Description

Technical Field

[0001] This utility model relates to the technical field of portable lighting equipment, and more specifically, to a lighthouse mobile device and a portable lighting equipment. Background Technology

[0002] With the continuous development of society and the economy, the pace of life for people who work and strive in urban environments is gradually accelerating, and work pressure is also increasing. Against this backdrop, escaping the hustle and bustle of the city on holidays and weekends to engage in recreational activities such as camping and small gatherings outdoors has become an important choice for this group to relieve mental stress and relax. In these outdoor recreational activities, portable lighthouses, as core nighttime lighting devices, provide stable and reliable light source support for the activity area, directly affecting the safety and experience of the activity; therefore, their application in outdoor scenarios is increasingly demanding.

[0003] However, existing portable lighthouses on the market still have significant technical shortcomings in practical applications, making them difficult to fully adapt to the needs of beach environments. On the one hand, portable lighthouses generally lack convenience when moving in soft outdoor areas like beaches, as they are easily affected by the soft ground, making operation laborious and inefficient. On the other hand, some portable lighthouses are designed to occupy too much space to meet functional requirements such as lighting range or battery life, which not only increases the space occupied during transportation and storage but also further limits their applicability in scenarios such as beaches where flexible repositioning is required, failing to meet users' core demand for portable lighthouses to be "small in footprint and easy to move". Utility Model Content

[0004] The purpose of this utility model is to provide a lighthouse mobile device and a portable lighting equipment to solve the technical problems of portable lighthouses being inconvenient to move on beach sites and occupying too much space in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] In a first aspect, a lighthouse mobile device is provided, comprising:

[0007] The frame has slots for mates with connectors for the lighthouse;

[0008] A wheel axle is connected to the frame, and the wheel axle extends from the frame to both sides to form two connecting ends;

[0009] A wheel body is provided on the connecting end, and the wheel body is capable of rotating around the wheel axle;

[0010] A triggering structure is connected to the axle and is capable of rotating around the axle;

[0011] A hook shaft is provided on the frame and spaced apart from the wheel axle;

[0012] A hook structure is connected to the hook shaft and can rotate around the hook shaft. The hook structure is provided with a hook part located in the slot and a force-receiving part that cooperates with the trigger structure.

[0013] An elastic element connects the hook structure to the frame, and the elastic element is used to apply elastic force to the hook structure to drive the hook structure to rotate around an axis;

[0014] When the trigger structure is pressed down, it applies pressure to the force-bearing part to drive the hook to rotate around the hook shaft to the loose position, and the lighthouse connector can be inserted into the slot; when the pressure applied to the trigger structure is removed, the elastic element drives the hook to rotate around the hook shaft to the hooked position to hook the lighthouse connector located in the slot.

[0015] By adopting the above technical solutions, from the perspective of ease of assembly, the linkage design of the trigger structure and the hook structure allows for the release and reset of the hook with only a single pressure operation, eliminating the need for complex tools and greatly simplifying the assembly and disassembly process of the lighthouse and the device, thus reducing the difficulty of operation for users. From the perspective of connection stability, the continuous elastic force provided by the elastic component ensures that the hook always remains in a tight hooked state with the connecting part, preventing the connection from loosening due to bumps and vibrations during movement on the beach, and ensuring safety in use. From the perspective of mobility and practicality, the design of the wheels rotating around the axle is adapted to the soft surface of the beach. Compared with wheelless or small wheel structures, it can effectively reduce movement resistance, making the lighthouse move more effortlessly on the beach. At the same time, the layout extending on both sides of the axle ensures that the overall force of the device is balanced, making the movement process more stable. From the perspective of space adaptability, the device has a high degree of integration among its components and can be disassembled and separated from the lighthouse without increasing the footprint of the lighthouse when it is not moving. This meets the usage requirements of portable lighthouses that are "small in footprint and easy to store," further enhancing the applicability and practicality of portable lighthouses in outdoor camping, small gatherings, and other scenarios.

