Abstract
The utility model relates to a body-building and amusement facility, in particular to a leg folding mechanism of a rectangle trampoline, which mainly resolves the technical problems that the connection structure of the current trampolines is complex, the leg is only straight and the trampoline is unstable to use in the prior art. The utility model comprises a rectangle framework (1), wherein the long sides of the framework (1) are hinged with two U-shaped legs (2), the transverse lever (3) of each leg is hinged with a lower connecting rod (4), and each of the short sides of the framework is hinged with an upper connecting rod (5) at the position corresponding to the lower connection rod, and each the upper connecting rod and each the lower connecting rod can be movably connected via the end portions.
Description
Technical field
The utility model relates to a kind of body-building, recreational facilities, especially relates to a kind of to the isostructural improvement of rectangle trampoline leg fold mechanism.
Background technology
Trampoline generally can be used for physical culture, amusement aspect, its by bed frame, the cloth that bounces, be connected in bed frame and spring between the cloth flexible member such as several feets of spring or elastic woven tape and supporting bed framework form, the bed frame of its early production can not folding, cause collection inconvenience, also increased the packing of product and cost of transportation simultaneously.Chinese patent discloses a kind of folding trampoline, and (Granted publication number: CN2673443Y), framework that it is combined by a multisection type framework and the spring face of being located in the framework are formed; Be provided with most elastic parts between this framework and the spring face, each elastic parts one end buckles in framework, and the other end then buckles in the outer bead of spring face, forms the required elastic force of jumping to tighten spring face; In the multisection type framework in twos each junction of framework be provided with most legs, have at least a pair of leg to be provided with second joint mechanism in this leg, this articulation mechanism is respectively equipped with a chuck in two adjacent framework ends, each chuck rear end is individually fixed in adjacent two framework ends, and each chuck front end is then articulated by the bearing pin between mutually folded auricle that extends the jag sheet and respective leg.But the trampoline syndeton of this structure is comparatively complicated, and leg is straight rod type, and trampoline is unstable in use.
Summary of the invention
The purpose of this utility model provides a kind of square-folded trampoline, and it mainly is that to solve existing in prior technology trampoline syndeton comparatively complicated, and leg is straight rod type, and trampoline is in use than the technical problem of instability etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Rectangle trampoline leg fold mechanism of the present utility model, comprise a rectangular frame, the long limit that it is characterized in that described framework is hinged with two " ∏ " shape legs, be hinged with lower connecting rod on the cross bar of leg, the minor face of framework and lower connecting rod are hinged with upper connecting rod on the corresponding position, and two connecting rods are in the movable connection in its end.Two connecting rods can be fixed together into straight rod type, also can rotate around its pin joint in its end dismounting.When connecting rod was affixed, itself and leg were not parallel, guaranteed that like this a foot lever can support on the ground, and be comparatively stable.
As preferably, the upper connecting rod on lower connecting rod on the described cross bar and the framework minor face all is two, and two paired connecting rods all flexibly connect in its end.Following connector position on the framework minor face on hinged two upper connector positions and the cross bar adapts.
As preferably, all be connected with " U " type connector on described framework, the cross bar, leg, connecting rod are hinged by connector and framework, cross bar respectively.The welding of " U " type connector end and framework, cross bar, leg, connecting rod be by the inside of bolted splice at two lateral plates of " U " connector, is convenient to leg like this or connecting rod rotates around pin joint.
As preferably, the upper connecting rod on lower connecting rod on the described cross bar and the framework minor face is in the mutual socket in its end, and has installing hole on the shaft of connecting rod end.In the paired upper and lower connecting rod, the diameter of a connecting rod end is less than another root connecting rod diameter, and like this, the connecting rod that diameter is little can insert in another root connecting rod, by insert alignment pin in locating hole, reaches affixed purpose then.
Therefore, the utlity model has between the leg of trampoline has cross bar, is provided with easy-to-dismount connecting rod between cross bar and the trampoline framework, makes trampoline comparatively stable in use, characteristics such as simple again, reasonable during dismounting.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is right TV structure schematic diagrames of Fig. 1;
Accompanying drawing 3 is the structural representations of looking up of Fig. 1;
Accompanying drawing 4 is polycrystalline substance schematic diagrames of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the rectangle trampoline leg fold mechanism that this is routine as Fig. 1, Fig. 2, Fig. 3, is connected with jumping cloth 7 by spring in the rectangular frame 1 that is formed from steel, framework.The bottom on framework 1 long limit is welded with two " U " type connectors 6, and the leg 2 of " ∏ " shape is hinged in the connector 6.Be hinged with two lower connecting rods 4 on the cross bar 3 of leg, being hinged with 5, two connecting rod ends of two upper connecting rods on the corresponding position of the minor face of framework 1 and lower connecting rod can be docking together.Lower connecting rod 4 end diameter are less than upper connecting rod 5 end diameter, and the connecting rod end has the installing hole 5-1 that adapts.When two connecting rods docked mutually, itself and leg 2 were not parallel.
During use, leg 2 pulled down prop up ground, lower connecting rod 4 ends are inserted in upper connecting rod 5 ends, insert in installing hole 5-1 that alignment pin is fixing to get final product, be i.e. the right positions of Fig. 3, Fig. 4.During dismounting, turn on alignment pin, with two connecting rods of butt joint separately, then respectively to invagination, again with leg 2 to the inside turnover, get final product up to the leftward position of Fig. 3, Fig. 4.
