[0034] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0036] As is understandable, portable lighting fixtures are mobile lighting devices composed of a light box, light tube, outriggers, and generator. Their lighting effect is better than traditional arc lamps and fluorescent lamps, and they are also more environmentally friendly. Portable lighting fixtures are suitable for various outdoor venues, such as stadiums, parking lots, construction sites, and traffic accident scenes, providing excellent illumination at night. For example, at construction sites, portable lighting fixtures can provide workers with ample light, ensuring construction quality and safety; in emergencies such as earthquakes and floods, portable lighting fixtures can provide timely and powerful lighting power to assist rescue personnel in their work; and in activities such as camping and outdoor adventure, they not only provide good lighting but also increase a sense of security and create a pleasant atmosphere.

[0037] However, existing portable lighting fixtures are prone to collapse during use. Once a fixture collapses, it not only affects its normal use but also the safety of the user.

[0038] Therefore, this utility model proposes a mobile lighting fixture anti-tipping support device 100, which aims to improve the problem that existing mobile lighting fixtures are prone to collapse during use.

[0039] Reference Figure 1 , Figure 2 and Figure 5 In one embodiment of this utility model, the mobile lighting fixture anti-tipping support device 100 includes:

[0040] First support structure 1a;

[0041] The second support mechanism 1b is detachably connected to the first support mechanism 1a;

[0042] The second support mechanism 1b and / or the first support mechanism 1a include a fixing component 11, a first support component 12 and a second support component 13. The fixing component 11 is used to connect the mobile lighting fixture. One end of the first support component 12 and the second support component 13 is rotatably disposed on the fixing component 11 to adjust the angle between the first support component 12 and the second support component 13. The other end of the first support component 12 and the second support component 13 is used to abut against the ground to support the mobile lighting fixture anti-tipping support device 100.

[0043] In this embodiment, the mobile lighting fixture anti-tipping support device 100 includes a first support mechanism 1a and a second support mechanism 1b, wherein the first support mechanism 1a can be detachably connected to the second support mechanism 1b. That is, when the mobile lighting fixture anti-tipping support device 100 of this embodiment is needed to support the mobile lighting fixture, the first support mechanism 1a and the second support mechanism 1b can be connected. With this design, the first support mechanism 1a serves as the left-side structure supporting the mobile lighting fixture, and the second support mechanism 1b serves as the right-side structure supporting the mobile lighting fixture, thus improving the overall installation stability of the mobile lighting fixture. When the mobile lighting fixture anti-tipping support device 100 of this embodiment is not needed to support the mobile lighting fixture, the first support mechanism 1a can be detached from the second support mechanism 1b, achieving separation of the first support mechanism 1a and the second support mechanism 1b. The separate structure facilitates the separate storage of the first support mechanism 1a and the second support mechanism 1b, making it convenient for manufacturers to sell and transport, and also convenient for users to handle and use.

[0044] At least one of the first support mechanism 1a and the second support mechanism 1b includes a fixing component 11, a first support component 12, and a second support component 13. As an example, the first support mechanism 1a and the second support mechanism 1b respectively include a fixing component 11, a first support component 12, and a second support component 13. The fixing component 11 is used to connect a portable lighting fixture to fix it onto the corresponding support mechanism. One end of the first support component 12 and the second support component 13 is rotatably mounted on the corresponding fixing component 11 to adjust the angle between the first support component 12 and the second support component 13. The other end of the first support component 12 and the second support component 13 is used to abut against the ground to support the portable lighting fixture anti-tipping support device 100 of this embodiment. It can be understood that when one end of the first support component 12 and the second support component 13 is supported on the ground, the other end of the first support component 12 and the second support component 13 can be translated and rotated relative to the fixing component 11 on a horizontal plane to change the relative angle between them. For ease of understanding, assume that the first support component 12 and the second support component 13 coincide in the vertical direction as the initial state. During the process of the first support component 12 rotating clockwise along the horizontal plane and the second support component 13 rotating counterclockwise along the horizontal plane, the relative angle between the first support component 12 and the second support component 13 increases from small to large, then decreases from large to small, and finally returns to the initial state. With this design, when the mobile lighting fixture anti-tipping support device 100 of this embodiment is needed to support the mobile lighting fixture, the first support component 12 and the second support component 13 can be rotated to increase the relative angle between them, thereby improving the installation stability of the mobile lighting fixture. Furthermore, the relative angle between the first support component 12 and the second support component 13 can be appropriately increased or decreased according to the lighting location of the mobile lighting fixture, so that the mobile lighting fixture anti-tipping support device 100 can be adapted and installed in the lighting location. When the mobile lighting fixture anti-tipping support device 100 of this embodiment is not needed to support the mobile lighting fixture, the first support component 12 and the second support component 13 can be rotated so that the first support component 12 and the second support component 13 coincide in the vertical direction. That is, the first support mechanism 1a and the second support mechanism 1b form an integrated structure by rotating and coinciding, thereby achieving storage and facilitating transportation and use.

