[0025] like Figure 1 - Figure 5As shown, a fixing device for waterway engineering surveying includes a first support rod 101, a second support rod 102 at the lower end of the first support rod 101, and a third support leg 103 at the end of the first support rod 101 away from the second support rod 102. First fixing rings 104 are symmetrically fixedly connected to both ends of the first support rod 101. Fixing cylinders 105 are fixedly connected to the ends of the second support rod 102 and the third support leg 103 near the first support rod 101. A first serrated annular groove 106 is formed on the inner side of the first fixing ring 104. The inner side of the fixing cylinder 105... A second serrated annular groove 107 is provided on the side. A serrated rod 108 is slidably engaged between the two first fixing rings 104 and the second serrated annular groove 107. The two ends of the serrated rod 108 are respectively fixedly connected to a limit block 109 and a first threaded rod 110. A threaded cylinder 111 is threadedly connected to the outer side of the first threaded rod 110. A measuring device 112 is provided at the end of the third support leg 103 away from the first support rod 101. A measuring rod 113 is provided at the lower end of the measuring device 112. Limit rings 114 are fixedly connected to both ends of the fixing cylinder 105. The limit rings 114 are connected to the first fixing ring 105 and the first threaded rod 108. The fixed ring 104 is rotatably connected. A disassembly assembly is provided between the measuring device 112 and the measuring rod 113. A snap-fit ​​assembly is provided between the measuring device 112 and the third support leg 103. When the operator needs to fix the device, the second support rod 102 and the third support leg 103 are rotated, causing the fixing cylinder 105 to rotate through the second serrated annular groove 107 inside the first fixed ring 104. Then, the serrated rod 108 is inserted into the inner side of the first serrated annular groove 106 and the second serrated annular groove 107. Through the structural design of the first serrated annular groove 106, the second serrated annular groove 107, and the serrated rod 108, thus... After completing the snap-fit, the device is fixed. Then, the threaded cylinder 111 is fitted onto the outside of the first threaded rod 110, so that the first threaded rod 110 and the threaded cylinder 111 are threadedly connected. This prevents the serrated rod 108 from sliding out from the inside of the first serrated annular groove 106 and the second serrated annular groove 107 under non-human-caused circumstances. Then, the measuring device 112 is assembled with the third support leg 103 through the snap-fit ​​assembly. At the same time, the measuring rod 113 is connected to the measuring device 112 by disassembling the assembly. This makes the device foldable and quick to assemble, making it more convenient for workers to carry or move the device.

[0026] The snap-fit ​​assembly includes a connecting plate 401. The measuring device 112 is fixedly connected to the end near the third support leg 103 with the connecting plate 401. The lower end of the connecting plate 401 is fixedly connected to a connecting block 402. The end of the third support leg 103 has a connecting groove 403. The connecting groove 403 and the connecting block 402 are slidably engaged. Moving the connecting plate 401 causes the connecting plate 401 to carry the connecting block 402 along with it, thereby placing the connecting block 402 inside the connecting groove 403, thus completing the rapid assembly of the measuring device 112 and the third support leg 103.

[0027] The lower end of the second support rod 102 is symmetrically fixedly connected to a second fixing ring 502. The inner side of the second fixing ring 502 is rotatably connected to a rotating shaft 504. The outer side of the rotating shaft 504 is fixedly connected to a base 501. The inner side of the base 501 is provided with a fixing screw 503. Rotating the base 501 causes the base 501 to drive the rotating shaft 504 to rotate around the center of the second fixing ring 502. After the rotation is completed, the second support rod 102 is fixed by the fixing screw 503.

[0028] A placement box 601 is provided on the outer side of the first support rod 101. A handle 602 is fixedly connected to the outer side of the placement box 601. After the staff folds the device, the device can be placed in sections into the corresponding slots of the placement box 601, making it more convenient for the staff to carry the device.

