Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to a stair scraper for building material decoration and fitment. Background Technique
[0002] A stair is a component used for vertical traffic between floors in a building, and is used for traffic connection between floors and when there is a large height difference. Stairs are also provided in multi-storey and high-rise buildings where elevators and escalators are used as the main means of vertical traffic. Although elevators are used as the main means of vertical transportation in high-rise buildings, stairs are still reserved for escape in case of fire.
[0003] Many existing stairs are made of cement. The upper surface of the stairs made of cement is relatively smooth, so pedestrians are likely to fall when stepping on the stairs. Therefore, some workers install metal anti-slip strips on the stair surface. However, installing metal anti-slip strips increases the cost, and the metal anti-slip strips are easy to fall off from the stairs. So, existing workers use a scraper to scrape anti-slip grooves on the stairs to achieve the anti-slip effect. However, because the scraper is very easy to cause the depth of the scraped anti-slip grooves to be uneven during use, the aesthetics are affected. Content of the Utility Model

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.
[0024] Please refer to Figures 1 - 3 , the present utility model provides a staircase scraper for building material decoration, which includes a housing 1. Two groups of operating arms 2 are fixedly connected to the top end of the outer wall of the housing 1. The housing 1 is driven to move on the surface of the staircase by grasping the two groups of operating arms 2. A moving seat 3 is slidably connected to the inner wall of the top end of the housing 1. Three groups of card slots 6 are formed in the inner wall of the moving seat 3. The card slots 6 are inserted into the limiting slots 13. The insertion between the two enables the limiting column 4 to move according to the actual depth of the groove opened, and fixes the adjusted position. Three groups of limiting columns 4 penetrate and are slidably connected to the inner wall of the housing 1. Fixed plates 5 are fixedly connected to the top ends of the outer walls of the three groups of limiting columns 4. By the fixed plates 5, the three groups of limiting columns 4 are simultaneously pushed to move downward synchronously on the inner wall of the housing 1. A fixed block 7 is elastically connected to the inner wall of the housing 1 through a limiting spring 8. The fixed block 7 is slidably connected to the inner wall of the housing 1. A cavity that fits the fixed block 7 is formed in the inner wall of the housing 1, so that the fixed block 7 can move up and down on the inner wall of the housing 1. The fixed block 7 is fixedly connected to the outer wall of the limiting column 4. One end of the limiting spring 8 is fixedly connected to the top end of the inner wall of the housing 1, and the other end of the limiting spring 8 is fixedly connected to the top end of the outer wall of the fixed block 7. When the limiting column 4 is pressed to move downward on the inner wall of the housing 1, the fixed block 7 will move synchronously with it. At this time, the limiting spring 8 will produce a tensile deformation. After the limiting column 4 is clamped by the moving seat 3 at this time, the three groups of limiting columns 4 will be elastically forced downward by the limiting spring 8 to clamp and tighten the limiting slots 13 of the limiting column 4 with the card slots 6 in the moving seat 3, preventing the moving seat 3 from moving.
[0025] Further, a moving block 9 is inserted at the bottom end of the outer wall of the limiting post 4. The three moving blocks 9 move along with the housing 1, so as to dig out grooves on the surface of the stairs. The material used for the moving block 9 is made of hard rubber. An inserting block 11 is elastically connected to the inner wall of the moving block 9 through a return spring 10. One end of the return spring 10 is fixedly connected to the inner wall of the moving block 9, and the other end of the return spring 10 is fixedly connected to the left outer wall of the inserting block 11. When it is necessary to replace the moving block 9, the inserting block 11 is toggled to disengage from the jack 12 on the outer wall of the limiting post 4, so that the moving block 9 disengages from the outer wall at the bottom end of the limiting post 4. When the inserting block 11 is released, it will be restored to its initial position under the elastic action of the return spring 10. An inserting hole 12 is provided on the outer wall at the bottom end of the limiting post 4. The inserting block 11 is slidably connected to the inner wall of the moving block 9, and the inserting block 11 is inserted into the inserting hole 12. The connection between the two fixes the position of the moving block 9, preventing the moving block 9 from disengaging from its inner wall during use. A plurality of limiting grooves 13 are provided on the outer wall of the limiting post 4.
[0026] In the present utility model, during use, when it is necessary to scrape and level the stairs, the operating arm 2 is used to drive the housing 1 to move on the surface of the stairs so as to level the stairs. At this time, the three limiting posts 4 can be driven to move the moving blocks 9 at their bottom ends inside the housing 1 by pressing the fixing plate 5, and the adjustment is made according to the depth of the groove to be dug. When adjusted to the appropriate position, the moving seat 3 is moved so that the card slots 6 on its surface are inserted into the limiting grooves 13 at the current positions of the three limiting posts 4. At this time, the fixing plate 5 is released, and the fixing blocks 7 on the outer walls of the three limiting posts 4 and the limiting springs 8 at the top end of the housing 1 will undergo tensile deformation, so as to restore the position of the limiting posts 4 after movement to the initial position. At this time, due to the engagement of the card slots 6 and the limiting grooves 13, the limiting posts 4 will press the position of the moving seat 3 under the elastic action of the limiting springs 8.
[0027] Meanwhile, when it is necessary to replace and clean the moving block 9 during long-term use, the inserting block 11 inside the moving block 9 can be pulled to disengage from the jack 12 on the outer wall at the bottom end of the limiting post 4. At this time, the moving block 9 can be directly taken out from the bottom end of the outer wall of the limiting post 4, so as to clean or replace the moving block 9.
[0028] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
