The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] The present invention provides a portable lighting fixture 10 suitable for rail operations, aiming to improve the mobility and portability of emergency and maintenance type lighting fixtures, especially for rail operation scenarios, to meet the user's needs for labor-saving and quick movement of the lighting fixture.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the portable lighting fixture 10 comprises: a light box body 100, a lamp holder body 200, a telescopic rod 300 and a connection and matching device 400. The telescopic rod 300 is connected to the light box body 100, the lamp holder body 200 is arranged on the telescopic rod 300, and the light box body 100 and the lamp holder body 200 are electrically connected through a wire 101. The connection and matching device 400 is used to match with the external rail 20 (such as Figure 4 As shown in FIG. 4 , the connection fitting 400 includes a shaft fitting 410, and the shaft fitting 410 is used for pressing and contacting with the surface of the rail 20. Brackets 420 (as shown in FIG. 4 ) are provided at both ends of the shaft fitting 410. Figure 5 As shown), the bracket 420 can be detachably installed at the bottom of the light box body 100.

[0036] During actual use, since the area around the track is full of gravel, it is difficult for the user to move the lamp on the gravel-covered ground, so the present invention designs a connection and cooperation device 400. When it needs to be moved, the user sets up the portable lighting fixture 10 on the rail 20, and the rotating shaft accessory 410 at the bottom cooperates with the single rail 20 to achieve clamping, so that the portable lighting fixture 10 can be dragged and moved with the help of the rail 20. At the same time, after moving to the designated location, the portable lighting fixture 10 needs to be stably maintained at the current position, but since the rail 20 has a certain inclination, the portable lighting fixture 10 cannot stand stably on the rail 20 after the user lets go, and it may fall over, slide forward and backward. For this reason, the connection and cooperation device 400 of the present invention is also designed accordingly, so as to achieve the stability of the portable lighting fixture 10 after the user lets go.

[0037] Specifically, Figure 3 and Figure 5 As shown, in the present invention, the connection and matching device 400 also includes a deflection clamp 430 and a micro switch (not shown in the figure). The deflection clamp 430 is rotatably mounted on the bottom of the light box body 100, and the micro switch is arranged above the deflection clamp 430. When the deflection clamp 430 is pressed on the rail 20, the deflection clamp 430 will clamp the rail 20 and trigger the micro switch. At the same time, an electromagnetic coil (not shown in the figure) is wound inside the rotating shaft accessory 410. When the electromagnetic coil is energized, a magnetic attraction is generated to adsorb the rotating shaft accessory 410 on the rail 20; and a controller (not shown in the figure) is arranged inside the light box body 100, and the controller is electrically connected to the micro switch and the electromagnetic coil.

[0038] Preferably, Figure 5 As shown, the deflection clamp 430 includes: a hinge shaft 431, a top wall 432 and a clamp arm 433. The hinge shaft 431 is rotatably arranged at the bottom of the light box body 100. The top wall 432 presses or releases the rail 20. When the top wall 432 presses the rail 20, the clamp arm 433 presses the side wall of the rail 20. There are two deflection clamps 430, and the two deflection clamps 430 are symmetrically arranged about the symmetry axis of the cross section of the rail 20.

[0039] In this embodiment, if Figure 5 and Figure 6 As shown, cam blocks 411 are provided at both ends of the rotating shaft accessory 410 , and the cam blocks 411 and the top surface of the rail 20 are mutually clamped, so that the rotating shaft accessory 410 and the rail 20 are more closely matched.

[0040] In combination with the above structure, the working principle of the connection and matching device 400 of the present invention is explained below:

[0041] When it is necessary to move the portable lighting fixture 10 on the track, the user moves the portable lighting fixture 10 onto the track so that the rotating shaft accessory 410 and the rail 20 are mutually engaged (eg, Figure 6 and Figure 7 At this time, the shaft accessory 410 is pressed on the rail 20, and when the user drags it forward, as shown in FIG. Figure 8 As shown, the portable lighting fixture 10 is tilted relative to the rail 20 and relies on the shaft accessory 410 as a fulcrum for moving forward. The shaft accessory 410 functions as a roller. Moreover, the cam blocks 411 of the shaft accessory 410 abut against both sides of the top surface of the rail 20, which can make the shaft accessory 410 as stable as possible during the rolling process and will not be misaligned with the rail 20;

[0042] When the portable lighting fixture 10 stops moving (stationary state), the user no longer drags the portable lighting fixture 10, and the entire fixture is in a vertically erected state (eg, Figure 6 and Figure 7 As shown in the figure, the deflection clamp 430 will press on 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 lamp is erected as a whole, the deflection clamp 430 contacts the rail 20, and the rail 20 provides an upward support force to the top wall 432 of the deflection clamp 430, so that the deflection clamp 430 deflects around the connecting shaft 431, and then the clamp arms 433 of the two deflection clamps 430 will cooperate to clamp the side walls of the rail 20. In this way, relying on the gravity of the lamp itself, the deflection clamp 430 can clamp the rail 20, thereby increasing the friction and preventing the lamp from tipping over from the rail 20;

