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, usually adopt folding structure, like this, the utilization of foldable poles on collapsible leisure chaise longue or tent just is seen everywhere, and just must link be arranged so that can fold between the foldable poles like this.This rod member link is made of two first joints that are articulated mutually and second joint, and two joints are connected with two rod members respectively again, thereby two rod members can be folded.In addition, between two joints, clamping device must be set, so that fix when two rod members launch, hundred in the past the fixing modes of folding rod member link adopt guide pad or the strong point and guiding groove or support slot to cooperatively interact and realize, yet rod member is after expansion, owing to will bear certain support force, especially for tent, its holding strength is bigger, the long-term use, guide pad or strong point easy-rupturing and damage, thus working life of tent influenced; In addition, the guide pad or the strong point are the support of approximate point-like, and when when overbending direction imposes external force, two joints of this rod member link easily disconnect, thereby tent is subsided.

At above-mentioned deficiency, this case claimant has applied for that a few days ago a key name is called " folding rod member link ", application number is: 200420071988.2 utility model patent, its structure as shown in Figure 1, first joint 1 of this rod member link ' be provided with boss 12 ', and second joint 2 ' be provided with can be resisted against first joint 1 ' boss 12 ' periphery card platform 22 '.When two rod members launch, second joint 2 ' card platform 22 ' general fully with first joint, 1 ' boss 12 ' madial wall against, make two joints 1 ', 2 ' can't rotate relatively again, and because card platform 22 ' with boss 12 ' between be actually face and contact, rather than approximate point-like contacts, therefore its surface of contact is big, the location is firm, is difficult for subsiding, and owing to do not have projection or salient point, the phenomenon that can occur rupturing not, long service life.

Yet above-mentioned two kinds of rod member links all can't be realized automatic expansion, and must be artificially to inner rotary two joints, again with two joints to inserting, can be fixed.In addition, after two rod members launch, outwards throw off as making two joints accidentally, then yielding and bend under the effect of external force.

The model utility content

Technical problem to be solved in the utility model is to provide a kind of and can launches automatically and fixing more firm folding rod member link.

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 joint is provided with fluting, the sidewall of this fluting is provided with fixed hole, second joint inserts in the fluting, which is provided with slotted hole, and an articulated elements runs through described fixed hole and slotted hole and two joints are hinged; And be connected with an elastic component between described first joint and second joint.

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.

Described elastic component one end is connected on the projection of first joint fluting bottom, and the other end then is connected on the hook of second joint and slotted hole heteropleural; This second joint is provided with one with the hook homonymy and holds the hole, and described elastic component passes in this appearance hole.

Described elastic component is spring or elastic cord.

After adopting such scheme, owing to be connected with an elastic component between two joints of the utility model rod member link, therefore when both sides rod member desire is launched, the elastic recovery effect of elastic component will make the automatically outside rotary expansion of two joints, and must be artificially to individual rotation; When two joints rotate to be in a straight line after, elastic component will continue pulling two joints, be inserted in the bottom of first joint fluting up to second joint, and two joints are fixed.This structure is not weighed the purpose that can reach automatic expansion, and this elastic component makes moreover protect all the time firm fixedly deployed condition owing to inwardly hold two joints all the time, even therefore be subjected to external force, also is difficult for producing distortion or folding.

Embodiment

As shown in Figure 2, folding rod member link described in the utility model, articulated mutually and constituted by first joint 1 and second joint 2, this first,

second joint

1,2 is affixed with a rod member 3 respectively, is connected with an elastic component 5 between described first joint 1 and second joint 2.In particular:

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

joints

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

Described elastic component 5 one ends are connected on the projection 13 of first joint, 1 fluting bottom, the other end then is connected on the hook 23 of second joint 2 and slotted hole 21 heteropleurals, this second joint 2 also is provided with one with hook 23 homonymies and holds hole 24 (as shown in Figure 3), described elastic component 5 passes in this appearance hole 24, thereby elastic component 5 is played restriction, and described elastic component 5 can be spring or elastic cord etc.

The utility model is when being in folded state, as shown in Figure 3, first,

second joint

1,2 pivots around articulated elements 4, thereby can make two rod members 3 folding, and this moment, it is outer distolateral that elastic component 5 is around in second joint 2, and be in extended state, thereby store certain elastic energy, at this moment 3 bindings of two rod members must be flicked to prevent it.

When desire is launched two rod members 3, can cooperate shown in Figure 4, unclamp constraint to

rod member

3,1,2 automatically outside rotary expansions under the elastic recovery effect of elastic component 5 of first, second coupled joint, the card platform 22 of second joint, 2 both sides will be along the circular arc periphery rotation of first joint, 1 boss 11, therefore the effect of this circular arc with guiding makes operation smooth and easy; When second joint 2 rotate to be in a straight line with first joint 1 after, elastic component 5 continues pulling two

joints

1,2, be inserted in the bottom of first joint, 1 fluting up to second joint 2, at this moment, the card platform 22 of second joint 2 will be fully with the madial wall of first joint, 1 boss 12 against, two

joints

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