[0019] The utility model embodiment provides a tool for measuring the vertical flatness of a curved wall, which includes a measuring frame, a measuring ruler, a first bubble meter and a second bubble meter. The measuring frame includes a first frame body arranged vertically and a second frame body arranged horizontally and located at both ends of the first frame body. The second frame body is provided with a guide pulley at one end away from the first frame body to abut against the wall surface of the curved wall. The first frame body is fixedly connected with the first bubble meter arranged horizontally and the second bubble meter arranged vertically. The measuring ruler is also arranged in a ruler groove of the first frame body. Due to the horizontal arrangement of the ruler groove, the measuring ruler can slide in the ruler groove in a horizontal direction. One end of the measuring ruler is provided with a measuring pulley to abut against the wall surface of the curved wall. The other end of the measuring ruler is connected to the measuring frame through an elastic member. Specifically in the utility model embodiment, the elastic member is an elastic rubber band. Further, the measuring ruler is also provided with a scale. Based on the above structure, before use, the operator holds the first frame of the measuring frame and makes the guide pulley at the end of the second frame rest against the curved wall surface. At this time, the measuring pulley at one end of the measuring ruler also rests against the curved wall surface. The first bubble meter and the second bubble meter are zeroed, and the scale on the measuring ruler at any point on the measuring frame is recorded. Then, the operator holds the first frame and makes it slide horizontally along the curved wall surface. During the sliding process, the operator continues to pay attention to the first bubble meter and the second bubble meter to ensure that the measuring ruler does not deviate. As the measuring frame slides continuously, the measuring pulley at the end of the measuring ruler keeps rolling on the curved wall. When the measuring pulley contacts the protrusion on the curved wall, the measuring ruler will slide horizontally along the ruler groove of the measuring frame based on the abutment of the protrusion. It can be found that the sliding of the measuring ruler causes the position between it and the measuring frame to change, and the scale of the selected position on the measuring frame also changes accordingly, thereby informing the operator that there is a protrusion on the curved wall where the measuring ruler passes at this time, so that the operator can mark the relevant position in time and repair it later; further, when the measuring ruler passes the protrusion, the elastic rubber band can give the measuring ruler a force to return to the initial position so that the measuring ruler can find the protrusion in other areas in time; in addition, the setting of the scale can enable the operator to quickly and effectively understand the size of the protrusion, thereby facilitating subsequent repair construction. In this way, the structure of the curved wall vertical flatness measurement tool is simple and reliable, the measurement effect is excellent, and the user experience is good.

DETAILED DESCRIPTION

[0023] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] It should be understood that the terms "front", "rear", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, "front" information may also be referred to as "rear" information, and "rear" information may also be referred to as "front" information without departing from the scope of the present invention.

[0025] like Figure 1 to Figure 2 As shown, an embodiment of the utility model provides a tool for measuring the vertical flatness of a curved wall, which includes a measuring frame 1, a measuring ruler 2, a first bubble meter 3 and a second bubble meter 4. The measuring frame 1 includes a vertically arranged first frame 11 and a horizontally arranged second frame 12 located at both ends of the first frame 11. The second frame 12 is provided with a guide pulley 13 at one end away from the first frame 11 to abut against the curved wall surface. The first frame 11 is fixedly connected with the horizontally arranged first bubble meter 3 and the vertically arranged second bubble meter 4. The measuring ruler 2 is also arranged in the ruler groove 14 of the first frame 11. Due to the horizontal arrangement of the ruler groove 14, the measuring ruler 2 can slide in the ruler groove 14 in the horizontal direction. A measuring pulley 22 is provided at one end of the measuring ruler 2 to abut against the curved wall surface. The other end of the measuring ruler 2 is connected to the measuring frame 1 through an elastic member 5. Specifically, in the embodiment of the utility model, the elastic member 5 is an elastic rubber band. Further, a scale 21 is also provided on the measuring ruler 2.

