It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0051] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0052] Existing dielectric filters usually include a cavity, a resonant rod arranged in the cavity, a cover plate covering the cavity, and a spring. The cover plate is provided with a spring slot corresponding to the resonant rod. The spring is limitedly installed in the spring slot. The spring is used to elastically squeeze the bottom of the spring slot through its own elasticity, so that the bottom of the spring slot is deformed and tightly abuts the resonant rod, thereby pressing the resonant rod between the cover plate and the cavity.

[0053] During the assembly process of installing the spring clip in the spring clip slot, the industry typically uses a sleeve tool to manually press the spring clip and rotate it to retain it in the slot. However, this method is time-consuming and labor-intensive, resulting in low installation efficiency.

[0054] Therefore, the embodiment of the present application provides a spring clip installation mechanism, which aims to solve the problem of low installation efficiency of spring clips in existing dielectric filters.

[0055] The following describes the specific implementation of this application in detail with reference to specific embodiments:

[0056] See also Figure 1 、 Figure 2 、 Figure 3 Some embodiments of the present application provide a spring clip installation mechanism, which is used to positionally install the spring clip 20' in the spring clip slot 11' of the filter cover 10'. Figure 1 、 Figure 2 As shown, in some embodiments, the spring piece 20' is provided with a limiting portion 21' on its circumferential side, and the spring piece slot 11' includes a first sub-slot 111' and a second sub-slot 112' arranged in sequence from the slot mouth to the bottom of the spring piece slot 11', the first sub-slot 111' and the second sub-slot 112' are connected, and the shape of the first sub-slot 111' corresponds to the shape of the spring piece 20', that is, the first sub-slot 111' has a limiting slot area 1111' arranged corresponding to the limiting portion 21' of the spring piece 20', the size of the first sub-slot 111' is equal to or slightly larger than the size of the spring piece 20', the first sub-slot 111' is used for the spring piece 20' to be placed therein and for the spring piece 20' to enter and exit the second sub-slot 112' through it, and the second sub-slot 112' is used for limiting the installation of the spring piece 20' when the spring piece 20' is placed therein and the posture is staggered with the first sub-slot 111'.

[0057] Please also refer to Figure 4 、 Figure 5 The spring clip installation mechanism includes a base plate 10, a mounting fixture 20, and a drive assembly 30. The base plate 10 is provided with a through rotation hole 11; the mounting fixture 20 includes a rotating portion 21 and a loading portion 22 connected in sequence. The rotating portion 21 is rotatably mounted in the rotation hole 11, and the loading portion 22 is used to limit and press the spring clip 20'. The drive assembly 30 is installed on the side of the base plate 10 away from the loading portion 22. The drive assembly 30 is connected to the rotating portion 21 of the mounting fixture 20 and is used to drive the mounting fixture 20 to rotate.

[0058] It should be noted that the base plate 10 is used to reliably support the mounting fixture 20 and the drive assembly 30, and to stabilize the relative position, relative state, and connection relationship between the mounting fixture 20 and the drive assembly 30. The base plate 10 is provided with at least one rotation hole 11, which is provided through the thickness of the base plate 10. The number of rotation holes 11 provided corresponds to the number of mounting fixtures 20 provided, and the rotation holes 11 are used to allow the mounting fixtures 20 to be rotatably installed therein.

[0059] It should also be noted that the mounting fixture 20 includes a rotating portion 21 and a loading portion 22 connected in sequence. The connection between the rotating portion 21 and the loading portion 22 can be integral or separate, and this is not limited in this embodiment. The rotating portion 21 is rotatably mounted in the rotating hole 11. The loading portion 22, facing away from the rotating portion 21, is configured to engage with the spring clip 20' in a limited position and, when the spring clip 20' is positioned in the first sub-slot 111' of the spring clip slot 11', press the spring clip 20' against the first sub-slot 111' to move the spring clip 20' from the first sub-slot 112'. There is at least one mounting fixture 20, and optionally, there are multiple mounting fixtures 20. This arrangement facilitates simultaneous installation of multiple spring clips 20' using multiple mounting fixtures 20 when the filter has multiple resonant rods, multiple spring clip slots 11' corresponding to the multiple resonant rods, and multiple spring clips 20'. This improves installation efficiency. Preferably, the number of installation tools 20 is set to correspond to the number of spring clip slots 11' of the filter cover 10', that is, the number of installation tools 20 is set to correspond to the number of spring clips 20' to be installed in a limited position. Such a setting can facilitate the spring clip installation mechanism to complete the limited installation operation of each spring clip 20' required for the filter cover 10' through each installation tool 20, thereby greatly improving the installation efficiency.

[0060] It should also be noted that the drive assembly 30 is mounted on the side of the base plate 10 facing away from the loading portion 22. This arrangement facilitates the connection between the drive assembly 30 and the mounting fixture 20 and substantially prevents interference between the drive assembly 30 and the filter cover 10', as well as the engagement between the loading portion 22 and the spring 20'. The drive assembly 30 is connected to the rotating portion 21 of at least one mounting fixture 20. The drive assembly 30 is used to drive the mounting fixture 20 to rotate, and can even precisely control the rotation angle of the mounting fixture 20, thereby improving installation efficiency and accuracy.

[0061] Based on the above arrangement, when the spring clip 20' has been inserted into the first sub-slot 111' of the spring clip slot 11' of the filter cover 10' but has not been limitedly installed in the second sub-slot 112', the spring clip installation mechanism can be placed on the side of the filter cover 10' where the spring clip slot 11' is provided, and the loading part 22 of the installation device 20 is aligned with the spring clip 20' and limitedly matched. Based on this, the spring clip installation mechanism can first press the spring clip 20' through the loading part 22 of the installation device 20 to make the spring clip 20' enter the second sub-slot 112' from the first sub-slot 111'. Subsequently, the spring clip installation mechanism can drive the installation device 20 to rotate through the driving component 30, so as to drive the spring clip 20' that is limited by it to rotate synchronously through the loading part 22, until the posture of the spring clip 20' in the second slot 112' is rotated to a state staggered with the first slot 111', so that the spring clip 20' can be conveniently and quickly installed in the second slot 112' of the spring clip slot 11'.

[0062] In summary, the spring clip installation mechanism provided in the embodiment of the present application can, when the spring clip 20' has been placed in the spring clip slot 11' of the filter cover 10' but has not been restrainedly installed in the spring clip slot 11', use the loading portion 22 of the installation device 20 to engage with the spring clip 20' in a corresponding restraining manner, and use the loading portion 22 of the installation device 20 to press the spring clip 20' so that the spring clip 20' is deeply inserted into the spring clip slot 11'; then, the installation device 20 is driven to rotate by the driving assembly 30, so that the spring clip 20', which is restrained and engaged with it, is driven to rotate synchronously via the loading portion 22, so that the spring clip 20' is restrainedly installed in the spring clip slot 11'. As a result, the spring clip installation mechanism provided in the embodiment of the present application can conveniently, quickly, and save time and effort to achieve restrained installation of the spring clip 20' in the spring clip slot 11', thereby effectively improving the installation efficiency of the spring clip 20' and effectively improving the assembly efficiency of the filter. Furthermore, the shrapnel installation mechanism can increase the number of shrapnel 20' that can be installed in a limited position at the same time by increasing the number of installation tools 20, thereby further improving the installation efficiency of the shrapnel 20' and further improving the assembly efficiency of the filter. Furthermore, the shrapnel installation mechanism can precisely control the rotation angle of the installation tool 20 via the drive assembly 30, reducing the risk of insufficient or excessive rotation of the shrapnel 20', thereby reducing the risk of the shrapnel 20' being loosened from the shrapnel slot 11' due to incomplete rotation, thereby improving the installation accuracy and reliability of the shrapnel 20'.

