Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a magnet installation tool for a high-frequency ventilator and a use method thereof. Background Art

[0002] The high-frequency generator is the core component of the high-frequency ventilator and a key device for achieving high-frequency oscillating airflow. At present, it generally drives the diaphragm in the closed cavity to make bidirectional movements through the reciprocating motion of the motion shaft to generate oscillating airflow. The driving of the motion shaft in the high-frequency generator is completed by the voice coil motor, which is a device that converts electrical energy into mechanical energy and realizes linear and limited swing angle movement. The working principle of the voice coil motor is based on the electromagnetic principle, that is, the interaction between the magnetic poles of the magnetic field generated by the permanent magnetic field or the energized wire is used to drive the motor to move regularly.

[0003] like Figure 1 As shown, in the structure of the voice coil motor, eight NdFeB magnets 2 are precisely arranged along the circumference in the placement groove 11 of the base 1. The NdFeB magnets 2 are tile-shaped and have a certain curvature, and can be tightly adsorbed and fitted on the inner circumferential wall of the placement groove 11. As permanent magnets, they are key components of the voice coil motor. In the related art, the installation method for such high-performance NdFeB magnets 2 is to manually slowly place the NdFeB magnets 2 into the base 1, and the NdFeB magnets 2 are adsorbed on the inner circumferential wall of the placement groove 11 of the base 1. Then, a flange is installed on the base 1 to limit the axial movement of the NdFeB magnets 2, and the installation of the NdFeB magnets 2 is completed. However, in the process of manually placing the NdFeB magnets 2, it is impossible to accurately arrange the NdFeB magnets 2 in sequence along the circumferential direction and attach them to the inner circumferential wall of the placement groove 11 of the base 1 at one time. The position of the NdFeB magnets 2 needs to be moved many times, and the operation process is cumbersome and inefficient. More importantly, the NdFeB magnets 2 themselves are highly brittle and have extremely strong magnetism. Therefore, they are easily broken by collision during the installation process, which not only affects the performance of the motor, but also may cause harm to the operator. Summary of the invention

[0004] The problem solved by the invention is: how to improve the installation accuracy and efficiency during the installation of the NdFeB magnets of a high-frequency ventilator, while avoiding the NdFeB magnets from being broken due to manual installation, so as to protect the integrity of the NdFeB magnets and the safety of operators.

[0046] like Figure 2 , Figure 3 , Figure 4As shown, a magnet installation tool for a high-frequency ventilator provided by an embodiment of the present invention includes: a positioning mechanism 3, the positioning mechanism 3 includes a fixed cylinder 31 and a plurality of baffles 32, the fixed cylinder 31 is used to be placed in the placement groove 11 of the base 1, and a storage area is formed between the outer peripheral wall of the fixed cylinder 31 and the inner peripheral wall of the placement groove 11, and the baffles 32 are evenly spaced and connected to the outer peripheral wall of the fixed cylinder 31 along the circumferential direction, and a side edge of the baffle 32 away from the fixed cylinder 31 abuts against the inner peripheral wall of the placement groove 11 to divide the storage area into a plurality of storage grooves 33;

[0047] The mounting sleeve 4 has a plurality of mounting grooves 41 evenly spaced along the circumferential direction on the wall of the mounting sleeve 4. The mounting grooves 41 extend along the axial direction. An insertion opening 411 is provided at one end of the mounting groove 41 close to the fixing cylinder 31. The insertion opening 411 is used to place the NdFeB magnet 2 into the mounting groove 41. The outer peripheral wall of the mounting sleeve 4 is provided with a sliding channel 412 extending along the axial direction and penetrating the mounting groove 41.

[0048] The pressing ring 5 is slidably mounted on the outer wall of the mounting sleeve 4. A plurality of push blocks 51 are evenly spaced along the circumferential direction on the inner side of the pressing ring 5. The push blocks 51 are inserted into the mounting groove 41 through the sliding channel 412 and are located on the side of the NdFeB magnet 2 away from the fixed cylinder 31. The pushing blocks 51 are driven by the pressing ring 5 to move along the sliding channel 412 to push the NdFeB magnet 2 out of the mounting groove 41 through the insertion port 411 and into the storage groove 33.

