RU177731U1 - CYLINDER LOCK MECHANISM - Google Patents

Abstract

The utility model relates to locking devices of increased secrecy, in particular to the design of the cylinder mechanism of the lock. The problem solved by the proposed design is the ease of disassembly and assembly of the cylinder mechanism of the lock. The cylinder lock mechanism comprises a housing. A cylindrical core with a keyway is rotatably disposed inside the housing. The rotation of the cylindrical core can be transmitted to the cam, designed to interact with the bolt of the lock. Coaxial pin holes are made in the housing and the cylindrical core. In these holes, code pins and support pins are sequentially placed. The support pins are spring-loaded, which are supported by threaded plugs. Threaded plugs are made in the form of screws 7, usually without a head. A thread is formed in the pin holes of the body for engaging with threaded plugs. In the proposed design, screws with an internal hexagon, an internal straight or crosswise slot can be used. 3 s.p. f-ly, 2 ill.

Description

The technical field to which the utility model relates.

The utility model relates to locking devices of increased secrecy, in particular, to the design of the cylinder mechanism of the lock.

State of the art

The prior art there are many designs of cylinder lock mechanism. As a rule, the cylinder mechanism consists of a body, two cylindrical cores and a cam. Both cores are connected by a kuplung and work together with a cam. Coaxial cylindrical pin holes are made in the housing and cores, in which the code pins and support pins are placed, as well as springs based on plugs that are pressed into the specified pin holes. The support pins perform the locking function, keeping the core from turning in the closed position. Code pins form a “code” for a given cylinder mechanism. When a key is inserted into the cylinder mechanism, all the code pins are placed on the line of the core and the cylinder body connector so that all the support pins are in the case. Thus, when turning the key, the core has the ability to rotate. The key, which engages with the kupung, rotates the cam, which drives the actuator of the lock.

A similar design is known, for example, from the description of utility model RU 133553, published October 20, 2013.

In the presented form, the cylinder mechanism is non-separable. For example, to replace the pins and springs, drilling of the plugs will be required, which can be implemented using special equipment. In this case, the probability of damage to the springs and pins is high.

Utility Model Disclosure

The problem solved by the proposed utility model is the creation of a collapsible cylinder mechanism.

This problem is solved due to the fact that a thread is formed in the pin holes of the cylinder mechanism housing, designed to interact with plugs made in the form of screws without a head, while the cylinder lock mechanism comprises a housing with a cylindrical core placed therein with the possibility of rotation with a keyway , in the body and the cylindrical core, coaxial pin holes are made with the code and supporting spring-loaded pins placed in them, and the springs are supported by plugs.

For ease of assembly and disassembly, the screws can be made with an internal hexagon, with an internal slot, or with a cross-shaped slot.

Thus, it becomes possible to easily assemble and disassemble the cylinder mechanism to replace pins and springs in case of repair, transcoding and creation of master systems.

Brief Description of the Drawings

The utility model is illustrated by drawings, in which:

in FIG. 1 shows the construction of a cylinder lock mechanism;

in FIG. 2 shows the design of the cylinder mechanism of the lock with plug holes for the pin holes made in the form of screws without a head with an internal hexagon.

Utility Model Implementation

The device is as follows. The main elements of the cylinder lock mechanism are shown in FIG. 1. The cylinder lock mechanism comprises a housing 1. Inside the housing 1, a cylindrical core 2 with a keyway is rotatably disposed. The rotation of the cylindrical core 2 can be transmitted to the cam 3, designed to interact with the bolt of the lock. Coaxial pin holes are made in the housing 1 and the cylindrical core 2. In these holes, the code pins 4 and the support pins are sequentially placed. The support pins 5 are spring-loaded with springs 6, which are supported by threaded plugs. Threaded plugs are made in the form of screws 7, usually without a head. A thread is formed in the pin holes of the housing 1 for engaging with threaded plugs.

In the proposed design, screws with an internal hexagon, an internal straight or crosswise slot can be used.

If necessary, the screws are unscrewed and the corresponding elements located in the pin holes are replaced.
