Description

Technical Field

[0001] This utility model relates to the field of column structure technology, and more specifically, to a four-door concealed column structure. Background Technology

[0002] A four-panel gate is a type of door consisting of four panels, commonly found as entrance doors or courtyard gates in high-end residences such as villas and courtyards. Four-panel gates can be made from various materials, such as zinc alloy, aluminum alloy, stainless steel, and copper. These materials have different characteristics and advantages, such as corrosion resistance, high strength, and aesthetic appeal.

[0003] Currently, the market commonly offers four-door doors with fixed pillars. Besides affecting the aesthetics, this also reduces the entrance size and limits the opening angle, making it difficult to load large items and defeating the purpose of maximizing the doorway. If the four-door doors don't have pillars, the hinges can't withstand the load, and the door panels are prone to sagging over time. Based on industry conditions and customer feedback, we've implemented a series of process adjustments, both in terms of technology and appearance, to create the Fuxi Hidden Pillar. This fundamentally solves the problems of unsightly four-door doors with pillars, limited entrance size, and restricted opening angles, while simultaneously enhancing functionality. Therefore, we propose a four-door concealed pillar structure. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a four-door hidden column structure to solve the technical problems of the current four-door doors with columns having an unsightly appearance, limited door size, easy damage to the hinge structure without columns, easy sagging of the door leaf, and short service life.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a four-door concealed column structure, including a side door, a middle door, and a buffer component. Two side doors and two middle doors are provided. A side groove is provided on the side of the side door connected to the middle door, and a column is installed in the side groove. Assembly slots are provided at equal intervals on the column, and an internal box is fixed in each assembly slot. Fixing components are installed at equal intervals on the inner side of the middle door, and the fixing components are rotatably installed on the internal box of the corresponding side door via a second hinge. A pressure strip is fixed on the inner side of the fixing component. The side door and the middle door form a four-door structure, and the four-door structure is rotatably installed within the door frame via a first hinge.

[0006] In use, the column is installed in the side groove, and the middle door is rotatably mounted on the inner box of the column via a second hinge. The column is hidden by the side groove, which increases the aesthetics of the outside. At the same time, the four openings increase the opening range. The rotational connection is completed through the column, avoiding the problem of short service life of simple hinge structures. When the middle door is closed, the inner pressure strip of the middle door presses the pressure end of the buffer, causing the buffer to deflect through the sleeve end. During the deflection of the buffer, the torsion spring rotates to increase the resistance, thus completing the impact buffer when the middle door closes. Existing buffers are generally completed by rubber gaskets. This type of buffer structure ages faster due to external sun exposure, rain and wind during long-term use, so it needs to be replaced regularly. The deflection buffer is completed by a strong torsion spring structure, reducing the impact when the door closes.

[0007] Preferably, an installation strip is fixed to the front side of the column, and the installation strip is fixed to the side groove of the side door by bolts.

[0008] Preferably, a central column is fixed in the middle of the interior of the built-in box, and a torsion spring is sleeved in the middle of the central column, and a through groove is provided in the middle of the outer side of the built-in box.

[0009] Preferably, the buffer has a pressure-receiving end and a sleeve end, and the sleeve end is rotatably sleeved on the central column.

[0010] Preferably, one end of the torsion spring is fixed to the inner wall of the built-in box, and the other end is connected to the turning side of the buffer.

[0011] Preferably, the pressure-bearing end of the buffer passes through the through groove and then connects to the pressure strip, and the pressure-bearing end is adapted to the inclined surface of the pressure strip.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model designs a column body, which is installed in the side groove. The middle door is rotatably installed on the built-in box of the column body through the second hinge. The column body is hidden through the side groove, which increases the aesthetics of the outside. At the same time, the four openings increase the opening range of the door. The rotation connection is completed through the column body, which avoids the problem of short service life of simple hinge structure.

[0014] 2. This utility model also incorporates a built-in box design. When the middle door closes, the inner pressure strip of the middle door presses against the pressure end of the buffer component, causing the buffer component to deflect through the sleeve end. During the deflection of the buffer component, the torsion spring rotates, increasing resistance and completing the impact buffering when the middle door closes. Existing buffering is generally achieved through rubber gaskets. This type of buffering structure ages faster due to external sun exposure, rain, and wind during long-term use, and therefore needs to be replaced regularly. The deflection buffering is achieved through a strong torsion spring structure, reducing the impact of closing the door. Attached Figure Description

Detailed Implementation

[0022] like Figures 1 to 4 As shown, this utility model relates to a four-door concealed column structure, including a side door 3, a middle door 4, and a buffer 702. There are two side doors 3 and two middle doors 4. A side groove 301 is opened on the side of the side door 3 connected to the middle door 4, and a column 5 is installed in the side groove 301. An assembly groove 501 is opened at equal intervals on the column 5, and an inner box 7 is fixed in the assembly groove 501. An installation strip 502 is fixed on the front side of the column 5, and the installation strip 502 is fixed in the side groove 301 of the side door 3 by bolts. A central column 701 is fixed in the middle of the inner box 7, and a torsion spring 704 is sleeved in the middle of the central column 701. A through groove 703 is opened in the middle of the outer side of the inner box 7.

[0023] like Figures 2 to 6As shown, this utility model relates to a four-door concealed pillar structure, including a side door 3, a middle door 4, and a buffer member 702. Fixing members 6 are equidistantly installed on the inner side of the middle door 4, and the fixing members 6 are rotatably mounted on the corresponding inner box 7 of the side door 3 via a second hinge 601. A pressure strip 602 is fixed on the inner side of the fixing member 6. The buffer member 702 has a pressure-bearing end 705 and a sleeve end 706, and the sleeve end 706 is rotatably sleeved on the middle pillar 701. One end of a torsion spring 704 is fixed... On the inner wall of the built-in box 7, the other end is connected to the turning side of the buffer 702. The pressure end 705 of the buffer 702 passes through the through groove 703 and connects to the pressure strip 602. The pressure end 705 is adapted to the inclined surface of the pressure strip 602. During the closing of the middle door 4, the pressure strip 602 squeezes the pressure end 705 to deflect the buffer 702. Then, the impact force is reduced by the resistance of the torsion spring 704. The side door 3 and the middle door 4 form a four-door, and the four-door is rotated and installed in the door frame 1 through the first hinge 2.

[0024] Working principle: This embodiment provides a four-door concealed column structure. In use, the column body 5 is installed in the side groove 301, and the middle door 4 is rotatably installed on the inner box 7 of the column body 5 through the second hinge 601. When the middle door 4 is opened, the second hinge 601 drives the inner box 7 to open. When the middle door 4 is closed, the inner pressure strip 602 of the middle door 4 presses the pressure end 705 of the buffer 702, causing the buffer 702 to deflect through the sleeve end 706. During the deflection of the buffer 702, the torsion spring 704 rotates to increase the resistance, thus completing the impact buffer when the middle door 4 is closed. The strong torsion spring 704 structure completes the deflection buffer, reducing the impact of closing the door.
