Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described in detail by embodiment.
Before this utility model is described in detail, it shall be noted that in the following description content,
Similar element is to be identically numbered to represent.
Refering to Fig. 2 to Fig. 4, this utility model can prevent the colored hub driver element that pawl comes off
One first embodiment, this colored hub driver element 100 that can prevent pawl from coming off is suitable for and is installed on
One colored hub 8 (as shown in Figure 4).
This flower hub 8 comprises 81, hub shell unit 82 of a single mandrel, and two side cover unit
83.This colored hub driver element 100 that can prevent pawl from coming off can utilize two bearings 10 and in
Can be rotatably mounted in this mandrel 81.
This colored hub driver element 100 that can prevent pawl from coming off comprises a body 1, multiple pulls
Pawl 2, multiple elastic component 3, and a stop part 4.
This body 1 extends along an axis L, and includes a pawl installation portion 11.This pawl
Installation portion 11 have one around this axis L the ring wall 12 that defines an external port 121,
And multiple are positioned at this ring wall 12 and are respectively provided with pulling of opening direction identical with this external port 121
Pawl installing hole 13.
Described pawl 2 is in being pivotally mounted at this pawl installation portion 11 respectively.Each bullet
Property part 3 is arranged at this pawl installation portion 11, and includes a circular groove being arranged in this ring wall 12
Portion 31, and one from this outward extending elastic in circular groove portion 31 32.Each elastic component 3
This elastic 32 there is the bullet that this pawl 2 that it is corresponding is radially outward supported by a perseverance
Property power.
One of them of aforementioned two described bearings 10 can be sheathed in one of this ring wall 12
On anchor ring 122.Remark additionally at this, owing to the inner ring surface 122 of this ring wall 12 is in system
Can be through Precision Machining (Precision Finishing) operation during making, so can have
It is beneficial to allow this inner ring surface 122 of the present utility model directly consolidate with this bearing 10 match.Separately
Outward, this ring wall 12 have one in contrast to this external port 121 and from this inner ring surface 122 towards this
The design of the shoulder 123 of axis L projection, also can allow this shoulder 123 for being positioned at this inner ring surface 122
On this bearing 10 support, in case this bearing 10 that stop bit is on this inner ring surface 122 occurs axle
To free situation.
This stop part 4 around this axis L, and include one can be by this external port 121 and energy
With the friction tight flange part of inner ring surface 122 41 of this ring wall 12, and one from this flange part 41
The block extended radially outwardly and can prevent described pawl 2 from coming off from described pawl installing hole 13
Portion 42.
In the present first embodiment, the flange part 41 of this stop part 4 is in whole loop.It addition,
The material of the flange part 41 of this stop part 4 can but be not limited to plastic material or metal material.
This utility model this can prevent colored hub driver element 100 that pawl comes off on assembling, first
After first described pawl 2 being respectively arranged in this ring wall 12 with described elastic component 3, and by one
This bearing 10 is directly sleeved on the inner ring surface 122 of this ring wall 12, then by this stop part 4
Flange part 41 is directly arranged at this inner ring surface 122 tightly, can quickly and easily complete
Assembling operation.
For the colored hub driver element 9 of this energy positioning pawl existing, this utility model
Have only to by the flange part 41 of this stop part 4 directly by this external port 121 and with this ring wall
After inner ring surface 122 tight fit of 12, the colored hub that just can remove this energy positioning pawl existing from drives
The described fixing post 942 of unit 9 must coordinate the most one by one with described fixing hole 914
Situation, thus promote this utility model convenience on assembling and versatility.
Even if it is noted that when the described elastic component of existing colored hub driver element is to use pressure
During the design of contracting spring, this utility model is the same can utilize the flange part 41 by this stop part 4
It is direct and this friction tight mode of connection of inner ring surface 122, and effectively prevents pawl to be axially disengaging.
Refering to Fig. 5, of colored hub driver element that pawl comes off can be prevented for this utility model
Second embodiment, this second embodiment is analogous to this first embodiment, this second embodiment with
The Main Differences of this first embodiment is:
This stop part 4 ' of the present utility model also includes multiple being distinguished into many by this flange part 41
The expansion joint 412 of individual section 411.It is preferred that described section 411 is in equiangularly arranged.
So, this second embodiment also can reach the purpose identical with this first embodiment above-mentioned with
Effect.
In sum, this utility model can prevent the colored hub driver element that pawl comes off, and really can
Reach the purpose of this utility model.
