Description

Convenient universal layering for screen window

The utility model discloses the general press strip of a kind of convenient type window screening, belong to door and window part technical field, the screen window gauze (window screening) that is mainly used on fixing any door and window can be used to the plastic sheeting that the fixed sealing door and window is used winter.

Modal wooden screen window in prior art, its gauze all are to adopt elongated batten to compress with on first ailing usually; The steel door and window of Xing Qiing in recent years, its steel screen window then adopts the steel plate bar to compress, and is screwed.Having occurred magnetic window screening press strip on the market, Shanghai in 1992 is by magnetic attraction press strip to be pressed on the steel sash.Above-mentioned three kinds fixedly the mode of window screening all have separately weak point: press the time-consuming expense of taking a lot of work of dismounting window screening to expect with batten, torn open the difficulty, nail gets rusty even does not tear open not get off, tear open often the screen window frame fragile, simultaneously press not firmly, be subjected to external force to do the time spent and very easily come off because of the mooring points platen press; The steel screen window easily gets rusty, and be difficult for to change window screening, and it also belongs to a pressure type in addition, presses not firmly, and window screening easily comes off and is difficult to reparation; Magnetic window screening press strip, pressure is little, and the cost height can only be used for the steel door and window, and the easily loss of excitation of back that gets rusty is not durable.Mostly to be slideway plug-type for aluminium alloys and plastic window in addition, and above-mentioned three kinds of screen windows are all inapplicable.

It is a kind of simple in structure that the purpose of this utility model is to provide, cost is low, save material, be convenient to dismounting, be convenient to timely cleaned and changed gauze, gauze is stressed is evenly pressed firmly, difficult drop-off, wooden, steel, aluminium alloys or plastic door-window all can be general, also can be used to the general press strip of convenient type window screening of the plastic sheeting of fixing seal door and window winter.

According to drawing formula especially, pulling force with twine body angle, the number of turn this basic principle that is directly proportional, at the subject matter that exists in the prior art, basic design of the present utility model is: adopt the rectangular tenon (press strip) of doing of a kind of elastic body, with gauze embed on the kerve lath with the corresponding vallecular cavity of the shape of above-mentioned tenon in, by means of pressure and frictional force the gauze periphery is squeezed in vallecular cavity, this kerve lath screw, unit's nail or adhesive are on the screen window frame or on the window jamb, thus the realization purpose of design.

The general press strip of described convenient type window screening that is characterised in that of the present utility model is made of elastic layering and kerve lath two parts; Above-mentioned elastic layering is that to have or do not have the cylinder bodily form of mushroom head above one rectangular or prismatoid is rectangular, the raw material that it can have big friction factor by Weather-resistant in single or compound elastomeric material or the metal material and surface through extrude, mold pressing, draw or vulcanize, foaming, cooling forming; When adopting non-metallic elastic material to make, can be with metallic framework also can not be with metallic framework in it, its shape also can take other any up-narrow and down-wide geometrical bodies rectangular, so that gauze compressed and be convenient to dismounting; Above-mentioned kerve lath for have above it with above-mentioned elastic layering remove above it with the mushroom head after shape corresponding and than the bigger special-shaped vallecular cavity of press strip and to be positioned at the rectangle of screw of this vallecular cavity bottom rectangular, its material can be metal, timber or duroplasts, on it with the cavity geometry of vallecular cavity become with the shape of above-mentioned elastic layering, the shape of the two is always corresponding, to guarantee that the two is embedded cooperation, the above-mentioned screw of its vallecular cavity bottom is not essential, sometimes, then with screw or unit's nail, when no, then above-mentioned kerve lath is fixed on the screen window frame or directly is fixed on the window jamb with adhesive, after flattening window screening above it above-mentioned elastic layering is embedded in the above-mentioned vallecular cavity and can be squeezed in the gauze periphery in the vallecular cavity, gauze is fastened; When pulling down gauze, as long as above-mentioned elastic layering one end is levered up and it is pulled out in vallecular cavity.

The utility model has the advantages that have only an elastic layering and a kerve lath composition simple in structure, and make easily, save material, cost is low, easy installation and removal is convenient in time clean and change gauze, and the gauze periphery is stressed evenly, press firmly, difficult drop-off, the gauze face is smooth attractive in appearance, and the screen window of any material and form of structure can be general, also can not establish the screen window frame, directly the kerve lath is fixed on the frame of window, opens the part gauze during switch sash and get final product, in addition, also can be used to the plastic sheeting of fixing seal door and window, one-object-many-purposes winter.

Accompanying drawing 1 is one of the utility model most preferred embodiment, the vertical cross-sectional schematic cross-section of assembly, and Fig. 2 cuts open schematic diagram, 1 elastic layering (tenon) among the figure, 2 kerve laths, 3 special-shaped vallecular cavities, 4 screws, 5 gauzes (window screening), 6 screen window frames for back office is installed.

Elastic layering 1 adopts butadiene rubber, is sulfided into the rectangular tenon formula of the cylinder bodily form press strip of band mushroom head in this embodiment, Cylinder section diameter 4mm, and a mushroom Breadth Maximum 10mm, maximum height 8mm is the tapering at 60 ° of angles between mushroom head and the cylinder; Kerve lath 2 employing polyvinyl chloride filling rigid plastics are squeezed into the rectangle strip kerve lath with special-shaped vallecular cavity and screw, wide 10mm, thick 7mm, the vallecular cavity shape is corresponding with above-mentioned elastic layering 1, its cross section is the circle of diameter 4.4mm, the top is cut one and is arc, and the wide 4mm horn mouth of opening opening width is 90 ° of angles.Screw φ 2.

Change as present embodiment:

1, elastic layering 1 can be with the mushroom head, promptly makes simple cylinder or top for the plane;

2, elastic layering 1 and kerve lath 2 raw material, shape, overall dimensions etc. all can adapt to change, but the shape of elastic layering must be corresponding with the vallecular cavity shape on the kerve lath;

3, the bottom cut board installation site and the mode of fixedlying connected with screen window frame or window jamb thereof can suitably change according to inhomogeneous door and window.
