Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a stair drip line trowel. Background Art

[0002] With the rapid development of the construction industry, the requirements for professional and efficient construction techniques and tools are increasing. Especially in residential, commercial and public buildings, stairs are important passages connecting upper and lower spaces. The quality of their waterproof details directly affects the service life and maintenance cost of the building. As a key waterproof detail measure, the construction quality and efficiency of the stair drip line directly affect the durability and living comfort of the building.

[0003] In the past, in the construction of stair drip lines, manual trimming with a general trowel was generally used, which was not only time-consuming and labor-intensive, but also difficult to achieve standardized and refined production of drip lines. Due to the lack of specialized tools, workers need to rely on experience to control the depth and width of the grooves, which is not only a large workload, but also difficult to ensure that the size of each drip line is uniform and the lines are smooth, which can easily affect the overall aesthetics of the building and the stability of its waterproof performance. Therefore, the market is in urgent need of a professional tool that can improve the efficiency and quality of stair drip line construction to meet the high-standard construction requirements of modern buildings.

[0028] refer to Figure 1-Figure 4, this embodiment provides a stair drip line trowel, which includes a trowel plate 1, a rotating assembly 2, a handle connecting rod 3 and a handle 4. In this embodiment, the trowel plate 1, the rotating assembly 2, the handle connecting rod 3 and the handle 4 are arranged in sequence from top to bottom. Specifically, the trowel plate 1 is made of high-strength steel, with a size of 150mm×50mm×30mm×0.5mm. At the same time, a groove 5 with a size of 10mm×10mm is provided on the trowel plate 1 to ensure that the shape and depth of the drip line can be accurately controlled during plastering. It is worth noting that inclined blocks 9 are provided on both sides of the inner part of the groove 5, and the angle between the groove 5 and the inclined block 9 is not greater than 5°, which helps the plastering material to flow smoothly, while reducing the accumulation of mortar in the groove, making it easy to clean. Furthermore, the inner wall of the groove 5 and the outer surface of the inclined block 9 are provided with a micro-texture layer, which increases the friction coefficient of the inner wall of the groove 5 and the outer surface of the inclined block 9, which not only helps to improve the stability during the plastering operation and prevent the trowel from slipping, but also makes the drip line smoother and more uniform, thereby improving the construction quality and aesthetics.

[0029] In this embodiment, the lower end of the wiper 1 is connected to the upper end of the handle connecting rod 3 through the rotating assembly 2, and the lower end of the handle connecting rod 3 is connected to the handle 4, that is, the setting of the rotating assembly 2 can realize the flexible adjustment of the angle of the wiper 1, which greatly improves the flexibility and efficiency of the construction. Specifically, the end of the wiper 1 facing the handle 4 is provided with a rounded corner, and the angle of the rounded corner is not greater than 90°, and the outer surface of the handle 4 is provided with anti-slip grooves. In other words, the setting of the anti-slip grooves can increase the friction between the construction personnel's hands and the handle 4, so that it can maintain a stable grip even under wet or sweaty conditions, thereby reducing the risk of slipping during operation and improving the continuity and safety of the operation. At the same time, the setting of the rounded corners can reduce accidental scratches by construction personnel during use, thereby improving the comfort and safety of use.

[0030] In this embodiment, the rotating assembly 2 includes an upper rotating ball 7 and a lower rotating ball 8, wherein the upper rotating ball 7 is fixedly connected to the lower end of the wiper 1, and the lower rotating ball 8 is fixedly connected to the upper end of the handle connecting rod 3, and the upper rotating ball 7 is arranged at the upper end of the lower rotating ball 8, and the upper rotating ball 7 and the lower rotating ball 8 are in contact with each other. In other words, the angle between the wiper 1 and the handle connecting rod 3 can be adjusted by rotating the upper rotating ball 7 and the lower rotating ball 8. Further, the outer side of the upper rotating ball 7 and the lower rotating ball 8 are connected to the rotating rod 6 through the ball connecting rod 12, and the rotating rod 6 is arranged on the side of the upper rotating ball 7 and the lower rotating ball 8, and the outer end of the rotating rod 6 is provided with a rotating button 13, and the rotating button 13 is arranged outside the rotating assembly 2. At the same time, both sides of the upper rotating ball 7 and the lower rotating ball 8 are provided with auxiliary cavities 14, and the side facing outward inside the auxiliary cavity 14 is provided with a slide groove 11, and both ends of the rotating rod 6 pass through the auxiliary cavity 14, and the end of the rotating rod 6 is arranged inside the slide groove 11 through the sliding block 10. Further, a spring lock is arranged inside the rotating rod 6, and the control shaft of the spring lock is connected to the rotating button 13, and the two ends of the spring lock are connected to the sliding blocks 10 on both sides. That is to say, when adjusting the angle between the wiper plate 1 and the handle connecting rod 3, the rotating button 13 is rotated to open the spring lock, and then the wiper plate 1 or the handle connecting rod 3 can be rotated arbitrarily, and after rotating to a suitable angle, the rotating button 13 is directly rotated to lock the sliding block 10 inside the slide groove 11 through the spring lock. Specifically, during the rotation process, the rotation of the upper rotating ball 7 or the lower rotating ball 8 will drive the rotating rod 6 to rotate, and then drive the sliding block 10 to slide on the slide groove 11, that is, the sliding of the sliding block 10 on the slide groove 11 can change the angle between the upper rotating ball 7 and the lower rotating ball 8. It is worth noting that the spring lock here is composed of a spring, a connecting shaft and a control shaft, wherein the connecting shaft and the control shaft are connected by a spring, and the connecting shaft and the sliding block 10 are connected at the same time, and it can lock the sliding block 10 and the slide groove 11. The locking method here can be the existing buckle locking method, which is not fixed.
