Description

Technical Field

[0001] The utility model relates to the technical field of aluminum frame structures, and particularly discloses a frame door structure with an angle bracket. Background Art

[0002] Frame door structures play a crucial role in architecture and home decor, with stability and durability being key design considerations. Traditional frame door construction typically consists of multiple frames, secured together using specific connections to form a stable framework. A common method is the use of corner brackets, which connect and secure two adjacent corners of the frame, thus ensuring the overall structure of the frame door.

[0003] Our company's prior patent CN202223529233.X discloses a hidden frame door compatible with multiple hinge systems. The door frame includes four frame bars assembled to form a square frame, and two adjacent frame bars are connected by an L-shaped connecting angle bracket. Among them, two screws are connected between the horizontal frame bar and the angle bracket of the door frame. This is because one screw will form a "single rotating shaft". The load-bearing gravity on the horizontal frame bar forms a torque on the screw connected to the angle bracket, which causes the horizontal frame bar to form a tendency to rotate easily around one screw. Therefore, two screws are connected to the angle bracket to prevent the horizontal frame bar from rotating around a single screw and causing the frame to loosen. For the longitudinal frame bar, it is believed that it is in the same direction as the gravity and does not generate torque. Due to structural cost considerations, the traditional setting is to connect the longitudinal frame bar and the angle bracket with only one screw.

[0004] However, in actual use of frame doors, problems such as loose connection of frame strip corner brackets still occur, so further improvements are needed to improve the connection stability and service life of the frame door structure. Utility Model Content

[0005] After long-term use, the frame door structure may have problems such as loose connections between the frame strips. After research, it was found that in fact, when the user pushes and pulls the frame door, there will be pushing and pulling forces on the longitudinal frame in various directions, including the horizontal direction. As a result, the longitudinal frame, which originally has no torque, will also form a torque during the pushing and pulling process, resulting in a "single-axis" situation on the screws connecting the angle code. Especially for aluminum frame doors equipped with top and bottom hinges, they are greatly affected by gravity during use. After long-term pushing and pulling, the longitudinal frame strips will become loose, deformed, and drooping, which will seriously affect the user experience and the overall quality of the product. The instability of this structure may also shorten the service life of the product and increase the cost of maintenance and replacement.

[0006] To solve this problem, the utility model provides a frame door structure with an angle bracket.

[0007] The utility model discloses a frame door structure with an angle bracket, which adopts the following technical solutions:

[0008] A frame door structure with a corner bracket, comprising:

[0009] Transverse frame profiles, serving as components of the frame door structure;

[0010] A longitudinal frame profile, serving as another component of the frame door structure and connected to the transverse frame profile;

[0011] The corner bracket has at least two connecting arms for respectively connecting the mutually spliced transverse frame profiles and longitudinal frame profiles, wherein each connecting arm is provided with at least two fasteners for fixing with the corresponding frame profile.

[0012] By adopting the above technical means, the longitudinal frame profile will not become loose due to the torque generated by the user pushing and pulling, which causes the "single axis" to rotate, thereby improving the overall stability and service life of the frame door structure.

[0013] Preferably, the connecting arm is divided into at least an extension section and a connecting section along the extension direction, at least one side of the connecting section is hollowed out to form a cavity, and a mounting position for connecting the fastener is provided in the cavity.

[0014] Preferably, reinforcing ribs are connected between adjacent installation positions.

[0015] Preferably, a hinge mounting groove is provided on one side of the extension section.

[0016] Preferably, the opening direction of the cavity of the connecting section is opposite to the opening direction of the hinge installation slot of the extension section.

[0017] Preferably, the fasteners on each connecting arm are arranged along the extension direction of the connecting arm.

[0018] Preferably, the transverse frame profile and the longitudinal frame profile are respectively provided with an insertion cavity for inserting the angle code, the cross-sectional size of the insertion cavity is adapted to the cross-sectional size of the angle code, the transverse frame profile and the longitudinal frame profile are respectively provided with a fixing position connected to the insertion cavity, and the fastener is connected to the installation position at the fixing position.

[0019] Preferably, the number of mounting positions on each connecting arm is greater than the number of fixing positions on the corresponding connected profile frame, and the two frame profiles are provided with openings connected to their corresponding plug-in chambers, and most of the mounting positions on the connecting arm that are paired with the fixing positions are exposed from the openings.

[0020] Preferably, the fastener is a fastening screw, and the connecting arm is provided with a threaded hole that matches the fastening screw.

