A kind of explosion can prevent the bicycle quick rolled
Technical field
The present invention relates to technical field of bicycles, specially a kind of explosion can prevent the bicycle quick rolled.
Background technique
Bicycle is a kind of common walking-replacing tool, with the raising of rapid development and the awareness of saving energy of shared bicycle,
The use of bicycle has been brought to a new peak again, however bicycle haves the defects that some relatively common, and blowing out is it
Middle one kind, cycle tyre are divided into solid tyre and air tyre, and the risk blown out is not present in solid tyre naturally, but damping effect is poor,
It is difficult to control so that it can not substitute air tyre, but air tyre is easy for the presence of the risk blown out.
Air tyre can not just continue to ride after blowing out, and people will make wheel rim and tire during pushing bicycle
Contact, wheel rim and ground squeeze tire jointly, are easy tire secondary damage increasing the expense of maintenance, while may also can incite somebody to action
Wheel rim abrasion, and the process carried out is also laborious, discovery has Chinese patent during creating this product
CN201320425286.9, the bicycle rear rack structure with idler wheel that the patent provides a kind of, by idler wheel when blowing out
It goes to tire bottom and replaces wheel tyre walking, be the top for needing to place it tire under normal circumstances, this mode cannot use
In the front tyre of wheel, and rear tire using when have to occupy the position of back seat, greatly reduce bicycle uses function
Can, CN201320426974.7 for another example, the patent provides a kind of cycle wheels, it attached a wheel on wheel rim,
When tyre burst, accessory whorl contacts ground, but the product exactly deviates center there are a great defect, not easily-controllable
System is easy to fall down during controlling car walking, and there are security risk, current bicycle hollow tire is when blowing out
Inconvenient walking, and it is be easy to cause the damage again of wheel rim and tire, there are great defects for general solution, cannot facilitate
It uses, so needing a kind of explosion that can prevent the bicycle quick rolled.
Summary of the invention
(1) the technical issues of solving
In view of the deficiencies of the prior art, it the present invention provides the bicycle quick that a kind of explosion can be prevented rolling, solves at present
Bicycle hollow tire when blowing out inconvenient walking, and be easy to cause the damage again of wheel rim and tire, general solution
Method is there are great defect, the problem that cannot be easy to use.
(2) technical solution
In order to achieve the above object, the present invention is achieved by the following technical programs: a kind of explosion can be prevented rolling voluntarily

The outer surface of bicycle rim is run through and extended in one end, and the interior welds of the bicycle rim have support ring, the support
One side of the ring far from bicycle rim is connected with the padded circle of support, and the surface of the bicycle rim offers adjustment hole, institute
The center that adjustment hole is located at bicycle rim inner wall is stated, the inner wall of the adjustment hole slidably connects adjusting rod, the tune
One end of pole is located at the outer surface of bicycle rim, and the other end of the adjusting rod is extended to certainly by adjustment hole and open ports
The inside of driving cover tire, one end that the adjusting rod is located inside cycle casing is bonded with curved support pad, the arc branch
The thickness of stake pad is thinner than the thickness of supporting pad, and one end that the adjusting rod is located at bicycle rim outer surface offers screw thread
The inner thread in hole, the threaded hole is connected with fixed link.
Preferably, the side of the support ring is arc-shaped shape, and one side of the support ring far from bicycle rim is in recessed
Sunken arc shape.
Preferably, the cross-sectional view of the padded circle of support is in rounded shape, and the side view of the padded circle of support is in circular ring shape
Shape, the padded circle of the support and the material of support ring include rubber, the circle wall diameter of the padded circle of support and support ring
The sum of ring wall thickness will be higher by the inner wall 2cm of bicycle rim.
Preferably, the support ring is located at the inner wall center of bicycle rim, and the support ring is far from bicycle quick
The one side of rim extends to the inside of cycle casing by open ports, and the padded circle of support is located at the inside of cycle casing,
The bicycle tube is located between cycle casing and the padded circle of support.
Preferably, the adjusting rod, curved support pad quantity be three, the material of three curved support pads is equal
For rubber, the gap of 3-5cm is provided between three curved support pads, three adjusting rods are circle with the axle center of flower-drum
The fan-shaped distribution of the heart, the radian of the fan-shaped cambered surface formed between three adjusting rods are π/6, the table of three adjusting rods
Face is provided with threaded hole, and three threaded holes are threadedly coupled with the surface of the same fixed link.

Managing between corresponding secondary row travelling wheels is also mutually support, keeps balance.
(3) beneficial effect
(1) in the use of the present invention, when tyre burst, after the gas emptying inside bicycle tube, bicycle tube
All can be flat with cycle casing, the part for then supporting padded circle to be higher by bicycle rim will resist bicycle tube, voluntarily
Interior tire resists cycle casing, cycle casing and ground face contact, and bicycle rim made of metal is avoided to squeeze bicycle
Cover tire and bicycle tube and ground face contact, avoid causing secondary damage to tire, also avoid bicycle rim leeway face and rub
It wears wound.
(2) present invention does not interfere with vehicle by that will support padded circle that the center of bicycle rim inner wall is arranged in
Two sides deviate the center of gravity of son to the left and right, avoid and mutually stagger the case where leading to vehicle body not easy to control generation with another wheel.
(3) present invention is by setting jockey pulley mechanism, when tyre burst, first props up to come car, then passes through tune
Bolt control support rod is saved in containing tube internal slide, the secondary row travelling wheels of support rod one end are stretched out into containing tube, respectively by four
A secondary row travelling wheels are all stretched and, with ground face contact, on the one hand can play support with padded circle is supported simultaneously and decompose weight
Power reduces the effect of the pressure of cycle casing and bicycle tube, on the other hand can incline to avoid bicycle rim in vehicle body
When tiltedly and ground face contact.
(4) present invention passes through adjustment hole, spiral shell when not needing maintenance by setting adjusting rod and curved support pad
Pit and fixed link fix three adjusting rods simultaneously, so that three adjusting rods are fixed on a fixed position, three tune
Three curved support pads are supported to certain position by pole, and three curved support pads support support padded together with support ring
Circle avoids that padded circle recess is supported to fall, when needing repairing, fixed link is screwed out, by three adjusting rods simultaneously corresponding
Adjustment hole inside to one Slideslip of the outer surface of bicycle rim, adjusting rod drives the sliding of curved support pad, until three arcs
Shape supporting pad is recessed, then is spilt the open ports of cycle casing from bicycle rim by the tool of maintenance,
Then it is pressed down against the inside for supporting padded circle that can will support padded circle by open ports extraction cycle casing, it can also be with
It avoids supporting padded circle that bicycle tube is stopped to be released, then start padded to cycle casing, bicycle tube and support
Circle is overhauled, and has achieved the effect that not influence normal maintenance.
(5) present invention will not influence and change the original effect of air tyre, will not influence the cushioning effect of air tyre, simultaneously
The disassembly installation and maintenance that will not influence the inner tube of a tyre, so that the current bicycle hollow tire of effective solution is when blowing out
Inconvenient walking, and it is be easy to cause the damage again of wheel rim and tire, there are great defects for general solution, cannot facilitate
The problem of use.
