[0002] In the construction engineering, the wall surface perpendicularity is an important standard of ensuring the building structure stability, appearance and construction quality, and the wall surface perpendicularity detection device is used for measuring and confirming whether the wall surface meets the design requirement perpendicularity standard.

[0003] In the prior art, there are various tools for detecting the perpendicularity of the building, but the principles are basically similar, that is, a ruler is used and a level bubble or other device for detecting the perpendicularity is arranged on the ruler. SUMMARY

[0004] In view of the deficiencies in the prior art, the utility model provides a building perpendicularity detection device, which solves the problem of low detection accuracy of the existing building perpendicularity detection tool for the wall under certain conditions.

[0005] To achieve the above purpose, the utility model adopts the technical scheme that:

[0006] A building perpendicularity detection device comprises a fixed measuring ruler, a first level bubble is arranged on the fixed measuring ruler, a movable measuring ruler is rotatably connected to the bottom of the fixed measuring ruler, a second level bubble is arranged on the movable measuring ruler, a horizontal measuring ruler is movably connected to the side surface of the fixed measuring ruler, and a third level bubble is arranged on the horizontal measuring ruler.

[0007] In the scheme, when the perpendicularity of the common wall is detected, the fixed measuring scale and the movable measuring scale are rotated to the coincident position, and then the fixed measuring scale is abutted on the wall to directly measure; when the perpendicularity of the wall with high requirements or the wall with recess is detected, the movable measuring scale is rotated to be staggered with the position of the fixed measuring scale, and then the movable measuring scale and the fixed measuring scale are abutted on the wall to measure, the first bubble level and the second bubble level show the perpendicularity of the wall abutted by the fixed measuring scale and the movable measuring scale respectively, the detection precision is high, and the use range is wide.

[0008] Further, the bottom of the fixed measuring scale is movably connected with a rotating shaft, and the movable measuring scale is movably connected with the rotating shaft; a spring is sleeved on the rotating shaft, one end of the spring is abutted against a limiting plate at the end of the rotating shaft, and the other end of the spring is abutted against the inner wall of the fixed measuring scale; a limiting strip is arranged on the side of the fixed measuring scale close to the movable measuring scale, and a limiting groove is formed in the side of the movable measuring scale close to the fixed measuring scale along the length direction of the rod body, and the limiting strip is embedded in the limiting groove.

[0009] In the scheme, the limiting strip is embedded in the limiting groove to limit the fixed measuring scale and the movable measuring scale when the fixed measuring scale and the movable measuring scale are in the coincident state or the unfolded state, so that the fixed measuring scale and the movable measuring scale cannot be moved at will in the two states. The spring can make the limiting strip embedded in the limiting groove more stable through the extrusion effect, and the relative rotation of the fixed measuring scale and the movable measuring scale is not affected.

[0010] Further, a sliding key is fixedly connected to the outer surface of the rotating shaft, and a key groove is formed in the position corresponding to the sliding key in the shaft hole of the fixed measuring scale.

[0011] In the scheme, when the fixed measuring scale and the movable measuring scale are relatively rotated, the fixed measuring scale moves slightly along the rotating shaft to extrude the spring due to the protruding design of the limiting strip, and the movement direction of the fixed measuring scale is limited by the design of the sliding key, and the rotating shaft cannot be rotated relative to the fixed measuring scale.

[0012] Further, an ear plate is arranged at the end of the horizontal measuring scale, and the horizontal measuring scale is movably connected with the fixed measuring scale through the pin shaft penetrating the ear plate and the fixed measuring scale.

[0013] In the scheme, the design of the horizontal measuring scale can refer to whether the fixed measuring scale and the movable measuring scale are vertically arranged in the plane perpendicular to the wall to be detected when the perpendicularity is detected, so as to ensure the accuracy of the wall detection.

[0014] Further, the fixed measuring scale and the movable measuring scale are both rectangular groove structures; when the end of the fixed measuring scale far from the rotating shaft and the end of the movable measuring scale far from the rotating shaft rotate to the farthest distance, the slot directions of the two rectangular groove structures are consistent.

[0015] Further, the first bubble level is fixed in the rectangular groove structure of the fixed measuring scale by two fixed plates; the second bubble level is fixed in the rectangular groove structure of the movable measuring scale by two fixed plates.

