Description

Technical Field

[0001] This utility model relates to the field of flatness detection, specifically a device for detecting the flatness of building walls. Background Technology

[0002] A wall flatness tester is a tool used to check whether walls and tiles are flat and vertical, and whether wall and floor joists are level and flat. The tester is one of the most frequently used wall inspection tools in home decoration supervision. However, when using the current wall flatness tester, the length of the tester is difficult to adjust. When inspecting higher parts of the wall, the tester needs to be suspended in the air. At this time, the lower end of the tester is separated from the ground, making it difficult to accurately keep the lower end parallel to the ground, thus causing errors in the inspection.

[0003] Therefore, we propose a wall flatness detection device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a house wall flatness detection device, including a base, on which a storage groove is provided, and both ends of the storage groove extend through the base, and a detection component is installed on the storage groove.

[0006] The detection component includes a motor, which is slidably mounted on the front end face of the base via a slide rail. The front end of the base has an opening, and the rear end of the motor output shaft is fixedly connected to a first drive shaft. The rear end of the first drive shaft passes through the opening and the base, extends into the storage slot, and is fixedly connected to the front end face of the rectangular detection box. A bidirectional motor is fixedly installed at the bottom center of the rectangular detection box. The lower ends of both ends of the bidirectional motor output shaft are mechanically linked to a second drive shaft. The left end of the second drive shaft is rotatably connected to the left end of the rectangular detection box, and the right end of the second drive shaft passes through the rectangular detection box and is fixedly connected to a screw. Both screws are threaded through the rectangular detection plate, and the upper end face of the rectangular detection plate is at the same horizontal height as the upper end face of the rectangular detection box.

[0007] As a preferred technical solution of this utility model, the right ends of the two screws are symmetrically rotated and installed on the left end face of the limiting baffle.

[0008] As a preferred embodiment of this utility model, both ends of the bidirectional motor output shaft are fixedly connected to worm gears, and the lower end of the worm gears is engaged with worm wheels. The two worm wheels are respectively fixedly mounted on two second drive shafts.

[0009] As a preferred technical solution of this utility model, the second drive box and the first drive box are symmetrically embedded and fixedly installed on the front and rear ends of the top left end of the storage slot, and the first drive box is located in front of the second drive box. The first cylinder and the second cylinder are respectively fixedly installed on the right end face of the first drive box and the second drive box.

[0010] The first cylinder and the second drive output end are respectively fixedly installed with a first drive block and a second drive block, which are symmetrically installed on the front and rear end faces of the rectangular drive box.

[0011] As a preferred technical solution of this utility model, the first drive box and the second drive box are both provided with drive ports on one end face close to each other.

[0012] A hollow drive rod is fixedly installed on the rear end face of the first drive block, and a rotating shaft is fixedly installed on the front end face of the second drive block. The hollow drive rod and the other end of the rotating shaft pass through two drive ports respectively and are symmetrically rotated and installed at the front and rear ends of the rectangular drive box.

[0013] As a preferred technical solution of this utility model, the first drive shaft passes through the hollow drive rod, and a slider is rotatably fixed on the first drive shaft. The side end face of the slider slides and fits against the inner wall of the base in a horizontal direction.

[0014] The beneficial effects of this utility model are:

[0015] 1. When using this type of house wall flatness detection device, first start the motor to rotate the rectangular detection box 90°. Then start the first and second cylinders to move the rectangular detection box to the left, so that the upper surface of the rectangular detection box is in contact with the bottom of the house wall. Then start the bidirectional motor to drive the screw, which in turn moves the rectangular detection plate up and down. Observe whether there is a gap between the rectangular detection plate and the house wall. If there is a gap or the movement path of the rectangular detection plate is blocked by the house wall, it indicates that the house wall is tilted.

[0016] 2. In this type of house wall flatness testing device, the upper surface of the rectangular testing plate and the upper surface of the rectangular testing box are at the same horizontal level. With this design, the flatness of the house wall can be tested by moving the rectangular testing plate on the screw: whether the bottom of the house wall that the upper surface of the rectangular testing plate passes through and the bottom surface of the house wall that is in contact with the upper surface of the rectangular testing box are on the same horizontal plane, thereby realizing the testing of the flatness of the house wall.

[0017] This invention can detect whether the walls of a house are flat and can automatically adjust the detection height to accommodate walls of different sizes. It also has an automatic storage function, making storage and transportation more convenient. Attached Figure Description

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example: Figure 1-2 As shown, the present invention provides a wall flatness detection device for houses, including a base 1. Four brakeable universal wheels are installed in a rectangular array at the lower end of the base 1. A storage groove 3 is provided on the base 1, and both ends of the storage groove 3 pass through the base 1. A detection component 2 is installed on the storage groove 3.

