Abstract

The utility model relates to a spacing structure of a top pole of a tent, wherein a tent top of the tent is composed of the top pole and an auxiliary pole support, the top pole is composed of a first pole support and a second pole support, the end parts of the first pole support and the second pole support are pivoted, one end of a first pole support is pivoted on a fixed seat on the top of the tent, the other end of the second pole support is pivoted on an upright post of a tent rack, the auxiliary pole support is composed of a first auxiliary pole and a second auxiliary pole, the end parts of the first auxiliary pole and the second auxiliary pole are pivoted, one end part of the first auxiliary pole is pivoted on a position of the first pole support, the position is near the middle part of the first pole support, the second auxiliary pole is pivoted with the middle part of the second pole support together, the other end of the second auxiliary rod is pivoted on the upright post of a tent rack and a spacing block is convexly extended out between the first pole support and the first auxiliary pole or between the second pole support and the second auxiliary pole. The spacing block can prevent the small values of intersection angles between every pole support and auxiliary poles. When the two pole supports are pushed upwards, the spacing block plays a limiting function for the move of the pole supports, and thus, the support state of the upright post of the tent can be ensured and the collapse of the tent can be prevented.

Description

Tent push rod position limiting structure

Technical field

The utility model is about a kind of folding tent, is meant a kind of tent push rod position limiting structure especially.

Background technology

General relatively large tent, the support strength of its paulin top pole group is had relatively high expectations, the artificial support strength that improves the tent push rod of this case design, the ad hoc tent push rod structure as shown in Figure 1, 2 of having counted, its application number is 200420091619.

It mainly is made of push rod 1 and auxiliary pole 2.

Push rod 1 is to be articulated and to be constituted by length identical approximately first pole 11, second pole, 12 head and the tail, forms a pivoting point A, and wherein an end of first pole 11 is to be articulated on the paulin top Connection Block 3, and the other end of second pole 12 is to be articulated on the paulin frame column 4;

Auxiliary pole 2 is to be articulated by the first auxilliary bar 21 and second auxilliary bar 22 head and the tail to constitute, form pivoting point B, one end of the first auxilliary bar 21 is the nearly medium positions that are articulated in above-mentioned first pole 11, form pivoting point C, and the nearly medium position of the second auxilliary bar 22 and the nearly medium position of above-mentioned second pole 12 are to be articulated, form pivoting point D, the other end of the second auxilliary bar 22 is to be articulated on the paulin frame column 4.

Cooperate Fig. 2, shown in 3, when launching tent, when upwards promoting sliding seat 42, two joint poles 11, the auxilliary bar 21 of 12 and two joints, 22 are the convergence state, therefore the angle of second pole 12 and second auxilliary bar 22 formation is more and more little, other four pivoting point A, B, C, D surrounds a quadrangle (this sentences parallelogram is example), angle between the second auxilliary bar 22 and the first auxilliary bar 21 is more and more big, therefore the first auxilliary bar 21 just has a power that upwards lifts to first pole 11, second auxilliary 22 pairs second poles 12 of bar have a thrust that makes progress simultaneously, so just play one and support the effect of paulin top pole.When folding, spur sliding seat 42 downwards, because the pivot joint of each position relation, two

joint poles

11,12 can be concentrated and be drawn close, and the

auxilliary bar

21,22 of two joints also can be concentrated and draw close simultaneously, can guarantee so that tent is drawn close smoothly to fold, and realize folding function.

Force in two

joint poles

11,12 respectively just because of the

auxilliary bar

21,22 of two joints, the integrated support dynamics of the tent push rod of this structure is evenly distributed, and support degree is strong.

But, above-mentioned tent push rod also has needs to replenish improvements, that is, because the pivoting point A of two

joint poles

11,12 can occupy certain position in tent, if as running into the higher people of height, straighten one's back in tent when raising one's hand, when shifting the pivoting point A of two

poles

11,12 because of carelessness onto, pivoting point A is stressed, two

joint poles

11,12 have the trend of flattening, meanwhile can drive auxilliary bar 22 pulling tent columns 4 has a trend that moves in paulin, therefore exert oneself when excessive, and tent stand easily collapses.

The utility model content

The purpose of this utility model provides a kind of tent push rod position limiting structure, and it can be in case two joint poles be flattening trend to guarantee the holding state of tent column.

For achieving the above object, solution of the present utility model is: a kind of tent push rod position limiting structure, wherein tent Peng Ding is made of push rod and auxiliary pole, push rod is to be made of first, second pole that two joint ends are articulated, wherein an end of first pole is to be articulated on the holder of tent top, and the other end of second pole is to be articulated on the paulin frame column; And auxiliary pole also is to be made of first, second auxilliary bar that two joint ends are articulated, the nearly medium position that one end of the first auxilliary bar is articulated in first pole, the middle part of the second auxilliary bar and second pole is articulated, the other end of the second auxilliary bar is to be articulated on the paulin frame column, it is characterized in that: protruding out a limited block between first pole and the first auxilliary bar or between second pole and the second auxilliary bar.

The other end of described second pole is to be articulated on the sliding seat of paulin frame column, and then the other end of the second auxilliary bar is to be articulated on the holder at paulin frame column top.

Described limited block is to be fixed near on first pole of first pole and the first auxilliary bar pivot connecting point position or on the first auxilliary bar.

Described limited block is to be fixed near on second pole of second pole and the second auxilliary bar pivot connecting point position or on the second auxilliary bar.

After adopting such scheme, tent push rod of the present utility model protrudes out a limited block in the angle position of each pole and auxilliary bar, this limited block can prevent that the angle of each pole and auxilliary bar is too small, then when two joint poles are subjected to upwards thrust, this limited block has moved a restriction to pole, therefore can guarantee the holding state of tent column, prevent that the tent stand from collapsing.

The specific embodiment

Cooperate shown in Fig. 1,2 as Fig. 3,4,5, the preceding narration that coexists of the support push rod structure of tent of the present utility model is not given unnecessary details at this, and key of the present utility model is:

Between the first auxilliary bar 21 and first pole 11, near the pivoting point C position of the first auxilliary bar 21 and first pole 11, be provided with a limited block 5 simultaneously, this limited block 5 is to be fixed on the first auxilliary bar 21 or first pole 11, and convexedly stretches in (see figure 4) outside each rod member; As shown in Figure 5, this limited block 5 also can be located between the second auxilliary bar 22 and second pole 12, promptly near second position of assisting the pivoting point D of the bar 22 and second pole 12, limited block 5 is to be fixed on the second auxilliary bar 22 or second pole 12, and convexedly stretches in outside each rod member.

Because the position protrudes out a limited block 5 between the angle of each pole and each auxilliary bar, the angle that this limited block 5 can prevent each pole and auxilliary bar is too small, then when two

joint poles

11,12 are subjected to upwards thrust, 5 pairs of poles of this

limited block

11,12 have been moved a restriction, therefore can guarantee the holding state of tent column 4, prevent that the tent stand from collapsing.