[0049] Specifically, the fixed cylinder 31 in the positioning mechanism 3 is placed in the placement groove 11 of the base 1, and a storage area is formed between the fixed cylinder 31 and the inner peripheral wall of the placement groove 11. On the outer peripheral wall of the fixed cylinder 31, a plurality of baffles 32 are evenly connected along the circumferential interval. The side edge of the baffle 32 away from the fixed cylinder 31 abuts against the inner peripheral wall of the placement groove 11, thereby dividing the storage area into a plurality of storage grooves 33 corresponding to the number of NdFeB magnets 2, ensuring that the NdFeB magnets 2 have a fixed position during the installation process, avoiding the problem of inaccurate position during manual installation. A plurality of installation grooves 41 are evenly spaced along the circumferential interval on the outer peripheral wall of the installation sleeve 4, and the installation grooves 41 extend axially, and an insertion port 411 is provided on the side close to the fixed cylinder 31, and the NdFeB magnet 2 can be placed in the installation groove 41 through the insertion port 411. Each installation groove 41 is also provided with a sliding channel 412 extending in the axial direction on the groove wall, and the sliding channel 412 is connected to the installation groove 41, providing a path for the subsequent pushing of the NdFeB magnet 2. The pressure ring 5 is slidably connected to the outer peripheral wall of the installation sleeve 4, and a number of push blocks 51 are evenly spaced along the circumferential direction on the inner side thereof. The push blocks 51 can be inserted into the installation groove 41 through the sliding channel 412 and are located on the side of the NdFeB magnet 2 away from the fixed cylinder 31. When the pressure ring 5 is pushed, it will drive the push block 51 to move along the sliding channel 412, thereby pushing the NdFeB magnet 2 out of the installation groove 41 through the insertion port 411, and accurately pushing it into the storage groove 33 to complete the installation process.

[0050] In this embodiment, when in use, first, the fixed cylinder 31 in the positioning mechanism 3 is placed in the placement groove 11 of the base 1, and a storage area is formed between the fixed cylinder 31 and the inner peripheral wall of the placement groove 11. The baffles 32 on the positioning mechanism 3 are evenly spaced and connected to the outer peripheral wall of the fixed cylinder 31 along the circumferential direction, and the side of the baffle 32 away from the fixed cylinder 31 abuts against the inner peripheral wall of the placement groove 11, thereby dividing the storage area into a number of storage grooves 33 corresponding to the number of NdFeB magnets 2. Next, the installation sleeve 4 is sleeved on the outside of the fixed cylinder 31, and the installation sleeve 4 is evenly spaced along the circumferential direction. A number of installation grooves 41 are provided on the installation sleeve 4, and the installation grooves 41 extend axially, and each installation groove 41 is provided with an insertion port 411 on the side close to the fixed cylinder 31, and the operator inserts the NdFeB magnets 2 into the corresponding installation grooves 41 one by one through the insertion port 411. The pressure ring 5 is slidably connected to the outer peripheral wall of the installation sleeve 4. The inner side of the pressure ring 5 is evenly spaced along the circumference. The push blocks 51 can be inserted into the corresponding installation groove 41 through the sliding channel 412 and are located on the side of the NdFeB magnet 2 that has been placed away from the fixed cylinder 31. After the NdFeB magnets 2 are placed in the installation grooves 41, the pressure ring 5 is operated to drive the push blocks 51 to move along the sliding channel 412, and the NdFeB magnets 2 are pushed out from the installation grooves 41 through the insertion port 411, and accurately pushed into the storage grooves 33 previously separated by the positioning mechanism 3. Due to the presence of the baffle 32, the NdFeB magnets 2 will be accurately positioned in the corresponding storage grooves 33 without mutual interference or misalignment. Through the tooling of this embodiment, multiple NdFeB magnets 2 can be accurately placed in the placement groove 11 of the base 1 at one time without moving the position of the NdFeB magnets 2 multiple times, thereby greatly improving the installation accuracy and efficiency, and avoiding the risk of collision and breakage that may occur when the NdFeB magnets 2 are directly operated manually, effectively protecting the integrity of the NdFeB magnets 2, and also reducing the possibility of injury to operators.

