Abstract
The utility model relates to an anti-theft safety door lock device. In the utility model, a locking latch can be controlled to do lateral movement through the rotation of a rotary block in a lock core to control the rotation of a rotary disc. As a result, the rotary table can be controlled to drive a main inserted link, an upper inserted link and a lower inserted link to be locked, opened and closed between a door and a door frame. Thus the utility model can be locked in multiple directions, and can have the advantages of high safety, hard prying and strong anti-theft function. The utility model solves the problems of singe direction locking, weak mechanical performance, etc. of the existing door lock.
Description
The utility model relates to a last used antitheft locking device.
At present, it is simple, thin that a large amount of door locks that use all exist frame for movement, is unable to undergo to beat, prize, and is easy to be opened, and particularly these locks all adopt the locking mechanism in an orientation, are absolutely unsafe, and do not reach the requirement of safety standard.
The purpose of this utility model will overcome above-mentioned defective exactly, and the performance that designs a mechanism is strong, the device that can multi-facetedly lock.
The technical solution of the utility model:
One lock is set on door, its major technique feature be lock be provided with one locking latch, lock has a rotating spin-block on the back side, the one side contacts with the block of locking on the latch when normally hanging down, slide block on the locking latch is arranged on the limiting bracket that links into an integrated entity with lock, one rotating disk is arranged on door, limiting bracket and on slide block be stuck in indentation, there on the rotating disk, rotating shaft on the rotating disk is supported on the door, the rotating shaft two ends are connected with handle respectively, be connected with main inserted link connecting rod on the disk edge respectively, the upper plunger connecting rod, the lower plunger connecting rod, main inserted link connecting rod, the upper plunger connecting rod, the lower plunger connecting rod connects main inserted link respectively, upper plunger, lower plunger has corresponding with it main inserted link hole on the doorframe, the upper plunger hole, the lower plunger hole.
Advantage of the present utility model and effect are that mechanical performance is strong, are difficult to pry open door lock in the long duration, add multi-faceted locking, are difficult for especially opening, and play fabulous antitheft effect, stop stolen possibility, maintain social stability.
Accompanying drawing:
Fig. 1--the utility model principle schematic.
Fig. 2--the utility model scheme of installation.
Embodiment:
As shown in Figure 1, lock 17 is installed on the door 18, and what lock in this example 17 adopted is the cross Anti-drilling lockwork, and the back basifacial of lock 17 has locking latch 1, and the upper rear portion of lock 17 has spin-block 2, can left-right rotation 360 degree, and the one side contacts with backing pin 3 on locking latch 1; Lock 17 is fixedlyed connected with limiting bracket 4, slide block 19 on the locking latch 1 is on limiting bracket 4 tops, but locking latch 1 move left and right, in the middle of the rotating disk 10 is rotating shaft 15, rotating shaft 15 is installed on the door 18, the two ends of rotating shaft 15 are handles 16, be connected with main inserted link connecting rod 11, upper plunger connecting rod 14, lower plunger connecting rod 7 on rotating disk 10 edges respectively, they connect main inserted link 12, upper plunger 13, lower plunger 6 again respectively, they are parallel moving in the main inserted link hole 21 on doorframe 20, upper plunger hole 22, the lower plunger hole 23 respectively, and rotating disk 10 is connected with limiting bracket 4 by spring 5; An outstanding alignment pin 9 is arranged on the rotating disk 10, fastening screw 8 is arranged in its lower section, fastening screw 8 is installed on the door 18, but fastening screw 8 move left and right.As shown in Figure 2, on the doorframe 20 that hinge one side is arranged, be provided with two fixedly round pins 24, on the door 18 corresponding with it circular hole 25 arranged.
During work, as shown in Figure 1, towards seeking for a side in the door 18.In from the outside, open lock 17, when opening cross lock core, spin-block 2 clockwise rotates 360 degree, push the backing pin 3 on the locking latch 1 open, locking latch 1 is moved to the left, driving its slide block 19 on limiting bracket 4 also is moved to the left, leave the breach of rotating disk 10, holding handle 16 (outdoors) then is rotated counterclockwise, driving rotating disk 10 also rotates counterclockwise, the main inserted link connecting rod 11 that connects on rotating disk 10 edges like this, upper plunger connecting rod 14, lower plunger connecting rod 7 also drives main inserted link 12 with the rotation of rotating disk 10, upper plunger 13, lower plunger 6 is done parallel moving, break away from main inserted link hole 21, upper plunger hole 22, lower plunger hole 23, door 18 is opened at this moment, when door 18 1 sides are opened, as shown in Figure 2, round pin 24 on the doorframe 20 just in time leaves the circular hole 25 on the door 18 gradually, and door 18 is opened release handle 16 fully, rotating disk 10 clockwise rotates under the effect of spring 5, returns to original position.When needs close to the doorstep 18 in door 18, must in door 18, press lower handles 16 clockwise earlier, door 18 is fixed on the fastening screw 8 on 18 by also moving right after shutting in door 18, block the alignment pin 9 on the rotating disk 10, and rotating disk 10 must not be rotated; When needs are locked a door outside door 18 18 the time, also lower handle 16 must be pressed counterclockwise earlier, the door 18 that closes, release handle 16, then with the cross lock core on the key turns lock 17, spin-block 2 is rotated counterclockwise 360 degree, promotes the backing pin 3 on the locking latch 1, makes locking latch 1 move from left to right, driving its slide block 19 on limiting bracket 4 moves right, be stuck in the indentation, there of rotating disk 10, rotating disk 10 maintains static, and door 18 is by lock is firm up hill and dale.If from locking 17 doors 18 of not opening, and desire is pried open hinge from the door 18 and the hinge connection of doorframe 20 and since on the doorframe 20 two fixedly round pin 24 be inserted on the door 18 in corresponding two circular holes 25, door 18 is not still opened.
