Description

Technical Field

[0001] The utility model relates to a tent, and more particularly to a tent pole. Background Art

[0002] As an outdoor leisure product, tents are widely used in various occasions. Common tent brackets are generally composed of multiple groups of vertical poles connected to top poles. The top poles form the top support, and the adjacent vertical poles are connected to the retractable side brackets. The tent roof includes multiple top poles, the inner ends of which are respectively pivoted to a top connector located in the center of the tent. Since the top poles have a certain length and a certain height when unfolded, when the tent is unfolded, the unfolding process of each top pole may not be smoothly unfolded synchronously, and a certain amount of manpower is required to support and assist. In addition, after the top poles of the tent are unfolded, the top ends are only connected by a top connector, which is easy to deform or fold inward after being subjected to external forces (such as strong winds or water accumulation on the tent roof). The support of the top of the tent is unstable, affecting the normal use of the tent. This case arises from this. Utility Model Content

The top pole 2 may include an inner rod 21 and an outer rod 22 pivoted in the middle, and the inner rod 21 and the outer rod 22 can be unfolded and supported upward or folded downward in the middle, so as to cooperate with the unfolding support to form the top surface of the tent and the overall folding of the tent.

[0030] In the utility model, in order to enable the tent top support of the tent frame pole to cooperate with a push-up action when unfolding, and to make each top pole more stable after unfolding, a push-up mechanism is provided at the concentrated inner end of each top pole, and the push-up mechanism includes a top reinforcing rod 51 connected to one side close to the inner end of each top pole 1, the inner end of the top reinforcing rod 51 is pivoted to a lower connecting member 52, and the lower connecting member 52 moves upward to the bottom of the top connecting member 3 as the top pole 2 unfolds upward. After the top pole 2 is unfolded, the top reinforcing rod 51 is tilted and supported with the inner end higher and the outer end lower, and is limitedly supported below the top of the tent center, thereby pushing the top of the tent to open and stably support. Specifically, the outer end of the top reinforcing rod 51 can be pivoted to the middle or inner side of the inner pole 21, and the angle between the top reinforcing rod 51 and the vertical line of the ground increases to an obtuse angle during the upward unfolding of the inner pole 21, and can not continue to move upward after the top pole 2 is unfolded, forming a limited support. A limiting member may be provided in each top reinforcing rod 51 to limit the inner end of the top reinforcing rod 51 from further rotating upward after the top rod 2 is unfolded.

[0031] The limiting member can be in various forms, as long as it can limit the inner end of the top reinforcing rod 51 from further rotating upward after the top rod 2 is unfolded, so as to form an inclined top-supporting and stable supporting state. Figure 2 , Figure 3 The first embodiment of the push mechanism is shown in the figure. The limiting member in this embodiment is a lower stopper 521 provided at the lower part of the lower connecting member 52 to stop the inner end of the top reinforcing rod 51 from rotating. The lower connecting member 52 is provided with a plurality of pivoting grooves 520 corresponding to the number of top reinforcing rods for the inner end of the top reinforcing rod 51 to be pivoted. The lower stopper 521 is located at the bottom of the lower connecting member 52 and is stopped below each pivoting groove 520. The lower stopper 521 can limit the top reinforcing rod 51 from continuing to rotate upward after being unfolded. After the top rod is pushed to unfold, it also reaches a supporting balance state. Each top reinforcing rod 51 can form a stable support below the inner rod 21 of the top rod.

[0032] Combination Figure 8 , Fig. 9 : is a structural schematic diagram of the second embodiment of the push mechanism, the difference between this embodiment and the first embodiment is that, in this embodiment, the limiting member is an upper stopper 522 provided on the upper part of the lower connecting member, the lower connecting member 52 is provided with a plurality of pivoting grooves 520 for the inner end of the top reinforcing rod to be pivoted, the upper stopper 522 is located at the top of the lower connecting member 52 and stops above the inner end of each pivoting groove 520. The upper stopper 522 can also limit the top reinforcing rod 51 from continuing to rotate upward after being unfolded, so that the top reinforcing rod can reach a stable supporting state after being unfolded upward.

[0033] Combination Fig.10 , Fig.11 : is a schematic diagram of the structure of the third embodiment of the push mechanism. In this embodiment, the limiter is a stopper 53 installed on the inner side of the push rod 2 near the inner end. The stopper 53 is located on the inner side of the pivot point between the outer end of the top reinforcing rod 51 and the push rod 2. By adding a stopper 53 to the outer end of each top reinforcing rod 51, the stopper 53 can press and block the outer end of the top reinforcing rod 51, thereby limiting the inner end of the top reinforcing rod 52 from continuing to rotate upward. The outer peripheral surface of the stopper 53 can form an arc. The stopper 53 in this embodiment forms a pulley, and the top reinforcing rod 5 is then pushed into the pulley.

[0034] Combination Fig.12 , Fig.13 Schematic diagram of the structure of the fourth embodiment of the push mechanism. In this embodiment, the limiter is an upper stopper 54 provided in the upper part of the top reinforcing rod 51 near the outer end. The upper stopper 54 can be pressed against the bottom of the top reinforcing rod 2, thereby limiting the inner end of the top reinforcing rod 51 from continuing to rotate upward. In this embodiment, a sleeve 540 can be fixedly installed in the top reinforcing rod 51 near the outer end. The upper stopper 54 forms a U-shaped groove convexly provided at the upper end of the sleeve 540. After the top reinforcing rod 2 is deployed, it can be placed or clamped into the upper stopper 54 to limit the position, so that the top reinforcing rod 51 is pressed, thereby limiting the top reinforcing rod 51 from continuing to rotate upward after being deployed, so that the top reinforcing rod reaches a stable support state after being deployed upward.

[0035] When the tent pole of the utility model is used, it is combined with Figures 1 to 7 As shown, when the tent is unfolded, each top pole 2 of the tent is unfolded along with the unfolding of the vertical pole 1 and the side pole group 4, and the inner pole 21 of the top pole 2 is unfolded upward, as shown in FIG. Figure 6 as well as Figure 4As shown, at this time, the lower connecting member 52 in the push mechanism moves upward to the bottom of the top connecting member 3 as the top rod 2 unfolds upward, and the top reinforcing rod 51 is supported with the inner end higher and the outer end lower after the top rod 2 unfolds, and is limitedly supported below the top of the tent center, thereby pushing the top of the tent to open and stably support it, and it can not continue to move upward after the top rod 2 unfolds, forming a limited support. The top reinforcing rod 51 and the lower connecting member 52 can assist the top rod 2 in supporting the unfolding, and can improve the stability of the top of the tent. On the contrary, when it is necessary to fold the tent, the vertical poles 1 are folded back together, the top rods 2 are folded down in the middle, the lower connecting member 52 moves downward, and the top reinforcing rods 51 are also folded down, and finally folded against the inner side of the folded top rod, and can be unfolded and folded synchronously with the unfolding and folding of the tent top rod, without affecting the folding action and folding volume of the tent, and it is easy to install and use.
