Abstract
The utility model discloses an immediate balancing technology for internal air pressure and external air pressure of a lamp with a sealed structure. The immediate balancing technology for the internal air pressure and the external air pressure of the lamp with the sealed structure comprises an air pressure balancing mechanism which is communicated with a lamp body of the lamp, wherein the air pressure balancing mechanism comprises at least one set of flexible film made of flexible materials which are waterproof and airtight, the flexible film is communicated with the lamp body through a port mechanism, and can expand or contract according to changes of the air pressure inside the lamp body, the internal air pressure of the lamp body can be immediately adjusted, immediate balance between the internal air pressure and the external air pressure of the lamp can be achieved, and the problem that water is sucked into the lamp body due to the fact that the difference between the internal air pressure and the external air pressure of the lamp exists is solved. In addition, due to the facts that the flexible film is communicated with the lamp body, and air inside the lamp body cannot carry out exchange with air of the outside in the process of the changes of the internal air pressure of the lamp body and the process of immediate adjustment, changes of the external environment cannot have an influence on the air pressure balancing mechanism, the structure is simple, and pressure adjustment performance is reliable.
Description
Technical field
The utility model relates to the instant balancing technique of a kind of hermetically-sealed construction light fixture inner and outer air pressure.
Background technology
Present light fixture lamp body can be arranged to a structure with certain sealing property usually, so that water proof and dust proof, but such light fixture is because its sealing property of needs of cost and mounting design can not arrange get Tai Gao, when if the temperature of lamp body inside changes, as light fixture is used the temperature difference when stopping using, the temperature difference while raining suddenly when outdoor use shines upon etc., now, the air of lamp body inside can expand with heat and contract with cold, particularly during shrinkage, the lamp body internal air pressure descends, cause water to be inhaled into, after long-term the use, there will be ponding in lamp body, the use that affects light fixture even damages light fixture, although at present for avoiding the appearance of this situation, one vent valve or ventilated membrane can be set on lamp body, but can there be certain difference in activation pressure in such vent valve or ventilated membrane, and the instant balance that the restriction that is subject to ventilative speed more is difficult to accomplish pressure, still the situation of water suction infiltration can appear because of negative pressure, and after long-time the use, vent valve or ventilated membrane there will be laying dust, affect the permeability of vent valve or ventilated membrane.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of hermetically-sealed construction light fixture inner and outer air pressure instant balancing technique, can realize the instant balance of light fixture lamp body inner and outer air pressure, and not be subject to ectocine, and simple in structure, reliability is high.
The utility model solves the technical scheme that its technical problem adopts:
The instant balancing technique of a kind of hermetically-sealed construction light fixture inner and outer air pressure, comprise the air pressure balance mechanism with light fixture lamp body internal communication, described air pressure balance mechanism comprises at least one group of flexible membrane of being made by the flexible material of both water tight and air tight, described flexible membrane is by an interface agency and lamp body internal communication, and described flexible membrane can change and expands or shrink according to the pressure of lamp body internal gas.
Described flexible membrane is a bag-shaped air bag.
Described interface agency comprises the mouthpiece that is arranged on bag-shaped air bag opening place and is communicated with bag-shaped inside air bag, and described lamp body offers the interface that also can be connected with mouthpiece with the inner conducting of lamp body.
Described mouthpiece is connected by threaded engagement with interface, on described mouthpiece, is provided with external screw thread, is provided with the internal thread corresponding with the external screw thread of mouthpiece in described interface.
Be provided with a nut portions on described mouthpiece.
Be arranged with a collision mat on described mouthpiece.
Described mouthpiece is made by plastic material, and described bag-shaped air bag and mouthpiece are made by secondary injection molding.
Described bag-shaped air bag is made by nylon material.
Described bag-shaped balloon surface is provided with nano coating.
The beneficial effects of the utility model are: due to the flexible membrane be provided with the inner conducting of lamp body, this flexible membrane can change and expands or shrink according to the pressure of lamp body internal gas, air pressure in adjusting lamp body that can be instant, make the inside and outside air pressure of light fixture realize instant balance, prevent because the draught head inside and outside light fixture produces infiltration, in addition, the inner conducting of flexible membrane and lamp body, in the variation of lamp body air pressure inside and instant adjustment process, can do not exchanged with extraneous gas, therefore the variation of external environment condition can not make air pressure balance mechanism is exerted an influence, and simple in structure, pressure regulating performance is reliable.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is decomposing schematic representation of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 1, Fig. 2 is the structural representation of a specific embodiment of the utility model, as shown in the figure, the instant balancing technique of a kind of hermetically-sealed construction light fixture inner and outer air pressure, comprise the air pressure balance mechanism with light fixture lamp body 1 internal communication, described air pressure balance mechanism comprises one group of flexible membrane of being made by the flexible material of both water tight and air tight, in the present embodiment, the bag-shaped air bag 21 of flexible membrane for by surface coverage, having the nylon material of nano coating to make, certainly in specific implementation process, bag-shaped air bag 21 also can adopt leather, the flexible materials such as plastic foil are made, and when being assemblied in to lamp body 1, bag-shaped air bag 21 discharges bag-shaped air bag 21 all gas, now the reserved volume of bag-shaped air bag 21 is as holding the required volume of the interior gas expansion of lamp body 1 and the volume of required supplementary extraneous air while shrinking, the reserved volume of bag-shaped air bag 21 is greater than expansion and the amount of contraction of the interior gas volume of lamp body 1 when extreme changes of temperature, make this bag-shaped air bag 21 to change and expand or shrink according to the pressure of lamp body 1 internal gas, especially lamp body 1 internal gas pressure is because of low temperature during lower than external atmosphere pressure, air bag can be inhaled in lamp body, allow outside air add to lamp body, air pressure in instant adjusting lamp body 1, make the inside and outside air pressure of light fixture realize instant balance, prevent because the draught head inside and outside light fixture produces the water suction phenomenon, in addition, bag-shaped air bag 21 and the inner conducting of lamp body 1, in lamp body 1 air pressure inside variation and instant adjustment process, can do not exchanged with extraneous gas, therefore the variation of external environment condition is as laying dust, ponding etc. all can not make air pressure balance mechanism is exerted an influence, and simple in structure, pressure regulating performance is reliable.