[0027] The detection component 2 includes a motor 201, which is slidably mounted on the front end face of the base 1 via a slide rail. The front end of the base 1 has an opening. The rear end of the output shaft of the motor 201 is fixedly connected to a first drive shaft 202. The rear end of the first drive shaft 202 passes through the opening and the base 1 and extends into the storage groove 3, and is fixedly connected to the front end face of the rectangular detection box 205. A bidirectional motor 216 is fixedly installed in the middle of the bottom of the rectangular detection box 205. The lower ends of the front and rear ends of the output shaft of the bidirectional motor 216 are mechanically linked to a second drive shaft 214. The left end of the second drive shaft 214 is rotatably connected to the left end of the rectangular detection box 205. The right end of the second drive shaft 214 passes through the rectangular detection box 205 and is fixedly connected to a screw 209. Both screws 209 are threaded through the rectangular detection plate 208.

[0028] The upper surface of the rectangular detection plate 208 and the upper surface of the rectangular detection box 205 are at the same horizontal level. With this design, the flatness of the house wall is detected by moving the rectangular detection plate 208 on the screw 209. This allows the bottom of the house wall that the upper surface of the rectangular detection plate 208 passes through to be on the same horizontal plane as the upper surface of the rectangular detection box 205, thereby enabling the detection of the flatness of the house wall.

[0029] The utility model can be moved to the side of the house wall by means of the casters, and then the flatness of the house wall can be detected by the detection component 2.

[0030] In this embodiment, as Figure 3-4 As shown, the right ends of the two screws 209 are symmetrically rotated and installed on the left end face of the limiting baffle 210.

[0031] The rectangular detection plate 208 can be limited by the limiting baffle 210 to prevent the rectangular detection plate 208 from moving too much and falling off the screw 209.

[0032] The output shaft of the bidirectional motor 216 is fixedly connected to both ends of a worm gear 215. The lower end of the worm gear 215 is engaged with a worm wheel 219. The two worm wheels 219 are respectively fixedly mounted on two second drive shafts 214.

[0033] By starting the bidirectional motor 216, the bidirectional motor 216 can drive the worm 215 to rotate. The rotating worm 215 can drive the second drive shaft 214 to rotate through the worm wheel 219, which in turn can drive the screw 209 to rotate.

[0034] The storage slot 3 has a second drive box 206 and a first drive box 204 symmetrically embedded and fixedly installed on the top left side and the front and rear ends. The first drive box 204 is located in front of the second drive box 206. The first cylinder 211 and the second cylinder 218 are fixedly installed on the right side inside the first drive box 204 and the second drive box 206, respectively.

[0035] The first cylinder 211 and the second drive output end are respectively fixedly installed with the first drive block 212 and the second drive block 217. The first drive block 212 and the second drive block 217 are symmetrically installed on the front and rear end faces of the rectangular drive box.

[0036] By activating the first cylinder 211 and the second cylinder 218, the first drive block 212 and the second drive block 217 can be driven, thereby automatically adjusting the position of the rectangular detection box 205. When detecting the flatness of the house wall, the upper surface of the rectangular detection box 205 needs to be in contact with the bottom of the house wall.

[0037] The first drive box 204 and the second drive box 206 are both provided with drive ports 207 on one end face close to each other;

[0038] A hollow drive rod 213 is fixedly installed on the rear end face of the first drive block 212, and a rotating shaft is fixedly installed on the front end face of the second drive block 217. The hollow drive rod 213 and the other end of the rotating shaft pass through two drive ports 207 respectively, and are symmetrically rotated and installed at the front and rear ends of the rectangular drive box.

[0039] By starting the motor 201, the motor 201 can drive the first drive shaft 202 to rotate, which in turn can drive the rectangular detection box 205 to rotate. At this time, the hollow drive rod 213 and the rotating shaft rotate with the rectangular detection box 205.

[0040] The first drive shaft 202 passes through the hollow drive rod 213. A slider 203 is rotatably fixed on the first drive shaft 202. The side end face of the slider 203 slides and fits against the inner wall of the base 1 in the horizontal direction.

[0041] With the above design, when the rectangular detection box 205 moves horizontally, the slider 203 can slide horizontally within the first drive box 204, thereby improving the stability of the motor 201 installation.

[0042] Detailed implementation method: In use, first start the motor 201 to rotate the rectangular detection box 205 by 90°. Then start the first cylinder 211 and the second cylinder 218 to move the rectangular detection box 205 to the left, so that the upper surface of the rectangular detection box 205 is in contact with the bottom of the house wall. Then start the bidirectional motor 216 to drive the screw 209, which in turn moves the rectangular detection plate 208 up and down. Observe whether there is a gap between the rectangular detection plate 208 and the house wall. If there is a gap or the movement path of the rectangular detection plate 208 is blocked by the house wall, it indicates that the house wall is tilted.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
