Description
Technical field
The utility model relates to hinge technical field, particularly relates to clean automatic door-closing hinge.
Background technology
Along with social development, the kind of hinge is also more and more, to meet the demand that people are different, at present, in dust-free workshop or laboratory in order to ensure clean, the first scheme is hinge and use of door closer, time can automatically close the door to reach turnover, prevent that to greatest extent dust from entering, but this mode exists certain drawback equally, door closer is conventionally fixing between door and doorframe by screw, so in clean, dust in door closer groove is not easy cleaning, cause the accumulation of a large amount of dusts, be unfavorable for indoor clean and tidy, do not reach the requirement in dust-free workshop or laboratory, first scheme is to adopt clean hinge, although clean hinge extensive use and field, toilet, structure and mounting means have not laying dust, feature easy to clean, but without door closer, buffering, the function of location, in the process using, there is drawback equally, unfavorable promoting the use of, exist deficiency.
In sum, for the defect of prior art, need especially clean automatic door-closing hinge, to solve the deficiencies in the prior art.
Utility model content
Can not meet the demand of toilet for hinge in prior art, bring certain deficiency to actual production, the utility model proposes clean automatic door-closing hinge, novel in design, by nested clean hinge on automatically closed axle core, can meet the demand of automatic door-closing, again can easy cleaning dust, Practical Performance is excellent, to address the deficiencies of the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
Clean automatic door-closing hinge, comprise automatic closed axle core, one side of automatic closed axle core is nested with door leaf hinge, the opposite side of automatic closed axle core is nested with doorframe hinge, door leaf hinge and doorframe hinge are the trapezoidal of surrounding smooth excessiveness, above door leaf hinge, offer the tapping hole of connection door, above doorframe hinge, offer the tapping hole that connects doorframe, between door leaf hinge and doorframe hinge, be provided with seal washer.
All can be around automatic closed axle core Rotate 180 degree at door leaf hinge described in the utility model and doorframe hinge.
Further, two tops of described automatic closed axle core are all provided with the block sealing.
Further, described automatic closed axle core includes spring, oil cylinder, the angle of door leaf and doorframe is 0 degree-80 degree, under the pulling force that door leaf produces at spring torsional deformation, form the automatic closed area of door leaf, the angle of door leaf and doorframe is greater than 80 degree, and the tension force that the distortion that door leaf produces spring is greater than spring forms door leaf positioning area.
The beneficial effects of the utility model are: this product structure is simple, can be arranged on quickly and easily the inside, toilet, have reduced the installation of door closer simultaneously, therefore reduced the place of gap and laying dust, can accomplish comprehensive cleaning, and have door closer and hinge function concurrently, save cost, automatic closed axle cored structure makes it have again door closer, buffering, the function of location, Practical Performance is excellent, modern design, is a kind of well innovation scheme, has very much marketing prospect.
Brief description of the drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is Facad structure schematic diagram of the present utility model.
Fig. 2 is side structure schematic diagram of the present utility model.
The automatic closed axle core of 10-in figure, 20-door leaf hinge, 30-doorframe hinge, 40-block, 50-seal washer, 60-tapping hole.
Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, Fig. 2, clean automatic door-closing hinge, comprise automatic closed axle core 10, one side of automatic closed axle core 10 is nested with door leaf hinge 20, the opposite side of automatic closed axle core 10 is nested with doorframe hinge 30, and door leaf hinge 20 and doorframe hinge 30 are the trapezoidal of surrounding smooth excessiveness, and door leaf hinge 20 offers the tapping hole 60 of connection door above, doorframe hinge 30 offers the tapping hole 60 that connects doorframe above, between door leaf hinge 20 and doorframe hinge 30, is provided with seal washer 50.
In addition, door leaf hinge 20 and doorframe hinge 30 all can be around automatic closed axle core 10 Rotate 180 degree.Two tops of automatic closed axle core 10 are all provided with the block 40 sealing.Automatic closed axle core 10 includes spring, oil cylinder, the angle of door leaf and doorframe is 0 degree-80 degree, under the pulling force that door leaf produces at spring torsional deformation, form the automatic closed area of door leaf, the angle of door leaf and doorframe is greater than 80 degree, and the tension force that the distortion that door leaf produces spring is greater than spring forms door leaf positioning area.
In the process of installing, door leaf hinge is aimed at the interlayer of door leaf inner hollow, use screw to be connected with door leaf by tapping hole, doorframe hinge is aimed at the interlayer of doorframe inner hollow, use screw to be connected with doorframe by tapping hole, so just can make door and doorframe effectively tighten together, after screw lock, the side of door leaf and doorframe all has the groove staying while installation, at this moment use baffle plate to be inserted in door leaf and the reserved slot of doorframe side, can make groove block completely, screw while installation like this is just enclosed in the interlayer in the middle of doorframe and door leaf completely, can't see from the outside the vestige of any screw, avoided staying dead angle when clean, installation can complete easily like this, in the process using, the angle of door leaf and doorframe is that 0 degree-80 are while spending, door leaf can cut out automatically, in the process of closing, the angle of door leaf and doorframe cushions to door leaf between 15 degree-45 degree, when buffering course is spent to 0-15, relative velocity is very fast, until closed, the flexibility ratio using is large, the angle of door leaf and doorframe is greater than 80 while spending, door leaf is normally open, can meet the different needs, in clean, because door leaf hinge and doorframe hinge are the trapezoidal of surrounding smooth excessiveness, so door leaf hinge and all do not have gap above doorframe hinge, can clean it easily, Practical Performance is excellent.
The utility model produce effect into: simple in structure, can be arranged on quickly and easily toilet the inside, reduced the installation of door closer simultaneously, therefore reduced the place of gap and laying dust, can accomplish comprehensive cleaning, and have door closer and hinge function concurrently, save cost, automatic closed axle cored structure makes it have again door closer, buffering, the function of location, Practical Performance is excellent, modern design, is a kind of well innovation scheme, has very much marketing prospect.
The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
