Description

A kind of filter screen that has framework

[technical field]

The utility model relates to a kind of filter screen, more particularly is that a kind of strainability is good, intensity is good, connects the filter screen that has framework easy to use.

[background technology]

The existing filter screen that is used to filter usefulness, such as being used for the initial cycle water filtration, also being useful on the filtering oil smoke of smoke exhaust ventilator and the filtering of central air-conditioning air outlet impurity and dust etc., it is embedded in the framework around the filter screen, all is mostly to adopt four sections mouldings that have a groove to combine to form a quadrangle.Since all need between the moulding of each section to connect, whole framework and insecure, loosening easily distortion.Especially (such as aluminium, sponge etc.) during softer, the deformable of the material of being inlayed by framework use (looking the needs of dismounting) after a period of time, and loosening distortion will appear in the filter screen of being inlayed, and serious also can be toward coming off; When the framework that is inlaid with filter screen in bearing certain pressure, framework twists easily even can damage.

For solving above-mentioned existing problem, the utility model is made useful improvement.

[utility model content]

The purpose of this utility model is in order to overcome the prior art deficiency, and provide a kind of intensity good, connect reinforcement shape framework easy to use.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposal:

A kind of filter screen that has framework, include filter screen and be trapped among filter screen framework all around, described framework is made by the moulding that has U type groove, described moulding includes first side, second side and base, it is characterized in that: described framework be by the whole piece moulding after the bending of a plurality of bending parts, head and the tail couple together and the polygon ring frame that forms;

Described a kind of filter screen that has framework is characterized in that: an end of described moulding is provided with the hole, is provided with at the other end of moulding the hole is fastened the profile that the head and the tail two ends are coupled together;

Described a kind of filter screen that has framework is characterized in that: the top of described first and second side is also inwardly turned up respectively and is formed first and second relative flanging, staggers mutually in the position of described first flanging and second flanging;

Described a kind of filter screen that has framework is characterized in that: the cross section on described base is a concave surface;

Described a kind of filter screen that has framework, it is characterized in that: the side of the bending part of described moulding is respectively equipped with V-notch, the inclination angle of first hypotenuse of described V-notch is bigger than the angle of second hypotenuse, and the root of second hypotenuse extends to form one section straight flange downward vertically and is connected with the root of first hypotenuse.

The utility model compared with prior art has following advantage:

Because the utility model adopts whole framework to surround filter screen, so surround the framework of filter screen, whole framework only connects in the place of head and the tail, so framework can tightly couple together, not yielding and scatter, the filter screen that is arranged on wherein also can be out of shape, thereby can not influence the filtering function of filter screen; Also have the concave surface that is shaped as owing to cross section, framework bottom surface, the flanging of formation is also inwardly turned up on the last top that adds two sides more respectively, so strengthened the deformation-compensated ability of framework in progressive formation greatly; There is the position of first flanging and second flanging to stagger mutually again, thus dual-side mutual staggered positions when the clamping filter screen, thus avoid the extruding on two side tops, so filter screen can be held tighter; Also have at last because the bending part of two sides of whole moulding is provided with the different hypotenuse in inclination angle respectively, so very firm of the framework that couples together.

[specific embodiment]

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

A kind of filter screen that has framework, include filter screen 1 and be trapped among filter screen 1 framework 2 all around, described framework 2 is made by the moulding 3 that has U type groove, described moulding 3 includes first side 4, second side 5 and base 6, described framework 2 be by the whole piece frame after 7 bendings of a plurality of bending parts, end at described moulding 3 is provided with hole 8, the other end at moulding 3 is provided with the profile 9 that hole 8 is fastened, hole 8 and profile 9 make the polygon ring frame that couples together from beginning to end and form, this profile 9 puts in bending again in the hole 8, profile 9 is close on the base 6, thereby it is loose that this framework is not easy.The top of described first and

second side

4,5 is also inwardly turned up respectively and is formed first and second flanging 10,11, stagger mutually in the position of described first flanging 10 and second flanging 11, so it is when the clamping object, thereby avoid flanging 10,11 extruding between the two, so object can be held tightlyer, prevent from that object from having to come off; There is described first side 4 inwardly to turn up again and forms flanging 10,11, so strengthened the warping resistance ability of moulding 3 greatly with the top of second side 5.

The base 6 of described moulding 3 is toward recessed, make its cross section form an inner concave, strengthened effect end dual-side deformation-compensated in progressive formation, the side of described moulding 3 bending parts 7 is respectively equipped with V-notch, the angle at first hypotenuse, 12 inclinations angle of described V-notch is bigger than the angle at second hypotenuse, 13 inclinations angle, and the root of second hypotenuse 13 extends to form one section straight flange 14 downward vertically and is connected with the root of first hypotenuse 12.When moulding 3 is turned up the polygon ring frame of formation, at bending part 7 places, adjacent first side 4 abuts against together mutually, adjacent second side 5 also abuts against together mutually, described straight flange 14 abuts against with the base 6 of moulding 3, makes the anti-loosening of whole framework and keeps the ability of shape to strengthen greatly.

In sum, the utility model adopts whole moulding to form a framework, there is the cross section, bottom surface of moulding to adopt arcwall face again, two sides of moulding adopt the design of mutual staggered positions in addition, V-notch at the moulding place adopts the unique design method at last, and intensity of the present utility model is strengthened greatly, the warping resistance ability is good, it is loosening to be difficult for, can bear bigger characteristics such as pressure thereby make.
