Description
Technical Field
[0001] This utility model belongs to the field of sealing strip technology, specifically relating to a sealing strip for sealing glass in a wall cabinet. Background Technology
[0002] Wall-mounted cabinets are widely used in offices, showrooms, and homes, typically consisting of a cabinet body and glass panels embedded in it. During installation, two glass panels are usually joined together along the wall to create a seamless, aesthetically pleasing, transparent glass wall. However, a gap of a certain width usually exists at the joint of the glass panels. This gap not only affects the overall visual appeal and aesthetics but also easily becomes a channel for air, dust, or impurities to enter the cabinet, thus affecting the cleanliness and lifespan of the items inside. Therefore, effectively sealing the gaps between the glass panels is a common technical challenge in current technology.
[0003] Existing sealing methods mainly include applying adhesive and pasting sealing tape, but these methods suffer from problems such as complex construction, unstable sealing performance, and poor aesthetics. For example, using silicone-based materials to seal gaps often leads to seal failure due to material aging and poor adhesion; while when using ordinary sealing tape, the smooth glass surface makes the tape prone to falling off, and stable installation cannot be achieved at the joint angle of the gap, further resulting in unsatisfactory sealing effects.
[0004] In addition, existing sealing structures often fail to consider the geometric fit between the glass panel mating angle and the sealing strip structure, resulting in a cumbersome installation process, easy loosening or displacement of the sealing strip, poor structural stability after long-term use, and affecting the overall service life and sealing effect of the cabinet. Utility Model Content
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a sealing strip for sealing glass in wall-mounted cabinets. This sealing device has a reasonable structure, is easy to install, has reliable sealing performance, and is aesthetically pleasing. It is suitable for sealing scenarios between glass panels in wall-mounted cabinets, and solves the technical problems of complex construction, easy detachment, and poor sealing in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A sealing strip for sealing glass in a wall cabinet includes a sealing strip body placed between a first glass plate and a second glass plate. The sealing strip body includes a trapezoidal body with a hollow interior and one open side. The two sides of the trapezoidal body are in contact with the sealing slopes of the first and second glass plates, respectively. A forward extension is vertically arranged on the trapezoidal body away from the open end. A cylindrical part is provided at the end of the forward extension. The cylindrical part is tangent to the sealing slopes of the first and second glass plates, respectively. Barbs are symmetrically arranged on both sides of the forward extension. The barbs are inclined towards one side of the trapezoidal body and are used to prevent the sealing strip body from falling off.
[0008] Furthermore, symmetrical protrusions are provided on both sides of the open portion of the trapezoidal main body, and a sliding groove is vertically opened on the side of the two protrusions that are close to each other.
[0009] Furthermore, a rigid sealing plate is slidably installed between the two grooves, the rigid sealing plate being used to maintain the opening angle of the trapezoidal body.
[0010] Furthermore, the sealing strip body is integrally formed.
[0011] Furthermore, the open end face of the trapezoidal body is flush with the inner surfaces of the first and second glass plates.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention features a beveled joint at the joint edges of the first and second glass panels, with the sealing strip body forming a mating angle with the beveled joint. This allows the sealing strip body to be firmly inserted into the angle between the glass panels. This structure not only improves the fit between the sealing structure and the glass panels but also creates a visually appealing beveled transition at the joint, enhancing the overall aesthetics of the wall-mounted cabinet. It effectively solves the problems of abrupt glass panel joints and poor overall coordination after assembly in existing technologies.
[0014] This invention features barbs at a 45° angle on both sides of the forward extension of the sealing strip body. During installation, the barbs slide smoothly into the glass joint gap and then lock against the glass plates after insertion, thus achieving self-locking and limiting of the sealing strip body and preventing the sealing structure from loosening or falling off during use. This structure improves the structural stability of the sealing strip during long-term use and overcomes the problems of easy aging and detachment of traditional adhesive or glue-filled sealing methods.
