All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-7.

Example 1:

the embodiment provides a sealing rubber strip 1 for an outward opening door and window, which comprises the following components: a strip support body 11 having a first connection surface and a second connection surface; wherein, the first connecting surface is provided with a connecting part 13, and the connecting part 13 is used for being connected with the outward opening door and window sash body section bar structure 3; wherein the second connection surface is provided with a sealing portion 12, the sealing portion 12 comprising a first seal 121 and a second seal 122; wherein the first sealing member 121 is configured to form a first sealing structure with the first sealing mating member 21 configured by the out-opening door and window frame profile structure 2 when the window closing operation is performed; wherein the second sealing member 122 is configured to form a second sealing structure with the second sealing mating member 22 configured by the out-opening door and window frame profile structure 2 when the window closing operation is performed.

In the section door and window structure, the section door and window structure can be divided into a openable section and a fixed section according to whether the section can be opened. Typically, the same opening will have a combined structure of a part of the split fans, another part of the fixed fans. In order to allow the profile structure to exhibit integrity, it is generally necessary to allow the profile base frames of the opening and fixing wings to be shared, which forms the frame structure of the door and window. The frame structure is firstly installed at the opening and is connected and fastened with the wall body/the building. The opening structure also comprises two parts, one part is an outward opening door and window frame section bar structure 2 connected with the frame body, and the other part is an outward opening door and window frame section bar structure connected with the outward opening door and window frame section bar structure 2 (usually) through hardware (such as a sliding support).

The sealing rubber strip 1 for the outward opening door and window provided by the embodiment is a sealing rubber strip arranged between the frame profile structure 2 of the outward opening door and window and the frame profile structure 3 of the outward opening door and window, and is connected with the frame profile structure 3 of the outward opening door and window through the sealing rubber strip 1 for the outward opening door and window, so that the sealing rubber strip 1 for the outward opening door and window moves along with the frame profile structure 3 of the outward opening door and window when the outward opening door and window are opened and closed, and the sealing rubber strip 1 for the outward opening door and the frame profile structure 2 of the outward opening door and window form a first sealing structure and a second sealing structure when the outward opening door and window are closed, so that the sealing rubber strip is convenient to install and replace, and the overall sealing performance is improved.

Specifically, the connecting part 13 of the first connecting surface of the adhesive tape supporting body 11 is connected with the external door and window frame profile structure 3, and the sealing part 12 of the second connecting surface of the adhesive tape supporting body 11 and the external door and window frame profile structure 2 form a first sealing structure and a second sealing structure. The seal portion 12 includes a first seal 121 and a second seal 122, and a first seal structure near the outside is formed by the first seal 121 and a first seal mating member 21 disposed on the out-opening door/window frame section bar structure 2, and a second seal structure near the inside is formed by the second seal 122 and a second seal mating member 22 disposed on the out-opening door/window frame section bar structure 2. Therefore, the two layers of sealing are provided for the outward opening door and window system through the first sealing structure close to the outer side and the second sealing structure close to the inner side which are integrally formed, and the sealing capability is improved.

Example 2:

the first sealing structure is a sealing structure close to the outer side, the second sealing structure is a sealing structure close to the inner side, and the distance from the sealing position of the second sealing structure to the adhesive tape supporting body is smaller than the distance from the sealing position of the first sealing structure to the adhesive tape supporting body.

In some embodiments, the distance from the sealing position of the second sealing structure to the adhesive tape supporting body is smaller than the distance from the sealing position of the first sealing structure to the adhesive tape supporting body, so that a stepped two-layer sealing system is formed, and on one hand, inflow of rainwater can be prevented when power water breaks through the first sealing structure; on the other hand compare in the design of traditional protruding recess structure, this embodiment forms the decline ladder type sealing system that extends to the outside, can help rainwater to discharge and sanitary clean the sweeping.

Example 3:

one of the alternative embodiments of the sealing rubber strip 1 for the out-opening door and the window, the first sealing piece 121 is a first sealing bulge; the first sealing fitting 21 is a first sealing surface; the first sealing protrusion and the first sealing surface form a first sealing structure through first interference fit.

In this embodiment, the first sealing member 121 of the sealing strip 1 for an out-opening door and a window adopts a first sealing protrusion, and the corresponding first sealing mating member 21 configured in the profile structure 2 for an out-opening door and a window frame is a first sealing surface, and the first sealing protrusion is abutted with the first sealing surface to form a first sealing structure so as to seal and block the outside rainwater in a first layer. In a preferred embodiment, the first sealing projection is typically a raised sheet-like strip.

