[0045] See also Figure 1 and Figure 3 The present invention provides a portable lifting work lamp 10, including: a lamp head 100, a telescopic rod 200, a portable electrical box 300 and a plurality of tripods 400.

[0046] See also Figure 3 and Figure 4 A hinge seat 210 is disposed at the bottom of the telescopic rod 200, and a plurality of tripods 400 are rotatably connected to the hinge seat 210, and the plurality of tripods 400 are arranged in a circular array with the telescopic rod 200 as the center. Figure 4 The lamp head 100 is arranged on the top of the telescopic rod 200; the tripod 400 can rotate around the hinge seat 210. Specifically, after the multiple tripods 400 rotate toward the side away from the telescopic rod 200, the tripod 400 enters the unfolded state. At this time, the multiple tripods 400 are radially arranged with the telescopic rod 200 as the center. One end of each tripod 400 away from the telescopic rod 200 serves as a supporting point to provide support for the telescopic rod 200 to prevent the portable lifting work lamp 10 from tipping over; after the multiple tripods 400 rotate toward the side close to the telescopic rod 200, the tripod 400 enters the retracted state. At this time, the tripod 400 fits with the outer wall of the telescopic rod 200, reducing the overall volume of the portable lifting work lamp 10 for easy carrying out.

[0047] See also Figure 2 and Figure 3 Preferably, a retaining ring 230 is provided on the outer wall of the telescopic rod 200, and a plurality of buckles 231 are provided on the outer side of the retaining ring 230, and each buckle 231 is used to dock with a tripod 400. When the tripod 400 is switched to the retracted state, the buckle 231 buckles the tripod 400, so that the tripod 400 remains in contact with the outer wall of the telescopic rod 200, preventing the tripod 400 from rotating during transportation, thereby improving the structural stability of the portable lifting work light 10.

[0048] See also Figure 4 , an electrical connector 211 is provided on the hinge seat 210; the portable electrical appliance box 300 includes a box body 310 and a wiring row 320, a spare cable and a battery pack 330 accommodated in the box body 310, and an electrical socket 311 (such as Figure 1 As shown), the spare cable is used to connect the electrical socket 311 and the electrical connector 211.

[0049] An electrical connector 211 is provided on the hinge seat 210, and an electrical socket 311 is provided on the outer side of the box body 310. Before starting the portable lifting work lamp 10, the two ends of the spare cable are respectively connected to the electrical socket 311 and the electrical connector 211, and the lamp head 100 is electrically connected to the battery pack 330 in the portable electrical box 300 through the spare cable, and the battery pack 330 provides power to the lamp head 100.

[0050] The lamp head 100, telescopic rod 200 and tripod 400 form the main body of the work lamp, which is electrically connected to the portable electrical box 300 only through a spare cable. Therefore, when carrying the work lamp out, the spare cable is removed and the lamp head 100, telescopic rod 200 and tripod 400 form the main body of the work lamp and the portable electrical box 300 are separated. The user holds the main body of the work lamp composed of the lamp head 100, telescopic rod 200 and tripod 400 with one hand and holds the portable electrical box 300 with the other hand, that is, the portable electrical box 300 and the main body of the work lamp composed of the lamp head 100, telescopic rod 200 and tripod 400 can be carried separately. Preferably, a grip 240 is provided on the outer wall of the telescopic rod 200, and the grip 240 provides a gripping position to facilitate the user to carry the portable lifting work lamp 10.

[0051] Since the power source (portable electrical box 300) is external, there is no need to set up a power source in the lamp head 100 for power supply. Since the portable electrical box 300 and the lamp head 100, the telescopic rod 200 and the tripod 400 form the working lamp body and can be carried separately, that is, the volume of the battery pack 330 in the portable electrical box 300 is not limited by the volume of the lamp head 100, a large-capacity battery pack 330 can be set to meet the long-term lighting needs of the lamp head 100.

[0052] Compared with the prior art, the portable lifting work light 10 disclosed in the present invention has at least the following beneficial effects:

[0053] 1. The battery pack 330 of the portable electrical box 300 serves as an independent power source for the lamp head 100, so that the work lamp does not need to be bound to a generator and can provide stable lighting in outdoor scenes where electricity cannot be connected;

[0054] 2. The portable electrical box 300 and the lamp holder 100 are independent of each other and are electrically connected via a spare cable. The lamp holder 100 and the portable electrical box 300 can be disassembled and carried separately, which is convenient to carry.

[0055] See also Figure 3 In one embodiment, the telescopic rod 200 is a hollow structure, and a wire 500 is placed in the telescopic rod 200. The wire 500 is spiral, and the wire 500 is in contact with the inner wall of the telescopic rod 200. The two ends of the wire 500 are electrically connected to the lamp holder 100 and the electrical connector 211 respectively. Specifically, the wire 500 is spirally arranged to accommodate a longer length in the telescopic rod 200. When the telescopic rod 200 is in a retracted state, the wire 500 is spirally wound. When the telescopic rod 200 is extended, the wound portion of the wire 500 is stretched, that is, the wire 500 is synchronously extended (or contracted) with the telescopic rod 200.

