Description

TECHNICAL FIELD

[0001] The utility model belongs to cup cover technical field, especially relate to a lifting structure of cover subassembly. BACKGROUND

[0002] When driving a car, a special cup is usually equipped on the car to facilitate the driver to drink. This special cup is often called a car cup. Since the driver needs to drive the car, the car cup can only be operated by one hand.

[0003] The earliest car cup is directly open to facilitate the driver to operate, and the driver can directly drink the water in the cup. However, the dust inside the car can easily fall directly into the cup from the opening, causing the water in the cup to mix with the dust. In order to solve the dust problem, the car cup is innovated in design and introduces a dust cover to improve the hygiene of use. After introducing the dust cover, how to conveniently open and close by one hand becomes the design focus of the car cup. Among them, the slide cover type cup cover using sliding mechanism to realize opening and closing is widely welcomed due to its convenience of one-handed operation.

[0004] For example, patent US10124942B2 provides a cover assembly that can be used on a car cup. Specifically, a first opening (through which the driver drinks the liquid in the cup) is provided on the cover body, a sliding block is slidably arranged on the cover body, a first positioning magnet is provided on the sliding block, and a second positioning magnet and a third positioning magnet are provided on the cover body. When the sliding block is slid to a position where the first positioning magnet and the second positioning magnet are attracted to each other, the sliding block is kept in the closed position under the action of the magnetic force, and the sliding block covers the first opening when it is in the closed position, so that the liquid in the cup will not flow out of the first opening. When the sliding block is slid to a position where the first positioning magnet and the third positioning magnet are attracted to each other, the sliding block is kept in the open position under the action of the magnetic force, and at this time the sliding block does not cover the first opening, and the first opening is exposed, so that the driver can drink the liquid in the cup through the first opening.

[0005] For example, patent CN217565584U provides a resilient opening and closing cup cover that can be used on a car cup, wherein a sliding groove is provided on the cover body, one end of the sliding groove is provided with a drinking opening, and a sliding cover is slidably arranged in the sliding groove; a closing positioning groove and an opening positioning groove are sequentially provided on the side wall of the sliding groove, and a resilient wall is protrudingly provided on one side of the sliding cover. When the sliding cover is slid to a position where the resilient arm is arranged in the closing positioning groove, the sliding cover covers the drinking opening so that the liquid in the cup will not flow out of the drinking opening. When the sliding cover is slid to a position where the resilient arm is in the opening positioning groove, the sliding cover does not cover the drinking opening, and the drinking opening is exposed, so that the driver can drink the liquid in the cup through the drinking opening.

[0006] However, although the ways in which they keep the sliding cover in the closed position and the open position are different, in their technical solutions, the bottom surface of the sliding cover and the top surface of the cover body are fitted during the sliding of the sliding cover on the cover body, and there is a magnetic force with attraction between the magnets arranged on the cover body and the sliding cover, which makes the sliding cover have a large friction during the sliding, thereby affecting the hand feeling of the driver and the use experience of the user.

[0039] In order to make the drawing simple, only the parts related to the present application are shown in the drawings, which do not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the parts with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one".

[0040] Embodiment 1

[0041] Reference Figure 1 、 2 , 16, the present embodiment provides a lifting structure of a cover assembly, which comprises a lid body 1, a sliding cover 2 and at least one lifting assembly. The lid body 1 is provided with a drinking port 4, and the drinking port 4 is a through hole connecting the first side and the second side of the lid body 1. The sliding cover 2 is slidably arranged on the first side of the lid body 1, and the sliding cover 2 is configured to slide between a closing position and an opening position on the lid body 1. When the sliding cover 2 is in the closing position, the sliding cover 2 covers the drinking port 4; when the sliding cover is in the opening position, the sliding cover 2 leaves the drinking port, and at the same time, the air hole 31 on the lid body 1 is in a ventilation state.

