TECHNICAL FIELD

[0001] The present application belongs to the field of sealing device, and particularly relates to a sealing cover. BACKGROUND

[0002] The storage tank (box) is a household necessity in daily life, and has various specific structures, but generally comprises a sealing cover and a tank body (box body), and the sealing function is realized by the connection of the two. In order to realize the sealing function, the connection mode between the sealing cover and the tank body (for the convenience of description, the tank body is taken as an example for description below) in the prior art is mainly divided into direct connection and indirect connection, and the direct connection mode is widely used due to low production cost and simple structure.

[0003] The direct connection is generally realized by an upper cover body, a lower cover body and a third connecting piece (generally an elastic sealing piece), but the third connecting piece is limited by the assembly mode between the upper cover body and the lower cover body, which affects the efficiency of opening the sealing cover on the tank body by one hand, that is, the function of quickly opening or closing the sealing cover by one action cannot be realized, and the instant sealing performance during the opening and closing of the tank body by one hand cannot be met. SUMMARY

A control mechanism is movably connected to the upper part of the upper cover body, the control mechanism movably penetrates through the upper cover body and is movably connected with the lower cover body, and the upper cover body is driven to move away from the lower cover body by exerting force on the control mechanism by one hand. An elastic execution mechanism is arranged between the lower cover body and the upper cover body, the lower end of the elastic execution mechanism is press-bonded with the upper cover body, the upper end of the elastic execution mechanism is press-bonded with the lower cover body, and the elastic execution mechanism promotes the upper cover body to move close to the lower cover body in the process of elastic elongation.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] The present invention will now be described clearly, completely and in detail with reference to the accompanying drawings. Example

[0021] Combined with appendix Figures 1-9 A sealing cover includes an upper cover body 1, a lower cover body 2, and an elastic sealing element 3, wherein the elastic sealing element 3 simultaneously presses against the edge of the upper cover body 1 and the edge of the lower cover body 2. The upper part of the upper cover 1 is movably connected to the control mechanism 4. The control mechanism 4 moves through the upper cover 1 and is movably connected to the lower cover 2. By applying force to the control mechanism 4 with one hand, the upper cover 1 is moved away from the lower cover 2. An elastic actuator 5 is provided between the lower cover 2 and the upper cover 1. The lower end of the elastic actuator 5 is pressed against the upper cover 1, and the upper end of the elastic actuator 5 is pressed against the lower cover 2. During the elastic elongation process, the elastic actuator 5 causes the upper cover 1 to move closer to the lower cover 2.

[0022] The sealing cap of this invention can be used with open-type container equipment of different materials such as glass cups, thermos cups, and storage jars, making it highly adaptable and widely applicable.

[0023] In use, the elastic deformation of the elastic seal 3 achieves a tight fit with the tank body, specifically in the following two cases: 1) Hold the control mechanism 4 with one hand. During the movement of the control mechanism 4, gradually bring it against the lower cover 2, so that the upper cover 1 and the lower cover 2 move away from each other. Since the elastic seal 3 is pressed against the upper cover 1 and the lower cover 2, the elastic seal 3 will shrink inward, thereby releasing the tight fit between it and the inner wall of the tank, so as to remove the device from the tank. 2) Hold the control mechanism 4 with one hand again and place it back into the tank opening. Then, under the action of the elastic actuator 5, the upper cover 1 and the lower cover 2 move closer to each other, thereby causing the elastic seal 3 to expand outward. During the expansion process, it gradually contacts and presses against the inner wall surface of the tank opening, thus achieving the sealing function.

[0024] During this process, the control mechanism 4 and the flexible actuator 5 cooperate with each other to quickly and effortlessly remove the sealing cap from the tank, and achieve the function of quickly and conveniently controlling the sealing of the tank.

[0025] Combined with appendix Figures 2-4 The elastic actuator 5 includes a longitudinally arranged telescopic spring 5-1. A spring limiting groove 6 is recessed downward on the upper surface of the upper cover 1. The lower end of the telescopic spring 5-1 is pressed into the spring limiting groove 6. An arched stop bar 2-3 is fixedly connected to the upper part of the lower cover 2. The upper end of the telescopic spring 5-1 is pressed into the arched stop bar 2-3.

[0026] When the upper cover 1 moves away from the lower cover 2, the arched stop bar 2-3 compresses the telescopic spring 5-1; when the telescopic spring 5-1 recovers its deformation, it applies a downward force to the upper cover 1, which causes the upper cover 1 to gradually move closer to the lower cover 2.

[0027] The lower end of the telescopic spring 5-1 is fixed to the upper cover 1 by the spring limiting groove 6 to prevent significant lateral displacement. Specifically, when the sealing cover is removed from the can, the upper cover 2 and the lower cover 2 move away from each other, and the telescopic spring 5-1 is compressed; when the sealing cover is put back on the can, the telescopic spring 5-1 gradually returns to its original shape, thereby pushing the upper cover 1 and the lower cover 2 closer together.

[0028] Combined with appendix Figure 4 and 8 The control mechanism 4 includes two symmetrically distributed rotating flaps 4-1. One end of each rotating flap 4-1 extends downward and moves through the upper cover 1, and then is rotatably connected to the lower cover 2.

[0029] Under the action of opposing forces, the two rotating flaps 4-1 flip upward around the upper cover 1. During the rotation, the rotating flaps 4-1 apply a downward force to the lower cover 2. As the lower cover 2 moves downward, it pulls the elastic sealing element 3 that is pressed against it, causing it to contract inward. This allows the device to be easily removed from the tank opening, making the operation quick and convenient.

