Abstract
The invention relates to a rotary supporting rod type bicycle capable of preventing forward turnover. The bicycle comprises a bicycle frame, a front fork frame, a front wheel, a rear wheel, a saddle, a handlebar and a brake component, wherein the front fork frame comprises a front fork upright tube and front fork supporting tubes; the front fork upright tube is assembled on the bicycle frame; the front fork supporting tubes are connected with the front fork upright tube and are positioned on two sides of the front wheel. The bicycle is characterized by also comprising a supporting plate, a rotary supporting rod, a supporting roller and a lock plate, wherein the supporting plate is fixed onto the lower parts of the front fork supporting tubes; the rotary supporting rod is mounted on the supporting plate through a rotary shaft; a lock hole is formed in one side, positioned on the rotary shaft, of the supporting plate; a lock pin is inserted into the lock hole; the axis of the rotary shaft is parallel to that of the front wheel; the free end of the rotary supporting rod extends out of the periphery of the front wheel by 10 to 20cm; the supporting roller is mounted at the free end of the rotary supporting rod; the lock plate is arranged at the fixed end of the rotary supporting rod; an unfolding hole and a folding hole which can be opposite to the lock hole and can allow the penetration of the lock pin are formed in the lock plate. According to the bicycle, a forward turnover accident caused by sudden brake of the front wheel of the bicycle can be effectively avoided, and the safety performance of the bicycle is improved.
Description
Technical field
The invention belongs to technical field of bicycles, particularly relate to before a kind of rotary supporting rod formula is prevented and turn over bicycle.
Background technology
Bicycle is traditional traffic means of transport, and along with the continuous progress of mankind's vehicle, various electronic, comfortable traffic means of transport occurs in succession.But bicycle is because of its environmental protection, natural feature and be more and more subject to pursuing the people of quality of the life and favor.Mountain bike and highway car are two kinds of vehicles that people's outdoor activities the most often use, and along with the development of bike tech, the performance of mountain bike and bicycle is become better and better, and compares standard bicycle vehicle, lighter faster.
The riding position of mountain bike and highway car is the forward upper body prone position of center of gravity, and compare ordinary bicycle, mountain bike and highway car need artistic cycling more.High-grade mountain bike very light weight, people, under the state of riding at a high speed, if front-wheel emergency brake, then turn over accident before as easy as rolling off a log appearance, especially when new hand or emergency situation brake, more easily use front-wheel emergency brake.And compared with the car body side that the accident of rebuilding or renovate before car body and tradition easily occur turns over and cause the accident, consequence is much serious, easily causes comparatively major injury to bicyclist, seriously more can be fatal.The structure that current mountain bike and highway car turn over before all not preventing bicycle, safety factor is low.
Summary of the invention
The present invention turns over bicycle before providing a kind of safer rotary supporting rod formula anti-for solving in known technology the technical matters that exists.
The technical scheme that the present invention takes for the technical matters existed in solution known technology is: turn over bicycle before a kind of rotary supporting rod formula is anti-, comprise vehicle frame, front forked frame, front-wheel, trailing wheel, saddle, handlebar and brake assemblies, described front forked frame comprises the vertical tube of front fork that is fitted on described vehicle frame and is connected the front fork arm being positioned at front-wheel both sides with vertical tube of front fork, it is characterized in that: also comprise support plate, rotary supporting rod, support rollers, jam plate, described support plate is fixed on the bottom of described front fork arm, described rotary supporting rod is arranged on described support plate by rotating shaft, the side described support plate being positioned at described rotating shaft has lockhole, lock pin is fitted with in described lockhole, the axis of described rotating shaft and the axis being parallel of described front-wheel, the free end of described rotary supporting rod stretches out described front-wheel periphery 10cm-20cm, the free end of described rotary supporting rod installs described support rollers, the fixed end of described rotary supporting rod is provided with described jam plate, described jam plate has can and the deployment aperture that can make described lock pin through and recovery holes relative with described lockhole.
The present invention can also adopt following technical measures:
Described support rollers has roller bearing, and the two ends of described roller bearing are arranged on the rotary supporting rod of front-wheel both sides respectively by bearing.
All have negative thread in described lockhole, deployment aperture and recovery holes, described lock pin is the bolt mated with described negative thread, and described bolt has turning handle.
The advantage that the present invention has and good effect are:
Bicycle described in the present invention have prevent bicycle before the rotary supporting rod that turns over, thus bicycle effectively can be avoided to turn over accident before causing because of front-wheel emergency brake, improve the safety performance of bicycle.
