Description

Technical Field

[0001] The utility model relates to the technical field of water cups, in particular to a threadless sealed water cup. Background Art

[0002] A water cup is usually a container for people to hold liquids, and can be used to drink tea, water, coffee, beverages, etc. The cup body of the water cup is mostly cylindrical and has a hollow structure with an open top. Because the top of the cup body is open, the liquid in the cup is easily contaminated by dust around it, and the heat preservation effect is poor, so a cup cover is often provided to cover the top opening.

[0003] Common forms of connection between the cup lid and the cup body include threaded connection or hinged connection. There is also a Chinese patent publication number CN117502880A, which is titled "A water cup with a non-threaded cup lid", in which the lid body is inserted into the opening of the cup body. When the lid body is inserted, the silicone convex ring fixed on the outer periphery of the lid body and the cup top convex ring at the cup mouth are transitionally matched to finally form a snap fit to achieve the connection between the cup lid and the cup body. In the connection structure of the cup lid and the cup body of the insert-cover type, the transition fit between the silicone convex rings is required during the insertion and removal of the lid body; therefore, in order to facilitate the insertion of the lid body into the opening of the cup body, the damping of the transition fit between the silicone convex rings cannot be too large, which also leads to the insufficient snap fit force of the snap fit formed between the silicone convex rings, and the cup lid is easily separated from the cup body when subjected to external force impact, so it is urgent to solve this problem. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a threadless sealed water cup, which, based on the connection form of the cup cover inserted into the opening of the cup body, not only retains the convenience of the connection formation, but also enables a good locking effect to be formed between the cup cover and the cup body.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A threadless sealed water cup comprises a cup body and a cup cover inserted into the opening of the cup body, wherein a bottom end of the cup cover is coaxially arranged with a chassis which can slide back and forth along its own axis, a rubber tube is connected between the top periphery of the chassis and the bottom periphery of the cup cover, and when the chassis is lifted and lowered, the rubber tube is driven to be in two states: an outward convex deformation and a straightened state, an inner flange is provided on the inner wall of the cup cover, and a locking mechanism is also provided on the cup cover, and after the rubber tube slides to below the inner flange, the locking mechanism can drive the chassis to rise and then lock, so that the rubber tube is in an outward convex deformation state, and finally the outward convex deformed rubber tube and the inner flange form a sealed snap fit.

[0007] As a further solution of the utility model: a hollow cavity is provided inside the cup cover, and the locking mechanism includes a sliding plate coaxially arranged in the hollow cavity and capable of sliding back and forth along its own axis, the sliding plate is fixedly connected to the chassis via a connecting column, an overlapping portion is fixed to the outer periphery of the sliding plate, and when the cup cover is inserted into the opening of the cup body, the end wall at the opening abuts against the overlapping portion to push the sliding plate and the chassis to slide upward; the locking mechanism also includes a locking portion for locking the sliding plate from sliding up and down.

[0008] As a further solution of the utility model: the locking part includes a hook fixed on the sliding plate, the cup cover is provided with a lock hook matched with the hook, and the lock hook is driven by an opening button and unlocked with the hook.

[0009] As a further solution of the utility model: the opening button slides elastically on the cup cover, and a driving wedge surface is provided on the opening button. The lock hook is elastically swung and installed in the hollow cavity through a horizontal axis, with the two ends of the lock hook being a locking end and an operating end respectively. The locking end cooperates with the hook, and the operating end cooperates with the driving wedge surface. When the opening button slides into the cup cover, the driving wedge surface squeezes the operating end of the lock hook, and makes the lock hook swing around the horizontal axis until its locking end is unlocked from the hook.

[0010] As a further solution of the utility model: a hook and a lock hook are used as a group of snap-fit ​​components, and the snap-fit ​​components are arranged to be a plurality of components axially evenly distributed around the axis of the sliding plate. The opening button is coaxially arranged on the top of the cup cover, and the opening button slides along its own axis and performs the unlocking action of all the snap-fit ​​components.

[0011] As a further solution of the utility model: a first return spring for elastically returning the squeeze lock hook is arranged in the hollow cavity.

[0012] As a further solution of the utility model: an elastic member for squeezing the sliding plate to slide downward is arranged in the hollow cavity.

[0013] As a further solution of the utility model: the connecting column coaxially passes through the sliding disk and is fixed to the sliding disk, a second return spring is sleeved on the column body of the penetrating section of the connecting column, two ends of the second return spring are respectively abutted against the opening button and the sliding disk, and the second return spring constitutes the elastic member.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. In the initial state, the rubber tube is in a straightened state. When the cup cover is inserted into the opening of the cup body, the friction between the outer wall of the rubber tube and the inner wall of the cup body is small or even non-existent. When the rubber tube slides to the bottom of the inner flange in the cup body, the locking mechanism can drive the chassis to rise and then lock, so that the rubber tube is in a convex deformed state, and finally the convex deformed rubber tube and the inner flange form a high-friction sealing snap fit. Therefore, based on the connection form of the cup cover inserted into the opening of the cup body, not only the convenience of the connection is retained, but also a good locking effect can be formed between the cup cover and the cup body.

