Description
Technical field
It the utility model is related to trampoline technical field, more particularly to a kind of trampoline attachment means of double insurance.
Background technology
Trampoline is mainly used in physical culture, body-building and amusement etc., is mainly made up of framework and support foot rest, and support foot rest is used
In support frame, a spring face tightened is set between framework, while support frame and spring face are connected using flexible member,
User can carry out various jump actions on spring face, and the trampoline species of in the market is a lot, have detachable, fixed
And adjustable height formula, configurations, function various kinds.
Most of trampolines are all fixed that is, support frame and framework are an entirety, and volume is larger, nothing in the market
Method is split, and space-consuming is big, is unfavorable for transporting and is deposited, also, when support frame breaks down, due to trampoline support frame and
Framework is integral, it is impossible to is replaced, so whole trampoline cannot also use.In order to solve this problem, by the branch of trampoline
It is arranged to detachable between support and framework, becomes detachable trampoline, but such trampoline is in the company of support frame and framework
Socket part position needs exactissima diligentia.Many trampolines are made inadequate in this respect now, and after long-time use, connecting portion easily comes loose
Or deform, it is prone to accidents.
Utility model content
For the presence of existing phenomenon, the purpose of this utility model is to provide a kind of simple, rational double insurance
Trampoline, the problem of specifically for trampoline, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of trampoline attachment means of double insurance, it is characterised in that：Including framework and support frame, the bottom of the framework
Provided with some connecting portions, the connecting portion uniform circular is distributed in the bottom of framework, and the connecting portion is arranged to cylindrical shape, described
The outer surface of connecting portion is provided with screw thread one, and the connecting portion is provided centrally with endoporus, and the inner surface setting of the endoporus has
The screw thread two oppositely oriented with screw thread one, support frame as described above include sleeve and pole, and outside and the pole of the sleeve are welded, institute
Stating sleeve includes upper cartridge, in the middle part of lower cartridge and sleeve, and the upper cartridge is provided centrally with through hole one, described logical
The aperture of Kong Yiyu connecting portions is identical, and the centrally disposed through hole two in the middle part of the sleeve, the lower cartridge is provided centrally with
Through hole three, the aperture of the through hole two is consistent with the aperture of endoporus, and its size is the 1/3 of the aperture of through hole one, the through hole
Two inner surface setting has screw thread three, and the screw thread three is identical with the thread rotary orientation of screw thread two, and the inner surface of the through hole one is set
It is equipped with the screw thread four oppositely oriented with screw thread one.
By using above-mentioned technical proposal, sleeve and connecting portion are coordinated, through hole one is connected with connecting portion outer ring by screw thread
Connect, then connected through hole two with endoporus from through hole three with bolt, realize it is dual be fixedly connected, and two kinds connection modes
The rotation direction of screw thread is inconsistent, no matter which side support frame rotate toward, all the more can revolve the more tight, until revolving motionless.
As preferred：The upper end of the pole is bent outwardly, and its lower end is perpendicular to ground.
As preferred：The through hole three is internally provided with leather sheath.
By using above-mentioned technical proposal, pole upper end is bent outwardly, and lower end is vertical, makes the overall floor space of pole big
In the framework of trampoline, trampoline can be made more stable when placing, be not susceptible to turn on one's side；Leather sheath is provided with through hole three, works as bolt
After through hole two is connected with endoporus, leather sheath is enclosed in through hole three, can effectively prevent bolt from losing and getting rusty.
The utility model has the advantage of：1. structure design advantages of simple, and convenient disassembly, suitable for most trampolines；
2. connecting portion is arranged into dual fixation, trampoline is set to be connected with support frame even closer；3. pole entirety floor space is set
More than the framework of trampoline, trampoline can be made more stable when placing, be not susceptible to turn on one's side.
Brief description of the drawings
Fig. 1 is a kind of trampoline attachment means structural representation of double insurance of the utility model.
