Abstract: An LED rear warning lamp includes a deflector plate assembled at a rear side of an automobile and formed with an accommodating chamber in the interior. A lamp set in the accommodating chamber of the deflector plate is composed of a base, a transparent inner cap, an LED circuit board, a cover plate, a shade and a transparent lamp casing. The LED circuit board is closely attached to the cover plate and then reversely fixed with the transparent inner cap that has its inner lower side protuberantly provided with irregularly refractive patterns. Thus, when reverse light of LEDs is projected upon the refractive patterns of the transparent inner cap, the refractive patterns will refract the light to the transparent lamp casing to send out even and soft light for warning.

Abstract: A roller apparatus for generator, pump and the like is disclosed, where the generator, pump or the like is lodged in a frame, and the roller apparatus is set up at the bottom of the frame, comprising: a plurality of rollers, for rolling along the ground; and a plurality of link units, for linking each roller to the frame, where each link unit is provided with: a brace, obliquely set up at each bottom corner of the frame with a screw hole; a wheel carrier, having its bottom portion join fixedly to the roller and its top portion fixed by a fastener with a shaft portion, for oscillating up and down, and having a screw hole at its middle; and a fixing article, joining the wheel carrier.

Abstract: A blade assembly for a horizontal-axis wind turbine includes a hub, and a plurality of detachable blade units each mounted on a periphery of the hub and each including a plurality of blades detachably connected with each other by a plurality of connecting devices. Thus, the blade assembly comprises a hub and a plurality of detachable blade units so that all parts of the blade assembly are detachable to reduce the whole volume of the blade assembly before assembly, thereby facilitating packaging, storage and transportation of the blade assembly.

Abstract: A liquid crystal display comprises a frame, a backlight module, a panel module and an ultraviolet glue. The backlight module is installed in the frame. The panel module is located on the backlight module. The ultraviolet glue is installed between the panel module and the frame for fixing the panel module and the frame. Steps of a fixing method for a liquid crystal display comprise: placing a backlight module in a frame; placing a panel module on the backlight module; placing an ultraviolet glue between the panel module and the frame.

Abstract: A pump includes a main body, a removable cover, an urging plate, an elastic member, and a control knob. Thus, the removable cover is locked on and unlocked from the main body easily, rapidly and conveniently by rotation of the control knob, thereby facilitating the operator mounting the removable cover. In addition, the locking portion of each of the two end portions of the urging plate is closely locked in the locking hook of a respective one of the catch members of the main body by rotation of the control knob, so that the removable cover is locked on the main body rigidly and stably.

Abstract: An air cooled type generator includes a housing, an engine, a cooling fan mounted in the engine, a generator body having a first side juxtaposed to the engine, and a cooling fan rotatably mounted on an opened second side of the generator body and including a plurality of blades each having an inner side formed with a first wing and an outer side formed with a second wing. Thus, the first wing and the second wing of each of the blades co-operate to carry the hot air away from the generator body rapidly, thereby enhancing the heat dissipation effect of the cooling fan. In addition, the generator only needs to provide two cooling fans to achieve the heat dissipation effect, so that the generator has a simplified construction and a smaller volume and is assembled easily and conveniently.

Abstract: A generator includes a housing, an engine, a first main impeller rotatably mounted in the engine, a first secondary impeller rotatably mounted in the housing and located outside of the engine, a generating body, a second main impeller rotatably mounted in the generating body, and a second secondary impeller rotatably mounted in the housing and located outside of the generating body. Thus, the first secondary impeller and the second secondary impeller can dissipate the heat produced from the engine and the generating body, thereby enhancing the heat dissipation effect of the generator, and thereby increasing the lifetime of the generator.

Abstract: A pump includes a main body, a water outlet connector rotatably mounted on the main body, and a positioning bar detachably mounted on the main body and rested on the water outlet connector for locking the water outlet connector on the main body. Thus, the included angle between the water outlet of the water outlet connector and the main body can be adjusted easily and conveniently without needing aid of an additional tool, thereby facilitating the user adjusting the included angle between the water outlet connector and the main body.
