Technical Field

The invention relates to the technical field of folding frames, in particular to a novel folding frame.

Background

Along with the continuous improvement of the living standard of people, people in cities have increasingly long requirements on folding frames, no matter pet houses, travel tents or dormitory clothes hangers, the folding frames are basically coated by frames and external covering cloth, the traditional integral frame structure cannot be disassembled, the occupied space is large, and the problems of production, transportation and storage are solved and the corresponding packaging materials are wasted; the second frame structure fixed after being assembled is difficult to disassemble, still occupies a large space when not used, and has high transportation cost; the third frame structure which can be folded and has a fixed length-width ratio can not change the ratio along with the requirements of people, is equal in length and only can have a fixed ratio, has a single style, and can not meet the requirements of users.

Disclosure of Invention

The invention aims to provide a folding frame which can be produced according to the requirements of consumers and can make the whole length-width ratio different according to different types of positions of hinged parts so as to solve the problem of fixed ratio of the existing folding frame.

In order to achieve the technical purpose and achieve the technical effects, the invention discloses a novel folding frame, which comprises a support frame and a locking piece, wherein the support frame is in an unfolded state and a folded state, and the locking piece is used for locking the support frame in the unfolded state, and is characterized in that the support frame comprises: the support frame is composed of four support rods, a movable connecting assembly, a fixed connecting piece and a swing rod mechanism which are arranged in parallel and have the same shape and size, and the support rods are provided with first locking holes in which the locking pieces are slidably arranged; the movable connecting assembly moves along the length direction of the supporting rod; the fixed connecting piece comprises a first connecting piece for connecting the supporting rod and the swing rod mechanism and a second connecting piece for connecting the movable connecting assembly and the swing rod mechanism; the swing rod mechanism comprises at least one group of first swing rod assemblies and at least two groups of second swing rod assemblies, the first swing rod assemblies are composed of two first swing rods with the same shape and size, the two first swing rods are hinged into a whole through the middle position, the second swing rod assemblies are composed of two second swing rods with the same shape and size, and the hinged position of the two second swing rods is a non-central position; when the support frames are in a folded state, the support rods are folded towards the center, and the swing rod mechanism is folded between two adjacent support rods.

In the scheme, the non-central design of the hinged part of the second swing rod can produce the folding frames with different length-width ratios of the whole body according to different positions of the hinged part according to the requirements of consumers, and the folding frames are not single for users to select.

Further, the locking piece is V type marble knot, and the bracing piece is placed in to V type marble knot, and V type marble knot is including the spacing end of interlude in first locking hole.

Further, fixed connection spare is the first connecting piece of M type and the fixed second connecting piece that is the M type at swing joint spare that sets up including fixed setting at the support frame, and the connecting piece is equipped with the hinge hole with swing joint spare matched with, and hinge hole vertical alignment is gone up to first connecting piece hinge hole and second connecting piece equidirectional.

Further, movable connection subassembly include movable connecting piece and with the casting die, movable connecting piece still includes second locking hole, and the casting die still includes locking piece matched with arch, and movable connecting piece is equipped with the sliding part that contracts the locking piece and block into second locking hole by the convex state.

In the above scheme, the pressing piece is inserted in the movable connecting piece, so that friction between the movable connecting piece and the supporting rod is reduced, the movable connecting component can flexibly move along the length direction of the supporting rod, and meanwhile, because the protrusions belong to small parts, the protrusions are easily abraded and damaged, the design of the independent pressing piece is more convenient to replace, and the integral replacement is not needed.

Furthermore, the non-slip mat is equipped with at bracing piece both ends, and the non-slip mat includes anti-skidding end and a plurality of and bracing piece inner wall interference fit's anti-skidding portion and skeleton, and anti-skidding portion is close to the skeleton bottom and is equipped with the fillet that makes things convenient for the holding to advance the support frame inner chamber and make it be difficult for droing, and the skeleton lower extreme of non-slip mat is equipped with the Jiong style of calligraphy pressure relief vent of avoiding producing air pressure during the installation.

In the scheme, the frame is buffered with cover cloth and ground respectively due to the design of the anti-slip mat, the cover cloth is protected from being damaged easily, and potential safety hazards are reduced.

The invention has the following beneficial effects: the novel folding frame is convenient to use, can be connected with cover cloth into a whole through the connection of the frame and the cover cloth, can be unfolded or folded through the relative movement of the rods, is convenient to carry, transport and store, is reasonable in frame layout, can be produced according to the requirements of consumers, can enable the folding frame to have different integral length-width ratios according to different positions of hinged positions, and is simple in structure, simple and convenient to operate and very convenient to provide various specifications for users to select.
