Description

Portable Folding Support Frame and Its Application

technical field

The invention relates to the technical field of brackets, in particular to a portable folding bracket and its application.

Background technique

The folding support frame is popular because of its collapsible size reduction and easy portability. It is widely used in outdoor sunshade devices, drying devices, folding traffic isolation frames, display devices, etc. as support frames. Especially in recent years, with the continuous improvement of people's living standards, more and more people like to go camping on holidays. When camping, people like to build sunshades to avoid the sun and get better rest. Common sunshade devices, such as canopies, folding tents, camping tents, etc., generally include a sunshade cloth and a support frame, and the sunshade cloth is connected to the support frame to play the role of sunshade and wind protection. However, the outdoor sunshade devices of the prior art have the following deficiencies in the actual use process. Specifically, for example, the canopy needs to be supported by two or more support rods, and the support rods are inserted through a plug-in structure. The four corners of the canopy are fixed by ground nails, which leads to a large area for the fixed points of the canopy, and requires high site requirements. It can only be fixed on soft ground such as lawn or sandy soil, and the construction of the canopy is more troublesome. , requires the cooperation of many people, and the operation is inconvenient. Another example is a folding awning, which has four telescopic columns, and an X-shaped folding frame is connected between the tops of adjacent columns. After the bracket of the folding awning is expanded, it can stand on its own, but when the bracket is folded, the top of the folding awning bracket will be closed. The folding frames interfere with each other, and the folding operation is inconvenient. Generally, two people are required to cooperate with the operation to fold the four telescopic columns together. The folding process is inconvenient and laborious; , Folding frames need to be installed between the tops of the columns, so they are cumbersome, not easy to carry, more materials are used, and the cost is high, which cannot meet the relatively lightweight personal or family sunshade needs. Another example is a camping tent. When it is folded, it has a small volume, but when it is used and unfolded, the user needs to support the tent by building a relatively large rigid structure bracket. The process of building the bracket is very troublesome; The latter needs to disassemble the brackets into individual poles, so the operation is time-consuming and laborious, and the user experience is poor. For another example, small tents are often seen in daily life. This small tent generally adopts a flexible frame structure, and cloth is wrapped on the outer periphery of the flexible frame structure to form a small tent. However, the stability of this small tent is relatively poor, and its self-standing property is also relatively weak. During use, it needs to be fixed by a large number of nailed wind ropes, but the small tent cannot be fixed on the hardened ground.

And the supports in the prior art drying device, folding traffic isolation frame, display device, etc. also generally have the defects of complex structure or time-consuming and laborious operation when unfolding and folding.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the above defects of the prior art, provide a simple and light structure, no assembly required by the user, low requirements for the installation site, good structural stability, and labor-saving and fast operation when unfolding or folding. , A portable folding support frame that can be easily completed by a single person.

The technical solution of the present invention is to provide a portable folding support frame with the following structure: it includes

At least two sets of support structures, each adjacent two sets of support structures are connected with a telescopic mechanism, and the telescopic mechanism is used to make the adjacent two sets of support structures relatively fold or expand;

Each group of support structures includes two struts: a first strut and a second strut, and the top ends of the first strut and the second strut are rotatably connected by a hinge point for making the first strut and the second strut the second pole is rotatably folded or unfolded about the rotation axis of the hinge point; and

The first sliding member is slidably fitted on the first support rod along the length direction of the first support rod; each group of the support structures also includes

A connecting rod, the first end of the connecting rod is rotatably connected to the first slider, and the second end of the connecting rod is rotatably connected to the second support rod; the connecting rod is configured such that the first branch When the rod is rotated and folded relative to the second rod, the second end of the connecting rod rotates around its rotation axis, and at the same time, the first end of the connecting rod is linked with the first slider, so that the first slider moves away from the first rod along the length direction of the first rod. Slide in the direction of the hinge point until the first pole and the second pole are completely folded; when the first pole rotates and unfolds relative to the second pole, the second end of the connecting rod rotates in the opposite direction around its axis of rotation, and the connecting rod The first end of the first sliding part is linked with the first sliding part, so that the first sliding part slides along the length direction of the first support rod in a direction close to the hinge point until the first support rod and the second support rod are fully unfolded.

After adopting the above structure, compared with the prior art, a portable folding support frame of the present invention has the following advantages: when the portable folding support frame is in use, only two adjacent support structures need to be unfolded and the first support structure The supporting rod and the second supporting rod can be rotated and opened around their hinge points to make the support frame unfold, and can stand on its own, with good standing stability and no need to be fixed to the ground. It has low requirements for the installation site and a wide range of applications; especially in When the support structure is unfolded or folded, because of the linkage relationship between the connecting rod and the first sliding member and the connecting rod and the first and second rods, only the first or second rod needs to be rotated, or the first sliding The bracket structure can be unfolded or folded by sliding parts or connecting rod rotation. Its structure is simple, light, and easy to carry, and it is easy to operate and labor-saving. A single person can easily complete the unfolding or folding of the bracket structure, satisfying the user's rapid unfolding or folding. needs, and the user experience is good; moreover, after the support structure is unfolded, the first support rod, the second support rod and the connecting rod form an A-shaped standing structure, that is, the first support rod, the second support rod The two struts and the connecting rod form a stable triangular standing structure, so that it has good standing stability and good windproof performance.
