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 flat panel display device includes a rear housing defining a containing space, a support member disposed in the containing space and secured to the rear housing, a display panel secured to a front face of the support member, a front frame, and a motherboard. The front frame covers a peripheral portion of a front face of the display panel, is connected to the rear housing, and includes light guides extending into corresponding holes in the front frame. The motherboard includes a board body secured to a rear face of the support member, a plurality of press buttons disposed on the board body and extending respectively holes in the rear housing, a plurality of light-emitting diodes disposed at the board body, and a wireless signal receiver disposed on the board body. The light-emitting diodes and the wireless signal receiver correspond to the rear ends of the light guides.
Abstract:
A half pitch chain structure for a show bicycle includes chain plates, sleeves, rollers, and pins. Each chain plate comprises an outer link portion at one end and an inner link portion at the opposite end. The inner link portion of one chain plate is connected with the outer link portion of another adjacent chain plate to form a slot therein. The slot has a wide section and a narrow section. The top end of each adjacent chain plate is at the same height level without any differential level.
Abstract:
A forming method for applying a continuous punching to a chain roller includes a raw block having a first surface and a second surface. The raw block would be sequentially punched and formed throughout the first to sixth punching or throughout the first to seventh punching. During the fourth punching, a first blanking would be executed. Alternatively, before executing the sixth or the seventh punching, a second blanking would be implemented.
Abstract:
A chain plate structure includes a first outer link plate and a second outer link plate, and each of which includes a first/second through hole, a first/second connection hole, a first/second trough and a first/second engaging trough at two sides of the first/second connection hole. A first/second rib extends from an inner periphery of the first/second engaging trough and at least one first/second protrusion extends from the first/second rib. When the first and second outer link plates are connected to each other, the gap between two adjacent inner link plates of a chain is less than 2.3 mm.
Abstract:
A high-strength chain plate structure comprises an inner plate body and an outer plate body. The inner plate body has a first waist portion provided with a first receiving portion and a first outer side portion. The first outer side portion has a first slope. The first slope and the first waist portion form a continuous two-step structure. The outer plate body has a second waist portion provided with a second receiving portion and a second outer side portion. The second outer side portion has a second slope. The second slope and the second waist portion form a continuous two-step structure. The tensile strength, impact resistance and torsion resistance of the chain can be improved.
Abstract:
A chain plate structure includes a link plate body and a sleeve. The link plate body has an acting surface being provided with a first approach edge, two combining portions, and a limiting block located adjacent to the first approach edge. The limiting block has an altitude higher than an altitude of the acting surface. The sleeve is mounted on the link plate body and has a through hole whose maximum diameter is greater than a maximum diameter of a raised ring peripherally formed on the corresponding one of the combining portions. Therefore, when two of the link plate bodies are combined together, a first space is formed between the acting surfaces of the two aligned link plate bodies. The limiting block serves to limit the first space, while the sleeve is allowed to move on one of the combining portions so as to provide a second space.
Abstract:
A cap assembly includes a first part for mounting to a bottle and a second part coupled to the first part, and a sucking member pivotally disposed to a top of the first part. The top of the first part has two stands, a support located between the two stands and a stop extending therefrom, wherein the support has a passage defined therethrough and extending through the top. The sucking member has a sphere member rotatably supported between the two stands and is rested on a first annular flange extending from a top of the support. The second part has two clamping members extending from a bottom thereof so that when the second part is mounted to the first part, the sucking member is clamped by the clamping members and pivoted and laid on the stop.
Abstract:
Disclosed is an audio transmission device for mounting in a monitor of a computer system and including a pair of symmetric frameworks mounted behind a front frame of the monitor at two lower or upper corners thereof so that a distance left between the pair of frameworks is about a width of a system board disposed inside the monitor. The framework each further includes a fixing arm formed at an inner side with a longitudinal groove which has a width slightly larger than a thickness of the system board to clamp the same between the pair of frameworks, a connecting arm extended from one side of the fixing arm, a resonant cabinet connected to the fixing arm via the connecting arm, and shock-absorbing arms extended from two side walls of the resonant cabinet for locking to the front frame of the monitor. The resonant cabinet is partitioned inside it to form a high-tone and a low-tone guide paths. The high-tone guide path is formed at a base portion with supporting grooves for a speaker to mount thereon. The fixing arm each is provided at an extended end with locating device to engage with a fixed point provided behind the front frame of the monitor and thereby fixing the framework to the front frame.
Abstract:
A connection unit of a chain includes two outer link plates each having a first hole and a second hole. The second hole has a first recess and a second recess which communicates with the first recess. The first recess has a diameter larger than that of the second recess. The second recess includes an inner surface and a stepped engaging surface which is perpendicular to the inner surface. A stop surface is perpendicularly connected to the engaging surface. At least one first protrusion extends from the inner surface. A pin is securely fixed in the first hole and includes an engaging portion. A neck is located beside the engaging portion and has a diameter smaller than that of the engaging portion.
