Similarly, words such as "one" or "a" do not indicate a quantity limitation, but indicate the existence of at least one.

[0029] In this embodiment, if Figure 1-8As shown, a sealing cover body that is easy to assemble is disclosed, including an upper cover 1, a lower cover 2 and a sealing ring 3. The upper cover 1 is provided with a handle 4 that can be opened and closed. The sealing ring 3 is arranged between the upper cover 1 and the lower cover 2. The lower cover 2 includes a bottom plate 5 and a connecting structure 6. A first side wall 51 in the shape of a circular ring is arranged on the upper surface of the bottom plate 5. A plurality of protrusions 52 are arranged on the inner side of the first side wall 51. The protrusions 52 are clamped with the upper side of the lower cover 2 to form a locking position 53. The locking positions 53 formed by each protrusion 52 and the lower cover 2 have the same inlet direction. The connecting structure 6 includes a snap ring 61 and two connecting arms 62 arranged at both ends of the snap ring 61 in the diameter direction. A plurality of locking portions 611 corresponding to the locking positions 53 are arranged on the outer side of the snap ring 61 along the circumferential side. The snap ring 61 can drive the locking portions 611 to enter the corresponding locking positions 53 by rotation to complete the connection with the bottom plate 5. The upper cover 1 is provided with two first channels 11, and the connecting arm 62 can pass through the first channels 11 to connect with the connecting end 41 of the handle 4. The upper and lower ends of the sealing ring 3 are respectively connected with the lower side of the upper cover 1 and the upper side of the lower cover 2. The connecting end 41 of the handle 4 can follow the opening and closing of the handle 4 to drive the bottom plate 5 to move up and down, and drive the sealing ring 3 to deform between the upper cover 1 and the lower cover 2. The sealing cover body adopts a protrusion provided on the inner side of the first side wall and a clamping ring arranged in the inner area of ​​the first side wall. The sealing cover body adopts a plurality of protrusions provided in the first side wall of the bottom plate and the upper surface of the bottom plate to form a plurality of locking positions, and the locking part on the outer side of the clamping ring is rotated into its corresponding locking position to fix the upper cover and the lower cover, so that when assembling the sealing cover body, it is only necessary to place the clamping ring connected to the upper cover on the lower cover, and then directly rotate the upper cover to rotate the clamping ring into the locking position. This avoids the need for the clamping ring in the prior art to be moved forwards or backwards or left and right to find the position of the locking position on the bottom plate after being placed on the bottom plate of the lower cover. The clamping ring is rotated and pushed into the locking position only after it roughly touches the corresponding locking position, and the installation process is cumbersome and time-consuming.

[0030] like Figure 3 As shown, in this embodiment, the protrusion 52 is a structure formed by protruding from the first side wall 51 toward the inner side wall, and there are four protrusions. The protrusion 52 includes a first protrusion 521 and a second protrusion 522. The first protrusion 521 is arranged along the inner side of the first side wall 51 parallel to the bottom plate 5. The two ends of the second protrusion 522 are respectively connected to the end of the first protrusion 521 and the upper side of the bottom plate 5. The second protrusion is arranged on the right side of the first protrusion, and the first protrusion is relatively perpendicular to the second protrusion. The first protrusion 521, the second protrusion 522 and the upper side of the bottom plate 5 surround to form a locking position 53. As shown in FIG. Figure 6As shown, the protrusion is used to limit the displacement of the locking part in the horizontal and vertical directions. The first protrusion limits the upward displacement of the locking part to ensure that the bottom plate can be driven upward when the connecting structure moves upward. The second protrusion limits the rightward displacement of the locking part to avoid the inaccurate position of the locking part entering the locking position, resulting in the bottom plate being unable to connect to the connecting structure. The protrusion and the locking part are used to connect the connecting structure to the bottom plate, and need to be set accordingly, and at least 2 pairs are provided. In other embodiments, the protrusion and the locking part can be set to other numbers, and the specific number is determined according to the size of the sealing cover body.

