Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and in particular to a liftable work light with adjustable lighting direction. Background Technology

[0002] Lifting work lights are used in emergency rescue and relief work, primarily to solve the problem of insufficient lighting during emergency rescue and repair work. Existing lifting work lights are fixedly mounted on a lifting mast, and the illumination range can only be changed by adjusting the height and rotation angle of the mast. For example, when more distant areas need illumination, the height of the mast needs to be increased; when side illumination is needed, the angle of the mast needs to be rotated.

[0003] However, in this existing method of raising work lights, all the lights on them face the same direction. This means that when the work light is illuminating the front, it cannot simultaneously illuminate the rear or sides, thus limiting the direction of illumination. Moreover, the existing method requires adjusting the raising rod to change the direction of the lights, which is rather cumbersome.

[0004] Therefore, how to design an adjustable lifting work light that allows for convenient adjustment of the lighting direction, and allows multiple lights to operate independently, providing simultaneous illumination in multiple directions and expanding the lighting range during work, is a technical problem that needs to be solved by technicians in this field. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a lifting work light with adjustable lighting direction, which enables convenient adjustment of the lighting direction of the lamp, and multiple lamps can be independent of each other, so as to illuminate multiple directions at the same time and expand the lighting range during work.

Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. 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.

[0038] The present invention provides a lifting work light 10 with adjustable illumination direction, such as... Figure 1 As shown, it includes: a movable vehicle body 100, a foldable lifting rod assembly 200, and a lamp head component 300 disposed at the top of the lifting rod assembly 200. The movable vehicle body 100 is provided with a clamp hinge 110, and the lifting rod assembly 200 is rotatably mounted on the movable vehicle body 100 through the clamp hinge 110.

[0039] The lifting rod assembly 200 includes an outer fixing rod 210 and an inner telescopic rod 220 (e.g., Figure 8 As shown, the inner telescopic rod 220 is slidably disposed within the outer fixing rod 210. The lifting rod assembly 200 of the present invention changes the overall length of the lifting rod assembly 200 by changing the position of the inner telescopic rod 220 and the outer fixing rod 210, thereby realizing the height adjustment of the lamp head component 300.

[0040] like Figure 2 and Figure 4As shown, the lamp holder component 300 includes a support frame 310, a clamping connector 320, and multiple lamp components 330. The support frame 310 is connected to the top end of the inner lining telescopic rod 220 via the clamping connector 320, and the multiple lamp components 330 are movably mounted on the support frame 310. Preferably, the clamping connector 320 is detachably connected to the inner lining telescopic rod 220. When in use, the clamping connector 320 can clamp and fix the inner lining telescopic rod 220 by means of bolts or eccentric wheels. When not in use, loosening the bolts or rotating the eccentric wheel will allow the clamping connector 320 to no longer clamp the inner lining telescopic rod 220, thereby disassembling the lamp holder component 300.

[0041] In this invention, such as Figure 3 and Figure 4 As shown, the lighting assembly 330 includes a lighting body 331, a bracket 332, and an adjusting bolt 333. The lighting body 331 is mounted on the bracket 332, and the bracket 332 is rotatably mounted on the support frame 310 via the adjusting bolt 333. In this embodiment, the bracket 332 has a U-shaped structure, the lighting body 331 is rotatably mounted on the bracket 332, and the bracket 332 has a waist-shaped groove 334. The lighting body 331 has a limiting screw 335 that mates with the waist-shaped groove 334. The waist-shaped groove 334 and the limiting screw 335 mate, allowing the lighting body 331 to tilt or pitch relative to the bracket 332, and the tilt angle between the two is adjustable.

[0042] In use, the operator moves the adjustable-direction lifting work light 10 to a suitable location, and then rotates the lifting rod assembly 200 to bring it from its folded state (e.g., Figure 6 (As shown) changes to a vertical state (such as) Figure 1 (As shown), then opening the lamp body 331 will provide illumination. During use, if simultaneous illumination in different directions is desired, such as illuminating both the left and right sides, the operator first loosens the adjusting bolt 333, then rotates one lamp body 331 and its bracket 332 90 degrees, and then rotates the other lamp body 331 and its bracket 332 in the opposite direction by 90 degrees. After adjustment, the operator retightens the adjusting bolt 333 to fix the bracket 332. At this point, the structure of the lamp holder component 300 is... Figure 2 Become like Figure 5 As shown, the two lamp bodies 331 face the left and right sides respectively, and the lamp head component 300 can illuminate the left and right sides simultaneously.