[0056] See also Figure 3In one embodiment, the lamp holder 100 includes a lamp housing 110, an LED light board and a fan 120. The LED light board is accommodated in the lamp housing 110, and the fan 120 is disposed on the outer wall of the lamp housing 110. Preferably, a heat dissipation fin 111 is disposed on one side of the lamp housing 110 close to the fan 120. The battery pack 330 and the lamp holder 100 are separated in design, and the fan 120 cooperates with the heat dissipation fin 111 to dissipate heat from the LED light board, thereby improving the heat dissipation efficiency and enabling the LED light board to operate stably for a long time.

[0057] See also Figure 3 Furthermore, the lamp holder 100 further includes an angle adjustment bracket 130, a corrugated spring washer and a knob 140 (such as Figure 1 As shown in the figure, the angle adjustment bracket 130 is arranged on the outer wall of the lamp housing 110, a U-shaped bracket 220 matching the angle adjustment bracket 130 is arranged on the top of the telescopic rod 200, the knob 140 passes through the angle adjustment bracket 130 and the U-shaped bracket 220, and the corrugated spring pad is located between the angle adjustment bracket 130 and the U-shaped bracket 220. The angle adjustment bracket 130 and the U-shaped bracket 220 are locked by the knob 140, and the direction of the LED lamp board can be adjusted when the knob 140 is loosened, and the corrugated spring pad is arranged between the angle adjustment bracket 130 and the U-shaped bracket 220, and the resistance is increased to overcome the weight of the lamp head 100 itself, so as to prevent the lamp head 100 from falling, so as to facilitate the adjustment of the direction of the lamp head 100.

[0058] See also Figure 5 In one embodiment, the box body 310 includes a flip cover 312, a partition 313 and a storage box 314. The flip cover 312 is rotatably arranged on the storage box 314. The partition 313 is arranged in the inner cavity of the storage box 314. The terminal block 320 and the battery pack 330 are both located below the partition 313. The partition 313 divides the storage box 314 into two layers, the lower layer below the partition 313, the terminal block 320 and the battery pack 330 are located in the lower layer, and the upper layer above the partition 313 is the upper layer. The upper layer provides space for storing spare cables and tools such as wrenches. When the flip cover 312 is opened, only the tools located in the upper layer space are exposed, so that the portable electrical box 300 has the ability to store tools. The partition 313 will protect the terminal block 320 and the battery pack 330 located in the lower layer.

[0059] Preferably, the portable electrical box 300 further includes a start button 340 , which is disposed on the storage box 314 . After the portable electrical box 300 is connected to the lamp holder 100 via a spare cable, the lamp holder 100 can be lit by pressing the start button 340 .

[0060] See also Figure 4 and Figure 6It should be noted that when the multiple tripods 400 are unfolded, they are in contact with the ground to provide support for the portable lift work light 10, that is, the tripods 400 need to bear the weight of the portable lift work light 10. Since the tripods 400 and the hinge base 210 are rotatably connected, it is necessary to ensure that the tripods 400 will not flip over when bearing the weight of the portable lift work light 10. If one of the tripods 400 deflects, the portable lift work light 10 will fall over. In order to solve the problem of unstable support of the tripods 400, the tripods 400 include a load-bearing rod 410, a connecting head 420, a torsion spring 430 and a locking member 440.

[0061] See also Figure 6 The hinge base 210 is provided with a plurality of docking portions 212, and the number of the docking portions 212 is the same as the number of the tripod 400. The connector 420 is rotatably connected to the docking portion 212, and the locking member 440 is rotatably provided on one end of the connector 420 close to the hinge base 210. The locking member 440 is provided with a handle 441 and a barb 442. The torsion spring 430 abuts against the locking member 440, and the torsion spring 430 provides elastic force to drive the barb 442 to maintain abutment with the docking portion 212.

[0062] The docking portion 212 is provided with an avoidance groove 11, a limiting inclined surface 12 and a stopping hook 13. The avoidance groove 11 is located on the side of the docking portion 212 close to the lamp holder 100. The stopping hook 13 is located at the junction of the avoidance groove 11 and the limiting inclined surface 12, and the stopping hook 13 is arranged in a direction away from the lamp holder 100.

[0063] The limiting slope 12 serves as a rotation limit of the connecting head 420 and is used to limit the unfolding range of the tripod 400. Specifically, during the unfolding of the tripod 400, the connecting head 420 continuously approaches the limiting slope 12 until the connecting head 420 abuts against the limiting slope 12.