[0016] In one embodiment, the frame includes two oppositely arranged side plates and a pedal connecting the two side plates. The two side plate frames are connected to the axle. The side plate has the slot on one side of the axle. The pedal is located on the side of the axle opposite to the slot. The pedal can lift the slot portion of the side plate with the axle as the fulcrum after being pressed by the operator.

[0017] In one embodiment, the frame further includes a cover plate connecting the two side plates, the cover plate and the pedal being located on opposite sides of the wheel axle, and an opening for setting the trigger structure being formed between the cover plate and the pedal.

[0018] In one embodiment, the cover plate has two spaced hook plates, the hook shaft is disposed on the hook plates, and the elastic element is located between the two hook plates and abuts against the hook portion.

[0020] In one embodiment, the frame further includes a second base plate connecting the two side plates, the second base plate being located below the cover plate and spaced apart from the first base plate.

[0021] In one embodiment, the triggering structure includes a pressure frame connected to the wheel axle, a pressure plate connected to one end of the pressure frame, and a pressure-applying part connected to the other end of the pressure frame; the pressure plate protrudes outside the opening, and the pressure-applying part is used to apply pressure to the force-receiving part.

[0022] In one embodiment, the force-receiving part is provided with a limiting part that limits the pressure-applying part, and the limiting part is used to keep the pressure-applying part abutting against the force-receiving part.

[0023] In one embodiment, the hook structure further includes a limiting rod extending toward and abutting the axle to limit the hook structure.

[0024] Secondly, a portable lighting device is provided, including a lighthouse and the aforementioned lighthouse moving device, wherein the lighthouse is provided with a connector that can be detachably inserted into the slot.

[0025] By adopting the above technical solution, in addition to the advantages of the lighthouse mobile device of the above embodiments, the portable lighting device of this embodiment also has the advantages of being easy to move and transport. Attached Figure Description

The specific implementation of this utility model is described in more detail below with reference to specific embodiments:

[0039] like Figures 1 to 3 As shown, an embodiment of this utility model provides a lighthouse mobile device, comprising:

[0040] The frame 1 is provided with a slot 11 for engaging with the connector of the lighthouse;

[0041] A wheel axle 2 is connected to the frame 1, and the wheel axle 2 extends from the frame 1 to both sides to form two connecting ends 21;

[0042] Wheel 3 is mounted on connecting end 21 and can rotate around wheel axle 2;

[0043] Trigger structure 4 is connected to wheel axle 2 and can rotate around wheel axle 2;

[0044] The hook shaft 5 is installed on the frame 1 and spaced apart from the wheel axle 2;

[0045] The hook structure 6 is connected to the hook shaft 5 and can rotate around the hook shaft 5. The hook structure 6 is provided with a hook part 61 located in the slot 11 and a force-receiving part 62 that cooperates with the trigger structure 4.

[0046] Elastic element 7 connects hook structure 6 and frame 1. Elastic element 7 is used to apply elastic force to hook structure 6 to drive hook structure 6 to rotate around axis.

[0047] When the trigger structure 4 is pressed down, the trigger structure 4 applies pressure to the force-bearing part 62 to drive the hook part 61 to rotate around the hook shaft 5 to the loose position, and the lighthouse connector can be inserted into the slot 11; when the pressure applied to the trigger structure 4 is removed, the elastic member 7 drives the hook part 61 to rotate around the hook shaft 5 to the hooked position to hook the lighthouse connector located in the slot 11.

