Abstract

The utility model relates to an anti-force non-damage lock cylinder which is matched with all classes of locksets and belongs to the technical field of a hardware tool. A concave-convex quiescence fixing point is arranged on the upper plane of an outer cylinder body of the lock cylinder. A lock cylinder fixing body is arranged beneath a cap ring of the lock cylinder fixing body and clings to a fixing cover of the cap ring of the lock cylinder fixing body. A copper flat shim and a spring shim are arranged in the lock cylinder fixing body, and the spring shim is installed beneath the copper flat shim which is positioned beneath the outer cylinder body of the lock cylinder. An inner cylinder body of the lock cylinder is arranged in the outer cylinder body of the lock cylinder. The structure of the utility model is simple, compact and reasonable. Because a lock cylinder keyhole and a positioning pin are in the covert state, a key is hard for drilling and opening, checking teeth, drawing the teeth and matched with the teeth to enter the space. Robbers judge the concrete shape, the angle, the deepness and the size of the keyhole with difficulty, so the robbers can not select an appropriate prizing item to put into the keyhole. Because the outer cylinder body has a function of dissociation, the robbers can not obtain the purpose of prizing the lock cylinder. Thus, the loss of the lockset being stolen is avoided.

Description

The anti-harmless lock core of violence

Technical field

The utility model relates to the harmless lock core of a kind of anti-violence, specifically is used for and the supporting use of all kinds of locksets, belongs to the hardware ﹠ tools technical field.

Background technology

Before the utility model was made, in prior art, traditional lock core mainly was made up of inner core-body and external core two parts.The spring tooth of similar number is housed in the inner core-body cavity, adopts lock core dowel to fix external core, and be anchored on fully in lock body or the tapered end, have the inner core-body rotation to reach the sealed purpose of direct or indirect unlatching.The lock core of this kind structure has the motion space, vertical angle of view big because the spoon mouth exposes, and is easily colluded tooth, takes out tooth, joins the non-original key unlatching of tooth; Fix external core because of lock core adopts alignment pin, easily opened being subjected to prizing under the thing heavy attack by sled; Because lock core generally adopts the copper product manufacturing, its intensity enough causes easily in the spoon mouth lock core brill being opened with reamer or Charge) by the thief.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of lock core keyhole to be in hidden state, is difficult to have in the spoon mouthful bore open, collude tooth, take out tooth, join the space of tooth; The robber is difficult to judge concrete profile, angle, the degree of depth and the size of keyhole, can't select suitable sled thing to put into keyhole, and does not reach the purpose of opening key fully, avoids the harmless lock core of anti-violence of the stolen loss of lockset.

Main solution of the present utility model is achieved in that

The utility model mainly adopts lock core protective cover 1 to be installed in lock core spoon mouth the place ahead and lock core fixed body decorative cover fixed cover 12 connects into integral body; journey hole, key road 2 is arranged on lock core protective cover 1 upper side; lock core fixed body decorative cover 3 is set in lock core protective cover 1; and be positioned at lock core external core 11 tops; feature is to be provided with concavo-convex stationary fixing point 4 on plane on the lock core external core 11; lock core fixed body 5 is arranged on lock core fixed body decorative cover 3 belows; and be close to lock core fixed body decorative cover fixed cover 12; copper flat shim 6 and spring shim 7 are housed in lock core fixed body 5; spring shim 7 is contained in copper flat shim 6 belows; copper flat shim 6 is positioned at below the lock core external core 11, and lock core inner core-body 10 is set in lock core external core 11.

Compared with the prior art the utility model has the following advantages:

The utility model is simple, compact and reasonable for structure; Because the lock core keyhole is in hidden state, makes key be difficult to bore and open, collude tooth, take out tooth, join tooth and enter the space; The robber is difficult to judge concrete profile, angle, the degree of depth and the size of keyhole, can't select suitable sled thing to put into keyhole and pass through and change Qi Daocheng, again because of external core has free function, and does not reach the purpose of prizing the core that undoes the lock, and avoids the stolen loss of lockset.

The specific embodiment

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

The utility model mainly is made up of lock core protective cover 1, journey hole, key road 2, lock core fixed body decorative cover 3, concavo-convex stationary fixing point 4, lock core fixed body 5, copper flat shim 6, spring shim 7, key 8, cut-off rule 9, lock core inner core-body 10, lock core external core 11 and lock core fixed body decorative cover fixed cover 12 etc.

The utility model mainly adopts lock core protective cover 1 to be installed in lock core spoon mouth the place ahead and lock core fixed body decorative cover fixed cover 12 connects into integral body; journey hole, key road 2 is arranged on lock core protective cover 1 upper side; lock core fixed body decorative cover 3 is set in lock core protective cover 1; and be positioned at lock core fixed body 5 and lock core external core 11 tops; on plane on the lock core external core 11, be provided with concavo-convex stationary fixing point 4; lock core fixed body 5 is arranged on lock core fixed body decorative cover 3 belows; and be close to lock core fixed body decorative cover fixed cover 12; copper flat shim 6 and spring shim 7 are housed in lock core fixed body 5; spring shim 7 is contained in copper flat shim 6 belows; copper flat shim 6 is positioned at below the lock core external core 11; copper flat shim 6 can be done rotation arbitrarily in lock core fixed body 5, and can move down.Cut-off rule 9 tops are lock core protective cover 1, and the below is that lock core fixed body decorative cover fixed cover 12 is fastenedly connected with lock core fixed body 5.Lock core inner core-body 10 is set in lock core external core 11, and it can rotate, but also adopts alignment pin fixedly to place restrictions on.

Operating principle of the present utility model:

The utility model is because lock core adopts the twist-type telescopic inner core-body, external core is in " suspension " state in fixed body, no alignment pin is completely fixed in the fixed body, under certain twisting resistance effect, can do the rotation arbitrarily of 360 degree, but external core is close to fixed cover under spring upwards acts on, and stable being in the concavo-convex fixed point of circle, only just can reach purpose directly sealed and that open under the original key non-resistance is opened.

The utility model is owing to adopt the lock core of the above change of tens tooth rule, and it can be brought up to more than 1000 times, is equivalent to change the effect that spoon mouthful profile is reached more than 1000, and the lock core key blank of spoon mouth just of the same type just can change kind more than 1000.

The utility model can be combined into various types of locksets by actual needs, and key 8 is the utility model lock core profile.
