[0015] The present invention provides an urban planning surveying and mapping instrument with an anti-dumping mechanism. It has the following beneficial effects: 1. The urban planning surveying instrument with an anti-dumping mechanism drives the bottom of the support rod to expand outward through the downward movement of the moving ring to finally form a triangular support foot to support the surveying instrument body. After installation, the limit rod is set horizontally. The three limit rods cooperate with each other to keep the three support rods expanding outward at the same angle, so that the surveying instrument body is always in a horizontal state, which greatly improves the measurement accuracy of the surveying instrument and avoids the need to repeatedly adjust the position of the support rod to reduce the measurement efficiency. At the same time, when the surveying instrument is folded, the support rod is restrained by the moving ring and the limit rod to avoid the problem that the support rod swings randomly and is difficult to place when it is folded. When the sleeve moves downward, the mounting frame rotatably connected to the sleeve will also move downward, and the mounting frame will drive the support rod to move downward. However, due to the limiting effect of the slider and the limit rod, the support rod will expand outward along the slider, and the moving wheel moves with the outward movement of the support rod, so that the clamping surface formed by the three support rods is gradually enlarged, which greatly increases the difficulty of the surveying instrument to flip, thereby greatly improving the stability during work, and realizing automatic expansion to a corresponding scale according to the wind force to enhance the wind resistance of the surveying instrument.
[0016] 2. The urban planning surveying and mapping instrument with an anti-tilt mechanism can make the rotating disk rotate in the opposite direction after use is completed, and the rotation of the rotating disk drives the sliding rod to slide in the sliding groove, and the sliding rod drives the bottom rotating ring to rotate, and the rotating ring drives the second clamping plate to rotate through the mounting rod, so that the second clamping plate is disengaged from the first clamping plate. At this time, due to the squeezing effect of the accommodating groove on the limiting tube, the first clamping plate is retracted inwardly along the accommodating groove, and the wind force plate and the rotating cover begin to reset under the action of torque, that is, the sleeve is moved upward along the first telescopic rod, driving the mounting frame and the support rod to rotate inwardly and retract, that is, after the work is completed, the rotating disk can be reversed to automatically retract the outward expansion range of the support rod, which greatly improves the degree of automation and greatly improves the convenience of use. Then, the moving ring can be driven upward to make the bottom of the support rod retract inward to complete the overall storage. The operation is simple and convenient to use, which greatly improves the applicability of the surveying and mapping instrument.
[0017] 3. In the urban planning surveying instrument with an anti-dumping mechanism, in the process of initially driving the moving ring downward, the moving ring moves downward so that the second telescopic rod is squeezed and compressed, that is, the volume of the internal cavity of the second telescopic rod is reduced, and the air pressure is increased, that is, the internal air pressure is transmitted to the air pressure groove, so that the air pressure in the air pressure groove is increased, thereby pushing the third telescopic rod to extend outward, and the third telescopic rod drives the expansion tube to move outward, and the expansion rods at both ends of the expansion tube slide outward and expand accordingly, and extend out from the first storage groove and the second storage groove, that is, the expansion tube and the expansion rod form a larger nearly circular shape, which greatly increases the ground contact area, thereby further increasing the difficulty of the surveying instrument to reverse and dump, and further greatly improving the working stability of the entire surveying instrument, and at the same time, the expansion of the expansion tube and the expansion rod is automatically realized when the surveying instrument is initially placed, that is, further improving the convenience of use of the surveying instrument, and when the surveying instrument is folded, the second telescopic rod expands, so that the air pressure in the third telescopic rod is released, automatically driving the expansion tube and the expansion rod to reset and complete storage, further improving the automation level of the surveying instrument.

[0025] The inner surface of the rotating cover 312 is rotatably connected to a first clamping plate 316 via a torsion spring. Three first clamping plates 316 are arranged at fixed intervals around the central axis of the rotating cover 312. The three first clamping plates 316 are arranged at an angle.

The bearing plate 327 is fixedly connected to the bottom inner surface of the mounting ring 311.
