The mechanism is cylinder, larvae for locks: reviews, specifications

Safety, reliability and affordability are the main requirements for locking door devices made by customers. Due to its simplicity and versatility, the cylinder mechanism is successfully used by many manufacturers and is found on the market in a large assortment and various modifications.

Types and forms

Various types and installation methods make the cylinder lock universal, the selection of type is carried out depending on the material of the blade and the requirements for the operation and appearance of the door.

The cylinder mechanism has a standardized size, making it easy and quick to replace.

The form is a cylinder, but round, drop-shaped or triangular designs are also found.

Types of cylinder mechanisms: disk, pin, frame, magnetic or special with increased complexity.

Installation method:

• Mortise. It is installed in the hole made inside the case, if the canvas is continuous, or in the case of a hollow metal door is inserted into a special box, followed by front trim.
• Overhead. Installation is carried out directly on the outside of the door.

Structure

The cylinder mechanism for the lock consists of two main parts: cylinder and executive. Designed for moving and fixing door locks, the reliability of the entire system is ensured by the design feature of the secret mechanism.

Castle structure:

• The shell is most often made of brass, a mechanism is installed in it. The thicker the wall, the less likely it is to get to the filling from the outside of the door.
• Locking mechanism.
• Deadbolts (bolts) - fixing elements. In the closed position, they go into a special locking hole in the door frame. The quantity depends on the model and its degree of reliability.
• The bolt (latch) - an element that helps to keep the door in the closed position, enters the door frame body through the locking plate.
• Lever - provides a mechanism for locking / unlocking.
• The front face of the mortise lock is an attachment element, also has a decorative function.
• Locking plate - is installed on the door frame, has openings for bolts.
• The key is the element that starts the system.

Principle of operation

The system is simple, the key or latch-pinwheel rotate the tongue of the cylinder mechanism (lever), which starts the operation of the deadbolt. The standard size is only the width of the mechanism, the length is selected depending on the thickness of the door.

The cylinder mechanism for the lock is classified by the method of opening:

• The key works only from the outside; a rotary handle is provided on the back side - one-sided type.
• Turnkey holes on both sides of the door - double-sided type. The key / key cylinder mechanism is most often made of aluminum with a protective brass insert. Used for mortise types of locks.

Mechanism triggering

Any castle made or imported into Russia must have supporting documentation - a certificate of conformity and meet the requirements of GOST.

When choosing a cylinder mechanism for a lock, attention must be paid to its class, which depends on the response time (number of cycles worked).

To increase the protection of the larvae of the castle, many manufacturers: thicken the wall of the case, increase the number of structural elements of the mechanism. The materials used are: hardened, alloyed metals, as well as composite elements.

Hacking protection

The reliability of the anti-hacking depends on the class (I-IV) and is characterized by the time (min) required to destroy the main elements of the castle:

• Drilling a lock / privacy mechanism for I-IV class: 2; 5; 15; 30 minutes.
• Unscrewing the contents of the cylinder, for II-IV class: 50, 100, 250 Nm.
• Mechanical loads in the form of shock, for II-IV class: 80, 150, 300 J.

The cylinder mechanism has a secret of varying complexity, depending on the number of combinations created by the pins. The length of the locking pin is the same, unlike code. The number of combinations (N) and complexity is determined by the number of notches n and notches k on the working surface of the key, total: N = n ^k

Kale locks: lineup, key features

Kale locks - worthy representatives of the family of cylinder mechanisms, are in great demand and respect among door manufacturers and many buyers. The lock resource of this company is designed for at least 40 thousand cycles, which greatly increases the service life and minimizes the number of failures.

Maximum protection against hacking: the possibility of transcoding, the presence of an armor plate, the system of blocking pins OBS - when trying to break in (bumping), the mushroom shape of the pins - protection when selecting a code; rods from stainless steel - from drilling.

Kale locks (cylinder mechanism "Series 164"):

• BNE-Z (IV class). For metal doors, 2 mounting keys, maximum protection against burglary. Protection against drilling, bumping, picking, code selection.
• AS (IV class). Alarm, 6 brass pins, the main methods of protection against hacking.
• CEC (IV class). Additional steel insert, OBS protection, code elements in 3 rows, reversible key.
• YGZ (IV class). Steel insert passing through the cylinder body, OBS system, 6 brass combinational pins.
• DB (IV class). 10 combination brass pins, OBS system, additional steel plates. Model DBME (key-turntable) - increased tear resistance.
• OBS B. 10 combination pins made of brass, OBS S - 6 pieces, safety class IV, locking pins operating on the OBS B and OBS S systems, respectively. Models OBS BN and OBS S - cylinder key / key mechanism; Sun and SC key combination with turntable.
• B (II class): 10 combined pins. DBME key / pin break protection, BN key / key, BM key / pin.
• S (II class): 6 combinative pins (91,000 combinations). SX - long stem, SN key / key.
• G (II class): 6 combinational pins (55,000 options) GN - key / key, GM key / spinner.
• F (II class): made to open with a cross-shaped key, 6 brass pins.

Cylinder mechanism Apecs: types, characteristics

Apecs has been the largest distributor of locks and various door hardware on the former USSR market since 1992.

The most popular among buyers are cylinder mechanisms, despite the wide price range, any products offered are of high quality and excellent design.

The company offers two types of cylinder systems:

• Symmetrical.
• Asymmetric.

Brands:

• XS. Pins 18; steel pin pressed into the cylinder body - protection against drilling; steel plate - protection against a gap; two steel clamps of the cylinder body - protection against attempts to pull the core; duplicate only from the original.

In conclusion

Choosing a castle is a task that requires an individual approach in each individual case. The cylinder mechanism for the lock has been popular among buyers for more than a dozen years, and the wide variety allows it to be used both in ordinary interior doors, which serve only as a dividing barrier, and for entrance doors, providing them with the maximum level of protection.