[0048] Please refer to the following: Figure 4 and Figure 5Specifically, the structure of this lighthouse mobile device revolves around facilitating convenient assembly and disassembly with the lighthouse and its movement on the beach. It comprises seven core components: frame 1, axle 2, wheels 3, triggering structure 4, hook axle 5, hook structure 6, and elastic element 7. The frame 1 serves as the basic load-bearing structure, with slots 11 for mating with lighthouse connectors (such as the bottom wheel axle 2), providing a positioning basis for the connection between the lighthouse and the mobile device. The wheel axle 2 is fixedly connected to the frame 1 and extends horizontally from the frame 1 to both sides, forming two symmetrically distributed connection ends 21. The wheels 3 are correspondingly mounted on the two connection ends 21 and can rotate freely around the axis of the wheel axle 2, providing rolling support for the movement of the entire device and the lighthouse. The triggering structure 4 is movably connected to the wheel axle 2, and the trigger... Structure 4 can rotate around the axis of wheel axle 2 and its posture can be adjusted by external force. Hook shaft 5 is fixedly mounted on frame 1 and maintains a preset distance from wheel axle 2. The two are parallel or distributed at a specific angle to adapt to transmission requirements. Hook structure 6 is movably connected to hook shaft 5 and can rotate around the axis of hook shaft 5. Hook structure 6 is integrally formed with hook part 61 located inside slot 11 and force receiving part 62 extending out of slot 11 and correspondingly cooperating with trigger structure 4. Hook part 61 is used to engage with lighthouse connector and force receiving part 62 is used to receive the force of trigger structure 4. One end of elastic member 7 is connected to hook structure 6 and the other end is fixed to frame 1. Elastic member 7 is always in a pre-stretched or pre-compressed state and can continuously apply elastic force to hook structure 6 to drive hook structure 6 to rotate around hook shaft 5.

[0049] When the device needs to be assembled with the lighthouse, downward pressure is applied to the trigger structure 4. The trigger structure 4 rotates around the wheel shaft 2 and transmits the pressure to the force-receiving part 62 of the hook structure 6. Under the action of pressure, the force-receiving part 62 drives the hook structure 6 to rotate around the hook shaft 5, so that the hook part 61 located in the slot 11 rotates synchronously to the loose position. At this time, the internal space of the slot 11 is completely open, and the lighthouse connector can be smoothly inserted into the slot 11 to complete the initial positioning. After the connector is inserted into place, the pressure applied to the trigger structure 4 is removed. After the trigger structure 4 loses the external force constraint, it returns to its initial posture. At the same time, the elastic element 7 releases the pre-stored elastic force, driving the hook structure 6 to rotate in the opposite direction around the hook shaft 5 until the hook part 61 rotates to the hooked position. The hook part 61 and the slot or protrusion structure of the lighthouse connector form a tight engagement, realizing a stable connection between the lighthouse and the device. When disassembly is required, the operation of applying pressure to the trigger structure 4 is repeated, so that the hook part 61 can be released again, making it easy to remove the lighthouse connector from the slot 11.

[0050] By adopting the above technical solutions, from the perspective of ease of assembly, the linkage design of the trigger structure 4 and the hook structure 6 allows the hook 61 to be released and reset with only a single pressure operation, eliminating the need for complex tools and greatly simplifying the assembly and disassembly process of the lighthouse and the device, thus reducing the difficulty of operation for users. From the perspective of connection stability, the continuous elastic force provided by the elastic element 7 ensures that the hook 61 always remains in a tight hooked state with the connecting part, avoiding loosening of the connection due to bumps and vibrations during movement on the beach, and ensuring safety in use. From the perspective of mobility and practicality, the design of the wheel 3 rotating around the wheel axle 2 is adapted to the soft surface of the beach. Compared with wheelless or small wheel structures, it can effectively reduce movement resistance, making the lighthouse move more effortlessly on the beach. At the same time, the layout of the wheel axle 2 extending on both sides ensures that the overall force of the device is balanced, making the movement process more stable. From the perspective of space adaptability, the device has a high degree of integration of each component and can be disassembled and separated from the lighthouse without increasing the footprint of the lighthouse when it is not moving. This meets the usage requirements of portable lighthouses that are "small in footprint and easy to store", further improving the applicability and practicality of portable lighthouses in outdoor camping, small gatherings and other scenarios.

