Description

Three-dimensional is opened mechanical security door automatic locking

The utility model relates to a kind of lock, the Mechanical theft-proof door lock that particularly a kind of three-dimensional is opened.

At present, the mechanical security door automatic locking that the three-dimensional of selling on the market is opened, be by

1) seat big pile, middle pile, left pile arranged on the lid and bottom, go up pile, pile down, the member apertures that right wall has main dead bolt hole and external trepanning, upper wall to have to connect upper lock tongue, lower wall has and connects the lock housing that the lock of dead bolt member apertures down constitutes,

2) between big pile and middle pile, have at the bottom of the lock at the bottom of having footstalk to pass gear, lock below a gear and one, the compound gear that has the cam of dop to constitute above,

3) upper lock tongue and connectedly pass the parts that lock upper wall member apertures has rack and pinion coupling,

4) following dead bolt and connectedly pass the parts that lock lower wall member apertures has the rack and pinion coupling,

5) pass main dead bolt hole main dead bolt, pass the overcoat that contains movable dead bolt of external trepanning and connected at above-mentioned 2 above the tooth bar, joint pin, insurance hole, and rack and pinion coupling are arranged, shape parts between last pile and following pile,

6) end is enclosed within the other end on the big pile gib head and tack, is positioned at the self-lock rod in the cam outside, and the self-lock switch of the spring formation between self-lock rod and the lock left side wall,

7) two ends are enclosed within respectively on big pile and the middle pile, are positioned at self-lock switch and the lower platen above the compound gear,

8) be enclosed within on big pile and the middle pile, be fixed on again on the left pile, right-hand member has guide rod to reach the interior top board of main dead bolt,

9) end is enclosed within on the guide rod, and the other end heads on the spring at the bottom of the main dead bolt,

10) pass and be fixed on the top board, the tapered end that the dop driven gear that its inner is passed lower platen and had shift fork can stir cam rotates,

11) the left end downside has recessed hook to match with left pile, right-hand member connects end in contact behind a slanting baffle and the movable dead bolt, middle be rotatably connected on the bar of taking above the shape parts, and the activity that is connected joint pin and the axle extension spring formation to the connector between the recessed hook is had contact with by axle

12) on the cam footstalk of outside at the bottom of the lock, connect a knob,

13) on one side of knob, the discharge cock that can put in and withdraw from the insurance hole on the shape parts after the opening and closing by a corresponding lock is formed.

The gib head of the self-lock switch of this lock can only be equal with the inner surface at the bottom of the lock, and for keeping its flexibility of revolution, lower platen can not be pressed self-lock switch too tight again, keep certain clearance therebetween, but this is easy to make the self-lock rod of self-lock switch upwards to lift up, gap between making at the bottom of gib head and the lock increases, and the parts that cause being connected with following dead bolt pass from the gib head lower end, make self-lock switch malfunctioning.

The purpose of this utility model provides the mechanical security door automatic locking that a kind of three-dimensional that the parts that are connected with following dead bolt can't be passed under the gib head of self-lock switch is opened.

The purpose of this utility model realizes by following proposal: the gib head on the described self-lock switch self-lock rod that extends, being provided with one on the end of described lock is the center of circle with big pile, self-lock rod is the arcuate socket of radius, makes the gib head of described lengthening carry over arcuate socket within it and moves.

The gib head that extends on the described self-lock switch self-lock rod is equal with the external surface at the bottom of the lock in arcuate socket.

The utility model since extended on the self-lock rod gib head and at the bottom of the lock, be provided with an arcuate socket, the gib head of self-lock switch can move in arcuate socket, the length of gib head can be nearly doubled, even at this moment the gib head of self-lock switch has been lifted up, the parts that are connected with following dead bolt can not form the gap between gib head and the lock baseplane, so can't pass yet under the gib head of self-lock switch.The gib head of self-lock switch has strengthened the force intensity that is subjected to of gib head in arcuate socket simultaneously, and is not yielding, so also strengthened the pick-proof intensity of lock.This lock can't go wrong, and the market competitiveness is very strong.

The utility model is described in further detail below in conjunction with accompanying drawing.
