One locking part 3, it is one to be provided with the lid of internal thread, and lid is provided with open-work 31, and described locking part 3 screw fixed are in described pedestal 1 other end, and the lid medial surface is pressed on described seal 2 upper ends;
As Fig. 2, shown in Figure 3, in this structure, the diameter of described half slot 21 is definite according to the external diameter of described cable 8 or pipeline 7, can be identical with the diameter of described cable 8 or pipeline 7 (or bigger by 0.5～1mm) than the external diameter of cable 8 or pipeline 7; The size of the pipe joint 71 that plug 81 that the radial dimension of minimum-value aperture 13 connects more than or equal to described cable in the open-work 31 on the described lid and the pedestal 1 or pipeline connect (, plug 81 or pipe joint 71 are passed) as long as the radial dimension of minimum-value aperture 13 is not less than the minimum compact mechanism of described plug 81 or pipe joint 71 in common described open-work 31 and the pedestal; In the present embodiment, the radial dimension of minimum-value aperture 13 is Φ 42mm in open-work 31 and the pedestal, can be by plug or the pipe joint of maximum outside diameter≤42mm.
The use of locomotive indoor and outdoor cable of the present utility model or pipeline hermetically-sealed construction through walls is: as Fig. 2, shown in Figure 3, pedestal 1 is welded on the through hole 91 of locomotive wallboard 9, when crossing line or crossing the pipe assembling, locking part 3 is passed plug 81 in elder generation or pipe joint 71 is enclosed within on cable 8 or the pipeline 7, the hole 13 that plug 81 or pipe joint 71 are passed pedestal is connected with in-vehicle device that (cable 8 other ends are connected with locomotive outdoor electrical equipment 82, as shown in Figure 4) again.At plug 81 or pipe joint 71 with after equipment is connected, 2 pairs of two rubber seals mutual involutory entangle cable 8 or pipeline 7 after, insert in the hole of the other end of pedestal 1, then locking part 3 is pushed down two seals 2 and be screwed on the pedestal 1, apply suitable moment of torsion locking part 3 is tightened.Because the set terminal of seal 2 is provided with the taper seat 22 that matches with pedestal internal tapered hole 12 (in the present embodiment, tapering is 45 degree), the pressure that is produced when tightening locking part 3, make seal 2 radial expansions, clamping cables 8 or pipeline 7, eliminate the gap between seal 2 and cable 8 or the pipeline 7, also eliminated between two rubber seals and the gap between rubber seal 2 and the pedestal 1 simultaneously, reached good reliable sealing effect.
The utility model has overcome that " η " shape pipe in the prior art is through walls crosses that the line mode must vertically be installed, the problem of crossing line of dustproof, uncomfortable crossed belt plug cable; Overcome the problem of crossing linear sealing part complex structure, being not suitable for vertical installation, can not solid and reliablely fixing, be not easy to when crossing line assembly operation of external production; Also solved simultaneously the problem through walls of pipeline.From the above mentioned, locomotive indoor and outdoor cable of the present utility model or pipeline hermetically-sealed construction through walls have reliable sealing and water proof and dust proof effect; And this structure not only can be used for the sealing through walls of cable but also can be used for the sealing through walls of pipeline, was applicable to the sealing through walls of band plug cable and band pipe joint pipeline.
Further, in the present embodiment, described pedestal 1, locking part 3 are made for stainless steel material.
Described locking part 3 is a fine thread with the connecting thread of pedestal 1 other end, tightens the back and produces loosening so that prevent locking part 3.
In the present embodiment, the material of described seal 2 is ethylene propylene diene rubber or is oil resistant rubber.Seal 2 adopts ethylene propylene diene rubber when being used for cable 8 sealings; Seal 2 adopts oil resistant rubber when being used for pipeline 7 sealings.
Described pedestal 1 also can be welded on the locomotive header plate according to the installation site needs.
Structure and the principle of present embodiment and embodiment 1 are basic identical, and its difference is that as Fig. 6, shown in Figure 7 described pedestal 1 one ends pass the through hole 91 of locomotive wallboard 9 and are provided with an extension 14, and the outer wall of this extension 14 is provided with screw thread; One clamp nut 4 is connected in the screw thread of described extension 14; Described this section screw thread also adopts fine thread.
Further, as Fig. 6, shown in Figure 7, described pedestal 1 is provided with a circular orientation portion 15 with locomotive wallboard 9 bearings, so that pedestal 1 can more stably be positioned in the through hole 91 of described locomotive wallboard 9; The side that described circular orientation portion 15 contacts with wallboard 9 is provided with a cannelure 16, and an O-ring seals 5 is set in this cannelure 16, and this O-ring seals 5 is the standard seal part.
During installation, as shown in Figure 7, earlier O-ring seals 5 is placed in the cannelure 16 of pedestal 1, again the extension 14 of pedestal 1 one ends is passed the through hole 91 of locomotive wallboard 9, be connected in the screw thread of described extension 14 by clamp nut 4, pedestal 1 is fixed on the locomotive wallboard 9 solid and reliablely; Crossing line or crossing that to manage assembling process identical with the assembling process of welded and installed mode thereafter.
Other structures, operation principle and the beneficial effect of present embodiment is identical with execution mode 1, does not repeat them here.
Structure and the principle of present embodiment and embodiment 1 are basic identical, and its difference is that the upper end of described two seals 2 forms the semicircle end difference 23 that radially dwindles respectively as Fig. 7～shown in Figure 10; The shaft shoulder 231 places of described end difference 23 are provided with the inclination angle 2311 to its set terminal inclination; Between described locking part 3 and seal 2, further be provided with the clamping sleeve 6 of an annular, this clamping sleeve 6 is set in the end difference 23 of two seals 2, this clamping sleeve 6 forms the chamfering 61 (as shown in Figure 7) of flaring from inside to outside with the described shaft shoulder 231 contact jaws, this chamfering 61 identical with the angle of inclination at described inclination angle 2311 (in the present embodiment, the angle of inclination is 45 degree); The size of the pipe joint 71 that plug 81 that the aperture 62 of described clamping sleeve 6 connects more than or equal to described cable or pipeline connect.
As shown in the figure, because in the present embodiment, clamping sleeve 6 just is set in the end difference 23 of two seals 2, and clamping sleeve 6 is provided with the chamfering 61 and inclination angle 2311 that matches with the shaft shoulder 231 places of seal 2; As shown in Figure 7, when tightening locking part 3 downwards, locking part 3 is this clamping sleeve 6 of extruding downwards, make inclination angle 2311 radial compression described two seals 2 of the chamfering 61 of clamping sleeve 6 by seal 2, make seal 2 radial expansions, clamping cables 8 or pipeline 7 have been eliminated the gap between seal 2 and cable 8 or the pipeline 7, simultaneously also eliminated between two rubber seals and the gap between rubber seal 2 and the pedestal 1, reached good reliable sealing effect.
Other structures, operation principle and the beneficial effect of present embodiment is identical with execution mode 1, does not repeat them here.
The above only is the schematic embodiment of the utility model, is not in order to limit scope of the present utility model.Any those skilled in the art, equivalent variations of having done under the prerequisite that does not break away from design of the present utility model and principle and modification all should belong to the scope that the utility model is protected.
