Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0025] The present utility model will be further described below with reference to the embodiments.
[0026] Embodiment: Refer to Figures 1 to 6, A front end cover of a vertical motor facilitating oil injection, comprising a front end cover body 1 and an installation sleeve 13. The installation sleeve 13 is installed inside the front end cover body 1. A through hole is provided on the side wall of the front end cover body 1, and an arc-shaped groove 4 is provided inside the front end cover body 1. A reset mechanism is arranged inside the arc-shaped groove 4. A socket 14 is rotatably installed inside the installation sleeve 13. A connecting cylinder 10 is fixedly communicated with the side wall of the socket 14. The top end of the connecting cylinder 10 extends out of the through hole. A knob 11 is fixedly connected to the outside of the connecting cylinder 10. The knob 11 is rotatably connected to the top of the front end cover body 1. Rotating the knob 11 drives the connecting cylinder 10 to rotate, and then drives the socket 14 to rotate, so as to adjust the position of the connecting plate 9, and further adjust the position of the connecting pipe 12 to inject oil into the rear end of the motor. A connecting plate 9 is fixedly connected to the outer wall of the socket 14. The reset mechanism is in transmission connection with the connecting plate 9. The connecting plate 9 is rotatably installed inside the front end cover body 1. A connecting pipe 12 is communicated and arranged at the top of the front end cover body 1. A sealing plug is arranged at the top of the connecting pipe 12 to seal the connecting pipe 12, so as to prevent dust from falling into the inside of the connecting pipe 12 when not in use and affecting the next oil injection. The connecting pipe 12 is a telescopic pipe. When the connecting plate 9 rotates, it will not affect the use of the connecting pipe 12. The bottom end of the connecting pipe 12 is communicated with the top of the connecting plate 9. When oil injection is required, the knob 11 can be rotated. Under the cooperation of the connecting cylinder 10 and the socket 14, the connecting plate 9 is driven to rotate, and then the position of the bottom end of the connecting pipe 12 is adjusted. Then, oil is injected into the rear end through the connecting pipe 12. After the oil injection is completed, under the action of the reset mechanism, the connecting cylinder 10, the knob 11 and the connecting plate 9 are reset. After cleaning the connecting pipe 12, the sealing plug is used to seal the connecting pipe 12 again to prevent dust from falling into the inside of the connecting pipe 12 when not in use and affecting the next oil injection.
[0027] Specifically, referring to FIG. Arc-shaped groove 4 to FIG. Spring 5, the reset mechanism includes an arc-shaped rod 6. The arc-shaped rod 6 is fixedly installed inside the arc-shaped groove 4. A spring 5 is sleeved on the outer wall of the arc-shaped rod 6. One end of the spring 5 is fixedly connected to the inner wall of the arc-shaped groove 4, and the other end of the spring 5 is fixedly connected to a pressing block 7. The pressing block 7 is slidably connected to the arc-shaped rod 6. The bottom end of the pressing block 7 is fixedly connected to the top of the connecting plate 9. When the connecting plate 9 rotates, it drives the connecting rod 8 to slide on the arc-shaped rod 6, and thus has a certain acting force on the spring 5, causing the spring 5 to deform. When there is no external force on the connecting plate 9, then under the reaction force of the spring 5, the connecting rod 8 and the pressing block 7 are driven to reset, and then the connecting plate 9 is driven to reset.
[0028] Furthermore, referring to FIG. Front end cover body 1 and FIG. Mounting plate 2, a plurality of mounting plates 2 are fixedly connected to the outer wall of the front end cover body 1. The plurality of mounting plates 2 are circumferentially arranged in an array with the axis center of the front end cover body 1 as the center. Mounting holes 3 are provided inside the mounting plates 2. Through the combined action of the mounting plates 2, the mounting holes 3 and bolts, the front end cover body 1 is installed on the rear end housing.
[0029] The working principle of the present utility model is as follows:
[0030] When refueling is required, the knob 11 can be rotated. Under the cooperation of the connecting cylinder 10 and the socket 14, the connecting plate 9 is driven to rotate, thereby adjusting the position of the bottom end of the connecting pipe 12. Since the connecting pipe 12 is a telescopic pipe, when the connecting plate 9 rotates, the use of the connecting pipe 12 will not be affected. While rotating the connecting plate 9, the connecting rod 8 is driven to move, so that the pressing block 7 slides on the arc-shaped rod 6, and then a certain extrusion force is applied to the spring 5, causing the spring 5 to deform. Then, oil is injected into the interior of the rear end through the connecting pipe 12. After the refueling is completed, under the reaction force of the spring 5, the connecting cylinder 10, the knob 11 and the connecting plate 9 are reset, so that when refueling next time, the connecting plate 9 can be adjusted to the appropriate position again. After cleaning the connecting pipe 12, the connecting pipe 12 is sealed with a sealing plug to prevent dust from falling into the interior of the connecting pipe 12 when not in use, which affects the next refueling. The position of the connecting pipe 12 can be adjusted by rotating the angle of the knob 11 to drive the connecting plate 9 to rotate, so as to refuel different positions of the rear end.
[0031] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the various embodiments of the present utility model.
