Abstract
The utility model relates to an oblique spring springboard, which comprises a bottom plate and a pedal which is connected with one end of the bottom plate, a spring is arranged between the bottom plate and the other end of the pedal, which is connected with the bottom plate, and the upper end and the lower end of the spring are respectively fixedly connected with the bottom plate and the pedal. The utility model has the characteristics that a conical spring is used, the spring is obliquely arranged between the bottom plate and the pedal, compared with a spring which is vertically arranged, the elastic direction of the oblique spring is backward oblique, thereby increasing the elasticity of the springboard under the situation that the materials and specification of the springboard are not changed.
Description
Technical field
The utility model belongs to the sports movement apparatus technical field, relates to the beat board that uses in a kind of gymnastic, is specifically related to a kind of beat board of tilting spring.
Background technology
In gymnastic, the upper plate take-off is a sport technique segment of doing the most critical of action in horse-vaulting, and the quality of upper plate take-off technology is to the conclusive effect of having played of finishing of horse-vaulting difficult part.Take-off depends on uses beat board to finish, and therefore, the structure of beat board and performance are very important key factors that influences the performance of horse-vaulting technology.
The development of beat board experienced by wooden set square to " S " template, again to the evolution process of latch plate.The springboard of existing use, its spring are perpendicular to the base plate arrangement, and the sportsman is pedaled oblique the exerting oneself of plate action.Therefore, the vertical stress component when only pedaling plate could play compression to spring, and horizontal component has then lost, and the elastic force of spring is given full play of.
Summary of the invention
The purpose of this utility model provides a kind of oblique spring springboard, and spring is tilting, can make vertical stress component when pedaling plate and horizontal component simultaneously with the mode of making a concerted effort to spring compression work, the elastic force of spring is fully used.
The technical scheme that the utility model adopted is, oblique spring springboard, comprise base plate, the pedal that is connected with base plate one end, be provided with volute spring between the other end that base plate and pedal connect, fixedlying connected with pedal with base plate respectively in the two ends up and down of spring, is characterized in, spring adopts volute spring, volute spring is obliquely installed between base plate and pedal, and it is oblique towards direction of take off.
Be fixed with cushion block between spring and the base plate, the end face that cushion block is fixedlyed connected with spring is the inclined plane, and its inclined plane is towards direction of take off.
Oblique spring springboard of the present utility model is taked the form of tilting spring in the beat board, can make the direction of spring compression and pedal the direction that plate exerts oneself to tend to consistent as much as possible, accept to greatest extent pressing plate to energy, increased the elasticity of springboard.
Description of drawings
Fig. 1 is the version schematic diagram of existing beat board;
Fig. 2 is the structural representation of a kind of embodiment of the utility model springboard;
Fig. 3 is the three-dimensional effect diagram of Fig. 2.
Among the figure, 1. base plate, 2. pedal, 3. spring, 4. cushion block.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Driven angle of mechanics sees that the take-off process that uses latch plate to do the horse-vaulting action is actually the process of a power conversion.For beat board, the take-off technology can be divided into pressing plate and two links of take-off:
(1) pressing plate.The energy that the sportsman brings into play by the energy pedaling plate human body is obtained in run-up and body muscular exertion is stored in the springboard, and springboard is accepted this energy and converted elastic potential energy to the form of spring compression and plate facial disfigurement.The spring compression is many more and the plate facial disfigurement is big more, and then energy stored is just big more.
(2) take-off.When the pressing plate process boils over, springboard plate shape and compressed spring will reduce, and elastic potential energy just is released, and act on human body in the mode of elastic force.By means of elastic force, the sportsman finishes the action of the pre-flight of horse-vaulting.
The springboard of existing use as shown in Figure 1, comprises base plate 1 and pedal 2, pedal can be the plane also can be curved surface, between base plate 1 and pedal 2, spring 3 is set.Because spring 3 is vertically disposed between base plate 1 and pedal 2, and the sportsman is pedaled oblique the exerting oneself of plate action.Therefore, the vertical stress component when only pedaling plate could play compression to spring, and horizontal component has then lost.
Structure of the present utility model such as Fig. 2, shown in Figure 3, adopt volute spring, the base plate 1 of beat board and the spring 3 between the pedal 2 are obliquely installed, can on base plate 1, place the cushion block 4 that end face is the inclined plane, one end of spring 3 is fixed on the cushion block 4, the other end of spring 3 is fixed on the bottom surface of pedal 2, and the inclination that makes spring 3 is towards people's direction of take off.
Springboard of the present utility model is tilting with spring, as much as possible with the direction of spring compression with pedal the direction that plate exerts oneself and be consistent, accept to greatest extent pressing plate give with energy, compare with the spring of positioned vertical, tiltedly the elastic force direction of spring is to oblique rear, thereby under the situation constant at the springboard material, that specification is constant, increased the elasticity of springboard.
Claims (2)
1. oblique spring springboard, comprise base plate (1), the pedal (2) that is connected with base plate (1) one end, be provided with spring (3) between the other end that base plate (1) and pedal (2) connect, fixedly connected with pedal (2) with base plate (1) respectively in the two ends up and down of spring (3), it is characterized in that, described spring (3) adopts volute spring, and the spring of taper (3) is obliquely installed between base plate (1) and pedal (2), and it is oblique towards direction of take off.
2. according to the described oblique spring springboard of claim 1, it is characterized in that be fixed with cushion block (4) between described spring (3) and the base plate (1), the end face that cushion block (4) is fixedlyed connected with spring (3) is the inclined plane, and its inclined plane is towards direction of take off.
