Description

Technical Field

[0001] The utility model relates to the technical field of motor end covers, in particular to a motor cover with a sealing structure which is easy to disassemble. Background Art

[0002] Motor accessories refer to the parts assembled into the motor by the motor manufacturer, which are the original motor accessories. The parts that are replaced due to damage caused by improper use or wear are called motor accessories. Generally, the life of accessories is not as long as that of original parts. Motor accessories can be divided into five parts, of which the motor end cover is one part. In order to improve the sealing performance, the traditional practice is to apply sealing glue radially at the joint of the end cover and the shell to achieve a thorough seal. However, this sealing method is costly and complex in process, and has high requirements for the application of sealing glue. If the sealing glue is uneven, it will not only cause low working efficiency of the motor during operation, but also easily cause wear of the sealant, resulting in poor waterproof performance of the motor, seriously affecting the performance and service life of the motor.

[0003] According to Chinese patent CN113346663A, a motor end cover with a quickly replaceable sealing mechanism includes a motor body, a protective chamber is fixedly installed on the top and bottom of the motor body, a pad is movably installed on the right side of the motor body, a ferrule with two ends penetrating and extending to the outside of the pad is movably installed on the right side of the pad, a spring is fixedly installed between the pad and the ferrule, the ferrule is in a side U shape, two installations are opened inside the pad, the spring increases the buffering between the ferrule and the pad, a sealing chamber is arranged between the left side of the pad and the right side of the motor body, the inner wall of the sealing chamber is covered with a sealing gasket, the sealing chamber is in a side U shape, and plays a close fit, a locking component is arranged on the top and bottom of the motor body, a bottom plate is arranged on the back of the motor body, and a protective assembly is arranged between the front of the bottom plate and the back of the motor body. The sealing chamber, the ferrule, and the pad together constitute the motor end cover, and the spring tightly protects the sealing chamber.

[0004] When the motor end cover in the above device is sealed at the connection with the motor casing, the sealing effect of the motor end cover achieved only by the sealing chamber, the ferrule and the gasket is poor, especially since no sealing structure is provided at the connection between the motor end cover and the motor casing, so that external water can still penetrate into the interior of the motor end cover. Only the sealing gasket inside the sealing chamber can activate the effect of one layer of protection, thereby causing the overall protection effect of the device to deteriorate. Therefore, a motor cover with a sealing structure that is easy to disassemble is proposed to solve the above problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a motor cover with a sealing structure that is easy to disassemble. The utility model has the advantages of adopting a double protection structure to achieve a good sealing effect when the motor end cover is connected to the motor casing. The utility model solves the problem that the existing motor end cover, when sealed with the motor casing, only relies on an internal sealing chamber to achieve motor waterproofing, resulting in poor waterproofing effect and external water penetrating in from the connection.

[0006] To achieve the above object, the utility model provides the following technical solution: a motor cover with a sealing structure that is easy to disassemble, comprising a motor housing, the outer surface of which is detachably connected to a motor end cover, the outer surface of which is fixedly connected to a fixing ring plate, and a sealing assembly is arranged between the fixing ring plate and the motor end cover;

[0007] The sealing assembly includes a waterproof rubber ring, which is fixedly connected to the inside of a fixed ring plate. An annular clamping plate is fixedly connected to the right side of the fixed ring plate. An inner sealing ring is fixedly connected to the bottom of the motor end cover. A protective plate is movably connected to the right side of the motor housing. A connecting rod is rotatably connected to the left side of the motor end cover. The left sides of the two connecting rods are fixedly connected to connecting springs, and the left sides of the two connecting springs are fixedly connected to the same cover plate.

[0008] Furthermore, two connecting plates are fixedly connected to the left side of the fixing ring plate, first bolts are passed through the two connecting plates, and the fixing ring plate is fixedly connected to the motor housing through the two first bolts.

[0009] Furthermore, two mounting plates are fixedly connected to the right side of the fixing ring plate, second bolts are passed through the inside of the two mounting plates, and the motor end cover is detachably connected via the two second bolts.

[0010] Furthermore, a first sealing groove is provided inside the fixing ring plate, and the waterproof rubber ring is located inside the fixing ring plate through the first sealing groove.

[0011] Furthermore, an inner sealing ring is fixedly connected to the outer surface of the annular clamping plate, a second sealing groove is provided inside the inner sealing ring, and the annular clamping plate and the inner sealing ring are located inside the inner sealing ring through the second sealing groove.

[0012] Furthermore, an annular sealing gasket is fixedly connected to the bottom of the inner sealing ring, and the annular sealing gasket is in contact with the inner surface of the fixed ring plate.

[0013] Furthermore, a sealed cavity is opened inside the cover plate, and the protective plate is located inside the cover plate through the sealed cavity.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The motor cover with a sealing structure is easy to disassemble. When the motor end cover is installed on the outer surface of the motor housing, the fixing ring plate is first sleeved on the outer surface of the motor housing and then fixedly connected by two first bolts, and the motor end cover is inserted into the inside of the first sealing groove and then fixed by the second bolt, thereby achieving the effect of easy disassembly; after installation, the waterproof rubber ring is sealed by squeezing the inside of the first sealing groove, and the annular clamping plate and the inner sealing ring are clamped into the inside of the inner sealing ring for sealing, thereby achieving the effect of internal and external double protection; and the existence of the protective plate and the cover plate ensures that if the inside of the motor housing encounters an accidental situation where external water penetrates, the cooperation of the protective plate and the cover plate can achieve the effect of internal re-sealing, further improving the sealing of the motor end cover to the motor housing, thereby greatly improving the service life of the motor.
