Description

Technical Field

[0001] The present invention relates to the technical field of liquid containers, in particular to a container cover and a liquid container. Background Art

[0002] At present, the cup cover of a portable water cup such as a sports water cup generally includes a first cover body and a second cover body, and is usually equipped with a self-locking component for locking the first cover body and the second cover body. When the first cover body and the second cover body pass through the self-locking component, the risk of the first cover body being opened by mistake can be reduced. However, in the process of opening the first cover body, the user not only needs to unlock the first cover body and the second cover body, but also needs to unlock the self-locking component. There is a problem that the user has to operate the self-locking component to unlock the problem of complexity, which is not convenient for one-handed operation and reduces the user experience. Summary of the invention

[0003] The present application provides a container cover and a liquid container, which are used to solve the problem that in the process of opening the first cover body of the liquid container cover, it is complicated for the user to operate the self-locking component to unlock, which is inconvenient for one-handed operation and reduces the user experience.

[0004] In a first aspect, the present application provides a container cover, the container cover comprising: a cover body, the cover body comprising a first cover body and a second cover body rotatably connected;

[0005] A locking key, wherein the locking key is movably connected to the cover body, and the first cover body and the second cover body are locked and matched by the locking key;

[0006] a first limiting member, the first limiting member is movably connected to the cover body, and the first limiting member has a locking position and an unlocking position;

[0007] Wherein, in the locking position, the first limiter is used to limit the movement of the locking key relative to the cover body, so as to limit the first cover body from releasing the locking cooperation with the second cover body;

[0008] In the unlocked position, the first limit member releases the restriction on the movement of the locking key relative to the cover body, the locking key can release the locking cooperation between the first cover body and the second cover body, and the first limit member is locked with the cover body to limit the movement of the first limit member relative to the cover body.

[0009] In this solution, the cover body is provided with a first limit member. When the first limit member is driven to move to the unlocked position, the first limit member cooperates with the cover body to limit the movement of the first limit member relative to the cover body. Even if the first limit member can be maintained in the unlocked position to avoid the locking key, the user can drive the locking key to move relative to the cover body with one hand. That is, the user does not need to limit the first limit member to the locked position with his hand while driving the locking key to move, so as to simplify the unlocking process so that the user can unlock with one hand, thereby improving the user experience.

[0010] At the same time, when the first limit member is in the locking position, the first limit member can limit the movement of the locking key relative to the cover body, so as to reduce the risk of accidentally touching the locking key and causing the first cover body and the second cover body to be unlocked, thereby reducing the risk of accidentally opening the first cover body, thereby reducing the risk of scalding the user or wetting the clothes, improving the safety of the container cover, and further improving the user experience.

[0011] In this embodiment, the cover body also includes a second limit member, and the second limit member is movably connected to the first cover body. In the unlocked position, the first limit member and the second limit member are locked together to limit the movement of the first limit member relative to the cover body. In the locked position, the first limit member and the second limit member are released from the locked cooperation.

[0012] In this solution, the cover body is provided with a second limit member, and the second limit member is movably connected to the first cover body so that the second limit member can move relative to the first limit member, thereby enabling the first limit member to lock or unlock with the second limit member, which is beneficial to improving the feasibility and reliability of the first limit member being able to switch to the unlocked position, the locked position or the locked position.

[0013] In this solution, the first limiting member includes a first clamping portion protruding along the height direction of the container cover, and the second limiting member includes a second clamping portion. During the process of the first limiting member moving from the locked position to the unlocked position, the first limiting member can move radially along the container cover relative to the cover body to drive the second limiting member to move along the height direction of the container cover so that the first clamping portion is clamped with the second clamping portion.

[0014] In this solution, the second position limiter is provided with an avoidance hole. During the movement of the first position limiter from the locked position to the unlocked position, the first position limiter interacts with the second position limiter, that is, the first clamping part can drive the second position limiter to move away from the second cover body along the height direction of the container cover during the movement, so that the first clamping part extends through the avoidance hole and is clamped with the second clamping part, so as to improve the feasibility and reliability of the clamping of the first clamping part and the second clamping part. At the same time, in the unlocked position, the risk of the first position limiter moving relative to the first cover body is reduced through the clamping cooperation of the first clamping part and the second clamping part, and the stability of the first position limiter in the unlocked position is improved.

