DETAILED DESCRIPTION

[0049] The present invention is further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0050] Embodiment 1:

[0051] like Figure 1 , Figure 2As shown, in this embodiment, a sealing cover body comprises an outer cover 1, a bottom plate 2 arranged below the outer cover 1 and a sealing ring 3, the outer cover 1 comprises a cover plate 11, a cover plate through hole 12 arranged on the cover plate 11, a cover plate outer ring 13 arranged on one side of the cover plate 11, and a cover plate inner ring 14 connected to the cover plate through hole 12, the cross-sectional profile of the cover plate inner ring 14 is the same as the cover plate through hole 12, the cover plate inner ring 14 and the cover plate outer ring 13 are located on the same side of the cover plate 11, an inner ring bottom plate 15 is arranged at one end of the cover plate inner ring 14 away from the cover plate 11, a plurality of connecting columns 21 passing through the inner ring bottom plate 15 are arranged on the bottom plate 2, the sealing ring 3 is sleeved on the bottom plate 2, and an outer ring step 131 is arranged on the end surface of the cover plate outer ring 13 away from the cover plate 11, and the outer surface of the outer ring step 131 is inwardly reduced relative to the outer surface of the cover plate outer ring 13.

[0052] When in use, the outer cover 1 is placed on the opening of the container, and the bottom plate 2, the sealing ring 3 and the outer ring step 131 extend into the opening.

[0053] When the container needs to be sealed, the connection column 21 is controlled to move upward, and the connection column 21 can be used to drive the bottom plate 2 to move upward, and the bottom plate 2 drives the sealing ring 3 to move upward, and push the sealing ring into the gap between the outer ring step 131 and the container. By controlling the thickness of the gap to be smaller than the thickness of the sealing ring 3, the gap can be squeezed on the sealing ring 3 to enhance the sealing effect, and the compressed sealing ring 3 applies thrust to both sides, which can clamp the container and the outer ring step 131, thereby realizing the function of sealing the container.

[0054] When the container needs to be opened, the connecting column 21 is controlled to move downward. Under the action of external force, the connecting column 21 drives the bottom plate 2 to move downward, and the bottom plate 2 drives the sealing ring 3 to move downward, so that the sealing ring 3 is separated from the gap and the outer cover 1 is loosened, so that the outer cover 1 can be opened.

[0055] In this embodiment, the control of the connecting column 21 can be achieved through a button and a connecting rod mechanism that is transmission-connected to the button. The button is used to provide external force, and the connecting rod mechanism is used to change the direction of the force. When the button is pressed downward, the direction of the force is changed by the connecting rod and transmitted to the connecting column 21, so that the connecting column is pulled upward, making the control of the connecting column 21 more convenient.

[0056] The bottom plate 2 and the sealing ring 3 can isolate the inner space of the container from the upper space of the bottom plate 2, so that the pressing operation is performed outside the container to avoid contamination inside the container during pressing. The inner ring bottom plate 15 and the inner ring of the cover plate 14 can also form a preliminary isolation.

[0057] Embodiment 2:

[0058] like Figure 1 , Figure 3As shown, based on the above embodiment, in this embodiment, the portion of the connecting column 21 that exceeds the inner ring bottom plate 15 is hinged with an obtuse-angled transmission rod 22, and the outer corner of the transmission rod 22 is in contact with the inner ring bottom plate 15.

[0059] The connecting rod adopts an obtuse-angled transmission rod 22, which can be used as a lever, so that the outer corner of the transmission rod 22 contacts the inner ring bottom plate 15 to form a fulcrum. When pressure is applied to the free end of the transmission rod 22 through the button, the transmission rod 22 rotates around the fulcrum, the free end of the transmission rod 22 rotates downward, and the end of the transmission rod 22 hinged to the connecting column 21 rotates upward and drives the connecting column 21 to move upward, thereby achieving the effect of changing the direction of the force.

[0060] When the transmission rod 22 rotates, the fulcrum slides adaptively on the inner ring bottom plate 15, so as to adjust the distance between the fulcrum and the connecting column 21 to avoid interference.

[0061] Embodiment 3:

[0062] like Figure 3 As shown, on the basis of the above embodiment, in this embodiment, the connecting column 21 is provided with an open slot 211, the highest point of the open slot 211 is higher than the highest point of the opening of the open slot 211, and the transmission rod 22 is hinged to the open slot 211. The open slot 211 is provided to facilitate the connection between the transmission rod 22 and the connecting column 21, and the highest point of the open slot 211 is higher than the highest point of the opening of the open slot 211, so that the transmission rod 22 can be prevented from falling off from the open slot 211.

[0063] In this embodiment, the connecting posts 21 are located on the same circular ring, and the openings of the opening slots 211 face the same rotation direction, so that the free ends of the transmission rods 22 can point to the same rotation direction, and the arrangement of the transmission rods 22 can avoid interference between the transmission rods 22.

