Detailed Description

Further description is provided below in connection with the accompanying drawings.

Referring to fig. 1, a window sealing strip is hollow and includes a connecting portion 1, a contact portion 2, two first extrusion deformation portions 3, and at least one second extrusion deformation portion 4. The whole window sealing rubber strip is produced and manufactured by an extruder in cooperation with a corresponding die, and all the parts are integrally formed.

The connecting portion 1 is intended for a fixed connection with the window edge. Namely, referring to the existing window sealing rubber strip, a layer of back rubber is arranged on the first outer wall 11 of the connecting part 1, a coating film on the back rubber is torn off, and the sealing rubber strip is fixedly connected to the window edge through bonding; some aluminum alloy window frame edges can be reserved with clamping grooves, and the first outer wall 11 of the connecting part 1 is integrally provided with a matched clamping part, so that the fixed connection of the two parts can be completed. The inner wall of the connecting portion 1 is integrally provided with two first protrusions 12.

And one ends of the two first extrusion deformation parts 3 are respectively and integrally connected to two sides of the connecting part 1, and the other ends of the two first extrusion deformation parts 3 are respectively and integrally connected to two sides of the contact part 2, so that the cross section of the sealing rubber strip is closed and corresponds to a hollow shape. The contact part 2 is used for supporting the frame of the window when the window is closed, namely, before the window is completely closed, the contact part 2 of the sealing rubber strip on the edge of the window firstly contacts the frame, then the sealing rubber strip is extruded along with the further complete closing of the window, and the two first extrusion deformation parts 3 deform to enable the contact part 2 to be attached to the frame.

In one embodiment, the contact portion 2 is preferably circular arc shaped for facing outwards against the second outer wall 21 of the frame. Compared with the second outer wall 21 of the contact part 2 which is in a plane and is in a circular arc shape, the contact part 2 is in line contact with the frame firstly, then the contact part 2 is subjected to preliminary extrusion deformation, and is in surface contact with the frame, and finally the two first extrusion deformation parts 3 deform, so that the contact part 2 is attached to the frame, and the matching is more complete and tight.

The inner wall of the contact portion 2 is integrally provided with two second protrusions 22, and the two second protrusions 22 and the two first protrusions 12 are in one-to-one correspondence with each other with a space left therebetween. The spacing is reserved between the first bulge 12 and the second bulge 22, so that the first bulge 12 and the second bulge 22 do not influence the extrusion sealing rubber strip, the first extrusion deformation part 3 deforms, and meanwhile, after the first bulge 12 and the second bulge 22 are propped against each other, the deformation degree of the first extrusion deformation part 3 is limited, and the service life is ensured. The two first pressing deformations also form a plug-in position 7 with the first projection 12 and the second projection 22 on the same side.

The second press-deformed portion 4 is L-shaped and is disposed between the connecting portion 1 and the contact portion 2, and also within the two first protrusions 12, 22. Namely, when the first extrusion deformation part 3 deforms in the extrusion sealing rubber strip, the second extrusion deformation part 4 also deforms, so that the subsequent restoring capability and the service life of the sealing strip are improved. In addition, if the above-described "the contact portion 2 is used to be in the outwardly circular arc shape against the second outer wall 21 of the frame", the second press-deformed portion 4 is also press-deformed at the time of preliminary press-deformation of the contact portion 2.

In one embodiment, the second press-deformed portion 4 is one, two bifurcated first ends 41 are connected to the contact portion 2, and the second ends 42 are connected to the connection portion 1.

Referring to fig. 2, in another embodiment, two second press deformation portions 4 are provided, and second ends 42 of the two second press deformation portions 4 are connected to each other to form an X shape.

Referring to fig. 3, a window generally needs four sealing strips, and at four corners of the edge of the window, the ends of the two sealing strips are cut to form an inclined shape of 45 degrees. When the second extrusion deformation portion 4 is separated from the connecting portion 1 and the contact portion 2, a section of sealing rubber strip with a proper length is cut in advance, and the second extrusion deformation portion 4 of the section of sealing rubber strip is peeled off, scissors can be adopted, preferably, the first connection position 5 of the second extrusion deformation portion 4 and the connecting portion 1, and the second connection position 6 of the second extrusion deformation portion 4 and the contact portion 2 are in an inward concave state, so that the second extrusion deformation portion 4 is conveniently peeled off manually.

The two plugging sections of the second extrusion part are respectively matched with the corresponding plugging positions 7 in the two sections of sealing rubber strips. Therefore, the stability of the joint strip at four corners of the edge of the window is improved, in addition, the joint strip can be combined into a rectangular frame shape through the second extrusion part, and then the joint strip is connected to the window, so that the joint at the four corners is ensured.

For the four corners, if the first crush-deformed portion 3 is inward, it may hit the second crush-deformed portion 4 inserted, affecting the crush deformation of the joint strip at the four corners. Therefore, it is preferable that the two first press-deformed portions 3 have an outwardly circular arc shape. Such that the two first press-deformed portions 3 are ensured to be deformed outwardly at the time of press-deformation.
