Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] Please refer to Figures 1 to 5 , the present invention provides a technical solution:

[0030] A micro coreless motor that is easy to disassemble, including a machine shell 1, an end cover 2 is provided at one end of the machine shell 1, and a quick disassembly and assembly mechanism 3 is provided between the machine shell 1 and the end cover 2. The quick disassembly and assembly mechanism 3 includes a locking assembly 31 and a locking component 32;

[0031] The locking assembly 31 includes an installation ring 311, a locking block 312, a slot 313, and a locking groove 314. The installation ring 311 is fixedly connected to the inner wall of the housing 1. Four locking blocks 312 are fixedly connected to the bottom surface of the end cover 2. The locking blocks 312 are L-shaped. Four slots 313 are formed in the side wall of the installation ring 311. The slots 313 are movably connected to the locking blocks 312. The locking groove 314 is formed in the side wall at the bottom of the slot 313. The bottom of the locking block 312 is movably connected to the locking groove 314.

[0032] Specifically, as Figure 1 shown, a first identifier 5 is provided on the top surface of the end cover 2, and a second identifier 6 is provided on the side wall of the housing 1.

[0033] Specifically, as Figure 5 shown, an inclined groove 7 is formed in the side wall at the bottom of the locking block 312. A limiting block 8 is fixedly connected to the top surface of the locking groove 314. The side wall of the limiting block 8 is inclined and contacts the inclined groove 7.

[0034] Specifically, as Figure 5 shown, a sealing gasket 10 is adhesively bonded to the top of the housing 1, and a sealing groove 11 is formed in the bottom surface of the end cover 2. The sealing gasket 10 is inserted and matched with the sealing groove 11.

[0035] During use, when installing the end cover 2 and the housing 1, by aligning the first identifier 5 with the second identifier 6, the end cover 2 is inserted into the top of the housing 1. The sealing performance between the end cover 2 and the housing 1 can be achieved through the sealing gasket 10 and the sealing groove 11. At this time, the locking block 312 is inserted into the slot 313. Then, the end cover 2 is rotated. At this time, the bottom of the locking block 312 enters the locking groove 314, and the inclined groove 7 of the locking block 312 contacts the limiting block 8. At this time, the locking block 312 realizes the installation connection between the end cover 2 and the housing 1. The end cover 2 and the housing 1 can be limited and locked through the locking assembly 32. When disassembling the end cover 2, the locking between the end cover 2 and the housing 1 is released through the locking assembly 32. Then, the end cover 2 is rotated in the reverse direction, so that the locking block 312 enters the slot 313. At this time, the end cover 2 is pulled upward from the housing 1 to disassemble the micro hollow cup motor. In this way, the connection strength between the end cover 2 and the housing 1 can be improved, and the micro hollow cup motor can be disassembled quickly.

[0036] Specifically, as Figure 5As shown, the locking assembly 32 includes a screw 321, a rotating block 322, a lifting plate 323, a locking rod 324, a connecting block 325, a hinge block 326 and a locking head 327. The screw 321 is threadedly connected to the middle part of the end cover 2, the rotating block 322 is fixedly connected to the top of the screw 321, the lifting plate 323 is movably arranged at the bottom of the screw 321, four locking rods 324 are hinged on the side wall of the lifting plate 323, four connecting blocks 325 are fixedly connected to the bottom surface of the end cover 2, the hinge block 326 is arranged in the middle part of the connecting block 325, the hinge block 326 is movably connected to the locking rod 324, the locking head 327 is fixedly connected to the bottom end of the locking rod 324, and the locking head 327 is movably connected to the slot 313.

[0037] Specifically, Figure 5 As shown, four T-shaped rods 4 are fixedly connected to the bottom surface of the end cover 2, and the lifting plate 323 is movably connected to the T-shaped rods 4.

[0038] Specifically, Figure 5 As shown, the end surface of the lock head 327 is arranged in an arc shape.

[0039] Specifically, Figure 5 As shown, an anti-skid sleeve 9 is sleeved on the side wall of the rotating block 322, and an anti-skid pattern is arranged on the side wall of the anti-skid sleeve 9.

[0040] When in use, after the locking block 312 enters the locking groove 314, the screw rod 321 is rotated by the rotating block 322 to rotate, and the anti-slip sleeve 9 can increase the friction between the human hand and the rotating block 322. The bottom end of the screw rod 321 is movably connected to the lifting plate 323 and pushes the lifting plate 323 to move downward. The T-shaped rod 4 guides and limits the movement of the lifting plate 323. Due to the arrangement of the connecting block 325 and the hinge block 326, the other end of the locking rod 324 will be curved upward during the downward movement of the lifting plate 323 Movement causes the lock head 327 to enter the slot 313. At this time, a limit lock is achieved between the end cover 2 and the casing 1, and the end cover 2 cannot rotate. At this time, the end cover 2 and the casing 1 are locked. When disassembling the micro hollow cup motor, the screw rod 321 is rotated in the opposite direction. At this time, the lifting plate 323 moves upward, and the other end of the lock rod 324 will fall in an arc shape. The lock head 327 will be separated from the slot 313. At this time, an unlocking limit is achieved between the end cover 2 and the casing 1, thereby improving the safety of disassembling the micro hollow cup motor.

[0041] By adopting the above technical solution, the problem that the clamp arm is difficult to restore its deformation after the extrusion block of the existing micro hollow cup motor which is easy to disassemble is solved, which makes it difficult to remove the end cover 2 from the casing 1, and at the same time, there is a low connection strength between the casing 1 and the end cover 2, which can easily lead to loosening between the end cover 2 and the casing 1 under the action of external force is solved.

[0042] Working principle: When the present application is in use, first install the end cover 2 and the housing 1, insert the end cover 2 into the top of the housing 1, and then the locking block 312 is inserted into the slot 313, and then the end cover 2 is rotated to move, and the bottom of the locking block 312 enters the locking slot 314, and the inclined slot 7 of the locking block 312 contacts the limit block 8, and the locking block 312 enables the end cover 2 to be installed and connected with the housing 1, and at the same time, the locking head 327 moves to one side of the slot 313, and the screw rod 321 is rotated by the rotating block 322 to rotate, and the bottom end of the screw rod 321 is movably connected with the lifting plate 323 and pushes the lifting plate 323 to move downward. Due to the setting of the connecting block 325 and the hinge block 326, during the downward movement of the lifting plate 323, the locking rod 32 The other end of 4 will have an arc-shaped upward movement, so that the lock head 327 enters the slot 313. At this time, the end cover 2 and the casing 1 are limitedly locked, and the end cover 2 cannot rotate. At this time, the end cover 2 and the casing 1 are locked. When disassembling the micro hollow cup motor, the screw rod 321 is rotated in the opposite direction. At this time, the lifting plate 323 moves upward, and the other end of the lock rod 324 will have an arc-shaped downward movement, and the lock head 327 will be out of the slot 313. Then, the end cover 2 is rotated in the opposite direction to make the lock block 312 enter the slot 313. At this time, the end cover 2 and the casing 1 are pulled upward to realize the disassembly of the micro hollow cup motor. In this way, the connection strength between the end cover 2 and the casing 1 can be improved, and the micro hollow cup motor can be quickly disassembled.
