Description

В Примен емом пневматическом инструменте не предусмотрены устройства, предотвраш,ающие его самопроизвольное включение в том случае, если при открытом пусковом кране после временного перерыва возобновл етс  подача воздуха. Это вгз1зывает неожиданное включение инструмента, что часто приводит к несчастным случа м.There are no devices in the pneumatic tool used, preventing its spontaneous activation in the event that the air supply is resumed after the temporary interruption with the open starting valve. This causes the unexpected start of the tool, which often leads to accidents.

В описываемом изобретении возможность такого включени  устранена .In the described invention, the possibility of such inclusion is eliminated.

На чертеже показана схема устройства.The drawing shows a diagram of the device.

Защитный замок выполнен в виде подпружиненного обратного клапана /, перемещающегос  в цилиндрическом корпусе 2. Корпус снабжен с одной стороны боковым отводом 3, по которому сжатый воздух подаетс  к инструменту, а с другой стороны-прорезью, куда входит зуб 4 подпружиненной защелки 5, соединенный т гой или тросом с кольцом ручного привода. Подвод воздуха от сети осуществл етс  по трубопроводу 6.The safety lock is made in the form of a spring-loaded non-return valve / moving in the cylindrical body 2. The body is provided on one side with a side branch 3 through which compressed air is supplied to the tool, and on the other side a slot, which includes the tooth 4 of the spring-loaded latch 5 connected by a goy or a cable with a ring of the manual drive. The air is supplied from the network through pipeline 6.

В рабочем положении клапан 1 всегда открыт под действием сжатого воздуха. В случае внезапного прекращени  подачи клапан под действием прзжины 7 закрываетс . При этом зуб 4 защелки 5 входит в прорезь корпуса, не позвол   клапану открытьс  при возобновлении подачи.In the working position, the valve 1 is always open under the action of compressed air. In the event of a sudden cessation of supply, the valve is closed under the action of the action 7. In this case, the tooth 4 of the latch 5 enters the slot of the housing, preventing the valve from opening when the feed is resumed.

Освобождение клапана и включение инструмента в этом случае может быть произведено только оператором путем принудительного воздействи  на защелку.Releasing the valve and turning on the tool in this case can only be done by the operator by forcing the latch.

Предмет изобретени Subject invention

Защитный замок дл  пневматического инструмента и ему подобны.ч устройств, отличающийс  тем, что, с целью автоматического отключени  инструмента при прекращении подачи сжатого воздуха и предотвращени  самопроизвольного его включени  в момент восстановлени  подачи, он выполнен в виде располол ;енного на входе в инструменг подпружиненного обратного клапана, взаимодействующего с механической защелкой, установленной на корпусе инструмента.A protective lock for pneumatic tools and similar devices, characterized in that, in order to automatically shut off the tool when the compressed air supply is cut off and prevent it from being turned on spontaneously at the time the feed is restored, it is designed as a spring loaded return tool. valve interacting with a mechanical latch mounted on the tool body.
