Description

Tent frame with reinforced structure

technical field

The utility model relates to a tent frame, in particular to a tent frame with a reinforcing structure which can prop up and unfold a canopy and has better structural strength.

Background technique

In the prior art, there are many types and basic structures of tents. Among them, the tent skeleton 1 shown in Fig. 1 can prop up an unfolded canopy 10, and includes several main support units 11 (only two are shown in Fig. 1 ) spaced front and rear, and several link units 12 extending forward and backward and connecting adjacent main support units 11 , and several brace reinforcement mechanisms 13 between adjacent main brace units 11 .

Each main support unit 11 has two left and right spaced foot bars 111, two first joints 112 installed on the top ends of the foot bars 111, a second joint 113, and two respectively inserted in adjacent first joints. And the top strut 114 between the second joints 112 and 113. Wherein the first connector 112 has a cannula portion 115 extending toward the second connector 113 . The second joint 113 has two inserting tube parts 116 respectively extending toward the first joint 112, and the connecting rod unit 12 has three branches inserted in the adjacent first joint 112 or the adjacent second joint 113. The connecting rod 121 between. The top support rod 114 is movably inserted between the insertion tube portions 115 , 116 of the first and second connectors 112 , 113 , and has a through hole 117 roughly in the middle.

In the past, the tent frame 1 was installed with a tension reinforcement mechanism 13 to strengthen the structural strength between the adjacent main support units 11, so as to avoid concentrated pressure of rainwater or ice and snow on the adjacent connecting rods 121 and top support rods 114. In the surrounding area, cause the canopy cover 10 to rupture thereby, or crush the entire tent skeleton 1. Each brace reinforcement mechanism 13 has two hooks 131 that respectively pass through the perforations 117 of adjacent top braces 114, a screw seat 132 with a reverse threaded hole, and two hooks that are respectively hooked to one of them. The piece 131 is hooked and screwed onto the threaded piece 133 on the screw seat 132 . The hooking member 131 can be tightened or loosened by turning the screw seat 132 , so as to achieve the purpose of strengthening the tent frame 1 by using the brace reinforcement mechanism 13 .

In the past, in order to improve the defect that the distance between adjacent connecting rods 121 is too large for ice and snow to easily collapse here, the tent frame 1 mainly installs a brace reinforcement mechanism 13 between adjacent top brace rods 114. Though the mechanism 13 can play the function of auxiliary reinforcement, in order to install the reinforcement mechanism 13 for tensioning, it is necessary to drill a perforation 117 on the top strut 114 . The aforementioned perforations 117 will weaken the structural strength of the top braces 114. Therefore, when the canopy cover 10 carries a large amount of rainwater or ice and snow, the entire tent frame 10 is easily bent and deformed from the place where the perforations 117 are provided. Because the aforementioned top braces 114 The two rod ends of the first and second joints 112, 113 are respectively inserted into the insertion tube parts 115, 116 in a movable manner. Therefore, when the top strut 114 is seriously deformed, the rod end of the top strut 114 will be It may be disengaged from the first and second joints 112 and 113 that are movably inserted, causing the entire tent frame 1 to collapse.