[0042] The lifting assembly comprises a lifting protrusion 24 and a groove 25, either of which is arranged on the surface of the cover body 1 facing the slide cover 2, and the other is arranged on the surface of the slide cover 2 facing the cover body 1. When the slide cover 2 is in the closed position, the lifting protrusion 24 is in the groove 25, and when the slide cover 2 slides away from the closed position, the lifting protrusion 24 moves out of the groove 25 to move the slide cover 2 relative to the cover body 1 in the first side direction of the cover body 1.

[0043] After the slide cover 2 slides away from the closed position, the lifting protrusion 24 moves out of the groove 25, so that the slide cover 2 slides between the lifting protrusion 24 and the cover body 1 instead of between the surfaces on the slide cover 2 and the cover body 1, thereby reducing the contact area during sliding and effectively reducing the friction during sliding, thereby enhancing the user experience.

[0044] The lifting structure of the cover assembly of the present embodiment will be further described below. For ease of understanding, the combination of the cover body 1 and the slide cover 2 will be referred to as the cover assembly. Figures 3 to 15 .

[0045] For ease of description, the combination of the cover body 1 and the slide cover 2 will be referred to as the cover assembly. The cover assembly is generally used in combination with a containing member. The cover body 1 in the cover assembly is threadedly connected or snap-connected to the opening of the containing member to form a container (in addition to the cover assembly and the containing member, other components can be added according to actual needs). For example, the containing member can be a cup body or a bottle body, and the cover assembly is connected to the cup opening of the cup body or the bottle opening of the bottle body to form a cup or a bottle with a cover. The contents in the containing member can be removed from the drinking opening 4 on the cover body 1.

[0046] When the user needs to pour out the contents (for example, the contents are water and the user needs to drink water), the user can slide the slide cover 2 on the cover body 1 to the open position, and the user can pour out the contents from the drinking opening 4. When the user does not need to pour out the contents (for example, the user does not need to drink water), the user can slide the slide cover 2 to the closed position, and in this state, the slide cover 2 covers the drinking opening on the cover body 1, thereby sealing the drinking opening, so that the container will not have the contents flowing out of the drinking opening 4 in the pouring state. It should be noted that the container is commonly used to contain liquids such as drinking water, but it can also be used to contain solid particles, and the type of contents in the container is not limited.

[0047] As shown in Figure 4 , when the cover body 1 is placed on a horizontal surface, the upper side of the cover body 1 is the first side of the cover body 1, the lower side of the cover body 1 is the second side of the cover body 1, the upward direction is the first side direction of the cover body 1, and the downward direction is the second side direction of the cover body 1.

[0048] The sliding cover 2 is provided with an elastic sealing member 3, and the sliding cover 2 drives the elastic sealing member 3 to move when sliding. When the sliding cover 2 is in the closed position, the sliding cover 2 covers the drinking opening 4 and the elastic sealing member 3 covers the drinking opening 4; when the sliding cover 2 is in the open position, the sliding cover 2 and the elastic sealing member 3 are both away from the drinking opening 4, and the air hole 31 on the cover body 1 is in the air state. When the sliding cover 2 slides to the closed position, the sliding cover 2 covers the drinking opening 4 on the cover body 1, and the elastic sealing member 3 covers the drinking opening 4, and the sliding cover 2 presses the elastic sealing member 3 at the drinking opening 4, thereby closing the drinking opening 4, so that the container does not leak in the pouring state.

[0049] The magnetic detachable connection between the sliding cover 2 and the cover body 1 can be, for example, as described in the background art, a first magnet 5 is arranged on the sliding cover 2, and a second magnet 6 is arranged on the cover body 1, the first magnet 5 and the second magnet 6 are attracted to each other, thereby attracting the sliding cover 2 to the cover body 1. Figure 16

[0050] When the sliding cover 2 is in the closed position, the sliding cover 2 presses the elastic sealing member 3 at the drinking opening 4 of the cover body 1, and the sliding cover 2 tightly presses the elastic sealing member 3 (and needs to deform the elastic sealing member 3), thereby realizing that the elastic sealing member 3 closes the drinking opening 4. There are many ways to realize how the sliding cover 2 can press the elastic sealing member 3 tightly at the drinking opening 4 of the cover body 1 when the sliding cover 2 is in the closed position, which is not limited. In this embodiment, the first magnet 5 and the second magnet 6 are used to generate a magnetic force that is large enough. In this way, no other structural improvements are needed for the cover assembly (such as the guide and downward pressing structure described below), and only the first magnet 5 and the second magnet 6 that can generate a larger magnetic force need to be replaced, which is friendly to the production process.

