Description

Technical Field

[0001] This utility model relates to the field of building engineering measurement technology, and in particular to a device for measuring the tilt angle of building walls. Background Technology

[0002] Measuring the tilt angle of walls is a crucial step in building construction, final acceptance, and safety monitoring of existing buildings. Current tools for measuring wall tilt mainly include theodolites, laser levels, and traditional inclinometers.

[0003] When using the above technology, the following technical problems were found in the existing technology: In the existing technology, the degree of inclination of the wall is generally measured by plumb line, that is, the top of the plumb line is placed against the wall, and then the weight at the bottom of the plumb line is kept in a vertical state under the action of gravity. The angle between the plumb line and the wall is visually judged to determine whether the wall is tilted. However, this measurement method has many problems: Firstly, during the measurement process, if the wall is tilted and the measurement is taken on the side where the angle between the wall and the ground is obtuse, the weight may fall on the wall, making it impossible to measure the degree of tilt. The measurement results are not accurate enough. It is only possible to judge whether the wall is tilted by visual inspection, but it is impossible to measure the specific angle of tilt. When the tilt angle is small, it is impossible to judge whether the wall is tilted by visual inspection. Therefore, we have designed a building wall tilt angle measuring device to provide an alternative technical solution to the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for measuring the tilt angle of building walls to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A device for measuring the tilt angle of a building wall includes a measuring base. A measuring plate is rotatably connected to one end of the top of the measuring base. Arc-shaped guide blocks are fixed on both sides of one inner end of the measuring base. An arc-shaped measuring plate is slidably connected to the inner side of the arc-shaped guide blocks. The end of the arc-shaped measuring plate away from the arc-shaped guide blocks is fixed to the measuring plate. A positioning support plate one is rotatably connected to the top of one end of the measuring plate. A positioning support plate two is rotatably connected to the other inner end of the measuring base. One end of the positioning support plate two is rotatably connected to the positioning support plate one.

[0006] One side of the arc-shaped measuring plate is equipped with an angle scale for displaying the angle measured on the wall.

[0007] A spring is provided on one side of the inner side of the arc-shaped guide block, and a scale pointer is fixed on the inner side of the spring. The scale pointer is used to align with the angle scale ruler.

[0008] The positioning mechanism between the positioning support plate one and the positioning support plate two is used to limit the position of the measuring plate. The positioning mechanism includes a limiting gear, a U-shaped block, a meshing plate, an L-shaped plate and a spring. One side of the positioning support plate one passes through the positioning support plate two and is fixed with the limiting gear. One side of the positioning support plate two is slidably connected with the meshing plate, and one end of the meshing plate is meshed with the limiting gear.

[0009] Among them, a U-shaped block is fixed on one side of the positioning support plate two near one end of the positioning support plate one, and an L-shaped plate is slidably connected to the inner side of the U-shaped block. One end of the L-shaped plate passes through the U-shaped block and is fixedly connected to the meshing plate.

[0010] A spring is fitted onto the outer side of the L-shaped plate and the inner side of the U-shaped block. One end of the spring is fixed to the U-shaped block, and the other end of the U-shaped block is fixed to the L-shaped plate.

[0011] The measuring base has reset slots on both sides of the other end of its top, and the top of the measuring plate is slidably connected to the reset slots.

[0012] The measuring plate has two slots on its top and two sides, and the measuring base has guide grooves on both sides inside. An L-shaped guide block is slidably connected to the inside of the guide groove, and one end of the L-shaped guide block passes through the measuring base and is slidably connected to the slot.

[0013] The guide groove is equipped with a reset block, one end of which is fixed to the L-shaped guide block, and the other end of which is fixed to the measuring base.

