The closed type folding safety door is composed of an integral door leaf, a door frame, a guide wheel, a rolling wheel, hinges, and a door lock. The utility model is mainly characterized in that the integral door leaf is composed of a translational door leaf and a rotary door leaf, ordinary hinges are arranged between the two door leaves, and a high-central hinge and a high-central spring hinge are taken as the connection bodies; the translational door leaf is positioned at one side of the integral door leaf, and the lower part of the translational door leaf is provided with the rolling wheel. The opening of the closed type folding safety door is easy and flexible, and a 'closed type' can be formed at the time of closure.

Description

Sealing-type folding safety door

The utility model relates to a kind of closed folding safety door of building field, is applicable to the use of family and each workplace.

At present, along with the develop rapidly of science and technology and improving constantly of living standards of the people, people more and more pay attention to living and the space quality and the safety of workplace, thereby also strict further to the requirement of building unit " door ".

In the prior art, with practical, attractive in appearance be prerequisite, have the various Door for building little, that security performance is high that take up room concurrently, liked by people.Promptly disclose " a kind of fireproof steel rolling door " as Chinese patent application 88CN2031436U, this door can be controlled lifting by transmission system; Chinese patent application 88CN2031833U then discloses a kind of " horizontal sliding door " for another example, and this door can open and close along the direction perpendicular to the doorframe plane when the door body is stressed, and this can be the indoor personnel of turnover and creates a vision and psychological spatial transition.But still there is certain defective in above-mentioned binomial patent, then needs to adopt door sheet transmission lifting gear as 88CN2031436U; 88CN2031883U then need be in the certain space of indoor reservation.Under the lower situation of the present power supply shortage of China and building standard, the also unsuitable large tracts of land of above-mentioned two kinds of Door for building adopts.At present widely popular on the market is a kind of " paling form " door, this door can form paliform when closing, but when opening then horizontal sliding to a side of doorframe, but it is closed that this door can not form when closing, and need set up other door in addition at certain space and constitute " dysopia " and strengthen its safety.

The purpose of this utility model is that a kind of closed folding safety door will be provided, and it can solve the occupation problem of indoor and outdoor spaces effectively.

The purpose of this utility model is achieved in that to adopt the translation door leaf and rotate door leaf and is combined into whole door leaf, between door leaf, adopt common folding, high central folding page or leaf and high central spring folding as connected body, the translation door leaf is positioned at a side of whole door leaf, bottom at the translation door leaf is provided with roller, the top and the bottom of whole door leaf are provided with directive wheel, directive wheel can move in the track that is parallel to the doorframe plane, opposite side at whole door leaf longitudinally equidistantly is equipped with common folding, with the integral door page fixing on doorframe.

The utility model is because be provided with high central spring folding between door leaf, so when opening the door, can between door leaf, not form the moment dead angle, simultaneously, translation door leaf that is provided with and roller, directive wheel etc. also make door keying flexibly, freely, door can form " closed " when closing.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the structural representation according to the closed folding safety door that the utility model proposes.

Fig. 2 is the rear elevation of closed folding safety door.

Fig. 3 is the vertical view of Fig. 1 along the A-A line.

Fig. 4 is the utility model door leaf opening schematic diagram.

Fig. 5 is the vertical view of Fig. 4 along A '-A ' line.

Fig. 6 is the front view of the high central spring folding that the utility model adopted.

Fig. 7 is the face upwarding section of Fig. 6 along the B-B line.

Describe details and working condition in detail below in conjunction with accompanying drawing according to the closed folding safety door that the utility model proposes:

Whole door leaf comprises translation door leaf 3 and rotates door leaf 2, translation door leaf 3 is positioned at a side of whole door leaf, in the bottom of translation door leaf 3 roller 9 is installed, between translation door leaf 3 and rotation door leaf 2, common folding 4 is installed equidistantly longitudinally, be provided with high central spring folding 6 at the longitudinal middle part that rotates the odd number connection place that door leaf 2 counted by an end, and longitudinally high central folding page or leaf 5 is being installed with the equal height that common folding is installed, the centre-height δ of high central folding page or leaf 5 is identical with the centre-height δ of high central spring folding 6, the common relatively folding of the centre-height of the two, the even number connection place of being counted by an end at rotation door leaf 2 longitudinally equidistantly is equipped with common folding 4, its height is identical with the height of adjacent high central folding page or leaf 5, on the whole door leaf, directive wheel 8 respectively is housed down, directive wheel 8 can move in upper rail 10 that is parallel to the doorframe plane and lower guideway 11, whole door leaf is fixed on the doorframe 1 by the common folding 4 that longitudinally is equally spaced, and is equiped with door lock 7 on translation door leaf 3.

The purpose that high central spring folding 6 is installed is to make to rotate between the door leaf still to keep certain operating angle when door is closed, when this angle can guarantee door opened, avoid between each door leaf, forming the moment dead angle, the effect that high central folding page or leaf 5 is installed is in order to cooperate high central spring folding 6 work effectively, avoid high central spring folding 6 stressed too concentrated, when door is opened, the door leaf connection place that high central folding page or leaf 5 and high central spring folding 6 are installed all is folded to the outside of door, when door was closed, whole door leaf can be realized " closed ".

Specify the structure and the installation situation of the high central spring folding that the utility model adopts below in conjunction with accompanying drawing 6,7.

Adopt rivet 14 that spring 15 is fixed on by pad 13 and rotate on the door leaf 2, band cap hinge pin 16 is passed by the axle center of two hinge flaps 12 and spring 15, and hinge flap 12 also is fixed on and rotates on the door leaf 2 by being the even rivet 14 that distributes for how much.

Claims

1, a kind of closed folding safety door, form by whole door leaf, doorframe, directive wheel, roller, folding and door lock, it is characterized in that: whole door leaf is made up of translation door leaf and rotation door leaf, between the door leaf be by common folding, high central folding page or leaf and high central spring folding as connected body, the translation door leaf is positioned at a side of whole door leaf.

2, according to the described closed folding safety door of claim 1, it is characterized in that: between translation door leaf and rotation door leaf, common folding is installed equidistantly longitudinally, be provided with high central spring folding at the longitudinal middle part that rotates the odd number connection place that door leaf counted by an end, and longitudinally high central folding page or leaf being installed with the corresponding height that common folding is installed, the even number connection place of being counted by an end at the rotation door leaf longitudinally equidistantly is equipped with common folding.