[0016] Further, the horizontal measuring scale is a plate structure, the plate structure is the same as the side wall of the rectangular groove structure of the fixed measuring scale, and the horizontal measuring scale is located at the position where the side wall of the rectangular groove structure is missing when the horizontal measuring scale is retracted.

[0017] In the scheme, when the horizontal measuring scale is retracted, the whole device has small volume, flat surface, and is convenient to carry.

[0018] Further, the rotating shaft penetrates one end of the movable measuring scale and is connected with a limiting disc, the top and bottom of the limiting disc extend two sharp pointer parts, and the side of the movable measuring scale is provided with a line groove along the length direction of the rod body.

[0019] In the scheme, when a wall body has protrusion or depression in detection, the side of the fixed measuring scale and the movable measuring scale close to the wall body is not in the same vertical plane, at this time, the pointer part of the limiting disc edge cannot be pointed on the line groove, so that it is indicated that the wall body is not perpendicular; the indication result of the pointer part can be combined with the detection results of the second bubble level and the first bubble level to analyze the uneven condition of the wall body.

[0020] Further, the fixed measuring scale and the movable measuring scale are both made of aluminum alloy.

[0021] In the scheme, the aluminum alloy has high hardness and light weight, and is suitable for manufacturing rulers and other tools.

[0022] The beneficial effects of the utility model are as follows:

[0023] In the use of the building verticality testing device provided by this utility model, when testing the verticality of ordinary walls, the movable measuring ruler is rotated relative to the pivot until it coincides with the fixed measuring ruler. The limiting strip is then embedded in the limiting groove to limit both rulers. The fixed measuring ruler is then directly placed against the wall for measurement, making it convenient to use. For walls with high verticality requirements or those with concave sections, the movable measuring ruler is rotated to offset its position from the fixed measuring ruler and to be fully extended. Both the movable and fixed measuring rulers are then simultaneously placed against the wall for measurement. The first and second spirit levels will respectively indicate the verticality of the wall to which the fixed and movable measuring rulers are attached, providing high detection accuracy and a wide range of applications. The horizontal measuring ruler design allows for reference during verticality testing, ensuring the accuracy of the wall measurement by indicating whether the fixed and movable measuring rulers are vertically positioned within a plane perpendicular to the wall being tested.

[0034] As shown in Figure 1 and Figure 2 The building perpendicularity detection device can be applied to detect the perpendicularity of a wall in various scenes, and has high detection accuracy. Specifically, the building perpendicularity detection device comprises:

[0035] The fixed measuring scale 1, the first bubble level 8, the movable measuring scale 2, the second bubble level 9, the horizontal measuring scale 3, and the third bubble level 10 are provided.

[0036] The first bubble level 8 is arranged on the fixed measuring scale 1.

The horizontal measuring scale 3 is movably connected to the side surface of the fixed measuring scale 1, and the third bubble level 10 is arranged on the horizontal measuring scale 3.

[0037] As shown in Figure 3-5 The bottom of the fixed measuring scale 1 is movably connected to the shaft 4, and the movable measuring scale 2 is movably connected to the shaft 4. The spring 5 is sleeved on the shaft 4, one end of the spring 5 abuts against the limiting plate 41 at the end of the shaft 4, and the other end of the spring 5 abuts against the inner wall of the fixed measuring scale 1. The side of the fixed measuring scale 1 close to the movable measuring scale 2 is provided with the limiting strip 11, and the side of the movable measuring scale 2 close to the fixed measuring scale 1 is provided with the limiting groove 21 along the length direction of the rod body. The limiting strip 11 is embedded in the limiting groove 21. When the fixed measuring scale 1 and the movable measuring scale 2 are in the overlapping state or the unfolded state, the limiting strip 11 is embedded in the limiting groove 21 to limit the fixed measuring scale 1 and the movable measuring scale 2. The spring 5 can make the limiting strip 11 embedded in the limiting groove 21 more stable through the extrusion effect, and it does not affect the relative rotation of the fixed measuring scale 1 and the movable measuring scale 2.