[0051] If the lifting assembly is not arranged, the elastic sealing member 3 will be tightly pressed on the cover body when the sliding cover 2 slides, which will increase a lot of frictional resistance and affect the user's hand feeling; and the arrangement of the lifting assembly can well solve the problem.

[0052] The cover body 1 has a mounting surface 7 facing the first side direction, the drinking opening 4 is arranged on the mounting surface 8, and the sliding cover 2 slides on the mounting surface 8. Preferably, in the direction perpendicular to the mounting surface 8, the distance that the sliding cover 2 moves away from the closed position under the action of the lifting assembly is greater than the distance that the elastic sealing member 3 protrudes from the sliding cover 2, so that the elastic sealing member 3 does not contact the mounting surface 8 after the sliding cover 2 moves away from the closed position, thereby reducing the sliding frictional resistance of the sliding cover 2 when sliding. Preferably, the end of the lifting protrusion 24 can be provided as a round head.

[0053] ​For ease of description, the stroke in which the sliding cover 2 slides from the closed position to the open position is called the first stroke, and the stroke in which the sliding cover 2 moves relative to the cover body 1 towards the first side of the cover body 1 under the guidance of the lifting structure is called the second stroke. The sliding direction of the sliding cover 2 during the process of sliding from the open position to the closed position is the first direction, and the sliding direction of the sliding cover 2 in the third stroke is the second direction. Preferably, the second stroke is a part of the first stroke and is located at the beginning of the first stroke.

[0054] Furthermore, a corresponding groove 26 is provided in the groove 25, with one end of the groove 26 communicating with the groove 25; when the sliding cover 2 slides on the cover body 1, the lifting protrusion 24 slides in the groove 26, and when the sliding cover 2 slides to the closed position, the lifting protrusion 24 slides into the groove 25. The groove 26 can guide the movement of the lifting protrusion 24.

[0055] Preferably, the groove 25 and the slide 26 are configured such that the distance the lifting protrusion 24 moves on the mounting surface 8 is less than 5 mm as it slides from the slide 26 into the groove 25.

[0056] Specifically, in this embodiment, a sliding groove 7 is provided on the first side of the cover body 1, and the bottom surface 8 of the sliding groove 7 is the aforementioned mounting surface 8. The drinking spout 4 is provided on the bottom surface 8 of the sliding groove 7. The sliding cover 2 is slidably disposed in the sliding groove 7. A closing positioning groove 9 and an opening positioning groove 10 are sequentially provided on at least one side wall of the sliding groove 7, and an elastic arm 11 is provided on at least one side of the sliding cover 2. When the elastic arm 11 is located in the closing positioning groove 9, the sliding cover 2 is in the closed position; when the elastic arm 11 is located in the opening positioning groove 10, the sliding cover 2 is in the open position. In this embodiment, preferably, a closing positioning groove 9 and an opening positioning groove 10 are sequentially provided on both side walls of the sliding groove 7, and an elastic arm 11 is provided on both sides of the sliding cover 2; more preferably, the elastic arms 11 on both sides of the sliding cover 2 can be symmetrically arranged, and the closing positioning grooves 9 and opening positioning grooves 10 on both side walls of the sliding groove 7 are also symmetrically arranged.

[0057] like Figure 9 As shown, the elastic arm 11 is connected to connecting arms 12 at both ends of the sliding cover 2 in the sliding direction. The other end of the connecting arm 12, which is not connected to the elastic arm 11, is connected to the sliding cover 2. That is, both ends of the elastic arm 11 are connected to the sliding cover 2 through connecting arms 12. There is a gap 13 between the elastic arm 11 and the connecting arm 12 and the side wall of the sliding cover 2. The gap 13 is used for the elastic deformation of the elastic arm 11 and the connecting arm 12. When the sliding cover 2 slides between the closed position and the open position, the elastic arm 11 elastically deforms towards the gap 13, so that the elastic arm 11 can slide out from the closed positioning groove 9 or the open positioning groove 10 and slide in the non-closed positioning groove area and the non-open positioning groove area on the side wall of the sliding groove 7.

