[0025] Hereinafter, with reference to the attached drawings, the configuration and operational relationship of a rotary lantern with added waterproof performance according to one embodiment of the present invention will be examined in detail as follows.
[0026] FIG. 2 is an exploded perspective view showing a lantern with added waterproof performance according to the present invention, FIG. 3a and 3b are exploded perspective views showing a first waterproof part and a third waterproof part according to the present invention, and FIG. 4a and 4b are exploded perspective views showing a second waterproof part according to the present invention.
[0027] Referring to FIGS. 2 to 4b above, the configuration according to one embodiment of the present invention is largely composed of a body part (1100), a head part (1200), a protrusion part (1300), an insertion part (1400), a fixing pin (1500), a control circuit part (1600), a light-emitting part (1650), a first waterproof part (1700), a second waterproof part (1800), and a third waterproof part (1900).
[0028] First, the body part (1100) has a first rotational coupling surface (1110, see FIG. 3b) formed at an angle at the end.
[0029] Additionally, the head portion (1200) has a second rotational coupling surface (1210) formed at an inclined end that corresponds to and contacts the first rotational coupling surface (1110).
[0030] Additionally, the protrusion (1300) can be formed to protrude from either the first rotational coupling surface (1110) or the second rotational coupling surface (1210), but with reference to FIG. 2, according to one embodiment of the present invention, the protrusion (1300) is preferably formed on the second rotational coupling surface (1210) of the head portion (1200).
[0031] Here, the reason for placing and forming the protrusion (1300) on the second rotational coupling surface (1210) of the head part (1200) as described above is that, since the light-emitting part (1650) described later is embedded in the head part (1200), instead of forming an insertion part (1400) in the head part (1200) as in the prior art, the protrusion (1300) is placed and formed in the head part (1200) to secure the internal space of the head part (1200) in which the light-emitting part (1650) is embedded (i.e., it is designed to avoid the internal space of the head part being encroached upon by the insertion part when the insertion part is formed in a recess), and additionally, the heat generated from the light-emitting part (1650) can be better dissipated to the outside through the protrusion (1300).
[0032] In addition, the insertion part (1400) can also be formed on the other of the first rotational coupling surface (1110) or the second rotational coupling surface (1210) where the protrusion (1300) is not formed, but for the reasons mentioned above, with reference to FIG. 2, it is preferable that the insertion part (1400) be formed on the first rotational coupling surface (1110, see FIG. 3b) of the body part (1100) according to one embodiment of the present invention.
[0033] Additionally, the fixing pin (1500) selectively restricts the rotation of the protrusion (1300) while being fastened to the body part (1100) through the pin insertion hole (1910).
[0034] Additionally, the control circuit (1600) controls power supply and operation to the head unit (1200) through the protrusion (1300) while embedded in the body unit (1100).
[0035] According to one embodiment, the control circuit unit (1600) may be a printed circuit board (PCB) on which various electronic components are mounted to control the light-emitting unit (1650), battery (B), and switch (unmarked) described later.
[0036] Additionally, the light-emitting unit (1650) is provided in the head unit (1200) and emits light under the control of the control circuit unit (1600). According to one embodiment, the light-emitting unit (1650) may be an LED (Light Emitting Diode).
[0037] In addition, the present invention (1000) has a first waterproofing part (1700) for waterproofing the gap between the first rotational coupling surface (1110) and the second rotational coupling surface (1210).
[0038] Referring to FIGS. 3a and 3b, according to one embodiment, the first waterproof portion (1700) comprises: a first O-ring (1710) fitted around the protrusion (1300) in a state in which a protrusion (1300) is formed on the second rotational coupling surface (1210) of the head portion (1200) and an insertion portion (1400) is formed on the first rotational coupling surface (1110) of the body portion (1100); and a second O-ring (1720) fitted around the insertion portion (1400). Here, as shown in the drawings, it is preferable that the diameter of the second O-ring (1720) be formed larger than the diameter of the first O-ring (1710).
[0039] In addition, the present invention (1000) includes a second waterproofing part (1800) for waterproofing the control circuit part (1600).
[0040] Referring to FIG. 4a and 4b, according to one embodiment, the second waterproof member (1800) comprises: a first sealing member (1810) having an open top surface and accommodating the control circuit member (1600); and a second sealing member (1820) having a wire outlet (1821) formed at the top for pulling out a wire (not shown) of the control circuit member (1600) and sealing the open top surface of the first sealing member (1810) while the first sealing member (1810) accommodates the control circuit member (1600).
[0041] Additionally, the bottom surface of the first sealing member (1810) is open, and a spring electrode (1004a) coupled with a control circuit unit (1600) is connected through the open bottom surface. Therefore, since the spring electrode (1004a) is exposed to the outside through the open bottom surface of the first sealing member (1810), the positive terminal of the battery (e.g., dry cell) comes into contact with the spring electrode (1004a) and is electrically connected to the control circuit unit (1600).
[0042] Additionally, before the second sealing member (1820) is joined, a curable resin (not shown) is filled in the empty space inside the first sealing member (1810), excluding the control circuit section (1600), for waterproofing purposes, and as a result, the control circuit section (1600) accommodated between the first sealing member (1810) and the second sealing member (1820) is wrapped in the curable resin (not shown) and waterproofed. Here, the curable resin may be, for example, a thermosetting resin or a photocurable resin.
[0043] In addition, the present invention (1000) has a third waterproofing part (1900) for waterproofing the pin insertion hole (1910) into which the fixing pin (1500) is inserted.
[0044] Referring to FIG. 3a and 3b, according to one embodiment, the third waterproof portion (1900) may be a pin insertion hole (1910) of an outer tube structure in which a pin insertion hole (1910) into which a fixing pin (1500) is inserted is formed only on one side of the body portion (1100) without penetrating the body portion (1100). Additionally, it includes a weld sealing portion (1920) in which the fixing pin (1500) is fully inserted into the pin insertion hole (1910) and the fixing pin (1500) selectively restricts the rotation of the protrusion (1300), and in this state, the entrance of the pin insertion hole (1910) is sealed by metal welding.
[0045] For example, the weld seal (1920) can be formed by laser welding an aluminum alloy to the entrance of the pin insertion hole (1910).
[0046] For reference, in FIG. 1, the unexplained reference numeral 1001 refers to the optical guide part, 1002 to the housing part, 1003 to the cap part, and 1004b to the spring electrode.
[0047] Additionally, referring to FIG. 1, the bottom surface of the cap portion (1003) according to the present invention may be further provided with a permanent magnet (1006) for attaching a rotating lantern with waterproof performance according to the present invention to a steel structure, etc.
[0048] Accordingly, the rotary lantern (1000) with added waterproof performance according to the above configuration can be effectively utilized even in urgent fire suppression situations where a large amount of firefighting water must be sprayed in a dark environment. As a result, a very beneficial effect can be obtained in saving valuable lives, including firefighters, and property damage through rapid fire suppression.
[0049] Furthermore, the present invention is not limited solely to the embodiment described above. Since the same effect can be achieved even when the detailed configuration, number, or arrangement structure of the device is changed, it is hereby specified that those skilled in the art can add, delete, or modify various configurations within the scope of the technical concept of the present invention.
