Description

Combined key

This creation is about a modular key.

With the development of society, the economic income of modern people has increased, and more attention has been paid to the hard and accumulated property. In addition to depositing property outside the bank, some people will store their belongings in the safe to avoid theft; the anti-theft measures of the safe are the most common. It is equipped with a lock. When the safe is opened, the key corresponding to the lock can be used. As long as the difficulty of opening the lock is increased, the risk of property being stolen can be reduced. The common key is an integrally formed structure, and the key is engraved with a tooth corresponding to the lock. When the key is inserted into the lock during use, the lock can be opened or locked. However, in actual situations, the key may be easily found to be stolen because it is not collected, which may cause the safe to be opened. Therefore, the key is a security loophole, even if the security is extremely high, the lock cannot be directly protected against others. Use the key to unlock.

In view of the above problems, the main purpose of the present invention is to provide a combined key which can improve the difficulty of unlocking the lock and thereby improve the safety requirements.

In order to achieve the above object, the present invention provides a combination key, comprising at least a first key and a second key, the first key is provided with a first handle at one end and a first key body at the other end, the first key body Forming a first spoon portion; the second key is provided with a second handle at one end thereof. The other end is provided with a second key body, and the second key body is formed with a second spoon portion; wherein the first key and the second key are provided with corresponding joints and are detachably assembled with each other.

Therefore, in actual use, the first key and the second key need to be combined to form a complete key to perform the unlocking operation; and when not normally used, the keys can be separately stored in different positions to reduce each The risk that the key is found at the same time also means that as long as the first key and the second key are not found at the same time, the lock can not be unlocked, and this can increase the difficulty of unlocking, thereby improving the security anti-theft effect.

Figure 4 is an exploded view of the second embodiment of the creation.

The structural features of the present invention and the intended effects thereof are described in the following preferred embodiments, and are not intended to limit the scope of the present invention.

Referring to FIG. 1 and FIG. 2, the combined key of the present invention comprises a first key 1, a second key 2 and a third key 3.

The first key 1 is provided with a first handle 11 at one end and a first spoon 12 at the other end. The first body 12 is formed with a first spoon 121. The second key 2 is provided with a second handle 21 at one end and a second spoon 22 at the other end. The second body 22 is formed with a second spoon. The third key 3 has a third handle 31 at one end and a third spoon 32 at the other end. The spoon 32 is formed with a third spoon portion 321. The spoon portion is a hole-like structure in this embodiment, and the spoon portion may be a tooth shape, a groove, a cylinder or other shape structure that can be used for unlocking in other embodiments. The handle is for holding the hand, and the handle is preferably flat or has a certain thickness to facilitate gripping.

The first key 1, the second key 2 and the third key 3 are detachably connected to each other by a corresponding joint portion. In this embodiment, the joint portion of each key is a corresponding convex portion. 13 and 23 and the recessed portion 24, so that the keys of the respective convex portions and the concave portions can be positioned to each other, so that the keys are assembled with each other, and the first key body 12, the second key body 22 and the third key body 32 are both A triangular column shape, the three can be combined with each other in a cylindrical structure (the first spoon 12, the second spoon 22 and the third spoon 32 are simultaneously attached to the other two), and In other embodiments, the keys can be combined with each other by magnetic attraction, snapping, pressing, insertion, and the like.

Therefore, in actual use, the first key 1, the second key 2, and the third key 3 need to be combined to form a complete key, and the unlocking operation can also be performed; and when not normally used, each can be The keys are stored in different locations, reducing the risk of each key being found by others. Even if someone finds one of the keys, it can't be unlocked. It means that as long as the keys are not found at the same time, the unlocking action cannot be performed, and this can increase the unlocking. Difficulty, thereby improving the security and theft protection of the lock. In addition, after the keys are disassembled and separated, since each key has a key handle and a spoon, it means that each key can be used as a common key alone, and the utility model has good practicability.

It is worth mentioning that the non-limiting key of the creation needs to be in the above-mentioned manner, and the key can be designed in combination with the lock, as in the second embodiment (please refer to FIG. 3 and FIG. 4), the first key is 1. The second key 2 and the third key 3 are all in the form of a sheet and are superposed and detachably assembled with each other, each of the keys has a different length, and the second key 2 is sandwiched between the first key 1 and the third key 3 Each key is provided with corresponding bumps 25, 33 and card slots 14, 26 so as to be able to be coupled to each other, thereby enabling The flat key is combined to be used with another lock, and after the keys are separated, the keys can also be used as a common key.

Summarizing the above, the combined key of this creation is not only structurally innovative, but also highly progressive, in line with the relevant provisions of the Patent Law, and filed a patent application in accordance with the law, so that the Office of the Office can grant a patent as soon as possible.
