Specific embodiment
Before the present invention is described in detail, it shall be noted that in the following description content, similar element is with identical
Number indicate.
Refering to fig. 1 with Fig. 2, a first embodiment of the tensioning apparatus of chain 1 of the present invention, suitable for being assembled in a car body 10
On, and be suitable for being set to by the chain 1, which includes several inner chain sheets 11, several outer chain sheets 12 and several is located at
Chain rolling 13 between the inner chain sheet 11, the tensioning apparatus of the chain 1 include a fixation of stretch section 3, one of adapter section 2, one
4, guiding elements 5 of part and an assembling section 6.
The adapter section 2 is metal material, and substantially L-shaped, and the suspention for being suitable for assembling with the car body 10 including one
Arm 21 and one from 21 bottom end of suspention arm towards the chain 1 below the extension arm 22 that extends.The suspention arm 21 is big
The plates to extend up and down are caused, and a permeable bolt 101 and a nut 102 are fixed on the car body 10.
The stretch section 3 is laminated structure made of metal, and elastic constant is k=0.01~1000N/mm, Young's modulus
For 69~220Mpa, elastic force appropriate and deformability are made it have.The substantially preceding rearwardly extending flake of the stretch section 3,
The stretch section 3 width of Y and the length of X along the longitudinal direction in left-right direction, greater than the thickness of the stretch section 3 Z along the vertical direction
Degree.The stretch section 3 includes that an assembled portion 31 combined with the extension arm 22 of the adapter section 2 and one are connected to the group
Convergence part 32 between dress portion 31 and the assembling section 6.The assembled portion 31 has the assembly hole 311 that bottom surface is extended to by top surface,
It is not necessary to limit the contour structures of the assembled portion 31 when implementation, as long as can assemble with the extension arm 22 fixed.
The fixing piece 4 passes through the assembly hole 311 to be combined the assembled portion 31 with the extension arm 22 locking.
The guiding element 5 is located at one end far from the adapter section 2 of the stretch section 3, and is located at the outside of 1 slack list of chain.
The guiding element 5 of the present embodiment is installed in rotation in the assembling section 6 through a spindle 50, and including a central wheel portion 51,
The side wheel portion 52 of two two opposite sides for being connected to the center wheel portion 51 and one between the side wheel portion 52 and from
The radially projecting protruding portion 53 of 51 periphery of center wheel portion.Wherein, each side wheel portion 52 has several lightening holes 521, setting
The lightening hole 521 can mitigate the weight of the guiding element 5, reach lightweight demand.When implementing, the loss of weight in each side wheel portion 52
521 quantity of hole can be at least one, and a side wheel portion 52 can only be arranged.The protruding portion 53 is suitable for pushing the chain
1 chain rolling 13.
The assembling section 6 connects the stretch section 3 and the guiding element 5, and is alternatively arranged including two along left and right directions Y and leads in this
The side wall 61 of two opposite sides of part 5.When implementation, which can also only include the side wall 61.
It should be noted that the metalwork that the adapter section 2 and the stretch section 3 can be integrally formed, not with two elements
Assembling is configured to limit.The stretch section 3 and the assembling section 6 or integrally formed metalwork.Further, the combination
The metalwork that section 2, the stretch section 3 and 6 three of the assembling section can be integrally formed.
The present invention in use, due to the stretch section 3 for tool elastic force metal sheet be made, the elastic force with proper range
Constant (i.e. 0.01~1000N/mm), further arrange in pairs or groups 69~220Mpa of Young's modulus appropriate, can generate appropriate
Deformation and elastic force, and the guiding element 5 is located at 1 lower section of chain, the i.e. outside of 1 slack list of chain, therefore the elastic force of the stretch section 3 can support
It pushes away the guiding element 5 from lower to upper, that is, pushes the chain 1 from the outside of 1 slack list of chain toward the direction of inside, maintain the chain 1
Certain tensioning degree maintains have stable degree of engagement between chain 1 and sprocket wheel, and when riding is safer, can reduce chain problem.And
Overall structure of the present invention is simple, manufacturing cost is low, design is easy to be light and handy, meets the light weight demand of bicycle.The present invention is by this
Bolt 101 and nut 102 or other lock members can be mounted on bicycle, easy for installation.
Refering to Fig. 3,4, a second embodiment of the tensioning apparatus of chain 1 of the present invention is big with the structure of the first embodiment
Cause identical, be different in: the assembled portion 31 of this second embodiment, which has, several prolongs the spaced assembly hole of front-rear direction X
311.The fixing piece 4 may be selected that the assembled portion 31 and the extension arm 22 lock across either one or two of described assembly hole 311
In conjunction with.By the assembly hole 311 is arranged, when the present invention being made to be installed on the car body 10, the chain can be compressed to adjust the guiding element 5
The appropriate location of item 1, or the tightness of setting chain 1.When implementing, which can also only have an assembly hole
311, and the assembly hole 311 can change along the front-rear direction X long to the long hole of extension or the assembly hole 311 for one
It is set on the extension arm 22, so can equally lock by the fixing piece 4 and be adjusted in the appropriate location of the assembly hole 311
The guiding element 5 compresses the position of the chain 1, therefore when present invention implementation, 311 quantity of assembly hole is at least one.
The guiding element 5 of the present embodiment has several equiangularly spaced arrangements and radially projecting teeth portion 54, and the teeth portion 54 is used
It is engaged in the chain 1.This second embodiment compresses the chain 1 using the guiding element 5 of different shapes, provides another light
The selection of the tensioning apparatus of quantization.
Refering to Fig. 5, a 3rd embodiment of the tensioning apparatus of chain 1 of the present invention, substantially with the structure of the second embodiment
Identical, be different in: 5 position of guiding element of this third embodiment is to be placed within the scope of 1 corral of the chain goes out, and is supported
It is against the inside of chain slack list, therefore the elastic force of the stretch section 3 can push the guiding element 5 from top to bottom, that is, by 1 slack list of chain
The direction in inside toward outside pushes the chain 1, and the chain 1 is made to maintain certain tensioning degree.
By the different structure design of this third embodiment, it is mountable to the different location of car body 10.Therefore the present invention is set
10 structure of car body that different styles can be cooperated on meter promotes degree flexible in application, and the guide wheel 5 is located at 1 corral of the chain and goes out
Within the scope of, it can avoid being collided or being kicked by foreign object.
Only as described above, only the embodiment of the present invention is all when cannot be limited the scope of implementation of the present invention with this
It is all still to belong to the present invention according to simple equivalent changes and modifications made by scope of the present invention patent and patent specification content
In the range of patent covers.
