Embodiment 1

[0024] Such as Figure 1-2 As shown, a folding structure for a multi-section extension arm of a single-arm three-dimensional measuring line marking instrument includes at least two door bodies 1 and elastic hinges 2, and the two adjacent door bodies 1 are respectively arranged on the side end faces. The longitudinal protrusions 3 and the longitudinal grooves 4 are docked, and the longitudinal protrusions 3 and the longitudinal grooves 4 are connected between 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 Temperature insulation, dustproof, noise reduction, 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. The automatic folding function of the folding door after opening can be realized; the hinge is set on the inner side of...

Embodiment 2

[0026] Such as image 3 As shown, a folding structure for a multi-section extension arm of a single-arm three-dimensional measuring line marking instrument, on the basis of Embodiment 1, the elastic hinge 2 includes a fixed shaft 5, a fixed hinge 6, a rotating hinge 7, and a fixed hinge 6 Comprising concave blades 8 and fixed leaf sleeves 9 respectively arranged on both sides of the concave blade 8 notches, the rotating blade 7 includes square blades 10 and rotating leaf sleeves 11 arranged on the square blades 10, the fixed shaft 5 is inserted It is located in the fixed leaf bushing 9 and the rotating leaf bushing 11. 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 ...

Embodiment 3

[0028] Such as Figure 4 As shown, a folding structure for a multi-section extension arm of a single-arm three-dimensional measuring line marking instrument, 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 structure for a multi-section extension arm of a single-arm three-dimensional measurement scriber. The folding structure comprises at least two door bodies and elastic hinges. The two adjacent door bodies are in butt joint through longitudinal protrusions and longitudinal grooves formed in the side end faces. The elastic hinges are connected to the inner side faces of the butt joints of the two door bodies. Due to the fact that the door bodies of a folding door are in butt joint through the longitudinal protrusions and the longitudinal grooves, on the one hand, the integral firmness of the folding door can be strengthened, and on the other hand, the effects of heat insulation, dust prevention, noise reduction and insulation, shielding and the like are effectively achieved; and by arranging the hinges on the inner side faces of the butt joints of the two door bodies, the hinges do not affect the sealed butt joint of the joints, and besides, after the folding door is closed with a safety lock, the folding door and a door frame are closed in a matched mode, the folding door cannot fold no matter whether people push or pull the folding door from the inside or the outside, the folding door is as firm as an ordinary antitheft door, and the folding door can be folded automatically after the safety lock is unlocked.

Description

technical field [0001] The invention relates to the field of door industry manufacturing, in particular to a folding structure for a multi-section extension arm of a single-arm three-dimensional measuring and marking instrument. 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, to provide a folding structure for the multi-section extensio...