[0045] The technical solution of this utility model involves setting up a first support mechanism 1a and a second support mechanism 1b. The second support mechanism 1b and / or the first support mechanism 1a include a fixed component 11, a first support component 12, and a second support component 13. The fixed component 11 is used to connect the mobile lighting fixture. One end of the first support component 12 and the second support component 13 is rotatably mounted on the fixed component 11 to adjust the angle between the first support component 12 and the second support component 13. The other end of the first support component 12 and the second support component 13 is used to abut against the ground to support the anti-tipping support device 100 of the mobile lighting fixture. Thus, in practical applications, the first support mechanism 1a and the second support mechanism 1b can be assembled together, and then the first support component 12 and the second support component 13 can be rotated relative to the fixed component 11 to increase the angle between the first support component 12 and the second support component 13, thereby increasing the contact area between the mobile lighting fixture on the fixed component 11 and the ground, improving the installation stability of the mobile lighting fixture, and improving the problem that existing mobile lighting fixtures are prone to collapse during use.

[0046] Reference Figure 2 and Figure 5 In one embodiment of the present invention, the fixing component 11 includes a fixing seat 111 and a rotating shaft 112 disposed on the fixing seat 111.

[0047] The first support assembly 12 and / or the second support assembly 13 include a rotating rod and a support rod. One end of the rotating rod is sleeved on the rotating shaft 112, and the other end of the rotating rod is sleeved on the support rod. The end of the support rod away from the rotating rod is used to abut against the ground.

[0048] It is understood that there are many ways to implement the fixing component 11, the first support component 12, and the second support component 13. In this embodiment, the fixing component 11 includes a fixing seat 111 and a rotating shaft 112, with the rotating shaft 112 mounted on the fixing seat 111. At least one of the first support component 12 and the second support component 13 includes a rotating rod and a support rod.

[0049] As an example, the first support assembly 12 includes a first rotating rod 121 and a first support rod 122, and the second support assembly 13 includes a second rotating rod 131 and a second support rod 132. One end of the first rotating rod 121 is sleeved on the rotating shaft 112, and the other end of the first rotating rod 121 is sleeved on the first support rod 122. The end of the first support rod 122 away from the first rotating rod 121 is used to abut against the ground. One end of the second rotating rod 131 is sleeved on the rotating shaft 112, and the other end of the second rotating rod 131 is sleeved on the second support rod 132. The end of the second support rod 132 away from the second rotating rod 131 is used to abut against the ground. With this design, when the mobile lighting fixture anti-tipping support device 100 of this embodiment is needed to support the mobile lighting fixture, the first support rod 122 and the second support rod 132 can be placed against the ground to support the entire device. In addition, since the first rotating rod 121 and the second rotating rod 131 are in a vertically overlapping state before they are rotated, the first rotating rod 121 and the second rotating rod 131 can be rotated to increase the angle between the first rotating rod 121 and the second rotating rod 131, which can improve the stability of the first support rod 122 and the second support rod 132 on the ground, thereby improving the installation stability of the mobile lighting fixture. When the mobile lighting fixture anti-tipping support device 100 of this embodiment is not needed, the first rotating rod 121 and the second rotating rod 131 can be rotated to make the first rotating rod 121 and the second rotating rod 131 overlap in the vertical direction. That is, the first support mechanism 1a and the second support mechanism 1b form an integrated structure by rotating and overlapping, which can be stored and is convenient for transportation and use.

