Technical Field

[0001] The utility model relates to the field of building verticality detection, in particular to a construction engineering management detection ruler. Background Art

[0002] When inspecting construction projects, a variety of tests are required, such as: wall horizontality, the degree of the inner and outer angles between walls, the slope of the concrete floor, etc. The readings of the inner and outer angles between adjacent walls are generally checked using an angle measuring ruler.

[0004] However, the existing angle measuring rulers often have inaccurate readings during use, because the rotating ruler is a movable ruler, which is prone to inaccurate measurements due to unstable holding during the measurement process. Utility Model Content

[0013] As a further solution of the utility model: the end surface of the scale plate away from the fixed ruler is formed with scales in the circumferential direction.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By setting a non-reverse-driven rotating mechanism, when the rotating ruler is against the other wall, the rotating ruler cannot rotate in the opposite direction.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 to Figure 4 In an embodiment of the utility model, a construction engineering management inspection ruler comprises a fixed ruler 1 and a rotating ruler 4 rotatably connected to the fixed ruler 1 through a rotating shaft, a receiving groove 2 recessed upward is provided at the bottom end of the fixed ruler 1, and the rotating ruler 4 is located inside the receiving groove 2;

[0023] A reading mechanism is provided below one end of the fixed ruler 1, and the reading mechanism is used to display the readings of the inner angle and the outer angle;

[0024] The other end of the fixed ruler 1 is provided with a rotating mechanism, which is used to drive the rotating ruler 4 to rotate in one direction. The rotating ruler 4 in a force state cannot reversely drive the rotating mechanism to rotate;

[0025] The non-reversible rotating mechanism is used to improve the reading accuracy of the detection ruler.

[0026] In this embodiment: when measuring the inner angle of the wall, the outer angle formed by the fixed ruler 1 and the rotating ruler 4 is used for measurement, and when measuring the outer angle of the wall, the inner angle formed by the fixed ruler 1 and the rotating ruler 4 is used for measurement;

[0027] When measuring, first place the fixed ruler 1 against a wall, and rotate the rotating mechanism. The rotating mechanism drives the rotating ruler 4 to rotate through the rotating shaft until the rotating ruler 4 contacts the other adjacent wall. At this time, the reading of the reading mechanism can be read to know whether the positive angle or negative angle formed by the two adjacent walls is vertical.

[0028] Please refer to Figure 1 and Figure 2 The reading mechanism includes a dial 3 fixedly connected to the bottom of one end of the fixed ruler 1, the center of the dial 3 coincides with the center of the rotating shaft, one end of the rotating shaft is connected to a pointer 6 that fits the end surface of the dial 3, the pointer 6 is rotatably connected to the dial 3, and a circular hole is opened at the center of the dial 3 for the rotating shaft to rotate.

[0029] In this embodiment: when the rotating mechanism rotates, the rotating mechanism drives the rotating shaft to rotate, and the rotating shaft drives the pointer 6 to rotate. The initial position of the pointer 6 points to the 0 degree position of the scale 5. When the rotating ruler 4 contacts a wall, the rotating mechanism cannot rotate, that is, the pointer 6 stops rotating. The reading of the internal angle or the external angle can be known by observing the scale 5 pointed to by the pointer 6.

[0030] Please refer to Figure 1 , Figure 3 and Figure 4 The rotating mechanism includes a worm wheel 7 fixedly connected to the other end of the rotating shaft, a worm 8 is meshed on the outer periphery of the worm wheel 7, a connecting frame 10 for rotationally supporting the worm 8 is integrally formed below the other end of the fixed ruler 1, the worm 8 is rotationally connected to the connecting frame 10, and a transmission shaft 11 penetrating to the outside of the connecting frame 10 is integrally formed at the other end of the worm 8, the transmission shaft 11 is rotationally connected to the connecting frame 10, and a rotating handle 9 is fixedly connected to the other end of the transmission shaft 11.

[0031] In this embodiment: by rotating the rotating handle 9, the rotating handle 9 drives the transmission shaft 11 to rotate synchronously. When the rotating transmission shaft 11 drives the worm 8 to rotate, the spiral portion of the outer wall of the worm 8 squeezes the tooth portion of the worm wheel 7, and the worm wheel 7 rotates. The rotating worm wheel 7 drives the rotating shaft fixedly connected to the rotating ruler 4 to rotate, and the rotating ruler 4 can be driven to rotate by the rotating shaft. Since the transmission of the worm 8 and the worm wheel 7 is a one-way transmission, that is, the worm 8 can drive the worm wheel 7 to rotate, but the worm wheel 7 cannot reversely drive the worm 8 to rotate, thereby avoiding the problem of inaccurate measurement caused by the inability to effectively define the position of the rotating ruler 4 during the measurement process.

[0032] Please refer to Figure 3 and Figure 4 The outer circumference of the rotating handle 9 is formed with a plurality of friction lines at equal intervals, and the friction lines are used to increase the friction between the rotating handle 9 and the hand.

[0033] In this embodiment, the friction pattern reduces the contact area between the hand and the rotating handle 9 , but the force applied to the rotating handle 9 remains unchanged, so the pressure per unit area increases, thereby preventing slipping when the rotating handle 9 is turned.

[0034] Please refer to Figure 2 The end surface of the scale plate 3 away from the fixed ruler 1 is formed with scales 5 in the circumferential direction.

[0035] In this embodiment, the scale 5 divides the 360 ​​degrees on the circumference into equal parts. After the rotating ruler 4 has completed its rotation, the scale 5 pointed to by the pointer 6 can be read.

[0036] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
