Description

Technical Field

[0001] This application relates to the field of door support technology, and in particular to a door support structure. Background Technology

[0002] Doors are the essential passage for people to enter and exit a house. They are usually combined with metal or wooden frames, combining a sense of openness with practicality, and are widely used in residential, commercial, and office settings. Doors can be divided into types such as wooden doors, glass doors, and iron doors according to their materials.

[0003] The existing door installation includes a door frame and a door panel. The door panel is hinged to the side of the door frame via metal hinges, thereby achieving a stable and flexible rotational connection between the door frame and the door panel, ensuring smooth opening and closing of the door panel during use.

[0004] Regarding the aforementioned technologies, the inventors believe that when installing heavy door panels, the existing door frames, which are mainly used to connect the door panels by rotation, also need to bear the load of the door panels. After long-term operation, the connection between the hinges and the door panels is prone to mechanical fatigue, resulting in door frame positioning deviation and poor support effect of the door frame for the door panels. Utility Model Content

[0005] The purpose of this application is to provide a door support structure to improve the problem of poor support effect of the door frame on the door panel.

[0006] The door support structure provided in this application adopts the following technical solution: A door support structure includes a door frame, on which a door panel is rotatably mounted; the door panel has pivots at both ends, and the door frame and door panel are connected via the pivots; a floor spring is provided at the bottom of the door frame, and the floor spring is connected to the pivots at the bottom of the door panel; a tapered roller bearing is embedded in the floor spring, and the inner wall of the inner ring of the tapered roller bearing is in contact with the pivots; and fixing plates are provided at both ends of the door panel, extending along the width direction of the door frame.

[0007] By adopting the above technical solution, top and bottom pivots are installed at the top and bottom of the door panel, and a floor spring is added at the bottom of the door frame. Tapered roller bearings are fitted on the top and bottom pivots at the bottom of the door panel. When the door panel is installed, the door panel presses against the tapered roller bearings. The rollers in the bearings, which are set at an inclination, divide the radial force into multiple components, which significantly improves the vertical load-bearing capacity of the door frame on the door panel. This effectively suppresses the sagging deformation and horizontal displacement of the door panel caused by gravity load, and improves the problem of poor support effect of the door frame on the door panel.

[0008] Optionally, the fixing plate is provided with a fixing groove for placing the door panel.

[0009] By adopting the above technical solution, the fixing plate is embedded and fixed to the door panel through the fixing groove. On the one hand, the relative position of the door panel and the door frame can be fixed by the limiting function, and on the other hand, an effective physical isolation zone can be formed between the door panel and the door frame.

[0010] Optionally, the fixing groove is provided with an elastic pad.

[0011] By adopting the above technical solution, the elastic buffer pad effectively absorbs the impact stress generated when the door panel comes into contact with the fixed plate during the rotation process through its material deformation characteristics, significantly reducing the wear and tear on the door panel edges and door frame, thereby improving the durability of the door system and extending its overall service life.

[0012] Optionally, connecting plates are provided on both sides of the door panel, and the fixing plates at both ends of the door panel are connected by the connecting plates.

[0013] By adopting the above technical solution, the connecting plates on both sides, through a linkage structure, enable the top and bottom fixing plates of the door panel to rotate synchronously during the door panel pushing process, thereby effectively extending the service life of the door panel.

[0014] Optionally, the fixing plate and the connecting plate are provided in a cavity.

[0015] By adopting the above technical solution and constructing a hollow cavity structure inside the fixed plate and connecting plate, the self-weight of the door panel can be significantly reduced, thereby reducing the vertical compressive stress applied to the top and bottom axes of the door panel and effectively improving the support stiffness and long-term load-bearing reliability of the door frame.

[0016] Optionally, the connecting plate is provided with connectors at both ends, and the fixing plate and the connecting plate are connected by the connectors.

[0017] By adopting the above technical solution, the traditional welding-type fixed connection method is replaced by a connection method using connectors. The detachable connection structure allows the fixing plate and the connecting plate to be quickly disassembled and separated during maintenance.

[0018] Optionally, the connector is provided with a plurality of plugs, which can be inserted into the fixing plate and the connecting plate.