[0063] See also Figure 4 、 Figure 5 In some embodiments of the present application, the driving assembly 30 includes a movable part 31, a driving part 32 and a transmission part 33. The movable part 31 extends along the first direction x, the driving part 32 is used to drive the movable part 31 to move back and forth along the first direction x, and the transmission part 33 is connected between the movable part 31 and the rotating part 21. The transmission part 33 is used to drive the installation device 20 to rotate when the movable part 31 moves back and forth along the first direction x.

[0064] It should be noted that the movable part 31 is extended along the first direction x, and the movable part 31 has the freedom to move back and forth along the first direction x. The driving part 32 is connected to the movable part 31, and the driving part 32 is used to drive the movable part 31 to move back and forth along the first direction x. The driving part 32 can be manually driven or electrically driven, and this embodiment does not limit this. The number of transmission parts 33 is set to correspond to the number of installation devices 20, that is, the transmission parts 33 and the installation devices 20 are set in a one-to-one correspondence. The transmission part 33 is connected to the movable part 31 and the rotating part 21 for transmission, and this embodiment does not limit the specific structure of the transmission part 33. When the movable part 31 moves back and forth along the first direction x, the transmission part 33 can be transmitted between the movable part 31 and the rotating part 21 to drive the installation device 20 to rotate.

[0065] Please also refer to Figure 2By adopting the above solution, the drive assembly 30 can drive the movable member 31 to reciprocate along the first direction x via the drive member 32, and the transmission member 33 is connected between the movable member 31 and the rotating portion 21 to convert the movement of the movable member 31 into rotation of the installation device 20, thereby driving the installation device 20 to rotate. As a result, the drive assembly 30 can conveniently, quickly, and smoothly drive the installation device 20 to rotate with a simplified and reliable structure, thereby facilitating the rotation of the spring clip 20' engaged with the loading portion 22 of the installation device 20, facilitating the limited installation of the spring clip 20' in the spring clip slot 11', and improving the installation efficiency of the spring clip 20'. In addition, the drive component 30 can also accurately control the rotation angle of the installation device 20 based on the relationship between the "moving stroke of the movable part 31 along the first direction x", the "transmission relationship of the transmission part 33" and the "rotation angle of the installation device 20". By accurately controlling the "moving stroke of the movable part 31 along the first direction x", or accurately designing the "transmission relationship of the transmission part 33", the risk of insufficient or excessive rotation angle of the spring clip 20' can be reduced, and the risk of the spring clip 20' being easily loosened from the spring clip slot 11' due to inadequate rotation can be reduced, thereby improving the installation accuracy and installation reliability of the spring clip 20'.

[0066] Of course, in other possible implementations, the drive assembly 30 may adopt other structural designs to drive the installation device 20 to rotate, such as a design combining a rotary drive and multiple gears, which is not limited in this embodiment.

[0067] See also Figure 4 、 Figure 5 In some embodiments of the present application, there are multiple installation devices 20, multiple transmission members 33, and one movable member 31. Each transmission member 33 is transmission-connected between the movable member 31 and the rotating part 21 of each installation device 20.

[0068] It should be noted that there are multiple mounting devices 20, and the number of transmission members 33 is equal to the number of mounting devices 20, that is, the transmission members 33 are arranged in a one-to-one correspondence with the mounting devices 20. Each transmission member 33 is respectively connected to the rotating portion 21 of the corresponding mounting device 20.

[0069] The transmission members 33 and the installation devices 20 may be distributed on opposite sides of the movable member 31 or both disposed on one side of the movable member 31 , and may be specifically designed according to the layout of the spring slots 11 ′ of the filter cover 10 ′.

[0070] By adopting the above scheme, a movable part 31, multiple transmission parts 33 and multiple installation devices 20 can be designed so that each transmission part 33 can be used to transmit the connection between the same movable part 31 and the rotating part 21 of each installation device 20. Based on this, the movement of a movable part 31 can drive the movement of each transmission part 33, thereby achieving the rotation of each installation device 20 connected to each transmission part 33. Therefore, on the one hand, the number of installation devices 20 can be increased to increase the number of spring clips 20' that can be limitedly installed by the spring clip installation mechanism at the same time, thereby improving the installation efficiency of the spring clip 20' and the assembly efficiency of the filter; on the other hand, the number of movable parts 31 can be effectively reduced, the number of parts of the drive assembly 30 can be effectively reduced, the structure of the drive assembly 30 can be effectively simplified, and the cost of the drive assembly 30 can be effectively reduced; on the other hand, the difficulty of transmission design between the movable part 31 and the transmission part 33 can be effectively reduced, and the structural reliability and transmission reliability of the drive assembly 30 can be improved.

[0071] See also Figure 4 、 Figure 5 In some embodiments of the present application, the transmission member 33 is a connecting rod structure, one end of the transmission member 33 is sleeved on the outer periphery of the rotating part 21 and rotates synchronously with the rotating part 21, and the other end of the transmission member 33 can rotate around the rotation axis of the rotating part 21 driven by the movable member 31.

[0072] It should be noted that, in this embodiment, the transmission member 33 is a connecting rod structure that is transmission-connected between the movable member 31 and the rotating portion 21. One end of the transmission member 33 is sleeved on the outer periphery of the portion of the rotating portion 21 that protrudes from the base plate 10, and rotates synchronously with the rotating portion 21. Based on this, the rotating portion 21 and the end of the transmission member 33 connected to the rotating portion 21 will be fixed relative to the plane position of the base plate 10, and can rotate synchronously around the same axis (basically corresponding to the central axis of the rotating hole 11). Among them, this embodiment does not limit the specific implementation method of "the end of the transmission member 33 connected to the rotating portion 21 rotates synchronously with the rotating portion 21". For example, components such as flat keys and screws can be used to circumferentially limit the end of the transmission member 33 and the rotating portion 21 to each other so as to maintain synchronous rotation of the two.

[0073] The other end of the transmission member 33 can be connected to the movable member 31, for example, it can be swingably connected or slidably connected to the movable member 31. Since the rotating part 21 and the end of the transmission member 33 connected to the rotating part 21 are fixed relative to the plane position of the substrate 10, when the driving member 32 drives the movable part 31 to move back and forth along the first direction x, the end of the transmission member 33 connected to the movable part 31 can be driven by the movable part 31 to rotate synchronously around the rotation axis of the rotating part 21 (basically corresponding to the central axis of the rotating hole 11). As the end of the transmission member 33 connected to the movable part 31 rotates, the transmission member 33 as a whole rotates around the rotation axis of the rotating part 21. Since the transmission member 33 is sleeved on one end of the rotating part 21 and keeps rotating synchronously with the rotating part 21, when the transmission member 33 as a whole rotates around the rotation axis of the rotating part 21, the rotating part 21 can be driven to rotate synchronously via the end of the transmission member 33 connected to the rotating part 21, thereby driving the installation device 20 to rotate.

[0074] Of course, the other end of the transmission member 33 may not be connected to the movable member 31, but the movable member 31 may be provided with a paddle or other structure, so that when the driving member 32 drives the movable member 31 to move back and forth along the first direction x, the movable member 31 can drive (for example, push) the other end of the transmission member 33 to rotate around the rotation axis of the rotating part 21 via the paddle or other structure, so that the transmission member 33 as a whole can rotate around the rotation axis of the rotating part 21, so that the end of the transmission member 33 connected to the rotating part 21 can drive the rotating part 21 to rotate synchronously, thereby realizing driving the installation device 20 to rotate.

