[0009] With such a design, the limiting part can be controlled by the locking part of the limiting part. When the limiting part cooperates with different limiting grooves, the relative positions of the moving part and the main body are different, that is, the moving part and the main body can form a retractable structure, which can be adjusted according to needs during use. The relative position of the main body and the moving part can be adjusted in scenes such as storage, packaging, and transportation to put the cover in a retracted state and reduce the space occupied by the cover. When it is necessary to stand up the container cover, the relative position of the main body and the moving part can be adjusted to extend the cover so as to support the container cover.

[0019] Through such a design, when the movable part moves relative to the main body, the limiting part of the limiting part can contact the wall of the limiting groove through the guide surface, and the first guide surface and / or the second guide surface can be used to decompose the force between the limiting part and the limiting groove, so that the limiting part can move in a direction away from the limiting groove and disengage from the limiting groove to unlock the movable part and enable the movable part to move relative to the main body.

[0020] In a possible implementation, at least one of the first guide surface and the second guide surface is a curved surface.

[0021] The use of an arc-shaped guide surface can facilitate the limiting part to extend into and out of the limiting groove, and at the same time can reduce the possibility of sharp corners in the limiting part and the limiting groove, thereby reducing the possibility of wear on the limiting part and the limiting groove, resulting in a decrease in matching accuracy and matching stability.

[0060] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0061] 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.

[0062] In a specific embodiment, the present application is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0063] like Figure 1 As shown, the embodiment of the present application provides a cover head that can be installed on a container cover. The cover head includes a main body 1, a stopper 3 and a moving part 2, wherein the moving part 2 is installed on the main body 1, and the stopper 3 is installed on the moving part 2. Figure 2 As shown, the moving member 2 can move relative to the main body 1 to change the length of the cover head so that the cover head can be extended or retracted. The limiting member 3 is used to limit the relative position between the moving member 2 and the main body 1. Along the length direction of the cover head, the main body 1 is provided with at least two limiting grooves 11 at intervals, such as Figure 3 As shown, the limiting member 3 includes a locking portion 31 and at least one limiting portion 32, and the limiting portion 32 is used to cooperate with the limiting groove 11 to limit the relative position of the moving member 2 and the main body 1. Figure 4As shown, at least a portion of the locking portion 31 can undergo elastic deformation so that the locking portion 31 can move relative to the limiting portion 32, and is used to lock or unlock the limiting portion 32. When the limiting portion 32 is in an unlocked state, the limiting portion 32 can disengage from the limiting groove 11, and the movable part 2 can move relative to the main body 1.

[0064] By such a design, the locking portion 31 of the limiting member 3 can be used to control the limiting portion 32. When the limiting portion 32 cooperates with different limiting grooves 11, the relative positions of the moving member 2 and the main body 1 are different, that is, the moving member 2 and the main body 1 can form a retractable structure. When in use, the relative position of the main body 1 and the moving member 2 can be adjusted according to demand. When adjusting, the locking portion 31 can be elastically deformed by applying an external force to the locking portion 31 to unlock the limiting portion 32. When the moving member 2 moves into place, the external force can be removed, and the locking portion 31 is reset under the action of its own restoring force. In scenes such as storage, packaging, and transportation, the relative position of the main body 1 and the moving member 2 can be adjusted to put the cover in a retracted state to reduce the space occupied by the cover. When the container cover needs to be erected, the relative position of the main body 1 and the moving member 2 can be adjusted to extend the cover so as to support the container cover.

[0065] When the lid of the container lid has a stand function, the lid is large in size, which is very inconvenient during packaging and transportation. Therefore, the lid is usually designed to be detachably connected. During packaging and transportation, the lid is removed from the main body of the pot lid, and the two are packaged and transported independently, and the user assembles it by himself after purchase. Although such a design can facilitate packaging and transportation, the lid needs to be assembled with the help of tools such as screwdrivers, and there is a possibility of misassembly when the user assembles it by himself, which in turn affects the stand function of the container lid, resulting in the container lid being unable to stand on a desktop or the like, or affecting the stability when placed on a desktop or the like.

[0066] like Figure 5 and Figure 6 As shown, the solution provided by the embodiment of the present application, by designing the cover head into a retractable structure, the volume of the cover head can be changed by changing the relative position of the main body 1 and the moving part 2. When packaging and storage are required, the moving part 2 can be retracted to reduce the volume of the cover head for easy packaging and transportation. When support is required, the moving part 2 can be extended relative to the main body 1, thereby changing the volume of the cover head, so that the cover head can be used to support the container cover, so that the container cover can be placed upright on a desktop or the like. Such a design can facilitate the overall packaging and transportation of the container cover, reduce the possibility of users' misinstallation, and thus help improve the quality of the container cover and the stability of the upright placement, which is more in line with actual usage needs.

