EA000331B1 - Cable lock and seal device - Google Patents

Abstract

1. Cable lock and seal device comprising a cylindrical casing, steel cable and locking needle, characterized in that said casing consists of two hollow cylinders, having a bottom, wherein one cylinder is inserted into the other, thus forming inside a closed cylindrical cavity with two transverse apertures and an aperture in the bottom of the inner cylinder, said aperture is slightly shifted along the axis perpendicular to the axis of the transverse apertures. 2. Device according to Claim 1, characterized in that on the wall of the inner cylinder a cut-in is made along the axis, perpendicular to the axis of said transverse apertures, said cut-in forms a cavity between the walls of the cylinders, where R-shaped laminated spring is placed, lockingly acting upon annular grooves of said locking needle, jamming the cords of said cable, inserted into the transverse apertures of the casing. 3. Device according to Claim 1 or 2, characterized in that the casing of said locking needle is equally shifted towards the aperture in the bottom of the inner cylinder, and the opposite end has a tapered cone and, being on the level of the bottom of the inner cylinder is enclosed with a plastic element.

Description

Locking and sealing device refers to locking devices for single use mainly of guarded objects and premises.

Various locking and sealing devices are known (Report on patent studies of a locking device for vans, containers, railway cars and disposable tanks. Yoshkar-Ola. 1996), containing either rigid metal rods or flexible metal ropes clamped in the body by means of collets, locking rings and other elements.

The closest solution is a device containing a hollow cylindrical body with transverse holes through which the branches of the steel rope are passed, as well as a cylindrical metal retainer, the axis of which is somewhat offset.

A disadvantage of the design of the known device is that with operational reliability it does not completely eliminate the falsification of the device by substituting a falsified element before using the locking lock.

The objective of the invention is to eliminate the possibility of extracting from the device any of the elements without mechanical destruction of the device as a whole before and after its use.

The inventive locking and sealing device comprises a hollow body with a closed inner space, formed by two bottom cylinders, and one cylinder is placed in the cavity of the other and has a hole in the bottom slightly offset from the central axis, and perpendicular to the axis of the holes made on the cylindrical surface of the body through which missed branches of a steel rope, pinched by a locking needle, which is made of annular grooves, which has a locking effect located in a special cavity between the cylinder walls, while the working body of the locking needle is somewhat offset along the axis of the displaced hole in the housing, and the opposite end of the needle has an axial cone, which, when using a locking and sealing device, is fixed at the bottom of the inner cylinder of the housing with a plastic carrier material .

Comparative analysis with the prototype shows that the use of several additional locking mutually insuring elements represents significant differences from the known device, and in relation to other known devices, the claimed locking and sealing device has novelty.

The locking and sealing device is shown in:

FIG. 1 - before use; figure 2 - after use. The locking and sealing device comprises a cylindrical body formed by a cylinder 1, inside of which a cylinder 2 is placed, having a hole offset along the axis at the bottom through which a locking needle 3 is placed in the body cavity, which, in turn, is fixed inside the housing by a L-shaped plate spring 4, acting on its annular grooves, and a plastic element and fixing the branches of the steel rope 6 and 7 passing through the holes of the housing.

The device operates as follows. Before using the locking and sealing device, as shown in figure 1, the locking needle 3 pinches only the branch of the rope 6, while the L-shaped spring 4 already eliminates the removal of the locking needle 3 from the housing. When the axial external action of the locking needle 3 is slightly offset from the axis of the cone has a squeezing squeezing effect on the branch 7 and flows around the external impact of the plastic element 5.

Claims (3)

CLAIM 1. A locking and sealing device containing a cylindrical body, a steel cable and a locking needle, characterized in that the body consists of two hollow cylinders having a bottom, one cylinder being placed in the cavity of the other, thereby forming a closed cylindrical space with two transverse holes inside and a hole in the bottom of the inner cylinder slightly offset along the axis perpendicular to the axis of the transverse holes. 2. Locking and sealing device for π. 1, characterized in that on the wall of the inner cylinder along the axis perpendicular to the axis of the transverse holes, a cut is made forming a cavity between the walls of the cylinders, where the L-shaped plate spring is placed, which acts on the annular grooves of the locking needle, which clamp the branches of the steel cable, transverse housing bores. 3.