[0075] Please also refer to Figure 2 By adopting the above solution, the transmission member 33 can be designed as a connecting rod structure. By connecting one end of the transmission member 33 to the rotating part 21 and maintaining synchronous rotation, and by enabling the other end to rotate around the rotation axis of the rotating part 21 under the drive of the movable member 31, a transmission connection between the movable member 31 and the rotating part 21 is reliably achieved, thereby reliably driving the installation device 20 to rotate. Specifically, when the driving member 32 drives the movable member 31 to reciprocate along the first direction x, the end of the transmission member 33 away from the rotating part 21 can rotate around the rotation axis of the rotating part 21 under the drive of the movable member 31, causing the transmission member 33 to rotate around the rotation axis of the rotating part 21 as a whole. As a result, the end of the transmission member 33 connected to the rotating part 21 drives the rotating part 21 to rotate synchronously, thereby driving the installation device 20 to rotate.

[0076] Thus, the transmission member 33 can be reliably connected between the movable member 31 and the rotating portion 21 using a simplified and reliable connecting rod structure, thereby conveniently, quickly, and smoothly driving the installation device 20 to rotate. This improves the structural reliability and performance of the drive assembly 30 and facilitates the installation efficiency of the spring piece 20'. Furthermore, there is a certain correlation between the "movement stroke of the movable member 31 along the first direction x," the "rotation angle of the transmission member 33 as a whole about the rotation axis of the rotating portion 21," the "rotation angle of the end portion of the transmission member 33 connected to the rotating portion 21," and the "rotation angle of the installation device 20." Therefore, the above-described solution facilitates accurate determination of the relationship between the "movement stroke of the movable member 31 along the first direction x," the "rotation angle of the transmission member 33 as a whole about the rotation axis of the rotating portion 21," the "rotation angle of the end portion of the transmission member 33 connected to the rotating portion 21," and the "rotation angle of the installation device 20." This facilitates precise control of the rotation angle of the installation device 20 and improves the installation accuracy and reliability of the spring piece 20'.

[0077] See also Figure 4 、 Figure 5 、 Figure 6 In some embodiments of the present application, a first limiting groove 211 is provided in a ring shape on the outer periphery of the rotating part 21, and the spring installation mechanism also includes a first limiting ring 40 installed in the first limiting groove 211, and the first limiting ring 40 is limited to the side of the transmission member 33 away from the substrate 10.

[0078] It should be noted that the outer periphery of the rotating portion 21 is provided with a first retaining groove 211. The first retaining groove 211 is an annular groove and extends along the circumference of the rotating portion 21. When one end of the transmission member 33, which is a connecting rod structure, is sleeved onto the outer periphery of the rotating portion 21, the first retaining groove 211 is located at the portion of the rotating portion 21 that extends through the transmission member 33. In other words, the transmission member 33 is located between the first retaining groove 211 and the base plate 10.

[0079] It should also be noted that the first limiting ring 40 is in the shape of an open ring or a closed ring. When one end of the transmission member 33 is sleeved on the outer periphery of the rotating part 21 and installed in place, the first limiting ring 40 can be installed in the first limiting groove 211, so that the first limiting ring 40 can limit the side of the transmission member 33 away from the substrate 10, thereby limiting the end of the transmission member 33 between the first limiting ring 40 and the substrate 10, thereby reliably limiting the end of the transmission member 33 from escaping from the rotating part 21, and reliably improving the position stability, connection stability and connection reliability between the end of the transmission member 33 and the rotating part 21. Among them, the first limiting ring 40 can be fixedly installed or detachably installed in the first limiting groove 211, and this embodiment does not impose any restrictions on this.

[0080] The first limiting ring 40 is preferably in the shape of an open ring, for example, Figure 6 As shown, the first limiting ring 40 includes a first ring body 41 in the form of an open ring, and a first limiting block 42 provided on the inner ring of the first limiting ring 41 and protruding inward. The first ring body 41 is configured to be sleeved onto the outer circumference of the rotating portion 21, and the first limiting block 42 is configured to be inserted into the first limiting groove 211 for limiting position. This arrangement facilitates installation of the first limiting ring 40 in the first limiting groove 211, thereby improving the convenience and efficiency of assembly between the first limiting ring 40 and the first limiting groove 211.

[0081] By adopting the above-mentioned scheme, on the basis that one end of the transmission member 33 of the connecting rod structure is sleeved on the outer periphery of the rotating part 21 and keeps synchronous rotation with the rotating part 21, the first limiting ring 40 is installed in the first limiting groove 211 to limit the side of the transmission member 33 away from the substrate 10 through the first limiting ring 40, so as to limit the end of the transmission member 33 between the first limiting ring 40 and the substrate 10, thereby reliably limiting the end of the transmission member 33 from escaping from the rotating part 21, and reliably improving the position stability, connection stability and connection reliability between the end of the transmission member 33 and the rotating part 21. Therefore, the rotation synchronization and rotation smoothness of the end of the transmission member 33 and the rotating part 21 can be effectively guaranteed and improved.

[0082] See also Figure 4 、 Figure 5 、 Figure 6 In some embodiments of the present application, a sliding portion 331 is provided at one end of the transmission member 33, the movable member 31 is provided with a connecting block 311, the connecting block 311 is provided with a slide groove 3111, the slide groove 3111 is arranged to pass through along the depth direction of the groove, and the sliding portion 331 is slidably connected in the slide groove 3111.

[0083] It should be noted that a sliding portion 331 is protruded from the end of the transmission member 33 away from the rotating portion 21 toward the side close to the connecting block 311 . The sliding portion 331 may be, but is not limited to, columnar, for example, cylindrical.

[0084] Correspondingly, a connecting block 311 is provided on the side of the movable member 31 facing the transmission member 33, and the connecting block 311 is used to connect to the transmission member 33. A sliding groove 3111 is provided on the side of the connecting block 311 facing the base plate 10. The extending direction of the sliding groove 3111 intersects the first direction x, and the sliding groove 3111 is provided through the sliding groove 3111 in the groove depth direction.

[0085] The sliding portion 331 is slidably connected to the sliding groove 3111. The sliding groove 3111 is used to provide a movable space for the sliding portion 331 and to constrain the movable path and movable stroke of the sliding portion 331.

[0086] Based on this, by adopting the above solution, one end of the transmission member 33 having a connecting rod structure can be movably connected to the movable member 31 by inserting the sliding portion 331 and slidingly connecting it in the sliding groove 3111. The sliding groove 3111 provides a movable space for the sliding portion 331, and the sliding groove 3111 constrains the movable path and movable stroke of the sliding portion 331. Based on this, on the one hand, during the reciprocating movement of the movable member 31 along the first direction x, the end of the transmission member 33 movably connected to the movable member 31 can rotate around the rotation axis of the rotating portion 21 as the movable member 31 moves along the first direction x, and the sliding portion 331 can adaptively slide in the sliding groove 3111, so that the transmission member 33 as a whole can flexibly rotate around the rotation axis of the rotating portion 21, reducing the risk of interference and jamming, and allowing the end of the transmission member 33 connected to the rotating portion 21 to smoothly and reliably drive the installation device 20 to rotate. On the one hand, because the slide groove 3111 can constrain the movable path and movable stroke of the sliding portion 331, the cooperation between the slide groove 3111 and the sliding portion 331 can, to a certain extent, constrain "the stroke of the end portion of the transmission member 33 movably connected to the movable member 31," "the angle of rotation of the transmission member 33 as a whole about the rotation axis of the rotating portion 21," "the rotation angle of the end portion of the transmission member 33 connected to the rotating portion 21," and "the rotation angle of the installation device 20," thereby facilitating precise control of the rotation angle of the installation device 20 and improving the installation accuracy and reliability of the spring piece 20'. On the other hand, because the slide groove 3111 can constrain the movable path and movable stroke of the sliding portion 331, the slide groove 3111 can provide a certain limiting and positioning effect on the initial position and extreme position of the sliding portion 331, thereby positioning the transmission member 33 to a certain extent in its initial state and extreme state when rotating about the rotation axis of the rotating portion 21, thereby facilitating the transmission member 33 to return to its initial state, that is, facilitating the state reset of the transmission member 33 and the installation device 20.

