The umbrella formula supports the canopy support frame of collecting account automatically

Technical field

The utility model relates to a kind of tent, refers to that especially a kind of umbrella formula supports the canopy support frame of collecting account automatically.

Background technology

Tent is the equipment commonly used of climbing the mountain, going fishing, camping, and its kind is varied.Can be divided into according to its shape: A type, semi-circular, house type, cavern type etc.; Folding or expansion mode according to tent can be divided into: be traditional collapsible shelter of support and be the umbrella formula break camp of support with the umbellate form skeleton with manual basic framework.

For umbrella formula break camp, it is that manner of execution with similar Folding umbrella folds or launch tent.Common structure as shown in Figure 1, the central top of this tent is provided with a push rod connector 10, the radial bar group 40 that is provided with on this push rod connector 10, this bar group 40 is made up of some joints (being generally three joints) rod member, then linked to each other by the rod member connector between each rod member, so that folding, tent cloth then is fixed on each bar group 40, the bottom of each bar group 40 then is fastened on the staple of tent cloth bottom periphery, thereby can prop up tent.The downside of described push rod connector 10 is provided with rod in, and rod is provided with a sliding part 20 in this, the radial support bar 30 that is provided with of these sliding part 20 corresponding each bar group 40 quantity, and this support bar 30 is supporting the first segment rod member of bar group 40.Be provided with a spring 50 between described push rod connector 10 and the sliding part 20, this spring 50 is in compressive state when tent is folding, and when tent launched, the elastic-restoring force of this spring 50 can make each bar group 40 of tent strut automatically.

From the structure of above-mentioned umbrella formula break camp as can be seen, there is following defective in it:

1, described spring 50 is after the release elastic energy is launched tent, to be in free state, at this moment, each support bar 30 is in level, and the support bar 30 of level also can't be propped up each bar group 40, therefore must artificially sliding part 20 be pulled down again, support bar 30 outer ends are inclined upwardly, so that prop up bar group 40, tent can be strutted fully but just must carry out two steps like this, inconvenience operates.

2, as once being strutted, tent puts in place, then after tent launched, described spring 50 must have certain decrement, and this decrement will continue to press down support bar 30, support bar 30 outer ends are inclined upwardly with the first segment of support bar group 40, thereby reach the purpose of once propping up tent; Yet reach this decrement, then must one fastening devices be set at sliding part 20 places, so that it is sliding part 20 is fixing in order to compression spring 50, but because the dynamics that struts of tent is bigger, requirement of strength to fastening devices is just higher, and frequent use wearing and tearing also often make fastening devices damage, and cause the support of support bar 30 unreliable, thereby tent is subsided.

3, owing to outside described spring 50 is exposed to, be easy to be corroded by rainwater, the spring that is corroded then easily gets rusty, and rusty stain is then easily done flower to the cloth of tent, not only influences outward appearance, the more serious life-span that also can influence tent.

4, sliding part 20 is generally and freely is placed on the middle rod, it can rotate on middle rod arbitrarily, though when tent is propped up, it will be subjected to the effect of support bar 30 and can't rotate arbitrarily, but tent is after gathering, usually the tent yardage roll to be enclosed in the support place, so just will cause push rod connector 10 relative sliding parts 20 to rotate to an angle, and owing to support bar 30 outer ends link to each other with bar group 40 on the other side, thereby support bar 30 is reversed, support bar 30 is in long-term twisting resistance effect, very easily fracture at the root that is articulated with sliding part 20, and influence used.
