Abstract

CONTROL ELEMENT, containing: a body with a latch and a release spring coaxially located inside it, a knob, a latch position switch with sockets of different depths, distinguished by the fact that, in order to increase the reliability of fixation and ease of operation, the knob is designed as a lever, hinged mounted in a transverse window of the housing on an axis, perpendicular to the axis of the retainer, outside it and mated with two rollers, coaxially mounted on the retainer on an axis parallel to the axis of rotation of the lever, and placed on the other side of the pins of the latch, the latch position switch is made in the form of a ring with a handle mounted on the neck of the case so that it can rotate around it, and nests of different depths are made on the end of the ring facing the lever and are aligned with this protrusion. .

Description

The invention relates to the field of mechanical engineering, to mechanical systems management, devices for moving elements.

Known control element; consisting of a casing with coaxially arranged inside it:: I have a spindle and a retainer with a sleeve stole as well as a clip, one end of which is pivotally attached to the casing of the handle / and interacting with a roller, fixed to the retainer. Staple Issue: Wave 1-a with the shank in parts, rests under the action of a spring in the handle body L.

The disadvantage of this device is the inconvenience of working with it, since prior to transferring the latch to another polishing / it is necessary to permanently hold it in the retracted position. In addition, with such a design of the lever, it is not possible to increase the latch stroke while maintaining the reliability of its fixation due to the small bevel angle of the clip in contact with the roller. Increasing the bevel angle leads to an increase in the required force on the handle lever and saMeise springs on the spring with less effort “which also reduces the reliability of fixation

A control element is also known, which contains a housing with a latch and a release spring coaxially located inside it, the handle of the position switch FR, the xatora with sockets of different depths 2,

The disadvantage of this device is low fixing reliability due to possible arbitrary shifting of the switch, as well as the inconvenience of operation due to the great effort on the handle.

The purpose of the invention is to improve the reliability of fixation and ease of operation.

The purpose is achieved by the fact that in the control element comprising a housing with a latch and a release spring arranged coaxially inside it, a latch position switch with sockets of different depth, the handle is made in the form of a lever, pivotally mounted in a transverse window of the housing on an axis perpendicular to the latch axis, out of it and matched with two rollers, coaxially mounted1-1 on the retainer on the axis. Parallel to the axis of rotation of the lever, and spaced on the other side from the axis of the retainer S sealing rings to the handle; mounted on the neck of the case with the possibility of rotation around it 5 and the sockets of different depths are located at the end of the ring, facing the protrusion of the lever, and are associated with this prod.

In Fig. 1, it is: it is a control element, a section; in Fig. 2, a section A-A in Fig. 15 in Fig. 3 is a section B-B in Fig. 1,

The control element comprises a housing 1 with a latch 2 coaxially disposed inside it and about an ohm-pr-u: I1noy .3, handle A 5 switches the latching position of the latch 5 s. nests 6 and 7 of different depths. The handle 4 is made in the form of a lever, pivotally mounted in the transverse window 8 of the housing 1. On the axis 9, perpendicular. 10 axis 2 of the latch 2, outside of it and the role conjugated with the “Cvum”; pins 1 1 j coaxially mounted on the latch 2 on the axis 12 of the parallel axis 9 of the rotation of the lever 4 and the distance;

The switch position of the retainer 5 is implemented in the form of a ring 13 with a handle 14, mounted on the neck 15 of the housing 1 with an emolooste

and 7 different depths on the end face 16 of the ring to the 17th lever with this protrusion 17,

The latch 2 is included in the crown 18 of the fixed part 19. On the case 1, the immobilizers 20 of the rotation of the ring 13 and the longitudinal window 21 are mounted for mixing of the ROLLERS 11 and the lever 4.

Control element works in a way that follows.

The uncoupling parts of the | 9 take the arm of the body 1 with the grooves: 5 pressing the lever 4 to the body S lever 4, leaning on the roller blind, 11; forcing them to move along the window 8. carry off the retainer 2, take it out of the hole 18 of the fixed part 19 At the same time, the protrusion 17 of the lever 4 goes out of the socket b of the switch of the position of the retainer 5, then most fingers turn the handle

14 of the position switch of the retainer 5 to the limiter 20 so that the protrusion 17 of the lever 4 falls into the socket 7 of lesser depth. The fixing part 19 is carried out in the same order with the return of the switch 5 to its original position.

Such an implementation of the control element increases the reliability of fixation and ease of operation of the device.
