Abstract

The invention discloses a throwing circle, comprising an illuminating structure besides an iron circular edge and ground in the circle. The illuminating structure consists of a transparent retainer ring, a plurality of lamps, a switch and an electric wire, wherein the circular transparent retainer ring is made of transparent hard plastic or toughened glass, is arranged inside the iron circular edge; a cavity is arranged under the transparent retainer ring; the lamps are fixed on the inner wall of the cavity; the switch is arranged in a control room of a playground, and is connected to a power supply; partial electric wire is connected with the lamps, while the rest is connected with the switch in the control room of the playground after passing through the ground of the playground. The throwing circle has simple structure, due to that the lamps can emit colorful light through the transparent retainer ring only by pressing down the switch in the control room and connecting the circuit during use, so that the viewing effect of shot and other games can be increased. The invention is simple and convenient for operation, and is applicable to all throwing circles.

Description

Throw circle

Technical field the present invention relates to a kind of throwing circle, especially the throwing circle with ray structure that uses in shot or discus match.

Background technology shot or discus all are the ancient events in the Olympic Games, and to objects such as prey throwing stones, development develops into sports gradually when originating from the mankind of primitive society hunting.Matches such as shot have all been done clear and definite regulation to throwing circle: the sportsman stands in throwing circle and begins to throw; Throwing the circle periphery is the limit of iron edge, and 6 millimeters thick are arranged, and whitewash on the top; When throwing, the sportsman can not contact the top on iron limit or throw circle ground in addition; 2,135 meters of the throwing loop diameters of shot and hammer, the throwing circle of discus is slightly bigger, 2.5 meters of diameters; The interior ground of circle is by cement or have similar hardness to constitute by anti-skidding material again, and its height is a little less than ground level; It is long that a wooden baffle plate 1.21-1.23 rice is being put in the dead ahead of circle for shot putting, and it is used for preventing that the sportsman from skidding off outside the circle; The sportsman can bump the inboard of baffle plate, but can not bump the top of baffle plate.On the other hand,, comprise many sporting events of shot put or discus, except racing, also have the function of viewing and admiring along with the develop rapidly of sports.But, this structure of current throwing circle, its sight still is poor.

Chinese patent CN2834633 number disclosed " shot field metal stop board " patent (application number: 200520099913.X), by plate body, place the reinforcement gusset that has passage in the plate body and on it, be welded on the fixed head that has the hole that cooperates with hold-down screw on its of two ends, plate body bottom surface and form; Wherein, have several passages on the both sides panel of plate body, the radius of plate body arc surface is with the circle for shot putting radius, and its lap is rectangle.The weak point of this patent is: though have sturdy and durable, true-to-size characteristics, still can not allow and throw circle increase spectators appreciation effect on sense organ in the discus throw match.

In addition, do not retrieve the documents and materials more approaching with this patent.

Summary of the invention purpose of the present invention is exactly that a kind of throwing circle simple in structure will be provided, the appreciation effect of matches such as increase shot.

In order to achieve the above object, throwing circle provided by the invention the ground, also has ray structure in having iron circular edges, circle, and wherein, ray structure is made up of transparent back-up ring, lamp, switch, electric wire; Transparent back-up ring is made by transparent rigid plastics or safety glass, and transparent back-up ring is ring shape, and transparent back-up ring is placed in the inboard of iron circular edges, and there is individual cavity the below of transparent back-up ring; Lamp has many, and lamp is fixed on the cavity inner wall; Switch is placed in the control room of sports ground and connects power supply; The part of electric wire connects lamp, and the remainder of electric wire passes sport surface and is connected switch in the sports ground control room.In addition, the particular circuit configurations that electric wire connects lamp, switch is a general knowledge, has just repeated no more here.When the present invention uses, only need press switch in the control room, connect circuit, lamp can see through transparent back-up ring and send colour bright.

Throwing circle provided by the invention has positive effect: the ground, also have ray structure in having iron circular edges, circle, ray structure is made up of transparent back-up ring, lamp, switch, electric wire, and is simple in structure; Only need press switch in the control room during use, connect circuit, lamp can see through transparent back-up ring and send colour bright, the appreciation effect of matches such as increase shot, and easy and simple to handle, be suitable for all throwing circles.

Description of drawings the present invention will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:

Accompanying drawing 1 expression schematic diagram of the present invention.

Structure shown in the accompanying drawing 1 comprises: iron circular edges 1, transparent back-up ring 2, ground 3 in the circle, lamp 4, cavity 5, sport surface 6, electric wire 7.

Specific embodiment throwing circle provided by the invention the ground 3, also has ray structure in having iron circular edges 1, circle, wherein, ray structure is made up of transparent back-up ring 2, lamp 4, switch, electric wire 7; Transparent back-up ring 2 is made by transparent rigid plastics or safety glass, and transparent back-up ring 2 is ring shape, and transparent back-up ring 2 is placed in the inboard of iron circular edges 1, and there is individual cavity 5 below of transparent back-up ring 2; Lamp 4 has many, and lamp 4 is fixed on cavity 5 inwalls; Switch is placed in the control room of sports ground and connects power supply; The part of electric wire 7 connects lamp 4, and the remainder of electric wire 7 passes the switch in the control room that sport surface 6 is connected sports ground.In addition, the particular circuit configurations that electric wire 7 connects lamp 4, switch is a general knowledge, has just repeated no more here.When the present invention uses, only need press switch in the control room, connect circuit, lamp 4 can see through transparent back-up ring 2 and send colour bright.

Protection domain of the present invention relates to all changes form recited above.
