Abstract
The invention discloses a waterproof device comprising a bearing component, an expansion component, a telescopic structure, a switching component, and a clamping component. The switching component compresses the communication space of the bearing component and the expansion component to make the expansion component expand into a bulge on the outer or inner surface of the bearing component, and then, the expansion component extrudes a cable/pipe inward or extrudes a wall body outward to form a sealed state and block the flow of water. While compressing the space, the switching component extrudes the clamping component and makes the clamping component move outward to clamp the inner walls of the holes in the wall body so as to fix the whole device. The telescopic structure rotates through the bearing component to stretch out or draw back so as to change the length of the device, so the device adapts to wall bodies of a variety of thicknesses.

Hole 104 extrudes the first bulge 201 outward expansion;Air pressure extrudes the second expansion by inner core intercommunicating pore 105
Portion 202 inward expansion, is formed and seals water-proof function.
As shown in figure 11, the clamping block 502 of clamping unit 500 include being set in right-hand member clamping projection 504,
It is arranged on the clamping shaft 505 of left end, the clamping inclined-plane 504a of protruding 504 sides of clamping and is arranged on right-hand member
The clamping teeth 506 on top, clamping unit 500 is arranged on load bearing component 100 near switch block 400 side,
Clamping block 502 is flexibly connected by clamping shaft 505 and clamping axis hole 503 and is arranged in clamping slot 501, card
Tight block 502 can rotate in clamping slot 501, when switch block 400 does not arrives at clamping slot 501,
Being extruded by hole wall on wall, clamping block 502 exposes the inner surface of left carrying urceolus 101a left end, works as switch
Parts 400 motion comes, and the clamping that the pressing body 401 of switch block 400 extrudes in clamping projection 504 is oblique
Face 504a so that clamping block 502 moves out around clamping shaft 505, the clamping teeth 506 of clamping block 502 to
Hole wall on outer motion clamping wall, so that in water-tight device clamping hole on the wall.
As shown in figure 12, the second bulge 202 is the flexible material of circular tube shaped, and its both sides can be by glutinous
Patch is fixed on outside carrying inner core 102, it is also possible to be fixed on carrying by the second ring for fixing 203b of hard
In the interior mounting groove 107 of inner core 102, interior mounting groove 107 is wider than the step annular groove of inner side, circle for outside
Second ring for fixing 203b of cast by the second bulge 202 both sides by being pressed abd fixed on interior mounting groove 107
Step on so that the second bulge 202 with carrying inner core 102 seal, because the second bulge 202 is not
Fixing middle part is connected with inner core intercommunicating pore 105, so, when channel space 103 air pressure is big when, gas
Pressure can extrude the middle part of the second bulge 202 by inner core intercommunicating pore 105 so that in the second bulge 202
Portion forms the projection that a circle is soft, extruded cable, is formed and seals water-proof function.
See Figure 16-18, and shown the cooperation details of stretching structure 300 by partial enlarged drawing, such as figure
3, shown in 4,5,8,9 and 16-18,
Left carrying urceolus 101a is located at the clamping block 306 of the sticking department 302 of 101a-1 side, outer expansion section,
The clamping block 306 of strip comprises the locking of the 101a-1 medial wall, inwardly projecting outer expansion section being positioned at two
Protruding 306a and locking pressing plate 306b, clamping block 306 is fixed by the fixed strip 306c of diameter 0.5-5mm
Outside on the 101a-1 of expansion section, locking projections 306a and locking pressing plate 306b in fixed strip 306c both sides in
" seesaw " shape, presses down on locking pressing plate 306b, and locking projections 306a just moves upward.
Right carrying urceolus 101b is located at the outer lock slots 307 reducing the superolateral sticking department of portion 101b-1 302,
Start locking projections 306a to be positioned in lock slots 307, owing to lock slots 307 blocks fixed protruding 306a, make
Obtain right carrying urceolus 101b and left carrying urceolus 101a can not rotate against, press down on locking pressing plate 306b,
Locking projections 306a just moves upward and departs from lock slots 307, right carrying urceolus 101b and left carrying urceolus 101a
Can rotate against.
The internal diameter of interior expansion section 102a-1 reduces the external diameter of portion 102b-1 in being slightly larger than, inside reduce portion 102b-1
In interior expansion section 102a-1, air-tight movable connects, and left carrying inner core 102a and right carrying inner core 102b leads to
Expansion section 102a-1 and the interior portion 102b-1 that reduces is flexibly connected flexible and moves in crossing.
It is provided with stretching structure 300 orbit portion 301 inside the interior expansion section 102a-1 of left carrying inner core 102a
Long rails 303 and cross track 304, long rails 303 is for be arranged on outside interior expansion section 102a-1
Groove-like length direction groove, the cross track 304 of several groove-like intersects vertically with long rails 303,
Material is thus formed much more horizontal vertical grooved tracks, flexible slide block 305 in a cross track 304, phase
Right carrying inner core is driven to rotating left carrying urceolus 101a and right carrying urceolus 101b, right carrying urceolus 101b
Flexible slide block 305 on 102b slides in cross track 304, and flexible slide block 305 is at a cross track
After sliding into long rails 303 in 304, relatively pull left carrying urceolus 101a and right carrying urceolus 101b,
When flexible slide block 305 slides into second cross track 304 position in long rails 303, reversely rotate
Left carrying urceolus 101a and right carrying urceolus 101b, slide block enters second cross track 304, thus can
Water-tight device is elongated or shortens, to adapt to the body of wall of different-thickness.
See Figure 13-15, do not extrude for switch block 400, swelling part 200 do not have expand state,
And show that clamping unit 500 and swelling part 200 coordinate details by partial enlarged drawing.
See Figure 19 and Figure 20, inwardly extrude for switch block 400, swelling part 200 expand after and
The state that stretching structure 300 elongates, and after showing that clamping unit 500 is displaced outwardly by partial enlarged drawing
Cooperation details.
As shown in Figure 13-15,19,20, rotate swivel head 403 with spanner and rotate forward switch block 400,
Switch screw thread 402 coordinates with the thread-rolling screw 108 of left carrying inner core 102a and travels forward, driving switch portion
The pressing body 401 of part 400 extrudes inside channel space 103, and the pressing body 401 of switch block 400 squeezes
Clamping inclined-plane 504a in pressure clamping projection 504 so that clamping block 502 moves out around clamping shaft 505,
The clamping teeth 506 of clamping block 502 moves out hole wall on clamping wall, so that water-tight device is clamped on wall
In upper hole, pressing body 401 inward squeezing passage space 103 so that channel space 103 air pressure increases,
Air pressure extrudes the first bulge 201 outward expansion by urceolus intercommunicating pore 104, and air pressure passes through inner core intercommunicating pore
105 extruding the second bulge 202 inward expansion, are formed and seal water-proof function, when this device removed by needs,
Only need to rotate swivel head 403 with spanner and reversely rotate switch block 400, drive the extruding of switch block 400
Body 401 moves out, and channel space 103 air pressure declines, and the first bulge 201 and second can be made swollen
Swollen portion 202 shrinks, and continues direction and rotates swivel head 403, until pressing body 401 leaves clamping projection 504
On clamping inclined-plane 504a, clamping teeth 506 is not holding out against the inwall in hole on body of wall, just can take off device.
The preferred embodiment of the present invention described in detail above.Should be appreciated that the ordinary skill of this area
Personnel just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all
Technical staff passes through logical analysis the most on the basis of existing technology, pushes away in the art
Reason or the limited available technical scheme of experiment, all should be at the protection model being defined in the patent claims
In enclosing.
