Abstract
The utility model provides a kind of vibrationproof handrail of lawn machine, comprise superposed cross bar is connected cross bar and lawn machine main body montant with cross bar both sides, described montant comprises outer bar and is socketed in the interior bar of inside, outer bar lower end, interior masthead portion is provided with spring, cushion pad is provided with above spring, have metallic spacer layer between cushion pad and spring, install the magnet that a pair homopolarity is relative above cushion pad, the magnet being positioned at top is fixedly connected with outside on bar inwall.The vibrationproof handrail of a kind of lawn machine that the utility model provides, vibrates the injury caused human body when can alleviate lawn machine operation.
Description
Technical field
The utility model relates to a kind of lawn machine, specifically a kind of vibrationproof handrail of lawn machine.
Background technology
In the work of gardens, lawn machine is widely used in the pruning on lawn, generally, lawn below 2000 square meters, can select hand-push type lawn machine, lawns more than 2000 or 2000 square meters, self-propelled lawn machine can be selected, no matter be hand-push type lawn machine or self-propelled lawn machine, all need workman to hold handrail all the time, control the direct of travel of lawn machine.But lawn machine is the instrument that a kind of vibration is larger, Long-Time Service, can cause Hand-arm vibration disease, occur hand fiber crops, hand is swollen, hand pain, palmar hyperhidrosis, arm are unable and the symptom such as arthralgia, severe patient can occur that finger tip is gangrenous, the obvious atrophy of hand muscle, affects hand function.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of vibrationproof handrail of lawn machine, vibrates the injury caused human body when alleviating lawn machine operation.
The technical scheme that the utility model adopts is: a kind of vibrationproof handrail of lawn machine, comprise superposed cross bar is connected cross bar and lawn machine main body montant with cross bar both sides, described montant comprises outer bar and is socketed in the interior bar of inside, outer bar lower end, interior masthead portion is provided with spring, cushion pad is provided with above spring, have metallic spacer layer between cushion pad and spring, install the magnet that a pair homopolarity is relative above cushion pad, the magnet being positioned at top is fixedly connected with outside on bar inwall.
In two montants of handrail, spring is set; the vibration of lawn machine can be absorbed; but also have certain concussion when rebounding after spring absorbing, the magnet that cushion pad is relative with homopolarity is set above spring, the reciprocating motion that spring is beated can be suppressed; the vibration of human body is passed in further minimizing; ensure the comfortableness of workman's arm, metallic spacer layer is set in the middle of cushion pad and spring, protection cushion pad; prevent cushion pad long-term constantly impact in by spring breaking down, increase the service life.
As further improvement of the utility model, on described interior bar, cover has slip cap, and slip cap is circumferentially provided with projection, and the radial groove of projection and outer bar inwall matches.During use, the projection of slip cap can only move up and down in radial groove, can not rotate therefore between bar and outer bar.Preferred described projection has four, is evenly distributed in slip cap circumferentially.
As further improvement of the utility model, on described cross bar, cover has Anti-slip cover, and between Anti-slip cover and cross bar, also cover has airsetting gum cover.Anti-slip cover ensure that safety during comfortableness and the operation of staff, and aeroge is a kind of solid matter form, one of solid that density is minimum in the world, disconnected from each other between the molecule of this gel, once be subject to high speed impact, molecule will intermesh and lock together, become expansion hard, after External Force Acting disappears, gel recovers soft original state automatically, airsetting gum cover is housed between Anti-slip cover and cross bar, when on vibration passing to cross bar, aeroge is hit power and expanding, dilated airsetting gum cover inside forms cavity and can produce damping force, absorption portion is vibrated.
As further improvement of the utility model, described montant bottom cover has dust cover, and the junction of outer bar and interior bar is enclosed within dust cover by dust cover.Prevent soil block, weeds splash and block interior bar, make it cannot proper motion.
Further improve as of the present utility model, described cushion pad is quality of rubber materials.
The advantage that the utility model has and good effect are: the vibrationproof handrail of a kind of lawn machine of the present utility model, spring, cushion pad, magnet are set on montant respectively, cross bar arrange airsetting gum cover, there is good stability, vibration isolating effect is good, the advantages such as long service life.
