Description
ОПОРНАЯ ВТУЛКА ДЛЯ АРМИРОВАНИЯ ОТВЕРСТИЯSUPPORT SLEEVE FOR REINFORCING HOLE
1one
Изобретение относитс к области машиностроени и может быть использовано дл кренлени металлических стержней в неметаллических опорах, например ножек скамеек в кузовах грузовых автомобилей.The invention relates to the field of mechanical engineering and can be used for the heeling of metal rods in non-metallic supports, for example, legs of benches in the bodies of trucks.
Известна опорна втулка дл армировани отверсти , содержаща цилиндрический распорный участок с продольной прорезью и выступами, расположенными по цилиндрической поверхности и отогнутыми в сторону стенок отверсти с возможностью внедрени в них.A known support sleeve for reinforcing an opening comprises a cylindrical expansion section with a longitudinal slit and protrusions arranged along a cylindrical surface and bore toward the walls of the opening with the possibility of being inserted into them.
Однако эта .втулка имеет ненадежную фиксацию в отверстии, так как последн зависит от первоначального отогнутого положени боковых стенок цилиндрического распорного участка и выступов, внедр ющихс в стенки отверсти . С целью устранени этого недостатка и улучшени эксплуатационных свойств в предложенной опорпой втулке выступы выполнены в виде отбортовок вдоль прорези С пилообразной пасечной по их кромкам .However, this sleeve has an unreliable fixation in the hole, since the latter depends on the initial bent position of the side walls of the cylindrical spacer portion and the protrusions embedded in the walls of the hole. In order to eliminate this drawback and improve the operational properties in the proposed sleeve, the protrusions are made in the form of flanging along the slot C of the saw-tooth beacon along their edges.
На чертеже представлена предложенна опорна втулка дл армировани отверсти .The drawing shows the proposed support sleeve for reinforcing the hole.
Втулка состоит из цилиндрического распорного участка 1 с продольной прорезью 2, вдоль которой расположены отбортовки 3 с пилообразной насечкой по их кромкам 4. Поеле установки центрирующего участка 5 в огверстие 6 плиты 7 к торцу втулки прикладываетс осевое усилие Р, которое вгон ет втулку полностью в отверстие, причем зубь пилообразной насечки удерживают ее от выпаДани из указанного отверсти . Затем во втулку вставл ют за-крепл емый металлический стержень 8. Усили , удерживающие втулку в отверстии, практически не завис т от распора ее цилиндрического участка и упругих свойств материала втулки.The sleeve consists of a cylindrical spacer section 1 with a longitudinal slit 2, along which flanges 3 with a saw-tooth notch along their edges 4 are located. , and the tooth of the sawtooth cut keeps it from dropping out of the specified hole. Then, a snap-in metal rod 8 is inserted into the sleeve. The forces holding the sleeve in the hole are almost independent of the expansion of its cylindrical portion and the elastic properties of the sleeve material.
