Abstract: A link connecting structure includes two outer link plates and two inner link plates. An inner side of each outer link plate is formed with a concave portion between two first coupling portions at two ends thereof. A connecting surface is connected between each first coupling portion and the concave portion. The connecting surface is gradually tapered inward from each first coupling portion toward the concave portion. An outer side of each inner link plate is provided with a pair of bent portions each extending from an outermost edge of each second coupling portion toward the connecting surface. A gap is defined between each bent portion and the connecting surface. The gap is less than the minimum thickness of a narrow tooth of a chainring, thereby preventing the tooth from being jammed in the gap.

Abstract: A heavy-duty bicycle chain structure includes two oppositely disposed inner link plates, a link roller, a sleeve, two oppositely disposed outer link plates, and a link pin. The link roller lies between the inner link plates, which are each at least 1.5 mm thick. The sleeve is pivotally connected to the inner link plates and the link roller and has a first pin hole 4.05±0.1 mm in diameter. Each outer link plate has two ends each formed with a second pin hole 4.05±0.1 mm in diameter. The link pin has a diameter of 4.0±0.2 mm, is placed in the first pin hole and the corresponding pair of second pin holes, and is thus pivotally connected to the sleeve and the outer link plates. The bicycle chain structure features a large contact area between the link pin and the sleeve and hence high tensile strength.

Abstract: A display system includes a display device and an HDMI dongle electrically connected to the display device. The display device includes a first transmission interface, a first control module, and a power supply module. The HDMI dongle includes a second transmission interface and a second control module. The first and the second transmission interfaces include transmission pins corresponding to each other. The first control module detects voltage of one pin to obtain matching state between the display device and the HDMI dongle and outputs an enabling signal. When the HDMI dongle matches the display device, the enabling signal controls the power supply module to transmit the power supply signal to the second control module through the first and the second transmission interfaces for charging the second control module. When the HDMI dongle does not match the display device, the power supply module is not transmitted to the second control module.
