Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Multi-purpose flexible photoconduction string guide, is made up of string target seeker 1, winding pulley group, photoconduction control circuit and operating grip 6.
String seeker 1 is L-type transparent organic glass polyhedron, have the U-type groove 16 of 90 degree of circular arcs from top, L-type polyhedral inner side to inner lower edge, U-type groove 16 becomes vertical direction after making the U-type groove 16 of string from horizontal direction along 90 degree of circular arcs in string seeker 1 bending and draws.
Pulley blocks is made up of six pulleys be arranged on stake body 18 and the driving wheel 5 be fixed on operating grip 6 respectively; Six pulleys on stake body 18 be respectively be positioned at top two two-wheel coaxial wheels arranged side by side 3 and be positioned at two bottom pulley 17 of transferring; In the direction of the axle of two-wheel coaxial wheels 3 and string target seeker 1, the string of string moves towards perpendicular; Two-wheel coaxial wheels 3 with rectangle guide roller frame 11 regularly framework together, rectangle guide roller frame 11 is hinged by movable axis 13 and stake body 18 near string seeker 1 one end, and the other end is connected with stake body 18 with spring trip bolt 15 by spring 14; The trailing wheel of two-wheel coaxial wheels 3 is engaged wheel 12, and engaged wheel 12 is wound around mutually by the driving wheel 5 on wiring and operating grip 6, and being formed can the driven pulley group of rotating in same direction; Flexible metal bellows 4 two ends are separately fixed on stake body 18 and operating grip 6, are responsible for supporting and connection bracket body 18 and operating grip 6, and provide passage for the wiring of connection driving wheel and engaged wheel 12; The front-wheel of two two-wheel coaxial wheels 3 is upper belt pulley 2, two bottom pulley 17 and two upper belt pulleys 2 tangent in same plane, two bottom pulley 17 are fixed on stake body 18, engaged wheel 12 drives upper belt pulley 2 to rotate, and makes string movable between upper belt pulley 2 and bottom pulley 17; Make U-type groove 16 end and upper belt pulley 2 and bottom pulley 17 point of contact on same linear position, and string target seeker 1 is fixed on stake body 18, thus string can be movable in U-type groove 16 under the drive of belt pulley.
Photoconduction control circuit by LED light emitting diode 7, button cell group 9 and micro slide switch 8 in series; Wherein LED light emitting diode 7 buries and is fixed on side, string target seeker 1 bottom, and button cell group 9 and micro slide switch 8 are fixed in stake body 18 front side end, and LED light emitting diode 7, button cell group 9 are all connected by wire with micro slide switch 8; Micro slide switch 8 is fixed on the closedown that control LED light emitting diode 7 is convenient on 18 surfaces on stake body.
The using method of Multi-purpose flexible photoconduction string guide is as follows:
The installation of string: will be pressed in U-type groove 16 for drawing string 10 front end, and mentioning two groups of two-wheel coaxial wheels 3, being clipped in by string between upper belt pulley 2 and bottom pulley 17, string rear section rides in the U-shaped locating slot 19 on stake body 18 both can.
Lighting operation: first being closed by micro slide switch 8 when for drawing string, powering on to photoconduction control circuit, makes LED light emitting diode 7 light, and provides string target seeker 1 photoconduction to draw work.When drawing after string terminates, opening micro slide switch 8, making the power-off of photoconduction control circuit.
Method of operating: complete for after drawing fixing on string guide of string 10 according to the installation method of above-mentioned string, open photoconduction control circuit according to bright method of operating simultaneously, hand-held operation handle 6, string guide leading head entirety is changed string mouth bottom Zheng audio amplifier send in audio amplifier for drawing near the lower position of string hole, at this moment from Huan Xian hole, qin panel upper end toward in audio amplifier, find bright object, mobile manipulator handle 6, string target seeker 1 upper end luminous position is made just to change string hole to for drawing, and under string target seeker 1 upper end luminous position makes background, see the string head for drawing string 10, promote driving wheel 5 simultaneously, between two upper belt pulleys 2 and bottom pulley 17 propelling movement under, make to pass from drawing string hole for drawing string 10, pull out string guide and can complete with left hand tractive string and draw string process.
