Description

Technical Field

[0001] This invention relates to the field of filter technology, and in particular to a filter. Background Technology

[0002] As people's living standards improve, they have higher requirements for drinking water quality, and water purifiers have become widely popular. Water purifiers can be connected to municipal tap water, well water, and other raw water sources, allowing users to directly drink the water flowing from the filter.

[0003] The filter includes a filter element assembly and a connector, which is an intermediate seat for connecting the inlet and outlet pipes to the filter element assembly. In existing filters, the filter element assembly and the connector are generally assembled and connected by a threaded connection. This type of connection requires additional disassembly and assembly tools and has problems such as low connection efficiency, high manufacturing cost, and complex structure. Summary of the Invention

[0004] The main objective of this invention is to provide a filter that is simple in structure, low in production cost, easy to install and replace, and easy to operate.

[0005] To achieve the above objectives, the filter proposed in this invention includes:

[0006] A filter element assembly, one end of which has a connecting groove, an inlet, and an outlet. The wall of the connecting groove is recessed into a mounting groove facing away from the center. The mounting groove also contains a movable component and a first elastic component. One end of the first elastic component is connected to the bottom of the mounting groove, and the other end elastically abuts against the movable component. The movable component movably passes through the mounting groove. The surface of the movable component facing one end of the filter element assembly is inclined, and the inclined surface is inclined from one end near the first elastic component to the other end.

[0007] The connecting seat includes a seat body and a locking assembly. The seat body has a water inlet connector and a water outlet connector. The water inlet connector has a water inlet channel, and the water outlet connector has a water outlet channel. The locking assembly includes a first conical fastener, a second conical fastener, and a second elastic member. One end of the first conical fastener is connected to the surface of the seat body, and the second conical fastener is movably sleeved on the side of the first conical fastener near the seat body. The conical extension directions of the first conical fastener and the second conical fastener are opposite to each other. One end of the second elastic member is connected to the surface of the seat body, and the other end elastically abuts against one end face of the filter element assembly.

[0008] The connecting seat and the filter element assembly have a first driving locking state, so that the water inlet channel connects to the water inlet and the water outlet channel connects to the water outlet, and a second driving disengagement state.

[0009] Optionally, the maximum diameter of the second tapered fastener is greater than the maximum diameter of the first tapered fastener.

[0010] Optionally, the connecting seat further includes a connecting post, the connecting post including a limiting part and a connecting part connected together, the diameter of the limiting part being larger than the diameter of the connecting part, the limiting part being connected to the surface of the seat body, the end of the connecting part away from the limiting part being connected to the first conical fastener, the second conical fastener being movably sleeved on the connecting part, and the end face of the second conical fastener facing away from the first conical fastener abutting against the limiting part.

[0011] Optionally, there may be multiple second elastic elements, which are spaced apart circumferentially along the connecting post.

[0012] Optionally, the filter element assembly includes a filter element body and a filter element cover. The filter element cover has a through inlet and an outlet. One end of the filter element cover is connected to the filter element body. Both the inlet and the outlet are connected to the filter element body. The other end has a connecting groove. The other end of the second elastic member elastically abuts against the other end face of the filter element cover.

[0013] The connecting seat and the filter cover have a first driving locked state and a second driving disengaged state.

[0014] Optionally, there are two movable parts and two first elastic parts, and two mounting slots are provided in the connecting groove. The two mounting slots are arranged opposite to each other, and one movable part and one first elastic part are respectively disposed in one mounting slot.

[0015] Optionally, the two opposite end faces of the two movable parts are joined to form a circular opening, the diameter of which is smaller than the maximum diameter of the first conical fastener and smaller than the maximum diameter of the second conical fastener.

[0016] Optionally, the mounting groove is further provided with a mounting seat and a first movable column. The mounting seat is connected to the bottom of the mounting groove. One end of the first movable column is movably inserted through the mounting seat, and the other end is connected to the movable component. The first elastic member is sleeved on the first movable column, and the two ends of the first elastic member abut against the mounting seat and the movable component, respectively.

