Description

Technical Field

[0001] This utility model relates to the field of magnet-related technology, and in particular to a magnetically stable magnet structure. Background Technology

[0002] Permanent magnets are becoming increasingly important due to their applications in a wide range of industrial and consumer products. They are widely used in electric motors, generators, sensors, speakers, hard disk drive read / write heads, electric vehicles, and many other modern technologies. However, the poor magnetic stability of these magnets in high-temperature, strong magnetic field, or chemically corrosive environments limits their use in a wider range of applications. Particularly in high-temperature applications, conventional permanent magnets are susceptible to thermal demagnetization, leading to performance degradation. Utility Model Content

[0003] This invention aims to overcome the shortcomings of existing technologies in terms of the poor stability of magnets operating for extended periods in high-temperature environments. It provides a magnetically stable magnet structure that provides thermal insulation protection to improve the stability of the magnet.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A magnetically stable magnet structure includes a magnet body, a placement frame, a heat insulation frame, a sealing plate, and a telescopic assembly. The placement frame has an opening at its lower end and is placed inside and connected to the heat insulation frame. The sealing plate is installed at one end of the opening of the placement frame and is slidably connected to the heat insulation frame. The telescopic assembly is installed inside the placement frame, with one end connected to the placement frame and the other end connected to the magnet body. The magnet body is placed inside the placement frame.

[0006] The magnet body is placed inside the placement frame, and the telescopic component is installed on the bottom surface of the placement frame. The telescopic component can be used to extend the magnet body out of the placement frame for use. Both the placement frame and the magnet body are placed inside the heat insulation frame, and there is a certain gap between the placement frame and the heat insulation frame. The heat insulation frame isolates the magnet body from the high-temperature environment, reducing the impact of the high-temperature environment on the magnet body. A sealing plate is installed at one end of the opening of the placement frame. The sealing plate is slidably connected to the heat insulation frame, which can close the magnet body when not in use and open the placement frame to allow the magnet body to extend when in use. This can further improve the heat insulation capacity and achieve the purpose of heat insulation protection for the magnet to improve the stability of the magnet.

[0007] Preferably, one end of the heat insulation frame is open, and a connecting ring is provided at one end of the open end of the heat insulation frame. The placement frame is placed inside the heat insulation frame, the outer side of the connecting ring is connected to the heat insulation frame, and the inner side of the connecting ring is connected to one end of the open end of the placement frame. One end of the open end of the heat insulation frame and one end of the open end of the placement frame are on the same plane. The heat insulation frame and the placement frame are connected by the connecting ring, forming a sealed space between the placement frame and the heat insulation frame. Inert gas can be filled into the sealed space to improve the heat insulation performance of the heat insulation frame. This design can improve the heat insulation performance.

[0008] Preferably, the sealing plate corresponds to the heat insulation frame. Guide plates are installed on both sides of the heat insulation frame. The guide plates have an L-shaped cross-section and guide grooves, each with an L-shaped cross-section. Connecting posts are provided on both sides of the sealing plate. One end of each connecting post is connected to the sealing plate, and the other end is placed within the guide groove. The sealing plate is slidably connected to the guide plates through the cooperation of the connecting posts and guide grooves. The shape of the sealing plate corresponds to one end of the opening of the heat insulation frame, allowing for the closure of that opening. L-shaped guide plates are installed on both sides of the heat insulation frame, each with a corresponding guide groove. Connecting posts are installed on both sides of the sealing plate, with one end placed within the guide groove. These connecting posts can move under the guidance of the guide groove, pushing the sealing plate until it fits against one side of the heat insulation frame, thus opening the opening of the sealing plate. This design facilitates opening the sealing plate.

[0009] Preferably, an mounting block is installed at the end of the sealing plate away from the guide plate. A rotating shaft is mounted on the mounting block, and a screw is mounted on the rotating shaft. A fixing block is installed on one side of the heat insulation frame, and a fixing groove is installed on the fixing block. One end of the screw passes through the fixing groove and is positioned on the other side of the fixing block. A fixing nut is installed at the end of the screw that passes through the fixing groove, and the fixing nut is threadedly connected to the screw. With the sealing plate closed, rotating the rotating shaft rotates the screw into the fixing groove of the fixing block. After the screw is placed in the fixing groove, rotating the fixing nut on the screw presses against the fixing block, thus fixing the sealing plate to the heat insulation frame. This design facilitates the fixing of the sealing plate.

[0010] Preferably, the sealing plate has an insertion hole on the side near the guide plate, a sliding block is installed on the upper surface of the heat insulation frame, a slider is provided on the heat insulation frame, and the slider has a sliding groove. The slider is slidably connected to the heat insulation frame through the cooperation of the sliding block and the sliding groove. An insertion block is installed on one side of the slider, and the insertion block matches the insertion hole. A push block is installed on the slider. The sealing plate has an insertion hole at the end near the guide plate. When the sealing plate moves to fit against the side of the heat insulation frame, the insertion hole is positioned at the top and corresponds to the insertion block on the top surface of the heat insulation frame. Pushing the push block moves the sliding block along the sliding block, inserting the insertion block into the insertion hole, and fixing the sealing plate to the side, preventing the guide plate from slipping and affecting the use of the magnet body. This design can prevent the guide plate from slipping.

