Description

Technical Field

[0001] The utility model belongs to the technical field of sealing and decoration, in particular to a foldable internal corner decorative sealing strip. Background Art

[0002] Many of the internal angles formed by window frames, door frames, cabinets, countertops, etc. with walls are not beautiful and need to be covered and decorated. At the same time, the internal angles between window frames and door frames and walls will cause air leakage and dust leakage due to the gaps, so they also need to be sealed. The existing internal angle strips are all in a fixed right-angle shape and are fixed to two vertical walls with adhesive backing. The actual angles of wall corners or other internal angles may be greater than or less than 90 degrees. Especially when it is greater than 90 degrees, the fit will not be tight, which will affect the sealing and decorative effects. Over time, it will also cause the decorative strips to warp and fall off. This solid fixed-shape internal angle strip has a large overall weight, and it will often fall off after being pasted on the vertical and top internal angles for a long time.

[0006] A threading barrel with a long threading opening on one side is provided between the bottom surface of the flexible decorative body and the supporting body.

[0007] The flexible decorative body is in the shape of an inwardly concave or outwardly convex arc, and is composed of a single arc segment or multiple wave arc segments.

[0008] The support structure is a single reinforcement, a straight double reinforcement or an arc double reinforcement.

[0009] The angle of the V-shaped groove is 45 degrees.

[0010] The threading barrel is a circular, oval or U-shaped thin-walled threading barrel.

[0011] Advantages of this utility model:

[0012] The foldable internal corner decorative sealing strip of the utility model has two V-shaped grooves formed on the foldable sealing body and the inner closing body, so that the sealing body can be freely fitted according to the angles of the two sides of the internal corner after being folded, and is firmly and stably bonded to the internal corner surface through the double-sided adhesive to form a seal; the decorative body can completely cover the sealing body, and has a variety of shapes similar to goose wings or waves, with very good decorative effects.

[0020] The specific implementation of the present utility model is further described below with reference to the accompanying drawings.

[0021] like Figure 1-7 As shown, the foldable internal corner decorative sealing strip of the utility model is characterized in that it includes a flexible decorative body 1, a support body 2 vertically connected to the bottom surface of the flexible decorative body 1, an inner closing body 4 vertically connected to the bottom of the support body 2, two folding sealing bodies 3 connected to the left and right ends of the inner closing body 4 respectively through V-shaped grooves 5, and a backing glue 6 arranged on the outside of the two folding sealing bodies 3 and the inner closing body 4.

[0022] A threading barrel 7 with a threading opening 8 on one side is provided between the bottom surface of the flexible decorative body 1 and the support body 2 .

[0023] The flexible decorative body 1 is in the shape of an inwardly concave or outwardly convex arc, and is composed of a single arc segment or multiple wavy arc segments.

[0024] The support body 2 has a structure of single reinforcement, straight double reinforcement or arc double reinforcement.

[0025] The angle of the V-shaped groove 5 is 45 degrees.

[0026] The threading barrel 7 is a circular, oval or U-shaped thin-walled threading barrel.

[0027] like Figure 1 It is the unfolded shape of the corner decorative sealing strip, an infinitely extended foldable elastic cross-section structure.

[0028] The flexible decorative body 1, the supporting body 2, the folding sealing body 3 and the inner closing body 4 are connected to form a whole. Figure 2 The flexible decorative body 1 is in the shape of an inwardly concave or outwardly convex arc, and is composed of a single arc segment or multiple wave arc segments. It overlaps with the intersection surfaces on both sides and serves as a decoration and the first seal.

[0029] The center part of the support body 2, its upper and lower parts are respectively connected vertically with the flexible decorative body 1 and the inner closed body 4, as the support of the decorative body 1, the structure is single rib or straight double rib or arc double rib, such as Figure 3 , straight double reinforcement support is more stable, and arc double reinforcement support is elastic and retractable. In addition, the support body 2 adopts a single reinforcement or double reinforcement support structure to reduce weight and reduce the possibility of falling off.

[0030] The left and right ends of the inner closing body 4 are respectively connected to the two folding sealing bodies 3 through a V-shaped groove 5, so that the two folding sealing bodies 3 can be flipped and folded inward. The angle of the V-shaped groove 5 is 45 degrees, so that the angle between the two folding sealing bodies 3 can be arbitrarily changed between 180 degrees and slightly less than 90 degrees. After the two folding sealing bodies 3 are folded to 90 degrees, the left and right ends of the flexible decorative body 1 exceed the ends of the folding sealing bodies 3, covering the folding sealing bodies 3. The outside of the folding sealing bodies 3 and the inner closing body 4 is affixed with adhesive 6 to play a bonding role.

[0031] Figure 4The folding sealing body 3 and the inner closing body 4 of the foldable internal corner decorative sealing strip form two V-shaped grooves 5, so that the folding sealing body 3 can be freely fitted according to the angles of the two sides of the internal corner after folding, and a firm and stable bonding with the internal corner surface is achieved through the double-sided adhesive 6 to form a seal; the angle of the V-shaped groove 5 is 45 degrees, and the elasticity of the material makes the sealing strip more adaptable to internal corners less than 90 degrees; the inner closing body 4 and the two sides of the internal corner form a triangular enclosed space, which can alleviate wind pressure and enhance the sealing effect; after folding, the two ends of the flexible decorative body 1 respectively cover their corresponding two folding sealing bodies 3 and overlap on the pasting surface, and the elasticity of the material is used to make the flexible decorative body 1 in close contact with the two sides of the internal corner, thereby forming another seal at the end, which can further enhance the sealing effect; the arc shape of the flexible decorative body 1 can adapt to its elastic deformation and produce a good decorative effect from the outside. The support body 2 effectively supports the arc-shaped flexible decorative body 1, making the structure of the entire decorative sealing strip more stable and simplified, reducing weight and saving materials.

[0032] like Figure 5 A circular, oval or U-shaped thin-walled wire threading barrel 7 with a long wire threading opening 8 on one side is added to the upper part of the support body 2. The wire threading barrel 7 is connected to the flexible decorative body 1, which can realize a decorative strip for threading wires in the corners of the wall. The folding sealing bodies 3 on both sides also have a foldable function that can adapt to various corner angles. The U-shaped wire threading barrel has a larger wire threading cross-sectional area. The flexible decorative body 1 with a single arc or multiple arcs also plays a different decorative role.

[0033] The foldable internal corner decorative sealing strip of the utility model adopts new elastic materials such as TPE, TPR, PVC or EPDM, which have good strength and ductility as well as good heat resistance and corrosion resistance, ensuring the required elasticity and durability of the tearable sealing strip when the door is closed and sealed and pressed.
