Abstract
Description
Technical Field
[0001] This utility model relates to a folding trampoline. Background Technology
[0002] Chinese invention patent application number 202410938439.2, entitled "Trampoline," includes a bouncy surface and a foldable bed frame. The foldable bed frame includes a polygonal frame surrounded by multiple side rods and a support assembly located below each side rod. A connecting plate is provided between each pair of adjacent side rods, and each side rod includes two sections. The proximal ends of the two sections are pivotally connected to each other, and the distal ends of the two sections are pivotally connected to the corresponding connecting plate. A support base is provided below each connecting plate. Each support assembly includes two X-shaped cross-pivoted support rods. The upper ends of the two support rods are pivotally connected to the corresponding connecting plate, and the lower ends of the two support rods are pivotally connected to the corresponding support base. The bouncy surface is located within the polygonal frame, and the periphery of the bouncy surface, together with the polygonal frame, support assemblies, bouncy surface, connecting rods, and handrails, folds inward through several connectors. Although the trampoline has a folding structure, the lack of a support column between the connecting plate and the support base, with the upper and lower ends of the two-section rod connecting the corresponding connecting plate and support base respectively, not only results in poor stability of the entire trampoline structure, but also leads to a large folded volume that occupies a significant amount of storage space. Utility Model Content
[0003] This utility model provides a folding trampoline, which overcomes the shortcomings of the prior art. The technical solution adopted by this utility model to solve its technical problem is as follows:
[0004] A folding trampoline includes a folding frame and an elastic fabric. The folding frame includes several upper connecting seats, several lower connecting seats, several connecting rods, and several crossbar assemblies, wherein:
[0005] Each link includes a first link, a second link, and a pivot seat. The tail ends of the first link and the second link are pivotally connected to the two sides of the pivot seat, respectively. The head ends of the first link and the head ends of the second link are pivotally connected to two adjacent upper connecting seats, respectively.
[0006] Each crossbar assembly includes a first folding rod, a second folding rod, a movable sleeve, and a support rod. The top end of the support rod is fixedly connected to a pivot seat. The movable sleeve is movably fitted around the outer periphery of the support rod and can move up and down along the length of the support rod. The first folding rod and the second folding rod are hinged together, and their hinge connection point is located on the movable sleeve. The top ends of the first folding rod and the second folding rod are respectively pivotally connected to two adjacent upper connecting seats. The bottom ends of the first folding rod and the second folding rod are respectively pivotally connected to two adjacent lower connecting seats. The elastic fabric edge is connected to each connecting rod.
[0007] When the folding frame is in the open state, the first folding rod and the second folding rod are in a cross-open state, the first connecting rod and the second connecting rod are in a horizontal state and located on the same plane, and several connecting rods form a closed shape, and the elastic fabric is stretched outward; during the folding process, the head ends of the first connecting rod and the head ends of the second connecting rod are both folded upward, and the tail ends of the first connecting rod and the tail ends of the second connecting rod are both folded downward, the first folding rod and the second folding rod are folded together and close together, the movable sleeve moves upward along the support rod, and the hinge connection of the first folding rod and the second folding rod can move upward synchronously with the movable sleeve until the folding frame is generally in a vertical state and moves closer to the center of the trampoline, and the elastic fabric is folded inward.
[0008] In a preferred embodiment: the support rod is provided with a limiting part for limiting the movement of the movable sleeve, and the movement stroke of the movable sleeve is located between the pivot seat and the limiting part.
[0009] In a preferred embodiment: the inner side of the movable sleeve is provided with a riveting hole, and the cross rod group is provided with a hinge shaft, which passes through the first folding rod and the second folding rod and is riveted to the riveting hole.
[0010] In a preferred embodiment, the upper connecting seat and the lower connecting seat are arranged vertically and horizontally in a one-to-one correspondence.
[0011] In a preferred embodiment: the folding frame further includes at least one handrail, the upper connecting seat and the lower connecting seat are respectively provided with an upper through hole and a lower insertion hole, and the bottom end of the handrail passes through the upper through hole and is inserted into the lower insertion hole.
[0012] In a preferred embodiment: the handrail adopts a telescopic rod structure.
[0013] In a preferred embodiment: the handrail is formed by detachable plug-in rods, and the handrail is provided with two plug-in feet, each of which can pass through the upper through hole and then be plugged into the two lower plug-in holes.
[0014] In a preferred embodiment: the folding frame further includes a protective net structure, the protective net structure includes several guard rods and a protective net, the upper connecting seat and the lower connecting seat are respectively provided with an upper through hole and a lower insertion hole, the bottom end of the guard rod passes through the upper through hole and is inserted into the lower insertion hole, and the protective net is hung around the guard rod.
[0015] In a preferred embodiment: when the folding frame is in the open state, a plurality of links form a quadrilateral shape or an even-numbered side shape with four or more sides.
[0016] Compared with the prior art, this technical solution has the following advantages:
[0017] 1. When the folding frame is in the open state, several connecting rods form a closed shape, and the support rods can support the pivot seats, increasing the support force and making the entire folding frame stronger, more stable, and safer during use. During the folding process, the movable sleeve moves upward along the support rods, and the hinge connection between the first and second folding rods moves upward synchronously with the movable sleeves. This ensures that when folded, the first and second connecting rods are roughly vertical and arranged vertically with the support rods, resulting in a smaller overall folded volume and less storage space occupied.
[0018] 2. The setting of the limiting part can limit the movement of the movable sleeve and prevent the movable sleeve from falling off the support rod. Attached Figure Description
