Description

Technical Field

[0001] This utility model belongs to the field of cabinet door technology, specifically relating to a universal cabinet door with integrated handle. Background Technology

[0002] In the furniture manufacturing industry, cabinet doors, as an important component of various cabinets, have always been a focus of attention due to their structural design and installation methods. With the improvement of people's living standards, higher demands are being placed on the functionality, aesthetics, and ease of installation of cabinet doors.

[0003] Traditional cabinet doors have many shortcomings in structural design and installation. Regarding profile splicing, traditional methods typically require cutting the joint between two profiles at a 45° angle and then fixing them with corner brackets. This method is not only complex and requires high precision, but also consumes a significant amount of labor time and effort, increasing labor costs and making it difficult to meet the demands for rapid installation.

[0004] Regarding handle installation, traditional cabinet doors often require pre-drilled screw holes on the finished door panel. This method not only increases the number of installation steps, making the process cumbersome, but the pre-drilled screw holes may also affect the overall aesthetics of the cabinet door. Furthermore, the traditional handle installation method also has certain vulnerabilities in terms of stability, potentially leading to loosening or other problems during long-term use.

[0005] In terms of profile versatility, traditional cabinet door profiles are relatively simple in design, typically only compatible with specific types of boards (such as wood or glass), making flexible combinations impossible. This necessitates preparing a variety of different profiles during production, increasing the difficulty and cost of production management and hindering diversified product manufacturing.

[0006] In conclusion, traditional cabinet doors have significant shortcomings in terms of profile splicing, handle installation, and profile versatility, making it difficult to meet the demands of modern furniture manufacturing for efficiency, convenience, aesthetics, and low cost. Therefore, there is an urgent need for a universal cabinet door with integrated handles that can solve these problems, enabling rapid profile splicing and installation, integrated handle design, and universal profile matching. This would reduce labor costs, improve installation efficiency, and enhance the aesthetics and sturdiness of the cabinet door. Utility Model Content

[0007] The present invention aims to solve the following problems in the prior art: the splicing of profiles requires cutting the splice at a 45° angle and fixing it with corner brackets, which is a complex process with high labor costs and makes it difficult to meet the needs of rapid installation. Traditional cabinet door handles require pre-drilled screw holes, which increases the installation steps, affects the aesthetics, and is not sturdy enough. Furthermore, the profiles have poor versatility and cannot be flexibly matched with different board materials.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A universal cabinet door with integrated handle, comprising:

[0010] A general-purpose profile, used for installation with wood panels or glass, has a horizontally arranged channel A on its inner side;

[0011] The integrated handle profile is symmetrically arranged above and below the general-purpose profile. The integrated handle profile has an integrally formed handle position, and the inner side of the integrated handle profile has a horizontally arranged channel B.

[0012] The door frame aluminum profile has two sets of profiles arranged symmetrically on the left and right sides and located on both sides of the general profile and the handle integrated profile. The door frame aluminum profile has a vertically arranged channel C on the inner side.

[0013] The plug connector is used to seal and connect general profiles and door frame aluminum profiles. One end of the plug connector is sealed and inserted into channel A, and the other end is sealed and inserted into channel C.

[0014] The irregularly shaped plug is used to seal the integrated handle profile and the aluminum profile of the door frame. One end of the irregularly shaped plug is sealed and inserted into channel B, and the other end is sealed and inserted into channel C.

[0015] As a preferred embodiment, the channel A on the general-purpose profile includes an upper channel A and a lower channel A;

[0016] The plug connector is equipped with an upper locking block A that engages with the upper channel A for sealing and locking, and a lower locking block A that engages with the lower channel A for sealing and locking.

[0017] Preferably, the plug connector is provided with a locking block C for sealing and engaging with the mating channel C.

[0018] Preferably, the profile between the upper channel A and the lower channel A is provided with a screw mounting groove A, and the plug connector is provided with a screw mounting hole A. The plug connector is fixed to the general profile by a screw that passes through the screw mounting hole A and is screwed into the screw mounting groove A.

[0019] The clip C has a screw mounting hole B. The clip C is fixed to the aluminum profile of the door frame by a screw that passes through the aluminum profile of the door frame and is screwed into the screw mounting hole B.

[0020] Preferably, the irregularly shaped plug is provided with a locking block B that is sealed and engaged with the mating channel B, and a locking block D that is sealed and engaged with the mating channel C.

[0021] As a preferred embodiment, the channel B on the integrated handle profile is provided with a screw mounting groove B, and the irregular plug is provided with a screw mounting hole C. The irregular plug is fixed to the integrated handle profile by a screw that passes through the screw mounting hole C and is screwed into the screw mounting groove B.

[0022] The card block D is provided with screw mounting holes D. The card block D is fixed to the aluminum profile of the door frame by screws that pass through the aluminum profile of the door frame and are screwed into the screw mounting holes D.

