Description

Technical Field

[0001] The utility model relates to the technical field of magnetic tiles, in particular to a novel magnetic tile. Background Art

[0002] Magnetic tiles are a type of permanent magnet that is mainly used in permanent magnet motors. Unlike electromagnetic motors that generate magnetic potential sources through excitation coils, permanent magnet motors generate constant magnetic potential sources through permanent magnetic materials. Permanent magnetic tiles have many advantages, such as simple motor structure, convenient maintenance, light weight, small size, and low energy consumption. However, the existing magnetic tiles will generate magnetic vibrations during actual use due to the working principle of the motor, which will cause noise pollution. Therefore, a new type of magnetic tile is needed to reduce noise pollution.

[0003] For example, a new type of magnetic tile disclosed in a Chinese utility model patent with a publication number of CN219202882U and an authorization announcement date of June 16, 2023 includes a magnetic tile body, a noise reduction hole, a silencer cover and a silencer chamber, wherein the noise reduction hole is opened on the front side wall of the magnetic tile body and is evenly distributed, the silencer cover is located at the rear side of the inner cavity of the noise reduction hole, and the silencer chamber is opened on the left and right sides of the inside of the silencer cover.

[0004] However, in actual use, although the above-mentioned magnetic tiles eliminate noise through the design of sound insulation boards, elastic parts and sound-absorbing cotton, the noise reduction structures such as sound insulation boards, elastic parts and sound-absorbing cotton are all arranged in the noise reduction holes, and these noise reduction structures cannot be removed and replaced. In this way, when the sound insulation boards, elastic parts and sound-absorbing cotton and other structures are aged, their noise reduction ability will decrease. If they cannot be replaced, the magnetic tiles will generate louder noise when used. At this time, if you want to eliminate the noise, you can only replace the entire magnetic tile, which will cause greater waste. Utility Model Content

[0005] The utility model aims to provide a novel magnetic tile to solve the problem that the existing magnetic tiles generate noise pollution when in use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of magnetic tile, including a magnetic tile body and sound-absorbing cotton, wherein cavities are respectively provided at both ends of the magnetic tile body, sound-absorbing cotton is arranged in the cavities, and multiple first through holes are respectively provided at both sides of the magnetic tile body at the cavities, and a groove is provided at one end of the magnetic tile body in the cavity, and a stopper is slidably connected in the groove, and threaded holes are respectively provided at both ends of the magnetic tile body in the groove, and second through holes are respectively provided at both ends of the stopper, and a fastening screw is movably connected in the second through hole, and the end of the fastening screw passes through the second through hole and is threadedly connected to the threaded hole.

[0007] Preferably, cutting portions are respectively provided at both ends of the magnetic tile body.

[0008] Preferably, the magnetic tile body is provided with mounting holes at both ends of the cutting portion.

[0009] Preferably, the stopper is located at one end of the cavity and is fixedly connected with a pressure block.

[0010] Preferably, the pressing block is slidably connected to the cavity.

[0011] Preferably, the stopper is located at the second through hole and is provided with a receiving groove at one end away from the pressing block, and the receiving groove is adapted to the size of the fastening screw nut.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model eliminates noise through the design of sound-absorbing cotton, and the design of the cavity facilitates the placement of the sound-absorbing cotton. The design of the stopper can block the open end of the cavity to prevent the sound-absorbing cotton from falling out of the cavity. The design of the fastening screw allows the stopper to be stably fixed on the magnetic tile body to ensure that the stopper will not fall out of the groove on the magnetic tile body. The stopper is fixed by the fastening screw so that the stopper can be easily removed. When the stopper is removed, the sound-absorbing cotton in the cavity can be smoothly taken out. In this way, when the sound-absorbing cotton ages and its attraction ability decreases, it can be replaced. The utility model is very practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-5 The utility model provides a technical solution: a new type of magnetic tile, including a magnetic tile body 1 and sound-absorbing cotton 2, cavities 3 are respectively provided at both ends of the magnetic tile body 1, and sound-absorbing cotton 2 is arranged in the cavity 3, a plurality of first through holes 4 are respectively provided at both sides of the magnetic tile body 1 at the cavity 3, a groove 5 is provided at one end of the magnetic tile body 1 located at the cavity 3, a stopper 6 is slidably connected in the groove 5, threaded holes 7 are respectively provided at both ends of the magnetic tile body 1 located at the groove 5, second through holes 8 are respectively provided at both ends of the stopper 6, a fastening screw 9 is movably connected in the second through hole 8, and the end of the fastening screw 9 passes through the second through hole 8 and is threadedly connected to the threaded hole 7,

