Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a quick-switching device for use between a container and a lid. Background Technology

[0002] A water cup is a tool used by people to drink water. For ease of carrying and use, most existing water cups consist of a cup body and a cup lid. The cup lid and the cup body are usually connected by threads. In order to improve the heat preservation effect, the threaded connection between the cup lid and the cup body is often designed to be very tight. Opening or closing the water cup is relatively troublesome, and because it requires a lot of rotation, it is easy to cause incomplete closure and leakage. Therefore, more and more quick-opening water cups are incorporating existing water cup technologies. For example, the quick-opening structure of the water cup disclosed in CN219460819U and the portable opening water cup utilize a locking assembly between the outer and inner shells of the lid. When the lid needs to be opened, pressing the locking element moves the lid away from the cup body. During this process, the controlled movement of the locking element pushes the rotating actuating element to retract the latch of the fastening element into the inner shell, thereby releasing the latching connection between the latch and the positioning groove at the cup opening. This allows for quick opening of the lid with one hand. Moreover, when the lid needs to be closed, simply moving the lid and the cup body in opposite directions allows the latch to re-engage with the positioning groove, making opening and closing the lid equally convenient and quick. However, water cups that can be opened simply by pressing also pose a risk of accidental opening. Summary of the Invention

[0003] The purpose of this invention is to provide a quick-opening and closing device. This invention utilizes the upward restoring elastic force of the main spring to drive the locking member to move horizontally to below the horizontal protrusion to form a stable locking structure, thereby locking the lid at the container opening position and realizing quick opening and closing of the container and lid.

[0004] To solve this technical problem, the technical solution of this utility model is: a quick-opening device, which is disposed on a cover that is locked together and a container with an opening; the opening of the container is provided with a horizontal protruding edge; The cover body includes, from bottom to top, an inner cover that coaxially closes the container opening, a main spring, a mounting bracket, and a top cover; At least two locking elements are installed on the corresponding horizontal protrusion between the inner cover and the mounting bracket; The main spring, under its own upward restoring force, drives the mounting bracket to move upward. The mounting bracket, moving upward from bottom to top, pushes the locking element that penetrates the inner cover to protrude from the lower end of the inner cover and the horizontal convex edge, forming a locking contact.

[0005] Further improvements include a pop-up assembly, which includes a positioning frame coaxially arranged with the mounting bracket and a pop-up spring; a plurality of mounting seats for mounting the positioning pop-up spring are arranged sequentially along the circumferential direction of the positioning frame, the mounting seats corresponding to the horizontal protrusion of the container; the pop-up spring is located between the top cover and the mounting seat.

[0006] In a further improvement, the top cover is provided with a positioning sleeve facing the mounting base, the mounting base is provided with a positioning post nested with the positioning sleeve, and the spring is installed in the mounting base through the positioning sleeve.

[0007] In a further improvement, the mounting base has a post on the side facing the inner cover, passing through the inner cover and corresponding to the horizontal flange of the container. The spring-loaded assembly in this invention effectively ensures the spring-loaded effect through the interaction between the post and the horizontal flange. When the connection between the top cover and the mounting bracket is released, the post, under the action of the spring-loaded spring, releases elasticity from the upper surface of the horizontal flange of the container, causing the cover to separate upwards from the container.

[0008] In a further improvement, the mounting bracket has a push protrusion on the side facing the locking member, corresponding to the locking member one-to-one. In this invention, when the cover and container are not locked and the main spring is in its natural extension / retraction state, the push protrusion is positioned to push the locking member out of the mounting hole. When the main spring is compressed by external pressure, the mounting bracket moves downward relative to the inner cover fixed to the container opening. The push protrusion protruding from the inner wall of the mounting bracket moves below the locking member as the main spring shortens. The locking member moves within the mounting gap between the inner wall of the mounting bracket and the inner cover, ensuring reliable pushing and contact between the mounting bracket and the locking member. Furthermore, the width of the gap between the mounting bracket and the inner cover ensures that the locking member is essentially positioned within the mounting hole through which the inner cover passes.

[0009] In a further improvement, the inner cover includes a recessed portion extending into the container to cover the opening, a support portion for contacting the container opening, and a limiting portion extending from the support portion towards the lower end of the mounting bracket. The inner cover of this invention has a continuous structure; the recessed portion and the support portion effectively cover the container opening. Furthermore, the continuously extending portion of the inner cover is used to create a through-hole for the mounting bracket and the horizontal flange of the container to form a snap-fit ​​positioning, thereby locking the cover tightly to the container opening.

