Description
Technical field
The utility model relates to a kind of labeled door, is specifically related to a kind of self closing device of labeled door.
Background technology
Labeled door is existing indispensable fireproofing under construction, there is fire prevention, every cigarette, suppress fire spread, protect the special role of evacuating personnel, it is widely used in the intensive public place of the personnel such as business and public building.In the time that fire occurs, the fireproof performance that labeled door utilizes self material to possess, thus reach the effect that stops fire spread, for ensureing the security of the lives and property, implement fire-fighting fire extinguishing and strive for the quality time.
Because the shutoff device of existing labeled door is all to coordinate labeled door to cut out by the door closer that is arranged on labeled door top, door closer has in use not only affected the switch angle of labeled door, has also affected the overall appearance of labeled door simultaneously.In addition, due to loaded down with trivial details, the fragile distortion of fire safety poor performance, particularly hinge of labeled door construction, often there is rod member and come off in door closer, and door-plate is pulled off damage, makes fire-proof function premature failure, even can cause unexpected casualty accident, causes the consequence that is difficult to expectation.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of self closing device of labeled door, and the intensity that reaches labeled door is high, and can realize and automatically closing and the object of locating.
The technical solution of the utility model is:
A kind of self closing device of labeled door, comprise hinge body, hinge body comprises the main shaft of a hollow and is located at sheet under the hinge upper slice of main shaft both sides, hinge, the inside of described main shaft is provided with a torsion spring, the two ends of described torsion spring are connected with upper and lower fixed block respectively, and the end of described upper and lower fixed block is fixed in respectively the two ends of main shaft with screw thread fixed block; The outside of described hinge upper slice is installed with fastening devices, described fastening devices comprises horizontal draw-in groove, and the centre of described draw-in groove is provided with rolling steel ball, and the upper/lower terminal of draw-in groove is respectively equipped with spring, one end of described spring is connected with draw-in groove, and the other end is fixed by screws in hinge upper slice; Under described hinge, on sheet, be installed with the fixing paddle fastening with described rolling steel ball.
Further, fixed piece is cylinder, and its bottom offers the groove for embedding torsion spring termination; The sidepiece of upper fixed block is provided with adjustment screw perpendicular to the direction of described groove.
Further, the outer wall of described lower fixed block is the hexagonal structure matching with main shaft inner chamber, and its upper end offers the groove for embedding torsion spring termination.
The utility model is fixed on main shaft inside by upper and lower fixed block by torsion spring, and the end of upper and lower fixed block is fixed in respectively the two ends of main shaft with screw thread fixed block, prevents that upper and lower fixed block from moving up and down or ejecting along main shaft.Labeled door open angle hour, under the elastic force effect of torsion spring, can be automatically closed.Avoid, on the top of labeled door, door closer is installed and realized automatically closing of labeled door, saved cost, also beautified the overall appearance of labeled door simultaneously.
In addition, hinge volume of the present utility model is relatively large, and its stabilized structure and not yielding or damage has improved the useful life of labeled door.
Due to fixing device for installing on hinge upper slice, under hinge, on sheet, fixing paddle is installed in relevant position, when in case of emergency, the door leaf of labeled door is opened to maximum angle, makes sheet under its hinge with hinge upper slice laminating, fixing paddle be engaged with rolling steel ball, fixing paddle is to outside thrust of draw-in groove, and spring in fastening devices is under resilient force, all apply a reaction force to draw-in groove, fixing paddle is engaged more firm with rolling steel ball, door leaf is fixed on this position.Thereby people can be passed through fast, avoid closing and affecting people and pass through because of door leaf, improved the safety in use procedure.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure: 1-hinge upper slice, 2-main shaft, sheet under 3-hinge, 4-screw thread fixed block, the upper fixed block of 5-, 6-adjustment screw, 7-torsion spring, 8-fixes paddle, fixed block under 9-, 10-screw, 11-spring, 12-rolling steel ball, 13-draw-in groove.
Detailed description of the invention
As shown in Figure 1, a kind of self closing device of labeled door, comprise hinge body, hinge body comprises the main shaft 2 of a hollow and is located at sheet 3 under the hinge upper slice 1 of main shaft both sides, hinge, the inside of described main shaft 2 is provided with a torsion spring 7, the upper end of described torsion spring 7 embeds in the groove of columniform upper fixed block 5, upper fixed block 5 sidepieces are provided with adjustment screw 6 perpendicular to the direction of described groove, the lower end of torsion spring 7 embeds in the groove of lower fixed block 9, and the outer wall of lower fixed block 9 is the hexagonal structures that match with main shaft 2 inner chambers.The end of upper fixed block 5, lower fixed block 9 is fixed in respectively the two ends of main shaft 2 with screw thread fixed block 4; The outside of described hinge upper slice 1 is installed with fastening devices, described fastening devices comprises horizontal draw-in groove 13, the centre of draw-in groove 13 is provided with rolling steel ball 12, the upper/lower terminal of draw-in groove 13 is respectively equipped with spring 11, one end of described spring 11 is connected with draw-in groove 13, and the other end is fixed on hinge upper slice 1 by screw 10; Under described hinge, on sheet 3, be installed with the fixing paddle 8 fastening with described rolling steel ball 12.