[0043] It should be emphasized that in the lamp holder component 300 of the present invention, each lamp assembly 330 is relatively independent. In this way, the lighting direction of multiple lamp assemblies 330 can be independently adjusted according to actual needs, thereby achieving simultaneous lighting from multiple directions. Moreover, in the present invention, adjusting the lighting direction of the lamp body 331 only requires turning the adjusting bolt 333, which is simple to operate and can achieve quick and convenient operation.

[0044] In this embodiment, the end of the outer casing fixing rod 210 is provided with a locking pin 211, and the movable vehicle body 100 is provided with a buckle structure 120 that cooperates with the locking pin 211 (e.g., Figure 6 (As shown). When the lifting rod assembly 200 changes from a folded state to a vertical state, the locking pin 211 at the end of the outer fixing rod 210 will approach and press against the buckle structure 120. The buckle structure 120 and the locking pin 211 engage with each other, thereby fixing the outer fixing rod 210 through the locking pin 211, so that the lifting rod assembly 200 is stably kept in a vertical state. When the lifting rod assembly 200 needs to be folded again, the operator only needs to open the buckle structure 120 to disengage the locking pin 211 from the buckle structure 120, and the lifting rod assembly 200 can then rotate back to the folded state.

[0045] When not in use, the lifting rod assembly 200 is in a folded state. However, since the clamp hinge 110 is only connected to the outer fixing rod 210 of the lifting rod assembly 200, it can only restrict the outer fixing rod 210 and cannot limit the inner telescopic rod 220. The inner telescopic rod 220 can rotate along the axis of the outer fixing rod 210. This causes the inner telescopic rod 220 and the lamp holder component 300 on it to easily deflect and swing along their central axis when shaken, increasing the possibility of collisions during transportation and posing a safety hazard. To solve this technical problem, the present invention has made a special design.

[0046] Specifically, such as Figure 7 and Figure 8 As shown, the mobile vehicle body 100 is equipped with a rotation-limiting locking assembly 130, which includes a top holding rod 131, a limiting guide seat 132, and a locking block 133. The mobile vehicle body 100 has a receiving groove 101 that mates with the top holding rod 131. The top holding rod 131 is slidably disposed within the receiving groove 101, and a telescopic elastic member 102 is provided within the receiving groove 101. The two ends of the telescopic elastic member 102 are respectively connected to the bottom of the top holding rod 131 and the receiving groove 101. The limiting guide seat 132 is disposed on the outer outer fixing rod 210, and the top holding rod 131 passes through the limiting guide seat 132. The locking block 133 is movably disposed between the outer outer fixing rod 210 and the inner lining telescopic rod 220, and the locking block 133 is connected to the end of the top holding rod 131. The inner lining telescopic rod 220 has a clearance groove 221, and the locking block 133 enters or disengages from the clearance groove 221.

[0047] For example, when the lifting rod assembly 200 is folded, the telescopic elastic element 102 is compressed, and the top holding rod 131 tends to push the locking block 133 towards the inner lining telescopic rod 220, causing the locking block 133 to enter the clearance groove 221. When the lifting rod assembly 200 is vertical, the telescopic elastic element 102 is stretched, and the top holding rod 131 tends to pull the locking block 133 away from the inner lining telescopic rod 220, causing the locking block 133 to disengage from the clearance groove 221. The specific working principle will be explained below.

[0048] Preferred, such as Figure 9 As shown, the bottom of the clearance groove 221 is provided with a locking tooth 221a, and the locking block 133 is provided with a limiting tooth 133a. When the locking block 133 enters the clearance groove 221, the limiting tooth 133a and the locking tooth 221a mesh with each other to prevent the inner lining telescopic rod 220 from rotating along the axis.

[0049] Furthermore, in this embodiment, as Figure 6 and Figure 10 As shown, the mobile vehicle body 100 is equipped with an auxiliary clamp assembly 140. The auxiliary clamp assembly 140 includes a clamp seat 141 and a clamp cover 142. The clamp seat 141 is fixed to the mobile vehicle body 100. One end of the clamp cover 142 is hinged to the clamp seat 141, and the other end of the clamp cover 142 is magnetically detachably connected to the clamp seat 141. When the lifting rod assembly 200 is folded into place, the outer fixing rod 210 presses against the clamp seat 141, and the clamp cover 142 can close, that is, the lifting rod assembly 200 is exactly between the clamp seat 141 and the clamp cover 142.

