Abstract

FIELD: mechanical engineering. SUBSTANCE: head is made in the form of a ball segment with odd number of grooves reducing in depth from the bearing end to the tip. One side of the grooves is made straight, and the other one is tapered to provide rotation of the screw or the wood screw only in one direction. EFFECT: improve structure. 3 dwg

Description

Изобретение относится к машиностроению, в частности к резьбовым элементам типа винт и шуруп. The invention relates to mechanical engineering, in particular to threaded elements of the type screw and screw.

Известны головки винтов и шурупов, в которых элементы под ключ выполнены в виде кольцеобразных углублений, образованных двумя фигурными поверхностями: шестигранными, четырехгранными, трехгранными и овальными [1] . Known heads of screws and screws in which the turnkey elements are made in the form of ring-shaped recesses formed by two curly surfaces: hexagonal, tetrahedral, trihedral and oval [1].

Недостаток известных конструкций головок в том, что винты или шурупы можно легко вывинтить монтажным инструментом с лезвием, соответствующим углублению в головке. A disadvantage of the known head designs is that screws or screws can be easily unscrewed with a mounting tool with a blade corresponding to a recess in the head.

Известны также полукруглые головки винтов и шурупов, в которых выполнены шлицы или крестообразное углубление под отвертку [2] . Semicircular heads of screws and screws are also known, in which slots or a cross-shaped recess for a screwdriver are made [2].

Наиболее близкой к изобретению по технической сущности является головка винта или шурупа, содержащая тело вращения с равномерно расположенными на его поверхности уменьшающимися по глубине от основания к вершине канавками, имеющими одну боковую сторону прямую, а другую со скосом [3] . Closest to the invention in technical essence is a screw or screw head containing a rotational body with grooves evenly spaced on its surface, decreasing in depth from the base to the apex, having one straight side and the other with a bevel [3].

Недостатком известного решения является выполнение головки в виде полушара с четным количеством канавок, что позволяет вывинчивать винты и шурупы при захвате головки плоскогубцами за диаметрально противоположные канавки. A disadvantage of the known solution is the execution of the head in the form of a hemisphere with an even number of grooves, which allows you to unscrew the screws and screws when gripping the head with pliers for diametrically opposite grooves.

Целью изобретения является предотвращение неразрешенного отвинчивания. The aim of the invention is to prevent unauthorized unscrewing.

Для достижения указанной цели головку выполняют в виде шарового сегмента с нечетным количеством канавок. To achieve this goal, the head is made in the form of a spherical segment with an odd number of grooves.

На фиг. 1 показан шуруп с головкой в виде шарового сегмента; на фиг. 2 - винт с аналогичной головкой; на фиг. 3 - сечение А-А на фиг. 2. In FIG. 1 shows a screw with a head in the form of a spherical segment; in FIG. 2 - a screw with a similar head; in FIG. 3 is a section AA in FIG. 2.

Головка 1 винта и шурупа имеет форму шарового сегмента и выполнена с нечетным количеством канавок 2. Канавки равномерно расположены на поверхности головки, уменьшаются по глубине от основания к вершине и имеют одну сторону прямую, а другую - со скосом, что позволяет вращать крепежный элемент только в сторону завинчивания. The head 1 of the screw and screw has the shape of a spherical segment and is made with an odd number of grooves 2. The grooves are evenly located on the surface of the head, decrease in depth from the base to the top and have one side straight and the other with a bevel, which allows you to rotate the fastener only in screwing side.

Винт или шуруп закручивают специальным ключом, имеющим внутреннюю выемку по форме головки и выступающие захваты, соответствующие количеству канавок. The screw or screw is tightened with a special wrench having an internal recess in the shape of the head and protruding grips corresponding to the number of grooves.

Такое выполнение головки винта или шурупа предотвратит неразрешенное отвинчивание. (56) 1. Авторское свидетельство СССР N 410176, кл.
