Изобретение относитс к области машиностроени и может примен тьс дл надежного стопорени резьбовых.элементов как в сквозных , так и в глухих резьбовых отверсти х.,The invention relates to the field of mechanical engineering and can be used for securely locking threaded elements in both through and blind threaded holes.

Известно устройство, содержащее унругую лепестковую пластину, установленную с возможностью ее осевого перемещени и контакта с резьбовым элементом, расположенным в соедин емой детали, накладку прижимающую лепестки к торцу резьбового элемента и жестко скрепленную с ним, при этом на поверхности отверстви соедин емой детали выполнены продольные пазы дл размещени концов лепестков пластины 1 .A device is known that contains a uniform lobe plate installed with the possibility of its axial movement and contact with a threaded element located in the part being joined, an overlay pressing the petals to the end of the threaded element and rigidly fastened to it, with longitudinal grooves on the surface of the hole of the part being joined for placing the ends of the petals of the plate 1.

Недостатком устройства вл етс мала надежность .The disadvantage of the device is low reliability.

Целью изобретени вл етс повыщение надежности .The aim of the invention is to increase reliability.

Цель достигаетс тем, что стопорное устройство , содержащее упругую лепестковую пластину , установленную с возможностью ее осевого перемещени и контак1 1 с резьбовым элементом, расположенным в отверстии соедин емой детели, накладку, прижимающуюThe goal is achieved by the fact that the locking device containing an elastic flap plate, installed with the possibility of its axial movement and a contact 1 1 with a threaded element located in the hole of the connected part, an overlay clamping

лепестки Ш1астиш 1 к торцу резьбового элемента и жестко скрепленную с ним, в накладке выполнены сквозные радиальные пазы дл лепестков пластины, а в резьбовом элементе осевого ютверстие дл 1 управлени радиальными перемещени ми лепестков пластины.the petals of the Shashastish 1 to the end of the threaded element and rigidly attached to it, the lining has through radial grooves for the petals of the plate, and the threaded element has an axial yuthole for 1 controlling the radial movements of the petals of the plate.

На фиг, 1 изображен продольный разрез устройства после монтажа ; на фиг, 2 - то же, при : монтаже и демонтаже;; на фиг, 3 - се10 чение А-А на фиг. 1Fig, 1 shows a longitudinal section of the device after installation; FIG. 2 is the same with: mounting and dismounting ;; FIG. 3 is section A-A in FIG. one

Стопорное устройство содержит упругую лепестковую пластину 1 с концами 2, установленную с возможностью ее осевого перемещени и контакта ррезьбовым элементом 3, The locking device contains an elastic flap plate 1 with ends 2 installed with the possibility of its axial movement and contact with a threaded element 3,

15 расположенным в соедин емой детали 4, накладку 5 с отверстием 6, прижимающую лепестки пластины 1 к торцу 7 резьбового элемента 3 и жестко скрепленную с ним, при этом на поверхности отверсти : соедии емой детали 4 15 located in the part 4 to be joined, lining 5 with a hole 6, pressing the petals of the plate 1 to the end 7 of the threaded element 3 and rigidly attached to it, while on the surface of the hole: connecting part 4

Claims

20, longitudinal grooves 8 are made to accommodate the ends 2 of the petals of the plate 1, in the pad 5 there are through radial grooves 9 for the petals of the plate 1, and in the threaded element 3 an axial 38 hole 101 to control the radial movements of the petals of the plate 1, the controls can be for example, the rod 11 with a pointed end located in the hole 10,, and the end of the screwdriver 12 installed in the slot 13 of the threaded element 3 ... Installation of the device is carried out as follows. The end screwdrivers 12 are installed in the slots 13. At the same time, the rod 11 is moved and the elastic deformation of the petal plate 1, the ends 2 of which take up the position in the slots 9, does not protrude beyond the inner diameter of the threaded element 3. The screwing of the threaded element 3 is held to the desired depth. After screwing in, the screwdriver 12 is removed, and the lobe plate 1 under the action of elastic forces returns to its original position, the ends 2 of which are located in the longitudinal groove 8 of the part 4 to be joined, thus ensuring reliable locking of the threaded element 3. The device is removed in reverse order. The invention makes it possible to increase the reliability of the threaded connection axes with the convenience of fitting and dismounting in parts with a blind threaded hole. Claims of the stop device comprising an elastic flap plate mounted for axial movement and contact with the threaded element located in the hole t of the part to be joined , an overlay, pressing the plate's petals to the end of the threaded element and rigidly fastened to it, characterized in that, in order to improve reliability, the underlay is made nye radial grooves for petal plates, and. the threaded element is an axial bore for controlling the movement of the plates.
