[0023] The following is combined with Figure 1-3 The utility model is further described.

[0024] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: an error calibration device for construction project quality supervision.

[0025] The specific technical solution includes a mounting support rod 1 and a steering assembly 5. The mounting support rod 1 is provided with a mounting groove 2 on its front side. The mounting groove 2 is provided with an arc-shaped alignment groove 3 inside. The arc-shaped alignment groove 3 is 90 degrees and is arranged at the lower left of the inner wall of the mounting groove 2. Two positioning holes 4 are provided inside the mounting groove 2. The two positioning holes 4 are distributed at 90 degrees, and the two are respectively located directly above the inner wall of the mounting groove 2 and on the right side of the inner wall;

[0026] The steering assembly 5 is arranged inside the mounting groove 2, and is used to change the orientation of the measuring mechanism. The steering assembly 5 includes a rotating column 501 rotating inside the mounting groove 2, and an alignment block 502 is fixed on the outer surface of the rotating column 501, and the alignment block 502 is slidably installed inside the arc-shaped alignment groove 3. An inner groove 503 is opened inside the rotating column 501, and a spring 504 is fixed inside the inner groove 503. A slide plate 505 is slidably installed inside the inner groove 503, and a positioning column 506 is fixed above the slide plate 505. One end of the positioning column 506 passes through and extends to the outside of the rotating column 501. When the alignment block 502 slides to the two ends of the inner wall of the arc-shaped alignment groove 3, the positioning column 506 corresponds to the two positioning holes 4 respectively, and a power-assisting plate 507 is fixed on the front of the rotating column 501.

[0027] A measuring assembly 6 is fixed at one end of the rotating column 501. The measuring assembly 6 includes a semicircular shell 601 fixed at one end of the rotating column 501. An angle scale line 602 is provided on the inner surface of the semicircular shell 601. A gravity hammer 603 is fixed inside the semicircular shell 601 through a traction rope. The gravity hammer 603 is always kept vertically downward by the action of gravity. Figure 1 The device is placed on the floor of a building in the unfolded state. If the floor is uneven, the error of the floor balance can be measured according to the direction between the gravity hammer 603 and the angle scale line 602. The device can be calibrated according to the measurement result for use on the wall of a building.

[0028] Both ends of the mounting support rod 1 are provided with connecting grooves 7, and positioning screws 8 are threadedly arranged above the two connecting grooves 7. Telescopic components 9 are rotatably installed inside the two connecting grooves 7. The telescopic components 9 are used to change the occupied volume of the device. The telescopic components 9 include a connecting column 901 that rotates inside the connecting groove 7. A threaded groove is arranged above one end of the connecting column 901 that rotates inside the connecting groove 7. When the connecting column 901 is rotated to the state where the two ends of the mounting support rod 1 are unfolded, the positioning screw 8 is screwed into the threaded groove to fix the position of the connecting column 901. A storage groove 902 is arranged inside the connecting column 901, and an internal threaded tube 903 is rotatably installed at one end of the connecting column 901. A telescopic threaded rod 904 is slidably arranged inside the storage groove 902, and the internal threaded tube 903 is threadedly sleeved on the outside of the telescopic threaded rod 904.

[0029] When the device is carried, the telescopic threaded rod 904 is gradually slid into the storage groove 902 by rotating the internal threaded tube 903, and the positioning screw 8 is screwed out of the threaded groove to contact the limit of the connecting column 901, and the two connecting columns 901 are rotated to relative directions to reduce the volume of the device.

[0030] A leg 10 is fixed to one end of the telescopic threaded rod 904, and a handle bar 11 is fixed to one side of the leg 10. A Velcro connecting belt 12 is provided on the outside of the handle bar 11. Since there are two groups of telescopic components 9, two legs 10 are also provided accordingly, but the Velcro connecting belt 12 is only provided on one of the handle bars 11. When the connecting column 901 is rotated to the opposite direction, the two handle bars 11 are wrapped together with the Velcro connecting belt 12, so that the device can be folded, and the device can be carried by directly holding the handle bar 11.

[0031] In order for those skilled in the art to fully understand the technical solution, this application makes the following overall summary:

[0032] When in use, pinch the assisting piece 507 and the slide plate 505, apply force to make the slide plate 505 slide down, and the slide plate 505 squeezes the spring 504 while driving the positioning column 506 into the inner groove 503, contacting the limit of the rotating column 501, and rotating the rotating column 501 ninety degrees. The rotating column 501 drives the measuring component 6 to change direction. When the alignment block 502 is against one end of the arc alignment groove 3 and cannot rotate, the positioning column 506 will correspond to the positioning hole 4, release the slide plate 505, and the spring 504 pushes the positioning column 506 to fit into the positioning hole 4 to fix the direction of the column measuring component 6. The two legs 10 of the device are attached to the wall. The direction pointed by the gravity hammer 603 in the measuring component 6 and the pointing scale line can be easily measured to see whether the vertical surface meets the standard, which helps to reduce the limitations of the use of the device.
