Description

Technical Field

[0001] This application relates to the field of swing doors, and more particularly to a concealed door operator. Background Technology

[0002] Currently, doors are an essential device between the interior and exterior. On the one hand, doors can protect the privacy of the interior, and on the other hand, they can protect the property inside.

[0003] Regarding the aforementioned technologies, there are still some shortcomings: existing swing door operators are generally installed on the outside of the door frame and control the rotation of the door panel through a drive rod. However, since the door operator is located on the outside, it is subject to the corrosion of dust and dirt, and dust will adhere to the drive rod, making it difficult for users to clean the door operator and drive rod. Therefore, improvements are still needed. Utility Model Content

[0004] In order to achieve the integration of the door operator and the door frame, so that the door operator can still maintain the opening and closing function of the door panel when it is embedded in the door frame, this application provides a concealed door operator.

[0005] This application provides a concealed door operator, which adopts the following technical solution:

[0006] A concealed door operator includes a door frame and a door panel. The door frame has a receiving cavity on the side facing the door panel, and a door operator for controlling the rotation of the door panel is disposed in the receiving cavity. A drive rod is connected between the door operator and the door panel. One end of the drive rod is rotatably connected to the door operator, and the other end of the drive rod is embedded in the door panel and slidably connected to the door panel. The opening of the receiving cavity faces the direction of rotation of the door panel. A fixing member can also be detachably connected to the end of the door frame facing the door panel, and the fixing member can fix the door operator.

[0007] By adopting the above technical solution, the door operator is installed inside the door frame, and then the door operator is protected by fasteners, realizing the integration of the door operator and the door frame, so that the door operator can still maintain the opening and closing function of the door panel when it is embedded in the door frame.

[0008] Optionally, the fixing component is a limiting plate, and the two ends of the limiting plate facing the door frame are slidably connected to the snap-fit ​​plates. The snap-fit ​​plates can be inserted into the door frame. A spring is also provided between the limiting plate and the snap-fit ​​plates, and the spring makes the snap-fit ​​plates always have a tendency to move towards the door frame.

[0009] By adopting the above technical solution, the snap-fit ​​plate is inserted into the door frame under the action of the spring, thereby achieving a relatively fixed connection of the limiting plate within the door frame, thus fixing the limiting plate within the door frame. The limiting plate is used to fix the door operator.

[0010] Optionally, a push-pull handle is rotatably connected to the snap-fit ​​plate. The push-pull handle can move toward the door frame. When the push-pull handle moves, it drives the snap-fit ​​plate to move synchronously.

[0011] By adopting the above technical solution, the push handle is rotated so that part of the push handle extends out of the latching plate, making it convenient for the staff to contact the push handle and pull the latching plate by gripping it. This allows the latching plate to overcome the spring force and move out of the door frame, making it convenient for the staff to remove the limiting plate from the door frame.

[0012] Optionally, the fastener is a connecting plate, with threaded holes on both sides, and bolts are rotatably connected to the threaded holes, the ends of which can be inserted into the door frame.

[0013] By adopting the above technical solution, the fastener and the connecting plate are fixedly connected by bolts. The use of bolts enhances the stability of the connection between the fastener and the door frame, strengthens the safety of the door frame in the cavity, and also facilitates the disassembly of the fastener and the door frame by the staff.

[0014] Optionally, the door frame is made of iron, and the two sides of the connecting plate with threaded holes are magnetic components that can be magnetically connected to the door frame.

[0015] By adopting the above technical solution, the magnetic connection between the magnetic component and the door frame is used to achieve the initial fixation of the door frame and the connecting plate, thereby facilitating the subsequent fixing of the connecting plate and the door frame with bolts.

[0016] Optionally, a door panel damper is also installed inside the receiving cavity, and the door panel damper is connected to the drive rod.

[0017] By adopting the above technical solution, the door panel damper reduces the noise when the door panel is pushed, keeping it relatively quiet and reducing the noise from the door panel turning, which would affect daily life.

[0018] In summary, the beneficial technical effect of this application is that by installing the door operator inside the door frame and then protecting the door operator with fasteners, the door operator and the door frame are integrated, so that the door operator can still maintain the opening and closing function of the door panel when it is embedded in the door frame.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a concealed door operator. (Refer to...) Figure 1 , Figure 2 A concealed door operator includes a door panel 2 and a door frame 1, with the door panel 2 and door frame 1 rotatably connected. The door opens and closes as the door panel 2 rotates.

