Abstract

The utility model relates to a safety lock, containing a lock head body with a lock core; wherein the lock head body has a through hole and a bolt to facilitate mounting. The utility model is characterized in that: the outer of the lock head body has a lock head panel which is provided with a lock core hole in the center and a through hole opposite to the through hole of the lock head body; an inner rotor plate is positioned between the lock head panel and the lock head body, the center of which has a lock core hole with a protruding component; the inner rotor plate also has a nick opposite to the through hole of the lock head panel; and the head of the lock core has a concave position in which the inner rotor plate is positioned, thus the inner rotor plate rotates with the lock core. The safety lock is safe and artistic.

Description

Safety lock

Technical field:

The utility model is relevant with lock, particularly a kind of Safety lock.

Background technology:

General only from the installation of the lock of outdoor use key unlocking, the outdoor screw that lock is installed of always having hidden, but the lock that all must open the lock with the key for the indoor and outdoor, still can will install for outdoor one side with screw concealed, and from indoor, this mounting screw then comes into plain view, and does not have the people of key to want to open the door, utilize that screwdriver is very light just can be opened door, thus safe not enough.

Summary of the invention:

Problem to be solved in the utility model is the deficiency that overcomes above-mentioned prior art, provide a kind of Safety lock, the screw concealed of tapered end is installed, from outdoor or all tapered end can't be unloaded from the indoor screwdriver that only utilizes, must just can unblank with key, to guarantee safety.

Technical solution of the present utility model is as follows:

A kind of Safety lock, comprise the tapered end that contains lock core, tapered end is provided with for through hole and the screw installed, be characterized in that the outer button of this tapered end is provided with the tapered end panel, this tapered end face plate center is provided with lock core hole, is provided with corresponding through hole corresponding to the lead to the hole site of tapered end, between this tapered end panel and tapered end, also be provided with rotor in, the center of rotor also is provided with lock core hole in being somebody's turn to do, and this lock core hole has a protuberance, and interior rotor is provided with and the corresponding breach of the through hole of tapered end panel; Termination, lock core place is provided with recess, and the protuberance of interior rotor embeds the recess of lock core, and rotor rotatablely moves with lock core in making.

Number of openings on the said tapered end is 2, and the breach of its through hole and interior rotor all is symmetrically distributed about lock core.

The specific embodiment:

See also Fig. 1 to Fig. 7, Fig. 1 is the utility model Safety lock preferred embodiment structure cross-sectional schematic.The utility model Safety lock is by tapered end panel 1, interior rotor 4, lock core 2, tapered end 3 constitutes, lock core 2 is arranged in the lock core hole of tapered end 3, these tapered end 3 outer buttons are provided with tapered end panel 1, this tapered end panel 1 center is provided with lock core hole 11, through hole 31 positions that wear screw 32 corresponding to tapered end 3 are provided with corresponding through hole 12, between this tapered end panel 1 and tapered end 3, also be provided with rotor 4 in, the center of rotor 4 also is provided with lock core hole 41 in being somebody's turn to do, there is a protuberance 42 at the edge of this lock core hole 41, have through hole 12 corresponding breach 43 on the interior rotor 4 with tapered end panel 1, lock core 2 terminations are provided with recess 22, the recess 22 that the protuberance 42 of interior rotor 4 embeds lock core 2 (be cannot see this recess 22 and protuberance 42 from the end face of lock core 2, (as shown in Figure 2), interior rotor 4 will be rotatablely moved with lock core 2.

Fig. 2 is the right view of Fig. 1 Safety lock, and the state after promptly key is extracted, interior the rotor 4 fixedly head of the screw 32 of tapered end shelter from, and not only at this moment attractive in appearance but also safety can't utilize screwdriver that tapered end is unloaded; When in the keyhole 21 that key is inserted lock core 2 and during half-twist, interior rotor 4 is followed lock core 2 rotations, at this moment the breach 43 of rotor 4 is aimed at the through hole 31 of tapered end 3 and the through hole 12 of tapered end panel 1 in making just, as shown in Figure 3, can see the head of two hold-down screws 32, this state just can utilize screwdriver to mount and dismount tapered end.Fig. 4 is the structural representation of tapered end panel 1, Fig. 5 is the structural representation of interior rotor 4, Fig. 6 is the right view that removes Safety lock behind the tapered end panel, and Fig. 7 is the right view of the utility model Safety lock when removing the tapered end panel and key being inserted the lock core half-twist.

In sum, the advantage of the utility model Safety lock is just can unblank with key, no matter all be hidden at indoor or outdoors because the screw of tapered end is installed, only utilize screwdriver tapered end can't be unloaded, need could mount and dismount hold-down screw with key.Thereby it is safer.
