Abstract

The utility model discloses a safety device for bicycle for efficiently preventing the risks of collision, side slipping and falling of riding bicycles during traffic congestion, on narrow roads and on snow-covered roads. Both sides of the frame are respectively provided with a telescopic bearing rod. The telescopic bearing rods are charged and discharged by the circular pulling switch installed on the handle. The bracket can form a V shape support with the frame after being released so as to stabilize the body. The actions of charging and discharging can be accomplished during riding the bicycle.

Description

Safety device for bicycle

The utility model is to belong to protection a kind of additional device of safety by bike.

Bicycle is that people's walking-replacing tool is extremely general.But the present does not also have a kind of easyly, prevents that effectively vehicle body from toppling over the device with protection human body safety.Existing lifting mode bicycle safe seat and antiskid bicycle chain, though they have played the effect of safety guard-safeguard from each different side, they still have problems such as operation inconvenience, increase car resistance.

The purpose of this utility model be provide a kind of for people are daily by bike and anti-topple over, the anti-safety device that breaks away, be particularly useful for the elderly, women and use during road surface accumulated snow tyre skidding in the winter time.

The utility model is in the both sides of vehicle frame two band spring housing tubular type telescopic support struts to be installed vertically respectively, and it can be by being contained in the disk stay-supported folding and unfolding switch control retractable on the handlebar.

Specify below in conjunction with Fig. 1, Fig. 2, Fig. 3.

Strut bar is made up of outer tube (1), extrapolation spring (2), expansion link (3), small rubber wheel (4), about respectively one group, vertically be installed in vehicle frame both sides (see figure 3) by fixed mount (7) respectively.A kind of disk stay-supported folding and unfolding switch is housed on handlebar, and it is made up of withdrawal spanner (8), shell (9), capstan winch (10), switch lever (11), steel rope (12).Switch lever (11) links with the front brake pull bar.When bicycle meets accident under steam, brake handgrip before holding, so switch lever (11) breaks away from capstan winch (10) steel rope (12) is loosened, shrinking connecting-rod (6) also is released simultaneously, expansion link (3) is released by extrapolation spring (2), expansion link under the support of shrinking connecting-rod (6) (3) forms the chevron pointing support of 25 ° of angles respectively with vehicle frame, vehicle body can be stabilized on the road surface.After dangerous the eliminating, pioneer's car travels, treat that vehicle body operates steadily after, move downwards and regain spanner (8), so about two cover supports under the effect of steel rope (12) and shrinking connecting-rod (6), regain.So far all action is finished under steam.Use next time and repeat said process.

Use small rubber wheel (4) at ordinary times, meet the heavy snow sky winter and change little anti-sideslip wheel (5) more temporarily.

Outstanding feature of the present utility model is that two cover support bars are installed respectively in the vehicle frame both sides. No matter blow, rain and winter slipperiness on roads, can not worry for tumbling by bike again. No longer regain after also whole support can being opened in case of necessity, allow vehicle body travel under the support of four wheels, its sense of security can strengthen widely.
