Description

Technical Field

[0001] This utility model belongs to the field of door panel technology, and specifically relates to a door panel structure that accelerates bonding. Background Technology

[0002] As a crucial component of buildings, the structural design and manufacturing process of apartment doors directly impact product performance and production efficiency. Traditional apartment doors typically consist of an inner frame, front and rear side panels, and front and rear decorative panels. The side panels are welded to the inner frame structure, while the decorative panels are glued to the side panels using sealant. While this structure is simple and easy to implement, it suffers from the significant problem of slow sealant drying, leading to extended production cycles.

[0003] In traditional residential door manufacturing, the bonding between the decorative panel and the side panel relies on sealant. Because the sealant joint is usually closed or semi-closed, air circulation is poor, significantly slowing down the sealant's curing speed. The sealant's curing process requires the absorption of moisture from the air, progressing gradually from the surface inwards. At room temperature (25℃, 50% humidity), it typically takes 24-48 hours to fully cure, and in low-temperature, high-humidity environments, this can extend to over 72 hours. The tight fit between the decorative panel and the side panel further restricts moisture penetration and evaporation, causing the sealant to remain wet for extended periods, affecting subsequent door processing and safety during use.

[0004] To address the aforementioned issues, this application provides a door panel structure that accelerates bonding, aiming to improve the curing speed of the adhesive within the door panel structure. Utility Model Content

[0005] This invention provides a door panel structure that accelerates bonding, aiming to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A door panel structure for accelerating bonding includes: a support frame, a front baffle fixedly connected to the front side of the support frame, and a rear baffle fixedly connected to the rear side of the support frame. Both the front baffle and the rear baffle are provided with a plurality of baffle ventilation holes. A front panel is fixedly connected to the surface of the front baffle by adhesive, and a rear panel is fixedly connected to the surface of the rear baffle by adhesive. A snap-fit ​​plate is provided on both sides of the support frame.

[0007] Furthermore, the outer edge of the support frame is an outer frame, and several horizontal bars are arranged parallel to each other inside the outer frame. The outer frame and the horizontal bars are hollow inside and connected to each other. Several frame ventilation holes are opened on the outer frame and the horizontal bars respectively.

[0008] Furthermore, extension plates are respectively provided on both sides of the front baffle, the angle between the extension plates and the front baffle is a right angle, and a mating plate is provided at the end of the extension plate. The mating plate is positioned towards the middle of the front baffle and is used to abut against the rear baffle.

[0009] Furthermore, the snap-fit ​​plate includes: a side plate, a first limiting plate is provided on the front side of the side plate, and a second limiting plate is provided on the rear side. The side plate, the first limiting plate, and the second limiting plate form a snap-fit ​​groove, which is used to snap-fit ​​the front baffle, the rear baffle, and the rear panel. The distance between the first limiting plates on the two snap-fit ​​plates is adapted to the width of the front panel.

[0010] Furthermore, the front side of the snap-fit ​​plate is provided with a mounting plate facing opposite to the first limiting plate, the front side of the mounting plate is provided with a first mounting groove, and the rear side is provided with a second mounting groove.

[0011] Furthermore, a decorative panel is snapped between the first mounting slots on the two snap-fit ​​plates.

[0012] Furthermore, the second mounting groove is used to mount a rubber pad.

[0013] Compared with the prior art, the present invention has the following technical effects: 1. The door panel structure for accelerating bonding described in this utility model has several ventilation holes on the front and rear baffles. The presence of these ventilation holes significantly improves air circulation inside the door. In traditional residential doors, the sealant joints are closed or semi-closed, resulting in poor air circulation and a significant reduction in the curing speed of the sealant. This structure, however, allows air to flow better inside the door through the ventilation holes, enabling the sealant to come into more complete contact with moisture in the air during the curing process, thereby accelerating the curing process.

[0014] 2. The faster and more uniform glue curing process in the door panel structure of this utility model helps to ensure the bonding quality between the panel and the baffle. In traditional structures, the glue not drying for a long time will affect the bonding strength and thus affect the safety of the door. However, this structure accelerates the curing speed, allowing the glue to fully exert its bonding effect, ensuring a tight bond between the panel and the baffle, and enhancing the overall stability and safety of the door.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.

[0018] like Figure 1-4 As shown, a door panel structure for accelerating bonding includes: a support frame 1, a front baffle 2 fixedly connected to the front side of the support frame 1, and a rear baffle 3 fixedly connected to the rear side. Both the front baffle 2 and the rear baffle 3 have several ventilation holes 7. A front panel 4 is fixedly connected to the surface of the front baffle 2 with adhesive, and a rear panel 5 is fixedly connected to the surface of the rear baffle 3 with adhesive. Clip-on plates 6 are respectively provided on both sides of the support frame 1. The ventilation holes 7 on the front baffle 2 and the rear baffle 3 significantly improve air circulation inside the door. In traditional residential doors, the sealant joints are closed or semi-closed, resulting in poor air circulation and a significant reduction in the curing speed of the sealant. This structure allows air to flow better inside the door through the ventilation holes, enabling the sealant to come into more complete contact with moisture in the air during the curing process, thereby accelerating the curing process. A faster and more uniform adhesive curing process helps ensure the bonding quality between the baffle and the panel. In traditional structures, the adhesive not drying for a long time will affect the strength of the bond and thus affect the safety of the door. This structure, by accelerating the curing speed, allows the adhesive to fully exert its bonding effect, ensuring a tight bond between the panel and the baffle, and enhancing the overall stability and safety of the door.

