Description

Technical Field

[0001] This utility model specifically relates to a fan motor easy-to-disassemble structure. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Existing motors are all equipped with an outer casing to protect the various electronic components inside. However, most existing motor casings are assembled and fixed by welding or multiple bolts. Welding makes it impossible to disassemble the motor casing, while multiple bolts require tedious tightening during installation or removal. These connection methods make it inconvenient to disassemble the motor casing, which makes it difficult to repair the internal electronic components when the motor is damaged. This increases the difficulty of motor repair and reduces the practicality of the motor.

[0003] Therefore, it is necessary to provide a fan motor detachable structure to improve the above-mentioned problems. Utility Model Content

[0004] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a fan motor easy-to-disassemble structure.

[0005] A fan motor easy-to-disassemble structure includes a motor housing, which comprises an upper housing and a lower housing. One end of the upper housing has a first flange protruding outward along its edge contour. The first flange is circumferentially spaced with several first limiting blocks, which are elastically extendable and protrude outward from the outer side of the first flange. A first retaining groove is recessed on the first limiting block on the side away from the lower housing. One end of the lower housing has a second flange protruding outward along its edge contour, capable of sealingly abutting against the first flange. A collar movably sleeved on the lower housing is capable of moving closer to or further away from the upper housing. The collar is circumferentially spaced with several connecting rings. Several first limiting blocks are correspondingly disposed inside the connecting rings, and the connecting rings can move with the collar and abut against the first retaining groove, causing the first flange and the second flange to fit tightly together. The lower housing is provided with a driving member capable of driving the collar to move away from the upper housing.

[0006] In one embodiment, the driving component includes a driving knob, a connecting plate protruding from one side of the lower housing, a first guide shaft connecting the connecting plate and the second flange, a collar movably sleeved on the first guide shaft, the driving knob being threadedly inserted into the connecting plate, and one end of the driving knob passing through the collar and having a second limiting block provided thereon, the second limiting block being able to move with the threaded movement of the driving knob to abut and drive the collar to move away from the upper housing.

[0007] In one embodiment, the driving member further includes a locking member disposed on the connecting plate that can lock the rotation of the driving knob.

[0008] In one embodiment, the locking member includes a locking element and a first spring. A groove is concentrically recessed on one side of the drive knob. A plurality of second slots are evenly distributed along the circumference of the sidewall of the groove. The locking element is annular in shape and movably sleeved on the drive knob. A plurality of second guide shafts are spaced apart on one side of the locking element. The second guide shafts are inserted into the connecting plate. The first spring abuts between the locking element and the connecting plate. The locking element can be fitted into the groove. A plurality of protruding teeth are evenly distributed along the circumference of the locking element. The plurality of protruding teeth are engaged with the plurality of second slots one by one.

[0009] In one embodiment, the first flange is provided with a plurality of positioning holes spaced apart, and the second flange is provided with a plurality of positioning posts spaced apart, the positioning posts being inserted into the positioning holes one by one in a corresponding manner.

[0010] In one embodiment, the first flange is provided with a plurality of connecting seats at circumferential intervals, and the connecting seats have a guide groove recessed on the side away from the upper housing. The first limiting block is telescopically movably disposed in the guide groove, and a second spring abuts between the bottom wall of the guide groove and the first limiting block.

[0011] In one embodiment, the connector is detachably connected to the first flange by screws.

[0012] In summary, the advantages of this utility model over the prior art are:

[0013] This invention utilizes the elastic telescopic movement of the first limiting block in the first flange to allow the first limiting block to be pressed and extended to the inner side of the connecting ring of the collar when the first flange of the upper shell and the second flange of the lower shell are relatively close and abutting. Then, the driving component drives the collar in the lower shell to move away from the upper shell, and the connecting ring moves with the collar and abuts against the first slot in the first limiting block. Thus, the connecting ring abuts against the first limiting block, so that the first flange of the upper shell and the second flange of the lower shell are tightly fitted and installed. When the connecting ring abuts against the first slot, the first limiting block cannot telescopically move relative to the first flange, thus achieving a fixed connection between the upper and lower shells. When disassembly is required, it is only necessary to release the driving component from the collar. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1 to 5 The present invention preferably provides a fan motor detachable structure, including a motor housing, the motor housing including an upper housing 1 and a lower housing 2. One end of the upper housing 1 has a first flange 3 protruding outward along its edge contour. The first flange 3 is provided with a plurality of first limiting blocks 4 spaced circumferentially along its circumference. The first limiting blocks 4 are elastically extendable and protrude outward from the outer side of the first flange 3. A first slot 5 is recessed on the first limiting block 4 on the side away from the lower housing 2. One end of the lower housing 2 has a fan motor detachable structure. The second flange 6 is sealed and abuts against the first flange 3. The lower housing 2 is movably sleeved with a collar 7 that can move closer to or further away from the upper housing 1. The collar 7 is provided with a plurality of connecting rings 8 at intervals along the circumference. A plurality of first limiting blocks 4 are correspondingly arranged inside the plurality of connecting rings 8. The connecting rings 8 can move with the collar 7 and abut against the first slot 5, so that the first flange 3 and the second flange 6 are tightly fitted. The lower housing 2 is provided with a driving member 9 that can drive the collar 7 to move away from the upper housing 1.