[0051] Please refer to it again. Figure 2 In one embodiment, the frame 1 includes two oppositely arranged side plates 12 and a pedal 13 connecting the two side plates 12. The two side plates 12 are connected to the wheel axle 2. The side plates 12 are provided with slots 11 on one side of the wheel axle 2. The pedal 13 is located on the side of the wheel axle 2 away from the slots 11. The pedal 13 can lift the slots 11 of the side plates 12 with the wheel axle 2 as the fulcrum after being pressed by the operator.

[0052] Specifically, in this embodiment of the lighthouse mobile device, its structural composition revolves around the optimized design of the frame 1 to further adapt to the practical needs of lighthouse assembly and beach movement scenarios. The frame 1 specifically includes two relatively parallel side plates 12 and a pedal 13 for connecting the two side plates 12. The two side plates 12 are fixedly connected to the wheel axle 2 to ensure the assembly stability of the frame 1 and the wheel axle 2. At the same time, each side plate 12 is provided with a slot 11 that cooperates with the lighthouse connector on one side of the wheel axle 2, and the slots 11 on the two side plates 12 are symmetrically distributed to achieve double-sided positioning support for the lighthouse connector. In addition, the pedal 13 is fixedly connected between the two side plates 12, and the installation position of the pedal 13 is located on the side of the wheel axle 2 away from the slot 11, forming a two-sided structural layout with the wheel axle 2 as the dividing point.

[0053] Its working principle is based on the lever principle to achieve flexible adjustment of the position of the slot 11. When the operator needs to assemble the lighthouse connector with the slot 11, downward pressure is applied to the pedal 13. At this time, the wheel axle 2 serves as a fixed fulcrum. After the pedal 13 is subjected to force, it drives the two side plates 12 to rotate synchronously around the wheel axle 2, causing the part of the side plate 12 with the slot 11 to tilt away from the ground, thereby adjusting the opening angle and height of the slot 11. This makes it easier for the operator to accurately align the lighthouse connector and insert it into the slot 11. When the pressure applied to the pedal 13 is removed, the side plate 12 returns to its initial position under its own weight and the connection constraint with the wheel axle 2. The slot 11 also returns to the preset position to cooperate with the lighthouse connector, ensuring that the connector can stably fit the inner wall of the slot 11 after insertion.

[0054] By adopting the above technical solution, on the one hand, the lever structure formed by the pedal 13, side plate 12, and wheel axle 2 allows the operator to apply only a small amount of pressure to adjust the slot 11, significantly reducing the difficulty of aligning the lighthouse connector during insertion. This is especially beneficial in scenarios where the soft sandy ground makes the lighthouse's posture prone to shifting, improving the convenience and efficiency of assembly operations. On the other hand, the symmetrical design of the two opposing side plates 12 and the synchronous tilting of the slot 11 ensure that the lighthouse connector receives uniform support from both sides during insertion, preventing the connector from loosening due to uneven force on one side and enhancing the stability of the connection between the device and the lighthouse. At the same time, the pedal 13 is integrated into the frame 1, eliminating the need for additional adjustment components, simplifying the overall structure of the frame 1, and reducing production and assembly costs. Furthermore, the pedal 13 is located on the side of the wheel axle 2 away from the slot 11, making it less likely to be rotated by the wheel 3 or touched by ground debris during device movement, reducing the possibility of misoperation and further improving the reliability and safety of the device when used on sandy sites.

[0055] In one embodiment, the frame 1 further includes a cover plate 14 connecting the two side plates 12. The cover plate 14 and the pedal 13 are located on both sides of the wheel axle 2, and an opening 15 for setting the trigger structure 4 is formed between the cover plate 14 and the pedal 13.