[0021] Preferably, the frame door is an aluminum frame door.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] The utility model provides at least two fasteners on the two connecting arms of the corner bracket, so that the connection between the corner bracket and the horizontal frame profile, especially the vertical frame profile, is firmly connected at two points, which increases the balance of force during connection and avoids the problem of "single shaft" loosening caused by a single connection point. At the same time, it also increases the connection strength of the four frames of the frame door, which can effectively reduce the problem of sagging and loosening of the frame door.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] This embodiment discloses a frame door structure with a corner code 3, referring to Figure 1-5The frame door structure includes four frame profiles spliced together to form a square frame, and corner brackets 3 for the frame profiles. The frame profiles include two parallel transverse frame profiles 1 and two longitudinal frame profiles 2 connecting the two transverse frame profiles 1. The corner brackets 3 have two connecting arms, each used to connect the spliced transverse frame profiles 1 and longitudinal frame profiles 2, respectively. Each connecting arm is provided with at least two fasteners 4 to secure it to the corresponding frame profile. In this embodiment, the frame door is made of aluminum, and the fasteners 4 are specifically fastening screws. The connecting arms are provided with threaded holes that match the fastening screws.

[0033] By adopting the above design, the corner code 3 is not only stably connected to the horizontal frame, but also has two fastening parts with the longitudinal frame profile 2. In this way, even if there is no longitudinal frame profile 2 that forms a torque under normal circumstances, the corner code 3 can be stably connected, so that when the user pulls the longitudinal frame profile 2, no matter how much force is applied to it in various directions to form a torque, the problem of "single-axis" loosening caused by a single connection point will not occur. The double fasteners 4 on the two connecting arms of the corner code 3 not only increase the balance of force when the corner code 3 is connected to the horizontal frame profile 1 and the longitudinal frame profile 2, but also increase the connection strength of the four frames of the frame door structure, effectively reducing the problem of sagging and loosening of the frame door structure.

[0034] Specifically, see Figure 3-4 In this embodiment, the connecting arm of the corner bracket 3 is divided into at least an extension section 31 and a connecting section 32 along its extension direction. At least one side of the connecting section 32 is hollowed out to form a cavity 321. Within the cavity 321 are mounting locations 322 for the fastener 4. Preferably, reinforcing ribs 323 are connected between adjacent mounting locations 322 to enhance structural strength. By configuring the connecting section 32 of the corner bracket 3 as a hollowed-out cavity 321 with mounting locations 322, this solution replaces the traditional solid-surface structure of the corner bracket 3. This ensures the structural strength of the corner bracket 3 while reducing its own weight, further improving the connection stability of the frame door structure.

[0035] In addition, a hinge mounting groove 311 is provided on one side of the extended section 31 of the angle bracket 3, so that the hinge can be embedded in the extended section 31 of the angle bracket 3, making the frame door structure suitable for making a hidden frame door, improving the integrity and aesthetics of the frame door. Among them, the opening direction of the cavity 321 of the connecting section 32 of the angle bracket 3 and the opening direction of the hinge mounting groove 311 of the extended section 31 of the angle bracket 3 are preferably designed to be one positive and one negative, referring to Figure 5 This can help the fastener 4 to be fastened and installed more easily in the installation position 322 of the connecting section 32 of the angle bracket 3, and also help to improve the structural stability of the angle bracket 3. Of course, in other embodiments, the cavity 321 of the connecting section 32 of the angle bracket 3 can also be symmetrically opened on both sides.

[0036] In this embodiment, the fasteners 4 on each of the connecting arms are arranged along the extension direction of the connecting arm. This arrangement is the optimal layout design and can also be designed as other arrangements according to needs. In addition, the transverse frame profile 1 and the longitudinal frame profile 2 are respectively provided with a plug-in chamber 11 for the angle code 3 to be plugged in. The cross-sectional size of the plug-in chamber 11 is adapted to the cross-sectional size of the angle code 3. The transverse frame profile 1 and the longitudinal frame profile 2 are respectively provided with a fixing position 12 connected to the plug-in chamber 11. The fastener 4 is connected to the installation position 322 at the fixing position 12. The plug-in chamber 11 plays a certain limiting role on the angle code 3, which better avoids the problems of displacement, loosening, etc. of the angle code 3 and the frame profile. Furthermore, the number of installation positions 322 on each connecting arm is greater than the number of fixing positions 12 on the corresponding connected profile frame; the two frame profiles are provided with openings connected to their corresponding plug-in chambers 11, refer to Figure 1 The mounting position 322 on the connecting arm that is matched with the fixing position 12 is exposed from the opening, and the mounting position 322 exposed from the opening is used to be fixed with the hinge in the hinge mounting groove 311 by screws.

The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
