Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a single-phase asynchronous motor. Background Art

[0002] Single-phase asynchronous motors are low-power, single-phase asynchronous motors powered by a single-phase AC power supply (AC220). Their power ratings are typically low, generally no greater than 2kW. Single-phase asynchronous motors make up the majority of low-power asynchronous motors. The requirements for motors vary significantly across applications, necessitating the use of a variety of motor types to meet these requirements.

[0003] A search of Chinese patent publication number CN212183283U discloses a single-phase asynchronous motor, which belongs to the field of motor manufacturing technology. The patent base is fixedly connected with vertical enclosure plate 1 and vertical enclosure plate 2. The upper end of vertical enclosure plate 1 is distributed with through hole 1, and the upper end of vertical enclosure plate 2 is distributed with through hole 2. Rectangular connection positions are distributed on the outer walls of both sides of the motor body, and the rectangular connection positions are provided with connection holes. The connecting bolts pass through the through holes 1 and 2 on vertical enclosure plate 1 and vertical enclosure plate 2 and are spirally connected to the connection holes of the rectangular connection positions on the outer walls of both sides of the motor body, so that the motor body and vertical enclosure plate 1 are detachably connected. The motor body of the device is detachably connected to a motor base, which is detachable and easy to assemble and connect. The motor base has an elastic rubber pad layer, which has the effect of shock absorption and energy absorption, solving the problems of existing single-phase asynchronous motors that are difficult to assemble, inconvenient to drill and use, and poor shock absorption effect. However, in this device and the prior art, when the motor is installed and used, if it needs to be installed in a small space, it is often difficult to align the output shaft with the drive member, and it is not convenient to adjust the direction of the motor output shaft after it is fixed. Repeated adjustments are required, which is inconvenient to use and its practicality needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figure 1 — Figure 7 As shown, a single-phase asynchronous motor includes a motor body 101, a plurality of connecting seats 102 are welded on the motor body 101, a connecting column 103 is connected to the connecting seat 102 by bolts, a connecting mechanism is installed on the connecting column 103, and a fixing mechanism is provided on the connecting mechanism. The connecting mechanism includes a rotating plate 201, and a rotating ring 204 is connected to one side of the rotating plate 201 by bolts. The fixing mechanism includes a mounting plate 301, and an annular groove 304 for rotating the rotating ring 204 is opened on the mounting plate 301. The fixing mechanism is provided with a locking mechanism for controlling the relative movement between the connecting mechanism and the fixing mechanism.

[0027] In this embodiment, a central groove 202 is opened on one side of the connecting mechanism, and a latching tooth 203 is welded in the central groove 202. A limit ring 305 is connected to the mounting plate 301 by a bolt. The locking mechanism includes a screw 404, which is rotatably connected in the limit ring 305. The center positions of the central groove 202, the rotating ring 204 and the annular groove 304 are on the same straight line. The rotating ring 204 cooperates with the annular groove 304, so that the mounting plate 301 can rotate relative to the rotating plate 201. The screw 404 is threaded with a retaining ring 405, which cooperates with the latching teeth 203. The retaining ring 405 is sleeved in the limiting ring 305. Rotating the screw 404 can push the retaining ring 405 to move horizontally, thereby switching the locking relationship between the retaining ring 405 and the latching teeth 203 to ensure the output stability of the motor body 101.

[0028] In this embodiment, one end of the screw 404 is connected to the second bevel gear 403 by a bolt, and the second bevel gear 403 is meshed with the first bevel gear 402. The top side of the first bevel gear 402 is connected to the rotating rod 401 by a bolt. The staff rotates the rotating rod 401 on the top side of the mounting plate 301, and the rotating rod 401 drives the first bevel gear 402 to rotate, and the first bevel gear 402 drives the second bevel gear 403 to rotate, and the second bevel gear 403 drives the screw 404 to rotate, so that the retaining ring 405 moves back and forth on the screw 404, thereby switching the position of the retaining ring 405. When the retaining ring 405 is located in the center groove 202 of the rotating plate 201, the retaining ring 405 has a blocking effect on the locking tooth 203 to prevent the rotating plate 201 from rotating.

[0029] In this embodiment, the rotating rod 401 is rotatably connected to the mounting plate 301, and a number of connecting parts 302 are welded on the side of the mounting plate 301. A threaded hole 303 is provided in the connecting part 302. The connecting part 302 is fixed to the mounting plane by screwing a bolt into the threaded hole 303, making the installation of the motor body 101 more convenient. After the position is fixed, the direction of the output shaft of the motor body 101 can still be changed to prevent the situation where it is difficult to install due to jamming.

[0030] Working principle: When the device is in use, the connecting piece 302 is first fixed to the installation plane by screwing the bolt into the threaded hole 303. After fixing the position of the motor body 101, the rotating rod 401 is rotated, and the rotating rod 401 drives the first bevel gear 402 to rotate, and the first bevel gear 402 drives the second bevel gear 403 to rotate, and the second bevel gear 403 drives the screw 404 to rotate, so that the snap ring 405 moves back and forth on the screw 404, thereby switching the position of the snap ring 405. When the snap ring 405 is located in the center groove 202 of the rotating plate 201, the snap ring 405 has a blocking effect on the locking tooth 203 to prevent the rotating plate 201 from rotating. When the snap ring 405 is out of the center groove 202 and is located in the mounting plate 301, the rotating plate 201 and the mounting plate 301 can rotate, thereby adjusting the direction of the motor body 101, facilitating the installation of the transmission assembly, and easy to use.

[0031] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
