Abstract
A magnetic levitation spring board belongs to sports apparatuses and aims to achieve stable elastic force and low noise. The magnetic levitation spring board comprises a base, a panel, a spring and a magnet devices, wherein the both the magnet device and the spring are arranged between the base and the panel. The magnet device includes four pairs of magnetic pads respectively arranged on two front sides and two middle sides of each of the base and the panel; each pair of magnetic pads is vertically oppositely arranged; each magnetic pad includes a magnet, a cushion block and a fixing sleeve; both the cushion block and the fixing sleeve are made of non-magnetic-conducting materials; the cushion block is arranged below the magnet; the magnet and the cushion block are sleeved in the base or the panel by the aid of the fixing sleeve; the magnets between each upper magnetic pad and a lower magnetic pad are in like-pole repulsive arrangement, namely an N pole is opposite to another N pole and an S pole is opposite to another S pole; and only one spring for auxiliary support is arranged between the base and the panel among the front pair of magnetic pads and the rear pair of magnetic pads.
Description
Technical field
The utility model relates to a kind of sports apparatus, specifically is the bouncer that a kind of gymnast uses.
Background technology
Springboard is the jump help apparatus that a kind of common Gymnastics Teaching training is used, and has superior jump help performance, when gymnastics technique training or match, often by the elastic force of springboard as the help means, as the training salto etc.Existing springboard adopts spring structure mostly, so also be called " latch plate ".Its weak point is to use spring many, and it is big to step on when jumping mechanicalness noise, particularly use a period of time after mechanical wear serious, spring force weakens, elasticity obviously reduces, it is big that noise becomes.
Summary of the invention
The utility model purpose is exactly the deficiency that overcomes above-mentioned prior art, and a kind of elasticity stable, magnetic suspension springboard that noise is little are provided.
The utility model comprises base, panel, spring and magnet arrangement.Magnet arrangement, spring all are located between base and the panel.Magnet arrangement adopts four pairs of magnetic pads, is separately positioned on the front part sides and the both sides, middle part of base and panel, and every pair of magnetic pad position is oppositely arranged up and down; The magnetic pad comprises flat thin magnet, cushion block and fixed cover, and cushion block and fixed cover all adopt non-magnet material to make; Be provided with cushion block below the flat thin magnet, flat thin magnet and cushion block are by being fixedly set on base or the panel.Flat thin magnet between two magnetic pads is the setting of same polarity rejection-like up and down, and promptly N is extremely to the N utmost point, and S is extremely to the S utmost point.Between base in the middle of the two pairs of magnetic pads in front and back and panel, only be provided with a spring that plays the supplemental support effect.Distance H between two magnetic pads is tried to achieve according to following formula up and down: H=3L/40.
In the formula: H is the distance between two magnetic pads up and down, and L is the distance of this magnetic pad center line to base and panel joining.The magnetic field intensity of flat thin magnet is 3000-6000 Gauss.
Because up and down the flat thin magnet between two magnetic pads is the setting of same polarity rejection-like, when panel produces pressure, two magnetic pads near the time can produce increasing repulsive force, thereby panel is upspring.Because two magnetic pads are in contactless state all the time in using, so magnetic pad noise is little, not fragile, the life-span is long.The utility model replaces spring with magnet arrangement, can effectively overcome the deficiency that original springboard mechanicalness noise is big, mechanical wear is serious, and good springiness, spring is felt, the sense of suspension is arranged, help sportsman's performance, the function of springboard is reduced.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, base, 2, flat thin magnet, 3, cushion block, 4, fixed cover, 5, panel, 6, spring, 7, go up the magnetic pad, 8, magnetic pad down, 9, the panel rotating shaft.
The specific embodiment
The timber that base 1 usefulness is solid or metallic plate are made, and panel 5 can be with firm and resilient batten amalgamation, for strengthening its elasticity and firm degree colligation bamboo plate again on batten.Panel 5 also available metal plate is made.Flat thin magnet 2 adopts ndfeb disk, and fixed cover 4 is the stainless steel cover cap, is fixed on base 1 top or panel 5 belows by screw, and flat thin magnet 2 and cushion block 3 are fixed on fixed cover 4 the insides together, can prevent that flat thin magnet 2 from use damaging.
When utilizing formula H=3L/40 to calculate, L is the distances of these magnetic pad 3 center lines to panel rotating shaft 9.
The error range of distance H should be in 15% between two magnetic pads 7,8 up and down.
Cushion block 3 has two kinds.A kind of is cylindrical shape, and surface and bottom surface all are flat; Another kind is a wedge shape, and the surface is flat, and the bottom surface tilts.The cushion block upper surface is flat in the last magnetic pad 7, and the bottom surface tilts.The upper surface of cushion block and bottom surface all are flat in the following magnetic pad 8.The fixed cover plane of two magnetic pads 7,8 is parallel or approximately parallel like this, up and down.
Cushion block can be the same with cushion block in the following magnetic pad 8 in the last magnetic pad 7, and upper surface and bottom surface all are flat.Like this, fixed cover 4 planes of last magnetic pad 7 are parallel or approximately parallel with panel 5 planes; The fixed cover plane of following magnetic pad 8 and base 1 plane parallel or approximate parallel.At this moment, when utilizing formula H=3L/40, the H in the formula is the distance between two magnetic pad center lines up and down, and L is the distance of this magnetic pad center line to base and panel joining.