[0027] Reference Figure 1 , Figure 2 A receiving cavity 3 is provided on the side of the door frame 1 facing the door panel 2, and a door operator 4 for controlling the rotation of the door panel 2 is installed in the receiving cavity 3. A drive rod 5 is also connected between the door operator 4 and the door panel 2. One end of the drive rod 5 rotates with the door operator 4, while the other end of the drive rod 5 is embedded in the door panel 2 and slidably connected to the door panel 2. The movement of the drive rod 5 controls the closing or opening of the door panel 2.

[0028] A fastener 6 can be detachably connected to the end of the door frame 1 facing the door panel 2. The fastener 6 can fix the door machine 4 and also shield the door machine 4 and other components located in the receiving cavity 3.

[0029] Reference Figure 2 , Figure 3 as well as Figure 4 The fixing component 6 is a limiting plate, and locking plates 7 are slidably connected to both ends of the limiting plate facing the door frame 1. The ends of the locking plates 7 can be inserted into the door frame 1. A spring 8 is also provided between the locking plates 7 and the limiting plate. One end of the spring 8 is fixedly connected to the locking plate 7, and the other end of the spring 8 is fixedly connected to the limiting plate. Under the action of the spring 8, the locking plates 7 always have a tendency to move away from the limiting plate.

[0030] After the user inserts the limiting plate into the bottom of the receiving cavity 3, the snap-fit ​​plate 7, under the action of the spring 8, inserts into the door frame 1, thereby achieving a relatively fixed connection of the limiting plate within the door frame 1, and fixing the limiting plate within the door frame 1. The limiting plate is used to fix the door operator 4.

[0031] Reference Figure 2 , Figure 3 as well as Figure 4 A push handle 9 is rotatably connected to the snap-fit ​​plate 7. The push handle 9 is rotatably connected to the snap-fit ​​plate 7, but as the snap-fit ​​plate 7 slides, the push handle 9 can move synchronously. When the snap-fit ​​plate 7 is inserted into the door frame 1 under the action of the spring 8, the push handle 9 will also move towards the door frame 1.

[0032] If the staff needs to remove the locking plate 7 from the door frame 1, they should first rotate the push handle 9 so that part of the push handle 9 extends out of the locking plate 7, making it easier for the staff to contact the push handle 9 and pull the locking plate 7 by gripping the push handle 9. This allows the locking plate 7 to overcome the elastic force of the spring 8 and move out of the door frame 1, making it easier for the staff to remove the limiting plate from the door frame 1.

[0033] Reference Figure 1 , Figure 2 A door panel 2 damper is installed inside the cavity 3. The door panel 2 damper is connected to the drive rod 5. The door panel 2 damper reduces the noise when the door panel 2 is pushed, keeping it relatively quiet and reducing the noise of the door panel 2 rotating, which may affect daily life.

[0034] In another embodiment, reference is made to Figure 5 The fastener 6 is a connecting plate. Threaded holes 10 are provided on both sides of the connecting plate that contact the door frame 1. Threaded holes 10 are also provided inside the door frame 1 that can align with the threaded holes 10 on the connecting plate. After the connecting plate is connected to the door frame 1, the threaded holes 10 on the door frame 1 are aligned with the threaded holes 10 on the connecting plate. Then, the operator passes bolts 11 through the threaded holes 10 on the connecting plate and screws them into the threaded holes 10 on the door frame 1, thus achieving a relatively fixed connection between the connecting plate and the door frame 1 through the fixing of the bolts 11.

[0035] The door frame 1 is made of iron, and a magnetic component 12 is connected to one end of the connecting plate with a threaded hole 10, which can be magnetically connected to the door frame 1. After the user aligns the threaded hole 10 on the connecting plate and the door frame 1, the magnetic component 12 is used to magnetically connect with the door frame 1 to achieve initial fixation of the door frame 1 and the connecting plate, thereby facilitating the subsequent fixed connection of the connecting plate and the door frame 1 with bolts 11.

[0036] This application discloses a hidden door operator implementation principle as follows: the door operator 4 is installed inside the door frame 1, and the door operator 4 is protected by the fastener 6, so that the door operator 4 and the door frame 1 are integrated, and the door operator 4 still maintains the opening and closing function of the door panel 2 when it is embedded in the door frame 1.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