[0022] In this embodiment, the motor will generate some noise inside during use. These noises are generally transmitted through the air. When the noise passes through the first through hole 4 on the magnetic tile body 1, it will enter the cavity 3. The sound-absorbing cotton 2 arranged in the cavity 3 can absorb the noise, thereby reducing noise pollution. When the sound-absorbing cotton 2 ages and the noise reduction function decreases, the fastening screws 9 at both ends of the block 6 are first removed, so that the block 6 can be taken out from the groove 5 of the magnetic tile body 1. After the block 6 is taken out, the sound-absorbing cotton 2 located in the cavity 3 can be smoothly taken out, so that people can replace the sound-absorbing cotton 2. When the sound-absorbing cotton 2 is replaced, the block 6 can be put back into the groove 5 and fixed with the fastening screws 9, so that the sound-absorbing cotton 2 can be prevented from falling from the cavity 3.

[0023] like Figure 1-2 As shown, cutting portions 10 are respectively provided at both ends of the magnetic tile body 1. In the present embodiment, by providing the cutting portions 10 at both ends of the magnetic tile body 1, the magnetic tile body 1 is made thick in the middle and thin on both sides, which meets the requirement that the air gap in the middle of the magnetic tile body 1 is small and the air gap at the edge is large, thereby allowing the motor to run smoothly, thereby reducing the vibration of the magnetic tile body 1 and further reducing the generation of noise.

[0024] like Figure 1-3 As shown, mounting holes 11 are respectively provided at both ends of the cutting portion 10 of the magnetic tile body 1. In this embodiment, the design of the mounting holes 11 makes it easy for people to mount the magnetic tile body 1 on the motor.

[0025] like Figure 4-5 As shown, the stopper 6 is located at one end of the cavity 3 and is fixedly connected to a pressing block 12 . In this embodiment, the design of the pressing block 12 can compress the sound-absorbing cotton 2 in the cavity 3 , thereby preventing the sound-absorbing cotton 2 from shaking in the cavity 3 .

[0026] like Figure 3-5 As shown, the pressing block 12 is slidably connected to the cavity 3. In this embodiment, by slidably connecting the pressing block 12 to the cavity 3, the pressing block 12 can smoothly enter the cavity 3, thereby smoothly compressing the sound-absorbing cotton 2.

[0027] like Figure 4-5 As shown, the stopper 6 is located at the second through hole 8 and is provided with a receiving groove 13 at one end away from the pressing block 12. The receiving groove 13 is adapted to the size of the nut of the fastening screw 9. In this embodiment, the design of the receiving groove 13 allows the nut of the fastening screw 9 to be embedded in the stopper 6, so that the nut of the fastening screw 9 will not protrude, thereby facilitating the installation and use of the magnetic tile body 1.

[0028] Working principle: When in use, some noise will be generated inside the motor, and these noises are generally transmitted through the air. When the noise passes through the first through hole 4 on the magnetic tile body 1, it will enter the cavity 3. The sound-absorbing cotton 2 arranged in the cavity 3 can absorb the noise, thereby reducing noise pollution. In addition, by arranging cutting parts 10 at both ends of the magnetic tile body 1, the magnetic tile body 1 is thick in the middle and thin on both sides, which meets the requirements of a small air gap in the middle and a large air gap at the edge of the magnetic tile body 1, so that the motor can run smoothly, thereby reducing the vibration of the magnetic tile body 1. The generation of noise is reduced. When the sound-absorbing cotton 2 ages and the noise reduction function decreases, the fastening screws 9 at both ends of the block 6 are first removed, so that the block 6 can be taken out from the groove 5 of the magnetic tile body 1. After the block 6 is taken out, the sound-absorbing cotton 2 in the cavity 3 can be smoothly taken out, which makes it convenient for people to replace the sound-absorbing cotton 2. After the sound-absorbing cotton 2 is replaced, the block 6 can be put back into the groove 5 and fixed with the fastening screws 9. The pressure block 12 is arranged on the block 6 to press the sound-absorbing cotton 2 to prevent it from shaking in the cavity 3.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