[0056] Specifically, in this embodiment of the lighthouse mobile device, its structure is further optimized based on the original frame 1. A cover plate 14 is added to connect the two side plates 12. The cover plate 14 and the side plates 12 are fixedly connected to strengthen the overall structure of the frame 1. The cover plate 14 and the pedal 13 are located on both sides of the wheel axle 2. They are symmetrically or correspondingly distributed along the axis of the wheel axle 2. At the same time, a preset interval is maintained between the cover plate 14 and the pedal 13. This interval area forms an opening 15 for accommodating and setting the trigger structure 4. The size of the opening 15 is adapted to the shape of the trigger structure 4 to ensure that the trigger structure 4 can be stably assembled in the opening 15 without interfering with the cover plate 14 and the pedal 13. In addition, the cover plate 14, the pedal 13 and the two side plates 12 together form the main frame of the frame 1. The wheel axle 2, the hook shaft 5 and other components are still connected to the side plates 12 according to the original layout to ensure the continuity of the overall structure.

[0057] Its working principle is as follows: the opening 15 formed by the gap between the cover plate 14 and the pedal 13 provides a dedicated installation space for the trigger structure 4. The trigger structure 4 can be rotatably connected to the frame 1 through the wheel axle 2 and is placed exactly in the opening 15. When the hook structure 6 needs to be triggered, the operator can directly apply downward pressure to the trigger structure 4 in the opening 15. During the rotation of the trigger structure 4 around the wheel axle 2, because the opening 15 has reserved enough space for movement, its rotation will not be blocked by the cover plate 14 or the pedal 13. It can smoothly transmit pressure to the force-bearing part 62 of the hook structure 6, thereby driving the hook part 61 to rotate to the released position. When the pressure is removed, the trigger structure 4 returns to the initial position under its own reset tendency or the linkage of related components. The limiting effect of the opening 15 can prevent the trigger structure 4 from deviating from the preset assembly position due to shaking. At the same time, the cover plate 14 can shield the top of the trigger structure 4, reducing the gap between the trigger structure 4 and other components caused by sand, gravel and other debris falling into the beach environment.

[0058] By adopting the above technical solution, firstly, the structural integration is improved. The addition of the cover plate 14 not only enhances the overall rigidity of the frame 1 by connecting the two side plates 12, preventing the side plates 12 from deforming due to stress when moving on the beach or assembling the lighthouse, but also forms a dedicated opening 15 with the pedal 13, making the layout of the trigger structure 4 more regular, avoiding structural loosening caused by exposed components, and reducing assembly errors. Secondly, the protection of components is optimized. The cover plate 14 effectively shields the trigger structure 4 within the opening 15, reducing the erosion of the rotating joints of the trigger structure 4 by outdoor sand and rainwater, delaying component wear, and improving the lifting device's performance in sandy conditions. The device offers several advantages: 1) Improved service life in complex outdoor environments such as beaches; 2) Enhanced operational reliability, as the opening 15 limits the range of motion of the trigger structure 4, ensuring that the trigger structure 4 rotates along a preset trajectory each time it is subjected to force, avoiding trigger failure due to component misalignment. Additionally, the opening 15 provides the operator with a clear force application area, reducing the probability of misoperation; 3) Enhanced maintenance convenience, as the connection between the cover plate 14 and the side plate 12 (e.g., detachable or flip-up) facilitates subsequent inspection and lubrication of the trigger structure 4 within the opening 15 without disassembling the entire frame 1, saving maintenance time and costs, and further enhancing the practical value of the device.

[0059] In one embodiment, the cover plate 14 is provided with two spaced hook plates 16, the hook shaft 5 is provided on the hook plates 16, and the elastic member 7 is located between the two hook plates 16 and abuts against the hook part 61.

