The utility model is characterized in that: a copper auxiliary slide sheet is covered around upper surface of most section for the plastic sliding block toward the tail end of the guide way. The utility model has the advantages of effectively guaranteeing easily processing, well forming well cooperating between the copper auxiliary sliding sheet and the plastic sliding block, being flexible with hard feature, being not easily cracked, wear-resistance, effectively lowering using noise and prolonging service life, having simple structure, being elaborate and having strong practicability.

Description

A kind of new hinges

The utility model relates to the sliding support hinge that a kind of flat opening alumium alloy door and window are used, and belongs to the improvement of component of the doors and windows.

Existing hinge mainly comprises the trailing arm that connects to form the parallelogram framework successively, cantilever, long fulcrum bar, short strut, guide rail and device also can be along the slide blocks of draw-in groove slip in the guide rail draw-in groove, long fulcrum bar wherein, one end of short strut is connected with slide block, cantilever one end is connected with the guide rail tail end, because slide block is generally stainless steel, metal material such as copper, cause the motion of slide block in draw-in groove to have some setbacks, frictional resistance is big, the opening and closing window all relatively consumes power, inconvenient, simultaneously because slide block and draw-in groove etc. adopt metal material simultaneously, cause the direct contact that is metal between each parts composition, in use be easy to generate unpleasant to hear noise and bigger wearing and tearing, occur easily after long-term the use slide block and draw-in groove cooperate unreliable, the get loose phenomenon of beat of generation, thereby reduce the bearing strength and the self-locking property of integral hinge, and make window be difficult to opening and closing, make troubles to use.

The purpose of this utility model provides that a kind of slip is smooth and easy, frictional resistance is little, noise is used in effective reduction, resistance to wear, walk steadily new hinges reliably of rail.

The utility model comprises that the trailing arm, cantilever, long fulcrum bar and the short strut that are movably connected to form the parallelogram framework successively, guide rail and device are in the guide rail card is poor and can be along the slide block made from plastic cement of draw-in groove slip, wherein, one end of long fulcrum bar and short strut is connected with slide block, cantilever one end is connected with the guide rail tail end, it is characterized in that above-mentioned slide block is coated with a copper auxiliary slide plate towards more than half section upper surface of guide rail tail end.

For effectively improve combination between auxiliary slide plate and the slide block closely and solid and reliable, further the assurance slide block is walked the steady and reliable of rail in draw-in groove, above-mentioned auxiliary slide plate both sides have been bent to form two fins respectively downwards, the both sides correspondence of above-mentioned slide block is provided with the caulking groove that can embed this fin, and auxiliary slide plate connects as one by the intercalation and the slide block of its fin and slide block caulking groove.And the tail end of above-mentioned auxiliary slide plate is provided with the rectangular tabs of downward bending, and the tail end of above-mentioned slide block is provided with corresponding breach that can ccontaining this tabs.

The utility model is because employing is provided with copper auxiliary slide vane structure on the plastic cement slide block, effectively guaranteeing copper auxiliary slide plate and plastic cement slide block handling ease between the two, simply, stereotyped, on the basis of no-float, make its first section to be main friction fully with the plastic cement, the weak link of eliminating the slide block caulking groove part of the more than half section in rear portion causes the shortcoming of breaking because of long-term abrasion, and the copper auxiliary slide plate that the more than half section in rear portion is provided with helps to strengthen its hardness, thereby band was hard during the whole sliding part that both are combined into was gentle, be difficult for jackknifing, wear-resistant, both avoided very stiff and demanding contact the between metal slide block and the draw-in groove, reduce its frictional resistance each other, improve the precision of processing, guarantee sliding part draw-in groove to walk rail smooth and easy, steadily, effectively reducing it again uses noise and improves its antiwear property, effectively improve its application life, thereby effectively improve the bearing strength and the self-locking performance of integral hinge, make things convenient for the opening and closing of window.Be provided with the auxiliary slide vane structure of two fins and right angle tabs simultaneously; make auxiliary slide plate and plastic cement slide block body in conjunction with tightr and solid and reliable; thereby make auxiliary slide plate play double protection to the slide block body; the fracture of the plastic cement slide block that had caused when both having avoided the slide block body end to be connected with plastic cement slide block caulking groove with the direct collision of the interior sprue of draw-in groove and with the auxiliary slide plate that stainless steel is made; it is more reliable that slide block body and draw-in groove are cooperated; it is littler to wear and tear; further prolong its application life, and the utility model is simple in structure, ingenious, practical.
