DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Combine the following Figures 1 to 8 A lasso-type damper of the present invention is described.

[0034] like Figures 1 to 3 As shown, in one embodiment, a lasso 500 type damper includes a damper body 100, a linear movable rod 200, an active kit 400, a first active plate 610 and a second active plate 620; an active chamber 110 is provided inside the damper body 100, and fluid chambers 120 are provided at the upper and lower ends of the active chamber 110, and the fluid chamber 120 is filled with a fluid damping medium; the linear movable rod 200 longitudinally penetrates the damper body 100 and is arranged at the center of the active chamber 110; the active kit 400 is covered on the outside of the damper body 100, and the active kit 400 can move in the longitudinal direction, and the top of the active kit 400 The inner side is connected to the linear movable rod 200, and the outer side of the top end of the movable kit 400 is gathered by the lasso 500 and fixed at the target position; the first movable plate 610 is located in the movable chamber 110 and is movably installed on the linear movable rod 200, and the linear movable rod 200 is used to drive the first movable plate 610 to move longitudinally; the second movable plate 620 is located in the movable chamber 110 and is movably installed on the linear movable rod 200, and the linear movable rod 200 is used to drive the second movable plate 620 to move longitudinally and rotate; when the second movable plate 620 rotates, the connecting channel between the two fluid chambers 120 increases or decreases.

[0035] Specifically, when in use, the damper body 100 is placed in a suitable position according to the requirements of the construction site, and then the movable kit 400 and itself are located in a suitable position by moving the linear movable rod 200. At this time, the end of the linear movable rod 200 is connected to a connection target, and the end of the movable kit 400 is connected to another target, so that the movable kit 400 is sleeved on the target surface, and according to the limit structure set by the target, the lasso 500 is used to tighten the end of the movable kit 400, so that the movable kit 400 can be tightly connected to the target. At the same time, according to the damping force of the damping device required by the target, the linear movable rod 200 can be rotated to change the angle between the first movable plate 610 and the second movable plate 620, so as to adjust the size of the connecting channel between the two fluid chambers 120, thereby changing the flow rate of the fluid damping medium.

[0036] The lasso-type damper mentioned above, when in use, places the damper body 100 at a suitable position according to the requirements of the construction site, and then moves the linear movable rod 200 to place the movable kit 400 and itself at a suitable position. At this time, the end of the linear movable rod 200 is connected to a connection target, and the end of the movable kit 400 is connected to another target, so that the movable kit 400 is sleeved on the target surface, and the lasso 500 is used to converge the end of the movable kit 400 according to the limit structure set by the target, so that the movable kit 400 can be tightly connected to the target. The connection method is diverse and can be applicable to various areas and structures in the construction site. At the same time, according to the damping force of the damping device required by the target, the linear movable rod 200 can be rotated to change the angle between the first movable plate 610 and the second movable plate 620, so as to adjust the size of the connecting channel between the two fluid chambers 120, thereby changing the flow velocity of the fluid damping medium, and there is no need to replace the damper due to specification restrictions within a certain range.

[0037] like Figure 5 As shown, in one embodiment, the linear moving rod 200 includes a piston rod 210, a connecting seat 220 and a positioning plate 230; one end of the piston rod 210 longitudinally penetrates the damper body 100, two positioning plates 230 are arranged at intervals at the upper end of the piston rod 210, and the connecting seat 220 is installed at the lower end of the piston rod 210.

[0038] Specifically, Figure 4 As shown, the damper is arranged in a columnar structure, and the innermost center thereof is an active chamber 110, which is used to install the first active plate 610 and the second active plate 620. The two ends of the active chamber 110 are arranged from near to far as the fluid chamber 120 and the end chamber 130, wherein the fluid chamber 120 is separated from the end chamber 130, and the central axis of the piston rod 210 coincides with the central axis of the active chamber 110, the fluid chamber 120 and the end chamber 130. The two end chambers 130 are connected by a connecting pipe, and a driving device for liquid driving is arranged on the connecting pipe, which is used to remove the residual liquid or gas in the end chamber 130.

[0040] Specifically, the curvature of the first curved plate 410 is the same as that of the second curved plate 420, that is, the second curved plate 420 and the first curved plate 410 can be regarded as one body, and the only difference is that the second curved plate 420 has a smaller area and there is a gap between two adjacent second curved plates 420. This structural setting enables the second curved plate 420 to be bent by the lasso 500 when being contracted by the lasso 500, while the first curved plate 410 will not be deformed to affect its longitudinal movement.

[0041] In one embodiment, an adapter 300 is installed between the two positioning plates 230, and the adapter 300 includes a sleeve 310, a hinge seat 320, a connecting rod 330 and a fastener 340; the sleeve 310 is movably sleeved on the piston rod 210, and the sleeve 310 is located between the two positioning plates 230, and a plurality of hinge seats 320 are arranged in a circular array on the sleeve 310, and each hinge seat 320 is connected to two connecting rods 330, and the connecting rod 330 can swing in the horizontal direction, and one end of the connecting rod 330 is inserted into the plug hole 411 opened on the first arc plate 410, and the fastener 340 is installed at this end of the connecting rod 330.

In order to reduce the selection cost of the device, except for the damper body 100 and the movable kit 400, other components are of uniform specifications. Therefore, in order to enable the adapter 300 to always maintain the connection with the damper body 100 and the movable kit 400, the two connecting rods 330 installed on the same hinge seat 320 can swing, so as to adapt to various specifications of damper bodies 100 and movable kits 400.

[0044] Specifically, the folding plate 440 is composed of three parts, the middle part is an arc-shaped plate structure, and the two ends are fan-shaped plate structures.

[0045] In one embodiment, the upper and lower bent ends of the folding plate 440 are both provided with through holes 441, and a positioning rod 150 is longitudinally inserted into the through hole 441. The two ends of the positioning rod 150 are respectively connected to the upper and lower ends of the annular area 140, and a spring 460 is arranged between the bent end of the folding plate 440 and the upper and lower ends of the annular area 140, and the spring 460 is sleeved on the positioning rod 150.

[0046] Specifically, two adjacent folding plates 440 are connected by an arc rod 470 , a plurality of arc rods 470 are provided, and the plurality of arc rods 470 are arranged at intervals in the longitudinal direction and movably fit on the surface of the damper body 100 .

[0047] like Figure 6 As shown, in one embodiment, the first movable plate 610 is provided in an annular plate structure, the inner ring of the first movable plate 610 is provided with an annular groove 612, the piston rod 210 is provided with an annular rib matching the annular groove 612, and is used to limit the first movable plate 610 from moving in the longitudinal direction, and the first movable plate 610 is provided with a plurality of first through holes 611 in an annular array.

[0048] Specifically, the surfaces of the first movable plate 610 and the second movable plate 620 are movably fitted, and a first through hole 611 and a second through hole 621 completely overlap in the longitudinal direction. When the second movable plate 620 rotates, a first through hole 611 at least partially overlaps with a second through hole 621 in the longitudinal direction.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