[0019] like Figure 3-4As shown, the outer edge of the support frame 1 is an outer frame 101. Several horizontal strips 102 are arranged parallel to each other inside the outer frame 101. Both the outer frame 101 and the horizontal strips 102 are hollow and interconnected. Several frame ventilation holes 103 are respectively opened on the outer frame 101 and the horizontal strips 102. The hollow and interconnected interiors of the outer frame 101 and the horizontal strips 102, combined with the frame ventilation holes 103, create a more effective air circulation network. This allows air to not only enter the door body through the ventilation holes on the front baffle 2 and the rear baffle 3, but also to flow within the hollow structure of the support frame 1, allowing air to reach the sealant joints of all parts of the door more comprehensively. Compared to relying solely on the baffle ventilation holes 7, this design greatly increases the contact area and contact opportunities between air and sealant, thereby significantly accelerating the absorption of moisture from the air by the sealant and further promoting adhesive curing.

[0020] like Figure 2 As shown, extension plates 201 are respectively provided on both sides of the front baffle 2. The angle between the extension plates 201 and the front baffle 2 is a right angle. The end of the extension plate 201 is provided with a mating plate 202, which is positioned towards the center of the front baffle 2 and is used to abut against the rear baffle 3. The extension plates 201 on both sides of the front baffle 2 are set at right angles to the front baffle 2, and the mating plates 202 at the ends of the extension plates 201 abut against and are welded to the rear baffle 3, which makes the entire door panel form a stable frame-like structure. This frame structure can better distribute and withstand external forces. When the door panel is subjected to impact, compression, or various forces during daily use, the force can be evenly distributed through the welding points and frame structure, avoiding deformation or damage caused by local stress concentration, and greatly enhancing the overall structural strength and stability of the door panel. The design of the mating plate 202 provides clear positioning and support for the welding operation. During production, workers can easily align and weld the mating plate 202 with the rear baffle 3, reducing positioning difficulties and errors during assembly and improving assembly efficiency. This standardized design also facilitates automated production, contributing to increased production scale and standardization. The contact surfaces of the mating plate 202 and the rear baffle 3 provide excellent contact conditions for welding, making the welding process more stable and reliable. Welding parameters can be better controlled during welding, ensuring consistent and stable welding quality. Furthermore, due to the larger contact area, the welded connection strength is higher, reducing welding defects such as incomplete welds and leaks, and improving product yield.

[0021] like Figure 2As shown, the snap-fit ​​plate 6 includes: a side plate 601, a first limiting plate 602 is provided on the front side of the side plate 601, and a second limiting plate 603 is provided on the rear side. The side plate 601, the first limiting plate 602 and the second limiting plate 603 form a snap-fit ​​groove. The snap-fit ​​groove is used to snap-fit ​​the front baffle 2, the rear baffle 3 and the rear panel 5. The distance between the first limiting plates 602 on the two snap-fit ​​plates 6 is adapted to the width of the front panel 4.

[0022] The slots formed by the side panel 601, the first limiting plate 602, and the second limiting plate 603 can tightly engage the front baffle 2, the rear baffle 3, and the rear panel 5. This engaging method makes the connection between these components more secure and enhances the stability of the entire door structure. During daily use of the door, such as frequent opening and closing or impact from external forces, the engaging action of the slots can effectively resist various forces, prevent loosening or displacement between components, and ensure the integrity of the door structure. The two sides of the rear panel 5 are prone to warping due to various reasons (such as changes in environmental humidity, uneven drying of glue, etc.), affecting the appearance and performance of the door. The engaging action of the slots can effectively constrain the rear panel 5, firmly fixing it in the appropriate position and preventing warping of its two sides. This ensures that the door always maintains a flat and aesthetically pleasing appearance, improving the overall quality and visual effect of the product. In one specific embodiment, the upper and lower edges of the side panel 601 are welded to the extension plate 201 and the support frame 1 to achieve fixation.

[0023] like Figure 2 As shown, the front side of the snap-fit ​​plate 6 is provided with a mounting plate facing the opposite direction to the first limiting plate 602. The front side of the mounting plate is provided with a first mounting groove 604, and the rear side is provided with a second mounting groove 605.

[0024] like Figure 2 As shown, a decorative panel 8 is snapped between the first mounting slots 604 on the two snap-fit ​​plates 6. The snap-fit ​​of the decorative panel 8 between the first mounting slots 604 on the two snap-fit ​​plates 6 significantly enhances the overall aesthetic appearance of the structure. The decorative panel 8 can be made of different materials (such as wood, plastic, metal, etc.), in different colors and textures to match the surrounding environment and beautify the space, depending on the usage scenario and aesthetic requirements. The installation of the decorative panel 8 makes the snap-fit ​​plates 6 and the entire structure look more unified and complete. It can cover the connection gaps and unsightly parts between the snap-fit ​​plates 6 and other components, giving the entire structure a unified visual effect and enhancing the product's perceived quality.

[0025] In one specific embodiment, the second mounting groove 605 is used to install a rubber pad. The rubber pad has good elasticity and cushioning properties. When the door collides or rubs against the door frame during opening and closing, the rubber pad can act as a buffer, reducing impact and noise generation. This not only extends the service life of the door and related components but also provides a quiet and comfortable environment for the user.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
