[0023] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention. Example
[0024] The multifunctional standard ruler for building inspection described in this embodiment comprises a main ruler 1 arranged horizontally and a secondary ruler 8 arranged vertically. The right side wall of the main ruler 1 is provided with a connecting block 12 flush with the top thereof. Figure 1 As shown, the upper end of the front side wall of the main ruler 1 is provided with a first scale line 4, the right end of the front side wall of the auxiliary ruler 8 is provided with a second scale line 9, and the front side wall of the connecting block 12 is provided with a third scale line 11, wherein the main ruler 1 and the auxiliary ruler 8 are used for distance measurement when used with the first scale line 4 and the second scale line 9, and are used for angle measurement when used with the third scale line 11;
[0025] The right side wall of the connecting block 12 is provided with an installation groove that is connected up and down, one end of the secondary ruler 8 is located in the installation groove, and the rear side wall of the installation groove is provided with a fixed shaft 16 with one end fixed thereto, and the secondary ruler 8 is provided with a slide groove that is connected front and back, and a slider 18 that slides up and down with the slide groove is provided in the slide groove, and the slider 18 is mounted on the fixed shaft 16 and rotates with it. The top of the main ruler 1 and the connecting block 12 are provided with a groove for the secondary ruler 8 to rotate to a horizontal state. In this embodiment, under the action of the slider 18 and the fixed shaft 16, the secondary ruler 8 can be rotated around the fixed shaft 16 and moved along the direction of the slide groove, so that it can be used for various types of angle measurements of buildings, such as the verticality of the wall, the angle between the wall, etc., and can also extend the single measurement range of the main ruler 1 and reduce the error in measuring longer distances; Figure 3 and Figure 5 As shown, the fixed shaft 16 and the rear side wall of the mounting groove are perpendicular to each other, and the slider 18 is in an "I"-shaped structure as a whole, so that it can only slide along the direction of the slide groove. A through hole for the fixed shaft 16 to pass through is opened in the middle of the slider 18, and the aperture of the through hole is the same as the diameter of the fixed shaft 16, so as to avoid shaking; when the secondary ruler 8 is in a vertical state, the right side wall of the secondary ruler 8 is flush with the right side wall of the connecting block 12, and when the secondary ruler 8 is in a horizontal state, the top of the secondary ruler 8 is flush with the top of the main ruler 1;
[0026] The other end of the fixed shaft 16 passes through the front side wall of the connecting block 12 and is fitted with a fixing block 10 that is threadedly matched therewith. A connecting rod 7 is fixed to the side wall of the fixing block 10 (the fixing block 10 and the connecting rod 7 in this paragraph constitute as a whole the limiting mechanism for fixing the position of the fixing shaft 16 after sliding or rotating. In actual application, only the fixing block 10 may be provided). In this embodiment, the front and rear parts of the right end of the connecting block 12 are brought closer to each other by rotating the fixing block 10, and then the slider 18 and the secondary ruler 8 are clamped, so as to fix the position of the secondary ruler 8 after rotation or movement. The connecting block 12 and the slider 18 are both made of plastic with a certain elasticity. At the same time, the connecting block 12 is made of transparent material. An indicating arrow 17 for indicating the rotation angle of the secondary ruler 8 is fixed to the side wall of the slider 18. Figure 1 , Figure 3 and Figure 5 As shown, it is more convenient for the staff to read the angle between the main ruler 1 and the auxiliary ruler 8;
[0027] like Figure 3 As shown, the front side wall and the rear side wall of the installation groove are fixed with anti-skid pads 19, and the anti-skid pads 19 can increase the friction between the slider 18 and the connecting block 12, so that the secondary ruler 8 can be kept in the current position when the fixing block 10 is loose and the secondary ruler 8 is not subjected to force, and the fixing effect of the secondary ruler 8 after the fixing block 10 is tightened can be improved;
[0028] like Figure 1 and Figure 4 The cam 20 is provided with a plurality of cams 21 and 22, and the cam 20 is provided with a plurality of cams 22, 22 and 22. The cam 20 is provided with a plurality of cams 21 and 22, and the cam 20 is provided with a plurality of cams 22. Figure 1 As shown, the zero scale line of the first scale line 4 is aligned with the left side wall of the sliding plate 3, so as to facilitate the reading of the staff;
[0029] The front side wall of the main ruler 1 is provided with a plurality of level bubbles 5, such as Figure 1As shown, there are three vials 5, and the three vials 5 are respectively in horizontal, vertical and 45° inclined states, so that the device can also measure the horizontality, verticality and 45° inclination.
[0030] When this embodiment is used for angle measurement, firstly, the top of the main ruler 1 is attached to a measuring plane, then the fixing block 10 is loosened and the right side wall of the secondary ruler 8 is attached to another measuring plane, then the fixing block 10 is tightened and the reading is made using the indicating arrow 17 and the third scale line 11, so as to obtain the angle between the two measuring planes; and when it is used for distance measurement, firstly, the secondary ruler 8 is rotated to a horizontal state so that the secondary ruler 8 is stored in the groove, and then the main ruler 1 and the first scale line 4 are directly used for measurement. When the length of the measured object is greater than the maximum value of the first scale line 4, first, the fixing block 10 is loosened and the secondary ruler 8 is horizontally rotated to the right. Move it out of the groove until the maximum value of the first scale line 4 is aligned with the zero scale value of the second scale line 9, and then tighten the fixing block 10, after which the distance can be measured again; secondly, when using it to measure the thickness of the wall, first push the sliding plate 3 out of the storage slot, and at the same time, the sliding plate 3 is automatically fixed in position under the action of the thrust block 2, and then the sliding plate 3 is hooked on the wall and the top of the main ruler 1 is attached to the wall, and the final reading completes the measurement of the wall thickness; finally, when measuring the horizontality, verticality and 45° inclination of the building, directly stick the top of the main ruler 1 on the side and observe the corresponding level bubble 5. Example
[0031] This embodiment further illustrates the technology. A slot is provided at the lower end of the right side wall of the main ruler 1. An insert block 13 is fixed to the left side wall of the connecting block 12. The insert block 13 is inserted into the slot and fixed by a fixing bolt 14. The connecting block 12 is detachably mounted on the right side wall of the main ruler 1 by the insert block 13 and the fixing bolt 14, so that the connecting block 12 can be separated from the main ruler 1, so that the auxiliary ruler 8 can be used for angle measurement in a narrow space area and for drawing lines at a certain angle. Example
[0032] This embodiment further illustrates the technology. A toggle plate 6 is fixed to the front side wall of the connecting rod 7. Figure 1 , Figure 2 and Figure 3 As shown, it is more convenient and labor-saving to drive the fixing block 10 to rotate by the toggle plate 6.
