Description

Technical Field

[0001] The utility model relates to the technical field of rubber strips, in particular to an airtight structure for occlusal sealing of doors and windows. Background Art

[0002] The rubber strip is made of rubber and is usually used on building door and window components: the joints between glass and moldings, glass and frame and sash, frame and sash, sash and sash, etc. It can prevent the leakage or intrusion of internal and external media (rain, air, dust, etc.), and can prevent or reduce the damage caused by mechanical vibration and impact, thereby achieving the effects of sealing, sound insulation, heat insulation and shock absorption. It is an elastic strip or rod-shaped material.

[0003] For example, the patent with authorization announcement number CN221298931U provides an installation structure for a glass partition wall and a double-faced partition wall, wherein the sealing strip is provided with a pressure-bearing portion of an annular closed structure and an installation portion slidably installed on a frame.

[0004] When this type of sealing strip is subjected to the clamping force between the door panel and the door frame, the force-bearing part is only the pressure-bearing part, and there is no pressure buffer structure. When the pressure-bearing part is frequently subjected to pressure, the pressure-bearing part is very likely to be subjected to the entire pressure between the door panel and the door frame, resulting in reduced durability of the pressure-bearing part, which affects the durability of the sealing strip. Utility Model Content

[0005] The utility model addresses the problem that the durability of existing sealing strips is reduced because the pressure-bearing portion is subjected to the full pressure between the door panel and the door frame. The technical problem to be solved by the utility model is to provide an airtight structure for door and window bite sealing that can effectively improve the durability of the strips.

[0006] The technical solution adopted by the utility model to solve the above technical problems is: an airtight structure for door and window bite sealing, comprising a rubber strip fixed on an outer frame or a plate, and the rubber strip is hollow;

[0007] The rubber strip is provided with a pressure-bearing edge capable of pressure contact, and a contact edge that fits the outer frame or the plate;

[0008] A first deformable edge capable of bending and deforming is connected between one end of the contact edge and the pressure edge, or the contact edge is connected to one end of the pressure edge, and a second deformable edge capable of bending and deforming is connected between the other end of the contact edge and the pressure edge;

[0009] The rubber strip is provided with a plurality of oblique edges, one end of the oblique edge is connected to the contact edge and away from the first deformable edge, and the other end is connected to the second deformable edge. The angle between the oblique edge and the contact edge toward the compressed edge is an obtuse angle.

[0010] A further preferred solution of the present invention is that: a mounting groove is provided on the outer frame or the plate body, and the rubber strip is fixed in the mounting groove.

[0011] A further preferred solution of the present invention is that the installation groove is open on both sides, and the contact edge fits the groove wall of the installation groove and is fixedly installed by gluing.

[0012] A further preferred solution of the present invention is that an extension angle is provided on the rubber strip, and the extension angle is located at the connection between the compressed edge and the deformed edge 1, or the connection between the deformed edge 2 and the contact edge, or the connection between the deformed edge 1 and the contact edge, or the connection between the compressed edge and the contact edge.

[0013] A further preferred solution of the present invention is that the extension angle of the connection between the second deformable edge and the contact edge or the connection between the first deformable edge and the contact edge contacts the groove wall of the installation groove or extends out of the installation groove.

[0014] A further preferred solution of the present invention is that the outer frame is fixedly installed, and the plate body is rotatably or slidably installed relative to the outer frame, and the angle is set toward the sliding or rotating direction of the plate body.

[0015] A further preferred solution of the present invention is: the hypotenuse-separated cavity is divided into a pressure cavity and a stable cavity, the pressure cavity is a cavity between the pressure edge, the hypotenuse, the first deformation edge and a part of the contact edge, and the stable cavity is a cavity between the hypotenuse, the second deformation edge and another part of the contact edge.

[0016] A further preferred solution of the present invention is that the contact edge is in an L-shaped structure, and the L-shaped structure of the contact edge is retained on another part of the contact edge.

[0017] A further preferred solution of the present invention is that the first deformable side can be deformed to be concave or convex into the pressure chamber, and the second deformable side can be deformed to be concave or convex into the stabilizing chamber.

[0018] Compared with the existing technology, the advantage of the present invention is that, through the arrangement of the pressure edge, contact edge, deformable edge one, deformable edge two and oblique edge on the rubber strip, when the pressure edge is under pressure and in contact, the deformable edge one and the deformable edge two can buffer the pressure on the pressure edge by deformation, thereby sharing part of the pressure acting on the rubber strip, thereby improving the durability of the rubber strip.