[0064] Embodiment 4:

[0065] like Figure 3 As shown, based on the above embodiment, in this embodiment, a spring 4 is provided between the inner ring bottom plate 15 and the bottom plate 2 .

[0066] After the external force applied to the connecting column 21 to move upward, the connecting column 21 drives the bottom plate 2 to move upward and compresses the spring 4. When the external force applied to the connecting column 21 is removed, the spring 4 returns to its original state and pushes the bottom plate 2 to move downward. In this way, the function of opening the sealing cover after the external force is removed can be realized.

[0067] In this embodiment, a spring limiting protrusion 151 is provided on the inner ring bottom plate 15, and the spring 4 is sleeved on the outside of the spring limiting protrusion 151. The spring limiting protrusion 151 can limit the spring 4 to prevent the spring 4 from moving randomly and affecting the use effect.

[0068] Embodiment 5:

[0069] On the basis of the above embodiment, in this embodiment, one end of the sealing ring 3 connected to the bottom plate 2 is provided with an annular connecting portion 31, and the bottom plate 2 is provided with a sealing ring connecting groove 23 connected to the connecting portion 31. The connection strength of the sealing ring 3 can be improved by the matching installation of the sealing ring connecting groove 23 and the connecting portion 31. In addition, the sealing ring 3 can be installed outside the sealing cover, which is convenient for cleaning or replacing the sealing ring 3.

[0070] Embodiment 6:

[0071] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a push-type timing sealing cover comprises a sealing cover body and a control structure, wherein the control structure comprises a pressure plate 5, a direction-changing plate 6 and a direction-changing column 7;

[0072] The pressure plate 5 is slidably disposed in the inner ring 14 of the cover plate, and the direction-changing plate 6 is rotatably disposed below the pressure plate 5, and the pressure plate 5 is in contact with the connecting column 21;

[0073] The steering disc 6 is provided with a through hole 61, and a plurality of steering teeth 62 are provided on the inner surface of the through hole 61;

[0074] The said direction-changing column 7 is cylindrical, and is arranged on the inner ring bottom plate 15 and is located in the through hole 61. A plurality of driving blocks are arranged on the outer circumferential surface of the direction-changing column 7, which can drive the direction-changing teeth 62 to rotate through the wedge surface and move in the vertical direction at the same time.

[0075] The pressing plate 5 is provided with a timer.

[0076] The pressure plate 5 is used as a button. By pressing the pressure plate 5, the transmission rod 22 can be driven to move, and then the transmission rod 22 drives the connecting column 21 to move. In the process of pressing the pressure plate 5 downward, the pressure plate 5 drives the change plate 6 to move downward. When the pressure on the pressure plate 5 is removed, the spring 4 pushes the bottom plate 2 to move downward under the action of the spring 4, and the bottom plate 2 drives the connecting column 21 to move downward. The connecting column 21 drives the transmission rod 22 to rotate around the fulcrum, and the free end of the transmission rod 22 drives the pressure plate 5 to move upward, and the pressure plate 5 drives the change plate 6 to move upward. Since the change plate 7 is provided with a wedge surface, the cooperation between the wedge surface and the change tooth 62 can control the limit position of the free movement of the change plate 6, thereby controlling the limit position of the movement of the pressure plate 5. In this way, the shape and position of the wedge surface are designed according to the needs, and the pressure plate 5 can be controlled to realize different functions such as opening the sealing cover and closing the sealing cover.

[0077] The timer can be used to record the time the item is stored in the container or the remaining shelf life, so as to manage the expiration date of the item.

[0078] Embodiment 7:

[0079] like Figure 6 As shown, on the basis of the above embodiment, in this embodiment, the driving block includes a plurality of upper adjustment blocks 71 arranged on the outer circumferential surface of the direction-changing column 7 and a lower adjustment block 72 located below the upper adjustment block 71, and a channel 73 through which the direction-changing tooth 62 can pass is formed between two adjacent upper adjustment blocks 71, and a V-shaped groove 74 with an opening facing downward is provided on the lower surface of the upper adjustment block 71, and a plurality of W-shaped grooves 75 corresponding to the V-shaped groove 74 are provided on the upper surface of the lower adjustment block 72. Along the same rotation direction, the V-shaped groove 74 includes an A surface 741 and a B surface 742 arranged in sequence from front to back, and the W-shaped groove 75 includes a C surface 751, a D surface 752, an E surface 753, and an F surface 754, wherein the C surface 751 is located below the channel 73, the D surface 752 is located below the A surface 741, and the E surface 753 is located below the B surface 742.

[0080] The deflection column 7 can be mounted on the inner ring bottom plate 15 by means of screws.