[0015] In this solution, the first clamping portion includes a first inclined surface, and the second clamping portion includes a second inclined surface. During the movement from the locked position to the unlocked position, the first inclined surface pushes the second clamping portion to move along the height direction of the container cover through the second inclined surface, and the first clamping portion is clamped with the second clamping portion.

[0016] In this solution, the first clamping part and the second clamping part are provided with inclined surfaces that can slide with each other, so that the first limiter can exert a force along the height direction of the container cover on the second limiter during the movement, so that the second limiter can move relative to the first cover body along the height direction of the container cover, so that the first limiter and the second limiter can be smoothly clamped. At the same time, the above clamping method has the advantages of simple structure, low cost, good stability, etc.

[0017] In this solution, the first stopper also includes an operating portion and a body provided with the first clamping portion, the first cover body includes an outer cover and an inner cover that are fixedly connected, a receiving cavity is provided between the outer cover and the inner cover, the receiving cavity is used to receive the body, the inner wall of the outer cover is provided with a groove, the body includes a first protrusion, and the first protrusion can slide along the groove;

[0018] The outer cover is provided with a through hole communicating with the accommodating cavity, and the operating part can extend through the through hole.

[0019] In this solution, the operating part extends out of the first cover body through the through hole so that the user can drive the first limiter. When the first limiter switches between the unlocked position and the locked position, the body slides in the accommodating cavity, and the first protrusion slides along the groove. The groove can limit the first limiter from continuing to move radially along the container cover when it is in the locked position or the unlocked position, so as to reduce the risk of over-movement of the first limiter.

[0020] In this solution, the container cover further includes a first elastic member and a second elastic member. Along the radial direction of the container cover, one end of the first elastic member is elastically connected to the first limit member, and the other end is elastically connected to the first cover body;

[0021] Along the height direction of the container cover, one end of the second elastic member is elastically connected to the first cover body, and the other end is elastically connected to the second limiting member.

[0022] In this solution, a first elastic member is arranged between the first cover body and the first limiting member. After the first clamping portion and the second clamping portion are released from clamping, the first limiting member can automatically reset to the locking position under the action of the first elastic member, so that the cover body can be automatically locked. That is, the user only needs to drive the first cover body toward the second cover body to make the first limiting member automatically move to the locking position, and then the first cover body and the second cover body are locked and matched, thereby reducing the risk of accidental opening and reducing the steps of separately locking the traditional container cover, which is convenient for user operation and further improves the user experience.

[0023] In addition, during the process of the first limit member moving from the locked position to the unlocked position and the sliding cooperation between the first inclined surface and the second inclined surface, the second elastic member is compressed under the action of the first limit member, and then when the first clamping portion is completely extended through the avoidance hole, the second limit member moves downward along the height direction of the container cover under the action of the rebound force of the second elastic member, so that the first clamping portion can be fully engaged with the second clamping portion, so as to improve the stability and firmness of the clamping between the first clamping portion and the second clamping portion, and greatly reduce the risk of the first clamping portion and the second clamping portion being released from the clamping cooperation.

[0024] In this embodiment, the second cover body is provided with a reset assembly, and in the process of moving from the unlocking position to the locking position, the reset assembly is used to drive the second limit member to move along the height direction of the container cover to release the engagement between the first limit member and the second limit member.

[0025] In this solution, a reset assembly is provided on the cover body, so that during the movement from the unlocked position to the locked position, the second limit member can automatically move upward along the height direction of the container cover under the action of the reset assembly, thereby improving the reliability of the first limit member and the second limit member being released from the engagement.

[0026] In this solution, the reset component includes a reset member and a third elastic member, and the reset member is movably connected to the second cover body. Along the height direction of the container cover, one end of the third elastic member is connected to the reset member, and the other end is connected to the second cover body. During the locking cooperation between the first cover body and the second cover body, the second limit member can drive the reset member to move toward the second cover body along the height direction of the container cover. Under the action of the rebound force of the third elastic member, the reset member can drive the second limit member to move away from the second cover body along the height direction of the container cover, so that the second limit member and the first limit member are released from cooperation.

[0027] In this solution, a reset member and a third elastic member are provided on the first cover body. During the movement from the unlocked position to the locked position, the second limit member can automatically move upward along the height direction of the container cover under the action of the reset member and the third elastic member, so that the first limit member and the second limit member can be released from the engagement, thereby eliminating the need for the user to manually drive the first limit member to move to the locked position, so that the cover body can be automatically locked, thereby improving the user experience.

