Abstract
The utility model provides a hand-squeezed prevention structure for a folding door. The hand-squeezing prevention structure for the folding door comprises a plurality of folding door leaves, the longitudinal side faces of two adjacent door leaves form an abutting part and an inclining part, the length of the abutting part is smaller than 10mm, and the incline angle of the inclining part is 20-30 degrees. Opening-closing shafts of hinges of the folding door are arranged at corners of the inner sides of the longitudinal side faces of the door leaves, and the abutting part of the adjacent door leaves is connected to one end of one opening-closing shaft to form a crevice which is narrower than 1mm after the folding door is closed. An included angle, facing an operator, of 40-60 degrees is gradually formed between the two adjacent door leaves in the closing process of the folding door. When the fingers of the operator are just located in the crevice between the two door leaves, the fingers are squeezed out from the door crevice along with the formation of the included angle between the two door leaves, and accidents that fingertips are pinched off or crushed are avoided. According to the hand-squeezing prevention structure for the folding door, the mounting mode of the hinges enables the crevice, formed in the closing process of the door, between the two door leaves to be narrowed down greatly, the safety performance of the folding door in the closing process is improved further, and the appearance of the folding door is attractive.
Description
Technical field
The utility model relates to a kind of structure of folding door, is specifically related to the pinch-proof structure for folding door, belongs to the gate technique field.
Background technology
Common folding door is to be hinged by the door leaf that many fans can fold to form, and the open and close of folding door are by the folding of multiple leaf door fan or open to realize.The longitudinal side 2 ' of two door leafs 1 ' that as shown in Figure 3, existing folding door is adjacent is the plane.Two adjacent door leafs 1 ' were positioned at same plane, fit together perfectly between two door leafs, do not have the slit when Folding wing was closed! So very possible because child plays or the reason such as people's distraction in the process of the open and close that realize folding door, door, hand still was in the slits between the adjacent two fan door leafs when window was closed, and caused the tong event to occur.Child particularly, hand is easier putting in the slit, and health is damaged.
Occur for fear of above-mentioned phenomenon, existing folding door generally is that the slit between the door leaf is larger when folding door is designed to open and close, even hand folding can not clip broken yet, but this design aesthetic appearance is poor.
The folding door that also has between adjacent two fan door leafs soft material is set or placement prevents the chock that hand enters, but above design all can affect the aesthetic appearance of folding door, and since increased parts quantity and so that cost increase.
In addition, as shown in Figure 4, because in the general mounting method of the hinge goods of folding door, the switch shaft 4 ' of folding door hinge 3 ' can depart from the central axis of door leaf 1 ' longitudinal side 2 ' medial angle and produce the slit a ' of switching.
For existing folding door open with closing process in the potential safety hazard that exists, be necessary to improve the designs of the pinch-proof structure between the adjacent two fan door leafs.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, safe and reliable folding door pinch-proof structure.
For achieving the above object, the utility model is by the following technical solutions:
A kind of pinch-proof structure for folding door comprises the folding door leaf of multi-disc, and two adjacent door leaf longitudinal side are formed with respectively abutting part and rake, and wherein the length of abutting part is below the 10mm, and the angle of inclination of rake is 20～30 degree.
The switch shaft of folding door hinge is arranged on the angle of described door leaf longitudinal side inboard, and when described folding door opened and closed, the slit that an end of the abutting part connecting valve axle of adjacent two door leafs forms was below the 1mm.
Effect of the present utility model:
Because adjacent two door leafs all have the rake that the angle of inclination is 20～30 degree, adjacent two door leaf oriented manipulation persons, one side has formed the angle of 40～60 degree gradually in the process that folding door is closed.When operator's finger exactly is positioned on the position of two door wing gaps, along with the formation of angle between two door leafs, finger is extruded from crack between a door and its frame gradually, and folding door is closed when extruding finger, the accident that prevents the finger tip pinch off and crush.
The mounting means of folding door hinge of the present utility model has further improved the safety when folding door is closed so that the slit that forms between two door leafs reduces greatly in the switching process, further improved the aesthetic appearance of folding door.

The specific embodiment
As shown in Figure 1, pinch-proof structure for folding door of the present utility model comprises the folding door leaf 1 of multi-disc, two adjacent door leaf longitudinal side are formed with respectively abutting part 2 and rake 3, and wherein the length of abutting part 2 is below the 10mm, and the angle of inclination of rake 3 is 20～30 degree.
In the folding door closing process, the abutting part of two door leafs rotates around the switch shaft 5 of hinge 4, and the rake of two door leafs is adjacent to each other, and oriented manipulation person one side has formed the angle of 40～60 degree gradually.Because the angle between two door leafs gradually from large to small in the folding door closing process, when operator's finger exactly is positioned on the position of two door wing gaps, formation along with angle between two door leafs, finger is extruded from crack between a door and its frame gradually, folding door is closed when extruding finger, has prevented the accident that the finger tip pinch off occurs and crush.
As shown in Figure 2, in pinch-proof structure of the present utility model, the switch shaft 5 of folding door hinge 4 is arranged on the angle of described door leaf longitudinal side inboard, and the slit a that an end of the abutting part connecting valve axle of adjacent two door leafs forms is below the 1mm.Mounting means with respect to existing folding door hinge, the mounting means of folding door hinge of the present utility model so that the slit that in the switching process, forms between two door leafs greatly reduce, further improve the safety when folding door is closed, further improved the aesthetic appearance of folding door.
The potential safety hazard that pinch-proof structure of the present utility model exists in actual mechanical process for folding door and designing meets people's actual demand in daily life fully, has very high economical and practical value.
