Description

A kind of rotating device for trampoline support

Technical field

It the utility model is related to spring trampoline, specifically a kind of rotating device for trampoline support.

Background technology

Increasingly burning hot with the market of spring trampoline, diversified spring trampoline emerges in an endless stream, and volume also the more is done the more big, The problem of transport of trampoline and in-site installation, also just increasingly highlights, and substantial amounts of space is taken in transportation, at the scene Wasted time and energy in installation, greatly reduce operating efficiency, increase cost.

Utility model content

Technical problem to be solved in the utility model is, the shortcomings that for above prior art, proposes a kind of to be used to jump The rotating device of bedrest, is not only simple in structure, easy to operate, improves operating efficiency, and saves space, and cost is low, safety Reliably, service life is grown.

In order to solve the above-mentioned technical problem, the technical solution of the utility model is achieved in the following ways：One kind is used In the rotating device of trampoline support, including the spring bed frame of regular polygon is shaped as, justified in spring bed frame lower surface along it Circumferential direction is uniformly provided with support rotating device, and support rotating device includes bearing, and bearing is into cylindrical type, in bearing lower surface along bullet The parallel direction in spring bed frame one side offers U-shaped hole, and cross recess, section of the bearing along U-shaped hole are offered in the bottom of U-shaped hole Direction offers elongated hole, is provided with support in U-shaped hole, sequentially passes through elongated hole, support by bearing pin, support is fixed with bearing, and Support is provided with the cross boss to match with cross recess close to the top of bearing, and bearing pin can be moved up and down freely in elongated hole, when Bearing pin is moved to elongated hole lower end, then support can be rotated freely, and when bearing pin is moved to elongated hole upper end, then cross boss is embedded in cross In groove, support can not be rotated freely.

So, by the technical solution of the utility model, design a bearing, set on bearing U-shaped hole, cross recess, The structures such as elongated hole, when in use, bearing pin are moved to elongated hole upper end, then in cross boss insertion cross recess, support can not be certainly By rotating, when needing to transport and dismantling, bearing pin only need to be moved to elongated hole lower end, you can swinging mounting, realize and fold Function, this is simple in construction, easy to operate, and cost is low, improves operating efficiency, substantially reduces the volume of trampoline.

The technical scheme that the utility model further limits is：

The rotating device of trampoline support is previously described for, spring mattress bed frame perimeter is provided with counter balance pocket, increased by counter balance pocket Weight, trampoline disengaging ground in use is avoided, causes safety problem.

The beneficial effects of the utility model are：A bearing is designed, the knot such as U-shaped hole, cross recess, elongated hole is set on bearing Structure, when in use, bearing pin are moved to elongated hole upper end, then in cross boss insertion cross recess, support can not be rotated freely, when When needing to transport and dismantle, bearing pin only need to be moved to elongated hole lower end, you can swinging mounting, the function of folding is realized, should Simple in construction, easy to operate, cost is low, improves operating efficiency, substantially reduces the volume of trampoline.

Embodiment

The utility model is described in further detail below：

Embodiment 1

A kind of rotating device for trampoline support that the present embodiment provides, including it is shaped as the spring mattress bed frame of regular polygon Frame 1,6 support rotating devices are uniformly provided with along its circumferencial direction in the lower surface of spring bed frame 1, support rotating device includes branch Seat 2, bearing 2 offer U-shaped hole 3, in U-shaped in the lower surface of bearing 2 into cylindrical type along the parallel direction in the one side of spring bed frame 1 The bottom in hole 3 offers cross recess 4, and cross-wise direction of the bearing 2 along U-shaped hole 3 offers elongated hole 5, support 6 is provided with U-shaped hole 3, Elongated hole 5, support 6 are sequentially passed through by bearing pin 7, support 6 is fixed with bearing 2, and support 6 close to the top of bearing 2 be provided with The cross boss 8 that cross recess 4 matches, bearing pin 7 can be moved up and down freely in elongated hole 5, when bearing pin 7 is moved to the lower end of elongated hole 5, Then support 6 can be rotated freely, and when bearing pin 7 is moved to the upper end of elongated hole 5, then cross boss 8 is embedded in cross recess 4, and support 6 can not Freely rotate；The periphery of spring bed frame 1 is provided with counter balance pocket 9, by counter balance pocket increase weight, avoid in use trampoline take off From the ground, safety problem is caused.

So by the technical scheme of the present embodiment, a bearing is designed, U-shaped hole, cross recess, elongated hole are set on bearing Etc. structure, when in use, bearing pin is moved to elongated hole upper end, then in cross boss insertion cross recess, support can not freely turn It is dynamic, when needing to transport and dismantling, bearing pin only need to be moved to elongated hole lower end, you can swinging mounting, realize the work(of folding Can, this is simple in construction, easy to operate, and cost is low, improves operating efficiency, substantially reduces the volume of trampoline.

Above example is only to illustrate technological thought of the present utility model, it is impossible to limits protection model of the present utility model with this Enclose, it is every according to the utility model proposes technological thought, any change done on the basis of technical scheme, each fall within this reality Within the scope of novel protected.