[0087] See also Figure 4 、 Figure 5 、 Figure 6 In some embodiments of the present application, the size of the sliding portion 331 in the groove width direction of the sliding groove 3111 is adapted to the groove width of the sliding groove 3111 .

[0088] By adopting the above scheme, the size of the sliding part 331 in the groove width direction of the slide groove 3111 can be adapted to the groove width of the slide groove 3111 to ensure that the sliding part 331 can continuously abut against the groove wall of the slide groove 3111. Based on this, it can be ensured that the groove wall of the slide groove 3111 can form a push against the sliding part 331, so that during the reciprocating movement of the movable part 31 along the first direction x, it can be ensured that the groove wall of the slide groove 3111 can apply a force to the sliding part 331 and the transmission part 33 to facilitate the rotation of the transmission part 33.

[0089] See also Figure 4、 Figure 5 、 Figure 6 In some embodiments of the present application, a second limiting groove 3311 is provided in a ring shape on the outer periphery of the sliding portion 331, and the spring installation mechanism also includes a second limiting ring 50 installed in the second limiting groove 3311, and the second limiting ring 50 is limited to the side of the connecting block 311 away from the substrate 10.

[0090] It should be noted that a second limiting groove 3311 is provided on the outer periphery of the sliding portion 331. The second limiting groove 3311 extends along the circumference of the sliding portion 331 and is an annular groove. When the sliding portion 331 is inserted into and slidably connected to the chute 3111, the second limiting groove 3311 is located on the portion of the sliding portion 331 that extends out of the chute 3111. In other words, the connecting block 311 is located between the second limiting groove 3311 and the main body of the transmission member 33.

[0091] It should also be noted that the second limiting ring 50 is in the shape of an open ring or a closed ring. When the sliding portion 331 is inserted into and slidably connected to the slide groove 3111, the second limiting ring 50 can be installed in the second limiting groove 3311. The second limiting ring 50 is limited to the side of the connecting block 311 facing away from the substrate 10, thereby reliably preventing the sliding portion 331 from escaping the slide groove 3111, thereby reliably improving the connection stability and reliability between the sliding portion 331 of the transmission member 33 and the connecting block 311. The second limiting ring 50 can be fixedly installed or detachably installed in the second limiting groove 3311, which is not limited in this embodiment.

[0092] The second limiting ring 50 is preferably in the shape of an open ring, for example, Figure 6 As shown, the second limiting ring 50 includes an open-ring second ring body 51 and a second limiting block 52 provided on the inner ring of the second limiting ring 51 and protruding inward. The second ring body 51 is configured to be sleeved on the outer periphery of the sliding portion 331, and the second limiting block 52 is configured to be inserted into the second limiting groove 3311 for limiting position. This arrangement facilitates installation of the second limiting ring 50 in the second limiting groove 3311, thereby improving the convenience and efficiency of assembly between the second limiting ring 50 and the second limiting groove 3311.

[0093] By adopting the above-mentioned scheme, on the basis that the sliding portion 331 of the transmission member 33 is passed through and slidably connected in the slide groove 3111, the second limiting ring 50 can be installed in the second limiting groove 3311, so that the second limiting ring 50 is limited to the side of the connecting block 311 away from the substrate 10, and the sliding portion 331 can be reliably restricted from escaping the slide groove 3111, thereby reliably improving the connection stability and connection reliability between the sliding portion 331 of the transmission member 33 and the connecting block 311.

[0094] See also Figure 7 、 Figure 8In some embodiments of the present application, the transmission member 33 is a gear structure, the transmission member 33 is sleeved on the outer periphery of the rotating part 21, and rotates synchronously with the rotating part 21, the movable part 31 is provided with a rack 312, the transmission member 33 is directly engaged with the rack 312, or the transmission member 33 is indirectly engaged with the rack 312 by engaging with the adjacent transmission member 33.

[0095] It should be noted that, in this embodiment, the transmission member 33 is a gear structure that is transmission-connected between the movable member 31 and the rotating portion 21. The transmission member 33 is sleeved on the outer periphery of the portion of the rotating portion 21 that protrudes from the base plate 10, and rotates synchronously with the rotating portion 21. Based on this, the rotating portion 21 and the transmission member 33 are fixed relative to the plane position of the base plate 10, and can rotate synchronously around the same axis (basically corresponding to the central axis of the rotating hole 11). Among them, this embodiment does not limit the specific implementation method of "the transmission member 33 and the rotating portion 21 maintain synchronous rotation". For example, components such as flat keys and screws can be used to limit the transmission member 33 and the rotating portion 21 to each other in a circumferential direction so as to maintain the synchronous rotation of the two.

[0096] It should also be noted that a rack 312 is provided on the side of the movable member 31 facing the transmission member 33, and at least one rack 312 is provided. The transmission member 33 can be directly engaged with the rack 312, or indirectly engaged with the rack 312 by directly engaging with an adjacent transmission member 33, thereby achieving a transmission connection with the movable member 31. Whether the transmission member 33 is "directly engaged with the rack 312" or "directly engaged with an adjacent transmission member 33" depends primarily on the layout of the transmission members 33 and the movable member 31, and can be flexibly designed according to specific circumstances. This embodiment does not impose specific limitations on this.

[0097] Based on this, when the driving member 32 drives the movable member 31 to move back and forth along the first direction x, the meshing relationship between the rack 312 and the gear, and between the gears, can drive the transmission member 33 to drive the rotating part 21 to rotate synchronously, thereby driving the installation device 20 to rotate.

[0098] Please also refer to Figure 2By adopting the above solution, the transmission member 33, which is a gear structure, can be sleeved on the outer periphery of the rotating part 21 and rotate synchronously with the rotating part 21, and directly or indirectly mesh with the rack 312 to achieve a transmission connection between the movable member 31 and the rotating part 21. Based on this, when the driving member 32 drives the movable member 31 to reciprocate along the first direction x, the meshing relationship between the rack 312 and the gear, and between the gears, can reliably drive the transmission member 33 to drive the rotating part 21 to rotate synchronously, thereby driving the installation device 20 to rotate. As a result, the transmission member 33 can reliably drive the movable member 31 and the rotating part 21 with a simplified and reliable gear structure, and conveniently, quickly, and smoothly drive the installation device 20 to rotate, thereby improving the structural reliability and performance of the drive assembly 30 and facilitating the installation efficiency of the spring 20'. Moreover, the rotation angle of the transmission member 33 basically corresponds to the rotation angle of the installation device 20. The rotation angle of the transmission member 33 is correlated with the moving stroke of the movable member 31 along the first direction x, and is also correlated with the transmission ratio between each transmission member 33 and the movable member 31. Therefore, by adopting the above scheme, it is also beneficial to accurately determine the relationship between "the moving stroke of the movable member 31 along the first direction x", "the transmission relationship of the transmission member 33" and "the rotation angle of the installation device 20", so as to facilitate the precise control of the rotation angle of the installation device 20, which can help improve the installation accuracy and installation reliability of the spring piece 20'.

