Abstract

Door lock unit has drive mechanism arranged as a rod with square cross-section interacting with holder. The utility model relates to locking units and can be used to install on outer door.

Description

The useful model refers to locking devices and can be used for installation on external doors.

The closest to the proposed model is the gate locking device, application of Great Britain Me2 174 453, ЕО5В 9/08, 55/06 /"reference magazine "Inventions of the world" Me7, 1985/

The device has a drive mechanism mounted inside the door and connected to the external controlled lock by a drive element that accommodates the catch between the extended and retracted positions. The lock is removably installed in the external drive element. The cylinder lock has a rotary plug.

The fastening device, which moves inward along the cylinder, turns together with the plug between the position of fixing the lock and the position of releasing the lock. The interacting device on the external drive element is disconnected from the fastening device when the latter is in the disengaged locking position. The key in the lock plug must be turned to the specified position to turn the plug with the fastening device.

The shortcomings of the prototype include a large number of operations for opening and closing the lock with a key (the need to use a cylinder mechanism for both opening and closing), as well as tightening the bolts into the housing directly by the cylinder mechanism leash, which increases the wear of the device and, thus reducing its reliability,

The basis of the useful model is the task of improving the yard locking device, in which the reliability of its operation and the ease of operation are increased by changing the design of the lock and the locking device as a whole.

The task is achieved in a device that has a drive mechanism mounted inside the door and connected to an externally controlled lock and a drive element connected to the handles, in which, according to the invention, the drive element is made in the form of a rod with a square section that interacts with a holder that accommodates a bolt of cylindrical shape, fixed on the holder, in addition, the device has a control body that includes two handles with pads, bushings and a fastening system that interacts with the drive element, handles mounted on bushings having a circular shape with square holes inside, with a square rod placed in them with the possibility of rotation around an axis, a body that accommodates a bolt with a holder and a catch, with a supporting bar attached to it with holes for bolts, a catch and a latch, overlays with holes for a two-cylinder locking mechanism and supplied with external latches, an external controlled lock in the form of a two-cylinder mechanism, placed symmetrically but in relation to the body, which contains a leash in the center, which interacts with the stop, with the possibility of moving and fixing the stop in the lower extreme position with the help of a lever pressed by a spring, which has

L-shaped, a square rod that interacts simultaneously with the handles, a ring having protrusions, and with a cam that contains depressions corresponding to these protrusions, and the protrusion located on the cam from above, when the lever is rotated, leads to a rectilinear movement of the holder with bolts , fixing them in the extreme position with the help of a lever, and the spring, fixed in the cover on the outside, returns the handles to the original /horizontal/ position.

In fig. 1 shows the declared door locking device in isometry / overlays and handles are shown separately

MO).

In fig. 2 shows the door locking device with the cover removed.

The device /fig. 1/ consists of a body 1, which has a box shape with holes for installing a two-cylinder mechanism 2, a cover C in the form of a plate, a control body that includes handles 4, pads 5, bushings 6, which interact with the drive element -- square rod 7.

The handles of the device are attached to bushings 6, which are securely installed in pads 5, which are tightened with screws 8. The pads have external latches 9, under which there are holes for the two-cylinder mechanism, and bushings, which are the support and transmission element of the handles.

The bolts 10 are firmly installed on the holder 21 /fig. 2/, which moves in the "open" position, and in the "closed" position serves as their fixator. Latch 11 and moves inside the case /position "open"/ together with the bolts under the action of the handle.

The supporting bar 12 has holes for a clip, latches, a latch 13 and fixing on the door. The latch 13 serves to prevent accidental closings. This is achieved by pressing it down as far as it will go.

The two-cylinder mechanism is securely installed inside the lock and has a leash in the middle that interacts with the stop 15 /fig.2/.

The principle of operation of the lock is as follows /fig. 2/: the key is inserted into the well of the two-cylinder mechanism /when the latch is open above the well/ and turns, while the leash 14 starts to move the stop 15, which moves straight down, thus creating a release of the bolts 10 /possibility tightening them in the middle of the case/, and the stop itself is fixed in the lower extreme position by the lever 16 with the help of the spring 17.

The bolts are tightened with the help of knobs 4 by turning them down by 30" to the /"open"/ position.

The action of the handles 4 on the bolt 10 and the catch 11 is carried out in the following sequence: the handle, acting on the sleeve 6, drives the square rod 7, which, in turn, drives the ring 18, which has protrusions.

The ring 18 acts on the cam 19, which rotates the lever 20, which moves the holder 21 in a straight line, which at the same time tightens the bolt 10. Simultaneously with the tightening of the bolts 10, the catch 11 is tightened and the stop 15 is released by turning the cam 19, which activates lever 22, which rectilinearly tightens the catch 11 and rotates the lever 16, which holds the stop 15 in the lowest position.

After that, the stop 15 takes an intermediate position, which determines the holder 21. After releasing the handles 4, they return to their original position under the action of the spring located in the pad 5, and the catch 11 at this time returns to its original position. At the same time, the bolts 10 are fixed. For additional fixing of the bolts 10, there is a latch 13, which moves in a straight line and has two extreme positions, fixed with the help of a spring 23. To turn the bolts 10 to the extended position, it is necessary to turn the handle 4 upwards, while rotating the square rod 7, which , in turn, rotates the ring 18 together with the cam 19. The cam 19 activates the lever 24, at the same time the holder 21 and the bolts 10 are unfixed and returned to the extended position under the action of the spring 25. The bolts are linearly extended from the housing of the locking device until the moment when they start to rest on the bar. After fixing the bolts 10 on the bar 12, the stop 15, which is in an intermediate position, moves straight up under the action of the spring 26, and fixes the bars 10 on the opposite side of the bar. After releasing the handles 4, they take the original /horizontal/ position under the action of the spring located in the cover.

The proposed design of the yard locking device allows, through its improvement, to increase the reliability of its operation and ease of operation.

This is achieved by the fact that the handle plays a significant role in the operation of this device. For the lock to be in the "closed" position, it is enough just to lift the handle up, which will lead to the release of the holder, and it will "close" the door together with the bolts under the pressure of the spring. At the same time, it is completely unnecessary to use a cylinder mechanism.

The reliability of the yard locking device is achieved by the fact that all its parts are made of metal, and high-quality hardened steel is used for the three bolts and the outer lining. and what and her 29 6 and now today and N ml, and peh is still and that me NNYA p times E and ohchna and o still NYA NDU zha shih derit ;
