Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As depicted in figs. 1 and 2, the utility model provides a kind of trailing wheel flower-drum of bicycle, including internal is hollow knot
The left and right ends of the bicycle beam barrel 1 of structure, the bicycle beam barrel 1 are both provided with spoke installation disk 2, the spoke installation circle
It is provided with several left mounting grooves 3 on 2 left side of disk, several right mounting grooves 4, the left mounting groove 3 and the right side are provided on right side
It is both provided with hollow steel pipe 5 and limiting and protecting device 6 in mounting groove 4, connecting rod 7, the company are provided in the hollow steel pipe 5
7 one end of extension bar is connect by damping spring 8 with hollow steel pipe 5, and the other end extends to 5 outside of hollow steel pipe, and is provided with spoke
Mounting ring 9, spoke mounting ring 9 are used for installing bicycle spoke, realize between the bicycle rear flower-drum and bicycle rear
Connection.
Work as bicycle to playing the role of bumper and absorbing shock in bicycle spoke operational process by the way that damping spring 8 is arranged
On bump course when driving, bicycle spoke for a long time can damage bicycle spoke by external force, shorten bicycle
The service life of trailing wheel flower-drum, the setting of damping spring 8 can pass through connecting rod when bicycle spoke is by tension or pressure
7, under the telescopic action of damping spring 8, the balanced action to external force is realized, to reduce bicycle spoke institute stress, to certainly
Driving spoke plays the role of protection.
The setting of limiting and protecting device 6 plays the role of protection to bicycle spoke, prevents the excessive shape of bicycle spoke
Become, it, can be under the effect of damping spring 8, to spoke if bicycle spoke is under pressure when bicycle spoke is by ambient pressure
Item installs 2 center movement of disk, and at this time if effect without limiting and protecting device 6, bicycle spoke can pacify to spoke always
The change that 2 center of dress disk is subjected to displacement, this will cause the excessive deformation of bicycle spoke, occur so as to cause bicycle spoke
Damage bending, is also possible to directly scrap when serious, cannot be used continuously, this just brings more troubles to user.
The limiting and protecting device 6 includes that limit lantern ring 601 and several limit strips 602, the limit lantern ring 601 are located at
Between spoke mounting ring 9 and hollow steel pipe 5, and connecting rod 7 slides through 601 center of limit lantern ring, limits corresponding on lantern ring 601
Be provided on the end face of spoke mounting ring 9 it is several partly wear limit hole 603, it is blind hole partly to wear limit hole 603, not completely through
Lantern ring 601 is limited, the setting of limit strip 602 is between limit lantern ring 601 and spoke mounting ring 9, and the company of being uniformly arranged on
The outer surface of extension bar 7, the position one-to-one correspondence partly worn limit hole 603 and limit strip 602, limit strip 602 can be half
It wears free to slide in limit hole 603.
The operation principle of limiting and protecting device 6 is as follows：
Under the effect of damping spring 8, connecting rod 7 drives bicycle spoke to install 2 center movement of disk, limit to spoke
Strip 602 can be run to partly wearing in limit hole 603, and blocking can be played the role of to limit strip 602 by limiting lantern ring 601, be kept away
Exempting from connecting rod 7 drives bicycle spoke to be excessively subjected to displacement deformation to 2 center of spoke installation disk, partly wears the length of limit hole 603
Degree is the deformable distance of bicycle spoke, to play the role of protection to bicycle spoke.
The left mounting groove 3 and right mounting groove 4 are radially arranged each along 2 surface of spoke installation disk, and 3 He of left mounting groove
The one end of right mounting groove 4 far from 2 center of spoke installation disk all extends to the periphery that spoke installs disk 2, to facilitate certainly
Drive a vehicle spoke installation, the left mounting groove 3 and right mounting groove 4 being radially arranged so that bicycle spoke Impact direction be along
Spoke installs the radial direction of disk 2, to ensure that bicycle spoke uniform force so that cycling is better；
The left mounting groove 3 and right mounting groove 4 are symmetrical about spoke installation disk 2, i.e., left mounting groove and right mounting groove are in space
Upper arranged in a crossed manner, left mounting groove 3 and right mounting groove 4 arranged in a crossed manner may make on 2 two sides of spoke installation disk
The state of cross arrangement is presented in bicycle spoke, and force analysis is it is found that the bicycle spoke of two intersections so that the flower-drum is held
The power of load is less than the dynamics that the bicycle spoke that two are mutually parallel makes the flower-drum be undertaken, so as to mitigate flower-drum significantly
The power born plays the role of protection to the flower-drum, extends the service life of flower-drum.
The sum of twice of limit 602 height of strip and the diameter of connecting rod 7 are more than limit 601 central diameter of lantern ring,
But less than limit 601 central diameter of lantern ring and partly wear limit hole 603 height and, on the one hand, ensure that limit lantern ring 601 it is right
The barrier effect for limiting strip 602 avoids the occurrence of limit strip 602 and is not required to wear limit hole 603 through more than half, you can directly from limit
The center of lantern ring 601 moves freely, i.e., the limiting and protecting device 6 is ineffective；On the other hand, it is ensured that limit strip 602 can
It is moved partly wearing in limit hole 603, avoids partly wearing limit hole 603 since the height of limit strip 602 in the vertical direction is higher than
Height in the vertical direction causes connecting rod 7 that can not move, i.e., damping spring 8 is ineffective.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing in the equivalent requirements of the claims will be fallen
All changes in justice and range are embraced therein.Any reference numeral in claim should not be considered as limitation
Involved claim.