[0058] The lifting protrusion 24 is arranged on the cover 2 (specifically, the lifting protrusion 24 is arranged on the surface of the cover 2 facing the groove bottom surface 8 of the sliding groove 7), and the groove 25 and the sliding groove 26 are arranged on the groove bottom surface 8 of the sliding groove 7. A plurality of lifting assemblies arranged in a direction perpendicular to the sliding direction of the cover 2 in the sliding groove 7 form a group, and a plurality of groups of lifting assemblies are arranged in the sliding direction of the cover 2 in the sliding groove 7. Specifically, in this embodiment, four lifting assemblies are arranged in the cover assembly, two lifting assemblies arranged in a direction perpendicular to the first direction form a group, and two groups of lifting assemblies are arranged in the first direction.

[0059] Embodiment 2

[0060] Referring to Figures 3 to 16 , the embodiment provides a lifting structure based on the cover assembly of embodiment 1.

[0061] In embodiment 1, by using the first magnet 5 and the second magnet 6 with a large enough attractive magnetic force, the cover 2 can press the elastic sealing member 3 against the groove bottom surface 8 of the sliding groove 7 when the cover 2 is in the closed position. However, this way has the disadvantage of high cost, that is, the first magnet 5 and the second magnet 6 with a large enough attractive magnetic force are high in cost themselves.

[0062] In this embodiment, the cover 2 is arranged to press the elastic sealing member 3 against the drinking opening 4 of the cover body 1 when the cover 2 is in the closed position by arranging the guide and pressing structure. Therefore, the first magnet 5 and the second magnet 6 only need to attract the cover 2 in the sliding groove 7, and do not need to provide additional magnetic force for the cover 2 to press the elastic sealing member 3 when the cover 2 is in the closed position, thereby saving cost.

[0063] The guide and pressing structure can guide the part of the cover 2 provided with the elastic sealing member 3 to move to the second side direction of the cover body 1 during the sliding of the cover 2 to the closed position, so that the cover 2 can press the elastic sealing member 3 against the groove bottom surface 8 of the sliding groove 7 when the cover 2 is in the closed position, thereby realizing the sealing of the drinking opening 4 by the elastic sealing member 3.

[0064] For the convenience of description, the stroke of the cover 2 from the open position to the closed position is referred to as the third stroke, and the stroke of the cover 2 sliding to the closed position under the guidance of the guide and pressing structure is referred to as the fourth stroke.

[0065] The fourth stroke is equal to the third stroke or a part of the third stroke. Preferably, the fourth stroke is a part of the third stroke and is located at the end of the third stroke.

[0066] The guiding and pressing structure comprises at least one guiding and pressing assembly, the guiding and pressing assembly comprises a first guiding part and a second guiding part, the first guiding part is arranged on the cover body 1, and the second guiding part is arranged on the sliding cover 2 and moves synchronously with the sliding cover 2. In the fourth stroke, the first guiding part and the second guiding part are in sliding connection, and the second guiding part is located in the direction of the second side of the first guiding part towards the cover body 1. The first guiding part and the second guiding part are configured to, in the fourth stroke, move towards the second side of the cover body 1 when the second guiding part slides under the limitation of the first guiding part.

[0067] Specifically, at least one of the first guiding part and the second guiding part is a guiding surface. When the first guiding part is the guiding surface, the first guiding part is a guiding surface arranged in the direction of the second side of the cover body 1; when the second guiding part is the guiding surface, the second guiding part is a guiding surface arranged in the direction of the first side of the cover body 1. The guiding surface is offset in the first direction towards the second side of the cover body 1, and the specific offset manner can be offset in a planar manner (i.e. an inclined plane), offset in a curved surface manner (i.e. the farther the curved surface is in the first direction, the closer it is to the second side of the cover body 1), or offset in a combination of a planar and a curved surface manner, etc., and the specific manner is not limited.

