Description

Technical Field

[0001] This utility model belongs to the technical field of hinge doors, and specifically relates to a shaft-pushing hinge door opening mechanism. Background Art

[0002] At present, the push-rod type hinge door opening mechanism is widely used in the door control system. It realizes the automatic opening and closing of the door through the push-rod transmission mechanical structure.

[0003] However, due to the limitation of the push-rod transmission mechanism, when the door leaf is manually pushed by the user, the door leaf cannot be pushed due to the limitation of the push-rod transmission mechanism. The user needs to manually contact the push-rod transmission mechanism to release the limitation on the door leaf before being able to complete the manual door pushing, which is rather troublesome and brings inconvenience to the user. Content of the Utility Model

[0004] The purpose of this utility model is to provide a shaft-pushing hinge door opening mechanism, which can automatically complete the switching between the manual door pushing mode and the electric door pushing mode without manual mode selection when the user chooses, thus facilitating the use of the user.

[0005] The technical solution adopted by this utility model is specifically as follows:

[0006] A shaft-pushing hinge door opening mechanism includes a door frame and a shaft rod rotatably connected to the door frame. A door leaf is fixedly connected to the shaft rod. A turntable is fixedly connected to the upper end of the shaft rod. A first connecting round button is fixedly connected to the turntable. A limiting plate is fixedly connected to the upper side of the door frame. A fan-shaped movable area is opened on the limiting plate. The first connecting round button is located inside the fan-shaped movable area.

[0007] A linear movement unit is assembled on the upper part of the door frame. A connecting push rod is installed on the linear movement unit through a connecting unit. The first connecting round button is rotatably connected to the end of the connecting push rod far away from the connecting unit.

[0008] A force monitoring device is assembled on the connecting push rod. The force monitoring device, the linear movement unit and the connecting unit are electrically connected. The connecting unit includes an active state and a locked state.

[0009] When the force monitoring device receives a force less than the set pulling force when the linear movement unit is not started, the connecting unit is in the locked state, and the distance between the connection part of the linear movement unit and the connecting unit and the end of the connecting push rod far away from the first connecting round button is not adjustable.

[0010] When the force monitoring device receives a force greater than the set force when the linear movement unit is not started, the connecting unit is in the active state, and the distance between the connection part of the linear movement unit and the connecting unit and the end of the connecting push rod far away from the first connecting round button is adjustable.

[0011] Further, the linear movement unit includes a bracket body fixedly connected to the door frame. A drive motor is fixedly connected to the bracket body. The output end of the drive motor is fixedly connected to a screw rod. A carriage slidably connected to the bracket body is threadedly connected to the outer side of the screw rod. The carriage is fixedly connected to the connection unit.

[0012] Further, the connection unit includes an orbital body fixedly connected to the carriage. A sliding cavity is formed inside the orbital body. A notch is provided on the upper side of the sliding cavity. A sliding bracket is slidably connected inside the notch, and the sliding bracket can be locked inside the sliding cavity. A second connection knob is fixedly connected to the sliding bracket. The second connection knob is rotatably connected to one end of the connection push rod away from the first connection knob.

[0013] Further, infrared rangefinders are assembled at both ends inside the orbital body.

[0014] Further, the sliding bracket is an electromagnet. After the electromagnet is energized, it magnetically attracts the inner wall of the sliding cavity.

[0015] Further, the net height of the sliding cavity is higher than the height of the sliding bracket. An anti-slip magnetic strip is fixedly connected to the top end inside the sliding cavity. The sliding cavity magnetically attracts the energized sliding bracket through the anti-slip magnetic strip.

[0016] The technical effects achieved by this utility model are as follows:

[0017] An axial-pushing hinge door opening mechanism of this utility model can automatically adjust the state of the connection unit when the door leaf is pushed forcefully by setting a force monitoring device, and can automatically complete the switching without manual mode selection when the user selects the manual door-pushing mode and the electric door-pushing mode, which is convenient for the user to use.

[0024] In order to make the purpose and advantages of the present utility clearer, the present utility will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility, and does not strictly limit the scope of protection specifically claimed by the present utility.

[0025] As Figure 1-2 shown, a shaft-pushing hinge door opening mechanism includes a door frame 1 and a shaft rod 18 rotatably connected to the door frame 1. A door leaf 2 is fixedly connected to the shaft rod 18. When the shaft rod 18 rotates, the door leaf 2 can be driven to rotate. A turntable 19 is fixedly connected to the upper end of the shaft rod 18, and a first connecting round button 3 is fixedly connected to the turntable 19;

[0026] The upper part of the door frame 1 is equipped with a linear moving unit 6. A connecting push rod 4 is installed on the linear moving unit 6 through a connecting unit 7. The first connecting round button 3 and the end of the connecting push rod 4 away from the connecting unit 7 are rotatably connected. When the linear moving unit 6 is started, it can drive the connecting unit 7 to perform linear movement. When the connecting unit 7 moves, it will drive the first connecting round button 3 to perform revolution through the connecting push rod 4. When the first connecting round button 3 rotates, it will drive the door leaf 2 to rotate through the shaft rod 18 and the turntable 19 to open or close the door leaf 2;

[0027] Moreover, in order to limit the movement range of the first connecting round button 3, a limiting plate 22 is fixedly connected to the upper side of the door frame 1. A sector activity area 23 is opened on the limiting plate 22. The first connecting round button 3 is located inside the sector activity area 23, and the first connecting round button 3 can be limited by the sector activity area 23.

