Description

A kind of pneumatic control handle

Technical field

The utility model relates to control apparatus, and particularly a kind of pneumatic control handle is mainly used in air-balance control and the Hoist Control Unit.

Background technique

Relate to the pneumatic control handle that adopts in the machinery of pneumatic control at present, major part is used in the robotic device, is used for the single work such as " starting/stop ", " rising/decline ", " clamping/loosen " of control apparatus; Be used in the control, the rising of control apparatus that can only be single or decline, but do not possess equilibrium function; Being used in the equipment of up and down balance system control, is integrated pneumatic power control valve on Joystick, but can only be after having pressed the rising button, again by the balance button, could guarantee that up and down balance system and this kind Joystick can not control heavily loaded workpiece.The utility model has remedied above technical deficiency, has realized that Balance Control is compatible simultaneously with the control of going up and down, and can control heave-load device, makes the operator convenient in use, simple, comfortable, and the control of equipment is more tended to diversification, intellectuality.

Summary of the invention

The purpose of the utility model is to design a kind of pneumatic control handle, and Balance Control is compatible simultaneously with the control of going up and down, and can control heave-load device, makes the operator convenient in use, simple, comfortable.

For achieving the above object, the technological scheme of the utility model is:

A kind of pneumatic control handle, it comprises, gear comprises, fixed cover, the opening of one of which end for supplying accurate relief valve body to insert, the other end is offered a central through bore; Adjustment sleeve, it establishes internal thread, is inserted in fixed cover central through bore one side; Mandrel is arranged in the adjustment sleeve, and with the adjustment sleeve screw-thread fit, the one of which end connects accurate relief valve body; Connecting sleeve, one of which end are sheathed on an end of the fixing sheathed central through bore of gear, and the inwall of this end connecting sleeve is established a limited step, and the connecting sleeve the other end is provided with adpting flange; Adpting flange central authorities offer a through hole; Central shaft, the one of which end is inserted in the connecting sleeve from the adpting flange center through hole, is connected with the gear mandrel; Between central shaft and the connecting sleeve seal ring is set, and spacing by the limited step of the inwall of connecting sleeve; Taper knob is sheathed on and exposes to the outer central shaft of adpting flange.

Further, the central through-hole wall of described adpting flange also is embedded the firmly damping ring of central shaft.

Expose to and establish the control knob that can be replaced with different power source control on the outer central shaft of adpting flange according to demand again.

Described adpting flange exterior edge face is provided with some screws, and at least one has the bolt of position-limiting action to control knob.

In addition, also comprise the Hough assembly that can be fixed on Joystick the relevant position of equipment, this Hough assembly is arranged at the connecting sleeve place.

During operator's rotatable handle, the central shaft in the handle rotates, and the mandrel that drives in the gear rotates, and by the amount of feed of gear decision mandrel, thereby determines the air pressure controlled quentity controlled variable of accurate reduction valve to equipment, the final control that realizes equipment.

Have, the control knob on the Joystick can be realized the control of required function again.

The advantage of the utility model is:

The utility model has remedied the deficiency of existing technology, has realized that Balance Control is compatible simultaneously with the control of going up and down, and can control heave-load device, makes the operator convenient in use, simple, comfortable, and the control of equipment is more tended to diversification, intellectuality.

It comprises: the gear that connects the accurate reduction valve of air-balance control apparatus, links with accurate reduction valve, the central shaft that links with gear, the copper sheathing that is connected central shaft and gear, the firmly damping ring, adpting flange, control knob, taper knob, HALF assembly etc. of central shaft.