[0031] like Figure 7 As shown, in this embodiment, the first guide portion 531 and the second guide portion 532 are provided at one end of the locking position 53 away from the second protrusion 522, and the first guide portion 531, the second guide portion 532 and the upper side of the bottom plate 5 surround to form an entrance for the locking portion 611 to enter the locking position 53. The first guide portion 531 is arranged on the side of the first protrusion 521 close to the bottom plate 5, and the first guide portion 531 is set as an inclined surface or an arc surface gradually rising in the direction away from the bottom plate 5 from the lower bottom surface of the first protrusion 521 to the surface away from the first protrusion 521; the second guide portion 532 is arranged between the first protrusion 521 and the bottom plate 5, and the second guide portion 532 is set as a structure that gradually rises at the transition point of the first side wall 51 from the outer side of the locking position 53 to the inner side of the locking position 53, and the surface of the second guide portion 532 at the transition point from the outer side of the locking position 53 to the inner side of the locking position 53 is set as an inclined surface or an arc surface. The arc surface design of the first guide portion and the second guide portion facilitates the locking portion to enter the locking position, and prevents the locking portion from being blocked by the first protrusion at the left entrance of the locking position. Figure 6 As shown, the area from the second guide portion to the second protruding portion on the first side wall is higher than other areas. After the locking portion enters the locking position from the second guide portion, the extrusion force perpendicular to the first side wall inward is higher than the outer side of the locking portion, and the clamping ring can abut against the first side wall more tightly. In this embodiment, there are 4 protruding members, and the locking portion also has 4 corresponding protruding members. In other embodiments, the protruding members and the locking portion can also be set to other numbers, which are specifically set according to the size of the sealing cover body.

[0032] like Figure 3 , Figure 5 , Figure 7As shown, in this embodiment, an annular groove 63 is provided on the lower surface of the snap ring 61, and at least one protruding guide 54 is fixedly arranged on the upper surface of the bottom plate 5. The protruding guide 54 can move in the annular groove 63 to guide the locking portion 611 on the snap ring 61 to enter or exit the locking position 53. A stopper 631 protruding toward the groove top is provided at the first position of the bottom of the annular groove 63; after the locking portion 611 of the snap ring 61 is rotated to the corresponding locking position 53 along the first rotation direction, the rear end of the stopper 631 located at the first position in the first rotation direction abuts against the front end of the protruding guide 54. The setting of the stopper and the protruding guide can limit the locking portion from rotating out of the locking position after the locking portion enters the corresponding locking position, so as to ensure that the connection structure and the bottom plate can be stably connected in a natural state without external force. The first position is limited to the position of the right side of the protruding guide corresponding to the bottom of the annular groove when the locking portion is in the locking position. The first rotation direction is limited to the direction in which the locking portion is twisted when entering the locking position, that is, the clockwise direction when looking down at the lower cover. In another embodiment, the second protrusion can also be arranged on the left side of the first protrusion, and the corresponding locking portion needs to be rotated from the right side of the locking position into the locking position. The first position is limited to the position of the bottom of the annular groove corresponding to the left side of the protruding guide when the locking portion is in the locking position, and the first rotation direction is limited to the counterclockwise direction when looking down at the lower cover.

[0033] like Figure 3 and Figure 5 As shown, the raised guide is used to guide the locking portion 611 on the snap ring 61 to enter or exit the locking position 53, and at least one is required. In this embodiment, there are four raised guides 54, and four limiters 631 are also arranged accordingly. In other embodiments, the number of raised guides and limiters can be set according to the size of the sealing cover body. The greater the number of raised guides and limiters, the more stable the connection between the connecting structure and the bottom plate, and the greater the resistance encountered when the locking portion enters the locking position. The top of the limiter 631 and the raised guide 54 is set to an arc shape, which makes it easier for the locking portion to rotate in or out of the locking position.

