Specifically, the tape measure includes a tape measure main body and a measuring assembly 300, the measuring assembly 300 is movably arranged on the tape measure main body; the tape measure main body includes a tape shell 100 and a tape assembly, at least one side wall of the tape shell 100 is arranged as a measuring reference surface 110; the tape assembly is at least partially collected in the inner cavity of the tape shell 100, and the tape in the tape assembly can be extended or retracted relative to the tape shell 100; the measuring assembly 300 includes a measuring dial 310, a first horizontal bubble 320, a laser projecting element, and an annular scale 340, the measuring dial 310 is rotatably connected to the tape shell 100 through a connecting shaft, the first horizontal bubble 320 and the laser projecting element are arranged on the measuring dial 310, the annular scale 340 is arranged on the tape shell 100 corresponding to the measuring dial 310, and the laser emitted by the laser projecting element can be projected on the object to be measured.
[0037] Since the measuring dial 310 is rotationally connected to the ruler case 100 through the connecting column, the first horizontal bubble 320 and the laser projecting element are arranged on the measuring dial 310, and the ruler case 100 is provided with the annular scale 340 corresponding to the measuring dial 310, and the bottom wall of the ruler case 100 serves as the measuring reference surface 110. Therefore, in use, when the tape measure is placed on the surface to be measured through the measuring reference surface 110, the liquid level in the first horizontal bubble 320 can be observed, and if the liquid level is at an angle with the horizontal plane, it indicates that the surface to be measured is inclined, and if the liquid level is parallel to the horizontal plane or the first horizontal bubble 320 is in the middle position, it indicates that the surface to be measured is flat. If it is measured that the surface to be measured is inclined, the inclination angle of the surface to be measured can be obtained through the cooperation of the first horizontal bubble 320 and the annular scale 340. Then, if the inclined surface to be measured needs to be leveled, the surface to be measured is adjusted manually, and then the tape measure is placed on the adjusted surface to be measured, and the liquid level in the first horizontal bubble 320 is observed until the liquid level in the first horizontal bubble 320 is parallel to the horizontal plane or the first horizontal bubble 320 is in the middle position, thereby completing the leveling of the inclined surface to be measured. When a specific angle needs to be drawn, the tape measure is placed on the surface to be measured through the measuring reference surface 110, and then the laser projecting element is started, and according to the required angle, the measuring dial 310 is adjusted with reference to the annular scale 340, so that the laser projected by the laser projecting element is at the target angle with the reference surface, and then the drawing process is completed according to the projected laser. In the whole process, the level and inclination of the surface to be measured, the leveling of the inclined surface to be measured, and the drawing of a specific angle according to the reference surface can be completed by the tape measure without the aid of other measuring equipment, so the operation is simple and the operation efficiency can be improved.
[0038] The connecting column can be arranged on the side of the measuring dial 310 close to the ruler case 100, or directly on the ruler case 100. When the connecting column is arranged on the ruler case 100, the measuring dial 310 is rotationally connected to the first end of the connecting column, and the second segment of the connecting column extends into the inside of the ruler case 100 through the connecting hole in the first side wall 120 of the ruler case 100 and serves as the mounting shaft of the tape measure assembly. The specific arrangement mode is adaptively arranged according to actual needs, which is not limited in the embodiment.
[0039] The specific structure and working principle of the laser projecting element, and the other structures of the tape measure and their working principles are arranged according to the prior art, which will not be described here.
[0040] In the process of marking the specific angle according to the reference surface, in order to ensure that the laser projection member projects the laser, the ruler case 100 or the measurement dial 310 blocks the projection of the laser, and affects the projection effect, in the embodiment, the laser projection member is protruded on the measurement dial 310, and is arranged in a staggered manner with the first horizontal bubble 320; the first horizontal bubble 320 and the laser projection member are arranged on the measurement dial 310 in a relative manner, and in the process of measuring the level and the inclination of the to-be-measured surface and the leveling of the inclined to-be-measured surface, the laser projection can also be performed at the same time, and the working efficiency is further improved through the cooperation of the laser projection member and the first horizontal bubble 320.
[0041] Preferably, at least part of the laser projection member and / or the first horizontal bubble 320 constitutes an auxiliary handle 380 on the measurement dial 310.

[0042] Preferably, the first horizontal bubble 320 is arranged as a first cylindrical horizontal bubble, and when the measurement reference surface 110 is placed on the horizontal surface, the axis of the cylindrical horizontal bubble is parallel to the horizontal surface. Figure 1 and Figure 2 As shown in FIGS. 1, 2 and 3, in this way, the area of the observation liquid surface of the first cylindrical horizontal bubble is as large as possible, so that the operator can observe the first cylindrical horizontal bubble, and the accuracy of the observation result is improved.
[0043] The measurement assembly 300 further comprises an angle pointer 330 arranged on the measurement dial 310 in a corresponding manner with the first cylindrical horizontal bubble. The angle pointer 330 can be arranged in an integral manner on the first cylindrical horizontal bubble, or can be arranged in a separate manner and then fixed on the measurement dial 310. In the two arrangement manners, the extension direction of the angle pointer 330 is parallel to the axis of the first cylindrical horizontal bubble.

In the process of using the tape measure, the level and the inclination of the to-be-measured surface and the leveling of the inclined to-be-measured surface can be determined by observing the two liquid surfaces in the first annular horizontal bubble. For example, when the two liquid surfaces in the first annular horizontal bubble are in the same horizontal plane, it indicates that the to-be-measured surface is a plane, and when there is a height difference between the two liquid surfaces in the first annular horizontal bubble, it indicates that the to-be-measured surface is an inclined surface. The inclined surface is adjusted so that the two liquid surfaces are in the same horizontal plane, and then the leveling process of the inclined to-be-measured surface is completed.

The specific arrangement mode can be adaptively selected according to actual needs. In the present embodiment, the second level bubble 350 is arranged on the top wall 130.
[0047] The second level bubble 350 can be arranged as a second cylindrical level bubble, and the axis of the second cylindrical level bubble is perpendicular to the axis of the first level bubble 320; or the second level bubble 350 can be arranged as a second ring-shaped level bubble. The specific arrangement mode can be adaptively selected according to actual needs. In the present embodiment, the second level bubble 350 is arranged as a second cylindrical level bubble.
[0048] Preferably, the measuring assembly 300 further comprises a compass 360, which is arranged in the middle of the measuring dial 310. The middle of the measuring dial 310 is provided with a circular accommodating cavity, the center of which is arranged concentrically with the center of the measuring dial 310, and the compass 360 is arranged in the circular accommodating cavity. The tape measure can also achieve the effect of indicating the direction by means of the compass 360. The opening end of the circular accommodating cavity is provided with a transparent cover plate to avoid the influence of external factors on the compass 360 and to avoid damage to the compass 360 caused by external impurities.
[0049] Preferably, the first level bubble 320 and the laser projecting element are arranged opposite to each other on both sides of the compass 360. In this way, when the compass 360 indicates the direction, the first level bubble 320 and the laser projecting element can serve as the reference for direction indication, for example, the first level bubble 320 indicates north, and the laser projecting element indicates south.