[0068] When the first guiding part on the cover body 1 is the guiding surface, in the fourth stroke, the second guiding part moves synchronously with the sliding cover 2, and the second guiding part slides against the guiding surface (i.e. the first guiding part) when the sliding cover 2 slides in the first direction. Since the guiding surface is offset in the first direction towards the second side of the cover body 1, the second guiding part will gradually move towards the second side of the cover body 1 under the limitation of the guiding surface, thereby driving the sliding cover 2 to move towards the second side of the cover body 1.

[0069] When the second guiding part on the sliding cover 2 is the guiding surface, in the fourth stroke, the guiding surface will abut against the first guiding part when the sliding cover 2 slides in the first direction. Since the guiding surface is offset in the first direction towards the second side of the cover body 1, in the process of moving in the first direction with the sliding cover 2, the part of the guiding surface abutting against the second guiding part is gradually offset towards the first side of the cover body 1 relative to the sliding cover 2. Since the first guiding part is fixed on the cover body 1 and does not change in position, in the process of moving in the first direction with the sliding cover 2, the guiding surface will gradually move towards the second side of the cover body 1, thereby driving the sliding cover 2 to move towards the second side of the cover body 1.

[0070] When the first guiding part on the cover body 1 and the second guiding part on the sliding cover 2 are both guiding surfaces, in the fourth stroke, in the process of moving in the first direction with the sliding cover 2, the second guiding part slides along the first guiding part and gradually moves towards the second side of the cover body 1, thereby driving the sliding cover 2 to move towards the second side of the cover body 1.

[0071] In the fourth stroke, the part of the sliding cover 2 provided with the elastic sealing member 3 moves in the direction perpendicular to the mounting surface 8 by a distance smaller than the distance by which the elastic sealing member 3 protrudes from the sliding cover 2, so that the sliding cover 2 can press the elastic sealing member 3 against the drinking opening 4 of the cover body 1 in the closed position and press the elastic sealing member 3 to be elastically deformed, thereby sealing the drinking opening 4. The distance by which the elastic sealing member 3 protrudes from the sliding cover 2 is small, so the part of the sliding cover 2 provided with the elastic sealing member 3 moves in the direction perpendicular to the mounting surface 8 by a small distance in the fourth stroke, which is generally selected to be within 5 mm, preferably about 0.6 mm; of course, the specific distance by which the part of the sliding cover 2 provided with the elastic sealing member 3 moves in the direction perpendicular to the mounting surface 8 in the fourth stroke also needs to be adjusted according to the actual situation.

[0072] The sliding distance of the sliding cover 2 in the process of sliding from the open position to the closed position is small, so the part of the sliding cover 2 provided with the elastic sealing member 3 moves in the plane parallel to the mounting surface 8 by a small distance in the fourth stroke, which is generally selected to be within 10 mm, preferably about 2 mm.

[0073] In this way, the arrangement of the wire pressing structure does not affect the user's hand feeling during the process of pushing the sliding cover 2.

[0074] The area in which the sliding cover 2 slides in the sliding groove 7 in the second stroke is the same as the area in which the sliding cover 2 slides in the sliding groove 7 in the fourth stroke, and the sliding direction of the sliding cover 2 in the second stroke is opposite to the sliding direction of the sliding cover 2 in the fourth stroke.

[0075] The guide pressing structure in the present embodiment includes a first guide pressing component, a second guide pressing component, and a third guide pressing component, wherein the first guide pressing component plays a main guide pressing role (the guide pressing role is the role of moving the sliding cover 2 to the second side of the cover body 1 in the fourth stroke), and the fourth stroke refers to the stroke in which the sliding cover 2 slides under the limitation of the first guide pressing component in the process of sliding from the open position to the closed position.

