Description
Technical field
The utility model is related to bicycle installation and maintenance fields, and in particular to a kind of multi-speed bicycle flywheel dismounting device.
Background technology
Bicycle is conventional industries, has the history of more than 100 years, and due to environmental protection and traffic problems, bicycle becomes generation
The indispensable walking-replacing tool in various countries of boundary.Cycling is also the popular movement of body-building.Has the data statistics of CYCLEPRESS
It has been shown that, whole world bicycle demand size are maintained at the level of 1.06 hundred million, and bicycle annual volume is about 5,000,000,000 dollars.
And the bicycle sold currently on the market, whether mountain bike or highway car are most of all with speed change gear.
And bicycle assembling is also important bicycle production process, various for the tool kind of bicycle bicycle assembling, is passed
It is more troublesome to bicycle freewheel dismounting on system, so as to reduce production efficiency to a certain extent, add bicycle repairing hardly possible
Degree.Therefore it is badly in need of designing a kind of multi-speed bicycle flywheel dismounting device.
Utility model content
Technical problem to be solved in the utility model is in view of the above shortcomings of the prior art, to provide a kind of dismounting side
Just, efficient multi-speed bicycle flywheel dismounting device.
The technical solution adopted in the utility model is：A kind of multi-speed bicycle flywheel dismounting device, including handle, feature
It is, further includes pincers and the lower pincers of flywheel pincers on flywheel pincers, described handle one end and the lower clipper joint of flywheel pincers, clamp and be arranged on flywheel pincers
The lower pincers of flywheel pincers are upper and to clamp lower pincers with flywheel arranged in a crossed manner, on flywheel pincers pincers and the lower corresponding one side of pincers of flywheel pincers be equipped with and
Flywheel chain wheel matched chain buckle, is respectively equipped with card key on the flywheel pincers on pincers and the lower pincers of flywheel pincers, the card key it
Between be connected with spring.
Further preferably, the lower pincers of the flywheel pincers are equipped with spacer pin, and the spacer pin is arranged on one clamped on flywheel pincers
Side.
Further preferably, pincers are connected by screw under pincers are clamped with flywheel on the flywheel pincers.
Further preferably, pincers and the lower pincers of flywheel pincers are arc shape on the wheel pincers.
Further preferably, pincers and flywheel clamp lower pincers using Cr12Mov materials on the flywheel pincers.
Compared with prior art, the beneficial effects of the utility model are：Convenient disassembly is not only greatly saved when in use
Muscle power, and any damage will not be caused to flywheel, preferably protect flywheel；It, can be right meanwhile by the setting of spring
Provision for disengagement is effectively protected provision for disengagement, prolongs the service life into row buffering.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 uses schematic diagram for the utility model.
It illustrates：Pincers, 4- screws, 5- chains buckle, 6- card keys, 7- on the lower pincers of 1- handles, 2- flywheels pincers, 3- flywheels pincers
Spring, 8- spacer pins, 9- flywheels, 10- chain wheels, 11- box spanners, 12- flywheel nuts.
Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is further described.
A kind of multi-speed bicycle flywheel dismounting device, including handle 1, pincers 3 and the lower pincers 2 of flywheel pincers on flywheel pincers, described
1 one end of hand is connected with the lower pincers 2 of flywheel pincers, and pincers 2 are arranged in a crossed manner under pincers 3 clamp on the lower pincers 2 of flywheel pincers and with flywheel on flywheel pincers,
Pincers 3 clamp lower pincers 2 with flywheel and are connected by screw 4 on flywheel pincers.Pincers 3 and the lower 2 corresponding one sides of pincers of flywheel pincers are equal on flywheel pincers
Equipped with on flywheel 9 10 matched chain of chain wheel buckle 5.It is reached by chain buckle 5 and the cooperation of the chain wheel on chain wheel 10
Clamping effect is provided to flywheel 9.Flywheel nut 12 is used cooperatively with flywheel disassembling wrench by box spanner 11, you can
9 easy removal of flywheel is got off.
Card key 6 is respectively equipped on pincers 3 and the lower pincers 2 of flywheel pincers on flywheel pincers, spring 7 is connected between the card key 6, is made
Used time spring 7 can provide chucking power, while spring 7 has certain cushion effect when dismantling energetically, does not allow this provision for disengagement
It is fragile, prolong the service life.
More specifically, the lower pincers 2 of the flywheel pincers of the utility model are equipped with spacer pin 8, and the spacer pin 8 is arranged on flywheel
The one side of pincers 3 on pincers.Spacer pin 8 limits the maximum open angle clamped on flywheel.
Pincers 3 and the lower pincers 2 of flywheel pincers are arc shape on flywheel pincers.
Pincers 3 and the lower pincers 2 of flywheel pincers use Cr12Mov steel on flywheel pincers, by vacuum heat, ensure that flywheel clamps up and down
Rigidity meet the requirements.
The above only expresses the preferred embodiment of the utility model, and description is more specific and detailed, but not
Can the limitation to the utility model patent scope therefore be interpreted as.It should be pointed out that the ordinary skill people for this field
For member, without departing from the concept of the premise utility, several deformations can also be made, improves and substitutes, these all belong to
In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
