Reducing gear is located in upper interlayer, and second gear engages with first gear and the 3rd gear simultaneously；
Described torque spring energy store mechanism 5 includes the torsion spring 4 being arranged on an axle, one end of torsion spring be arranged in upper interlayer
Limited post 13 connect, the other end of torsion spring contacts with being arranged on an axle limiting plate 14；
Described damping reducing gear includes installing internal friction disc 7 on the rotary shaft, and internal friction disc is symmetrically arranged with three
Individual groove, is provided with a brake pad 8, is provided with external friction ring 6 outside internal friction disc in each groove, and described external friction ring is solid
Dingan County is contained in upper interlayer, and the lower end of internal friction disc is fixed with ratchet 9, and the correspondence position of described rotary shaft is provided with ratchet 10,
Ratchet is coordinated with the ratchet on ratchet.
The present invention relates to a kind of centrifugal rate controlling door closer-holder, specifically a kind of energy that will store when opening the door
The acceleration obtaining after being changed is converted to door closer-holder at the uniform velocity.Belong to energy technology field.
In conjunction with Fig. 1-Fig. 3, the present invention includes two connecting rods 12 and 1, copper post 2, change-speed gearing group (first gear 31, second
Gear 32 and the 3rd gear 33 (namely accelerating gear)), torque spring energy store mechanism and damping reducing gear 5；Described fixed frame master
To be made up of copper post and three poly (methyl methacrylate) plates；Described door closer-holder is encapsulated by fixed frame, and connecting rod is door closer-holder and door body
Connection member, except all parts of two connecting rods are all arranged on inside organic glass frame, fixed by copper post 2.Wherein, second
One end of connecting rod 1 connects door body frame by first connecting rod 13, and the other end of second connecting rod 1 uses concentric shafts to connect torque spring energy store machine
Structure and change-speed gearing group, change-speed gearing group connects torque spring energy store mechanism 4 and damping reducing gear 5, and accelerating gear passes through axle and resistance
Buddhist nun's reducing gear 5 is coaxially connected.Described damping reducing gear 5 is mainly by internal friction disc 7, brake pad 8, ratchet 9, ratchet 10 and rotation
Rotating shaft 11 forms.
Torque spring energy store mechanism and damping reducing gear 5 are located in the poly (methyl methacrylate) plate folder of upper strata, and change-speed gearing group and acceleration
Gear is located in lower floor's poly (methyl methacrylate) plate folder.Torque spring energy store mechanism is located at the centre position of connecting rod 1 and first gear 31, by making
Complete to fix with an axle 15.
External friction ring 7 in the damping reducing gear 5 installed has certain thickness, and rotary shaft 11 fixes internal friction disc 7
And ratchet mechanism, the movement locus of the trapezoidal shape groove restriction brake pad 8 simultaneously cutting out inside internal friction disc 7, subtracted by damping
Ratchet 10 positioning in fast mechanism 5 makes the brake pad 8 of internal friction disc 7 not work when opening the door.Rely in damping reducing gear 5 and rub
Its energy stores in torque spring energy store mechanism, during closing door, and is discharged by the centrifugal force of cleaning block 8 and frictional disk 7
Close a speed to control.And ratchet 10 positioning passing through in door opening process to damp in reducing gear 5 makes the brake pad in frictional disk 7
8 do not work.
Above-mentioned brake pad 8 material is copper.
In conjunction with Fig. 4, according to the principle of friction eceleration, using the removable brake pad 8 being arranged in internal friction disc 7 with rub outward
Wipe the friction of ring 6, reach fall Slow Close door speed.By torque spring energy store mechanism storage energy during enabling, subtracted using damping when closing door
In fast mechanism 5, brake pad 8 completes to close a retarded motion.Due to not needing damping reducing gear 5 to work when opening the door, only closing
Men Shicai needs damping reducing gear 5 to work, thus employs unidirectional internal friction formula ratchet in damping reducing gear 5, so
Just accomplish during enabling, not changing door speed, damping reducing gear 5 only adds to torsion spring compressive tension generation when cutting out door
Speed is passed through damping reducing gear 5 and is converted at the uniform velocity.
In conjunction with Fig. 5, during installation, internal friction disc 7 and ratchet outer ring are coaxially fixed together, rotary shaft 11 and internal friction disc 7
Fix with one heart, because ratchet has one-directional rotation characteristic, therefore when opening the door, ratchet outer ring does not rotate, only the spine in the ratchet when closing door
Pawl 10 is blocked rear internal friction disc 7 high-speed rotation by the ratchet of ratchet 9, and brake pad 8 is in the drive that runs up of frictional disk 7 simultaneously
Under, the brake force of the centrifugal force that produce brake pad 8 and the frictional force synthesis needs producing with internal friction disc 7, realize at the uniform velocity closing
The effect of door.
Specifically the fixed frame of the present invention is fixed three poly (methyl methacrylate) plates by eight copper posts and is formed, wherein connecting rod position
In the outside of poly (methyl methacrylate) plate, torque spring energy store mechanism and damping reducing gear are located in the poly (methyl methacrylate) plate interlayer of upper strata, gear teeth
Wheel group and accelerating gear are located in lower floor's poly (methyl methacrylate) plate interlayer.
Torque spring energy store mechanism mainly comprises torsion spring, the spacing aluminium sheet of scale and an axle, and the fixing scale in side of torsion spring is spacing
Plate, specifically spacing aluminium sheet, the foreign steamer of opposite side next-door neighbour's damping reducing gear, and fixed by limited post 13, such both sides
All play the position-limiting action of torsion spring 4, torque spring energy store mechanism is located at the centre position of second connecting rod and first gear, by using one
Number axle 15 completes to fix.
Accelerating gear is located at change-speed gearing group and the middle link position of damping reducing gear.
External friction ring in damping reducing gear has certain thickness, and rotary shaft fixes internal friction disc and ratchet mechanism,
Cut out three trapezoidal grooves simultaneously inside internal friction disc, limit the movement locus of three brake pads, by damping in reducing gear
Ratchet positioning so that the brake pad in frictional disk is not worked in door opening process.
