Detailed Description

The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

A motorcycle crash-proof rod as shown in figures 1-2 is used for being installed on a motorcycle body and structurally comprises a crash-proof rod cylinder body 1, a support rod 2 and a piston rod 3. One end of the support rod 2 is hinged to the middle part of the outer side of the anti-falling rod cylinder 1, and the upper end of the anti-falling rod cylinder 1 is provided with a horizontal mounting hole 13 for connecting with a motorcycle body; the other end of the support rod 2 is provided with a vertical mounting hole 21 which is also used for being connected with the motorcycle body and has a supporting function for the anti-falling rod cylinder body 1. One end of the piston rod 3 extends into the anti-falling rod cylinder body 1 and can reciprocate along the axis direction of the anti-falling rod cylinder body 1, and a buffer mechanism is arranged between the piston rod 3 and the anti-falling rod cylinder body 1 and can absorb energy, so that the frame of the motorcycle is prevented from being deformed due to impact. The other end of the piston rod 3 is positioned outside the anti-falling rod barrel 1, and the end part of the piston rod 3 is provided with an anti-collision rubber sleeve 14, so that the piston rod 3 is prevented from being in rigid contact with the bottom surface.

The utility model discloses a buffer gear is including setting up attenuator 4 on piston rod 3. The damper 4 divides the inner cavity of the anti-falling rod cylinder body 1 into an upper oil cavity 11 and a lower oil cavity 12, an oil retainer 10 is sleeved on the damper 4, and the oil retainer 10 is in close contact with the inner wall of the anti-falling rod cylinder body 1. Hydraulic oil is injected into the two oil cavities. A spring 5 is arranged in the upper oil cavity, one end of the spring 5 is in contact with the bottom of the anti-falling rod cylinder body 1, and the other end of the spring 5 is in contact with the damper 4. The piston rod 3 is provided with an oil passing hole 31 for communicating the upper oil chamber 11 and the lower oil chamber 12. The piston rod 3 is further sleeved with a sealing body 6 for sealing the lower end of the anti-falling rod barrel 1. The lower oil chamber 12 is located between the seal body 6 and the damper 4, and has a variable volume. The spring 5 is extended in a natural state and the hydraulic oil is located in the upper oil chamber 11, and the volume of the lower oil chamber 12 is minimized. When falling and colliding, the piston rod 3 drives the damper 4 to compress the spring 5, the pressure of hydraulic oil in the upper oil cavity 11 is increased, when the pressure of the hydraulic oil reaches a certain value, the spring gasket on the damper 4 deforms, so that the hydraulic oil can enter the lower oil cavity 12 through the oil passing hole 31, the volume of the lower oil cavity 12 is increased, and the energy absorption purpose is achieved. When the motorcycle body is centered, the volume of the upper oil chamber 11 is increased due to the action of the spring 5, and the hydraulic oil flows into the upper oil chamber 11 from the oil through hole 31, so that the crash bar is restored to the original state.

In this embodiment, the lower end of the anti-falling rod cylinder body 1 is provided with an end cover 7, and a dust ring 8 is further arranged between the end cover 7 and the sealing body 6. Make things convenient for the dismouting simultaneously, guarantee to prevent falling pole barrel 1 and seal well, realize the purpose of using for a long time.

The utility model discloses a seal 6 is provided with sealing washer 62 including sealing ring seat 61 in the outer circumference of sealing ring seat 61, and sealing ring seat 61 inboard is provided with oil blanket 63, wherein sealing washer 62 with prevent falling 1 inner walls of pole barrel and closely laminate, oil blanket 63 closely laminates with piston rod 3, this structural seal is effectual, long service life.

Furthermore, a rubber pad 64 is further arranged on the sealing ring seat 61, the upper end of the rubber pad 64 extends out of the sealing ring seat 61, and the rubber pad 64 has a buffering effect and prevents the gasket below the damper 4 from being in rigid contact with the sealing ring seat 61 and being worn.

Further crashproof gum cover 14 passes through the screw to be connected with piston rod 3, and crashproof gum cover 14 has can overlap and establish the cavity at the lower extreme of preventing falling pole barrel 1, is provided with buffer rubber 9 in the bottom of cavity, and buffer rubber 9 cover is established on piston rod 3. When the spring 5 in the upper oil cavity 11 is compressed to the utmost, the cushion rubber 9 also has a certain cushioning effect, and the anti-collision rubber sleeve 14 is prevented from directly impacting the end cover 7.