[0060] Specifically, in this embodiment of the lighthouse moving device, its structural composition is further optimized based on the cover plate 14 of the frame 1. Two hook plates 16 are fixedly provided on the side of the cover plate 14 facing the inside of the frame 1, which are parallel to each other at a preset interval. Both hook plates 16 are perpendicular to or at a fixed angle to the cover plate 14, and the positions of the two hook plates 16 correspond precisely to the installation trajectory of the hook structure 6. The two ends of the hook shaft 5 are fixedly connected to the ends of the two hook plates 16 away from the cover plate 14, so that the hook shaft 5 is horizontally mounted between the two hook plates 16, forming The hook structure 6 provides bidirectional support; the elastic element 7 (such as torsion spring, compression spring, elastic plate, etc.) is integrally embedded in the gap between the two hook plates 16. One end of the elastic element 7 is fixed to the frame 1 (or cover plate 14, hook plate 16), and the other end directly abuts against the outer wall of the hook part 61 of the hook structure 6. The elastic element 7 is always in a pre-compressed or pre-stretched state to maintain a continuous force on the hook part 61. At the same time, the distance between the two hook plates 16 matches the length of the elastic element 7 and the width of the hook part 61 to ensure that the abutment state between the elastic element 7 and the hook part 61 is stable and without lateral displacement.

[0061] Its working principle is as follows: the hook structure 6 is rotatably connected to the hook shaft 5 through the middle. When the trigger structure 4 is pressed down and applies force to the force-bearing part 62 of the hook structure 6, the hook structure 6 rotates around the hook shaft 5, causing the hook part 61 to squeeze the elastic element 7 between the two hook plates 16. The elastic element 7 is squeezed and generates elastic deformation and stores potential energy. The hook part 61 rotates synchronously to the loosened position to allow the lighthouse connector to be inserted into the slot 11. When the pressure of the trigger structure 4 is removed, the elastic element 7 releases potential energy and transmits reverse thrust through the contact with the hook part 61, driving the hook structure 6 to rotate in the opposite direction. During this process, the two hook plates 16 form a lateral limit on the elastic element 7 to prevent the elastic element 7 from shifting and causing the force transmission to fail. At the same time, the hook shaft 5 remains stable under the bidirectional support of the two hook plates 16, ensuring that the hook structure 6 rotates smoothly to the hooking position to hook the connector.

[0062] By adopting the above technical solutions, firstly, the structural stability is improved. The two hook plates 16 provide bidirectional support for the hook shaft 5, preventing the hook shaft 5 from deforming and falling off due to repeated rotation of the hook structure 6. At the same time, the limiting elastic element 7 prevents displacement and ensures the precise movement of the hook structure 6. Secondly, the reliability of the elastic element 7 is enhanced. The closed gap formed by the two hook plates 16 can isolate sand and gravel from the beach, reducing the obstruction of debris to the deformation of the elastic element 7 and delaying wear. Moreover, the direct contact between the elastic element 7 and the hook part 61 reduces force transmission loss and ensures efficient reset. Thirdly, the space utilization is optimized. The relevant components are concentrated on one side of the cover plate 14, avoiding interference with the wheel body 3, trigger structure 4, etc., making the overall device more compact. Fourthly, the ease of maintenance is improved. The gap between the two hook plates 16 makes it easy to observe the status of the elastic element 7. During maintenance, there is no need to disassemble the entire frame 1, reducing maintenance difficulty and further adapting to the durability and practicality requirements of outdoor beach scenarios.

[0063] In one embodiment, the frame 1 further includes a first base plate 17 connecting the two side plates 12. The first base plate 17 and the cover plate 14 are located on the same side of the wheel axle 2. The first base plate 17 is located below the cover plate 14. The first base plate 17 is provided with a moving wheel 19.

[0064] Specifically, in the embodiment of the lighthouse mobile device, its structure is based on the existing frame 1, further improving the support and movement structure. The frame 1 adds a first base plate 17 that connects the two side plates 12. The first base plate 17 and the cover plate 14 are located on the same side of the wheel axle 2, and the first base plate 17 is located directly below or at a predetermined lower position of the cover plate 14. Both are fixedly connected to the two side plates 12 to form a closed or semi-closed frame area. At the same time, a moving wheel 19 is installed on the side of the first base plate 17 facing the ground.

