Description
Technical field
The present invention relates to a kind of door closer device, specifically a kind of hydraulic door closing apparatus, belongs to mechanical protection technical field.
Background technology
Along with the progress of society.The development of science and technology.People are also more and more higher for the consciousness of building safety, and door closer has become the very important execution part of of modern architecture intelligent management.Common or traditional employing at present be a kind of door shutter with springs directly utilizing the elastic force effect of spring, this kind of door closer volume is large, quality weight, main shortcoming is that impact force when to close is large, when particularly having to select the spring compared with noticeable effort when not wishing a speed of closing too slow, especially there is the problem that when to close, impact force is large, and when to close, because effect of inertia can make the movement velocity of door excessively fast, and often make people have little time to avoid, produce larger impact sound at door turn-off transient simultaneously.Due to the unstability of spring, door closer was often lost efficacy.
The present invention is different from traditional door closer; reach cushioning effect by carrying out throttling to the liquid in door closer; the core of hydraulic door-closer design philosophy is to realize the control to door closing procedure; the various functional parameters of door closing procedure are regulated according to human needs; door not only can be closed by the present invention automatically, can also available protecting doorframe and door body.There is good economic benefit and social benefit, be applicable to promoting the use of.
Summary of the invention
Advantages such as having problems for above-mentioned prior art, the invention provides a kind of machine hydraulic door closing apparatus, have compact conformation, long service life, it manufactures, install, dismantle, maintenance is all very convenient, solves Problems existing in background technology.
For achieving the above object, the technical solution used in the present invention is: a kind of hydraulic door closing apparatus, comprises speed-regulating valve of locking, described in speed-regulating valve side of locking hydraulic oil main channel is set; Side, described hydraulic oil main channel arranges and closes a speed-regulating valve; A described speed-regulating valve side of closing arranges hydraulic oil duplex channel and hydraulic oil duplex channel is connected with hydraulic oil main channel; Described hydraulic oil duplex channel side arranges return valve and return valve one end is in hydraulic oil duplex channel inside; Described return valve bottom arranges spring; Described spring side arranges one way valve and spring one end and one way valve close contact; Described one way valve side arranges gear and wheel and rack is connected with a joggle; Described tooth bar top arranges piston.
Further, locking described in, to be arranged at hydraulic oil main channel inner in speed-regulating valve one end.
Further, described wheel and rack is connected with a joggle and gear can rotate on tooth bar.
Further, described spring carries out Tension and Compression under the rotation of gear.
Further, described rocking arm is rectangular structure and one end is fixedly connected with gear.
The invention has the beneficial effects as follows:
1, compact conformation, application life is of a specified duration;
2, manufacture, install, dismounting, maintenance all very convenient;
3, door can be closed automatically, the various functional parameters of door closing procedure can regulate according to human needs, can available protecting doorframe and door body.

Fig. 1 is overall structure schematic diagram of the present invention;
In figure: 1, speed-regulating valve of locking, 2, hydraulic oil main channel, 3, closes a speed-regulating valve, 4, gear, 5, hydraulic oil duplex channel, 6, return valve, 7, spring, 8, one way valve, 9, rocking arm, 10, tooth bar, 11, piston.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.Obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, a kind of hydraulic door closing apparatus, comprises speed-regulating valve 1 of locking, described in speed-regulating valve 1 side of locking hydraulic oil main channel 2 is set; Side, described hydraulic oil main channel 2 arranges and closes a speed-regulating valve 3; A described speed-regulating valve 3 side of closing arranges hydraulic oil duplex channel 5 and hydraulic oil duplex channel 5 is connected with hydraulic oil main channel 2; Described hydraulic oil duplex channel 5 side arranges return valve 6 and return valve 6 one end is in hydraulic oil duplex channel 5 inside; Described return valve 6 bottom arranges spring 7; Described spring 7 side arranges one way valve 8 and spring 7 one end and one way valve 8 close contact; Described one way valve 8 side arranges gear 4 and gear 4 and tooth bar 10 are connected with a joggle; Described tooth bar 10 top arranges piston 11.
As optimisation technique scheme of the present invention: described in lock that to be arranged at hydraulic oil main channel 2 inner in speed-regulating valve 1 bottom; Described gear 4 is connected with a joggle with tooth bar 10 and gear 4 can rotate on the rack gear 10; Described spring 7 carries out Tension and Compression under the rotation of gear 4; Described rocking arm 9 is rectangular structure and rocking arm 9 one end is fixedly connected with gear 4.
The operating principle of this novel door closer is: when opening the door, the action of door body drivening rod, and travelling gear 4 is rotated, tooth bar 10 plunger is driven to move to the right, the process moved to right at plunger 7 springs of being hit by a bullet are compressed, hydraulic oil in right chamber also pressurized, one way valve 8 spheroid on the left of plunger is opened under the effect of oil pressure, hydraulic oil in right chamber flows in left chamber through one way valve 8, after door opening process completes, because spring 7 is compressed in opening process, the elastic potential energy put aside is released, plunger to be turned left thruster, band nutating gear 4 and door closer rocker arm 9 rotate, make a closedown.In spring dispose procedure, because the hydraulic oil in the left chamber of door closer is compressed, one way valve 8 is closed, hydraulic oil can only be flowed out by the gap between housing and plunger, and the aperture runner on plunger is back to right chamber, and therefore hydraulic oil constitutes resistance to spring 7 release, namely the effect of buffering is reached by throttling, to make the speed of closing be under control, closing a speed-regulating valve 3 and can regulate on valve body, can control different rows journey section, transformablely close a speed.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present invention; not in order to limit the present invention, every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solution of the present invention.