[0028] In this solution, the first cover body is provided with a first installation groove, the second limiter has a first bottom wall, the first cover body has a second bottom wall, the second limiter is installed inside the first installation groove, and there is a preset distance between the first bottom wall and the second bottom wall;

[0029] The reset assembly further includes a reset seat, the reset seat is movably connected to the second cover body, the reset seat has an installation cavity, a part of the reset member is located in the installation cavity and can move in the installation cavity;

[0030] During the locking cooperation between the first cover body and the second cover body, the second bottom wall abuts against the reset seat.

[0031] In this solution, during the locking engagement of the first cover body and the second cover body, the second bottom wall of the first cover body abuts against the reset seat, which can increase the contact area between the first cover body and the reset assembly, and is beneficial to improving the stability and reliability of the interaction between the first cover body and the reset assembly to enable the other to move along the height direction of the container cover.

[0032] In this embodiment, the second cover body is provided with a second mounting groove, the second mounting groove is used to install the reset seat, the side wall of the second mounting groove is provided with a limiting hole, the reset seat is provided with a second protrusion, and the second protrusion can slide in the limiting hole along the height direction of the container cover.

[0033] In this solution, during the process of locking or unlocking the first cover body and the second cover body, the second protrusion can slide in the limiting hole along the height direction of the container cover, reducing the risk of the reset seat detaching from the second mounting groove, which is beneficial to improving the structural stability of the cover body.

[0034] In this embodiment, the first cover body includes an inner cover, an outer cover and a fourth elastic member, the locking key is rotatably connected to the inner cover, and the locking key includes a pressing portion and a first hook, one end of the fourth elastic member is elastically connected to the inner cover, and the other end is elastically connected to the pressing portion, and the first hook is used to engage with the second cover body;

[0035] The first limiting member has a limiting portion, and in the locking position, the pressing portion abuts against the limiting portion to limit the locking key from being pressed.

[0036] The second cover body includes a second hook. In the locked position, the first hook is engaged with the second hook to limit the first cover body from being unlocked from the second cover body. When the first limiter is in the unlocked position, the user presses the pressing portion to compress the fourth elastic member, thereby causing the locking key to rotate relative to the first cover body, thereby releasing the engagement between the first hook and the second hook, so that the first cover body and the second cover body are unlocked. The connection by the hook engagement method is conducive to improving the stability and reliability of the locking engagement between the first cover body and the second cover body.

[0037] The second aspect of the present application further provides a liquid container, the liquid container comprising a container body and a container cover, wherein the container cover is mounted on the container body, wherein the container cover is the container cover described above.

[0038] In this solution, when the container cover is used for a liquid container, after the first limit member moves to the unlocked position, the first limit member cooperates with the cover body so that the first limit member can be maintained in the unlocked position avoiding the locking key, so that the user does not need to use his hand to limit the first limit member to the locked position while driving the locking key to move, thereby simplifying the unlocking process of the container cover so that the user can operate it with one hand, thereby improving the user's experience of using the container cover, and further improving the user's experience of using the liquid container.

[0105] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0106] In a specific embodiment, the present application is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0107] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0108] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0109] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0110] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0111] The present application embodiment provides a container cover, such as Figure 1-Figure 5 As shown, the container cover comprises a cover body 1, a locking key 2 and a first stopper 3, wherein the cover body 1 comprises a first cover body 11 and a second cover body 12 which are rotatably connected. The locking key 2 is movably connected to the cover body 1, and the first cover body 11 and the second cover body 12 are locked and matched by the locking key 2. The first stopper 3 is movably connected to the cover body 1, and the first stopper 3 has a locked position and an unlocked position.

[0112] Among them, Figure 1 As shown, in the locked position, the first limiter 3 is used to limit the movement of the lock key 2 relative to the cover body 1, so as to limit the release of the locking cooperation between the first cover body 11 and the second cover body 12. Figure 3 As shown, in the unlocked position, the first limit member 3 releases the restriction on the movement of the locking key 2 relative to the cover body 1, the locking key 2 can release the locking cooperation of the first cover body 11 and the second cover body 12, and the first limit member 3 is locked with the cover body 1 to limit the movement of the first limit member 3 relative to the cover body 1.

