Description

Technical Field

[0001] The utility model relates to the field of motors, and more specifically, to a dust-proof motor. Background Art

[0002] A motor is an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. Divided by the type of working power supply, it can be divided into DC motors and AC motors. In modern industry, agriculture, transportation, commerce, household appliances, medical appliances, cultural and educational offices, etc., motors play an important role. Common motors include components such as a housing, a stator, a rotor, and a rotating shaft. Existing motors will add a dust-proof cover at the tail for dust prevention. However, after using for a period of time, a lot of dust will adhere to the dust-proof cover, so the dust-proof cover needs to be cleaned regularly. And the existing dust-proof cover is usually fixed to the housing by bolts.

[0003] During the cleaning process, maintenance personnel need to disassemble the dust-proof cover. Otherwise, during the cleaning process, dust is likely to enter the motor due to the extrusion during wiping. And when cleaning, the disassembled bolts and other fasteners need to be collected, and it is easy to lose them during the disassembly, assembly, and storage processes, resulting in the dust-proof cover unable to be refixed to the motor housing.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a dust-proof motor.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A dust-proof motor, including a housing and a dust-proof cover, the dust-proof cover is rotatably connected to the housing, two symmetrically arranged limiting blocks are fixedly connected to the housing, a convex block is fixedly connected to the movable end of the dust-proof cover, a groove for the convex block to be embedded is formed between the two limiting blocks, a self-locking chain is provided on one of the limiting blocks, and a round hole for the self-locking chain to pass through is opened on the other limiting block. The self-locking chain includes a connecting strip and an inserting rod. A slot for the inserting rod to be inserted is opened on the connecting strip. When the inserting rod is inserted into the slot, the self-locking chain forms a closed loop.

[0007] The utility model is further provided as: One end of the inserting rod is fixedly connected with an elastic positioning block, and the diameter of the positioning block is greater than the width of the slot.

[0008] The utility model is further provided as: The positioning block is made of rubber material.

[0009] The utility model is further provided as: A guiding groove communicating with the slot is opened on the connecting strip, and the guiding groove can accommodate the positioning block to pass through.

[0010] The present utility model is further configured such that the width of the guiding groove becomes smaller closer to the insertion slot.

[0011] The present utility model is further configured such that when the insertion rod is inserted into the insertion slot, the positioning block abuts against the surface of the connecting strip, and the insertion rod is arranged perpendicular to the connecting strip.

[0012] The present utility model is further configured such that both the housing and the dust-proof cover are made of stainless steel material.

[0013] In summary, the present utility model has the following beneficial effects: By setting the cooperation of the convex block and the groove, and the locking of the self-locking chain, the protective cover can be disassembled and installed conveniently and quickly, so that maintenance personnel do not need to worry about the loss of fasteners such as bolts during the cleaning process. When the insertion rod is inserted into the insertion slot, the self-locking chain forms a closed loop, realizing the self-locking function of the dust-proof cover. Since the self-locking chain is an integral structure, compared with traditional fasteners such as bolts, it is less likely to be lost during the disassembly process, ensuring that the dust-proof cover can be stably fixed on the motor housing, facilitating subsequent installation operations.

[0017] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0018] Embodiment:

[0019] A dust-proof motor, as Figure 1 and Figure 2 shown, includes a housing 1 and a dust-proof cover 2. A stator, a rotor and a rotating shaft are arranged inside the housing 1. By providing the dust-proof cover 2, it is possible to prevent external dust, foreign objects, etc. from entering the inside of the housing 1, thereby ensuring that the inside of the housing 1 is clean and tidy, enabling the motor to operate continuously and efficiently. Further, both the housing 1 and the dust-proof cover 2 are made of stainless steel material. The stainless steel material has high strength and hardness, and can resist external impacts and mechanical damages. The housing 1 and the dust-proof cover 2 made of this material have better protection performance. At the same time, the stainless steel surface is smooth and not easy to adhere to stains and dust, which is more convenient in terms of cleaning and maintenance, and can maintain long-term cleanliness and beauty.

[0020] Specifically, Figure 1 and Figure 2 As shown, the dust cover 2 is rotatably connected to the shell 1, and two symmetrically arranged limit blocks 3 are integrally formed on the shell 1. A protrusion 4 is fixedly connected to the movable end of the dust cover 2, and a groove 5 for accommodating the protrusion 4 to be embedded is formed between the two limit blocks 3. A self-locking chain 6 is provided on one of the limit blocks 3, and a round hole for the self-locking chain 6 to pass through is opened on the other limit block 3. Further, the self-locking chain 6 includes a connecting bar 7 and an insertion rod 8. The connecting bar 7 is provided with a slot 9 for accommodating the insertion of the insertion rod 8. When the insertion rod 8 is inserted into the slot 9, the self-locking chain 6 forms a closed loop. By setting the cooperation between the protrusion 4 and the groove 5, and locking the self-locking chain 6, the protective cover can be removed and installed conveniently and quickly, so that maintenance personnel do not need to worry about the loss of fasteners such as bolts during the cleaning process. When the rod 8 is inserted into the slot 9, the self-locking chain 6 forms a closed loop, realizing the self-locking function of the dust cover 2. Since the self-locking chain 6 is an integral structure, it is less likely to be lost during the disassembly process than traditional fasteners such as bolts, ensuring that the dust cover 2 can be stably fixed on the motor housing 1, facilitating subsequent installation operations.

[0021] like Figure 1 and Figure 2 As shown, one end of the plug rod 8 is fixedly connected with an elastic positioning block 10, and the diameter of the positioning block 10 is larger than the width of the slot 9. Specifically, the positioning block 10 is made of rubber material. By setting the positioning block 10, when the plug rod 8 is located in the slot 9, the positioning block 10 can play an anti-separation role and prevent the plug rod 8 from slipping out of the slot 9. Furthermore, when the plug rod 8 is inserted into the slot 9, the positioning block 10 presses against the surface of the connecting strip 7 and the plug rod 8 is arranged perpendicular to the connecting strip 7. Since the protrusion 4 and the groove 5 are both located directly below the rotation axis of the dust cover 2, the dust cover 2 will sag under the action of gravity, and the self-locking chain 6 can prevent the protrusion 4 from separating from the groove 5. The above arrangement ensures the stability of the dust cover 2 during use of the motor. At the same time, the rubber material also has a certain elasticity, which can form a buffer layer between the plug rod 8 and the slot 9, reducing the risk of the plug rod 8 separating from the slot 9 due to motor vibration, thereby improving the stability of the motor.

[0022] Further, such as Figure 1 and Figure 2As shown, a guiding groove 11 communicating with the slot 9 is formed in the connecting bar 7. The guiding groove 11 can accommodate the positioning block 10 to pass through. The width of the guiding groove 11 is smaller closer to the slot 9. The design of the guiding groove 11 allows the positioning block 10 to move along a specific path during insertion, thus ensuring that the plug rod 8 can be accurately inserted into the slot 9 without error. As the width of the guiding groove 11 gradually decreases, the guiding force received by the positioning block 10 gradually increases, which helps to achieve more precise positioning. When repairing and cleaning the dust cover 2, the design of the guiding groove 11 makes the disassembly process simpler and more convenient. The positioning block 10 can slide out of the guiding groove 11, saving time and improving work efficiency.

[0023] The above description is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications should also be regarded as the protection scope of the present invention.
