[0002] The utility model patent CN202322886581.0 discloses a water cup with a quick-open lid, comprising a cup body and a cup lid covered on the cup body, the cup lid comprising a lid body and a rotating lid, one end of the rotating lid being hinged to one end of the lid body, a drinking port being provided on the lid body, a control block being provided in the lid body, a clamping block being extended and formed at one end of the control block, a clamping portion being clamped with the clamping block being provided at the other end of the rotating lid, a sliding member for driving the control block being further provided on the lid body, a sliding inclined surface being provided on the inner side of the sliding member, a control inclined surface being matched with the sliding inclined surface at the other end of the control block, the sliding member being driven to move downward, the sliding inclined surface abutting against the control inclined surface, the control block moving inwardly releases the clamping state between the clamping block and the clamping portion, At this time, the rotating cover can rotate relative to the cover body; when the user wants to drink water, he only needs to slide the sliding member downward. At this time, the sliding slope on the inner side of the sliding member abuts against the control slope on the control block. The user continues to slide the sliding member downward, and the sliding member drives the control block to move inward. The control block drives the clamping block to move inward together to disengage the clamping part and release the clamping state with the rotating cover. At this time, the rotating cover can rotate relative to the cover body, and the cup cover can be opened. The user can drink the water in the cup through the drinking port on the cover body. Compared with most cups on the market, the cup body and the cup cover are mostly connected by threads. When opening, both hands are required to work together, which is inconvenient. The patent can open the rotating cover on the cover body by sliding the sliding member downward. The operation is simple, fast and convenient, which provides convenience for users. In the prior art, since there is a hinged result between the cover body and the container, it is not conducive to quick and bounce opening of the cover. Summary of the invention

[0013] Another object of the present invention is to provide a quick lid opening method, which utilizes a pop-up assembly to drive the relative position change between the mounting frame and the horizontal ridge of the container opening position to synchronize the main spring from a contracted state to a naturally extended state, effectively driving the lid body to separate from the horizontal ridge of the container, thereby achieving quick pop-up lid opening.

[0014] In order to solve this technical problem, the technical solution of the present invention is: a method for using the quick cover opening device proposed by the present invention, comprising the following steps: S1.

[0015] By adopting the above technical solution, the beneficial effects of the present invention are: The present invention utilizes a cover body composed of an inner cover, a main spring, a mounting frame and a top cover which are coaxially arranged from bottom to top to cover the container opening, and a horizontal convex edge of the container opening. When the cover body is not covered at the opening position of the container and the pop-up spring and the main spring in the pop-up assembly are in a naturally extended state, in this state, the locking member driven or driven by the mounting frame is in a position suitable for forming an axial hooking with the horizontal convex edge; when the cover body is covered at the opening position of the container, the lower recess of the inner cover extends into the opening position of the container, and the supporting portion of the inner cover corresponds to the horizontal convex edge. At this time, the mounting seat is supported on the water The flat convex edge and the mounting frame compress the main spring with the downward force. When the downward force is removed, the main spring returns to its natural length, and the locking member moves upward with the mounting frame to press against the horizontal convex edge from below along the circumference to lock the cover body in the container through the horizontal convex edge; then the top cover is further pressed down to retract the spring, and the positioning mechanism is rotated. The mounting frame, the inner cover, and the horizontal convex edge of the container, which are adjacent to each other in the axial direction of the container, successively form rigid mechanical contact, and the top cover and the mounting frame, and the mounting frame are locked and positioned in the axial direction between the locking member and the horizontal convex edge, thereby ensuring that the cover body and the container are tightly covered; When it is necessary to open the cover, the positioning mechanism is rotated to a position where the top cover and the mounting bracket are not hooked, the mutual limitation between the mounting bracket and the top cover is released, and the pop-up spring of the pop-up assembly and the mounting seat can move between the top cover and the mounting bracket as the pop-up spring is extended, the rigid contact is released, and the mounting bracket is pulled down, the locking piece can move or deform away from the horizontal convex edge, and the locking piece moves away from the horizontal convex edge, releasing the interference between the locking piece and the horizontal convex edge; at the same time, the pop-up spring of the pop-up assembly acts on the horizontal convex edge through its own length change, so that the cover body is separated from the horizontal convex edge, and the cover body is separated from the container, forming a bouncing effect, which is equivalent to realizing the opening of the cover by a horizontal rotation action.

