Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figures 2 and 3, anti-water column of the present utility model comprises a hollow cylinder 21, and the waterproof plug 22 that removably is inserted in hollow cylinder 21 1 ends and matches with these hollow cylinder 21 inwalls; The outer wall of this waterproof plug 22 is provided with outwardly at least one circle waterproof ring 221; Fill in hollow cylinder 21 when interior when waterproof plug 22, waterproof ring 221 closely is connected to the inwall of hollow cylinder 21, allows aqueous vapor be difficult for infiltrating in this hollow cylinder 21, so waterproof effect of the present utility model is better.In Fig. 2 and Fig. 3, waterproof ring 221 is a circle, but also can waterproof ring 221 be set to two circles or more according to actual conditions, can reach better waterproof effect, but can increase manufacturing cost.
In the drawings, the outer wall of waterproof plug 22 is also outwardly at least one locating ring 222, and the inwall of hollow cylinder 21 is provided with the location division 211 of matching with this locating ring 222, is difficult for getting loose after making waterproof plug 22 fill in hollow cylinder 21.In illustrated embodiment, the inwall of hollow cylinder 21 is provided with at least one step, the location division 211 of the cascaded surface of this step for matching with locating ring 222.This step can be the shape shown in the embodiment 1, also can for a projection that is projected on hollow cylinder 21 inwalls, can reach the purpose of blocking locating ring 222 equally.
Fill in when hollow cylinder 21 is interior when waterproof plug 22, waterproof ring 221 closely is connected to the inwall of hollow cylinder 21, and these locating ring 222 correspondences are stuck in 211 places, location division of hollow cylinder 21, and this location division 211 forms step-like drop with the inwall of hollow cylinder 21.Because the waterproof ring 221 on the anti-water column 20 closely is connected to the inwall of this hollow cylinder 21, allow aqueous vapor be difficult for infiltrating in this hollow cylinder 21, so the utlity model has better waterproof effect; Simultaneously locating ring 222 correspondences on the waterproof plug 22 are snapped in the location division 211 of this hollow cylinder 21, allow waterproof plug 22 location and be difficult for getting loose.
In order to reach better waterproof effect, the outer wall of described hollow cylinder 21 also is provided with at least one stage portion 212, and offers at least one waterproof groove 213 on the described stage portion 212.In conjunction with Fig. 4-shown in Figure 6, be provided with a stage portion 212 at the outer wall of hollow cylinder 21, this stage portion 212 is provided with a waterproof groove 213, this waterproof groove 213 be one around the annular recess of described hollow cylinder 21 outer walls.Aqueous vapor can be stranded in this waterproof groove 213, so that should possess better waterproof effect by anti-water column 20.
The quantity of stage portion 212 is not limited to shown in the embodiment 2, also can possess two as shown in Figure 8, can be detained more aqueous vapor in waterproof groove 213, reaches better waterproof effect.What certainly its quantity also can be for more than three or three is more.
In order conveniently to extract waterproof plug 22, the outer wall of hollow cylinder 21 is provided with step 214 at an end that inserts described waterproof plug 22, can conveniently adopt hand or instrument that waterproof plug 22 is extracted.Locating ring 222 is deformable elastomer, on the one hand can keep closely combination with hollow cylinder 21, can guarantee that on the other hand waterproof plug 22 can extract from hollow cylinder 21.One end of described waterproof plug 22 inserts in the hollow cylinder 21, and the other end exposes to outside the described hollow cylinder, and an end vertical section of exposing is T-shaped, or similar mushroom, can further facilitate and extract waterproof plug 22.
Application structure schematic diagram as shown in Figure 7, when power supply casing 16 adopted waterproofing design or encapsulating 15, this waterproof plug 22 was filled in this hollow cylinder 21, and on the variable resistor 13 with these hollow cylinder 21 socket circuit boards 14, encapsulating 15 is in the outside of anti-water column 20 again.Waterproof ring 221 closely is connected to the inwall of this hollow cylinder 21, allows aqueous vapor be difficult for infiltrating in this hollow cylinder 21, can prevent effectively that sealing directly penetrates on the variable resistor 13 of circuit board 14.Owing to during variable resistor 13 actual the use, sometimes needing the adjusting resistance value, so waterproof plug 22 can be extracted.When adjusting resistance, can open waterproof plug 22 conveniently to adjust resistance.So in the time of on anti-water column 20 sockets and the variable resistor 13, not only can reach the purpose of waterproof but also be convenient to adjust resistance.So the utility model also proposes a kind of electronic product, be provided with described anti-water column 20 on the circuit of described electronic product.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
