Description

A kind of novel door lock prevented from opal unlatching burglar-proof door

Technical field

The utility model belongs to theftproof lock field, particularly a kind of novel door lock prevented from opal unlatching burglar-proof door.

Background technology

Along with the continuous improvement of people's living standard, the security requirement of people to security door is more and more higher, the common security door now installed in the family, general all with an opal, if forget that professional technique or lawless people are then by this opal with key back locking, utilize special tool, by the handle on instrument pressing security door wainscot, just can open security door easily, cause very large danger to the person and property.

Summary of the invention

Technical assignment of the present utility model provides a kind of novel door lock prevented from opal unlatching burglar-proof door for above prior art deficiency.

The utility model solves the technical scheme that its technical problem adopts: a kind of novel door lock prevented from opal unlatching burglar-proof door, belong to theftproof lock field, comprise lock body, square bar rotating shaft, handle, knob and wainscot part, described square bar rotating shaft connects with handle, hole through wainscot is connected to lock body, described wainscot part is provided with clamp, clamp slideway, spring, pin rod, pin, described knob design is on wainscot, it is the switch that control clamp slides up and down, described clamp is arranged at wainscot inside, and clamp bottom is designed with U-shaped bayonet socket.

The common security door with opal now installed in the family, all can squeeze grip and open door on the wainscot of security door indoor, no matter be that there is people indoor or owner goes out, if forget and lock security door, some lawless people just can utilize special tool by opal, the handle on pressing security door wainscot, open security door easily, causing very large danger, the original intention of design of the present utility model to the person and property, is the generation taking precautions against this danger.

The crucial part of the utility model design principle is the application being clamp, described clamp can move up and down in clamp slideway, the motion of clamp is then by the control of rotary switch, described pin rod is arranged at inside knob, and with pin, both are fixedly connected with, act on clamp by pin rod during switching knob, described both ends of the spring is connected to inside knob and clamp top, when opening knob, under spring force, clamp moves downward, U-shaped bayonet socket just can block square bar rotating shaft, so just can not the switch of control gate by door handle, namely the possibility from opal unlatching burglar-proof door is prevented.

Detailed description of the invention

With reference to Figure of description, the utility model is described in detail below:

As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of novel door lock prevented from opal unlatching burglar-proof door, belong to theftproof lock field, comprise lock body 1, square bar rotating shaft 7, handle 10, knob 6 and wainscot 2 part, described square bar rotating shaft 7 connects with handle 10, hole through wainscot 2 is connected to lock body 1, described wainscot 2 part is provided with clamp 3, clamp slideway 9, spring 4, pin rod 5, pin 8, described knob 6 designs on wainscot 2, it is the switch that control clamp 3 slides up and down, it is inner that described clamp 3 is arranged at wainscot 2, clamp 3 bottom is designed with U-shaped bayonet socket, described clamp slideway 9, spring 4, pin rod 5, pin 8 and knob 6 acting in conjunction, be used for the motion of regulable control clamp 3.

The open theory of the common security door of family is, by swing handle 10, square bar rotating shaft 7 by force transmission to lock body 1, thus can security door be opened, if do not locked by security door, by the opal on security door, utilize special tool squeeze grip 10, just can open security door easily.

As shown in Figure 3, the novel door lock prevented from opal unlatching burglar-proof door designed by the utility model, clamp slideway 9 designs the both sides, inside at wainscot 2, for supporting sliding up and down of clamp 3, notch is had inside knob 6, pin rod 5 one end is positioned in notch, by pin 8, knob 6 and pin rod 5 are fixed together, spring 4 two ends are then be separately fixed at inside knob 6 and clamp 3 upper end, open knob 6, under the drive of knob 6, pin rod 5 is in extreme lower position, now spring 4 shrinks, clamp 3 is driven to move downward, U-shaped mouth below clamp blocks square bar rotating shaft 7, so just lock the rotation of square bar rotating shaft 7, now just security door can not be opened by handle 10, but do not affect household and open security door by key, no matter be that people is in or goes out, as long as open this function knob 6, just some unnecessary danger can be taken precautions against.

As shown in Figure 4, close knob 6, under the drive of knob 6, pin rod 5 turns to extreme higher position, and clamp 3, by jack-up, moves upward along clamp slideway 9, U-shaped bayonet socket leaves square bar rotating shaft 7, square bar rotating shaft 7 like this just can not be subject to the restriction of clamp 3, can freely rotate, and handle 10 also just can normally use.
