Abstract

The utility model discloses an automatic-timing chessboard. The utility model comprises a case body, wherein the top of which is open; the chessboard is arranged in the case body; one side of the case body is provided with two timers and a counter; a return spring is arranged between the bottom surfaces of four corners of the chessboard and the inner wall of the case body; the bottom surface of the case body is provided with a pressure contact switch; the central position of the bottom surface of the checkered is provided with a rod body which is touched and pressed on the pressure contact switch; the rod body is a conical body, and the cone tip part is in contact with the pressure contact switch; the timers are electrically connected with the pressure contact switch through a control circuit. The automatic timing chessboard is used for playing chess, when both parties who play chess run out of one step, a timing clock does not need to be pressed once by hand to convert and accumulate; the use is convenient, the utility model can not cause players to disperse attention, and thus, the players can play chess intently; the utility model can also automatically count the respective time and chess going step number of both parties who play chess. The utility model has the advantages of convenient fabrication and low cost; the utility model is suitable for Chinese chess, chess, go set chess, land fight chess, etc.

Description

Chessborad having automatic timing device

Technical field

The utility model relates to a kind of chessboard, especially a kind of chessboard with self-clocking tally function.

Background technology

People use more chess that Chinese chess is arranged at present, chess, go etc., the used chessboard of these chesses has papery, colloid or wooden chessboard, itself does not have the chronoscope number system these chessboards, can not add up both sides' time spent and the row chess step number separately of playing chess, need come timing with two manual elapsed time clocks during formal competition, by on-the-spot supervision of referee and record row chess step number, the every step chess that played of the both sides that play chess all needs go to change by an elapsed time clock with hand, accumulative total, use very inconvenient, and cause chess player's energy to disperse easily, can not intently play chess.

Summary of the invention

The technical problems to be solved in the utility model provides the Chessborad having automatic timing device that does not need manually to control clock in a kind of process of playing chess and can finish both sides' timing automatically.

For solving the problems of the technologies described above, the utility model comprises the box body of open top, be placed with chessboard in the box body, its design feature is: the side at box body is equipped with two timers, be provided with return spring between the bottom surface at four angles of chessboard and the inboard wall of cartridge, box bottom is provided with the pressure contact-making switch, is provided with the body of rod that presses the pressure contact-making switch in the center of chessboard bottom surface, and timer is electrically connected with the pressure contact-making switch through control circuit.

Side at box body also is equipped with the counter adjacent with timer, and counter is electrically connected with timer, pressure contact-making switch through control circuit.

The described body of rod is a bullet, and its cone tip part contacts with the pressure contact-making switch.

Operation principle of the present utility model is: all have on the timer sum counter and independently adjust button, open counter SW key K3 during use, make counter in running order, and pass through K5, the K6 button is with timer R1, R2 places opposite duty, as a timer R1 work (side of the chess of going ahead of the rest, red), timer R2 closes, when a side of chess begins in advance, push chessboard, the instantaneous turning circuit of button K4 then, this moment button K5, K6 (for non-locking press button) has all disconnected, and electric current flows out via the positive pole of clock 1 power supply, arrives K2 through K4, arrive the negative pole of clock 2 power supplys again by K2, positive pole by clock 2 power supplys arrives K1, arrives the negative pole of clock 1 power supply at last, forms the primary current loop.In this process, electric current flow through simultaneously K1, K2, and changed the duty of timer R1, R2, timer R1 are become by work and close, and timer R2 becomes work by closing, and realizes the alternately timing of timer.Simultaneously, among the counter R3 once electric current flow through, cause that rolling counters forward changes.When beginning, pushes by the opposing party row chess chessboard, the instantaneous turning circuit of button K4 then, and current direction is the same, and just timer R1 becomes work by closing, and timer R2 is become by work and closes, and rolling counters forward changes equally, successively circulation.

From the above mentioned, when using this Chessborad having automatic timing device to play chess, the both sides that play chess are every played a step chess need not with hand go by elapsed time clock change, accumulative total, easy to use, can not cause chess player's energy to disperse, the chess player can intently play chess, one side's Clock enable, then the opposing party's clock stops, so alternately, reach the purpose of self-clocking, can add up the time spent separately the both sides that play chess automatically.And on chessboard, be provided with counter, and the both sides' that play chess capable chess step number can be automatically recorded, need not special messenger's record; The body of rod adopts bullet, and its cone tip part contacts with the pressure contact-making switch, can guarantee no matter in which position of chessboard to begin, the pressure contact-making switch can both be connected, reliable operation.It makes simple, and cost is low, is applicable to Chinese chess, chess, go, land warfare chess etc.
