Description

Technical Field

[0001] The utility model relates to the technical field of heat-insulating rubber strips, in particular to a heat-insulating rubber strip for a thermally insulated aluminum window. Background Art

[0002] Broken bridge aluminum refers to an aluminum profile that is broken in the middle and then connected together through a hard plastic connection. Since the thermal conductivity of plastic is slower than that of metal, the thermal insulation performance of the window made of it is better, which effectively reduces the heat conducted through the window and improves the user's comfort indoors. In order to reduce the transfer of heat in the aluminum profile, a thermal insulation strip is usually installed in the aluminum profile, so that the thermal insulation strip serves as a "broken bridge" on the heat transfer path in the aluminum profile. During the connection process between the thermal insulation strip and the aluminum profile, it was found that the connection strength between the thermal insulation strip and the aluminum profile is low. If the thermal insulation strip is separated from the original installation location due to collision during normal use of the window, it will affect the overall thermal conductivity of the broken bridge aluminum window.

[0006] By adopting the above technical solution, a positioning groove is formed between the positioning block composed of the upper positioning section and the lower positioning section and the side wall of the rubber strip body, and a mounting block that cooperates with the positioning groove is integrally formed on the aluminum profile, so that the rubber strip body and the aluminum profile can be fixed by snapping. Compared with direct embedding, the connection strength between the thermal insulation rubber strip and the aluminum profile is effectively improved.

[0007] Preferably, fixing plates are embedded on both sides of the rubber strip body, and positioning elastic members are provided on the fixing plates. The positioning elastic members are used to drive the positioning block to bend toward the positioning groove.

[0008] By adopting the above technical solution and setting a positioning elastic member connected to the fixing plate, the upper positioning section and the lower positioning section are bent toward the positioning groove. During the process of installing the rubber strip body to the aluminum profile, the rubber strip body is not easily deformed, thereby improving the stability of the thermal insulation strip itself and increasing the pressure between the positioning spring sheet and the aluminum profile, thereby increasing the connection strength between the thermal insulation strip and the aluminum profile.

[0009] Preferably, a friction-enhancing strip that fits with the aluminum profile is further provided on the side wall of the rubber strip body.

[0010] By adopting the above technical solution and setting the friction increasing strip, the friction between the rubber strip body and the aluminum profile is increased, thereby further increasing the connection strength between the thermal insulation rubber strip and the aluminum profile, making it difficult for the thermal insulation rubber strip to slip relative to the aluminum profile.

[0011] Preferably, a cavity is formed through the rubber strip body, the cavity is formed along the length direction of the rubber strip body, a support block is provided on the rubber strip body, the support block is located in the cavity and connected to the inner wall of the cavity, and the support block is arranged along the length direction of the rubber strip body.

[0012] By adopting the above technical solution and setting the support block, the rubber strip body is not easily deformed by the cavity, which effectively controls the energy loss caused by the convection effect in the rubber strip body cavity, and also effectively controls the energy loss caused by radiation on the surface of the aluminum profile.

[0013] Preferably, the rubber strip body comprises a plurality of rubber strip sections and a connecting section, two adjacent rubber strip sections are connected via the connecting section, and the connecting section is embedded in the cavity and fits against the inner wall of the cavity.

[0014] By adopting the above technical solution, due to the size of the window, it may be necessary to connect the two adjacent sections of the rubber strip through a connecting part, thereby extending the length of the rubber strip body and facilitating the adjustment of the size of the rubber strip body; after the connecting part is respectively embedded in the cavity of the two rubber strip parts, the two adjacent rubber strip parts are fixed, which facilitates the connection between the two adjacent rubber strip parts.

Due to the interference fit between the fixing column and the fixing groove, the reliability of the connection between the two adjacent sections of the rubber strip is further improved. The operation is simple and convenient for connecting the two sections of the rubber strip. The interlocking arc surface can provide a guide for the fixing column to be embedded in the fixing groove, making it convenient for the fixing column to be embedded in the fixing groove.

[0017] Preferably, the fixing column is made of hard material.

[0018] By adopting the above technical solution, since the fixing column is made of hard material, the fixing column itself has a certain strength, which further facilitates the fixing column to be embedded in the fixing groove.