[0099] See also Figure 6 、 Figure 7 、 Figure 8 In some embodiments of the present application, a first limiting groove 211 is provided in a ring shape on the outer periphery of the rotating part 21, and the spring installation mechanism also includes a first limiting ring 40 installed in the first limiting groove 211, and the first limiting ring 40 is limited to the side of the transmission member 33 away from the substrate 10.

[0100] It should be noted that the outer periphery of the rotating portion 21 is provided with a first retaining groove 211. The first retaining groove 211 is an annular groove and extends along the circumference of the rotating portion 21. When the transmission member 33, which is a gear structure, is sleeved onto the outer periphery of the rotating portion 21, the first retaining groove 211 is located at the portion of the rotating portion 21 that extends beyond the transmission member 33. In other words, the transmission member 33 is located between the first retaining groove 211 and the base plate 10.

[0101] It should also be noted that the first limiting ring 40 is in the shape of an open ring or a closed ring. When the transmission member 33 is sleeved on the outer periphery of the rotating portion 21 and installed in place, the first limiting ring 40 can be installed in the first limiting groove 211 to limit the side of the transmission member 33 away from the substrate 10 through the first limiting ring 40, thereby limiting the transmission member 33 between the first limiting ring 40 and the substrate 10, thereby reliably preventing the transmission member 33 from escaping from the rotating portion 21, and reliably improving the position stability, connection stability, and connection reliability between the transmission member 33 and the rotating portion 21. Among them, the first limiting ring 40 can be fixedly installed or detachably installed in the first limiting groove 211, and this is not limited in this embodiment.

[0102] The first limiting ring 40 is preferably in the shape of an open ring. This configuration facilitates the installation of the first limiting ring 40 in the first limiting groove 211, thereby improving the assembly convenience and efficiency between the first limiting ring 40 and the first limiting groove 211.

[0103] By adopting the above-mentioned scheme, on the basis of the transmission member 33 of the gear structure being sleeved on the outer periphery of the rotating part 21 and maintaining synchronous rotation with the rotating part 21, the first limiting ring 40 can be installed in the first limiting groove 211 to limit the side of the transmission member 33 away from the substrate 10 through the first limiting ring 40, so as to limit the transmission member 33 between the first limiting ring 40 and the substrate 10, thereby reliably limiting the transmission member 33 from escaping from the rotating part 21, and reliably improving the position stability, connection stability and connection reliability between the transmission member 33 and the rotating part 21, thereby effectively ensuring and improving the rotation synchronization and rotation smoothness of the transmission member 33 and the rotating part 21.

[0104] Of course, in other possible embodiments, the transmission member 33 may adopt other structural forms besides the connecting rod structure and the gear structure to realize the transmission connection between the movable member 31 and the rotating part 21, and realize the conversion of the linear motion of the movable member 31 along the first direction x into the rotational motion of the mounting device 20. This embodiment does not impose any restrictions on this.

[0105] See also Figure 4 、 Figure 5 In some embodiments of the present application, the spring clip mounting mechanism also includes two positioning members 60 mounted on the substrate 10, and the two positioning members 60 are respectively arranged at opposite ends of the movable member 31 along the first direction x. The two positioning members 60 are jointly used to constrain the moving stroke of the movable member 31 in the first direction x.

[0106] It should be noted that the positioning member 60 is mounted on the side of the base plate 10 facing the drive assembly 30. Two positioning members 60 are provided, and the two positioning members 60 are arranged opposite each other along the first direction x, spaced apart, and located at opposite ends of the movable member 31 along the first direction x. Therefore, when the movable member 31 reciprocates along the first direction x, the positioning members 60 engage with the corresponding end stops of the movable member 31, positioning the movable member 31 at the end position of the end of the movable member 31. Thus, the two positioning members 60 jointly constrain the movable member 31's travel in the first direction x.

[0107] Please also refer to Figure 2 By adopting the above solution, the two positioning members 60 can jointly constrain the moving stroke of the movable member 31 in the first direction x, thereby constraining the rotation angle range of the installation device 20, thereby facilitating precise control of the rotation angle of the installation device 20, and improving the installation accuracy and installation reliability of the spring piece 20'.

[0108] See also Figure 4 、 Figure 5 In some embodiments of the present application, the movable member 31 includes a main body 313 and two positioning portions 314. The main body 313 extends along the first direction x. The two positioning portions 314 are located at opposite ends of the main body 313 along the first direction x and correspond to the two positioning members 60. In the corresponding positioning portions 314 and positioning members 60, one of the positioning portions 314 and the positioning members 60 is provided with a guide rod 3141, and the other of the positioning portions 314 and the positioning members 60 is provided with a guide hole 61. The guide rod 3141 extends through the guide hole 61.

[0109] It should be noted that the movable member 31 includes a main body 313 and two positioning portions 314. The main body 313 extends along the first direction x. The two positioning portions 314 are arranged opposite to each other and spaced apart along the first direction x, and are respectively arranged at opposite ends of the main body 313 along the first direction x. This embodiment does not impose a sole limitation on the shape of the movable member 31. For example, Figure 4 、 Figure 5 As shown, the main body 313 can be in the shape of a single rod, and the main body 313 and the two positioning parts 314 can together form an "I" shape; for example, Figure 7 、 Figure 8 As shown, the main body portion 313 may include two rod-shaped structures, and the main body portion 313 and the two positioning portions 314 may together form a rectangle.

[0110] It should also be noted that the two positioning portions 314 and the two positioning members 60 are provided in correspondence with each other. In the positioning portion 314 and the positioning member 60, which are provided in correspondence with each other on the same end side of the main body 313, the positioning portion 314 may be provided with a guide rod 3141 protruding toward the positioning member 60, and the positioning member 60 may be provided with a corresponding guide hole 61 through which the guide rod 3141 can be movably inserted; or the positioning member 60 may be provided with a guide rod 3141 protruding toward the positioning portion 314, and the positioning portion 314 may be provided with a corresponding guide hole 61 through which the guide rod 3141 can be movably inserted. In the corresponding positioning portion 314 and positioning member 60, at least one set of guide rods 3141 and guide holes 61 is provided.

[0111] Please also refer to Figure 2 By adopting the above scheme, on the one hand, during the reciprocating movement of the movable part 31 along the first direction x, the guiding cooperation between the guide rod 3141 and the guide hole 61 can be used to constrain and guide the moving direction and moving path of the movable part 31 in the first direction x, thereby improving the movement smoothness and movement accuracy of the movable part 31 in the first direction x; on the other hand, during the reciprocating movement of the movable part 31 along the first direction x, the positioning part 314 can be positioned and stopped by the positioning part 60 to constrain the end position of the positioning part 314, thereby accurately constraining the moving stroke of the movable part 31 in the first direction x by the two positioning parts 60; thereby, it is convenient to accurately constrain the rotation angle of the installation device 20, which can be beneficial to improving the installation accuracy and installation reliability of the spring piece 20'.

[0112] See also Figure 4 、 Figure 5 In some embodiments of the present application, the driving member 32 includes a driving seat 321, a driving rod 322, a driving connecting rod 323 and a driving handle 324; the driving seat 321 is installed on the substrate 10, and a first support portion 3211 is erected at the end of the driving seat 321 away from the movable member 31, and a second support portion 3212 is erected at the end of the driving seat 321 close to the movable member 31; the driving rod 322 is extended along the first direction x and is passed through the second supporting portion 3212, and the end of the driving rod 322 close to the movable member 31 is connected to the movable member 31; the driving handle 324 is rotatably connected to the first supporting portion 3211, and the driving handle 324 is transmission-connected to the end of the driving rod 322 away from the movable member 31 through the driving connecting rod 323.

