Abstract
The utility model provides a waterproof structure for a flashlight lamp cap. The waterproof structure for the flashlight lamp cap comprises a lamp cap shell, a sealing ring, a lens and an outer cover, wherein a sealing groove is formed in the end face of the lamp cap shell, the sealing ring is arranged in the sealing groove, the lens is mounted on the end face of the lamp cap cover, the outer cover is connected to the end of the lamp cap shell, and the lens is pressed on the sealing ring through the outer cover. When assembling is carried out, the outer cover is mounted on the lamp cap shell, and the lens is pressed to the sealing ring tightly to form waterproof sealing. The waterproof performance of the lamp cap is improved, and the waterproof structure for the flashlight lamp cap has the advantages of being simple in structure and low in cost. In addition, when the waterproof structure for the flashlight lamp cap is applied under water, certain water pressure can act on the outer cover and the lens, thus the lens can be pressed to the sealing ring more tightly under the action of the water pressure, and sealing performance is improved.
Description
Technical field
The utility model relates to flashlight art, particularly a kind of waterproof construction of electric-torch burner.
Background technology
The lamp holder sealing property of flashlight of the prior art is bad, can not be applied to some specific occasions, for example under water.When using under water, water is easy to just enter lamp holder, thereby causes the damage of flashlight.
Utility model content
The utility model provides a kind of waterproof construction of simple in structure, cost is low, water resistance is good electric-torch burner.
For addressing the above problem, as an aspect of the present utility model, provide a kind of waterproof construction of electric-torch burner, comprising: shell of lamp base, is formed with seal groove on the end face of shell of lamp base; Sealing ring, is arranged in seal groove; Eyeglass, is arranged on the end face of shell of lamp base; Outer cover, be connected, and eyeglass is pressed on sealing ring by outer cover with the end of shell of lamp base.
Further, sealing ring is O shape circle.
Further, between outer cover and shell of lamp base, be threaded connection.
Further, the outer setting of shell of lamp base has circumferential groove in its end portion, is provided with shatter-resistant waterproof grommet in circumferential groove in its end portion, the end of outer cover and shatter-resistant waterproof grommet butt.
Further, shatter-resistant waterproof grommet is O shape circle.
During installation, outer cover is installed on shell of lamp base, thereby eyeglass is pressed on sealing ring tightly, to form waterproof sealing one.Thereby, improved the water resistance of lamp holder, there is feature simple in structure, cost is low.In addition, when the waterproof construction in the utility model is applied under water, on outer cover and eyeglass, can act on certain hydraulic pressure, like this, under the effect of hydraulic pressure, can make eyeglass more closely be pressed on sealing ring, thereby improve sealing property.
Accompanying drawing explanation
Fig. 1 schematically shows structural representation of the present utility model.
Reference numeral in figure: 1, shell of lamp base; 2, seal groove; 3, sealing ring; 4, eyeglass; 5, outer cover; 6, shatter-resistant waterproof grommet.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Please refer to Fig. 1, the utility model provides a kind of waterproof construction of electric-torch burner, comprising: shell of lamp base 1, is formed with seal groove 2 on the end face of shell of lamp base 1; Sealing ring 3, is arranged in seal groove 2; Eyeglass 4, is arranged on the end face of shell of lamp base 1; Outer cover 5, be connected, and eyeglass 4 is pressed on sealing ring 3 by outer cover 5 with the end of shell of lamp base 1.Preferably, sealing ring 3 is O shape circles.Preferably, between outer cover 5 and shell of lamp base 1, be threaded connection.
During installation, outer cover 5 is installed on shell of lamp base 1, thereby eyeglass 4 is pressed on sealing ring 3 tightly, to form waterproof sealing one.Thereby, improved the water resistance of lamp holder, there is feature simple in structure, cost is low.In addition, when the waterproof construction in the utility model is applied under water, on outer cover and eyeglass, can act on certain hydraulic pressure, like this, under the effect of hydraulic pressure, can make eyeglass more closely be pressed on sealing ring, thereby improve sealing property.
Preferably, the outer setting of shell of lamp base 1 has circumferential groove in its end portion, is provided with shatter-resistant waterproof grommet 6 in circumferential groove in its end portion, the end of outer cover 5 and shatter-resistant waterproof grommet 6 butts.Preferably, shatter-resistant waterproof grommet 6 is O shape circle.By the butt between shatter-resistant waterproof grommet 6 and outer cover 5, also can form one waterproof sealing, thereby, further improved the water resistance of lamp holder.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
