Door closer multifunctional axial core described in the utility model, supportingly only this multifunctional axial core need be installed on hinge endoporus when hinge uses, hinge just can be made to have, and hydraulic cushion closes a function, door stops positioning function, without the need to installing door closer additional in addition, for ease of maintenaince change, modern society can be met to security needs.
Door closer multifunctional axial core described in the utility model, the course of work is as follows:
1, when compression spring axial retrogressing position-limit mechanism 2 is in compression spring lock-out state, this in-house compression spring is in elastic force accumulated state, and this mechanism does not contact with piston 15 upper surface, and the energy of the compression spring of accumulation of energy cannot be delivered to piston, then:
During rotary middle spindle 3, axially slide the piston 15 of joining with it and also follow rotation, the skewed slot (spiral chute) of piston 15 pipe shaft sidewall slides along slide-bar 20 and sliding sleeve 19, and piston produces rotation and adds axially-movable, but now piston is without being stressed, so the angle of central axis stops arbitrarily.Facilitate vertical door closer to produce, assemble.
2, when compression spring axial retrogressing position-limit mechanism 2 is in compression spring released state, this in-house compression spring is in elastic force release conditions, and this mechanism can contact with piston 15 upper surface, and the energy of the compression spring of accumulation of energy can be delivered to piston, then:
During enabling:
Along with rotary middle spindle 3, axially slide the piston 15 of joining with it and also follow rotation, the skewed slot of piston 15 pipe shaft sidewall slides along slide-bar 20 and sliding sleeve 19, and piston produces rotation and adds axially-movable, and piston is compressive pressure spring energy-storage upwards;
Meanwhile, in piston 15 motion process, interlock piston cap 17 endoporus slides along the vertebra degree shaft of function point analysis mechanism 1 lower end, and shoe cream room 35 space diminishes, then the hydraulic oil of shoe cream room 35 flows to pressurized oil pocket 36 by one way valve 18;
When hydraulic cushion closes:
Along with rotary middle spindle 3, axially slide the piston 15 of joining with it and also follow rotation, when piston 15 follow central axis make the skewed slot on piston contact with slide-bar 20 time, compression spring can promote piston and move down along skewed slot, along with moving down of piston, piston, simultaneously also along helicla flute rotary motion, makes central axis 3 follow piston 15 and rotates, in piston 15 motion process, interlock piston cap 17 endoporus slides along the vertebra degree shaft of function point analysis mechanism 1 lower end;
The volume of pressurized oil pocket 36 from the gap between the vertebra degree shaft and piston cap 17 endoporus of function point analysis mechanism 1 lower end, slowly flows to shoe cream room 35 with the hydraulic oil in descending reduction, the pressurized oil pocket 36 gradually of piston.
By rotating function governor motion 1, the position of the vertebra degree shaft of adjustable function governor motion 1 lower end, the vertebra degree shaft changing function point analysis mechanism 1 lower end by this inserts longitudinal degree of depth of piston cap 17 endoporus, realization is to the adjustment of the gap length between the vertebra degree shaft of function point analysis mechanism 1 lower end and piston cap 17 endoporus, namely the change of this gap length is the flow that the hydraulic oil changing pressurized oil pocket 36 flows to shoe cream room 35;
Increase if increase gap hydraulic fluid flow rate, then piston movement speed is fast,
Reduce if reduce gap hydraulic fluid flow rate, then piston movement speed is slow.
Thus the speed that speed, namely control centre's axle that can realize the downward axially-movable of control piston rotate, thus realize the adjustment of a speed of closing.
Function point analysis mechanism 1 and the axial concrete structure retreating position-limit mechanism 2 of compression spring can with reference to this enforcements of existing skill, and non-the application's emphasis, body function describes in detail, therefore no longer describes in detail.
The content be not described in detail in this manual belongs to the known prior art of professional and technical personnel in the field.
