Description
Technical field
The present invention relates to the mechanical part of oxygen dispenser, be specially the throttle operation device that hand combines automatically.
Background technique
Vehicle-mounted oxygen dispenser is adjusted by the rotating speed of adjustment throttle to motor when oxygenation operates.Operationally, along with the change of working pressure, working load is also along with change for the machine of oxygen dispenser, the rotating speed of motor then changes along with the change of load, maintain the relatively stable of motor, also must adjust the throttle of motor, make rotating speed remain stable.The operation equipment of existing hand throttle uses following two kinds of structures usually; One is rack structure, and least displacement throttle being adjusted at every turn due to the tooth of tooth bar and the interval of tooth can not be less than the interval of tooth, does not have neutral position, can cause the too high or too low of rotating speed between the interval of tooth; Another kind is screw structure, and its reaction velocity is slow, and self-lock force is little, and the vibration that machine produces easily makes throttle drift about.
Improvement for the problems referred to above proposes a kind of Manual accelerator operating device, can adjust arbitrarily the rotating speed of motor as required, and adjustment in time, improves control accuracy.But can vary with each individual in manual adjustment control of engine speed precision, be difficult to remain high-precision adjustment, with this manual operation simultaneously also inconvenience to some extent.
Summary of the invention
For the problems referred to above, the invention provides the throttle operation device that hand combines automatically, artificially can adjust arbitrarily the rotating speed of motor as required, also automatically can adjust the rotating speed of motor, its control mode variation, the precision of control is higher, and reliability is strong.
Its technological scheme is such: it comprises fixed tray and leads wire tray, described wire tray of leading is set in described fixed tray, described wire tray of leading is connected with handle, the described side face leading wire tray has annular groove, throttle silk thread is wound with in described groove, the described end face leading wire tray and described fixed tray surrounds annular cavity, in described cavity, described fixed tray is set with traction aid, wire tray is led described in described traction aid contact, it is characterized in that: described in lead outside wire tray and be connected with clutch, described clutch connects stepper motor, at throttle mouth, flow transducer is installed, described flow transducer is connected with stepper motor by controller.
It is further characterized in that: described traction aid comprises spring, friction pad, and described spring, friction pad, along the axial distribution of described fixed tray, lead wire tray described in described friction pad contact; Described traction aid comprises spring, friction pad, and described spring, friction pad are along the axial distribution of described fixed tray, and described friction pad contacts described fixed tray; Described traction aid is exactly spring; The described fixed tray in outside of described traction aid and described lead wire tray binding site be provided with dust ring; Described spring is wavy spring.
After the present invention adopts said structure, throttle silk thread is driven by swinging handle, thus manually realize controlling the object that throttle reaches adjustment engine speed, or instant traffic transformation becomes electrical pulsing signal to be transferred to stepper motor by flow transducer, stepper motor band dynamic clutch adjustment throttle, thus realize the object of adjustment engine speed automatically.Such design both manually also can adjust engine speed automatically, and diversified control mode improves the precision of control, made equipment reliability strong.
Accompanying drawing explanation
Fig. 1 is sectional view of the present invention.
Embodiment
See Fig. 1, the present invention includes fixed tray 9 and lead wire tray 3, lead wire tray 3 and be set in fixed tray 9, lead outside wire tray 3 and be connected with clutch 1, clutch 1 outer end is connected with stepper motor 2, throttle mouth (not providing in figure) installs flow transducer (not providing in figure), flow transducer is connected with stepper motor 2 by controller (not providing in figure), lead wire tray 3 installation and be connected with handle 5, the side face leading wire tray 3 has annular groove, throttle silk thread 4 is wound with in groove, lead wire tray 3 and surround annular cavity with the end face of fixed tray 9, traction aid is set with at described cavity internal fixation disc 9, traction aid comprises wavy spring 7, friction pad 8, both are along the axial distribution of fixed tray 9, wire tray 3 is led in friction pad 8 contact, also fixed tray 9 can be contacted.Spring 7 also can use as traction aid separately.The outside of traction aid, fixed tray 9 with lead wire tray 3 binding site be provided with dust ring 6.Dust ring 6 can prevent dust and other impurities from entering wavy spring 7 with in the chamber at friction pad 8 place, lead the friction lock that wire tray 3 is produced by traction aid, and locking is reliable, and can operates it at any time.
After the present invention adopts said structure, throttle silk thread 4 is driven by swinging handle 5, thus manually realize controlling the object that throttle reaches adjustment engine speed, or flow transducer will traffic transformation become electrical pulsing signal to be transferred to stepper motor 2 timely, stepper motor band 2 dynamic clutch 1 adjusts throttle, thus realizes the object of adjustment engine speed automatically.Such design both manually also can adjust engine speed automatically, and diversified control mode improves the precision of control, made equipment reliability strong.Throttle silk thread can be wound uniformly and unclamp, and the rotating speed of motor can be adjusted arbitrarily as required; And friction pads can be pressed on and leads in wire tray or the elastic force of spring directly acts on and leads wire tray by the elastic force of spring, the frictional force produced can effectively prevent from leading wire tray non-lever operated time because of the relative movement caused of the external force such as the vibration of machine, the throttle returning spring power of motor, thus the drift of throttle can be prevented.