[0076] The parts of the inner side wall of the sliding groove 7 located on both sides of the sliding direction of the sliding cover 2 are sliding inner side walls 14, and the closing positioning groove 9 and the opening positioning groove 10 are arranged in the sliding inner side walls 14; the parts of the outer side wall of the sliding cover 2 located on both sides of the sliding direction of the sliding cover 2 are sliding outer side walls 15.

[0077] The first guiding and pressing assembly comprises a guiding groove 16 and a guiding protrusion 17, either of which is arranged on the sliding inner side wall 14, and the other is arranged on the sliding outer side wall 15. During the sliding of the sliding cover 2 from the open position to the closed position, at least part of the sliding process, the guiding protrusion 17 is slidably connected in the guiding groove 16; specifically, the guiding protrusion 17 is slidably connected in the guiding groove 16 in the fourth stroke. The guiding groove 16 is offset to the second side of the cover body 1 in the first direction.

[0078] Specifically, in the present embodiment, the two sliding inner side walls 14 of the sliding groove 7 are respectively provided with a first guiding and pressing assembly in cooperation with the corresponding sliding outer side wall 15. Moreover, when the sliding cover 2 is in the closed position, there is a first guiding and pressing assembly on each side of the first direction of the drinking opening 4; thus, when the sliding cover 2 is in the closed position, the first guiding and pressing assemblies on both sides of the drinking opening 4 can well exert force on the sliding cover 2, so that the sliding cover 2 presses the elastic sealing member 3 at the drinking opening 4, so that the elastic sealing member 3 seals the drinking opening 4, preventing the contents in the container from flowing out. Among them, in the first guiding and pressing assembly, the inner side wall of the guiding groove 16 on the sliding cover 2 close to the second side of the cover body 1 (that is, the inner side wall of the guiding groove 16 facing the first side of the cover body 1, which is the inner side wall of the guiding protrusion 17 on the second side of the cover body 1) is the guiding surface mentioned above.

[0079] The end of the guiding groove 16 in the first direction can be provided with an opening, and the opening is used for the guiding protrusion 17 to slide into the guiding groove 16 from the opening during the sliding of the sliding cover 2 in the first direction.

[0080] The part of the inner side wall of the sliding groove 7 located at both ends of the sliding direction of the sliding cover 2 is the end inner side wall, and the drinking opening 4 is arranged on the groove bottom surface 8 of the sliding groove 7 close to one of the end inner side walls, which is a specific end inner side wall 18. The part of the outer side wall of the sliding cover 2 located at both ends of the sliding direction of the sliding cover 2 is the end outer side wall, and the end outer side wall facing the specific end inner side wall 18 is a specific end outer side wall 19.

[0081] The second guiding and pressing assembly is arranged between the specific end inner side wall 18 and the specific end outer side wall 19, and the second guiding and pressing assembly comprises a clamping groove 20 and a clamping block 21, either of which is arranged on the specific end inner side wall 18, and the other is arranged on the specific end outer side wall 19. During the sliding of the sliding cover 2 from the open position to the closed position, the clamping block 21 is inserted into the clamping groove 20; and the clamping block 21 and the clamping groove 20 are configured such that, during the insertion of the clamping block 21 into the clamping groove 20, the clamping block 21 / clamping groove 20 arranged on the specific end outer side wall 19 moves to the second side of the cover body 1 under the limitation of the clamping groove 20 / clamping block 21 arranged on the specific end inner side wall 18.

[0082] Specifically, in the present embodiment, the clamping groove 20 is arranged on the side wall of the sliding groove 7, and the clamping block 21 is arranged on the end of the sliding cover 2. In the second guiding and pressing assembly, the inner wall surface of the clamping groove 20 facing the second side of the cover body 1 is the guiding surface, and the outer surface of the clamping block 21 facing the first side of the cover body 1 is the guiding surface.

