Abstract
The invention relates to a magnetic bouncing board belonging to the field of sports apparatus and aiming at achieving the purposes of stable elasticity and low noises. The magnetic bouncing board comprises a base, a panel, a spring and a magnet device, wherein the magnet device and the spring are both arranged between the base and the panel; the magnet device adopts four pairs of magnetic cushions which are respectively arranged on the base and at both sides of the front part and two sides of the middle of the panel, and every pair of magnetic cushions are oppositely arranged top and bottom; each magnetic cushion comprises a magnetic sheet, a cushion block and a fixed sleeve, wherein the cushion blocks and the fixed sleeves are all made of non-magnetic materials; the cushion blocks are arranged below the magnetic sheets, and the magnetic sheets and the cushion blocks are arranged on the base or the panel through the fixed sleeves; the magnetic sheets positioned between the upper cushion block and the lower cushion block are arranged in a like pole repelling way, that is to say, an N pole is opposite to an N pole, and an S pole is opposite to an S pole; and only one spring which plays an auxiliary supporting role is arranged between the base positioned at the middle of the front magnetic cushion and the rear magnetic cushion and the panel.
Description
Technical field
The present invention 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 object of the invention is exactly the deficiency that overcomes above-mentioned prior art, and a kind of elasticity stable, magnetic bouncing board that noise is little are provided.
The present invention includes 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 present invention 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 a structural representation of the present invention.
The specific embodiment
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 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.
