[0025] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0026] Example: As attached Figure 1 To Attachment Figure 5 As shown: the utility model provides an upper shaft structure for a sky and earth shaft door, comprising an upper shaft housing 1, a cover plate 2 and a sliding assembly; movable pieces 4 are installed on both inner walls of the upper shaft housing 1, and a first oblique groove 37, a second oblique groove 38, a transverse guide groove 39 and a circular hole 40 are opened on the surface of the movable piece 4;

[0027] The sliding assembly includes a first sliding positioning block 12 , a second sliding positioning block 13 , a third sliding positioning block 14 , a fixed plate 15 and a fourth sliding positioning block 16 which are installed between the two groups of movable plates 4 .

[0028] The two side walls of the upper shaft housing 1 are each provided with a first long groove 48 , a third long groove 51 and two groups of second long grooves 49 .

[0029] A third screw hole 28, a positioning hole 29 and a fourth screw hole 31 are provided on the upper surface of the cover plate 2. The first positioning column 17 is fixedly connected to the upper surfaces of the first sliding positioning block 12 and the third sliding positioning block 14. The first positioning column 17 is connected to the third screw hole 28. The round shaft 3 is fixedly connected to the upper surface of the second sliding positioning block 13. The round shaft 3 is located in the positioning hole 29.

[0030] A first pin hole 18 is penetrated through the side wall of the first sliding positioning block 12, two groups of second pin holes 19 are penetrated through the side wall of the second sliding positioning block 13, and the positions of the two groups of second pin holes 19 correspond to the first oblique groove 37 and the second oblique groove 38 respectively, a third pin hole 21 is penetrated through the side wall of the third sliding positioning block 14, and second positioning columns 26 are connected to both end surfaces of the fourth sliding positioning block 16, and the second positioning columns 26 are limitedly installed with the circular hole 40;

[0031] A third long pin 11 is installed between the first pin hole 18, the first oblique groove 37 and the third long groove 51;

[0032] The inner walls of the two groups of second pin holes 19 are both limitedly installed with second long pins 10; the two groups of second long pins 10 are respectively located in the first oblique groove 37 and the second oblique groove 38, and the two groups of second long pins 10 are both located in the second long groove 49;

[0033] A first long pin 8 is installed between the third pin hole 21 , the transverse guide groove 39 and the first long groove 48 .

[0034] The fixing plate 15 is limitedly installed in the upper shaft housing 1, and a first narrow surface screw hole 46 and a second narrow surface screw hole 47 are provided on one side of the narrow surface of the upper shaft housing 1; the third sliding positioning block 14 and the fourth sliding positioning block 16 are penetrated by the first screw hole 22 on the side wall, and a column head adjustment screw 5 is installed between the first screw hole 22 and the fixing plate 15; the positions of the two groups of column head adjustment screws 5 are respectively aligned with the first narrow surface screw hole 46 and the second narrow surface screw hole 47.

[0035] Before inserting the third sliding positioning block 14 , first insert the column head adjustment screw 5 into the fixing plate 15 and then screw it into the first screw hole 22 on the third sliding positioning block 14 ; first insert the column head adjustment screw 5 into the fixing plate 15 and then screw it into the first screw hole 22 on the fourth sliding positioning block 16 .

[0036] Use the third long pin 11 to pass through the third long slot 51, the first oblique slot 37 and the first pin hole 18. When the third long pin 11 passes through the first pin hole 18, it needs to be tapped and clamped;

[0037] Use the second long pin 10 to pass through the second long slot 49, the first oblique slot 37 and the second pin hole 19. When the second long pin 10 passes through the second pin hole 19, it needs to be tapped and clamped;

[0038] Another second long pin 10 passes through the second long slot 49, the second oblique slot 38 and the second pin hole 19. When the second long pin 10 passes through the second pin hole 19, it needs to be tapped and clamped;

[0039] Use the first long pin 8 to pass through the first long groove 48 , the transverse guide groove 39 and the third pin hole 21 . When the first long pin 8 passes through the third pin hole 21 , it needs to be tapped and clamped.

[0040] A wire groove 32 is provided on the upper surface of the cover plate 2, and the wire groove 32 is located around the positioning hole 29. The wire groove 32 is used for laying wires. The wires pass through the inside of the round shaft 3 and then through the bottom of the upper shaft shell 1 to penetrate into the door and window profile. The third screw hole 28 is aligned with the first positioning column 17 and fastened with screws, and then the cover plate 2 is installed on the screw hole position on the profile through the fourth screw hole 31.

[0041] As can be seen from the above, at the first narrow face screw hole 46, use a hexagon socket tool to adjust the column head adjustment screw 5 clockwise or counterclockwise to displace the center line of the upper shaft housing 1 and the cover plate 2 to the left and right, that is, the longitudinal center line of the upper shaft housing 1 is offset from the longitudinal center line of the cover plate 2. When the two center lines are longitudinally aligned, it is the initial installation position. With the adjustment of the column head adjustment screw 5, the left and right displacements occur by 5 mm each, and the total displacement distance is 10 mm.