In practical application, the first sealing surface is configured as the surface of the first position of the out-opening door and window frame section structure 2, and since the out-opening door and window sealing adhesive tape 1 is connected to the out-opening door and window sash body section structure 3 and moves along with the out-opening door and window sash body section structure 3, when the window closing action is performed, the out-opening door and window sash body section structure 3 rotates around the rotation axis to approach the out-opening door and window frame section structure 2, and therefore, the first sealing protrusion is configured as the posture of the out-opening door and window sash body section structure 3 being perpendicular or substantially perpendicular to the first sealing surface when the out-opening door and window frame section structure 2 is closed. Moreover, the first sealing protrusion is abutted with the first sealing surface in an interference fit manner, so that the first sealing member 121 is driven by the position of the first sealing member 121 through the outward opening door and window body profile structure 3 and the first sealing member 121 is extruded by the outward opening door and window frame profile structure 2, a firm first sealing structure is realized, and rainwater with a certain kinetic energy or less is prevented from breaking through and flowing in.

The first sealing protrusion is abutted with the first sealing surface to form a first sealing structure so as to seal and block the outer rainwater in a first layer. In a preferred embodiment, the first sealing projection is typically a raised sheet-like strip.

Example 4:

one of the alternative embodiments of the sealing rubber strip 1 for the outward opening door and the outward opening window is characterized in that the first sealing piece is a first sealing bulge; the first sealing fitting is a first sealing surface; the first sealing protrusion is provided with a first sealing surface, a first sealing structure is formed by the first sealing protrusion, and the first sealing protrusion is provided with a first sealing surface.

In this embodiment, the first sealing member 121 of the sealing strip 1 for an out-opening door or window adopts a first sealing protrusion, the corresponding first sealing matching member 21 configured in the profile structure 2 for an out-opening door or window is a first sealing surface, and an isobaric channel formed by the first sealing protrusion pointing to the first sealing surface and the first sealing surface is utilized to realize isobaric setting with an external space.

In practical application, although the first sealing structure adopting interference fit is proposed in the foregoing embodiment, kinetic energy water with a certain kinetic energy can be sealed and blocked in a "blocking" manner. However, in some cases, the door and window system may also face kinetic energy water with larger kinetic energy (for example, when the outdoor side has strong wind pressure, the outdoor atmospheric pressure is greater than the air pressure of the sealing space formed by the first sealing structure and the second sealing structure), at this time, the first sealing structure cannot effectively seal the kinetic energy water in a waterproof manner in a blocking manner, especially consider the sealing strip of the outward opening door and window around the outward opening door and window sash profile structure, the sealing space formed inside the sealing strip is an annular space, if the first sealing structure adopts tight fit interference fit, if the kinetic energy water enters in the upper portion of the annular space, the kinetic energy water can flow to the lower portion of the annular space, and cannot be discharged.

Thus, unlike the previous embodiments, the present embodiment forms an isopiestic channel between the first sealing projection and the first sealing surface by disposing the first sealing structure in such a relationship that the first sealing projection is close to but not in close proximity to the first sealing surface. On the premise of blocking the entry of kinetic energy water to a certain extent, the inner space and the outer space are formed by the isobaric channel, the drainage channel is opened, rainwater entering the sealed space can be discharged, namely, the rainwater entering the annular space is discharged in a 'discharging' mode, and the waterproof effect of the door and window system is improved.

Example 5:

one of the alternative embodiments of the sealing rubber strip 1 for the out-opening door and the window is provided with a blocking protrusion 211 on the first sealing surface; wherein, the blocking protrusion 211 is disposed at the outer side of the position where the first sealing protrusion points to the first sealing surface, and the equal pressure channel is an interlaced channel between the blocking protrusion and the first sealing protrusion.

In this embodiment, since the first sealing protrusion and the first sealing surface are not in close contact with each other and form an equal pressure channel in a close manner, in order to block the equal pressure channel to a certain extent, a blocking protrusion 211 is disposed on the first sealing surface, the blocking protrusion 211 is located outside a position where the first sealing protrusion points to the first sealing surface, and the equal pressure channel is configured as an interlaced channel between the blocking protrusion 211 and the first sealing protrusion.

Therefore, the blocking protrusion 211 arranged on the first sealing surface is matched with the first sealing protrusion, the inner space and the outer space are equal in pressure by utilizing the staggered channels between the blocking protrusion 211 and the first sealing protrusion, rainwater can be further prevented from entering, and the waterproof effect is improved to a certain extent.

Example 6:

one of the alternative embodiments of the sealing rubber strip 1 for the out-opening door and the window is provided with a plurality of guide bosses 212 on the first sealing surface; wherein, the diversion protrusion 212 is disposed at the inner side of the position where the first sealing protrusion points to the first sealing surface, and the annular diversion protrusion surrounding the outward opening door and window sash profile structure forms a diversion drip line.

