[0001] The present application relates to the technical field of fixing structures, and in particular to a fixing structure and a household appliance. Background Art

[0002] There are two types of installation and fixing structures on the market. The first is screw installation and fixing, and the second is clip installation and fixing. The first method cannot be installed with screws in some special locations because the installation tools cannot enter. Although the second method uses the clip method, it can well solve the problem of being unable to fix with screws, but due to the defects of the clip fixing method, it will be difficult to remove the parts once they are installed.

[0003] For example, the Chinese utility model patent with the announcement number CN203608483U discloses a rotating buckle structure, which is used to connect the first associated component and the second associated component, including a groove structure and a buckle structure, wherein the groove structure is arranged at the top of the arc-shaped inner wall of the first associated component, and the buckle structure is arranged at the bottom of the second associated component, and the groove structure is L-shaped, including a longitudinal groove and a transverse groove, the top of the longitudinal groove is provided with an opening, and the middle of the transverse groove is provided with a positioning block, and the buckle structure includes a connecting block and a clamping joint arranged on the outside of the connecting block, and the middle of the clamping joint is provided with a clamping groove that cooperates with the positioning block. Although it is convenient to disassemble the buckle, this technical solution is prone to reverse rotation under the action of external force, causing the first associated component and the second associated component to be separated, affecting the fixing effect. Utility Model Content

[0004] In view of the above technical problems, the purpose of the embodiments of the present application is to provide a fixing structure and a household appliance, which are used to solve the problem that components connected by snap-fitting are easy to separate.

[0005] The embodiment of the present application provides a fixing structure for connecting a first component and a second component, wherein the first component has a receiving cavity, one end of the receiving cavity is connected to one end of the first component to form an assembly opening, and the fixing structure includes:

[0006] a thrust-stop groove, which is provided on the first component and communicates with the accommodating cavity;

[0007] A buckle, which is arranged on the cavity wall of the accommodating cavity;

[0008] A slot provided on the outer wall of the second component;

[0009] a thrust notch, which is provided on the outer wall of the second component;

[0010] Wherein, when the second component is rotated in the assembly opening to be mounted on the first component, the buckle can be inserted into the slot, and the thrust notch is rotated to a position corresponding to the thrust through slot;

[0011] A thrust block, one end of which passes through the thrust through groove and extends into the thrust notch, and the other end of which is located outside the first component to fix the second component on the first component.

[0012] When the second component is inserted into the assembly opening of the first component, the buckle enters the slot and then rotates, so that the second component is installed on the first component. Then the thrust block is inserted into the thrust notch through the thrust through slot to connect the second component to the first component. This prevents the second component from rotating out of the first component, reduces the operating space requirement, and is easy to load and unload.

[0013] As an optional embodiment, the card slot includes a first guide slot and a second guide slot in an inverted L-shaped layout. When the second component moves into the accommodating cavity, the buckle enters the first guide slot from the end of the first guide slot away from the second guide slot, and moves along the first guide slot toward the direction close to the second guide slot. When the second component rotates in the accommodating cavity, the buckle moves along the second guide slot toward the direction away from the first guide slot. The first guide slot is used for guidance when the second component extends into the first component, and the second guide slot is used for guidance when the second component rotates along the accommodating cavity. The opening position thereof reasonably utilizes space and is convenient to use.

[0014] As an optional embodiment, an outwardly protruding mounting portion is provided on the outer wall of the first component, and a convex edge is provided on a side of the mounting portion away from the first component and facing the assembly opening, and part of the convex edge extends in the direction of the thrust through groove and forms a third guide groove. The thrust block can smoothly pass through the thrust through groove through the third guide groove, which is simple to install and avoids the thrust block from being stuck in the thrust through groove.

[0015] As an optional embodiment, the thrust block includes a first block and a second block connected to one side of the first block, and two ends of the second block protrude from two ends of the first block respectively, so that the thrust block forms a T-shaped structure, the first block is used to be inserted into the thrust notch, and the second block is exposed outside the first component. The structure of the first block and the second block does not affect the installation effect and is convenient for users to take and operate.

[0016] As an optional embodiment, a convex strip is provided on one side of the second block facing the convex edge, and the convex strip is used to clamp the second block on the convex edge when the first component is connected to the second component. The first block is inserted into the thrust notch to connect the first component to the second component, and at this time, the thrust block is restricted to the first component through the cooperation of the convex strip and the convex edge to prevent the thrust block from falling.

[0017] As an optional embodiment, the accommodating cavity is a cylindrical structure, the inner wall of the assembly opening is provided with an internal thread, and the second component is provided with an external thread, so that the second component is threadedly connected to the first component. The first component and the second component are also connected by threads, which has low requirements for operating space and can further enhance the connection effect.

[0018] As an optional embodiment, there are multiple buckles and they are distributed circumferentially on the cavity wall of the accommodating cavity, and there are multiple slots and they correspond one to one with the multiple buckles. Through multiple groups of buckles and slots, the first component and the second component are subjected to balanced force during installation, and the connection effect between the first component and the second component is ensured.

