Description

Technical Field

[0001] This utility model relates to the field of profile connection technology, and in particular to a profile connection sealing structure. Background Technology

[0002] In modern construction and industrial manufacturing, aluminum alloy profiles, PVC profiles, and composite material profiles are widely used in doors and windows, curtain walls, display racks, furniture, and other fields. When these profiles are assembled into a frame structure, interconnection is inevitable. Traditional profile connection methods, such as using angle brackets or direct screw fastening, while achieving structural fixation, often create gaps at the joints. These gaps not only compromise the overall airtightness of the structure, reducing the heat insulation, sound insulation, waterproofing, and dustproofing performance of doors and windows, but also easily accumulate moisture and dirt, which over time can lead to corrosion and mold growth at the profile joints, shortening the lifespan of the entire structure.

[0003] To address sealing issues, current technologies typically involve applying sealant to the external gaps at the profile connections after installation. However, this application process requires skilled workers, as the amount of sealant is difficult to control, leading to problems such as excess sealant, sealant breaks, and uneven sealing, affecting both aesthetics and sealing effectiveness. Furthermore, the sealant is prone to aging and cracking, requiring regular maintenance and replacement, increasing long-term operating costs. Additionally, some structures use independent sealing strips, but these often only cover a single gap, resulting in poor sealing for multiple joints and making installation and positioning difficult.

[0004] Therefore, there is an urgent need to design a profile connection sealing structure to solve the problems of poor sealing performance, easy aging, and inconvenient installation at the profile connection in the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a profile connection sealing structure to solve the problems of poor sealing performance, easy aging, and inconvenient installation at the profile connection in the prior art.

[0006] The technical solution of this utility model is: a profile connection sealing structure, comprising: a first profile and a second profile, and a connecting profile connecting the first profile and the second profile; It also includes a seal that spans and simultaneously covers the joint gap between the first profile and the connecting profile, as well as the joint gap between the second profile and the connecting profile.

[0007] Preferably, the connecting profile has connecting portions at both ends for connecting the first profile and the second profile, and the first profile and the second profile are respectively provided with a first connecting structure and a second connecting structure corresponding to the connecting portions.

[0008] Preferably, the first profile and the connecting profile are provided with a first limiting part and a second limiting part in a longitudinal direction from the outside to the inside.

[0009] Preferably, a third limiting part and a fourth limiting part are provided longitudinally from the outside to the inside on the side where the second profile is connected to the connecting profile. During assembly, the side closer to the sealing element is the outside. The third limiting part and the fourth limiting part are the second connecting structure, and a second cavity adapted to the connecting part is formed between them.

[0010] Preferably, the sealing element is fixedly connected to the connecting profile and / or the first profile and / or the second profile through a snap-fit ​​structure.

[0011] Preferably, the snap-fit ​​structure is a snap hook fixed on the connecting profile and / or the first profile and / or the second profile, and a snap-fit ​​groove formed on the sealing element, wherein the snap hook and the snap-fit ​​groove are adapted to each other and are snap-fitted together.

[0012] Preferably, the first limiting part is provided with a first locking protrusion, the third limiting part is provided with a second locking protrusion, and the sealing member is provided with two locking grooves on the side near the first profile and the second profile, which are adapted to the first locking protrusion and the second locking protrusion.

[0018] The present invention will be further described in detail below with reference to specific embodiments.

[0019] Example 1:

[0020] like Figure 1 As shown, a profile connection sealing structure includes a first profile 1, a second profile 2, a connecting profile 3, and a sealing element 4.

[0021] like Figure 1 and Figure 8 As shown, the connecting profile 3 is located between the first profile 1 and the second profile 2, and is used to connect the first profile 1 and the second profile 2. The sealing member 4 spans and simultaneously covers the connection gap between the first profile 1 and the connecting profile 3, as well as the connection gap between the second profile 2 and the connecting profile 3. The sealing member 4 is constructed to produce elastic deformation and is made of a flexible material with good elasticity and weather resistance, such as rubber or foam.

[0022] Depending on the actual application scenario and the requirements for sealing performance, the sealing element 4 can be arranged on one or both sides where the first profile 1, the second profile 2 and the connecting profile 3 are connected.