[0010] In a further improvement, the mounting bracket is fixed with a driving component for applying downward pressure along the circumferential direction, and the surface of the driving component is provided with an anti-slip structure. This invention facilitates contact with fingers and provides anti-slip properties by incorporating a driving component.

[0011] In a further improvement, the diameter of the mounting hole facing the mounting bracket is D1, and the diameter of the hole facing the container is D2, where D1 is larger than D2. This invention, by setting mounting holes with different opening sizes at both ends, ensures that the locking element is installed between the inner cover and the side wall of the mounting bracket. When the mounting bracket moves downward relative to the inner cover as the main spring compresses, moving away from the locking element, the locking element, guided by the structure of the mounting hole, rolls along the mounting hole towards the mounting bracket and retracts into the mounting hole, preventing contact with the horizontal flange when the cover moves away from the container.

[0012] In a further improvement, the locking element is a rigid ball. The locking ball with a rigid spherical structure in this invention effectively ensures stable clamping of the locking element between the mounting bracket and the horizontal flange of the container, guaranteeing a stable locking connection between the lid and the container.

[0013] A further improvement includes a positioning mechanism located between the top cover and the mounting bracket, which, as the cover and container reach the locking position, forms an interlocking connection to keep the mounting bracket in the locked position. The positioning mechanism includes connecting protrusions that extend towards each other from the top cover and the mounting bracket, respectively, and interlock or separate by rotation.

[0014] By adopting the above technical solution, the beneficial effects of this utility model are: This invention utilizes a cover body, consisting of an inner cover, a main spring, a mounting bracket, and a top cover arranged coaxially from bottom to top, along with a horizontal flange of the container opening. When the cover body is not closed at the container opening and both the spring-loaded spring and the main spring in the spring-loaded assembly are in their naturally extended state, the locking element driven or actuated by the mounting bracket is in a position suitable for axially engaging with the horizontal flange. When the cover body is closed at the container opening, the recessed portion of the inner cover extends into the container opening, and the support portion of the inner cover corresponds to the horizontal flange. At this time, the mounting bracket supports the container. The horizontal flange and mounting bracket compress the main spring under downward force. When the downward force is removed, the main spring returns to its natural length. The locking element moves upward with the mounting bracket and abuts against the horizontal flange from below, locking the lid to the container along the circumference. Then, further downward pressure causes the top cover to spring back and retract, rotating the positioning mechanism. The mounting bracket, inner cover, and the horizontal flange of the container form rigid mechanical contact in the axial direction of the container. The top cover and mounting bracket, and the mounting bracket are locked and positioned axially by the locking element and the horizontal flange, thus ensuring a tight seal between the lid and the container. When the lid needs to be opened, the rotation positioning mechanism is adjusted until the top cover and mounting bracket are in an unconnected position, releasing the mutual restraint between the mounting bracket and the top cover. The mounting base can move between the top cover and the mounting bracket as the spring extends, releasing the rigid contact. The mounting bracket is pulled down, and the locking element can move away from the horizontal flange, releasing the contact between the locking element and the horizontal flange. At the same time, the spring of the spring-lifting assembly acts on the horizontal flange through its own length change, causing the lid to detach from the horizontal flange and the container, forming a bouncing effect, which is equivalent to opening the lid by rotating horizontally.

Detailed Implementation

[0017] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0018] This embodiment discloses a fast switching device, such as... Figures 1 to 12 As shown, a cover 100 and a container 200 with an opening are provided for mutual locking and sealing. The opening of the container 200 is provided with a horizontal protrusion 210. The cover 100 includes, from bottom to top, an inner cover 1 that covers the opening of the container 200, a main spring 2, a mounting bracket 3, and a top cover 4, which are coaxially arranged to cover the opening of the container 200. At least two locking elements 5 are evenly installed along the circumference of the horizontal protrusion 210 between the inner cover 1 and the mounting bracket 3. When the main spring 2 is subjected to a downward external force, it contracts until the mounting bracket 3 moves upward relative to the inner cover 1 to the locking position between the cover 100 and the container 200. The mounting bracket 3 pushes the locking element 5 through the inner cover 1 to protrude out of the inner cover 1 and form an abutment with the lower end of the horizontal protrusion 210. The cover 100 also includes a positioning mechanism 6 provided between the top cover 4 and the mounting bracket 3, which forms an interlocking connection between the cover 100 and the container 200 as they reach the locking position, keeping the mounting bracket 3 in the locking position.

