Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of physical education teaching, and more specifically to a running timer. Background Art
[0002] Timers are used to record the performance of athletes in various track and field competitions, including the competition time or distance of short-distance, middle-distance and long-distance events. Timers are used to time the start time of athletes to ensure the fairness and accuracy of the competition, and record the time when athletes arrive at the finish line to determine the ranking of the competition results. Through the use of timers, track and field competitions are conducted more standardized and accurately, and also provide important data support for athletes' training and performance.
[0003] When the user is in use, the existing timer is often hung around the neck or held in the hand by a lanyard. When the user is in fast motion, the timer will vibrate to a large extent and may even fall out of the hand. The watch movement of the existing timer is mostly fitted inside the shell, and the shell is not convenient for absorbing impact force. When vibrating and impacting, the watch movement and the shell will absorb a large amount of impact force synchronously, which may cause damage to the watch movement and reduce the service life of the timer. When carrying, the existing timer is often hung around the neck by a lanyard. When in use, the lanyard is mostly removed from the neck and the timer is held in the hand. However, the lanyard of the existing timer is mostly fixedly installed on the watch body. When holding the timer, due to the presence of the lanyard, it may be entangled with the watch body when running, thereby blocking the watch body, affecting the observation time, and causing errors in the final result.

[0030] The outer surfaces of the two sets of buttons 12 are both provided with waterproof pads, and the material of the waterproof pads is rubber. Figure 3 As shown, waterproof pads are provided on the outer surfaces of the two groups of buttons 12, and the waterproof performance of the device can be improved by the toughness and sealing properties of the rubber material itself.
[0031] The upper surface of the housing 21 is provided with a circular hole, and the circular hole is provided with two groups. The two groups of buttons 12 are respectively inserted into the inside of the two groups of circular holes. The diameter of the waterproof pads provided on the outer surface of the two groups of buttons 12 is larger than the diameter of the two groups of circular holes. The inside of the housing 21 is provided with a buffer pad, and the buffer pad is provided with multiple groups, and the multiple groups of buffer pads are all made of rubber. The outer surface of the movement 11 is attached to the outer surface of the buffer pad.
