Description
Technical field
The present invention relates to a kind of sports tournament apparatus, the apparatus particularly used when a kind of doump log and tug-of-war.
Background technology
Doump log match is that two or several sportsman utilize related equipment, carries out a kind of form of play mutually to thruster tool in the playing area of regulation.At present, the match instrument of doump log match no standard.In competition game, usually adopt the apparatus that log pile is competed as doump log, during match, the hand-held log pile of both sides team member pushes away mutually, whether can push through boundary line, river, center evaluate decision of a game according to sportsman.The deficiency pushing away log pile match existence is like this: if having a side, direction to pushing hard in both sides sportsman during match, opponent can be made to fall or fall down.Make result of the match contingency comparatively large like this, match not only can be made to lack fairness, also can cause injury gained in sports to sportsman; Tug-of-war equipment is usually the rope that there is marker a centre, and during match, the both sides that two teams sportsman holds tug-of-war rope pull at.Carrying out tug-of-war Problems existing with this equipment is: 1. judge that result of the match exists error by referee's eyes, and as whether tug-of-war starts front center marker at central point, during match, whether center marker arrives boundary line and all there is error; 2. the unexpected hand of a side sportsman decontrols tug-of-war rope, the several sportsman of the opposing party can be made to fall down, cause injury gained in sports; 3. a side sportsman firmly pulls out to side suddenly, can make the opposing party's athletes ' body center of gravity disequilibrium or fall down injured, thus games results are affected.
Summary of the invention
The present invention is intended to overcome above-mentioned existing problems, provides a kind of safe and reliable match device, and this device both can be used for carrying out doump log match, can be used for again carrying out tug-of-war.
The technical solution adopted in the present invention is: a kind of doump log and tug-of-war device, it is characterized in that: this device is grouped into by railcar and undercarriage portion, wherein, the agent structure of described railcar comprises compartment, the left and right sides, upper end, described compartment is fixedly connected with one end of four pull bars, the other end of two pull bars in every side is fixedly connected with the two ends of holding rod, link is provided with in the middle part of described holding rod, described car bottom is provided with four wheels, described compartment is provided with locator before bottom, both sides, bottom, described compartment are respectively equipped with pressure switch, battery is provided with in described compartment, upper end two, described compartment middle side part is respectively equipped with indicator lamp, described underframe part agent structure comprises two tracks being provided with several installation screws bottom it, the two ends of described two tracks are fixedly connected with riser lower end respectively, the baffle plate that its underpart is provided with two castors is respectively equipped with inside the riser of described two ends, be respectively equipped with spring between described two ends riser and baffle plate to be connected by screw-nut, two inner sleeves being provided with the locating hole corresponding with locator in the middle part of it are each passed through bottom, described compartment and are fixedly connected with riser upper end, two ends with two end-stopping plate upper ends, described compartment can contact with baffle plate under external force, and described pressure switch is opened when described compartment contacts with baffle plate, lights indicator lamp.
The isosceles trapezoid that the connection of the left and right sides, upper end, compartment of the present invention and four pull bars and two holding rods is arranged symmetrically, one end of four poles is separately fixed on compartment, the other end is separately fixed on pull bar, to strengthen the steadiness that two isosceles trapezoids connect.
Link of the present invention is connected with hook, and described hook is connected by fixture with tug-of-war rope, thus meets doump log and tug-of-war two kinds of match requests.
Four wheels of the present invention and four castors are inlayed with described two tracks respectively and are connected.
Front and back, compartment of the present invention is respectively equipped with center board.
Compared with prior art, structure is simple, safe and reliable, easy to use in the present invention.The railcar of this device can only move in orbit, even if doump log or tug-of-war sportsman side direction firmly also can not bring impact to opponent.Undercarriage portion divides the baffle plate of setting and spring that compartment can be made to push away or move to two ends to be cushioned, effectively can prevent the side sportsman from letting go suddenly and cause the drawback of injury gained in sports to the opposing party sportsman.The pressure switch that bottom, compartment is arranged can control the closedown of indicator lamp, and when baffle plate is touched in bottom, compartment, the indicator lamp of side can be lighted, indicator lamp conveniently judges result of the match.Link on holding rod and the hook on tug-of-war rope facilitate the handling of tug-of-war rope.In a word, adopt this device to carry out doump log or tug-of-war, can effectively improve match facility, make match fairer and more reasonable, referee judges science, accurately more to result of the match.Thus, strengthen athletic participation enthusiasm, improve match interest, decrease injury gained in sports, be convenient to sportsman and play optimum level, be convenient to spectators and enjoy more excellent doump log and tug-of-war.