In this embodiment, a plurality of diversion protrusions 212 are provided on the first sealing surface, and the sealing space formed inside the sealing strip is considered to be an annular space around the outward opening door and window body section structure, so that by providing the annular diversion protrusions formed by the diversion protrusions 212 in the surrounding annular space, the annular diversion protrusions form diversion water drops, when rainwater enters the annular space from the isobaric channel at the upper part of the annular space, due to the tension characteristic of the water, the rainwater can flow along with the inner surface of the annular space, and when the rainwater passes through the plurality of diversion water drops formed, the rainwater can be blocked from flowing further to the inner space, and can flow along with the inner surface of the annular space to the lower part of the annular space, so that the rainwater flow characteristic similar to a rain curtain is formed, and then flows out from the isobaric channel at the lower part of the annular space.

Example 7:

one of the alternative embodiments of the sealing rubber strip 1 for the out-opening door and the window is characterized in that a sealing element connecting piece 23 is arranged between the first sealing element and the second sealing element; wherein the first seal, the second seal and the seal connection 23 form a groove towards the out-opening door and window frame profile structure; wherein, the annular groove around the outward opening door and window sash body profile structure forms a drainage groove.

In this embodiment, a sealing element connector 23 is disposed between the first sealing element and the second sealing element, the first sealing element, the second sealing element and the sealing element connector 23 form a groove facing the frame profile structure of the out-opening door window, and the sealing space formed inside the sealing strip is an annular space considering the out-opening door window sealing strip around the out-opening door window profile structure of the out-opening door window, so that the sealing element connector 23 also forms an annular groove, when the annular groove is located at the upper part of the annular space, the opening of the groove faces upwards, and when the isobaric channel enters the power water, the water is collected in the groove and flows to the lower part of the annular space through the annular groove and flows out through the isobaric channel at the lower part of the annular space, thereby reducing the watertight pressure of the sealing space to the second sealing structure after the power water enters the annular space, and further improving the overall waterproof performance.

Example 8:

one of the alternative embodiments of the sealing strip 1 for the out-opening door and the window, the first sealing surface is provided with: a buffer section; a sealing section; the buffer section is a part, extending outwards, of the sealing position on the first sealing surface; the sealing section is a part, extending inwards, of the sealing position on the first sealing surface; the buffer section, the first sealing protrusion and the outward opening door and window sash body section bar structure 3 form a rainwater buffer space.

In this embodiment, the position where the first sealing protrusion abuts against the first sealing surface is set as the middle section position, instead of the conventional outer side edge position, and the first sealing surface is divided into the buffer section and the sealing section by taking the first sealing protrusion as a boundary. Thus, the first sealing structure is moved inward and is not exposed to the outside, and the problems of natural wind and aging of the sealing rubber strip can be improved.

After the first sealing structure moves inwards, when the window closing action is executed, the outward opening door and window body profile structure 3, the first sealing bulge and the buffer section jointly form a rainwater buffer space, when the outward opening door and window is impacted by the kinetic energy, the kinetic energy of the kinetic energy water is usually dissolved when contacting the window frame, the impact on the sealing rubber strip is obviously reduced, and the problems of bursting the sealing rubber strip and soaking the rubber strip are obviously improved.

Example 9:

in one of the alternative embodiments of the sealing rubber strip 1 for the out-opening door and the out-opening window, the buffer section is provided with a drainage channel.

It should be noted that, the first sealing structure of the conventional outward opening door and window is disposed at the outer side edge of the first sealing surface, however, rainwater generally enters not only between the outward opening door and window sash body profile structure 3 and the outward opening door and window frame profile structure 2, but also flows in or permeates from the upper edge of the outward opening door and window sash body profile structure 3 (for example, when the opening and closing actions of the window are performed), and the existing first sealing structure disposed at the outer side edge of the first sealing surface also blocks the rainwater flowing in or permeated from the upper edge of the outward opening door and window sash body profile structure 3 while blocking the external rainwater from entering, so that the inflow of external rainwater is not completely blocked, but also the rainwater flowing in or permeated from the upper edge cannot be timely removed.

In this embodiment, by moving the first sealing structure inward, on one hand, the rainwater blocking and sealing performance between the outer door and window frame section structure 3 and the outer door and window frame section structure 2 is improved, and on the other hand, the moving first sealing structure can block the rainwater flowing into or penetrating into the upper edge outward, and the rainwater is discharged through the buffer section by passing through the rainwater buffer space formed by the first sealing member 121. That is, by the inward movement of the first seal structure, the inward movement can ensure that the position through which the rainwater flowing in or penetrating from the upper edge flows when flowing through the lower edge is outside the seal space, not inside, thereby directly discharging the rainwater flowing in.

In some embodiments, a drainage channel can be further arranged at the buffer section, so that rainwater between the external door and window frame profile structure 3 and the external door and window frame profile structure 2 and rainwater flowing into the last edge are discharged outwards through the drainage channel. Because the first sealing structure is moved inwards, the drainage channel arranged in the first sealing structure can not damage the sealing performance of the whole door and window.