[0113] When the first cover 11 and the second cover 12 need to be unlocked, that is, when the first cover 11 needs to be opened, the first limit member 3 is driven to move from Figure 1 Move the locking position shown to Figure 3 The unlocked position shown in the figure makes the first limit member 3 lock with the cover body 1, thereby limiting the movement of the first limit member 3 relative to the cover body 1, so that the locking key 2 can move relative to the cover body 1, and then the user can drive the locking key 2 to move relative to the cover body 1 to release the restriction on the locking cooperation between the first cover body 11 and the second cover body 12, so that the first cover body 11 can move relative to the second cover body 12 to open the first cover body 11, that is, Figure 5 The cover body 1 is shown.

[0114] Therefore, the cover body 1 is provided with a first limit member 3. When the first limit member 3 is driven to move to the unlocking position, the first limit member 3 cooperates with the cover body 1 to limit the movement of the first limit member 3 relative to the cover body 1. Even if the first limit member 3 can be maintained in the unlocking position to avoid the locking key 2, the user can drive the locking key 2 to move relative to the cover body 1 with one hand, that is, the user does not need to limit the first limit member 3 to the locking position with his hand while driving the locking key 2 to move, so as to simplify the unlocking process so that the user can unlock with one hand, thereby improving the user experience.

[0115] At the same time, when the first limit member 3 is in the locked position, the first limit member 3 can limit the movement of the locking button 2 relative to the cover body 1, so as to reduce the risk of accidentally touching the locking button 2 and causing the first cover body 11 and the second cover body 12 to release the locking cooperation, thereby reducing the risk of accidentally opening the first cover body 11, thereby reducing the risk of causing users to be scalded or clothes to get wet, improving the safety of using the container cover, and further improving the user's experience.

[0116] In a possible implementation, Figure 1-Figure 5 As shown, the cover body 1 further includes a second stopper 4, and the second stopper 4 is movably connected to the first cover body 11. In the unlocked position, the first stopper 3 and the second stopper 4 are locked and matched to limit the movement of the first stopper 3 relative to the cover body 1. In the locked position, the first stopper 3 and the second stopper 4 are unlocked.

[0117] In this embodiment, the cover body 1 is provided with a second limit member 4, and the second limit member 4 is movably connected to the first cover body 11, so that the second limit member 4 can move relative to the first limit member 3, and then the first limit member 3 can be locked or unlocked with the second limit member 4, which is beneficial to improve the feasibility and reliability of the first limit member 3 being able to switch to the unlocked position, the locked position or the locked position.

[0118] In another possible embodiment, a matching portion, such as a protruding or recessed matching structure, may be provided on the first cover body 11, and when the first limit member 3 moves to the unlocked position, the first limit member 3 cooperates with the matching portion to limit the first limit member 3 to the unlocked position.

[0119] In a possible implementation, Figure 1 , Figure 3 and Figure 4 As shown, the first limiting member 3 includes a first clamping portion 321 protruding along the height direction of the container cover, and the second limiting member 4 includes a second clamping portion 41. During the movement of the first limiting member 3 from the locked position to the unlocked position, the first limiting member 3 can move radially along the container cover relative to the cover body 1 to drive the second limiting member 4 to move along the height direction of the container cover, so that the first clamping portion 321 is clamped with the second clamping portion 41.

[0120] Specifically, if Figure 2 , Figure 3 and Figure 5 As shown, the second stopper 4 is provided with an avoidance hole 42. Figure 1 Move the locking position shown to Figure 3 During the process of the unlocking position shown, the first stopper 3 interacts with the second stopper 4, that is, the first clamping portion 321 can drive the second stopper 4 to move away from the second cover body 12 along the height direction of the container cover during the movement, so that the first clamping portion 321 extends through the avoidance hole 42 and is clamped with the second clamping portion 41, so as to improve the feasibility and reliability of the clamping of the first clamping portion 321 and the second clamping portion 41. At the same time, in the unlocking position, the risk of the first stopper 3 moving relative to the first cover body 11 is reduced through the clamping cooperation of the first clamping portion 321 and the second clamping portion 41, and the stability of the first stopper 3 in the unlocking position is improved.

[0121] In a possible implementation, Figure 3 and Fig.12 As shown, the first clamping portion 321 includes a first inclined surface 321a, and the second clamping portion 41 includes a second inclined surface 411. During the movement from the locked position to the unlocked position, the first inclined surface 321a pushes the second clamping portion 41 to move along the height direction of the container cover through the second inclined surface 411, and the first clamping portion 321 is clamped with the second clamping portion 41.