[0019] By adopting the above technical solution, the plug on the connector is inserted into the fixing plate and the connecting plate to fix the fixing plate and the connecting plate. The plug connection replaces the threaded connection, which facilitates quick adjustment of the connection state between the fixing plate and the connecting plate.

[0020] Optionally, the bottom of the door frame is provided with a placement groove for placing the floor spring.

[0021] By adopting the above technical solution, the placement groove adapted to the floor spring enables the upper surface of the floor spring to be more precisely flush with the mounting reference surface at the bottom of the door frame, ensuring that the floor spring provides stable vertical support to the door panel while reducing the gap between the bottom of the door panel and the door frame.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Install top and bottom pivots on the top and bottom of the door panel respectively, and add a floor spring at the bottom of the door frame. The top and bottom pivots at the bottom of the door panel are fitted with tapered roller bearings. When the door panel is installed, when the door panel presses against the tapered roller bearings, the inclined rollers in the bearings will divide the radial force into multiple components, which will significantly improve the vertical load-bearing capacity of the door frame on the door panel, effectively suppress the sagging deformation and horizontal displacement of the door panel caused by gravity load, and improve the problem of poor support effect of the door frame on the door panel. 2. By constructing a hollow cavity structure inside the fixed plate and connecting plate, the self-weight of the door panel can be significantly reduced, thereby reducing the vertical compressive stress applied to the top and bottom axes of the door panel and effectively improving the support stiffness and long-term load-bearing reliability of the door frame. 3. After the plug on the connector is inserted into the fixing plate and the connecting plate, the fixing plate and the connecting plate are fixed together. The plug connection replaces the threaded connection, which makes it easier to quickly adjust the connection status of the fixing plate and the connecting plate. Attached Figure Description

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0026] A door support structure, as shown in the reference. Figure 1 and Figure 2The system includes a door frame 1 in the shape of a vertical square frame plate. A door panel 11 in the shape of a vertical plate is rotatably mounted on the door frame 1. A rectangular strip-shaped fixing plate 12 is fixedly mounted at both ends of the door panel 11 by means of inlay. The fixing plate 12 is provided with a fixing groove 13 for placing the door panel 11. The fixing plate 12 is embedded and fixed to the door panel 11 through the fixing groove 13. The fixing plate 12 is located at both ends of the door panel 11. On the one hand, it can fix the relative position of the door panel 11 and the door frame 1. On the other hand, it can isolate the door panel 11 from the door frame 1, which can significantly reduce the frequency of direct collision between the door panel 11 and the door frame 1 during the opening and closing process, thereby protecting the edge of the door panel 11 and improving the durability of the door panel 11 structure.

[0027] Reference Figure 1 and Figure 2 The fixing groove 13 is fixedly provided with a square-shaped elastic pad 14 by embedding. In this embodiment, the material of the elastic pad 14 is preferably rubber. By embedding the elastic buffer pad in the fixing groove 13, an elastic buffer interface can be built between the door panel 11 and the fixing plate 12, which can effectively reduce the mechanical vibration generated during the opening and closing of the door panel 11, thereby reducing the risk of damage to the edge of the door panel 11 caused by rigid collision and realizing the protection of the door panel 11.

[0028] Reference Figure 1 and Figure 2 The door panel 11 has cylindrical top and bottom shafts 2 at both ends. The top and bottom shafts 2 pass through the fixing plate 12 and are connected to the door frame 1. The bottom of the door frame 1 has a floor spring 21, which is connected to the top and bottom shafts 2 at the bottom of the door panel 11. When the door panel 11 is pushed, the door panel 11 rotates around the axis of the top and bottom shafts 2. The floor spring 21 and the top and bottom shafts 2 are rigidly connected to achieve locking and fixation. Its internal damping mechanism can provide a constant vertical support force to the door panel 11, effectively suppressing the sagging deformation and horizontal displacement of the door panel 11 caused by gravity load, and improving the problem of poor support effect of the door frame 1 on the door panel 11.

