As shown in Figure 2, the second is at a caisson 4 of explosion-proof audio-enlarging telephone 3 outside installings, the water-proof function of realizing explosion-proof audio-enlarging telephone 3 by housing and the sealing ring between cap of caisson 4.But the installation of caisson 4 has increased totally taking up room of explosion-proof audio-enlarging telephone, and complex installation process, also reduced the aesthetics of telephone set.
Utility model content
The technical problems to be solved in the utility model is in order to overcome the defect that in prior art, the water-tight device of explosion-proof audio-enlarging telephone takes up room greatly, installation cost is high, and a kind of explosion-proof audio-enlarging telephone of the water-tight device of explosion-proof audio-enlarging telephone simple, easy to use, with low cost being installed and being contained it is provided.
The utility model is to solve above-mentioned technical problem by following technical proposals: a kind of water-tight device of explosion-proof audio-enlarging telephone, comprise a telephone case and a telephone set cap, its feature is: the junction, top of described telephone case and described telephone set cap is provided with a labyrinth seal structure.
Preferably, the junction, bottom of described telephone case and described telephone set cap is also provided with the labyrinth seal structure described in.
Preferably, described labyrinth seal structure comprises the concave station being formed on described telephone case, and is formed at the overlap that described telephone casing covers, the staggered overlap joint of this concave station and this overlap.
Preferably, between this concave station and this overlap, be provided with at least one sealing strip.
Preferably, described sealing strip is foamed silica gel sealing strip.Described foamed silica gel sealing strip is commercially available obtaining.
Preferably, described water-tight device also comprises the seal at least one contact-making surface that is positioned at described telephone case and described telephone set cap, and described seal is embedded at described telephone casing and covers.
Preferably, described seal is foamed silica gel seal.Described foamed silica gel seal is commercially available obtaining.
The utility model also provides a kind of explosion-proof audio-enlarging telephone, and it comprises the water-tight device of explosion-proof audio-enlarging telephone as above.
Positive progressive effect of the present utility model is: the water-tight device of the explosion-proof audio-enlarging telephone that the utility model provides can guarantee that the degree of protection of explosion-proof audio-enlarging telephone is not less than IP65, and it installs simple, easy to use, with low cost.

Fig. 3 is the profile of explosion-proof audio-enlarging telephone of the present utility model.
Fig. 4 is the structure enlarged drawing of the water-tight device A part in Fig. 3.
Embodiment
Lift two preferred embodiments below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
As shown in Figure 3, the water-tight device of explosion-proof audio-enlarging telephone of the present utility model is arranged at the top of explosion-proof audio-enlarging telephone.As shown in Figure 4, the water-tight device of explosion-proof audio-enlarging telephone comprises telephone case 1, telephone set cap 2, labyrinth seal structure 3 and seal 4.
Described labyrinth seal structure 3 comprises the concave station being formed on described telephone case 1, and is formed at the overlap on described telephone set cap 2, the staggered overlap joint of this concave station and this overlap.This design interlaced, that be similar to ledge structure, can reduce the impact of rainwater pressure to telephone case 1 and telephone set cap 2, and can effectively reduce the invasion amount of rainwater.
In addition, between this concave station and this overlap, be also provided with at least one sealing strip.If rainfall is excessive, rainwater can not get effectively getting rid of and cleaning in time, still has a small amount of rainwater and flows in explosion-proof audio-enlarging telephone along the gap of concave station and overlap.If explosion-proof audio-enlarging telephone makes moist for a long time, be easy to cause short circuit, produce potential safety hazard.The sealing strip being now arranged between concave station and overlap has just been brought into play important function.It is one-body molded that sealing strip waters foam process by line, and telephone case 1 and telephone set cap 2 are closely linked together, and not only played the effect of secondary waterproof, also realized the abundant sealing of explosion-proof audio-enlarging telephone.
In addition, be also at least provided with a seal 4 on the top contact-making surface of described telephone case 1 and described telephone set cap 2, described seal 4 is embedded on described telephone set cap 2.Seal 4 has been reinforced the faying face of 2 of telephone case 1 and telephone set caps, has played the effect of triple waterproof, has fundamentally avoided operational failure.
Described seal 4 is a foamed silica gel seal, adopts conventional line to water foam process and processes.Line waters foam process and refers to blowing agent is filled in to the gap between telephone case and telephone set cap, by controlling expansion rate and foamed time, monitors foaming degree, guaranteeing that gap fully foamed while tamping by blowing agent, stops foaming process.
The water-tight device of the explosion-proof audio-enlarging telephone that the present embodiment provides is installed simple, easy to use, with low cost, and can guarantee that the degree of protection of explosion-proof audio-enlarging telephone is not less than IP65.Wherein, IP grade be shell for explosion-proof electric apparatus or water proof and dust proof electrical equipment to allotrylic degree of protection, its latter linked two numerals represent respectively dustproof grade, classification of waterproof, larger its degree of protection of numeral is better.Degree of protection IP65 represents, the explosion-proof hands free telephone function that the utility model provides prevents that dust from entering completely, and water rinses without any injury.
The difference of the present embodiment and embodiment 1 is: the water-tight device that is also provided with a set of explosion-proof audio-enlarging telephone in the bottom of the junction of telephone case 1 and telephone set cap 2.Specifically as shown in B part in Fig. 3.This water-tight device comprises the labyrinth seal structure of the junction that is positioned at described telephone case 1 and described telephone set cap 2, and is positioned at the seal on the contact-making surface of telephone case 1 and described telephone set cap 2.
Other parts and the function of the present embodiment are identical with embodiment 1.Adopt the present embodiment can further guarantee reliably that the degree of protection of explosion-proof audio-enlarging telephone is not less than IP65, and therefore not to repeat here.
Although more than described embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection range of the present utility model is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these execution modes, but these changes and modification all fall into protection range of the present utility model.
