The main lock core key and the auxiliary lock core key are imbedded on both sides of the keytainer; thereby the auxiliary lock core can be unlocked by the auxiliary lock core key, and the main lock core hole can be uncovered, then the main lock core can be unlocked the main lock core key, thereby realizing an better effect of space saving and easy to use.

Description

Combined type key

Technical field

The utility model relates to a kind of combined type key.

Background technology

The main switch of conventional locomotive is equipped with main core, and inserts main lock core hole with the tabular key of bar (being the key of so-called 2D) and pull to separate, but because main lock core hole exposes, the apprentice of the thieves or robbers who act under cover of night is easy to the hand-held tool insertion and destroys main core, causes anti-theft effect very poor.In recent years then the main core of some locomotive changes key (being the key of so-called 3D) with spar-type, though be not easy to crack, but main lock core hole still exposes, and some thieves or robbers who act under cover of night's apprentice still can attempt destroying, and do not go adrift by sheer good luck, but because main lock core hole is destroyed, cause the car owner can't unblank on the contrary, and must ask the master worker that repairs of motor supply shop to go out to change lockset, very inconvenient, also very expensive, equally still dangerous.Therefore, just have with the lockset of another form lock and pull and cover main lock core hole, but must unblank respectively to separate to pull with the key of two kinds of forms, can open main switch so that the user to be provided higher safety, in this case, the user must carry two keys, take up space very much, also very inconvenient.

The utility model content

The purpose of this utility model is to provide a kind of combined type key that can open major and minor core with a key respectively.

For achieving the above object, technical solution of the present utility model is: a kind of combined type key, comprise main core key, key cover, secondary core key, wherein respectively be provided with a caulking groove in the key cover opposite end, this two caulking groove is build-in master's core key and secondary core key respectively.

The caulking groove place of this key cover is provided with screw, and screw threaded is in screw packing core key.

After adopting such scheme, because the utility model is distinguished build-in in the corresponding caulking groove of key cover with main core key and secondary core key, constitute one combined type key, can reach with same complex key, earlier separate the secondary core of pulling with secondary core key, and expose main lock core hole, separate the main core of pulling with main core key again, thereby reach than save space and enhancement effect easy to use.

In addition, the utility model also can be provided with screw at the caulking groove place of key cover, and fitted bolt is screwed together in screw and packing master core key again, thereby reaches the enhancement effect of replaceable key.

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 4, the complex key 1 of the utility model first embodiment is collocation main lock 2, secondary lock 3, secondary core 4, shield 5, cap 6 and implement, wherein:

Complex key 1 comprises main core key 11, key cover 12 and secondary core key 13; Main core key 11 is provided with dull and stereotyped key section 111, secondary core key 13 is provided with column key 131, and respectively be provided with a caulking groove 121,122 in key cover 12 opposite ends, and difference build-in master's core key 11 and secondary core key 13, key cover 12 stage casings are provided with the central slotted eye 132 of slotted eye 123 with the secondary core key 13 of correspondence in addition.

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

Secondary lock 3 is provided with the through hole 31 of a corresponding main lock core hole 211, and other is provided with tank 32 holding secondary core 4, and tank 32 comprises vertical slot 321 and the chute 322 that is connected, and also is provided with on the secondary lock 3 to keep away groove 30 and lug 34.

Secondary core 4 comprises slide block 41, screen 42, lock pin 43 and flexible member 432 thereof, pin pearl 44 and flexible member 441 thereof, slide block 41 is provided with post groove 411 and traverse furrow 412, traverse furrow 412 is communicated with post groove 411 and is embedded screen 42, the through hole 413 that post groove 411 bottom communication aperture are less, baffle ring 431 is established in lock pin 43 stage casings, and lock pin 43 is behind 431 times sheathed its flexible members 432 of baffle ring, be arranged in again in the post groove 411 of slide block 41, and flexible member 432 two ends of lock pin 43 are butted on post groove 411 diapires on baffle ring 431 and the through hole 413 respectively,

pin pearl

44 and 441 of flexible members thereof just are contained in the vertical slot 321 of

secondary lock

3,41 of slide blocks are contained in the chute 322, and pin pearl 44 corresponding lock pins 43, and lock pin 43 is subjected to its flexible member 432 to replace baffle ring 431 and screen 42, its ejection force supports to pin pearl 44 again, pin pearl 44 also is subjected to its flexible member 441 to replace and support to lock pin 43, and pin pearl 44 partly exposes when lock is pulled state outside the vertical slot 321 and stretches into the through hole 413 under the post groove 411 of slide block 41 and block slide block 41, make slide block 41 slide and lock and pull, and be equipped with a long handle 414 on the slide block 41 of secondary core 4 in addition, this long handle 414 hold and slippage in keeping away groove 33, long handle 414 is provided with projection 415.

Shield 5 has the handle 51 of screening, and be articulated in a pivot hole 53 on the lug 34 of secondary lock 3, and shield 5 is provided with a chute 52 in addition, and the projection 415 embedding cunnings on the long handle 414 of slide block 41 are in the chute 52 of shield 5, thus interlock shield 5 and hide handle 51 and cover main lock core hole 211.
