Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts, in particular to an end shaft with a sealing component. Background Art

[0002] The air conditioner indoor unit can blow air outwards because the fan blade roller inside it rotates under the drive of the motor. The end of the existing fan blade roller is fixedly installed with a component for connecting the motor output shaft, namely an end shaft. The end of the end shaft corresponding to the motor output shaft is provided with a "D"-shaped slot that matches the shape of the motor output shaft. During installation, it is only necessary to insert the end shaft into the motor output shaft.

[0003] Although the existing end shaft can realize the fixed connection between the fan blade roller and the motor output shaft, it lacks a sealing component and has no sealing effect. Since the motor usually needs lubrication to reduce friction and wear during operation, it is easy for the lubricating oil to flow into the end shaft due to leakage during the rotation of the motor output shaft, thereby contaminating the fan blade roller and accelerating the damage of the fan blade roller, indirectly affecting the normal operation of the air conditioning equipment. In order to maintain the good operation of the air conditioning equipment, we propose an end shaft with a sealing component. Utility Model Content

[0033] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , in the figure, the end shaft body 1 and the screw 14 are both made of stainless steel material; specifically, the end shaft body 1 and the screw 14 made of stainless steel material have good rust prevention and corrosion resistance.

[0034] Working principle: The end shaft body 1 is installed on the wind blade roller. When installing the wind blade roller, first make the D-shaped slot 2 on the end shaft body 1 correspond to the output shaft of the motor, and then with a little force, the end shaft body 1 can be inserted and sleeved on the output shaft of the motor. Since the D-shaped rubber ring 6 on the D-shaped groove 5 is in close fit with the output shaft of the motor, a good sealing effect can be achieved. Then turn the screw 14 upward, and the screw 14 will rotate upward in the screw hole 21 on the end shaft body 1 until the end of the screw 14 is in close fit with the output shaft of the motor, then the installation of the wind blade roller can be realized.

[0035] When the D-shaped rubber ring 6 on the circular plate 3 is needed after a long period of use, first, remove the fan blade roller from the air conditioner indoor unit, then use the thumb and middle finger of one hand to pinch the two sides of the annular plate 4 near the lower edge (that is, the thumb and middle finger are respectively located on both sides of the outer arc surface of the arc-shaped rubber pad 12 near the upper edge), then place the index finger of the hand between the two push plates 9 and move downward, then in the process of the index finger continuously moving downward, the two push plates 9 will move away from each other, and the two push plates 9 will drive the respective arc plates 8 on them to move away from each other (in this process, the guide grooves 18 on the two arc plates 8 will be on the corresponding annular plates 4 The two arc plates 8 will drive the L-shaped plates 10 on each other to move away from each other, the two L-shaped plates 10 will drive the plug posts 15 on each other to slide away from each other in the inner walls of the corresponding annular plates 4 and cylindrical tubes 7, and the two plug posts 15 will drive the circular rings 16 on each other to slide away from each other in the corresponding cylindrical tubes 7 (in this process, the springs 17 between the two cylindrical tubes 7 and the circular rings 16 on each other will be squeezed on the outer walls of the corresponding plug posts 15), and the two plug posts 15 will slide outward in the sockets 22 on the corresponding end shaft bodies 1 and completely leave the sockets 22.

[0036] Then, keep the finger posture unchanged while pulling the annular plate 4 outwards, and the annular plate 4 will slide forward on the end shaft body 1 (in this process, the two rectangular blocks 19 on the annular plate 4 will slide forward in the corresponding rectangular grooves 20 on the end shaft body 1) until the annular plate 4 completely leaves the end shaft body 1. The D-shaped rubber ring 6 can be removed from the end shaft body 1. Similarly, the replaced D-shaped rubber ring 6 can be installed back on the end shaft body 1 according to the opposite operation, which makes disassembly and assembly easy.

[0037] It should be noted that this end shaft prevents the lubricating oil from leaking into the end shaft body 1 during the rotation of the motor output shaft, thereby avoiding contamination of the fan blade roller, which is beneficial to maintaining the good operating condition of the air-conditioning equipment. At the same time, the D-shaped rubber ring 6 used to provide a sealing effect is easy to disassemble and assemble from the end shaft body 1.
