[0028] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following will be combined with the drawings to the each embodiment of the utility model carries out the detailed elaboration. However, the ordinary skilled in the art can understand that, in each embodiment of the utility model, in order to make the reader better understand the present application and proposed many technical details. However, even if there is no these technical details and based on each embodiment of the various changes and modifications, the technical scheme claimed by each claim of the present application can be realized.

[0029] As Figures 1-2As shown in the utility model, one embodiment of the utility model relates to a portable perpendicularity measuring scale, including tower scale 30 and telescopic rod 10, one end of tower scale 30 is vertically fixedly connected and is equipped with a plate-shaped base 40, the one side of base 40 and tower scale 30 is connected is connecting surface 42, the back of connecting surface 42 is locating surface 43, telescopic rod 10 one end is hinged with base 40 through hinging device 50, and telescopic rod 10 and tower scale 30 are located the same side of base 40. Through the setting of the hinge connection of telescopic rod 10 and base 40, handheld telescopic rod 10 is forced towards base 40, can make the locating surface 43 of base 40 closely adhere to the base surface 60 to be measured, so that tower scale 30 is perpendicular to the base surface 60 to be measured, and the scale value of the laser plane projection on tower scale 30 is read, and the tower scale 30 reading of different positions of the base surface 60 to be measured is obtained by moving base 40, and the perpendicularity measurement can be conveniently completed. Preferably, base 40 is made of light high-strength material, which ensures durability while further increasing the portability of the overall device. In order to further increase the durability of the portable perpendicularity measuring scale, tower scale 30 and telescopic rod 10 are also made of light high-strength material. The above-mentioned light high-strength material can be selected from aluminum alloy, magnesium alloy, fiber reinforced plastic and the like in the prior art.

[0030] As Figures 3-4 shown, the first embodiment of the utility model relates to a portable perpendicularity measuring scale, including tower scale 30 and telescopic rod 10, tower scale 30 is vertically fixedly arranged at the edge of connecting surface 42 of base 40 along the transverse direction, and telescopic rod 10 is hingedly arranged at the central position of connecting surface 42 of base 40 along the transverse direction, so that when telescopic rod 10 is forced towards base 40, the force of base 40 is balanced, and the locating surface 43 of base 40 can be stably attached to the base surface 60 to be measured.

[0031] As Figures 5-7As shown, in the second embodiment of this utility model, a portable verticality measuring ruler is provided, including a leveling rod 30 and a telescopic rod 10. The leveling rod 30 is vertically fixed at the center of the connecting surface 42 of the base 40 in the transverse direction. The end of the telescopic rod 10 extends axially and is provided with a hinge seat 20. The end of the hinge seat 20 away from the telescopic rod 10 is hinged to the base 40 by a hinge device 50, which is symmetrically arranged on both sides of the leveling rod 30. Preferably, the hinge seat 20 is provided with a clearance hole 21, the central axis of which coincides with the central axis of the telescopic rod 10. The end of the hinge seat 20 away from the telescopic rod 10 is hinged to the base 40 by the hinge device 50, which is symmetrically arranged on both sides of the leveling rod 30. The leveling rod 30 and the telescopic rod 10 are located on the same side of the base 40, and the leveling rod 30 passes through the clearance hole 21 and is positioned above the telescopic rod 10. The wall of the telescopic rod 30 and the clearance hole 21 can stop and limit the telescopic rod 10 when it rotates along the hinge axis, thus limiting the rotation range of the telescopic rod 10. This not only meets the needs of folding and carrying the telescopic rod 10 and the telescopic rod 30, but also effectively prevents the telescopic rod 10 from directly contacting the telescopic rod 30, thus avoiding damage to the telescopic rod 30 caused by the impact of the telescopic rod 10.

[0032] like Figures 8-9 As shown, in the third embodiment of this utility model, a portable verticality measuring ruler is involved. The difference between this embodiment and the second embodiment is that the base 40 has an extension portion 41 extending upward along its plane, making the base 40 as a whole T-shaped structure. In use, the positioning surface 43 of the base 40 is in contact with the base surface 60 to be measured, and the extension portion 41 is located on the upper part of the base 40 and is set in contact with the base surface 60 to be measured. The setting of the extension portion 41 effectively increases the contact area between the base 40 and the base surface 60 to be measured, which is beneficial to the stability of the contact and positioning of the base 40 and the base surface 60 to be measured. At the same time, when the telescopic rod 10 acts on the base 40 to make the base 40 contact the base surface 60 to be measured, the setting of the extension portion 41 helps to assist the positioning of the positioning surface 43 of the base 40, preventing the lower edge of the base 40 from lifting when excessive force is applied, so as to ensure the accuracy of the contact between the positioning surface 43 of the base 40 and the base surface 60 to be measured. Preferably, the position where the telescopic rod 10 is hinged to the base 40 is higher than the connection position between the measuring rod 30 and the base 40, which can effectively increase the torque of the telescopic rod 10 on the base 40, and help reduce the labor intensity of the measuring personnel.

[0033] In one embodiment of this utility model, the scale 30 is cylindrical, and the circumference of the scale 30 is provided with annular scale, so that the scale on the scale 30 can be read from multiple angles, so as to facilitate reading the position of the laser plane projected on the scale 30; preferably, the scale 30 is a pull-out multi-section telescopic structure, and a retaining spring structure is provided between two adjacent telescopic sections. The scale 30 adopts a pull-out contraction and extension, and adopts a multi-section nesting method. When each telescopic section is pulled out, a retaining spring pops out to limit it. In an exemplary example, the scale 30 has 5 sections, and the length of each section is 10 centimeters.

[0034] In one embodiment of this utility model, the telescopic rod 10 is a pull-out multi-section telescopic structure, with a retaining spring structure between adjacent telescopic sections. The retractable tube adopts a pull-out retraction and extension method, and is arranged in a multi-section nested manner. Each telescopic section is limited by a retaining spring when it is pulled out. In an exemplary example, the retractable tube has 10 sections, each section being 15 centimeters long.

[0035] During construction, inspectors will use the laser plane projected by a laser level to measure the distance difference between each point on the base surface 60 and the laser plane using a portable verticality measuring ruler provided by this invention to determine if the distance meets the accuracy requirements. The specific steps are as follows: After setting up the laser plane, the leveling rod 30 with a base 40 is raised to the measuring point on the base surface 60 using the telescopic rod 10. Force is applied towards the base surface 60 using the telescopic rod 10, causing the positioning surface 43 of the base 40 to align with the base surface. The scale position of the laser plane projected onto the leveling rod 30 is read and recorded. This operation is repeated at the remaining measuring points on the base surface 60. The difference between the measured values ​​is compared to determine if it is within the allowable error range, thus confirming whether the plane verticality meets the requirements. If the distance between the laser plane and the base surface 60 is far due to limited space or other reasons, the leveling rod 30 can be extended. When it is necessary to inspect the high points of the base surface 60 for beams, slabs, and columns, there is no need to set up a ladder; simply extending the telescopic rod 10 allows for smooth inspection.

[0036] This utility model provides a portable verticality measuring ruler. A base is vertically fixed to one end of the ruler, and a telescopic rod is hinged to the base. The telescopic rod and the ruler are positioned on the same side of the base. The force applied by the telescopic rod ensures the base is in close contact with the surface to be measured, thus making the ruler perpendicular to the surface. The scale value projected onto the ruler by a laser plane is read. By moving the base, ruler readings at different positions on the surface to be measured are obtained. This allows for accurate measurement of multiple points on beams, slabs, and columns. The structure is simple, the use is convenient, and verticality measurement can be performed relatively easily.

[0037] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