[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0027] This embodiment mainly describes an airtight structure for door and window bite sealing that can effectively improve the durability of the rubber strip, as follows:

[0028] like Figure 1-2As shown, an airtight structure for bite sealing of doors and windows includes a rubber strip 1, which is hollow inside. The rubber strip 1 is provided with a pressure edge 11, a deformable edge 12 connected to one end of the pressure edge 11, a deformable edge 2 13 connected to the other end of the pressure edge 11, a contact edge 14 connecting the deformable edge 12 and the deformable edge 2 13, and a hypotenuse 15 connecting the contact edge 14 and the deformable edge 2 13, wherein the pressure edge 11, the deformable edge 12 and the deformable edge 2 13 can be deformed due to pressure, and the angle between the hypotenuse 15 and the contact edge 14 toward the pressure edge 11 is an obtuse angle, and the arc-shaped mouth of the pressure edge 11 is set toward the angle. Preferably, one end of the pressure edge 11 can be connected to the contact edge 14.

[0029] The interior of the bevel 15 separating rubber strip 1 is a pressure chamber 16 and a stable chamber 17. The pressure chamber 16 is a chamber between the pressure edge 11, the bevel 15, the deformable edge 12 and a part of the contact edge 14, while the stable chamber 17 is a chamber between the bevel 15, the deformable edge 2 13 and another part of the contact edge 14. In this embodiment, the contact edge 14 is an L-shaped structure, and the L-shaped structure of the contact edge 14 is retained on the other part of the contact edge 14.

[0030] The rubber strip 1 is provided with an extension angle 18 , which is located at the connection between the first deforming edge 12 and the contact edge 14 , the connection between the second deforming edge 13 and the contact edge 14 , or the connection between the pressure edge 11 and the first deforming edge 12 .

[0031] like Figure 1-4 As shown, in order to distinguish the rubber strips 1 on the installation components, the rubber strip 1 installed on the outer frame 2 is the first rubber strip 1a, and the rubber strip 1 installed on the plate body 3 is the second rubber strip 1b. The outer frame 2 is a door frame or a window frame, and the outer frame 2 is fixed to a wall, etc., and the plate body 3 is a door panel or a window body, and the plate body 3 is rotatably installed on the outer frame 2. Preferably, the outer frame 2 and the plate body 3 can also be slidably installed, and the plate body 3 can slide relative to the outer frame 2.

[0032] In this embodiment, a mounting groove 21 is provided on the outer frame 2, and the first rubber strip 1a is attached to the groove wall of the mounting groove 21 through the contact edge 14, and a mounting groove 32 is provided on the plate body 3, and the second rubber strip 1b is attached to the groove wall of the mounting groove 32 through the contact edge 14. The first rubber strip 1a and the second rubber strip 1b can be fixedly installed by gluing or the like, and the angle of the first rubber strip 1a on the outer frame 2 is toward the direction of rotation or sliding of the plate body 3, and the angle of the second rubber strip 1b on the plate body 3 is toward the direction of the outer frame 2.

[0033] The mounting groove 1 21 and the mounting groove 2 32 are provided with openings on both sides. The extension angle 18 at the connection between the deformable edge 12 and the contact edge 14 on the first rubber strip 1a, and the extension angle 18 at the connection between the deformable edge 12 and the contact edge 14 on the second rubber strip 1b extend out of the notch of the mounting groove 1 21, and the extension angle 18 at the connection between the deformable edge 12 and the contact edge 14 on the second rubber strip 1b extends out of the notch of the mounting groove 2 32. The extension angle 18 at the connection between the deformable edge 13 and the contact edge 14 on the second rubber strip 1b fits in contact with the groove wall of the mounting groove 2 32. The extension angle 18 at the connection between the pressure edge 11 and the deformable edge 12 on the first rubber strip 1a contacts the plate body 3 or the extension angle 18 at the connection between the deformable edge 12 and the contact edge 14 on the second rubber strip 1b.

[0034] When the plate body 3 rotates to fit the outer frame 2, the pressure edge 11 of the second rubber strip 1b fits and exerts pressure on the pressure edge 11 of the first rubber strip 1a, and the pressure edge 11 is deformed and recessed into the pressure cavity 16, and the oblique edge 15 is inclined toward the stabilizing cavity 17. The deformable edge 12 can be deformed to be recessed into or protruded from the pressure cavity 16, and the deformable edge 2 13 can be deformed to be recessed into or protruded from the stabilizing cavity 17.

[0035] In the present application, the pressure-bearing edge 11, the contact edge 14, the deformable edge 12, the deformable edge 2 13 and the oblique edge 15 are arranged on the rubber strip 1, so that when the pressure-bearing edge 11 is under pressure and contact, the deformable edge 12 and the deformable edge 2 13 can buffer the pressure on the pressure-bearing edge 11 by deformation, thereby sharing part of the pressure acting on the rubber strip 1, thereby improving the durability of the rubber strip 1.

[0036] When the frame and the plate are close to each other and a finger is placed between the frame and the plate, the structural setting of the rubber strip 1, i.e. the presence of the pressure chamber and the stabilizing chamber on the rubber strip 1, enables the rubber strip to contact the finger in advance when the frame and the plate are close to each other, thereby providing a reminder and effectively preventing the finger from being pinched.

[0037] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the product of the present invention is usually placed when in use.
