Disclosure of Invention
The utility model aims at providing a have the mistake to touch or the maloperation and the accident is opened and is leaded to hindering the people, hindering the problem of equipment in order to solve hand-held type pneumatic tool, provide a hand-held type pneumatic control device with safety interlock.
The utility model has the following concrete scheme: the utility model provides a hand-held type pneumatic control device with safety interlocking, includes the mounting bracket, mounting bracket one end is equipped with the handle that stretches out to both sides, be equipped with a mounting panel in the middle of the mounting bracket, the upper surface of mounting panel is equipped with a control air valve A, a control air valve B is equipped with to the lower surface of mounting panel, control air valve A's gas outlet passes through the pipe connection with control air valve B's air inlet, compressed air source is connected to control air valve A's air inlet, pneumatic actuating mechanism is connected to control air valve B's gas outlet, control air valve A one side is equipped with switch on A, control air valve B is located the opposite side and is equipped with switch on B, lie in control air valve A and control air valve B both sides on the mounting panel and respectively be equipped with a brake valve handle, operation brake valve handle is used for opening or closing switch on switch A switches on B.
Control handle is located the inner of mounting bracket and is articulated with the mounting panel, and the control handle outer end is equipped with and is used for handheld holding rod, and the operation holding rod makes control handle be used for opening corresponding switch-on to the inboard rotation of mounting bracket.
Switch on switch A and switch on switch B department respectively are equipped with an elasticity protection mechanism, elasticity protection mechanism includes the spring board, and the spring board is in crimping state and one end and control pneumatic valve A control pneumatic valve B fixed connection, and the spring board other end is located switch on switch A/switch on switch B top and is equipped with the link, the link outer end with the brake valve lever contact.
The leading wheel is equipped with to the link outer end, brake valve lever's the inner and the leading wheel contact.
The working principle of the utility model is as follows: when the pneumatic actuating mechanism needs to be started, two control handles must be held by two hands at the same time, the inner ends of the two control handles simultaneously press the conducting switch A and the conducting switch B to enable the control air valve A and the control air valve B to be in an opening state at the same time, and at the moment, compressed air can pass through the control air valve A and the control air valve B in sequence and finally reaches the actuating mechanism; if only one of the control handles is operated by mistake or touched by mistake, compressed air can be blocked in the control air valve A or B and cannot reach the executing mechanism, if the executing mechanism is stopped, only one hand or two hands are loosened, the spring protection mechanism automatically resets the control handles, and therefore compressed air flowing to the executing mechanism is blocked, and stopping is achieved.
Compared with the prior art, the utility model has the following advantages: compact structure, simple, the simple operation, low in manufacturing cost can stop the operator because the potential safety hazard that the misoperation or maloperation brought when operating pneumatic equipment effectively improves pneumatic equipment's security, has fine spreading value.
