When adjusting the magnetism of the iron core of this desktop magnetizing device, it needs to be rotated. However, the rotating rust will drive the peripheral electromagnetic coil to rotate with it. Obviously, this will cause the wire at the outer end of the electromagnetic coil to break, which obviously poses a great safety hazard.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1-6 , the present utility model provides a technical solution: a double-sided two-end magnetizing device, including a frame 1, an iron core 11 is rotatably installed in the frame 1, an electromagnetic coil 12 is sleeved outside the iron core 11, a first conductive slip ring 15 and a second conductive slip ring 16 are fixedly installed in the frame 1, the first conductive slip ring 15 and the second conductive slip ring 16 are arranged as concentric rings, a storage battery 13 is fixedly installed at the bottom of the inner cavity of the frame 1, connecting wires 131 are fixedly connected between the first conductive slip ring 15 and the second conductive slip ring 16 and the storage battery 13, the first conductive slip piece 151 and the second conductive slip piece 161 are fixedly installed at the head and tail ends of the electromagnetic coil 12, the first conductive slip piece 151 is in mutual contact with the inner wall of the first conductive slip ring 15, the second conductive slip piece 161 is in mutual contact with the inner wall of the second conductive slip piece 161, a magnetizing contact piece 17 is fixedly installed on the upper end surface of the frame 1, and the magnetizing contact piece 17 is in mutual contact with the outer end of the iron core 11.

[0024] Working principle: When adjusting the magnetized magnetic poles, inside the housing 1, the iron core 11 is rotated to select the corresponding magnetic poles at both ends of the iron core 11 and the magnetizing contact piece 17. The rotating iron core 11 and its peripheral electromagnetic coil 12 can drive the first conductive sliding piece 151 and the second conductive sliding piece 161 to rotate inside the first conductive slip ring 15 and the second conductive slip ring 16 respectively. Through the fitting effect between the first conductive sliding piece 151 and the first conductive slip ring 15 and between the second conductive sliding piece 161 and the second conductive slip ring 16, together with the connecting wire 131, the head and tail ends of the electromagnetic coil 12 can always be connected to the positive and negative poles of the storage battery 13;

[0025] Thus, when the circuit between the storage battery 13 and the electromagnetic coil 12 is connected by controlling the outside of the housing 1, the storage battery 13 can supply power to the electromagnetic coil 12, thereby endowing the iron core 11 inside the electromagnetic coil 12 with magnetism. Through the contact effect between the iron core 11 and the magnetizing contact piece 17, the material at the upper end of the magnetizing contact piece 17 can be endowed with magnetism.

[0026] As a further description of the above technical solution: Inside the housing 1, a connecting seat 14 is fixedly installed through a connecting rod. The first conductive slip ring 15 and the second conductive slip ring 16 are fixedly installed at the upper end of the connecting seat 14. A through cavity 172 is opened at the upper end of the housing 1. The magnetizing contact piece 17 is fixedly installed in the through cavity 172. A magnetic conduction piece 171 arranged in an L shape is fixedly installed on the periphery of the magnetizing contact piece 17. The magnetic conduction piece 171 is fixedly connected to the inner wall of the housing 1, and the inner wall of the lower side of the magnetic conduction piece 171 is in contact with the iron core 11.

[0027] Specifically, setting the connecting seat 14 can install and fix the first conductive slip ring 15 and the second conductive slip ring 16. Setting the through cavity 172 can install the magnetizing contact piece 17, enabling an external material to contact the surface of the magnetizing contact piece 17. Fixing the magnetic conduction piece 171 arranged in an L shape on the lower side of the magnetizing contact piece 17 facilitates the rotating iron core 11 to come into contact with the magnetic conduction piece 171 and conduct the magnetism to the surface of the magnetizing contact piece 17.

[0028] As a further description of the above technical solution: A rotating frame 2 is rotatably installed in the frame body 1. The iron core 11 penetrates through and is fixedly installed in the rotating frame 2 along the diameter position. A driven gear 21 is fixedly installed on the upper end surface of the rotating frame 2. A driving gear 22 is rotatably installed at the top end of the inner cavity of the frame body 1. The driven gear 21 and the driving gear 22 are meshed with each other. A first positioning tooth groove 23 is opened at the upper end of the driven gear 21. A second positioning tooth groove 24 is opened at the top of the inner cavity of the frame body 1. The first positioning tooth groove 23 and the second positioning tooth groove 24 are matched in size and position. A positioning tooth block 25 is inserted and installed in the first positioning tooth groove 23 and the second positioning tooth groove 24. A spring 26 is fixedly installed between the lower end of the positioning tooth block 25 and the bottom of the inner cavity of the first positioning tooth groove 23. A through hole 27 is opened at the upper end of the second positioning tooth groove 24. A movable rod 28 inserted into the through hole 27 is fixedly installed at the upper end of the positioning tooth block 25.

[0029] Specifically, by setting the rotating frame 2, the iron core 11 can be fixed. When the iron core 11 needs to be rotated, the positioning tooth block 25 is pressed downward into the first positioning tooth groove 23 through the movable rod 28, so that the positioning tooth block 25 is separated from the second positioning tooth groove 24, thereby releasing the limiting effect on the movable rod 28 and facilitating the rotation of the movable rod 28. The rotating movable rod 28 can drive the rotating frame 2 to rotate in the frame body 1 and drive the iron core 11 to rotate through the plug-in connection between it and the first positioning tooth groove 23 and the meshing connection between the driven gear 21 and the driving gear 22, so that the corresponding outer end of the iron core 11 contacts the magnetizing contact piece 17. Subsequently, when the movable rod 28 is released, under the action of the spring 26 restoring deformation, the positioning tooth block 25 can be driven to reset upward, so that the positioning tooth block 25 is re-inserted into the first positioning tooth groove 23 and the second positioning tooth groove 24, and the driving gear 22 can be positioned, and then the driven gear 21 and the frame body 1 can be positioned, achieving the effect of positioning the iron core 11 and avoiding the deviation at the contact between the iron core 11 and the magnetizing contact piece 17.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
