One end of the sliding rod 74 is provided with a pull ring, a limiting spring is sleeved outside the sliding rod 74, one end of the limiting spring is connected with the pull ring, and the other end of the limiting spring is connected with the wall surface of the mounting seat 71, so that the displacement of the sliding rod 74 is limited when the sliding rod is pulled to move.
It can be seen that, in the embodiment, a manual driving source is provided by the pull ring, the sliding fit between the sliding rod 74 and the mounting seat is provided, and the elastic limiting support is provided by the limiting spring, so that the clamping seat 72 and the positioning convex body 721 are clamped and fixed with the positioning hole 731, thereby facilitating the surveying and mapping personnel to quickly mount and dismount the rotating shaft 73 and the mounting seat 71.
The working process of the invention is as follows: when the device is used, a surveying and mapping staff firstly buckles the pull ring and exerts force outwards respectively, the pull ring drives the slide rod to move inwards and outwards in the mounting seat and also drives the limiting spring to extrude and compress, so that the limiting spring deforms and accumulates elastic potential energy inside the limiting spring, then the surveying and mapping staff inserts the rotating shaft at the bottom of the range finder body into the limiting groove in the mounting seat, then the surveying and mapping staff loosens the pull ring, the limiting spring in an extrusion compression state loses tension, the limiting spring accumulating elastic potential energy forces the slide rod to drive the positioning lug to be inserted into the corresponding positioning hole through the clamping seat, the quick mounting between the range finder body and the mounting seat can be realized, after the surveying and mapping staff reaches a site ranging preset position, the electric push rod is started to drive the push seat to push downwards, meanwhile, the push seat drives the slide block to slide downwards in the sliding groove for supporting, and space is provided by the through groove, thereby push away the seat and drive three group in step and adjust the outside extension of pole, because be articulated between telescopic link and the solid fixed cylinder and connect, the telescopic link is sliding connection with the bracing piece, thereby three group adjust the pole and drive three spinal branch vaulting poles abduction to preset position, then surveying personnel places the pedestal of three spinal branch vaulting pole bottoms at place preset position again, and insert ground with the positioning seat, the rethread pedestal of many spinal branchs poles respectively and inserts ground, can steadily support the distancer body, surveying personnel reuse the distancer body and carry out the range finding operation to the place.
In conclusion, the adjusting mechanism is arranged, the electric push rod provides a driving source, and the pushing seat and the three groups of adjusting rods are matched in an expanding way, so that the supports of all groups can be driven to synchronously unfold to a preset position, the condition that the supports are not unfolded in place is avoided, the ranging state stability of the range finder body is ensured, the accuracy of the ranging result of the range finder body is improved, and the ranging efficiency of a surveying and mapping person on a field by using the range finder body is also improved; through the sliding fit between the sliding chute and the sliding block, the lifting stability of the pushing seat in the fixed cylinder is favorably ensured, the pushing seat is prevented from being inclined, and meanwhile, the pushing seat also has the functions of bearing and sharing the stress; the positioning convex body and the positioning block are arranged, so that the positioning and stabilizing effect of the rotating shaft is ensured; through setting up the pull ring and providing the manual drive source, the sliding fit of slide bar and sliding sleeve, provide the spacing support of elasticity by spacing spring, thereby it is fixed to the locating hole chucking through cassette and location convex body, the surveying and mapping personnel of being convenient for install fast and dismantle between countershaft and the mount pad, through setting up the spacing groove, the surveying and mapping personnel of being convenient for inserts the mount pad with the pivot fast, through the positioning seat, can carry out spacing fixed in advance to the supporting legs bottom, through setting up the locating lever, can further consolidate stably around the supporting legs, strengthen the overall stability effect of supporting leg and distancer body.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