[0051] Alternatively, if Figure 5 , Figure 6 As shown, a plurality of inserting grooves 311 are formed on the outer peripheral wall of the fixing tube 31 along the circumferential direction. The inserting grooves 311 penetrate the fixing tube 31 along the axial direction. One side of the baffle 32 is inserted into the inserting groove 311 .

[0052] Specifically, a plurality of plug-in grooves 311 are provided on the outer peripheral wall of the fixed cylinder 31 along the circumferential direction, and the plug-in grooves 311 penetrate the entire fixed cylinder 31 along the axial direction of the fixed cylinder 31. The number and position of the plug-in grooves 311 can be adjusted according to actual needs to ensure that the baffle 32 can be evenly distributed on the outer peripheral wall of the fixed cylinder 31. One side of the baffle 32 is in a shape that matches the plug-in groove 311 so that it can be easily inserted into the plug-in groove 311. During the insertion process, the baffle 32 can be fine-tuned by the guidance of the plug-in groove 311 to ensure that it is in close contact with the inner peripheral wall of the placement groove 11.

[0053] In this optional embodiment, the plug-in connection between the plug-in slot 311 and the baffle 32 can ensure a more stable connection between the baffle 32 and the fixing cylinder 31, thereby avoiding the positional displacement of the neodymium iron boron magnet 2 due to the loosening of the baffle 32 during the installation of the neodymium iron boron magnet 2. The plug-in slot 311 makes the removal and replacement of the baffle 32 simpler and faster, without the need for additional tools or complicated operating steps, which is particularly important for scenes where the baffle 32 needs to be replaced frequently, and can greatly improve work efficiency.

[0054] Alternatively, if Figure 5 , Figure 6 , Figure 7 As shown, the positioning mechanism 3 also includes a first threaded rod 34, a second threaded rod 35 and a push rod 36. A first positioning hole 312 and a second positioning hole 313 are provided on the inner circumferential wall of the fixed cylinder 31 near the end of the mounting sleeve 4. The central axes of the first positioning hole 312 and the second positioning hole 313 coincide with and intersect with the central axis of the fixed cylinder 31 at right angles. One end of the first threaded rod 34 is inserted into the first positioning hole 312, and an internal thread 341 is provided on the inner circumferential wall of the other end of the first threaded rod 34. One end of the second threaded rod 35 is inserted into the second positioning hole 313, and an external thread 351 is provided on the outer circumferential wall of the other end of the second threaded rod 35. The internal thread 341 of the first threaded rod 34 is connected with the external thread 351 of the second threaded rod 35. The push rod 36 is inserted into the central through hole 12 of the base 1 from the side of the base 1 away from the mounting sleeve 4 along the central through hole 12 of the base 1, and is detachably connected to the first threaded rod 34 or the second threaded rod 35.

[0055] Specifically, a first positioning hole 312 and a second positioning hole 313 are provided on the inner peripheral wall of the fixed cylinder 31 on a side close to the mounting sleeve 4, and the central axes of the two positioning holes coincide and intersect with the central axis of the fixed cylinder 31 vertically. The first threaded rod 34 and the second threaded rod 35 are respectively inserted into the two positioning holes, and are connected to each other and adjusted in length by threaded connection. The operator connects the first threaded rod 34 and the second threaded rod 35 to the fixed cylinder 31 by rotating the first threaded rod 34 or the second threaded rod 35. The push rod 36 can be inserted into the central through hole 12 of the base 1 from the side of the base 1 away from the mounting sleeve 4, and is detachably connected to the first threaded rod 34 or the second threaded rod 35. The operator can drive the fixed cylinder 31 and the baffle 32 to move back and forth in the direction close to or away from the base 1 by pushing or pulling the push rod 36, so as to complete the placement and removal of the fixed cylinder 31 in the base 1.

