Abstract

The utility model relates to a free-revolving door, which is characterized in that a rotation mechanism and a guiding mechanism are respectively installed on the positions of an upper and a lower doorframes corresponding to a door leaf, and the center of the suspension shaft of the rotation mechanism keeps an eccentric distance with the center of the guiding shaft of the guiding mechanism. The utility model can cause the door to open 180 DEG in positive or negative direction, and the door leaf can shut off lightly and automatically when the finger leaves; the door leaf can be positioned for ventilation after being opened 90 DEG; the utility model can produce differently formed doors in this structure according to different conditions and situations.

Description

Free-revolving door

The utility model belongs to EO6B class technology, particularly belongs to the door of using on a kind of building.

In known technology, a kind of free door of use is made up of door leaf and doorframe etc., and it is to utilize free hinge or spring that door leaf is fixedly mounted on the doorframe, and uses as rotating shaft.This door can only be spent to opening 90 by folk prescription, thereby has caused many inconvenience in unlatching.Such as: in the workshop of coming in and going out the many factories of people, when opening door, all can open 90 degree at any time in the opposite direction, shortened the application life of door, and use very not convenient.In addition, use this kind door, can not go back to original position and automatic location automatically, need employing latch or hook, can make troubles to the user like this if prefer the position.

The purpose of this utility model be to overcome the deficiency of known technology and provide a kind of can be just or freely opens and can return automatically that original position is also located and need be with a kind of novel building door of free hinge or spring in the other direction.

The purpose of this utility model is achieved in that

A rotating mechanism is installed between upper door frame 11 and the door leaf 3 corresponding with it, that is: a termination that will have a hanging axis 1 of through hole is fixedly mounted in the groove that upper door frame has by nut 2, the other end of hanging axis install have a cross bath and have the location-plate 4 that through hole can make hanging axis pass through in it, again by through hole on the hanging axis and the vertical trunnion shaft 6 that penetrates with hanging axis, these two ends are separately installed with the copper opinion 8 that can do rolling friction and the nut 9 that prevents the outside play of copper wheel, corresponding door leaf 3 positions that hanging axis is installed with upper door frame also have groove, be installed with framework 5 in the groove, framework is fixed by bolt 7 and location-plate; Between lower door frame 10 and the door leaf corresponding a guiding mechanism is installed also with it, that is: lower door frame one termination with rotating mechanism in the hanging axis center have the position of eccentric distance to be installed with the axis of guide parallel 12 with hanging axis by bolt 13, in its leading truck 15 that fixedly is equipped with by corresponding with it door leaf position; The external surface of rotating mechanism and guiding mechanism is covered with closure casing respectively.

The bonding surface place of door leaf of the present utility model and door leaf can be separately installed with the metastable magnet 14 that keeps door leaf.Around the door leaf the soft rubber weather strip with winter protection can also be installed.The inside of door leaf also can filling have the fireproof glass wool.

The advantage that the utlity model has shows as: because rotating mechanism and guiding mechanism are housed, can make Men Nengcong just or in the other direction open 180 degree, when touching door leaf with finger, door leaf is just opened gently; After finger left, door leaf can cut out again gently lentamente automatically.In addition, after opening 90 degree, door leaf can be convenient to surely ventilate.The utility model can produce the suitable multi-form door with this structure according to different condition and different occasions.

The utility model has following accompanying drawing:

Fig. 1 is the utility model structural representation;

Fig. 2 is an A-A cut-away view among Fig. 1;

Fig. 3 is the location-plate plan structure schematic diagram among Fig. 1;

Fig. 4 is the right TV structure schematic diagram of Fig. 3.

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:

Use the utility model can select unlike material for use, as aluminium alloys, corrosion resistant plate etc., the simple gate or the opposite house (two-door) that can be used on respectively under the different occasions such as shop, hospital, hotel, dining room use.When selecting for use simple gate to use, earlier guiding mechanism is fixedly installed between lower door frame 10 left end heads and the door leaf 3 corresponding with lower door frame, again with rotating mechanism and guarantee wherein hanging axis center and axis of guide center eccentric position in the guiding mechanism be fixedly installed in upper door frame 11 and with the corresponding door leaf 3 of upper door frame between.After two kinds of mechanisms are housed, be not subjected to environment pollution and service firing durable flexibly, cover with closure casing more respectively for keeping them.

The utility model when work when the trunnion shaft in the rotating mechanism 6 fits like a glove with cross bath in the location-plate 4 and trunnion shaft when parallel with upper door frame, is automatic closed condition; When door leaf rotates, be loaded on copper wheel 8 on the trunnion shaft and just leave the cross bath in the location-plate and roll, this moment, door was an opening, the people leaves the back door and slowly closes again.When needs ventilate, flat transverse axis can be fitted like a glove with cross bath in the location-plate and trunnion shaft when vertical with upper door frame, door promptly can be positioned on 90 degree directions.

When selecting for use opposite house (two-door) to use, after two-door installation respectively, can magnet 14 be housed at the bonding surface place of door leaf and door leaf, when door leaf cut out, its suction of magnet performance kept the relatively stable of door.

For making door have fire-proof function, can be at door leaf inner filling glass wool; For making door have the winter protection function, the soft rubber weather strip can be housed around door leaf.

Claims

1, a kind of free turnstile, be by door leaf 3, compositions such as upper door frame 11 and lower door frame 10, it is characterized in that: a rotating mechanism is installed between upper door frame 11 and the door leaf 3 corresponding with it, that is: a termination that will have a hanging axis 1 of through hole is fixedly mounted in the groove that upper door frame has by nut 2, the other end of hanging axis is installed and is had cross bath and the location-plate 4 that hanging axis is passed through that have through hole in it, again by through hole on the hanging axis and the vertical trunnion shaft 6 that penetrates with hanging axis, these two ends are separately installed with the copper wheel 8 that can do rolling friction and the nut 9 that prevents the outside play of copper wheel, corresponding door leaf 3 positions that hanging axis is installed with upper door frame also have groove, be installed with framework 5 in the groove, framework is fixed by bolt 7 and location-plate; Between lower door frame 10 and the door leaf 3 corresponding a guiding mechanism is installed also with it, that is: lower door frame 10 1 terminations with rotating mechanism in the hanging axis center have the position of eccentric distance to be installed with the axis of guide parallel 12 with hanging axis by bolt 13, it is installed with the axis of guide parallel with hanging axis 12 by corresponding with it door leaf position, and it is by in the leading truck 15 that the door leaf position of correspondence is installed with it; The external surface of rotating mechanism and guiding mechanism is covered with closure casing respectively.
