The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1～Fig. 4, a kind of cycle rack safety device, described support 11 is hinged on hind axle 12, described hind axle 12 is arranged on the rear end of vehicle frame, described safety device 10 comprises shell 2, described vehicle frame fixedly mounts described shell 2 near described hind axle place, in described shell 2, away from hind axle side, be rotatably mounted quadrntnt 4, described quadrntnt 4 comprises two straight flanges and bent limit, the rear end of two straight flanges and the fulcrum of described quadrntnt 13 join, the front end of two straight flanges and the two ends on bent limit join, the rear end connection metal film 1 of described quadrntnt 4, in described shell 2, have the gap swinging for described metal film 1, described shell 2 is fixedly connected with one end of retracing spring 8, the other end of retracing spring 8 is fixedly connected with described quadrntnt 4, described metal film 1 is positioned at the side of described trailing wheel 9, small sheave 3 in the middle of also installing in described shell 2, in the middle of described, small sheave 3 is positioned at described shell 2 and close hind axle side, the top installing card rope body 6 of described support 11,
On described fulcrum 13, be fixedly connected with one end of steel rope 5, described steel rope 5 is walked around a straight flange and is connected with described card rope body 6 through described shell 2 with after bent limit, middle small sheave 3.
Further, when metal film 1 is during in extended state, the extension line of a straight flange and described in the middle of small sheave 3 tangent.
Further, in described shell 2, also install and add small sheave 14, described additional small sheave 14 is positioned at the front portion of described middle small sheave 3, and described steel rope 5 passes shell after walking around middle small sheave 3, additional small sheave 14.
The interior installation rope locking machine 7 of described shell 2, described steel rope 5 is through described rope locking machine 7.
Described fulcrum 13 is dead sheave, and described dead sheave is installed in rotation in shell 2, and described dead sheave is fixedly connected with quadrntnt 4.
A straight flange of described quadrntnt and bent limit are provided with the groove for steel rope location.
In Fig. 1, fan-shaped solid 4 ends stretch out metal film 1 and fulcrum 13 consubstantialities, can rotate around the axle center of fulcrum.Seizing wire 5 is by behind the straight, curved limit of fan-shaped solid 4, by middle small sheave 3, additional small sheave 14, reach again the outside of shell, finally be connected on the card rope body 6 being fixed on support, seizing wire is exposed to the length of outside and can be adjusted by rope locking machine 6.The effect of card rope body 7 is to guarantee that body interior rope is tension.
Fig. 2 is fundamental diagram, wherein when car stops, and 11 times support ground of support, in support safety device 10, metal film 1 is just vertical with wheel axial filament under the effect of retracing spring 8.When forgetting by bike while packing up support, the tyre rotation of trailing wheel 9 will be touched steel wire and 1 collision of metal film and be sent abnormal sound, and situation as shown in Figure 3.When support 11 is packed up after support, the pulling force that card rope body 6 can make seizing wire 5 elongations make the steel rope of support safety device 10 inside overcome spring 8 with support rotation makes metal film 1 parallel with wheel direction, thereby sound will disappear.
Fig. 3 is the birds-eye view that support safety device 10 is arranged on bicycle rear end, the Vibration Condition of visible metal film 1.
In the present embodiment; shell 2 is hard straight shell protection; on shell, design fixed cover; be fixed on connecting rod, described metal film is fixed on the rear end of quadrntnt, and its length should guarantee just in time can collide with trailing wheel steel wire when trailing wheel rotates; solid physical efficiency is rotated around the axle center of fulcrum (dead sheave axis fixed thereon); drive again metal film to rotate, on shell side, have the open seam of rotating for metal film, stitch the wide thickness that is slightly larger than metal film.Retracing spring one end is connected with the part that quadrntnt upper surface protrudes, and the other end is connected on shell.Steel rope one end is fixed on the position that quadrntnt side and small sheave are close to, groove arrangement along quadrntnt part side, small sheave and additional small sheave in the middle of walking around successively again, finally the rope locking machine by shell is connected with card rope body, and card rope body 6 makes inner wire rope all the time in tensioned state.
This device is when installing and using, by the fixed cover on shell, it is fixed on public bicycles connecting rod, when support is in keeping state well, fixed cover on shell is by the stressed tension of steel wire rope, this power enough overcomes the pulling force of retracing spring, make metal film and trailing wheel steel wire direction be parastate, support safety device does not affect trailing wheel like this, and people just can not produce sound in the process of riding.If support is not packed up, metal film can automatically restPose under spring force effect, now metal film and trailing wheel steel wire are in vertical state, support safety device will send the clash from metal film and trailing wheel steel wire in bicycle is advanced process, with this, reaches the object of reminding driver.This device is easy to use and reliable, low cost of manufacture, and its hard shell is owing to being irregularly shaped, can be with metal or plastic shape-forming processing and manufacturing, other materials all can market purchasing.
The present embodiment is applicable to a kind of safety device of the bicycle of single pendulum pin, is particularly suitable for the relatively uniform public bicycle type of specification.
