The specific embodiment
As Fig. 3, Fig. 4, shown in Figure 5, the utility model pulls that folding formula key 30 has the operating body 31 that grasps for the user and in order to stretch into the insertion body 32 of lockset 20.
The insertion body 32 that the utility model is pulled folding formula key 30 is by the operate portions 321 that can stretch into lockset 20 and expose to lockset 20 connecting portion 322 outside and that articulate with operate portions 321.
Connecting portion 322 is fixedlyed connected with operating body 31, also can be one-body molded with operating body 31.So, can expose the connecting portion 322 of lockset 20 and operating body 31 and pull together and be converted into and lockset 20 external device (ED) faces inserting body 32, promptly 10 pipes of bicycle, the 11 surfaces structure kenel of developing causes interference so as to reducing the utility model to the user.
Because the utility model is pulled folding formula key 30 when reality is used, can be according to behavior in service, make the connecting portion 322 that inserts body 32 remain on same axial location with operate portions 321, allow the user be utilized operating body 31 normal rotation locksets 20, connecting portion 322 and operating body 31 are pulled be converted into the structural form that develops with lockset 20 external device (ED) faces where necessary.
Therefore, the operate portions 321 of inserting body 32 is respectively equipped with lead angle 331 with connecting portion 322 in the same side of mutual articulated section, and be provided with butting section 332 at the opposite side that corresponds to lead angle 331, in order to do allowing operate portions 321 and connecting portion 322 be able to pull folding towards a side that is provided with lead angle 331 smoothly, and restraint of labour portion 321 and connecting portion 322 towards the butting section side of 332 pull folding, thereby the structural feature that can allow the utility model be maintained fixed in use, and be unlikely to influence its normal function of use.
Even, can be further be provided with card pearl 341, locate 342 and make operate portions 321 and connecting portion 322 remain on second locating hole 343 of pulling the folding state and be provided with to embed so as to making operate portions 321 and connecting portion 322 remain on first of same axis for card pearl 341 in connecting portion 322 and card pearl 341 corresponding slide planes in the articulated section of operate portions 321 and connecting portion 322.So, can allow the utility model arrive user mode fast or pull the fixed position of folding state, to increase the convenience that uses.
Moreover the utility model pulls when folding formula key 30 is concrete to be implemented, and as Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, is provided with two folder ears 351 inserting body 32 operate portions 321; Connecting portion 322 is provided with correspondence and stretches into 321 two pivot ears 352 that press from both sides between the ear 351 of operate portions.
The connecting portion 322 that inserts body 32 stretches between two folder ears 351 of operate portions 321 with its pivot ear 352, and articulates by the trunnion 353 that is arranged on two folder ears 351 and the pivot ear 352, and can keep the whole whole property of inserting body 32.
In the present embodiment, promptly be provided in the same side of two folder ears 351 and pivot ear 352 corresponding trunnions 353 respectively so as to the lead angle 331 of connecting portion 322 and operate portions 321 being pulled smoothly folding, and two folder ears 351 are respectively equipped with butting section 332 equally with the pivot ear 352 corresponding opposite sides that are provided with lead angle 331, with restraint of labour portion 321 and connecting portion 322 towards the butting section side of 332 pull folding.
In addition, card pearl 341 is provided in two root position places between the folder ear 351, makes operate portions 321 and connecting portion 322 remain on first locating hole 342 of same axis and makes operate portions 321 and connecting portion 322 remain on the slide plane that second locating hole 343 of pulling the folding state is provided in pivot ear 352 and card different 341 as for being used to; Especially the root position of operate portions 321 between two folder ears 351 is provided with trepanning 344, and in trepanning 344, be provided with spring 345, card pearl 341 promptly is sheathed on the outside that trepanning 344 corresponds to spring 345, to block of the effect of pearl 341 normalities and can produce towards 352 ejections of pivot ear by spring 345, to allow card pearl 341 be fallen into first locating hole 342 or second locating hole 343 really, allow connecting portion 322 and operate portions 321 reach user mode fast or pull the fixed position of folding state.
What deserves to be mentioned is that the utility model is pulled folding formula key 30 in the specific implementation, be provided with lead angle 331 except corresponding to trunnion 353 the same sides at two folder ears 351 with pivot ear 352 respectively, to allow connecting portion 322 and operate portions 321 pull outside the folding smoothly; Also can all keep the gap between the root of two folder ears 351 and pivot ear 352 and between the root of pivot ear 352 and two folder ears 351, to avoid pulling the interference that causes connecting portion 322 and operate portions 321 when rolling over; As shown in Figure 5, the ora terminalis place that corresponds to trunnion 353 1 sides at pivot ear 352 is convexly equipped with cushion block 333, in order to do when connecting portion 322 and operate portions 321 are not pulled folding, can contact by the root of cushion block 333 with two folder ears 351, guarantee that connecting portion 322 and operate portions 321 are remained on same axis, and be unlikely to influence normal function of use of the present utility model.
As mentioned above, the utility model provides the preferable feasible folding formula of pulling key 30, is applicable to bicycle lock especially, and is when preventing that the user from driving bicycle, injured because of touching key.
