[0030] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Although the locking assembly in the specification is described in conjunction with the filter element structure of a water purifier, the present invention is obviously not limited to the application scenario of the filter element of a water purifier. The locking assembly of the present invention can also be applied to a seal having one end of a cylindrical structure, or to a cover at one end of a container, or to the disassembly and installation of strip-shaped battery cells on electric vehicles, etc. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0031] It should be noted that, in the description of the present invention, terms such as "upper", "lower", "horizontal", "vertical", "inside", "outside", "top", and "bottom" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0032] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed to indicate or imply relative importance.

[0033] Specifically, if Figure 1 and Figure 6 As shown, the locking assembly of the present invention includes a fixing base 1, a columnar body 2, a first handle component 3, and a second handle component. The fixing base 1 has an axial cavity (not shown) and a first locking structure and a second locking structure disposed at one end of the axial cavity. The columnar body 2 is located within the axial cavity. Both ends of the first handle component 3 are hingedly connected to one end of the columnar body 2. Support structures that cooperate with the fixing base 1 are respectively provided at both ends of the first handle component 3. The second handle component is hingedly connected to the middle region of the first handle component 3.

[0034] In the locked state, the support structure and the first locking structure cooperate with each other to lock the columnar body 2 in the axial direction of the columnar body 2 in the axial cavity of the fixed seat 1, and one end of the second handle component cooperates with the second locking structure to lock the first handle component 3 on the end face of the columnar body 2.

[0035] When the second handle component is pulled out, one end of the second handle component is unlocked from the second locking structure, and the first handle component 3 is pulled out. The pulled out first handle component 3 then drives the supporting structure to unlock from the first locking structure, and the supporting structure rests on the fixing seat 1 to apply axial pressure so that the columnar body 2 can be moved out of the axial cavity of the fixing seat 1 more effortlessly, thereby making it more convenient to disassemble the columnar body 2, greatly facilitating user operation and improving user experience.

[0036] Preferably, if Figure 1 As shown, the first locking structure and the second locking structure of the present invention are respectively two first slots 11 and a second slot 12 provided on the fixing base 1. The two first slots 11 and the second slot 12 are both distributed along the outer side of the upper end opening of the axial cavity of the fixing base 1, and the two first slots 11 are symmetrically distributed along the radial direction of the upper end opening. The first slots 11 and the second slots 12 are both arranged in an N-shaped structure.

[0037] like Figures 2 to 4 As shown, the first handle member 3 is a semicircular ring structure, and the supporting structure is formed by protrusions 31 formed at both ends of the first handle member 3. A first shaft 32 is formed on the inner side of each end of the first handle member 3. Correspondingly, two first shaft holes 23 are formed at the upper end of the columnar body 2, which are symmetrically distributed along the radial direction. The two first shafts 32 are respectively inserted into the two shaft holes and cooperate with each other to enable the first handle member 3 to rotate to an upright position perpendicular to the end face of the columnar body 2 or a retracted position parallel to the end face of the columnar body 2.

[0038] When the first handle component 3 rotates from the upright state to the retracted state, the two protrusions 31 are rotated and inserted into the two first slots 11 respectively to lock the columnar body 2 in the axial cavity of the fixing base 1 .

[0039] Those skilled in the art will understand that, although the above-described arrangement is that the first handle component 3 is provided with a first shaft rod 32 at both ends and the columnar body 2 is provided with a first shaft hole 23, this is not restrictive. Those skilled in the art may also provide the first shaft hole 23 on the first handle component 3 and the first shaft rod 32 on the columnar body 2. Such adjustments and changes to the specific arrangement of the hinged shaft rod and shaft hole between the first handle component 3 and the columnar body 2 do not deviate from the principle and scope of the present invention, and should be limited within the scope of protection of the present invention.

[0040] like Figure 1 、 Figure 5 as well as Figure 6As shown, the second handle component of the present invention includes a first strip plate 4 and a second strip plate 5, one end of the first strip plate 4 is hingedly connected to the middle area of ​​the first handle component 3, and one end of the first strip plate 4 is also hingedly connected or meshedly connected to one end of the second strip plate 5, and the other end of the second strip plate 5 cooperates with the second slot 12.

[0041] It is understandable that by pulling the first strip plate 4 on the first handle component 3 to rotate, the first strip plate 4 enables the second strip plate 5 and the second slot 12 to cooperate with each other through a hinge or engagement drive to lock or unlock the middle area position of the first handle component 3.

[0042] like Figure 4 and Figure 5 As shown, a first groove structure 33 is provided in the middle area of ​​the first handle component 3 of the present invention, and the first groove structure 33 radially penetrates the first handle component 3. Two second shaft rods 41 are provided on the right end of the first strip plate 4, and two second shaft holes 331 respectively matched with the two second shaft rods 41 are provided in the first groove structure 33. The right end of the second strip plate 5 passes through the first groove structure 33 and cooperates with the second slot 12.

[0043] Those skilled in the art will understand that, although the above-described arrangement is that a second shaft rod 41 is provided at both ends of the second handle component, and a second shaft hole 331 is provided in the first groove structure 33 on the first handle component 3, this is not restrictive. Those skilled in the art may also arrange the second shaft hole 331 on the first strip plate 4, and the second shaft rod 41 in the first groove structure 33 on the first handle component 3. Such adjustments and changes to the specific arrangement of the hinged shaft rod and shaft hole between the first strip plate 4 and the first handle component 3 do not deviate from the principle and scope of the present invention, and should be limited within the scope of protection of the present invention.

