Abstract

The utility model discloses an improved structure of multi-fold rib, which assorts the nest of an umbrella bar. The utility model mainly consists of a support rib, a top rib, a middle rib, a loop line and a tail rib; wherein the loop line consists of a main loop line and a small loop line; the one end of the main loop line is hinged to the outer end near the support rib, whereas the other end of the main loop line pierces the slide bushing at the lower of the middle rib first and then is hinged to the small loop line; and the other end of the small loop line is hinged to the tail rib at the inner end of the tail rib connector. As the small loop line agilely rotates, thus the umbrella can be totally brought together.

Description

The improvement structure of many folding umbrella frames

Technical field

The utility model relates to a kind of umbrella rib structure, particularly relates to a kind of improvement structure of many folding umbrella frames.

Background technology

A kind of known many folding umbrella frames, as shown in Figure 1, mainly by fulcra 3 ', parietal bone 4 ', interior connection bone 6 ', middle bone joint 71 ', middle bone 7 ', loop line 8 ', coccyx joint 91 ', coccyx 9 ' form.Fulcra 3 ' the inner be hinged on down nest 23 ' on, parietal bone 4 ' the inner be hinged on nest 21 ' on, last nest 21 ' be fixed on umbrella rod 1 ' the top, following nest 23 ' sleeve to umbrella rod 1 ' on; Parietal bone 4 ' the outer end be hinged on fulcra 3 ' the middle part; In connect bone 6 ' the inner be hinged on parietal bone 4 ' place, nearly outer end, the outer end be hinged on middle bone joint 71 ' on; Fulcra 3 ' the outer end be hinged in bone joint 71 ' the outer end, middle bone 7 ' the inner be fixed in bone joint 71 ' on; Loop line 8 ' the inner be hinged on fulcra 3 ' near outer end place, the outer end be hinged on coccyx joint 91 ' the inner, middle bone 7 ' the outer end be hinged on coccyx joint 91 ' near inner place, coccyx 9 ' the inner be fixed in coccyx joint 91 ' on.Because the loop line 8 of this many folding umbrella frames ' have only, though have characteristic of simple structure, coccyx 9 when folding ' bone 7 in can't fitting fully ', make umbrella not fold fully.

The utility model content

The purpose of this utility model is to provide a kind of improvement structure of many folding umbrella frames, makes umbrella when folding, and coccyx and middle bone reach free folding and unfolding, and fold fully.

In order to achieve the above object, the utility model is rolled over the improvement structure of umbrella frame more, cooperates the umbrella nest of umbrella rod and implements, and mainly is made up of fulcra, parietal bone, middle bone, loop line, coccyx; Loop line is made of main loop line and little loop line, and main loop line one end is hinged on fulcra near the place, outer end, and the cover and the little loop line of bone lower end were hinged during the other end passed, and the other end and the coccyx of little loop line are hinged, and are hinged on the inner of coccyx joint.

Because the loop line that the utility model adopted is to be made of for two sections main loop line and little loop line, and the two ends of little loop line are hinged with main loop line and coccyx respectively.When strutting, middle bone arches, and main loop line is curved to be tightened, and drives little loop line, makes both point-blank, and simultaneously little loop line drives coccyx and swings laterally, is in softened state; When folding, middle bone and fulcra are amounted to, and main loop line external force discharges, and promotes little loop line, and little loop line promotes coccyx and inwardly swings, make coccyx fit fully in bone.Because little loop line rotates flexibly, make umbrella fold the back compact conformation, volume reduces.

The specific embodiment

As shown in Figure 2, the utility model is rolled over the improvement structure of umbrella frame more, and umbrella rod 1 is provided with umbrella nest 2, comprises nest 21, middle nest 22, following nest 23, and last nest 21 is fixed on umbrella rod 1 top, and middle nest 22 and following nest 23 close respectively in umbrella rod 1.Cooperate shown in Fig. 3,4, umbrella frame mainly comprises fulcra 3, parietal bone 4, hamate bone 5, interior connection bone 6, middle bone 7, loop line 8, coccyx 9.The inner of parietal bone 4 is hinged on the nest 21, and on the nest 22, the inner of hamate bone 5 was hinged on down on the nest 23 during the inner of fulcra 3 was hinged on.The outer end of parietal bone 4 is hinged on the middle part of fulcra 3, and an end of interior connection bone 6 is hinged on the parietal bone 4, and the other end is hinged with middle bone 7 and fulcra 3 by middle bone joint 71.Loop line 8 is made of main loop line 81 and little loop line 82, and main loop line 81 1 ends are hinged on fulcra 3 near the place, outer end, and the sliding sleeve 72 of bone 7 lower ends and little loop line 82 were hinged during the other end passed, and winner's loop line 81 can be moved in this sliding sleeve 72; The other end and the coccyx of little loop line are hinged, and are hinged on the inner of coccyx joint 91.

Shown in Fig. 5-10, when umbrella strutted, middle nest 22 and following nest 23 were along moving on the umbrella rod 1, middle bone 7 arches, and main loop line 81 curved tightening drive little loop line 82, make both point-blank, simultaneously little loop line 82 drives coccyx 9 and swings laterally, makes umbrella be in softened state.

When umbrella folds, middle nest 22, following nest 23 move down along umbrella rod 1, middle bone 7 is amounted to fulcra 3, main loop line 81 external force discharge, promote little loop line 82, the coccyx 9 that little loop line 82 promotes to be hinged on the coccyx joint 91 is inwardly swung around coccyx joint 9 and middle bone 7 pin joints, and bone 7 during coccyx 9 is fitted fully makes umbrella to fold fully.

Claims (1)

1, rolls over the improvement structure of umbrella frame more, cooperate the umbrella nest of umbrella rod and implement, mainly form by fulcra, parietal bone, middle bone, loop line, coccyx, it is characterized in that: loop line is made of main loop line and little loop line, main loop line one end is hinged on fulcra near the place, outer end, the sliding sleeve and the little loop line of bone lower end were hinged during the other end passed, and the other end and the coccyx of little loop line are hinged, and are hinged on the inner of coccyx joint.
