[0030] An amplitude adjustment component 4 is arranged inside the damping sleeve 3. The amplitude adjustment component 4 is composed of a threaded adjustment tube 401, a position support plate 402, and an internal damping spring 403. The threaded adjustment tube 401 is sleeved on the adjustment threaded rod 202 and is slidably connected to the adjustment threaded rod 202. The lower end of the threaded adjustment tube 401 is rotatably connected to the bottom of the damping sleeve 3. A threaded hole is opened at the center of the position support plate 402. The threaded adjustment tube 401 passes through the position support plate 402 and is threadedly connected to the position support plate 402 through the threaded hole. An internal damping spring 403 is sleeved outside the threaded adjustment tube 401, and the lower end of the internal damping spring 403 is fixedly connected to the position support plate 402. A hexagonal adjustment groove 404 is opened at the upper end port of the threaded adjustment tube 401.

[0031] An extension support tube 6 is slidably connected in the relief hole of the damping sleeve 3. The lower end of the extension support tube 6 is sleeved on the threaded adjustment tube 401.

[0032] Angle adjustment mounting seats 7 are respectively installed at the top end of the extension support tube 6 and the bottom of the base mounting box 1. Among them, the angle adjustment mounting seat 7 installed at the top end of the extension support tube 6 is the top mounting seat, and the angle adjustment mounting seat 7 installed at the bottom of the base mounting box is the base mounting seat.

[0033] Each angle adjustment mounting seat 7 includes an adjustment fixing frame 701. The bottom of the adjustment fixing frame of the top mounting seat is fixedly connected to the top end of the extension support tube. The top of the adjustment fixing frame of the base mounting seat is fixedly connected to the bottom of the base mounting box. One side of the adjustment fixing frame 701 is hinged with a positioning connecting plate 702. Two positioning threaded rods 705 are arranged in parallel inside the adjustment fixing frame 701. One end of each positioning threaded rod 705 is rotatably connected to the inner wall of one side of the adjustment fixing frame 701 where the positioning connecting plate 702 is hinged. Sprockets 706 are respectively installed outside the ends of the positioning threaded rods 705 on this side. The two sprockets 706 are connected by a synchronous chain 707. The other ends of the two positioning threaded rods 705 are respectively rotatably connected to the side wall of the adjustment fixing frame 701 on the corresponding side, and the positioning threaded rod 705 penetrates through the side wall of the adjustment fixing frame 701 on this side and is connected to a handle 710 outside the adjustment fixing frame 701. By rotating the handle 710, the positioning threaded rod 705 connected to the handle 710 can be rotated, and this positioning threaded rod 705 drives the other positioning threaded rod 705 to rotate through the transmission of the synchronous chain 707.

[0034] A support and adjustment plate 703 is provided on the positioning screw rod 705. Threaded holes are respectively provided in the support and adjustment plate 703 at positions corresponding to the two positioning screw rods 705. The support and adjustment plate 703 is threadedly connected to the positioning screw rod 705 through the threaded holes. A spring-damper telescopic rod 704 is provided at each end of the support and adjustment plate 703. The lower end of the spring-damper telescopic rod 704 is hinged to the support and adjustment plate 703, and the other end of the spring-damper telescopic rod 704 is hinged to the positioning connection plate 702. By adjusting the position of the support and adjustment plate 703 with the positioning screw rod 705, the spring-damper telescopic rod 704 is driven to fold and extend, so as to achieve the function of adjusting the inclination angle of the positioning connection plate 702.

[0035] In this embodiment, fixing installation holes one 708 are respectively provided at the four top corners of the adjustment fixing frame 701. Fixing installation holes two 709 are also provided at positions corresponding to the fixing installation holes one 708 at the four top corners of the positioning connection plate 702. The fixing installation holes one 708 and the fixing installation holes two 709 are used for the connection between this device and the external environment.

[0036] Amplitude adjustment holes 8 are also respectively provided at the centers of the positioning connection plate 702 and the adjustment fixing frame 701. The amplitude adjustment holes 8 are communicated with the hexagonal adjustment groove 404 at the top end of the threaded adjustment pipe 401 through the extension support pipe 6.

[0037] This device is used between two building structures. When an external force acts on the damper body, damping buffering is carried out between the extension support pipe 6 and the damping sleeve 3 and between the extension support pipe 6 and the threaded adjustment pipe 401.

[0038] When the height of this device needs to be adjusted, rotate the knob 204. The knob 204 drives the adjustment bevel gear 203 to rotate. The adjustment bevel gear 203 drives the adjustment screw rod 202 to rotate by meshing with the linkage bevel gear 201. The adjustment screw rod 202 moves up and down along the inner wall of the foundation installation box 1 through the threaded connection with the damping sleeve 3, so that the damper body reaches the required height; when the amplitude of the damper body needs to be adjusted, use a hexagonal wrench to insert into the hexagonal adjustment groove 404 from the amplitude adjustment hole 8 and the extension support pipe 6, and rotate the threaded adjustment pipe 401. While the threaded adjustment pipe 401 rotates, the position support plate 402 moves up and down along the threaded adjustment pipe 401. When the position support plate 402 rises, the position support plate 402 compresses the internal damping spring 403. When the position support plate 402 descends, the position support plate 402 releases the internal damping spring 403, so as to achieve the function of adjusting the amplitude of the damper body.

[0039] When the positioning connecting plate 702 of the device fits with the adjusting and fixing frame 701, the supporting and adjusting plate 703 is placed on the side close to the sprocket 706, and the hinged end of the supporting and adjusting plate 703 and the positioning connecting plate 702 is placed at one end close to the handle 710; when the device is used to connect two building structures with a certain included angle, it is necessary to adjust the included angle between the positioning connecting plate 702 and the adjusting and fixing frame 701 in the angle adjusting mounting seat 7. During adjustment, rotate one of the handles 710, and the handle 710 drives the positioning threaded rod 705 connected to it to rotate. The positioning threaded rod 705 drives the other positioning threaded rod 705 to rotate through the synchronous chain 707. The rotation of the two positioning threaded rods 705 drives the supporting and adjusting plate 703 to move, and the supporting and adjusting plate 703 drives the spring damping telescopic rod 704 to fold and extend, adjusting the included angle between the positioning connecting plate 702 and the adjusting and fixing frame 701. At the same time, when the positioning connecting plate 702 is subjected to an external force, it can also perform damping buffering through the spring damping telescopic rod 704.

[0040] The present invention realizes the height adjustment of the damper body through the threaded connection between the telescopic sleeve and the adjusting threaded rod, increasing the use length of the damper body; angle adjusting mounting seats are respectively installed at the upper and lower ends of the damper body to meet the connection between two building structures with an included angle, improving the adaptation range of the installation angle of the damper body, and further greatly increasing the adaptability of the device to the environment. The device adjusts the position of the position support plate through the threaded adjustment tube, and then adjusts the compression of the internal damping spring, adjusting the amplitude of the damper body, and further improving the working effect of the damper body.

[0041] Finally, it should be noted that the above-listed are only the preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and its equivalent technologies, they should be considered within the protection scope of the present invention.
