[0027] Embodiment 1
[0028] Referring to Figures 1-6 In the first embodiment of the present application, the floor screed comprises a main body assembly 100, which comprises an upper flat plate 101, a fixed long plate 102 fixed on one side of the upper flat plate 101, a fixed short plate 103 fixed on the other end of the upper flat plate 101, a first rotating plate 104 rotatably connected on one side of the fixed short plate 103, and a second rotating plate 105 rotatably connected on one side of the fixed long plate 102. The positions of the upper flat plate 101, the fixed long plate 102 and the fixed short plate 103 are fixed, while the relative positions of the first rotating plate 104 and the second rotating plate 105 can be changed, thereby changing the shape of the floor screed. The materials of the above components are all aluminum alloy.
[0029] After the mortar is placed in the designated position, the mortar needs to be dispersed, at this time the first rotating plate 104 and the second rotating plate 105 are in a parallel state, so that the bottom of the floor screed ruler has an inclined slope, and the fixed long plate 102 and the second rotating plate 105 jointly form a sharp end, the sharp end can concentrate power and accurately insert the mortar, so that the larger mortar is broken into smaller particles, so that the mortar is more easily dispersed, and a good foundation is laid for the subsequent troweling work. At the same time, during construction, there may be some gaps or uneven areas on the ground, the sharp end can extend into these gaps to bring out the mortar therein and disperse it to fill the surrounding low-lying areas, which helps to improve the flatness and overall consistency of the ground.
[0030] Then the ground is scraped flat, the positions of the first rotating plate 104 and the second rotating plate 105 are adjusted, so that they are perpendicular to each other, and the fixed long plate 102 is perpendicular to the second rotating plate 105, and the first rotating plate 104 is collinear with the fixed short plate 103, at this time the bottom surface of the floor screed ruler is flat, and the scraping is completed.
[0031] The adjusting assembly 200 is located on the first rotating plate 104 and includes an adjusting piece 201 for adjusting the positions of the first rotating plate 104 and the second rotating plate 105, thereby changing the shape of the bottom surface of the floor screed ruler to meet the needs of different construction stages.
[0032] The adjusting piece 201 includes a fixed column 2011 fixed to the second rotating plate 105, a sliding groove 104-1 is formed in the first rotating plate 104, the fixed column 2011 slides in the sliding groove 104-1, and a sliding groove 104-3 is formed in the first rotating plate 104, one end of the second rotating plate 105 is slidable in the sliding groove 104-3.
[0033] When the first rotating plate 104 and the second rotating plate 105 are perpendicular to each other, the fixed column 2011 is located at the lowest position in the sliding groove 104-3.
[0034] When the first rotating plate 104 and the second rotating plate 105 are no longer perpendicular to each other, the second rotating plate 105 is pushed to move, one end of the second rotating plate 105 slides in the sliding groove 104-3, and the fixed column 2011 slides in the sliding groove 104-1 and slides upward, the first rotating plate 104 and the second rotating plate 105 will gradually be collinear, and the fixed long plate 102 and the second rotating plate 105 will gradually jointly form a sharp end, until the fixed column 2011 is located at the highest position in the sliding groove 104-3.
[0035] Since one end of each of the first rotating plate 104 and the second rotating plate 105 is fixed in position, when the position of the second rotating plate 105 sliding in the sliding groove 104-3 is locked, the relative position between the two is fixed, so that the shape of the entire screed ruler is determined.
[0036] Embodiment 2
[0037] Referring to Figures 3-6 For the second embodiment of the utility model, the embodiment is based on the previous embodiment.
[0038] Specifically, the first rotating plate 104 is provided with a moving groove 104-2, and a locking block 2012 is arranged in the moving groove 104-2. The locking block 2012 is arranged to lock the position of a fixing column 2011 in a sliding groove 104-3.
[0039] The locking block 2012 is fixed with a spring 2013 on one side, and the other end of the spring 2013 is fixed to the inner wall of the moving groove 104-2. The spring 2013 exerts a pushing force on the locking block 2012, so that one end of the locking block 2012 is located in the sliding groove 104-3 under the condition of no other external force, thereby cooperating with the inner wall of the sliding groove 104-3 to lock the fixing column 2011 between the fixing column 2011 and the end inner wall of the sliding groove 104-3, and further lock the relative position of the first rotating plate 104 and the second rotating plate 105.
