[0003] Motors are widely used in practical applications. In many working environments, motors will be exposed to splashing water droplets, and the output shaft end of the motor is most prone to water seepage. Water seeps into the motor from the output shaft, causing failures in the stator and rotor, resulting in rotation failures, thus affecting the service life of the motor. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a waterproof motor, comprising a motor body, an output shaft is installed on the motor body, the output shaft and the motor body are connected by a bearing, and a waterproof structure for waterproofing is installed on the output shaft, and a control structure for facilitating the adjustment of the length of the power cord of the motor body is installed on the motor body.
[0006] The waterproof structure includes a sealing plug mounted on the output shaft. The sealing plug is designed to be conical. A fixing ring fixed to the bearing is provided on the outer side of the sealing plug. A thread is provided in the fixing ring. A locking ring slidably connected to the output shaft is connected to the thread in the fixing ring. A reinforcement ring used in conjunction with the sealing plug is provided in the fixing ring.

[0011] Furthermore, a knob for adjusting the rotation of the shaft is fixed to the other end of the shaft.
[0012] By means of the above technical solution, the utility model provides a waterproof motor, which has at least the following beneficial effects:
[0013] 1. Due to the setting of the waterproof structure, the utility model continuously tightens the locking ring to continuously squeeze the reinforcement ring, so that the reinforcement ring squeezes the sealing plug, strengthens the sealing effect of the sealing plug, thereby strengthening the waterproof effect of the sealing plug, preventing the possibility of water seepage at the output shaft, and thus increasing the service life of the motor body.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Figure 1-Figure 5 This is an embodiment of the utility model: a waterproof motor, including a motor body 1, an output shaft 2 is installed on the motor body 1, the output shaft 2 is connected to the motor body 1 through a bearing, and a waterproof structure 3 for waterproofing is installed on the output shaft 2, and a control structure 4 for facilitating adjustment of the length of a power cord 403 of the motor body 1 is installed on the motor body 1. The waterproof structure 3 can tighten the locking ring 303 to tightly fit the reinforcement ring 304 to the sealing plug 301, thereby enhancing the waterproof effect of the sealing plug 301 and preventing the possibility of water seepage at the output shaft 2; the control structure 4 can flexibly adjust the length of the power cord 403 on the motor body 1 to avoid the possibility of the power cord 403 being insufficient in length or being too long and easily entangled, thereby increasing the practicality of the device.
[0025] Reference Figure 1-Figure 3As shown, the waterproof structure 3 includes a sealing plug 301 which is sleeved on the output shaft 2. The sealing plug 301 is of conical design. A fixing ring 302 fixed on the bearing is provided on the outer side of the sealing plug 301. A thread is provided in the fixing ring 302, and a locking ring 303 slidably connected to the output shaft 2 is connected to the fixing ring 302 through the thread. A reinforcing ring 304 used in conjunction with the sealing plug 301 is provided in the fixing ring 302. A conical notch is provided on the side of the reinforcing ring 304 close to the sealing plug 301, and the reinforcing ring 304 is installed between the sealing plug 301 and the locking ring 303. A drain port 305 is provided at the lower end of the fixing ring 302, and a sealing column is installed in the drain port 305. When in use, the locking ring 303 is threadedly installed on the inner side of the fixing ring 302, and the locking ring 303 is tightened. During the tightening process, the locking ring 303 will move toward the sealing plug 301, thereby continuously squeezing the reinforcement ring 304, so that the reinforcement ring 304 will squeeze the sealing plug 301, thereby enhancing the sealing effect of the sealing plug 301, thereby enhancing the waterproof effect of the sealing plug 301, thereby preventing the possibility of water seepage at the motor output shaft 2, thereby increasing the service life of the motor body 1; when water seeps into the sealing plug 301, the sealing column can be opened. Since the sealing plug 301 is a conical design, water will flow into the fixing ring 304, and the water can be discharged through the drain port 305 on the fixing ring 304, which can be used to detect whether there is water seepage in the fixing ring 302, thereby knowing the sealing effect.
[0026] In this embodiment, refer to Figure 4-Figure 5 As shown, the control structure 4 includes a mounting base fixed on the motor body 1, a shell 401 is fixed on the mounting base, a rotating shaft 402 is rotatably connected inside the shell 401, a power cord 403 is wound around the rotating shaft 402, a slot for the power cord 403 to pass through is opened on the shell 401, and a limiting structure 404 for limiting the rotating shaft 402 is installed; the limiting structure 404 includes a ratchet 4041 mounted on the rotating shaft 402, a pawl 4042 rotatably connected to the shell 401 is provided on the outer side of the ratchet 4041, a spring 4043 is fixed on the pawl 4042, the other end of the spring 4043 is fixed with a fixing rod, the fixing rod is fixedly connected to the shell 401, and the other end of the rotating shaft 402 is fixed with a knob 4044 for adjusting the rotation of the rotating shaft 402. When the motor body 1 is in use and the distance between the power cord 403 and the socket strip is not enough, press the pawl 4042 and turn the knob 4044 to release the power cord 403 on the shaft 402. After it is released to a suitable length, release the pawl 4042 and drive the pawl 4042 to reset under the action of the spring 4043, and continue to limit the ratchet 4041 to prevent the shaft 402 from rotating. When the power cord 403 is too long, the power cord 403 can be reeled in by turning the knob 4044 in the opposite direction to avoid the possibility of the power cord 403 being entangled due to being too long. This structure can flexibly adjust the length of the power cord 403 to be suitable for socket strips at different distances, thereby improving the practicality and applicability of the device.