[0028] The core of this technical solution lies in that a force monitor 5 is assembled on the connecting push rod 4 to detect the force received by the connecting push rod 4. The force monitor 5, the linear moving unit 6 and the connecting unit 7 are electrically connected. The connecting unit 7 includes an active state and a locked state;

[0029] When the force monitoring device 5 is subjected to a force less than the set pulling force when the linear moving unit 6 is not activated, the connecting unit 7 is in a locked state, and the distance between the connection between the linear moving unit 6 and the connecting unit 7 and the end of the connecting push rod 4 away from the first connecting knob 3 is not adjustable, so that the rotation of the door leaf 2 is restricted by the linear moving unit 6 and can only drive the door leaf 2 to rotate when the linear moving unit 6 operates;

[0030] When the force monitoring device 5 is subjected to a force greater than the set force when the linear moving unit 6 is not activated, the connecting unit 7 is in an active state. At this time, the distance between the connection between the linear moving unit 6 and the connecting unit 7 and the end of the connecting push rod 4 away from the first connecting knob 3 is adjustable, so that the rotation of the door leaf 2 is not restricted by the linear moving unit 6 and can be manually pushed freely;

[0031] Here, the set force is set according to user requirements.

[0032] Among them, as Figure 1-2 shown, the linear moving unit 6 includes a bracket body 15 fixedly connected to the door frame 1. A transmission motor 8 is fixedly connected to the bracket body 15. The output end of the transmission motor 8 is fixedly connected to a screw rod 9. A carriage 10 slidably connected to the bracket body 15 is threadedly connected to the outside of the screw rod 9. When the transmission motor 8 is started, it can drive the screw rod 9 to rotate. When the screw rod 9 rotates, it will drive the carriage 10 to move linearly. The carriage 10 is fixedly connected to the connecting unit 7, and the position of the carriage 10 is the connection between the linear moving unit 6 and the connecting unit 7.

[0033] As Figure 1-3 shown, the connecting unit 7 includes an orbital body 11 fixedly connected to the carriage 10. A sliding cavity 21 is formed inside the orbital body 11. A notch 20 is provided on the upper side of the sliding cavity 21. A sliding bracket 12 is slidably connected inside the notch 20, and the sliding bracket 12 can be locked inside the sliding cavity 21. A second connecting knob 13 is fixedly connected to the sliding bracket 12. The second connecting knob 13 is rotatably connected to the end of the connecting push rod 4 away from the first connecting knob 3. When the sliding bracket 12 is in the unlocked state, when the door leaf 2 rotates, it will drive the sliding bracket 12 to slide through the connecting push rod 4, adjust the position of the sliding bracket 12 inside the orbital body 11, and eliminate the influence of the rotation of the connecting push rod 4 on the carriage 10 by the change of the position of the sliding bracket 12 inside the orbital body 11, thereby reducing the phenomenon of accidental locking when pushing the door.

[0034] Moreover, infrared rangefinders 14 are installed at both ends inside the track body 11. The infrared rangefinders 14 can detect the position of the sliding bracket 12. After the infrared rangefinders 14 detect a change in the position of the sliding bracket 12, they will adjust the position of the track body 11 by starting the drive motor 8 after a set time of, for example, 1 minute, so that the sliding bracket 12 can be reset to the middle position of the track body 11 again, which can reduce the fault phenomenon that occurs when the drive motor 8 drives the door leaf 2 to move.

[0035] Among them, the sliding bracket 12 is preferably an electromagnet. After the electromagnet is energized, it is magnetically attracted to the inner wall of the sliding cavity 21 to complete the locking.

[0036] At the same time, in order to further improve the stability of the sliding bracket 12 after locking, the net height of the sliding cavity 21 is higher than the height of the sliding bracket 12, and an anti-slip magnetic strip 16 is fixedly connected to the top end inside the sliding cavity 21. The sliding cavity 21 is magnetically attracted to the energized sliding bracket 12 through the anti-slip magnetic strip 16. When the sliding bracket 12 is energized, it will automatically rise until the sliding bracket 12 abuts against the anti-slip magnetic strip 16. An anti-slip strip 17 is fixedly connected to the upper side of the sliding bracket 12. When the anti-slip magnetic strip 16 abuts against the anti-slip strip 17, the locking can be completed.

[0037] The working principle of this utility model is as follows: when in use, the drive motor 8 can be started to drive the sliding frame 10 to move. When the sliding frame 10 moves, it will drive the first connecting knob 3 to revolve through the connecting unit 7 and the connecting push rod 4. When the first connecting knob 3 rotates, it will drive the door leaf 2 to rotate through the shaft rod 18 and the turntable 19 to open or close the door leaf 2.

[0038] When the user manually drives the door leaf 2 to rotate, the door leaf 2 will drive the connecting push rod 4 to apply a thrust or a pull force to the force monitor 5 through the rotation of the shaft rod 18. When the force monitor 5 detects that the force monitor 5 is subjected to a force greater than the set force, the connecting unit 7 is in an active state. At this time, the distance between the connection points of the linear movement unit 6 and the connecting unit 7 and the end of the connecting push rod 4 away from the first connecting knob 3 is adjustable, so that the rotation of the door leaf 2 is not restricted by the linear movement unit 6 and can be freely pushed manually.

[0039] In summary, by setting the force monitor 5 in this technical solution to automatically adjust the state of the connecting unit 7 when the door leaf 2 is pushed by force, it is possible to automatically complete the switching between the manual door-pushing mode and the electric door-pushing mode without manual mode selection when the user selects the manual door-pushing mode and the electric door-pushing, which is convenient for the user to use.

[0040] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. Structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special description and limitation.
