DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example: Refer to Figure 1 The utility model provides a municipal engineering road measuring device, including a support base 1, the outer surface of the support base 1 is rotatably connected to a support device 5, the top of the support base 1 is rotatably connected to a chassis 3 through a fine-tuning mechanism 6 inside a measuring instrument body 2, the inner walls on both sides of the top of the chassis 3 are rotatably connected to a camera 4 through a commonly connected rotating shaft, and a "U"-shaped handle 31 is welded to the top of the camera 4, and the "U"-shaped handle 31 serves to facilitate the operator to carry it.

[0032] Reference Figure 3 The fine-tuning mechanism 6 includes a shaft seat 61 and two shaft ends 66. The two shaft ends 66 extend in two directions to form an "L" shape. A movable shaft 65 is rotatably connected between the two shaft ends 66. One end of the shaft seat 61 is fixedly connected to a shaft sleeve 64. The middle outer surface of the movable shaft 65 is sleeved with the inner surface of the shaft sleeve 64. One end of one of the shaft ends 66 is fixedly connected to a clutch plate 69. A spring 70 is fixedly connected between the clutch plate 69 and the support seat 1. The spring 70 provides an upward force for the two shaft ends 66 to keep the two shaft ends 66 horizontal. When pressure is applied downward to the clutch plate 69, the two shaft ends 66 can rotate.

[0033] Reference Figure 1 A rectangular groove is provided at the top of the measuring instrument body 2, and the lower part of the clutch plate 69 movably extends into the measuring instrument body 2 through the rectangular groove.

[0034] Reference Figure 3The upper outer surfaces of the two shaft ends 66 are interspersed with a worm 67, and the outer surface of the worm 67 is meshed with a worm wheel 62. The top of the shaft seat 61 is rotatably connected to the worm wheel 62. The rotating shaft 60 is located inside the worm wheel 62. The rotating shaft 60 is fixedly connected to the worm wheel 62. The support shaft 63 is fixedly connected to the rotating shaft 60. The bottom end of the support shaft 63 is fixedly connected to the bottom end of the chassis 3. One end of the worm 67 is fixedly connected to a fine-tuning bolt 68. By rotating the fine-tuning bolt 68, the worm 67 drives the worm wheel 62 to rotate, thereby driving the support shaft 63 and the chassis 3 to rotate. If pressure is applied downward to the clutch plate 69, the worm 67 meshed with the worm wheel 62 will be disconnected.

[0035] Reference Figure 2 The supporting device 5 includes three first telescopic rods 51, and the three first telescopic rods 51 are distributed in a circular array. The inner surfaces of the three first telescopic rods 51 are slidably sleeved with the second telescopic rods 52, and the outer surfaces of the second telescopic rods 52 are slidably fitted with the inner surfaces of the first telescopic rods 51. The bottom end of the supporting seat 1 is fixedly connected with 54, and the outer surface of the centering rod 54 located on the same horizontal line as the center point of the supporting seat 1 is fitted with a ring 55, and the outer surface of the slidably fitted ring 55 is rotatably connected to three limit rods 56, and the other ends of the three limit rods 56 respectively rotatably connect the three first telescopic rods 51 through the rotating shaft, thereby providing a centering axis for the three first telescopic rods 51 and providing a limiting effect of a certain angle for the three first telescopic rods 51.

[0036] Reference Figure 2 and Figure 4 A buckle ring 57 is fixedly sleeved on the outer surface of the first telescopic rod 51, and a slot 570 is provided on the outer surface of the buckle ring 57. A fixed shaft 571 is provided in the buckle ring 57. The fixed shaft 571 is rotatably connected to the upper and lower inner walls of the slot 570. A pressing groove 53 is provided on the outer surface of the first telescopic rod 51. The eccentrically rotating fixed shaft 571 extends the end face of the fixed shaft 571 with a larger radius value from the slot 570 to the inside through rotation. A fixing pin 572 is inserted and connected to the inner wall of one side of the buckle ring 57. Both sides of the fixing pin 572 are arc-shaped. The fixed shaft 571 is rotated to abut against one end of the fixing pin 572, so that the abutted fixing pin 572 is engaged and fixed to the second telescopic rod 52.

[0037] Working principle: When it is necessary to measure on the road, the measuring device is placed on the road surface through the support device 5, the elevation and depression angles are adjusted by rotating the camera 4 up and down, and the horizontal rotation angle is adjusted through the fine-tuning mechanism 6. The operator holds the fine-tuning bolt 68 and rotates the fine-tuning bolt 68 to drive the worm 67 to rotate. The rotating worm 67 drives the worm wheel 62 to rotate through the rotating shaft 60, so that the support shaft 63 fixedly connected to the rotating shaft 60 rotates, and then drives the chassis 3 to rotate more slowly. The slowly rotating chassis 3 drives the camera 4 to perform fine rotation adjustment of the horizontal viewing angle;

[0038] When there is no need to fine-tune the camera 4, the operator presses the clutch plate 69 downward, and the pressed clutch plate 69 drives the shaft end 66 to rotate through the shaft sleeve 64 at one end of the shaft seat 61 through the spring 70. The two rotating shaft ends 66 then drive the worm 67 to rotate, so that the worm 67 is disconnected from the worm wheel 62. At this time, the operator can quickly rotate the chassis 3 to achieve the purpose of controlling the rotation speed.

[0039] When the support device 5 needs to be extended or retracted, the operator can toggle the fixed shaft 571 in the buckle 57 to rotate it. The rotating fixed shaft 571, through the eccentric design, turns the end with a smaller radius value to the fixed pin 572, so that one end of the fixed shaft 571 is separated from the fixed pin 572. At this time, the fixed pin 572 is retracted toward the fixed shaft 571, so that the fixed pin 572 is separated from one end of the second telescopic rod 52. The second telescopic rod 52 without friction slides out from the inner wall of the first telescopic rod 51, thereby achieving the purpose of increasing the support height. When it needs to be fixed, toggle again The fixed shaft 571 makes the end of the fixed shaft 571 with a larger radius value press against the arc surface end of the fixing pin 572, so that the fixing pin 572 applies pressure to the outer surface of one side of the second telescopic rod 52, and the second telescopic rod 52 is pressed and fixed between the inner walls of the first telescopic rod 51 through a large friction force, thereby achieving the purpose of fixing the second telescopic rod 52. The centering rod 54 located at the center is rotatably connected to the three first telescopic rods 51 through the limiting rod 56 on the surface of the ring 55, and provides a limiting function for the three first telescopic rods 51 during the unfolding process of the three first telescopic rods 51.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
