[0039] Example 1
[0040] Such as Figure 1-Figure 5 As shown, the plastering device for the connecting part of the wall and the ceiling of the present invention includes a wiper board I1 and a wiper board II2. One side of the wiper board I1 is connected to one side of the wiper board II2, and the wiper board I1 and the wiper board II2 are connected. The boards II2 are perpendicular to each other. On the opposite surfaces of the wipe board I1 and the wipe board II2, there are provided a support board 3 and a handle 4 connected in sequence. One side of the support board 3 is connected with the wipe board I1 and the wipe board II2. The parts are connected, and the support plate 3 is parallel to the connecting edge between the wiper board I1 and the wiper board Ⅱ2, and the right angle formed between the wiper board I1 and the wiper board II2 is equally divided;
[0041] One end of the handle 4 is connected to one end of the support plate 3, and the other end of the handle 4 extends in a direction away from the support plate 3;
[0042] A number of telescopic rods 5 are arranged between the wiper board I1 and the support board 3, the axes of the telescopic rods 5 are all perpendicular to the wiper board I1, one end is connected to the wiper board I1, and the other end is connected to the support board 3. , And the telescopic rod 5 is arranged between the wiper board I1 and the support board 3 at even intervals along the connecting edge line between the wiper board I1 and the wiper board II2.
[0043] When painting the connecting part between the wall and the ceiling, hold the handle 4 so that the wiping board I1 is in contact with the wall, and the wiping board Ⅱ2 is in contact with the ceiling, so that the wall and ceiling are painted. This way, the wall and the ceiling can be painted at the same time with one wave, which not only avoids damaging the painted surface on the other side when applying one side alone, causing repeated repairs in the later period and increasing the time cost, but also improves the work efficiency.
[0044] At the same time, when the wiper board I1 and the wiper board II2 are not perpendicular to each other due to collisions, etc., adjust the length of the telescopic rod 5 so that the wiper board I1 and the wiper board II2 are perpendicular to each other, so that the present invention and the wall and the ceiling The angles are consistent, which facilitates the simultaneous application of the wall and the ceiling using the invention. For example, when the angle between the wiper board I1 and the wiper board II2 is an acute angle, the length of the telescopic rod 5 is increased so that the wiper board I1 moves away from the support board 3, and then the wiper board I1 and the wiper board Ⅱ The plate II2 is perpendicular to each other; when the angle between the wiper board I1 and the wiper board Ⅱ2 is an obtuse angle, the length of the telescopic rod 5 is shortened so that the wiper board I1 is pulled toward the support board 3, and then the wiper board I1 and Wiping boards II 2 are perpendicular to each other.
[0045] Further, the telescopic rod 5 includes a threaded barrel 6, a screw 7 and a fixing block 8 which are connected in sequence and coaxially. The bottom of the threaded barrel 6 is connected to the wiper plate I1, and one end of the screw 7 is inserted into the threaded barrel 6. The other end of the screw 7 is rotatably connected with the fixed block 8. The end of the fixed block 8 far away from the screw 7 is connected with the support plate 3, and the screw 7 can rotate around its own axis. And the fixed block 8 does not rotate.
[0046] When shortening or extending the telescopic rod 5, the screw 7 can be rotated.
[0047] Preferably, the wiper board I1 and the wiper board II2 are formed by bending a steel plate, the portion of the steel plate on the bent side is the wiper board I1, and the portion on the other side of the bend is the wiper board II2; When the smearing angle is obtuse or acute, adjust the length of the telescopic rod 5 to enlarge the angle between the wiper Ⅰ1 and the wiper Ⅱ2 or reduce the included angle between the wiper Ⅰ1 and the wiper Ⅱ2; compared to the direct welding connection For wiper Ⅰ1 and wiper Ⅱ2, the adjustable angle between wiper Ⅰ1 and wiper Ⅱ2 formed by bending a steel plate is larger and the service life is longer.
[0048] A rotating rod 17 is provided on the side wall of the screw 7 close to the fixed block 8. The axis of the rotating rod 17 is perpendicular to the axis of the screw 7.
[0049] There are three rotating rods 17 and they are symmetrically arranged on the side wall of the screw 7 along the axis of the screw 7.
[0050] The setting of the rotating rod 17 makes the rotating screw 7 more labor-saving.
[0051] Further, a limit plate 9 is slidably arranged between the wipe board II2 and the support plate 3, and the limit board 9 is parallel to the connecting edge line between the wipe board I1 and the wipe board II2;
[0052] A mounting block 10 is provided on the end of the wiper plate II2 close to the support plate 3, and an end of the mounting block 10 far away from the wiper plate II2 and the end of the support plate 3 near the wiper plate II2 are both provided with a mounting groove 11, the mounting groove The axes of 11 are parallel to the connecting edge line between the wiper board I1 and the wiper board II2, and the opening size of the mounting groove 11 is smaller than the groove bottom size;
[0053] Both ends of the limit plate 9 are provided with connecting blocks 12, the cross-sectional size of the connecting block 12 and the cross-sectional size of the mounting groove 11 are the same, the connecting blocks 12 are respectively fitted with a mounting groove 11, and can be installed along the The axis of the groove 11 moves.
[0054] The installation groove 11 is a dovetail groove.
[0055] The setting of the limit plate 9 not only fixes the angle between the support plate 3 and the wiper Ⅱ2, but also facilitates the support for the wiper Ⅱ2, which is beneficial to control the wiper Ⅱ2 when applying wall dust.
[0056] Further, the handle 4 includes a fixed rod 13 parallel to each other, a holding rod 14, and a connecting rod 15 arranged between the fixed rod 13 and the holding rod 14. One end of the fixed rod 13 is connected to the support plate 3 to fix The other end of the rod 13 is connected to one end of the holding rod 14 through the connecting rod 15, and the axis of the connecting rod 15 is perpendicular to the axis of the fixing rod 13.
[0057] Further, a U-shaped stop rod 16 is provided on the side wall of the holding rod 14. The ends of the stop rod 16 are connected to the side wall of the holding rod 14, and the stop rod 16 and the holding rod 14 are enclosed The axis of the hole is perpendicular to the axis of the holding rod 14.
[0058] Because the ceiling is located above the head of the construction worker, the unstable holding force will cause the trowel to fall to the ground during painting; therefore, the stop lever 16 is set to prevent the stop lever 16 from being held when the fingers are loosened. The trowel will fall off directly from the fingers, thus reducing the probability of the trowel falling off the hand when the holding is unstable.
