A rotating disk 5 is rotatably arranged on the inner side of the fixing ring 4. The rotating disk 5 is fixedly connected to a fixing plate 6. The fixing plate 6 is rotatably connected to a storage rack 7. One end of the storage rack 7 is rotatably connected to an operating handle 9, and one side of the operating handle 9 is fixedly connected to a screw rod 10. An extension tube 11 is slidably arranged on the outside of the screw rod 10, and a suction cup 12 is provided at one end of the extension tube 11.

[0033] The distance measurement adjustment structure 2 can be used by the operator to hold the surveying instrument or fix it on the indoor wall according to the actual needs of the operator. When it is fixed on the wall, the accuracy of the distance measurement can be ensured to avoid errors in the distance measurement results and affect subsequent work.

[0034] In this embodiment, a fixing block 13 is fixed on the outside of the rotating disk 5, and the fixing block 13 is connected to a threaded rod 14 through a thread. One end of the threaded rod 14 is rotatably connected to a clamping plate 15, and the bottom of the clamping plate 15 is flush with the top of the rotating disk 5.

[0035] The position of the clamping plate 15 can be controlled by the threaded rod 14 , and the bottom of the clamping plate 15 is flush with the top of the rotating disk 5 to prevent the clamping plate 15 from deflecting during movement.

[0036] In this embodiment, a limiting ring 16 is fixedly provided on the outside of the fixing ring 4 , and the clamping plate 15 and the limiting ring 16 are engaged and matched.

[0037] Under the action of the threaded rod 14 , the clamping plate 15 is inserted into the limiting groove of the limiting ring 16 to fix the position of the rotating disk 5 , which is convenient for fixing the infrared rangefinder 1 after the ranging angle is adjusted.

[0038] In this embodiment, four threaded holes are formed on the outside of the fixing plate 6 , and two threaded holes are formed on the front and rear parts of the storage rack 7 . The threads of the bolt fasteners 8 are adaptively matched with the threads of the threaded holes of the fixing plate 6 and the storage rack 7 .

[0039] The fixing plate 6 and the storage rack 7 are fixed by bolt fasteners 8 .

[0040] In this embodiment, a ranging support structure 3 is provided on the outside of the storage rack 7. The ranging support structure 3 includes a fixed frame 17 and three plug-in plates 24. The fixed frame 17 and the storage rack 7 are fixedly connected. Three slots 18 are fixedly provided on the outside of the fixed frame 17, and a baffle 19 is fixedly provided on the top of the slot 18. A movable rod 20 is passed through the top of the baffle 19. One end of the three movable rods 20 is fixedly connected through a connecting ring 21, and three limit rods 22 are fixedly provided on the bottom of the connecting ring 21. A spring 23 is provided between the top of the connecting ring 21 and the corresponding baffle 19. A movable frame 25 is rotatably provided on the inner side of the plug-in plate 24. The movable frame 25 is rotatably connected to a handle 26, and a screw rod 27 is fixedly provided on one side of the handle 26. An extension tube 28 is slidably provided on the outside of the screw rod 27, and a suction cup 29 is rotatably provided on one end of the extension tube 28.

[0041] The ranging support structure 3 cooperates with the ranging adjustment structure 2 so that the surveying instrument can be placed on the ground for use, thereby improving the working adaptability of the surveying instrument. At the same time, the setting of the spring 23, the limit rod 22 and the slot 18 makes the installation and disassembly of the plug-in board 24 more convenient.

[0042] In this embodiment, two mounting brackets 30 are fixedly provided on the outside of the infrared rangefinder 1 , three elastic tube clamps 31 are fixedly provided on the inner top of the mounting brackets 30 , and the second extension tube 28 and the elastic tube clamps 31 are adaptively matched.

[0043] In the initial state, the elastic tube clamp 31 cooperates with the extension tube 28 so that the extension tube 28 acts as a handle and will not cause the extension tube 28 to fall. At the same time, in conjunction with the distance measurement adjustment structure 2, the storage rack 7, screw rod 10, extension tube 11, screw rod 27, and extension tube 2 28 can form a tripod shape, further improving the stability of the surveying instrument.

