Abstract
The utility model discloses a hammer throw protective cage, which comprises a backstop and a light-emitting structure, wherein a plurality of grids and nodes are arranged on the backstop; the light-emitting structure consists of light-emitting diodes, a power supply, a switch and an electric wire; a plurality of light-emitting diodes are fixed to the nodes on the outer side of the backstop uniformly, so that even if a hammer throw is thrown on the backstop, the light-emitting diodes are not damaged; the power supply and the switch are arranged in a control chamber of an athletic field; one part of the electric wire is wound on the backstop and is connected with the light-emitting diodes; and other parts of the electric wire pass through the lower side of the backstop and the ground of the athletic field and are connected with the power supply and the switch in the control chamber of the athletic field. The hammer throw protective cage has a simple structure, can improve an appreciation effect of hammer throw matches, and is suitable for all hammer throws.
Description
Technical field the utility model relates to a kind of cage that protects, the cage that protects with ray structure that especially in the hammer match, uses.
The background technology sports ground is a facility indispensable in the sports.In the hammer match,, need outside throwing circle, to install and protect cage for the safety of competing.The vertical view that protects cage is " U " font.Protect cage and be made up of 7 backstops, every backstop is wide 2.74 meters.Protect the cage A/F and should be 6 meters, be positioned at and throw circle 4.2 meters, the place ahead, the center of circle.The backstop height is 5 meters.Along with the develop rapidly of sports, comprise many sporting events of hammer match, except racing, also have the function of viewing and admiring.But, current this structure of protecting cage, sight still is poor.
Through retrieval, do not retrieve the documents and materials approaching with this patent.
The purpose of summary of the invention the utility model is exactly that a kind of hammer cage simple in structure will be provided, and increases the appreciation effect of hammer match.
In order to achieve the above object, the hammer cage that the utility model provides also has ray structure except having backstop, wherein, many grids and node is arranged on the backstop; Ray structure is made up of light emitting diode, power supply, switch, electric wire; Light emitting diode has many, and light emitting diode evenly is fixed on the node place in the backstop outside, even if hammer is thrown on backstop like this, also can not damage light emitting diode; Power supply and switch all are placed in the control room of sports ground; The part of electric wire is wrapped in and connects light emitting diode on the backstop, and the remainder of electric wire passes backstop below and sport surface, is connected with switch with power supply in the sports ground control room.In addition, the concrete structure that electric wire connects light emitting diode, power supply and switch built-up circuit is a general knowledge, has just repeated no more here.When the utility model uses, only need be in the control room of sports ground console switch, can let light emitting diode send light, make backstop send colour bright.
The hammer cage that the utility model provides has positive effect: except having backstop, also have ray structure, ray structure is made up of light emitting diode, power supply, switch, electric wire, and is simple in structure; Only need be in the control room of sports ground during use console switch, can let light emitting diode send light, make backstop send colour bright, increase the appreciation effect of hammer match, easy and simple to handle, be suitable for all hammer cages.
Description of drawings the utility model will combine accompanying drawing to be further described, please referring to accompanying drawing:
The sketch map of accompanying drawing 1 expression the utility model.
Structure shown in the accompanying drawing 1 comprises: grid 1, node 2, electric wire 3, light emitting diode 4.
The hammer cage that specific embodiment the utility model provides also has ray structure except having backstop, wherein, many grids 1 and node 2 are arranged on the backstop; Ray structure is made up of light emitting diode 4, power supply, switch, electric wire 3; Light emitting diode 4 has many, and light emitting diode 4 evenly is fixed on node 2 places in the backstop outside, even if hammer is thrown on backstop like this, also can not damage light emitting diode 4; Power supply and switch all are placed in the control room of sports ground; The part of electric wire 3 is wrapped on the backstop and connects light emitting diode 4, and the remainder of electric wire 3 passes backstop below and sport surface, is connected with switch with power supply in the sports ground control room.In addition, the concrete structure that electric wire 3 connects light emitting diode 4, power supply and switch built-up circuit is a general knowledge, has just repeated no more here.When the utility model uses, only need be in the control room of sports ground console switch, can let light emitting diode 4 send light, make backstop send colour bright.
The utility model protection domain relates to all changes form recited above.