[0017] Optionally, the mounting groove has a limiting groove in its wall, the limiting groove extends along the extension direction of the mounting groove, and the side surface of the mounting base is provided with a limiting member, which is inserted into the limiting groove.

[0018] Optionally, the mounting groove may have multiple limiting grooves, which are spaced apart along the sidewall of the mounting groove. The mounting base may have multiple limiting members along its circumference, with each limiting member inserted into a corresponding limiting groove.

[0019] In the technical solution of this invention, a connecting groove is provided at one end of the filter element assembly. The groove wall of the connecting groove is recessed in a direction away from the center, and a movable member and a first elastic member are provided in the mounting groove. The movable member is movably inserted into the mounting groove by the support of the first elastic member, and has an inclined surface in the direction of the opening of the connecting groove. The connecting seat includes a seat body and a locking assembly. The locking assembly includes a first conical fastener, a second conical fastener, and a second elastic member. One end of the first conical fastener is connected to the surface of the seat body, and the second conical fastener is movably sleeved on the side of the first conical fastener near the seat body. The conical extension directions of the first and second conical fasteners are opposite to each other. One end of the second elastic member is connected to the surface of the seat body, and the other end elastically abuts against one end face of the filter element assembly. The connecting seat and the filter element cover have a locked state and a separated state.

[0020] When the seat is driven for the first time, the first conical fastener is inserted into the connecting groove. Its conical surface presses against the movable part to open and compress the first elastic part and the second elastic part, so that the movable part is engaged between the first conical fastener and the second conical fastener, and the connecting seat and the filter element assembly are converted to a locked state.

[0021] In the second drive, the first and second conical fasteners continue to be inserted into the connecting groove. The end face of the second conical fastener facing the direction of movement presses against the inclined surface of the movable part, causing the movable part to open, compress the first elastic element, and extend into the mounting groove. As the movable part is continuously inserted, it opens to the size of the end plane of the second conical fastener, and then slides along the conical outer surface of the second conical fastener. The movable part extends out of the mounting groove due to the rebound force of the first elastic element, and has a holding force against the conical surface of the second conical fastener towards the first conical fastener, causing the second conical fastener to move towards the first conical fastener and mate with it. The drive body stops, the second elastic element returns to its original position, and the drive body moves in the opposite direction. The movable part slides along the outer surfaces of the mated second and first conical fasteners, and after passing the conical surface of the first conical fastener, it disengages from the locking assembly, realizing the separation of the movable part from the locking assembly. The connecting seat and the filter cover are then switched to a separated state.

[0022] The filter element assembly and the connecting seat are connected and separated by a first-drive limiting engagement and a second-drive pressing separation action, which, through continuous driving of the seat body, makes the filter element cover and the connecting seat easy to operate and highly efficient. Furthermore, the first and second conical fasteners have simple structures, and their production molds are simple in structure, resulting in low manufacturing costs. Attached Figure Description

[0038] This invention proposes a filter 1.

[0039] In embodiments of the present invention, such as Figures 1 to 7As shown, the filter 1 includes a filter element assembly 10 and a connecting seat 50; one end of the filter element assembly 10 is provided with a connecting groove 131, and the groove wall of the connecting groove 131 is recessed with an installation groove 1311 in the direction away from the center; the installation groove 1311 is also provided with a movable member 14 and a first elastic member 15, one end of the first elastic member 15 is connected to the bottom of the installation groove 1311, and the other end elastically abuts against the movable member 14, the movable member 14 is movably inserted through the installation groove 1311, and the side surface of the movable member 14 facing one end of the filter element assembly 10 is an inclined surface, the inclined surface is inclined from one end near the first elastic member 15 to the other end; the connecting seat 50 includes a seat body 51 and a locking assembly 53, the seat body is provided with a water inlet connector and a water outlet connector, the water inlet connector is provided with a water inlet channel 511, and the water outlet connector is provided with a water inlet channel 511. The device has a water outlet channel 513. The locking assembly 53 includes a first conical fastener 532, a second conical fastener 533, and a second elastic member 534. One end of the first conical fastener 532 is connected to the surface of the base 51. The second conical fastener 533 is movably sleeved on the side of the first conical fastener 532 near the base 51. The conical extension directions of the first conical fastener 532 and the second conical fastener 533 are opposite to each other. One end of the second elastic member 534 is connected to the surface of the base 51, and the other end elastically abuts against one end face of the filter element assembly 10. The connecting seat 50 and the filter element assembly 10 have a first driving locking state of the base 51, so that the water inlet channel 511 connects to the water inlet 133 and the water outlet channel 513 connects to the water outlet 135, and a second driving separation state of the base 51.

