(Sk) КЛЮЧ дл ДЕТАЛЕЙ ВРАЩЕНИЯ И ГРАНЕНЫХ ДЕТАЛЕЙ(Sk) KEY FOR ROTATION DETAILS AND GRINDED PARTS

II

изобретение относитс к мебельной (легкой) промышленности, а именно к инструментам, примен емым при сборке корпусных изделий мебели винтовыми ст жками,.и может быть использовано в любой отрасли народного хоз йства как инструмент дл передачи детал м вращени и граненым детал м крут щего момента.The invention relates to the furniture (light) industry, namely, to tools used in the assembly of furniture furniture with screw ties, and can be used in any branch of the national economy as a tool for transmitting parts of rotation and faceted parts of torque. .

Известен ключ, предназначенный дл , сообщени детал м вращени крут щего момента, содержащий подпружиненные; шарнирно соединенные между собой рычаги с руко тками, размещенные на рычагах зубчатые губки дл захвата деталей П.A key is known that is intended to communicate the details of the rotation of the torque, comprising spring-loaded ones; pivotally interconnected levers with handles, toothed sponges on the levers to grip parts P.

Недостатком такого ключа вл ете угловое расположение зубчатых губок по отношению к продольной оси руко ток , что вызывает неудобство работы в труднодоступных местах.The disadvantage of such a key is the angular positioning of the jaws with respect to the longitudinal axis of the handles, which causes inconvenience in working in hard to reach places.

Наиболее близким к изобретению вл етс ключ дл деталей вращени и граненых деталей, содержащий основнойClosest to the invention is a key for rotating parts and faceted parts, containing the main

И вспомогательный шарнирно св занные между собой рычаги с руко тками,размещенные на рычагах зубчатые губки дл захвата деталей 2.And the auxiliary pivotally connected levers with handles, jagged jaws placed on the levers for gripping the parts 2.

Недостаток этого ключа заключаетс в том, чтр при увеличении крут щего момента дл удержани деталей вращени и граненых деталей необходимо значительное увеличение нагрузки на руко тки с помощью кисти руки оператора , что значительно затрудн ет работу с ключом, а а св зи с этим снижает производительность.The disadvantage of this key is that, as the torque increases, in order to hold the rotational parts and faceted parts, it is necessary to significantly increase the load on the handles with the operator’s hand, which makes it difficult to work with the key, and this reduces productivity.

Целью изобретени вл етс повышение удобства эксплуатации и производительности .The aim of the invention is to improve the usability and performance.

Claims

The goal is achieved by the fact that the main lever is made in the form of a long and short component particles hinged to the auxiliary lever, the long part is made in the form of a handle, is spring-loaded relative to the auxiliary lever and has a pin installed at the end of the handle perpendicular to its longitudinal axis hinges of levers, the short part has a toothed sponge at one end, and a longitudinal groove at the other end, which interacts with the handle pin. The drawing shows a key, a general view. The key for rotating parts and faceted parts contains primary 1 and auxiliary 2 levers with handles connected to each other by means of hinges 3 and 4 toothed jaws 5 and b to grip the parts. The main lever 1 is made up of long and short component parts hinged to the auxiliary lever 2, the long part by means of the spring 7 interacts with the handle of the auxiliary lever 2 and has a pin 8 installed at the end of the handle perpendicular to its longitudinal axis. hinges 3 and levers 1 and 2, the short part is made at one end with a toothed sponge 5 at the other — with a longitudinal groove 9 interacting with the pin B of the handle of the main lever 1. The key works as follows. Putting the wrench on the screw head or nut of the threaded joint, which needs to be informed of the torque, levers 1 and 2 are adjusted with the help of handles until the jaws 5 and 6 are in contact with the part head. Then, turning the key, transfer the torque to the head of the part. With an increase in torque and an increase in resistance during screwing up, it is not necessary to compress the handles of levers 1 and 2 (which would have an effect on increasing the loads of the operator's hand); it is enough to apply the load on the handle of the main lever 1, since the system of the lever and the release of the hinge of the key allows at the same time to increase the gripping force of the head of the part. The use of a key of this design allows to increase the gripping force of the screw head. Claims Key for rotating parts and faceted parts comprising main and auxiliary pivotally connected levers with handles, toothed jaws on the levers for gripping parts, characterized in that, in order to improve ease of operation and increase productivity, the main lever is made in the form of a long and short component parts hinged with an auxiliary lever; the long part is designed as a handle, is spring-loaded relative to the auxiliary lever and has A pin located between the hinges perpendicular to its longitudinal axis perpendicular to its longitudinal axis (shchagi, the short part has a notched lip at one end, and a longitudinal groove at the other end, which interacts with the hinge pin.
