Abstract
The utility model relates to an adjustable door body mechanism which comprises a row of annular door brackets, folding type fence components, two front fences and two pairs of rear equilong rotary rods, wherein the annular door brackets are separated and are provided with foot wheels, and the folding type fence components are connected among the annular door brackets. The folding type fence components are provided with middle annular door brackets, two front fences are positioned at both sides of the front, the two pairs of rear equilong rotary rods are positioned at both sides of the lower part at the rear, and the middle parts of the rotary rods are hinged. The utility model is characterized in that the middle hinged point of each pair of the rear equilong rotary rods is respectively connected with a rear vertical rod, and the upper part of the rear vertical rod is extended forwards and is connected with the upper end of a vertical rod of the front fence to form an arch-shaped rod. The door body mechanism has the obvious advantages of stable structure, compactness, firmness, etc.
Description
The utility model relates to a kind of telescopic door body mechanism.
The patent No. is to disclose a kind of telescopic door body mechanism in " automatic folding door " utility model patent of 942005057.6, before it comprises a row having separately, the circular portal frame of back montant and front and back castor, and be connected in collapsible bar assembly between each circular portal frame, collapsible bar assembly has the intermediate annular door frame, be positioned at two front panels of both sides, front and be positioned at the back isometric bull stick that two pairs of central parts of both sides, below, back are hinged, front panel has montant and the center is articulated on the montant respectively, isometric bull stick before two couple of below, the lower end of isometric bull stick is articulated in respectively on the preceding montant of the preceding montant of circular portal frame and center annular door frame before every pair, the upper end of isometric bull stick has sliding pin before every pair, be bumped into respectively in the top chute of montant before the top chute of montant before the circular portal frame and the intermediate annular door frame, after every pair the lower end of isometric bull stick be articulated in respectively circular portal frame back montant and in behind every pair of the bottom of back montant of circular portal frame the upper end of isometric bull stick have sliding pin, be bumped into respectively in the middle part chute of back montant of the middle part chute of montant after the circular portal frame and center annular door frame.
The major defect that exists is that the front panel rear structure is sparse, and the montant of front panel is easily by bending when going to pot.
The purpose of this utility model is that a kind of telescopic door body mechanism will be provided, and this mechanism structure is closely knit, stable and firm.
Construction features of the present utility model are to be connected with the back montant respectively on the center hinge contact of isometric bull stick behind every pair of above-mentioned door body mechanism, and the top of back montant is unified into arch bar on extending montant with front panel forward.
So being connected into ogive by the back montant on the isometric bull stick of montant and back of front panel, the utility model can make this body mechanism structure closely knit, stable and firm.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is the lateral view of existing telescopic door body mechanism.
Fig. 2 is a lateral view of the present utility model,
Fig. 3 is the elevation of the utility model deployed condition.Fig. 4 is the A-A sectional view of Fig. 3, and Fig. 5 is front panel and circular portal frame and center annular door frame coupling part view.
With reference to accompanying drawing, before the utility model comprises a row having separately, back montant 1,2 and front and back castor 3,4 circular portal frame, and be connected in collapsible bar assembly between each circular portal frame, collapsible bar assembly has intermediate annular door frame 5, be positioned at two front panels of both sides, front and be positioned at the back isometric bull stick 6 that two pairs of central parts of both sides, below, back are hinged, front panel has montant 7 and center and is articulated on the montant respectively, isometric bull stick 8 before two couple of below, the lower end of isometric bull stick is articulated in respectively on the preceding montant of the preceding montant of circular portal frame and center annular door frame before every pair, the upper end of isometric bull stick has sliding pin before every pair, be bumped into respectively in the top chute 9 of montant before the top chute 12 of montant before the circular portal frame and the intermediate annular door frame, the lower end of isometric bull stick is articulated in the bottom of the back montant of the back montant of circular portal frame and center annular door frame respectively after every pair, the upper end of isometric bull stick has sliding pin after every pair, be bumped into respectively in the middle part chute 10 of back montant of the middle part chute of montant after the circular portal frame and center annular door frame, the center hinge contact that it is characterized in that isometric bull stick after every pair is connected with back montant 11, and the top of back montant is unified into arch bar on extending montant with front panel forward.
