Detailed description of the invention

Embodiment one

Refer to Fig. 1 to Fig. 9, a kind of tent rack, including the first bracing frame 10, this first bracing frame 10 includes two first Bar 11 and an a connecting seat 12, this two first pole 11 first end is rotatably connected so that two by a connecting seat 12 First pole 11 can rotate between folding position and expanded position, in the middle part of this each first pole 11 on be all rotatably connected to one Second pole 21, this first pole 11 and the second pole 21 coordinate composition shears fork 20, and this two first pole 11 is in expansion position The first bracing frame 10 put overarches frame and two second poles 21 are isolated, and this isolation is arranged as parallel, and this is parallel such as parallel cloth Put, this two second pole 21 first unsettled layout of end.Wherein: rotation and the rotation of shears fork between two first poles are the most mutual Interfering, shears fork expanded angle is not limited by the first bracing frame expanded angle, can arbitrarily launch shears fork angle.Preferably, this A connecting seat 12 is provided with the holding structure for keeping two first poles 11 to be in the deployed, and this holding structure is such as locking machine Structure 123, two first poles that locking mechanism interlocking is in the deployed, then two first poles are maintained at expanded position, and pine oil is locked Fixed structure, then can rotate two first poles.This first pole and the second pole such as optional elastic fiber bar or rigid bar are rigid The rigid bar of bar such as metal or the rigid bar of plastics.

This first pole 11 and the non-parallel setting of pivot center of the pivot center of the second pole 21 and two first poles 11, Among the present embodiment one, the pivot center vertical of these two first poles 11 being in the deployed is arranged, so that two first Bar horizontally rotates setting, two first poles can such as can reach 180 degree or cross 180 degree of states, with energy when expanded position Play the effect of self-locking.

Refer to Fig. 2, among the present embodiment one, this connecting seat is cradle head, and it includes that one is fixed in one first First union joint 121 of pole 11 first end and one is fixed in the second union joint 122 of another the first pole 11 first end, and this is years old One union joint 121 and the second union joint 122 are rotationally connected, and make two first poles be rotationally connected, this first union joint 121 and second Union joint 122 rotation connection structure is such as: the first union joint 121 sets a link slot 124, and this second union joint 122 sets lug 125, This lug 125 inserts in link slot 124, and another pivotally connected lug and the link slot of arranging is so that the two composition is rotationally connected.This is years old A connecting seat is CN103669992A as disclosed in Chinese patent is according to storehouse.

This first pole 11 second end, the second pole 21 second end all pass through the second connection seat 30 and are rotatably connected to foot lever 40, when a kind of tent rack launches and uses, foot lever 40 is supported on ground level.This second connection seat 30 is provided with for keeping pole 11 and the holding structure that is in the deployed of foot lever 40, pole 21 and foot lever 40, this holding structure is as locking mechanism, and this is second years old Connect seat 30 CN103669992A as disclosed in Chinese patent is according to storehouse.This foot lever 40 is as expansion link, and the interior bar of this expansion link leads to Crossing the second connection seat 30 and connect the first pole, this outer bar is connected to outside interior bar, separately sets bar and outer bar in the second locking mechanism connects So that being maintained at elongation both during elongation, can slide both during pine oil, or, it is articulated in one including by another the second connection seat 30 The first foot lever risen and the second foot lever.This foot lever 40 is as may select elastic fiber bar or the rigid bar of metal or the rigid bar of plastics.

Refer to Fig. 3, be admittedly arranged with first in the middle part of this first pole 11 and admittedly overlap 211, solid sheathed in the middle part of this second pole 21 Have second admittedly to overlap 212, by pivot through first admittedly set 211 and second set admittedly 212 the two is linked together, so that the two structure One-tenth is rotationally connected, so that the first pole and the second pole constitute shears fork.

Fig. 1 to Fig. 9, depicts a kind of tent rack and illustrates from the step being expanded to folding, but do not limit with this, according to need , each user carries out folding also dependent on the custom of oneself by different step, and this first pole and foot lever rotate upwardly and downwardly the exhibition of realization Open or fold, as both the first pole and foot lever are launched away from rotating realization from top to down, and this two first pole horizontally rotates Realizing launching or folding, one rotates upwardly and downwardly, and another one horizontally rotates, the two rotation direction difference 90.Figure 10 and Figure 11 illustrates, A kind of structural representation of the tent of tent rack application example.This tarpaulin 70 is articulated under a kind of tent rack, and due to two Second pole the first end is unsettled, therefore at this can the doorway 71 of just corresponding tarpaulin 70, two second pole the first ends connect tarpaulins Corner on the two of the doorway of 70.And, it is achieved a kind of tent frame rod and the fully integrated setting of tent cloth, open folding the most square The quickest.

Embodiment two

It is with embodiment one difference: refer to Figure 12, turning of these two first poles 11 being in the deployed Moving axis line is horizontally disposed.This two first pole rotates upwardly and downwardly realization and launches or fold, as two first poles rotate reality from bottom to top Now launch.This first pole and foot lever rotate upwardly and downwardly realization to launch or folds, if both the first pole and foot lever are away from from upper Down rotate and realize launching.The two rotation direction difference 180.

Embodiment three

It is with embodiment two difference: refer to Figure 13, and this two first pole rotates upwardly and downwardly realization and launches or folding Folded, rotate realization such as two first poles from bottom to top and launch.This first pole and foot lever rotate upwardly and downwardly realization to launch or folds, as Both first pole and foot lever are launched away from rotating realization from bottom to top.The two rotation direction is in the same direction.

Embodiment four

It is with embodiment one difference: refer to Figure 14, and this one tent rack also includes the second bracing frame 50, should Second bracing frame 50 includes that the 3rd pole the 51, the 3rd connects seat 52 and the second above-mentioned pole 21, the 3rd pole 51 first end And second pole 21 first end by the 3rd connection seat 52 be rotatably connected and can turn between expanded position and folding position Dynamic, the 3rd pole 51 is rotatably connected to the 4th pole 61, the 3rd pole 51 and the 4th pole 61 coordinate composition shears fork 60, the second bracing frame 50 that the 3rd pole 51 and the second pole 21 are in the deployed overarches frame and the first pole 11 and Four poles 61 are isolated, the 4th pole 61 first unsettled layout of end.Among the present embodiment, only set second bracing frame, root According to needs, also can arrange another second bracing frame, this second bracing frame coordinates another the second pole.

This first pole 11 second end, the second pole 21 second end, the 3rd pole 51 second end and the 4th pole 61 second End all passes through the second connection seat 30 and is rotatably connected to foot lever 40.

The above, only this utility model preferred embodiment, therefore can not limit what this utility model was implemented according to this Scope, the equivalence change i.e. made according to this utility model the scope of the claims and description and modification, all should still belong to this practicality new In the range of type contains.