[0016] 2. When the cup cover is inserted until the overlap part abuts against the end wall of the cup body opening, the rubber tube just slides to the bottom of the inner flange. At this time, the cup cover can be inserted further to push the sliding plate and the bottom plate to slide upward, and drive the rubber tube to deform outward to form a sealed snap fit with the inner flange. The above-mentioned sliding plate and overlap part can drive the rubber tube to deform outward only during the plug-in combination process of the cup cover and the cup body, without the need for additional operation, thus ensuring the convenience of plug-in combination of the cup cover and the cup body.

[0017] 3. The sliding plate is locked by combining a hook and a lock hook, and the lock hook is unlocked by pressing an open button. The operation is convenient and ensures the convenience of sliding and separating the cup cover and the cup body.

[0018] 4. The lock hook adopts the swing unlocking method and uses the lever principle. The driving wedge surface squeezes the operating end of the lock hook to achieve the swinging action, making the unlocking operation of the lock hook more labor-saving.

[0019] 5. The clamping components are arranged to be evenly distributed around the axis of the sliding disk. Different numbers of clamping components can be arranged according to the circumference of the sliding disk so that the sliding disk can be stably locked. In addition, the opening button is coaxially arranged on the top of the cup cover, and the opening button slides along its own axis and performs the unlocking action of all the clamping components, thereby ensuring the convenience of unlocking all the clamping components on the basis of ensuring the locking stability of the lock sliding disk.

[0020] 6. A first reset spring for elastically resetting the locking hook is arranged in the hollow cavity, which can be used to reset the locking hook by squeezing the spring. In addition, the locking stability between the locking hook and the hook can also be ensured by the reset squeezing force.

[0021] 7. An elastic member is provided in the hollow cavity to force the chassis and the sliding plate to slide downward as a whole. After the hook is unlocked, the chassis can slide downward under its own gravity and driven by the rubber tube. The elastic member increases the force for the chassis and the sliding plate to slide downward as a whole, ensuring that the chassis and the sliding plate can slide downward stably as a whole.

[0022] 8. The connecting column coaxially passes through the sliding plate and is fixed to the sliding plate. A second return spring is sleeved on the column body of the through section of the connecting column. The two ends of the second return spring are respectively in contact with the opening button and the sliding plate. The second return spring constitutes an elastic member. Therefore, the second return spring can not only drive the chassis to slide downward, but also assist the opening button to slide upward and return, ensuring that the opening button can be returned upward and stably.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] For ease of understanding, the specific structure and working mode of the utility model are further described below in conjunction with the accompanying drawings:

[0028] The specific structure of the utility model refers to Figure 1-2As shown, its main structure includes a cup body 10 and a cup cover 20 inserted into the opening of the cup body 10. Among them, a chassis 26 that can slide back and forth along its own axis is coaxially arranged at the bottom end of the cup cover 20, and a rubber tube 27 is connected between the top periphery of the chassis 26 and the bottom periphery of the cup cover 20; and when the chassis 26 is lifted and lowered, the rubber tube 27 is driven to be in two states: convex deformation and straightening. In addition, the inner wall of the cup cover 20 is provided with an inner flange 11, and a locking mechanism is also provided on the cup cover 20. In the initial state, the chassis 26 can slide downward under the elastic force of the rubber tube 27 and its own gravity. At this time, the rubber tube 27 is in a straightened state. In actual implementation, the outer diameter of the rubber tube 27 is set to be less than or equal to the inner diameter of the inner flange 11, so that when the cup cover 20 is inserted into the opening of the cup body 10, the friction between the outer wall of the rubber tube 27 in a straightened state and the inner wall of the cup body 10 is small or even no friction, which effectively reduces the resistance when the cup cover 20 is inserted into the opening of the cup body 10. After the cup cover 20 is inserted into the opening of the cup body 10 and the rubber tube 27 slides to the bottom of the inner flange 11, the locking mechanism can drive the chassis 26 to rise and then lock, so that the rubber tube 27 is in a convex deformation state, and finally the convexly deformed rubber tube 27 and the inner flange 11 form a high-friction sealing snap fit. The form of the sealing snap fit between the convexly deformed rubber tube 27 and the inner flange 11, based on the connection form of the cup cover 20 inserted into the opening of the cup body 10, not only retains the convenience of the connection, but also enables a good locking effect to be formed between the cup cover 20 and the cup body 10.

