Abstract

A connector for folding rods comprises a first connecting part and a second connecting part. The outer end of the first connecting part is provided with a groove. The side wall of the groove is provided with a fixing hole. The second connecting part plugs in the groove. The second connecting part is provided with a long groove hole. Two connecting parts are hinged together by an articulated element which passes through the fixing hole and the long groove hole. A boss extending inwards is arranged on the periphery of the fixing hole on the inner face of the side wall of the groove of the first connecting part. A blocking station which can contacts the periphery of the boss of the first connecting part is arranged on both sides of the second connecting part and the lower terminal of the long groove hole. When the second connecting part unfolds, the blocking station of the second connecting part completely contacts the inner side wall of the boss of the first connecting part, which causes the two connecting parts unable to do relative rotation. The contact between the blocking station on both sides and the boss is surface contact, not point contact as the prior art of convention, as a result, the connector for folding rods has steady position and long service life.

Description

Folding rod member link

Technical field

The utility model relates to the accessory of a kind of leisure or camp appliances, refers to a kind of folding rod member link especially.

Background technique

In the prior art, leisure such as leisure chaise longue, tent or camp appliances transport for convenience, carry or collect, and adopt folding structure usually, and like this, the utilization of foldable poles on collapsible leisure chaise longue or tent just is seen everywhere.

Fig. 1 is a kind of common rod member link that is used for collapsible shelter, this rod member link is hinged by first joint 280 and second joint 290 and forms, and this first, second joint 280,290 respectively with two sections rod members 250 ' affixed, with realize two rod members 250 ' folder function.

The outer end of described first joint 280 is provided with fluting, and the sidewall of this fluting is provided with the fixed hole that can plug articulated elements 281, and this side wall inner surface also is provided with guiding groove 282, has a strong point 284 in the axial inboard of these first joint, 280 flutings in addition; The outer end of described second joint 290 inserts in the fluting of first joint 280, which is provided with slotted hole 291 is run through by described articulated elements 281, thereby it is second joint 290 and first joint 280 is hinged, these second joint, 290 axial end portions are provided with the support slot 292 that can be stuck in the described strong point 284, and its both sides are provided with the guide pad 293 that can insert in the described guiding groove 282.

Above-mentioned rod member link is when stretching, shown in Fig. 2 A, the guide pad 293 of second joint 290 inserts in the guiding groove 282 of first joint 280, and the strong point 284 that makes first joint 280 is stuck in the support slot 292 of second joint 290, two joints 280,290 are fixed mutually, and can't rotate, thereby make the rod member 250 of both sides ' open.And when desiring to make two rod members 250 ' folding, shown in Fig. 2 B, outwards pull out second joint 290 its guide pad 293 is broken away from the guiding groove 282 of first joint 280, rotate second joint 290 again, can be with two rod members 250 ' folding.

Yet, the fixing mode of above-mentioned rod member link adopts the guide pad 293 and the strong point 284 to realize, and rod member 250 ' after expansion, bear certain support force, especially for tent, its holding strength is bigger, the long-term use, described guide pad 293 or the strong point 284 easy-rupturings and damage, thus working life of tent influenced; In addition, the support of this approximate point-like, as apply external force shown in arrow among Fig. 2 A, then two joints 280,290 of this rod member link easily disconnect, thereby tent is subsided.

The model utility content

But technical problem to be solved in the utility model is to provide the folding rod member link of a kind of firm support and long service life.

For solving the problems of the technologies described above, technical solution of the present utility model is: a kind of folding rod member link, constitute by first joint and second joint, outer end on this first link is provided with fluting, the sidewall of this fluting is provided with fixed hole, second link inserts in the fluting, which is provided with slotted hole, and an articulated elements runs through described fixed hole and slotted hole and two links are hinged; The side wall inner surface fixed hole periphery of described first link fluting is provided with the boss that extends internally; The described second link both sides, slotted hole lower end are provided with the Ka Tai of the boss periphery that can be resisted against first link.

The boss of described first link is the circular arc concentric with fixed hole near the fixed hole place.

After adopting such scheme, the utility model upon deployment, the Ka Tai of second link will be fully with the madial wall of the first link boss against, two links can't be rotated relatively again, and owing to realize between both sides Ka Tai and the boss going up for face and contact, its surface of contact is big, does not resemble approximate point-like contact the located by prior art, and therefore the location is firm, be difficult for subsiding, and owing to do not have projection or a salient point, the phenomenon that can occur rupturing not, long service life.

In addition, the boss of described first link is the circular arc concentric with fixed hole near the fixed hole place, and when launching or fold two rod members, the Ka Tai of the second link both sides will be along the circular arc periphery rotation of this boss, therefore the effect of this circular arc with guiding makes operation smooth and easy.

Embodiment

Please as shown in Figure 3, folding rod member link described in the utility model is made of first joint 1 and second joint 2, and this first,

second joint

1,2 is affixed with a rod member 3 respectively.

The outer end of described first link 1 is provided with fluting, and the sidewall of this fluting is provided with fixed hole 11, and side wall inner surface fixed hole 11 peripheries are provided with the boss 12 that extends internally, and this boss 12 is the circular arc concentric with fixed hole 11 near fixed hole 11 places.

Described second link 2 can insert in the fluting of first link 1, which is provided with fixed hole 11 that slotted hole 21, one articulated elementss 4 run through first link 1 with described slotted hole 21 and two

links

1,2 are hinged; Be provided with card platform 22 in second link, 2 both sides, slotted hole 21 lower ends in addition, this card platform 22 can be resisted against boss 12 peripheries of first link 1.

The utility model is when being in folded state, and as shown in Figure 4, first,

second link

1,2 pivots around articulated elements 4, can make two rod members 3 folding.

When desire was launched two

rod members

1,2, shown in Fig. 5 A, 5B and 5C, to inner rotary second link 2, the card platform 22 of its both sides will be along the circular arc periphery rotation of first link, 1 boss 11, so this circular arc has the effect of guiding, made operation smooth and easy; When second link 2 is rotated to be in a straight line with first link 1 after, inwardly push away second link 2 again, bottom up to first link, 1 fluting, at this moment, the card platform 22 of second link 2 will be fully with the madial wall of first link, 1 boss 12 against, two

links

1,2 can't be rotated relatively again, and owing to realize upward contacting between both sides card platform 22 and the boss 12 for face, its surface of contact is big, thereby forms firm positioning action.
