The invention relates to transmission mechanisms of a lateral-movement inwards-inclining window. Each transmission mechanism comprises a fixed seat which is fixedly installed on a window sash, a shortconnecting rod which makes the window sash inclines inwards, a long connecting rod which makes the window sash open and laterally moves and a first locking device which locks or unlocks the short connecting rod, wherein one end of the short connecting rod is hinged to the fixed seat, and the other end of the short connecting rod is hinged to one end of the long connecting rod; the other end of the long connecting rod is hinged to a first sliding block; a sliding rail is fixedly installed on a frame; and the first sliding block is installed on the sliding rail and slides along the sliding rail. A first limiting device is disposed on one of the transmission mechanisms and comprises a limiting connecting rod, a sliding rod and a second locking device, wherein one end of the limiting connecting rod is hinged to the middle of the long connecting rod; the sliding rod is fixedly installed on the short connecting rod; the second locking device locks the limiting connecting rod; a first sliding groove which is matched with the sliding rod is formed in the other end of the limiting connecting rod; and the sliding rod is disposed in the first sliding groove and slides along the first slidinggroove. By means of the transmission mechanisms of the lateral-movement inwards-inclining window, the window sash is limited when the window sash inclines inwards, so that the window sash is prevented from being automatically closed, and the anti-shock function is achieved.

The invention relates to a high-strength PC optical cable connect, which comprises the following components, by weight part, 50-75 parts of modified polycarbonate, 45-60 parts of polyvinyl chloride, 30-50 parts of modified carbon fibers, 1-3 parts of a lubricant, 1-2 parts of a nucleating agent, 5-7 parts of benzoyl peroxide, 4-6 parts of pentaerythrityl tetrastearate, 20-35 parts of calcium carbonate powder, 1-3 parts of an antioxidant, 6-10 parts of an ultraviolet screening agent, 3-7 parts of modified graphene, 1-3 parts of nanometer silicon carbide and 5-10 parts of nanometer chromium carbide. The high-strength PC optical cable connect is flame-retardant, waterproof and shockproof, is high in strength, and is good in toughness, ultraviolet resistance, aging resistance and weathering resistance.

The invention discloses a fan base sucker. The fan base sucker structurally comprises a sucker and a sucker base; four suckers are mounted uniformly on a lower bottom of the base; aspirating holes of the suckers are formed in the base to facilitate air exhaust; each sucker is made of a flexible glue material and has a certain buffering effect, and therefore, vibration between the base and the ground is reduced.

The invention discloses a waterproof mobile power supply device, which includes a hard shell and a soft rubber sleeve. A battery, a circuit board and an interface are installed in the hard shell. The hard shell includes a main shell and an end cover. The upper end of the main shell is open. , the end cover is packaged at the opening, the soft rubber sleeve covers the outside of the main shell, and the upper edge of the soft rubber sleeve is pressed by the edge of the end cover to cover the periphery of the opening. This design integrates the traditional soft rubber sleeve and sealing ring, which not only eliminates the instability and easy loosening of the soft rubber sleeve during use, but also saves the purchase cost, management cost and installation cost of the sealing ring. , At the same time, the mobile power supply is also waterproof. And the soft rubber sleeve has two sealing parts, and the two sealing parts are pressed on the main shell by the end cover at the same time, which can further enhance the waterproof sealing and the installation stability of the soft rubber sleeve. The soft rubber cover is also provided with a soft rubber cover that can be opened and closed, making it difficult for external moisture and dust to directly enter the mobile power supply, prolonging the service life of the mobile power supply.
