The specific embodiment

For technical problem, technical scheme and advantage that embodiment of the present utility model will be solved is clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.

See also Fig. 1 to Fig. 4, the utility model provides a kind of Double-actuating lock, and it is the Double-actuating lock with key lock mechanism and combination lock mechanism, and this Double-actuating lock includes a lock housing 1, a combination lock mechanism 2 and a key lock mechanism 3.

Lock housing 1 has panel 11 and the base 12 that corresponds to each other mutually and engage.Panel 11 is rectangle, and is provided with a perforation 111, and panel 11 surfaces are provided with several equidistant windows of arranging 112, and the inwall of panel 11 also convexes with several microscler retaining walls 113 between window 112.Base 12 is formed with another perforation 122 perforation 111 with respect to this panel 11, and convex with several equidistant elastic components of arranging 121 on the base 12, described elastic component 121 is that the suitable flexible materials of tool such as plastics or rubber are made, the end of each elastic component 121 is provided with a salient point 1211, described salient point 1211 compresses corresponding digit wheel 22 another ora terminalis faces, and avoids its dialing or rotate arbitrarily when not dialling.

Combination lock mechanism 2 is installed in the base 12, and to the direction of panel 11 push jack 21 and a plurality of digit wheel 22 are installed by base 12 in regular turn, and each digit wheel 22 respectively in regular turn pivot be with one take turns the cover 24, wear each digit wheel 22 and wheel cover 24 in together by a lock core rod 25 again, and be arranged with a spring 23 respectively between the wheel cover 24.

Push jack 21 can be formed by the bending of metal sheet integrated punching, what it was movable is installed in the base 12, and offer the port 211 of a plurality of equidistant arrangements, and push jack 21 extends the butting section 212 that is provided with a plurality of equidistant arrangements by the ora terminalis in the port 211 towards wheel cover 24, this butting section 212 takes the shape of the letter U, and cover 24 is taken turns against this in butting section 212.

Each digit wheel 22 1 end passes the port 211 of corresponding push jack 21 respectively, and the edge face manifests outside the window 112 of panel 11.In addition, wheel cover 24 1 ends respectively form circular lug 242 and a plurality of fin 2421 that extends to form on lug 242 edge faces that a planar portions 241, is formed at planar portions 241 lateral margins, and this lug 242 can be resisted against the retaining wall 113 on the panel 11.

The butting section 212 of push jack 21 lays respectively between the wheel cover 24, and the displaceable ora terminalis that is resisted against wheel cover 24, and each spring 23 two ends presses on butting section 212 and lug 242 respectively, so that each takes turns the flexible displacement of cover 24 tools, and the butting section 212 of push jack 21 can be resisted against on the lug 242 of adjacent wheel cover 24.

Digit wheel 22 inside are equipped with several grooves 221 respectively, and described fin 2421 can match with groove 221, so that digit wheel 22 each pivot cover are positioned at outside the wheel cover 24.

In addition, lock core rod 25 1 ends wear to base 12, and further are arranged with another spring 26, and the other end is formed with the holding part 251 of half sphere shape.Described spring 26 1 ends press on base 12 inner faces, and the other end presses on the butting section 212 of push jack 21.

Key lock mechanism 3 wears this lock housing 1 and combination lock mechanism 2, and corresponds to the perforation 111 of panel 11, has the function of general key lock.Say that further key lock mechanism 3 has to be assembled a core 31, a lock barrel sleeve 32, sheathed and that can rotate respectively each other in regular turn and protrude from the outer torq 33 and of panel 11 and be hubbed at handle 34 on the torq 33.And core 31 has a keyhole 311, and core 31 edge faces are provided with and are positioned at two symmetrical flat faces 312 of same rotate path and two arc surfaces 313, and correspond to an end of push jack 21, so that core 31 is when rotating, flat face 312 and arc surface 313 can be connected to an end of push jack 21 respectively, make push jack 21 can produce displacement.And core 31 rear ends extend out to outside the base 12, and then can connect a strike plate (figure does not show).And the active force that can utilize above-mentioned spring 26 makes push jack 21 can flexibly be back to original position, can promote adjacent wheel cover 24 by butting section 212 simultaneously and reset.

Lock barrel sleeve 32 edge are towards the interior chute 321 that is equipped with a camber shape, and two mutual correspondences are arranged at the hole 322 in the chute 321, and the holding part 251 of above-mentioned lock core rod 25 is placed in chute 321 and this hole 322 movably.

See also Fig. 4, when manipulating, when the user stirs digit wheel 22, but driven wheel cover 24 begins to rotate, and digit wheel 22 promptly goes to the planar portions 241 of wheel cover 24 when going to correct number, this moment swing handle 34, make under wheel cover 24 the active force and leave retaining wall 113, also make fin 2421 leave the groove 221 of digit wheel 22 by spring 23.

See also Fig. 5 to Fig. 7, and please cooperate and consult Fig. 2, further specify operation of the present utility model.When the user inserts correct key, key inserts in the keyhole 311 of core 31, and this moment, push jack 21 was on the flat face 312 of butt core 31 originally, when key drives core 31, push jack 21 promptly is connected on the arc surface 313, and produces displacement, and core 31 can drive strike plate simultaneously and unblanks.When the user again key drive core 31, push jack 21 can contact the flat face 312 of core 31 again, and displacement once more, core 31 drives the strike plate lockings simultaneously.In addition, when the user forgets the correct number of combination lock mechanism 2, also can use key turns key latch mechanism 3 to make push jack 21 displacements, know correct number via rotating digit wheel 22 again.

Double-actuating lock of the present utility model can provide the user to utilize correct key or utilize correct number, can unblank, and avoids the operator not carry key or forgets number, and can't unblank.Many protection together are provided simultaneously, when being in unlocking condition, dial arbitrarily random number character wheel 22 and can't change number, and digit wheel 22 that must combination lock mechanism 2 goes to correct number and just can lock or the number of establishing again, can prevent effectively that strongbox from being locked by other people or be changed number.

The above is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
