RU2265U1 - LOCKING CASTLE - Google Patents

Abstract

A padlock containing a housing, a cylinder mechanism with a leash, a rotatable-sliding handle, characterized in that the housing is integral, the locking cam is made with a segmented protrusion, the play of which in the groove of the handle is equal to the play of the handle in the housing, and the free end of the handle is deepened to the entire thickness lock cases.

Description

zzhok shshshmi.

The padlock is designed to lock the doors of various rooms and structures

A padlock is known according to the copyright certificate @ 51Sh / 1979 "/ containing a locking mechanism, a handle and a spring-loaded lever locking the two shoulders, mounted on an axis in the slot of the glass, and pinned to the lock case.

The disadvantages of this castle are:

-Corpus complex shape;

-the presence of a lever system that increases the number of parts up to 19 pieces;

-small recess in the body of the free non-lockable end of the handle, not looking for bending of the handle with its subsequent turn and removal of the lock from the ears;

 horizontal position of the axis of the locking mechanism, which makes it possible to get precipitation into the locking mechanism. 1 also known padlock according to copyright certificate

i 9В155 / t960r; / are the closest to this utility model. The lock consists of a body, a rotary-sliding spring-loaded bungee, a secret mechanism with a rotary element in the form of a cylinder and a locking element made in the form of a cylindrical spring-loaded plunger having a reciprocating movement located coaxially to the rotary element provided with a bevel that interacts with the corresponding bevel made in the locking groove of the bow. The disadvantages of this lock are:

- a small depression in the body of the free non-lockable end of the handle, not excluding the bending of the handle or sawing out the upper part of the body with its subsequent turn and removal of the lock from the ears;

 67/04 p -possible inertial fixation of the arch of the osh of a strong side impact; -horizontal arrangement of the axis of the secretion mechanism, allowing atmospheric precipitation to fall into the secret mechanism and stay there a mechanism with a leash, a rotary-retractable bow, the body is made one-piece, the locking cam is made with a segmented protrusion, the play of which in the groove of the handle is equal to the play of the handle in the housing, a free end of the shackle is recessed in the entire thickness of the lock case. In FIG. I shows a cross section of a padlock in a closed position, FIG. a section along A-A of Figure 1, in figure S a section along BB of Figure I, in Fig. 4 is a section of a section along B-B of Figure 2. The padlock / Fig. 1/ consists of a steel casing 1, a handle i fixed to the housing with a locking ring 3, a locking cam 4 whose rotation is limited by a pin 5 / Fig. 8, Fig. 4/ pressed into the housing 1, of the cylinder mechanism 6 / FigL / with a lead 7 protected against drilling by a freely rotating cross washer 8 and a guided protective sleeve 9 sealed in the corset 1. To protect the lock from cross cutting, installation in the housing is possible And m forward ends of the shackle rod 2 freely rotating cylinder, but the mechanism used /fig.Z/ restrained from rotation with two end protrusions, education difference of two diameters in Bipnycet.

The castle works as follows;

In Fig. 1, the lock is locked with a key i To open it, the crest-shaped key opens into the keyhole and turns clockwise / to the right / to the stop of the lower segment of the cam 4 into the pin 5. At this time, the cam 4 presses the shackle 2 with the same free play in and the gap in the groove a / Fig, 2 / and disengages from the groove of the bow S; The handle 2 is unlocked and can be removed from the lock

Locking is done in reverse vice; The handle S is inserted into the housing until it stops by turning the key; the lead 7 of the cylinder mechanism 6 rotates the cam 4, the locking segment of which enters the groove into the pin 5i until it stops; The key is removed, the lock is locked;

Improving the reliability is achieved by the fact that the leash of the cylinder mechanism is constantly in mesh with the cam eliminates the reverse rotation of the cam, that is, unlocking the lock. Manufacturability is achieved by the fact that the body, like the other parts located in it, are made in the form of bodies of revolution and

can be made by traditional machining methods: turning |. milling by drilling, grinding, stamping, rolling.

Improving the performance is achieved by the fact that the shift of the center of gravity of the lock ensures its inclined position in the door ears, which reduces the possibility of atmospheric precipitation in the cylinder mechanism
