Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, and in particular to a portable lighting fixture suitable for track work. Background Technology

[0002] Work lights can be used in outdoor temporary lighting scenarios such as disaster relief and rescue. To meet the needs of outdoor lighting, work lights should be portable, have a wide lighting range, and be stable in operation. The locations where disaster relief and rescue missions are carried out are often inconvenient to access, requiring users to carry the work lights to the destination. The process of carrying them consumes the user's physical strength, which in turn affects the efficiency of carrying out disaster relief and rescue missions.

[0003] Chinese invention patent CN117906111B, entitled "A Luggage-Type Lighting Lamp," discloses a lighting fixture comprising a light box, a lamp head, a telescopic rod, and an unfolding mechanism. The unfolding mechanism includes a base, a sliding bracket, and a balance arm. Wheels are provided on the sliding bracket. Users can tilt the light box by holding the telescopic rod, thus propelling the luggage-type lighting lamp forward and making the carrying process easier.

[0004] However, when used in track operation scenarios, the existing lighting fixtures are difficult to move on the gravel around the rails, and the problem of inconvenient movement of the fixtures still exists.

[0005] Therefore, how to design a portable lighting fixture suitable for track work, which can be stably and conveniently installed on the rails to improve mobility and portability, and meet the user's need for labor-saving and quick movement of the lighting fixture, is a technical problem that technicians in this field need to solve.

[0034] This invention provides a portable lighting fixture 10 suitable for track work, which aims to improve the mobility and portability of emergency rescue and maintenance lighting fixtures, especially for track work scenarios, to meet the user's need for labor-saving and quick movement of lighting fixtures.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the portable lighting fixture 10 includes: a lamp housing body 100, a lamp head body 200, a telescopic rod 300, and a connecting device 400. The telescopic rod 300 is connected to the lamp housing body 100, and the lamp head body 200 is mounted on the telescopic rod 300. The lamp housing body 100 and the lamp head body 200 are electrically connected via a wire 101. The connecting device 400 is used to connect with an external rail 20 (e.g., a railway track 20). Figure 4 As shown), the connecting and mating device 400 includes a rotating shaft fitting 410, which is used for pressing and contacting the surface of the rail 20. The rotating shaft fitting 410 has brackets 420 at both ends (e.g., ...). Figure 5 As shown, bracket 420 is detachably installed at the bottom of light box body 100.

[0036] In practical use, due to the gravel surrounding the track, it is difficult for users to move the lamp on the gravelly ground. Therefore, this invention designs a connecting and engaging device 400. When movement is needed, the user mounts the portable lighting fixture 10 on the rail 20, and the pivot fitting 410 at its bottom engages with a single rail 20 to achieve a locking mechanism, thus allowing the portable lighting fixture 10 to be dragged along the rail 20. Simultaneously, after reaching the designated location, the portable lighting fixture 10 needs to remain stably in its current position. However, due to the slight inclination of the rail 20, the portable lighting fixture 10 may not remain stably upright on the rail 20 after the user releases its grip, potentially tipping over or sliding forward or backward. Therefore, the connecting and engaging device 400 of this invention is also designed accordingly to ensure the stability of the portable lighting fixture 10 after the user releases its grip.

[0037] Specifically, such as Figure 3 and Figure 5 As shown, in this invention, the connecting and mating device 400 further includes a deflection clamping member 430 and a micro switch (not shown). The deflection clamping member 430 is rotatably mounted on the bottom of the light box body 100, and the micro switch is located above the deflection clamping member 430. When the deflection clamping member 430 presses against the rail 20, it clamps the rail 20 and triggers the micro switch. Simultaneously, an electromagnetic coil (not shown) is wound inside the rotating shaft accessory 410. When the electromagnetic coil is energized, it generates a magnetic attraction force that attracts the rotating shaft accessory 410 to the rail 20. Furthermore, a controller (not shown) is provided inside the light box body 100, and the controller is electrically connected to the micro switch and the electromagnetic coil.

