Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a waterproof sealed motor. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magnetic-electrical power rotation torque. Electric motors are currently widely used in many fields such as mechanical processing, automotive electrical equipment, national defense, aerospace, and industrial and agricultural production. They are an indispensable driving device at present.

[0003] Since the use scenarios of electric motors are relatively complex and changeable, they inevitably involve some application scenarios that are easy to come into contact with water. Since existing electric motors generally do not have strong waterproof capabilities, water in the working environment is likely to enter the inner cavity of the motor, especially through the gap between the output shaft of the motor and the motor housing, entering the inner cavity of the motor, causing damage to the motor and easily causing large losses. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above problems and provide a waterproof sealed motor.

[0006] Furthermore, the extrusion assembly includes a rectangular rod that passes horizontally through the shell, and a connecting plate and a pull plate are fixed on the inner and outer sides of the rectangular rod respectively. A pair of symmetrical connecting rods are vertically fixed at both ends of the inner side of the connecting plate, and the ends of the pair of connecting rods are respectively hinged with mounting plates. The pair of mounting plates are hinged and a hook is fixed on the inner side of the junction. A pull rod passes horizontally through the rectangular rod and is slidably connected, and a hook two and a pull plate two are fixed on the inner and outer sides of the pull rod respectively. The hook two and the two hooks are each tied with a pull rope, and the arc-shaped absorbent cotton is fixed on the inner side of the mounting plate.

[0007] Furthermore, a spring is wound around the rectangular rod between the connecting plate and the inner wall of the shell.

[0008] Furthermore, rectangular holes through which the rectangular rod passes are provided at both ends of the shell, and through hole 1 and through hole 2 through which the output shaft passes are provided at the end of the shell and the center of the blocking plate, respectively.

[0009] Furthermore, the blocking plate divides the shell into a plurality of cavities, and the water outlet is arranged at the lower end of the cavity.

[0010] The advantages of the utility model compared with the prior art are:

[0011] 1. The output shaft is sealed multiple times through several blocking plates in the housing, and the moisture entering the housing is discharged through several water outlets, thereby enhancing the waterproof performance of the motor.

[0012] 2. An arc-shaped absorbent cotton in contact with the output shaft is provided at the end closest to the motor to absorb the moisture that will enter the gap between the output shaft and the motor housing.

DETAILED DESCRIPTION

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] Combined with Figure 1-2A waterproof sealed motor comprises a motor 1, a motor bracket 2 is installed at the lower end of the motor 1, an output shaft 3 is arranged at the front end of the motor 1, a shell 4 through which the output shaft 3 passes is screwed to the front end of the motor 1, a plurality of blocking plates 17 through which the output shaft 3 passes are arranged in the shell 4, a plurality of water outlet holes 401 are arranged at the lower end of the shell 4, and extrusion components 5 are respectively arranged on both sides of the shell 4 near one end of the motor 1, and arc-shaped absorbent cotton 6 in contact with the output shaft 3 is installed at the end of the extrusion component 5.

[0020] During the specific implementation of the utility model, the output shaft 3 is sealed multiple times through a plurality of blocking plates 17 in the housing 4, thereby enhancing the waterproof performance of the motor, and discharging the moisture entering the housing 4 through a plurality of water outlets 401, and an arc-shaped absorbent cotton 6 in contact with the output shaft 3 is provided at the end closest to the motor 1 to absorb the moisture that will enter the gap between the output shaft 3 and the housing of the motor 1, and after a period of time, the moisture on the arc-shaped absorbent cotton 6 is squeezed out through the squeezing component 5 to prevent the arc-shaped absorbent cotton 6 from having too much moisture and reducing its absorption capacity, and the squeezed moisture is discharged through the water outlet 401, thereby enhancing the waterproof performance of the motor.

[0021] Combined with Figure 3 The extrusion assembly 5 includes a rectangular rod 7 passing through the shell 4 horizontally, and a connecting plate 8 and a pull plate 1 9 are fixed inside and outside the rectangular rod 7 respectively. A pair of symmetrical connecting rods 10 are vertically fixed at both ends of the inner side of the connecting plate 8. The ends of the pair of connecting rods 10 are respectively hinged with mounting plates 11. The pair of mounting plates 11 are hingedly arranged and a hook 12 is fixed inside the junction. A pull rod 13 passes through the rectangular rod 7 horizontally and is slidably connected. A hook 2 1301 and a pull plate 2 14 are fixed inside and outside the pull rod 13 respectively. A pull rope 15 is tied to each of the hook 2 1301 and the two hooks 12. The arc-shaped absorbent cotton 6 is fixed to the inner side of the mounting plate 11.

[0022] When the extrusion assembly 5 is in use, pull the pull plate 1 9 to make the rectangular rod 7 pull the connecting plate 8, and then pull the mounting plate 11, so that the arc-shaped absorbent cotton 6 is away from the output shaft 3. The other hand pulls the pull plate 2 14 to make the pull rod 13 pull the hook 12 and the pair of pull ropes 15 thereon. Since the pair of mounting plates 11 are hinged and the mounting plates 11 and the pull rod 13 are hinged, the arc-shaped absorbent cotton 6 on the pair of mounting plates 11 overlap and are squeezed, thereby squeezing out the moisture in the arc-shaped absorbent cotton 6 to prevent the arc-shaped absorbent cotton 6 from having too much moisture and reducing its absorption capacity.