[0064] When the stand 400 switches between different states, the matching state between the locking member 440 and the docking portion 212 is as follows:

[0065] The tripod 400 is in a retracted state (eg Fig. 9 ) to the expanded state (as shown Figure 6 During the process as shown in the figure, the barb 442 on the locking member 440 slides from the avoidance groove 11 on the docking portion 212 to the stop hook 13 under the elastic force provided by the torsion spring 430. When the barb 442 leaves the stop hook 13, the locking member 440 rotates toward the side close to the docking portion 212 under the action of the torsion spring 430. In this state, the barb 442 approaches the limiting inclined surface 12 until the handle 441 abuts against the stop hook 13, and the barb 442 enters directly below the stop hook 13 (as shown in the figure). Figure 7As shown), the tripod 400 is rotated in the opposite direction, the barb 442 is engaged with the stop hook 13, and the stop hook 13 blocks the barb 442 from moving from the limiting inclined surface 12 side to the side where the avoidance groove 11 is located, thereby keeping the tripod 400 in the unfolded state, as shown. Figure 6 As shown, the portable lift work light 10 is prevented from tipping over.

[0066] See also Figure 7 When the tripod 400 is switched from the unfolded state to the retracted state, the tripod 400 is first moved in a direction away from the telescopic rod 200 so that the barb 442 is separated from the stop hook 13;

[0067] See also Figure 8 Then, the handle 441 is moved to flip the locking member 440 toward the side away from the docking portion 212, and the barb 442 leaves the bottom of the stop hook 13. The handle 441 is pressed continuously, and the tripod 400 is moved at the same time to rotate the tripod 400 toward the direction close to the telescopic rod 200.

[0068] See also Fig. 9 When the tripod 400 is close to the telescopic rod 200, the connector 420 rises relative to the docking portion 212, and the barb 442 moves from the limiting inclined surface 12 side to the avoidance groove 11 side. When the barb 442 moves to the top of the stop hook 13, the handle 441 is released, and the locking member 440 is flipped toward the docking portion 212 side under the elastic force of the torsion spring 430, so that the barb 442 is embedded in the avoidance groove 11;

[0069] See also Figure 2 , continue to move the tripod 400 until the tripod 400 is engaged with the buckle 231 on the retaining ring 230, and the tripod 400 is switched from the extended state to the retracted state.

[0070] Furthermore, in the portable lifting work lamp 10, the chassis composed of the hinge seat 210 and the multiple legs 400 provides support, and the center position of the hinge seat 210 is the force point of the lamp head 100 and the telescopic rod 200. Figure 1As shown, the portable lifting work lamp 10 is an overall slender structure with a high center of gravity. The portable lifting work lamp 10 is used in an outdoor environment. When it needs to be used in a windy environment, due to its high center of gravity, the portable lifting work lamp 10 is easily blown down by the wind. In addition, since the battery pack 330 that provides electrical energy is separated from the portable lifting work lamp 10 body and is externally placed in the portable electrical appliance box 300 in the present invention, while reducing the weight of the portable lifting work lamp 10 body, it also makes the portable lifting work lamp 10 more likely to be blown down. Moreover, the reduction in the mass of the portable lifting work lamp 10 body also makes it easy for it to deviate from its original position under the influence of vibration when working in an environment with strong vibration. In this way, in a strong wind, When used in an environment with large vibration, it is necessary to set a heavy object on the tripod 400 to fix it, that is, the structure in which the battery pack 330 and the lamp head 100 are separately arranged causes the portable lifting work lamp 10 to have a weak anti-dumping ability; in addition, in the present invention, the portable electrical box 300 and the work lamp body are designed separately, and the two are connected by a spare cable. When someone passes by the work lamp body and the portable electrical box 300 or needs to move the portable lifting work lamp 10, it is easy to pull the spare cable, causing the spare cable to fall off the electrical socket 311 or the electrical connector 211, and even cause damage to the electrical socket 311 and the electrical connector 211. In order to solve the above problems, the portable lifting work lamp 10 also includes a sensing module 600.

[0071] See also Fig.13 , the sensing module 600 includes a transfer seat 610 and a sensing switch 620 , the transfer seat 610 is disposed at the bottom of the hinge seat 210 , and a magnet 611 is disposed in the transfer seat 610 ;

[0072] See also Fig.11 , a plurality of docking buckles 612 are arranged on the adapter 610, and a card slot 21 matching the docking buckles 612 is opened at the bottom of the storage box 314, and the card slot 21 includes a limiting portion 21a and an avoiding portion 21b, and the limiting portion 21a is connected to the avoiding portion 21b, wherein the width of the avoiding portion 21b on the card slot 21 is greater than the width of the docking buckle 612, and the docking buckle 612 can extend into or leave the card slot 21 through the avoiding portion 21b, and the width of the upper limiting portion 21a of the card slot 21 is less than the width of the docking buckle 612, that is, when the docking buckle 612 is in the limiting portion 21a, it cannot leave the card slot 21; when the adapter 610 rotates relative to the storage box 314, the docking buckle 612 moves from the avoiding portion 21b of the card slot 21 to the limiting portion 21a (or from the limiting portion 21a to the avoiding portion 21b).

