Description

The utility model refers to hardware and can be used to install electronic cylinder locks on the door leaf of buildings, apartments, offices.

Known cylinder lock plate, containing a housing with a central hole for installing the cylinder lock mechanism and a key hole, two plates installed on the door. The body has a rounded shape and has internal projections with holes that receive pins installed in the door. The inner part of the body, facing the door, is closed by a lid. The pins have grooves that accommodate the locking elements of the cylinder mechanism (RU 94027735 A1, E05C 7/04, publ. 27.04.1996).

The closest analogue is a cylinder lock plate containing a protective metal element and a decorative plate. The cover is equipped with a socket with a cavity into which the protective element is inserted. The protective element, cover plate and rosette are provided with coaxial holes for fastening by means of screws on the inner door leaf and a central hole for the cylinder mechanism. The protective element is installed inside the socket. The socket, made of plastic and installed inside the lining, has elastic elements (projections) by means of which it is connected to the decorative lining (RU 2370612 C1, E05B 15/02, publ. 20.10.2009).

Known linings are reliable and provide protection against burglary by unauthorized people. However, when using known linings for cylinder locks with electric motors to control the cylinder mechanism of the lock, sufficient reliability of the installation of cylinder locks is not ensured. When installing the electric motor on the pad, cyclic loads may occur during the operation of the electric motor and vibration due to the displacement of the axes of the electric motor and the cylinder mechanism of the lock, which can lead to damage to the cylinder mechanism of the lock and its failure.

The technical problem of the utility model is to create an overlay for a cylinder lock, which includes an electric motor to control the cylinder lock mechanism.

The technical result of the utility model is to increase reliability by reducing the influence of vibrations and cyclic loads on the elements of the lock when controlling the electric motor of the cylinder mechanism.

The specified technical result is achieved by the fact that in the cover plate of the electronic cylinder lock, containing the mounting plate, a decorative cover plate, in which holes are made for attaching to the inner door leaf by means of screws and a hole for the cylinder mechanism, a rotary coupling for installing the electric motor housing of the cylinder mechanism on the decorative cover plate on the lateral surface of the rotary sleeve, there are annular protrusions for installation in the corresponding annular grooves made in the inner cavity of the central hole of the decorative strip facing the swivel clutch, the lateral surface of which is provided with protrusions shifted around the circumference in the mounting plate and the decorative strip on the end surfaces facing to the rotary coupling, grooves are made into which the protrusions of the rotary coupling are inserted, the lateral surface of the decorative strip is equipped with grooves located perpendicular to the protrusions of the rotary coupling for fixing it in the decorative slope adhered with locking screws screwed into square nuts located in the rectangular grooves of the decorative strip.

Fig. 8 is a spatial view of the patch.

The cover plate of the electronic cylinder lock contains a decorative cover plate 1, a rotary sleeve 2 for installing the motor housing 3 (not shown in the drawing) and a mounting plate 4 (Figs. 2, 8). The rotary clutch 2 has a rounded shape, on the lateral surface of which there are protrusions 5 (Fig. 3) and annular protrusions 6 on the side facing the decorative strip 1. The protrusions 5 are located around the circumference of the lateral surface of the clutch 2.

The decorative strip 1 is attached to the mounting plate 4 (Fig. 2) using screws 7. In the mounting plate 4 and the strip 1, holes are made (Figs. 4, 5, 6, 7) for fastening to the inner door leaf by means of screws. An opening 8 for the cylinder mechanism is made in the mounting plate 4 and on the side of the cover 1 facing it. On the opposite side of the lining 1, a central hole 9 is made with annular grooves 10 for installing the rotary coupling 2. In the lining 1 and in the mounting plate 4, longitudinal grooves 11 are made (Figs. 5, 6), corresponding to the protrusions 5 of the coupling 2. In the lining 1, perpendicular to the projections 5 of the coupling, grooves 12 are made (Fig. 6, 7) for fixing the coupling 2 in the lining 1 with the help of locking screws 13 screwed into square nuts 14 located in the rectangular grooves 15 of the decorative lining 1. On the case 3 there is a USB connector 16 for supplying power to the electric motor when controlling the cylinder mechanism of the lock, and buttons 17 "OPEN" "CLOSE" Installation of the lining on the door from the inside is carried out as follows. A mounting plate 4, made, for example, in the form of a metal washer, is mounted on the inner door leaf using screws. The decorative cover 1 is attached to the mounting plate 4 and to the inner door leaf through the holes 8 in the mounting plate 4 and the cover plate 1 by means of screws (for example, self-tapping screws). The swivel sleeve 2 with the electric motor previously fixed to it is inserted into the ring grooves 10 of the cover plate 1 and by turning with projections 5, the coupling 2 is installed in the longitudinal grooves 11 of the lining 1 until it stops and is secured with locking screws 13 located in the grooves 12 made on the side surface of the lining 1 perpendicular to the projections 5 of the coupling 2. The locking screws 13 are screwed into square nuts 14 located in rectangular grooves 15 decorative lining 1. The depth of fixing the coupling into the longitudinal grooves of the decorative lining can be changed by changing the width of the annular grooves 11. To supply power to the electric motor on the housing is located by connector 16. On the lining there are buttons 17 "OPEN" "CLOSE", which allow you to control the opening / closing the door manually.

The electric motor is controlled using a control panel such as a mobile phone. A centering element is installed in the hole of the lining for the cylinder mechanism. If the pin of the cylinder mechanism has a sufficient length, such that the housing of the mechanism is recessed into the door leaf, pre-marking for fastening with a centering element is carried out, after which it is removed and installed as described above.

With such an installation of the device, the reliability of the installation of the cylinder mechanism of the lock is increased by reducing the influence of vibrations and cyclic loads on the elements of the lock when controlling the electric motor of the cylinder mechanism.