[0083] The arrangement of the second guiding and pressing assembly can not only provide guiding and pressing effect in the fourth stroke of the sliding cover 2, but also can play a fixing role. When the sliding cover 2 is in the closed position, the second guiding and pressing assembly fixes the end of the sliding cover 2 (specifically, the end corresponding to the drinking opening 4). For example, when the content is hot water, hot gas is easy to push the elastic sealing member 3 away from the end of the sliding cover 2 through the drinking opening 4, thereby breaking the seal and causing leakage. The arrangement of the second guiding and pressing assembly between the outer side wall 19 of the specific end of the sliding cover 2 and the inner side wall 18 of the specific end of the cover body 1 can effectively prevent such leakage.

[0084] The third guiding and pressing assembly includes a clamping piece 22 protruding from the groove bottom surface 8 of the sliding groove 7 and a clamping block 23 arranged on the sliding cover 2. The clamping piece 22 protrudes from the groove bottom surface 8 to the first side of the cover body 1 by a certain distance and then bends to the second direction, so that the clamping piece 22 and the groove bottom surface 8 cooperate to form a clamping groove facing the second direction. In the process of sliding the sliding cover 2 from the open position to the closed position, the clamping block 23 extends into the clamping groove; and the clamping block 23 and the clamping groove are configured such that, in the process of the clamping block 23 extending into the clamping groove, the clamping block 23 moves to the second side of the cover body 1 under the limitation of the inner side wall of the clamping groove facing the second side of the cover body 1. In the third guiding and pressing assembly, the inner wall surface of the clamping groove facing the second side of the cover body 1 is the guiding surface, and the outer surface of the clamping block 23 facing the first side of the cover body 1 is the guiding surface.

[0085] As shown in Figure 12 The clamping block 23 can be arranged at the connection between the connecting arm 12 and the sliding cover 2. The clamping piece 22 can protrude from the groove bottom surface 8 and extend into the gap 13, that is, the clamping piece 22 is arranged in the gap 13. Preferably, two third guiding and pressing assemblies can be arranged between the cover body 1 and the sliding cover 2, and two clamping pieces 22 are arranged on the groove bottom surface 8 of the sliding groove 7.

[0086] The arrangement of the third guiding and pressing assembly can not only provide guiding and pressing effect in the fourth stroke of the sliding cover 2, but also can play a role in preventing the sliding cover 2 from being separated from the cover body 1. When the container with the cover assembly is dropped from a high place (for example, the user accidentally collides with others while holding the container in his hand, or the container falls from the table after being collided), the arrangement of the third guiding and pressing assembly can effectively prevent the sliding cover 2 from being separated from the cover body 1. If the sliding cover 2 is separated from the cover body 1, it is easy to be lost because of being difficult to find due to its small size.

[0087] The sliding cover 2 and the cover body 1 are assembled together, and one of them can be replaced by the user at will, for example, when one of them is damaged, the damaged one is replaced, and further for example, the sliding cover 2 can sometimes be lost (the cover body 1 is connected to the containing member and is large in size, and is not easy to lose in comparison) and needs to be replaced. In order to facilitate the user to assemble the sliding cover 2 and the cover body 1, the sliding cover 2 can be designed as a central symmetric structure, in this way, the user does not need to distinguish the two ends of the sliding cover 2 in the sliding direction when installing the sliding cover 2, and the user is facilitated to install. The sliding cover 2 is a central symmetric structure, and the guide groove 16, the clamping block 21, the clamping block 23, the elastic sealing member 3 and the like on the sliding cover 2 all need to be centrally symmetrically arranged.

[0088] The first guide and pressing assembly, the second guide and pressing assembly and the third guide and pressing assembly all have the guide and pressing function, and therefore in other embodiments, only any one or any two of them can be provided, and in other embodiments, the guide and pressing structure specifically comprises several guide and pressing assemblies (the first guide and pressing assembly, the second guide and pressing assembly and the third guide and pressing assembly), and which several guide and pressing assemblies are included can be set according to the actual situation, for example Figure 17 The cover assembly shown in FIG. 8 only comprises the first guide and pressing assembly and the second guide and pressing assembly.

[0089] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments. Even if various changes are made to the utility model, if the changes belong to the scope of the claims of the utility model and equivalent technologies, they still fall within the protection scope of the utility model.