[0019] As an optional embodiment, a ring-shaped stopper is provided on the cavity wall of the accommodating cavity to limit the position of the second component extending into the first component. The stopper limits the depth of the second component extending into the first component and can provide support when the second component rotates, ensuring that the buckle smoothly enters the interior of the card slot.

[0020] An embodiment of the present application further provides a household appliance, comprising a first component and a second component, and also comprising the aforementioned fixing structure.

[0021] As an optional embodiment, a groove is provided on the thrust block, and the household appliance further comprises:

[0022] an upper housing capable of being snapped onto the groove;

[0023] The lower shell is arranged on a side of the thrust block away from the groove and is detachably connected to the upper shell so that the thrust block is clamped between the upper shell and the lower shell. The thrust block is clamped by the cooperation of the upper shell and the lower shell, and then the first component, the second component, the upper shell and the lower shell are assembled together, which is simple to operate and has a good connection effect.

[0024] The beneficial effects of the embodiments of the present application are:

[0025] The present application adds a thrust block on the basis of the rotating buckle, which can firmly mount the first component and the second component together, preventing the second component from falling off from the first component after rotating under the action of external force, and has a good fixing effect. Moreover, when the first component and the second component need to be separated, only the thrust block needs to be removed, and then the two components can be separated by rotating, which is simple to operate and convenient to use.

Therefore, the above description should not be considered as limiting, but only as an example of an embodiment. Other modifications within the scope and spirit of the present application will occur to those skilled in the art.

[0036] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0037] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0038] It should also be understood that although the present application has been described with reference to some specific examples, those skilled in the art will be able to readily implement many other equivalent forms of the present application.

[0039] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0040] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present application. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0041] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0042] The embodiment of the present application provides a fixing structure for connecting a first component 1 and a second component 2. The first component 1 has a receiving cavity 11. One end of the receiving cavity 11 passes through one end of the first component 1 to form an assembly opening.

[0043] like Figure 1 As shown, the fixing structure includes a thrust through groove 5, a buckle 6, a clamping groove 7, a thrust notch 8 and a thrust block 9.

[0044] The thrust penetration groove 5 is provided on the first component 1 and communicates with the accommodating cavity 11. The buckle 6 is provided on the cavity wall of the accommodating cavity 11, the slot 7 is provided on the outer wall of the second component 2, and the thrust notch 8 is provided on the outer wall of the second component 2.

[0045] The second component 2 can be extended into the assembly opening and installed on the first component 1 by rotating in the assembly opening. When the second component 2 rotates in the assembly opening, the buckle 6 can be inserted into the slot 7, and the thrust notch 8 rotates to a position corresponding to the thrust through slot 5.

[0046] One end of the thrust block 9 passes through the thrust through groove 5 and extends into the thrust notch 8 , and the other end is located outside the first component 1 to fix the second component 2 on the first component 1 .

[0047] When the second component 2 is inserted into the assembly opening of the first component 1, the buckle 6 enters the slot 7 and then rotates, so that the second component 2 is installed on the first component 1. Then the thrust block 9 is inserted into the thrust notch 8 through the thrust penetration slot 5, so that the second component 2 is connected to the first component 1. This prevents the second component 2 from escaping from the first component 1 when rotating in the reverse direction. The fixing structure of this embodiment has low requirements for operating space and is easy to load and unload.

[0048] As an optional embodiment, Figure 1 As shown, the slot 7 includes a first guide slot 71 and a second guide slot 72 in an inverted L-shaped layout. When the second component 2 moves into the accommodating cavity 11, the buckle 6 enters the first guide slot 71 from the end of the first guide slot 71 away from the second guide slot 72, and moves along the first guide slot 71 toward the direction close to the second guide slot 72. When the second component 2 rotates in the accommodating cavity 11, the buckle 6 moves along the second guide slot 72 in the direction away from the first guide slot 71.

[0049] Specifically, when the second component 2 enters the first component 1 through the assembly opening, the buckle 6 moves along the first guide groove 71. When the second component 2 rotates in the accommodating cavity 11, the buckle 6 rotates along the second guide groove 72. That is, the first guide groove 71 is used for guidance when the second component 2 extends into the first component 1, and the second guide groove 72 is used for guidance when the second component 2 rotates along the accommodating cavity 11. The positions of the second guide grooves 71 reasonably utilize space and are convenient to use.

[0050] As an optional embodiment, Figure 1 As shown, the outer wall of the first component 1 is provided with a mounting portion 13 protruding outward, and the mounting portion 13 is provided with a convex edge 14 on a side away from the first component 1 and facing the assembly opening, and part of the convex edge 14 extends in the direction of the thrust through groove 5 and forms a third guide groove 15. The thrust block 9 can smoothly pass through the thrust through groove 5 through the third guide groove 15, ensuring that one end of the thrust block 9 is inserted into the thrust notch 8, which is simple to install and avoids the situation where the thrust block 9 is stuck in the thrust through groove 5.

