[0023] Please refer to Figures 1-5 As shown, the present utility model provides an arc-shaped sliding snap-on neodymium iron boron magnet unit, which includes a housing assembly 1 and a neodymium iron boron magnet 2. The neodymium iron boron magnet 2 is inserted into the inner wall of the housing assembly 1. A cross screw 3 is inserted into the outer wall of the housing assembly 1, and a circular block 4 is provided below the cross screw 3. A spring 5 is provided below the circular block 4, and the top of a metal ball 6 is provided below the spring 5. The bottom of the metal ball 6 is clamped inside the upper part of the neodymium iron boron magnet 2.

[0024] In this embodiment, a plurality of placement groove parts 104 are formed on the inner wall of the housing assembly 1, and the plurality of placement groove parts 104 equally divide the inner wall of the housing assembly 1.

[0025] Furthermore, convex parts 101 are fixedly connected to both inner walls of the placement groove part 104, and the convex parts 101 are symmetrical to each other.

[0026] Furthermore, groove parts 201 are formed on both sides of the neodymium iron boron magnet 2, and the neodymium iron boron magnet 2 is inserted and slidably connected into the placement groove part 104. At the same time, the convex parts 101 are inserted into the groove parts 201.

[0027] Among them, the neodymium iron boron magnet 2 is inserted into the placement groove part 104 in the housing assembly 1. By using the cooperation of the convex part 101 and the groove part 201, the neodymium iron boron magnet 2 is fixed in the placement groove part 104, and both sides of the neodymium iron boron magnet 2 can be pushed out.

[0028] A plurality of cylindrical holes 102 are formed in the outer wall of the housing assembly 1, and the plurality of cylindrical holes 102 equally divide the outer wall of the housing assembly 1 in a circle.

[0029] Furthermore, an internal thread blocking block part 103 is fixedly connected above the cylindrical hole 102, and the center of the internal thread blocking block part 103 is inserted and threadedly connected with the cross screw 3.

[0030] Furthermore, the bottom of the cross screw 3 is fixedly connected to the circular block 4, and the bottom of the circular block 4 is fixedly connected to the top of the spring 5.

[0031] After the cross screw 3 and the internal thread blocking block part 103 are matched in the housing assembly 1, the cross screw 3 can rotate with the internal thread blocking block part 103. In this way, when the cross screw 3 rotates, the spring 5 can be compressed or relaxed.

[0032] Further, the bottom of the spring 5 is fixedly connected to the top of the metal ball 6, and the lower part of the metal ball 6 passes through the bottom of the cylindrical hole 102. A ball groove portion 202 is formed at the top of the neodymium iron boron magnet 2, and the lower part of the metal ball 6 is clamped into the ball groove portion 202.

[0033] The lower part of the metal ball 6 provided below the spring 5 passes through the cylindrical hole 102. After the neodymium iron boron magnet 2 is inserted into the placement groove portion 104, the lower part of the metal ball 6 is inserted into the ball groove portion 202 above the neodymium iron boron magnet 2, so that the neodymium iron boron magnet 2 is limited and fixed.

[0034] Working principle:

[0035] A plurality of placement groove portions 104 are formed on the inner wall of the outer shell assembly 1, and the neodymium iron boron magnets 2 can be inserted from both sides into the placement groove portions 104. At the same time, the convex portions 101 provided in the placement groove portions 104 cooperate with the groove portions 201 provided on both sides of the neodymium iron boron magnets 2, so that a plurality of neodymium iron boron magnets 2 are arranged on the inner wall of the outer shell assembly 1 as a whole unit. A cross screw 3 is inserted into the cylindrical hole 102 inside the outer wall of the outer shell assembly 1, and the cross screw 3 cooperates with the internal thread blocking portion 103 in the cylindrical hole 102. In this way, under the action of the external force of the cross screw 3, it can rotate depending on the internal thread blocking portion 103. A circular block 4, a spring 5 and a metal ball 6 are sequentially arranged below the cross screw 3. By rotating the cross screw 3, the compression degree of the spring 5 on the metal ball 6 can be adjusted. When the neodymium iron boron magnet 2 is inserted into the placement groove portion 104, first, the metal ball 6 is pressed into the cylindrical hole 102, and then after the lower part of the metal ball 6 is clamped into the ball groove portion 202, the installation of the neodymium iron boron magnet 2 is completed. If you want to remove the neodymium iron boron magnet 2, you only need to push it out forcefully from either side.