[0019] Preferably, the support block is divided into an upper support portion and a lower support portion, the upper support portion and the lower support portion are respectively arranged at two ends of the rubber strip body in the thickness direction, and the upper support portion and the lower support portion are staggered.

[0020] By adopting the above technical solution, since the upper support part and the lower support part are staggered, with the cooperation of the upper support part and the lower support part, the energy loss caused by the convection effect in the cavity of the rubber strip body is further controlled.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. A positioning groove is formed between the positioning block composed of the upper positioning section and the lower positioning section and the side wall of the rubber strip body. A mounting block that matches the positioning groove is integrally formed on the aluminum profile, so that the rubber strip body and the aluminum profile can be fixed by snapping. Compared with direct embedding, the connection strength between the thermal insulation rubber strip and the aluminum profile is effectively improved;

[0023] 2. By setting a positioning elastic member connected to the fixing plate, the upper positioning section and the lower positioning section are bent toward the positioning groove. During the installation of the rubber strip body to the aluminum profile, the rubber strip body is not easily deformed, thereby improving the stability of the thermal insulation strip itself and increasing the pressure between the positioning spring sheet and the aluminum profile, thereby increasing the connection strength between the thermal insulation strip and the aluminum profile.

[0027] The following is combined with Figure 1-2The utility model is described in further detail.

[0028] The present application embodiment discloses a thermal insulation strip for a thermally insulated aluminum window. Figure 1 and Figure 2 , including a rubber strip body 1, the rubber strip body 1 is embedded in an aluminum profile, the aluminum profile includes an embedding cavity for embedding and installing the rubber strip body 1, and a mounting block is fixed on the inner wall of the embedding cavity, and the mounting block is integrally formed with the aluminum profile. Both sides of the rubber strip body 1 are integrally formed with positioning blocks 2, which are arranged along the length direction of the rubber strip body 1. The positioning blocks 2 include an upper positioning section 21 and a lower positioning section 22, which are relatively arranged at the two ends of the rubber strip body 1 in the thickness direction. The upper positioning section 21 and the lower positioning section 22 are both arranged in an arc shape, and the ends of the upper positioning section 21 and the lower positioning section 22 away from the rubber strip body 1 are arranged toward the rubber strip body 1. A positioning groove 23 cooperating with the mounting block is formed between the positioning block 2 composed of the upper positioning section 21 and the lower positioning section 22 and the side wall of the rubber strip body 1. After the rubber strip body 1 is embedded in the fitting cavity, the positioning block 2 is fitted with the mounting block as a whole. The rubber strip body 1 is fixed to the aluminum profile by a snap-fitting method. Compared with direct fitting, the connection strength between the rubber strip body 1 and the aluminum profile is effectively improved.

[0029] Reference Figure 1 and Figure 2 , fixing sheets 3 are also embedded on both sides of the rubber strip body 1, and a positioning elastic member is provided on the side of the fixing sheet 3 facing the positioning block 2, and the positioning elastic member is used to drive the positioning block 2 to slide toward the positioning groove 23. In the embodiment of the present application, the positioning elastic member is a positioning spring sheet 31 with elasticity, and positioning spring sheets 31 are provided at both ends of the fixing sheet 3 in the width direction. The positioning spring sheets 31 are integrally formed with the fixing sheet 3, and the positioning spring sheets 31 at both ends of the fixing sheet 3 are respectively arranged corresponding to the upper positioning segment 21 and the lower positioning segment 22, and the positioning spring sheet 31 close to the upper positioning segment 21 extends into the upper positioning segment 21, and the positioning spring sheet 31 close to the lower positioning segment 22 extends into the lower positioning segment 22. The fixing sheet 3 and the positioning spring sheet 31 are pre-embedded in the rubber strip body 1 during the manufacturing process of the rubber strip body 1.

[0030] By setting the positioning spring piece 31, the upper positioning section 21 and the lower positioning section 22 are bent toward the positioning groove 23. During the process of installing the rubber strip body 1 to the aluminum profile, the rubber strip body 1 is not easy to deform, which improves the stability of the rubber strip body 1 itself and can increase the pressure between the positioning spring piece 31 and the aluminum profile, thereby increasing the connection strength between the rubber strip body 1 and the aluminum profile.