[0011] Preferably, the telescopic assembly includes a first connecting block, a second connecting block, and a first motor. The first connecting block is installed on the inner bottom surface of the placement frame, and the second connecting block is installed on the magnet body. Rotating rods are installed on both sides of the second connecting block. Each rotating rod includes a connecting rod and a pressing block. There are two connecting rods connected in sequence, and the connection point of the two connecting rods is installed on the pressing block. The connecting rod is rotatably connected to the pressing block. One end of the rotating rod is rotatably connected to the first connecting block, and the other end of the rotating rod is rotatably connected to the second connecting block. A lead screw is provided on the pressing block. The lead screw passes through the pressing blocks on both sides in sequence. The lead screw is rotatably connected to one of the pressing blocks and threadedly connected to the other pressing block. The first motor is installed on one of the pressing blocks rotatably connected to the lead screw. A gear is installed on the motor shaft of the first motor. A gear is installed on the end of the lead screw near the first motor. The gear meshes with the gear, and one side of the gear is in contact with the pressing block. The telescopic assembly connects the magnet body to the inner bottom surface of the placement frame. When the magnet assembly needs to be pushed out of the placement frame, motor one is activated, driving the lead screw to rotate through the meshing of gear one and gear two. Since the lead screw is rotatably connected to a pressing block and threaded to another, the lead screw will press and drive the two pressing blocks to move towards each other. Because the pressing block closest to gear two is rotatably connected to the lead screw, this pressing block is always in contact with gear two. The opposing movement of the pressing blocks will cause the included angle between the two rotating rods on both sides to gradually increase. The gradually increasing included angle between the two connecting rods of the rotating rod will apply pressure to the connecting blocks one and two on both sides. Connecting block one is fixed, so the movement of connecting block two will drive the magnet body to be pushed out of the placement frame to work. This design facilitates the pushing out of the magnet body.

[0012] The beneficial effects of this utility model are: it provides heat insulation protection for the magnet to improve its stability, which can improve the heat insulation performance, facilitates opening and fixing of the sealing plate, prevents the guide plate from slipping, and facilitates the ejection of the magnet body.

[0024] An installation block 42 is installed on the end of the closed plate 4 away from the guide plate 32. A rotating shaft 43 is installed on the installation block 42. A screw 44 is installed on the rotating shaft 43. A fixing block 34 is installed on one side of the heat insulation frame 3. A fixing groove 35 is installed on the fixing block 34. One end of the screw 44 passes through the fixing groove 35 and is placed on the other side of the fixing block 34. A fixing nut 45 is installed on the end of the screw 44 that passes through the fixing groove 35. The fixing nut 45 is threadedly connected to the screw 44.

[0025] like Figure 6 As shown, the sealing plate 4 has an insertion hole 46 on the side near the guide plate 32. A sliding block 36 is installed on the upper surface of the heat insulation frame 3. A slider 6 is provided on the heat insulation frame 3. A sliding groove 61 is provided on the slider 6.

An insertion block 62 is installed on one side of the slider 6. The insertion block 62 matches the insertion hole 46. A push block 63 is installed on the slider 6.

[0026] like Figure 5 As shown, the telescopic assembly 5 includes a first connecting block 51, a second connecting block 52, and a first motor 54. The first connecting block 51 is installed on the inner bottom surface of the placement frame 2, and the second connecting block 52 is installed on the magnet body 1. Rotating rods 53 are installed on both sides of the second connecting block 52. Each rotating rod 53 includes a connecting rod 55 and a pressing block 56. Two connecting rods 55 are provided and connected sequentially. The connection point of the two connecting rods 55 is installed on the pressing block 56, and the connecting rod 55 is rotatably connected to the pressing block 56. One end of the rotating rod 53 is rotatably connected to the first connecting block 51, and the other end of the rotating rod 53 is rotatably connected to the first connecting block 51. Connecting block 2 52 is rotatably connected. The extrusion block 56 is provided with a lead screw 57. The lead screw 57 passes through the extrusion blocks 56 on both sides in sequence. The lead screw 57 is rotatably connected to one of the extrusion blocks 56 and threadedly connected to the other extrusion block 56. Motor 1 54 is installed on one of the extrusion blocks 56 rotatably connected to the lead screw 57. Gear 1 58 is installed on the motor shaft of motor 1 54. Gear 2 59 is installed at the end of the lead screw 57 near motor 1 54. Gear 2 59 meshes with gear 1 58. One side of gear 2 59 is in contact with extrusion block 56.

[0027] During installation, the placement frame 2 is installed inside the insulation frame 3, and inert gas is filled between the placement frame 2 and the insulation frame 3 to improve the insulation performance. When the magnet body 1 needs to be used, the fixing nut 45 is rotated to contact the fixing nut 45 and fix the fixing block 34.

The gradually increasing included angle between the two connecting rods 55 of the rotating rod 53 will apply pressure to the connecting blocks 1 51 and 2 52 on both sides. The connecting block 1 51 is fixed, so the movement of the connecting block 2 52 will drive the magnet body 1 to be squeezed out of the placement frame 2 for operation.
