The utility model discloses an automatic lubricating device for motorcycle chain, including oil storage tank, top adjusting unit, vacuum valve, pipeline and oil outlet device, the oil storage tank is equipped with the feeding opening, the top adjusting unit sets up at the top of oil storage tank, and it contains rotatable adjusting part, the pipeline flows from the oil storage tank into the oil outlet device, the bottom of oil storage tank is equipped with the inclined flow guide surface, can guide lubricating oil smooth flow to the oil outlet channel, the oil storage tank still includes user operation device, vacuum device, distributor oil pipe and valve device, the automatic lubricating device for motorcycle chain, the inclined flow guide surface of oil tank bottom can guide lubricating oil smooth flow to the oil outlet channel, and cooperate rotatable adjusting part of top adjusting unit and the scale mark on its surface, can accurate control oil outlet channel cross -section area, and then realize accurate regulation to the oil discharge capacity, ensure that motorcycle chain obtains sustained, appropriate lubrication, and the service life of chain is improved and the working performance.

The utility model relates to a pressing and unfolding device of a satellite antenna, which does not need an independent locking and releasing mechanism. Comprising the steps that a flexible antenna is arranged on the side face, facing a solar panel, of a satellite body; when the solar panel is in a locked state, the flexible antenna is bent and arranged between the satellite body and the solar panel and is in a compressed state; when the solar panel is unfolded, the flexible antenna is unfolded along with the solar panel, the compressed state is converted into the natural state, the flexible antenna is smoothly unfolded, an additional locking and releasing mechanism is not needed in the whole process, the manufacturing and maintenance cost is reduced, and the risk of task failure caused by complex mechanism faults is reduced.

The invention belongs to the technical field of laser welding, and particularly discloses a laser welding tool for ball valve production, the laser welding tool for ball valve production comprises a box body, a guide rail is arranged in the box body, a laser welding device is arranged on the guide rail, and the laser welding device comprises a laser welding head arranged on one side of the guide rail and used for welding. The angle of the second nozzle is adjusted through the driving structure, when a complex curved surface welding seam is welded, the fitting degree of the rear dragging air curtain can be guaranteed, and the situation that when different areas of the curved surface welding seam are welded, airflow dead angles occur, the welding seam is still in contact with air, and oxidation discoloration is caused is prevented; the bottom of the first nozzle can be protected and shielded, the probability that air holes in the bottom of the first nozzle are blocked by metal splashes generated during ball valve welding is reduced, the first nozzle is prevented from being collided and affecting use, and then the service life of the first nozzle is prolonged, and the working effect of the first nozzle is improved.
