Abstract
The utility model discloses a many safeties door lock of breech changes exposed hasp into hidden in the past, inlays the long breech lock promptly and adorns in the door wing, distributes in the four borders of door, and links through pin and shifting block and spring bolt. The structure ensures that the lock tongue drives the long lock bolt to lock the four frames of the door wing, the anti-collision and anti-prying capabilities are strong, the exposed part of the lock bolt is few, and the safety and safety performance are greatly improved.
Description
The utility model relates to the improvement of many lock bolts door lock.
People be overcome general door lock can only be on a position opposite house wing carry out the defective of locking, proposed to utilize link gear simultaneously on the opposite house wing two or three different positions carry out the structure of locking, but such structural element is various, transmission is complicated, and the lock bolt on the diverse location exposes to the surface of a wing, and crashproof ability is still not ideal enough.The utility model is at number of patent application: further improve forming on 95228016.7 the basis.
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of many lock bolts lock door wing simultaneously is provided, many door bolts more insurance portal lock that the pick-proof crashworthiness is strong.
The purpose of this utility model is achieved by the following technical solution: fasten the more insurance portal lock with a bolt or latch more, by lock body, be loaded on the oblique dead bolt in the lock body, two round dead bolt, the shifting part of dead bolt interlock, two round tongue lock core, justify the formations such as shifting block that the tongue lock cores cooperate transmission with two, special feature is that long lock bolt is flush-mounted in four frames that a wing is interior, be distributed in a wing, and by pin and shifting block and dead bolt interlock.Further, the door wing long lock bolt on one side is by pin and the fastening interlock of two circle dead bolts; The long lock bolt on other limits of the door wing is hinged by pin and shifting block.
Adopt said structure, the locking of two round tongue lock cores drives the long lock bolt locking of Men Yisi frame, and four direction is all locked up and down, and is crashproof, the pick-proof ability is strong, and long lock bolt is flush-mounted in the wing, and exposed parts has seldom more improved the safety performance of door lock.
Below in conjunction with drawings and Examples the utility model is further elaborated.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to partial view;
Fig. 3 is the B-B sectional view of Fig. 1.
With reference to Fig. 1, in the lock body 11 of present embodiment triple lock cores are housed altogether, about the advance and retreat position of two round tongue lock cores 6, be furnished with nine lock cores 5, Spring cylinder lock core 10 respectively.Nine dead bolts 4 and hoodle dead bolt can snap on the stroke of two circle dead bolts 2, therefore, have only nine lock cores 5 and Spring cylinder lock core 10 to be in opening, could pass through keyhole 7 with two round tongue lock cores 6 unlatchings.
Except that shifting part 3 being housed to drive the oblique dead bolt 1, also be connected (as shown in Figure 2) by pin 14 and long lock bolt 12 on two round dead bolts 2, long lock bolt 12 is flush-mounted in the inside of a wing 13, so pin 14 also is interspersed in the groove 15 between a wing 13 and the lock body 11.Like this, two round dead bolts 2 and long lock bolt 12 interlocks, insert in the left-hand door frame in the hole that seco duration lock bolt 12 passes on the wing 13.
The rear portion of two round dead bolts 2 is connected with the approximate slide block sleeve of shifting block 8 formation, and the advance and retreat of two round dead bolts 2 can drive shifting block 8 and produce swing, and shifting block 8 is hinged by pin 9 and long lock bolt 12, and long lock bolt 12 is flush-mounted in the inside (as shown in Figure 3) of a wing 13.When the drive lower swing certain angle of shifting block 8 at two round dead bolts 2, the long lock bolt 12 on the both direction just inserts in the last lower door frame of the door wing 13 up and down, in the right doorframe of 12 insertion wings 13 of the long lock bolt on the right side.Like this, a block action of two round dead bolts 2 just locks four frames of the door wing 13 by long lock bolt 12, and lock bolt do not expose, not only firmly but also safety.