[0028] During operation, if the surveying instrument needs to be used, the surveying instrument body 1 can be installed on the mounting platform 2, and the surveying instrument can be moved to a designated position to place the surveying instrument vertically. Then, the moving ring 38 is driven to move downward along the first telescopic rod 31, and is engaged at the bottom of the first telescopic rod 31. The downward movement of the moving ring 38 drives the bottom of the support rod 34 to expand outward to finally form a triangular support leg to support the surveying instrument body 1. After the installation is completed, the limit rod 37 is horizontally arranged, and the three limit rods 37 cooperate with each other to make the three support rods 34 move outward. The angle of outward expansion remains the same, so that the surveying instrument body 1 is always in a horizontal state, which greatly improves the measurement accuracy of the surveying instrument and avoids the need to repeatedly adjust the position of the support rod 34 to reduce the measurement efficiency. At the same time, when it is folded, the support rod 34 will be restrained by the movable ring 38 and the limit rod 37 to avoid the problem of the support rod 34 swinging around and being difficult to place when stored. When the wind blows, the wind force acts on the wind plate 313, and the wind plate 313 is affected by the wind force and begins to drive the rotating cover 312 to rotate along the central axis of the mounting ring 311.Because there is a torsion force between the rotating cover 312 and the mounting ring 311 and the rotating cover 312 is connected to the connecting ring 310 through the connecting rod 314 and the transfer rod 315, the rotating cover 312 will drive the connecting ring 310 to rotate when it rotates, and the rotation of the connecting ring 310 causes the sleeve 32 to have a rotation trend, but because the sleeve 32 is threadedly connected to the first telescopic rod 31, the sleeve 32 cannot rotate freely, but moves downward along the first telescopic rod 31 under the action of the thread, when the sleeve 32 moves downward, the mounting frame 33 rotatably connected to the sleeve 32 will also move downward, and when the mounting frame 33 moves downward, it drives the support rod 34 to move downward, but due to the limiting effect of the slider 36 and the limiting rod 37, the support rod 34 will expand outward along the slider 36, and the moving wheel 35 moves with the outward movement of the support rod 34, so that the clamping surface formed by the three support rods 34 is gradually enlarged, which greatly increases the difficulty of the surveying instrument to flip, and then greatly improves the stability during work, and realizes automatic expansion to the corresponding scale according to the wind force to enhance the wind resistance of the surveying instrument, and when using After completion, the rotating disk 325 can be rotated in the opposite direction, and the rotating disk 325 rotates to drive the sliding rod 324 to slide in the sliding groove 323, and the sliding rod 324 drives the bottom rotating ring 322 to rotate, and the rotating ring 322 drives the second clamping plate 320 to rotate through the mounting rod 321, so that the second clamping plate 320 and the first clamping plate 316 are disengaged. At this time, due to the squeezing effect of the receiving groove 319 on the limiting tube 318, the first clamping plate 316 is retracted inwardly along the receiving groove 319, and the wind plate 313 and the rotating cover 312 are in a torsion state. The reset begins under the action of force, that is, the sleeve 32 moves upward along the first telescopic rod 31, driving the mounting frame 33 and the support rod 34 to rotate inward and retract, that is, after the work is completed, the rotating disk 325 can be reversed to automatically retract the outward extension of the support rod 34, which greatly improves the degree of automation and greatly improves the convenience of use. Then, the moving ring 38 is driven upward to make the bottom of the support rod 34 retract inward to complete the overall storage. The operation is simple and easy to use, which greatly improves the applicability of the surveying instrument.
[0029] Second embodiment: Figures 1 to 8 As shown, the protective mechanism 4 includes a second telescopic rod 41, the top outer surface of the second telescopic rod 41 is fixedly connected to the inner surface of the movable ring 38, the bottom of the second telescopic rod 41 is fixedly connected to a carrying plate 42, and the inner surface of the carrying plate 42 is fixedly connected to the bottom outer surface of the first telescopic rod 31.
[0030] The lower surface of the supporting plate 42 is fixedly connected to the mounting plate 43, and the bottom outer surface of the mounting plate 43 is provided with a first receiving groove 44, and the first receiving groove 44 is arranged in a ring shape. The upper surface of the mounting plate 43 is penetrated by a second receiving groove 45, and the interior of the mounting plate 43 is provided with an air pressure groove 46, and the air pressure groove 46 is connected with the internal cavity of the second telescopic rod 41, and a third telescopic rod 47 is fixedly connected in the air pressure groove 46, and the outer end of the third telescopic rod 47 is fixedly connected with an expansion tube 48, and the two ends of the expansion tube 48 are slidably connected with expansion rods 49, and the expansion rod 49 and the expansion tube 48 are combined into a nearly circular shape, and the middle part of the expansion rod 49 is arranged in a U shape.
[0031] During operation, at the beginning of the process of driving the moving ring 38 downward, the moving ring 38 moves downward so that the second telescopic rod 41 is squeezed and compressed, that is, the volume of the internal cavity of the second telescopic rod 41 is reduced, and the air pressure is increased, that is, the internal air pressure is transmitted to the air pressure groove 46, so that the air pressure in the air pressure groove 46 is increased, thereby pushing the third telescopic rod 47 to extend outward, and the third telescopic rod 47 drives the expansion tube 48 to move outward, and the expansion rods 49 at both ends of the expansion tube 48 slide outward and expand accordingly, extending from the first receiving groove 44 and the second receiving groove 45, that is, the expansion tube 48 and the expansion tube 48 are extended. The rod 49 forms a relatively large nearly circular shape, which greatly increases the ground contact area, thereby further increasing the difficulty of the surveying instrument to reverse and tip over, and further greatly improving the working stability of the entire surveying instrument. At the same time, the expansion of the expansion tube 48 and the expansion rod 49 is automatically achieved when the surveying instrument is initially placed, which further improves the ease of use of the surveying instrument. When the surveying instrument is folded up, the second telescopic rod 41 expands, so that the air pressure in the third telescopic rod 47 is released, which automatically drives the expansion tube 48 and the expansion rod 49 to reset and complete the storage, further improving the degree of automation of the surveying instrument.