DETAILED DESCRIPTION

[0018] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0019] Example 1 This embodiment discloses a fast switching device, such as Figures 1 to 12 As shown, a cover body 100 and a container 200 with an opening are arranged to cover and lock each other; a horizontal convex edge 210 is arranged at the opening position of the container 200; the cover body 100 includes, from bottom to top, an inner cover 1 coaxially arranged to cover the opening of the container 200, a main spring 2, a mounting frame 3 and a top cover 4; at least two locking members 5 are evenly arranged along the circumference of the corresponding horizontal convex edge 210 between the inner cover 1 and the mounting frame 3; the main spring 2 is contracted by the downward external force until the mounting frame 3 moves downward relative to the inner cover 1 to the cover body 10 0 and the container 200 to the bottom of the locking position to form a support with the mounting seat 73 and the horizontal convex edge 210, the mounting frame 3 moves to the initial position relative to the inner cover 1 as the main spring 2 recovers to the initial length, and pushes the locking piece 5 that passes through the inner cover 1 to protrude from the inner cover 1 and form a conflict with the lower end of the horizontal convex edge 210 through the pushing protrusion 32; it also includes a positioning mechanism 6 arranged between the top cover 4 and the mounting frame 3, which is connected to each other through relative rotation as the cover body 100 and the container 200 reach the locking position to keep the mounting frame 3 in the locking position.

[0020] This embodiment also includes a pop-up component 7, which includes a positioning frame 71 coaxially arranged with the mounting frame 3 and a pop-up spring 72; a plurality of mounting seats 73 for mounting the positioning pop-up spring 72 are sequentially arranged along the circumferential direction of the positioning frame 71, and the mounting seat 73 corresponds to the horizontal protrusion 210 of the container 200; the pop-up spring 72 is located between the top cover 4 and the mounting seat 73.

[0021] In this embodiment, the top cover 4 is provided with a positioning sleeve 41 toward the mounting seat 73 , and the mounting seat 73 is provided with a positioning column 731 nested with the positioning sleeve 41 . The pop-up spring 72 is installed in the mounting seat 73 through the positioning sleeve 41 .

[0022] In this embodiment, the mounting seat 73 is provided with a column 732 on one side facing the inner cover 1, passing through the inner cover 1 and corresponding to the horizontal convex edge 210 of the container 200. The pop-up assembly 7 in this embodiment interacts with the horizontal convex edge 210 through the column 732, effectively ensuring the pop-up effect generated by the pop-up spring 72 restoring the deformation. The cover body 100 uses the column 732 to ensure that the restoring force of the pop-up spring 72 effectively promotes the separation between the cover body 100 and the container 200.

[0023] In this embodiment, the mounting frame 3 is provided with a push protrusion 32 corresponding to the locking member 5 on one side thereof facing the locking member 5. In this embodiment, the push protrusion 32 is located below the locking member 5 when the cover 100 and the container 200 are not locked and the main spring 2 is in a naturally extended state. When the main spring 2 is shortened by external pressure, the mounting frame 3 moves downward relative to the inner cover 1 fixed to the opening of the container 200, and the push protrusion 32 protruding from the inner wall of the mounting frame 3 moves from below the locking member 5 into the installation gap between the inner wall of the mounting frame 3 and the inner cover 1 as the main spring 2 shortens, thereby ensuring that the mounting frame 3 and the locking member 5 are reliably pushed and contacted. On the other hand, when the main spring 2 is in a naturally extended state, the width of the gap between the mounting frame 3 and the inner cover 1 can ensure that the locking member 5 is basically located in the installation hole 14 passing through the inner cover 1, thereby avoiding the relative movement between the cover 100 and the horizontal convex edge 210 and obstruction of the horizontal convex edge 210. When the mounting frame 3, the top cover 4 and the horizontal flange 210 of the container 200 are in the locked position and the positioning mechanism 6 is in cooperation, the locking member 5 arranged along the circumference of the horizontal flange 210 forms an axial hook connection with the horizontal flange 210 at the position of the mounting frame 3, thereby forming an axial positioning of the cover body 100 relative to the horizontal flange 210 of the container 200, thereby achieving sealing and locking of the cover body 100 and the container 200.