[0038] The outer surface of the rotating shaft 4 is fixedly connected with a sliding key 42, and the shaft hole of the fixed measuring ruler 1 is provided with a key groove corresponding to the sliding key 42, and the sliding key 42 is slidably connected in the key groove. When the fixed measuring ruler 1 and the movable measuring ruler 2 rotate relative to each other, due to the protruding design of the limiting strip 11, the fixed measuring ruler 1 will move slightly along the rotating shaft 4 to press the spring 5, and the design of the sliding key 42 limits the moving direction of the fixed measuring ruler 1, and ensures that the rotating shaft 4 will not rotate relative to the fixed measuring ruler 1.

[0039] As shown in Figure 6 The end of the horizontal measuring ruler 3 is provided with an ear plate 31, and the horizontal measuring ruler 3 is movably connected with the fixed measuring ruler 1 through a pin shaft 6 penetrating the ear plate 31 and the fixed measuring ruler 1. The design of the horizontal measuring ruler 3 can refer to whether the fixed measuring ruler 1 and the movable measuring ruler 2 are vertically arranged in a plane perpendicular to the wall to be measured when the perpendicularity is detected, so as to ensure the accuracy of the wall detection.

[0040] The fixed measuring ruler 1 and the movable measuring ruler 2 are both rectangular groove structures; when the end of the fixed measuring ruler 1 away from the rotating shaft 4 and the end of the movable measuring ruler 2 away from the rotating shaft 4 rotate to the farthest distance, the slot directions of the two rectangular groove structures are consistent.

[0041] The first bubble level 8 is fixed in the rectangular groove structure of the fixed measuring ruler 1 through two fixed plates 7; and the second bubble level 9 is fixed in the rectangular groove structure of the movable measuring ruler 2 through two fixed plates 7.

[0042] The horizontal measuring ruler 3 is a plate structure, the plate structure is the same as the side wall of the rectangular groove structure of the fixed measuring ruler 1, and the horizontal measuring ruler 3 is located at the position where the side wall of the rectangular groove structure is missing when the horizontal measuring ruler 3 is retracted. The design of the whole device is small in size, flat in outer surface, and convenient to carry when the horizontal measuring ruler 3 is retracted.

[0043] As shown in Figure 7 The rotating shaft 4 penetrates one end of the movable measuring ruler 2 and is connected with a limiting disc 43, the top and bottom of the limiting disc 43 extend two sharp pointer parts; and a marking groove 22 is formed on the side surface of the movable measuring ruler 2 along the length direction of the rod body. When the wall has protrusions or depressions during detection, the side of the fixed measuring ruler 1 and the movable measuring ruler 2 close to the wall is not in the same vertical plane, at this time, the pointer part of the edge of the limiting disc 43 cannot point on the marking groove 22, so as to indicate that the wall is not perpendicular; the indication result of the pointer part can be combined with the detection results of the second bubble level 9 and the first bubble level 8 to analyze the unevenness of the wall.

[0044] The fixed measuring ruler 1 and the movable measuring ruler 2 are both made of aluminum alloy, which is high in hardness and light in quality, and is suitable for making rulers and other tools.

[0045] The working principle of the embodiment is as follows:

[0046] In use, when the verticality of a common wall is detected, the movable measuring scale 2 is rotated relative to the rotating shaft 4 to a position coinciding with the fixed measuring scale 1, the limiting strip 11 is embedded in the limiting groove 21 to limit the two, and then the fixed measuring scale 1 is directly abutted against the wall to directly perform the measurement, and at this time, the building verticality detection device is in the contracted state, and is convenient to use. When the verticality of a wall with high requirements or a wall with a concave situation is detected, the movable measuring scale 2 is rotated to be staggered with the position of the fixed measuring scale 1 and is fully unfolded, at this time, the building verticality detection device is in the unfolded state, and then the movable measuring scale 2 and the fixed measuring scale 1 are simultaneously abutted against the wall to perform the measurement, the first leveling bubble 8 and the second leveling bubble 9 will respectively show the verticality of the wall abutted by the fixed measuring scale 1 and the movable measuring scale 2, the detection precision is high, and the use range is wide. The design of the horizontal measuring scale 3 can refer to whether the fixed measuring scale 1 and the movable measuring scale 2 are vertically arranged in a plane perpendicular to the wall to be detected, so that the accuracy of the wall detection is ensured.
