Description

Technical Field

[0001] The present application relates to the technical field of building construction tools, and specifically discloses a detection ruler. Background Art

[0002] During the construction process, many different types of equipment and devices are needed. Some devices are used during the construction process, and some devices are used in the inspection process after the construction is completed.

[0003] Now, let's focus on the detection device used in the house quality inspection process after the completion of the house: the detection ruler. In the prior art, the detection ruler is usually composed of two assembled ruler bodies. The ends of the two ruler bodies are hinged and can rotate relative to each other to achieve the purpose of detecting the angle of the wall corner. The ruler body can also detect the wall thickness. However, because the ends of the two ruler bodies are hinged together and difficult to separate, it is impossible to measure the angle of the wall corner of some Z-shaped walls with a small corner span.

[0004] Therefore, in view of this, the inventor provides a detection ruler to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that a traditional measuring ruler cannot measure the angle of a Z-shaped wall due to the length limitation of the ruler body because the ends of the two ruler bodies are hinged together.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the present utility model provides a detection ruler, including a main scale and several sub-scales. The main scale is provided with a sliding groove for accommodating the sub-scales to slide therein and extending to one end face. The main scale is also provided with limit grooves respectively connected to the sliding grooves. The sub-scales are all fixed with threaded rods passing through the limit grooves. The threaded rods are perpendicular to the plane in which the sub-scales slide. A section of the threaded rods extending out of the limit grooves is threadedly connected to a nut. A circumferential scale is also engraved on the top of the threaded rods, and scale lines are engraved on both the main scale and the sub-scales.

[0007] Furthermore, when the sub-scale is perpendicular to the main scale, the scale lines on the main scale are aligned at 90° to the circumferential scale on the top of the threaded rod.

[0008] Furthermore, both side end surfaces of the main scale are provided with sliding grooves facing inwards.

[0009] Furthermore, the top surfaces of both ends of the main scale are provided with positioning grooves which are connected with the limiting grooves and for the nuts to be placed therein.

[0010] Furthermore, when the nut is placed in the positioning groove and when the sub-scale is perpendicular to the main scale, the side wall of the sub-scale is flush with the outer end surface of the main scale.

[0011] Furthermore, the length of the ruler is not shorter than the length of the chute.

[0012] The principle and effect of this solution are:

[0013] 1. Compared with the prior art, the slide groove on the main ruler of the utility model can simultaneously install multiple sub-rules, which can be freely combined and measure objects at multiple angles at the same time.

[0014] 2. Compared with the existing technology, the present invention can measure Z-shaped walls. The end of the main ruler is pressed against one side of the Z-shaped wall, and the main ruler and the sub-rule are combined to form an L-shaped structure. The sub-rule is pressed against the other side of the wall, and the thickness of the Z-shaped wall can be read from the scale lines on the main ruler. This solves the problem that traditional measuring rulers cannot measure the angle of the Z-shaped wall due to the length limitation of the ruler body because the ends of the two ruler bodies are hinged together.

[0019] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0020] The reference numerals in the drawings of the specification include: main scale 1, slide groove 2, limit groove 3, sub-scale 4, threaded rod 5, nut 6, wall 7, positioning groove 8.

[0021] A detection ruler, for example Figure 1 As shown:

[0022] It comprises a main scale 1 and sub-scales 4 installed on both sides of the main scale 1, and the main scale 1 and sub-scales 4 have the same thickness.

[0023] Both side end faces of the main scale 1 are provided with inwardly-opened chutes 2, into which the sub-scale 4 can be inserted and slides, and the length of the sub-scale 4 is longer than the length of the chute 2, and the top and bottom surfaces of the sub-scale 4 are respectively fitted with the top and bottom surfaces of the chute 2. Limiting grooves 3 communicating with the chute 2 are also respectively opened on both sides of the main scale 1, and the limiting grooves 3 and the chute 2 are perpendicular to each other.

[0024] In this embodiment, each scale 4 has a through-hole through which a threaded rod 5 is fixedly mounted. The ends of the threaded rod 5 extend out from the end faces of the scale 4, respectively. The threaded rod 5 passes through and slides within the retaining slot 3, with the threaded rod 5 perpendicular to the plane in which the scale 4 slides. When measuring the thickness of a wall 7, after the scale 4 is in contact with the sidewall of the wall 7, nuts 6 can be screwed into the ends of the threaded rod 5. These nuts 6 at both ends of the threaded rod 5 clamp the main scale 1, fixing the position and angle of the scale 4.

[0025] Furthermore, a circumferential scale is engraved on the top of the threaded rod 5, and continuous scale lines are engraved on both the main scale 1 and the minute scale 4.

[0026] like Figure 3 As shown, the top and bottom surfaces of both ends of the main scale 1 are provided with positioning grooves 8 that communicate with the stop slots 3 and accommodate the nuts 6. When the nuts 6 are inserted into the positioning grooves 8 and the sub-scale 4 is perpendicular to the main scale 1, the outer sidewalls of the sub-scale 4 are flush with the outer end surfaces of the main scale 1. On the main scale 1, scale lines are engraved between the two positioning grooves 8, with the starting ends of the scale lines aligned with the axes of the positioning grooves 8. The positioning grooves 8 are bilaterally symmetrical about the scale lines. In this embodiment, when the sub-scale 4 is perpendicular to the main scale 1, the scale lines on the main scale 1 are aligned at 90° to the circumferential scale at the top of the threaded rod 5.

[0027] When the utility model is used, Figure 1 As shown, for measuring the thickness of the wall 7: For a directly protruding wall 7, first install the scales 4 into the slots 2 on both sides of the main scale 1. Then, fit the scales 4 to the two sides of the wall 7 and secure them with the nuts 6. Then, read the scale lines between the scales 4 on both sides of the main scale 1 to determine the thickness of the wall 7. Based on the position of the circular scales at the top of the threaded rods 5 on both sides of the scales 4, if the scale lines on the main scale 1 align with the 90° of the circular scales, it means that the wall 7 is vertical at the corner. If they are not aligned, the deviation angle is the deviation angle of the wall 7 at the corner.

[0028] like Figure 2As shown, for measuring the thickness of a Z-shaped wall 7: only install the sub-rule 4 in the chute 2 on one side of the main ruler 1. If the thickness of the wall 7 to be measured is greater than the depth of the chute 2, select the chute 2 on the other side to install the sub-rule 4. Then, directly place the end of the main ruler 1 against the wall 7, and let the installed sub-rule 4 fit the side wall of the other section of the wall 7. This will achieve the thickness measurement of the Z-shaped wall 7.

[0029] The present invention can not only measure the thickness of the wall 7, but also detect the flatness of the wall 7: a sub-rule 4 is installed on one or both sides of the main ruler 1, so that the main ruler 1 and the sub-rule 4 are on the same horizontal line, and the main ruler 1 and the sub-rule 4 are attached to the surface of the wall 7, and the scale of the threaded rod 5 of the sub-rule 4 is observed. When the scale line on the main ruler 1 is aligned with the 0° or 180° on the threaded rod 5, it indicates that the surface of the wall 7 is level.

[0030] The utility model can not only detect the thickness of the wall 7 and the flatness of the wall 7, but also measure the length by the scale lines on the main ruler 1 and the sub-ruler 4;

[0031] Moreover, the slide grooves 2 on both sides of the main scale 1 can simultaneously install multiple sub-scales 4, which can be freely combined to measure objects at multiple angles at the same time.

[0032] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
