[0026] In this embodiment, a load-bearing rod with one end penetrating through and extending to the lower side of the lower cross plate No. 1 is fixed to both left and right ends of the lower surface of the upper cross plate No. 1. The load-bearing rod is fixed to the lower cross plate No. 1 by bolts, and the two load-bearing rods are symmetrically distributed on the left and right sides of the vertical central axis of the two cross plates No. 1.

[0027] Among them, a U-shaped plate is fixed on the top of the vertical pole channel steel 3, and spring buffer rods are fixed on the left and right ends of the inner bottom wall of the U-shaped plate. The upper surface of the spring buffer rods at the left and right ends is fixed with the same buffer block, which fixes the buffer block to the inner top surface of the hospital building.

[0028] It should be noted that a hinge seat 4 is fixed to the top of the four sides of the vertical pole channel steel 3, one side of the hinge seat 4 is hingedly connected to a hinge plate 5, the other end of the hinge plate 5 is hingedly connected to the hinge seat 4, and then one end of the hinge seat 4 is fixed to the inner top surface of the hospital building, and the adjustable seismic support and hanger can be assembled and installed.

[0029] See also Figure 2 In order to facilitate the assembly of annular sleeves 602 of different sizes, the fixing mechanism 6 in this embodiment includes a mounting plate 601 fixed on the opposite side of the two No. 1 horizontal plates 1, an annular sleeve 602 is fixed between the opposite sides of the two mounting plates 601, a guide rod 603 is fixed between the opposite sides of the left and right side walls of the inner cavity of the No. 1 horizontal plate 1 at the lower end, and a movable plate 604 is slidably connected to the left and right ends of the outer surface of the guide rod 603, a connecting plate 605 is fixed between the opposite sides of the inner top wall and the inner bottom wall of the No. 1 horizontal plate 1 at the lower end, and a reset spring 606 is fixed between the movable plate 604 and the opposite side of the connecting plate 605, and the reset spring 606 is sleeved on the outer surface of the guide rod 603, and the movable plate 604 is slidably connected to the left and right ends of the outer surface of the guide rod 603. Move one side close to the connecting plate 605, and the reset spring 606 will be squeezed when the movable plate 604 moves. The reset spring 606 is shortened as the movable plate 604 moves. Linkage plates 607 are provided on the left and right ends of the upper side of the lower end No. 1 horizontal plate 1, and the tops of the two linkage plates 607 on the opposite sides are fixed with a fixing rod 608 with one end penetrating and extending into the inner cavity of the annular sleeve 602. A clamping plate 609 is fixed between the opposite sides of the two fixing rods 608, which drives the linkage plates 607, the fixing rod 608 and the clamping plate 609 at the left and right ends to move back to back, thereby increasing the gap between the two clamping plates 609, and then the ventilation duct to be installed is inserted from one side of the annular sleeve 602.

[0030] In this embodiment, pads are fixed on the side opposite to the inner top wall and the inner bottom wall of the annular sleeve 602, and the pads are rubber blocks. Guide strips are fixed on the left and right ends of the inner bottom wall of the lower horizontal plate No. 1. The bottom of the movable plate 604 makes horizontal linear motion in the inner cavity of the guide strip. The guide strip is a rectangular parallelepiped with an open upper surface.

[0031] It can be understood that after adjusting to the appropriate position, the limit of the two shift plates can be released. At this time, the return spring 606 rebounds without being squeezed and pushes the movable plate 604 to slide on the outer surface of the guide rod 603, so that the two movable plates 604 synchronously drive the linkage plates 607, the fixed rod 608 and the clamping plate 609 at the left and right ends to make relative movements, thereby fixing and assembling the ventilation duct located in the inner cavity of the annular sleeve 602.

[0032] Among them, through holes are opened on both ends of the inner top wall of the lower end horizontal plate No. 1, the top of the movable plate 604 passes through the through hole and extends to the upper side of the through hole and is fixed to the linkage plate 607, and anti-slip pads are fixed on the opposite sides of the two clamping plates 609. The anti-slip pads are rubber pads, and the anti-slip pads increase the friction between the clamping plate 609 and the ventilation duct.

[0033] In addition, a shift plate is fixed on the front of the movable plate 604, a guide hole is opened on the front of the lower end first horizontal plate 1, and the front of the shift plate passes through the guide hole and extends to the front side of the guide hole.

[0034] It should be noted that two clamping plates 609 are arranged in the inner cavity of the annular sleeve 602. The two clamping plates 609 can move relative to each other through the setting of the fixing mechanism 6, so that they can be used to fix and assemble ventilation ducts of different sizes, which greatly improves the flexibility and applicability during use, and the stability of the fixed ventilation ducts is better.