[0050] The working principle of the rotation-limiting locking assembly 130 will be explained below, taking into account the specific structure described above:

[0051] When the lifting rod assembly 200 is folded, firstly, the operator needs to retract the inner telescopic rod 220 into the outer fixing rod 210. After the inner telescopic rod 220 is retracted to its final position, the clearance groove 221 on the inner telescopic rod 220 will correspond exactly to the position of the locking block 133. Next, the operator folds the lifting rod assembly 200. At this time, the locking block 133 will enter the clearance groove 221, and the inner telescopic rod 220 will push the top holding rod 131 to move together through the locking block 133. The top holding rod 131 will insert into the depth of the receiving groove 101, and the telescopic elastic element 102 will be compressed. After folding, the lifting rod assembly 200 is placed horizontally and is secured by the auxiliary clamp assembly 140. The compressed telescopic elastic element 102 provides support to the top holding rod 131, which pushes the locking block 133 against the receiving groove 101. The limiting tooth 133a of the locking block 133 meshes with the locking tooth 221a of the receiving groove 101, thereby preventing the inner lining telescopic rod 220 from rotating along the central axis and ensuring the stability of the inner lining telescopic rod 220 after folding.

[0052] When the lifting rod assembly 200 is vertical, the operator rotates the lifting rod assembly 200, and the top holding rod 131 no longer abuts against the telescopic elastic element 102, releasing the elastic potential energy of the telescopic elastic element 102; furthermore, as the top holding rod 131 slides, the telescopic elastic element 102 is stretched, and the tension on the top holding rod 131 causes the locking block 133 to disengage from the receiving groove 101 (e.g., Figure 8 As shown in the figure, the inner lining telescopic rod 220 is no longer restricted and can be raised and rotated freely.

[0053] It should be noted that when the lifting rod assembly 200 is folded, the locking block 133 cooperates with the clearance groove 221, which not only prevents the axial movement of the inner lining telescopic rod 220, making it impossible for the folded inner lining telescopic rod 220 to be stretched, but also prevents the inner lining telescopic rod 220 from rotating along the central axis.

[0054] Furthermore, during the verticalization of the lifting rod assembly 200, the telescopic elastic element 102 first changes from a compressed state to a free state, and the top holding rod 131 first provides a pushing force to the locking block 133, which is positioned within the receiving groove 101 to prevent the inner lining telescopic rod 220 from moving. After the lifting rod assembly 200 rotates a certain angle, the telescopic elastic element 102 changes from a free state to a stretched state, and the top holding rod 131 provides a pulling force to the locking block 133, causing the locking block 133 to retract from the receiving groove 101. At this point, the inner lining telescopic rod 220 can move. In this way, when the lifting rod assembly 200 is at a lower angle, the inner lining telescopic rod 220 cannot move, thus ensuring that the inner lining telescopic rod 220 remains stable during mode switching.

[0055] It is important to emphasize that during folding, the position of the clearance groove 221 will only correspond precisely to the position of the locking block 133 when the inner lining telescopic rod 220 is fully retracted. Only then can the locking block 133 enter the clearance groove 221 during folding, allowing the lifting rod assembly 200 to be placed horizontally. If the inner lining telescopic rod 220 is not fully retracted, the locking block 133 will abut against the side wall of the inner lining telescopic rod 220 during folding. In this case, even if the telescopic elastic element 102 is compressed to its limit, the top holding rod 131 will still block the lifting rod assembly 200 due to insufficient travel, thus preventing the lifting rod assembly 200 from being placed horizontally (e.g., ...). Figure 11 As shown), the clamp cover 142 cannot be fastened onto the clamp seat 141. This design serves as a reminder to staff that the inner telescopic rod 220 has not fully retracted.

[0056] To further enhance the alerting function, the auxiliary clamp assembly 140 includes an alarm module (not shown). When the lifting rod assembly 200 fails to fold into place, the clamp cover 142 cannot fully engage with the clamp seat 141, meaning the clamp cover 142 cannot magnetically connect with the clamp seat 141. In this case, the alarm module will sound an alarm as a warning. In actual use, the alarm module can be a speaker to provide audible alerts; alternatively, it can be a warning light that flashes to serve as a warning.

[0057] In one embodiment, such as Figure 6 As shown, the mobile vehicle body 100 is equipped with universal casters 103, which makes it convenient for staff to push the adjustable lighting direction lifting work light 10 forward, thus improving the portability of the lifting work light 10.

[0058] In summary, the adjustable lighting direction lifting work light 10 of the present invention can conveniently adjust the lighting direction of the lamp, and the multiple lamp components 330 are independent of each other, which can illuminate multiple directions simultaneously, thus expanding the lighting range during work.

[0059] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