[0029] Reference Figure 1 and Figure 3 The floor spring 21 is fitted with a tapered roller bearing 3 by means of embedding and fixing. The inner wall of the inner ring of the tapered roller bearing 3 is in contact with the top and bottom shafts 2. The lower end of the inner ring of the tapered roller bearing 3 is a blind end, and the upper end is for the top and bottom shafts 2 to be inserted to support the top and bottom shafts 2. The tapered roller bearing 3 is embedded in the groove on the top surface of the floor spring 21. When the door panel 11 is installed, the door panel 11 exerts a radial load on the tapered roller bearing 3. The rollers arranged at an inclination inside the tapered roller bearing 3 decompose the single radial pressure into a composite force system of axial force and radial force. Through the multi-directional force co-bearing method, the vertical pressure of the door panel 11 on the door frame 1 is effectively reduced, and the problem of poor support effect of the door frame 1 on the door panel 11 is improved.

[0030] Reference Figure 1 and Figure 2 The bottom of the door frame 1 is provided with a placement groove 15 for placing the floor spring 21. Through the structural design of the placement groove 15 adapted to the floor spring 21, the upper surface of the floor spring 21 is made to be relatively precisely flush with the mounting reference surface at the bottom of the door frame 1. While ensuring that the floor spring 21 provides stable vertical support to the door panel 11, the distance between the bottom of the door panel 11 and the door frame 1 is reduced.

[0031] Reference Figure 1 and Figure 2 The door panel 11 is provided with rectangular strip-shaped connecting plates 22 on both sides. The connecting plates 22 extend along the length of the door frame 1. The fixing plates 12 at both ends of the door panel 11 are connected by the connecting plates 22. The connecting plates 22 rigidly connect the fixing plates 12 at the upper and lower ends of the door panel 11 to form a linkage mechanism. When the door panel 11 rotates around the axis of the top and bottom axis 2, the connecting plates 22 can ensure that the upper and lower fixing plates 12 rotate synchronously around the axis, thereby effectively suppressing the sway displacement of the door panel 11 during rotation and significantly improving the dynamic stability of the door panel 11 when opening and closing.

[0032] Reference Figure 1 and Figure 3 The fixing plate 12 and the connecting plate 22 are hollow. By setting a hollow cavity structure in the fixing plate 12 and the connecting plate 22, the self-weight of the door panel 11 can be significantly reduced, thereby reducing the vertical compressive stress of the door panel 11 on the top and bottom shafts 2. This lightweight design not only reduces the overall weight of the door panel 11, but also effectively improves the support stiffness of the door frame 1 on the door panel 11 and the long-term load-bearing reliability by optimizing the force transmission path.

[0033] Reference Figure 1 and Figure 3 The connecting plate 22 is provided with square-shaped connectors 23 at both ends. The fixing plate 12 and the connecting plate 22 are connected by the connectors 23. The fixing plate 12 and the connecting plate 22 adopt a detachable connection structure, which allows the fixing plate 12 and the connecting plate 22 to be quickly disassembled and separated during maintenance, significantly improving the convenience of maintenance.

[0034] Reference Figure 1 and Figure 3 The connector 23 is fixedly provided with a number of plugs 24 by welding. The plugs 24 can be inserted into the fixing plate 12 and the connecting plate 22. In this embodiment, the plugs 24 are square-shaped, and the number of plugs 24 is preferably two, which are respectively provided on two adjacent sides of the connector 23. The fixed connection with the fixing plate 12 and the connecting plate 22 is achieved by plugging. This design adopts a four-corner distributed fixing structure to replace the traditional threaded connection, that is, four connectors 23 correspond to the four corners of the door panel 11 respectively.

[0035] The implementation principle of this application embodiment is as follows: When installing the door panel 11, first, the floor spring 21 is positioned and installed at the bottom of the door frame 1. Then, the fixing plate 12 is fitted and assembled on the upper and lower ends of the door panel 11 respectively. The fixing plate 12 and the connecting plate 22 are rigidly connected by the detachable connector 23. After the pre-assembly is completed, the top and bottom shafts 2 are installed on both ends of the fixing plate 12 respectively. The bottom top and bottom shafts 2 and the floor spring 21 are connected and installed by a precision snap-fit ​​structure. After the tapered roller bearing 3 is embedded in the floor spring 21, the door panel 11 is fixed to the door frame 1 as a whole, which improves the support force of the door frame 11 on the door panel 1 and improves the problem of poor support effect of the door frame 1 on the door panel 11.

[0036] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
