The utility model discloses a two-sided tape measure of shell area scale reforms transform on the basis of traditional scale bar 101, makes its shell 100 have the scale, when the distance between two objects in the narrow space on the bridge need be measured, can have two kinds of use cases:

first, when the distance between two objects in a narrow space is short, such as measuring a gap in a narrow space, it is not suitable to use the scale bar 101 for measurement, and the case 100 of the case can be directly used for measurement to use the case 100 of the case as a small ruler. The ruler box is provided with a horizontal bubble which can level the length standard scale 106. At the same time, the accuracy of the length standard scale 106 on the scale surface 103 can be set to be higher than that of the scale bar 101, such as: 0.5MM (the precision of the common scale bar 101 is 1MM), so that the high accuracy of the measurement result can be ensured.

Secondly, when the distance between two objects in a narrow space is slightly longer, the locating plane 105 of the ruler box shell 100 is abutted against one of the two objects to be measured, the scale bar 101 is pulled out, the end part of the scale bar is abutted against the other of the two objects to be measured, and the horizontal bubble is adjusted, so that the distance between the two objects to be measured is obtained by adding the reading of the scale bar 101 and the length of the standard length scale 106.

Specifically, referring to fig. 4 and 5, the present invention provides two practical application scenarios of the double-sided tape measure with scale on the housing. The distance between the upper leveling steel plate 115 and the lower leveling steel plate 116 in fig. 4 is suitable for the second measurement scenario described above. The distance measurement between the first structure 117 and the second structure 118 is also applicable to the second measurement scenario described above when the first structure 117, the second structure 118, and the obstacle 119 are all in a confined space in fig. 5. When the distance between the obstacle 119 and the second structure 118 is required, the second measurement method is adopted to measure the distance, the turning of the human hand and the stretching of the scale bar 101 are limited, and the measurement is inconvenient. Therefore, it is convenient to apply this kind of situation to the first measurement scenario described above.

In particular, in the present embodiment, the length standard scale 106 is marked on both scale surfaces 103, so that any one of the two scale surfaces 103 can be read during the test, and the situation that the ruler box needs to be turned over in a narrow space is avoided.

In the embodiment, as shown in fig. 1, a covered edge 108 is provided at the bottom of the scale surface 103, and the length standard scale 106 is marked on the covered edge 108. The purpose of the edge cover 108 is to distinguish the colors of the edge cover 108 and the shell 100, so that no visual interference is generated during reading; the double edge 108 is made of stainless steel sheet, which can reinforce the shell 100 and prolong the service life of the tape measure.

As shown in fig. 1, the leveling surface 105 is provided with a receiving groove 109, and the extending direction of the receiving groove 109 is arranged along the upper and lower directions of the housing 100 shown in fig. 1. An extension plate 113 for increasing the length of the leveling surface 105 is arranged in the accommodating groove 109, and the surface of the extension plate 113 facing away from the opening surface 104 is flush with the leveling surface 105. The extended screed 105 may be applied to a scene such as that shown in FIG. 5. The surface of the elongated plate 113 facing away from the opening surface 104 is flush with the leveling surface 105, and the distance between the surface and the opening surface 104 is equal to the distance between the leveling surface 105 and the opening surface 104, and the distance between the two objects is still equal to the sum of the distance between the leveling surface 105 and the opening surface 104 (i.e. the length of the length standard scale 106) and the reading of the scale strip 101.

Specifically, as shown in fig. 1 and 3, a sliding slot 110 is disposed in the accommodating slot 109 along the extending direction thereof, a sliding piece 111 adapted to the sliding slot 110 is disposed on the elongated plate 113, and the sliding piece 111 can slide in the sliding slot 110. The end of the sliding slot 110 is provided with a stopper for preventing the extension board 113 from sliding out of the receiving slot 109. When the elongated plate 113 is used, the elongated plate 113 is pushed out from the storage groove 109, and when the elongated plate 113 is not used, the elongated plate 113 is pushed back into the storage groove 109.

In other embodiments, as shown in fig. 1, the elongated plate 113 may be hinged in the receiving slot 109. The elongated plate 113 is configured to be flipped downward to be flipped out of the receiving slot 109 and flipped 180 ° to the condition shown in fig. 1, so that the length of the leveling surface 105 is increased; or turned 180 degrees upward to be received in the receiving groove 109 for carrying or measuring.

As shown in fig. 2, the first horizontal bubble 107 and the second horizontal bubble 114 are both disposed on the same scale surface 103. Meanwhile, in the two scale surfaces 103 of the present embodiment, the other scale surface 103 is also provided with a third horizontal bubble and a fourth horizontal bubble, and the relationship of the two scale surfaces 106 is similar to a mirror image. Thus, since the length standard scales 106 are marked on the two scale surfaces 103 and horizontal bubbles in the horizontal direction and the vertical direction are arranged on the two scale surfaces 103, the two scale surfaces 103 can be accurately measured. Specifically, when in the use scenario as shown in fig. 4, a first horizontal bubble 107 perpendicular to the extending direction of the length scale 106 is used. When in the use scenario as shown in fig. 5, a second horizontal bubble 114 is used which is parallel to the extension of the length scale 106.

As shown in fig. 2, a flange 112 is provided at the end of the scale strip 101 that extends out of the opening to prevent the scale strip 101 from retracting back into the cavity. A locking switch 102 provided on the housing 100 can temporarily stop the retraction of the scale bar 101 for measurement and reading.
