Tent frame bar structure without side bar group

Abstract

The invention discloses a tent frame rod structure without a side bar group. The tent frame bar structure comprises a vertical bar, a tent top bracket and a support top bar group, wherein the vertical bar is provided with a fixed base and a sliding base; the tent top bracket comprises four connecting rod groups which are articulated with one another end to end and are unfolded to form a square shape and four groups of hinge points are formed; each connecting rod group comprises two groups of articulated connecting rod units; each connecting rod unit comprises two connecting rods which are mutually articulated and can be unfolded to form an X shape; each group of hinge points of the four articulated connecting rod groups form hinge points and lower hinge points; the hinge points of the two groups of articulated connecting rod units are upper central hinge points and lower central hinge points; the support top rod groups comprisesfour groups of connecting rod units, each group of connecting rod units corresponds to one group of hinge points of the tent top bracket, and each connecting rod unit of the support top rod group comprises two connecting rods which are mutually articulated and can be unfolded to form an X shape.

Description

technical field [0001] The invention relates to a tent, in particular to a tent pole structure without side pole groups. Background technique [0002] Existing tent pole structure comprises four upright poles and canopy support, and upright pole is telescopic pole, and upright pole and canopy support all directly contact with tent cloth and form support to tent cloth, between canopy support and every upright pole Both are connected with a set of supporting push rods, and a set of side push rods is connected between every two adjacent vertical rods, and an oblique strut is also connected between each vertical rod and each set of side push rod groups connected to the vertical rod Because the tents are all used outdoors, their structure must be easy to fold and carry. Therefore, the side push rod group connecting the top of the two upright rods of the tent includes at least two rod members and pivot joints that are pivotally connected to each other. [0003] Above-mentioned ex...

AI Technical Summary

Problems solved by technology

[0004] First of all, as a kind of outdoor leisure product, the tent is required to be portable, and the tent with the above structure is supported by multiple sets of rods. There are many rods, and it is difficult and time-consuming to support it. Manufacturing cost, but not light enough when folded

[0005] Secondly, the tent cloth is easy to form pits under the action of gravity, especially when the high-top tent is used in rainy days, the middle position of the tent cloth between the center stem and the side push rod group is more likely to be concave under the impact of rainwater to form water accumulation, which will aggravate The load of the tent frame is also easy to be splashed by accumulated water when the tent is disassembled, which affects the service life of the tent

[0006] Furthermore, since the side push rod group is pivotally connected by at least two rods, after the above-mentioned tent has accumulated water, the force points of the side push rod group will all move to the pivot point of the two rods, that is, the pivot joint must bear the tension of the tent. The weight of the cloth and the accumulated water, so the hinge is very easy to break, which affects the service life of the tent. This is also the part with a high repair rate of the current tent, and it is urgent to improve
