Description

Technical Field

[0001] The utility model belongs to the technical field of sealing the gap between window frames and window sashes, and particularly relates to a butterfly-shaped tearable sealing strip. Background Art

[0002] New types of windows such as aluminum alloy windows and plastic steel windows have been widely used. The gaps between the window frames and window sashes of these types of windows need to be sealed with sealing strips. For manufacturers during the production stage, the gaps between the window frames and window sashes of various plastic windows are different, and the existing sealing strips are of fixed height. Generally, manufacturers need to customize multiple sealing strips to adapt to the gap deviations of different types and batches of windows. For users when replacing old and aging sealing strips, it is also very difficult to select a sealing strip suitable for the gap of their own window sashes. Some sealing strips do not have good tension and resilience effects due to their structures, thus reducing the sealing effect and service life. At the same time, the existing sealing strips are fixed by adhesive stickers. This fixing form often causes the sealing strips to be skewed during installation, and when users replace the old sealing strips, it is very difficult to tear them off easily, and there will be a lot of residues that need to be cleaned, which is very troublesome. Summary of the Invention

[0003] The purpose of the utility model is to provide a butterfly-shaped tearable sealing strip, which is formed by stacking and connecting multiple (usually 3 layers) hollow butterfly-shaped structures to form a sealing body with multiple layers and multiple heights. The sealing strips with multiple heights are used to adapt to the sealing of different gaps. Each layer of the sealing body is a cavity, and the structure is similar to a rhombus-shaped disc structure, increasing the elastic tension and strength, greatly enhancing the sealing effect, and being very convenient for installation and removal, with accurate position and not easy to fall off.

[0004] The purpose of the utility model is realized through the following technical solutions:

[0005] The butterfly-shaped tearable sealing strip of the utility model is characterized in that it includes N sealing bodies stacked and lapped and connected to each other, side sealing leaves extending upward outside the connection of one side shoulders of every two adjacent sealing bodies, and a buckle structure arranged at the lower part of the N sealing bodies.

[0006] The two lower feet of the upper sealing body are respectively connected to the upper hypotenuse of the next sealing body to form a sealing body tear point, and the side sealing leaves and the shoulders of each sealing body form side sealing leaf tear points.

[0007] Each sealing body has a symmetrical butterfly-shaped cavity structure, and each side has an inclination.

[0008] The buckle structure includes a fixed connection section and a fixed buckle.

[0009] The fixed buckle is an umbrella-shaped buckle. The fixed connection section is composed of two vertical ribs. The fixed buckle is connected to the lowermost part of the N sealing bodies through the fixed connection section.

[0010] For the N sealing bodies, N is a natural number ranging from 2 to 3.

[0019] The following further describes the specific embodiments of the present utility model with reference to the drawings.

[0020] As Figure 1 、 4As shown in the figure, the butterfly-shaped tearable sealing strip of the present utility model is characterized in that it includes N sealing bodies that are stacked and overlapped with each other, side sealing leaves 8 that extend upward on the outside of the joint of the shoulders on one side of every two adjacent sealing bodies, and a snap structure arranged at the lower part of the N sealing bodies.

[0021] The two lower feet of the previous sealing body are respectively connected to the upper hypotenuse of the next sealing body to form a sealing body tear point 4, and the side sealing leaf 8 and the shoulder of each sealing body form a side sealing leaf tear point 5.

[0022] Each sealing body has a symmetrical butterfly-shaped cavity structure, and each side has an inclination.

[0023] The snap structure includes a fixed connection section 6 and a fixed snap 7.

[0024] The fixed snap 7 is an umbrella-shaped snap. The fixed connection section 6 is composed of two vertical ribs. The fixed snap 7 is connected to the lowermost part of the N sealing bodies through the fixed connection section 6.

[0025] For the N sealing bodies, N is a natural number with a value of 2-3.

[0026] Such as Figure 1 , it is a butterfly-shaped tearable sealing strip for a window formed by stacking and connecting three layers of sealing bodies. The sealing body 1, the sealing body 2, and the sealing body 3 are stacked and overlapped with each other. Each sealing body has a symmetrical butterfly-shaped structure. The two lower feet of the butterfly-shaped structure of the previous sealing body are respectively connected to the upper hypotenuse of the butterfly shape of the next sealing body to form a sealing body tear point 4. The connection width of the sealing body tear point 4 can not only ensure the connection strength but also be manually torn and separated; the sealing body has a butterfly-shaped structure, and each side has an inclination, which can not only make it have a certain elastic stiffness while saving materials, but also naturally and symmetrically contract during the pressing process to prevent stacking and deformation, which affects the service life; the upper and lower hypotenuses on one side of the butterfly-shaped sealing body 1 are respectively connected to a side sealing leaf 8 that extends upward, and the side sealing leaf 8 is respectively connected to the sealing body 2 and the sealing body 3 through the side sealing leaf tear point 5. The side sealing leaf tear point 5, like the sealing body tear point 4, can not only ensure the connection but also be manually torn off. In this way, according to the required sealing gap, a butterfly-shaped sealing strip with three heights and with side sealing leaves 8 can be formed by manually tearing off ( Figure 1 , Figure 2 , Figure 3 ).

[0027] Such as Figure 4, the lower part of the sealing strip is a buckle structure for installation and fixation on the window sash. It consists of a fixed connection section 6 and a fixed buckle 7. The umbrella-shaped fixed buckle 7 is connected to the main body of the sealing strip through the connection section 6. During installation, the fixed buckle 7 is pressed into the corresponding slot 9 of the window sash. The umbrella-shaped fixed buckle 7 firmly clamps and fixes the sealing strip on the window sash 11. Since the slot 9 is pre-made, this fixing method ensures the installation straightness of the sealing strip and is also convenient for installation and replacement; the sealing of this butterfly-shaped sealing strip relies on the side sealing leaf 8 extending outward and pressing against the window frame 10 when closing the window to form the first seal. After the window sash 11 is tightly closed, the upper part of the butterfly-shaped seal body presses tightly against the window frame 10 to form the second seal, greatly increasing the sealing effect.

[0028] This tearable sealing strip is made of new elastic materials such as TPE, TPR, or ethylene propylene diene monomer (EPDM). It has good strength, ductility, heat resistance, and corrosion resistance, ensuring the elastic tension and service durability required for the tearable sealing strip in the door closing and pressing and fixing states.

[0029] The butterfly-shaped tearable sealing strip of the present utility model is formed by stacking and connecting multiple (usually 3 layers) hollow butterfly-shaped structures to form a sealing body with multiple layers and various heights. There are fine connections between each layer of the sealing body, and it can be manually torn at the tear point to form sealing strips with various heights to adapt to the sealing of different gaps. Each layer of the sealing body is a cavity, and the structure is similar to a rhombus-shaped disc structure, increasing the elastic tension and strength. An elastic side sealing leaf 8 is provided on one side of the sealing strip. When closing the window, the side leaf closely adheres to the window frame 10 to form the first seal and forms a double-seal effect with each layer of the butterfly-shaped seal body, greatly increasing the sealing effect. The lower part of this tearable sealing strip adopts a buckle structure for installation and fixation. During installation, it is snapped into the slot of the window sash, and it is very convenient to install and remove, with accurate positioning and not easy to fall off.