[0019] This embodiment also includes a pop-up assembly 7, which includes a positioning frame 71 coaxially arranged with the mounting bracket 3 and a pop-up spring 72. Multiple mounting seats 73 for mounting the pop-up spring 72 are sequentially arranged along the circumference of the positioning frame 71, and the mounting seats 73 correspond to the horizontal protrusion 210 of the container 200. The pop-up spring 72 is located between the top cover 4 and the mounting seats 73. In this embodiment, when the main spring 2 loses its limit and returns to its initial state, the pop-up assembly 7 utilizes the restoring deformation of the pop-up spring 72, combined with the restoring deformation stroke of the main spring 2, to enhance the relative separation speed between the pop-up assembly 7 and the horizontal protrusion 210 of the container 200, creating a pop-up effect when the lid is opened, providing a clear indication of opening.

[0020] In this embodiment, the top cover 4 is provided with a positioning sleeve 41 facing the mounting base 73, and the mounting base 73 is provided with a positioning post 731 nested with the positioning sleeve 41. The spring 72 is installed in the mounting base 73 through the positioning sleeve 41.

[0021] In this embodiment, the mounting base 73 has a post 732 on the side facing the inner cover 1, which passes through the inner cover 1 and corresponds to the horizontal protrusion 210 of the container 200. In this embodiment, the pop-up assembly 7 interacts with the horizontal protrusion 210 through the post 732, effectively ensuring the pop-up effect produced by the pop-up spring 72 restoring its deformation.

[0022] In this embodiment, the mounting bracket 3 has a push protrusion 32 on the side facing the locking member 5, which corresponds to the locking member 5. In this embodiment, when the cover 100 and container 200 are not locked and the main spring 2 is in its natural extension state, the push protrusion 32 is located below the locking member 5. When the main spring 2 is shortened by external pressure, the mounting bracket 3 moves upward relative to the inner cover 1 fixed to the opening of the container 200. The push protrusion 32 protruding from the inner wall of the mounting bracket 3 moves from below the locking member 5 in the mounting gap between the inner wall of the mounting bracket 3 and the inner cover 1 as the main spring 2 shortens, ensuring that the mounting bracket 3 and the locking member 5 are reliably pushed and contacted. On the other hand, when the main spring 2 is in its natural extension state, the width of the gap between the mounting bracket 3 and the inner cover 1 can ensure that the locking member 5 is basically located in the mounting hole 14 through which the inner cover 1 passes, avoiding relative movement between the cover 100 and the horizontal protrusion 210 and obstruction of the horizontal protrusion 210. When the mounting bracket 3, the top cover 4, and the horizontal flange 210 of the container 200 are in the locked position and the positioning mechanism 6 works together with the horizontal flange 210 to fix the compression state of the main spring 2, the locking member 5, which is arranged along the circumference of the horizontal flange 210, is pressed down on the horizontal flange 210 under the push of the mounting bracket 3, thereby forming the cover 100 axially positioned relative to the horizontal flange 210 of the container 200, realizing the sealing and locking of the cover 100 and the container 200.

[0023] In this embodiment, the inner cover 1 includes a recessed portion 11 extending into the container 200 to cover the opening, a support portion 12 for contacting the opening of the container 200, and a limiting portion 13 extending from the support portion 12 toward the lower end of the mounting bracket 3. The inner cover 1 of this embodiment has a continuous structure. The recessed portion 11 and the support portion 12 effectively cover the opening of the container 200. Furthermore, the continuously extending limiting portion 13 of the inner cover 1 is used to create a through-hole for the mounting bracket 3 and the horizontal protrusion 210 of the container 200 to engage and position, thereby locking the cover 100 at the opening of the container 200.

[0024] In this embodiment, the mounting bracket 3 is fixed with a driving component 31 for applying downward pressure along the circumferential direction. The surface of the driving component 31 is provided with an anti-slip structure. This embodiment facilitates contact with fingers and prevents slippage by providing the driving component 31.

[0025] In this embodiment, the diameter of the mounting hole 14 facing the mounting bracket 3 is D1, and the diameter of the mounting hole facing the container 200 is D2, where D1 is larger than D2. This embodiment ensures that the locking member 5 is installed between the inner cover 1 and the side wall of the mounting bracket 3 by setting mounting holes 14 with different opening sizes at both ends. When the mounting bracket 3 returns to its unfolded state with the main spring 2, the mounting bracket 3 moves downward relative to the inner cover 1, away from the locking member 5. At this time, the locking member 5, guided by the structure of the mounting hole 14, rolls along the mounting hole 14 towards the mounting bracket 3 and retracts into the mounting hole 14, preventing contact with the horizontal flange 210 when the cover 100 and the container 200 move away from each other.

[0026] In this embodiment, the locking element 5 is a rigid ball. The locking ball with a rigid spherical structure in this embodiment effectively ensures that the locking element 5 is stably clamped between the mounting bracket 3 and the horizontal protrusion 210 of the container 200, and ensures a stable locking connection between the cover 100 and the container 200.

