Example 3

As shown in fig. 8, this embodiment is substantially the same as embodiment 2, except that the cleaning mechanism is replaced by an air bag 44, specifically, the air bag 44 is located at the bottom of the piston 32, a liquid outlet pipe 45 is disposed at the left side of the air bag 44, and a connection between the liquid outlet pipe 45 and the water storage box 33 is a hollow spherical structure, so that when the piston 32 pushes the air bag 44, the liquid outlet pipe 45 is driven to swing, a liquid inlet pipe 46 is disposed at the right side of the air bag 44, and a return spring 47 is disposed inside the air bag 44, so as to facilitate the return of the air bag 44.

The working principle is as follows: when the high-strength automobile swing arm is used, an oil supplementing mechanism, an adjusting mechanism and a cleaning mechanism are arranged to supplement oil to the joint of the automobile swing arm, improve the strength of the swing arm and provide working space for three steps; the mounting plate 2 is connected with an automobile tire, the water inlet pipe 42 is connected with an automobile water tank, when the automobile runs, the mounting plate 2 moves downwards under the action of gravity, the pressing block 4 is driven to move downwards through the bottom of the buffer 3, the pressing block 4 drives the rotating rod 5 to move downwards, and the rotating rod 5 drives the gear 6 to rotate through the ball 14; as shown in fig. 2 and 3, when the pressing block 4 moves, the pressing ring 12 is driven to move downwards, the bottom of the pressing ring 12 is far away from the opening on the inner side of the oil storage tank 10, enters the oil outlet box 11 from the opening on the outer side of the pressing ring 12, and is finally discharged from the opening on the outer side of the oil outlet box 11, so that the swing arm body 1 and the mounting plate 2 are lubricated, and the effect of automatic oil supplement is achieved; the gear 6 drives the toothed plate 15 to move along the sliding seat 43, the first push rod 16 is pushed to move leftwards, the first push rod 16 drives the adjusting rod 17 to swing by taking the sleeve wheel 18 as a fulcrum, and the other side of the adjusting rod 17 is driven to swing downwards by utilizing the V-shaped structure of the adjusting rod 17; as shown in fig. 4 and 5, the adjusting rod 17 pulls the nut 20 to move along the outer side of the screw rod 19 through the first connecting seat 21, the screw rod 19 is driven to rotate, the screw rod 19 drives the two positioning tubes 24 to rotate, the positioning tubes 24 drive the supporting rod 26 to rotate through the supporting plate 25, the supporting rod 26 drives the ejector rod 27 to swing, the mounting seat 28 is used as a fulcrum, the height of the buffer 3 is raised, and therefore the effect of improving the buffering strength of the swing arm is achieved. The push rod 27 drives the inserted rod 29 to move, the universal balls 30 on two sides of the inserted rod 29 drive the pressure rod 31 to move downwards, and the pressure rod 31 drives the piston 32 to move along the inside of the water storage box 33, so that the air pressure in the water storage box 33 is reduced, water is discharged from the water outlet pipe 36, and the effect of cleaning dirt is achieved; as shown in fig. 6 and 7, when the push rod 27 swings, the second push rod 39 drives the water outlet pipe 36 to move with the second connecting seat 38 as a pivot, the water outlet pipe 36 swings up and down with the rotary column 35 as a pivot, and meanwhile, when the press rod 31 moves, the press rod 40 is driven to rotate, and the press rod 40 drives the fan blade 41 to rotate, so that the effect of improving the spraying surface is achieved. Through the cooperation use between the above-mentioned mechanism, solved in the in-service use, because traditional automobile swing arm is when being used for oversize vehicle, long-term transportation is gone, and the road surface jolts, and the buffer strength of swing arm is lower to the junction of swing arm and auto-suspension needs manual oil supplementation to maintain, lacks the function of automatic oil supplementation, and simultaneously, large automobile chassis's dirt is more, and inconvenient clearance is located to the swing arm, improves the problem of bearing a burden of swing arm.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