[0122] During the process of the first limit member 3 moving from the locked position to the unlocked position, that is, the process of the first clamping portion 321 moving toward the second clamping portion 41, the first inclined surface 321a of the first clamping portion 321 and the second inclined surface 411 of the second clamping portion 41 slide relative to each other to drive the second limit member 4 to move away from the second cover body 12 along the height direction of the container cover, that is, move upward, so that the first clamping portion 321 can extend through the avoidance hole 42 and clamp with the second clamping portion 41.

[0123] Therefore, the first clamping portion 321 and the second clamping portion are provided with inclined surfaces that can slide with each other, so that the first stopper 3 can exert a force along the height direction of the container cover on the second stopper 4 during the movement, so that the second stopper 4 can move along the height direction of the container cover relative to the first cover body 11, so that the first stopper 3 and the second stopper 4 can be smoothly clamped. At the same time, the above-mentioned clamping method has the advantages of simple structure, low cost, good stability, etc.

[0124] In a possible implementation, Figure 1 and Figure 4 As shown, the container cover further includes a first elastic member 5 and a second elastic member 6. Along the radial direction of the container cover, one end of the first elastic member 5 is elastically connected to the first stopper 3, and the other end is elastically connected to the first cover body 11. Along the height direction of the container cover, one end of the second elastic member 6 is elastically connected to the first cover body 11, and the other end is elastically connected to the second stopper 4.

[0125] When the first stopper 3 moves from the locked position to the unlocked position, the first elastic member 5 is compressed. Meanwhile, when the second stopper 4 moves upward from the position engaged with the first stopper 3 along the height direction of the container cover, the second elastic member 6 is compressed.

[0126] When the first cover 11 needs to be switched to Figure 7 In the covered state shown, during the process of driving the first cover body 11 to move toward the second cover body 12, the second limit member 4 can automatically move upward along the height direction of the container cover and compress the second elastic member 6, so that the first clamping portion 321 and the second clamping portion 41 are released from the clamping fit, and then the first clamping portion 321 can move away from the second limit member 4 in the radial direction of the container cover through the avoidance hole 42, and then the first limit member 3 moves away from the second limit member 4 in the radial direction of the container cover under the action of the rebound force of the first elastic member 5, so that the first limit member 3 can automatically move to the locked position, thereby limiting the movement of the locking key 2, so that the first cover body 11 and the second cover body 12 are locked and matched.

[0127] Therefore, a first elastic member 5 is arranged between the first cover body 11 and the first limiting member 3. After the first clamping portion 321 and the second clamping portion 41 are disengaged, the first limiting member 3 can be automatically reset to the locked position under the action of the first elastic member 5, so that the cover body 1 can be automatically locked. That is, the user only needs to drive the first cover body 11 toward the second cover body 12 to make the first limiting member 3 automatically move to the locked position, and then the first cover body 11 and the second cover body 12 are locked and matched, thereby reducing the risk of accidental opening and reducing the steps of separately locking the traditional container cover, which is convenient for user operation and further improves the user experience.

[0128] In addition, during the process of the first limit member 3 moving from the locked position to the unlocked position and the sliding cooperation between the first inclined surface 321a and the second inclined surface 411, the second elastic member 6 is compressed under the action of the first limit member 3, and then when the first clamping portion 321 is completely extended through the avoidance hole 42, the second limit member 4 moves downward along the height direction of the container cover under the action of the rebound force of the second elastic member 6, so that the first clamping portion 321 can be completely engaged with the second clamping portion 41, so as to improve the stability and firmness of the clamping between the first clamping portion 321 and the second clamping portion 41, and greatly reduce the risk of the first clamping portion 321 and the second clamping portion 41 being released from the clamping cooperation.

[0129] In a possible implementation, Figure 3 , Fig. 9 and Fig.14 As shown, the first stopper 3 also includes an operating portion 31 and a body 32 provided with a first clamping portion 321. The first cover body 11 includes an outer cover 111 and an inner cover 112 that are fixedly connected. There is a receiving cavity between the outer cover 111 and the inner cover 112. The receiving cavity is used to receive the body 32. The inner wall of the outer cover 111 is provided with a groove 111a. The body 32 includes a first protrusion 322, and the first protrusion 322 can slide along the groove 111a. The outer cover 111 is provided with a through hole communicating with the receiving cavity, and the operating portion 31 can extend through the through hole.