[0040] The filter 1 includes a filter element assembly 10 and a connecting seat 50. One end of the filter element assembly 10 has a connecting groove 131. The groove wall of the connecting groove 131 is recessed into a mounting groove 1311 in a direction away from the center. A movable member 14 and a first elastic member 15 are disposed within the mounting groove 1311. One end of the first elastic member 15 is connected to the bottom of the mounting groove 1311, and the other end elastically abuts against the movable member 14. When the first elastic member 15 is in a relaxed state, the movable member 14 extends out of the mounting groove 1311. When a certain pressure is applied to the movable member 14, part of the movable member 14 extends into the mounting groove 1311, and the first elastic member 15 is compressed. The surface of the movable member 14 facing one end of the filter element assembly 10 is an inclined surface. The inclined surface is inclined from one end near the first elastic member 15 to the other end. The connecting seat 50 includes a seat body 51 and a locking assembly 53. The locking assembly 53 includes a first conical fastener 532 and a second conical fastener 533. When the first elastic member 15 is in the relaxed state, the initial position of the movable member 14 is set at a position close to the central axis of the first conical fastener 532 and the second conical fastener 533. Therefore, when the first conical fastener 532 or the second conical fastener 533 abuts against the movable member 14, it has a compressive effect on the first elastic member 15. The first elastic member 15 can be a spring, a sheet, an elastic colloid, etc., which is not limited here.

[0041] Furthermore, when the connecting seat 50 is connected to the filter element assembly 10, the water inlet channel 511 is connected to the water inlet 133 of the filter element assembly 10, and the water outlet channel 513 is connected to the water outlet 135 of the filter element assembly 10, thus forming a connection between the connecting seat 50 and the filter element body 11. The water inlet channel 511 and the water outlet channel 513 can then be connected to external pipes.

[0042] Furthermore, the locking assembly 53 also includes a second elastic element 534. One end of the second elastic element 534 is connected to the surface of the seat 51, and the other end elastically abuts against one end face of the filter element assembly 10. When the connecting seat 50 is not connected to the filter element assembly 10, the second elastic element 534 is in a relaxed state. When the connecting seat 50 is connected to the filter element assembly 10, that is, when the first conical fastener 532 is inserted into the receiving groove, the second elastic element 534 is compressed. The second elastic element 534 can be a spring, a sheet, an elastic gel, etc., and is not limited here.

[0043] Furthermore, the side surfaces of both the first conical fastener 532 and the second conical fastener 533 are conical, meaning their diameter gradually decreases from one end to the other. It is understood that the inclination of the conical surfaces of the first conical fastener 532 and the second conical fastener 533 can be the same, or the inclination of the first conical fastener 532 can be greater than that of the second conical fastener 533, facilitating the smooth sliding of the movable part 14 along the outer surface of the first conical fastener 532. In this embodiment, the conical extension directions of the first conical fastener 532 and the second conical fastener 533 are opposite, meaning the cone angle of the first conical fastener 532 faces away from the seat 51, while the cone angle of the second conical fastener 533 faces towards the seat 51, and the opposite end faces of the first conical fastener and the second conical fastener 533 are both planar.

