DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0025] The present embodiment provides a field surveying and mapping device, which is mainly used to solve the problem that when the user rotates the telescopic rod of the existing laser RTK measuring instrument to a large extent, the threaded connection between the measuring instrument body and the telescopic rod will gradually loosen due to the effect of inertia, and provides the following technical solutions. Figure 1-Figure 5 Make a detailed description:

[0026] A field surveying and mapping device comprises a measuring instrument body 1 and a telescopic rod 2 threadedly connected to the lower part of the measuring instrument body 1. When in use, the user can control the length of the telescopic rod 2 to control the measuring range of the upper measuring instrument body 1. Baffles 3 are arranged on both sides of the measuring instrument body 1. Under the action of a limiting mechanism 4, the relative positions of the two baffles 3 and the telescopic rod 2 remain unchanged, that is, when the measuring instrument body 1 rotates, due to the obstruction of the two baffles 3, the threaded connection between the measuring instrument body 1 and the telescopic rod 2 will not loosen. At the same time, the user can release the relative position of the two baffles 3 and the telescopic rod 2 through the limiting mechanism 4, thereby disassembling the measuring instrument body 1 and the telescopic rod 2. It should be noted that the telescopic rod 2 is a common prior art, and its telescopic mode is various. Common ones include threaded telescopic or controlling the position of the cannula on the inner wall of the empty tube to achieve control of the total length of the cannula and the empty tube. The telescopic tube principle of the present device is similar to the principle of telescopic of the sweeping handle, which will not be elaborated here. The main components of the limiting mechanism 4 are: a mounting plate 401 slidably sleeved on the surface of the connecting rod 6, and the two baffles 3 are both mounted on the surface of the mounting plate 401. When in use, the user first slides the mounting plate 401 on the surface of the non-threaded groove part of the connecting rod 6 and makes the mounting plate 401 fit on the surface of the placement plate 5, and then sets the measuring instrument body 1 in the middle of the baffle 3 so that the connecting rod 6 is threadedly inserted into the bottom of the measuring instrument body 1, and finally rotates the blocking block 402 to the surface of the mounting plate 401 through the mounting mechanism 7 and controls its rotation angle so that the surface of the blocking block 402 fits on the surface of the mounting plate 401, so that when the measuring instrument body 1 has a tendency to rotate, it will drive the mounting plate 401 to have a tendency to rotate synchronously, and at this time, the rotation tendency of the mounting plate 401 will be blocked by the blocking block 402, thereby avoiding the loosening of the threaded connection between the measuring instrument body 1 and the telescopic rod 2 (i.e., the threaded connection between the connecting rod 6 and the measuring instrument body 1) due to the rotation of the measuring instrument body 1.

[0027] In the above scheme, a telescopic rod 2 is provided with a thread installed under the measuring instrument body 1, so that when in use, the user can hold the telescopic rod 2 to drive the upper measuring instrument body 1 to move, so as to realize the surveying and mapping of the surrounding buildings. Compared with the prior art, baffles 3 are provided on both sides of the measuring instrument body 1 of the device. At the same time, under the action of the limiting mechanism 4, the relative positions of the two baffles 3 and the telescopic rod 2 remain unchanged, so that even if the user rotates the measuring instrument body 1 significantly, the threaded connection between the measuring instrument body 1 and the telescopic rod 2 is difficult to loosen due to the obstruction of the two baffles 3, thereby improving the surveying and mapping effect.

[0028] In the above scheme, a foot pedal 8 is provided on the surface of the telescopic rod 2, so that when performing surveying operations on a slope, the user can insert the telescopic rod 2 into the slope soil, and then step on the foot pedal 8 to limit the telescopic rod 2 on the slope, thereby ensuring the stability of the measuring instrument body 1 during the measurement process.

