Abstract
Description
Technical Field
[0001] This utility model relates to the field of architectural door decoration, specifically to a grille door using snap-on grille strips. Background Technology
[0002] Grille doors have multiple uses, primarily including privacy protection, light regulation, ventilation, and security against theft and rain. They can be used in entryway design, providing both privacy and a warm, welcoming atmosphere. Grille doors can also serve as privacy screens, protecting privacy without blocking light. Installing grille doors in sunny locations can both block sunlight and create sophisticated light and shadow effects. However, most existing grille doors are one-piece structures, with the grille strips welded to the door frame, making disassembly difficult. If parts are damaged, partial replacement is challenging, and the grille strips easily accumulate dust, obstructing daily cleaning and maintenance. Utility Model Content
[0003] The purpose of this utility model is to provide a grille door with snap-on grille strips, which aims to solve the problems of existing grille doors where partial replacement is difficult when damaged, and where grille strips easily accumulate dust and obstruct daily cleaning of the door panel, making daily cleaning and maintenance extremely inconvenient.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A grille door with snap-on grille strips is provided, including a door frame body. The inner periphery of the door frame body is provided with a groove, and a door panel is fixedly mounted on the groove. Several grille strips are arranged at intervals on both sides of the door frame body and the door panel. Both ends of the grille strips are detachably connected to the door frame body by snap-on blocks. The snap-on blocks are fixedly connected to the door frame body. The inner wall of the grille strips is provided with limiting protrusions facing each other along the length direction. The snap-on blocks are provided with matching slots corresponding to the limiting protrusions.
[0006] Preferably, the door panel is a glass door panel.
[0007] Preferably, each corner of the card block along the length of the grille strip is chamfered, and the grille strip extends from the chamfer near the door panel with a fastening part.
[0008] Preferably, the grid strip is a hollow tube, and the opposing limiting protrusions on the inner wall of the grid strip are arc-shaped protrusions.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] This utility model provides a grille door using snap-on grille strips. By cooperating with the limiting protrusions at both ends of the grille strips with the slots of the door frame blocks, a snap-on connection structure is adopted to realize the detachable design of the grille strips. Each grille strip can be removed individually, and only the damaged part needs to be replaced, which greatly reduces maintenance costs and time. The detachable grille strips can be cleaned individually or removed as a whole, completely solving the problem of cleaning obstruction. The density or arrangement of the grille strips can be adjusted according to the needs of the scene. The snap-on structure realizes the maintainability and functional expandability of the grille door. Attached Figure Description

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.
[0020] The following is combined Figures 1 to 4 This invention describes a grille door that uses snap-on grille strips.
[0021] like Figures 1 to 4 As shown, this utility model provides a grille door using snap-on grille strips, including a door frame 1, a groove 2 is provided on the inner periphery of the door frame 1, and a door panel 3 is fixedly installed through the groove 2. The door panel 3 is a glass door panel 3. Several grille strips 4 are arranged at intervals on both sides of the door frame 1 and the two ends of the grille strips 4 are detachably connected to the door frame 1 through a snap block 5. The snap block 5 is fixedly connected to the door frame 1. The inner wall of the grille strip 4 is provided with a limiting protrusion 6 facing each other along the length direction. The snap block 5 is provided with a matching snap groove 7 corresponding to the limiting protrusion 6.
[0022] Preferably, each corner of the locking block 5 along the length of the grille strip 4 is provided with a chamfer 8. The chamfer 8 at the corner of the locking block 5 forms a beveled guide, making it easier for the limiting protrusion 6 of the grille strip 4 to slide into the slot 7, effectively improving installation efficiency. The grille strip 4 is provided with a fastening part 9 extending from the chamfer 8 near the door panel 3. The fastening part 9 extending from the grille strip 4 and the chamfer 8 of the locking block 5 form an overlapping structure. The beveled contact between the chamfer 8 and the fastening part 9 can disperse vibration energy and reduce the risk of loosening after long-term use.
[0023] Preferably, the grille strip 4 is a hollow tube, and the opposing limiting protrusions 6 on the inner wall of the grille strip 4 are arc-shaped protrusions. The arc-shaped surface reduces the frictional resistance with the locking block 5, achieving a smooth "plug-and-play" operation experience.
[0024] This utility model provides a grille door using snap-on grille strips 4. By having the limiting protrusions 6 at both ends of the grille strips 4 cooperate with the slots 7 of the door frame clips 5, a snap-on connection structure is adopted to realize the detachable design of the grille strips 4. Each grille strip 4 can be disassembled individually, and only the damaged part needs to be replaced, which greatly reduces maintenance costs and time. The detachable grille strips 4 can be cleaned individually or removed as a whole, completely solving the problem of cleaning obstruction. The density or arrangement of the grille strips 4 can be adjusted according to the needs of the scene. The snap-on structure realizes the maintainability and functional expandability of the grille door.
[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