[0044] With this configuration, in conjunction with the inclined surface of the movable part 14, along the installation and insertion direction of the connecting seat 50 and the filter element assembly 10, when the first conical fastener 532 moves in the insertion direction, it can open the movable part 14. Since the second conical fastener 533 is in the initial position with a certain distance from the first conical fastener 532, a fastening groove is formed at the distance between them. When the movable part 14 is opened and slides along the first conical fastener 532, it can slide into the groove, forming a locking mechanism between the movable part 14 and the first conical fastener 532 and the second conical fastener 533. Due to the rebound of the first elastic member 15, the movable part 14 can be maintained in the groove. This results in the movable part 14 having a limiting effect in the insertion direction on both the first conical fastener 532 and the second conical fastener 533. Consequently, a locking position is formed between the filter element assembly 10 and the connecting seat 50, preventing relative movement between them and achieving a tight connection.

[0045] Furthermore, the movable member 14 is located between the first conical fastener 532 and the second conical fastener 533. When the driving seat 51 causes the second conical fastener 533 to move in the insertion direction, the end face of the second conical fastener 533 can exert a force on the inclined surface in the direction of insertion and in the direction of mounting groove 1311, which also has an opening function on the movable member 14. When the opening distance of the movable member 14 reaches the diameter of the end face of the second conical fastener 533, the second conical fastener 533 is continued to be driven to move in the insertion direction, and the movable member 14 and the second conical fastener 533... The conical side surface contacts and presses against the movable member 14; however, as the movable member 14 moves along the side surface, the distance between the side surface and the mounting groove 1311 increases, reducing the force on the movable member 14. Through the rebound of the first elastic member 15, the movable member 14 can keep the outer surface of the second conical fastener 533 pressed against it, exerting a force on the second conical fastener 533 in the insertion direction. Consequently, the movable member 14 can push the second conical fastener 533 in the opposite direction towards the first conical fastener 532, so that the two abut against each other. When the second conical fastener 533 abuts against the first conical fastener 532, the drive connecting seat 50 stops, the second elastic member 534 rebounds, and both the first conical fastener 532 and the second conical fastener 533 move in the opposite direction of the insertion direction. Then, the movable member 14 slides sequentially from the outer surface of the second conical fastener 533 to the outer surface of the first conical fastener 532, finally disengaging from the end of the first conical fastener 532, thus unlocking and separating the filter element assembly 10 from the connecting seat 50. Furthermore, after the movable member 14 disengages, the first elastic member 15 rebounds, causing the movable member 14 to return to its initial position. Since the second conical fastener 533 is no longer under the force of the movable member 14, it separates from the first conical fastener 532, returns to its initial position, and can be locked again.

[0046] In this embodiment, the connecting seat 50 and the filter cover 13 have a locked state and a separated state, and the switching steps between the two are as follows:

[0047] When the seat 51 is driven for the first time, the first conical fastener 532 is inserted into the connecting groove 131. Its conical surface presses against the movable part 14 to open and compress the first elastic part 15 and the second elastic part 534, so that the movable part 14 is engaged between the first conical fastener 532 and the second conical fastener 533, and the connecting seat 50 and the filter element assembly 10 are converted to a locked state.

[0048] In the second drive seat 51, the first conical fastener 532 and the second conical fastener 533 continue to be inserted into the connecting groove 131. The end face of the second conical fastener 533 facing the direction of movement presses against the inclined surface of the movable member 14, causing the movable member 14 to open, compress the first elastic member 15, and extend into the mounting groove 1311. As the movable member 14 is continuously inserted, it opens to the size of the end plane of the second conical fastener 533, and then slides along the conical outer surface of the second conical fastener 533. The movable member 14 extends out of the mounting groove 1311 due to the rebound force of the first elastic member 15, and for the second... The conical surface of the conical fastener 533 has a supporting force toward the first conical fastener 532, causing the second conical fastener 533 to move toward the first conical fastener 532 and engage with it. The drive body 51 is stopped, the second elastic member 534 returns to its original position and drives the body 51 to move in the opposite direction. The movable member 14 slides along the outer surfaces of the engaged second conical fastener 533 and the first conical fastener 532, and after passing the conical surface of the first conical fastener 532, it disengages from the locking assembly 53, thus separating the movable member 14 from the locking assembly 53. The connecting seat 50 and the filter cover 13 are then switched to a separated state.

