Abstract
The present invention relates to screw, and is one kind of waterproof screw capable of being penetrated by wire. The screw may be used for connection and fastening of special underwater computer. The waterproof screw includes tubular screw, screw nut and waterproof hose with flange in the end. The screw nut has end plate perpendicular to the side wall and connected to the side wall integrally and inner thread in the side wall, and the end plate has port matching with the outer diameter of the waterproof hose. The tubular screw has axial through hole and outer thread for connection with the screw nut. The waterproof screw may be used in underwater electronic equipment.
Description
Technical field
The present invention relates to a kind of screw, relate in particular to and a kind ofly can pass lead, screw that again can waterproof, this screw can be used for supplying water down, and the shell of the extraordinary computer that uses connects and fastening.
Background technology
Existing screw mainly has been to connect or fastening effect, and is behind the screw-driving that screw hole is airtight, can not walk any object, and water proofing property is not strong yet.
Along with science and technology development, equipment or device that some use at the ground water-less environment also need to use under water sometimes, and this just needs reliable waterproof measure.Sometimes also need keep excellent waterproofness drawing under the situation of lead.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of Water-proof screw is provided, and it not only can pass lead, can also waterproof, and the waterproof of the electronic equipment that can be used for using under water and cabling.
Technical problem of the present invention solves by following technical solution: a kind of Water-proof screw, it is characterized in that, and comprise screw pipe, nut and anti-water tube hose; The end of described anti-water tube hose is provided with flange shape flange; The tail end of described nut be provided with vertical with the nut sidewall and with the end plate that sidewall is connected as a single entity, be provided with the port that matches with the external diameter of described anti-water tube hose at the middle part of described end plate; The sidewall of described nut is provided with internal thread; Described screw pipe is the tubular body that axis is provided with through hole, and its lateral wall is provided with and the corresponding external screw thread of the internal thread of described nut.
Aforesaid Water-proof screw of the present invention, its anti-water tube hose can be used for passing lead, and the length of flexible pipe tail end can prolong arbitrarily according to actual needs; The flange shape flange of flexible pipe front end is posted by nut end plate inboard in use, and compresses by the screw pipe, makes water to infiltrate through the nut port outside hose wall.The screw pipe also is used to allow lead pass, and is used for screw integral body is connected in the housing of certain device except being used for hose end compressed.Below in conjunction with drawings and Examples the present invention is described in further detail.
Description of drawings
Fig. 1 is the STRUCTURE DECOMPOSITION figure of an exemplary embodiments of Water-proof screw of the present invention;
Fig. 2 is a Water-proof screw assembled state axial section of the present invention shown in Figure 1.
Embodiment
Water-proof screw of the present invention as depicted in figs. 1 and 2 comprises screw pipe 1, nut 2 and anti-water tube hose 3; The end of anti-water tube hose 3 is provided with flange shape flange 4; The tail end of nut 2 be provided with vertical with the nut sidewall and with the end plate 5 that sidewall is connected as a single entity, be provided with the port 6 that matches with the external diameter of preventing water tube hose 3 at the middle part of end plate 5; The sidewall of nut 2 is provided with internal thread 7; Screw pipe 1 is provided with the tubular body of through hole for axis, and its lateral wall is provided with the internal thread 7 corresponding external screw threads 8 with nut 2.Anti-water tube hose 3 can be used for passing lead, and the length of flexible pipe 3 tail ends can prolong arbitrarily according to actual needs; The flange shape flange 4 of flexible pipe 3 front ends is posted by nut end plate 5 inboards in use, and compresses by screw pipe 1, makes water to infiltrate through nut port 6 outside flexible pipe 3 walls.Screw pipe 1 also is used to allow lead pass, and is used for screw integral body is connected in the housing of certain device except being used for flexible pipe 3 ends are compressed.
For further improving water proofing property, present embodiment has also designed following structure: be provided with the polygonal flange 9 vertical with its sidewall in the front end end of screw pipe 1, be provided with internal thread 10 on the madial wall of screw pipe 1.Simultaneously, also be provided with a screw pipe 11, the lateral wall of screw pipe 11 is provided with the internal thread 10 corresponding external screw threads 12 with screw pipe 1; Preceding extreme direction at screw pipe 11 is provided with the polygonal flange 13 vertical with its sidewall.When installing and using, flange 9 is positioned at the outside of a housing, and flange 13 is positioned at the inboard of this housing, when tool using is tightened screw pipe 1 and screw pipe 11, flange 9 and flange 13 will clamp housing, thus with the screw overall fixed on housing, anti-simultaneously this water is from infiltrating with the junction of housing.
Also can be provided with and flange 13 conduits 14 vertical and that be communicated with the pore of screw pipe 11 in the front side of flange 13.
Anti-water tube hose 3 in the Water-proof screw of the present invention can adopt plastic tube, and polygonal flange 9 and polygonal flange 13 can be regular hexagon.
Water-proof screw of the present invention can pass lead, again can waterproof, and the waterproof of the electronic equipment that can be used for using under water and cabling, the shell of the extraordinary computer that uses of especially can be used for supplying water down connects and is fastening.