[0030] When the device needs to be reassembled at the tank opening, hold the two rotating flaps 4-1 and place them at the tank opening. After the hands are removed from the rotating flaps 4-1, the upper cover 1 and the lower cover 2 move closer to each other under the action of the telescopic spring 5-1 restoring its deformation, which causes the elastic sealing element 3 to expand outward, thereby quickly sealing the tank.

[0031] Combined with appendix Figure 5 and 6 As the rotating flap 4-1 passes through the upper cover 1, one end of it is rotatably engaged with the upper cover 1 via a rotating shaft 2-2 fixed to its side. A hook 2-4 is fixedly attached to the upper surface of the lower cover 2, and one end of the rotating flap 4-1 is movably engaged with the hook 2-4.

[0032] When a force is applied to the rotating flap 4-1 in a relative direction, the bottom part of one end of the rotating flap 4-1 acts as a fulcrum 9, and a downward force is generated on the lower cover 2 through the fulcrum 9, thereby causing the lower cover 2 to gradually move away from the upper cover 1.

[0033] The hooks 2-4 are designed to prevent the upper cover 1 from physically separating from the lower cover 2 when the upper cover 1 is held by hand.

[0034] Combined with appendix Figures 5-9 The lower part of the upper cover 1 is fixedly connected to several limiting guide rails 7, and the upper part of the lower cover 2 is fixedly connected to several mounting protruding strips 2-5. The mounting protruding strips 2-5 are movably engaged with the limiting guide rails 7.

[0035] The convex ribs 2-5 are assembled and locked together with the limiting guide rails 7 to prevent parallel movement when the upper cover 1 and the lower cover 2 move relative to each other, thus ensuring that there is no significant reduction in assembly accuracy during repeated control of this device.

[0036] Combined with appendix Figures 4-6 The upper cover 1 has an upper pressing edge 1-1 extending downward from the lower part, and the lower cover 2 has a lower pressing edge 2-1 extending upward from the upper part. The elastic seal 3 presses against both the upper pressing edge 1-1 and the lower pressing edge 2-1, and the outer periphery of the elastic seal 3 protrudes outward in a pointed cone shape.

[0037] The upper pressure joint 1-1 and the lower pressure joint 2-1 are designed to ensure a certain degree of overlap with the elastic seal 3, thereby ensuring continuous contact between the upper cover 1 and the lower cover 2 as they move closer or further apart.

[0038] Furthermore, in order to quickly achieve a tight fit between the elastic seal 3 and the tank body, the elastic deformation properties of the elastic seal 3 are fully utilized, especially the horizontal deformation. Specifically, after the elastic seal 3 deforms, the pointed cone-shaped part first contacts the inner wall of the tank and is squeezed (see attached diagram). Figure 3 and 4 This ensures a tight fit between the sealing cap and the tank body, thereby guaranteeing the tank's airtightness.

[0039] As an extension, in order to quickly achieve a seal between the cap and the tank, the number of cone-shaped protrusions can be changed, and the spacing between adjacent cone-shaped protrusions can be adjusted, thereby increasing the contact area with the tank and improving the seal.

[0040] Reference Appendix Figure 3 and 4 The cross-sections of the lower pressing edge 2-1 and the upper pressing edge 1-1 are both annular. The longitudinal section of the lower pressing edge 2-1 is bent at a right angle. The lower end of the elastic seal 3 is engaged at the bent position, and the upper end of the elastic seal 3 extends horizontally outward to a position close to the upper cover 1.

[0041] The bending structure and the horizontal outward extension of the upper end of the elastic seal 3 can further improve the pressing stability between the elastic seal 3 and the upper pressing edge 1-1 and the lower pressing edge 2-1, thereby further ensuring the connection stability between the upper cover 1 and the lower cover 2, and thus optimizing the action execution efficiency of the device.

[0042] Under normal conditions, the elastic seal 3 simultaneously presses against the upper cover 1 and the lower cover 2, specifically pressing against the upper pressing edge 1-1 and the lower pressing edge 2-1 respectively. When the upper cover 1 and the lower cover 2 move away from each other, the elastic seal 3 is subjected to longitudinal tension, causing its conical portion to contract inward, thereby enabling the seal to be easily removed from the tank.

[0043] Then, when the sealing cap is placed on the tank again, the upper cap 1 and the lower cap 2 approach each other, causing the elastic sealing element 3 to gradually recover its deformation and press against the inner wall of the tank, thus achieving the sealing function.

[0044] Reference Appendix Figures 1-9 The upper pressing edge 1-1 is distributed at the edge of the upper cover 1, and the lower pressing edge 2-1 is distributed at the edge of the lower cover 2; the elastic sealing element 3 is a ring structure with a V-shaped longitudinal section.

[0045] By positioning both the upper pressure edge 1-1 and the lower pressure edge 2-1 close to the edge of the upper cover 1 or the lower cover 2, the elastic seal 3 can quickly conform to the inner wall of the tank when the sealing cover is placed on it, improving installation efficiency. The V-shaped cross-section design facilitates the pressing connection with the upper cover 1 and the lower cover 2, and increases the horizontal deformation of the elastic seal 3 from the side, thus adapting to tanks with different tolerance ranges.

[0046] Reference Appendix Figure 4 The lower part of the upper cover 1 has an annular limiting part 1-2 extending downward, and the annular limiting part 1-2 and the upper pressing edge 1-1 form a channel 8, through which the elastic sealing member 3 passes.

[0047] Channel 8 forms a secondary limit on the elastic seal 3, thereby further improving the overall stability of the device and the coordination between various components inside the device.

[0048] The spring limiting groove 6 is located in the middle of the upper cover 1, which is a funnel-shaped structure that gradually concaves from the edge to the center.

[0049] The funnel-shaped structure ensures the ease of operation of the control mechanism 4 and improves the overall compactness of the structure.

[0050] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