[0015] This invention features a cylindrical section on the open end face of the sealing strip body. The cylindrical section is made of flexible TPE material, which can form elastic contact with the inclined glass surfaces on both sides after insertion and generate a certain amount of compressive force, thereby achieving flexible compression sealing inside the glass joint and improving sealing reliability. This cylindrical structure effectively improves the gap leakage problem caused by insufficient deformation in traditional sealing structures.
[0016] This invention features two symmetrical raised strips inside the opening of a trapezoidal main body. The inner side of each raised strip has a sliding groove, within which a rigid sealing plate is slidably installed. The rigid sealing plate effectively supports and limits the opening angle of the trapezoidal main body after installation, preventing instability of the sealing structure due to deformation under stress. Furthermore, the rigid sealing plate seals the internal cavity of the sealing strip, preventing dust and foreign matter from entering and causing blockages, effectively extending the service life of the sealing structure. This design solves the problems of deformation and internal contamination caused by insufficient strength in existing sealing structures.
[0017] This invention employs a two-component integrated molding process, combining rigid PVC and flexible TPE materials to form the support structure and sealing contact area, respectively. While achieving rigid structural support, it also possesses elastic sealing capability. The overall structure is lightweight, easy to process, and convenient to assemble. This composite structure overcomes the problems of existing sealing components having a single structure, insufficient rigidity, or lack of flexible support, thereby improving the overall sealing performance and assembly efficiency.
[0018] This utility model ensures that the open end face of the trapezoidal main body is flush with the inner surfaces of the first and second glass plates, so that the sealing structure forms a unified plane with the inner surface of the glass, avoiding the formation of recessed dust accumulation areas in the gaps, while improving the overall visual coordination and spatial sealing effect of the wall cabinet; this structure significantly optimizes the phenomenon of traditional sealing components protruding or retracting on the inner side, forming cleaning dead corners.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0026] Example 1:
[0027] refer to Figures 1-4 As shown, a sealing strip for sealing glass in a wall cabinet includes a sealing strip body 3 placed between a first glass plate 1 and a second glass plate 2; both the first glass plate 1 and the second glass plate 2 are high-transmittance tempered glass with a thickness of 6mm, and their outer edges are pre-set with buttressing bevels 11 at an angle of 120°; the sealing strip body 3 includes a trapezoidal body 31, which is integrally molded from rigid PVC material with a hardness rating of Shore D. 75, possessing good weather resistance and compression deformation recovery capability; the trapezoidal main body 31 is hollow inside, with an open structure extending longitudinally along one side, forming a "U"-shaped interlocking channel for accommodating and sealing the glass plate joint area; the two sides of the trapezoidal main body 31 respectively contact the sealing slopes of the first glass plate 1 and the second glass plate 2, forming a wedge-shaped insertion space through the slope contact structure to enhance assembly stability; the trapezoidal main body 31 has a forward extension 34 vertically arranged away from the open end, the forward extension 34 is made of the same material, with a width of 4mm and a thickness of 1.5mm, and its length direction is consistent with the trapezoidal main body 31 to enhance the support effect of the sealing strip during the assembly process; the forward extension 34 The end is provided with a cylindrical part 35, which is made of high elastic TPE material and has a diameter of 5mm. It has elastic deformation capability and can be tangent to the sealing slope of the first glass plate 1 and the second glass plate 2 after assembly to form a certain contact pressure to ensure tight sealing of the gap. The front extension 34 is symmetrically provided with barbs 36 on both sides. The barbs 36 and the front extension 34 are integrally injection molded using the same molding mold. The barbs 36 are inclined at an angle of 45° towards the trapezoidal body 31 and have a length of 3mm. The tip has a serrated anti-slip ridge, which is used to form a micro-embedded fixing position with the glass surface after the sealing strip is inserted into the angle position, to prevent the sealing strip body 3 from loosening or falling off during long-term use.
[0028] refer to Figure 2 and Figure 3As shown, the trapezoidal main body 31 has symmetrical protrusions 32 on both sides of the open end. The protrusions 32 are embedded limiting structures, made of the same material and integrally formed. The width of one side is 1mm and the height is 2mm. The two protrusions 32 are vertically provided with grooves 33 on the side that are close to each other. The grooves 33 have an opening width of 3mm and a depth of 4mm. The inner surface of the grooves is provided with fine friction texture to improve the sliding and fitting stability of the hard sealing plate.
