[0023] Embodiment

[0024] As Figures 1-5 shown, a kind of construction engineering construction foundation pit measuring device, including support and laser range finder 2, support includes fixed sleeve rod 1, movable rod 11 being slidably arranged in one end of fixed sleeve rod 1, and fixed mechanism being arranged between fixed sleeve rod 1 and movable rod 11, movable rod 11 can slide in fixed sleeve rod 1, to adjust the overall length of support, the length of support after adjustment can be quickly fixed using fixed mechanism.

[0025] As Figures 1-2 shown, laser range finder 2 is installed in one end of support, fixed sleeve rod 1 and the bottom surface of laser range finder 2 are located in the same horizontal plane, when using, support can be placed horizontally on the top of foundation pit, so that the bottom surface of laser range finder 2 can be flush with the top of foundation pit, then by adjusting the length of support, the laser range finder 2 at one end of movable rod 11 can be suspended in the top of foundation pit, so that the laser red line of laser range finder 2 can avoid the earth of foundation pit side wall, then using laser range finder 2 can quickly measure the depth of foundation pit.

[0026] As Figures 1-2 shown, movable rod 11 is provided with a plurality of finger holes 12 at one end close to laser range finder 2, and a plurality of fixed holes 13 are provided at the other end of movable rod 11, and staff can put fingers into finger holes 12 to slide movable rod 11, to facilitate adjusting the length of support.

[0027] As Figures 2-5As shown, the fixed sleeve rod 1 is fixedly provided with a handle 3 on the outside, and a spring 31 is fixedly provided on the inside of the handle 3. The fixing mechanism comprises a pull plate 32 fixedly provided at one end of the spring 31, and a fixing rod 33 fixedly provided at one side of the pull plate 32. One end of the fixing rod 33 penetrates through the fixed sleeve rod 1 and is inserted into the fixing hole 13 in a matched mode. The pull plate 32 can connect the spring 31 and the fixing rod 33. Under the elastic force of the spring 31, the fixing rod 33 in the fixed sleeve rod 1 is inserted into the corresponding fixing hole 13, so as to fix the length of the adjusted support.

[0028] When it is necessary to adjust the length of the support, the staff can hold the handle 3 and then pull the pull plate 32 away from the fixed sleeve rod 1 by fingers. At this time, the fixing rod 33 will slowly move to the outside of the fixed sleeve rod 1 and be separated from the fixing hole 13. Then, the staff can put the fingers of the other hand into the finger hole 12 to slide the movable rod 11, so as to adjust the length of the support.

[0029] As shown in Figure 2 , Figure 3 and Figure 5 , the fixed sleeve rod 1 is fixedly provided with a fixing ring 4 at the edge of one end. The fixing ring 4 is fixedly provided with a bellows 41 at one end. The bellows 41 is fixedly provided with a connecting plate 42 between one end and the outer wall of the movable rod 11. The connecting plate 42 is provided with an air guide hole 43 for blowing and cleaning the laser range finder 2 when the bellows 41 is compressed. The fixing ring 4 can connect the fixed sleeve rod 1 and the bellows 41. The connecting plate 42 can connect the bellows 41 and the movable rod 11.

[0030] When the movable rod 11 slides to the outside of the fixed sleeve rod 1, the bellows 41 will be stretched. At this time, the external air will enter the inside of the bellows 41 and the fixing ring 4 through the air guide hole 43. When the movable rod 11 slides to the inside of the fixed sleeve rod 1, the bellows 41 will be compressed to blow and clean the screen of the laser range finder 2 through the air guide hole 43. This reduces the dust and other foreign matters at the screen of the laser range finder 2, and facilitates the staff to view the measurement data at the screen of the laser range finder 2.

[0031] As shown in Figure 2 , Figure 3 and Figure 5 , the fixing ring 4 is provided with an observation hole 44 on the outside for discharging the dust and other foreign matters in the bellows 41 and the fixing ring 4. The staff can view the wear and use of the internal movable rod 11 through the observation hole 44, or insert an external air gun into the observation hole 44 to blow and clean the bellows 41 and the fixing ring 4.

[0032] As shown in Figure 2 , Figure 3 and Figure 5As shown, the cover plate 45 is detachably arranged in the observation hole 44, one side of the cover plate 45 is fixedly provided with a handle 46 outside the fixed ring 4, the cover plate 45 can be detachably arranged in the observation hole 44 through a threaded connection or the like, and a worker can rotate the cover plate 45 through the handle 46, and the cover plate 45 can block the observation hole 44.

[0033] It should be noted that the building engineering construction foundation pit measuring device, in use, first places the support horizontally on the top of the foundation pit, so that the bottom surface of the laser range finder 2 is flush with the top of the foundation pit, then adjusts the length of the support, so that the laser range finder 2 at one end of the movable rod 11 can be suspended at the top of the foundation pit, so that the laser red line of the laser range finder 2 can avoid the earth on the side wall of the foundation pit, and then the laser range finder 2 can be used to quickly measure the depth of the building engineering construction foundation pit.

[0034] When the length of the support needs to be adjusted, the worker can hold the handle 3 and then pull the pull plate 32 away from the fixed sleeve rod 1 with fingers, at this time, the fixed rod 33 will slowly move to the outside of the fixed sleeve rod 1 and be separated from the fixed hole 13, then the worker can put the fingers of the other hand into the finger hole 12 to slide the movable rod 11, to adjust the overall length of the support, and then release the pull plate 32, at this time, under the elastic force of the spring 31, the fixed rod 33 in the fixed sleeve rod 1 will be inserted into the corresponding fixed hole 13, so as to fix the length of the support after adjustment.

[0035] When the movable rod 11 slides to the inside of the fixed sleeve rod 1, the corrugated pipe 41 will be compressed to blow and clean the screen of the laser range finder 2 through the air guide hole 43, reduce dust and other foreign matters at the screen of the laser range finder 2, and facilitate the worker to view the measurement data at the screen of the laser range finder 2.

[0036] The above-described embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it cannot be understood as a limitation on the patent scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