[0014] A level is mounted on one side of the top of the measuring base. It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model ensures the reliability of the horizontal reference of the measuring base through the level, avoiding errors caused by reference offset. The sliding cooperation between the arc-shaped guide block and the arc-shaped measuring plate makes the tilt angle conversion smoother. The close contact between the angle scale and the scale pointer realizes the quantitative reading of the angle, replacing the traditional visual method, and can accurately capture even the slight tilt angle. At the same time, the rigid meshing between the limit gear and the meshing plate in the positioning mechanism can stably lock the measuring angle and prevent the angle from shifting during the reading process. The L-shaped guide block and the locking hole enable the measuring plate to be quickly limited and unlocked. The pull-type design of the L-shaped plate in the positioning mechanism simplifies the angle fine-tuning operation. The entire measurement process can be completed without complicated tools. The level adjustment of the measuring base relies on an intuitive level, which lowers the operation threshold. In addition, the overall structure of the device is compact. The linkage design of the arc component and the positioning support plate can be adapted to walls with different inclination directions, avoiding the problem that traditional plumb lines cannot measure due to the limitation of the weight's landing point.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figure 1-7This utility model provides a technical solution: a building wall tilt angle measuring device, including a measuring base 1, a measuring plate 2 rotatably connected to one end of the top of the measuring base 1, a level 8 mounted on one side of the top of the measuring base 1, arc-shaped guide blocks 6 fixed on both sides of one end of the inner side of the measuring base 1, an arc-shaped measuring plate 7 slidably connected to the inner side of the arc-shaped guide block 6, the end of the arc-shaped measuring plate 7 away from the arc-shaped guide block 6 fixed to the measuring plate 2, a positioning support plate 4 rotatably connected to the top of one end of the measuring plate 2, a positioning support plate 5 rotatably connected to the other end of the inner side of the measuring base 1, and one end of the positioning support plate 5 rotatably connected to the positioning support plate 4. First, place the measuring base 1 on a level surface on one side of the wall. Observe the level 8 mounted on the top side of the measuring base 1 and adjust the position of the base until the level 8 shows a horizontal state to ensure the stability and accuracy of the measurement benchmark and provide a reliable horizontal reference for subsequent angle measurement. Rotating the measuring plate 2 causes the side of the measuring plate 2 away from the rotating connection end to fit tightly against the wall to be measured. The tilt state of the wall will be transmitted to the measuring plate 2 through the contact surface, causing the measuring plate 2 to form a deflection angle that is consistent with the tilt angle of the wall. The positioning support plate 4, which is rotatably connected to one end of the measuring plate 2, will rotate relative to the positioning support plate 5, which is rotatably connected to the other end of the measuring base 1, as the measuring plate 2 rotates. The included angle formed by the two changes synchronously with the deflection angle of the measuring plate 2. The angle is locked by the limiting gear 10 and the meshing plate 12. An angle scale 9 for measuring the angle of the wall is mounted on one side of the arc-shaped measuring plate 7. A spring 17 is provided on one side of the inner side of the arc-shaped guide block 6. A scale pointer 18 is fixed on the inner side of the spring 17. The scale pointer 18 is used to align with the angle scale 9. When the measuring plate 2 is rotated so that the side of the measuring plate 2 away from the rotating connection end is in close contact with the wall to be measured, the tilt state of the wall will be transmitted to the measuring plate 2 through the contact surface, causing the measuring plate 2 to form a deflection angle consistent with the tilt angle of the wall. Since the end of the measuring plate 2 away from the arc-shaped guide block 6 is fixedly connected to the arc-shaped measuring plate 7, and the arc-shaped measuring plate 7 is slidably nested inside the arc-shaped guide block 6 fixed on both sides of the inner side of the measuring base 1, when the measuring plate 2 rotates, it will synchronously drive the arc-shaped measuring plate 7 to slide along the inner trajectory of the arc-shaped guide block 6, thereby realizing the transformation of the tilt angle into arc-shaped motion. A positioning mechanism for limiting the measuring plate 2 is provided between positioning support plate 1 4 and positioning support plate 2 5. The positioning mechanism includes a limiting gear 10, a U-shaped block 11, a meshing plate 12, an L-shaped plate 13 and a spring 17. One side of positioning support plate 1 4 passes through positioning support plate 2 5 and is fixed with the limiting gear 10. One side of positioning support plate 2 5 is slidably connected with the meshing plate 12, and one end of the meshing plate 12 is meshed with the limiting gear 10. A U-shaped block 11 is fixed on one side of the positioning support plate 2 5 near one end of the positioning support plate 1 4. An L-shaped plate 13 is slidably connected to the inner side of the U-shaped block 11. One end of the L-shaped plate 13 passes through the U-shaped block 11 and is fixedly connected to the meshing plate 12. A spring 17 is sleeved on the outer side of the L-shaped plate 13 and inside the U-shaped block 11. One end of the spring 17 is fixed to the U-shaped block 11, and the other end of the U-shaped block 11 is fixed to the L-shaped plate 13. One side of the positioning support plate 4 passes through the positioning support plate 5 and is fixed with the limiting gear 10. When the positioning support plate 4 and the positioning support plate 5 rotate relative to each other, the limiting gear 10 will rotate synchronously with the positioning support plate 4. The meshing plate 12, which is slidably connected to one side of the positioning support plate 2 5, always maintains a meshing state with the limiting gear 10 under the preload of the spring 17 inside the U-shaped block 11. The spring 17 is sleeved on the outside of the L-shaped plate 13, with one end fixed to the U-shaped block 11 and the other end fixed to the L-shaped plate 13. The L-shaped plate 13 is slidably connected to the inside of the U-shaped block 11 and one end is fixed to the meshing plate 12. The elastic force of the spring 17 is transmitted to the meshing plate 12 through the L-shaped plate 13, so that it is tightly engaged in the tooth groove of the limiting gear 10, thereby achieving real-time limiting of the rotation angle of the positioning support plate 1 4. If the angle of the measuring plate 2 needs to be finely adjusted, the L-shaped plate 13 can be pulled outward to disengage the meshing plate 12 from the limiting gear 10. At this time, the position of the measuring plate 2 can be freely adjusted. After the adjustment is in place, the L-shaped plate 13 is released. Under the action of the spring 17, the meshing plate 12 re-engages with the limiting gear 10 to complete the angle locking and ensure that the angle remains stable during the measurement process. An angle scale 9 is mounted on one side of the arc-shaped measuring plate 7. The scale slides synchronously along the arc-shaped guide block 6 with the arc-shaped measuring plate 7. A spring 17 is provided in the mounting groove on one side of the inner side of the arc-shaped guide block 6. The scale pointer 18 fixed inside the spring 17 is always in close contact with the surface of the angle scale 9 under the action of the spring 17, forming a stable reading reference. When the measuring plate 2 drives the arc measuring plate 7 to slide to a position that matches the tilt angle of the wall, the position of the angle scale 9 is fixed. At this time, the value on the angle scale 9 pointed to by the scale pointer 18 is the tilt angle of the wall to be measured, thus realizing the precise quantitative reading of the tilt angle. Both sides of the other end of the measuring base 1 are provided with reset grooves 14, and the top of the measuring plate 2 is slidably connected to the reset grooves 14. Both sides of the top of the measuring plate 2 are provided with locking holes 3, and both sides of the inside of the measuring base 1 are provided with guide grooves. An L-shaped guide block 15 is slidably connected to the inside of the guide groove. One end of the L-shaped guide block 15 passes through the measuring base 1 and is slidably connected to the locking hole 3. A reset block 16 is assembled inside the guide groove. One end of the reset block 16 is fixed to the L-shaped guide block 15, and the other end of the reset block 16 is fixed to the measuring base 1. In the initial state, the top of the measuring plate 2 and the reset grooves 14 on both sides of the other end of the top of the measuring base 1 are in sliding contact. At the same time, the reset block 16 in the guide groove inside the measuring base 1 is in a natural state. The L-shaped guide block 15 fixed at one end passes through the measuring base 1 and forms a sliding engagement with the locking holes 3 on both sides of the top of the measuring plate 2 under the force of the reset block 16, thereby realizing the initial positioning of the measuring plate 2. Manually pull the L-shaped guide block 15 to slide along the guide groove so that one end of it disengages from the locking hole 3 of the measuring plate 2, thereby releasing the initial limit on the measuring plate 2. At this time, the measuring plate 2 can rotate freely around the rotating connection point at the top of the measuring base 1 to perform the measurement. After the measurement is completed, pull the L-shaped plate 13 to disengage the meshing plate 12 from the limiting gear 10, and rotate the measuring plate 2 back to the initial position. At this time, the reset block 16 in the guide groove inside the measuring base 1 drives the L-shaped guide block 15 to reset, so that it is re-engaged into the card hole 3 of the measuring plate 2, completing the reset of the device and facilitating the next measurement.