[0027] In this embodiment, the positioning mechanism 6 includes a rotating cover 42 and a mounting bracket 3, which are respectively disposed on the top cover 4 and rotate relative to the top cover 4. Connecting protrusions 61 extend towards each other and hook or separate through rotation. When the alignment marks between the rotating cover 42 and the mounting bracket 3 or the top cover 4 are aligned, the positioning mechanism 6 can rotate and disengage. In this embodiment, the rotating cover 42 is mounted on the top cover 4 and can rotate relative to the top cover 4.

[0028] The principle and process of the lid 100 quickly closing the container 200 in this embodiment are as follows: This embodiment is provided with a cover 100 that is locked together and a container 200 with an opening; the opening of the container 200 is provided with a horizontal flange 210; the main spring 2, when subjected to a downward external force, retracts until the mounting bracket 3 moves upward relative to the inner cover 1 to the locking position between the cover 100 and the container 200, and the mounting bracket 3 pushes the locking member 5, which passes through the inner cover 1, to protrude from the lower end of the inner cover 1 and form an abutment with the horizontal flange 210; as the cover 100 and the container 200 reach the locking position, they are interlocked through relative rotation to keep the cover 100 locked. The container 200 is quickly closed; when it is necessary to open the lid 100, the positioning mechanism 6 is rotated to a position where the two are not connected, releasing the mutual restraint between the mounting bracket 3 and the top cover 4. At the same time, the main spring 2 extends from the contracted state, and the mounting bracket 3 moves down relative to the locking member 5 and the inner cover 1, separating the container 200 from the lid 100. In this embodiment, the opening and closing is quick, and the downward compression of the main spring 2, combined with the rotation positioning mechanism 6, positions the lid 100 and the container 200 in the locked position, effectively ensuring the lid is closed while facilitating operation.

[0029] This embodiment can also achieve fast unlocking, and the specific unlocking process is as follows: This embodiment utilizes a cover 100 consisting of an inner cover 1, a main spring 2, a mounting bracket 3, and a top cover 4 arranged coaxially from bottom to top, along with a horizontal flange 210 at the opening of the container 200. When the cover 100 is not closed at the opening of the container 200 and both the spring 72 and the main spring 2 in the spring-loaded assembly 7 are in their naturally extended state, the locking member 5 driven or actuated by the mounting bracket 3 is in a position suitable for axially engaging with the horizontal flange 210. When the cover 100 is closed at the opening of the container 200, the recessed portion 11 of the inner cover 1 extends into the opening of the container 200, and the support portion 12 of the inner cover 1 corresponds to the horizontal flange 210. At this time, the mounting base 73 provides support. As the horizontal flange 210 and mounting bracket 3 exert downward force, the main spring 2 is compressed. When the downward force is removed, the main spring 2 returns to its natural length. The locking member 5 moves upward with the mounting bracket 3 and abuts against the horizontal flange 210 from below, locking the cover 100 to the container 200 along the circumference. Then, the top cover 4 is pressed down further, the spring 72 retracts, the positioning mechanism 6 rotates, and the mounting bracket 3, inner cover 1, and horizontal flange 210 of the container 200 form a rigid mechanical contact in the axial direction of the container 200. The top cover 4 and the mounting bracket 3, and the mounting bracket 3 are locked and positioned in the axial direction between the locking member 5 and the horizontal flange 210, thereby ensuring a tight seal between the cover 100 and the container 200. When the lid needs to be opened, the rotation positioning mechanism 6 moves the top cover 4 and the mounting bracket 3 to an unconnected position, releasing the mutual restraint between the mounting bracket 3 and the top cover 4. The mounting base 73 can move between the top cover 4 and the mounting bracket 3 as the spring 72 extends, releasing the rigid contact. The mounting bracket 3 is pulled down, pushing the protrusion 32 away from the locking member 5. The locking member 5 moves away from the horizontal protrusion 210 along the mounting hole 14, releasing the contact between the locking member 5 and the horizontal protrusion 210. At the same time, the spring 72 of the spring assembly 7 acts on the horizontal protrusion through its own length change, causing the lid to detach from the horizontal protrusion and the lid to detach from the container, forming a bouncing effect, which is equivalent to opening the lid by rotating in the horizontal direction.

[0030] Based on the above process, the quick-opening device disclosed in this embodiment can achieve quick locking and quick opening, with a stable locking structure while ensuring a tight seal. This embodiment is suitable for use in drinking cups, thermos cups, teacups, coffee machines, juicers, and soy milk makers, etc.
