Description

composite key

technical field

The utility model relates to a composite key.

Background technique

The main switch of a traditional locomotive is equipped with a main lock core, and a strip-shaped key (the so-called 2D key) is inserted into the main lock core hole to release the switch. The tool is inserted to destroy the main lock core, resulting in poor anti-theft effect. Recently, the main lock cylinder of some motorcycles has been changed to a pole-type key (the so-called 3D key). Although it is not easy to crack, the main lock cylinder hole is still exposed. It was stolen, but because the main keyhole has been damaged, the owner of the car cannot unlock it, and has to ask a mechanic from the motorcycle shop to go out to change the lock, which is very inconvenient and expensive, and it is also unsafe. Therefore, there is another form of lock that locks and covers the main lock core hole, but the key of the two forms must be unlocked and released separately before the main switch can be opened to provide higher security for the user. Now, the user must carry two keys, which takes up a lot of space and is inconvenient.

Utility model content

The purpose of the utility model is to provide a compound key which can respectively open the main and auxiliary lock cores with one key.

In order to achieve the above purpose, the technical solution of the utility model is: a composite key, including a main lock core key, a key cover, and a secondary lock core key, wherein an embedded groove is provided in the opposite ends of the key cover, and the two embedded The grooves are respectively embedded with the key of the main lock core and the key of the auxiliary lock core.

The embedding groove of the key cover is provided with screw holes, and the bolts are screwed into the screw holes to tighten the lock core key.

After adopting the above scheme, since the utility model embeds the key of the main lock core and the key of the auxiliary lock core respectively in the corresponding slots of the key cover to form a composite key, it can be achieved with the same composite key, first with the auxiliary lock core. The cylinder key unlocks the auxiliary cylinder to expose the main cylinder hole, and then the main cylinder key is used to unlock the main cylinder, thereby achieving the enhanced effect of saving space and being convenient to use.

In addition, the utility model can also be provided with a screw hole at the insertion groove of the key cover, and then the bolt is screwed into the screw hole to tighten the key of the main lock core, thereby achieving the enhanced effect of the replaceable key.

Detailed ways

As shown in Figure 1, Figure 2 and Figure 4, the composite key 1 of the first embodiment of the present utility model is implemented by matching the main lock seat 2, the auxiliary lock seat 3, the auxiliary lock core 4, the shielding plate 5, and the cap 6. ,in:

Composite key 1, comprises main cylinder key 11, key cover 12 and secondary lock cylinder key 13; Each end is provided with a socket 121 , 122 , and the main cylinder key 11 and the auxiliary cylinder key 13 are embedded respectively.

The main lock base 2 has a main lock core 21 , and the main lock core 21 has a main lock core hole 211 , and the secondary lock base 3 is fixed on the main lock base 2 .

The auxiliary lock base 3 is provided with a through hole 31 corresponding to the main lock core hole 211, and is also provided with a container 32 to accommodate the auxiliary lock core 4, and the container 32 includes a vertical groove 321 and a sliding groove 322 connected to each other. The auxiliary lock base 3 Avoidance grooves 30 and lugs 34 are also provided on the top.

The auxiliary lock core 4 includes a slider 41, a grid plate 42, a lock pin 43 and its elastic element 432, a pin bead 44 and its elastic element 441, the slider 41 is provided with a column groove 411 and a transverse groove 412, and the transverse groove 412 and the column groove 411 communicates with and embeds grid plate 42, and column groove 411 bottom is communicated with the through hole 413 with smaller aperture, and lock pin 43 middle section is provided with retaining ring 431, and lock pin 43 sets its elastic element 432 under retaining ring 431, and then It is installed in the column groove 411 of the slider 41, and the two ends of the elastic element 432 of the lock pin 43 are respectively against the bottom wall of the column groove 411 on the retaining ring 431 and the through hole 413, and the pin ball 44 and its elastic element 441 are just in place. It is accommodated in the vertical groove 321 of the auxiliary lock seat 3, the slider 41 is accommodated in the chute 322, and the pin ball 44 corresponds to the lock pin 43, and the lock pin 43 is pressed against the stop ring 431 and the grid plate 42 by its elastic element 432 , its pushing force is then against the pin bead 44, and the pin bead 44 is also pushed against by its elastic element 441 and then against the lock pin 43, and when the pin bead 44 is in the locked state, part of it is exposed outside the vertical groove 321 and extends into the slide. The through hole 413 under the column groove 411 of the block 41 blocks the slider 41, so that the slider 41 cannot slide and is locked, and the slider 41 of the auxiliary lock core 4 is provided with a long handle 414 in addition, and the long handle 414 The long handle 414 is provided with a boss 415 for receiving and sliding in the avoidance groove 33 .

The shielding plate 5 has a shielding handle 51, and is pivotally connected to the lug 34 of the auxiliary lock seat 3 by a pivot hole 53, and the shielding plate 5 is further provided with a slide groove 52, and the protrusion 415 on the long handle 414 of the slider 41 It slides in the slide groove 52 of the shielding plate 5 , so that the shielding plate 5 is interlocked and the shielding handle 51 shields the main lock core hole 211 .

The cap 6 is provided with a lock core hole 61 and a slide groove 62 , the lock core hole 61 corresponds to the main lock core hole 211 , and the slide groove 62 corresponds to the slider 41 of the auxiliary lock core 4 .
