The shift head is fixed to the transverse shift lever, and a gear selecting lever and a dual-H valve are arranged on the positions, corresponding to the matching position of the shift head, of the control shell respectively. The gear selecting hand feel control block is fixed to the transverse shift lever, and the control shell is provided with the hand feel pin matched with the surface of the gear selecting hand feel control block. The hand feel pin is connected to the control shell through a spring. The contact face of the gear selecting hand feel control block and the hand feel pin is provided with working surfaces corresponding to gear selecting operation in sequence, the working surfaces corresponding to selecting from low gears to a rear gear are inclined planes extending outwards in the axial direction, and the working surfaces corresponding to selecting from high gears or a neutral gear to high gears are provided with outward protrusions. When the hand feel pin makes contact with the inclined planes or the protrusions, the spring is compressed.

The invention discloses a cable sealing connector used for a ship in a deep water environment. The cable sealing connector comprises a sleeve, a pressing nut, a pressing ring, a sealing ring and a separating disc. The first end of the sleeve is provided with a flange used for connection, the second end of the sleeve is in threaded connection with the pressing nut, the middle section of the sleeve is a small-diameter through hole, the section, close to the first end, of the sleeve is a first large-diameter through hole, the section, close the second end, of the sleeve is a second large-diameter through hole, the pressing ring and the sealing ring are arranged in the second large-diameter through hole and are sequentially located on the inner side of the pressing nut, the separating disc is arranged in the small-diameter through hole, the diameter of the pressing nut, the diameter of the pressing ring, the diameter of the sealing ring and the diameter of the small-diameter through hole are the same and are slightly larger than the outside diameter of a cable used for the ship, and the separating disc is provided with a plurality of through holes which wires penetrate through. According to the cable sealing connector, the structure integrating the sleeve, the pressing nut, the pressing ring and the sealing ring is adopted, a connector of the cable for the ship is sealed so that the connector can bear large enough water pressure, and on the condition that the water pressure is not higher than 20 MPa, it is guaranteed that cables used for the ship and mutually connected are stably sealed and connected.

The invention belongs to the technical field of electrical plugs, and specifically relates to a wiring-type sealing plug for a pump, which includes a plug body and a wire nut; the end of the wire nut far away from the plug body is fixedly connected to a connecting pipe; the inner wall of the connecting pipe is fixedly connected to There is a sealing layer; the inner wall of the wire nut is provided with a No. 1 groove; the No. 1 groove is close to the connecting pipe; the inside of the No. 1 groove is provided with a No. 1 slider, a clamping block and a spring; The end away from the plug body is fixedly connected with a connecting pipe, and then cooperates with the clamping block on the inner wall of the wire nut, so that the wire nut can fix the wires of different diameters and ensure the sealing effect of the wires, and then realize different diameters. All wires can achieve stable and sealed connection at the terminal nut, which improves the application range of the pump wiring type sealing plug, and can ensure the connection stability of the pump wiring type sealing plug when using wires of different diameters.

An aluminum alloy window frame sealing connection structure solves the problem of rainwater leakage caused by insufficient filling of the gap between the aluminum alloy window frame and the opening wall. It includes an aluminum alloy window frame and a stone panel fixed on the wall of the hole. The frame and the hole wall are sealed and connected with a waterproof rubber plate. After one end of the waterproof rubber plate is connected and fixed with the aluminum alloy window frame frame by stainless steel screws, it is sealed with the stone panel by a sealing material. The other end of the waterproof rubber plate is connected to the hole. The wall is connected and fixed by nailing, the gap between the bottom of the waterproof rubber plate and the wall of the hole is sealed with sealant, and the gap between the waterproof rubber plate and the steel sub-frame is filled with thermal insulation material. Its structural design is reasonable to ensure that the gap is filled full and dense without cracks, and the sealing connection is reliable, which can effectively prevent rainwater leakage and improve the airtightness and thermal insulation performance of aluminum alloy windows.

The invention discloses a steel-plastic composite pipe connector and a method thereof. The steel-plastic composite pipe connector comprises a connecting head body and a connecting pressing set. The two ends of the connecting head body are provided with conical connectors, wherein a steel-plastic composite pipe head can be sleeved with the conical connectors in an inserted manner. First connecting flanges are arranged at the positions, on the inner sides of the conical connectors, on the connecting head body. Multiple L-shaped grooves are formed in the included angle faces of the outer side faces of the first connecting flanges and the connecting head body in a surrounding manner. L-shaped tensioning blocks are arranged in the L-shaped grooves. The connecting pressing set comprises second connecting flanges and pressing sleeves. The pressing sleeves are also in a cone shape, and the second connecting flanges are arranged at the large-head ends of the pressing sleeves. The connecting pressing set can be used for clamping and sealing the steel-plastic composite pipe head by being arranged on the conical connectors in a sleeving manner, and the second connecting flanges and the first connecting flanges are matched and are firmly connected through bolts. The problems that a relatively thick steel-plastic composite pipe connector is not firm in connection, and a pipeline and the connector are likely to be disengaged or water leakage and gas leakage are likely to happen are solved.

The invention discloses a multilayer inspection well and a manufacturing method thereof. The inspection well comprises multiple layers of well shafts, multiple layers of well bases, and a well lid, wherein the well base in each layer comprises a cylindrical base part, well shaft connectors which extend from the upper and lower ends of the base part, and at least one transversely formed pipeline connector; at least one ends of the well shafts are in fusion welding with the well shaft connectors in a thermoplastic manner; and the upper end of the well shaft in the topmost layer is connected with the well lid. When the multilayer inspection well is utilized, pipelines which are embedded in different underground vertical positions and have various different functions can be monitored at the same time in one inspection well; the well shafts and the well bases are in sealed connection, so that the inspection well is more stable; and when the well shafts and the well bases are connected and when the ground subsides due to overload or underground tunnels subside due to various reasons, the well shafts of the inspection well can have certain elastic deformation due to the fact that the well shafts have certain elasticity, so that connection of the pipeline connectors of the inspection well and the original pipelines remains stable, sealing performance is good, and the inspection well is not liable to damage.