[0040] Specifically, one end of the locking block 2012 is inclined, and the locking block 2012 can be in contact with the fixing column 2011. When the fixing column 2011 is located at the middle position of the sliding groove 104-3, the end face of the fixing column 2011 will first contact and extrude the inclined surface of the locking block 2012 when the fixing column 2011 moves to any end of the sliding groove 104-3, so that the spring 2013 is compressed, and the locking block 2012 will completely enter the moving groove 104-2 without hindering the movement of the fixing column 2011. When the fixing column 2011 contacts the end inner wall of the sliding groove 104-3, the fixing column 2011 will not extrude the locking block 2012, and the spring 2013 will recover, so that one end of the locking block 2012 is located in the sliding groove 104-3 again. The right angle surface of the locking block 2012 will be in contact with the fixing column 2011, thereby hindering the reverse movement of the fixing column 2011. Through the cooperation of the locking block 2012 and the sliding groove 104-3, the fixing column 2011 is locked between the locking block 2012 and the inner wall of the sliding groove 104-3, thereby locking the position of the first rotating plate 104 and the second rotating plate 105.
[0041] Specifically, the number of locking blocks 2012 is two, which are close to the two ends of the sliding groove 104-1. When the fixing column 2011 is locked between the upper locking block 2012 and the inner wall of the sliding groove 104-3, the first rotating plate 104 and the second rotating plate 105 are in a parallel state, and the fixing long plate 102 and the second rotating plate 105 jointly constitute a sharp end for dispersing and preliminarily smoothing the mortar.
[0042] When the fixing column 2011 is locked between the lower locking block 2012 and the inner wall of the sliding groove 104-3, the first rotating plate 104 is perpendicular to the second rotating plate 105, the fixed long plate 102 is perpendicular to the second rotating plate 105, the first rotating plate 104 is collinear with the fixed short plate 103, at this time, the floor scraping ruler bottom surface is flat, the second rotating plate 105 is in contact with the floor, thereby the scraping construction is carried out.
[0043] Specifically, the locking block 2012 is fixed with a pull rope 2014 on one side, and the pull rope 2014 is used to release the position limitation of the fixing column 2011.
[0044] Specifically, the pull rope 2014 is fixed with a pull ring 2015 on one side, and the number of the pull rope 2014 corresponds to the number of the pull ring 2015.

[0049] Specifically, the fixed long plate 102 is provided with a first rotating groove 102-1, and the first rotating groove 102-1 is fixed with a first rotating shaft 1021 on the inner wall.
[0050] Specifically, the fixed short plate 103 is provided with a second rotating groove 103-1, and the second rotating groove 103-1 is fixed with a second rotating shaft 1031 on the inner wall.
[0051] The second rotating groove 103-1 is flush with the end face of the fixed short plate 103 at one end and is not flush with the end face of the fixed short plate 103 at the other end, and when the first rotating plate 104 is in contact with the end face of the second rotating groove 103-1 inside the fixed short plate 103, the first rotating plate 104 is in a vertical state and is collinear with the fixed short plate 103, thereby limiting the rotating direction of the first rotating plate 104, which can only rotate within the limit of the second rotating groove 103-1.
[0052] In use, after the mortar is placed in the designated position, the mortar needs to be dispersed, at which time the first rotating plate 104 is in a parallel state with the second rotating plate 105, the fixed column 2011 is locked between the upper locking block 2012 and the inner wall of the sliding groove 104-3, so that the bottom of the floor screed ruler has an inclined slope, and the fixed long plate 102 and the second rotating plate 105 together form a sharp tip, and the construction personnel can perform the dispersion of the mortar and the preliminary troweling work.
[0053] After the floor is scraped flat, the corresponding pull ring 2015 of the upper locking block 2012 is pulled, the pull rope 2014 is moved, the spring 2013 is compressed, the upper locking block 2012 will completely enter the moving groove 104-2, and will not hinder the movement of the fixed column 2011, and push the second rotating plate 105, so that the fixed column 2011 moves downward along the direction of the sliding groove 104-3, the end face of the fixed column 2011 will first contact and press the inclined surface of the lower locking block 2012, so that the spring 2013 is compressed, the locking block 2012 will completely enter the moving groove 104-2, and will not hinder the movement of the fixed column 2011, when the fixed column 2011 is in contact with the end face inner wall of the sliding groove 104-3, the fixed column 2011 will not press the locking block 2012, the spring 2013 will recover, and one end of the locking block 2012 will be located in the sliding groove 104-3 again, the right angle surface of the locking block 2012 will be in contact with the fixed column 2011, thereby preventing the fixed column 2011 from moving in the opposite direction, and through the cooperation of the locking block 2012 and the sliding groove 104-3, the fixed column 2011 is locked between the lower locking block 2012 and the inner wall of the sliding groove 104-3, thereby locking the positions of the first rotating plate 104 and the second rotating plate 105, at which time the first rotating plate 104 and the second rotating plate 105 are perpendicular to each other, and the fixed long plate 102 and the second rotating plate 105 are perpendicular, and the first rotating plate 104 is collinear with the fixed short plate 103, at which time the bottom surface of the floor screed ruler is flat, and the scraping work can be completed.