[0050] Reference Figure 3 and Figure 6 In one embodiment of the present invention, the rotating shaft 112 includes a first sub-shaft 112a and a second sub-shaft 112b that are offset from each other along the height direction of the fixed seat 111.

[0051] The first support assembly 12 includes a first rotating rod 121 and a first support rod 122. One end of the first rotating rod 121 is sleeved on the first sub-shaft 112a, and the other end of the first rotating rod 121 is sleeved on the first support rod 122. The end of the first support rod 122 away from the first rotating rod 121 is used to abut against the ground.

[0052] The second support assembly 13 includes a second rotating rod 131 and a second support rod 132. One end of the second rotating rod 131 is sleeved on the second sub-shaft 112b, and the other end of the second rotating rod 131 is sleeved on the second support rod 132. The end of the second support rod 132 away from the second rotating rod 131 is used to abut against the ground.

[0053] Based on the above examples, in this embodiment, by dividing the rotating shaft 112 into a first sub-shaft 112a and a second sub-shaft 112b, the first rotating rod 121 of the first support assembly 12 and the second rotating rod 131 of the second support assembly 13 can each be sleeved on the first sub-shaft 112a and the second sub-shaft 112b, respectively. Thus, the first rotating rod 121 and the second rotating rod 131 can rotate independently without interfering with each other, improving the problem that the first rotating rod 121 and the second rotating rod 131 are easily interfered with each other when located on the same rotating shaft 112, thus affecting the rotation effect. Furthermore, since the first sub-shaft 112a and the second sub-shaft 112b only need to be sleeved on one rotating rod, compared to the case in the above embodiment where the rotating shaft 112 is sleeved on two rotating rods, the length of the sub-shaft can be designed to be shorter, effectively reducing the volume of the mobile lighting fixture anti-tipping support device 100.

[0054] Reference Figure 3 and Figure 6 In one embodiment of the present invention, the fixed base 111 is provided with a first limiting part 141 and a second limiting part 142, and the rotating rod can rotate and switch between the first limiting part 141 and the second limiting part 142.

[0055] In this embodiment, a limiting plate 14 is provided on the fixed base 111. The limiting plate 14 is located on one side of the rotating shaft 112. The limiting plate 14 has a first end and a second end opposite to each other along the length direction. The first end of the limiting plate 14 is a first limiting part 141, and the second end of the limiting plate 14 is a second limiting part 142. The rotating rod is restricted to rotate between the first limiting part 141 and the second limiting part 142. That is, the rotation range of the rotating rod is limited by the first limiting part 141 and the second limiting part 142 to avoid the rotation range of the rotating rod being too large, which would be detrimental to the stability adjustment of the mobile lighting fixture.

[0056] Reference Figure 3 and Figure 6 In one embodiment of the present invention, the fixing component 11 further includes a guide shaft 113 disposed on the fixing base 111. The guide shaft 113 and the rotating shaft 112 are spaced apart along the length direction of the rotating rod. The end of the rotating rod away from the corresponding support rod is sleeved on the guide shaft 113 and the rotating shaft 112.

[0057] In this embodiment, when the rotating rod rotates around the rotating shaft 112, the guide shaft 113 mainly guides the rotation of the rotating rod, thereby improving the efficiency of opening and using the first support assembly 12 and / or the second support assembly 13. Furthermore, the guide shaft 113 can also serve a redundancy function; that is, if the rotating shaft 112 is damaged, the guide shaft 113 can replace the rotating shaft 112 and assist the rotating rod in rotating, allowing the corresponding support mechanism to continue to be used.

