing out of the drinking port.

[0030] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to only the specific embodiments. Obviously, many modifications and variations can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the relevant technical field can well understand and utilize the present utility model. The present utility model is only limited by the claims and their full scope and equivalents.
