Description

Technical Field

[0001] The utility model relates to the technical field of door and window profiles, in particular to a door and window profile with a heat preservation structure. Background Technique

[0002] Doors and windows play roles such as sunshading, anti-theft, decoration, energy conservation and emission reduction, and sound insulation in buildings. The heat preservation performance and sound insulation effect of doors and windows have always been important criteria for measuring the grade of doors and windows in the door and window industry. The heat preservation structure of door and window profiles mainly includes the use of a heat preservation cavity structure and heat insulation strips.

[0003] A plastic profile door and window profile with a heat preservation structure, with the authorized announcement number of CN 217233229 U in China, combines an outer heat preservation board and an inner heat preservation board to achieve the effect of heat preservation. And in subsequent use, when only the outer heat preservation board on the outside is damaged, the inner heat preservation board is removed and replaced, and the inner heat preservation board is retained, achieving the saving of costs and resources, and making good improvement to the current heat preservation plastic profiles.

[0004] However, there are still certain deficiencies in the use of this patent. Most of the existing door and window profiles use a single-cavity structure for sound insulation and heat preservation, with poor sound insulation and heat preservation effects. And if the cavity reaches a certain volume, the air in the cavity will also generate convection, resulting in energy loss, and the door and window structure will not be able to maintain heat. In addition, the waterproof and sealing performance of most existing doors and windows is poor. When it rains, rainwater easily enters the heat preservation cavity, making the internal heat preservation material wet, thereby reducing the heat preservation effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide a door and window profile with a heat preservation structure to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A door and window profile with a heat preservation structure includes a first profile structure and a second profile structure. The first profile structure includes a first profile body. Inside the first profile body, a first heat preservation material is fixedly connected through a first sealing gasket and a second sealing gasket. The bottom of the first sealing gasket is set as a first connection part, and the bottom of the first profile body is provided with a second connection part. The side of the first profile body is fixedly connected with an anti-collision rubber strip. A buffer material is arranged in the top cavity of the first profile body. The top of the buffer material is elastically connected with a glass mounting seat. The glass mounting seat is fixedly connected with the first profile body through a sealing rubber strip. Three glass bodies are fixedly connected to the top of the glass mounting seat. The three glass bodies are separated by spacer bars.

[0008] As a preferred embodiment of the present utility model, the second profile structure includes a second profile body, inside which a third gasket and a fourth gasket are fixedly connected, and a support skeleton is arranged inside the second profile body.

[0009] As a preferred embodiment of the present utility model, a second thermal insulation material is elastically connected to the top of the third gasket, the second thermal insulation material is embedded with the support skeleton, and the top of the second thermal insulation material is elastically connected to the fourth gasket.

[0010] As a preferred embodiment of the present utility model, a sealing block is arranged on the top of the fourth gasket, the side surface of the sealing block is a third connection part, and the third connection part is fitted and connected with the first connection part.

[0011] As a preferred embodiment of the present utility model, a sealing convex block is arranged on the side surface of the second profile body, the sealing convex block is clamped with an anti-collision rubber strip, a fourth connection part is arranged on the side surface of the second profile body, and the fourth connection part is fitted and connected with the second connection part.

The multi-chamber structure effectively divides the space between the inner profile and the outer profile, avoiding the air convection phenomenon in the cavity, thereby increasing the effects of the door and window profiles in terms of heat preservation, steam resistance and sound insulation. Moreover, by filling a low thermal conductivity thermal insulation material in the profile cavity, the air convection in the cavity part of the heat insulation strip is reduced, thereby improving the heat preservation performance of the doors and windows.

[0017] 2. In the present utility model, by providing the first connection part, the third connection part, the second connection part and the fourth connection part, the sealing performance of the doors and windows is improved.

Moreover, the material of the connection parts is a nylon heat insulation strip with a relatively low heat transfer rate, effectively solving the problem of heat transfer of the door and window profiles.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment, please refer to Figures 1-4 , the present utility model provides a technical solution:

[0025] A door and window profile with a heat preservation structure, comprising a first profile structure 1 and a second profile structure 2. The first profile structure 1 includes a first profile body 101. A collision-proof rubber strip 105 is fixedly connected to the side of the first profile body 101. A buffer material 3 is arranged in the top cavity of the first profile body 101. The top of the buffer material 3 is elastically connected to a glass mounting seat 5. The glass mounting seat 5 is fixedly connected to the first profile body 101 through a sealing rubber strip 4. Three glass bodies 6 are fixedly connected to the top of the glass mounting seat 5. The three glass bodies 6 are separated by a spacer 7. The second profile structure 2 includes a second profile body 201. A third sealing gasket 202 and a fourth sealing gasket 205 are fixedly connected inside the second profile body 201. A sealing block 206 is arranged on the top of the fourth sealing gasket 205. A sealing convex block 209 is arranged on the side of the second profile body 201. The sealing convex block 209 is clamped with the collision-proof rubber strip 105. The materials of the first heat preservation material 107 and the second heat preservation material 203 are set as polyurethane foam. The materials of the first sealing gasket 102, the second sealing gasket 106, the third sealing gasket 202 and the fourth sealing gasket 205 are set as soft rubber.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, a first heat preservation material 107 is fixedly connected inside the first profile body 101 through a first sealing gasket 102 and a second sealing gasket 106. A support skeleton 204 is arranged inside the second profile body 201. The top of the third sealing gasket 202 is elastically connected to a second heat preservation material 203. The second heat preservation material 203 is embedded with the support skeleton 204. The top of the second heat preservation material 203 and the fourth sealing gasket 205 are elastically connected. The first profile body 101 is a multi-cavity structure. The material of the first profile body 101 is glass fiber reinforced polyurethane. The second profile body 201 is a multi-cavity structure. The material of the second profile body 201 is glass fiber reinforced polyurethane.

[0027] Wherein, by setting the first profile body 101 and the second profile body 201 as multi-cavity structures, and filling the first heat preservation material 107 and the second heat preservation material 203 inside the first profile body 101 and the second profile body 201, the heat preservation performance of the doors and windows is improved. The multi-cavity structure effectively divides the space between the inner profile and the outer profile, avoiding the convection phenomenon of the air in the cavity, thereby increasing the effects of the door and window profile in three aspects of heat preservation, steam resistance and sound insulation. Moreover, by filling a low thermal conductivity heat preservation material in the profile cavity, the air convection in the cavity part of the heat insulation strip is reduced, thereby improving the heat preservation performance of the doors and windows.

[0029] Among them, by setting the first connection part 103 and the third connection part 207, as well as the second connection part 104 and the fourth connection part 208, the sealing performance of the doors and windows is improved. When the doors and windows are in the closed state, between the first connection part 103 and the third connection part 207, as well as between the second connection part 104 and the fourth connection part 208, there is a sealing structure with concave and convex mutual fitting, which increases the contact area between the connection parts, thus making the sealing performance better. Moreover, the material of the connection part is a nylon heat insulation strip with a relatively low heat transfer rate, effectively solving the heat transfer problem of the door and window profiles.

By setting the first connection part 103 and the third connection part 207, as well as the second connection part 104 and the fourth connection part 208, the sealing performance of the doors and windows is improved. Moreover, between the connection parts, there is a sealing structure with concave and convex mutual fitting, which increases the contact area between the connection parts, thus making the sealing performance better. Moreover, the material of the connection part is a nylon heat insulation strip with a relatively low heat transfer rate, effectively solving the heat transfer problem of the door and window profiles.