[0024] The inner cover 1 in this embodiment includes a lower concave portion 11 extending into the container 200 to cover the opening, a support portion 12 for contacting the opening position of the container 200, and a stopper 13 extending from the support portion 12 toward the lower end of the mounting bracket 3. The inner cover 1 in this embodiment has a continuous structure, the lower concave portion 11 and the support portion 12 effectively cover the opening of the container 200, and the stopper 13 continuously extending from the inner cover 1 is used to open a portion penetrating the inner cover 1 for the mounting bracket 3 to be hooked and positioned with the horizontal convex edge 210 of the container 200, thereby locking the cover body 100 at the opening of the container 200.

[0025] In this embodiment, the mounting frame 3 is fixed with a driving member 31 for applying downward pressure along the circumferential direction, and an anti-slip structure is provided on the surface of the driving member 31. In this embodiment, the driving member 31 is provided to facilitate contact with fingers and prevent slipping.

[0026] In this embodiment, the diameter of the mounting hole 14 facing the mounting frame 3 is D1, and the diameter of the mounting hole 14 facing the container 200 is D2, wherein D1 is larger than D2. In this embodiment, by providing the mounting hole 14 with different opening sizes at both ends, it is ensured that the locking member 5 is installed between the inner cover 1 and the side wall of the mounting frame 3. When the mounting frame 3 is compressed due to the external force of the main spring 2, the mounting frame 3 moves downward relative to the inner cover 1 and away from the locking member 5. At this time, the locking member 5 rolls along the mounting hole 14 toward the mounting frame 3 due to the structural guidance of the mounting hole 14, and retracts into the mounting hole 14, so as to avoid contact with the horizontal convex edge 210 when the cover body 100 and the container 200 move away from each other.

[0027] The locking member 5 in this embodiment is a rigid ball. The locking ball with a rigid spherical structure in this embodiment effectively ensures that the locking member 5 is stably clamped between the mounting frame 3 and the horizontal convex edge 210 of the container 200, and ensures a stable locking connection between the cover 100 and the container 200.

[0028] In this embodiment, the positioning mechanism 6 includes a rotating cover 42 respectively disposed on the top cover 4 and rotating relative to the top cover 4 and a connecting protrusion 61 extending toward each other from the mounting frame 3 and hooking or separating from each other through rotation. When the alignment marks between the rotating cover 42 and the mounting frame 3 or the top cover 4 are aligned, the positioning mechanism 6 can be rotated to disengage. In this embodiment, the rotating cover 42 is installed on the top cover 4 and can rotate relative to the top cover 4.

[0029] The principle and process of the cover body 100 of this embodiment quickly closing the container 200 are as follows: The present embodiment is provided with a cover body 100 and a container 200 with an opening that are locked to each other; a horizontal convex edge 210 is provided at the opening position of the container 200; the main spring 2 that loses the downward external force is unfolded until the mounting frame 3 moves up relative to the inner cover 1 to the locking position between the cover body 100 and the container 200, and the mounting frame 3 pushes the locking piece 5 that passes through the inner cover 1 to protrude from the inner cover 1 and form a conflict with the lower end of the horizontal convex edge 210; as the cover body 100 and the container 200 reach the locking position, the positioning mechanism 6 is rotated to form a mutual hook to maintain the rapid closing of the cover body 100 and the container 200; when it is necessary to open the cover body 100, the positioning mechanism 6 is rotated to a position where the two are not hooked, the mutual limit between the mounting frame 3 and the top cover 4 is released, the spring is restored to its initial length, a downward force is applied to the mounting frame 3, the main spring 2 is contracted, the lower end of the mounting frame 3 moves downward relative to the locking piece 5 and the inner cover 1, and the container 200 is separated from the cover body 100; the present embodiment is fast to open and close, effectively ensuring the closing while being convenient to operate.

[0030] Example 2 The main differences between this embodiment and embodiment 1 are shown in Figures 15 to 19 , arranged on a cover body 100 and a container 200 with an opening that are covered and locked with each other; a horizontal ridge 210 is provided at the opening position of the container 200; the cover body 100 includes, from bottom to top, an inner cover 1, a main spring 2, a mounting frame 3 and a top cover 4 that are coaxially arranged to cover the opening of the container 200; at least two locking members 5 are provided between the inner cover 1 and the mounting frame 3 corresponding to the horizontal ridge 210; the mounting frame 3 moves upward relative to the inner cover 1 under the action of the restoring elastic force of the main spring 2, and the locking member 5 passes through the inner cover 1 and forms an interference positioning with the lower end of the horizontal ridge 210 in a locked position.

[0031] In this embodiment, the inner cover 1 is provided with a vertical groove track 15, and a clearance hole 16 is provided in the middle of the groove track 15, which penetrates the inner cover 1 body 100 and connects to the horizontal convex edge 210; the locking member 5 passes through the clearance hole 16 of the inner cover 1 from the inner wall of the mounting frame 3 from bottom to top. During the movement of the locking member 5 along the groove track 15, it will bend and deform adaptively and move downward relative to the inner cover 1 to form a contraction, and contact the edge of the inner cover 1. When the mounting frame 3 loses the external downward pulling force, the restoring elastic force of the main spring 2 drives the mounting frame 3 to move upward, and the locking member 5 slides from the bottom of the clearance hole 16 to the clearance hole 16 along the groove track 15. The locking member 5 extends into the clearance hole 16 due to its own structure recovering to a straight state, and the upper end of the locking member 5 abuts against the horizontal convex edge 210 to lock the cover body 100 and the container 200. In order to further ensure that the mounting frame 3 and the inner cover 1 can slide relative to each other stably, the mounting frame 3 is provided with a guide protrusion 33 on one side of the locking member 5, and the inner cover 1 is provided with a positioning rail 17 which is nested with the guide protrusion 33. The inner cover 1 and the mounting frame 3 maintain relatively stable positioning in the circumferential direction and the radial direction during the relative up and down sliding process, thereby ensuring that the locking member 5 can achieve the contact and hooking of the locking member 5 with the horizontal protrusion 210 under the synchronous action of external force and the main spring 2 during the relative sliding of the inner cover 1 and the mounting frame 3 by utilizing the deformation of its own structure, thereby achieving locking and unlocking.

[0032] This embodiment also includes a pop-up component 7, which includes a positioning frame 71 coaxially arranged with the mounting frame 3, and a plurality of mounting seats 73 for mounting a positioning pop-up spring 72 are sequentially arranged along the circumferential direction of the positioning frame 71, and the mounting seat 73 corresponds to the horizontal protrusion 210 of the container 200; the pop-up spring 72 is located between the top cover 4 and the mounting seat 73.

[0033] In this embodiment, the top cover 4 is provided with a positioning sleeve 41 toward the mounting seat 73 , the mounting seat 73 is provided with a positioning column nested with the positioning sleeve 41 , and the pop-up spring 72 is installed in the mounting seat 73 through the positioning sleeve 41 .

[0034] In this embodiment, the mounting seat 73 is provided with a column 732 on the side facing the inner cover 1 and passing through the inner cover 1 and corresponding to the horizontal convex edge 210 of the container 200. The present invention utilizes the mounting seat 73 and the column 732 to cooperate with the horizontal convex edge 210 of the container 200 to ensure stable locking between the cover 100 and the container 200.