[0023] Compared with the prior art, the technical effects and advantages of this utility model are:

[0024] This universal integrated handle cabinet door breaks down the door into five modules, including a universal profile and an integrated handle profile. Each module is manufactured independently and then assembled using snap-fit ​​and screws, eliminating the need for traditional 45° angle cutting and corner bracket splicing. This shortens installation time and significantly lowers the technical barrier. The universal profile is compatible with wood or glass, and the use of a single profile design reduces the variety of profiles, lowers inventory and management costs, and allows for flexible material combinations.

[0025] The integrated handle profile features a one-piece molded handle area, eliminating the need for pre-drilled screw holes in finished cabinet doors. This removes cosmetic imperfections and creates a unified load-bearing structure between the handle and the profile, capable of withstanding a 50kg vertical pull, thus enhancing stability. Horizontal channels A, B, and C form a "T-shaped" interlocking network, which, combined with the sealing interlocking of end caps and irregularly shaped end caps, improves dust and water resistance compared to traditional methods, effectively preventing dust and moisture intrusion.

[0026] The plug connector utilizes a double-locking mechanism between the upper locking block A, the lower locking block A, and channel A, combined with the screw connection between the screw mounting slot A and the screw hole A, to increase the connection strength between the general-purpose profile and the aluminum profile of the door frame by 30%. The screw fixing of locking block C and channel C forms a triangular force-bearing structure, which is especially suitable for large-size cabinet doors, reducing sagging problems caused by large spans. The balanced mechanical distribution of the vertical locking mechanism improves the ability to withstand lateral / longitudinal tensile forces, making it less prone to cracking over long-term use.

Detailed Implementation

[0038] 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.

[0039] The following combination Figures 1 to 10 This application will be described in further detail.

[0040] This application discloses a universal integrated handle cabinet door, including a universal profile 1, an integrated handle profile 2, a door frame aluminum profile 3, a plug connector 4, and a special-shaped plug 5. The universal profile 1 is used to install with wood or glass. The integrated handle profile 2 is symmetrically arranged vertically with the universal profile 1. The door frame aluminum profile 3 has two sets that are symmetrically arranged horizontally and located on both sides of the universal profile 1 and the integrated handle profile 2. The plug connector 4 is used to seal the connection between the universal profile 1 and the door frame aluminum profile 3. The special-shaped plug 5 is used to seal the connection between the integrated handle profile 2 and the door frame aluminum profile 3. The integrated handle profile 2 has an integrally formed handle position 201.

[0041] The cabinet door is divided into five modules: general profile 1, integrated handle profile 2, door frame aluminum profile 3, end cap connector 4, and irregular end cap 5. Each module can be processed and produced independently. During on-site installation, assembly can be completed by snap-fitting and fixing with screws, which greatly reduces the complex processes such as cutting and corner bracket fixing required by traditional splicing, lowers the technical threshold for installation, and shortens the installation time.

[0042] The handle position 201 is directly formed on the integrated handle profile 2, eliminating the need to pre-drill screw holes on the finished cabinet door for handle installation, thus avoiding exposed screw holes that affect aesthetics; at the same time, the integrated structure makes the handle and the profile form a whole, resulting in more even stress distribution, making it less prone to loosening over long-term use and improving the handle's sturdiness.

[0043] The general-purpose profile 1 can be installed with wood or glass. By using the same profile design, different materials can be flexibly combined, reducing the types of profiles required in the production process, reducing raw material inventory costs and production management difficulties, and facilitating diversified product production.

[0044] The general-purpose profile 1 has a horizontally arranged channel A on its inner side; the integrated handle profile 2 has a horizontally arranged channel B202 on its inner side; the door frame aluminum profile 3 has a vertically arranged channel C301 on its inner side; one end of the plug connector 4 is sealed and inserted into channel A, and the other end is sealed and inserted into channel C301; one end of the irregular plug 5 is sealed and inserted into channel B202, and the other end is sealed and inserted into channel C301.

[0045] The channel A of the general profile 1, the channel B202 of the handle integrated profile 2, and the channel C301 of the door frame aluminum profile 3 form a horizontal and vertical snap-fit ​​channel network. The plug connector 4 and the irregular plug 5 are embedded into the corresponding channels through the end blocks to form a "T" snap-fit ​​structure, which effectively prevents dust and moisture from entering the cabinet and improves the sealing of the cabinet door.

[0046] The vertical interlocking method of the horizontal and vertical channels makes the connection force distribution between the profiles more balanced. Compared with the traditional 45° angle splicing, it can withstand greater horizontal and vertical tension, reduce the problem of cracking at the splice due to uneven force, and enhance the overall structural stability of the cabinet door.

[0047] The channel dimensions of each profile are standardized and matched with the end cap size. During installation, simply align the end cap with the channel and insert it to complete the initial positioning. No on-site measurement or cutting is required, reducing the installation error rate and achieving "plug and play", which greatly improves installation efficiency.

[0048] Specifically, channel A includes an upper channel A101 and a lower channel A102. The plug connector 4 is provided with an upper locking block A401 that seals and engages with the upper channel A101 and a lower locking block A402 that seals and engages with the lower channel A102. The plug connector 4 is provided with a locking block C403 that seals and engages with channel C301. The profile between the upper channel A101 and the lower channel A102 is provided with a screw mounting groove A103. The plug connector 4 is provided with a screw mounting hole A404. The plug connector 4 is fixed to the general profile 1 by a screw that passes through the screw mounting hole A404 and is screwed into the screw mounting groove A103. The locking block C403 is provided with a screw mounting hole B405. The locking block C403 is fixed to the door frame aluminum profile 3 by a screw that passes through the door frame aluminum profile 3 and is screwed into the screw mounting hole B405.

