Abstract

The invention relates to a novel door closing speed governing hinge device converted from the field of hardware. The novel door closing speed governing hinge device is technically characterized in that mechanical friction generates running-in damp speed governing to obtain an automatic door closing speed governing hinge; the pressure intensity of a fixed rectangle outer disc sleeve shaft and a balance spring is adjusted with a speed governing screw by movable and fixed rectangle inner-out disc friction disc sheets through a connecting column shaft, a speed governing screw, a steel ball, the balance spring, movable and fixed rectangle inner-out disc sleeve shaft core shafts and the movable and fixed rectangle inner-out disc friction disc sheets, the movable and fixed rectangle inner-out friction disc sheets generate the pressure intensity running-in damp effect, and the function of speed governing is achieved. Under the clutch effect, a door leaf hinge is separated within the range from 10 degrees to 15 degrees to achieve the rapid door closing effect of a door.

Description

Automatic door-closing speed-regulating hinge

Technical field:

Automatic door-closing speed-regulating hinge of the present invention (hinge) to relate on a kind five metals category basis transform and the automatic door-closing speed-regulating hinge formed, some enterprises of recent domestic successively develop a kind of novel door closer-holder, there are title hinge closer, automatic door-closing hinge, close an arrangements for speed regulation, in any case address, its feature is all close a speed-regulating function, uniting by this technology is could produce by torsion spring hinge connected effect to close an effect, and we are called automatic door-closing speed-regulating hinge in a word.

Background technology:

At present, the door hinge device that closes produced both at home and abroad differs from one another, but is all by hydraulic method speed governing, by piston rod and piston relative motion, utilize speed governing to cut down and control oily flow thus reach adjustment to close a speed object and form, its shortcoming is that its technology acuracy requirement of hydraulic method is high, manufactures extremely difficulty, and discrete is complicated, seal request is strict, and rubber o-ring oil sealing is easy to wear and form leakage of oil, once leakage of oil makes speed-regulating function lose efficacy, be equal to ready-made hinge and use.Automatic door-closing speed-regulating hinge object of the present invention is to solve above technical deficiency, the device of automatic door-closing speed regulation is realized with mechanical friction speed-regulating scheme, this case technology be a kind of with mechanical friction speed-regulating scheme to realize the device of automatic door-closing speed regulation, this case technology is with friction disc inside and outside sound rectangle, speed adjustment screw, steel ball, balance platen, balancing spring, regulate sound rectangle internal and external disk sleeve mandrel, rectangle friction disc inside and outside sound is made to produce Pressure effects, and realize governing speed function, close door hinge technically to compare its speed governing object be identical with other, but the technology of the present invention has, structure is simple, technique is convenient, cost reduces, mechanical speed governors, there is not the advantages such as leakage of oil.

Invention content:

Automatic door-closing speed-regulating hinge technical solution technical scheme that problem adopts of the present invention is: at doorframe pipe page, door leaf pipe page, connect axis of a cylinder, speed adjustment screw, static moment shape outer disk sleeve, static moment shape external friction disc, dynamic rectangle inner disc mandrel, dynamic rectangle inside friction disc, balance platen, balancing spring, bearing, outer sleeve in clutch apparatus, middle sleeve, interior axle, Roller Shaft, relevant cooperation, it is characterized in that: agree with two pipe page upper end tube chambers by doorframe pipe page door leaf pipe page and be set with connection axis of a cylinder, speed adjustment screw, connect two pipe pages and agree with that to lock two pipe page the relation between motion and rest doorframe pipe pages by alignment pin be static page, door leaf pipe page is dynamic page, static moment shape outer disk sleeve arranges in the wall of door leaf pipe page chamber, connecting axle lower end, static moment shape outer disk sleeve upper end symmetric angle elongated slot embeds can be up and down when alignment pin makes speed adjustment screw regulate, dynamic rectangle inner disc mandrel is nested with in static moment shape outer disk sleeve, friction disc inside and outside folded equipped sound rectangle between diaxon rectangular channel, by balancing spring, speed adjustment screw is regulated and produce pressure, dynamic rectangle inner disc mandrel lower end groove axle is put in bearing and clutch apparatus and is overlapped convex axle shaft coupling, clutch device is set in the tube chamber of doorframe pipe page door leaf pipe page lower end, two pipe page the relation between motion and rest are locked by alignment pin, clutch apparatus acts on two pipe page clutch functions, depart from when door leaf page closes when door is spent to 10-15, make door leaf pipe page Rapid door closer.The invention has the beneficial effects as follows, structure is simple, and cost reduces, and mechanical speed governors, does not deposit leakage of oil, has innovative technology and new model structure, is different from any one automatic door-closing hinge.

Accompanying drawing illustrates:

Below in conjunction with drawings and Examples, the present invention will be further described