[0035] See also Figures 3 to 4 In order to adjust the angle of the hinged plate 5, the adjusting mechanism 7 in this embodiment includes an accommodating chamber 701 provided at the bottom of the left and right ends of the inner cavity of the upper first horizontal plate 1 and the top of the front and rear sides of the second horizontal plate 2. A bidirectional screw 702 is rotatably connected between the left and right side walls of the inner cavity of the accommodating chamber 701 and the opposite side of the front and rear side walls of the inner cavity through a bearing. A driven bevel gear 703 is fixed to the outer surface of the bidirectional screw 702. The upper surface of the driven bevel gear 703 is meshedly connected with a driving bevel gear 704. The rotation of the driving bevel gear 704 causes the driven bevel gear 703 meshed with it to rotate, and the rotation of the driven bevel gear 703 can drive the bidirectional screw The rod 702 rotates, and the left and right ends of the outer surface of the bottom bidirectional screw 702 and the front and rear sides of the top bidirectional screw 702 are threadedly connected with movable sleeves 705. A vertical plate 706 is fixed to the upper surface of the movable sleeve 705. The top of the vertical plate 706 penetrates and extends to the upper side of the upper horizontal plate 1 and is fixed with a movable plate 707. The rotation of the bidirectional screw 702 can make the two movable sleeves 705 threadedly connected to the surface of the bidirectional screw 702 move relative to or away from each other. The movement of the movable sleeve 705 makes the two vertical plates 706 drive the movable plate 707 to move, so that the bottom hinge seat 4 can be moved, and the angle of the hinge plate 5 can be adjusted.

[0036] In this embodiment, a driving rod with one end passing through and extending to the upper side of the active bevel gear 704 is fixed to the upper surface, and the two top and two bottom movable sleeves 705 are symmetrically distributed on the front and rear sides of the vertical center axis of the top bidirectional screw 702 and the left and right sides of the vertical center axis of the bottom bidirectional screw 702.

[0037] In addition, the bidirectional screw rods 702 in the second horizontal plate 2 on the front and rear sides are the same bidirectional screw rod 702.

[0038] Among them, the upper surface of the movable plate 707 is fixed to the bottom hinge seat 4, and limiting grooves are provided at the left and right ends or the front and rear sides of the inner bottom wall of the accommodating cavity 701. A limiting block is fixed on the lower surface of the movable sleeve 705, and the limiting block makes horizontal linear motion in the inner cavity of the limiting groove. When the movable sleeve 705 moves, it will drive the limiting block to move, and the limiting block will move in the inner cavity of the limiting groove, thereby limiting the movement of the movable sleeve 705, so that the movable sleeve 705 can only move in a linear direction.

[0039] It should be noted that by adjusting the angle of the hinged plate 5, the space can be better planned and utilized within a limited space, thereby avoiding conflicts with other building structures, improving space utilization, and helping to adjust and optimize the structural stability of the seismic support and hanger.

[0040] The working principle of the above embodiment is:

[0041] (1) When assembling the ventilation duct, the two plates are pushed toward one side of the load-bearing rod. The movement of the two plates can synchronously drive the movable plate 604 to move toward the side close to the connecting plate 605. When the movable plate 604 moves, the return spring 606 is squeezed. The return spring 606 shortens with the movement of the movable plate 604, and drives the linkage plates 607, the fixing rod 608 and the clamping plate 609 at the left and right ends to move in opposite directions, thereby increasing the gap between the two clamping plates 609. Then, the ventilation duct to be installed is inserted from one side of the annular sleeve 602. After adjusting to a suitable position, the limit of the two plates can be released. At this time, the return spring 606 rebounds without being squeezed and pushes the movable plate 604 to slide on the outer surface of the guide rod 603, so that the two movable plates 604 synchronously drive the linkage plates 607, the fixing rod 608 and the clamping plate 609 at the left and right ends to move relative to each other, thereby fixing and assembling the ventilation duct located in the inner cavity of the annular sleeve 602.

[0042] (2) When adjusting the angle of the hinge plate 5, the driving rod can be rotated. The rotation of the driving rod causes the active bevel gear 704 fixed on its surface to rotate. The rotation of the active bevel gear 704 causes the driven bevel gear 703 meshing with it to rotate. The rotation of the driven bevel gear 703 can drive the bidirectional screw 702 to rotate, so that the two movable sleeves 705 threadedly connected to the surface of the bidirectional screw 702 can move relative to or away from each other. At this time, the movable sleeve 705 will drive the limit block to move when moving. The limit block will move in the inner cavity of the limit groove, so that the movement of the movable sleeve 705 can be limited. Then, the movement of the movable sleeve 705 causes the two vertical plates 706 to drive the movable plate 707 to move, so that the bottom hinge seat 4 can be moved, and the angle of the hinge plate 5 can be adjusted.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
