Abstract

The utility model relates to a foldable bounding table with a foldable buffering structure, comprising a bounding table frame and a bounding cloth which is arranged in the bounding table frame by an elastic element; the bounding table frame is formed by two sections of branch pipes which are connected by a foldable piece, the foldable piece comprises a U-shaped sleeve which is used for wrapping the end part of one section of the branch pipe and a lug which is arranged at the lower end surface of the adjacent branch pipe and is protruded out of the U-shaped sleeve, the lug is articulated with the two end arms of the U-shaped sleeve by a pin shaft, and a buffering spring is arranged between the inner end arm of the U-shaped sleeve and the end part of one section of the adjacent branch pipe. The foldable bounding table with the foldable buffering structure not only has safe usage, but also is folded conveniently.

Description

A kind of folding trampoline with folding buffer structure

Technical field:

The utility model relates to a kind of trampoline, especially a kind of folding trampoline with folding buffer structure.

Background technology:

Folding trampoline trampoline of the prior art includes the trampoline frame, by the supporting component that flexible member is installed in the bullet cloth in this trampoline frame and supports the trampoline frame, and the trampoline frame is formed by connecting by a pair of folded piece by two sections arms.Trampoline is when user mode, and flexible member stretches to jump and tightly plays cloth and accumulation of energy, and the user can jump on bullet cloth; Because flexible member accumulation of energy, trampoline are in folding process, this energy discharges rapidly and forces trampoline folding rapidly, because folding rate is too fast and uncontrollable, the operator is easy to be crushed under the untimely situation of dodging, and uses dangerous.

The utility model content:

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of folding trampoline with folding buffer structure of safe in utilization, folding convenient is provided.

A kind of folding trampoline that provides according to the utility model with folding buffer structure, comprise the trampoline frame, be installed in bullet cloth in this trampoline frame by flexible member, described trampoline frame is formed by connecting by a pair of folded piece by two sections arms, described folded piece comprise from top to bottom the U-shaped cover of one section tube end parcel wherein and be arranged on adjacent one section arm lower surface and in stretch in the lug of U-shaped cover, lug is hinged by the two ends arm of bearing pin and U-shaped cover, and described U-shaped overlaps between inner arm and adjacent one section the tube end and by bolt one buffer spring is installed.

The utility model also has following attached technical characterictic:

The mid portion of described two sections arms all is equipped with a folding assisted drag-line.

The packing box of a kind of folding trampoline that provides according to the utility model has following advantage with respect to prior art:

First, in this structure, a buffer spring has been installed in bending place when trampoline is folding, when folding, the pulling force that this buffer spring is stretched and generation is opposite with the trampoline folding direction, effectively slowed down the folding rate of trampoline, guaranteed that the operator is not crushed in the folding process, used as safe as a house;

The second, in this structure, the mid portion of two sections arms all is equipped with a folding assisted drag-line, when trampoline folded, the operator only need push down a wherein arm, firmly spurred the drag-line on another arm then, can fold up two sections arms very easily, folding very convenient.

Description of drawings:

Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structure for amplifying schematic diagram of I among Fig. 1;

Fig. 3 is the structural representation of folded piece in the utility model.

The specific embodiment:

With reference to Fig. 1, Fig. 2, Fig. 3, according to a kind of folding trampoline described in the utility model with folding buffer structure, comprise trampoline frame 1, be installed in bullet cloth 3 in this trampoline frame 1 by flexible member 2, trampoline frame 1 is by two

sections arms

11,12 are formed by connecting by a pair of folded piece 4, wherein,

arm

11,12 can be respectively by two sections hinged forming of steel pipe, folded piece 4 comprise from top to bottom the U-shaped cover 41 of one section arm 11 ends parcel wherein and be arranged on adjacent one section arm 12 lower surface and in stretch in the lug 42 of U-shaped cover 41, lug 42 is hinged with the two ends arm of U-shaped cover 41 by bearing pin 5, U-shaped overlaps between 41 inner arms and adjacent one section arm 12 end and by bolt 6 buffer spring 7 is installed, trampoline is when folding, the pulling force that this buffer spring 7 is stretched and generation is opposite with the trampoline folding direction, effectively slowed down the folding rate of trampoline, guaranteed that the operator is not crushed in the folding process, used as safe as a house.

The mid portion of two

sections arms

11,12 all is equipped with a folding assisted drag-line 8, when trampoline folds, the operator only need push down arm 11, firmly spur the drag-line 8 on the arm 12 then, or push down arm 12, firmly spur the drag-line 8 on the arm 11 then, can fold up two

sections arms

11,12 very easily.

The foregoing description is only for the usefulness that the utility model is described; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