[0031] Reference Figure 1 and Figure 2A friction strip 4 is also embedded on the side wall of the rubber strip body 1. The friction strip 4 is arranged along the length direction of the rubber strip body 1. The friction strip 4 can be fixed to the rubber strip body 1 by gluing. The friction strip 4 is located between the upper positioning section 21 and the lower positioning section 22. After the rubber strip body 1 is fixed to the aluminum profile, the end of the friction strip 4 facing away from the rubber strip body 1 fits with the aluminum profile, which increases the friction between the rubber strip body 1 and the aluminum profile, thereby further increasing the connection strength between the rubber strip body 1 and the aluminum profile, making it difficult for the rubber strip body 1 to slip relative to the aluminum profile.

[0032] Reference Figure 1 and Figure 2 A cavity 11 is formed through the rubber strip body 1, and the cavity 11 is formed along the length direction of the rubber strip body 1. A support block 12 is integrally formed on the rubber strip body 1, and the support block 12 is located in the cavity 11. The support block 12 is arranged along the length direction of the rubber strip body 1. Through the arrangement of the support block 12, the rubber strip body 1 is not easily deformed by the cavity 11, and the energy loss caused by the convection effect in the cavity 11 of the rubber strip body 1 is effectively controlled, and the energy loss caused by the radiation on the surface of the aluminum profile is also effectively controlled.

[0033] Reference Figure 1 and Figure 2 The support block 12 is divided into an upper support portion 121 and a lower support portion 122. The upper support portion 121 and the lower support portion 122 are respectively located at the two ends of the thickness direction of the rubber strip body 1. The upper support portion 121 and the lower support portion 122 are staggered in the vertical direction. With the cooperation of the upper support portion 121 and the lower support portion 122, the energy loss caused by the convection effect in the cavity 11 of the rubber strip body 1 is further controlled.

[0034] Reference Figure 1 and Figure 2 The rubber strip body 1 includes multiple rubber strip parts 13 and a connecting part 14. During the use of the rubber strip body 1, due to the size of the window, it may be necessary to connect two adjacent rubber strip parts 13 through the connecting part 14, thereby extending the length of the rubber strip body 1. The connecting part 14 is made of the same material as the rubber strip body 1. The two ends of the connecting part 14 are respectively embedded in the cavity 11 of the two adjacent rubber strip parts 13. Both ends of the connecting part 14 are provided with a snap-in groove 141 for the upper support part 121 and the lower support part 122 to engage with each other, so that the connecting part 14 embedded in the cavity 11 fits with the inner wall of the cavity 11, which is convenient for connecting the two adjacent rubber strip bodies 1.

[0035] Reference Figure 2, both ends of the connection part 14 are fixed with fixing columns 142, and the fixing columns 142 are located in the clamping grooves 141. The fixing columns 142 are made of hard materials. In the embodiment of the present application, the fixing columns 142 are made of hard plastic materials. The fixing columns 142 are fixed to the connection part 14 by gluing or pre-embedding. The upper support part 121 and the lower support part 122 are respectively provided with fixing grooves 123 for the fixing columns 142 to be embedded. The fixing grooves 123 are arranged along the length direction of the rubber strip part 13. After the connection part 14 is embedded in the cavity 11, the fixing columns 142 can be embedded in the corresponding fixing grooves 123. Since the fixing columns 142 are made of hard plastic materials, the fixing columns 142 themselves have a certain strength, which facilitates the sliding of the fixing columns 142 into the fixing grooves 123.

[0036] Reference Figure 2 , so that the fixing column 142 and the fixing groove 123 have an interference fit, and the fixing column 142 has an integrally formed embedded arc surface 143 on the end away from the support block 12, and the embedded arc surface 143 provides guidance for the fixing column 142 to be embedded in the fixing groove 123. Since the fixing column 142 and the fixing groove 123 have an interference fit, the reliability of connecting the two adjacent sections of the rubber strip 13 through the connecting part 14 is further improved, and the operation is simple, which facilitates the connection between the two sections of the rubber strip 13.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