[0049] The technical solution of this invention achieves the connection and separation of the filter element cover 13 and the connecting seat 50 through the first driving limiting engagement and the second driving pressing separation action of the locking component 53 on the connecting seat 50, by continuously driving the seat body 51. The operation is simple and the connection efficiency is high. Furthermore, the first conical fastener 532 and the second conical fastener 533 have simple structures, and the mold structure for their production is simple, resulting in low manufacturing cost.

[0050] In one embodiment of the present invention, such as Figure 6 As shown, the maximum diameter of the second tapered fastener 533 is greater than the maximum diameter of the first tapered fastener 532.

[0051] In this embodiment, the maximum diameter of the second conical fastener 533 is greater than the maximum diameter of the first conical fastener 532. When the second conical fastener 533 abuts against the first conical fastener 532, the drive connecting seat 50 stops, and the second elastic member 534 rebounds. That is, when the movable member 14 moves along the outer surface of the second conical fastener 533 and the connection between the two to the outer surface of the first conical fastener 532, the diameter of the connecting end face of the second conical fastener 533 is greater than the diameter of the connecting end face of the first conical fastener 532. The sliding of the movable member 14 can directly move from the outer surface of the second conical fastener 533 to the outer surface of the first conical fastener 532, avoiding the situation where the movable member 14 slides to the connection between the two. This ensures the effect of the movable member 14 disengaging from the outer surface of the second conical fastener 533 and releasing it from the locking assembly 53, and improves the stability of the movable member 14 when it transitions from the locked state to the separated state.

[0052] In one embodiment of the present invention, such as Figures 5 to 7As shown, the connecting seat 50 also includes a connecting post 531. The connecting post 531 includes a limiting part 5311 and a connecting part 5313 connected to each other. The diameter of the limiting part 5311 is larger than the diameter of the connecting part 5313. The limiting part 5311 is connected to the surface of the seat body 51. The end of the connecting part 5313 away from the limiting part 5311 is connected to a first conical fastener 532. A second conical fastener 533 is movably sleeved on the connecting part 5313. The end face of the second conical fastener 533 away from the first conical fastener 532 abuts against the limiting part 5311.

[0053] In this embodiment, the connecting seat 50 further includes a connecting post 531, which includes a limiting part 5311 and a connecting part 5313 connected to each other. The diameter of the limiting part 5311 is larger than the diameter of the connecting part 5313. The end of the connecting part 5313 away from the limiting part 5311 is connected to a first conical fastener 532, and a second conical fastener 533 is movably sleeved on the connecting part 5313. When in the locked state, the movable member 14 is engaged with the outer surface of the connecting part 5313. Furthermore, when the second conical fastener 533 is pushed by the movable member 14 before it is in the initial state and locked state, the second conical fastener 533 can abut against the limiting part 5311. The limiting part 5311 can maintain the relative movement of the second conical fastener 533 on the connecting post 531, limiting the movement distance of the second conical fastener 533. This ensures the relative distance between the second conical fastener 533 and the first conical fastener 532 when it is in the locked state, thus improving the abutment effect of the second conical fastener 533 against the movable member 14.

[0054] Furthermore, the diameter of the limiting part 5311 is greater than or equal to the minimum diameter of the second conical fastener 533. This setting can prevent the movable part 14 from sliding onto the limiting part 5311 and maintain the effect of the movable part 14 sliding on the outer surface of the second conical fastener 533.

[0055] In one embodiment of the present invention, such as Figure 5 , Figure 7 As shown, there are multiple second elastic elements 534, which are spaced apart circumferentially along the connecting post 531.

[0056] In this embodiment, there are multiple second elastic elements 534, which are spaced apart circumferentially along the connecting post 531. The second elastic elements 534 exert opposing forces on the tightness of the connecting seat 50 and the filter element assembly 10 in the locked state, and on their separation and ejection during the transition state. When there are multiple second elastic elements 534, they can exert the same elastic force at different positions between the end faces of the connecting seat 50 and the filter element assembly 10, maintaining consistent forces at different positions of the connecting seat 50 and the filter element assembly 10, thus ensuring consistent overall movement distance and improving stability.

[0057] Furthermore, a guide post can be provided on the surface of the seat 51 facing the filter element assembly 10. The guide post extends along the extension direction of the filter element assembly 10. The second elastic member 534 is sleeved on the guide post. The guide post can restrict the direction of the elastic force of the second elastic member 534, so as to keep the force of the connecting seat 50 and the filter element assembly 10 consistent at different positions.

[0058] In one embodiment of the present invention, such as Figures 1 to 4 As shown, the filter element assembly 10 includes a filter element body 11 and a filter element cover 13. One end of the filter element cover 13 is connected to the filter element body 11, and the other end is provided with a connecting groove 131. The other end of the second elastic member 534 elastically abuts against the other end face of the filter element cover 13.

[0059] The connecting seat 50 and the filter cover 13 have a first driving seat 51 locked state and a second driving seat 51 separated state.

[0060] In this embodiment, the filter element assembly 10 includes a filter element body 11 and a filter element cover 13. The filter element body 11 includes a housing and a filter element for installation and fixation of the filter element. One end of the filter element cover 13 is connected to the end opening of the housing, and the other end is connected to a connecting seat 50. The connecting seat 50 is provided with an inlet channel 511 and an outlet channel 513. When the connecting seat 50 is connected to the filter element cover 13, the inlet channel 511 communicates with the inlet 133 of the filter element cover 13, and the outlet channel 513 communicates with the outlet 135 of the filter element cover 13, forming a connection between the connecting seat 50 and the filter element body 11. The inlet channel 511 and the outlet channel 513 can then be connected to external pipes. The filter element cover 13 can serve as an intermediate connector for connecting the filter element body 11 to external pipes, achieving a quick and effective connection.

[0061] In one embodiment of the present invention, such as Figure 2 , Figure 4 , Figure 5 , Figure 7As shown, there are two movable parts 14 and two first elastic parts 15. The connecting groove 131 has two mounting grooves 1311. The two mounting grooves 1311 are arranged opposite to each other. One movable part 14 and one first elastic part 15 are respectively arranged in one mounting groove 1311.

[0062] In this embodiment, there are two movable members 14 and two first elastic members 15. The connecting groove 131 has two mounting grooves 1311, which are arranged opposite each other. One movable member 14 and one first elastic member 15 are respectively disposed within one mounting groove 1311. With the two mounting grooves 1311 opposite each other and the two movable members 14 and the first elastic members 15 respectively disposed within the two mounting grooves 1311, when the locking assembly 53 is inserted into the connecting groove 131, the movable members 14 located on opposite sides of the mounting groove 1311 can simultaneously perform locking operations on the locking assembly 53. This achieves simultaneous limiting and locking operations between different positions of the filter cover 13 and the locking assembly 53, improving the locking tightness and effectiveness of the filter cover 13 and the connecting seat 50.

[0063] Furthermore, the number of mounting slots 1311, movable members 14, and first elastic members 15 can also be three, four, five, etc., and is not limited here. Multiple mounting slots 1311 are arranged at intervals along the circumferential direction of the groove wall of the connecting groove 131, and a movable member 14 and a first elastic member 15 are respectively arranged in a mounting slot 1311.

[0064] In one embodiment of the present invention, such as Figure 4 , Figure 5 , Figure 7 As shown, the two opposite end faces of the two movable parts 14 are joined together to form a circular opening. The diameter of the circular opening is smaller than the maximum diameter of the first conical fastener 532 and smaller than the maximum diameter of the second conical fastener 533.

[0065] In this embodiment, the two opposite end faces of the two movable members 14 form a circular opening. The diameter of the circular opening is smaller than the maximum diameter of the first conical fastener 532 and smaller than the maximum diameter of the second conical fastener 533. The circular opening serves two purposes: firstly, it allows for the abutment and engagement of the movable member 14 with the connecting post 531. The circular opening surrounds the outer periphery of the connecting portion 5313 of the connecting post 531, ensuring a secure fastening effect between the movable member 14 and the first and second conical fasteners 532. Secondly, the movable member 14 slides sequentially from the outer surface of the second conical fastener 533 to the outer surface of the first conical fastener 532, and finally disengages from the end of the first conical fastener 532. This ensures the effective disengagement of the movable member 14 from the end of the first conical fastener 532, guaranteeing the separation of the filter cover 13 from the connecting seat 50.

[0066] In one embodiment of the present invention, such as Figure 2 , Figure 4 , Figure 5 , Figure 7 As shown, the mounting groove 1311 is also provided with a mounting base 16 and a first movable column 17. The mounting base 16 is connected to the bottom of the mounting groove 1311. One end of the first movable column 17 is movably inserted through the mounting base 16, and the other end is connected to the movable member 14. The first elastic member 15 is sleeved on the first movable column 17, and the two ends of the first elastic member 15 abut against the mounting base 16 and the movable member 14 respectively.

[0067] In this embodiment, the mounting groove 1311 is further provided with a mounting base 16 and a first movable post 17. The mounting base 16 is connected to the bottom of the mounting groove 1311, and one end of the first movable post 17 is movably inserted through the mounting base 16. The mounting base 16 is provided to maintain the position of the first elastic member 15 and the first guide post within the mounting groove 1311, thus maintaining the position and direction of movement of the first elastic member 15 and the movable member 14. The first movable post 17 is provided to maintain the connection position between the first elastic member 15 and the mounting base 16 and the movable member 14, thus maintaining the position and direction of the elastic force exerted by the first elastic member 15 on the movable member 14.

[0068] In one embodiment of the present invention, such as Figures 2 to 5 As shown, the mounting groove 1311 has a limiting groove 131a in its groove wall. The limiting groove 131a extends along the extension direction of the mounting groove 1311. The side surface of the mounting base 16 is provided with a limiting member 161, which is inserted into the limiting groove 131a.

[0069] In this embodiment, a limiting groove 131a is formed in the wall of the mounting groove 1311. The limiting groove 131a extends along the extending direction of the mounting groove 1311. A limiting member 161 is provided on the side surface of the mounting base 16, and the limiting member 161 is inserted into the limiting groove 131a. The cooperation between the limiting member 161 and the limiting groove 131a can restrict the movement of the mounting base 16 in the circumferential direction within the mounting groove 1311, thereby restricting the circumferential movement of the first movable column 17 and the movable member 14, maintaining the movement direction and angle of the movable member 14, and ensuring that the connection position between the movable member 14 and the locking assembly 53 remains unchanged.

[0070] In one embodiment of the present invention, such as Figures 2 to 5 As shown, the mounting groove 1311 has multiple limiting grooves 131a, which are spaced apart along the side wall of the mounting groove 1311. The mounting base 16 has multiple limiting members 161 along the circumferential direction, and each limiting member 161 is inserted into a limiting groove 131a.

[0071] In this embodiment, the mounting groove 1311 has multiple limiting grooves 131a, which are spaced apart along the sidewall of the mounting groove 1311. The mounting base 16 has multiple limiting members 161 along its circumference, with each limiting member 161 inserted into a corresponding limiting groove 131a. The multiple limiting grooves 131a enhance the limiting force on the circumferential movement of the mounting base 16 within the mounting groove 1311, thereby limiting the circumferential movement of the first movable column 17 and the movable member 14, maintaining the movement direction and angle of the movable member 14, and ensuring that the connection position between the movable member 14 and the locking assembly 53 remains unchanged.

[0072] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
