The invention discloses an elastic suction nozzle cover and a water cup, and the elastic suction nozzle cover comprises a drinking component, a turning cover, a cup opening sealing panel, a turning cover assembling seat, a suction nozzle channel piece and a supporting bracket. The suction assembly comprises a suction nozzle and a suction pipe which are communicated, a first protrusion is arranged on the outer side of the suction nozzle, and the suction pipe is sleeved with a limiting piece which is sleeved with a spring; the suction nozzle channel piece is provided with an open inner cavity for containing the drink suction assembly. The cup opening sealing panel is provided with a first opening used for exposing the suction nozzle, and a rotatable shifting rod is arranged on the inner side of a second opening. The flip cover can rotate relative to the cup opening sealing panel, and extrudes the driving lever through the second opening during rotation, so that the driving lever presses the spring to contract, and the suction nozzle contracts along with the driving lever to form storage. The cup opening sealing panel, the flip assembling base and the supporting bracket integrally form a space for containing the suction nozzle channel piece, and the cup body is detachably fixed. According to the technical scheme, automatic stretching and retracting of the suction nozzle are achieved through mechanical linkage, and the problems that a traditional suction nozzle is prone to pollution, poor in sealing performance, poor in heat preservation effect and inconvenient to operate are solved.

An air pump with an integrated air inlet and outlet valve comprises an air cylinder (1), a piston (2) arranged in the air cylinder (1), an air outlet pipeline (3), an air inlet valve (4) and an air outlet valve (5). The air inlet valve (4) and the air outlet valve (5) are made of elastic materials and are integrally arranged at the bottom of the air cylinder (1). The air outlet valve (5) is provided with an upper opening (51) which is large in width and is opened in a natural state and a lower opening (52) which is small in width and is closed in a natural state, the upper opening (51) is opposite to an inner cavity of the air cylinder (1), and the lower opening (52) is opposite to the air outlet pipeline (3); and an air inlet hole (11) corresponding to the air inlet valve (4) in position is formed in the bottom of the air cylinder (1). The air pump can effectively reduce the temperature in the pump during air inflation and the risk of damage in the using process, and is simpler in structure, easy to assemble, small in size and convenient to carry.

This utility model relates to the field of rehabilitation exoskeleton technology, specifically a waterproof sealing structure for a rehabilitation exoskeleton. It includes a first leg and a sealing device. A second leg is rotatably mounted on the upper surface of the first leg. The sealing device is disposed on the surface of the second leg and includes a fixing plate fixedly connected to the second leg. A rubber sleeve is fixedly connected to the lower surface of the fixing plate, and the rubber sleeve is fitted onto the pivot joint of the second and first legs. This utility model, by setting up a sealing device, utilizes an iron plate and a magnetic plate for adsorption and fixation, and further stabilizes it with a threaded rod, ensuring that the sealing sleeve tightly fits onto the pivot joint of the first and second legs. This structure forms a reliable sealing space, greatly reducing the entry of moisture into the joint area, preventing damage to electronic components due to short circuits caused by moisture, reducing rust and corrosion of mechanical parts due to moisture erosion, thereby extending the service life of the exoskeleton joint and ensuring its stable operation.

The utility model relates to the technical field of conductor spacer, and disclose a kind of double split conductor spacer, including spacer body and wire clamp component, wire clamp component is equipped with two groups and is arranged at the both ends of spacer body;Spacer body includes two front and rear oppositely arranged isosceles trapezoidal cross plate and is symmetrically arranged and connects two isosceles trapezoidal cross plate's connecting rod, two isosceles trapezoidal cross plate is detachably connected by connecting rod, forms an isosceles trapezoidal frame structure;Wire clamp component and spacer body are detachably connected by bolt A.Isosceles trapezoidal frame structure has significant advantage, can better disperse and bear stress under wind force, conductor dancing and other external force, reduce structural deformation, guarantee spacer overall stable and reliable, detachable connection mode makes installation and maintenance more convenient, can transport component to site assembly respectively, also facilitate replacement component and overhaul.