[0034] like Figure 8 As shown, in this embodiment, the lower side of the upper cover 1 is provided with a second side wall 12 and a third side wall 13. The second side wall 12 is arranged in a circular ring on the lower surface of the upper cover 1, and when the handle 4 is closed, the second side wall 12 can be sleeved on the outside of the first side wall 51. The third side wall 13 is arranged on the outside of the second side wall 12, and is set in a square shape, with four sides tangent to the second side wall. A first connection area 31 for connecting the upper end of the sealing ring 3 is formed between the third side wall 13 and the lower edge of the upper cover 1. Figure 2As shown, the handle 4 includes a lifting portion 42 and two connecting ends 41 fixed to the rear of the lifting portion 42, and the connecting ends are arranged to extend downward perpendicularly to the rear end of the lifting portion. When the handle is closed, the distance between the upper cover and the lower cover is shortened, the first side wall passes upward through the circular channel at the bottom of the sealing ring to enter the area enclosed by the sealing ring, the second side wall enters downward from the opening at the top of the sealing ring to enter the area enclosed by the sealing ring and is sleeved on the outside of the first side wall, the upper end of the sealing ring enters the first connection area, the inner and outer side walls of the upper end of the sealing ring are respectively abutted against the third side wall and the lower edge of the upper cover, at this time, the sealing ring shrinks in the vertical direction, and the sealing cover body is in a closed state. In addition, the lower edge of the upper cover is set as a structure protruding from the lower side of the upper cover, which can wrap the end of the sealing ring inside, protecting the connection between the sealing ring and the upper cover from contamination.

[0035] like Figure 8 As shown, the upper cover 1 is provided with two installation cavities 14 protruding toward the lower cover 2, the upper part of the installation cavity 14 is provided with a first channel 141, and the lower part of the installation cavity 14 is provided with a second channel 142, and the connecting end 41 enters the installation cavity 14 through the first channel 141 and is connected with the connecting arm 62 that enters the installation cavity 14 through the second channel 142. The upper and lower ends of the sealing ring 3 are respectively connected to the lower side of the edge of the upper cover 1 and the upper side of the edge of the lower cover 2, and when the connecting end 41 drives the bottom plate 5 to move upward to shorten the distance between the upper cover 1 and the lower cover 2, the middle part of the sealing ring 3 is driven to protrude toward the outer shape by being squeezed.

[0036] In this embodiment, the sealing ring 3 is made of a flexible and deformable material. When no deformation occurs in a natural state, the inner circumference of the upper end of the sealing ring 3 is smaller than the outer circumference of the third side wall 13, and the inner circumference of the lower end of the sealing ring 3 is smaller than the outer circumference of the first side wall 51. The sealing ring is deformed when connected to the upper cover 1 and the lower cover 2, and has a force to shrink inward to restore its original state. It can cling to the first side wall and the second side wall to prevent the sealing ring from detaching from the upper cover or the lower cover, thereby ensuring the tightness of the connection.

[0037] The sealing cover disclosed in this embodiment has two states: open and closed. The connecting end 41 extends into the installation cavity 14 through the first channel 141 and is rotatably connected to the connecting arm 62 extending into the installation cavity 14 through the second channel 142 in the installation cavity 14. When the sealing cover is in the closed state, the operating lifting portion 42 rotates in the direction away from the upper cover 1, and the part of the connecting end 41 extending into the installation cavity 14 continues to move downward relative to the original state, driving the lower cover 2 to move downward, the sealing ring 3 stretches in the vertical direction, and the compressed part protruding outward in the horizontal direction to abut against the external medium is retracted, and the sealing cover is switched to the open state. When the sealing cover is in the open state, the operating lifting portion 42 rotates in the direction close to the upper cover 1, and the part of the connecting end 41 extending into the installation cavity 14 moves upward relative to the original state, driving the lower cover 2 to move upward, the sealing ring 3 is compressed in the vertical direction, and protrudes outward in the horizontal direction to abut against the external medium, and the sealing cover is switched to the closed state.

[0038] like Fig. 9 As shown, this embodiment includes the easily assembled sealing cover body as described above and a cup body 7 with an object storage space, the cup body has an opening, and the container cover body can be placed on the opening to seal the storage space. When the sealing cover body is in the open state, the sealing ring is inserted into the opening, and the lifting part 42 is operated to rotate in the direction close to the upper cover 1, so that the sealing ring 3 can be driven to be compressed in the up and down directions, and the middle part of the sealing ring protrudes outward in the horizontal direction and abuts against the inner wall of the opening, thereby achieving the effect of sealing the storage space.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

[0040] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
