Description

Technical Field

[0001] This utility model relates to the field of watch strap testing technology, specifically a watch strap tensile testing device. Background Technology

[0002] A wristwatch, also known as a wristwatch, is a portable timepiece worn on the wrist. Common materials for watch straps include leather, rubber, nylon, and stainless steel. The manufacture and production of watches are based on springs, which can tighten and store energy, and then slowly release it to power the watch's internal mechanism and hands, thus displaying the time. This spring mechanism inside the watch is called the mainspring. A watch consists of a watch head, strap, and clasp. The watch head components include: movement, case, case back, crystal, dial, hands, crown (also called pusher, used for adjusting the time), and pushers (required in some watch models). Watches utilize a constantly oscillating system with a constant period as a standard. If the time (vibration period) required for the oscillation system to complete one full oscillation of the watch is known, and the number of oscillations is calculated, then the time elapsed after so many oscillations is equal to the vibration period multiplied by the number of oscillations. A balance wheel and hairspring mechanical watch uses a balance wheel and hairspring as its oscillation system. The balance wheel 1 is fixed to the balance shaft 2, and the upper and lower journals of the balance shaft are housed in bearings, allowing it to rotate around the bearings. One end of the hairspring component 3 is fixed to the balance shaft, and the other end is fixed to the bridge. Due to the elastic deformation of the hairspring, the motion of the balance wheel changes from rotation to reciprocating motion. During oscillation, the balance wheel and hairspring system is affected by the friction of the bearings, air resistance, and the internal friction of the hairspring, causing the amplitude of the oscillation to gradually decrease until it stops. To ensure continuous oscillation without attenuation, the balance wheel and hairspring system must be periodically replenished with energy; that is, the watch must have a power source. This periodic replenishment of energy to the oscillation system is achieved through a special mechanism—the escapement mechanism. The escapement mechanism also calculates the number of oscillations of the balance wheel and hairspring system. Therefore, the balance wheel and hairspring system and the escapement are the key components of a mechanical watch.

[0003] Electronic watches have a timing error of less than one second per day when the temperature is between 25 and 28°C. However, when the temperature drops below 0°C or exceeds 50°C, they will lose two seconds per day. Furthermore, the LCD screen will turn black at temperatures as high as 60°C, and will lose its display function when the temperature drops below 0°C. Therefore, in winter, electronic watches must be worn on the wrist, relying on the body's temperature to maintain normal timekeeping. Additionally, excessively high or low temperatures can cause battery leakage and corrosion of the movement. Electronic watch batteries generally last for more than a year; however, the backlight consumes a lot of power—one second of illumination consumes the equivalent of more than an hour of timekeeping. When the battery is low, the backlight will dim, or the digital display may dim or even disappear when the watch is on. If you lack watch repair skills, you should take your watch to a watch repair shop for installation. Also, battery specifications are not standardized; many different brands and types of batteries exist, and you cannot use just any battery.

[0004] For electronic watches, please note the following: Do not press the buttons too forcefully to avoid malfunction; the LCD panel should be replaced after five to seven years; remove the battery promptly when it is dead to prevent electrolyte leakage and corrosion of the movement. If you find that the light is not working, the buttons are malfunctioning, or the timekeeping suddenly has a large error, you should have it repaired immediately, as it may be due to poor contact or detachment of component solder joints. Electronic watches, especially digital electronic watches, generally have poor water resistance. Even if some are marked "waterproof" in the instruction manual or on the back cover, you should still try to avoid contact with water. The structure of electronic watches is different from that of mechanical watches; they are all electronic circuits and components. If water gets into them, it will be "catastrophic," rendering the entire watch unusable. In particular, the LCD panel and integrated circuits are not only susceptible to water damage, but also to moisture damage, which can cause malfunctions over time. Therefore, it is best to remove the watch when washing your face or doing laundry. Prevent rainwater from splashing on the watch. If water gets into your electronic watch, or if moisture accumulates inside the watch crystal, it should be taken to a watch repair shop immediately for dewatering and moisture removal. Wearing a watch requires a watch strap, which is the general term for the part of the watch that effectively secures the wrist. Watch straps come in a variety of materials, with cowhide being the most common, and alligator leather being the most precious. Alligator leather watch straps are even known as the "platinum" of leather watch straps. After production, watch straps require random sampling and testing to determine their tensile strength. However, existing watch strap tensile strength testing devices are not convenient to install during watch strap installation, thus affecting testing efficiency. Utility Model Content
