Technical Field

[0001] The utility model relates to the technical field of motor shafts, in particular to a water-cooled explosion-proof vibration motor shaft with a protective structure. Background Art

[0002] A vibration motor is a device that converts electrical energy into mechanical vibration energy. It primarily generates vibration through the principles of electromagnetic induction and the interaction of magnetic fields, utilizing the rotational motion of the motor. A water-cooled explosion-proof vibration motor combines water-cooling technology with an explosion-proof design. This motor generates heat during operation, and the water-cooling system effectively dissipates this heat through circulating water, ensuring the motor operates at a suitable temperature, thereby improving its efficiency and stability. Furthermore, its explosion-proof design allows for safe use in hazardous locations where flammable and explosive gases are present. This explosion-proof design typically includes a flameproof enclosure, which tightly isolates electrical components that could generate sparks, arcs, and high temperatures to prevent them from igniting the surrounding explosive atmosphere. The shaft, commonly referred to as the "rotor," is a key component of a water-cooled explosion-proof vibration motor. During operation, a set of coils within the shaft induces a current in the stator's rotating magnetic field. This current then transforms the coils into electromagnets, generating rotational force.

[0003] In the prior art, when a water-cooled explosion-proof vibration motor is used, the shaft of the water-cooled explosion-proof vibration motor is generally exposed to the outside. When the water-cooled explosion-proof vibration motor is not needed to be used, the exposed shaft will easily cause dust, dirt, etc. to accumulate on the shaft. At the same time, collisions in the external environment are also likely to cause corrosion and wear of the shaft, which will affect the cleanliness and safety of the shaft, thereby being detrimental to ensuring the service life of the water-cooled explosion-proof vibration motor. Therefore, in order to solve the above problems, a water-cooled explosion-proof vibration motor shaft with a protective structure is proposed. Utility Model Content

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A water-cooled explosion-proof vibration motor shaft with a protective structure includes a housing and a body 1. A shaft 11 is mounted on the surface of the body 1. The body 1 is made of explosion-proof material and can strictly isolate electrical parts that may generate sparks, arcs, and high temperatures to prevent them from igniting surrounding explosive gases. The shaft 11 can transmit power to working parts.

[0024] A protective mechanism is provided on the surface of the body 1, which includes a protective sleeve 2, which is sleeved on the surface of the shaft body 11, a connecting ring 21 is fixedly connected to the surface of the protective sleeve 2, and a fixing ring 22 is fixedly connected to the surface of the body 1. The inner side of the fixing ring 22 is movably connected to a mounting groove 23, and the inner side of the fixing ring 22 is movably connected to an insertion rod 24. A slot 25 is provided on the surface of the connecting ring 21, and a first spring 26 is fixedly connected to the surface of the insertion rod 24. By setting the protective sleeve 2, the shaft body 11 can be wrapped, and then the shaft body 11 can be isolated from the outside world, which can prevent dust from accumulating on the shaft body 11, or corrosion and wear caused by contact with the outside world.

[0025] Furthermore, the connecting ring 21 and the insertion rod 24 are movably connected, the shaft body 11 moves on the inner side of the fixed ring 22, and the insertion rod 24 is movably connected to the fixed ring 22 in two groups. The insertion rod 24 is movable to be inserted into and separated from the slot 25, which facilitates the fixing and removal of the protective sleeve 2, making the protection and use of the shaft body 11 more convenient.

[0026] Furthermore, the slots 25 are opened in two groups on the surface of the connecting ring 21, one end of the first spring 26 is fixedly connected to the fixing ring 22, and the other end of the first spring 26 is fixedly connected to the insertion rod 24. Through the setting of the first spring 26, the insertion rod 24 can be reset and inserted into the slots 25, thereby fixing the connecting ring 21, so that the protective sleeve 2 is not easy to fall off when it is sleeved on the surface of the shaft body 11.

[0027] Furthermore, a lubrication mechanism is provided on the inner side of the protective sleeve 2, and the lubrication mechanism includes an oil groove 3, which is opened on the inner side of the protective sleeve 2, and a refueling pipe 31 is fixedly connected to the inner side of the protective sleeve 2, and a sealing sleeve 32 is provided on the surface of the refueling pipe 31, and an oil outlet 33 is provided at the bottom end of the oil groove 3, and a movable rod 34 is movably connected to the inner side of the oil groove 3, and a sealing plug 35 is fixedly connected to the bottom end of the movable rod 34, and a second spring 36 is fixedly connected to the surface of the movable rod 34, and a sealing gasket 37 is fixedly connected to the upper surface of the protective sleeve 2, and the movable rod 34 and the sealing gasket 37 are movably connected. Through the setting of the oil groove 3, the lubricating oil can be stored, so that after the shaft body 11 is protected, it is convenient to lubricate the shaft body 11, thereby ensuring the performance of the shaft body 11.

[0028] Furthermore, the oil outlet 33 is opened on the inner side of the oil tank 3 and the protective cover 2, and the movable rod 34 is movable on the inner side of the protective cover 2. By opening the oil outlet 33 and coordinating the movement of the movable rod 34, the sealing plug 35 can move accordingly under the action of the movable rod 34, thereby facilitating the sealing and unblocking of the oil outlet 33 through the sealing plug 35, thereby facilitating the lubrication of the machine body 1.

[0029] Furthermore, one end of the second spring 36 is fixedly connected to the movable rod 34, and the other end of the second spring 36 is fixedly connected to the sealing gasket 37.

[0030] Working principle: When in use, by pulling the insertion rod 24, the insertion rod 24 can be moved inside the fixing ring 22. At this time, the first spring 26 is in a stretched state. Then the protective sleeve 2 is put on the surface of the shaft body 11, and the connecting ring 21 is inserted into the inner side of the mounting groove 23. Then the insertion rod 24 is released. The insertion rod 24 will be reset under the rebound action of the first spring 26, and then the insertion rod 24 and the slot 25 can be inserted and engaged, so that the protective sleeve 2 can be fixed, which is convenient for protecting the shaft body 11 through the protective sleeve 2. When the shaft body 11 needs to be used, the insertion rod 24 is pulled to separate the insertion rod 24 and the slot 25, so that the fixation of the protective sleeve 2 can be released, so that the shaft body 11 can be used.

[0031] By opening the sealing sleeve 32, lubricating oil can be injected into the oil tank 3 through the filling pipe 31. When the shaft body 11 needs to be lubricated, the movable rod 34 is pulled up to make the movable rod 34 drive the sealing plug 35 to move upward, thereby separating the sealing plug 35 and the oil outlet 33. At this time, the second spring 36 is in a stretched state, so that the lubricating oil can flow out through the oil outlet 33. Then, the movable rod 34 is released, and the movable rod 34 will be reset under the rebound action of the second spring 36, so that the movable rod 34 can drive the sealing plug 35 to move downward and block the oil outlet 33, thereby achieving lubrication of the shaft body 11.