[0038] Preferred, such as Figure 5 As shown, the deflection clamping member 430 includes: a hinge shaft 431, a top wall 432, and a clamping arm 433. The hinge shaft 431 is rotatably mounted on the bottom of the light box body 100. The top wall 432 presses against or disengages from the rail 20. When the top wall 432 presses against the rail 20, the clamping arm 433 presses against the side wall of the rail 20. There are two deflection clamping members 430, and the two deflection clamping members 430 are symmetrically arranged about the axis of symmetry of the cross-section of the rail 20.

[0039] In this embodiment, as Figure 5 and Figure 6 As shown, the two ends of the rotating shaft accessory 410 are provided with cam blocks 411. The cam blocks 411 are engaged with the top surface of the rail 20, making the fit between the rotating shaft accessory 410 and the rail 20 tighter.

[0040] The working principle of the connection and mating device 400 of the present invention will be explained below in conjunction with the above structure:

[0041] When it is necessary to move the device on the track, the user moves the portable lighting fixture 10 onto the track, causing the pivot fitting 410 to engage with the rail 20 (e.g., Figure 6 and Figure 7 (As shown). At this time, the rotating shaft accessory 410 is pressed against the rail 20. When the user drags it forward, as shown... Figure 8 As shown, the portable lighting fixture 10 is tilted relative to the rail 20 and relies on the pivot fitting 410 as a fulcrum for movement. The pivot fitting 410 functions like a roller. Moreover, the cam blocks 411 of the pivot fitting 410 abut against both sides of the top surface of the rail 20, which allows the pivot fitting 410 to remain as stable as possible during rolling and to prevent it from misaligning with the rail 20.

[0042] When the movement stops (stationary state), the user no longer drags the portable lighting fixture 10, and the entire fixture is in an upright position (e.g., Figure 6 and Figure 7 As shown, at this time, the deflecting clamp 430 will press against the rail 20 and clamp the rail 20 to increase the friction between the light box body 100 and the rail 20. Specifically, as the light fixture is erected, the deflecting clamp 430 contacts the rail 20, and the rail 20 provides an upward support force to the top wall 432 of the deflecting clamp 430, causing the deflecting clamp 430 to deflect around the connecting shaft 431. Then, the clamping arms 433 of the two deflecting clamps 430 will cooperate to clamp the side wall of the rail 20. In this way, relying on the weight of the light fixture itself, the deflecting clamp 430 can clamp the rail 20, thereby increasing the friction and preventing the light fixture from tipping over the rail 20.

[0043] Meanwhile, the top wall 432 of the deflected clamp 430 triggers a microswitch, which sends a signal to the controller. The controller then knows that the portable lighting fixture 10 needs to be in a stable position. In this case, the controller powers the electromagnetic coil inside the rotating shaft accessory 410, causing it to generate a magnetic force, which in turn attracts it to the rail 20, thereby further improving the stability of the portable lighting fixture 10 and the rail 20. In other words, the connecting and mating device 400 increases the friction between the lighting fixture 10 and the rail and also provides magnetic attraction. Thus, even if the rail 20 has a slight tilt angle, the lighting fixture 10 can still remain stable in its current position on the rail 20 and is not prone to sliding back and forth or tilting left and right.

[0044] When the portable lighting fixture 10 needs to be moved again, the user only needs to use the pivot accessory 410 as a fulcrum and tilt the fixture 10 at a certain angle (e.g., ...). Figure 8As shown, this allows the deflection clamp 430 to disengage from the rail 20. At this point, the micro switch resets, the controller no longer supplies power to the electromagnetic coil, the magnetic attraction between the rotating shaft accessory 410 and the rail 20 disappears, and the lighting fixture 10 can slide smoothly along the rail 20.

[0045] It should be emphasized that the connecting and engaging device 400 of the present invention restricts the lighting fixture 10 in multiple directions for practical application scenarios. Specifically, since the rail 20 may have an inclination angle in its extension direction, the connecting and engaging device 400 needs to restrict the sliding of the lighting fixture 10 in the front-to-back direction; at the same time, the connecting and engaging device 400 also needs to prevent the lighting fixture 10 from tilting in the left-to-right direction of the rail 20. Therefore, the connecting and engaging device 400 is designed with a rotating shaft accessory 410 and a deflection clamping member 430. When the connecting and engaging device 400 engages with the rail 20, the rotating shaft accessory 410 generates a magnetic attraction to attract the rail 20, thereby preventing sliding or tilting; the deflection clamping member 430 clamps the rail 20, thereby increasing friction and overcoming the torque of left-to-right tilting.