[0058] In another embodiment of the present invention, in response to the above example, the guide shaft 113 includes a third sub-shaft 113a and a fourth sub-shaft 113b, which are offset from each other along the height direction of the fixed base 111. The third sub-shaft 113a is positioned close to the first sub-shaft 112a. The third sub-shaft 113a and the first sub-shaft 112a are spaced apart along the length of the first rotating rod 121. The end of the first rotating rod 121 away from the first support rod 122 is sleeved on the third sub-shaft 113a and the first sub-shaft 112a. The rotation of the first rotating rod 121 is guided by the third sub-shaft 113a, thereby improving the efficiency of opening and using the first support assembly 12. The fourth sub-shaft 113b is positioned close to the second sub-shaft 112b. The fourth sub-shaft 113b and the second sub-shaft 112b are spaced apart along the length of the second rotating rod 131. The end of the second rotating rod 131 away from the second support rod 132 is sleeved on the fourth sub-shaft 113b and the second sub-shaft 112b. The rotation of the second rotating rod 131 is guided by the fourth sub-shaft 113b, thereby improving the efficiency of opening and using the second support assembly 13.

[0059] Reference Figure 3 and Figure 6 In one embodiment of the present invention, the fixed base 111 is provided with a plurality of through holes 114 for the guide shaft 113 to pass through. The plurality of through holes 114 are arranged in two rows at circumferential intervals along the rotating shaft 112, and each pair of through holes 114 are correspondingly arranged along the height direction of the fixed base 111.

[0060] In this embodiment, the fixed base 111 is provided with multiple through holes 114, which are arranged in two rows at intervals along the circumference of the rotating shaft 112. The number of through holes 114 in each row can be three, four, etc., and is not limited here. Every two through holes 114 are arranged correspondingly along the height direction of the fixed base 111 for the guide shaft 113 to pass through. By installing the guide shaft 113 in different through holes 114 in the same row, the rotation range of the rotating rod is changed, so that the mobile lighting fixture anti-tipping support device 100 of this embodiment can be applied to different sites and meet the usage requirements of different sites.

[0061] Reference Figure 4 and Figure 7 In one embodiment of this utility model, the support rod is threadedly connected to the rotating rod.

[0062] In this embodiment, when it is necessary to adjust the lighting effect of the portable lighting fixture for different usage scenarios, the support rods of the first support mechanism 1a and the second support mechanism 1b can be rotated respectively, so that the rotating rod moves on the corresponding support rod to adjust the installation height of the portable lighting fixture and achieve different lighting effects.

[0063] Reference Figure 8 In one embodiment of the present invention, the fixing component 11 is used for detachable connection to a mobile lighting fixture;

[0064] Alternatively, the fixing component 11 is used for fixed connection to a mobile lighting fixture.

[0065] It is understandable that the connection between the fixing component 11 and the portable lighting fixture can be either a fixed connection or a detachable connection. When the fixing component 11 is fixedly connected to the portable lighting fixture, the fixing method can improve the installation stability of the portable lighting fixture on the portable lighting fixture anti-tipping support device 100; when the fixing component 11 is detachably connected to the portable lighting fixture, if the portable lighting fixture is damaged, it can be removed from the fixing component 11 for replacement, or the portable lighting fixture can also be removed from the fixing component 11 when it is being transported and used, making it convenient for packing and transportation.

[0066] Reference Figure 4 , Figure 7 and Figure 8 In one embodiment of the present invention, at least one of the first support mechanism 1a and the second support mechanism 1b is provided with a snap-fit ​​hole 15 for the snap fastener to pass through.

[0067] It is understood that the first support mechanism 1a and the second support mechanism 1b are detachably connected, specifically through snap-fit ​​connection, magnetic connection, plug-in connection, etc. As an example, the first support mechanism 1a and the second support mechanism 1b are snap-fit ​​connected. Specifically, the first support mechanism 1a and the second support mechanism 1b each include a fixing base 111. The fixing base 111 of the first support mechanism 1a and the fixing base 111 of the second support mechanism 1b are respectively provided with snap-fit ​​holes 15. Screws and other snap-fit ​​components pass through the snap-fit ​​holes 15 of the first support mechanism 1a and the second support mechanism 1b, respectively, thus achieving the connection between the first support mechanism 1a and the second support mechanism 1b. The connection method is simple and convenient, effectively improving the ease of assembly of the first support mechanism 1a and the second support mechanism 1b.

[0068] This utility model also proposes a mobile lighting device, which includes a mobile lighting fixture; and / or a mobile lighting fixture anti-tipping support device 100. The specific structure of the mobile lighting fixture anti-tipping support device 100 is as described in the above embodiments.
