Abstract

The utility model relates to a novel trampoline, which belongs to the field of trampoline manufacturing technology of running apparatus. The utility model mainly comprises a periphery frame, the lower part of which is provided with a short branch pipe (3), an elastic element (8) which is arranged in the periphery frame and provided with a bouncing surface (9), a connecting pipe (4) and a foot bracket (5) which are arranged on the lower part of the short branch pipe (3), and guard bars (7) which are respectively fixed on the short branch pipe (3) and the foot bracket (5), wherein the periphery frame is formed by that three to eight long outer frames (1) and short outer frames (2) are alternately sheathed, the short branch pipe (3) is fixedly connected to the position near both ends of the long outer frames (1), the length ratio of the long outer frames (1) and the short outer frames (2) is from 1: 1 to 2: 1, and the distance of the fixed connection point H of the short branch pipe (3) on the long outer frames (1) and the connection position A of both ends of the long outer frames (1) is from 5 centimeters to 30 centimeters. The utility model has the advantage of reasonable design, the impact strength, uniform distribution of safe surrounding net and the producing efficiency can be increased effectively after the periphery frame and the whole frame are combined, the degree of beautiful appearance is increased and the utility model is convenient for quick arrangement and production.

Description

A kind of novel jumping bed

Technical field

The utility model relates to a kind of novel jumping bed, belongs to the manufacturing technology field of trampoline.

Background technology

Trampoline mainly is provided with the spring face that a plurality of flexible members are formed in circular frame inside, the periphery is provided with the safe fences that is higher than trampoline spring face, and its frame structure is formed by combining by peripheral frame, short arm, junction pipe, foot support and fences guard bar usually.Make for convenience and transportation, usually the circular circumference framework is divided into multistage, carry out composite joint by the method for an end necking down.

Referring to accompanying drawing 1,2, the circular circumference framework that the frame structure of existing trampoline mainly is made up of branch pipe fittings 10 such as multistages, and affixed one short arm 3 connects their frames by junction pipe 4 usefulness foot supports 5 again at the middle part of branch pipe fitting 10 such as every section, and 7 of guard bars are fastened on the junction pipe 4.The junction A of the stressed weakness of such its maximum of frame structure between two five equilibrium pipe fittings 10, when this point was subjected to certain external force, whole circular circumference framework formed the doubling shape easily, has a strong impact on its security.Have in order to increase the intensity of circular circumference framework, the junction A of two five equilibrium pipe fittings 10 in addition screw fix, production difficulty and manufacturing cost also increase simultaneously when intensity increases like this.

Summary of the invention

The purpose of this utility model provides a kind of reasonable in design, can effectively improve the even distribution of the impact strength after peripheral frame and general frame make up, safe purse seine and produce effectiveness, increases the good looking appearance degree, is convenient to the novel jumping bed of Fast Installation and making.

The utility model is a kind of novel jumping bed, the peripheral frame that comprises the short arm of bottom band, place the flexible member of band spring face in the peripheral frame, place the foot support of short arm bottom, be fixed in the guard bar on short arm and the foot support, it is characterized in that peripheral frame replaces socket by 3-8 segment length's housing and short housing and constitutes, described short arm is fixed in the position near long housing two ends.

The length ratio of described long housing and short housing can be 1.1-2: 1.

The affixed some H of described short arm on long housing can be 5-30 centimetre with the distance L at long housing both ends.

Described short arm and foot support and guard bar can be embraced folder by hinge type and connect fixing.

Also can be provided with junction pipe between described short arm and the foot support.

Described long housing, short housing, short arm, junction pipe, foot support, guard bar can be the hollow circular tube of deciding diameter.

Described foot support can be U-shaped, W shape or V-arrangement pipe.

The utility model employing replaces socket by 3-6 segment length's housing and short housing and constitutes peripheral frame, and will lack the position that arm places close long housing two ends, make the design of trampoline peripheral frame more become reasonable, both reached and made the equilateral purpose of foot support, strengthened the structural strength of peripheral frame again, can prevent effectively that peripheral frame from falling apart and outside junction is born the load intensity defect of insufficient, in also having avoided producing with complicated technologies such as screws.Simultaneously safe fences guard bar is fastened on short arm and the foot support, can effectively prevents falling apart between short arm, junction pipe, the foot support, make trampoline general frame structure be coupled to one effectively.

Description of drawings

Fig. 1 is the overall structure vertical view of existing trampoline;

Fig. 2 is the partial structurtes schematic diagram of existing trampoline;

Fig. 3 is an overall structure vertical view of the present utility model;

Fig. 4 is a partial structurtes schematic diagram of the present utility model.

Among the figure, 1 for long housing, and 2 are short housing, and 3 are short arm, and 4 be junction pipe, and 5 be foot support, and 6 embrace folder for hinge type, and 7 is guard bar, and 8 is flexible member, and 9 is spring face, and 10 is the five equilibrium pipe fitting that has now on the trampoline peripheral frame.

The specific embodiment

The utility model mainly comprises the peripheral frame of the short arm 3 of bottom band, places the flexible member 8 of band spring face 9 in the peripheral frame, places the junction pipe 4 and the foot support 5 of short arm 3 bottoms, is individually fixed in the guard bar 7 on short arm 3 and the foot support 5.Peripheral frame replaces socket by 3-8 segment length's housing 1 and short housing 2 and constitutes, and short arm 3 is fixed in the position near long housing 1 two ends.The length of long housing 1 and short housing 2 is than being 1.1-2: 1, and the affixed some H of short arm 3 on long housing 1 is 5-30 centimetre with the distance L of long housing 1 both ends junction A, short arm 3 and foot support 5 are embraced folder 6 connections with guard bar 7 by hinge type and are fixed.

Accompanying drawing 3,4 is the utility model one preferred embodiment, the short housing 2 of the long housing 1 of multistage and multistage makes it be socketed in an end of another not reducing by an end reducing wherein, form a circular circumference framework, respectively weld a short arm 3 in position near long housing 1 two ends junction A, foot support 5 is embedded in short arm 3 bottoms by junction pipe 4, embrace folder 6 with hinge type safer fences guard bar 7 is fastened on short arm 3 and the foot support 5, thereby be combined into whole trampoline frame structure.Spread spring face 9 then out, be fixed on the peripheral frame with flexible member 8, lay protection pad on flexible member 8, promptly constitute the trampoline with location height spring face 9, the required safe fences of height winding according to guard bar 1 can use.