[0056] In this optional embodiment, the columnar base 1 is provided with a central through hole 12 at the central axis for mounting the moving shaft in the high-frequency generator. When in use, the push rod 36 is inserted into the central through hole 12 of the base 1 from the side of the base 1 away from the mounting sleeve 4 along the central through hole 12 of the base 1, and is detachably connected to the first threaded rod 34 or the second threaded rod 35, and then the internal thread 341 of the first threaded rod 34 is connected to the external thread 351 of the second threaded rod 35. Then, the second threaded rod 35 is rotated relative to the first threaded rod 34 to move the second threaded rod 35 to the side away from the first threaded rod 34, or the first threaded rod 34 is rotated relative to the second threaded rod 35 to move the first threaded rod 34 to the side away from the second threaded rod 35, so that the ends of the first threaded rod 34 and the second threaded rod 35 that are away from each other are respectively abutted in the first positioning hole 312 and the second positioning hole 313, so that the first threaded rod 34, the second threaded rod 35 and the push rod 36 are connected to the fixed cylinder 31, and then the push rod 36 is pushed to move along the central through hole 12 of the base 1 to the side close to the first threaded rod 34 or the second threaded rod 35, so as to drive the fixed cylinder 31 and the baffle 32 to move out of the base 1. The first threaded rod 34 and the second threaded rod 35 in this embodiment can also be used to position the installation sleeve 4, so that the installation groove 41 on the installation sleeve 4 corresponds to the storage groove 33 at the base 1, which is convenient for the installation of the NdFeB magnet 2.

[0057] Alternatively, if Figure 4 As shown, a plurality of insertion notches 42 are provided on the peripheral wall of the installation sleeve 4 near one end of the fixing tube 31. When the installation sleeve 4 is inserted into the fixing tube 31, the first threaded rod 34 and the second threaded rod 35 are clamped in the insertion notches 42 so that the installation groove 41 corresponds to the storage groove 33.

[0058] Specifically, the number, shape, size and distribution of the plug-in notches 42 can be customized according to actual application requirements. For example, in order to enhance the stability of the connection, multiple plug-in notches 42 can be provided and evenly distributed along the peripheral wall of the mounting sleeve 4. In order to further improve the alignment accuracy, positioning marks or guide structures can be provided on the plug-in notches 42 or related components so as to more accurately find the alignment position during the installation process.

