Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sealing, and particularly relates to a sealing strip for a hand-tearable and press-fixed door. Background Art
[0002] House doors, such as indoor wooden doors, are very commonly used in home decoration. Sealing strips are generally used between the door leaf and the door frame for sound insulation and reducing the impact when closing the door. Existing sealing strips are of fixed sizes, such as Figure 7 , and cannot adapt to the changes in the gaps caused by processing and assembly errors between the door leaf and the door frame. The gaps of wooden doors produced by each manufacturer are also different. Using such sealing strips of fixed sizes for sealing, it will prevent the door from closing when encountering a small gap, and there will be a situation of poor sealing when encountering a large gap; moreover, existing sealing strips are fixed by adhesive backing, which is troublesome to install and is very likely to be skewed; in addition, it is even more troublesome to deal with the remaining glue and residual adhesives on the window frame when replacing and tearing off old sealing strips.

[0018] The following further describes the detailed implementation manners of the present utility model with reference to the drawings.
[0019] As Figures 1-6 shown, a sealing strip for a hand-tearable press-fixable door of the present utility model is characterized in that it includes N seal bodies of an arched structure connected in sequence. Each seal body is connected to the adjacent seal body below it at the left and right shoulders and respectively forms N compression cavities. A tear groove 6 is provided on the outside of the connection of the left and right shoulders of each two adjacent seal bodies. A barbed structure 7 is provided at the lower part of the N seal bodies of the arched structure, and barbed strips 7.1 are provided on both sides of the barbed structure 7.
[0020] The tear groove 6 is manually torn at the connection with the compression cavity.
[0021] The seal body of the arched structure includes a straight-foot arched structure seal body, an inclined-foot arched structure seal body, or an arc-shaped arched structure seal body.
[0022] The described sealing body with N arched structures, where N is a natural number ranging from 3 to 5.
[0023] Such as Figure 1 , it is a five - layer door - used hand - tear and press - install sealing strip. This sealing strip has five sealing bodies, namely sealing body Ⅰ1, sealing body Ⅱ2, sealing body Ⅲ3, sealing body Ⅳ4, and sealing body Ⅴ5. Each sealing body is an arched structure and is connected to the adjacent sealing body below at the left and right shoulders, respectively forming compression cavities Ⅰ1.1, Ⅱ2.1, Ⅲ3.1, Ⅳ4.1, Ⅴ5.1. A tear - off groove 6 is provided on the outside of the connection at the left and right shoulders. The tear - off groove 6 forms a thin - wall connection with the compression cavity at the connection and can be torn by hand, thus forming sealing bodies with five height dimensions. The arched sealing body and the compression cavity make each sealing body more elastic. The upper surface of each arched sealing body is the sealing surface, which closely fits with the door frame 9 to form a seal. Such as Figure 2 (sealing and installation diagram when it is a three - layer sealing body); the lower part of the sealing body Ⅰ1 is a barbed structure 7. Barbed strips 7.1 are provided on both sides of the barbed structure 7. The direction of the barbed strips 7.1 is convenient for pressing in. During installation, the barbed structure 7 is pressed into the door - frame installation groove 8. The lower plane of the sealing body Ⅰ1 fits with the door frame 9. By compressing the barbed strips 7.1, a swelling force is formed to fix the sealing body. When the door leaf 10 is closed, the door leaf 10 fits with the arched outer surface of the sealing body, compressing the sealing body. The elastic reaction force generated by the compression deformation of the arched structure and the compression cavity of the sealing body forms a seal.
[0024] The present utility model adopts new elastic materials such as TPE, TPR, or ethylene - propylene diene monomer, etc., which have good strength ductility, good heat resistance, and corrosion resistance, ensuring the elasticity and durability required for the tear - off sealing body in the closed - door sealing and press - fixation states.
[0025] Due to the structural design of the door frame 9, the door - frame installation groove 8 may be biased to one side. Then the barbed structure 7 of this hand - tear and press - install sealing strip needs to be biased to one side. Such as Figure 3 .
[0026] The hand - tear and press - install door - used sealing strip can have similar structures such as straight - foot arched structures (such as Figure 4 ), inclined - foot arched structures (such as Figure 5 ), and arc - arched structures (such as Figure 6 ) on the upper - part tear - off arched structure. They all have the structural characteristics of arches and compression cavities, the connection method of mutual stacking, and the hand - tear function; at the same time, on the support structure of the sealing body at the bottommost layer, there can also be Figure 4 , Figure 5 , Figure 6 among the four changes to adapt to different elastic requirements. These sealing bodies all have a unified lower - part barbed structure 7 and all have the function of press - install.
[0027] The sealing strip for the hand-tear press-fixed door of the present utility model is formed by stacking multiple (usually 3 to 5 layers) interconnected hollow arched sealing bodies. A tear groove 6 is provided between each layer. According to the required height of the sealing body, it is manually torn at the tear groove 6 to adapt to the gaps between door leaves 10 and door frames 9 of different sizes. The installation of the sealing body adopts a barbed structure 7 at the lower part, and is pressed into the door frame installation groove 8 by using the elastic tension of the material to be tightened and fixed. At the same time, it is very convenient to replace, ensuring the straightness of the installation of the sealing body and being very convenient for installation and disassembly. The present utility model adopts PT material, and uses its good strength ductility, good heat resistance and corrosion resistance to ensure the elasticity and durability required for sealing and pressing.
