The invention has the benefit that trampoline of the present invention, the bending stiffness of flexible link is 500-1200N/m, is resisted Curved rigidity is moderate, installs laborsaving convenience, and ordinary consumer can be installed voluntarily, reduces the difficulty of trampoline installation, improves installation peace Quan Xing.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of trampoline of the present invention.
Fig. 2 is the structural schematic diagram of the flexible link of buckle structure of the present invention.
Specific embodiment
In order to make goal of the invention of the invention, technical solution and technical effect are more clearly understood, below with reference to specific reality Applying mode, the present invention is described further.It should be understood that specific embodiment described herein, for explaining only the invention, It is not intended to limit the present invention.
Referring to Figures 1 and 2, instantly popular trampoline generally includes cushion 10 and support base 20, and mostly with flexible link 30, The bottom end 32 and top 31 of the flexible link 30 are separately mounted to 10 periphery of the support base 20 and the cushion, thus will be described Cushion 10 is supported on 30 top of support base.User can bounce on cushion 10, play and perform.
In order to support cushion and user, the flexible link 30 usually requires have certain bend resistance power.It is especially described When flexible link 30 is installed, usually 30 bottom of flexible link is first fixed on the support base 20, then by the flexible link 30 Top deflects about 300~450mm from natural placement status to 10 center position of cushion.The bending stiffness and material of flexible link Expect that property, geometry are related.In the case where material determines, each section of the bending stiffness of cylindrical flexible link 30 in bar It is consistent.Cylindrical flexible link deflection needs to expend biggish strength, even strong adult male, it is also difficult to primary Property complete a trampoline installation.The application sets the flexible link to more slightly to fade to the thinner rod knot in top by bottom Structure.Specifically, the bar diameter of the bottom of the flexible link is 0.05~3cm referring to Fig. 2, the tapered bar diameter for fading to top is 0.03~2.5cm.In the case where material determines, the bending stiffness of flexible link is directly proportional with bar diameter, the thicker part of bar, bending resistance Rigidity is larger, the thinner part of bar, and bending stiffness is smaller.Such flexibility rod structure is readily bent, and can be realized with less Strength deflects at 30 top of flexible link from natural placement status to 10 center position of cushion, consequently facilitating the flexibility The installation of bar 30 and the cushion 10 also can be realized accessible installation even for the lesser women of strength and children.
Further, the bending stiffness setting of the flexible link 30 is greater than 500N/m, is less than 1200N/m.Preferably, bending resistance Rigidity is set as 1000-1150N/m.The arm strength of average adult male is between 300N-600N.If the bending stiffness of flexible link More than 1200N/m, average adult male will deflect meeting from natural placement status to 10 center position of cushion at the top of flexible link It is very difficult, for women, it can not be achieved substantially.And the bending stiffness of flexible link is lower than 500N, and is difficult to supporting pad The weight of son and the user to bounce on cushion.In addition, the bending stiffness of herein described flexible link 30 be set as 500~ 1200N/m.Reduction in order to compensate for 30 bending stiffness of flexible link caused by lower to 10 support degree of cushion, needs to increase flexibility The radical of bar 30.
The material of current flexible link common on the market is fiberglass pole or carbon fiber.Fiberglass pole has good resistance to Corrosive nature, insulation performance, thermal insulation and high intensity etc..However fiberglass pole hardness is higher, the brittlement phase knot intrinsic with it The defects of conjunction, constitutes low bend resistance outstanding, has not resist bending, wears no resistance, and flexibility is poor.Fiberglass pole is long It phase Reusability and is easily used to crack under low-temperature condition, loses original elasticity, be also therefore broken sometimes, cause trampoline Damage, there are security risks.In addition, according on October 27th, 2017, what international cancer research institution, the World Health Organization announced Glass fibre is listed in 3 class carcinogenic substance inventories in carcinogenic substance inventory, is dangerous material.
Preferably, the preferred aviation aluminium bar of the material of herein described flexible link 30.Aviation aluminium bar material is light, and surface is through oxygen Change processing, wind resistance, anti-pressure ability is stronger than fiberglass pole, while having good intensity, toughness, fatigue resistance and plasticity It is good, the performances such as not easy to break.Even if the pressure of carrying has been more than its upper limit, aviation aluminium bar will not be broken, but increase bending Degree not will lead to trampoline damage, improve the safety of trampoline.
The length of the flexible link 30 is 0.05~1.5m.
Preferably, the length of the flexible link 30 is 0.45~0.6m.
The cross section of the flexible link 30 is circle, and ellipse, triangle, quadrangle, pentagon is or, six deformations or indefinite Shape.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist Under the premise of not departing from present inventive concept, architectural form cans be flexible and changeable, can be with derivative series product.It only makes several Simple deduction or replace all shall be regarded as belonging to present invention scope of patent protection determined by the appended claims.
