Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
Shown in Fig. 1~Fig. 6, the slow regulating mechanism of the door closing hinge includes the upper down tube page that top tube and down tube are integrated
Piece, middle pipe hinge 2, hinge pin bar 4 and torsional spring 5 include upper tube 1 and down tube 3 in upper down tube hinge, and the lower part of hinge pin bar 4 is in
2 phase of pipe hinge is fixed, and torsional spring 5 is sleeved on 4 outer wall of hinge pin bar, and lower end and 4 phase of hinge pin bar of torsional spring 5 are fixed, installation in the down tube 3
There is lower helical gear 6, lower screw rod 7 is installed in down tube 3, lower screw rod 7 is meshed with lower helical gear 6, and lower helical gear 6 can be because of lower spiral shell
Bar 7 rotates and rotates, slided up and down because hinge pin bar 4 rotates, and screw thread connects between the lower end of the hinge pin bar 4 and lower helical gear 6
It connects, is set on hinge pin bar 4 there are two upper friction plate 8, the upper end of down tube 3 is equipped with the lower friction plate 9 that can be slid up and down, and hinge pin bar 4 passes through
Friction plate 9 is worn, disc spring 10 is equipped between lower friction plate 9 and lower helical gear 6.Due to taking above-mentioned technical proposal, pass through
Screw rod 7 makes lower helical gear 6 move up or move down under rotation, and the elastic force of multigroup disc spring 10 increaseds or decreases, in turn
So that the frictional force between upper friction plate 8 and lower friction plate 9 is increased or reduced, achievees the effect that slowing down door leaf delays quick-closing door.Due to
4 lower end of hinge pin bar is threadedly coupled with lower helical gear 6, and opening helical gear 6 at present in door leaf can move down, and then reduce dish type
The elastic force of spring 10, closing helical gear 6 at present in door leaf can move up, and the elastic force of disc spring 10 is stepped up, to reach
Door leaf is stepped up the purpose of the frictional force between upper friction plate 8 and lower friction plate 9 when easily pushing away open and close door when opening the door, real

Casting lug thereon 91 can stop that door leaf closes door, play the role of door and stop.At closing time, after upper friction plate 8 crosses casting lug thereon 91
It unclamps, door leaf automatic door-closing under the action of torsional spring 5, first quick and back slow, when finally soon latching, upper friction plate 8 enters groove
In 92, the frictional force between upper friction plate 8 and lower friction plate 9 becomes smaller, and closes power and increases suddenly, realizes fast powerful and enters lock.
It is in 90 ° of angles between the casting lug thereon 91 and groove 92.Door leaf can realize that door stops after opening 90 °.
The casting lug thereon 91 and groove 92 are two, and casting lug thereon 91 can exist with groove 92 with two upper friction plates 8
Designated position matches.Two casting lug thereons 91 are symmetrical arranged, and two grooves 92 are also symmetrical arranged, and casting lug thereon 91 is with groove 92 in spy
Positioning is set corresponding with two upper friction plates 8 on hinge pin bar 4, is reached door and is stopped and strongly close requirement into lock.
The hinge pin bar 4 is equipped with the shaft shoulder 41, and upper friction plate 8 is embedded in the lower face of the shaft shoulder 41.The shaft shoulder 41 and hinge pin bar 4
Design is structure as a whole, and is easily installed, and holding tank is opened up on the lower face of the shaft shoulder 41, in order to which upper friction plate 8 is installed.
9 outer wall of lower friction plate is equipped with axial straight trough 93, and the inner wall fixing pin 11 of down tube 3, pin 11 is located at axial
In straight trough 93.Lower friction plate 9 can be slided up and down along 3 inner wall of down tube, to adjust rubbing between upper friction plate 8 and lower friction plate 9
Wipe power.
Steel ball 12 is equipped between the upper tube 1 and middle pipe hinge 2 and between middle pipe hinge 2 and down tube 3.12 energy of steel ball
Enough reduce between upper tube 1 and middle pipe hinge 2 and the frictional resistance between middle pipe hinge 2 and down tube 3, reduces the opening force of door leaf
With the load-bearing to door leaf.