[0042] At the second narrow face screw hole 47, use a hexagon socket tool to adjust the column head adjustment screw 5 clockwise or counterclockwise. Because the column head adjustment screw 5 is screwed on the screw hole on the fourth sliding positioning block 16, when tightening or loosening the fourth sliding positioning block 16 and the column head adjustment screw 5, the column head end approaches or moves away from the fourth sliding positioning block 16, and because the fixing plate 15 is fixed at the groove on the inner wall of the upper shaft housing 1, the column head of the column head adjustment screw 5 is clamped between the fixing plate 15 and the inner wall of the upper shaft housing 1, causing the fourth sliding positioning block 16 to be displaced in the upper shaft housing 1. This is because the fourth sliding positioning block 16 has second positioning columns 26 on both sides, and the second positioning columns 26 are stuck in the movable plates 4 on both sides of the inner wall of the upper shaft housing 1 The fourth sliding positioning block 16 is displaced in the circular hole 40 on the upper shaft housing 1, and the displacement of the fourth sliding positioning block 16 can drive the two movable plates 4 to be displaced, and the displacement distance is equal (displacement distance 15.3 mm). In addition, because the second sliding positioning block 13 is passed through the second long slot 49 vertically overlapped on the upper shaft housing 1 by the two second long pins 10, and also passes through the first oblique slot 37 and the second oblique slot 38 on the two groups of movable plates 4 on both sides of the upper shaft housing 1, when the column head adjustment screw 5 is adjusted, the fourth sliding positioning block 16 is displaced, and the second positioning columns 26 on both sides cooperate with the circular holes 40 of the two movable plates 4 to drive the movable plates 4 to be displaced. At this time, the second sliding positioning block 13 is restricted from left and right lateral displacement by the second long slot 49 vertically of the upper shaft housing 1;

[0043] As the two movable plates 4 move laterally, the intersection of the first oblique groove 37 and the second long groove 49 moves up and down, that is, the intersection of the second oblique groove 38 and the second long groove 49 moves up and down, and the second long pin 10 passes through the intersection of the first oblique groove 37 and the second long groove 49, and another second long pin 10 passes through the intersection of the second oblique groove 38 and the second long groove 49, and then the two groups of second long pins 10 push the second sliding positioning block 13 to move up and down due to the up and down displacement of the intersection;

[0044] The second sliding positioning block 13 is provided with a round shaft 3, and the longitudinal height adjustment of the round shaft 3 on the surface of the cover plate 2 is controlled by adjusting the column head adjustment screw 5. The height of the round shaft 3 protruding from the surface of the cover plate 2 is controlled by the up and down displacement distance.

[0045] Rotate the column head adjustment screw 5 clockwise or counterclockwise, and the threaded teeth on the column head adjustment screw 5 engage with the inner tapping of the first screw hole 22. Because the fixing plate 15 is fixed in the groove, when the third sliding positioning block 14 and the column head adjustment screw 5 are tightened or loosened, the column head end approaches or moves away from the third sliding positioning block 14, and the column head of the column head adjustment screw 5 is clamped between the fixing plate 15 and the inner wall of the upper shaft housing 1. The relationship between tightening or loosening the column head adjustment screw 5 causes the upper shaft housing 1 to be laterally offset relative to the cover plate 2. The upper shaft housing 1 is connected to the circular shaft 3, and the circular shaft 3 is laterally displaced in the positioning hole 29 relative to the cover plate 2. The adjustment of the column head adjustment screw 5 causes a left and right displacement of 5 mm each, and a total displacement distance of 10 mm.

[0046] Rotate the column head adjustment screw 5 clockwise or counterclockwise, and the threaded teeth on the column head screw rod engage with the internal tapping of the first screw hole 22. When the third sliding positioning block 14 and the column head adjustment screw 5 are tightened or loosened, the column head end approaches or moves away from the fourth sliding positioning block 16, so that the second positioning column 26 moves horizontally between the two movable plates 4, so that the two groups of movable plates 4 are displaced in the same direction at the same time, so that the intersection angle of the longitudinal long circular hole on the upper shaft housing 1 and the oblique groove on the movable plate 4 is displaced up and down, and there is a long pin in the intersection angle, and the long pin drives the round shaft 3 at the telescopic top to move up and down with the displacement height of the intersection angle.

[0047] This enables fine-tuning of the door installation position, including precise lateral and longitudinal offsets. This adjustment mechanism allows the user to fine-tune the center position and height of the door according to the actual installation environment to ensure perfect alignment of the door and door frame.