[0130] In this embodiment, the operating portion 31 extends out of the first cover body 11 through the through hole so that the user can drive the first stopper 3. When the first stopper 3 switches between the unlocked position and the locked position, the body 32 slides in the accommodating cavity, and the first protrusion 322 slides along the groove 111a. The groove 111a can limit the first stopper 3 from continuing to move along the radial direction of the container cover when it is in the locked position or the unlocked position, so as to reduce the risk of over-movement of the first stopper 3. Specifically, when the first stopper 3 switches the locked position, the first stopper 3 is driven to move by the rebound force of the first elastic member 5. When the first stopper 3 moves to the locked position, the first protrusion 322 and the groove 111a can limit the first stopper 3 from continuing to move under the action of the first elastic member 5, so as to reduce the risk of damage caused by collision with other components due to continued movement of the first stopper 3, which is conducive to improving the reliability and life of the cover body 1.

[0131] In a possible implementation, Figure 2-Figure 4 As shown, the first cover body 11 includes a fourth elastic member 113 installed in the accommodating cavity, the locking key 2 is rotatably connected to the inner cover 112, and the locking key 2 includes a pressing portion 21 and a first hook 22, one end of the fourth elastic member 113 is elastically connected to the inner cover 112, and the other end is elastically connected to the pressing portion 21, and the first hook 22 is used to be connected to the second cover body 12.

[0132] Specifically, the cover body 1 further includes a connecting member 13 and a torsion spring 14, so that the first cover body 11 is rotatably connected with the second cover body 12, and the second cover body 12 includes a second hook 126. In the locked position, the first hook 22 is engaged with the second hook 126 to limit the first cover body 11 and the second cover body 12 from releasing the locking fit. When the first limit member 3 is located at the unlocked position, the user presses the pressing portion 21 to compress the fourth elastic member 113, so that the locking key 2 rotates relative to the first cover body 11, and then the first hook 22 is released from the second hook 126, so that the first cover body 11 and the second cover body 12 are released from the locking fit, and then the first cover body 11 automatically pivots upward under the action of the torsion spring 14, so that the first cover body 11 is opened.

[0133] The connecting member 13 may be a rotating shaft or a pin, and the torsion spring 14 may be sleeved on the connecting member 13. The present application does not specifically limit the connecting member 13, as long as the first cover body 11 and the second cover body 12 are rotatably connected.

[0134] In addition, if Figure 1 and Fig.11As shown, the first limiter 3 has a limiter 323. In the locked position, the pressing portion 21 abuts against the limiter 323 along the height direction of the container cover to limit the locking key 2 from being pressed, reduce the risk of the locking key 2 being pressed and rotated, further reduce the risk of the first hook 22 and the second hook 126 being released from the engagement, and improve the anti-accidental touch performance of the cover 1. In the unlocked position, the limiter 323 does not abut against the pressing portion 21 to release the restriction on the rotation of the locking key 2 relative to the cover 1, so that the first cover 11 and the second cover 12 can release the locking cooperation.

[0135] During the locking cooperation between the first cover body 11 and the second cover body 12, the locking key 2 rotates under the squeezing action of the second hook 126, so that the first hook 22 can be engaged with the second hook 126, and at the same time, the first limiter 3 is reset to the locking position, so that the pressing portion 21 abuts against the limiter 323.

[0136] At the same time, if Figure 2 As shown, the inner cover 112 also includes a third protrusion 112b and a hinge hole 112c, and the locking key 2 also includes a fourth protrusion 23 and a first rotating shaft 24. The first rotating shaft 24 can be connected to the hinge hole 112c so that the locking key 2 is rotatably connected to the inner cover 112. When the user presses the pressing portion 21, the third protrusion 112b can abut against the pressing portion 21 along the height direction of the container cover to reduce the risk of pressing the pressing portion 21 and the risk of damage to the internal components of the cover body 1. In addition, the fourth protrusion 23 is arranged on the side of the locking key 2 away from the first hook 22. After the first hook 22 is released from the second hook 126, the fourth protrusion 23 can abut against the outer cover 111 to limit the excessive rotation of the locking key 2, thereby further improving the reliability of the unlocking process of the cover body 1.

[0137] Among them, Figure 2 As shown, the outer cover 111 is provided with a handle 111b and a main body 111c, and an operating space is provided between the handle 111b and the main body 111c. The pressing portion 21 and the operating portion 31 are both located in the operating space. The user needs to extend his hand into the operating space to drive the locking key 2 and the operating portion 31 to move, that is, the handle 111b can be used to protect the pressing portion 21 and the operating portion 31, further reducing the risk of accidental touch and improving the user experience.