[0029] like Figure 3 As shown, in some embodiments, the main components of the mounting mechanism 7 are: a mounting rod 701 fixedly mounted on the surface of the mounting plate 401. When in use, the user first slides the blocking block 402 onto the surface of the mounting rod 701, and then threadedly inserts the abutment bolt 702 into one end of the mounting rod 701, so that the surface of the abutment bolt 702 abuts against the surface of the blocking block 402, thereby achieving the installation of the blocking block 402 on the surface of the mounting rod 701 and limiting the position of the mounting plate 401.

[0030] like Figure 4 and Figure 5 As shown, in some embodiments, a foot pedal 8 is provided on one side of the telescopic rod 2, and an adjustment mechanism 9 is also included. The adjustment mechanism 9 is used to install the foot pedal 8 on the surface of the telescopic rod 2 and control the position of the foot pedal 8 along the length direction of the telescopic rod 2, wherein the adjustment mechanism 9 comprises: an adjustment groove 901 provided on the surface of the telescopic rod 2, and an adjustment ring 902 is slidably sleeved on the inner wall of the adjustment groove 901. When the user inserts the telescopic rod 2 into the soil, the foot pedal 8 installed on the surface of the adjustment ring 902 is rotated by two torsion springs 903 to fit on the ground and drive the adjustment ring 902 to slide on the inner wall of the adjustment groove 901. Finally, the user steps on the foot pedal 8 to avoid the situation where the upper measuring instrument body 1 drives the telescopic rod 2 to tilt under the action of gravity.

[0031] like Figure 5 As shown, in some embodiments, the two torsion springs 903 are installed as follows: a mounting groove 10 is provided on the surface of the adjusting ring 902 and a fixing rod 11 is fixedly installed on the inner wall of the mounting groove 10, a fixing rod 11 is fixedly installed on the inner wall of the mounting groove 10, and the foot pedal 8 is rotatably sleeved on the surface of the fixing rod 11, and the two torsion springs 903 are rotatably sleeved on the surface of the fixing rod 11, one end of the two torsion springs 903 is respectively fixedly installed on both sides of the foot pedal 8, and the other ends of the two torsion springs 903 are respectively fixedly installed on both sides of the inner wall of the mounting groove 10. When the user inserts the telescopic rod 2 into the ground and steps on the foot pedal 8, the foot pedal 8 will rotate relative to the mounting groove 10 provided on the surface of the adjusting ring 902, thereby causing the two torsion springs 903 to twist. After the measurement is completed, the user releases the foot pedal 8, and under the action of the two torsion springs 903, the foot pedal 8 will reset. The surface of the foot pedal 8 is provided with a plurality of friction grooves 12 for increasing the friction between the user's foot and the foot pedal 8.

[0032] The workflow of this utility model:

[0033] First, the user slides the mounting plate 401 onto the surface of the connecting rod 6 so that the mounting plate 401 fits against the surface of the placement plate 5, then sets the measuring instrument body 1 between the two baffles 3, rotates the telescopic rod 2, so that the connecting rod 6 rotates on the inner wall of the mounting plate 401, so that the connecting rod 6 is threadedly inserted into the bottom of the measuring instrument body 1, and finally slides the blocking block 402 onto the surface of the mounting rod 701, and threadably inserts the interference bolt 702 into one end of the mounting rod 701, so that the surface of the interference bolt 702 is in contact with the surface of the blocking block 402, thereby achieving the limiting of the blocking block 402 on the surface of the mounting rod 701, which is also the limiting of the mounting plate 401 above the placement plate 5 (when the mounting plate 401 is driven by the measuring instrument body 1, it will be in contact with the surface of the blocking block 402 and cannot rotate).

[0034] Secondly, in some surveying and mapping environments, the user needs to conduct surveying and mapping on a slope. In this case, the telescopic rod 2 needs to be inserted into the ground, and then the foot pedal 8 needs to be stepped on so that the foot pedal 8 fits on the ground to further fix the telescopic rod 2.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
