[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] like Figure 1As shown, this utility model provides a folding lamp trolley, including: a frame 1 for placing lamps, two retractable tube assemblies 2, and several single tubes 3; aluminum grooves 4 are respectively provided at the upper ends of the four corners of the upper end of the frame 1; the lower end of one tube assembly 2 is rotatably connected to two aluminum grooves 4 by screws 11, so that it can be folded 90° and stored on one side of the upper surface of the frame 1; the lower end of the other tube assembly 2 is rotatably connected to two aluminum grooves 4 by screws 11, so that it can be folded 90° and stored on the other side of the upper surface of the frame 1; tiger claw structures 5 are respectively provided at both ends of the single tubes 3; when the two tube assemblies 2 are in the unfolded state, the tiger claw structures 5 at both ends of the single tubes 3 are respectively engaged with the upper ends of the two tube assemblies 2.

[0018] In this embodiment, as Figure 1-3 As shown, the frame 1 is a rectangular frame structure, mainly used to place lamps and install other components. The four corners of the upper end of the frame 1 are welded or bolted with aluminum channels 4. The core function of the aluminum channels 4 is to provide rotation connection points for the tube assembly 2, and at the same time adapt to the limiting function of the second square pin 7. When in use, when the two tube assemblies 2 are in the unfolded state, the claw structures 5 at both ends of the single tube 3 can be respectively locked at the upper end of the single tube 21 on both sides to form lateral support and prevent the lamps from slipping off the sides of the frame 1. When the tube assembly 2 needs to be stored, the single tube 3 used to support the two tube assemblies 2 can be removed and then flipped and stored on the frame 1. The operation is convenient and quick. The overall structure is stable, easy to operate, and highly adaptable, and can be widely used in the handling and storage scenarios of the lighting industry.

[0019] Further, the tube assembly 2 includes: an inner tube piece 21, a plurality of first square pins 23, and an outer tube piece 22; the lower end of the outer tube piece 22 is rotatably connected to two aluminum grooves 4 respectively by screws 11; the upper end of the outer tube piece 22 is provided with a receiving groove adapted to the lower end of the inner tube piece 21; the lower end of the inner tube piece 21 is telescopically disposed in the receiving groove; the upper end of the inner tube piece 21 can be engaged with the tiger claw structure 5; symmetrical limiting holes are provided on the two side walls of the receiving groove on the outer tube piece 22; a plurality of adjusting holes 24 are provided from top to bottom on the lower end of the inner tube piece 21; the assembly end of the first square pin 23 passes through the limiting hole and is inserted into the adjusting hole 24 to limit and support the inner tube piece 21; stacking male heads 6 are provided on both sides of the upper end of the inner tube piece 21.

[0020] In this embodiment, as Figure 1-3As shown, the inner tube piece 21 is a U-shaped frame structure consisting of two rectangular tubes and one crossbar, while the outer tube piece 22 is a square frame structure consisting of two rectangular tubes and three crossbars. The lower ends of the two rectangular tubes of the outer tube piece 22 are rotatably connected to the aluminum groove 4 at the corner of the frame 1 via screws 11 (the screws 11 pass through the side wall of the aluminum groove 4 and the shaft hole at the lower end of the outer tube piece 22, with a gap to ensure smooth rotation). This connection method allows the outer tube piece 22 to rotate 90° around the screws 11, rotating upwards to be perpendicular to the frame 1 when unfolded, and rotating downwards to fit against the upper surface of the frame 1 when folded, significantly reducing the storage volume. The lower ends of the two rectangular tubes of the inner tube piece 21 The inner tube 21 is adapted to the inner cavity of the upper end of the two rectangular tubes of the outer tube 22, so that the lower end of the entire inner tube 21 can be telescopically installed on the outer tube 22 and fixed by the first square pin 23. The assembly height of the inner tube 21 can be adjusted according to the actual application. The crossbar on the inner tube 21 can be engaged with the tiger claw structure 5 on the single tube 3 for support. At the same time, the upper ends of the two rectangular tubes on the inner tube blade are respectively provided with stacking male head 6 (outer convex structure, matching the inner concave structure of stacking female head 10) for stacking connection after unfolding. The structure is stable, easy to operate, and highly adaptable, and can be widely used in the handling and storage scenarios of the lighting industry.