[0043] At the same time, after the deflection, the top wall 432 of the deflection clamp 430 will trigger the micro switch, and the micro switch will send a signal to the controller, so that the controller can know that the portable lighting fixture 10 needs to be in a stable placement state. In this case, the controller supplies power to the electromagnetic coil inside the rotating shaft accessory 410, so that it generates a magnetic attraction force, and then adsorbs on the rail 20, thereby further improving the stability of the portable lighting fixture 10 and the rail 20. In other words, the connection and matching device 400 increases the friction between the lighting fixture 10 and the rail, and also provides a magnetic attraction force, so that even if the rail 20 has a slight tilt angle, the lighting fixture 10 can still remain stable at the current position of the rail 20, and is not prone to sliding back and forth or tipping left and right;

[0044] When the portable lighting fixture 10 is to be moved again, the user only needs to use the rotating shaft accessory 410 as a fulcrum to deflect and tilt the portable lighting fixture 10 to a certain angle (such as Figure 8As shown in FIG. 1 , the deflection clamp 430 can be separated from the rail 20. At this time, the micro switch is reset, 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 connection and cooperation device 400 of the present invention restricts the lighting fixture 10 in a stationary state in multiple directions according to actual application scenarios. Specifically, since the rail 20 may have an inclination angle in the extension direction, the connection and cooperation device 400 needs to limit the sliding of the lighting fixture 10 in the front-to-back direction; at the same time, the connection and cooperation device 400 also needs to prevent the lighting fixture 10 from tilting in the left-to-right direction of the rail 20. Therefore, the connection and cooperation device 400 is designed with a rotating shaft accessory 410 and a deflection clamp 430. When the connection and cooperation device 400 is matched with the rail 20, the rotating shaft accessory 410 will generate a magnetic attraction to absorb the rail 20, thereby preventing sliding or tipping; the deflection clamp 430 will clamp the rail 20, thereby increasing the friction force and overcoming the torque of left-to-right tipping.

[0046] It is worth noting that the connection and cooperation device 400 of the present invention does not require the user to operate deliberately, that is, the connection and cooperation device 400 can switch modes autonomously according to the use status of the lighting fixture 10. For example, when the user drags the lighting fixture 10, the entire lighting fixture is tilted relative to the rail 20, the deflection clamp 430 naturally moves away from the rail 20, and the micro switch will not be triggered; when the lighting fixture 10 is stationary, the lighting fixture 10 stands upright on the rail 20, and the gravity of the lighting fixture itself will cause the deflection clamp 430 to clamp the rail 20 and trigger the micro switch, so that the shaft accessory 410 will generate a magnetic attraction to adsorb the rail 20; when the lighting fixture 10 is dragged again, the drag 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 separate from the rail 20, and the magnetic attraction of the shaft accessory 410 disappears.

[0047] In this embodiment, if Figure 3 and Figure 4 As shown, the light box body 100 includes: a shell 110, a speaker 120, a battery pack (not shown), a display screen 130 and a touch switch 140, the telescopic pull rod 300 is connected to the shell 110, the speaker 120 and the battery pack are accommodated in the interior of the shell 110, the display screen 130 and the touch switch 140 are arranged on the surface of the shell 110, and the controller is electrically connected to the speaker 120, the battery pack, the display screen 130 and the touch switch 140.

[0048] During use, the user inputs instructions to the controller by touching the switch 140 to adjust the lighting mode of the lamp body 200. At the same time, the portable lighting fixture 10 is provided with a voice broadcast function. When visibility is low, the user can choose to enable the voice broadcast function, so that each operation of the touch switch 140 will get good feedback.

[0049] Preferably, Figure 3 As shown, the bottom of the housing 110 is also provided with a roller 111 and a support leg 112, the roller 111 is mounted on the housing 110 through a wheel frame 113, and the support leg 112 is fixedly connected to the housing 110 through bolts. The setting of the roller 111 can facilitate the portable lighting fixture 10 to be dragged and moved on the ground (not the rail 20), and the setting of the support leg 112 is convenient to cooperate with the roller 111 to realize the portable lighting fixture 10 standing upright on the ground.

[0050] In this embodiment, if Figure 1 and Figure 2 As shown, the lamp holder body 200 includes: a lampshade 210, a lens 220 and a light-emitting board (not shown), the light-emitting board is installed in the lampshade 210, and the lens 220 is covered on the light-emitting board and fixedly connected to the lampshade 210. When in use, the light box body 100 supplies power to the light-emitting board, and the light generated by the light-emitting board is irradiated to the outside through the lens 220. The heat generated by the light-emitting board will be transferred to the lampshade 210, and then dissipated into the air by the lampshade 210. Furthermore, a plurality of heat dissipation fins 211 are provided on the surface of the lampshade 210, and the heat dissipation fins 211 can greatly increase the effective heat dissipation area in contact with the air, thereby enhancing the heat dissipation performance.

[0051] Preferably, Figure 3 As shown, positioning sleeve assemblies 230 are further provided on both sides of the lamp holder body 200, and the positioning sleeve assemblies 230 are hinged to the lampshade 210, and the positioning sleeve assemblies 230 are sleeved on the telescopic pull rod 300. In this way, the lamp holder body 200 can be conveniently installed on the telescopic pull rod 300 through the positioning sleeve assemblies 230, and the hinge between the lamp holder body 200 and the telescopic pull rod 300 is realized, so that the user can adjust the illumination angle of the lamp holder body 200 conveniently.

[0052] In summary, the portable lighting fixture 10 suitable for railroad operations of the present invention can be stably and conveniently mounted on the rails 20, thereby improving mobility and portability, and meeting the user's needs for labor-saving and quick movement of the lighting fixture.

[0053] 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.