[0073] See also Fig.13The induction switch 620 is accommodated in the storage box 314. The induction switch 620 includes a protection box 621, a spring piece 622, a magnetic block 623 and a docking piece 624. The docking piece 624 and the spring piece 622 are respectively arranged at both ends of the protection box 621. The spring piece 622 is connected to the wiring block 320, and the docking piece 624 is connected to the battery pack 330. The spring piece 622 and the docking piece 624 are both provided with docking terminals 630. A gap is provided between the two docking terminals 630, that is, the two docking terminals 630 are separated from each other in the initial state. In this state, the induction switch 620 is in an untriggered state, and the circuit between the battery pack 330 and the wiring block 320 is open. Even if the induction switch 620 is in an untriggered state, the battery pack 330 and the wiring block 320 are in an open circuit. Even if the electrical connector 211 and the electrical socket 311 are connected with a spare cable, the lamp holder 100 cannot be lit. The magnetic block 623 is arranged on the spring piece 622, and the magnetic block 623 is arranged toward the magnet 611. When the magnetic block 623 moves into the range of influence of the magnetic field of the magnet 611, the magnetic block 623 bends the spring piece 622 toward the magnet 611 under the action of the magnetic attraction of the magnet 611, thereby making the two docking terminals 630 fit together. When the docking terminals 630 fit together, the spring piece 622 is connected to the docking piece 624. When the spring piece 622 and the docking piece 624 are connected, the induction switch 620 is triggered, and the battery pack 330 is connected to the terminal block 320.

[0074] The working principle of the sensing module 600 is introduced below:

[0075] When the tripod 400 is in the retracted state (eg Figure 2 As shown), hold the handle 240 to lift the main body of the work lamp composed of the lamp head 100, the telescopic rod 200 and the tripod 400, and turn over the portable electrical box 300 so that the bottom of the storage box 314 faces upward;

[0076] Align the docking buckle 612 on the adapter 610 with the avoidance portion 21b of the card slot 21, and place the main body of the working lamp consisting of the lamp head 100, the telescopic rod 200 and the tripod 400 on the portable electrical box 300. At this time, the docking buckle 612 passes through the avoidance portion 21b and enters the card slot 21. Fig.12 As shown;

[0077] Since the adapter 610 is now attached to the storage box 314, the magnetic block 623 on the storage box 314 enters the adsorption range of the magnet 611 on the adapter 610. Under the magnetic attraction of the magnet 611, the magnetic block 623 bends the spring piece 622 toward the magnet 611, thereby making the two docking terminals 630 attached to each other. When the docking terminals 630 are attached to each other, the spring piece 622 and the docking piece 624 are connected, and the induction switch 620 is activated.

[0078] Next, the portable electrical box 300 (or the main body of the working lamp composed of the lamp head 100, the telescopic rod 200 and the tripod 400) is rotated, and when the adapter 610 is rotated relative to the storage box 314, the docking buckle 612 slides from the avoiding portion 21b to the limiting portion 21a (such as Fig.11 As shown), the portable electrical appliance box 300 is rotated to connect with the hinge base 210.

[0079] After the portable lifting work light 10 is used, the portable electrical box 300 only needs to be rotated in the opposite direction so that the docking buckle 612 slides from the limiting portion 21a to the avoiding portion 21b, and the portable electrical box 300 can be separated from the adapter 610. At the same time, the magnetic block 623 leaves the adsorption range of the magnet 611, the spring 622 returns to its original state, the two docking terminals 630 are separated, and the battery pack 330 and the wiring board 320 are open again.

[0080] See also Fig.10 In this way, the portable electrical box 300 is fixed to the main body of the work lamp composed of the lamp head 100, the telescopic rod 200 and the tripod 400 through the adapter 610, which increases the weight of the portable lift work lamp 10, and by hanging the portable electrical box 300 on the hinge seat 210, the center of gravity of the portable lift work lamp 10 is moved downward, thereby improving the anti-dumping ability of the portable lift work lamp 10.

[0081] And the induction switch 620 is only activated when the portable electrical box 300 is mounted on the hinge seat 210, connecting the battery pack 330 with the terminal block 320, ensuring that the lamp head 100 can be lit only when the portable lifting work lamp 10 is in a fully assembled state, ensuring that the portable lifting work lamp 10 works in a safe state, and improving the safety performance of the portable lifting work lamp 10.

[0082] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
