[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0030] Example 1

[0031] Please refer to Figure 1-7 As shown, a measuring device for engineering surveying includes a mounting frame 1, a protective mechanism 2 and an adjusting mechanism 3. A laser rangefinder 102 is installed on the inner side of the mounting frame 1 through the adjusting mechanism 3. The protective mechanism 2 is connected to the left side of the laser rangefinder 102. A laser probe 103 is fixedly installed on the left side of the laser rangefinder 102. The laser probe 103 is located on the inner side of the protective mechanism 2. A locking mechanism 4 is installed on the outer side of the mounting frame 1. A bracket 101 is fixedly connected to the lower end of the mounting frame 1. The protective mechanism 2 includes a rotating ring 202, a connecting rod 204 and a rotating protective sleeve 206. The protective sleeve 206 is sleeved on the outer side of the laser probe 103. The left end of the protective sleeve 206 is rotatably connected to a plurality of groups of protective plates 205. The rotating ring 202 and the protective plates 205 are hinged through the connecting rod 204.

[0032] In this solution, the laser rangefinder 102 is electrically connected to an external power supply. When in use, the device is carried to an area to be measured and supported by the bracket 101. At the same time, the angle of the laser rangefinder 102 is adjusted by the adjustment mechanism 3, and then the angle of the laser rangefinder 102 is locked by the locking mechanism 4. At this time, the rotating ring 202 is turned to drive the connecting rod 204 to rotate the multiple sets of protective plates 205, thereby opening the left end of the protective cover 206, so that the laser beam of the laser probe 103 can be irradiated to the target to be measured. When the measurement is completed, the rotating ring 202 can be reversed to rotate and close the multiple sets of protective plates 205, and the left end opening of the protective cover 206 is blocked, thereby forming a closed space for the laser probe 103, preventing impurities such as flying sand and dust from entering the laser probe 103, and effectively protecting it.

[0033] Example 2

[0034] Please refer to Figure 2-5 As shown, the protection mechanism 2 further includes a fixed sleeve 201 , which is fixedly connected to the left side of the laser rangefinder 102 , and a rotating ring 202 is rotatably connected to the inside of the fixed sleeve 201 .

[0035] A plurality of limiting rods 207 are fixedly connected to the inner left end of the fixing sleeve 201 , and a plurality of limiting grooves 209 are provided inside the rotating ring 202 . The rotating ring 202 is slidably connected to the limiting rods 207 via the limiting grooves 209 .

[0036] A moving groove 210 is formed at the left end of the outer surface of the fixed sleeve 201 . A lever 208 is fixedly connected to the outer surface of the rotating ring 202 . The lever 208 is slidably connected to the inside of the moving groove 210 . The upper end of the lever 208 extends to the outside of the moving groove 210 .

[0037] An articulated seat 203 is fixedly connected to the inner side of the rotating ring 202 , and the connecting rod 204 is hinged to the rotating ring 202 via the articulated seat 203 .

[0038] In this solution, when measuring, the lever 208 is slid clockwise to the end of the movable slot 210, thereby driving the rotating ring 202 to rotate inside the fixed sleeve 201, and then driving the connecting rod 204 to drive the multiple sets of protective plates 205 to rotate.

[0039] Example 3

[0040] Please refer to Figure 6 As shown, the adjustment mechanism 3 includes two groups of rotating shafts 301, one end of the two groups of rotating shafts 301 is rotatably connected to the inner side of the mounting frame 1 through a bearing, and the other end of the two groups of rotating shafts 301 is fixedly connected to the outer side of the laser rangefinder 102, and the outer side of one group of rotating shafts 301 is fixedly connected with an adjusting gear 302.

[0041] The adjustment mechanism 3 also includes an adjustment rod 303, which is rotatably connected to the inside of the mounting frame 1. One end of the adjustment rod 303 extends to the inside of the mounting frame 1 and is fixedly connected to a rotating gear 304 that meshes with the adjustment gear 302. The other end of the adjustment rod 303 extends to the outside of the mounting frame 1 and is fixedly connected to an adjustment handle 305.

[0042] In this solution, when the angle of the laser rangefinder 102 needs to be adjusted, the adjusting handle 305 is rotated to drive the rotating gear 304 to rotate, so that the adjusting gear 302 drives the rotating shaft 301 to rotate, thereby increasing or decreasing the angle of the laser rangefinder 102 for easy measurement.

[0043] Example 4

[0044] Please refer to Figure 7 As shown, the locking mechanism 4 includes a pull rod 401, which is slidably connected to the inside of the mounting frame 1, one end of the pull rod 401 extends to the inner side of the mounting frame 1 and is fixedly connected to a locking tooth plate 402 meshing with the adjusting gear 302, and the other end of the pull rod 401 extends to the outside of the mounting frame 1.

[0045] A locking spring 404 is sleeved on the outer side of the pull rod 401 , and one end of the locking spring 404 abuts against the locking tooth plate 402 and the mounting frame 1 respectively. A limiting block 403 is fixedly connected to the middle part of the outer side of the pull rod 401 .

[0046] After the angle of the laser rangefinder 102 is adjusted, the locking tooth plate 402 is pushed to engage with the adjusting gear 302 by the locking spring 404, thereby locking the adjusting gear 302 to prevent it from rotating, thereby fixing the angle of the laser rangefinder 102. When the angle of the laser rangefinder 102 needs to be adjusted, the pull rod 401 is pulled outward to move the limit block 403 out of the outside of the mounting frame 1. At this time, the pull rod 401 is rotated to make the limit block 403 abut against the outer surface of the mounting frame 1, and the position of the locking tooth plate 402 is fixed, thereby releasing the locking state of the locking tooth plate 402 on the adjusting gear 302. After adjustment, the pull rod 401 is rotated to reset the limit block 403.

[0047] The working principle and use process of the utility model are as follows: when in use, the device is carried to the area to be measured, and supported by the bracket 101, and the lever 208 is slid clockwise to drive the rotating ring 202 to rotate inside the fixed sleeve 201, thereby driving the connecting rod 204 to drive the multiple sets of protective plates 205 to rotate and open the left end of the protective sleeve 206. When the angle of the laser rangefinder 102 needs to be adjusted, the pull rod 401 is pulled outward to release the locking state of the locking tooth plate 402 on the adjustment gear 302. At this time, the adjustment handle 305 is rotated to drive the rotating gear 304 to rotate, thereby increasing or decreasing the angle of the laser rangefinder 102. The laser beam of the laser probe 103 can be irradiated to the target to be measured. After adjustment, the pull rod 401 is rotated to reset the limit block 403, and the locking spring 404 pushes the locking gear plate 402 to engage with the adjusting gear 302, thereby locking the adjusting gear 302, and then fixing the angle of the laser rangefinder 102. After the measurement, the rotating ring 202 can be reversed to rotate and close the multiple sets of protective plates 205, and the left end opening of the protective cover 206 is blocked, thereby forming a closed space for the laser probe 103, preventing impurities such as flying sand and dust from entering the laser probe 103, and effectively protecting it.
