Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
The present invention includes speed gear A2, speed gear B15, trigger tooth wheel 4, detector switch 5, driving gear 6, stay cord 7, reel 8, gear installing plate 14 and base 10, gear installing plate 14 is fixedly connected with base 10 by securing member, reel 8 to be arranged between gear installing plate 14 and base 10 and to be fixed on axle I, one end of axle I is connected with base 10, the other end passes gear installing plate 14, and driving gear 6 is fixed on the other end of axle I; Speed gear A2 and speed gear B15 is fixed on axle II, and axle II one end is connected with gear installing plate 14; Described trigger tooth wheel 4 is made up of all gear and cam, and trigger tooth wheel 4 is fixed on axle IV, and one end of axle IV is connected with gear installing plate 14; Driving gear 6 engages with speed gear B15, and speed gear A2 engages with all gear in trigger tooth wheel 4, and detector switch 5 is arranged on the gear installing plate 14 of trigger tooth wheel 4, and stay cord 7 is wrapped on reel 8.
As shown in Figures 2 to 5, because all gear diameter in trigger tooth wheel 4 in above-mentioned scheme can be larger, be not easy to the use of staff, diminish to make all gear diameter in trigger tooth wheel 4, increase at least one group of driving gear set, described driving gear set is made up of transmission gear A3 and transmission gear B16, and transmission gear A3 and transmission gear B16 is fixed on axle III, and axle III one end is connected with gear installing plate 14; Speed gear A2 is engaged with transmission gear A3, and transmission gear B16 engages with all gear in trigger tooth wheel 4; Carrying out indirect transfer by increasing driving gear set, effectively can reduce all gear diameter in trigger tooth wheel 4, being convenient to installation and the use of staff.
As shown in Figure 1, also comprise protective cover 1, protective cover 1 is arranged on base 10, and described speed gear A2, speed gear B15, transmission gear A3, transmission gear B16, trigger tooth wheel 4, detector switch 5, driving gear 6, stay cord 7, reel 8 and gear installing plate 14 are placed in protective cover 1; Increase the normal work that protective cover 1 effectively can ensure each gear, improve stability of the present invention and serviceable life.
As a modification of the present invention, also comprise wind spring 9, wind spring 9 is arranged on reel 8 side; After increase wind spring 9 can terminate in stay cord 7 use of stretching out, automatic traction reel 8 turns round, and then the stay cord 7 stretched out is wound on reel 8, is convenient to use next time.
As a modification of the present invention, also comprise wire installation 17, it is outside that wire installation 17 is fixed on protective cover 1; Stay cord can be wrapped in uniformly on winding roll 8 during automatic retracted on winding roll 8, be convenient to use next time.
Improve as another kind of the present invention, also comprise locking device 13, locking device 13 is fixed on the afterbody of stay cord leading-out terminal; After sensor is finished using, physical characteristics due to wind spring 9 can drive reel 8 to make automatic the returning of stay cord 7 twine on reel 8 along the direction rotation that stay cord 7 bounces back, after the stroke of wind spring 9 terminates, have one section continue to be wound on reel 8 because inertia effect remains the stay cord 7 be not wound around, the length being wound into stay cord 7 on reel 8 will be caused like this to be greater than the maximum range of sensor and then measurement can be made inaccurate; The measuring accuracy of stay cord 7 during in order to ensure that next time uses, by locking device 13 by fastening for the measurement end of stay cord 7, makes stay cord 7 can not proceed to be wound around by inertia effects after wind spring 9 stops, ensure that the precision that next time measures.
Described detector switch 5 is contact detection switch or non-contact detection switch.
First measure the pulling rope length of required record before the use, then by regulating transmission gear B16 and the initial engagement angle both trigger tooth wheel 4, when the jut of trigger tooth wheel 4 cam in stay cord pull-out process is contacted with detector switch 5, the pulling rope length measured before just in time reaching, completes adjustment process.During use, stay cord 7 is reserved certain length, and itself and the movable part tail end detecting supporting leg are fixed; When supporting leg stretches out, stay cord 7 can drive driving gear 6 and wind spring 9 to rotate along with supporting leg extends, along with this to be rotated through all gear that power to be reached trigger tooth wheel 4 by speed gear A2, speed gear B15 and transmission gear A3, transmission gear B16 by the rotation of driving gear 6, trigger tooth wheel 4 is rotated thereupon; When stay cord 7 is elongated to certain length, the jut of the cam of trigger tooth wheel 4 can rotate to detector switch 5 side and then detection trigger switch 5; Now detector switch 5 action output switch amount signal, and being gone out by signal transmission by cable 11 and cable splice 12, because horizontal support legs overhang is the length that stay cord stretches out; Therefore staff clearly can know now horizontal support legs overhang.Due to transmission gear B16 and trigger tooth wheel 4, both initial engagement adjustable angle, only need complete above-mentioned adjustment process, this linear transducer just can export the on-off model of random length as required; Be convenient to the overhang that staff understands horizontal support legs.If when needing in addition to draw many group leaders degrees of data when extending with a supporting leg, by extending shaft I, then one group of speed gear A2, speed gear B15, transmission gear A3, transmission gear B16, trigger tooth wheel 4, detector switch 5, driving gear 6 and gear installing plate 14 is increased, its meshing relation is with the same before, but different with before of the tooth matching angle of the initial trigger tooth wheel 4 of this group and transmission gear B16, so just can measure many group leaders degrees of data when a supporting leg elongation together.
