Description

Technical Field

[0001] This utility model relates to the field of edge banding technology, specifically to an irregularly shaped edge banding strip with a self-locking structure. Background Technology

[0002] Edge banding is widely used in the custom cabinet or wardrobe furniture industry. The wood boards that are shipped from the factory are often only polished and compacted, and the edges of the wood boards cannot be flat. In particular, the edge banding strips for custom cabinets and wardrobes have higher requirements. They need to match the grain of the wood board and fit tightly to the thickness of the wood board. Gaps will cause customer complaints.

[0003] Currently, the width of edge banding strips is either custom-made or standard, which easily leads to gaps with the edges of the wood panels, affecting both aesthetics and lifespan. For example, CN214156729U discloses an irregularly shaped edge banding strip, characterized by its fixed installation on the circumferential surface of the side wall of the decorative panel. The edge banding strip includes a PVC strip and PU strips fixed at both ends of the PVC strip. The PU strip has semi-circular protrusions, each 5mm wide and 1.5mm high. While the PU strip is particularly soft and harmless to human skin, and its height is flush with the panel, resulting in an aesthetically pleasing design and reduced material waste, the fixed distance between the protrusions in this design cannot effectively accommodate slightly wider or narrower wood panel edges, failing to provide a complete clamping and tight fit, thus affecting the overall integrity and aesthetics of the wood panel.

[0004] Therefore, in order to address the above problems, the applicant needs to design an irregularly shaped edge banding strip with a self-locking structure to solve the problem. Utility Model Content

[0005] The purpose of this utility model is to provide an irregularly shaped edge banding strip with a self-locking structure to solve the problem mentioned in the background art that the edge banding strip cannot completely fit the edge of the wooden board, easily leaving gaps and resulting in an incomplete and unsightly appearance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an irregularly shaped edge banding strip with a self-locking structure, comprising an irregularly shaped edge banding strip body and an edge banding strip frame. The irregularly shaped edge banding strip body has an infinite length and is coiled into a circle. The outer side of the irregularly shaped edge banding strip body is provided with a first adhesive and a second adhesive, and the inner side of the irregularly shaped edge banding strip body is provided with an inner adhesive. The first adhesive is adhered to the second adhesive, and the second adhesive is adhered to the edge banding strip frame. The edge banding strip frame has multiple elliptical openings evenly distributed inside, and each opening is provided with a spiral mechanism.

[0007] Furthermore, the spiral mechanism consists of a circular disc and hollow straight rods on both sides, and a knob is rotatably connected inside the spiral mechanism.

[0008] Furthermore, a one-way ratchet is connected to the knob, the shaft of the one-way ratchet is fixedly connected to the winding shaft, and a steel wire rope is wound on the winding shaft.

[0009] Furthermore, the steel wire ropes pass through the hollow straight rods at both ends of the spiral mechanism, and their ends extend out of the hollow straight rods and are fixedly connected to the clamping plates.

[0010] Furthermore, the clamping plate is slidably connected in the slide groove, which is opened on the back of the edge sealing frame, and the edge sealing frame is in the shape of an "I".

[0011] Furthermore, the width of the clamping plate is less than the width of the recesses on both sides of the edge sealing frame, and the initial state of the clamping plate is in close contact with the inner surface of the edge sealing frame.

[0012] Furthermore, the grooves are formed at the upper and lower ends of the elliptical opening, and the grooves are not connected to the opening. There are multiple openings, and the distance between the multiple openings is equal. Each opening has a groove at both ends, and the number of openings is the same as the number of screw mechanisms.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model protects the edge banding frame by setting multiple surface adhesives and inner adhesives inside the irregular edge banding strip body. When the edge banding strip needs to be used, the inner adhesives need to be peeled off first so that the edge banding strip frame can be wrapped around the edge of the wood board that needs to be edged, ensuring the overall aesthetics of the wood board. Moreover, the pattern of the surface adhesive can be consistent with the pattern of the wood board that needs to be edged, resulting in high integrity and high aesthetics.