[0029] During operation, when the worker needs to fix the device, the second support rod 102 and the third support leg 103 are rotated, causing the fixing cylinder 105 to rotate through the second serrated annular groove 107 inside the first fixing ring 104. Then, the serrated rod 108 is inserted into the inner sides of the first serrated annular groove 106 and the second serrated annular groove 107. The structural design of the first serrated annular groove 106, the second serrated annular groove 107, and the serrated rod 108 completes the engagement, thereby fixing the device. Then, the threaded cylinder 111 is fitted onto the outer side of the first threaded rod 110, so that the first threaded rod 110 and the threaded cylinder 111 are threadedly connected, thereby preventing the serrated rod 108 from slipping out of the first serrated annular groove 104 due to non-human intervention. 06 slides out from the inner side of the second serrated annular groove 107, rotates the base 501, so that the base 501 drives the rotating shaft 504 to rotate around the center of the second fixed ring 502. After the rotation is completed, the second support rod 102 is fixed by the fixing screw 503. Move the connecting plate 401, so that the connecting plate 401 carries the connecting block 402 together and moves it, so that the connecting block 402 is placed inside the connecting groove 403, thereby completing the quick assembly of the measuring device 112 and the third support leg 103. When it is necessary to move the device, the staff can fold the device and place it in sections in the corresponding grooves of the placement box 601, so that it is more convenient for the staff to carry the device. Example

[0030] like Figure 1 - Figure 3 As shown, the disassembly assembly includes a connecting frame 201. The lower end of the measuring device 112 is provided with the connecting frame 201. Both ends of the measuring rod 113 are symmetrically provided with equally spaced serrated grooves 202. Both ends of the connecting frame 201 are slidably connected to moving blocks 203. The ends of the two moving blocks 203 that are close to each other are fixedly connected with equally spaced serrated blocks 204. The equally spaced serrated blocks 204 are slidably engaged with the equally spaced serrated grooves 202. The upper and lower ends of the moving blocks 203 are symmetrically fixedly connected with limiting plates 205. The limiting plates 205 are slidably connected to the connecting frame 201. Next, the two ends of the connecting frame 201 are rotatably connected with second threaded rods 206. The second threaded rods 206 are threadedly connected to the moving block 203. The measuring rod 113 is placed inside the connecting frame 201, and then the second threaded rods 206 are rotated. The second threaded rods 206 are threadedly connected to the moving block 203, and the connecting frame 201 rotates and limits the limiting plate 205, thereby driving the moving block 203 to move laterally. This allows the two moving blocks 203 to drive the equally spaced serrated blocks 204 to slide into the inside of the equally spaced serrated grooves 202, thereby quickly disassembling the measuring rod 113.

[0031] The connecting frame 201 has symmetrically provided limiting grooves 301 at both ends. A fixing block 302 is slidably connected to the inner side of the limiting groove 301. The fixing block 302 is fixedly connected to the limiting plate 205. Since the inner space of the limiting groove 301 is limited, the distance that the limiting plate 205 can move the fixing block 302 is within a certain range, thereby preventing the moving block 203 from sliding out from the inner side of the connecting frame 201, which makes it more convenient to assemble the device later.

[0032] During operation, the measuring rod 113 is placed inside the connecting frame 201, and then the second threaded rod 206 is rotated. The second threaded rod 206 is threadedly connected to the moving block 203, and the connecting frame 201 rotates and limits the limiting plate 205, thereby driving the moving block 203 to move laterally. This allows the two moving blocks 203 to drive the equally spaced serrated blocks 204 to slide into the inside of the equally spaced serrated grooves 202, thus enabling the quick disassembly of the measuring rod 113. Since the inner space of the limiting groove 301 is limited, the distance that the limiting plate 205 drives the fixed block 302 to move is within a certain range, thereby preventing the moving block 203 from sliding out from the inside of the connecting frame 201, which makes subsequent assembly of the device more convenient.

[0033] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
