The center of the plastic connector body is provided with a through hole for a guide line to penetrate through, the plastic connector body is provided with a protruded screwing portion, an inner end portion and an outer end portion, the periphery of the inner end portion and the periphery of the outer end portion are provided with outer threads, a seal ring is sleeved on the inner end portion, the annular end face of the outer end portion and the outer end portion are integrally provided with a sawtooth structure consisting of a plurality of sawteeth, the root portions of the sawteeth are larger than the tip portions, the portions from the root portions to the tip portions are streamline-shaped, and the sawtooth structure is provided with a guide line sealing part in a surrounding mode. The guide line sealing connector further comprises a plastic nut provided with a hollow cavity and capable of being screwed at the outer end portion. By means of technical improvement, the guide line sealing connector fully utilizes the elasticity of structural parts and plastic to achieve the sealing effect, is easy to assemble, high in sealing reliability and low in cost.

The invention relates to a constant-temperature drinking device which comprises an inner cavity, an outer cavity, a function cavity and a covering device. The overall structure is improved, and therefore sealing performance is guaranteed. A heating component and heat conduction liquid are arranged, and therefore drinking water in the drinking device can keep drinking temperature constantly, and even though hot water is poured into the drinking device, the hot water can be cooled to the drinking temperature within a short time; the water can be directly drunk when drunk at any time by setting the drinking temperature; and the drunk water is not unboiled water and boiled water, and the aims of constant-temperature drinking and drinking at any time are really achieved.

The invention provides a sealed connection structure and a connector using the sealed connection structure, wherein the sealed connection structure includes a fixed base and a flexible sealing sleeve, the fixed base is provided with a sealing connection surface for connecting the flexible sealing sleeve, and the flexible sealing sleeve passes through The connecting piece and the annular pressure plate are connected on the sealing connection surface, and the outer edge and / or inner edge of the annular pressure plate are provided with a limiting structure extending toward the sealing connection surface for limiting the amount of compression deformation of the flexible sealing sleeve. The sealing connection structure of the present invention connects the flexible sealing sleeve to the sealing connection surface of the fixed base through the connecting piece and the annular pressure plate. Compared with the connection with the mounting plate through the self-deformation of the sealing rubber sleeve, the connection strength is high, and the connection will not cause failure. At the same time, the limit structure can limit the amount of compression deformation of the flexible sealing sleeve, preventing the sealing rubber sleeve from being over-compressed beyond the deformation limit and losing its elasticity, which cannot achieve a sealing effect.

The invention discloses an assembling device with a sealing function. The assembling device comprises a first separating body, a second separating body and a gasket, wherein the first separating body is provided with a first surface, the second separating body is provided with a second surface, the gasket is provided with a convex rib, the convex rib is in contact with the first surface and the second surface, at least one side of the convex rib is provided with a branch groove in a protruding way, at least one end of an elastic body which is fixedly arranged on the convex rib is embedded in the branch groove, and the elastic body is simultaneously in contact with the first separating body and the second separating body. Compared with the design of a traditional gasket, due to the additional arrangement of a glue groove and the elastic body, the sealing problem in a height difference can be completely solved, complete sealing can be achieved, and the sealing reliability can be increased; the gasket has a better adaptability on the height difference, the processing accuracy of a flange surface can be reduced, thus the processing efficiency is increased, and the cost is saved.

The invention discloses a separable sealing structure of a dragline anchor. The separable sealing structure comprises a sealing structure at an anchor head end and a sealing structure in an anchor head, wherein the sealing structure at the anchor head end comprises an anchor plate, a base plate and an O-shaped sealing ring I arranged on the base plate; the sealing structure in the anchor head comprises a sealing cylinder, a pressing plate, an inner sealing plate, a pressure-bearing cushion cover, an O-shaped sealing ring II, a sealing cushion cover and an outer sealing plate; the pressing plate, the inner sealing plate, the pressure-bearing cushion cover, the O-shaped sealing ring II, the sealing cushion cover and the outer sealing plate are sequentially arranged in the sealing cylinder; a connecting piece comprises a pressing rod, a pressing screw and a tightening screw; the pressing rod penetrates through a through hole II in the anchor plate and a straight-through hole II of the pressing plate, directly reaches a blind hole I of the inner sealing plate and clamps the pressing plate around a shoulder; the pressing screw is tightly attached to the pressing rod for ejecting the pressing rod; the pressing rod ejects the pressing plate; one end of the pressure-bearing cushion cover is tightly attached to the pressing plate and is ejected; the other end of the pressure-bearing cushion cover is tightly attached to the sealing cushion cover and extrudes the sealing cushion cover. The separable sealing structure of the dragline anchor is reliable in sealing; the disassembly and the assembly for multiple times can be realized; the maintenance and the operation are easily realized; meanwhile, steel stranded wires can be singly changed.

The invention relates to the technical field of sealing devices, in particular to a universal sealing device for a distribution box and a cabinet type wire inlet and outlet. The universal sealing device comprises an electric meter box and a sleeve arranged outside the electric meter box, wherein a sleeve opening is formed in the side portion of the electric meter box. One end of the sleeve is connected to the outside, and the other end is connected to the sleeve opening; and a sealing sleeve is arranged at the opening of the sleeve. The length of required soft plastic can be adjusted accordingto the sizes of the distribution box and the cabinet type wire inlet, and an interface is manually sealed after the distribution box and the cabinet type wire inlet are sleeved with the circuit sleeve, so the meter box interface achieves a sealing effect.
