Description

Technical Field

[0001] This utility model relates to the field of motor accessories technology, and in particular to a motor rear cover with a dustproof sealing gasket. Background Technology

[0002] As the power component of industrial equipment, the stability and lifespan of the motor are of paramount importance. The motor back cover is a key barrier that protects the internal structure of the motor and isolates it from the external environment. Although existing motor back covers have certain protective functions, they still have shortcomings in actual use. First, in terms of sealing performance, the fit between many back covers and the housing relies on simple mechanical bonding or a single sealing ring. Under the influence of vibration and thermal expansion and contraction during long-term operation of the equipment, gaps will be generated at the joint, allowing external dust and oil stains to enter the motor and contaminate the components.

[0003] Because the motor generates heat during operation, heat dissipation holes are provided on the back cover. However, these holes also become a direct channel for external dust to enter. Dust accumulates inside the heat dissipation holes, which can affect heat dissipation efficiency and cause short circuits or wear, seriously affecting the lifespan of the motor.

[0004] Furthermore, in terms of disassembly and maintenance, in order to secure the back cover and maintain its aesthetic appearance, many back covers have smooth outer walls and are installed using tight fit or magnetic attraction. This makes it difficult for operators to grip the smooth back cover when maintenance is needed, lacking an effective point of leverage, resulting in extremely difficult disassembly, which is time-consuming, labor-intensive, and poses safety risks.

[0005] Therefore, this utility model proposes a motor rear cover with a dustproof sealing gasket to overcome the shortcomings of the prior art. Utility Model Content

[0008] Preferably, the sealing mechanism further includes an elastic rubber ring, which seals the connection gap between the motor cover and the housing.

[0009] Preferably, the outer wall of the motor cover has two hidden grooves.

[0010] Preferably, the lifting handle is fully accommodated within the hidden slot when folded up.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 The quick-access mechanism 4 includes a hidden groove 401 formed on the outer wall of the motor cover 1. In this embodiment, two hidden grooves 401 are formed on the outer wall of the motor cover 1. A connecting plate 403 is fixedly connected to the inner wall of the hidden groove 401.

[0024] As another preferred embodiment, in order to keep the outer wall of the motor cover 1 flat when the lifting handle 402 is not in use, the lifting handle 402 is completely accommodated in the hidden groove 401 in the storage state.

[0025] As another preferred embodiment, in order to ensure effective interception of dust entering from the heat dissipation hole 304, the main dustproof pad 303 is located below the airflow path of the heat dissipation hole 304.

[0026] As another preferred embodiment, in order to ensure that the magnetic ring 305 can be accurately aligned and provide uniform adsorption force when the cover is closed, the magnetic ring 305 of the motor cover 1 and the magnetic ring 305 of the magnetic groove 306 are coaxially arranged.

[0027] As another preferred embodiment, in order to realize the storage and unfolding action of the lifting handle 402, the lifting handle 402 rotates around the central axis of the rotating rod 404.

[0028] As another preferred embodiment, in order to construct a stable rotational support structure, the connecting plate 403 is fixedly connected perpendicular to the rotating rod 404.

[0029] Working principle: During assembly and use, the motor cover 1 is detachably installed on the top of the housing 2. The sealing mechanism 3 provides multiple layers of protection. First, the sealing ring 301 at the bottom of the motor cover 1 is embedded in the inner wall of the embedding groove 302 at the top of the housing 2, forming a tight fit at the inner joint of the motor cover 1 and the housing 2, effectively blocking the path of dust or oil stains from entering through internal gaps. For the heat dissipation hole 304 opened at the top of the motor cover 1, the main dustproof pad 303 is fixedly connected to the inner wall of the housing 2, and the main dustproof pad 303 is located below the airflow path of the heat dissipation hole 304. When external dust attempts to enter through the heat dissipation hole 304 with the airflow, it will be effectively intercepted by the main dustproof pad 303, preventing dust from entering. If the medium enters the motor, it will affect the operation. In addition, to prevent the medium from seeping into the external connection gap between the motor cover 1 and the housing 2, the elastic rubber ring 307 seals the gap, providing a third layer of protection. To ensure that the motor cover 1 remains firmly fixed when the equipment vibrates during operation, the magnetic ring 305 fixedly connected to the bottom of the motor cover 1 cooperates with the magnetic ring 305 fixedly connected to the inner wall of the magnetic groove 306 at the top of the housing 2. The two magnetic rings 305 are coaxially set to ensure accurate alignment. When the cover is closed, the two magnetic rings 305 are magnetically connected to each other, generating sufficient adsorption force to prevent the motor cover 1 from accidentally loosening or falling off, thus ensuring the normal operation of the equipment. When the motor needs maintenance or repair, the lifting handle 402 rotates around the central axis of the rotating rod 404 and is fully housed in the hidden groove 401 on the outer wall of the motor cover 1 in the retracted state. At this time, the outer surface of the motor cover 1 remains flat, avoiding accidental bumps and damage to the lifting handle 402. The lifting handle 402 is stably installed in the hidden groove 401 through the structure of the rotating rod 404 and the fixed connection to the connecting plate 403. When it is necessary to remove the motor cover 1, the operator flips the lifting handle 402 out of the hidden groove 401 and pulls the lifting handle 402 upward. The applied external force will overcome the magnetic attraction between the magnetic ring 305 at the bottom of the motor cover 1 and the magnetic ring 305 on the inner wall of the magnetic groove 306, causing the two magnetic rings 305 to separate, and then the motor cover 1 can be easily removed. The whole disassembly process is convenient and safe.
