Abstract

The utility model relates to an elasticity stretched folding tent plank, which comprises a bottom rod (1), a top rod (2), a side rod (3), a movable sleeve for the bottom rod (5), and a connection rod (10). A spring (6) is arranged at the hinged part of the segmented rods and the side rod (3). The upper end of the top rod (2) is hinged with a spring position rod (7). The spring position rod (7) is provided with a slant rod movable sleeve (8) and a spring (9). The top rod (2) and the slant rod movable sleeve (8) are hinged with the two ends of the slant rod separately. The utility model has the advantage of reasonable structure design, easy for folding and unfolding, saving on time and labor both, convenient usage and low cost, which is an applicable folding tent plank.

Description

Elastic force opening type folding tent support

The utility model relates to a kind of tent bracket, particularly a kind of open folding tent support of elastic force that utilizes.

At present, tent is people travel in leisure, out on tours, field work provide interim rest place, tent generally is made up of supporting frame and tarpaulin, supporting frame generally is divided into assembling-disassembling and collapsible two kinds, assembling-disassembling need install each unit construction and could use, again the partition of each assembly could transport, carried after the use, the suitable trouble taken a lot of work and time-consuming; Folding supporting frame is an integral body substantially, as long as it is opened then and can use, but because of the general more complicated of its structure, often needs at the same time or separately to a plurality of application of force of opening, and could open passively or folding, handles trouble, and is many with material, relatively heavier.

The purpose of this utility model is to provide a kind of improved elastic force opening type folding tent support for the shortcoming that overcomes above-mentioned prior art, utilize the tension force of spring to open tent bracket rapidly, quickly, time saving and energy saving, simplify the structure, reduce cost, improve convenience.

The purpose of this utility model can realize by following technical measures: this tent bracket has foot lever, push rod, side lever, brace, the foot lever movable sleeve, foot lever has three at least, be provided with side lever between the foot lever with the limit correspondence, side lever is linked to be by segmented poles is hinged, the side lever hinge point is provided with clockwork spring, clockwork spring is connected on the side lever of pin joint both sides, form side lever and open mechanism, push rod is linked to be by segmented poles is hinged, the push rod lower end is hinged on the foot lever, the upper end is hinged with the spring backstay, be equiped with brace movable sleeve and spring on the spring backstay, spring one end withstands the brace movable sleeve, and the brace two ends are hinged on push rod respectively, on the brace movable sleeve, the connecting rod two ends are hinged foot lever movable sleeve respectively, push rod is formed push rod and is opened mechanism.

The side lever of above-mentioned side lever deploying device is by two periods hinged being linked to be of bar, with preferably establishing two side levers between the corresponding foot lever on one side, clockwork spring is connected on the pin joint, one side lever is hinged on the foot lever top, down fold, another side lever is hinged on the foot lever movable sleeve, up folds two sections bar cross-articulation that the both sides pole pair is answered.

Above-mentioned push rod opens the push rod of mechanism by two sections hinged forming of bar, the spring backstay is equipped with two brace movable sleeves and two springs, every a brace movable sleeve is withstood in the spring upper end, and by the scope of activities of pin restraining spring, two brace movable sleeves all have brace hinged, the hinged brace of two brace movable sleeves is hinged with corresponding same push rod top section, section is hinged at the bottom of connecting rod and foot lever movable sleeve and the push rod, and the brace movable sleeve is when lower slider, and push rod folds, when the brace movable sleeve upwards slided, push rod was opened.

After adopting above-mentioned measure, open mechanism spring is housed because of side lever opens mechanism and push rod, has the power of opening, as long as firmly upwards penetrator ram opens the spring backstay of mechanism, spring passes to push rod with power by brace, and push rod drives the foot lever movable sleeve by connecting rod, and the spring that the while side lever opens in the mechanism also passes to power the foot lever movable sleeve, the foot lever movable sleeve moves up, with support rapidly, open quickly; When needing folding, the spring backstay that push rod is opened mechanism applies downward pulling force, the suitable arm of force of connecting rod this moment, and push rod passes to connecting rod with power, and the foot lever movable sleeve is moved down, can be easily with the support folding.

Concrete structure of the present utility model and embodiment are provided by the following drawings.

Fig. 1 is a structural representation of the present utility model.

Below with reference to accompanying drawing the utility model is described in further detail: with reference to Fig. 1, this tent bracket has foot lever [1], push rod [2], side lever [3], brace [4], foot lever movable sleeve [5], foot lever [1] can be established three or many, make Whymper tent or polygonal tent, tent has several angles just to have several foot levers and push rod at least, tent is with between the foot lever [1] on one side two side levers [3] being arranged, every side lever is all by two sections hinged forming of bar, its hinge point is equipped with clockwork spring [6], clockwork spring [6] is connected on the pin joint both sides side levers [3], two sections mutual cross-articulation of bar that the both sides pole pair is answered, one side lever is hinged on foot lever [1] top, down folds, and another side lever is hinged on the foot lever movable sleeve [5], up fold, form side lever and open mechanism; Push rod [2] is by two periods hinged being linked to be of bar, each push rod [2] lower end is hinged on each foot lever [1] upper end of tent respectively, compile on each push rod and be hinged on spring backstay [7] top, two brace movable sleeves [8] and two springs [9] are housed on the spring backstay [7], a brace movable sleeve [8] is withstood in every spring [9] upper end, the scope of activities of available rationed marketing two springs of restriction [9], two brace movable sleeves [9] all have brace [4] hinged, it is hinged that hinged corresponding two braces [4] the same push rod [2] corresponding with it of two brace movable sleeves [8] pushes up section, every push rod [2] is all hinged with two braces, connecting rod [10] one ends are hinged on push rod [2] end section, the other end is hinged on the foot lever movable sleeve [5], and brace movable sleeve [8] is when lower slider, and push rod [2] folds, brace movable sleeve [8] is when upwards sliding, and push rod [2] is opened.

During actual the use, as long as firmly upwards push away spring backstay [7], spring [9] passes to push rod [2] with power by brace [4], push rod [2] drives foot lever movable sleeve [5] by connecting rod [10], the clockwork spring [6] that the while side lever opens in the mechanism also passes to power foot lever movable sleeve [5], foot lever movable sleeve [5] moves up, with support rapidly, open quickly; When needing folding, the spring backstay [7] in the push rod deploying device is applied pulling force downwards, the suitable arm of force of connecting rod [10] this moment, push rod [2] passes to connecting rod [10] with power, and foot lever movable sleeve [5] is moved down, can be easily with the support folding.

Of the present utility model reasonable in design, utilize the tension force effect of spring rapidly, fast to open tent bracket, time saving and energy saving, carry transportation and easy to use, adapt to widely, its structure is simpler, the assembly handling ease, cost of production is lower, is a kind of folding tent support of Nover practical.
