Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a roof slope measuring angle instrument. Background Technology

[0002] The slope of a building roof is a key indicator for ensuring the quality of roof waterproofing. When constructing the slope layer, the slope is often controlled by a chalk line, which cannot guarantee that the slope fully meets the design requirements, and water accumulation on the roof often occurs.

[0003] A search revealed a utility model patent in China with patent publication number CN218628298U, which discloses a slope measuring device for roof inspection. The device includes a lifting mechanism with a top plate and a bottom plate at its upper and lower ends, respectively. A first lead screw and a second lead screw are rotatably mounted between the top and bottom plates via bearings. In use, the lifting mechanism moves the measuring mechanism closer to the roof slope for measurement, avoiding manual labor. A motor drives the first lead screw to rotate, and the second lead screw rotates synchronously and in the same direction as the first lead screw via a transmission belt, maintaining left-right balance during lifting. Simultaneously, the guide rod and support rod work together to support and guide the translation of the lifting frame, improving its stability and the stability of the measuring mechanism during measurement, thus avoiding errors and improving the accuracy of the measurement results. However, the device still has some shortcomings. For example, the transmission belt may loosen after use, potentially causing errors between the two lead screws and resulting in the lifting frame jamming, affecting the overall usability and reducing its practicality.

The slider 12 is slidably connected through and through a lifting rod 13. The lifting rod 13 has an installation groove and an opening. The installation groove is rotatably connected to a protractor 14. The opening is fixedly connected to a pointer 15. The threaded groove is used to install screw 1 5 or screw 2 10. The suction cup 3 is used to adhere to the roof surface. The positioning nail 4 is suitable for use on roof surfaces where the suction cup 3 cannot be used. The lifting rod 13, the protractor 14, etc. are used to measure the roof slope.

[0017] The fixing mechanism is installed on the lifting rod 13 and includes a second sliding groove. The second sliding groove is opened on the lifting rod 13 and is connected to the mounting groove. A second slider 18 is slidably connected in the second sliding groove. An anti-slip pad 19 is fixedly connected to the second slider 18. A spring is provided between the second slider 18 and the second sliding groove. A control block 20 is fixedly connected to the second slider 18.

The positioning pin 4 is placed on the roof, and the user holds the entire device, checking the level of the fixing rod 2 through the bubble level 11 and controlling its operation. The suction cup 3 is attached to the roof. By hand-tightening the screw 9 and nut 7, the clamping adjustment groove 6 deforms, clamping and fixing the adjusting block 8. This achieves clamping and fixing of the adjusting block 8, facilitating the fixation of the support column 1. The adjusting block 8 can rotate within the adjusting groove 6. When the bubble level 1... 1. After fixing rod 2 horizontally, clamp and fix adjusting block 8. Then slide lifting rod 13. Anti-slip rubber sleeve 22 increases friction, which can improve the friction and stability of lifting rod 13. Lifting rod 13 drives protractor 14 to descend. At this time, control block 20 controls slider 18 to move. Slider 18 compresses spring and drives anti-slip pad 19 to move, no longer limiting protractor 14. Now protractor 14 can be placed on the slope of the roof for measurement. After measurement, release control block 20. Spring rebound drives slider 18, control block 20 and anti-slip pad 19 to move, so that anti-slip pad 19 is placed on protractor 14 to limit and fix protractor 14. Then the whole device can be picked up to check the angle indicated by pointer 15.
