Description

Trampoline outer shroud bridge joint pipe connected structure

Technical field

The utility model relates to the connected structure that trampoline is taken over, and refers to a kind of more strong and reliable trampoline outer shroud of package assembly bridge joint pipe connected structure that makes this type of adapter especially.

Background technology

With trampoline and so on sports equipment is example; basically be the elasticity tension face that is provided with a tensioned state outside between the ring stand; the user can carry out various jumping on this elasticity tension face; for making whole elasticity tension mask that required flexible tension force nargin be arranged, this elasticity tension face can be set at the desired height place by foot rest usually.

And the elasticity tension face that this type of trampoline ammunition feed is jumped is typically provided with sizable area, so its outer ring stand also must be provided with bigger diameter, so can't make with single tubing, must form to take over to engage piecemeal.

Referring to Fig. 1-3, with two adapters 10,20 that are connected each other is example, wherein one take over 10 and be provided with the minor diameter part 11 that contracts in cohesive end, this minor diameter part 11 punching press in advance fluted 13 of contracting, another relative with it taken over 20 then pre-subpunches and is provided with and groove 13 corresponding indent rail bars 22, two take over 10,20 sockets mutually, and make indent rail bar 22 be embedded in joint location in the groove 13.

But this kind commonly used in the connected structure that the trampoline ring stand takes over, and two take over 10,20 junction only relies on engaging of indent rail bar 22 and groove 13.Owing to be subjected to taking over the restriction of 10,20 pipe thicknesses, no matter groove 13 or indent rail bar 22 are all can't punching press dark excessively, that is the radial depth that both combine is limited, this point causes the instability of its bond strength, simultaneously, use contains on the trampoline of non-directional twisting force at this type of, and its circumferential twisting resistance effect is obviously not enough.

Summary of the invention

The purpose of this utility model, be to provide a kind of trampoline outer shroud bridge joint pipe connected structure, it one is taken over and is connected pad and clip slot in the end pre-aligned in two be connected to take over, one radially another adapter of pin be inserted in this clip slot, make two take over firm reliably.

For reaching above-mentioned purpose, a kind of trampoline outer shroud bridge joint pipe connected structure of the present utility model, wherein taking over cohesive end and be preset with the minor diameter part that contracts of the two-phase butt tube that is connected piecemeal as the outer ring stand of trampoline is characterized in that; This minor diameter part that contracts is provided with relative clip slot in advance, and an interior pad is fixedly arranged on the inner tube of this adapter, and is provided with and the corresponding opening clip slot of above-mentioned relative clip slot; And another is taken over and to be equipped with a pin radially with one section setpoint distance place of its end part interval, this radially pin can deeply be incorporated in the above-mentioned clip slot.Wherein,

Pad is preset with a recessed neck in location that contains endoporus in described, and a pin member is taken over outer the insertion by this and engaged the location in this endoporus.

The radially pin of described another adapter forms radially to insert the location by pipe is outer with a pivot pin.

The utility model since one take over cohesive end with pin radially deeply in conjunction with and insert in wherein another adapter and each clip slot of neck bush thereof, and make both more reliable and stable in conjunction with getting, has circumferential positioning action because of it again, also can prevent the situation generation of rocking or make structural damage that non-directional torsion is caused, the service life that for this reason can improve trampoline.

The specific embodiment

For to the purpose of this utility model, technical characterictic and effect thereof, can have and further be familiar with and understand, lift a preferred embodiment now, and conjunction with figs. is described in detail as follows:

Referring to Fig. 4,5, in the two- phase butt tube 30,40, wherein one to take over 30 and be provided with the minor diameter part 31 that contracts at cohesive end, this minor diameter part 31 that contracts dashes establishes two relative clip slots 33.And pad 50 presses solidly in the inner tube of this adapter 30 in one, and combines location with interior pad 50 by pipe is outer with a pin member 51 after taking over wall.Pad 50 also is provided with and clip slot 33 corresponding opening clip slots 53 in this.

In the present embodiment, should be preset with the recessed neck 55 that contains endoporus by interior pad 50, so that pin member 51 can be according to accurate direction by the outer combination of pegging graft of pipe, another relatively take over 40 then energy leave one section suitable distance with its end 42 and be preset with perforate 44, one pin 46 is engaged, whole pin 46 thereby can take over formation one radial location pivot pin in 40 by outer insertion of pipe.

Referring to Fig. 6-8, take over 30,40 when preparing to engage when above-mentioned two, make and take over 40 inside pin 46 and aim at another and take over 30 and interior pad 50 formed clip slots 33,53, both can be abutted against mutually and form engagement state (shown in Fig. 4,8).At this moment, taking over 40 pre-aligned pins 46 is inserted in each clip slot 33,53 fully with landscape mode.

Referring to Fig. 9, when the utility model is installed to 90 somes of ring stand outside the trampoline piecemeal, all take over 30,40 inside can be by the adapter brace 91 location inner elastomeric tension force faces 92 of screening, as outside in the adapter piecemeal of ring stand 90, each adapter 30,40 all can be provided with the little radian shape of all shapes of common formation outer shroud.

It below only is the utility model one preferred embodiment; be not to limit practical range of the present utility model with this; know and know this skill personage; all disengaging under the utility model spirit and the principle; various distortion and the modification done all should be covered by within the patent protection category that the utility model claims are defined.