[0059] In this optional embodiment, eight NdFeB magnets 2 need to be placed on the inner circumferential wall of the placement groove 11 of the base 1, and eight baffles 32 are connected to the outer circumferential wall of the fixed cylinder 31, dividing the storage area between the fixed cylinder 31 and the inner circumferential wall of the placement groove 11 into eight storage grooves 33 for placing the eight NdFeB magnets 2. In this embodiment, four installation grooves 41 are evenly spaced along the circumferential direction on the outer circumferential wall of the installation sleeve 4, and the pressure ring 5 pushes the NdFeB magnets 2 in the four installation grooves 41 into the four storage grooves 33 corresponding to the installation grooves 41 at one time, and the installation of the eight NdFeB magnets 2 is completed twice. In this embodiment, two pairs of four plug-in notches 42 are provided on the peripheral wall of the installation sleeve 4 near the fixed cylinder 31. During the first installation, the installation sleeve 4 is moved toward the fixed cylinder 31 so that it is partially inserted into the fixed cylinder 31, and the first threaded rod 34 and the second threaded rod 35 are inserted into one pair of plug-in notches 42. Then, the installation sleeve 4 is continued to be moved toward the fixed cylinder 31 so that the first threaded rod 34 and the second threaded rod 35 are against the bottom of the plug-in notch 42. At this time, the four installation grooves 41 on the installation sleeve 4 correspond to the four storage grooves 33 on the base 1 respectively. Then, the four installation grooves are connected by the pressing ring 5. The NdFeB magnet 2 in 41 is pushed into the four storage slots 33 corresponding to the installation slots 41; during the second installation, the installation sleeve 4 is rotated and moved toward the fixed cylinder 31, and the first threaded rod 34 and the second threaded rod 35 are inserted into another pair of plug-in notches 42 on the installation sleeve 4. At this time, the four installation slots 41 on the installation sleeve 4 correspond to the other four storage slots 33 on the base 1 that do not contain the NdFeB magnet 2. Then, the pressure ring 5 is used to push the NdFeB magnet 2 in the four installation slots 41 into the four storage slots 33 corresponding to the plug-in slots 311, completing the two installations of the NdFeB magnet 2. In this embodiment, the connection between the installation sleeve 4 and the fixed cylinder 31 is more secure through the plug-in notch 42 and the first threaded rod 34 and the second threaded rod 35, reducing the looseness or dislocation caused by vibration or external force. The insertion notch 42 not only plays a snap-in role, but also ensures the precise alignment between the installation slot 41 and the storage slot 33, which is particularly important for application scenarios that require high-precision matching.

[0060] Alternatively, if Figure 4 As shown, the outer circumferential wall of the mounting sleeve 4 is provided with elastic buckles 43 corresponding to the mounting grooves 41 in a one-to-one manner along the circumferential direction. The elastic buckles 43 are located at one end of the corresponding mounting groove 41 close to the fixed cylinder 31. The elastic buckles 43 are used to limit the NdFeB magnet 2 in the mounting groove 41. When the pressure ring 5 pushes the NdFeB magnet 2 out of the mounting groove 41 through the insertion port 411, the elastic buckles 43 are squeezed to deform the elastic buckles 43 to release the limit on the NdFeB magnet 2.

[0061] Specifically, under normal circumstances, the elastic buckle 43 effectively limits the NdFeB magnet 2 in the installation slot 41 due to its own elastic properties, preventing it from falling off or moving due to external vibration or other factors. When the NdFeB magnet 2 needs to be loaded into the storage slot 33, the push block 51 is driven by the pressure ring 5 to move along the sliding channel 412. During the movement, the push block 51 will contact and squeeze the elastic buckle 43. Since the elastic buckle 43 has a certain deformation ability, it will deform under the compression of the push block 51, thereby releasing the limit on the NdFeB magnet 2. The elastic buckle 43 is squeezed and the limit is released, and the NdFeB magnet 2 can move freely from the installation slot 41 and enter the storage slot 33. After completing these operations, remove the pressure on the pressure ring 5, and the elastic buckle 43 will return to its original state due to its own elasticity, ready to limit the next NdFeB magnet 2.

[0062] In this optional embodiment, by providing the elastic buckle 43, it is possible to ensure that the NdFeB magnet 2 remains stable in the installation slot 41 and is not easily dropped or moved due to external factors, thereby improving the stability and reliability of the entire device. When the NdFeB magnet 2 needs to be loaded into the storage slot 33, the limit can be released by a simple external operation (such as the pressure ring 5 driving the push block 51 to move), without the need for a complicated disassembly process, which greatly simplifies maintenance work.

[0063] Alternatively, if Figure 4 As shown, the elastic buckle 43 includes an elastic sheet, one end of which is connected to the mounting sleeve 4, and the other end extends in a direction close to the fixing tube 31 and away from the central axis of the mounting sleeve 4. An avoidance hole 44 is provided on the peripheral wall of the mounting sleeve 4 corresponding to the elastic sheet.

