[0023] Specific embodiments of the present invention will be described below with reference to the accompanying drawings. like Figure 1 to Figure 8 Shown: a door and window sealing rubber strip changer, consisting of a first bending plate 1, a second bending plate 2, a third bending plate 3 and a fourth bending plate 4,
[0024] The above-mentioned first bending plate 1 is composed of two sub-boards 5 that are perpendicular to each other, and two elongated holes 6 are symmetrically opened on one of the sub-boards 5,
[0025] The second bending plate 2 is also composed of two sub-boards 5 that are perpendicular to each other. Two long holes 6 are symmetrically opened on one sub-board 5, and three connecting bolts 7 are provided on the other sub-board 5. , and the three connecting bolts 7 are evenly distributed,
[0026] The third bending plate 3 is also composed of two sub-boards 5 that are perpendicular to each other, and one of the sub-boards 5 is provided with three long holes 6, and the positions of the three long holes 6 are the same as those of the above-mentioned three connecting bolts 7. one-to-one correspondence,
[0027] The fourth bending plate 4 includes a pressing plate 8, a connecting plate 9 perpendicular to it is connected to one side of the pressing plate 8, and a supporting plate 10 parallel to the pressing plate 8 is connected to one side of the connecting plate 9. , an operation long hole 11 is opened on the connecting plate 9, the middle of the operation long hole 11 is rotatably supported with a cutting shovel 12, and two rollers 13 are symmetrically arranged in the pressing plate 8, and the outer diameter of the roller 13 greater than the thickness of the pressing plate 8 .
[0028] Two support blocks 15 are symmetrically arranged in the middle of the operation long hole 11, and each support block 15 is provided with a longitudinally distributed long hole 6. The cutting shovel 12 is rotatably connected to the support block 15 through the long hole 6. This structure can make the cutting shovel 12 supported in the operation long hole 11 easily reverse the direction, so that the device can remove or install both the inner and outer rubber strips of the door and window frame.
[0029] Springs 16 are also arranged in the three long holes 6 on the third bending plate 3 .
[0030] The working process of the door and window sealing rubber strip changer according to the embodiment of the present invention is as follows: when the sealing rubber strip embedded in the groove of the door and window frame needs to be removed by using the device, only the fourth bending plate 4 is used to seal it with the opening facing the sealing strip. The attitude of the adhesive strip is buckled on the door and window frame (such as Figure 7 shown), at this time, the connecting plate 9 will remain parallel to the plane where the groove is located, and then insert the end of the cutting shovel 12, which is rotatably supported in the operating slot 11, into the groove along the length of the groove. Push the fourth bending plate 4, during this process, the cutting shovel 12 will cut the root of the sealing strip in the groove, Figure 7 The shaded part is cut off under the shear force of the cutting shovel 12 and the two side walls of the groove, and the remaining part of the sealant strip can be easily taken out of the groove as a whole due to its relatively small cross-sectional area, so that the sealant can be completely removed. thorough cleaning of the article;
[0031] When it is necessary to use this device to install a new sealing strip in the groove of the door and window frame, first connect the first bending plate 1 and the second bending plate 2 to the fourth bending plate 4, specifically, connect the first bending plate 1 and the second bending plate 2 to the fourth bending plate 4. The sub-plate 5 with the long hole 6 on the bending plate 1 is connected to the two threaded holes 14 of the pressing plate 8 on the fourth bending plate 4, and the sub-plate with the long hole 6 on the second bending plate 2 is connected. The plate 5 is also connected to the two threaded holes 14 of the pressing plate 8 on the fourth bending plate 4, and the area formed between the first bending plate 1 and the second bending plate 2 is used to accommodate the sealing strip; Then, connect the third bending plate 3 to the sub-plate 5 with the connecting bolts 7 on the second bending plate 2, and let a sub-plate 5 on the third bending plate 3 be fastened to the bottom of the door and window frame to form like Figure 8 state shown;
[0032] In this state, the spring 16 located in the long hole 6 on the third bending plate 3 can push up the three bolts 7 on the second bending plate 2, so that the third bending plate 3 can be connected to the door and window frame body. apply a certain amount of pressure;
[0033] Since all parts of the device are connected by long holes 6 and bolts, the relative positions between the parts can be adjusted according to the specific specifications of the door and window frame to ensure the working effect;
[0034] Then push the device along the length direction of the door and window frame. During the above movement process, the roller 13 on the pressing plate 8 will press the sealing strip, forcing the sealing strip into the groove to realize the installation of the sealing strip. .