[0049] The upper locking block A401 and the lower locking block A402 of the plug connector 4 are respectively embedded into the upper channel A101 and the lower channel A102 to form a double locking connection. Compared with the single locking block structure, it can withstand greater vertical tensile force and prevent the plug from falling off the general profile 1.

[0050] The screws are screwed into the screw mounting holes A404 and screw mounting slots A103 to further fix the plug connector 4 to the general profile 1. The dual connection method of snap-fit ​​and screw fixation improves the connection strength between the general profile 1 and the door frame aluminum profile 3, ensuring that the cabinet door will not loosen due to frequent opening and closing during long-term use.

[0051] After the card block C403 is embedded in the channel C301, it is screwed to the aluminum profile 3 of the door frame through the screw mounting hole B405, fixing the plug connector 4 to the aluminum profile 3 of the door frame as one unit. This makes the general profile 1, the plug connector 4 and the aluminum profile 3 of the door frame form a stable triangular force-bearing structure, which enhances the deformation resistance of the cabinet door side. It is especially suitable for large-size cabinet doors and can reduce the sagging problem caused by the large span of the profile.

[0052] Specifically, the irregular plug 5 is provided with a locking block B501 that seals and engages with the matching channel B202, and a locking block D502 that seals and engages with the matching channel C301. The channel B202 on the integrated handle profile 2 is provided with a screw mounting groove B203, and the irregular plug 5 is provided with a screw mounting hole C503. The irregular plug 5 is fixed to the integrated handle profile 2 by a screw that passes through the screw mounting hole C503 and is screwed into the screw mounting groove B203. The locking block D502 is provided with a screw mounting hole D504. The locking block D502 is fixed together with the door frame aluminum profile 3 by a screw that passes through the door frame aluminum profile 3 and is screwed into the screw mounting hole D504.

[0053] The locking block B501 of the irregular plug 5 is embedded in the channel B202, and the locking block D502 is embedded in the channel C301, forming a two-way locking connection. It can simultaneously withstand the force of the handle integrated profile 2 in the horizontal and vertical directions, and avoid the loosening of the profile connection due to frequent pulling during the use of the handle.

[0054] The screws are screwed into the screw mounting holes C503 and the screw mounting slots B203 to fix the irregular plug 5 to the handle integrated profile 2. Combined with the snap-fit ​​structure, the connection between the handle integrated profile 2 and the door frame aluminum profile 3 is more secure. After testing, the structure can withstand a vertical pull of about 50kg without falling off, which meets the needs of daily use.

[0055] The screw connections of the irregular plug 5, the integrated handle profile 2, and the aluminum profile of the door frame 3 are all located inside the profile or inside the plug. The screw holes cannot be seen from the outside of the cabinet door, avoiding the impact of traditional exposed screws on the appearance of the cabinet door, making the surface of the cabinet door cleaner and more beautiful, meeting the high requirements of modern home furnishing for aesthetics.

[0056] This universal handle-integrated cabinet door utilizes a modular design to enable collaborative operation of its components. The universal profile 1 and the handle-integrated profile 2 form a "T-shaped" interlocking network via horizontal channels A and B202 and the vertical channel C301 of the door frame aluminum profile 3. The plug connector 4 and the locking blocks of the irregularly shaped plug 5 are embedded into their corresponding channels for initial positioning. Then, the profiles and plugs are fixed as a whole by screwing together the screw mounting slots and screw holes. The handle position 201 on the handle-integrated profile 2 is integrally formed with the profile, and the force is transmitted to the door frame aluminum profile 3 through the locking block structure, forming a stable mechanical transmission path and ensuring the overall structural sealing and strength.

[0057] Compared to traditional cabinet doors that require cutting 45° angles and using corner brackets for assembly, this design uses a standardized snap-fit ​​and screw-fixing method, eliminating the need for complex cutting processes. Installation only requires "snap-fit ​​and screw fixing," shortening installation time and reducing the technical requirements for installers. The integrated handle design avoids the drawbacks of traditional pre-drilled screw holes, eliminating the aesthetic defects of exposed screw holes, and improving the load-bearing capacity of the handle through the overall structure, making it less prone to loosening over long-term use.

[0058] The universal profile 1 is compatible with various board materials such as wood and glass, breaking the limitations of traditional profiles that are only compatible with a single material. This reduces the types of profiles required for production, lowers raw material inventory costs, and reduces production management complexity. The standardized design of the channels and interlocking blocks forms a sealed interlocking structure. Compared with traditional splicing methods, this improves dust and water resistance. At the same time, the more balanced mechanical distribution of the vertical interlocking improves the ability to withstand lateral / longitudinal tensile forces, making it especially suitable for large cabinet doors, reducing deformation and sagging problems, and combining functional and economic advantages.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
