1-7, the present utility model provides a technical solution: a cadastral surveying and mapping centering rod, comprising a bottom plate 1, the upper surface of the bottom plate 1 is provided with a first chute 2, and the inner side wall of the first chute 2 slides The first plate body 3 is connected. The outer side wall of the first plate body 3 is provided with second threaded through holes 18 on both sides. Bottom plate 1, one side of the first plate body 3 is provided with a second chute 4, the inner side wall of the second chute 4 is slidably connected with a second plate body 5, and both sides of the outer side wall of the second plate body 5 are evenly opened with The first threaded through hole 6, the inner side wall of the first threaded through hole 6 is threadedly connected with a first bolt 7, the first bolt 7 penetrates the first plate body 3, and one side of the first plate body 3 is fixedly connected with a third plate body 8.

In this embodiment, specifically: the upper surface of the third plate body 8 is fixedly connected with the fourth plate body 9 and the fifth plate body 11 , one side of the fifth plate body 11 is threadedly connected with a threaded rod 12 , and the threaded rod 12 is One end is fixedly connected with a knob 13, the other end of the threaded rod 12 is rotatably connected with a bearing 14, and the outer side wall of the bearing 14 is rotatably connected with a sixth plate body 15, which prevents the surveying instrument from being on the third plate body 8, close to the fourth plate body 9. Through the setting of the fifth plate body 11 and by rotating the knob 13, the threaded rod 12 is driven to rotate on the fifth plate body 11 to push the sixth plate body 15, and the threaded rod 12 is set through the bearing 14. The sixth plate body 15 plays a role of pushing and will not drive it to rotate, which is convenient and better to fix the surveying and mapping instrument.

In this embodiment, specifically: one side of the fourth plate body 9 is bonded with the first anti-skid pad 10 , and one side of the sixth plate body 15 is bonded with the second anti-skid pad 16 . The setting of the second anti-skid pads 16 increases the friction between the fourth plate body 9 and the sixth plate body 15 and the surveying and mapping instrument, enhances the stability of the fixed surveying and mapping instrument, and at the same time plays a protective role for the surveying and mapping instrument, so that the surveying and mapping instrument is protected. The measurement data is more accurate.

In this embodiment, specifically: three support rods 20 are hinged on the lower surface of the bottom plate 1. Through the arrangement of the three support rods 20, the support rods 20 are opened to adapt to an angle according to the usage, and then inserted into the ground to support the device. At the same time, the triangle has the effect of enhancing stability, which makes the device more stable during measurement.

In this embodiment, specifically, one side of the three support rods 20 is fixedly connected with a fixing block 21 , the interior of the three fixing blocks 21 is slidably connected with a latch 22 , and the lower surface of the three fixing blocks 21 is fixedly connected with a For the brush 17, one side of the three support rods 20 is located above the fixed block 21 and is fixedly connected to the limit block 24. Through the setting of the latch 22, after the support rod 20 is inserted into the ground and fixed, the latch 22 is rotated until the bottom does not touch. When reaching the limit block 24, press down on the plug 22, the plug 22 slides in the fixed block 21, and is inserted into the ground to increase the stability of the device. The dirt on the plug is cleaned, which reduces the corrosion of the plug 22 and increases its service life.

In this embodiment, the third anti-skid pads 23 are adhered to the upper surfaces of the three latches 22, and the third anti-skid pads 23 on the latches 22 play an anti-slip effect when the latches 22 are pressed down. , it is better to exert force on the push-down plug 22 .

Working principle or structural principle, when in use, move the device to the designated measurement position, through the setting of three support rods 20, according to the usage, open the support rods 20 to adapt to the angle, and then insert it into the ground to support the device At the same time, the triangle has the effect of enhancing stability, which makes the device more stable during measurement. Through the setting of the plug 22, after the support rod 20 is inserted into the ground and fixed, the plug 22 is rotated until the limit block 24 cannot be touched below. When the plug 22 is pressed down, through the setting of the third anti-skid pad 23 on the plug 22, when the plug 22 is pressed down, it has an anti-slip effect, and it is better to exert force on the pressed plug 22, and the plug 22 slides in the fixed block 21 , inserted into the ground to increase the stability of the device, after use, when the plug 22 is pulled out, the mud on the plug 22 is brushed through the brush 17 to reduce the corrosion of the plug 22 and increase its service life. The first plate body 3 is pulled out from the first chute 2 opened in the bottom plate 1, and is fixed by the second bolt 19. When changing different measurement heights, the second plate body 5 slides in the first plate body 3 through the second slide. Sliding on the groove 4, the first bolt 7 is inserted into the corresponding first threaded through hole 6 for fixing to realize the function of adjusting the angle, and then the surveying and mapping instrument is prevented from being on the third plate body 8, close to the fourth plate body 9, through the The setting of the fifth plate body 11, by rotating the knob 13, drives the threaded rod 12 to rotate on the fifth plate body 11 and pushes the sixth plate body 15, and the threaded rod 12 is set through the bearing 14. The body 15 plays the role of pushing, and will not drive it to rotate, which is convenient and better for the fixed measurement of the surveying and mapping instrument.

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the present invention , alternatives and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