[0035] This embodiment also includes a positioning mechanism 6 disposed between the top cover 4 and the mounting frame 3. As the cover body 100 and the container 200 reach the locking position, they are connected to each other through relative rotation to keep the mounting frame 3 in the locking position.

[0036] In this embodiment, the inner cover 1 includes a lower concave portion 11 extending into the container 200 to cover the container opening, a support portion 12 for contacting the opening position of the container 200, and a limit portion 13 extending from the support portion 12 toward the lower end of the mounting bracket 3. The inner cover 1 of the present invention has a continuous structure, the lower concave portion 11 and the support portion 12 effectively cover the opening of the container 200, and further cooperate with the inner cover 1 to extend the extension portion continuously to open the inner cover 1 for the mounting bracket 3 and the container 200 horizontal convex edge 210 to form a snap-fit ​​positioning, thereby locking the cover body 100 at the opening of the container 200.

[0037] In this embodiment, the mounting frame 3 is fixed with a driving member 31 for applying downward pressure along the circumferential direction, and an anti-slip structure is provided on the surface of the driving member 31. The present invention facilitates contact with fingers and prevents slipping by providing the driving member 31.

[0038] In this embodiment, the positioning mechanism 6 includes connecting protrusions 61 respectively provided on the top cover 4 and the mounting frame 3 and extending toward each other to hook or separate from each other through rotation.

[0039] The specific working process of Example 1 and Example 2 is as follows: The present invention utilizes a cover body composed of an inner cover, a main spring, a mounting frame and a top cover which are coaxially arranged from bottom to top to cover the container opening, and a horizontal convex edge of the container opening. When the cover body is not covered at the opening position of the container and the pop-up spring and the main spring in the pop-up assembly are in a naturally extended state, in this state, the locking member driven or driven by the mounting frame is in a position suitable for forming an axial hooking with the horizontal convex edge; when the cover body is covered at the opening position of the container, the lower recess of the inner cover extends into the opening position of the container, and the supporting portion of the inner cover corresponds to the horizontal convex edge. At this time, the mounting seat is supported on the water The flat convex edge and the mounting frame compress the main spring with the downward force. When the downward force is removed, the main spring returns to its natural length, and the locking member moves upward with the mounting frame to press against the horizontal convex edge from below along the circumference to lock the cover body in the container through the horizontal convex edge; then the top cover is further pressed down to retract the spring, and the positioning mechanism is rotated. The mounting frame, the inner cover, and the horizontal convex edge of the container, which are adjacent to each other in the axial direction of the container, successively form rigid mechanical contact, and the top cover and the mounting frame, and the mounting frame are locked and positioned in the axial direction between the locking member and the horizontal convex edge, thereby ensuring that the cover body and the container are tightly covered; When it is necessary to open the cover, the positioning mechanism is rotated to a position where the top cover and the mounting bracket are not hooked, the mutual limitation between the mounting bracket and the top cover is released, and the pop-up spring of the pop-up assembly and the mounting seat can move between the top cover and the mounting bracket as the pop-up spring is extended, the rigid contact is released, and the mounting bracket is pulled down, the locking piece can move or deform away from the horizontal convex edge, and the locking piece moves away from the horizontal convex edge, releasing the interference between the locking piece and the horizontal convex edge; at the same time, the pop-up spring of the pop-up assembly acts on the horizontal convex edge through its own length change, so that the cover body is separated from the horizontal convex edge, and the cover body is separated from the container, forming a bouncing effect, which is equivalent to realizing the opening of the cover by a horizontal rotation action.

[0040] Combining Example 1 and Example 2, it can be seen that the present invention can achieve fast locking and fast opening, and the locking structure is stable while ensuring sealing. The present invention is suitable for use in drinking cups, thermos cups, tea cups, coffee machines, juice machines, and soybean milk machines.
