Abstract
The invention discloses a folding trampoline connecting piece, belonging to the trampoline technical field, which includes two articulated connecting pieces I, II, wherein the working face of the connecting pieces I, II, has an inclined plane with a complementary angle. A through hole is arranged on the connecting pieces I, II, perpendicular to the working face and on the same axial. The two through holes pass through the binding bolt and in the pivot joint. The folding trampoline connecting piece of the invention not only solves the problem, when the round trampoline uses the folding path of non-onehalf of the circle for folding, the transmission shaft of the two connecting pieces on the two ends of the folding path and the transmission shaft of the movable tube are not on the same line, so an abdication angle for clashing are provided, making the round trampoline can be freely folded, and having simple structure, convenient mounting, and low cost.
Description
Technical field
The invention discloses a kind of connection elements of folding recreation bouncer, belong to trampoline technical field.
Background technology
Trampoline is as a kind of athletic sports appliance of leisure, and is very popular, but when not using, can occupy certain space.Therefore, the collapsible trampoline that has also progressively occurred multiple pattern on the market.Most in the market trampoline is circular, and the folding of it is to realize by one group of broken line of 1/2nd circles, but this is not suitable for than relatively large circular trampoline.Because large-scale circular trampoline not only takes manpower if come to fold in this way very much, and carry, deposit inconvenience.Therefore, we have expected solving this problem by the many groups fold line less than 1/2nd circles.But originally used on the connector (its working face is vertical plane) on 1/2nd broken lines of justifying is not suitable for less than 1/2nd fold lines of justifying, because its folding angle problem of stepping down that has the two connector folding points head-on collision at fold line two ends all the time, promptly the turning cylinder of the turning cylinder of two connectors and active ring pipe is not on same straight line, thereby the folding of circular trampoline hindered, do not reach expected effect.If do not select to fold, but the dismounting storage faces again and uses preceding loaded down with trivial details assembling next time.
Summary of the invention
In order to address the above problem, the invention provides a kind of connection elements of folding recreation bouncer that is applicable to that non-1/2nd round fold lines fold.
To achieve these goals, the technical solution adopted in the present invention is: a kind of connection elements of folding recreation bouncer, comprise two the connector I that are hinged, connector II, the working face of described connector I, connector II is the inclined plane of the complementary angle of tool, be respectively equipped with perpendicular to working face and the through hole on same axis on connector I, the connector II, wear fastening bolt between this two through hole and articulate with it.The turning cylinder (fastening bolt) that two connectors making the fold line two ends more than are set and the turning cylinder of active ring pipe are on same straight line, thereby solved the angle problem of stepping down of head-on collision, made circular trampoline folding freely (active ring pipe can the fastening bolt on connector rotate freely).
As the further setting of such scheme, leave rotation between the working face front end of described connector I and the working face bottom and allow bit space; Leave rotation between the working face bottom of described connector II and the working face front end and allow bit space.Rotation allows the setting of bit space, has further guaranteed the folding free degree of circular trampoline.
Described connector I is provided with through hole; Described connector II is provided with two counterbores; Positioning mounting passes through hole, and it draws the pin head can embed in any counterbore.Being provided with of positioning mounting helps connector maintenance stable status, guaranteed the safe handling of connector on trampoline.
Be provided with connecting pin between the through hole on described connector I, the connector II, connecting pin is embedded in the counterbore of the counterbore of connector I through hole and connector II through hole.Being provided with of connecting pin can have been kept out bigger shearing force, improved the bonding strength between connector I and the connector II.
The bottom of described two working faces all offers the chamfering of stepping down.
The through hole of described connector II has internal thread.
The described through hole that is installed with positioning mounting has internal thread.
Connection elements of folding recreation bouncer of the present invention not only can solve circular trampoline with the fold lines of non-1/2nd circles when folding, the angle problem of stepping down that on same straight line, does not have head-on collision because of the turning cylinder of the turning cylinder of two connectors at fold line two ends and active ring pipe, make circular trampoline folding freely, and simple in structure, easy for installation, cost is low.

The specific embodiment
As shown in Figure 1, 2, connection elements of folding recreation bouncer of the present invention connects to form four sections loop pipes the circular bedstead of trampoline.Shown in Fig. 3,4,5,6,7,8,9, connection elements of folding recreation bouncer of the present invention comprises two the connector I1 that are hinged, connector II2, and the working face 3,4 of connector I1, connector II2 is the inclined plane of the complementary angle of tool.Connector I1 is connected on the retainer plate pipe, and connector II2 is connected on the active ring pipe.Connector I1, connector II2 are provided with perpendicular to working face 3,4 and the through hole on same axis 7,8, and 7,8 of this through holes wear fastening bolt 6 and articulate with it.Through hole 8 has internal thread.Also be provided with through hole 5 on the connector I1 with internal thread; Connector II2 is provided with counterbore 10,11; Positioning mounting 9 passes through hole 5, and it draws pin head 17 to embed in the counterbore 10 or 11.Be provided with connecting pin 12 between through hole 7 and the through hole 8, in the counterbore 13 that connecting pin 12 is embedded in through hole 7 and the counterbore 14 of through hole 8.The bottom 15,16 of working face 3,4 all offers the chamfering 20,21 of stepping down.Certainly, the front end 18,19 that also can be chosen in working face 3,4 is all offered the circular arc of stepping down.
Operation principle of the present invention is: when sheet launches, connector is straight as Fig. 8, starts the positioning function of positioning mounting 9, and the pin head 17 that draws on the positioning mounting 9 is embedded in the counterbore 11, make connector keep the horizontal stable state, prevent that sheet is because of the spring tension auto-folder.
In the time will folding trampoline, remove the positioning function of positioning mounting 9 earlier, be about to draw pin head 17 to be pulled away from counterbore 11, the active ring pipe is folded to plumbness such as Fig. 9, then start positioning function once more, the pin head 17 that draws on the positioning mounting 9 is embedded in the counterbore 10, fold plane is maintained, hurt sb.'s feelings to prevent that fold plane is turned down in moving process.