[0015] By evenly setting multiple oval openings within the edge banding frame, and by setting knobs within each opening, rotating the knobs drives the relative movement of the steel wire ropes at both ends and the clamping plates, the edges of the wooden board, which are slightly thinner than the edge banding frame, are clamped, thus better ensuring the overall aesthetics of the wooden board that needs to be edged.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5 As shown, this utility model discloses an irregular edge banding strip with a self-locking structure, comprising an irregular edge banding strip body 1 and an edge banding strip frame 2. The irregular edge banding strip body 1 has an unlimited length and is coiled into a circle. The outer side of the irregular edge banding strip body 1 is provided with adhesive first 101 and adhesive second 102, and the inner side of the irregular edge banding strip body 1 is provided with inner adhesive 103. Adhesive first 101 is bonded to adhesive second 102, and adhesive second 102 is bonded to the edge banding strip frame 2. Multiple elliptical openings 201 are evenly opened inside the edge banding strip frame 2, and each opening 201 is provided with a spiral mechanism 3.

[0026] The adhesive on the inner wall of the edge banding frame 2 after the inner adhesive 103 is torn off is used to wrap the wood board that needs to be edge-sealed, thereby sealing the edge and improving the overall aesthetic appearance of the wood board.

[0027] The spiral mechanism 3 consists of a circular disc and hollow straight rods on both sides. A knob 301 is rotatably connected inside the spiral mechanism 3. A one-way ratchet 304 is connected to the knob 301. The shaft of the one-way ratchet 304 is fixedly connected to the winding shaft 305. A steel wire rope 302 is wound on the winding shaft 305. The steel wire rope 302 passes through the hollow straight rods at both ends of the spiral mechanism 3, and the ends of the ropes extend out of the hollow straight rods and are fixedly connected to the clamping plate 303. The clamping plate 303 is slidably connected in the slide groove 202. The slide groove 202 is opened on the back of the sealing strip frame 2. The sealing strip frame 2 is shaped like an "I".

[0028] By rotating the knob 301 inside the spiral mechanism 3, the winding shaft 305 is driven to rotate, causing the steel wire ropes 302 on both sides to move relative to each other. This allows the clamping plates 303 on both sides to clamp the edge of the wooden board, resulting in a better edge sealing effect. It can also be used when the thickness of the wooden board is less than that of the edge sealing strip 2.

[0029] The width of the clamping plate 303 is less than the width of the recesses on both sides of the edge sealing frame 2, and the clamping plate 303 is initially in close contact with the inner surface of the edge sealing frame 2. The sliding groove 202 is opened at the upper and lower ends of the elliptical opening 201, and the sliding groove 202 is not connected to the opening 201. There are multiple openings 201, and the distance between the multiple openings 201 is equal. Each opening 201 has a sliding groove 202 at both ends. The number of openings 201 is the same as the number of screw mechanisms 3.

[0030] After using the knob 301 to clamp the clamping plate 303 to the edge of the wooden board, the adhesive 102 can be used again to cover the multiple openings 201 to ensure the integrity of the edge sealing.

[0031] Working principle: When it is necessary to use the irregular edge banding strip body 1, first tear off the inner glue 103 to expose the edge banding strip frame 2, and then wrap the edge banding strip frame 2 around the edge of the wooden board that needs to be edge banded.

[0032] Next, peel off the first adhesive 101 one by one to expose the surface of the second adhesive 102 with a pattern that matches the wood board. If the size of the edge banding frame 2 is just right to match the edge of the wood board, no further operation is needed, and the edge banding operation is complete.

[0033] When the width of the edge banding frame 2 is slightly larger than the width of the edge to be banded, it needs to be adjusted (in which case the adhesive 102 needs to be peeled off), exposing the opening 201 and the spiral mechanism 3. By turning the knob 301, the steel wire ropes 302 on both sides and the clamping plate 303 are brought closer together to clamp the edge of the wooden board that needs to be banded. After the operation is completed, the adhesive 102 is re-covered on the edge banding frame 2 to ensure the integrity and aesthetics of the edge banding.

[0034] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
