Embodiment 1

[0024] Such as Figure 1-2 As shown, a folding door device with automatic folding function includes at least two door bodies 1 and elastic hinges 2. The groove 4 is docked, and the longitudinal protrusions 3 and the longitudinal grooves 4 are used to connect each door body 1 of the folding door. On the one hand, it can enhance the firmness of the folding door, and on the other hand, it can effectively insulate the temperature, prevent dust, and reduce noise. Sound insulation, shielding, etc.; the elastic hinge 2 is connected to the inner side of the interface of the two door bodies 1, and the elastic hinge 2 is used to connect between the two folding door bodies 1, which can realize the automatic opening of the folding door after opening. Folding function; a hinge is set on the inner side of the interface of the two doors. On the one hand, the hinge does not affect the sealing of the interface. On the other hand, after the folding door is closed with a safety lock, the folding...

Embodiment 2

[0026] Such as image 3 As shown, a folding door device with automatic folding function, on the basis of Embodiment 1, the elastic hinge 2 includes a fixed shaft 5, a fixed leaf 6, and a rotating leaf 7, and the fixed leaf 6 includes concave blades 8 and are respectively arranged on The fixed leaf shaft sleeve 9 on both sides of the concave blade 8 notch, the rotating leaf 7 includes a square blade 10 and a rotating leaf shaft sleeve 11 located on the square blade 10, and the fixed shaft 5 is inserted in the fixed leaf shaft sleeve 9 and Turn the page shaft sleeve 11 inside. Torsion springs 12 are respectively arranged on the fixed shafts 5 at both ends of the rotating leaf bushing 11, and the two ends of the torsion spring 12 are respectively fixedly mounted on the corresponding fixed leaf bushing 9 and the rotating leaf bushing 11. A positioning groove 13 is provided in the middle of the rotating leaf sleeve 11 , and a retaining spring 14 is provided on the fixed shaft 5 co...

Embodiment 3

[0028] Such as Figure 4 As shown, a folding door device with automatic folding function, on the basis of Embodiment 1, a sound insulation strip 15 is arranged in the longitudinal groove 4 . The section of the sound insulation strip 15 is a D-shaped hollow structure. The sound insulation strip is made of extrudable soft rubber material, which can effectively play the role of temperature insulation, dust prevention, noise reduction and sound insulation, and shielding.

Abstract

The invention discloses a folding door device with automatic folding function, which comprises at least two door bodies and elastic hinges, and the two adjacent door bodies are respectively butted through longitudinal protrusions and longitudinal grooves arranged on the side end faces, The elastic hinges are connected to the inner sides of the joints of the two door bodies. Each door body of the folding door adopts vertical protrusions and longitudinal groove structures to connect, on the one hand, it can enhance the firmness of the folding door, on the other hand, it can effectively play the role of temperature insulation, dust prevention, noise reduction and sound insulation, and shelter; There are hinges on the inner side of the interface between the two doors. On the one hand, the hinge does not affect the sealing of the interface. , Pushing or pulling outside, the folding door will not fold, it is as strong as an ordinary anti-theft door, and it can be automatically folded when the safety lock is opened.

Description

technical field [0001] The invention relates to the field of door industry manufacturing, in particular to a folding door device with an automatic folding function. Background technique [0002] Folding doors are mainly suitable for partitions and screens in workshops, shopping malls, office buildings, exhibition halls and home decorations. Both inner and outer doors can be installed and used, which can effectively play a role in temperature insulation, dust prevention, noise reduction, Covering etc. The folding door is multi-leaf folding, which can be folded to the side and takes up less space. At present, the folding door still has complex structure and high cost; poor sound insulation effect and no automatic folding function. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a folding door device with automatic folding function, and solve the problems of complex structure and high cost, poo...