[0029] Furthermore, in order to improve the convenience of combining the cup cover 20 and the cup body 10, as Figure 1 As shown, a hollow cavity is provided inside the cup cover 20, and the locking mechanism includes a sliding plate 24 coaxially arranged in the hollow cavity and capable of sliding back and forth along its own axis, and the sliding plate 24 is fixedly connected to the bottom plate 26 through a connecting column 261. By setting the hollow cavity, the locking mechanism is built into the cup cover 20, thereby ensuring the integrity of the exterior of the cup cover 20. In addition, the driving components of the bottom plate 26 are also placed on the top through the sliding plate 24, providing a technical platform for operating the locking mechanism when the cup cover 20 is closed. Specifically, the outer periphery of the sliding plate 24 is fixed with an overlap portion 242. When the cup cover 20 is inserted into the opening of the cup body 10, the end wall of the opening abuts against the overlap portion 242. When in use, when the cup cover 20 is plugged into the overlap portion 242 and abuts against the end wall of the opening of the cup body 10, the rubber tube 27 just slides to the bottom of the inner flange 11. At this time, continuing to insert the cup cover 20 can push the sliding plate 24 and the bottom plate 26 to slide upward, and drive the rubber tube 27 to convexly deform outward to form a sealed snap fit with the inner flange 11. The above-mentioned setting of the sliding plate 24 and the overlap portion 242 can drive the rubber tube 27 to convexly deform outward only during the plug-in combination process of the cup cover 20 and the cup body 10, without generating additional operating actions, thereby ensuring the convenience of plug-in combination of the cup cover 20 and the cup body 10.

[0030] In addition, if Figure 1 As shown, the locking mechanism also includes a locking part for locking the sliding plate 24 to slide up and down, and the locking part includes a hook 241 fixed on the sliding plate 24. The cup cover 20 is provided with a lock hook 22 that matches the hook 241, and the lock hook 22 is driven by the opening button 21 and unlocked with the hook 241. The sliding plate 24 is locked in the form of the hook 241 matching with the lock hook 22, and the lock hook 22 is unlocked in the form of pressing the opening button 21, which is convenient to operate and ensures the convenience of sliding separation of the cup cover 20 and the cup body 10.

[0031] Specifically, Figure 1 As shown, the opening button 21 slides elastically on the cup cover 20, and a driving wedge surface 211 is provided on the opening button 21; the lock hook 22 is elastically swingably installed in the hollow cavity through the horizontal axis 221, with the two ends of the lock hook 22 being a locking end and an operating end respectively, the locking end cooperates with the hook 241, and the operating end cooperates with the driving wedge surface 211. When the opening button 21 slides into the cup cover 20, the driving wedge surface 211 squeezes the operating end of the lock hook 22, and makes the lock hook 22 swing around the horizontal axis 221 until its locking end is unlocked from the hook 241, thereby realizing that the opening button 21 drives the lock hook 22 to unlock from the hook 241. The lock hook 22 adopts a swing unlocking method, and uses the principle of lever, and the driving wedge surface 211 squeezes the operating end of the lock hook 22 to realize the swinging action, making the unlocking operation of the lock hook 22 more labor-saving.

[0032] Further, the locking stability of the sliding plate 24 is improved. Figure 1 As shown, a hook 241 and a lock hook 22 are used as a set of clamping components, and the clamping components are arranged as a plurality of components axially evenly distributed around the axis of the sliding plate 24. Different numbers of clamping components can be arranged according to the circumference of the sliding plate 24, so that the sliding plate 24 can be stably locked. In addition, the opening button 21 is coaxially arranged on the top of the cup cover 20, and the opening button 21 slides along its own axis and performs the unlocking action of all the clamping components, thereby ensuring the convenience of unlocking all the clamping components on the basis of ensuring the locking stability of the lock sliding plate 24.

[0033] Of course, the locking portion may also be implemented in other ways, such as using the shaft hole plug-in locking method commonly used in the prior art.

[0034] On the basis of the above, if Figure 1 As shown, a first return spring 23 for elastically returning the lock hook 22 is arranged in the hollow cavity, which can be used to return the lock hook 22 by the spring. In addition, the locking stability between the lock hook 22 and the hook 241 can also be ensured by the elastic return extrusion force.

[0035] In addition, an elastic member is provided in the hollow cavity to squeeze the sliding plate 24 to slide downward, so that after the hook 241 is unlocked, the chassis 26 can slide downward under its own gravity and the driving force of the rubber tube 27, and the elastic member can increase the force for the sliding plate 24 and the chassis 26 to slide downward as a whole, thereby ensuring that the sliding plate 24 and the chassis 26 can slide downward stably as a whole.

[0036] Specifically, the connecting column 261 coaxially passes through the sliding plate 24 and is fixed to the sliding plate 24. A second return spring 25 is sleeved on the column body of the through section of the connecting column 261. The two ends of the second return spring 25 are respectively in contact with the opening button 21 and the sliding plate 24. The second return spring 25 constitutes an elastic member. Therefore, the second return spring 25 can not only drive the chassis 26 to slide downward, but also assist the opening button 21 to slide upward and return, ensuring that the opening button 21 can be returned upward and stably.

[0037] Of course, for those skilled in the art, the present invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
