Blocking device

Description:

The invention refers! to locking devices designed to prevent unauthorized access to the assembly parts of the pipes, in particular to the valves mounted on the gas supply pipes.

The device for preventing the unsanctioned access that is known is known! from a mounting box! over laces or other locks, ensuring their protection [1].

The closest solution! represent! an anti-crime seal, which consists! from a table body! plastic! in form! box with cavity and ribs inside it [2].

These near solubles present! An important disadvantage: preventive installation! of devices on the surface! of the protected object, о operation is not always possible !, and the protected object waves! s! be placed on the surface о! plan!.

The problem I solve! The present invention is the development of a simple device, easily applicable and protected, which does not require! о mount a quote! on the surface of the protected objects and that would ensure the protection of the objects with rectilinear surfaces, especially of the valves of the gas supply pipes.

The locking device, according to the invention, solved! problem mentioned! by that c! includes a hollow body, provided with a lacquer. The body is executed in two! coupled pieces, each one of which is executed! in form! open box! from the side of the coupling surface, at the same time, on two opposite walls of each! king the parts are executed semicircular projections, which form! when coupling a hollow cylinder. On one of the other two opposite walls of the body is fixed a lacquer, and on the other - a pair of coupled ears. On the basis of each part, longitudinal slits are symmetrically executed, the axes of which are perpendicular to the axes of the semi-cylindrical projections. The lacquer confines projections executed on each of the coupled parts of the body, one - with ratchet and orifice, the axis of which is perpendicular! of the ratchet, another with t! ietur !.

The result of the proposed invention is const! in the simplicity of applying the protective device to the protected object, for its protection and verification.

The invention is represented! in the figures below:

FIG. 1, body 1, top view;

FIG. 2, body 1, side view !;

FIG. 3, body 1, view 4;

FIG. 4, body 2, top view;

FIG. 5, body 2, side view !;

FIG. 6, body 2, view A.

The locking device consists! from a table hollow body! plastic !, provided with a lacquer! The body is executed in two! The coupled sections 1 and 2 provided with the corresponding ribs 3, 4, 5 and 6, internally, parts 1 and 2, are provided with semicircular projections 7, 8, 9 and 10, correspondingly! tor, in lateral perforations, and with longitudinal grooves 11 and 12 in frontal perforations, with closing elements, one in shape! of lamella! 13 with ratchet 14, and another in shape! by proeminenf! 15 with slot! 16, and with the projections 17 and 18 for the installation of the seal.

The locking device works! in the unnatural way.

In order to install the locking device on the protection object, part 1 joins with part 2 through the interaction of the blade 13 with the pawl 14 and the slot 16 of the protrusion 15, which, following the block, forms! a body cav. The body formed by combining parts 1 and 2 applies! above the tap (not shown), so the tap s! place in the cavity formed !, and the bean of the pipe on which the valve is installed! place in the semicircular projections 7, 8, 9 and 10 of the lateral edges. In case the tap is on! In the closed position, the tap handle is inserted in the slots 11 and 12 of the front shelf, after! which, parts 1 and 2 are close to each other! on the overlap of the projections 17 and 18 for the seal application (not shown). In this case, the tap handle goes out! out of the box formed! through slots 11 and 12, indicating its closed position. In case of application of the locking device, when the valve is located! in the open position the handle of the valve sits! in the body cavity.

Damage to blade 13 or protrusion 15, as well as seal, indie! unauthorized access. The presence or absence of the tap handle in slots 11 and 12 of the indie body! closed or open position of the valve, when checking it.

Presents the ribs 3, 4, 5 and 6 in the cavity of parts 1 and 2 they assure! stiffness.
