detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail.

This specific embodiment is only an explanation of the utility model, and it is not a limitation of the utility model. After reading this description, those skilled in the art can make modifications to the embodiment without creative contribution according to needs, but as long as it is within the utility model All new inventions are protected by patent law.

A vertical detection ruler, as shown in Figure 1, includes two ruler bodies 1 that are rotatably connected by a hinge 2, the hinge 2 is arranged at the middle position of the two ruler bodies 1 along the length direction, and one of the ruler bodies 1 is on the side opposite to the detection surface A level tube 3 is fixed, and an instrument panel 4 for displaying verticality is fixed on the side opposite to the hinged surface.

With reference to Fig. 1 and 2, two ruler bodies 1 are provided with the T-shaped slot 81 that communicates with each other on one side of the relative hinge surface, and the T-shaped block 8 that slides in T-shaped groove 81 is installed on its one ruler body 1, when two When the scale body 1 is unfolded in a horizontal state to detect the measured object, slide the T-shaped block 8 in the T-shaped slot 81, pop out a spring clamp 9 and insert it into the second connection hole 84 of the T-shaped block 8, Restrict the continuous sliding of the T-shaped block 8 so that its two ends are respectively snapped into the T-shaped groove 81 of the two-foot body 1, restrict the continuous rotation of the two-foot body 1, and maintain a horizontal state to make the detection result more accurate. When the scale body 1 is closed, the extruded spring block 9 is disengaged from the second connection hole 84, and the T-shaped block 8 is slid into one of the scale body 1, and then the spring block 9 is snapped into the first connection hole 83, and the T-shaped block 9 is inserted into the first connection hole 83. The type block 8 is hidden in the T-shaped groove 81; wherein the spring block 9 is composed of a spring 91 and a block 92 fixed to one end of the spring 91, and the other end of the spring 91 and the ruler body 1 are perpendicular to the T-shaped block 8. The vertical groove 93 is fixedly connected so that the clamping block 92 slides up and down in the vertical groove 93, and is inserted into the T-shaped block 8 or hidden in the vertical groove 93, and then is fixed toward the end of the spring 91 by the clamping block 92 and is wider than the clamp. The block 92 is a limiting block, which slides the block 92 inseparably in the vertical groove 93 to prevent the block 92 from breaking away from the vertical groove 93 (refer to FIG. 5 ).

Referring to Figures 2 and 5, wherein the T-shaped block 8 is also embedded with a number of rolling balls 82 and the T-shaped groove 81 for rolling friction, reducing the friction between the T-shaped block 8 and the T-shaped groove 81, so that the T-shaped block 8 slides more relaxed.

Referring to Fig. 3 , one ruler body 1 is fixed with a hasp lock 15 on the opposite detection surface, and the other ruler body 1 is correspondingly fixed with a hasp seat 16 for buckling with the hasp lock 15, and the two ruler bodies 1 are vertically closed and stored. When getting up, lock the hasp lock 15 on the other chi body 1 on the buckle seat 16 on the other chi body 1, limit the continuous rotation of the two chi bodies 1, shorten the length of the detection chi, and be convenient to store.

Referring to Fig. 1, the above-mentioned two scale bodies 1 are respectively equipped with extension rulers 10 that slide back and forth relative to the scale body 1, and one end of the extension ruler 10 opposite to the scale body 1 is also fixed with a foot 12 that is flush with the detection surface of the scale body 1 , when the detection distance is not long enough after the two ruler bodies 1 are unfolded, the extension ruler 10 slides in the ruler body 1 to extend the detection distance of the detection ruler, and then the extension ruler 10 is fixed on the corresponding position of the ruler body 1 by the fixing device, Accurate detection of the measured object, wherein the fixing device is set as a fastening bolt 11 threaded with the ruler body 1. Under the force of the thread cooperation of the ruler body 1, one end of the fastening bolt 11 is pressed against the extension ruler 10, and the extension ruler 10 Fixed on the scale body 1.

With reference to Fig. 1, above-mentioned two scale bodies 1 intermediate positions are also respectively fixed with a convenient staff to hold the scale body 1 to shake hands 13, avoid scale body 1 slipping in the hands of the staff, and facilitate the operation of the staff.

Referring to Figures 1 and 4, an instrument cover 5 is also installed on the above-mentioned instrument panel 4, and the instrument cover 5 slides in the groove 7 of the instrument panel 4 through the protrusions on both sides to open or close the instrument display and protect the instrument display. The instrument is not damaged, wherein an elastic block 92 is fixed on the instrument cover 5, which is inserted into the draw-in groove on the instrument panel 4 by the elastic block 92, and is covered on the instrument display.

Referring to Figures 1 and 3, since the detection ruler is applicable to a wide range of environments, it is difficult for the staff to see the display status on the instrument panel 4 and the level tube 3 in some dim environments. 14. Play the role of illuminating the instrument panel 4 and the level tube 3 in a dark environment, so that the staff can clearly see the level and verticality of the measured object.

Working principle: When it is necessary to detect the levelness and verticality of a long measured object, by rotating the two-foot body 1 relative to the hinge 2, the two-foot body 1 is unfolded in a horizontal state, and the spring block 9 is squeezed. Under the elastic force of the spring 91, the block 92 is disengaged from the first connecting hole 83 of the T-shaped block 8, so that the T-shaped block 8 slides in the T-shaped groove 81. When the second connecting hole 84 communicates with the spring block 9 , the spring block 9 pops up and snaps into the second connection hole 84 under the force of the spring 91, so that the T-shaped block 8 is fixed at both ends and snapped into the two ruler bodies 1 respectively, so as to ensure that the ruler body 1 is in the detection process. There will be no bending phenomenon, and when the distance is not enough, slide the extended ruler 10 inside the ruler body 1 to further lengthen the detection distance of the detection ruler to detect the object under test; when the detection ruler needs to be put away, put the two sides The ruler body 1 is closed in a vertical state, and the buckle lock 15 on one ruler body 1 is fastened to the buckle seat 16 on the other ruler body 1, so that the two ruler bodies 1 are fixed in a vertical state, and the length of the detection ruler is shortened. length for easy storage.