[0029] refer to Figure 2 and Figure 4 As shown, a rigid sealing plate 4 is slidably installed between the two sliding grooves 33. The rigid sealing plate 4 is made of 2mm thick ABS engineering plastic, which has high rigidity and high temperature resistance. Its length direction is consistent with the sealing strip body 3, and it is installed in the sliding groove 33 by sliding in. The rigid sealing plate 4 is used to keep the opening angle of the trapezoidal body 31 unchanged, and at the same time, it forms an effective seal for the opening after assembly, preventing air and dust from entering the hollow cavity and causing blockage or affecting the deformation of the sealing structure.
[0030] refer to Figure 3 As shown, the sealing strip body 3 is integrally molded; the whole adopts a two-component injection molding process, combining rigid PVC and flexible TPE materials. Through mold injection, the cylindrical part 35 and the main body have a composite structure with rigid and flexible material properties, so that the structural strength and sealing performance are taken into account during the installation process, meeting the needs of high-strength assembly and long-term use of the wall cabinet.
[0031] refer to Figure 1 and Figure 4 As shown, the open end face of the trapezoidal main body 31 is flush with the inner side of the first glass plate 1 and the second glass plate 2. This structure can achieve a smooth transition between the sealing structure and the inner surface of the glass after the glass is joined, improving the overall visual appeal. At the same time, it avoids dust accumulation and dust ingress caused by the exposed edges of the glass, and improves the overall airtightness and aesthetics of the wall cabinet.
[0032] Example 2:
[0033] In this embodiment, the first and second glass panels are made of 6mm thick high-transmittance tempered glass, with the edges processed to form a 120° inclined bevel. The main body of the sealing strip is made of rigid PVC material, extruded in one piece, with a thickness of 3mm. Its shape is consistent with the glass joint angle and has a trapezoidal structure. After insertion, the main body of the sealing strip is stably embedded between the glass panels by its own weight and the wedge-shaped space. The joint forms a natural inclined transition, which effectively improves the visual consistency of the cabinet when viewed from the front and the smoothness of light refraction.
[0034] Comparative Cases:
[0035] The glass panels are spliced at right angles and ordinary sealing strips are pasted on. There is no wedge-shaped fitting structure. The edges of the sealing strips are exposed and it is difficult to blend naturally with the glass. Visually, they form obvious dividing lines and are prone to dust accumulation, resulting in poor overall decorative effect.
[0036] Example 3:
[0037] In this embodiment, barbs with an inclination angle of 45° and a length of 3mm are arranged on both sides of the forward extension of the sealing strip body. The barbs form a reverse anchoring effect with the glass slope to achieve structural self-locking. PA66 material is used to enhance wear resistance and elasticity. During installation, it is inserted from the open end. After insertion, the barbs automatically lock into the inside of the glass joint. The friction force provides stable limiting and prevents the sealing strip from sliding or falling out under the conditions of gravity, vibration or thermal expansion and contraction.
[0038] Comparative Cases:
[0039] Existing foam-type self-adhesive sealing strips lack a mechanical locking structure, making them prone to loosening and warping under long-term gravity or external disturbances, resulting in a short service life and frequent maintenance.
[0040] Example 4:
[0041] In this embodiment, an elastic cylindrical part is provided at the end of the forward extension of the trapezoidal sealing strip. The part is made of flexible TPE material and has a diameter of 5mm. It is inserted after the glass joint corner forms an angled area. The cylindrical part undergoes elastic deformation due to the size of the glass angle, generating a radial reaction force. It continuously applies pressure to the inclined glass surface to achieve a flexible seal, blocking the intrusion path of air and dust. It is suitable for environments with high cleanliness requirements, such as museums and laboratory cabinets.
[0042] Comparative Cases:
[0043] Existing seals made of ordinary plastic lack elastic deformation buffer zones, resulting in gaps at the sealing contact surfaces. As they age, the seals often fail to tighten, allowing dust to enter the cabinet and contaminate the exhibits.
