Description

(54) PLUG FOR MOUTH CAPACITY

I

FIELD OF THE INVENTION The invention relates to machine-building and, in particular, to the fuel tanks of vehicles.

A known closure for a container neck, for example, a vehicle tank, contains a rotatable plug associated with the neck, in the central part of which a locking device l is installed.

A disadvantage of the known gate is the ability of unauthorized persons to unscrew the plug.

The closest technical solution to the invention is a stopper for the throat of a vehicle fuel tank, containing a rotatable plug associated with the throat, installed coaxially with it and covering its lid with an axial bore, a locking element and a locking device with a powered element installed in the axial bore of the lid.

However, such a shutter is not sufficiently reliable due to the fact that the locking device is easily opened, which ultimately makes it possible to unscrew the front panel to unauthorized persons.

The purpose of the invention is to increase the operational reliability of the gate.

To accomplish this goal, the locking device is equipped with an intermediate disk installed between the screw-cap and the outlet, filled with radial grooves in which the sliders are placed | and graduated dials 1and discs located between the lid and intermediate disc, while the graduated discs are fixed on eccentric fingers, opposite ends installed in the lid and sliders, the plug is made with a hollow slope coaxially with the axial opening of the cap installed in the cavity of the specified protrusion of the tube to interact with polyuipmi.

Claims (2)

In addition, as a result, the 1st element can be in the form of a splinterplate, n it is advisable to place the sliders around the circumference of the disk under the angle 12O. Fig, 1 shows the preferred approach, section; in fig. 2 - the same, kind of ssy xy. The closure for the container neck contains a rotary plug 1, which is adjacent to the neck, is installed coaxially with and covering its lid 2 with the axial bore 3, the locking element 4 into the locking device with the flood element 5, installed in the axial bore 3 of the lid 2. The locking device is fitted with an intermediate a disk 6 installed between 1fob 1 and the lid 2 and made with radial grooves 7, in which the sliders 8 are placed, in graduated composing disks 9 located between the lid 2 and the double disk 6, with the graduated Bath discs 9 are mounted on eccentric fingers 10, opposite ends installed in cover 2 and sliders 8. Cork 1 is made with a coaxial axial hole 3 of cover 2 with a hollow protrusion 11, and the driver element 5 is made in the form of a faceted rod 11 installed in the cavity of the cork protrusion 11 1 for interacting with sliders 8 ,. To install the cover in the open-dial position, 9 are placed on a certain division. In this case, the lower end of the carrier element 5 leads the locking element 4 out of the zone of the opening 3 and the faceted rod of the pushing element 5 under the action of the spring 12 moves into the opening 3. Thus, the plug 1 and the cover 2 are rigidly connected to each other. The shutter can be screwed onto the neck of the fuel tank. . To set the shutter to the secret position, it is necessary to manually press the release rod 13, thereby moving the driver element 5 downwards. By turning the dial-up discs 9, the old porous element 4 is moved into the area of the opening 3, restricting the movement of the faceted rod of the carrier element 5 upwards. The cork 1 and the roof 2 are unstuck, as a result of which 134 krpika 2 freely rotates relative to the cork 1. It is impossible to remove it from the fuel tank without knowing the encrypted number. In order to unscrew the bolt, it is necessary to re-set the composing discs 9 into a certain position, in which the locking elements 4 insert the openings 3, and the driver element 5 rigidly connects the stopper 1 with the lid 2. Invention 1. The lock for the container neck, 1fe - property fuel tank of a vehicle, containing a rotatable plug connected to the throat, installed coaxially with it and covering its cover with an axial bore, a locking element and a locking device with a driving element installed in the axial the lid bore, characterized in that, in order to increase its operational reliability, the locking device is removed from the interfacing disk mounted between the stopper in the lid and made with radial grooves in which the sliders are located and graduated composing disks located between the lid and the intermediate disk, at the same time, the graduated disks are fixed on eccentric palms, opposite to the ends installed in the cover and sliders, the cork is made with a hollow protrusion coaxially with the axial opening of the cover, and Ovodkova element is a spring-loaded rod of cut, ustanovlshnogo in the cavity of said stopper protrusion for engagement with the sliders. 2. The closure according to claim 1, of which is that the closure element has the shape of a hexagon. 3. The closure of claim 1, of which is that the sliders are placed around the disk at an angle of 120.
