Abstract

A hack lever of a marquee is supported by posts (1), crossed support shaft groups (2) are pivoted between the top of the adjacent posts, and a knighthead group (3) is provided on the whole hack lever. In which, the knighthead group (3) consists of a top centre-pole (31) and knightheads (32), the knighthead (32) is formed by pivoting three shafts (321,322,323) in turn, and the near end of the inside shaft (321) is pivoted to the fixed seat (33) on the toe of the top centre-pole (31), and the farend of the outside shaft (323) is radially pivoted to the top of the post (1); in addition, a slipper block (34) is provided on the top centre-pole(31), a first support bar (35) is pivoted between the slipper block and the inside shaft (321) and a second support bar (36) is pivoted between the farend of the first support bar (35) and the middle shaft (322) of the three shafts.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tent, and more particularly to a large tent pole. BACKGROUND OF THE INVENTION In the prior art, a common tent pole structure is shown in FIG. 1 , and the pole is supported by a plurality of poles 1 ′, and a plurality of cross support poles are pivotally connected between upper ends of two adjacent poles 1 ′. 2' (Set three sets of cross support rods 2' as shown in the figure), there is a top support rod set 3' at the top of the entire pole, and then a tarpaulin is placed on the outer pole of the rack to form a complete tent. . The top support bar set 3' is generally constructed by a plurality of struts supporting each other, and each struts are generally composed of two mutually foldable members, thereby facilitating the folding of the overall tent.

However, for larger tents, for example, the side cross-support rod set 2' is set to four sets, at this time, the distance between each pole 1' is elongated, and the top support rod group 3' each pole of the pole The length of the piece must also be relatively long, so that the support of the strut is greatly reduced, and the folding volume of the tent is also increased. SUMMARY OF THE INVENTION It is an object of the present invention to provide a large tent pole that reduces the folding volume and provides a stable support for the top support bar set.

To achieve the above object, the technical solution of the present invention is:

a large tent frame body supported by a plurality of poles, a plurality of cross support rod groups are pivotally connected between the upper ends of the adjacent two poles, and a top support rod group is further disposed on the top of the entire pole; the top support The rod set mainly comprises a top middle rod and a plurality of struts, the struts being composed of three mutually pivoting rod members, wherein the inner end of the inner rod member of the three rod members is pivotally connected to the fixing seat at the lower end of the top middle rod, and The outer end of the outer rod is pivotally connected to the top end of each pole; in addition, a sliding seat is further disposed on the top middle rod, and the sliding seat is pivotally connected with the inner rod of each strut. The first support rod has a second support rod pivotally connected between the outer end end of the first support rod and the middle rod member of the three rod members.

After adopting the above scheme, since the first and second support bars are provided in the present invention, the extended struts can be supported in the middle, so that the purpose of stable support can be achieved. In addition, since each of the struts is pivotally connected by three rods, the length of each rod can be reduced, so that when the tent is folded, the volume after folding can be greatly reduced, and the volume and middle after folding are made. Small tents have the same folding volume. DRAWINGS 1 is a schematic structural view of a conventional tent pole;

Figure 2 is a schematic view of the structure of the present invention;

Figure 3 is a half-receiving diagram of the present invention;

Figure 4 is a collapsed state diagram of the present invention. As shown in FIG. 2 , the tent pole of the present invention is supported by a plurality of poles 1 , and a plurality of intersecting support rods 2 are pivotally connected between upper ends of two adjacent poles 1 (this embodiment is provided with Four sets of cross-supporting rods, belonging to the large tents, are provided with a top support rod set 3 at the top of the entire pole, and then a tarpaulin is placed on the outer cover of the rack to form a complete tent.

The difference between the present invention is as follows: The top support bar set 3 mainly includes a top middle bar 31 and a plurality of brace bars 32. The brace bar 32 is composed of three mutually pivotally connected rod members (ie, the inner rod member 321 and the middle rod rod 322). And the outer rod member 323) is configured, wherein: the inner end of the inner rod member 321 is pivotally connected to the fixing seat 33 at the lower end of the top middle rod 31, and the outer end of the outer rod member 323 is radially pivotally connected to each of the rods 1 Top; in addition, a sliding seat is also slid on the top middle rod 31

A first support rod 35 is pivotally connected to the inner rod member 321 of the support rod 32. The first support rod 35 is further pivotally connected to the middle rod member 322. A support rod 36 is used to prop up the middle rod member 322 to support the middle portion of each of the stays 32.

In this way, after the entire tent pole is propped up, the first and second support rods are provided.

35, 36, which can support the middle of the elongated struts 32, so as to achieve the purpose of stable support.

When the large tent pole is folded, as shown in FIGS. 3 and 4, the fixing seat 33 at the bottom of the rod 31 in the top of the top is pulled down, so that the top middle rod 31 moves down the sliding seat 34, so that the rods are mutually moved. Inwardly, since the struts 32 are pivotally connected by the three rods, the length of each rod can be reduced, thereby greatly reducing the volume of the large tent after folding, so that it intersects with two or three sets. The tents of the support bar group 2 have the same folding volume.