[0067] like Figure 3 and Figure 4As shown, in a possible embodiment, the locking portion 31 is located on a side of the limiting portion 32 away from the limiting groove 11 and can abut against the limiting member 3, at least a portion of the locking portion 31 can be elastically deformed, and the locking portion 31 can move relative to the limiting portion 32 along the height direction of the cover head. When the locking portion 31 abuts against the limiting portion 32, at least a portion of the limiting portion 32 is located in the limiting groove 11, the locking portion 31 is used to limit the limiting portion 32 from being separated from the limiting groove 11, and the limiting portion 32 is used to limit the relative position between the moving member 2 and the main body 1, thereby reducing the possibility of the moving member 2 moving relative to the main body 1. When the user can press the locking portion 31 to release the abutment between the locking portion 31 and the limiting portion 32, the limiting portion 32 can be disengaged from the limiting groove 11, and the movable member 2 can move relative to the main body 1. When the movable member 2 moves to the desired position, the limiting portion 32 cooperates with the corresponding limiting groove 11. At this time, the locking portion 31 can be released to reset the locking portion 31 and abut against the limiting portion 32 to prevent the limiting portion 32 from disengaging from the limiting groove 11.

[0068] Such a design can facilitate the adjustment of the relative positions of the main body 1 and the moving part 2, so that the user can adjust the cover according to usage requirements.

[0069] like Figure 7 and Figure 8 As shown, in a possible embodiment, the limiting member 3 includes a connecting portion 33, and the connecting portion 33 is connected to the moving member 2. The connection methods include but are not limited to bonding, clamping, welding, threaded connection, etc., and the connecting portion 33 and the moving member 2 can also be provided with connecting holes, respectively, and connected by connecting members such as screws and bolts. The limiting portion 32 includes a connecting section 321 and a limiting section 322, and the connecting section 321 is used to connect the limiting section 322 and the connecting member, and the limiting section 322 is used to cooperate with the limiting groove 11. The connecting section 321 can undergo elastic deformation. When the connecting section 321 undergoes deformation, it can drive the limiting portion 32 to move relative to the limiting groove 11, so that the limiting portion 32 can be separated from or extended into the limiting groove 11.

[0070] When in use, the locking portion 31 can be pressed to release the locking portion 31 from the limiting portion 32, and the limiting portion 322 can be driven to disengage from the limiting groove 11 through the elastic deformation of the connecting segment 321, so that the movable member 2 can move relative to the main body 1, and the restoring force generated by the elastic deformation of the connecting segment 321 can act on the limiting segment 322, so that the limiting segment 322 has a tendency to move in the direction of the limiting groove 11. When the movable member 2 moves to the desired position, the limiting portion 32 can move toward the side close to the limiting groove 11 under the action of the restoring force of the connecting segment 321, thereby extending into the limiting groove 11. At this time, the locking portion 31 can be loosened to reset the locking portion 31 and abut against the side of the limiting segment 322 away from the limiting groove 11, thereby limiting the limiting segment 322 from disengaging from the limiting groove 11.

[0071] With such a design, after the moving member 2 moves to the corresponding position, the limiting section 322 can automatically extend into the limiting groove 11, so that the limiting portion 32 cooperates with the limiting groove 11, which is more convenient in actual use.

[0072] like Figure 7 and Figure 8 As shown, in a possible implementation, the connecting section 321 is provided with a recessed portion 321 a , and the recessed portion 321 a can be provided on a side of the connecting section 321 facing the limiting groove 11 , or on a side of the connecting section 321 away from the limiting groove 11 .

[0073] The recessed portion 321 a is used to reduce the thickness of the connecting section 321 , thereby facilitating deformation of the connecting section 321 , and is beneficial to increasing the elastic deformation capacity of the connecting section 321 , so that the connecting section 321 can drive the limiting section 322 to move relative to the limiting groove 11 .

[0074] In a possible implementation manner, the recessed portion 321 a penetrates the connecting section 321 along the thickness direction of the limiting member 3 .

[0075] Such a design can facilitate the deformation of the connecting section 321, which is beneficial to enhancing the elastic deformation capacity of the connecting section 321. It is also easy to process and more in line with actual usage requirements.

[0076] like Figure 8 and Fig. 9 As shown, in a possible embodiment, the limiting portion 32 has a first guide surface 323, and the first guide surface 323 can be set in the limiting section 322, and / or the limiting groove 11 has a second guide surface 12, and the limiting portion 32 avoids contact with the limiting groove 11 through the first guide surface 323 and / or the second guide surface 12. When the moving member 2 moves relative to the main body 1, the limiting portion 32 and the limiting groove 11 move relative to each other, and the limiting portion 32 moves along the second guide surface 12, and / or the limiting groove 11 moves along the first guide surface 323, so that the limiting portion 32 can be separated from the limiting groove 11. The first guide member and the second guide surface 12 can be inclined surfaces or arc-shaped surfaces, etc.