[0021] Specifically, through the elastic extension and retraction of the first limiting block in the first flange, when the first flange of the upper shell and the second flange of the lower shell are relatively close to each other during installation, the first limiting block can be pressed and extended to the inner side of the connecting ring of the collar. Then, the driving component drives the collar in the lower shell to move away from the upper shell. As a result, the connecting ring moves with the collar and is pressed against the first slot in the first limiting block. Thus, the connecting ring presses against the first limiting block, so that the first flange of the upper shell and the second flange of the lower shell are tightly fitted and installed. When the connecting ring is pressed against the first slot, the first limiting block cannot extend or retract relative to the first flange, thus achieving a fixed connection between the upper shell and the lower shell. When disassembly is required, it is only necessary to release the driving component from driving the collar.

[0022] Furthermore, the driving component 9 includes a driving knob 91, a connecting plate 92 protruding from one side of the lower housing 2, a first guide shaft 93 connecting the connecting plate 92 and the second flange 6, the collar 7 being movably sleeved on the first guide shaft 93, the driving knob 91 being threadedly inserted into the connecting plate 92, and one end of the driving knob 91 passing through the collar 7 and having a second limiting block 99, the second limiting block 99 being able to abut against and drive the collar 7 to move away from the upper housing 1 as the driving knob 91 moves threadedly.

[0023] Specifically, the user manually rotates the drive knob to move it relative to the thread of the connecting plate, which in turn moves the second limit block on the drive knob and pushes the collar away from the upper housing. As a result, the connecting ring on the collar moves and is pressed against the first slot.

[0024] Furthermore, the driving component 9 also includes a locking component 10 disposed on the connecting plate 92 to lock the rotation of the driving knob 91. This locking component ensures that the connecting ring remains in a state of contact with the first slot, preventing the connecting ring from disengaging from the first slot due to loosening of the driving knob, thus achieving a secure connection between the upper and lower housings.

[0025] Furthermore, the locking member 10 includes a locking element 11 and a first spring 12. A groove 13 is concentrically recessed on one side of the drive knob 91. A plurality of second slots 14 are evenly distributed along the circumference of the sidewall of the groove 13. The locking element 11 is annular in shape and movably sleeved on the drive knob 91. A plurality of second guide shafts 15 are spaced apart on one side of the locking element 11. The second guide shafts 15 are inserted into the connecting plate 92. The first spring 12 abuts between the locking element 11 and the connecting plate 92. The locking element 11 can be fitted into the groove 13. A plurality of protruding teeth 101 are evenly distributed along the circumference of the locking element 11. The plurality of protruding teeth 101 are correspondingly engaged with the plurality of second slots 14.

[0026] Specifically, the locking component, through the cooperation of the second guide shaft and the first spring, allows the locking component to move relatively closer to or further away from the drive knob. When the locking component moves relatively closer to the drive knob, the protruding teeth on the locking component can engage in the second slot of the drive knob, thereby locking and fixing the drive knob relative to the connecting plate and preventing the drive knob from loosening. When the locking component moves relatively away from the drive knob, the protruding teeth on the locking component can disengage from the second slot of the drive knob, thereby restoring the drive knob to a rotatable connection state relative to the connecting plate.

[0027] Furthermore, the first flange 3 has a plurality of positioning holes 17 spaced through it, and the second flange 6 has a plurality of positioning posts 16 spaced apart. The positioning posts 16 are inserted into the positioning holes 17 in a one-to-one correspondence. Thus, the positioning posts and positioning holes cooperate to facilitate the alignment and connection between the upper and lower housings.

[0028] Furthermore, the first flange 3 is provided with a plurality of connecting seats 18 spaced apart along its circumference. Each connecting seat 18 has a recessed guide groove 19 on the side furthest from the upper housing 1. The first limiting block 4 is telescopically movably disposed within the guide groove 19. A second spring 20 abuts against the bottom wall of the guide groove 19 and the first limiting block 4. Thus, through the limiting and guiding action of the guide groove and the elastic force of the second spring, the first limiting block can telescopically move within the guide groove, and the first limiting block can elastically extend and protrude outwards from the outer side of the first flange.

[0029] Furthermore, the connecting seat 18 is detachably connected to the first flange 3 by screws. This facilitates disassembly, replacement, and maintenance should the first limiting block be damaged.

[0030] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