[0138] In a possible implementation, Figure 2 , Figure 6 , Figure 8 and Fig.10 As shown, the second cover body 12 is provided with a reset assembly 121. During the movement from the unlocked position to the locked position, the reset assembly 121 is used to drive the second limit member 4 to move along the height direction of the container cover to release the first limit member 3 from the second limit member 4.

[0139] In this embodiment, during the process of moving from the unlocked position to the locked position, that is, during the process of the first cover body 11 closing toward the second cover body 12, the reset assembly 121 can abut against the second limit member 4 to drive the second limit member 4 to move upward along the height direction of the container cover and compress the second elastic member 6, so that the radial projection of the avoidance hole 42 along the container cover can completely cover the first clamping portion 321, thereby releasing the first clamping portion 321 from the second clamping portion 41, and then the first limit member 3 drives the first clamping portion 321 to extend through the avoidance hole 42 under the action of the rebound force of the first elastic member 5, thereby resetting the first limit member 3 to the locked position.

[0140] Therefore, by setting a reset component 121 on the cover body 1, during the movement from the unlocked position to the locked position, the second limit member 4 can automatically move upward along the height direction of the container cover under the action of the reset component 121, thereby improving the reliability of the first limit member 3 and the second limit member 4 being released from the engagement.

[0141] In a possible implementation, Figure 6 and Fig.13 As shown, the reset assembly 121 includes a reset member 121a and a third elastic member 121b, the reset member 121a is movably connected to the second cover 12, along the height direction of the container cover, one end of the third elastic member 121b is connected to the reset member 121a, and the other end is connected to the second cover 12, during the locking and matching process of the first cover 11 and the second cover 12, the second stopper 4 can drive the reset member 121a to move toward the second cover 12 along the height direction of the container cover, and under the action of the rebound force of the third elastic member 121b, the reset member 121a can drive the second stopper 4 to move away from the second cover 12 along the height direction of the container cover, so that the second stopper 4 is released from the first stopper 3. The third member can be sleeved on the reset member 121a.

[0142] During the process of locking and matching the first cover body 11 with the second cover body 12, the angle between the first cover body 11 and the second cover body 12 gradually becomes smaller, so that the second limiting member 4 is abutted against the reset member 121a under the action of the first cover body 11 and drives the reset member 121a to move toward the second cover body 12 along the height direction of the container cover, and then the third elastic member 121b is compressed. When the first cover body 11 moves to the position of locking and matching with the second cover body 12, that is, when the first hook 22 and the second hook 126 are just engaged, the elastic force applied by the third elastic member 121b to the second limiting member 4 is greater than the elastic force applied by the first elastic member 5 to the second limiting member 4, that is, at this time, the rebound force of the third elastic member 121b is greater than the rebound force of the first elastic member 5, and the reset member 121a drives the second limiting member 4 to move away from the second cover body 12 along the height direction of the container cover under the action of the rebound force of the third elastic member 121b, so that the first limiting member 3 and the second limiting member 4 are released from the engagement.

[0143] Therefore, by setting a reset member 121a and a third elastic member 121b on the first cover body 11, during the movement from the unlocked position to the locked position, the second limit member 4 can automatically move upward along the height direction of the container cover under the action of the reset member 121a and the third elastic member 121b, so that the first limit member 3 and the second limit member 4 can be released from the engagement, thereby eliminating the need for the user to manually drive the first limit member 3 to move to the locked position, so that the cover body 1 can be automatically locked, thereby improving the user experience.

[0144] In a possible implementation, Figure 2 and Fig.13 As shown, the first cover body 11 is provided with a first mounting groove 112a, the second stopper 4 has a first bottom wall 43, the first cover body 11 has a second bottom wall 112d, the second stopper 4 is installed inside the first mounting groove 112a, and there is a preset distance between the first bottom wall 43 and the second bottom wall 112d. The reset assembly 121 also includes a reset seat 121c, the reset seat 121c is movably connected to the second cover body 12, the reset seat 121c has a mounting cavity 121d, a part of the reset member 121a is located in the mounting cavity 121d, and can move in the mounting cavity 121d. During the locking and matching process of the first cover body 11 and the second cover body 12, the second bottom wall 112d abuts against the reset seat 121c. Among them, the second bottom wall 112d is the bottom wall of the first mounting groove 112a.

