Изобретение отнсюитс к машинострое нию и может быть использовано во всех област х народного хоз йства.The invention is related to machine building and can be used in all areas of the national economy.

Известно запорное устройство дл соединени панелей с односторонним досту пом, включающее винт, втулку, с упорной головкой, телескопически взаимодействуй щую с ней гайку с радиальными лапками, обеспечивающими ее движение в пазах втулки в осевом направлении. Упорна головка втулки снабжена выступами, предотвращающими поворот втулки при монтаже устройства.A locking device for connecting panels with a one-way access is known, including a screw, a sleeve, with a stop head, a telescopically interacting nut with it with radial legs that allow it to move in the slots of the sleeve in the axial direction. The thrust head of the sleeve is provided with protrusions that prevent the sleeve from turning when mounting the device.

С целью упрощени монтажа и повььшени надежности соединени , предлагаемое устройство снабжено пластинчатой С-образной пружиной, закрепленной в цеигре у торца резьбовой части винта, концы пружины охватывают фигурную поверхность втулки и снабжены усиками, вход щими в пазы, сообщающиес с oiw верстием в несущей панели. Упорна головка втулки выполнена с пазом под инструмент , а на опорной поверхности ра-,In order to simplify installation and increase the reliability of the connection, the proposed device is equipped with a C-shaped plate spring fixed in a center at the end of the threaded part of the screw; The thrust head of the sleeve is made with a groove for the tool, and on the bearing surface is

диальных лапок гайки выполнены скосы, взаик1одейетвующие с опорной панелью.The dial pads of the nut are made with bevels that engage the support panel.

Такое конструктивное решение упрощает монтаж и демонтаж за счет сборки и зат жки запорного устройства на несущей панели с последующим соединением с опорной панелью посредством поворота устройства на 90, предотвращает поворот устройства и надежно фиксирует его от самоотвинчивани .Such a constructive solution simplifies installation and disassembly by assembling and tightening the locking device on the carrier panel, then connecting it to the support panel by rotating the device 90, prevents the device from rotating and reliably secures it from self-unscrewing.

На фиг. 1 изображено запорное уст- ройство, закрепленное на несущей панели в положении открыто ; на фиг. 2 - то же, в положении закрыто ; нафиг. 3разрез А-А фиг. 1; на фиг. 4 - запорьное устройство в аксонометрической проекции .FIG. 1 shows a locking device mounted on the carrier panel in the open position; in fig. 2 - the same, in the closed position; see 3A-A, FIG. one; in fig. 4 - locking device in axonometric projection.

Claims

The locking device includes a sleeve 1 with a stop head 2, a nut 3 with radial legs 4, telescopically interacting with sleeve 1, n a screw 5. The device is equipped with a layer 11 G1a1hey C-shaped spring 6 fixed with its center in the annular recess 7 of the screw 5. Ends 8 spring 6 covers, for example, the tetrahedral surface of sleeve 1, and is provided with tendrils 9 entering slots 10, communicating with a hole in the carrier panel 11. The stop head 2 is threaded with a groove 12, for example, a rectangular shape under the tool. On the supporting surfaces 13 of the radial tabs 4, the bevels 14 are made interacting with the supporting body 15. A seal 16 is installed between the panels 11 and 15. The locking device works as follows. The sleeve 1 is inserted into the hole of the carrier. Panel 11, then the nut 3 and the spring 6 are mounted on the sleeve. The screw 5 is screwed through the hole in the sleeve 1. Screwed into the nut 3 and introduced into the groove in the center of the spring 6 by an annular recess 7. The rotation of the locking device of the antenna 9 is inserted into the grooves 10. At the same time, screw 5: adjusts the amount of force aat lc: and. A locking device mounted on the carrier panel 11 is inserted into a rectangular groove made in the support panel 15 along it for and is rotated by turning the device 9O into the help of the tool inserted into the. groove 3.

2. In this case, the ends 8 of the spring 6 12 5 f1 -Z 72 04 are unfolded by the ribs of the sleeve 1 and compressed again, making a click indicating that the position is closed. The spring 6, being constantly in a tense state, prevents the device from self-locking. The connection is tightened by screw 5. To open the locking device, the sleeve 1 is rotated counterclockwise by 90 °, and there is a click indicating that the position is open. Formula, Shadow A locking device for connecting one-way access panels containing a sleeve with a stop head and a shaped side surface, telescopically interacting with the sleeve with a nut with a radial head and a screw, characterized in that, in order to simplify installation and increase the connection reliability, it is equipped with a C-shaped plate spring fixed in the center at the end of the screw thread, with cutouts at the ends covering the figured side surface of the sleeve, the spring being supplied with antennae, the entrance them into slots which are provided at openings in the surface of the panel under the thrust head of the sleeve, which is made with grooves turnkey on the end face.
