A waterproof performance testing device for pocket watch

Abstract

The invention relates to the technical field of watch detection, and discloses a waterproof performance detection device for pocket watches, which includes a bottom plate and a bracket, a container is placed above the bottom plate, a movable rod is connected to the bracket, and a hanging rod is connected to the lower end of the movable rod. A pocket watch is connected to the rod, and a collar is sleeved on the outside of the bracelet of the pocket watch. The right side of the collar is connected to a moving rod, and the right end of the moving rod is connected to a connecting sleeve. The connecting sleeve is sleeved in the middle of the arc bow, and the upper end of the arc bow is fixedly connected There is an upper screw block, and the lower end of the arc bow is fixedly connected with a lower screw block, and both the upper screw block and the lower screw sleeve are connected on the rotating shaft. The waterproof performance testing device for pocket watches can change the time that the pocket watch is submerged in water during the movement cycle of moving the rod, and can record and observe the times of pocket watch submersion without deliberate artificial statistics, and has the ability to control the unit time Immersion time, and the advantage of being easy to control the number of immersions.

Description

technical field [0001] The invention relates to the technical field of watch detection, in particular to a waterproof performance detection device for pocket watches. Background technique [0002] A clock is a timing device and a precision instrument for measuring and indicating time. Clocks are usually distinguished by the size of the internal machine. According to international practice, a movement with a diameter of more than 80 mm and a thickness of more than 30 mm is a clock; a diameter of 37 to 50 mm and a thickness of 4 to 6 mm is called a pocket watch; a diameter of less than 37 mm is a watch; a diameter of less than 20 mm or a movement A watch with a heart area of ​​no more than 314 square millimeters is called a female watch. The watch is one of the smallest, strongest and most precise machines ever invented by man. [0003] The waterproof performance of clocks and watches is an important performance of watches and clocks. Most of the existing testing devices fo...