[0064] Specifically, the elastic buckle 43 is composed of an elastic sheet, which extends to the side close to the fixed cylinder 31. When the mounting sleeve 4 is mounted on the fixed cylinder 31, the elastic sheet will abut against one end of the fixed cylinder 31 to limit the movement of the mounting sleeve 4 to the side of the fixed cylinder 31. The end of the elastic sheet close to the fixed cylinder 31 extends to the side away from the central axis of the mounting sleeve 4. When the NdFeB magnet 2 is placed in the mounting groove 41, this extended part of the elastic sheet is blocked at the insertion port 411 of the mounting groove 41, thereby limiting the NdFeB magnet 2 in the mounting groove 41 and preventing the NdFeB magnet 2 from slipping out of the mounting groove 41 through the insertion port 411. A avoidance hole 44 is provided on the peripheral wall of the mounting sleeve 4 corresponding to the elastic sheet. The avoidance hole 44 allows the elastic sheet to be deformed under force without being hindered by the peripheral wall of the mounting sleeve 4, ensuring that the elastic sheet can bend and recover freely, thereby effectively performing the limiting and releasing functions. When the NdFeB magnet 2 needs to be loaded into the storage slot 33, the pressure ring 5 drives the push block 51 to move along the sliding channel 412. During the movement, the push block 51 squeezes the elastic sheet to deform toward the side close to the avoidance hole 44, thereby releasing the obstruction to the insertion port 411 of the installation slot 41, thereby releasing the limit on the NdFeB magnet 2.

[0065] In this optional embodiment, by setting the elastic sheet to extend to the side away from the central axis of the installation sleeve 4, the NdFeB magnet 2 can be effectively limited in the installation groove 41, reducing the risk of the NdFeB magnet 2 falling off or moving due to external factors. The setting of the avoidance hole 44 allows the elastic sheet to bend freely when subjected to external force, thereby more easily releasing the limit on the NdFeB magnet 2, simplifying the operation process and improving work efficiency.

[0066] Alternatively, if Figure 3 , Figure 4 As shown, the mounting sleeve 4 is provided with a plurality of limit grooves 45 at intervals along the circumferential direction, the limit grooves 45 extend along the axial direction of the mounting sleeve 4 and pass through one end of the mounting sleeve 4 close to the fixed tube 31, and the inner side of the pressure ring 5 is evenly spaced along the circumferential direction with a plurality of limit blocks 52, which are inserted into the limit grooves 45.

[0067] Specifically, a plurality of limiting grooves 45 are arranged at intervals along the circumferential direction on the outer peripheral wall of the installation sleeve 4 at one end away from the fixed cylinder 31. The limiting grooves 45 extend along the axial direction of the installation sleeve 4 and penetrate the end of the installation sleeve 4 close to the fixed cylinder 31. The plurality of limiting grooves 45 and the plurality of installation grooves 41 can be arranged alternately along the circumferential direction of the installation sleeve 4. The end of the limiting groove 45 away from the fixed cylinder 31 is a closed end, and the end close to the fixed cylinder 31 is an open end penetrating the installation sleeve 4. The limiting grooves 45 not only provide a connection point between the pressure ring 5 and the installation sleeve 4, but also allow the pressure ring 5 to have a certain range of movement in the axial direction. The inner side of the pressure ring 5 is evenly spaced along the circumferential direction. The limiting blocks 52 correspond to the limiting grooves 45. When the pressure ring 5 is placed on the installation sleeve 4, the closed end of the limiting groove 45 will limit the limiting blocks 52 from sliding off the installation sleeve 4 in the axial direction.

[0068] In this optional embodiment, when the pressure ring 5 is placed on the installation sleeve 4, the limit block 52 will enter the closed end of the limit groove 45 along the guidance of the limit groove 45, and due to the limitation of the closed end of the limit groove 45, the limit block 52 cannot slide off the installation sleeve 4 in the axial direction. In addition, it extends axially toward the side close to the fixed cylinder 31 and passes through the limit groove 45 of the installation sleeve 4, allowing the pressure ring 5 to have a certain range of movement in the axial direction, so that the pressure ring 5 can push the NdFeB magnet 2 out of the installation groove 41 and into the storage groove 33.

