[0012] Preferably, four limiting rods are fixedly installed inside the four chutes, and the four limiting rods are respectively slidably connected inside the four sliding rods.

[0013] Preferably, return springs are movably sleeved on the four limiting rods. One ends of the four return springs close to the four sliding rods are fixedly connected to the four sliding rods, and the other ends of the four return springs far from the four sliding rods are respectively fixedly connected to the inside of the four chutes.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] (1). For this motor bearing protection structure, when the swing handle is pushed backward, the four protective barrier plates will move relative to each other, and then the four protective barrier plates will enclose a ring, so that the protective barrier plates can block the bearing, which is convenient for blocking the bearing, and thus prevent the bearing from falling off, improve the limiting effect on the bearing, and to the greatest extent avoid the separation of the bearing from the inside of the motor cover, improving the safety of motor use.

Detailed implementation manners

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] To further understand the content of the present invention, the present invention will be described in detail with reference to the accompanying drawings.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: a motor bearing protection structure, including a motor housing 1, a motor cover plate 15 is arranged on one side of the motor housing 1, four fixing holes 16 are opened on the motor cover plate 15, a bearing 2 is arranged inside the motor cover plate 15, a main shaft 14 is rotatably connected inside the bearing 2, a protective annular housing 3 is fixedly installed on one side of the motor cover plate 15, a rotating ring 7 is rotatably connected inside the protective annular housing 3, four driving chutes 8 are opened on the surface of the rotating ring 7, the shapes of the four driving chutes 8 are inclined, four chutes 11 are opened inside the protective annular housing 3, sliding rods 9 are slidably connected inside the four chutes 11 respectively, the four sliding rods 9 are slidably connected inside the four driving chutes 8 respectively, protective baffles 4 are fixedly installed on the four sliding rods 9 respectively, a circular ring is formed by enclosing the four protective baffles 4, the diameter of the inner circle of the four protective baffles 4 is smaller than the diameter of the bearing 2, a connecting chute 6 is opened on one side of the protective annular housing 3, a swing handle 5 is slidably connected inside the connecting chute 6, the swing handle 5 is fixedly connected with the rotating ring 7, rotating wheels 10 are fixedly sleeved on the four sliding rods 9 respectively, and the four rotating wheels 10 are slidably connected inside the four driving chutes 8 respectively.

[0026] Push the swing handle 5 to make the rotating ring 7 rotate inside the protective annular shell 3. When the rotating ring 7 rotates, the driving chute 8 follows the rotation of the rotating ring 7, thereby pushing the rotating wheel 10 and the sliding rod 9 to move, and then making the sliding rod 9 slide inside the slideway 11, thereby driving the protective baffle 4 to move. At the same time, the four protective baffles 4 move away from each other and no longer block the bearing 2. When the swing handle 5 is pushed in the reverse direction, the four protective baffles 4 will move relatively, and then the four protective baffles 4 will enclose a ring, thereby making the protective baffle 4 block the bearing 2, which is convenient for blocking the bearing 2, preventing the bearing 2 from falling off, improving the limiting effect on the bearing 2, and avoiding the separation of the bearing 2 from the inside of the motor cover 15 to the greatest extent, improving the safety of motor use.

[0027] Through the setting of the four rotating wheels 10, it is convenient for the sliding rod 9 to slide inside the driving chute 8, thereby facilitating the improvement of the smoothness of the sliding rod 9 sliding inside the driving chute 8 and improving the sliding effect of the sliding rod 9.

[0028] Four limiting rods 12 are fixedly installed inside the four slideways 11. The four limiting rods 12 are respectively slidably connected to the inside of the four sliding rods 9. Four return springs 13 are movably sleeved on the four limiting rods 12. One end of the four return springs 13 close to the four sliding rods 9 is fixedly connected to the four sliding rods 9, and the other ends of the four return springs 13 far from the four sliding rods 9 are respectively fixedly connected to the inside of the four slideways 11.

[0029] When the sliding rod 9 slides inside the slideway 11, the sliding rod 9 will move on the surface of the limiting rod 12, thereby squeezing the return spring 13. Through the setting of the four limiting rods 12, it is convenient to limit the four sliding rods 9 and prevent the four sliding rods 9 from swinging inside the slideway 11, thereby facilitating the limitation that the sliding rod 9 can only slide inside the slideway 11, improving the safety and stability of the device.

[0030] Working principle:

[0031] Push the swing handle 5 to make the rotating ring 7 rotate inside the protective annular shell 3. When the rotating ring 7 rotates, the driving chute 8 follows the rotation of the rotating ring 7, thereby pushing the rotating wheel 10 and the sliding rod 9 to move, and then making the sliding rod 9 slide inside the slideway 11, thereby driving the protective baffle 4 to move. At the same time, the four protective baffles 4 move away from each other and no longer block the bearing 2. When the swing handle 5 is pushed in the reverse direction, the four protective baffles 4 will move relatively, and then the four protective baffles 4 will enclose a ring, thereby making the protective baffle 4 block the bearing 2, which is convenient for blocking the bearing 2.

[0032] When the sliding rod 9 slides inside the slideway 11, it will cause the sliding rod 9 to move on the surface of the limiting rod 12, thereby squeezing the return spring 13. Furthermore, through the arrangement of the four limiting rods 12, it is convenient to limit the four sliding rods 9 and prevent the four sliding rods 9 from swinging inside the slideway 11.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
