Description

Technical Field

[0001] The utility model relates to the technical field of motor casings, in particular to a motor casing and a motor. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. According to different working principles and application fields, motors can be divided into many types. The following are some common motor types: direct current motor (DC motor), alternating current motor (AC motor), stepper motor and brushless motor (BLDC motor). These are just some common motor types. Different types of motors have different characteristics and application fields.

[0003] The motor housing is a device used to protect the motor body, such as the Chinese utility model patent with patent publication number CN218648673U, which includes a base, the top of the base is fixedly connected to the casing, a plurality of ventilation holes are opened on the surface of the top of the casing, movable holes are opened on both sides of the casing surface, an exhaust component is provided on one side of the casing, reinforcement components are provided on the top and bottom of the exhaust component, and a connecting component is provided in the inner cavity of the casing.

[0004] This patent can be achieved by setting an exhaust component and a reinforcement component. After the heat dissipation motor installed inside the casing discharges its internal heat, the fan body is turned on to discharge the hot air trapped inside the casing through several ventilation holes, which increases the air circulation in the casing to a certain extent and further enhances the heat dissipation effect of the heat dissipation motor. During installation, after aligning the position of fixed block 1 on the mounting ring with fixed block 2, the connecting sleeve is rotated to initially connect with the casing so that one end of the hollow block is placed in the inner cavity of the limit sleeve. However, when disassembling the exhaust component from the casing, it is necessary to first remove the cover and then manually press the wedge block into the inside of the hollow block to unlock it. In order to ensure the stability of the connection, two reinforcement components are provided. The above action needs to be repeated twice during disassembly, and the overall operation is relatively cumbersome. In view of this, we propose a motor casing and a motor. Utility Model Content

[0007] Preferably, the locking assembly includes a limit ring, which is rotatably connected to the rear surface of the driving ring. The limit ring is also slidably mounted on the outer surface of the fixed ring. The rear surface of the limit ring is fixedly connected to a limit rod, and the rear end of the limit rod slides through the rear surface of the second fixed ring. The rear end of the limit rod is fixedly connected to the limit disk.

[0008] Preferably, a spring is fixedly connected between the limiting plate and the rear surface of the second fixing ring, and an arc-shaped groove adapted to the connecting rod is provided on the inner wall of the driving ring.

[0009] Preferably, the driving ring is slidably connected to the connecting rod, and the outer surface of the driving ring is fixedly connected to a control handle.

[0010] Preferably, the front surface of the second fixing ring is fixedly connected with a first locking tooth, and the rear surface of the driving ring is fixedly connected with a second locking tooth.

[0013] Preferably, the outer surface of the motor is provided with heat dissipation fins, the outer surface of the motor is provided with ventilation slots extending into the interior thereof, and the inner wall of the ventilation slot is fixedly connected with a dustproof net.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) After the heat dissipation casing and the heat dissipation tube are connected, the motor casing and the motor are moved by pushing the displacement ring. When the displacement ring moves, it will synchronously drive the locking rod to move. After the locking rod moves, it enters the interior of the through groove. At this time, the locking of the driving ring is released by moving the driving ring. Then, the driving ring is used to cooperate with the connecting rod to drive the rotating ring to rotate. When the rotating ring rotates, it will synchronously drive the card block to move. After the card block moves, it cooperates with the card slot to complete the locking of the locking rod. At this time, the driving ring is reset to complete the locking. Through the above structure, it is more convenient to reinforce the connection between the heat dissipation tube and the heat dissipation casing, and the connection efficiency is improved. At the same time, there is no need to flip the motor or operate in the narrow area at the bottom to unlock, which improves the practicality of the overall device.

[0016] (2) The motor housing and the motor, the driving ring uses the arc groove to cooperate with the connecting rod to drive the rotating ring to rotate when rotating, and the locking rod is locked by the card block when the rotating ring rotates. At this time, the driving ring is controlled to reset and the first locking tooth and the second locking tooth are re-engaged and locked. When unlocking, the driving ring is also used to indirectly drive the card block and the card slot to disengage. When the exhaust component is used to ventilate the interior of the heat dissipation housing, the heat dissipation fins and ventilation slots can be used to improve the heat dissipation effect of the motor, and the dustproof net can be used to prevent dust from entering the interior of the motor. Through the above structure, not only can it be more convenient to reinforce and disassemble, but the heat dissipation fins and ventilation slots can also be used to improve the heat dissipation effect of the motor, and the existence of the dustproof net can also prevent dust from entering the motor.
