Abstract
The invention discloses a damping device applied for a manual revolving door. The manual revolving door comprises a first centre shaft and a revolving wing. The damping device comprises a transmissionpart and a damper, and the transmission part is respectively connected with the first centre shaft and the damper. When the revolving wing is subjected to external force to drive the first centre shaft to revolve together, the transmission part transmits dynamic force generated by revolution of the first centre shaft to the damper, and the damper generates resisting force opposite to the revolving direction of the first center shaft. The invention can be applied to restrict operation randomness of the manual revolving door, thereby overcoming various drawbacks which exist in the prior manualrevolving doors.
Description
Technical field
The present invention relates to the revolving door technical field, particularly be applied to the damping unit of manual revolving door.
Background technology
Fig. 1 is the vertical view of a kind of manual revolving door in the prior art, comprising: the rotation wing 11, central axis 12 and outer wall 13, and wherein rotate the wing 11 and in axial direction be fixed on the central axis 12, perhaps be integrated with central axis 12.This manual revolving door does not make consumer, and as people during to the rotation wing 11 applied thrust F, the rotation wing 11 and central axis 12 will be along the camber line arrows among Fig. 1, rotate together with rotation speed n.This manual revolving door is simple and reliable for structure and compare safety, thereby has obtained using widely.
Because manual revolving door shown in Figure 1 does not make consumer, the rotation of the rotation wing 11 will be decided by people's the thrust and the situation of natural environment fully, and randomness is very strong when causing 11 rotations of the rotation wing, mainly shows the following aspects:
The first, owing to do not use motor deceleration device, and the very little thrust of rotation 11 need of the wing just can be rotated, outdoor like this natural wind will be easy to make 11 rotations of the rotation wing in suitable angle, at this moment might cause injury near the people the rotation wing 11, quicken loss simultaneously;
The second, when people's thrust is excessive, 11 rotations of the rotation wing are too fast, may cause injury near the people the rotation wing 11, and serious also can cause security incident;
Three, after the people passes through manual revolving door, owing to inertia, the rotation wing 11 can just can stop by several circles of rotation afterwards, so also can want to bring potential safety hazard by the people of manual revolving door to follow-up.
Summary of the invention
The invention provides a kind of damping unit that is applied to manual revolving door, the operation randomness that this device can the limit manual revolving door, thus overcome all drawbacks that existing manual revolving door exists.
Technical scheme of the present invention is achieved in that
A kind of damping unit that is applied to manual revolving door, described manual revolving door comprise first central axis and the rotation wing; Key is that described damping unit comprises: drive disk assembly and damper;
Described drive disk assembly is connected with described damper with described first central axis respectively;
When the described rotation wing be subjected to external force, when driving described first central axis and rotating together, the transmission of power that described drive disk assembly is produced described first central axis by rotation makes the described damper generation resistance opposite with the direction of rotation of described first central axis to described damper.
As seen, use damping unit provided by the invention, can be when the rotation wing rotation of manual revolving door, driving damper by drive disk assembly produces and the opposite resistance of rotation wing direction of rotation, thereby effectively limited the rotation of the rotation wing, promptly limited the randomness of its rotation, thus avoid because people's thrust is excessive, natural wind blow or inertia makes the rotation of the rotation wing too fast, the people is caused injury.

The specific embodiment
For making objects and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with drawings and Examples.
Manual revolving door among the present invention comprises first central axis and the rotation wing, and when to the rotation wing applied thrust, the rotation wing will drive first central axis and rotate together.
The damping unit that is applied to manual revolving door provided by the invention comprises drive disk assembly and damper, and wherein drive disk assembly is connected with damper with first central axis respectively.When the rotation wing is subjected to external force and drives first central axis and rotate together, the transmission of power that described drive disk assembly is produced the rotation of first central axis to damper, make the damper generation resistance opposite with the direction of rotation of first central axis.As seen, use damping unit provided by the invention, can be when the rotation wing rotation of manual revolving door, driving damper by drive disk assembly produces and the opposite resistance of rotation wing direction of rotation, thereby effectively limited the rotation of the rotation wing, promptly limited the randomness of its rotation, thus avoid because people's thrust is excessive, natural wind blow or inertia makes the rotation of the rotation wing too fast, the people is caused injury.
Based on two kinds of different installation of damper, provide two embodiment of the present invention below.
