DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1 The utility model provides a technical solution: an outer rotor motor capable of improving waterproof effect, comprising: a housing 1 and a cover 6, a magnet 2 is installed inside the housing 1, a stator core 3 is arranged on one side of the magnet 2, a winding 4 is wound around the outer side of the stator core 3, an output shaft 5 is connected in the middle of multiple groups of stator cores 3 through bearings, and the cover 6 is installed on one side of the housing 1;

[0024] A screw rod 7 is connected through one side of the cover 6, and a movable rod 8 is connected to one side of the screw rod 7 through a rotating shaft. A push rod 9 is installed on the same side of the movable rod 8 away from the screw rod 7, and a movable block 10 is provided at the end of the push rod 9 away from the movable rod 8 through an inclined groove. A movable spring 11 is connected between the movable block 10 and the groove of the cover 6, a clamping block 12 is installed on one side of the movable block 10, and a mounting block 13 is provided on one side of the clamping block 12. A pressure block 14 is installed on the same side of the movable rod 8 away from the push rod 9, a sealing strip 15 is provided between the pressure block 14 and the groove of the outer shell 1, and the screw 7 and the cover 6 are threadedly connected.

[0025] In specific implementation, the outer rotor motor capable of improving the waterproof effect can dock the cover 6 to one side of the shell 1 when sealing is required, so that the mounting block 13 on one side of the shell 1 docks into the groove of the cover 6, and then the screw 7 is rotated, the screw 7 is connected to the movable rod 8 through the bearing, and the screw 7 is connected to the movable rod 8 through the bearing. At this time, rotating the screw 7 will drive the movable rod 8 to move, so that the movable rod 8 drives the pressure block 14 to move in the direction of the sealing strip 15, and moves the pressure block 14 out of the groove of the cover 6, and squeezes the sealing strip 15 in the groove of the shell 1. Since the sealing strip 15 is made of rubber, the sealing strip 15 will be deformed when squeezed. At this time, after the sealing strip 15 is deformed, it will have a sealing effect on the gap between the shell 1 and the cover 6. At the same time, the movable rod 8 drives the push rod 9 to move, and the push rod 9 passes through the inclined surface. The movable block 10 will be squeezed, so that the movable block 10 drives the card block 12 to move in the direction of the mounting block 13, and the movable spring 11 on one side is stretched by the movable block 10, and the card block 12 is inserted into the groove of the mounting block 13. The cover 6 can be fixed to one side of the shell 1 by connecting the card block 12 to the mounting block 13, so that the sealing effect is better. On the contrary, when the cover 6 needs to be removed, the screw rod 7 can be rotated in the opposite direction, so that the screw rod 7 drives the movable rod 8 to move in the opposite direction, and the top rod 9 will not squeeze the movable block 10. Then the movable block 10 is reset by the movable spring 11, and the card block 12 is moved out of the groove of the mounting block 13, and the pressing block 14 does not squeeze the sealing strip 15 in the groove of the shell 1, so that the cover 6 can be removed from the shell 1, which is convenient for the user to replace the sealing strip 15 of the shell 1.

[0026] See also Figure 1 and Figure 3 It can be seen that when in use, the screw rod 7 can be rotated according to the use requirements, and then the movable rod 8 drives the pressure block 14 to squeeze the sealing strip 15. At this time, the gap between the cover 6 and the shell 1 can be sealed, and the card block 12 can be connected to the groove of the mounting block 13, so that the cover 6 can be connected to the shell 1 more tightly, so that the sealing is better.

[0027] An oil storage tank 16 is installed inside the shell 1, and a rotating rod 17 that passes through the shell 1 is connected to the top of the oil storage tank 16. A bevel gear set 18 is installed at the bottom of the rotating rod 17. A connecting shaft 19 is connected to the middle of the bevel gear set 18, and an eccentric wheel 20 is sleeved on the outer side of the connecting shaft 19. A movable plate 21 is provided at the bottom of the eccentric wheel 20. Telescopic rods 22 are installed on the tops of both sides of the movable plate 21. A telescopic spring 23 is connected between the telescopic rod 22 and the groove of the oil storage tank 16, and the movable plate 21 forms a telescopic structure through the telescopic rod 22 and the telescopic spring 23.

[0028] In a specific implementation, the outer rotor motor capable of improving the waterproof effect can be used by rotating the rotating rod 17. Since the bottom of the rotating rod 17 is connected to a bevel gear set 18, the bevel gear set 18 is composed of two bevel gears meshing with each other, one bevel gear is connected to the rotating rod 17, and the other bevel gear is connected to the connecting shaft 19. At this time, rotating the rotating rod 17 will drive the connecting shaft 19 to rotate through the bevel gear set 18. An eccentric wheel 20 is installed on the outside of the connecting shaft 19. The rotation of the connecting shaft 19 will drive the eccentric wheel 20 to rotate. Since the rotation center of the eccentric wheel 20 is biased upward, when the eccentric wheel 20 rotates, the eccentric wheel 20 will move upward as a whole. At this time, the eccentric wheel 20 will not squeeze the movable plate 21 at the bottom, and then the movable plate 21 will drive the entire movable plate 21 to move upward through the reset effect of the telescopic rod 22 and the telescopic spring 23. When the movable plate 21 moves upward, the through hole at the bottom of the oil storage tank 16 is exposed, and then the lubricating oil inside the oil storage tank 16 will be guided to the output shaft 5 through the through hole and the oil guide pipe. At this time, the lubrication effect of the output shaft 5 can be achieved, so that the output shaft 5 can rotate more stably. Conversely, the rotating rod 17 can be rotated in the opposite direction. The rotating rod 17 will drive the connecting shaft 19 to rotate in the opposite direction through the bevel gear set 18, and the eccentric wheel 20 will rotate downward, squeezing the movable plate 21 at the bottom. The movable plate 21 is squeezed and moves downward, blocking the holes at the bottom of the oil storage tank 16 to avoid leakage of the lubricating oil.

[0029] See also Figure 2 , Figure 4 and Figure 5 It can be seen that when in use, according to the needs of use, by rotating the rotating rod 17, with the cooperation of the bevel gear set 18 and the connecting shaft 19, the eccentric wheel 20 does not squeeze the movable plate 21, and then the movable plate 21 moves upward through the telescopic spring 23. At this time, the lubricating oil inside the oil storage tank will flow to the output shaft 5, thereby facilitating the lubrication of the output shaft 5.

[0030] To sum up: when the outer rotor motor capable of improving the waterproof effect is in use, the outer rotor motor can be connected to a power source through a wire, and then the winding 4 and the stator core 3 inside the housing 1 will rotate with the cooperation of the magnet 2, thereby driving the output shaft 5 to rotate, so that the entire outer rotor motor can work normally. This is the prior art and will not be elaborated on here. This is the use feature of the outer rotor motor capable of improving the waterproof effect. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