[0145] Specifically, in the locked position, the reset member 121a abuts against the first bottom wall 43 of the second stopper 4, and the third elastic member 121b is compressed. During the opening of the first cover 11, since the second bottom wall 112d of the first cover 11 does not abut against the reset seat 121c, and the reset member 121a does not abut against the first bottom wall 43 of the second stopper 4, the reset assembly 121 moves to the first position along the height direction of the container cover under the action of the rebound force of the third elastic member 121b. During the locking and cooperation process of the first cover body 11 and the second cover body 12, the second bottom wall 112d abuts against the reset seat 121c, so that the reset seat 121c drives the reset member 121a to move toward the second cover body 12 along the height direction of the container cover, and then the reset member 121a abuts against the first bottom wall 43 of the second limiting member 4, and the third elastic member 121b is compressed. Subsequently, when the first cover body 11 moves to the position of locking and cooperation with the second cover body 12, the reset member 121a and the reset seat 121c drive the second limiting member 4 to move away from the second cover body 12 along the height direction of the container cover under the action of the rebound force of the third elastic member 121b, so that the first limiting member 3 and the second limiting member 4 are released from the engagement.

[0146] Therefore, during the locking cooperation between the first cover body 11 and the second cover body 12, the second bottom wall 112d of the first cover body 11 abuts against the reset seat 121c, which can increase the contact area between the first cover body 11 and the reset assembly 121, and is beneficial to improving the stability and reliability of the interaction between the first cover body 11 and the reset assembly 121 to enable the other to move along the height direction of the container cover.

[0147] In a possible implementation, Figure 2 and Figure 6 As shown, the second cover body 12 is provided with a second mounting groove 122, and the second mounting groove 122 is used to install the reset seat 121c. The side wall of the second mounting groove 122 is provided with a limiting hole 122a, and the reset seat 121c is provided with a second protrusion 121e. The second protrusion 121e can slide in the limiting hole 122a along the height direction of the container cover.

[0148] In this embodiment, during the process of locking or unlocking the first cover body 11 and the second cover body 12, the second protrusion 121e can slide in the limiting hole 122a along the height direction of the container cover, reducing the risk of the reset seat 121c detaching from the second mounting groove 122, which is beneficial to improving the structural stability of the cover body 1.

[0149] In a possible implementation, Fig.13 As shown, the reset seat 121c includes a first limiting step 121f, the reset member 121a includes a second limiting step 121g, and the first limiting step 121f abuts against the second limiting step 121g.

[0150] During the process of releasing the locking cooperation between the first cover body 11 and the second cover body 12, the reset member 121a moves under the action of the rebound force of the third elastic member 121b, and abuts against the second limit step 121g through the first limit step 121f, thereby reducing the risk of the reset member 121a moving to the first position and continuing to move, causing it to detach from the reset seat 121c, which is beneficial to further improve the structural stability of the cover body 1.

[0151] The present application also provides a liquid container, such as Figure 1 As shown, the liquid container comprises a container body 7 and a container cover, and the container cover is mounted on the container body 7. The container cover is the container cover in any of the above embodiments.

[0152] When the container cover is used for a liquid container, after the first limit member 3 moves to the unlocking position, the first limit member 3 cooperates with the cover body 1 so that the first limit member 3 can be maintained in the unlocking position avoiding the locking key 2, so that the user does not need to limit the first limit member 3 to the locking position by hand while driving the locking key 2 to move, thereby simplifying the unlocking process of the container cover so that the user can operate it with one hand, thereby improving the user's experience of using the container cover, and further improving the user's experience of using the liquid container.

[0153] In a possible implementation, Figure 1 and Figure 2 As shown, the second cover body 12 may include a drinking opening 123, and the first cover body 11 may include an inner cover 112 and a first sealing member 124 installed on the inner cover 112. When the first cover body 11 and the second cover body 12 are locked and matched, the first sealing member 124 is used to block the drinking opening 123 to prevent liquid from leaking from the drinking opening 123. At the same time, a second sealing member 125 is provided between the container body 7 and the inner cover 112. When pouring liquid from the liquid container, the liquid can flow out through the drinking opening 123, and the second sealing member 125 prevents the liquid from flowing out from between the container body 7 and the inner cover 112.

[0154] In addition, the inner cover 112 can be detachably connected to the second cover body 12 by means of threads.

[0155] The above is only a specific implementation of the embodiment of the present application, but the protection scope of the embodiment of the present application is not limited thereto, and any changes or replacements within the technical scope disclosed in the embodiment of the present application should be included in the protection scope of the embodiment of the present application. Therefore, the protection scope of the embodiment of the present application should be based on the protection scope of the claims.
