Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping instruments, in particular to a portable surveying and mapping instrument. Background Art

[0002] A surveying instrument is a professional instrument used for geospatial data collection, measurement and mapping. It can be used to measure and record various data on the ground.

[0003] According to a disclosed portable surveying instrument (publication number: CN220727813U), in the above application, by providing a handle and a hanging strap, the user can fix the surveying instrument body to the user's body through the hanging strap, thereby reducing the burden on the arm and providing more stable support. By providing a support member and a strap, the measurement error caused by hand shaking or unstable support is reduced and it is convenient to carry.

[0004] However, in actual use of the above equipment, although the support plays a stabilizing role and is convenient for retracting and carrying, it will cause the threaded nails to rotate and loosen if accidentally touched by the outside world, and eventually cause the whole device to collapse. In view of this, we propose a portable surveying instrument. Utility Model Content

[0005] The purpose of the utility model is to provide a portable surveying and mapping instrument to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable surveying and mapping instrument comprises a surveying and mapping scanning head, one end of the surveying and mapping scanning head is fixedly connected to a support plate, the outer surface of the support plate is provided with a support assembly, one end of the support assembly is provided with an insertion head, the support assembly comprises a fixing frame, the outer surface of the support plate is provided with a fixing frame, the outer surface of the fixing frame is movably connected with a clamping block, one end of the clamping block is rotatably installed with a twist, one end of the twist passes through the clamping block and is fixedly connected with a threaded rod, a sliding groove is provided on the outer surface of the clamping block, the outer surface of the sliding groove is fixedly connected with a spring, one end of the spring is fixedly connected with an L-shaped block, one end of the L-shaped block is fixedly connected with an L extrusion block, and the L-shaped block One end is fixedly connected with an inclined block, the outer surface of the threaded rod is threadedly connected with a threaded slider, the outer surface of the threaded slider is fixedly connected with a limiting rod, the limiting rod is movably connected with a clamping block, the outer surface of the threaded slider is provided with an elastic telescopic pile, one end of the elastic telescopic pile is fixedly connected with a fixed block, one end of the threaded rod is provided with an elastic saber-tooth pile, the outer surface of the fixed block is provided with a saber-tooth groove, the outer surface of the fixed frame is movably connected with an extension frame, the outer surface of the extension frame is provided with a rotating clamping slot, the outer surface of the extension frame is provided with a limited position long slot, the outer surface of the threaded rod is movably connected with a rotating clamping slot, the outer surface of the fixed block is movably connected to the limited position long slot, and the outer surface of the elastic telescopic pile is fixedly connected with a lifting pile.

[0007] Preferably, the outer surface of the inclined block is movably connected with a lifting pile, so that the inclined block can squeeze the lifting pile when it is squeezed forward, so that the elastic telescopic pile is stretched.

[0008] Preferably, the saber-tooth groove is matched with the elastic saber-tooth pile, so that the elastic saber-tooth pile can be fixed when the saber-tooth groove descends.

[0009] Preferably, the center line of the threaded slider, the center line of the fixed block and the center line of the stretching frame are all in the same plane, so that the whole can run stably.

[0010] Preferably, a fixing assembly is provided at one end of the lifting pile, and the fixing assembly includes an elastic expansion plate. An elastic expansion plate is provided at one end of the lifting pile, and a fixing opening is provided on the outer surface of the fixing frame.

[0011] Preferably, the elastic expansion plate is movably connected with a fixing opening, so that one end of the elastic expansion plate can be inserted into the fixing opening.

[0012] Compared with the prior art, the utility model provides a portable surveying and mapping instrument, which has the following beneficial effects:

[0013] 1. When the portable surveying instrument is fixed in daily life, the threaded rod and the elastic saber-tooth pile are put into the rotating slot by moving the twister forward. After the twister is rotated, the elastic saber-tooth pile is blocked by the rotating slot and cannot be pulled out. When the threaded rod is rotated, the threaded slider moves forward, so that the fixed block enters the limit long groove, and the elastic saber-tooth pile is further fixed in the saber-tooth groove, so that the fixed frame and the extension frame will not be loose. When the limit is released, the L extrusion block is pressed to move the inclined block forward to extrude the lifting pile, which will cause the saber-tooth groove to lift and no longer fix the elastic saber-tooth pile. The twister can be rotated to remove the block, and finally the twister will not rotate when accidentally touched by the outside world, so that the fixed frame and the extension frame will not be loose.

[0014] 2. For the portable surveying instrument, when the fixed block moves forward, the elastic expansion plate will run synchronously, so that the elastic expansion plate enters the fixed opening, realizing the third limiting effect, and when releasing the limit, it is only necessary to press the elastic expansion plate in the fixed opening outside the fixed frame, and at the same time, when the extension frame is loosened, the block and the twist knob will not be separated from the fixed frame, finally realizing multiple limiting and making it impossible to find the block and the twist knob if they are lost by accident.
