As shown in fig. 4 and 5, in order to keep a certain gap between the periphery of the upper end surface of the lower conductive plate and the periphery of the lower end surface of the upper conductive plate, the insulating assembly 24 is wrapped by a spherical insulating pad 241 and a rubber elastic washer 242, the middle part of the lower conducting strip 22 is provided with a positioning lug 222 which protrudes upwards, the lower end surface of the spherical insulating pad 241 is provided with a positioning groove which is concave upwards and matched with the positioning lug 222, the upper end surface of the spherical insulating pad 241 is spherical, the middle part of the lower end surface of the upper conducting strip 23 is provided with a spherical concave surface matched with the upper end surface of the spherical insulating pad 241, an avoiding hole for avoiding the spherical insulating pad 241 is arranged in the middle of the rubber surface elastic washer 242, the spherical insulating pad 241 is located in the avoiding hole of the rubber surface elastic washer 242 and is clamped and fixed between the positioning bump 222 and the spherical concave surface of the upper conducting strip 23, two end faces of the rubber-faced elastic washer 242 are respectively bonded and fixed with the upper end face of the lower conducting strip 22 and the lower end face of the upper conducting strip 23.

As shown in fig. 3-5, the insulating base 21, the lower conducting strip 22, the upper conducting strip 23, the insulating assembly 24, and the elastic insulating cover 25 are all circular rotating members, a circular cavity that is concave upward is disposed in the middle of the lower end surface of the elastic insulating cover 25, the lower conducting strip 22, the upper conducting strip 23, and the insulating assembly 24 are all located in the circular cavity, and the periphery of the lower end surface of the elastic insulating cover 25 is fixedly bonded to the upper end surface of the insulating base 21.

The working principle of the embodiment is as follows: firstly, combining a linear ground pad strip 11 and a connecting strip 12 according to the size of the existing open ground, then installing a scoring contactor 2 on the linear ground pad strip 11, connecting a counting device 3, and counting one point by the counting device 3 when an upper conducting strip 3 and a lower conducting strip 2 are contacted once. The win-or-lose of the match is judged according to the score within the specified time, and the concrete operation is that the players roll the scoring contactors 2 on the competition field by the front wheels and the rear wheels of the riding equipment in the riding process, and each time the players roll different positions on the scoring contactors 2, different scores are obtained respectively, specifically, two scores can be obtained by pressing the middle of the scoring contactors 2, and only one score can be obtained by pressing the edge of the scoring contactor 2. As shown in fig. 6 and 7, when the wheel passes through the center of the contactor, the upper conductive plate and the lower conductive plate contact twice, as shown in fig. 7a, when the wheel just contacts the scoring contactor, the wheel presses the edge of the rear portion of the upper conductive plate 23, the rear portion of the upper conductive plate 23 compresses the rubber surface elastic washer 242 downwards to deform the rubber surface elastic washer, the edge of the rear portion of the upper conductive plate 23 contacts the upper surface of the lower conductive plate 22, the circuit is closed once, and one minute is accumulated automatically in the system. When the wheel continues to roll to the position shown in fig. 7b, the lowest part of the wheel is located at the middle of the contactor, and at this time, the upper conducting strip 23 with the pressed middle part is supported by the spherical insulating pad 241 below the upper conducting strip 23, and the rubber surface elastic washer 242 cannot be compressed downwards, and at this time, the upper conducting strip 23 is not in contact with the lower conducting strip 22, and the circuit is disconnected. When the wheel continues to roll to the position shown in fig. 7c, the wheel presses the edge of the front portion of the upper conductive plate 23, the front portion of the upper conductive plate 23 compresses the rubber-faced elastic washer 242 downward to deform the rubber-faced elastic washer, the edge of the front portion of the upper conductive plate 23 touches the upper surface of the lower conductive plate 22, and at this time, the circuit is closed again, and the system is counted one minute again. The wheel then continues to roll forward away from the contactor and the upper conductive plate 22 returns to its original position under the spring force of the elastomer washer 242. Namely, when the wheel is pressed from the middle of the contactor, the circuit is closed twice, and two parts are obtained, namely two parts are connected. As shown in fig. 8, when the wheel is pressed from the non-center of the contactor, the edge of the upper conductive sheet 22 is always in contact with the upper surface of the lower conductive sheet 23 during the pressing process until the wheel is driven away, the line is closed only once during the pressing process, and the system is only one-minute accumulated. The front wheel and the rear wheel of each vehicle respectively roll over the contactor, and the two-time connection of the front wheel and the rear wheel of each vehicle has the opportunity of two-time connection, namely the two-time connection, and the two-time connection is full of 4 minutes. The design of this score contactor structure makes the match have more interest and sight, has solved the score difficult problem in the present bicycle class match, and the range of application is extensive, easily popularizes and applies.

As shown in fig. 9, the riding competition system provided by the embodiment includes a portable riding competition field, and is characterized in that: still include the equipment of riding, the equipment of riding includes bicycle 4 and installs on bicycle 4 and with bicycle rear wheel matched with snail car 5. The ox vehicle 5 can adopt a single-wheel double-cylinder speed reducer disclosed in patent 201611256691.7, a single-wheel double-wheel speed reducer disclosed in patent 201611256729.0, a single-wheel single-roller speed reducer disclosed in patent 201611258640.8, a single-wheel bicycle speed reducer disclosed in patent 201611258711.4, a portable bicycle speed reducer disclosed in patent 201510212136.3 and a two-stage transmission bicycle speed reduction training device disclosed in patent 201510211896.2, a two-stage drive bicycle reduction training device provided with a rear wheel disclosed in patent 201510212363.6, a two-stage drive bicycle reduction training device provided with a pull rod disclosed in patent 201510212020.X, a two-stage drive bicycle reduction training device provided with a pull rod disclosed in patent 201510211999.9, a direct drive bicycle reduction training device provided with a rear wheel disclosed in patent 201510212332.0, a bicycle reduction training device provided with a rear wheel disclosed in patent 201510212257.8, and a bicycle reduction training device disclosed in patent 201510212310.4.
