Description

The tenslator of automatic hinge
Technical field
The present invention relates generally to a kind of automatic hinge, and it is installed on automatic door or the labeled door so that just can open door easily with a very little power when pushing, and is closed lentamente to the doorstep by the restoring force of spring when unclamping.The present invention relates more specifically to a kind of elastic controller of automatic hinge, and it uses the helical spring elasticity of worm gear control torque, thereby fast, easily and critically controls its elasticity.
Background technology
Usually, the labeled door that automatic door is widely used in the space in the protective door also is used for other door to prevent or the spreading of the intensity of a fire that slows down, and therefore an available very little power is opened Men Bingke easily and closed automatically and lentamente and call.
Such function is finished by the automatic hinge than lower part that is installed in door.As shown in Figure 1, this automatic hinge comprises a cylindrical shell 1,2, one a moment of torsion helical spring 3 and an elasticity control assembly 4.This axle 2 axially is installed in the housing 1, and this moment of torsion helical spring 3 is installed on the axle 2, and this elasticity control assembly 4 is placed in the upper end of moment of torsion helical spring 3 and forms a plurality of elasticity control holes 5 regularly on its external peripheral surface.On the sidewall of housing 1, form an opening so that elasticity control hole 5 is exposed to the outside by this opening, one latch 6 by opening be inserted in movably in the elasticity control hole 5 with these elasticity control assembly 4 brakings in an end arranged side by side position of this elasticity control hole 5 with this opening, therefore keep a modulated elastic force of this spring 3.One hydraulic pressure speed is regulated parts and is connected to the upper end of axle 2 and the rotary speed of Control Shaft 2.
The switching speed that in door, needs control gate behind this automatic hinge of installation sometimes.Be the switching speed of control gate, have the elasticity of the elasticity control assembly 4 necessary rotations of elasticity control hole 5 with control torque helical spring 3.
When needing the elasticity of control torque helical spring 3, the user inserts anchor clamps elasticity control hole 5 and makes its rotation reach a predetermined elasticity value up to this spring 3, and then, latch 6 is inserted into elasticity control hole 5 with braking elasticity control assembly 4.But the elasticity of control torque helical spring 3 difficulty relatively by this way, and need control the elasticity of this moment of torsion helical spring 3 energetically, in addition, the spacing between the elasticity control hole 5 is bigger, elasticity that therefore can not accurate control torque helical spring 3.
Summary of the invention
Correspondingly, the present invention considers the problems referred to above that occur in the prior art, and the elastic controller that the purpose of this invention is to provide a kind of automatic hinge, it uses the helical spring elasticity of worm gear control torque, thereby can fast, easily and critically control its elasticity.
For achieving the above object, the invention provides a kind of elastic controller of automatic hinge, comprise that a cylindrical shell, axially is installed in axis of rotation in the housing, and is installed in said moment of torsion helical spring bottom is connected to axis of rotation with the cylindrical shape tension force control assembly, of the tension force of controlling this spring upper end with moment of torsion helical spring from back stretch to this axis of rotation that apply, in the mode that is arranged on the spring below and regulates parts with the hydraulic pressure speed of the rotary speed of controlling this around being installed on the said axis of rotation.Wherein the tension force control assembly forms integral body with spring in the top.Wherein elastic controller comprises that one is installed on the lower end worm gear on every side of tension force control assembly, with be installed on the housing bottom corresponding with the installation site of worm gear with the worm gear engaged worm, the handle hole that worm screw has an end that is formed at it to be to allow user's rotary worm, therefore can be along with the rotation of worm gear and worm screw the tension force of control spring.
Description of drawings
Above-mentioned purpose of the present invention and other purpose, feature and advantage will appreciate that clearlyer in the following detailed description with accompanying drawings.Wherein:
Fig. 1 is the phantom drawing of existing automatic hinge;
Fig. 2 is the structure sectional view of automatic hinge elastic controller of the present invention; And
Fig. 3 is the side sectional view of automatic hinge elastic controller of the present invention.
The specific embodiment
Referring now to accompanying drawing, wherein used identical reference numerals is represented same or analogous parts in all different accompanying drawings.
As shown in Figures 2 and 3, automatic hinge of the present invention is vertically mounted in the hinge seat of 19a bottom.This automatic hinge comprises that a cylindrical shell 10 and that surrounds automatic hinge components is positioned at the bottom of housing 10 and with the support 11a of screw nail on door 19a, housing 10 has held one 12, a hydraulic pressure speed adjusting parts, a moment of torsion helical spring 13 and an elasticity control assembly 14, this axle 12 can be independent of housing 10 rotations, this hydraulic pressure speed is regulated parts and is connected to the upper end of axle 12 and the rotary speed of Control Shaft 12, this moment of torsion helical spring 13 be installed in the axle 12 on to apply restoring force to it, this elasticity control assembly 14 is installed in the lower end of moment of torsion helical spring 13.
One pinion 18a be installed in this lower end of 12 and with pinion 18b interlock, this pinion 18b is installed in the upper end of the hinge axis 20 that is arranged in doorframe 19b, reference numerals 11b represents to be installed to doorframe 19b to support the support of hinge axis 20.
This elasticity control assembly 14 have that a worm gear 15 and that is connected to the lower end of moment of torsion helical spring 13 is installed in the housing 10 in case with the screw rod 16 of worm gear 15 interlocks.
Door 19a, is formed a handle hole 17 at this ends of 16 of screw rods and contacts the axle of this screw rod 16 and use spanner or screwdriver to rotate this axle to allow the user so that the axle head of this screw rod 16 is exposed to the outside by the part amputation.
This moment of torsion helical spring 13 is reversed when opening of the present invention 19a, and when unclamping 19a, close automatically at the elastic force effect Xiamen 19a of moment of torsion helical spring 13, this external hydraulic pressure speed that is connected to axle 12 upper ends is regulated parts effect Xiamen 19a and is slowly closed.
When needs control applies the elasticity of moment of torsion helical spring 13 of restoring force to axle 12, the user in handle hole 17, inserts spanner or screwdriver with rotating screw bolt 16 spool.
Like this, the rotation of screw rod 16 is rotated worm gear 15, and the rotation of worm gear 15 also makes the axle 12 that combines with it rotate, therefore can be fast and reverse easily or loosen moment of torsion helical spring 13 with increase or reduce the elastic force of spring 13.
As mentioned above, the invention provides a kind of elastic controller of automatic hinge, its use one with the screw rod of worm gear interlock and when allowing the user need increase or reduce the helical spring elasticity of moment of torsion by the handle hole rotating screw bolt, thereby can be easily with the elasticity of a little power control spring, and make door have good surface appearance owing to having only handle hole to be exposed to the outside.
Though disclose its preferred embodiment for the present invention will be described, those skilled in the art will be understood that and do not deviating from the present invention under the situation of the scope and spirit of additional claims that various modification, increase and replacement are possible.
