Description
Technical field
The present invention relates to revolving door security technology area more particularly to a kind of revolving door crack between a door and its frame finger pinch devices.
Background technique
Revolving door is widely used in building, since it is convenient for disengaging, so the application in public building is more common.
But revolving door in off position when, there are gaps between the door body edge and doorframe of common revolving door, for resting on a side
People or the child that nearby plays, the revolving door clamp hand being easy during being rotated damage.Especially for peace
The weaker child of full consciousness, it is easier to damage.
Summary of the invention
In order to solve the above-mentioned technical problem the present invention provides a kind of revolving door crack between a door and its frame finger pinch device, can avoid revolving door
Door body and doorframe between crack between a door and its frame clamp hand the problem of, and the finger pinch device structure is simple, at low cost.
The technical scheme to solve the above technical problems is that a kind of revolving door crack between a door and its frame finger pinch device, is mounted on
On revolving door, the revolving door includes the side doorframe being vertically arranged, rotatable door body, as the door of door body Pivot axle
Axis, the door-hinge are vertically arranged in the edge of door body and are rotatablely connected with door body.The finger pinch device includes coaxially being set in
Cylindrical protective item on door-hinge, the security bar are provided with the card slot for being fixedly connected with door body close to the side of door body；
The radius of the security bar is consistent at a distance from door-hinge axis to side doorframe.
Side of the security bar far from door body and side door frame contact and with side doorframe sliding contact, make security bar i.e.
It can be rotated with the rotation of door body, the crack between a door and its frame between doorframe and door body can also be filled, people is avoided to rotate in door body
Cheng Zhong falls into limbs since the crack between a door and its frame between door body and doorframe increases, crushes during causing door body to turn round.
The present invention installs finger pinch device additional on the basis of existing door body, without changing the structure of revolving door itself
Realize the technical effect for preventing clamp hand, structure is simple, and at low cost, installation is cheap.
Further, the card slot is the U-type groove extended along door-hinge vertical direction, the shape and door body edge one of the card slot
It causes and the card slot and door body is interference fitted.In the door body and the card slot of insertion on one side of door-hinge rotation connection, make security bar packet
The edge for wrapping up in door body is connected as one finger pinch device and door body, from debugging, long service life.
Further, the side doorframe be additionally provided with and security bar close to jointing plate, the jointing plate and security bar
Gap is small, can further prevent that clamp hand occurs at closing time.
Further, the jointing plate close to the side of security bar be arcwall face with security bar clearance fit, the fitting
Side of the plate far from security bar is the plane vertical with side doorframe, using jointing plate by the contact position of security bar and side doorframe
Or existing fine gap more preferably covers.Preferably, the junction of the jointing plate and side doorframe seamlessly transits, and makes it more
Beauty, convenient for cleaning.
Further, the gap of the arcwall face and security bar from close to door body a laterally closer side doorframe side by
It is cumulative big；The arcwall face is zero close to the side of door body and the gap of security bar, makes security bar and jointing plate linear contact, makes
Do not have between protective plate and jointing plate can clamp hand gap, while minimizing the friction between jointing plate and security bar again
Power makes to push door body rotation more laborsaving.
Further, the jointing plate is arranged in inside and outside door body along the axisymmetrical of door-hinge, realizes outside in door body
Prevent the technical effect of clamp hand.
Further, the finger pinch device further includes the shaft that both ends are mounted on the doorframe of side, the jointing plate with
Shaft rotation connection；It is additionally provided in the shaft for providing the torque spring of turning power for jointing plate；The jointing plate exists
It is contacted under the action of torque spring with security bar line.Torque spring makes jointing plate and security bar remain linear contact, makes to prevent
Do not have always between backplate and jointing plate can clamp hand gap, while minimizing the friction between jointing plate and security bar again
Power makes to push door body rotation more laborsaving.
Preferably, the upper and lower ends of jointing plate are arranged in the torque spring, and the turning power for being subject to jointing plate is more equal
It is even, prolong the service life.
Further, the shaft is the multi-diameter shaft that lower end diameter is greater than upper end diameter, the jointing plate and shaft diameter compared with
The lower end of small one section of socket and the jointing plate is placed on what lesser one section of shaft diameter was formed be relatively large in diameter one section
On step, position is fixed, and assembly is simple, stability is good.
Preferably, the jointing plate, shaft, torque spring are arranged in inside and outside door body along the axisymmetrical of door-hinge,
Realize that the inside and outside outside of door body prevents the technical effect of clamp hand.
