[0036] In combination Figure 1 And Figure 2 As shown in the drawings, the present embodiment provides a tape measure, which can simplify the operation process when measuring the horizontal and inclination angle, leveling the inclined surface to be measured, and distinguishing the direction in special environment, so as to improve the operation efficiency. Specifically, the tape measure includes a tape measure main body, a compass 360, and a measuring assembly 300; the tape measure main body includes a tape measure shell 100 and a tape assembly, the tape assembly is at least partially collected in the inner cavity of the tape measure shell 100, and the tape of the tape assembly can be extended or retracted relative to the tape measure shell 100; the compass 360 is fixedly arranged on the side wall of the tape measure shell 100; the measuring assembly 300 includes a measuring dial 310, a first level bubble 320, and an annular scale 340, the measuring dial 310 is rotationally connected to the side wall of the tape measure shell 100 through a connecting shaft, and the compass 360 is arranged in the middle of the measuring dial 310, the first level bubble 320 is arranged on the measuring dial 310, and the annular scale 340 is arranged on the tape measure shell 100; the first level bubble 320 at least partially serves as an auxiliary handle 380 of the measuring dial 310.
[0037] Since the measuring dial 310 is rotationally connected to the ruler case 100 through the connecting column, the first level bubble 320 is arranged on the measuring dial 310 and at least partially serves as the auxiliary handle 380, the middle part of the measuring dial 310 is provided with the compass 360, and the annular scale 340 is arranged on the ruler case 100 corresponding to the measuring dial 310, and the bottom wall of the ruler case 100 serves as the measuring reference surface 110. Therefore, during 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 level 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 an inclined surface, and if the liquid level is parallel to the horizontal plane or the first level bubble 320 is in the middle position, it indicates that the surface to be measured is a flat surface. If it is measured that the surface to be measured is an inclined surface, the inclination angle of the surface to be measured can be obtained through the cooperation of the first level bubble 320 and the annular scale 340; then if the inclined surface to be measured needs to be leveled, after the surface to be measured is manually adjusted, the tape measure is placed on the surface to be measured after adjustment, and the liquid level in the first level bubble 320 is observed until the liquid level of the first level bubble 320 is parallel to the horizontal plane, thereby completing the leveling of the inclined surface to be measured. When direction discrimination is needed, the direction can be indicated by the compass 360, thereby achieving the purpose of discriminating the direction. During the whole process, the level and inclination of the surface to be measured, the leveling of the inclined surface to be measured, and the direction discrimination in special environments 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. Since the first level bubble 320 at least partially serves as the auxiliary handle 380, the convenience of rotating the measuring dial 310 is improved through the auxiliary handle 380, thereby further improving the operation efficiency.
[0038] The connecting column can be arranged on the side of the measuring dial 310 close to the ruler case 100 or directly arranged 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 end of the connecting column penetrates 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 middle part of the measuring dial 310 is provided with a circular accommodating cavity, the center of the circular accommodating cavity is concentrically arranged with the center of the measuring dial 310, the compass 360 is arranged in the circular accommodating cavity, and 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.
[0040] Preferably, the first level bubble 320 is arranged as a first cylindrical level bubble, and when the measuring reference surface 110 is placed on the horizontal plane, the axis of the cylindrical level bubble is parallel to the horizontal plane. Figure 1 andFigure 2 As shown, in this way, the area of the observation liquid surface of the first cylindrical horizontal bubble is increased as much as possible, so that the operator can easily observe the first cylindrical horizontal bubble, thereby improving the accuracy of the observation result.
[0041] As a further technical solution, the first horizontal bubble 320 is arranged as a first annular horizontal bubble, and the center of the first annular horizontal bubble is arranged concentrically with the center of the measuring dial 310. During use of the tape measure, the level and the inclination of the surface to be measured can be determined by observing the liquid surfaces on both sides of the first annular horizontal bubble, and the leveling process of the inclined surface to be measured can be completed. For example, when the liquid surfaces on both sides of the first annular horizontal bubble are on the same horizontal plane, it indicates that the surface to be measured is a plane, and when there is a height difference between the liquid surfaces on both sides of the first annular horizontal bubble, it indicates that the surface to be measured is an inclined plane. The liquid surfaces on both sides are adjusted to be on the same horizontal plane, and it indicates that the leveling process of the inclined surface to be measured is completed.
[0042] Preferably, the measuring assembly 300 further comprises at least one second horizontal bubble 350, and the second horizontal bubble 350 is arranged on the top wall 130 or the second side wall 140 of the tape housing 100.
[0043] The second horizontal bubble 350 can be arranged only on the top wall 130, and the liquid surface of the second horizontal bubble 350 on the top wall 130 is observed to determine whether the surface to be measured is a plane in the thickness direction of the tape measure; the second horizontal bubble 350 can be arranged only on the second side wall 140, and the liquid surface of the second horizontal bubble 350 on the second side wall 140 is observed to determine whether the surface to be measured is a plane in the height direction of the tape measure; or the second horizontal bubble 350 can be arranged on both the top wall 130 and the second side wall 140. The specific arrangement mode is adaptively selected according to actual needs. In this embodiment, the second horizontal bubble 350 is arranged on the top wall 130.
[0044] The second horizontal bubble 350 is arranged as a second cylindrical horizontal bubble, and the axis of the second cylindrical horizontal bubble is perpendicular to the axis of the first horizontal bubble 320; or the second horizontal bubble 350 is arranged as a second annular horizontal bubble. The specific arrangement mode is adaptively selected according to actual needs. In this embodiment, the second horizontal bubble 350 is arranged as a second cylindrical horizontal bubble.
[0045] Preferably, the measuring assembly 300 further comprises a laser projecting member. By arranging the laser projecting member, a specific angle can be drawn on the reference surface. Specifically, the tape measure is placed on the surface to be measured through the measuring reference surface 110, and then the laser projecting member is started. 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 member and the reference surface form a target angle. Then, the drawing process is completed according to the projected laser.
[0046] 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 shell 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; the laser projection member is arranged in a staggered manner with the first level bubble 320, and in the process of measuring the level and the inclination of the surface to be measured and leveling the surface to be measured, 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 level bubble 320.

[0048] Further, the laser projection member is at least part of the auxiliary handle 380 of the measurement dial 310. In this way, the convenience of the measurement dial 310 is improved, and the structure on the measurement dial 310 is simplified as much as possible to improve the appearance of the tape measure.
[0049] Preferably, the measurement assembly 300 further comprises an angle pointer 330, which is correspondingly arranged on the measurement dial 310. The angle pointer 330 can be integrally formed on the first cylindrical level bubble, or can be separately formed with the level bubble and then fixedly arranged on the measurement dial 310. In the two arrangement modes, the extension direction of the angle pointer 330 is parallel to the axis of the first cylindrical level bubble. In the observation process, the angle pointer 330 is used to further improve the observation accuracy of the first cylindrical level bubble.
[0050] Preferably, the first level bubble 320 and the laser projection member are located on both sides of the compass 360. In this way, since the first level bubble 320 and the laser projection member are arranged oppositely, when the compass 360 indicates the direction, the first level bubble 320 and the laser projection member can be used as the reference for direction indication, for example, the first level bubble 320 indicates north, and the laser projection member indicates south. At the same time, the first level bubble 320 and the laser projection member are used as two auxiliary handles 380 arranged oppositely on the measurement dial 310, which further improves the convenience when the measurement dial 310 is actuated.
