Technical Field

[0001] The utility model relates to the technical field of magnetic tile installation, and particularly relates to an anti-vibration bracket for magnetic tiles. Background Art

[0002] Magnetic tiles are important magnetic components and are widely used in multiple fields. Magnetic tiles are formed by molding and sintering hard magnetic ferrite materials. Strontium ferrite (SrFe12O19) is a common magnetic tile material. It is in the form of black powder and is mainly used as the stator of a permanent magnet motor. Magnetic tiles have high magnetic permeability, high saturation magnetic flux density, and relatively high wear resistance.

[0003] In the prior art, the installation operation is only carried out by fitting the inner wall of the motor housing with the outer surface of the magnetic tile, and then using U-shaped iron wires to hold two magnetic tiles against each other. This installation structure is prone to the relaxation of the magnetic tiles due to the aging of the U-shaped iron wires, and the installation method of the U-shaped iron wires has a poor fixing effect on the magnetic tiles. After severe vibration, the iron wires are prone to bending, affecting the installation stability of the magnetic tiles. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide an anti-vibration bracket for magnetic tiles, which can firmly position the magnetic tiles through the positioning strip and the locking ring, avoiding the situation of relaxation, so as to solve the problems put forward in the above background art.

[0005] The utility model is realized by the following technical solutions: an anti-vibration bracket for magnetic tiles, including a motor housing and multiple magnetic tiles. The magnetic tiles are evenly distributed in a ring structure inside the motor housing. L-shaped grooves are provided on both sides of the magnetic tiles in the length direction. The L-shaped grooves on adjacent magnetic tiles are combined to form a "T"-shaped positioning groove. A positioning strip for circumferentially positioning the magnetic tiles is installed on the inner circumferential surface of the motor housing corresponding to the positioning groove. Locking rings for pressing and fixing both ends of the magnetic tiles are installed in the openings at both ends of the motor housing.

[0006] As a preferred technical solution, external threads are provided on the outer circumferential surfaces of the locking rings, internal threads are provided on the inner wall surfaces of the openings at both ends of the motor housing, and the locking rings are engaged with the internal threads on the motor housing through the external threads. Multiple slots are provided on the outer side surfaces of the locking rings.

[0007] As a preferred technical solution, multiple grooves are arranged in a ring structure on the inner wall surfaces of the openings at both ends of the motor housing. Positioning blocks are arranged in the grooves. One end of each positioning block extends to the outside and is in contact with the outer side surface of the locking ring. Multiple compression springs are installed at the other end of each positioning block, and the other ends of the compression springs are installed on the inner wall surfaces of the grooves.

[0008] As a preferred technical solution, the cross sections of the positioning strips are all arranged in a "T"-shaped structure, and the outer wall surfaces of the positioning strips are in contact with the inner wall surfaces of the L-shaped grooves.

[0009] As a preferred technical solution, the inner sides of the positioning strips are flush with the inner sides of the magnetic tiles, and the outer sides of the magnetic tiles are in contact with the inner circumferential surface of the motor housing.

[0010] As a preferred technical solution, both the locking ring and the positioning strips are made of metal materials.

[0011] As a preferred technical solution, the width of the locking ring is smaller than the width of the magnetic tile.

[0012] The beneficial effects of the present utility model are as follows: The structure of the present utility model is simple. Through the positioning strips, the magnetic tiles can be independently and evenly distributed and circumferentially positioned, while the axially inwardly approaching locking ring can axially position the magnetic tiles to ensure the stability of the installation and avoid loosening caused by vibration or aging.

[0018] The following will describe in detail the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0019] All the features disclosed in this specification, or all the steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0021] As Figure 1 、 Figure 2 and Figure 3 shown, a vibration-resistant bracket for magnetic tiles of the present utility model includes a motor housing 1 and multiple magnetic tiles 2. The magnetic tiles 2 are evenly distributed in a circular structure inside the motor housing 1. L-shaped grooves 7 are provided on both sides in the length direction of the magnetic tiles 2. The L-shaped grooves 7 on adjacent magnetic tiles 2 are combined to form a "T"-shaped positioning groove. A positioning strip 3 for circumferentially positioning the magnetic tiles 2 is installed on the inner circumferential surface of the motor housing 1 opposite to the positioning groove. Locking rings 4 for pressing and fixing both ends of the magnetic tiles 2 are installed in the openings at both ends of the motor housing 1.

[0022] In this embodiment, external threads are provided on the outer circumferential surfaces of the locking rings 4, and internal threads are provided on the inner wall surfaces of the openings at both ends of the motor housing 1. The locking rings 4 are engaged and connected to the internal threads on the motor housing 1 through the external threads. Multiple slots 5 are provided on the outer side surfaces of the locking rings 4.

[0023] In this embodiment, multiple grooves are provided in a circular structure on the inner wall surfaces of the openings at both ends of the motor housing 1. Positioning blocks 6 are provided in the grooves. One end of each positioning block 6 extends to the outside and is in contact with the outer side surface of the locking ring 4, and multiple compression springs are installed at the other end. The other ends of the compression springs are installed on the inner wall surfaces of the grooves.

[0024] In this embodiment, the cross-section of the positioning strip 3 is provided in a "T"-shaped structure, and the outer wall surface of the positioning strip 3 is in contact with the inner wall surface of the L-shaped groove 7.

[0025] In this embodiment, the inner side surfaces of the positioning strips 3 are flush with the inner side surfaces of the magnetic tiles 2, and the outer side surfaces of the magnetic tiles 2 are in contact with the inner circumferential surface of the motor housing 1, so as to position the magnetic tiles front and back, avoid loosening of the magnetic tiles, and increase the installation stability.

[0026] In this embodiment, both the locking rings 4 and the positioning strips 3 are made of metal materials, which increases the firmness and service life and can better position the magnetic tiles.

[0027] In this embodiment, the width of the locking ring 4 is smaller than the width of the magnetic tile 2, so that the locking ring does not completely cover the magnetic tile and the positioning strip. Thus, the installation accuracy of the magnetic tile can be known through the flatness between the magnetic tile and the positioning strip, and the situation where the length of the magnetic tile does not meet the requirements can be avoided.

[0028] During installation, the magnetic tile can be directly inserted between adjacent positioning strips along the inner wall of the motor housing, and the L-shaped grooves on both sides of the magnetic tile can be set against the positioning strips. The positioning strips can position the magnetic tile circumference and also position it inside and outside to prevent it from falling out.

[0029] After the magnetic tile is assembled, the locking ring can be threadedly connected to the inside of the motor housing. The magnetic tile can be clamped and positioned in the middle through two inwardly approaching locking rings until the inner side of the locking ring is against the two end surfaces of the positioning strip. At this time, multiple magnetic tiles can be centrally positioned to ensure the accuracy and stability of the installation and avoid looseness caused by aging or vibration.

[0030] Among them, after the locking ring is rotated into place, the positioning block can be pushed outward partially through the rebound of the compression spring, and the positioning block can abut against the outer side surface of the locking ring, thereby positioning the locking ring and avoiding loosening caused by the locking ring's own rotation.

[0031] On the contrary, when disassembling, any metal rod can be prepared, one end of the metal rod can be inserted into the slot, and the locking ring can be rotated through the metal plate. After the locking ring is removed from the motor housing, the magnetic tile can be directly taken out axially, which greatly facilitates installation and disassembly.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