[0069] Optionally, anti-slip grooves are provided on the outer peripheral wall of the pressure ring 5 .

[0070] Specifically, a series of anti-slip patterns are provided on the outer wall of the pressing ring 5 . The anti-slip patterns may be raised stripes, dot structures or other shapes to increase the surface roughness of the outer wall of the pressing ring 5 , thereby increasing the force exerted by the user on the pressing ring 5 .

[0071] In this optional embodiment, the anti-slip pattern increases the friction between the pressure ring 5 and the operator, improves the stability of the pressure ring 5 during movement, and reduces the potential safety hazards caused by sliding and colliding with the NdFeB magnet 2.

[0072] A method for using a magnet installation tool for a high-frequency ventilator provided in an embodiment of the present invention is applicable to the magnet installation tool for the high-frequency ventilator, comprising:

[0073] S1: placing the fixed cylinder 31 in the base 1;

[0074] S2: Connect one side of the baffle plate 32 to the insertion groove 311 of the fixed tube 31, and make the side of the baffle plate 32 away from the fixed tube 31 abut against the inner peripheral wall of the placement groove 11;

[0075] S3: squeeze the elastic sheet to move the elastic sheet to the side close to the avoidance hole 44, so that the pressure ring 5 passes through the elastic sheet and is sleeved on the outer periphery of the installation sleeve 4, so that the push block 51 is inserted into the installation groove 41, and the limit block 52 is against the side wall of one end of the limit groove 45;

[0076] S4: placing the NdFeB magnet 2 into the mounting slot 41 through the insertion opening 411;

[0077] S5: Move the installation sleeve 4 toward the side close to the base 1, insert one end of the installation sleeve 4 into the fixing tube 31, and make the installation groove 41 correspond to the storage groove 33;

[0078] S6: Move the pressing ring 5 toward the side close to the storage slot 33, driving the push block 51 to move along the sliding channel 412, so as to push the NdFeB magnet 2 out of the mounting slot 41 through the insertion port 411 and into the storage slot 33;

[0079] S7: After the installation of the NdFeB magnet 2 is completed, the pressure ring 5 is moved to a side away from the fixed cylinder 31, driving the installation sleeve 4 to move out of the fixed cylinder 31;

[0080] S8: Move the fixed cylinder 31 and the baffle 32 toward a side away from the base, so that the fixed cylinder 31 and the baffle 32 are moved out of the base 1.

[0081] Specifically, first, place the fixed cylinder 31 in the base 1, and the fixed cylinder 31 plays a role of positioning and supporting. Then, connect one side of the baffle 32 to the plug-in slot 311 of the fixed cylinder 31, and the side of the baffle 32 away from the fixed cylinder 31 abuts against the inner wall of the placement slot 11. The baffle 32 is used to limit the movement of the NdFeB magnet 2 during the installation process and ensure that the NdFeB magnet 2 can be accurately placed at the designated position in the base 1. By squeezing the elastic sheet, the elastic sheet is moved to the side close to the avoidance hole 44, so that the pressure ring 5 can be passed through the elastic sheet and sleeved on the outer periphery of the installation sleeve 4. At this time, the push block 51 is inserted into the installation slot 41, and the limit block 52 abuts against the closed end of the limit slot 45, ensuring that the pressure ring 5 and the installation sleeve 4 can be stably connected together, and preparing for the subsequent pushing of the NdFeB magnet 2. After that, the NdFeB magnet 2 is placed in the installation groove 41 through the insertion port 411 on the installation sleeve 4, and the installation sleeve 4 is moved to the side close to the base 1, so that one end of the installation sleeve 4 is inserted into the fixed cylinder 31, and the installation groove 41 corresponds to the storage groove 33. Then, the pressure ring 5 is moved to the side close to the storage groove 33, and the push block 51 is driven to move along the sliding channel 412, so that the NdFeB magnet 2 is pushed out from the installation groove 41 through the insertion port 411 and pushed into the storage groove 33. The storage groove 33 corresponds to the placement groove 11 in the base 1, so the NdFeB magnet 2 can be accurately placed in the specified position in the base 1. After the installation of the NdFeB magnet 2 is completed, the pressure ring 5 is moved to the side away from the fixed cylinder 31, and the installation sleeve 4 is driven to move out of the fixed cylinder 31. Finally, the fixed cylinder 31 and the baffle 32 are moved to the side away from the base 1, so that the fixed cylinder 31 and the baffle 32 are moved out of the base 1, and the whole installation process is completed.