[0113] It should be noted that the drive seat 321 is mounted on the substrate 10 and is located at one end side of the movable member 31. A first support portion 3211 is provided at one end of the drive seat 321 away from the movable member 31. The first support portion 3211 is vertically arranged on the third support portion 3213 of the drive seat 321 for mounting on the substrate 10. Optionally, the first support portion 3211 can be bent relative to the third support portion 3213 to facilitate processing. Optionally, the first support portion 3211 is perpendicular to the third support portion 3213 to make the state stability of the first support portion 3211 relative to the third support portion 3213 better, which can help to ensure and improve the supporting effectiveness of the first support portion 3211.

[0114] A second support portion 3212 is provided at one end of the drive base 321, proximal to the movable member 31. The second support portion 3212 is vertically mounted on the third support portion 3213 of the drive base 321. Optionally, the second support portion 3212 can be bent relative to the third support portion 3213 for ease of processing. Optionally, the second support portion 3212 can be perpendicular to the third support portion 3213 to provide greater stability relative to the third support portion 3213, thereby ensuring and enhancing the supporting effectiveness of the second support portion 3212.

[0115] It should also be noted that the drive rod 322 is extended along the first direction x and can be movably passed through the second support portion 3212. Based on this, the drive rod 322 can be reliably supported by the second support portion 3212, and on this basis, the drive rod 322 is guaranteed to have the freedom to move back and forth along the first direction x.

[0116] The end of the driving rod 322 closest to the movable member 31 is connected to the movable member 31. Based on this, the driving rod 322 and the movable member 31 can have synchronous movement, moving back and forth synchronously along the first direction x. This embodiment does not limit the specific connection method used by the end of the driving rod 322 closest to the movable member 31 and the movable member 31.

[0117] The driving handle 324 is rotatably connected to the first support portion 3211. The driving handle 324 is transmission-connected to the end of the driving rod 322 that is distal from the movable member 31 via the driving connecting rod 323. Thus, by rotating the driving handle 324 relative to the first support portion 3211, the driving rod 322 is driven via the driving connecting rod 323, causing the driving rod 322 to drive the movable member 31 to synchronously reciprocate along the first direction x. The rotation of the driving handle 324 can be driven manually or electrically, and this is not limited in this embodiment.

[0118] Please also refer to Figure 2By adopting the above solution, the driving member 32 can rotate the driving handle 324 relative to the first support portion 3211 to drive the driving rod 322 and the movable member 31 connected to the driving rod 322 to synchronously reciprocate along the first direction x via the driving connecting rod 323 that is transmission-connected between the driving handle 324 and the driving rod 322. Thus, the driving member 32 can conveniently, quickly, and smoothly drive the movable member 31 to reciprocate along the first direction x with a simplified and reliable structure, thereby improving operational convenience. This allows the driving assembly 30 to conveniently, quickly, and smoothly rotate the installation device 20, thereby improving the installation efficiency of the spring piece 20'.

[0119] See also Figure 1 、 Figure 2 、 Figure 6 In some embodiments of the present application, a first limiting structure 221 is provided on the end surface of the loading portion 22 away from the rotating portion 21 , and the first limiting structure 221 is used to cooperate with the second limiting structure 22 ′ of the spring piece 20 ′.

[0120] It should be noted that if Figure 1 、 Figure 2 As shown, in some embodiments, a second limiting structure 22' is provided on a side of the spring fragment 20' facing away from the bottom of the spring fragment slot 11'. There is at least one second limiting structure 22'. Preferably, there are multiple second limiting structures 22', distributed in a circular array around the central axis of the spring fragment 20'.

[0121] Correspondingly, a first limiting structure 221 is provided on the end face of the loading portion 22 facing away from the rotating portion 21. The first limiting structure 221 and the second limiting structure 22' are arranged in a one-to-one correspondence. The first limiting structure 221 can cooperate with the second limiting structure 22' of the spring piece 20' to limit the loading portion 22 and the spring piece 20', so that the installation device 20 drives the spring piece 20' to rotate, so as to realize the limiting installation of the spring piece 20' in the spring piece slot 11'.

[0122] In one possible embodiment, the second limiting structure 22' is a groove-shaped structure or a hole-shaped structure, and the first limiting structure 221 is a convex structure that matches the shape and size of the second limiting structure 22', so that the first limiting structure 221 and the second limiting structure 22' can achieve limiting cooperation. In another possible embodiment, the second limiting structure 22' is a convex structure, and the first limiting structure 221 is a groove-shaped structure or a hole-shaped structure that matches the shape and size of the second limiting structure 22', so that the first limiting structure 221 and the second limiting structure 22' can achieve limiting cooperation.

[0123] By adopting the above solution, the installation tool 20 can achieve positional cooperation with the second positional cooperation structure 22' of the spring piece 20' through the first position-limiting structure 221 provided on the end surface of the loading portion 22 facing away from the rotating portion 21, thereby facilitating the rotation of the spring piece 20' under the driving action of the driving assembly 30. As a result, the installation tool 20 can achieve positional cooperation with the spring piece 20' with a simplified and reliable structure, facilitating the rotation of the spring piece 20', thereby effectively ensuring and improving the processing convenience of the installation tool 20, and effectively ensuring and improving the convenience of cooperation between the installation tool 20 and the spring piece 20'.

[0124] Of course, in other possible implementations, the side of the loading portion 22 facing away from the rotating portion 21 can be positioned in conjunction with the spring 20' by vacuum adsorption or magnetic adsorption or other means, so that the mounting device 20 drives the spring 20' to rotate. This embodiment does not limit this.

[0125] See also Figure 2 、 Figure 4 、 Figure 6 In some embodiments of the present application, a pressure strip 222 is provided on the end surface of the loading portion 22 away from the rotating portion 21, and the pressure strip 222 extends radially along the loading portion 22; in the direction away from the center of the loading portion 22, the thickness of the pressure strip 222 is gradually increased.

[0126] It should be noted that a bead 222 is provided on the end surface of the loading portion 22 facing away from the rotating portion 21. The bead 222 is a convex structure. There is at least one bead 222 provided. Preferably, there are multiple beadings 222, and the multiple beadings 222 are distributed in a circular array around the central axis of the loading portion 22. The bead 222 extends radially along the loading portion 22. The radial direction of the loading portion 22 refers to the direction passing through the center of the loading portion 22 and perpendicular to the central axis of the loading portion 22. In the extension direction of the bead 222, especially in the direction away from the center of the loading portion 22, the thickness of the bead 222 is gradually increased. The thickness of the bead 222 refers to the dimension of the bead 222 in the direction away from the rotating portion 21.

[0127] Based on this, when the spring clip 20' has been placed in the first sub-slot 111' of the spring clip slot 11' of the filter cover 10', but has not been limitedly installed in the second sub-slot 112', the spring clip installation mechanism can be placed on the side of the filter cover 10' where the spring clip slot 11' is provided, and the loading part 22 of the installation device 20 is aligned with the spring clip 20' and limitedly matched. Subsequently, the loading part 22 of the installation device 20 can press the spring clip 20' through the pressure strip 222, so that the spring clip 20' enters the second sub-slot 112' from the first sub-slot 111'. Subsequently, the installation device 20 can drive the spring clip 20' to rotate under the driving action of the driving component 30, so that the spring clip 20' is limitedly installed in the second sub-slot 112'.