[0046] It is worth noting that the connection and engagement device 400 of the present invention does not require special operation by the user; that is, the connection and engagement device 400 can automatically switch modes according to the usage status of the lighting fixture 10. For example, when the user drags the lighting fixture 10, the fixture is tilted relative to the rail 20, and the deflection clamp 430 naturally moves away from the rail 20, so the micro switch is not triggered. When the lighting fixture 10 is stationary, it stands upright on the rail 20, and its own weight causes the deflection clamp 430 to clamp the rail 20 and trigger the micro switch, causing the rotating shaft accessory 410 to generate a magnetic attraction to attract the rail 20. When the lighting fixture 10 is dragged again, the dragging force provided by the user will cause the lighting fixture 10 to tilt relative to the rail 20 again, thereby causing the deflection clamp 430 to disengage from the rail 20, and the magnetic attraction of the rotating shaft accessory 410 to disappear.

[0047] In this embodiment, as Figure 3 and Figure 4 As shown, the main body 100 of the light box includes: a housing 110, a speaker 120, a battery pack (not shown), a display screen 130, and a touch switch 140. The telescopic rod 300 is connected to the housing 110. The speaker 120 and the battery pack are housed inside the housing 110. The display screen 130 and the touch switch 140 are disposed on the surface of the housing 110. The controller is electrically connected to the speaker 120, the battery pack, the display screen 130, and the touch switch 140.

[0048] In use, the user inputs commands to the controller via the touch switch 140 to adjust the illumination mode of the lamp head 200. Simultaneously, the portable lighting fixture 10 is equipped with a voice broadcast function; when visibility is low, the user can choose to enable the voice broadcast function, ensuring good feedback every time the touch switch 140 is activated.

[0049] Preferred, such as Figure 3 As shown, the bottom of the housing 110 is also provided with rollers 111 and support legs 112. The rollers 111 are mounted on the housing 110 via wheel frames 113, and the support legs 112 are fixedly connected to the housing 110 by bolts. The rollers 111 facilitate the movement of the portable lighting fixture 10 on the ground (not the rail 20), and the support legs 112 facilitate the use of the rollers 111 to make the portable lighting fixture 10 stand upright on the ground.

[0050] In this embodiment, as Figure 1 and Figure 2 As shown, the lamp holder body 200 includes: a lampshade 210, a lens 220, and a light-emitting plate (not shown). The light-emitting plate is installed inside the lampshade 210, and the lens 220 covers the light-emitting plate and is fixedly connected to the lampshade 210. In use, the lamp box body 100 supplies power to the light-emitting plate. The light generated by the light-emitting plate shines into the outside through the lens 220. The heat generated by the light-emitting plate is transferred to the lampshade 210 and then dissipated into the air by the lampshade 210. Furthermore, the surface of the lampshade 210 is provided with several heat dissipation fins 211. The heat dissipation fins 211 can significantly increase the effective heat dissipation area in contact with the air, thereby enhancing the heat dissipation performance.

[0051] Preferred, such as Figure 3 As shown, positioning sleeve assemblies 230 are also provided on both sides of the lamp head body 200. The positioning sleeve assemblies 230 are hinged to the lamp cover 210 and are sleeved on the telescopic rod 300. In this way, the lamp head body 200 can be easily installed onto the telescopic rod 300 through the positioning sleeve assemblies 230, and the hinge between the lamp head body 200 and the telescopic rod 300 can be realized, thereby facilitating the user to adjust the illumination angle of the lamp head body 200.

[0052] In summary, the portable lighting fixture 10 of the present invention, suitable for track work, can be stably and conveniently installed on the rail 20, thereby improving mobility and portability and meeting the user's need for labor-saving and quick movement of the lighting fixture.

[0053] 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.
