Referring to
By the arrangement of the above structure, during use, the first connecting component 10 is connected to the surface of the rotating door, and it is generally connected to a position, close to the rotating shaft, on the surface of the rotating door. The second connecting component 20 is then connected to the supporting surface or mounting surface such as a door frame and a wall surface, and it is generally also connected to a position, close to the rotating shaft of the rotating door, on the supporting surface or mounting surface. Further, an adjustment device is used to drive the elastic reset member to move to increase or decrease the elastic deformation of the elastic reset member, thus adjusting an elastic force of the automatic reset device for the door independently according to a need of a user, making it convenient for the use to use the automatic reset device for the door. Moreover, damage to the rotating door caused by an extremely high resilience force can be prevented, and the influence caused by an extremely low resilience force on the reset effect of the automatic reset device for the door can also be prevented.
In this embodiment, the adjustment component 40 includes a connector 41 and an actuator 42; the actuator 42 is rotatably connected to the connector 41; the connector 41 is connected to the second connecting component 20; the actuator 42 is connected to the second end of the elastic reset member 30; and the actuator 42 drives the elastic reset member 30 to increase or decrease the elastic deformation when rotating relative to the connector 41. By the arrangement of the above structure, the connector 41 can fixedly connect the adjustment component 40 to the second connecting component 20, so that the adjustment component 40 can move synchronously with the second connecting component 20, and thus change a deformation amount of the elastic reset member when the first connecting component 10 and the second connecting component 20 rotate relative to each other, thereby changing the elastic force. When the first connecting component 10 and the second connecting component 20 are relatively stationary, the elastic reset member 30 can be directly driven to increase or decrease the elastic deformation by adjusting the actuator 42, which achieves the purpose of adjusting the magnitude of the resilience force.
In this embodiment, a first ratchet wheel part 411 is arranged on a connection surface of the connector 41 to the actuator 42, and a second ratchet wheel part 421 is arranged on a connection surface of the actuator 42 to the connector 41; and the first ratchet wheel part 411 cooperates with the second ratchet wheel part 421 to allow relative rotation between the connector 41 and the actuator 42 in a first circumferential direction and to hinder relative rotation between the connector 41 and the actuator 42 in a second circumferential direction. By the arrangement of the above structure, the connector 41 and the actuator 42 can rotate in one way relative to each other through the first ratchet wheel part 411 and the second ratchet wheel part 421. The second circumferential direction is the same as a direction of the resilience force of the elastic reset member. This setting can prevent an elastic reset force from driving the connector 41 and the actuator 42 to rotate relative to each other, so that the stability of the elastic reset force of a product is ensured, and the door can be reset stably. On the contrary, the first circumferential direction is opposite to the direction of the resilience force of the elastic reset member, that is, during the relative rotation between the connector 41 and the actuator 42 in the first circumferential direction, the deformation amount of the elastic reset member can be increased, thereby increasing the resilience force of the elastic reset member.
In this embodiment, the connector 41 is provided with a through hole 412, and the actuator 42 is provided with a coupling part 422; the coupling part 422 is arranged opposite to the through hole 412; the coupling part 422 is configured to be coupled with a working end of a twisting tool; and the through hole 412 is configured to allow the working end of the twisting tool to pass through for use. By the arrangement of the above structure, during use, the working end of the twisting tool, for example, a tool bit of a screwdriver, passes through the through hole and is coupled to the coupling part, so that the actuator can be driven to rotate by rotating the screwdriver, and the resilience force of the elastic reset member is conveniently adjusted, making it convenient for use. The coupling part can be an inner hexagon screw hole.
In this embodiment, the first connecting component 10 is provided with a first shaft hole 11 and a first rotating shaft 12; the second connecting component 20 is provided with a second shaft hole 21; at least part of the adjustment component 40 is arranged in a columnar shape to form a second rotating shaft; the second rotating shaft is rotatably inserted into the first shaft hole 11; the first rotating shaft 12 is rotatably inserted into the second shaft hole 21; and the first rotating shaft 12, the second rotating shaft, the first shaft hole 11, and the second shaft hole 21 are all coaxial to allow relative rotation between the first connecting component 10 and the second connecting component 20. By the arrangement of the above structure, during use, the first rotating shaft 12, the second rotating shaft, the first shaft hole 11, and the second shaft hole 21 are coaxial, which can ensure that the first connecting component 10 and the second connecting component 20 can rotate around the same axis, so that the first connecting component 10 and the second connecting component 20 are stably rotatably connected to each other.
In this embodiment, the elastic reset member 30 is a torsional spring; the torsional spring is inserted into the first shaft hole 11; a first clamping part 423 is arranged at a lower part of the actuator 42; a second clamping part 121 is arranged at an upper part of the first rotating shaft 12; and one end of the torsional spring is clamped to the first clamping part 423, and the other end of the torsional spring is clamped to the second clamping part 121. By the arrangement of the above structure, use of the torsional spring as the elastic reset member is more suitable for storing elastic potential energy during rotation, and the cost is low. The torsional spring is inserted into the first shaft hole 11, which can effectively limit the torsional spring when the torsional spring deforms and further ensure the stability of the product. Furthermore, the torsional spring can be effectively hidden, the aesthetics and safety of the product can be improved, and the user can be prevented from being pinched when the torsional spring deforms. Two ends of the torsional spring are respectively connected to the first clamping part 423 and the second clamping part 121, which can achieve connections between the torsional spring and the first connecting component 10, as well as between the torsional spring and the second connecting component 20, and provide a restoring force for the first connecting component 10 and the second connecting component 20. Moreover, when the user adjusts the actuator 42, the torsional spring will also deform in a vertical direction to allow the second ratchet wheel part 421 to slide along a surface of the first ratchet wheel part 411, making it convenient for the user to adjust the actuator 42.

The structure is simple, and the mounting is convenient. Preferably, a thread is arranged on an inner wall of the first through hole 111. The thread is matched with a thread at a tail end of the first limiting column 50 to stably connect the first limiting column 50 to the first through hole 111 and the insertion hole 122, so that separation of the first limiting column 50 is prevented, and the stability of the product is ensured.