[0065] Its working principle is as follows: when the posture of the side plate 12 slot 11 is adjusted by the pedal 13 and the trigger structure 4 drives the hook structure 6 to complete the assembly of the lighthouse connector and slot 11, when the whole device needs to be moved on the beach, the moving wheel 19 on the first base plate 17 and the wheel body 3 on both sides of the original wheel axle 2 form a multi-wheel support structure, which together contact the beach ground. In the process of pushing or pulling the lighthouse, the moving wheel 19 and the original wheel body 3 rotate synchronously around their own axis, and the rolling friction replaces the sliding friction to reduce the resistance with the soft beach ground.

[0066] In one embodiment, the frame 1 further includes a second base plate 18 connecting the two side plates 12, the second base plate 18 being located below the cover plate 14 and spaced apart from the first base plate 17.

[0067] Specifically, in this embodiment of the lighthouse mobile device, its structure is further supplemented with support and protection structures on the basis of the existing frame 1. A second base plate 18 is added to the frame 1 to connect the two side plates 12. The second base plate 18 and the first base plate 17 are located under the cover plate 14, and the second base plate 18 and the first base plate 17 maintain a preset distance. The two ends of the second base plate 18 are fixedly connected to the two side plates 12 respectively (the connection method can be welding, bolt fastening, etc., to ensure a firm connection with the side plates 12). The second base plate 18, the first base plate 17, the cover plate 14, and the two side plates 12 together enclose and form a closed or semi-closed cavity inside the frame 1, which is used to accommodate and protect the core components such as the hook structure 6 and the elastic element 7 located therein.

[0068] Please refer to it again. Figure 4 In one embodiment, the triggering structure 4 includes a pressure frame 41 connected to the wheel axle 2, a pressure plate 42 connected to one end of the pressure frame 41, and a pressure application part 43 connected to the other end of the pressure frame 41; the pressure plate 42 is exposed outside the opening 15, and the pressure application part 43 is used to apply pressure to the force-receiving part 62.

[0069] Specifically, the triggering structure 4 includes three core components: a pressure frame 41, a pressure plate 42, and a pressure application part 43. The pressure frame 41 is rod-shaped or a frame structure adapted to the space of the frame 1. Its middle part is movably connected to the wheel axle 2, and the length of the pressure frame 41 is adapted to the size of the opening 15 formed by the cover plate 14 and the pedal 13 of the frame 1, ensuring that it does not interfere with the surrounding parts after assembly. The pressure plate 42 is integrally formed or fixedly connected to one end of the pressure frame 41. The shape of the pressure plate 42 (such as flat or arc-shaped protrusion) is convenient for the operator to apply force, and the pressure plate 42 is exposed outside the opening 15 between the cover plate 14 and the pedal 13, forming an operating end that can be directly contacted. The pressure application part 43 (which can be a protrusion, arc-shaped contact end, etc.) is fixed to the other end of the pressure frame 41. Its position corresponds precisely to the force-bearing part 62 of the hook structure 6. The contact area and shape of the two match to ensure that the pressure can be stably transmitted. At the same time, the pressure application part 43 is located inside the opening 15 to avoid being exposed and damaged by collisions with foreign objects.

[0070] When the lighthouse connector needs to be inserted into the slot 11, the operator applies a downward force (such as stepping on it with their foot or pressing it with their hand) to the pressure plate 42 exposed at the opening 15. The pressure frame 41 rotates around the axle 2. Since the pressure plate 42 and the pressure application part 43 are located at opposite ends of the pressure frame 41, the downward pressing action of the pressure plate 42 will drive the pressure application part 43 at the other end to move towards the force-receiving part 62 of the hook structure 6 and generate compression through the lever transmission action of the pressure frame 41. Under the pressure, the force-receiving part 62 drives the hook structure 6 to rotate around the hook axis 5. The movement causes the hook 61 located in the slot 11 to rotate synchronously to the loosened position, at which point the lighthouse connector can be smoothly inserted into the slot 11. After the connector is inserted into place and the external force applied to the pressure plate 42 is removed, the elastic element 7 on the frame 1 releases the pre-stored elastic force, driving the hook structure 6 to rotate in the opposite direction to drive the hook 61 to return to the hooked position. At the same time, the force-bearing part 62 generates a reverse thrust on the pressure part 43. This thrust is transmitted to the pressure plate 42 through the pressure frame 41, causing the pressure plate 42 to rotate in the opposite direction around the wheel axle 2 and return to the initial position, waiting for the next operation.

