Abstract

The invention discloses an invisible door closer which mainly comprises a smooth bore, a connecting plug sliding rod, a return spring, a smooth bore oil plug, a flat pressing oil guide pipe, a speed changing chamber, a speed changing valve and a speed changing chamber oil plug, wherein the smooth bore, the flat pressing oil guide pipe and the speed changing chamber form an integrated structure; the flat pressing oil guide pipe is communicated with two ends of an oil chamber from the outside of the smooth bore oil chamber; a piston part of the connecting plug sliding rod only can slide between two ends of the flat pressing oil guide pipe; the speed changing chamber consists of a cylindrical chamber and a truncated cone-shaped chamber, and the outer diameter of the cylindrical chamber is identical with that of the speed changing valve; the bottom surface radius of the truncated cone-shaped chamber is identical with that of the cylindrical chamber, and the upper surface radius of the truncated cone-shaped chamber is identical with the section radius of the flat pressing oil guide pipe; the speed changing chamber is communicated with the flat pressing oil guide pipe. According to the invisible door closer disclosed by the invention, a traditional external crank arm door closer is changed into a built-in straight arm door closer and can be combined with hinges for mounting; higher uniformity in stress is realized by symmetric mounting; compared with a traditional door closer, the invisible door closer has the advantages that high attractiveness is realized, and the problem about the deformation of a door and a frame after long-time use can be avoided.

Description

A kind of stealthy door closer
Technical field
the present invention relates to onedoor closer, especiallya kind of stealthy door closer.
Background technology
At present, along with the development of housing construction, the use of door closer is more and more extensive, especially use more on security protection door, fire exit door, but current is all door closer of cranking arm mostly, and not only outward appearance is lofty, but also be easy to hang resistance position higher building body, especially in case of emergency, its inconvenience is more obvious.
Summary of the invention
technical problem to be solved by this invention is to providea kind of stealthy door closer, by external for tradition door closer of cranking arm, changes built-in straight-arm door closer into, installation can be combined with hinge, and can be made stressed more even by symmetrical installation, more traditional door closer is both more attractive in appearance, turn avoid the problem on deformation of Long-Time Service back door and frame.
the technical scheme that the present invention solves its technical problem is:a kind of stealthy door closer, mainly comprise smooth bore, connect fill in that slide bar, back-moving spring, smooth bore oil are stifled, concora crush oil guide pipe, throw-over room, throw-over valve and throw-over room oil stifled, described smooth bore, concora crush oil guide pipe and throw-over room are structure as a whole.
The diameter of described even plug slide bar upper piston part is equal with described smooth bore inside diameter, and described smooth bore oil is stifled is tightened in described smooth bore outer end by screw thread.
Described concora crush oil guide pipe is from two ends, external communication grease chamber, described smooth bore grease chamber, and the described piston portion connecting plug slide bar can only slide between described concora crush oil guide pipe two ends.
Described throw-over room is that the truncated cone-shaped chamber that cylindrical chamber with bottom surface radius with cylindrical chamber equal, the upper radius surface equal with described throw-over valve external diameter is equal with described concora crush oil guide pipe section radius is formed, described throw-over room and described concora crush oil guide pipe UNICOM.
Described throw-over valve is cylindrical structural, and center is provided with the coaxial low speed oil-through hole that radius is not more than described concora crush oil guide pipe diameter, and has quick oil-through hole at the scope excircle array being greater than described concora crush oil guide pipe radius.
Described throw-over room oil is stifled to be fastened on described throw-over room by screw mandrel.
the invention has the beneficial effects as follows, compared with prior art, built-inly can install, reach stealthy effect, elegant in appearance, succinct safety, again because it does not need external long cranking arm, therefore symmetrically up and down can install, is conducive to door and frame stress balance, avoid deformation occurs.

Detailed description of the invention
As shown in the figure, a kind of stealthy door closer, mainly comprise smooth bore 1, connect plug slide bar 2, back-moving spring 3, smooth bore oil are stifled 4, concora crush oil guide pipe 5, throw-over room 6, throw-over valve 7 and throw-over room oil stifled 8, described smooth bore 1, concora crush oil guide pipe 5 and throw-over room 6 are structure as a whole.The diameter of described even plug slide bar 2 upper piston part is equal with described smooth bore 1 inside diameter, and described smooth bore oil stifled 4 is tightened in described smooth bore 1 outer end by screw thread.Described concora crush oil guide pipe 5 is from two ends, external communication grease chamber, described smooth bore 1 grease chamber, and the described piston portion connecting plug slide bar 2 can only slide between described concora crush oil guide pipe 5 two ends.Described throw-over room 6 is that the truncated cone-shaped chamber that cylindrical chamber with bottom surface radius with cylindrical chamber equal, the upper radius surface equal with described throw-over valve 7 external diameter is equal with described concora crush oil guide pipe 5 section radius is formed, described throw-over room 6 and described concora crush oil guide pipe 5 UNICOM.Described throw-over valve 7 is cylindrical structural, and center is provided with the coaxial low speed oil-through hole that radius is not more than described concora crush oil guide pipe 5 diameter, and has quick oil-through hole at the scope excircle array being greater than described concora crush oil guide pipe 5 radius.Described throw-over room oil stifled 8 is fastened on described throw-over room 6 by screw mandrel.When people opens the door, pull and describedly connect plug slide bar 2, compress described back-moving spring 3 squeezed fluid force feed and shift to the right, now described throw-over valve 7 moves to right, whole oil-through hole conducting, and door can movement fast; After people leaves, the described plug slide bar 2 that connects does homing action under the effect of described back-moving spring 3, and now described throw-over valve 7 moves to left, and all quick oil-through holes are blocked, and only have the conducting of low speed oil-through hole, door is progressively shut.
