[0026] Embodiment 1

[0027] Reference Figures 1-5 For the first embodiment of the present application, the embodiment provides a surveying and mapping table for mountainous terrain surveying and mapping, comprising,

[0028] The support mechanism 100 comprises a mounting seat 101, a connecting groove 102 is formed in the top of the mounting seat 101, a joint 103 is hinged on the side wall of the mounting seat 101, an upper rod 104 is fixedly installed at the bottom of the joint 103, a first connecting block 105 is sleeved on the side wall of the upper rod 104, a second connecting block 106 is fixedly installed at the bottom of the upper rod 104, a lower rod 107 is fixedly installed at the bottom of the first connecting block 105, a support block 108 is fixedly installed at the bottom of the lower rod 107, a support leg 109 is fixedly connected to the bottom of the support block 108, and a telescopic assembly 110 is arranged on the side wall of the joint 103;

[0029] The adjusting mechanism 200 comprises a mounting shell 201, a handle 202 fixedly installed on the side wall of the mounting shell 201, and a rotating shell 203 movably connected to the inner wall of the mounting shell 201, wherein an inner cavity of the rotating shell 203 is provided with a limiting groove 204, and the inner wall of the limiting groove 204 is provided with a locking assembly 205.

[0030] Specifically, the side wall of the lower rod 107 is slidably connected with a second connecting rod 205e, and the upper rod 104 and the lower rod 107 are staggered with the first connecting block 105 and the second connecting block 106, and do not affect each other during extension and retraction, thereby ensuring smooth extension and retraction.

[0031] The telescopic assembly 110 comprises a lead screw 110a fixedly installed at the bottom of the joint 103, a limiting cylinder 110b sleeved on the outer surface of the lead screw 110a, a fixed ring 110c fixedly installed at the end of the limiting cylinder 110b, a half-thread sleeve 110d slidably connected to the inner wall of the fixed ring 110c, a top spring 110e fixedly installed on the side wall of the half-thread sleeve 110d, a sliding block 110f fixedly installed at the top of the half-thread sleeve 110d, a sliding rail 110g slidably connected to the outer surface of the sliding block 110f, and a pushing block 110h fixedly connected to the side wall of the sliding rail 110g.

[0032] Further, the two half-thread sleeves 110d are connected by the top spring 110e, and when the two half-thread sleeves 110d are placed in the fixed ring 110c, the two half-thread sleeves 110d form a complete thread sleeve, and the lead screw 110a can be driven through the thread.

[0033] The locking assembly 205 comprises a threaded stud 205b threadedly connected to the inner wall of the limiting groove 204, a knob 205a fixedly installed at the end of the threaded stud 205b, an abutting block 205c movably connected to the outer surface of the threaded stud 205b, a friction ring 205d fixedly installed at the end of the abutting block 205c, a connecting rod 205e movably connected to the inner wall of the friction ring 205d, and the end of the connecting rod 205e is fixedly connected to the inner wall of the mounting shell 201.

[0034] Preferably, the knob 205a is pushed, the knob 205a drives the threaded stud 205b to rotate, and the threaded stud 205b can move forward and backward in cooperation with the limiting groove 204, when the threaded stud 205b moves to the bottom of the limiting groove 204, the threaded stud 205b lifts the abutting block 205c, drives the friction ring 205d to abut against the connecting rod 205e, and completely brakes the connecting rod 205e.

[0035] In use, after the device is placed on the ground, the dial block 110h is removed, and the upper rod 104 and the lower rod 107 are used in cooperation with the first connecting block 105 and the second connecting block 106, which can quickly adjust the height of the device. After the approximate height of the device is determined, the dial block 110h is inserted into the fixed ring 110c through the half-thread sleeve 110d, and the two half-thread sleeves 110d are locked by threads through the screw rod 110a. The height of the device can be fine-tuned and locked by dialing the dial block 110h, which drives the half-sleeve to rotate and drives the screw rod 110a to move up and down through the threads. By adjusting the strip legs 109 respectively, the device can adapt to different mountain conditions. After the height of the device is determined, the surveying instrument is connected through the installation shell 201, and the horizontal direction of the device can be adjusted by the handle 202. When measuring the depression angle or the elevation angle, the knob 205a is dialed, the knob 205a drives the stud 205b to move backward, the block 205c falls downward relying on its own gravity, the friction ring 205d moves away from the connecting rod 205e, and the limiting of the connecting rod 205e is released. At this time, the angle of the instrument in the vertical direction can be adjusted by the handle 202. After adjustment is completed, the knob 205a is dialed, the knob 205a drives the stud 205b to move forward, and when the stud 205b moves to the bottom of the limiting slot 204, the block 205c is pushed upward, and the block 205c cooperates with the friction ring 205d to completely brake the connecting rod 205e.

[0036] In summary, rapid and accurate height adjustment is achieved, and the use of half-thread sleeves 110d ensures the stability and locking of the height, so that the device can adapt to different mountain terrains and maintain a stable measurement platform. In addition, the independent adjustment function of the strip legs 109 further enhances the adaptability of the device. During the measurement process, the handle 202 and the knob 205a can be easily operated to adjust the horizontal and vertical directions of the surveying instrument, ensuring the accuracy of measuring the depression angle or the elevation angle. The braking system of the block 205c and the friction ring 205d ensures the stability of the instrument after adjustment, greatly improving the efficiency and safety of surveying work.