[0044] In this embodiment, the inserting plate 24 is inserted into the inner side of the slot 18 . The slot 18 and the inserting plate 24 are penetrated by the limiting rod 22 . The spring 23 is located at the outer periphery of the corresponding limiting rod 22 .

[0045] The inserting plate 24 is inserted into the slot 18 and is limited by the limiting rod 22 .

[0046] It should be noted that the present invention is a handheld house surveying instrument. When in use, the surveying instrument can be installed at the required place in the house to make it work. In addition, Figure 1 The middle extension tube 11 and the extension tube 28 are both in an extended state;

[0047] In the initial state of the surveying instrument, the first extension tube 11 and the second extension tube 28 are in an unextended state, the inserting plate 24 is not inserted into the slot 18, and the three second extension tubes 28 are clamped in the corresponding elastic clamping tube clips 31 to serve as the handle of the surveying instrument. Based on the initial state of the surveying instrument, the bolt fasteners 8 are removed, the shelf 7 is rotated 90 degrees and then stopped, and the bolt fasteners 8 are then installed to fix the fixing plate 6 and the shelf 7. At this time, the surveying instrument is easy to store and transport.

[0048] When the surveying instrument needs to be fixed on the wall of the room, in the initial state, remove the bolt fastener 8, rotate the shelf 7 ninety degrees and stop, then install the bolt fastener 8 to fix the shelf 7. At this time, the fixing plate 6 and the shelf 7 are vertical. Turn the operating handle 9 with one hand and hold the extension tube 11 with the other hand until the extension tube 11 is extended to the required length and stops. At this time, the suction cup 12 is adsorbed on the corresponding wall to fix the surveying instrument on the wall for measurement. In order to further ensure the stability of the surveying instrument and reduce the burden of the suction cup 12, remove one of the extension tubes 28 from the elastic tube clamp 31, and then adsorb the suction cup 29 on the opposite side below the suction cup 12. After the corresponding position is reached, the angle of the second extension tube 28 is adjusted so that it can adapt to the position of the slot 18. The handle 26 is turned to extend the second extension tube 28 to the predetermined length and then stop. The movable frame 25 is rotated to match the position of the plug plate 24 with the slot 18. The connecting ring 21 is then lifted to pull the limiting rod 22 out of the slot 18. The plug plate 24 is then inserted into the slot 18 at the corresponding position and the connecting ring 21 is released to allow the limiting rod 22 to be inserted into the slot 18 and the plug plate 24 to restrict and fix the plug plate 24. At this time, the storage rack 7, the screw rod 10, the extension tube 11, the screw rod 27, and the extension tube 28 form a tripod shape, which further improves the working stability of the surveying instrument. At this time, the infrared rangefinder 1 can be used to measure the distance indoors.

[0049] When the surveying instrument needs to be placed on the ground for use, in the initial state, the second extension tube 28 is removed from the elastic tube clamp 31, the connecting ring 21 is lifted to pull the limit rod 22 out of the slot 18, and the plug plate 24 is inserted into the slot 18 at the corresponding position. After that, the connecting ring 21 is loosened, so that the limit rod 22 is inserted into the slot 18 and the plug plate 24 to restrict and fix the plug plate 24. Then, the handle 26 is turned to extend the second extension tube 28 to a predetermined length and then stop. Then, the second suction cup 29 is adsorbed on the ground. At this time, the infrared rangefinder 1 can be used to measure the distance indoors.

[0050] In addition, when it is necessary to adjust the ranging angle of the infrared rangefinder 1, the threaded rod 14 is rotated to pull the clamping plate 15 out of the limiting groove of the limiting ring 16, and then the infrared rangefinder 1 is rotated to the required angle and then stopped, and then the clamping plate 15 is inserted into the limiting groove corresponding to the limiting ring 16 through the threaded rod 14. When the operator needs to measure the distance by hand in the initial state of the surveying instrument, he only needs to hold the extension tube 11.
