(54) УСТРОЙСТВО ДЛЯ ФИКСАЦИИ(54) DEVICE FOR FIXING

Изобретение относитс к области радиотехники, в частности к средствам дл фиксации блоков радиоэлектронной аппаратуры в стойке.This invention relates to the field of radio engineering, in particular, to means for fixing blocks of radioelectronic equipment in a rack.

Известно устройство дл выдвижени и фиксации блоков радиоэлектронной аппаратуры, содержащее кронштейн с упором, жестко закрепленный на задней стенке блока и шарнирно соединенный с подвижной опорой, размещенной в направл ющем пазу стойки, снабженном жестко закрепленным в нем плоской пружиной. При этом на подвижной опоре выполнен выступ с возможностью взаимодействи с упором кронштейна l.A device for extending and fixing blocks of radioelectronic equipment is known, comprising a bracket with a stop fixed on the rear wall of the block and pivotally connected to a movable support placed in a guide groove of a rack equipped with a flat spring fixed in it. At the same time, a protrusion is made on the movable support with the possibility of interaction with the support arm l.

Известное устройство характеризуетс достаточно сложной конструкцией.The known device is characterized by a rather complicated construction.

Известно также устройство дл фиксации , которое может быть использовано , в частности, дл фиксации поворотных блоков радиоэлектронной аппаратуры , содержащее фиксирующую пару, выполненную в виде закрепл емой на стойке плоской пружины с возможностью взаимодействи ее клиновидного кольца с пазом клиновидного профил , выполненным в корпусе блока 12,It is also known a fixation device, which can be used, in particular, for fixing rotary units of electronic equipment, comprising a fixing pair, made in the form of a flat spring fixed on a stand with the possibility of its wedge-shaped ring interacting with a groove of a wedge-shaped profile made in the case of block 12 ,

Облада простой конструкцией, данное устройство в то же недостаточно надежно в работе, так. как не обеспечивает фиксацию блока в направлении, параллельном его оси поворота.Possessing a simple design, this device is not reliable enough in operation, either. it does not ensure fixation of the block in the direction parallel to its axis of rotation.

Цель изобретени - повыиение надежности работы устройства.The purpose of the invention is to increase the reliability of the device.

Поставленна цель достигаетс The goal is achieved

10 тем, что в устройстве дл фиксации, преимущественно поворотных блоков радиоэлектронной аппаратуры, содержащем две фиксируннцие пары, кажда из которых выполнена в виде закреп15 л емой на стойке плоской пружины.с возможностью взаимодействи ее клиновидного конца с пазом клиновидного профил , выполненным в корпусе блока, пазы клиновидного профил 10 by the fact that, in a device for fixing, predominantly rotating units of electronic equipment, containing two pairs of fixings, each of which is made in the form of a flat spring fixed to the stand with the possibility of its wedge-shaped end interacting with the groove of the wedge-shaped profile made in the block body, grooves wedge-shaped profile

20 обращены вершинами навстречу друг другу и размещены-в плоскости, перпендикул рной клиновидному концу плоской пружины.20 face each other vertically and are positioned in a plane perpendicular to the wedge-shaped end of the flat spring.

Claims

In the rack 1 radio-electronic equipment on the axis 2 is installed a rotary unit 3 with us 4 firmly fixed on its upper end face 4, wedge-shaped grooves 5 of which are wedge-shaped ends b of flat pipes 7 fixed on the rack 1. Springs 4 and 7 are installed perpendicular each other, and the springs 4 are fixed on the side 3 in such a way that the tops 8 of their wedge-shaped grooves 5 are facing towards each other, and the springs 4 themselves are somewhat bent (in the working position) down. To fix the block 3 in the working position, push the knobs 9 of the springs 4 and turn the block until the ends 6 of the spring 7 are above the notch 5 of the springs 4, then release the knobs 9, resulting in the ends of the b springs 7 interacting with the slots 5 of the springs 4, the block is unlocked in reverse order. The proposed device makes it possible to compensate for the forces acting on the block as a result of vibrations arising, for example, during transportation of the product. In this case, the forces directed along the axis of rotation of the block are compensated for by the elastic properties of the springs 7, and the forces directed perpendicular to the axis of rotation of the block are compensated for by the elastic properties of the springs 4. The device can be used, in particular, for fixing the rotary blocks of television sets. receivers. Claim device A device for fixation, mainly of rotating electronic equipment, contains two pairs of fixings, each of which is made in the form of a flat spring fixed to the stand with the possibility of its wedge-shaped end interacting with the groove of the wedge-shaped profile made in the body of the block, which differs from In order to increase the reliability of operation, the grooves of the wedge-shaped profile are turned to the opposite ends of the other and are placed in a plane perpendicular to the wedge-shaped end of the flat spring.