[0021] Furthermore, it also includes a second square pin 7; the aluminum groove 4 is provided with a through hole for the second square pin 7 to pass through; the lower end of the outer tube piece 22 is provided with a positioning hole that matches the through hole; the assembly end of the second square pin 7 passes through the through hole and is inserted into the positioning hole to limit the outer tube piece 22.

[0022] In this embodiment, as Figure 1-3 As shown, the side wall of the aluminum channel 4 has a through hole, and the lower end of the outer tube 22 has a positioning hole corresponding to the position of the through hole. When the tube assembly 2 is rotated upward to a vertical position, the through hole and the positioning hole are completely aligned. At this time, the assembly end of the second square pin 7 is passed through the through hole and inserted into the positioning hole to restrict the rotation of the outer tube 22. When folding is required, the second square pin 7 is simply pulled out to push the tube assembly 2 downward to complete the folding operation.

[0023] Furthermore, the lower ends of the four corners of the frame are provided with stacking female connectors 10 that are adapted to the stacking male connector 6.

[0024] In this embodiment, as Figure 1-2 As shown, the four corners of the lower end of the frame 1 correspond to the positions of the upper aluminum groove 4, and are integrally formed or bolted to a stacking female head 10. This structure is adapted to the stacking male head 6 on the tube assembly 2 to achieve stacking positioning after folding.

[0025] Furthermore, on the frame 1, a number of cylinders 9 that are adapted to the tiger claw structure 5 are respectively provided in the middle part of the two sides of the segment assemblies 2.

[0026] In this embodiment, as Figure 1-2 As shown, several cylinders 9 are evenly welded along the length direction on the frame 1 near the middle of both sides of the two segment assemblies 2. The cylinders 9 are used to assist in fixing the single tube 3. When the two segment assemblies 2 are folded and gathered on the frame 1, the single tube 3 can be used to press down on the folded segment assemblies 2 to fix the folded segment assemblies.

[0027] Furthermore, a walking assembly 8 is detachably provided at the bottom of the frame 1; the walking assembly 8 includes: a plurality of casters 81; the plurality of casters 81 are detachably provided at the bottom of the frame 1.

[0028] In this embodiment, as Figure 1-2 As shown, the walking assembly includes four casters 81 (with brakes to prevent the trolley from sliding accidentally). The connection between the casters 81 and the frame 1 is detachable: during installation, the connecting shaft of the casters 81 is screwed into the pre-set threaded hole at the bottom of the frame 1, or it is fixed by a snap-fit; during transportation or storage, the casters 81 can be unscrewed or removed to further reduce the overall volume of the trolley, making it easier to stack or pack for transportation.

[0029] In the specific implementation process, when folding, first remove the single tube 3 with the tiger claw structure 5 from the inner tube piece 21. Then, pull out the second square pin 7 to release the limit of the outer tube piece 22. Rotate the tube piece assemblies 2 on both sides downwards by 90° until the inner tube piece 21 and the outer tube piece 22 are completely attached to the upper end face of the frame 1. Finally, snap the single tube 3 with the tiger claw structure 5 to the cylinders 9 on both sides of the frame 1 to press and limit the corresponding folded tube piece assembly 2. When stacking, flip the folded trolley so that the bottom is facing up (or directly align it) so that the stacking female head 10 at the bottom of the frame 1 is aligned with the stacking male head 6 at the top of the inner tube piece 21 of another folding trolley. Slowly lower it and use the concave and convex cooperation of the stacking male head 6 and female head to achieve positioning. 3-5 layers can be stacked (depending on the material strength), which greatly saves storage space.

[0030] This utility model discloses a folding lamp trolley with a stable overall structure. The inner tube extends and retracts along the receiving groove of the outer tube, adapting to lamps of different heights and meeting the needs of different scenarios such as production, transportation, and on-site layout. The tube assembly can be folded 90° to fit the frame, and the volume after folding is only 1 / 3 of the unfolded state. Multi-layer stacking is achieved through the cooperation of stacking male and stacking female heads, improving storage efficiency by 3-5 times. The tiger claw structure enables quick snap-fit / disassembly of single tubes, and the second square pin enables one-click limit / unlocking of the tube assembly. The entire operation requires no tools and can be completed by a single person. The detachable universal wheels have a braking function, making steering flexible and adaptable to different ground environments such as workshops, showrooms, and outdoors. They are also convenient for long-distance transportation after disassembly.
