Description

A new type of trampoline

Technical field

[0001] The utility model relates to a sports equipment, in particular to a novel trampoline.

Background technique

[0002] A trampoline is a sports facility, the most basic form of which usually includes an elastic cloth fixed to the support frame, so that the elastic cloth supports the hopper on the trampoline, and the same type of net protection is provided around the elastic cloth. Jumper. The user jumps or bounces on the elastic cloth for entertainment and exercise. Prior art boring machine designs incorporate a peripheral frame with a separate support rod sleeve on the frame and an outwardly sloping outer "eight" shaped support foot below the frame. This kind of structure is used in the 吋, because the user constantly jumps on the trampoline, and often there is the action of slamming into the surrounding network, the support rod of the purse net is subjected to the impact force, because the support rod sleeve is separately fixed to the frame Above, all the forces will act on the fixed point. When used between the long rafts, the support rod sleeve will be damaged, so that the lower part of the support rod of the purse sewn will fall off, thus causing injury. The same squat is jumping, because the bounce will produce vertical pressure and lateral pressure, and the pressure in the vertical direction is the largest (because of weight and rebound), which causes the structure of the outer "eight" shaped support feet that are inclined outward. Great damage not only reduces the service life of the support feet, but also reduces the stability of the overall frame structure, which in turn reduces the elastic properties of the trampoline. In addition, the existing design of the elastic cloth and the flexible rod receiving structure adopts a linear outer circumference and an elastic cloth. It is only used as a connecting piece. When the boring machine is used, there is a defect in pressure bearing, especially in the moment of pressure change, flexibility. The contact point between the rod and the elastic cloth will produce strong deformation. When the force is concentrated on the receiving structure, the bearing structure will damage the elastic cloth, and the elastic force will be weakened, which will affect the overall elasticity and stability of the trampoline. The safety performance makes the flexible rod easy to separate from the elastic cloth. The same design of the purse is directly inserted into the support sleeve of the support bar from the bottom up, and the upper end of the support rod is obviously thicker than the middle and lower parts of the support rod, such as set to the ball. Head shape, so that the support rod is inserted into the support sleeve in a bottom-up manner, the support sleeve must be at least slightly thicker than the upper end of the support rod to be inserted, and the result is to support When the rod is hit, it will also come out from the top to the bottom, separating the support rod from the fence, causing the fence to collapse and causing significant injury to personnel. Due to the existence of these defects, how to solve the trampoline frame and the supporting feet Stability, improve the elastic properties of the elastic cloth and not damage, and make the purse net protect the safety of the hopper. This is a problem that the trampoline needs to solve.

[0017] Further, the fence is made of nylon material and has elasticity.

[0018] Further, a protective cover is fixedly mounted on the surrounding net, and the protective cover is disposed corresponding to the supporting sleeve.

[0019] Further, the fence is provided with an L-shaped zipper and can be completely closed from the outside.

Advantageous effects of the invention

Beneficial effect

[0020] According to the utility model, since the outer arc shape of the receiving structure is a circular arc shape, and the outer circular arc degree of the elastic cloth is the same, the matching of the same arc is formed, so that a balanced and symmetrical jumper can be generated, so that relative to the present The designed trampoline has better elastic properties and does not damage the elastic cloth. Because of the action of the limit card and the post, the same stability is increased, and the weakening of the elastic performance is reduced, so that the elastic cloth is not damaged compared with the existing trampoline receiving structure, which is safer and has increased elastic performance and Use daytime, and more stable. Since the male part of the frame arc tube is provided with a rubber sleeve (not shown), that is, a rubber sleeve is arranged between the male head and the female head, and the rubber sleeve can ensure that the whole frame is installed in the same horizontal plane, Guarantee the use of it. The same support rod sleeve is fixed on the curved tube and the vertical connecting sleeve, so that the support rod sleeve is reinforced, and the impact force striking the net is guided to the ground through the support rod, thereby avoiding the support rod sleeve Damage to the cylinder also increases the impact of the fence and is safer. Since the "E"-shaped support legs are disposed at an oblique angle and are connected to the trampoline frame through the vertical connecting sleeve, the intermediate support tube of the "E"-shaped support legs is vertically disposed. This way it can reduce the injury under the momentary pressure shock in the vertical direction. It increases the service life of the trampoline support foot and improves the overall stability of the trampoline, and also plays an important role in improving the elastic properties of the trampoline. Since the bracket top portion of the support sleeve of the purse net is larger than the upper end portion of the support rod, and the first socket portion and the second socket portion are smaller than the upper end portion of the support rod, because the foldable manner is adopted, the installation can be performed after the installation. Inserting the support rod from the top to the bottom into the second socket portion and the first socket portion. When reaching the upper end portion of the support rod, insert the upper end portion of the support rod from the bottom to the top into the bracket top portion, when the socket is installed. Upon completion, the entire support sleeve is integrated and aligned with the support rod. When the impact force is smashed, the anti-backing pad in the pedestal of the support sleeve first prevents the upper end of the support rod from coming off, and then the second sleeve portion ensures that the upper end portion of the support rod is always in the pedestal of the bracket, thereby fixing the circumference The support sleeve on the net will not separate from the support rod, which will provide complete safety.
