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.

Embodiment 1: A vertical detection ruler, as shown in Figure 1, includes two ruler bodies 1 connected by hinges 2, the hinge 2 is arranged at the middle position of the two ruler bodies 1 along the length direction, and one ruler body 1 is relatively detected A level pipe 3 is fixed on one side of the surface, and an instrument panel 4 for displaying verticality is fixed on the side opposite to the hinged surface.

Referring to Figures 1 and 2, a locking device is also passed between the two ruler bodies 1 to fix the two ruler bodies 1 in a horizontal or vertical state, which is convenient for detecting a long measured object or for easy storage; the locking device is arranged on the ruler The body 1 is composed of the first locking device 8 on the side opposite to the detection surface and the second locking device 9 arranged on the side of the scale body 1 opposite to the hinged surface. The first locking device 8 and the second locking device 9 are set the same. The first locking device 8 comprises fixing bolts 81 threadedly engaged with the two ruler bodies 1 respectively, and a connecting plate 82, through the through hole provided at one end of the connecting plate 82 for passing through the fixing bolt 81, and the rotation fastened at the other end to be connected to the other The chute on the one fixing bolt 81 connects the two fixing bolts 81 together so that a stable triangle is formed between the two feet 1 and the connecting plate 82, and the two feet 1 are fixed into a closed vertical state, which is convenient for transportation Or store the test ruler.

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 is fixed on the instrument cover 5, which is inserted into the draw-in groove on the instrument panel 4 by the elastic block, and the cover is closed 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 of Embodiment 1: When it is necessary to detect the levelness and verticality of a long measured object, the two ruler bodies 1 are unfolded in a horizontal state by rotating the two ruler bodies 1 relative to the hinge 2, and the two ruler bodies 1 are unfolded in a horizontal state. 1 The connecting plate 82 on one side of the hinged surface connects the two fixing bolts 81 together so that the ruler body 1 will not bend during the detection process. When the distance is not enough, extend the ruler 10 in the ruler body 1 Slide inside to further lengthen the detection distance of the detection ruler to detect the measured object; when the detection ruler needs to be put away, close the ruler body 1 on both sides to a vertical state, and connect the two fixing bolts 81 through the connecting plate 82 on the opposite detection surface. Connect together to make the two ruler bodies 1 fixed in a vertical state, shorten the length of the detection ruler, and facilitate storage.

Embodiment 2: As shown in Figure 5, the difference from Embodiment 1 is that the above-mentioned locking device consists of fixing bolts 81 respectively arranged on the opposite detection surface of the two ruler bodies 1, and a connecting plate is passed between the two fixing bolts 81. 82 are connected, because the through holes provided at the two ends of the connecting plate 82 respectively for the fixing bolts 81 to pass through, when the two fixing bolts 81 pass through the connecting plate 82 and the ruler body 1 is threaded and fixed, the two ruler bodies 1 can only hold one form, and then through the vertical state and the horizontal state of the two ruler bodies 1, the distance between the two fixing bolts 81 is equal, so that when the connecting plate 82 is connected to the two fixing bolts 81, the two ruler bodies 1 can only be fixed in the vertical state or level state.
