[0002] During and after the construction of a building project, in order to ensure construction quality and safety, it is usually necessary to measure the inclination angle of the wall after the building is built. Most of the existing wall inclination detection methods use a ruler or a plumb line to measure the wall inclination. However, the plumb line is easily shaken by external influences, and ruler measurement requires workers to compare the wall and check the ruler data. The operation is cumbersome and prone to errors. In addition, the inclination of the wall is generally small, and it is not convenient to observe with tools such as a ruler, and it is impossible to accurately determine the specific inclination angle.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-6 As shown, a wall surface inclination detection device comprises a housing 1, and a tilt detection device is installed inside the housing 1;

[0023] The shell 1 is square as a whole, and a bubble level 10 is horizontally installed on the upper front side of the shell 1. A first square groove 2 is opened on the left side of the shell 1, and a support column 3 is installed on the upper side of the first square groove 2. The inclination detection equipment includes a rocker arm 4 hinged to the support column 3, a counterweight 5 is fixed to the lower side of the rocker arm 4, and a sector-shaped tooth plate 6 is connected to the right side of the rocker arm 4. A first pinion 7 meshing with the sector-shaped tooth plate 6 is rotatably installed on the lower side of the sector-shaped tooth plate 6, and the angular velocity of the first pinion 7 is greater than the angular velocity of the sector-shaped tooth plate 6. A first dial 8 is installed on the left side of the first pinion 7, and a first pointer 9 connected to the first pinion 7 in transmission is rotatably installed on the left side of the dial.

[0024] When it is necessary to measure the wall, the rear side of the shell 1 is placed in contact with the wall to be tested, and the bubble level 10 is observed to make the shell 1 vertical as a whole. The pendulum 4 is always in a vertical state under the action of the counterweight 5, and a scale corresponding to the inclination angle of the wall is provided on the upper side of the first dial 8. When the wall is tilted in the vertical direction, the pendulum 4 drives the fan-shaped tooth plate 6 to rotate the first pinion 7, and the first pointer 9 cooperates with the first dial 8 to display the corresponding degree of inclination.

[0025] The cooperation between the sector tooth plate 6, the first pinion 7 and the first pointer 9 makes the operation easier when measuring the inclination of the wall. At the same time, the setting of the angular velocity of the first pinion 7 being greater than the angular velocity of the sector tooth plate 6 can make the stroke of the first pointer 9 larger, so that the staff can more conveniently observe the specific inclination angle.

[0026] An annular hollow ring 11 matching the first dial 8 is provided on the upper side of the swing rod 4 .

[0027] The annular hollow ring 11 can prevent the pendulum rod 4 from blocking the first pointer 9 and the first dial 8 during measurement, making it easier to observe the measurement data.

[0028] A handle is installed on the front side of the housing 1, and a rubber sleeve 12 is sleeved on the outer side of the handle.

[0029] The grip is convenient for the staff to hold when measuring the wall, and the rubber sleeve 12 has the functions of anti-slip and sweat absorption.

[0030] A screw rod 13 is vertically rotatably installed at the bottom of the shell 1, a knob 14 is fixed to the lower side of the screw rod 13, the screw rod 13 is threadedly connected to the shell 1, a round rod 15 is vertically fixed to the lower side of the counterweight 5, a round rod sleeve 16 matching the round rod 15 is fixed to the upper side of the screw rod 13, and an inclined surface 17 is provided on the inner side of the round rod sleeve 16.

[0031] When the tilt detection device is needed to measure the wall, the round rod sleeve 16 is located at the lower side of the round rod 15, and the swing arm 4 can swing freely. When the tilt detection device is not needed, the shell 1 is vertically placed, the round rod 15 is aligned with the round rod sleeve 16, and the knob 14 is turned to move the screw 13 upward so that the round rod sleeve 16 on its upper side is sleeved on the outside of the round rod 15.

[0032] The cooperation between the round rod 15 and the round rod sleeve 16 can fix the rocker arm 4 when not in use, protect the fan-shaped toothed plate 6 and the first pinion 7 of the tilt detection device and extend their service life. The inclined surface 17 facilitates the alignment of the round rod 15 and the round rod sleeve 16.

[0033] A second square groove 18 is provided on the right side of the shell 1, and a straight groove 19 is vertically provided on the inner side of the second square groove 18. A vertical detection component is also provided on the right side of the shell 1, and the vertical detection component includes a detection rod 20, one end of the detection rod 20 is hinged to the upper side of the rear portion of the shell 1, and a rack 21 is vertically slidably installed on the upper side of the straight groove 19, a connecting rod 22 is installed between the detection rod 20 and the rack 21, and the two ends of the connecting rod 22 are respectively hinged to the detection rod 20 and the rack 21, and a large gear 23 meshing with the rack 21 is rotatably installed on the rear side of the rack 21, and a second pinion 24 meshing with the large gear 23 and rotatably connected to the shell 1 is installed on the side of the large gear 23, a second dial 25 is installed on the right side of the second pinion 24, and a second pointer 26 transmission-connected to the second pinion 24 is installed on the right side of the second dial 25.

[0034] The number of teeth of the large gear 23 of the vertical detection component is greater than the number of teeth of the second small gear 24. When it is necessary to measure the vertical angle of adjacent walls of the building, the rear side of the shell 1 and the detection rod 20 are respectively abutted against the adjacent walls, and the shell 1 is placed horizontally. When the angle between the adjacent walls is not a right angle, the detection rod 20 deflects the rack 21 through the connecting rod 22, and the rack 21 drives the large gear 23 and the second small gear 24 to rotate, and the second pointer 26 and the second dial 25 can display the angle between the adjacent walls. The detection rod 20 is connected to the shell 1 through a damping shaft. After the vertical detection component is used, the detection rod 20 can be pressed inward for storage.

[0035] The cooperation between the detection rod 20 and the housing 1 enables the tilt detection device to detect the horizontal tilt between adjacent walls, thereby increasing the versatility and flexibility of the tilt detection device.

[0036] A transparent protective shell 27 is installed on the outside of the tilt detection device and the vertical detection component.

[0037] The transparent protective shell 27 can effectively protect the internal parts of the housing 1 while facilitating the observation of the detection data.
