Description

Sealing tops for easy installation

technical field

The invention relates to the field of seals, in particular to a sealing top which is convenient for embedding.

Background technique

Door and window sealing tops are made of high-quality random polypropylene as raw materials, and are synthesized with siliconized polypropylene fibers and polypropylene films. The product design is unique and has passed the test of the National Building Materials Testing Center. and other sealed high-end products.

In the prior art, the sealing top strip is installed in the slot of the door and window by inserting. Specifically, the slot on the door and window is a T-shaped structure, the bottom plate of the sealing top is matched in the slot, and the width of the bottom plate of the sealing top is larger than the width of the slot of the slot to form a positioning. The sealing wire of the sealing top extends to the outside of the card groove through the notch of the card groove, so as to achieve the sealing effect. During the process of embedding the sealing top strip into the card groove, it is necessary to insert the two edges of the sealing top strip, that is, the parts of the bottom plate corresponding to both sides of the sealing wire, into the card groove by extrusion deformation. Because the length of the edge that needs to be deformed and pressed into the slot on the bottom plate is large, that is, a complete edge extending along the length of the bottom plate, the pressure required for the edge of the bottom plate to deform is relatively large, and it is also easy to cause the edge of the bottom plate to bend during the bending process. The problem of being broken in the middle, so there is room for improvement.

SUMMARY OF THE INVENTION

In view of the deficiencies of the prior art, the present invention provides a sealing top strip which is easy to be embedded, which can not only facilitate the bottom plate of the sealing top to be embedded in the slot of the door and window, but also reduce the possibility of the sealing top being damaged during the embedding process. sex.

For achieving the above object, the present invention provides the following technical solutions:

A sealing top strip which is easy to be embedded, is characterized in that: it comprises a bottom plate and a sealing wire extending along the length direction of the bottom plate and compounded on the bottom plate, and the width of the bottom plate is larger than that of the sealing wire, so as to reserve clamping edges on both sides;

The clamping edge is provided with a plurality of notches arranged along the length direction of the clamping edge, and a clamping protrusion matched with the clamping groove is formed between every two adjacent notches.

Preferably, the snap-fit protrusion is an isosceles trapezoid structure.

Preferably, the notches on the two clamping edges are arranged in a staggered arrangement.

Preferably, the length of the notch is less than the length of the snap-fit protrusion.

Preferably, a sponge layer is compounded on the side of the bottom plate facing away from the sealing wire.

The advantages of the present invention are: the setting of the notch on the clamping edge can form the intermittently arranged clamping protrusions on the clamping edge, and in the process of being inserted into the clamping groove, only the intermittently arranged clamping protrusions need to be inserted one by one. It can be inserted into the card slot; the one-by-one snap-in of the snap-on protrusions requires less force than the continuous snap-in of the traditional unnotched continuous snap-on edges, and at the same time will not cause damage, so it is significantly Improves the convenience of operator carding.

FIG. 2 is a schematic diagram of the fitting of the sealing top strip for easy installation in the card groove provided by the present embodiment.

Detailed ways

With reference to Fig. 1 to Fig. 2, the sealing top strip for easy embedding of the present invention will be further described.

A sealing top strip which is easy to be embedded, is characterized in that it comprises a bottom plate 2 and a sealing wire 1 extending along the length direction of the bottom plate 2 and compounded on the bottom plate 2, and the width of the bottom plate 2 is greater than the width of the sealing wire 1, so that the width of the bottom plate 2 is greater than that of the sealing wire 1. A snap edge 21 is reserved on the side. The clamping edge 21 is provided with a plurality of notches 211 arranged along the length direction of the clamping edge 21 , and a clamping protrusion 212 for clamping with the clamping slot 3 is formed between each two adjacent notches 211 .

In the process of being snapped into the card slot 3, it is only necessary to snap the intermittently arranged snap-on projections 212 into the card slot 3 one by one; The continuous clamping of the clamping edge in the continuous state requires less force, and at the same time does not cause damage or has a relatively low possibility of causing damage, thus significantly improving the convenience of the operator's clamping. Specifically, during the clipping process of the clipping edge without the opening 211, the clipping edge cannot be clipped into the clip slot 3 at one time due to the long extension length of the clipping edge, and only the clipping part can be inserted into the clip slot 3. It is gradually inserted into the card slot 3 along its length direction. Under this clamping structure, part of the clamping edge 21 is located in the clamping slot 3, and part is outside the clamping slot 3, so that the notch 31 of the clamping slot 3 always presses the local position of the clamping edge, which is easy to cause The notch 31 of the card slot 3 will damage the clamping edge that is at the notch 31 and the clamping edge that does not enter the card slot 3 but will enter the card slot 3; and in the present invention, one side of the clamping edge is first 21 is inserted into the card slot 3, and the snap-on protrusions 212 on the other snap-on edge 21 are snapped into the card slot 3 one by one. In this process, because the length of the snap-on protrusion 212 is short, it can be snapped into the snap-in slot 3 at one time, which reduces the deformation of the snap-on protrusion 212 at the slot 31 of the snap-on slot 3 by being squeezed by the slot of the snap-fit slot 3 . Therefore, this embodiment is not easy to be damaged during the clipping process; at the same time, because the length of the clipping protrusion is short, the force required for clipping into the clip slot for deformation is small, which is convenient for operators to operate.

The clamping protrusion 212 is an isosceles trapezoid structure. The trapezoidal structure has the characteristics of stable structure and high strength, which can not only avoid the problem of breakage of the clamping protrusion 212 during deformation and enter the clamping slot 3 , but also improve the stability of clamping in the clamping slot 3 .

The notches 211 on the two clamping edges 21 are arranged in a staggered arrangement, and the length of the notches 211 is smaller than the length of the clamping protrusions 212 . With this structure, the entire bottom plate 2 is provided with the clamping protrusions 212 in the longitudinal direction for clamping and positioning, and the stability of the clamping between the bottom plate 2 and the clamping slot 3 is improved.

A sponge layer is compounded on the side of the bottom plate 2 facing away from the sealing wire 1 , that is, the side of the bottom plate 2 facing the bottom wall of the slot 3 . This structure can significantly improve the tightness of the cooperation between the sealing top strip and the clamping groove 3 . As another embodiment, the sponge layer, the bottom plate 2 and the card slot 3 are of a separate structure, which is directly cushioned between the bottom plate 2 and the bottom wall of the card slot 3 to facilitate later disassembly.
