Description

flip key

technical field

The utility model belongs to a key, in particular to a flip key.

Background technique

As shown in Fig. 1 and Fig. 2, generally, the built-in lock 20' of the existing bicycle 10 is arranged at the position of the seat tube 11 close to the axis of the pedal 12, so as to achieve the purpose of locking the bicycle 10 by restricting the movement of the pedal 12. Purpose.

The similar built-in lock 20' used by the bicycle 10 has a unique design, that is, when the lock 20' is in the unlocked state, the key 30' must be inserted into the lock 20' to keep the key 30' in the lock 20'. The key 30' can be pulled out only when it is in a locked state.

Such design considerations, in addition to allowing the user to ride the bicycle without storing the key 30' in another place when riding the bicycle, and allowing the user to ride the bicycle easily, in some cases, the owner must show the key 30' In order to prove that the bicycle 10 is stolen in the locked state, the responsibility of the insurance claim can be clarified.

When the above-mentioned lock 20' is in the unlocked state, the key 30' is still designed to be inserted into the lock 20', although it has the convenience that the user does not need to store the key 30' in addition. However, in actual use, the exposed position of the key 30 ′ from the lock 20 ′ will cause considerable interference to the user, especially when the lock 20 ′ is arranged at an active position close to the pedal 12 , the key 30 ′ will interfere with the user. The interference problem becomes more obvious, and it may not affect the action of the pedal 12, but it may cause damage to the user's foot due to the exposed part of the key 30' during the actual riding of the bicycle.

Detailed ways

As shown in FIG. 3 , FIG. 4 , and FIG. 5 , the folding key 30 of the present invention has an operating body 31 for the user to grasp and an insertion body 32 for extending into the lock 20 .

The inserting body 32 of the flip key 30 of the present invention consists of a working part 321 that can extend into the lock 20 and a connecting part 322 that is exposed outside the lock 20 and pivotally connected with the working part 321 .

The connecting portion 322 is fixedly connected to the operating body 31 , and can also be integrally formed with the operating body 31 . In this way, the connecting portion 322 of the insert body 32 exposed to the lock 20 can be folded together with the operating body 31 into a structure that is flat against the surface of the external device of the lock 20, that is, the surface of the seat tube 11 of the bicycle 10, thereby reducing the impact of the utility model. User interference.

Since the folding key 30 of the present invention is actually used, the connecting part 322 of the insertion body 32 and the working part 321 can be kept at the same axial position according to the usage conditions, so that the user can use the operating body 31 to rotate the lock 20 normally, When necessary, the connecting portion 322 and the operating body 31 are folded into a structure that is flat against the external device surface of the lock 20 .

Therefore, the working portion 321 and the connecting portion 322 of the insertion body 32 are respectively provided with chamfers 331 on the same side of the mutual pivot joint, and are provided with an abutment portion 332 on the other side corresponding to the chamfers 331, so as to allow working The part 321 and the connecting part 322 can be smoothly folded toward the side provided with the chamfer 331, and the working part 321 and the connecting part 322 are restricted from being folded toward the side of the abutting part 332, so that the utility model can be kept in use when in use. Fixed structural shape, so as not to affect its normal use and function.

Even, a bead 341 can be further provided at the pivotal joint between the working part 321 and the connecting part 322, and a sliding surface corresponding to the connecting part 322 and the bead 341 is provided for the bead 341 to be embedded so that the working part 321 can be connected with the bead 341. The first positioning 342 for keeping the part 322 on the same axis and the second positioning hole 343 for keeping the working part 321 and the connecting part 322 in a folded state. In this way, the utility model can quickly reach the fixed-point position of the use state or the folded state, so as to increase the convenience of use.

Furthermore, when the utility model pull key 30 is implemented, as shown in Fig. 4, Fig. 5, Fig. 6 and Fig. 7, the working part 321 of the insert body 32 is provided with two clip ears 351; the connecting part 322 is provided with corresponding And extend into the pivot ear 352 between the two clip ears 351 of the working part 321 .

The connecting part 322 of the insertion body 32 extends between the two clip ears 351 of the working part 321 with its pivot ear 352, and is pivotally connected by the pivot pin 353 passing through the two clip ears 351 and the pivot ear 352, and The integrity of the integral insert 32 can be maintained.

In this embodiment, the guide angle 331 for smoothly folding the connecting portion 322 and the working portion 321 is arranged on the same side of the two clip ears 351 and the corresponding pivot pins 353 of the pivot ears 352, and the two clips The other side of the ear 351 and the pivot ear 352 corresponding to the guide angle 331 are also respectively provided with the abutting portion 332 to restrict the working portion 321 and the connecting portion 322 from being folded toward one side of the abutting portion 332 .

In addition, the clamping ball 341 is arranged at the root position between the two clip ears 351. As for the first positioning hole 342 used to keep the working part 321 and the connecting part 322 on the same axis and make the working part 321 and the connecting part 322 The second positioning hole 343 kept in the folded state is arranged on the sliding surface of the pivot ear 352 and the card 341; especially the working part 321 is provided with a sleeve hole 344 at the root position between the two clamp ears 351, and the sleeve hole 344 is provided with a spring 345, and the snap ball 341 is sleeved on the outer side of the sleeve hole 344 corresponding to the spring 345, and the spring 345 can push the snap ball 341 towards the pivot ear 352 normally, so that the snap ball 341 can Surely fall into the first positioning hole 342 or the second positioning hole 343, so that the connecting part 322 and the working part 321 can quickly reach the fixed point position of the use state or the folded state.

It is worth mentioning that, during the actual implementation of the folding key 30 of the present invention, in addition to providing a chamfer 331 on the same side of the two clip ears 351 and the pivot ear 352 corresponding to the pivot pin 353, so that the connecting part 322 and the working part 321 are smoothly folded; also, a gap can be maintained between the roots of the two clip ears 351 and the pivot ears 352 and between the pivot ears 352 and the roots of the two clip ears 351, so as to avoid folding. Cause the interference between the connecting part 322 and the working part 321; When folding, the pads 333 can be in contact with the roots of the two clip ears 351 to ensure that the connecting portion 322 and the working portion 321 are kept on the same axis without affecting the normal function of the utility model.

As mentioned above, the utility model provides a preferable and feasible flip-type key 30 , which is especially suitable for bicycle locks to prevent the user from being injured by touching the key when riding a bicycle.
