Embodiment
The present invention will be described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention is arranged on the lower section of door 14, and the present invention is fixedly connected with door-hinge.Such as Fig. 2 to Fig. 5 institutes
Show, base 11 is circular metalwork, and some installations being circumferentially uniformly arranged are welded with the circular outer wall of base
Plate 8, on a mounting board provided with screwed hole.Outer barrel 6 is provided with the top of base, as shown in Figure 6, Figure 7, outer barrel is columnar gold
Belong to part, horizontal positioned transverse slat 7 is provided with the inner chamber of outer barrel, transverse slat is the metallic plate of annular, and transverse slat is fixed on outer barrel
On inwall, the inner chamber of outer barrel is divided into upper and lower two independent cavitys by the setting of transverse slat, is provided with screwed hole in the bottom of outer barrel, such as
Shown in Fig. 8, bolt 2 is provided between outer barrel and base, being fixedly connected for outer barrel and base is realized with this.Set at the top of base
There is projection 13, projection is cylindrical structural and is arranged on the center of base.Torsion spring 10 is fixed with projection, in the bottom of transverse slat
Lower bearing end cap 9 has been bolted, has been provided with upper lid 5 in the top of outer barrel, upper lid between outer barrel with being threadedly coupled and upper lid
The good seal between outer barrel, upper lid realize the sealing to outer barrel from top.Axle has been bolted at the top of upper lid
Socket end lid 3, angular contact ball bearing is respectively fixed with top bearing cover and lower bearing end cap, is set between two angular contact bearings
There is damping shaft 1, damping shaft can rotate relative to outer barrel.The lower end of damping shaft is placed in the cavity of bottom after passing through transverse slat, torsion spring
Lower end is fixed in projection, and upper end and the damping shaft of torsion spring are connected.The upper end of damping shaft is placed in axle after passing through top bearing cover
The top of socket end lid, the upper end of damping shaft are fixedly connected with door-hinge, and during installation, base, outer barrel are placed under earth's surface, upper lid with
Earth's surface is concordant.Sector is fixed with the damping shaft in upper chamber is placed in makees motion block 12, makees to set respectively on motion block each
There is through hole, liquid can unidirectionally be moved provided with check valve 15, the setting of check valve in through-holes.It is provided with upper chamber
A pair of dividing plates 4, two dividing plates are located on same perpendicular, and two dividing plates and two make motion block and upper chamber are divided into four oil pockets,
Fill fluid respectively in each oil pocket, and the oil pocket for making motion block both sides is connected together by check valve.
When opening the door, damping shaft rotates clockwise with one piece of rotation of door, damping shaft, can drive and make motion block synchronous axial system, this
When make the motion of motion block opposed separators, in two oil pockets separated as motion block, the fluid in one of oil pocket passes through a list
Another oil pocket is flowed to valve.Now because torsion spring and damping shaft are connected, torsion spring deforms with the unlatching of door, when cancelling on the door
Active force after, the reset of damping shaft can be driven in the presence of torsion spring.Due to now being rotated counterclockwise as motion block, fluid is not
It can be entered by check valve by an oil pocket in adjacent oil pocket.Damping slot 16 is provided with the top for making motion block, now by start
In two oil pockets that block separates, the fluid in one of oil pocket is entered in another oil pocket by damping slot, is produced with this
Damping force, realize buffering on the door.