[0044] Example 5:
[0045] In this embodiment, two symmetrical raised strips are provided inside the trapezoidal main body opening. The raised strips are 1mm wide and 2mm high, and a sliding groove is opened. An ABS rigid sealing plate with a width of 2.8mm and a thickness of 2mm is installed in the sliding groove. After the rigid sealing plate is embedded in the sliding groove, it forms a structural support surface with the edge of the opening. It can withstand the external torque along the installation direction and keep the opening angle constant, avoiding deformation of the sealing strip due to manual insertion or force. At the same time, it prevents foreign objects from entering the sealing strip cavity and extends the structural life.
[0046] Comparative Cases:
[0047] Traditional hollow sealing structures lack supporting components, making them prone to collapse or deformation at the opening due to compression or external forces. This leads to the failure of the seals on both sides of the slope and the accumulation of dust at the open area, making cleaning difficult.
[0048] Example 6:
[0049] This embodiment employs a two-component injection molding process, simultaneously injection molding high-hardness PVC (Shore D 75) and flexible TPE to form a composite sealing strip with structural support and sealing contact functions. The rigid part constitutes the trapezoidal main body and the forward extension structure, while the flexible part constitutes the cylindrical sealing structure and the sliding insertion part. The overall structure is rigidly supported and does not deform under stress, while the contact part flexibly fits, achieving reliable sealing while improving assembly efficiency.
[0050] Comparative Cases:
[0051] Single-material PVC sealing strips require manual adjustment of deformation during installation to achieve proper fit, resulting in unstable sealing performance. Furthermore, repeated insertion and removal can lead to structural fatigue and cracking, and poor reusability.
[0052] Example 7:
[0053] In this embodiment, after the first glass plate and the second glass plate are spliced together, the open end face of the trapezoidal main body of the sealing strip is processed by precision cutting technology to be flush with the inner side of the two glass plates, forming a continuous plane of the overall inner surface; this structure avoids the sealing element from being recessed or protruding, improves internal cleanliness and visual integration effect, and is particularly suitable for occasions such as display cabinets and wall-mounted bookcases that require high appearance consistency.
[0054] Comparative Cases:
[0055] Traditional sealing strips often have bulges or depressions on the inside due to processing deviations or different insertion depths, forming dead corners for dust accumulation and reducing the cleanliness of internal items and the aesthetics of the cabinet.
[0056] The working principle of this utility model is as follows: First, the first glass plate 1 and the second glass plate 2 are clamped into the groove reserved in the cabinet to maintain their position stability. A butt joint bevel 11 is provided on the mating surface of the first glass plate 1 and the second glass plate 2 to improve the aesthetics of the splice. After the butt joint, the splice of the first glass plate 1 and the second glass plate 2 forms an angle that is consistent with the angle of the trapezoidal main body 31. Then, the sealing strip main body 3 is inserted into the angle. Since the barbs 36 on both sides are inclined towards the opening, the sealing strip main body 3 can be smoothly installed inward. The cylindrical part 35 is installed until it is tangent to the inclined surfaces 11 on both sides and is subjected to a certain degree of compression. The open end face of the trapezoidal body 31 is flush with the inner side of the first glass plate 1 and the second glass plate 2. At this time, the barb part 36 can prevent the sealing strip body 3 from falling off, thereby ensuring stability and effectively filling the splicing gap between the second glass plate 2 and the first glass plate 1, improving the aesthetics. At the same time, the gap is sealed from the outside to the inside by the cylindrical part 35, the barb part 36 and the side of the trapezoidal body 31 to prevent air and dust from entering the cabinet through the outside.
[0057] After the sealing strip body 3 is initially installed, select a suitable width of rigid sealing plate 4 and insert the rigid sealing plate 4 into the two sliding grooves 33 through the top. On the one hand, it can seal the opening of the trapezoidal body 31 to prevent foreign objects from entering and causing blockage. On the other hand, it can maintain the angle of the opening of the trapezoidal body 31 so that its side can make perfect contact with the mating inclined surface 11. At the same time, it can prevent the trapezoidal body 31 from deforming due to compression, resulting in an incomplete seal.
[0058] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
