[0029] The utility model is further described below in conjunction with the accompanying drawings:
[0030] like Figure 1-Figure 7 As shown, a surveying pole for surveying and mapping engineering includes a folding mechanism, which includes a folding bracket 101. Two symmetrically arranged fixed shafts 106 are welded at the upper and lower ends of the folding bracket 101. A telescopic rod mechanism is arranged on the fixed shaft 106. The telescopic rod mechanism includes a first measuring rod 201 rotatably connected to the fixed shaft 106 by a bearing, a telescopic gear 204 is rotatably connected to the first measuring rod 201, and two telescopic racks 205 symmetrically arranged at the center of a circle are meshed on the side of the telescopic gear 204. The telescopic rack 205 is slidably connected to the first measuring rod 201, and a scissor frame 206 is rotatably connected to the top of the telescopic rack 205. The other end of the scissor frame 206 is slidably connected to the second measuring rod 207. The other end of the scissor frame 206 and the second measuring rod 207 can produce relative rotation and relative sliding. The second measuring rod 207 is slidably connected to the first measuring rod 201, and the bottom of the second measuring rod 207 on the lower side is fixedly connected with a fixing nail 208 by bolts, and the outer end of the second measuring rod 207 on the upper side is provided with Extension mechanism, a fixed bevel gear 202 is keyed on the fixed shaft 106, and a driving bevel gear 203 is fixedly connected to the telescopic gear 204 near the fixed shaft 106. The driving bevel gear 203 is meshed with the fixed bevel gear 202. During the rotation of the first measuring rod 201, relative rotation is generated with the fixed bevel gear 202. The first measuring rod 201 drives the driving bevel gear 203 to rotate, and the fixed bevel gear 202 drives the driving bevel gear 203 meshed with it to rotate. The driving bevel gear 203 drives the telescopic gear 204 to rotate, and the telescopic gear 204 drives the telescopic rack 205 to move. The two telescopic racks 205 drive the scissor frame 206 to extend or retract, and the extension or retraction of the scissor frame 206 drives the second measuring rod 207 to move. In this way, the surveying and mapping benchmark in the folded state is smaller in size and more convenient to carry. When in the folded state, the joint port 301 and the fixing nail 208 can be retracted into the first measuring rod 201, so as to protect the components while preventing the fixing nail 208 from stabbing the staff.
[0031] A rotating screw 103 is rotatably connected in the middle of the folding bracket 101, and a handle 102 is fixedly connected to one end of the rotating screw 103 by a bolt. A driving frame 104 is threadedly connected to the rotating screw 103, and the driving frame 104 is slidably connected to the folding bracket 101. Two flip racks 105 are fixedly connected to the upper and lower sides of the driving frame 104, and a flip gear 108 is fixedly connected to one end of the first measuring rod 201, and the flip gear 108 is meshed with the flip rack 105. A bubble leveler 107 is slidably connected to one side of the folding bracket 101 through a slide groove, and the bubble leveler 107 can be removed from the folding bracket 101 and can be used for surveying and mapping. When the rod is in the extended state, the bubble leveler 107 is installed to check and adjust the vertical angle of the surveying and mapping benchmark. The staff turns the handle 102, and the handle 102 drives the rotating screw 103 to rotate. The rotating screw 103 drives the driving frame 104 threadedly connected thereto to move, and the driving frame 104 drives the flip rack 105 to move, and the flip rack 105 drives the flip gear 108 to rotate, and the flip gear 108 drives the first measuring rod 201 to rotate. In this way, it can switch between the folded state and the extended state, which is convenient for surveying and mapping personnel to carry the surveying and mapping benchmark for position transfer, and improves the convenience of using the surveying and mapping benchmark.
[0032] The extension mechanism includes a coupling port 301 which is fixedly connected to one end of the second measuring rod 207 on the upper side with bolts, and two protrusions are symmetrically arranged on the upper end of the coupling port 301, and an extension rod 302 is arranged at the outer end of the coupling port 301. One end of the extension rod 302 is slidably connected to two symmetrically arranged limit pins 303, and the limit pin 303 and the protrusion on the upper end of the coupling port 301 can form a limit, and a spring 304 is fixedly connected between the limit pin 303 and the extension rod 302, and the upper end of the limit pin 303 extends to the surface of the extension rod 302. The staff presses the limit pin 303 to move inward, and the spring 304 contracts at this time to insert one end of the extension rod 302 into the coupling port 301, and then the staff releases the limit pin 303, and the limit pin 303 is reset under the action of the spring 304, and the lower end of the limit pin 303 and the protrusion on the coupling port 301 form a limit, so that when the length of the surveying and mapping benchmark needs to be increased, it can be quickly connected through modular external components, thereby achieving the effect of increasing the length of the surveying and mapping benchmark.
[0033] The interior of the second measuring rod 207 and the extension rod 302 is arranged as a cavity, and the front surfaces of the folding bracket 101, the first measuring rod 201, the second measuring rod 207 and the extension rod 302 are arranged with red and white scales. The arrangement of the cavity of the second measuring rod 207 and the extension rod 302 can lighten the surveying and mapping pole, thereby reducing the physical strength consumed by the staff in the process of carrying the surveying and mapping pole, and the scales arranged on the front surface make it convenient for the staff to read the data during the surveying and mapping process.
[0034] Working principle: After the staff carries the surveying and mapping pole to the measuring position, the staff rotates the handle 102, and the handle 102 drives the rotating screw 103 to rotate, and the rotating screw 103 drives the driving frame 104 threaded thereon to move, and the driving frame 104 drives the flip rack 105 to move, and the flip rack 105 drives the flip gear 108 to rotate, and the flip gear 108 drives the first measuring rod 201 to rotate, and the first measuring rod 201 rotates relative to the fixed bevel gear 202 during the rotation process, and the first measuring rod 201 drives the driving bevel gear 203 to rotate, and the fixed bevel gear 202 drives the driving bevel gear 203 meshing therewith to rotate, and the driving bevel gear 203 drives the telescopic gear 204 to rotate, and the telescopic gear 204 drives the telescopic rack 205 to move, and the two telescopic racks 205 drive The scissors frame 206 is extended, and the extension of the scissors frame 206 drives the second measuring rod 207 to move outward, and the coupling port 301 and the fixing nail 208 are extended to the outside of the coupling port 301, thus completing the extension of the surveying and mapping benchmark. The tester then holds the handle 102 to align the fixing nail 208 with the measuring coordinate point and the front side with the observer. When the surveying and mapping benchmark needs to be extended, the staff presses the limit pin 303 to move inward. At this time, the spring 304 contracts and inserts one end of the extension rod 302 into the coupling port 301. The staff then releases the limit pin 303, and the limit pin 303 is reset under the action of the spring 304. The lower end of the limit pin 303 and the protrusion on the coupling port 301 form a limit, and the scale set on the front surface is convenient for the staff to read data during the surveying and mapping process.