[0023] like Figure 2 and Figure 3 As shown, the connecting profile 3 is provided with connecting parts 31 at both ends for connecting the first profile 1 and the second profile 2. The first profile 1 and the second profile 2 are respectively provided with a first connecting structure and a second connecting structure corresponding to the connecting parts 31.

[0024] The first profile 1 and the connecting profile 3 are connected longitudinally from the outside to the inside, with a first limiting part 11 and a second limiting part 12 arranged sequentially. During assembly, the side closer to the sealing element 4 is the outer side. The first limiting part 11 and the second limiting part 12 are the first connecting structure, and a first cavity adapted to the connecting part 31 is formed between them.

[0025] The second profile 2 and the connecting profile 3 are provided with a third limiting part 21 and a fourth limiting part 22 in a longitudinal direction from the outside to the inside. During assembly, the side closer to the sealing element 4 is the outside. The third limiting part 21 and the fourth limiting part 22 are the second connecting structures, and a second cavity that is adapted to the connecting part 31 is formed between them.

[0026] During assembly, the first profile 1 and the second profile 2 are first aligned and arranged in a preset orientation, and then the connecting profile 3 is assembled and connected along the axial direction. Specifically, the two connecting parts 31 at both ends of the connecting profile 3 are pushed into the first cavity of the first profile 1 and the second cavity of the second profile 2, respectively, until the end face of the connecting part 31 abuts against the bottom of the cavity, so as to achieve a stable positioning of the three.

[0027] like Figure 1 , Figure 6 and Figure 7 As shown, the sealing element 4 is fixedly connected to the connecting profile 3 and / or the first profile 1 and / or the second profile 2 through a snap-fit ​​structure.

[0028] The snap-fit ​​structure consists of a snap hook 5 fixed on the connecting profile 3 and / or the first profile 1 and / or the second profile 2, and a snap-fit ​​groove 41 opened on the sealing element 4. The snap hook 5 and the snap-fit ​​groove 41 are compatible and snap-fit ​​together.

[0029] It is worth noting that the arrangement of the hooks 5 is diverse, including but not limited to the forms shown in the figure. Considering both manufacturing costs and the stability of the seal 4 connection, preferably, two sets of hooks 5 are used, and the hooks of the two sets of hooks 5 can be arranged opposite each other or back to back, so as to provide a balanced locking force on the seal 4 from different directions and prevent it from loosening.

[0030] Working principle: During assembly, first assemble the first profile 1, the second profile 2, and the connecting profile 3. Then, place the sealing element 4 in the appropriate assembly position and apply force so that the hook 5 engages in the corresponding locking groove 41. Due to the elasticity of the sealing element 4 material, the hook 5 can smoothly engage and lock in the locking groove 41, thereby fixing the sealing element 4 to the profile. The elasticity of the sealing element 4 allows it to fit tightly against the surface of the profile, thereby sealing the gap at the joint between the first profile 1, the second profile 2, and the connecting profile 3.

[0031] Example 2:

[0032] like Figures 4 to 5 As shown, this embodiment has the same basic structure as Embodiment 1, the difference being the different snap-fit ​​structure between the seal 4 and the profile.

[0033] In this embodiment, the snap-fit ​​structure is provided with a first snap-fit ​​protrusion 111 on the first limiting part 11 and a second snap-fit ​​protrusion 211 on the third limiting part 21. The sealing member 4 is provided with two snap-fit ​​grooves 41 on the side near the first profile 1 and the second profile 2, which are adapted to the first snap-fit ​​protrusion 111 and the second snap-fit ​​protrusion 211. The first snap-fit ​​protrusion 111 and the second snap-fit ​​protrusion 211 are respectively snapped into the two snap-fit ​​grooves 41.

[0034] Working principle: During assembly, the first profile 1, the second profile 2, and the connecting profile 3 are first assembled. Then, the sealing element 4 is placed in a suitable assembly position and force is applied, causing the first locking protrusion 111 and the second locking protrusion 211 to respectively engage in the corresponding locking grooves 41. Due to the elasticity of the sealing element 4 material, the first locking protrusion 111 and the second locking protrusion 211 can smoothly engage and lock in the locking grooves 41, thereby fixing the sealing element 4 to the profile. The elasticity of the sealing element 4 allows it to fit tightly against the surface of the profile, thereby sealing the gaps at the joints between the first profile 1, the second profile 2, and the connecting profile 3.
