SU805435A1 - Locking device for push-button change-over switch - Google Patents

Description

the buttons are code-coded, for example, numerical designations, and the case is provided with an installation mark.

If it is necessary to fix and lock the buttons in the pressed (drowning) position by turning the flange on the cylindrical part and / yi button in the closed position, the grooves on the button should be made different from each other at the same distance not exceeding the height of the compressed spring.

In addition, for the convenience of assembling the push-button set-top box, a through-hole is made at the radial protrusion of the cylindrical dehal Mo: f "5T bushing, through which the radial protrusions are attached to the cylindrical part. .

FIG. 1 shows the locking device in the closed position with a part of a low cut, general view; in fig. 2 - the same, in the open (on) position, cut.

The locking device includes a housing 1 with a button 2 with a pusher 3 and a return spring 4 located in it. The housing has a guide hole 5 and fastening elements such as a flange 6 and 7 with a nut 8. The inner side surface of the housing 1 is provided with a radial protrusion 9 and a guide To the element is an annular yiiopoM 10. On the side surface of the button 2 there is an annular groove 11, a longitudinal groove 12, an additional 1a annular groove 13, a longitudinal groove 14 and an annular groove 15. The longitudinal grooves 12 and 14 form a single longitudinal groove. A cylindrical part 6 with an outer flange 17 and an inner annular stop 18, provided with a radial protrusion 19, interacts with the annular abutment 0 of the housing 1, is placed between the body 1 and the button 2 concentrically with the possibility of rotation. The end 20 of the protrusion 19 interacts with the annular grooves 11, 15 and with a longitudinal groove 2 of the cap 2. Ring grooves 13, 1 and: groove 14 of the button 2 interact with the radial protrusion 9 of the housing 1.

On the outer surface of the button 2 and flange 17 iiaHeCviiw, respectively, the code marks 21 and 22 in the form of numbers or letters, and on the flange 6 - a reference mark 23, on which the panel 24 is marked to align the code marks when dialing the code to unlock the button 2. B In another embodiment, numerals or letters may be applied on the panels and on button 2 and the flange. 17 - installation labels. The pusher 3 can be made in the form of a bolt with a nut 25.

For ease of assembly, the housing 26 has an opening 26 through which it is fastened.

on the cylindrical part 16, a radial protrusion 19 of a pin, as shown in FIG. 1 and 2, is a one-piece rod. Button 2 (in its lower part) has an additional groove 27. 5 In the initial position, button 2 cannot be drowned, since the radial protrusion 9 of the housing 1 and the end 20 are located respectively in the annular grooves 13 and 11 of the button 2. To unlock the described device,

(O tl. For security) Opportunities for longitudinal movement of the button 2 with the pusher 3, the flange 17 of the cylindrical part 16 and the button 2 are rotated to align the necessary code marks 21 and 22 with the mouth of the 5 mark 23 or with the label on the panel 24: radial protrusion 9, peremshda camping on. the annular groove 13 is aligned with the longitudinal groove 14, and the end 20, moving along the annular groove I, with the longitudinal groove 12. Thereby the possibility of reciprocating longitudinal movement of the button 2 and passing through pusher 3 influences the control organ of the device, switching on the electronic equipment. In case of need fixing and locking the buttons 2 in the recessed position (after it also t) the flange 17 and the knc-ku 2 must be turned through a certain angle. In this case, Xzzah 20 of the protrusion 19 will enter the annular groove 15, and the radial protrusion 9 of housing I will enter the annular groove 11, and button 2 will be locked in the depressed position. To return button 2 to its original position, you need to dial a code number or a code set of letters.

The proposed button set-top box can be used to protect controls., .Q electronic equipment, such as radio or TV buttons, home appliances, and protect control buttons and start buttons of various industrial units and vehicles from unauthorized use by outsiders

by individuals.