[0077] Through such a design, when the movable part 2 moves relative to the main body 1, the limiting part 32 of the limiting part 3 can contact the wall surface of the limiting groove 11 through the guide surface, and the first guide surface 323 and / or the second guide surface 12 can be used to decompose the force between the limiting part 32 and the limiting groove 11, so that the limiting part 32 can move in a direction away from the limiting groove 11 and disengage from the limiting groove 11, so as to unlock the movable part 2 and enable the movable part 2 to move relative to the main body 1.

[0078] In a possible implementation manner, at least one of the first guide surface 323 and the second guide surface 12 is an arc-shaped surface.

[0079] The use of an arc-shaped guide surface can facilitate the limiting portion 32 to extend into and out of the limiting groove 11, and at the same time can reduce the possibility of sharp corners appearing on the limiting portion 32 and the limiting groove 11, thereby reducing the possibility of wear on the limiting portion 32 and the limiting groove 11, resulting in a decrease in matching accuracy and matching stability.

[0080] like Fig. 9 As shown, in a possible embodiment, the main body 1 includes a matching groove 13, and the side walls on both sides of the matching groove 13 are respectively provided with at least two limiting grooves 11 in the width direction of the matching groove 13. The limiting member 3 includes two limiting parts 32, and at least one end of the limiting parts 32 is connected by a connecting section 321. The locking part 31 can be located between the limiting parts 32 or detached from the limiting parts 32, and the limiting parts 32 can approach each other or move away from each other. When the limiting parts 32 are matched with the limiting groove 11, the locking part 31 can be located between the limiting parts 32 and abut against the limiting parts 32, which is used to limit the movement of the limiting parts 32 in the direction of approaching each other to detach from the limiting groove 11. When unlocking is required, the locking part 31 can be detached from the limiting parts 32 by pressing or the like, so that the limiting parts 32 can move in the direction of approaching each other, that is, the direction of detaching from the limiting groove 11, thereby detaching from the limiting groove 11.

[0081] Such a design can make the force on the limiting member 3 more balanced when the limiting portion 32 cooperates with the limiting groove 11, thereby reducing the possibility of the limiting member 3 tilting. At the same time, it is beneficial to improve the stability of the cooperation between the limiting portion 32 and the limiting groove 11, which is more in line with actual usage requirements.

[0082] like Fig. 9 As shown, in a possible embodiment, the main body 1 includes a accommodating cavity 14, the accommodating cavity 14 is connected to the matching groove 13, at least part of the movable member 2 is located in the accommodating cavity 14 and can move along the accommodating cavity 14, and at least part of the limiting member 3 is located in the matching groove 13.

[0083] By providing the accommodating chamber 14, the movement of the moving part 2 can be guided to improve the stability of the movement. When the moving part 2 is retracted, the moving part 2 can be stored in the accommodating chamber 14, thereby reducing the overall volume of the cover and better meeting actual usage requirements.

[0084] like Fig.10 As shown, in a possible embodiment, the moving member 2 is provided with an avoidance groove 21, which is located on the side of the moving member 2 facing the limiting member 3, and when the locking portion 31 unlocks the limiting portion 32, at least part of the locking portion 31 extends into the avoidance groove 21.

[0085] Such a design can reduce the possibility of interference between the moving part 2 and the limiting part 3, thereby facilitating use.

[0086] When in use, the user can press the locking portion 31 to release the locking portion 31 from the contact with the limiting portion 32, and at the same time drive the moving member 2 to move along the accommodating cavity 14 relative to the main body 1. When the moving member 2 moves to the desired position, the locking portion 31 is released, and the locking portion 31 automatically returns to the state of contact with the limiting portion 32, limiting the limiting portion 32 from leaving the limiting groove 11. In a possible embodiment, wave-shaped grooves can be provided on opposite sides of the matching groove 13.

[0087] Based on the caps involved in the above embodiments, the embodiment of the present application further provides a container cover, which includes a body and a cap, and the cap is mounted on the body for the convenience of the user to hold. The cap can be the cap involved in any of the above embodiments. Since the cap has the above technical effects, the container cover including the cap also has the corresponding technical effects, which will not be repeated here.

[0088] The main body 1 of the cap is connected to the main body. The main body 1 can be configured as a handle or other structure that is convenient for the user to hold. For ease of use, the main body 1 can be a two-section or multi-section structure with an angle between adjacent parts. For example, the main body 1 can be an "L"-shaped structure.

[0089] The embodiment of the present application provides a cover and a container cover, wherein the cover includes a main body 1, a moving part 2 and a limiting part 3, the moving part 2 is installed on the main body 1 and can move relative to the main body 1, the limiting part 3 is installed on the moving part 2, the main body 1 is provided with at least two limiting grooves 11 at intervals, the limiting part 3 includes a locking part 31 and a limiting part 32, the locking part 31 can move relative to the limiting part 32 for unlocking and locking the limiting part 32, the limiting part 32 can extend into or out of the limiting groove 11, and is used to limit the relative position of the moving part 2 and the main body 1. Through such a design, the cover has a retractable structure, so that the structure of the cover can be adjusted according to actual needs to change the volume of the cover, which is more in line with actual use needs.

[0090] 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.