[0128] By adopting the above solution, when the spring clip 20' has been inserted into the spring clip slot 11' of the filter cover 10' but has not been restrained in the spring clip slot 11', the installation device 20 can engage with the spring clip 20' through the loading portion 22 and press the spring clip 20' with the pressure strip 222 on the loading portion 22, so that the spring clip 20' is deeply inserted into the spring clip slot 11'. Based on this, the installation device 20 can be driven by the drive assembly 30 to rotate the spring clip 20', thereby conveniently, quickly, and time-savingly and labor-savingly securing the spring clip 20' in the spring clip slot 11', thereby effectively improving the installation efficiency and reliability of the spring clip 20'. Furthermore, because the installation device 20 can achieve the pressing and deep insertion of the spring clip 20' into the spring clip slot 11' with a simplified and reliable structure, the installation device 20 can also effectively ensure and improve the ease of processing and operation.

[0129] Of course, in other possible implementations, the installation device 20 may use other means to press the spring piece 20 ′ into the spring piece slot 11 ′, such as providing a cylinder to push the spring piece 20 ′, etc. This embodiment does not limit this.

[0130] See also Figure 3 、 Figure 4 、 Figure 9 In some embodiments of the present application, the spring clip mounting mechanism further includes a mounting seat 70 for positioning and mounting the filter cover 10 ′.

[0131] It should be noted that the mounting base 70 is used to position and install the filter cover 10', that is, when the filter cover 10' is installed on the mounting base 70, the mounting base 70 can reliably support the filter cover 10' and position and stabilize the installation position and installation state of the filter cover 10'.

[0132] Please also refer to Figure 2 By adopting the above scheme, the filter cover 10' can be positioned and installed through the mounting seat 70 to locate and stabilize the installation position and installation state of the filter cover 10'. Based on this, the substrate 10 can be easily covered on the mounting seat 70 through alignment, and the various mounting tools 20 on the substrate 10 can be conveniently, quickly and accurately matched with the various spring clips 20' on the filter cover 10', thereby improving the convenience, efficiency and accuracy of the matching between the mounting tools 20 and the spring clips 20', and improving the installation efficiency of the spring clips 20'.

[0133] See also Figure 3 、 Figure 4 、 Figure 9 In some embodiments of the present application, one side of the substrate 10 is rotatably mounted on the mounting seat 70. Specifically, one side of the substrate 10 along its circumference is rotatably mounted on the corresponding side of the mounting seat 70.

[0134] Please also refer to Figure 2 By adopting the above solution, the substrate 10 can be easily switched between a closed state and an open state by rotating relative to the mounting seat 70. Based on this, the substrate 10 can be rotated relative to the mounting seat 70 to switch to the open state, which is set at an angle to the mounting seat 70, thereby opening the mounting seat 70 and facilitating the operator to remove and install the filter cover 10' from the mounting seat 70. Conversely, the substrate 10 can be rotated relative to the mounting seat 70 to switch to the closed state, where it is aligned and covered on the mounting seat 70, so that each mounting device 20 on the substrate 10 can be accurately matched with each spring clip 20' of the filter cover 10' that has been positioned and installed on the mounting seat 70. This improves the convenience, efficiency, and accuracy of the matching between the mounting device 20 and the spring clip 20', improves the installation efficiency of the spring clip 20', and improves the performance of the spring clip installation mechanism.

[0135] Of course, in other possible embodiments, the substrate 10 can be independently arranged relative to the mounting base 70, or can be constrained to move back and forth in a preset direction relative to the mounting base 70, so as to switch between a covering state in which it is aligned with the mounting base 70 and an open state opposite to the covering state. This embodiment does not impose any restrictions on this.

[0136] See also Figure 9 、 Figure 10 、 Figure 11 In some embodiments of the present application, the mounting seat 70 has a mounting table 74 for positioning and mounting the filter cover 10', and a locking assembly 80 is provided on the peripheral side of the mounting table 74. The locking assembly 80 is used to lock the substrate 10 when the substrate 10 is covered on the mounting seat 70.

[0137] It should be noted that the mounting base 70 has a mounting surface 74, which serves as an area for positioning and mounting the filter cover 10'. A locking assembly 80 is provided around the periphery of the mounting surface 74. When the substrate 10 is placed on the mounting base 70, the locking assembly 80 can lock the periphery of the substrate 10 or the side of the substrate 10 facing the mounting base 70, thereby stabilizing the position and state of the substrate 10 relative to the mounting base 70. The specific structure of the locking assembly 80 is not limited in this embodiment.

[0138] Please also refer to Figure 2 By adopting the above solution, when the substrate 10 is aligned and covered on the mounting seat 70, the locking assembly 80 can be used to lock the substrate 10 to stabilize the relative position and relative state of the substrate 10 relative to the mounting seat 70, thereby facilitating the reliable and stable matching state of the mounting device 20 and the spring piece 20' during the installation operation of the spring piece 20', thereby ensuring and improving the reliability of the installation operation of the spring piece 20'.

[0139] See also Figure 9 、 Figure 10 、 Figure 11 In some embodiments of the present application, one side of the substrate 10 is rotatably mounted on the mounting base 70, and the mounting base 70 has a rotating side 72 rotatably connected to the substrate 10, and a locking side 73 opposite to the rotating side 72, and the locking assembly 80 is provided on the locking side 73 of the mounting base 70.

[0140] By adopting the above solution, the substrate 10 can be conveniently switched between the closed state and the open state by rotating relative to the mounting base 70. Furthermore, when the substrate 10 is aligned and covered on the mounting base 70, the locking assembly 80 provided on the locking side 73 of the mounting base 70 can lock the substrate 10, thereby enhancing the locking effect of the substrate 10, thereby reliably stabilizing the relative position and state of the substrate 10 with respect to the mounting base 70.

[0141] See also Figure 9 、 Figure 10 、 Figure 11 In some embodiments of the present application, a mounting portion 71 is provided on the peripheral side of the mounting table 74. A mounting groove 711 is provided on the side of the mounting portion 71 facing away from the mounting table 74. A mounting hole 712 is provided at the bottom of the mounting groove 711. The locking assembly 80 includes a locking member 81, an elastic member 82, and a stopper 83. The stopper 83 is installed in the notch of the mounting groove 711. The stopper 83 is provided with a through hole 831 corresponding to the mounting hole 712. The locking member 81 is inserted into the mounting hole 712 and the through hole 831 and is used to lock the substrate 10. A stopper ring 811 is provided on the outer periphery of the locking member 81. The stopper ring 811 is located in the mounting groove 711 and is used to stop the hole of the mounting hole 712. The elastic member 82 is sleeved on the outer periphery of the locking member 81 and elastically abuts between the stopper ring 811 and the stopper 83.

[0142] It should be noted that a mounting portion 71 is provided on the peripheral side of the mounting surface 74, facing the side closest to the base plate 10. Mounting portion 71 is used to mount the locking assembly 80. When the base plate 10 is aligned and placed on the mounting base 70, mounting portion 71 is located on the peripheral side of the base plate 10. In this case, the side of mounting portion 71 facing away from the mounting surface 74 corresponds to the side of mounting portion 71 facing away from the base plate 10. A mounting groove 711 is defined on the side of mounting portion 71 facing away from the mounting surface 74. A mounting hole 712 is provided at the bottom of mounting groove 711, extending through the bottom of mounting groove 711.

[0143] It should also be noted that the locking assembly 80 includes a locking member 81, an elastic member 82 and a stop member 83. The stop member 83 is installed on the side of the mounting portion 71 facing away from the mounting table 74, and stops at the notch of the mounting groove 711, and can optionally cover the notch of the mounting groove 711. The stop member 83 is used to stop the locking member 81 and the elastic member 82 arranged in the mounting groove 711 from escaping from the notch of the mounting groove 711. The connection between the stop member 83 and the mounting portion 71 can be a fixed connection or a detachable connection, which is not limited in this embodiment. The stop member 83 is provided with a through hole 831, which is arranged corresponding to the mounting hole 712 and is used together to install and support the locking member 81.

