Description

Key embryo improvement

This creation is about a kind of key embryo improvement, especially a kind of key embryo improvement with a right-angled right angle limit, so as to achieve anti-smashing and anti-theft opening effect.

In order to improve the ease of the user to insert the key into the keyhole to unlock the lock, the general locker usually makes the four corners of the key lever body as inclined slopes, so that the gap of the key insertion can be increased, and the gap pair is increased. When assembling a lock, or when a user inserts a key into a keyhole, it can bring a lot of convenience at an early stage; but for a long time, when the key and the keyhole are repeatedly inserted and rubbed, the gap between the contact faces is It will become more and more accommodative. After the insertion point, it is often difficult to accurately touch the opening line of the locking bead, which makes the unlocking become difficult and unsmooth, so it is forced to change the lock body early; in addition, the gap between the key and the keyhole is once When it gets bigger, the trouble comes, because the excessive gap will provide enough lock space for the lock that was originally installed for theft purpose, and it will not be able to perform its proper function.

In response to the above-mentioned shortcomings, the industry has introduced various kinds of lock embryo structures. For example, the TW M430510 patent case is that the case uses the groove of the key lever body to make the chute and the vertical groove coexist, which can solve the aforementioned problems, but it is Unfortunately, the previous case ignored the friction between the lock embryo and the keyhole, mainly at the four corners of the rod. Once the edge is out of alignment or the gap is enlarged, the groove at the central position is inevitably unable to accurately align. So the problem still exists and it has not really been effectively resolved.

In view of the lack of the formula, the creator of this case has finally completed this creation after numerous research and improvement, that is, the purpose of this creation is to provide a key embryo improvement with a right-angled right-angle limit to achieve flood prevention. And the effect of anti-theft.

For the purpose of the above-mentioned creation, the creation key embryo is provided with a first active surface and a second active surface on both sides of a rod body, and the first active surface and the second active surface are respectively provided with a plurality of a locking bead corresponding slot and a plurality of limiting action portions, wherein: the upper and lower ends of the first and second acting surfaces are located at a position near the center line, and each of the limiting portions is disposed at a right angle to the end side of the rod body In conjunction with the configuration of the corresponding groove of the locking bead, the structure is such that the rod body is formed with multiple limit positions, and the insertion of the limit key is mandatory, thereby achieving the effect of preventing the anti-theft opening.

Referring to the first to third figures, the structure of the key embryo 1 of the present invention is provided with a first active surface 11 and a second active surface 12 on both sides of a rod body 10, the first active surface 11 and the second active surface 12 are respectively provided with a plurality of locking bead corresponding slots 114, 115, 124, 125, and a plurality of limiting action portions 111, 112, 113, 116, 121, 122, 123, 126, characterized in that The upper and lower ends of the first and second acting surfaces 11 and 12 are located at the position of the near center line, and each of the limiting action portions 113 and 123 is formed at a right angle to the end sides 13 and 14 of the rod body 10, and the locking beads are matched. Corresponding to the arrangement of the slots 114, 115, 124, and 125, the structure of the rod body 10 is formed into multiple limits, thereby forcibly inserting the limit key, thereby achieving the effect of preventing theft.

The first action surface 11 has a locking bead corresponding groove 114, 115 and a limiting action portion 111, 112, 113, 116, and the second active surface 12 has a ball-locking corresponding groove 124, 125 and a limiting action portion 121. The 122, 123, and 126 are arranged in opposite directions, so that the user can insert the key into the lock hole to unlock the door without selecting the direction.

In the above-mentioned rod body 10, the end faces 13, 14 are provided with a guiding slope 117, 127 corresponding to the relative positions of the right-angle limiting action portions 113, 123.

The plurality of locking beads correspond to the grooves 114, 124, at least one of which is a straight groove.

The plurality of locking beads described above correspond to the grooves 115, 125, at least one of which is a trapezoidal groove.

With the composition of the above structure, the present invention utilizes the rod body 10 to have right-angle limiting action portions 113, 123 at the near center line position, and the straight groove and trapezoidal groove design of the corresponding ball-shaped corresponding grooves 114, 124, 115, 125. , the formation of multiple limit, with the mandatory limit of the insertion of the key, in order to achieve the effect of anti-theft anti-theft, effectively solve the missing key of the prototype key embryo.

In summary, the structure of this creation can solve the lack of the prototype key embryo, so as to achieve the effect of anti-mite and anti-theft, so this creation is unique to the novelty, utilization and progressiveness of the patent.

The specific embodiments set forth in the present disclosure are merely for convenience of explanation of the technical content of the present invention, and the present invention is not limited to the above embodiments, and does not exceed the spirit of the present invention and the following patent application scope. In the case of the changes Implementation is still within the scope of this creation.
