Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

The utility model provides a window screening fixed profile, includes the gland section bar 2 of being connected with window frame section bar 1, be equipped with first indent 3, second indent 12 on the window frame section bar 1, be equipped with pressure head 4 on the gland section bar 2, pressure head 4 impresses layering 5 in the first indent 3, be equipped with compression roller 13 in the second indent 12, between layering 5 and the first indent 3, it has window screening 6 to press between compression roller 13 and the second indent 12, be connected through card strip 7 between window frame section bar 1 and the gland section bar 2, the side of gland section bar 2 is equipped with and is used for improving the shield 8 of pressure head 4 dustproof ability, gland section bar 2, shield 8, pressure head 4, card strip 7 are one shot forming's overall structure.

The pressing strip 5 is an adhesive tape with a U-shaped radial section, the pressing head 4 is of a clamping tongue-shaped structure, and the pressing head 4 is embedded into the pressing strip 5 and is in interference connection with the pressing strip 5.

The U-shaped space surrounded by the pressure head 4, the clamping strip 7 and the gland profile 2 forms a cutting cavity 9, and the tail end of the window screen 6 is positioned in the cutting cavity after being cut.

The outer side of the U-shaped structure of the pressing strip 5 is in interference connection with the first pressing groove 3.

The compression roller 13 is provided with saw teeth 14 distributed annularly.

The side of window frame section bar 1 be equipped with draw-in groove 10, the convenience that card strip 7 agrees with mutually the sled of gland section bar 2 dismantles a little 11, be equipped with on the card strip 7 with the breach that the sled some 11 agrees with mutually, sled some 11 embedding breach department on the card strip 7, draw-in groove 10, first indent 3 do 1 to the sunken rectangle recess that forms of window frame section bar, sled some 11 with window frame section bar 1 is one-time manufacturing fashioned overall structure.

During installation, the window screen 6 is firstly flatly laid on the window frame section bar 1, the screen cutting is completed according to the required size, the area of the screen cutting is slightly larger than that of the window frame, enough window screen can be pressed into the first pressing groove 3 and the second pressing groove 12 after the screen stretching is ensured, then the pressing roller 13 is pressed into the second pressing groove 12, the window screen is preliminarily fixed, the pressing strip 5 is pressed into the first pressing groove 3, and the edge of the window screen 6 can be pressed into the first pressing groove 3 to complete the screen stretching.

The design of the press roller 13 and the second press groove 12 can further increase the firmness of the installed window screen for all window screens. Meanwhile, the problem that the stretching stress on the middle part and two ends of a reel is uneven in the yarn stretching process is solved, and the specific process is as follows: in the process of tightly pressing the yarn stretching frame, the tightening force of the yarn stretching frame is gradually increased from the end point to the middle part, the edge type variable of the yarn stretching frame is smaller, the middle type variable is larger at the initial stage of yarn stretching, the yarn stretching is not uniform, the middle part of the yarn stretching frame deforms and narrows, and the frame body deforms; through the structural design of the elastic sawteeth 14 of the press roller 13, the sawteeth 14 are firstly embedded into the screen holes, and the point contact friction between the screen and the inner wall of the second press groove is directly converted into the line surface contact between the window screen 6 and the elastic press roller 15, so that the contact area is increased, and the screen stretching is completed; because of whole cloth cover window screening atress in the pre-pressing yarn in-process, guarantee that both ends and the middle part of screen frame are unanimous at the intermediate variable of pressing the yarn in-process, especially to metal window screening, polyester gauze, protection class gauze, its gauze hardness is great, difficult quilt compresses tightly the deformation, if directly adopt layering 5 to compress tightly, can be collapsed by metal window screening and open, and compression roller 13 presses the window screening for the arc structure, and the sawtooth around it can be better imbed in the yarn hole, make it more firm with what second indent 12 was hugged closely.

After the tightening, the installation of the cover pressing section bar 2 is completed, specifically, the pressing head 4 is aligned to the U-shaped structure of the pressing strip 5 and then pressed down, at the moment, the pressing strip 5 can be further tensioned, so that the window screen 6 is fixed more firmly, meanwhile, the pressing strip 7 can be embedded into the clamping groove 10 until the prying point 11 is matched with the notch of the pressing strip 7, and meanwhile, the dust strip 8 compresses the window screen 6, so that the two parts of the dust strip 8 and the window frame section bar 1 are respectively contacted, and the sealing performance is improved.

When gland section bar 2 need be dismantled, in the gap between prying point 11 and the card strip 7 is embedded into to hand or instrument, stir outward, can easily dismantle gland section bar 2, can clear up inside the section bar this moment or to window screening 6 maintenance operations such as straining again, change, washing.

No matter the installation or the dismantlement process, layering 7, window frame section bar 1 all can produce certain deformation, nevertheless all in the deformation range of section bar metal, can all form regular plane and right angle structure after the installation, can not influence the appearance and the use of section bar.

Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