[0081] like Figure 7 As shown, assuming that the initial state of the sealing cover is open, after the sealing cover is installed on the container, the spring 4 is in a natural state, the distance between the sealing ring 3 and the inner ring bottom plate 15 is the largest, and the pressure plate 5 is in the highest position relative to the container opening.

[0082] The pressure plate 5 is pressed downward, and the pressure plate 5 drives the steering disc 6 to move downward. The steering tooth 62 in the steering disc 6 moves downward through the channel 73 and finally contacts the C-surface 751. The pressure plate 5 continues to move downward. Since the C-surface 751 is a downward inclined surface, the steering tooth 62 continues to move downward along the C-surface 751 through contact with the C-surface 751, and drives the steering disc 6 to rotate.

[0083] like Figure 8 As shown, when the pressure plate 5 moves to the lowest position, the sealing ring 3 rises to the highest position and enters into the gap between the container and the outer ring step 131 , and the direction-changing tooth 62 also moves to the lowest point of the C surface 751 .

[0084] like Fig. 9 As shown, the pressure plate 5 is released, and under the action of the spring 4, the bottom plate 2 and the sealing ring 3 are pushed downward, the pressure plate 5 and the steering disc 6 are pushed upward, and the steering tooth 62 moves upward following the steering disc 6 until it contacts the A surface 741. Since the A surface 741 is an upwardly inclined inclined surface, the steering tooth 62 continues to move along the direction of the A surface 741 until it moves to the highest point of the A surface 741 and cannot move further. At this time, the pressure plate 5 and the steering disc 6 cannot move, and the sealing ring 3 has not escaped from the gap between the container and the outer ring step 131, so that the sealing ring 3 can keep squeezing the container and the outer ring step 131, thereby realizing the state in which the container is sealed and closed.

[0085] Continue to press the pressure plate 5, and the direction-changing tooth 62 moves downward with the direction-changing plate 6 until it contacts the E surface 753. The E surface 753 is a downwardly inclined slope. The direction-changing tooth 62 moves downward along the E surface 753 and drives the direction-changing plate 6 to rotate until it moves to the lowest point of the E surface 753, which is the highest point of the upward movement of the bottom plate 2 and the sealing ring 3.

[0086] Release the pressure plate 5. Under the action of the spring 4, the bottom plate 2 and the sealing ring 3 are pushed downward, the pressure plate 5 and the steering plate 6 are pushed upward, and the steering tooth 62 enters the channel 73 through the space above the F surface 754 and continues to move upward until the pressure plate 5 moves upward to the limit position, and the bottom plate 2 and the sealing ring 3 move downward to the limit position. At this time, the sealing ring 3 is out of the gap and the sealing cover is opened.

[0087] In this way, the function of opening or closing the sealing cover can be realized by pressing the pressure plate 5 as a button once, which has the advantages of being convenient and quick to use.

[0088] Embodiment 8:

[0089] On the basis of the above-mentioned embodiment, in this embodiment, the front of the C surface 751 is connected to a G surface 755 which is higher than the C surface 751 and vertical, and the G surface 755 is coplanar with the front side surface of the channel 73 .

[0090] The G surface 755 can guide and limit the movement of the direction-changing tooth 62 , thereby preventing the direction-changing tooth 62 from entering above the F surface 754 .

[0091] In this embodiment, the rear of the F surface 754 is connected to an H surface 756 which is higher than the F surface 754, and the H surface 756 is inclined upward. The rear of the B surface 742 is connected to an I surface 743 which is parallel to the H surface 756. The H surface 756 and the I surface 743 form an oblique channel 76 which is connected to the channel 73 and through which the changing tooth 62 can pass.

[0092] The oblique channel 76 can guide and limit the direction-changing tooth 62 , and prevent the direction-changing tooth 62 from moving to the wrong position and affecting normal use during the process of opening the sealing cover.

[0093] Embodiment 9:

[0094] like Figure 5 As shown, on the basis of the above embodiments, in this embodiment, the direction-changing tooth 62 is in the shape of a triangular prism, and the longest side of the direction-changing tooth 62 is vertically arranged. The side surface at the bottom of the direction-changing tooth 62, the C surface 751 and the E surface 753 have the same inclination angle relative to the horizontal plane, and the side surface at the top of the direction-changing tooth 62 and the A surface 741 have the same inclination angle relative to the horizontal plane.

[0095] During the movement of the direction-changing tooth 62, the contact between the direction-changing tooth 62 and the upper adjustment block 71 or the contact between the direction-changing tooth 62 and the lower adjustment block 72 is surface contact, which prevents the direction-changing tooth 62 from scratching the upper adjustment block 71 or the lower adjustment block 72, and avoids unnecessary protrusions on the direction-changing tooth 62 and causing interference.

[0096] Embodiment 10:

[0097] like Figure 6 As shown, based on the above embodiment, in this embodiment, the upper surface of the upper adjustment block 71 is an arc shape that bulges upward.