[0021] The usage process of the building wall tilt angle measuring device provided by this utility model is as follows: Place the measuring base 1 on a horizontal surface next to the wall, observe the level 8 mounted on it, and adjust the position of the base until the level 8 shows horizontal, providing a stable reference for measurement; In the initial state, the reset block 16 inside the measuring base 1 drives the L-shaped guide block 15 to engage with the card hole 3 of the measuring plate 2. Combined with the fit between the measuring plate 2 and the reset groove 14, the initial limit of the measuring plate 2 is achieved. Pull the L-shaped guide block 15 to disengage it from the card hole 3, release the limit of the measuring plate 2, rotate the measuring plate 2 to make it fit tightly against the wall, the tilt angle of the wall is transmitted to the measuring plate 2 through the fitting surface, causing it to deflect around the rotation point of the measuring base 1. Simultaneously, the arc-shaped measuring plate 7 fixed by the measuring plate 2 slides along the arc-shaped guide block 6, and the positioning support plate 1 4 and the positioning support plate 2 5 also change their relative angles as the measuring plate 2 rotates. The limiting gear 10 on the positioning support plate 4 rotates with it. The meshing plate 12 on the side of the positioning support plate 5, under the pre-tightening force of the spring 17 in the U-shaped block 11, meshes with the limiting gear 10 through the force transmitted by the L-shaped plate 13, locking the current angle in real time. If fine adjustment is required, pull the L-shaped plate 13 to disengage the meshing plate 12 from the gear. After adjustment, release it to relock. At this time, the angle scale 9 on the arc measuring plate 7 slides to the corresponding position. The scale pointer 18 fixed by the spring 17 in the arc guide block 6 is closely attached to the scale. The value pointed to by the pointer is the tilt angle of the wall. After the measurement is completed, pull the L-shaped plate 13 to disengage the gear and rotate the measuring plate 2 back to the initial position. The reset block 16 drives the L-shaped guide block 15 to automatically reset and lock into the card hole 3, completing the storage of the device and preparing it for the next use.
