[0012] The beneficial effects of the present invention are as follows: a can cap is provided, wherein a sealable space is formed between the annular cylinder and the cover plate, the open mouth of the can is placed in the space, and the can is gripped by the left sealing component and the right sealing component, so that the can is maintained in a sealed state. Specifically, the sliding plate slides on the cover plate, and while the sliding plate slides, it drives the first rack located in the storage groove to move, so that the first gear rotates, and when the first gear rotates, it drives the second gear to rotate, and when the second gear rotates, it drives the second rack to move up and down, so that the clamping block moves up and down, and when the sliding plate moves to the end of the stroke, the transmission block moves downward and compresses the spring through the transmission of the gear and the rack, and the clamping block moves downward to the bottom of the guide block, and when the sliding plate moves to the beginning of the stroke, the transmission block moves upward through the transmission of the gear and the rack. The spring returns to its original state, and when the clamping block moves upward, the clamping block deflects toward the middle of the annular cylinder under the guidance of the guide block and the connection of the torsion spring. When the user uses it, the sliding plate is first moved to the end of the stroke under the action of external force, and then the can is placed in the space formed by the annular cylinder and the cover plate. At this time, the external force on the sliding plate is removed or a force in the opposite direction of the sliding plate is applied. The spring returns to its original state and pushes the transmission block to rise. The clamping block clamps the top edge of the can and applies an upward force to press the can against the cover plate, so that the cover plate seals the top of the can. Therefore, the present invention is very convenient to use. When in use, two fingers can be used to slide the sliding plates on the left sealing assembly and the right sealing assembly toward the middle of the cover plate, and the can is placed in the annular cylinder. The can can be clamped by releasing the hand to complete the sealing. It has strong versatility. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] As can be seen from the above, the present invention provides a can cap, wherein a sealable space is formed between the annular cylinder 2 and the cover plate 1, the open mouth of the can is placed in the space, and the can is gripped by the left sealing component and the right sealing component, so that the can is maintained in a sealed state. Specifically, the sliding plate 3 slides on the cover plate 1, and while the sliding plate 3 slides, it drives the first rack 5 located in the storage groove 4 to move, so that the first gear 6 rotates, and when the first gear 6 rotates, it drives the second gear 7 to rotate, and when the second gear 7 rotates, it drives the second rack 8 to move up and down, so that the clamping block 11 moves up and down. When the sliding plate 3 moves to the end of the stroke, the transmission block 9 moves downward and compresses the spring 10 through the transmission of the gear and the rack, and the clamping block 11 moves downward to the bottom of the guide block 13. When the sliding plate 3 moves to the beginning of the stroke, the transmission block 9 moves upward through the transmission of the gear and the rack, and the spring 10 returns to its original state. When the clamping block 11 moves upward, it moves on the guide block 1 When the can is in the annular cylinder 2, the can is put into the annular cylinder 2, and the can is put into the space formed by the annular cylinder 2 and the cover plate 1. At this time, the external force on the sliding plate 3 is removed or a force in the opposite direction of the sliding plate 3 is applied. The spring 10 returns to its original state and pushes the transmission block 9 to rise. The clamping block 11 clamps the top edge of the can and applies an upward force to press the can against the cover plate 1, so that the cover plate 1 seals the top of the can. Therefore, the present invention is very convenient to use. When in use, the sliding plates 3 on the left and right sealing components can be slid and brought closer to the middle of the cover plate 1 with two fingers, and the can is put into the annular cylinder 2. The can can be clamped by releasing the hand to complete the sealing. It has strong versatility. Preferably, the first gear 6 and the second gear 7 can be respectively positioned in the receiving groove 4 through a rod passing through the center thereof, and the gears and the rod are connected to each other through bearings.

[0020] As a further preferred embodiment, an annular sealing gasket 14 is provided on the bottom surface of the cover plate 1, and the outer diameter of the annular sealing gasket 14 is the same as the inner diameter of the annular cylinder 2. The annular sealing gasket can strengthen the sealing performance of the top edge of the can and improve the sealing effect.

[0021] As a further preferred embodiment, the annular sealing gasket 14 is detachably connected to the cover plate 1, and the annular sealing gasket 14 can be removed for easy replacement and cleaning.

[0022] As a further preferred embodiment, the annular sealing gasket 14 is made of silicone material, which can further improve the sealing performance between the cover plate 1 and the top edge of the can.

[0023] Further as a preferred embodiment, the clamping block 11 is a triangular prism structure, and the side of the clamping block 11 away from the annular cylinder 2 is an inclined surface, which is inclined from bottom to top in the direction close to the central axis of the annular cylinder 2. When the clamping block 11 moves upward, it passes through the inclined surface of the guide block 13, climbs up the inclined surface under the guidance of the inclined surface, and the clamping block 11 rotates. At this time, the torsion spring 12 is twisted. When the clamping block 11 moves downward, it also returns to its original position under the guidance of the inclined surface. The clamping block 11 rotates, and at this time the torsion spring 12 returns to its original state. The whole process is very smooth and natural, reducing the sense of jamming during use.

[0024] Further as a preferred embodiment, the side of the clamping block 11 away from the transmission block 9 is inclined from top to bottom in the direction close to the transmission block 9. Since the outer diameter of the outer wall of the top of the can gradually decreases from bottom to top, the shape design of the clamping block 11 can better adapt to the surface of the can and enhance the grip on the can.

[0025] As a further preferred embodiment, a magnetic patch 15 is provided on the top surface of the cover plate 1, and the entire bottle cap can be adsorbed on a metal surface, such as a refrigerator, through the magnetic patch 15, so that the use functions are more diversified.

[0026] Further as a preferred embodiment, the top surface of the sliding plate 3 is evenly provided with a plurality of stripes along the radial direction of the annular cylinder 2, and the stripes are extended along the circumferential direction of the annular cylinder 2. The stripes increase the friction between the hand and the sliding plate 3 when the hand applies force to the sliding plate 3, facilitate the force, and further improve the user experience.

[0027] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