[0026] Based on the above structure, before use, the operator holds the first frame 11 of the measuring frame 1 and makes the guide pulley 13 at the end of the second frame 12 rest against the curved wall surface. At this time, the measuring pulley 22 at one end of the measuring ruler 2 also rests against the curved wall surface. The first bubble meter 3 and the second bubble meter 4 are zeroed, and the scale 21 on the measuring ruler 2 at any point on the measuring frame 1 is recorded. Then, the first frame 11 is held and made to slide horizontally along the curved wall surface. During the sliding process, the first bubble meter 3 and the second bubble meter 4 are continuously paid attention to to ensure that the measuring ruler 2 does not deviate. As the measuring frame 1 slides continuously, the measuring pulley 22 at the end of the measuring ruler 2 rolls continuously on the curved wall. When the measuring pulley 22 contacts the protrusion on the curved wall, the measuring ruler 2 slides horizontally along the ruler groove 14 of the measuring frame 1 based on the abutment of the protrusion. It can be found that the sliding of the measuring ruler 2 causes the position of the measuring ruler 2 to change with the measuring frame 1, and the scale 21 at the selected position on the measuring frame 1 also changes accordingly, thereby informing the operator that there is a protrusion on the curved wall that the measuring ruler 2 passes through at this time, so that the operator can mark the relevant position in time and repair it later; further, when the measuring ruler 2 passes through the protrusion, the elastic rubber band can give the measuring ruler 2 a force to return to the initial position so that the measuring ruler 2 can find the protrusion in other areas in time; in addition, the setting of the scale 21 can enable the operator to quickly and effectively understand the size of the protrusion, thereby facilitating subsequent repair construction. In this way, the structure of the curved wall vertical flatness measurement tool is simple and reliable, the measurement effect is excellent, and the user experience is good.

[0027] Optionally, in some embodiments of the present application, a plurality of first bubble meters 3 are provided, and each first bubble meter 3 is fixedly connected to the first frame 11. Based on the above structure, the plurality of first bubble meters 3 can effectively monitor the verticality of the first frame 11, reduce measurement errors, and ensure measurement accuracy.

[0028] Similar to the configuration of the first bubble meter 3 , in some embodiments of the present application, a plurality of second bubble meters 4 are provided, and each second bubble meter 4 is fixedly connected to the first frame 11 .

[0029] Optionally, in some embodiments of the present application, a plurality of measuring rulers 2 are provided, one end of each measuring ruler 2 is provided with a measuring pulley 22, and the other end of each measuring ruler 2 is connected to the first frame 11 via an elastic rubber band.

[0030] Furthermore, for the first frame 11 of the present application, a guide rail is provided, on which a guide wheel 24 that can slide along the guide rail is provided, and the measuring ruler 2 is fixedly connected to the guide wheel 24 through an adjustment spring 23. Based on the above structure, before use, both sides of the measuring ruler 2 are connected to the guide wheel 24 through the adjustment spring 23. When in use, one end of the measuring ruler 2 drives the guide wheel 24 to slide along the guide rail and abut against the curved wall under the action of the elastic rubber band, and when a bulge appears on the curved wall against which the measuring ruler 2 abuts, the corresponding bulge can also affect the measuring ruler 2 to drive the guide wheel 24 to slide along the guide rail.

[0031] Furthermore, the measuring ruler 2 of the present application is provided with a reset block 25, and a plurality of sawtooth-shaped slots 26 are provided on the reset block 25. The first frame 11 is provided with a clamping block 15 matching the slots 26. The clamping block 15 is hingedly connected to the first frame 11 and can be clamped into the slots 26 as the measuring ruler 2 slides along the guide rail. Based on the above structure, the operator can confirm the displacement size of the measuring ruler 2 according to the position of the slot 26 where the clamping block 15 is clamped, and then preliminarily confirm the size of the protrusion.

[0032] In addition, in some embodiments of the present application, the first frame 11 and the second frame 12 used to make the measuring frame 1 are both made of square tubes. The square tube has a simple and reliable structure and is easy to split and weld, while effectively ensuring the structural strength of the measuring frame 1.

The measuring frame 1 includes a vertically arranged first frame body 11 and a horizontally arranged second frame body 12 located at both ends of the first frame body 11. The second frame body 12 is provided with a guide pulley 13 at one end away from the first frame body 11 to abut against the curved wall surface. The first frame body 11 is fixedly connected with the horizontally arranged first bubble meter 3 and the vertically arranged second bubble meter 4. The measuring ruler 2 is also arranged in the ruler groove 14 of the first frame body 11. Due to the horizontal arrangement of the ruler groove 14, the measuring ruler 2 can slide in the ruler groove 14 in the horizontal direction. One end of the measuring ruler 2 is provided with a measuring pulley 22 to abut against the curved wall surface. The other end of the measuring ruler 2 is connected to the measuring frame 1 through an elastic member 5.
