[0002] Construction projects refer to the general term for various types of buildings and engineering facilities that provide the material and technical basis for human life and production. Construction projects are organized, purposeful, large-scale economic activities of human beings. According to their natural attributes, they can be divided into three categories: architectural engineering, civil engineering, and mechanical and electrical engineering. They are engineering projects that form comprehensive production capacity or exert engineering benefits in the process of fixed asset reproduction. During the construction of construction projects, it is necessary to measure the size and angles of the building.

When the angle needs to be measured, the rotating rod can be rotated around the central axis to not only open the rotating rod from the storage slot, but also the meshing part can be engaged with the toothed guide rail to achieve the purpose of measuring the angle, so that the device has the characteristics of being easy to measure the length and angle of the object to be measured, and easy to store and carry.

[0004] However, although the above patent can achieve the function of measuring angles, the setting of the angle disk makes it impossible for the angles of the level ruler and the rotating rod to contact the inner angles of the object to be measured. When in use, the angle of the object can only be measured from the outside or end. It has certain limitations when used and is not practical. In view of this, the present application proposes a multifunctional measuring device for construction projects. Utility Model Content

[0022] See also Figure 1-4 In this embodiment, a multifunctional measuring device for construction engineering includes a reference frame 1, and a measuring adjustment mechanism is arranged inside the reference frame 1.

[0023] In this embodiment, the measurement and adjustment mechanism includes a rotating shaft 3 rotatably connected to the inside of the reference frame 1, and the outer side of the rotating shaft 3 is fixedly connected to the rotating block 2. The reference frame 1 is a frame-type structure with a U-shaped cross-section, which makes it convenient for the reference frame 1 to accommodate the rotating block 2. The end of the rotating block 2 away from the rotating shaft 3 is fixedly connected to a toggle plate 201, which makes it convenient to adjust the inclination angle of the reference frame 1 and the rotating block 2 by operating the toggle plate 201.

[0024] Among them, the internal rotation of the rotating block 2 is connected to the winding roller 4, and the outer side of the winding roller 4 is wound with a reference cloth 5 fixedly connected to the reference frame 1. The winding roller 4 is a conical structure, and the reference cloth 5 is a fan-shaped structure, which is convenient for improving the rotating winding roller 4 to achieve the winding of the reference cloth 5 and maintain the winding effect; the reference cloth 5 can be printed with angle measurement scales, so that the user can check the rotation angle of the rotating block 2 relative to the reference frame 1.

[0025] Among them, a receiving and releasing opening is opened on the side of the rotating block 2 close to the reference frame 1, and the internal rotation of the rotating block 2 is connected to a guide pressure roller 6 located in the receiving and releasing opening. When convenient, the reference cloth 5 can move inside and outside the rotating block 2 using the set receiving and releasing opening, and the set guide pressure roller 6 can reduce the friction damage of the rotating block 2 to the reference cloth 5.

[0026] In this embodiment, a curling assembly is provided inside the rotating block 2 for realizing the reset rotation of the winding roller 4; the curling assembly includes a rotating rod 7 fixedly connected to the two ends of the winding roller 4, and a rotating wheel 8 is fixedly connected to the side of the rotating rod 7 away from the winding roller 4. A curling spring piece 9 located on the outside of the rotating wheel 8 is installed inside the rotating block 2, so that the curling spring piece 9 can drive the rotating rod 7 and the winding roller 4 to rotate using the rotating wheel 8 in the absence of external force, thereby achieving the function of automatically winding the reference cloth 5.

[0027] Among them, a ratchet 10 is fixedly connected to the top of the rotating shaft 3, a protective frame 11 is fixedly connected to the top of the reference frame 1, a pull rod 13 is slidably connected inside the protective frame 11, and a locking claw 14 is fixedly connected to the end of the pull rod 13 close to the ratchet 10, so that the ratchet 10 can be clamped with the locking claw 14, and a pushing component for pushing the pull rod 13 is arranged inside the protective frame 11.

[0028] Among them, the push-pull assembly includes a mounting sleeve 12 fixedly connected to the outside of the protective frame 11 and slidably connected to the pull rod 13, a limiting ring 15 fixedly connected to the outside of the pull rod 13, and an extrusion spring 16 fixedly connected to the limiting ring 15 and the mounting sleeve 12 is sleeved on the outside of the pull rod 13, so that the limiting ring 15 drives the pull rod 13 to move toward the ratchet 10 under the push of the extrusion spring 16, so that the locking claw 14 engages the ratchet 10.

[0029] The beneficial effects of the above embodiments are:

[0030] The multifunctional measuring device for construction projects can set scale lines on the end face of the reference frame 1 to measure the length of the object; and the inclination angle of the reference frame 1 and the rotating block 2 can be adjusted by operating the toggle plate 201. During this process, the reference cloth 5 can be gradually unfolded as the inclination angle between the reference frame 1 and the rotating block 2 increases, so that the user can measure the angle of the object through the angle scale printed on the reference cloth 5; since there is no obstruction at the corner between the reference frame 1 and the rotating block 2, the device can measure the angle of the object from any position, which helps to improve the practicality and applicability of the device; and after the angle measurement is completed, the setting of the curling spring piece 9 can be used to realize the automatic winding of the reference cloth 5, and the rotating block 2 is brought closer to the reference frame 1, so that the set reference frame 1 can accommodate the rotating block 2, so as to achieve a folding effect, reduce the size of the device, and make the device easy to carry.

[0031] The working principle of the above embodiment is:

[0032] When the multifunctional measuring device for construction engineering is used, the length of an object can be measured through the scale lines set on the end surface of the reference frame 1; when measuring an angle, the inclination angle between the reference frame 1 and the rotating block 2 can be adjusted by operating the toggle plate 201, and as the inclination angle between the reference frame 1 and the rotating block 2 increases, the reference cloth 5 will gradually unfold, so that the user can conveniently measure the angle of the object through the angle scale printed on the reference cloth 5;

[0033] In this process, the rotating shaft 3 and the ratchet 10 can rotate with the rotating block 2, and when the rotating block 2 does not rotate, the extrusion spring 16 can push the limit ring 15 and the pull rod 13 to move toward the ratchet 10, so that the stop claw 14 can engage the ratchet 10, so as to limit the reference frame 1 and the rotating block 2 from rotating freely, so as to facilitate the user to read the angle value of the object according to the angle scale on the reference cloth 5;

[0034] When the angle measurement is completed, the pull rod 13 can be pulled to disengage the locking claw 14 from the ratchet 10. At this time, the curling spring piece 9 can use the rotating wheel 8 to drive the rotating rod 7 and the winding roller 4 to rotate, thereby achieving the function of automatically winding up the reference cloth 5, and making the rotating block 2 automatically move closer to the reference frame 1 until the rotating block 2 is folded to the inside of the reference frame 1, thereby reducing the size of the device and making it easy to carry.
