The main purpose of the present invention is to provide a key structure (2). The key includes: a key body including a handle portion and a rod portion, wherein the rod portion protrudes from the handle portion by at least two joint wings and The conical end is integrally formed by the free end of the connecting wing, so that a hollow groove is formed between the connecting wing and the conical end, the conical end is provided with a central perforation, and the handle is provided with a set of holes corresponding to the central perforation. a hole; at least one of the embryos is cylindrical, and the embryos are recessed in the outer ring surface with a ring groove of different depths, and a central shaft hole is provided, and the outer diameter of the pieces is placed In the hollow groove of the key body rod portion; a positioning pin is fixed by the central perforation of the conical end of the key body, penetrates the embryo block and is inserted into the sleeve hole of the handle, and fixes the embryo block to the key In the hollow groove of the body rod.

According to the key structure (2) disclosed in the present invention, the aperture of the central shaft hole of the blast block is the same as the central perforation hole of the conical end, and the outer diameter of the blast block is just equal to the bottom of the conical end.

According to the key structure (2) disclosed in the present invention, the outer end surface of the rod connecting wing of the key body may also form a row of bead grooves.

The key structure (2) disclosed in the present invention, wherein the key body of the key body connecting portion between the connecting wing and the conical end can also form at least one reinforcing strip connecting the two connecting wings.

The key structure (2) disclosed in the present invention, wherein the connecting wings of the key body stem portion can also be of various geometric shapes.

The key structure (2) disclosed in the present invention, wherein the blast block is a single cylinder, and the single block is embossed by a ring groove having a shallow depth and a concave surface.

The above-mentioned objects, structures and features of the present invention will be described in detail with reference to the preferred embodiments of the present invention. .

First, referring to the first to fourth figures, an embodiment of a key structure (2) of the present invention includes: a key body (10) comprising a handle (11) and a rod portion (12) Wherein the rod portion (12) is formed by extending at least two connecting wings (120) from the handle portion and integrally forming the conical end portion (121) from the free end of the connecting wing (120), so that the connecting wing (120) and the cone A hollow groove (122) is formed between the ends (121), the conical end (121) is provided with a central perforation (1210), and the handle (11) is provided with a set of holes corresponding to the central perforation (1210). (110); at least one blast block (20) is cylindrical, and the blast block (20) is concavely provided with a ring groove (21) having a shallow depth in the outer ring surface, and is provided with a central shaft hole (22). The outer diameter of the blast block (20) is placed in the hollow groove (122) of the stem portion (12) of the key body (10), and the aperture of the central shaft hole (22) and the conical end ( 121) The central perforation (1210) has the same aperture, and the outer diameter of the blasts (20) is exactly equal to the bottom of the conical end (121); a positioning pin (30) is provided by the key body (10) The central perforation (1210) of the conical tip (121) extends into the embossing (20) and is inserted It is fixed in the sleeve hole (110) of the handle (11), and the embryo block (20) is positioned in the hollow groove (122) of the rod portion (12) of the key body (10).

In the following, the structural features, technical means and expected effects of the present invention will be described in detail with reference to the drawings, and it is believed that the present invention can be more deeply and specifically understood as follows: Referring to Figures 5-7, it can be seen that the key of the present invention is mainly assembled in the hollow groove (122) of the stem portion (12) of the key body (10) by means of a cylindrical embryo block (20), and by the embryo The ring groove (21) with different shades of the outer ring surface of the block (20) is matched with the lock bead (31) of the lock core group (30) to achieve the purpose of opening and closing.

When implemented, as shown in the fifth figure, since the key stem of the present invention is composed of a cylindrical embryo block (20), and the ring groove (21) on the blast block (20) is designed to make the lock core group ( 40) The upper locking bead (41) is not limited in its positional arrangement. As long as there are at least the number of locking beads (41) corresponding to the number of annular grooves (21) on the blast block (20), the locking beads (41) can be set. In the radial position of the lock core (44) of the lock core group (40) and the outer ring portion, the difficulty of the anti-theft of the lock core group (40) can be increased.

In addition, the connecting portion (12) of the rod portion (12) of the key body (10) can be fixed by the embossing block (20), and the outer end surface thereof can also form a row of bead grooves (123) and a lock core group (40). The locking beads (42) correspond to each other, and the connecting wings (120) are further protruded from the blasting block (20), so that they can be toggled when inserted into the opposite locking holes (43) of the lock core group (40). The lock core (44) rotates without idling due to the cylindrical embryo block (20).

Furthermore, the key body (10) of the key body (10) is connected to the hollow groove (122) formed between the wing (120) and the conical end (121), and at least one reinforcing strip (124) may be formed to connect the two links. Wing (120), which is used to increase the strength of the key to the key (as shown in Figure 6).

The connecting wings (120) of the above-mentioned key body (10) rod portion (12) can also be of various geometric shapes (such as the seventh figure).

As shown in the eighth figure, the embryo block (20) of the present invention is an embodiment of a single cylinder, and the single column of the embryo block (20) is attached to the outer ring surface and has a different depth of the ring groove. (twenty one).

With the composition of the above components, if the user wants to reset the key, the correct arrangement of the ovule (20) and the ring groove (21) must be obtained, and the number of the blast block (20) and the ring groove of the present invention. (21) The depth of the module can be mass-produced and fixed by special tool machines with high precision due to the standardized design of the recoverable module, and the blast block (20) is fixed through the positioning pin (30). After that, it is impossible to exit, so the store must have the ring groove (21) number of the original blast block (20) to enable the user to process the bead groove (123) on the outer end surface of the connecting wing (120), so It does have the safety effect of preventing the key from being easily copied.

Moreover, since the present invention is a key stem composed of a cylindrical embryo block (20) having a ring-shaped groove (21), the lock beads (41) on the lock core group (40) can be arranged without being limited, thereby eliminating In addition to the difficulty of preventing theft of the lock core group (40), the design of the ring groove (21) plus the protruding joint wing (120) cannot be completed by the conventional copying machine, or the groove is completed. It is true that the security and economic value of the key as a whole can be achieved.

The present invention has been described with reference to the preferred embodiments of the present invention. However, those skilled in the art can change and modify the present invention without departing from the spirit and scope of the invention. Such changes and modifications shall be covered in the scope defined by the following patent application.

In summary, the present invention provides a key structure (2), which has indeed achieved all the objects of the present invention, and the spatial type of the combined structure is not found in the same type of products, nor has it been disclosed before the application, and has met the patent law. The provisions of the law, 提出 apply in accordance with the law.