[0082] In this optional embodiment, through a series of orderly steps, the installation process of the NdFeB magnet 2 can be efficiently completed, reducing the installation time and labor costs. The method of use of this embodiment simplifies the operation process and reduces the difficulty of operation through a series of standardized steps, so that non-professionals can also easily complete the installation of the NdFeB magnet 2.

[0083] Optionally, step S2 also includes:

[0084] B1: insert the push rod 36 into the central through hole 12 of the base 1 from the side of the base 1 away from the mounting sleeve 4 along the central through hole 12 of the base 1, and detachably connect it with the first threaded rod 34 or the second threaded rod 35, and then connect the internal thread 341 of the first threaded rod 34 with the external thread 351 of the second threaded rod 35;

[0085] B2: Rotate the second threaded rod 35 relative to the first threaded rod 34 to move the second threaded rod 35 away from the first threaded rod 34, or rotate the first threaded rod 34 relative to the second threaded rod 35 to move the first threaded rod 34 away from the second threaded rod 35, so that the ends of the first threaded rod 34 and the second threaded rod 35 away from each other abut against the first positioning hole 312 and the second positioning hole 313 respectively;

[0086] In the above step S5, when one end of the installation sleeve 4 is inserted into the fixing tube 31, the first threaded rod 34 and the second threaded rod 35 are clamped in the insertion notch 42 of the installation sleeve 4, so that the installation groove 41 corresponds to the storage groove 33;

[0087] In the above step S7 , the push rod 36 is moved along the central through hole 12 of the base 1 toward a side close to the first threaded rod 34 or the second threaded rod 35 to drive the fixing tube 31 and the baffle 32 to move out of the base 1 .

[0088] Specifically, the relative distance between the first threaded rod 34 and the second threaded rod 35 can be adjusted by relatively rotating them. When the second threaded rod 35 moves to the side away from the first threaded rod 34, or the first threaded rod 34 moves to the side away from the second threaded rod 35, the ends away from each other will respectively abut against the first positioning hole 312 and the second positioning hole 313, so that the first threaded rod 34, the second threaded rod 35 and the push rod 36 are connected to the fixed cylinder 31, which facilitates the movement of the fixed cylinder 31 relative to the base 1 through the push rod 36. And when one end of the installation sleeve 4 is inserted into the fixed cylinder 31, the first threaded rod 34 and the second threaded rod 35 are clamped in the insertion notch 42 of the installation sleeve 4, ensuring that the positions of the installation slot 41 and the storage slot 33 correspond, and the clamping of the first threaded rod 34 and the second threaded rod 35 provides additional stability to prevent the installation sleeve 4 from moving relative to the base 1 during the installation of the NdFeB magnet 2.

[0089] In this optional embodiment, the push rod 36 drives the fixing cylinder 31 and the baffle 32 to move out of the base 1, which simplifies the disassembly process and improves the disassembly efficiency, thereby shortening the time of the entire installation and disassembly process. In addition, the first threaded rod 34 and the second threaded rod 35 are clamped in the insertion notch 42 of the installation sleeve 4, which not only ensures that the positions of the installation groove 41 and the storage groove 33 correspond, but also improves the accuracy of the installation.

[0090] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