[0051] As an optional embodiment, Figure 3 As shown, the thrust block 9 includes a first block 91 and a second block 93 connected to one side of the first block 91, and the two ends of the second block 93 protrude from the two ends of the first block 91, so that the thrust block 9 forms an approximately T-shaped structure, the first block 91 is used to be inserted into the thrust notch 8, and the second block 93 is exposed outside the first component 1. The structure of the first block 91 and the second block 93 does not affect the installation effect, and is also convenient for users to take and operate.

[0052] As an optional embodiment, Figure 3 As shown, a convex strip 94 is provided on one side of the second block 93 facing the convex edge 14, and the convex strip 94 is used to clamp the second block 93 on the convex edge 14 when the first component 1 is connected to the second component 2. The first block 91 is inserted into the thrust notch 8 to connect the first component 1 to the second component 2, and at this time, the thrust block 9 is restricted to the first component 1 through the cooperation of the convex strip 94 and the convex edge 14 to prevent the thrust block 9 from falling off.

[0053] As an optional embodiment, Figure 1 As shown, the accommodating cavity 11 is a cylindrical structure, the inner wall of the assembly port is provided with an internal thread, and the second component 2 is provided with an external thread, so that the second component 2 is threadedly connected to the first component 1. The first component 1 and the second component 2 are also connected by threads, which has low requirements for operating space and can further enhance the connection effect.

[0054] As an optional embodiment, Figure 1 As shown, there are multiple buckles 6 and they are circumferentially distributed on the cavity wall of the accommodating cavity 11, and there are multiple slots 7 and they correspond one to one with the multiple buckles 6. Through multiple groups of buckles 6 and slots 7, the first component 1 and the second component 2 are subjected to balanced forces during installation, and the connection effect between the first component 1 and the second component 2 is ensured.

[0055] As an optional embodiment, Figure 1 As shown, an annular stop platform 12 is provided on the cavity wall of the accommodating cavity 11, which is used to limit the position of the second component 2 extending into the first component 1. The stop platform 12 limits the depth of the second component 2 extending into the first component 1, and can provide support when the second component 2 rotates, ensuring that the buckle 6 smoothly enters the interior of the card slot 7.

[0056] In addition, installation marks may be provided on the first component 1 and the second component 2 respectively. After the installation marks of the two components are aligned, the buckle 6 can smoothly enter the slot 7, making it convenient to install the second component 2 on the first component 1.

[0057] When the first component 1 and the second component 2 need to be installed and fixed, the user extends the second component 2 into the accommodating cavity 11 of the first component 1 through the assembly port. At this time, it is necessary to ensure that the buckle 6 can smoothly enter the first guide groove 71. When the entry of the second component 2 is blocked, it means that the second component 2 is inserted into place, and then the second component 2 is rotated along the first direction (which can be clockwise or counterclockwise) to make the buckle 6 move along the second guide groove 72, and at the same time, the external thread of the second component 2 cooperates with the internal thread of the first component 1 to achieve the connection between the first component 1 and the second component 2. In addition, after the second component 2 is rotated, the thrust notch 8 can be rotated to the position corresponding to the thrust through groove 5, and the user moves the thrust block 9 along the third guide groove 15 so that the thrust block 9 passes through the thrust through groove 5 and then inserts into the thrust notch 8, thereby preventing the second component 2 from being unscrewed from the first component 1 and causing it to fall off, thereby achieving the effect of fixing the first component 1 and the second component 2. After installation, the convex strip 94 of the thrust block 9 can be stuck on the convex edge 14 of the first component 1, thereby preventing the thrust block 9 from falling off.

[0058] When the second component 2 needs to be removed, it is only necessary to first remove the thrust block 9, then rotate the second component 2 in the opposite direction, and then remove the second component 2 in the direction away from the assembly opening. This fixing method is simple and firm, and there is no need to worry about damaging the installed parts.

[0059] The present application also provides a household appliance, such as Figure 4-Figure 6 As shown, the household appliance includes a first component 1 and a second component 2, and also includes the aforementioned fixing structure. The household appliance may be a tabletop water purifier, the first component 1 is a lower shell of a display screen, and the second component 2 is an upper shell of a display screen.

[0060] As an optional embodiment, a groove 92 is formed on the thrust block 9 , and the household appliance further comprises an upper housing 3 and a lower housing 4 . The groove 92 is formed on the first block 91 .

[0061] The upper shell 3 can be snapped onto the groove 92 , and the lower shell 4 is arranged on the side of the thrust block 9 away from the groove 92 and is detachably connected to the upper shell 3 so that the thrust block 9 is clamped between the upper shell 3 and the lower shell 4 .

[0062] Therefore, the present invention can ensure the effect of fixing the parts and facilitate disassembly. In particular, it can meet the installation and fixing requirements of a display screen and a housing, that is, it can facilitate the disassembly and maintenance of the display screen and prevent the display screen from falling off, and is suitable for occasions such as desktop water purifiers that require disassembly and maintenance of the display screen.

[0063] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