[0071] In one embodiment, the force-receiving part 62 is provided with a limiting part 64 for limiting the pressure-applying part 43, and the limiting part 64 is used to keep the pressure-applying part 43 abutting against the force-receiving part 62.

[0072] Specifically, the limiting part 64 is an integrally formed or fixedly connected structure (such as a claw) on the force-receiving part 62. Its shape and size are precisely matched with the shape of the pressure-applying part 43 of the trigger structure 4. The limiting part 64 is set in the contact area between the force-receiving part 62 and the pressure-applying part 43. The depth or height of the limiting part 64 is preferably such that it can just accommodate part of the pressure-applying part 43 or form a circumferential constraint on the pressure-applying part 43, so as to ensure that the pressure-applying part 43 can be embedded or fit into the limiting part 64 when it contacts the force-receiving part 62. At the same time, the position of the limiting part 64 corresponds to the movement trajectory of the pressure-applying part 43, so as to avoid interference with the up and down rotation of the pressure-applying part 43.

[0073] In one embodiment, the hook structure 6 further includes a limiting rod 63 that extends toward the axle 2 and abuts against the axle 2 to limit the hook structure 6.

[0074] Specifically, in this embodiment of the lighthouse moving device, its structure consists of a new limiting rod 63 added to the hook structure 6. The limiting rod 63 is an extension component integrally formed or fixedly connected to the hook structure 6, and its extension direction is towards the wheel axle 2. The length of the limiting rod 63 is precisely designed to ensure that when the hook structure 6 rotates around the hook shaft 5 to the preset position, the end of the limiting rod 63 away from the main body of the hook structure 6 can form a stable abutment with the outer wall of the wheel axle 2. At the same time, the installation position of the limiting rod 63 avoids the connection area of ​​the hook part 61, the force-bearing part 62 and the elastic member 7 of the hook structure 6, so as to avoid motion interference with other components of the frame 1 (such as the side plate 12, the cover plate 14, and the pressure part 43).

[0075] When the pressure on the trigger structure 4 is released, the elastic element 7 releases its elastic force, causing the hook structure 6 to rotate around the hook shaft 5 to move the hook part 61 towards the hooking position. Simultaneously, the hook structure 6 drives the limiting rod 63 to rotate towards the wheel axle 2. As the hook part 61 gradually approaches the connector, the distance between the limiting rod 63 and the wheel axle 2 continuously decreases until the hook part 61 reaches the preset position where it fully hooks the connector. At this point, the limiting rod 63 just abuts against the outer wall of the wheel axle 2. The wheel axle 2, through its fixed connection with the frame 1, forms a rigid support, preventing the hook structure 6 from being continuously... The hook structure 6 continues to rotate under the force, thus limiting the maximum rotation range of the hook structure 6. When the trigger structure 4 is pressed down, the pressure part 43 pushes the force-receiving part 62 of the hook structure 6 to rotate in the opposite direction around the hook shaft 5, thereby driving the hook part 61 to move towards the release position. At the same time, the hook structure 6 drives the limiting rod 63 away from the wheel axle 2. The contact state between the limiting rod 63 and the wheel axle 2 is released, and it no longer constrains the rotation of the hook structure 6 until the hook part 61 reaches the release position that allows the connector to be inserted. During this process, the movement trajectory of the limiting rod 63 does not collide with other components.

[0076] Secondly, a portable lighting device is provided, including a lighthouse and the aforementioned lighthouse moving device, wherein the lighthouse is provided with a connector that can be detachably inserted into a slot 11.

[0077] By adopting the above technical solution, in addition to the advantages of the lighthouse mobile device of the above embodiments, the portable lighting device of this embodiment also has the advantages of being easy to move and transport.

[0078] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
