The utility model relates to a demonstration device, in particular to a coin throwing demonstration device for probability teaching. The technical problem to be solved is to provide a coin throwing demonstration device for probability teaching, which can throw automatically and evenly. The technical implementation scheme of the utility model is: a probability teaching coin throwing demonstration device, which includes a support seat, a placing seat, a circular block, a swinging rod, a swinging sleeve, a stop block, a connecting rod, an inclined frame, a connecting block, etc.; a placing seat is arranged on the support seat, a circular block is arranged at the front side of the upper part of the placing seat, a swinging rod is arranged at the front side of the circular block, and a swinging sleeve is arranged at the right end of the swinging rod, A block is arranged on the left side of the front side of the upper part of the placement seat, and the block contacts with the swing rod. The utility model sets a swing rod so that when the pressure ball falls on the swing sleeve, it can drive the swing rod to move downward to drive the coin to throw upward, so as to achieve the purpose of coin throwing, and the pressure ball falls from the same height to make the coin throwing force uniform.
【技术实现步骤摘要】
一种概率教学硬币抛掷演示装置
本技术涉及一种演示装置,尤其涉及一种概率教学硬币抛掷演示装置。
技术介绍
在概率教学过程中,常常会讲到硬币抛掷的例子,因而教师需要进行硬币抛掷的演示,而目前教师主要通过人工手动进行抛掷,由于硬币抛掷的例子被使用概率较大,因而教师需要进行多次演示,如此将耗费教师体力;由于抛掷次数较多,通过人工手动抛掷无法掌握每次抛掷的力度等因素均相同,使得演示结果缺乏信服力。
技术实现思路
为了克服人工手动抛掷硬币耗费体力、抛掷力度不均匀的缺点,要解决的技术问题为:提供一种可自动抛掷、抛掷力度均匀的概率教学硬币抛掷演示装置。本技术的技术实施方案为:一种概率教学硬币抛掷演示装置,包括有支撑座、放置座、圆形块、摆动杆、摆动套、挡块、连接杆、斜置框、连接块、轴承座、转杆、摆动卡杆、卡块、挡杆和压球,支撑座上设有放置座,放置座上部前侧设有圆形块,圆形块前侧旋转式设有摆动杆,摆动杆右端设有摆动套,放置座上部前侧左方设有挡块,挡块与摆动杆接触,放置座右侧中部设有连接杆,连接杆上端设有斜置框,斜置框后侧左部设有连接块,连接块上设有轴承座,轴承座上设有转杆,转杆右部穿过轴承座,转杆左端设有摆动卡杆,斜置框前侧左部中间设有卡块,卡块上部与摆动卡杆前部接触,斜置框后侧下部设有挡杆,摆动套内放置有压球。当教师需要使用本装置进行概率教学硬币抛掷演示时,可先将压球放置在斜置框内,再将硬币放置在摆动杆左侧,然后向后旋转摆动卡杆,将摆动卡杆放置在挡杆上,此时压球可从斜置框掉出,压球掉落至摆动套上时,由于 ...
