Description

Изобретение относитс к области машиностроени и может быть использовано дл разъемного соединени различных узлов и деталей машин.The invention relates to the field of mechanical engineering and can be used for detachably connecting various components and parts of machines.

Известна шпилька, содержаш,а корпус, подпружиненный толкатель, размеш,ениый в осевом отверстии корпуса, и кулачок с наклонной к оси поверхностью, шарпирно закрепленный в сквозном пазу на конце корпуса 1.Known stud, containing, and the body, a spring-loaded pusher, stir, eny in the axial bore of the body, and a cam with a surface inclined to the axis, sharply fixed in the through groove at the end of the body 1.

Однако известна шпилька не обладает достаточной надежностью, так как осевое отверстие корпуса, в котором размещен толкатель , значительно ослабл ет шпильку в поперечном сечении. Кроме того, известна шпилька недостаточно быстросъемна .However, the known pin is not sufficiently reliable, since the axial bore of the housing in which the pusher is placed significantly weakens the pin in cross section. In addition, the known stud is not fast enough.

Цель изобретени - повышение надежности и быстроты срабатывани .The purpose of the invention is to increase the reliability and speed of operation.

Дл достижени цели кулачок выполнен с фигурным сквозным пазом, а конец толкател - в виде вилки с поперечной осью, проход щей через фигурный паз кулачка .To achieve the goal, the cam is made with a figured through groove, and the end of the pusher is made in the form of a fork with a transverse axis passing through the figured cam groove.

На фиг. 1 изображена шпилька, общий вид; на фиг. 2 - сечение А-А фиг. 1.FIG. 1 shows the stud, general view; in fig. 2 is a section A-A of FIG. one.

Шпилька содержит цилиндрический корпус 1 с осевым отверстием и сквозным пззом 2 на его конце, толкатель 3, один конец которого выполнен в виде вилки 4 с поперечной осью 5, пружину 6 и кулачок 7 с наклонной к оси поверхностью, имеющей фигурный сквозной паз 8. Кулачок шарнирно закреплен в сквозном пазу корпуса на оси 9.The hairpin has a cylindrical body 1 with an axial bore and a through bite 2 at its end, a pusher 3, one end of which is designed as a fork 4 with a transverse axis 5, a spring 6 and a cam 7 with a surface inclined to the axis and having a shaped through groove 8. hinged in the through slot of the housing on the axis 9.

Работает устройство следующим образом .The device works as follows.

Перед установкой шпильки в .отверстие необходимо отт нуть толкатель 3 за ручку 10 от корпуса. При этом поперечна ось 5 вилки толкател будет перемещатьс внутри фигурного сквозного паза 8 кулачкаBefore installing the stud in the hole, it is necessary to pull the pusher 3 by the handle 10 from the housing. When this transverse axis 5 of the fork of the pusher will move inside the figured through groove 8 of the cam

и переместит его вниз, утаплива в прорези . После этого шпилька устанаативаетс в отверстие, и ручка 10 отпускаетс . Далее толкатель под действием пружины 6 перемещаетс в сторону оси 9, а поперечна and move it down in a slot. Thereafter, the pin is set into the hole, and the handle 10 is released. Further, the pusher under the action of the spring 6 moves in the direction of the axis 9, and transverse

ось вилки толкател , воздействующа на кулачок через фигурный сквозной паз. пе-ремещает его в рабочее положение.the axis of the fork of the pusher acting on the cam through the shaped through groove. moves it to its working position.

Claims

In the working position, the pusher 3 under the action of the spring 6 is as close as possible to the axis 9, while the axis 5 of the plug is in the lower part of the figured through groove 8 of the cam 7 and fixes the latter. In this position, part of the cam protrudes beyond the cylindrical surface of the housing. The presence of the transverse axis of the fork placed inside the figured through groove of the cam, as well as their interaction, ensures reliable operation of the stud, excluding its spontaneous falling out. In addition, in the stud, the diameter of the hole in which the pusher is located is actually determined only by the diameter of the spring mounted on the pusher and can be quite small, which makes it possible to reinforce the working section of the stud. 2: 5 jg 15 53 The formula of the invention The hairpin, comprising a housing, a spring-loaded pusher placed in the axial bore of the housing, and a cam with a surface inclined to the axis, hinged in the through groove at the end of the housing, is characterized in that speed, the cam is made with a shaped through groove, and the end of the pusher - in the form of a fork with a transverse axis, the passage of necks through the figured groove of the cam.