Example 10:

one of the alternative embodiments of the sealing rubber strip 1 for the out-opening door and the window, the second sealing piece 122 is a second sealing bulge; the second seal mating member 22 is a second sealing surface; the second sealing protrusion and the second sealing surface form a second sealing structure through second interference fit.

In this embodiment, the second sealing member 122 of the sealing adhesive tape 1 for an out-opening door and window adopts a second sealing protrusion, and the corresponding second sealing matching member 22 configured in the profile structure 2 for the frame of the out-opening door and window is a second sealing surface, and the second sealing protrusion is abutted with the second sealing surface to form a second sealing structure, so as to seal and block the rainwater breaking through the first sealing structure in a second layer. In a preferred embodiment, the second sealing protrusion may be any protrusion structure, for example, may be a protruding sheet-shaped adhesive tape, or may be any adhesive tape protruding toward the second sealing surface.

In practical application, the second sealing surface is configured as the surface of the second position of the out-opening door and window frame section structure 2, because the out-opening door and window sealing adhesive tape 1 is connected to the out-opening door and window sash body section structure 3 and moves along with the out-opening door and window sash body section structure 3, when the window closing action is executed, the out-opening door and window sash body section structure 3 rotates around the rotation axis to approach the out-opening door and window frame section structure 2, and the distance from the sealing position of the second sealing structure to the adhesive tape supporting body 11 is smaller than the distance from the sealing position of the first sealing structure to the adhesive tape supporting body 11, therefore, the second sealing protrusion can be configured as the gesture that the out-opening door and window sash body section structure 3 is perpendicular to the first sealing surface or clings to the first sealing surface to form any angle when the out-opening door and window frame section structure 2 is closed. Moreover, the second sealing protrusion is abutted with the second sealing surface in an interference fit manner, so that a relatively firm second sealing structure is realized through the position driving of the outward opening door and window body profile structure 3 on the second sealing piece 122 and the extrusion of the outward opening door and window frame profile structure 2 on the second sealing piece 122, and the distance from the sealing position of the second sealing structure to the adhesive tape supporting main body 11 is smaller than the distance from the sealing position of the first sealing structure to the adhesive tape supporting main body 11, so that rainwater entering after breaking through the first sealing structure is further blocked. And the sealing performance of the system is improved. Meanwhile, on the other hand, compared with a plurality of convex-concave groove sealing structures arranged in the traditional door and window system, the embodiment also solves the problems of water drainage, sanitation, cleanness and the like.

Example 11:

one of the alternative embodiments of the sealing rubber strip 1 for the out-opening door and the window, the interference magnitude of the second interference fit is larger than that of the first interference fit; the first sealing structure and the second sealing structure form a sealing space with internal air pressure being larger than atmospheric air pressure when the window closing action is executed.

In this embodiment, the interference magnitude of the interference fit between the second sealing protrusion and the second sealing surface is greater than the interference magnitude of the interference fit between the first sealing protrusion and the first sealing surface, so that the integrally designed adhesive tape forms an airtight space in the first and second sealing cavities, and when the airtight space closes the window, a certain positive pressure is formed due to the extrusion of the adhesive tape, and when the positive pressure acts on the gap between the first adhesive tape and the window, water can be further prevented from entering through the gap.

Example 12:

one of the alternative embodiments of the sealing rubber strip 1 for the out-opening door and the window, the connecting part 13 comprises: a first connector 131; the first connecting piece 131 is used for being connected with a first connecting matching piece 31 configured by the outward opening door and window sash body profile structure 3, so that the outward opening door and window sealing rubber strip 1 follows the outward opening door and window sash body profile structure 3 to execute the opening and closing actions.

In this embodiment, the connection portion 13 of the sealing adhesive tape 1 for external door and window is configured with a first connection piece 131, where the first connection piece 131 is used to connect with the profile structure 3 for external door and window, so as to drive the sealing adhesive tape 1 for external door and window to execute the opening and closing actions along with the profile structure 3 for external door and window, and further when executing the closing actions, the sealing adhesive tape 1 for external door and window is moved between the profile structure 3 for external door and window and the profile structure 2 for external door and window, and the abutting joint of the sealing adhesive tape 1 for external door and window and the profile structure 2 for external door and window forms a first sealing structure and a second sealing structure; when the opening operation is executed, the sealing rubber strip 1 of the outward opening door and the outward opening window is moved out between the profile structure 3 of the outward opening door and the profile structure 2 of the outward opening door and the window frame. That is, the first connector 131 is used for driving the sealing rubber strip 1 for the out-opening door and the window and plays a certain role in maintaining the position of the sealing rubber strip 1 for the out-opening door and the window.

Example 13:
