The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, the present invention provides a multifunctional emergency work light 10, comprising: the lamp holder 100 and a plurality of lamp panels 200, the lamp panels 200 are the illumination components on the multifunctional emergency working lamp 10, the lamp holder 100 provides electric energy for the lamp panels 200 and controls the lamp panels 200 to be turned on and off, the lamp panels 200 are distributed in a circumferential array with the lamp holder 100 as the center, each lamp panel 200 is rotatably connected with the lamp holder 100, and each lamp panel 200 can rotate around the lamp panel and the lamp holder 100 to adjust the illumination angle.

Referring to fig. 3 and 4, the connection position between the lamp panel 200 and the lamp socket 100 is provided with: the three-way rotary shaft 300, the first clamping block 400 and the second clamping block 500. The three-way rotating shaft 300 comprises a main pipe 310 and an auxiliary pipe 320, wherein a first fluted disc 311 is arranged on the main pipe 310, a second fluted disc 321 is arranged on the auxiliary pipe 320, the main pipe 310 is rotationally connected with the lamp holder 100, the first fluted disc 311 is positioned in the lamp holder 100, the auxiliary pipe 320 is rotationally connected with the lamp panel 200, and the second fluted disc 321 is positioned in the lamp panel 200; that is, the three-way rotary shaft 300 is a member connecting the lamp socket 100 and the lamp panel 200.

The principle of fixing the multifunctional emergency work lamp 10 by using the trigger knob 800 and the G-shaped hook 700 in different working environments is described as follows:

1. when the portable lamp is used as a portable lamp in a specific position of the inspection fault:

referring to fig. 8, the thumb and the index finger cooperate to clamp the narrow edge of the trigger protrusion 810, and twist the trigger knob 800, so that the trigger protrusion 810 is staggered with the trigger section 732 on the G-shaped hook 700, at this time, the elastic force of the reset elastic member 900 no longer acts on the G-shaped hook 700, the arc-shaped hook 710 is shifted to enable both hooks to be turned to be perpendicular to the surface of the lamp holder 100, at this time, the arc-shaped hook 710 on the two G-shaped hooks 700 form a hanging ring at the bottom of the lamp holder 100, the fingers of the user stretch into the arc-shaped hook 710 to lift the multifunctional emergency work lamp 10, and the multifunctional emergency work lamp can be used as a portable lamp, at this time, the G-shaped hook 700 cannot be automatically reset due to the elastic force of the reset elastic member 900, at this time, the two G-shaped hooks 700 are kept in a closed state under the self gravity of the multifunctional emergency work lamp 10, so that the two hands are convenient to extract, and uncomfortable feeling is not generated due to the elastic force of the reset elastic member 900, so as to provide a good use experience.

2. When the multifunctional emergency work lamp 10 needs to be hung due to the lack of bottom support, the multifunctional emergency work lamp 10 needs to be hung on the temporary hanging piece 11, and under the use condition:

referring to fig. 13, the trigger knob 800 is screwed to keep the trigger protrusion 810 in contact with the trigger sections 732 of the two G-shaped hooks 700, in this state, the index finger and the thumb respectively hook the arc-shaped hooks 710 on the two G-shaped hooks 700, the curved finger hooks the arc-shaped hooks 710 from the receiving slot 140, the thumb and the index finger are gathered together to drive the two G-shaped hooks 700 to rotate simultaneously until the two arc-shaped hooks 710 are gathered together, the temporary hanging piece 11 is penetrated into the two arc-shaped hooks 710, the finger applied to the two G-shaped hooks 700 is removed, at this time, the reset elastic piece 900 stretches to provide elastic force to lift the trigger knob 800 along the mounting hole 150, the arc-shaped hooks 710 on the two G-shaped hooks 700 are driven to separate from each other, and the temporary hanging piece 11 is clamped. At this time, the two arc-shaped hooks 710 and the bottom of the lamp holder 100 are tightly attached to the temporary hanging member 11, so as to hang the multifunctional emergency working lamp 10, and at this time, the two G-shaped hooks 700 are in a state as shown in fig. 7. In this state, the two arc-shaped hooks 710 clamp the upper side of the temporary hanging member 11, and the bottom of the lamp holder 100 clamps the lower side of the temporary hanging member 11, so as to prevent the multifunctional emergency work light 10 from shaking and even sliding on the temporary hanging member 11 due to vibration generated during the construction process.

3. The construction site can provide bottom support conditions (such as ground, surface of construction equipment, etc.), when the multifunctional emergency work lamp 10 needs to be placed to provide illumination:

referring to fig. 14, when the vibration of the supporting location 12 is small or the multifunctional emergency work lamp 10 is not affected, the multifunctional emergency work lamp 10 is directly placed on the supporting location 12;

in the case where the vibration of the supporting site 12 is large or the construction process easily causes the multifunctional emergency work lamp 10 to be deviated:

first, a recessed portion 13 (e.g., a gap between adjacent members on construction equipment, a pit on the ground, etc.) is found on a supporting site 12

Then, the trigger knob 800 is screwed to make the trigger protrusion 810 contact with the two G-shaped hooks 700, in this state, the index finger and the thumb hook the arc-shaped hooks 710 on the two G-shaped hooks 700 respectively, the arc-shaped hooks 710 are hooked from the storage groove 140 by the curved finger, and the two arc-shaped hooks 710 are driven to be close to each other by the real force;

when the distance between the two arc-shaped hook bodies 710 is smaller than the width of the concave part 13, the two arc-shaped hook bodies 710 extend into the concave part 13 and release fingers, at the moment, the reset elastic piece 900 extends, the trigger knob 800 pops up under the elastic force provided by the reset elastic piece 900, the trigger protrusion 810 on the trigger knob 800 pushes the two G-shaped hooks 700 to reset, so that the two arc-shaped hook bodies 710 are far away from each other, and the two arc-shaped hook bodies 710 are pushed against the inner wall of the concave part 13;

then the lamp holder 100 is pressed down until the bottom of the lamp holder 100 is horizontally placed on the supporting place 12, at this time, the reset elastic piece 900 provides elastic force to enable the two arc-shaped hook bodies 710 to support the inner wall of the concave part 13, so that the multifunctional emergency working lamp 10 is prevented from deviating from the fixed position due to vibration generated in the construction process, and stable illumination is provided for a user;

when the medicine is to be taken out, the medicine is directly pulled out, and the operation is simple.

Through setting up G shape couple 700, trigger knob 800 and reset elastic member 900 in lamp stand 100 bottom, at the body structure of guaranteeing multi-functional emergency work lamp 10 for multi-functional emergency work lamp 10 can fix under multiple different operational environment, provides stable lighting condition.