[0144] The locking member 81 is a component used to lock with the substrate 10. The locking member 81 is inserted through the mounting hole 712 and the through hole 831. Under the action of force, the locking member 81 can reciprocate along the through direction of the mounting hole 712 and the through hole 831. Based on this, the through hole 831 and the mounting hole 712 can jointly support the locking member 81 and jointly guide and constrain the movement direction and movement path of the locking member 81. A stop ring 811 is protruded from the outer periphery of the portion of the locking member 81 located within the mounting groove 711. The radial dimension of the stop ring 811 is larger than the radial dimension of the mounting hole 712, so that the stop ring 811 can stop the opening of the mounting hole 712 near the mounting groove 711, thereby preventing the locking member 81 from escaping from the mounting hole 712. Moreover, because the stop member 83 can correspondingly prevent the locking member 81 from escaping from the notch of the mounting groove 711, the locking member 81 can be securely installed and can reliably perform its locking function. When the stop ring 811 stops at the opening of the mounting hole 712 on the side close to the mounting groove 711, the end of the locking member 81 can be level with or protrude from the opening of the mounting hole 712 on the side away from the mounting groove 711, so that the locking member 81 and the substrate 10 can be locked and matched reliably and effectively. Figure 5 、 Figure 10 As shown, in one possible embodiment, the base plate 10 is provided with a locking hole 12 corresponding to the locking member 81, and the locking member 81 can be locked with the base plate 10 by being limited in the locking hole 12 when the base plate 10 is aligned and covered on the mounting seat 70. Of course, in other possible embodiments, the locking member 81 can be locked with the base plate 10 by means of magnetic attraction or other means when the base plate 10 is aligned and covered on the mounting seat 70, and this embodiment is not limited to this.

[0145] The elastic member 82 is sleeved around the outer periphery of the portion of the locking member 81 located within the mounting groove 711. The elastic member 82 can be a spring. One end of the elastic member 82 elastically abuts against the stop ring 811, while the other end of the elastic member 82 elastically abuts against the stop member 83. As a result, the elastic member 82 provides a spring force between the stop ring 811 and the stop member 83, causing the locking member 81 to move away from the stop member 83 to lock and engage with the substrate 10.

[0146] By adopting the above solution, when the substrate 10 is aligned and covered on the mounting base 70, the locking assembly 80 can provide an elastic force between the stop ring 811 and the stop member 83 through the elastic member 82. Based on the elastic force, the stop ring 811 and the locking member 81 are urged to move in a direction away from the stop member 83 until the stop ring 811 stops at the opening of the mounting hole 712 on the side close to the mounting groove 711, so that the locking member 81 is locked and engaged with the substrate 10. Based on this, it is ensured that the locking assembly 80 can reliably and effectively lock the substrate 10 when the substrate 10 is aligned and covered on the mounting base 70 with a simplified and reliable structure, thereby stabilizing the relative position and state of the substrate 10 with respect to the mounting base 70. On the contrary, when the substrate 10 rotates (or moves) relative to the substrate 10, the locking member 81 can overcome the elastic force of the elastic member 82 under the pushing action of the corresponding side of the substrate 10 and move in the direction close to the stop member 83 to release the lock and obstruction of the substrate 10, thereby facilitating the state switching of the substrate 10.

[0147] See also Figure 3 、 Figure 4 In some embodiments of the present application, the spring clip mounting mechanism further includes a protective cover 90 mounted on the base plate 10. The protective cover 90 at least covers each rotating portion 21 and a portion of the driving assembly 30. The protective cover 90 and the base plate 10 may be detachably or fixedly connected, which is not limited in this embodiment.

[0148] By adopting the above-mentioned solution, the protective cover 90 can at least cover a part of each rotating part 21 and the driving assembly 30 to shield and protect each rotating part 21 and the driving assembly 30. Based on this, the risk of each rotating part 21 and the driving assembly 30 being damaged by collision with foreign objects can be effectively reduced, which can help to protect and extend the service life of the shrapnel installation mechanism.

[0149] Based on the above embodiments and figures, the operation process of the spring installation mechanism provided in the embodiment of the present application can be summarized as follows:

[0150] First, the substrate 10 is rotated relative to the mounting seat 70 to switch the substrate 10 to an open state set at an angle to the mounting seat 70 to open the mounting seat 70. At this time, it is convenient for the operator to position and install the filter cover 10' with the spring clip 20' to be limited and installed on the mounting seat 70. In addition, on the filter cover 10', the spring clip 20' has been placed in the spring clip slot 11' of the filter cover 10' but has not been limited and installed in the spring clip slot 11'.

[0151] Subsequently, the driving handle 324 is rotated in the reverse direction relative to the first support portion 3211 (this is relative to the forward rotation described below), thereby driving the driving rod 322 via the driving connecting rod 323, thereby driving the driving rod 322 and the movable member 31 to synchronously reciprocate along the first direction x. The transmission member 33, which is connected between the movable member 31 and the rotating portion 21, then converts the movement of the movable member 31 into rotation of the mounting device 20, thereby rotating the mounting device 20 to its initial state.

[0152] Subsequently, the substrate 10 is rotated relative to the mounting base 70 to switch the substrate 10 to a covered state aligned with the mounting base 70. At this time, the mounting fixture 20, which has been adjusted to the initial state, can accurately align with the spring 20' of the filter cover 10', and the first limiting structure 221 on the loading portion 22 can correspondingly limit and cooperate with the second limiting structure 22' of the spring 20'. The pressure strip 222 on the loading portion 22 can press the spring 20' to press the spring 20' from the first sub-slot 111' of the spring slot 11' into the second sub-slot 112'. At the same time, the locking assembly 80 can use the elastic member 82 to force the stop ring 811 and the locking member 81 to move in a direction away from the stop member 83 until the stop ring 811 stops at the opening of the mounting hole 712 on the side near the mounting slot 711, so that the locking member 81 is locked and engaged with the substrate 10, thereby stabilizing the relative position and relative state of the substrate 10 relative to the mounting base 70.

[0153] Subsequently, the driving handle 324 is rotated forward relative to the first support portion 3211, thereby driving the driving rod 322 via the driving connecting rod 323, thereby driving the driving rod 322 and the movable member 31 to synchronously reciprocate along the first direction x. The transmission member 33, which is connected between the movable member 31 and the rotating portion 21, then converts the movement of the movable member 31 into rotation of the installation device 20, thereby driving the installation device 20 and the spring clip 20' to synchronously rotate, so that the spring clip 20' is fixedly installed in the second sub-slot 112' of the spring clip slot 11'. Among them, "forward rotation" and "reverse rotation" are two relative concepts, which are determined according to the movement relationship between the driving handle 324, the driving connecting rod 323, the driving rod 322, the movable part 31, the transmission part 33 and the installation device 20. For example, the "forward rotation" of the driving handle 324 can be a rotation toward the side close to the movable part 31 (that is, rotation toward the side of the "tight" mark in the figure), while the "reverse rotation" is a rotation toward the side away from the movable part 31 (that is, rotation toward the side of the "loose" mark in the figure).

[0154] Subsequently, the substrate 10 is rotated relative to the mounting seat 70 to switch the substrate 10 to an open state at an angle to the mounting seat 70 to open the mounting seat 70. At this time, the operator can easily remove the filter cover 10' with the spring clip 20' installed in a limited position from the mounting seat 70.

[0155] At this point, one round of installation of the spring pieces 20 ′ of the filter cover plate 10 ′ is completed, and the process can be repeated to perform the installation of the spring pieces 20 ′ of each filter cover plate 10 ′ in batches.

[0156] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
