DETAILED DESCRIPTION

[0035] Examples of the utility model will be further described below in combination with the accompanying drawings.

[0036] As shown in FIGS. 1-5, the multi-functional level ruler includes a box body 1, where the box body 1 includes a top plate, a bottom plate, a front side plate, a back side plate, a left side plate and a right side plate, the box body 1 is internally mounted with a ruler-returning spring 3 and a tape measure 4, the ruler-returning spring 3 is wound on a shaft inside the box body 1, the tape measure 4 is connected with the ruler-returning spring 3 and wound on the ruler-returning spring 3, one end that is on the right side plate of the box body 1 and close to the back side plate is provided with an opening 2, one end of the tape measure 4 is provided with a stopper 5, the tape measure 4 is run out of the opening 2, and the stopper 5 is located at the opening 2.

[0037] The back side plate of the box body 1 is provided with a suction pad 6, a position that is on the bottom plate of the box body 1 and close to the opening 2 is hinged with a straight ruler 7, the top plate of the box body 1 is provided with a groove 9, a counterweight 10 is arranged in the groove 9, a position that is on the top plate of the box body 1 and close to the opening 2 is provided with a hanging shaft 11, and the counterweight 10 is connected to the hanging shaft 11 through a suspension wire 12.

[0038] The straight ruler 7 is internally provided with an installation groove, the installation groove is internally mounted with a telescoping ruler 14, and a surface of the telescoping ruler 14 is provided with a scale bar.

[0039] The bottom plate is provided with a receiving slot 8, and the straight ruler 7 is mounted in the receiving slot 8.

[0040] At least one suction pad 6 is provided.

[0041] An outer edge of the groove 9 is connected with a safety clip 13 through a rotary shaft.

[0042] The stopper 5 is provided with a horizontal bubble level.

[0043] The counterweight 10 is in a flat shape.

[0044] When the multi-functional level ruler is used, firstly, the counterweight 10 is taken out by opening the safety clip 13; then, the straight ruler 7 is rotated out from the receiving slot 8 and adjusted to be parallel with the suspension wire 12, and then the multi-functional level ruler is fixed on a wall surface by using the suction pad on the back side plate. The tape measure 4 is pulled out and adjusted to be horizontal.

[0045] If a length of a horizontal side of a measured photo frame is a and a length of a vertical side is b, a position of a fixing point in a horizontal direction may be determined by the tape measure 4, and a position of a fixing point in a vertical direction may be determined by the straight ruler 7.

[0046] The straight ruler 7 is internally provided with an installation groove, the installation groove is internally mounted with the telescoping ruler 14, and a surface of the telescoping ruler 14 is provided with a scale bar. The telescoping ruler 14 may be arranged in such a way that an application requirement of large-size photo frames can be satisfied.

[0047] The bottom plate is provided with the receiving slot 8, and the straight ruler 7 is mounted in the receiving slot 8. The straight ruler may be rotated out from the receiving slot 8 when it is to be used and rotated into the receiving slot 8 when it is not in use, and thus carrying is facilitated.

[0048] At least one suction pad 6 is provided to ensure that the multi-functional level ruler is firmly fixed on the wall surface.

[0049] The outer edge of the groove 9 is connected with the safety clip 13 through the rotary shaft. The safety clip 13 may be arranged in such a way that the counterweight 10 can be prevented from being released from the groove 9 when the counterweight is not in use.

[0050] The stopper 5 is provided with a horizontal bubble level that helps to adjust the tape measure 4 to be in a horizontal state.

[0051] The counterweight 10 is in a flat shape, facilitating being embedded into the groove 9.