[0044] like Figure 5 As shown, in a preferred embodiment of the second handle component, a second slot structure is provided at the right end of the first strip plate 4, and two third shaft rods 51 are provided at the left end of the second strip plate 5. Two third shaft holes 42 are provided within the second slot structure of the first strip plate 4, which cooperate with the two third shaft rods 51. When the first strip plate 4 rotates on the first handle component 3 via the second shaft rods 41 and the second shaft holes 331, the third shaft rods 51 cooperate with the third shaft holes 42 to enable the first strip plate 4 to drive the second strip plate 5 to slide within the first slot structure 33, thereby causing the right end of the second strip plate 5 to extend outside the first slot structure 33 or retract into the first slot structure 33.

[0045] Those skilled in the art will understand that, although the above-described arrangement is that a third shaft rod 51 is provided on the second strip plate 5 and a third shaft hole 42 is provided in the second groove structure of the first strip plate 4, this is not restrictive. Those skilled in the art may also arrange the third shaft hole 42 on the second strip plate 5 and the third shaft rod 51 in the second groove structure of the first strip plate 4. Such adjustments and changes to the specific arrangement of the hinged shaft rod and shaft hole between the first strip plate 4 and the second strip plate 5 do not deviate from the principle and scope of the present invention, and should be limited within the scope of protection of the present invention.

[0046] like Figure 6 As shown, in another preferred embodiment of the second handle component, the right end of the first strip plate 4 is provided with a first tooth shape 44, which is a semicircular tooth shape, and the left end of the second strip plate 5 is provided with a second tooth shape 52, which is a strip-shaped tooth shape. The semicircular tooth shape is coaxial with the second shaft 41.

[0047] When the first strip plate 4 rotates on the first handle component 3 with the help of the second shaft rod 41 and the second shaft hole 331, the first tooth shape 44 and the second tooth shape 52 engage with each other so that the first strip plate 4 drives the second strip plate 5 to slide in the first groove structure 33, thereby causing the right end of the second strip plate 5 to extend out of the first groove structure 33 or retract into the first groove structure 33.

[0048] Both of the above-mentioned two transmission modes between the first strip plate 4 and the second strip plate 5 can enable the first strip plate 4 to drive the second strip plate 5 to cooperate with the second slot 12 to perform unlocking and locking operations on the first handle component 3 .

[0049] Preferably, if Figure 1 and Figure 3 As shown, the end face of the columnar body 2 of the present invention is formed with a first receiving groove 21 for accommodating the first handle component 3. The first receiving groove 21 is a semicircular step structure formed on the edge of the end face of the columnar body 2, and the two first axial holes 23 are both located in the first receiving groove 21. Among them, the two protrusions 31 are located outside the first receiving groove 21. When the first handle component 3 is rotated from the upright state to the retracted state, the first handle component 3 is stored in the first receiving groove 21. The first handle component 3 does not occupy too much space on the end face of the columnar body 2, thereby ensuring the overall aesthetics of the end face of the columnar body 2.

[0050] Preferably, if Figure 1 and Figure 3As shown, the end surface of the columnar body 2 of the present invention is provided with a second receiving groove 22 radially extending therefrom for receiving the first strip plate 4. The length of the second receiving groove 22 is greater than that of the first strip plate 4. This arrangement prevents the first strip plate 4 from occupying excessive space on the end surface of the columnar body 2, thereby ensuring the overall aesthetics of the end surface of the columnar body 2. It also facilitates the removal of the end of the first strip plate 4, making it easier for the user to initiate removal.

[0051] Preferably, if Figure 5 and Figure 6 As shown, the right end of the first strip plate 4 of the present invention is provided with a guide surface 43 , and the guide surface 43 is inclined toward the end surface of the columnar body 2 .

[0052] It is understood that after the first strip plate 4 is accommodated in the second receiving groove 22, the guide surface 43 is inclined toward the bottom surface of the second receiving groove 22 of the columnar body 2. When the first strip plate 4 is pulled, the gap between the guide surface 43 and the bottom surface of the second receiving groove 22 allows the user to easily pry the first strip plate 4 off the end surface of the columnar body 2, saving effort and improving ease of use.

[0053] Finally, the present invention also provides a water purifier, a filter element of the water purifier and a housing for mounting the filter element, wherein the fixing seat 1 is formed on the housing, and the columnar body 2 is formed on the non-water-connecting end of the filter element.

[0054] It can be understood that after the water purifier adopts the above-mentioned locking assembly, when pulling out the filter element, the user only needs to pull out the first strip plate 4 along the axial direction of the filter element. When the first strip plate 4 is unlocked from the second slot 12, the first handle component 3 is brought out. The first handle component 3 applies an axial lever force with the protrusion as the fulcrum to pull the filter element from the shell and when the first handle component 3 is rotated to the axial direction, the protrusion is completely disengaged from the first slot 11, and then the user uses the first handle component 3 to pull the filter element out of the shell more effortlessly. The entire process of pulling out the filter element is labor-saving, convenient and fast.

[0055] It should be noted that, according to actual applications, those skilled in the art may also fix the columnar body 2 as an independent unit at the non-water-connecting end of the filter element.

[0056] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
