Description

Technical Field

[0001] This utility model relates to the field of lighthouse technology, and more specifically, to a mobile lighthouse. Background Technology

[0002] Current mobile lighthouse designs suffer from several inconveniences, particularly in the retraction of the support frame and the securing and dismantling of the base plate. Specifically, the retraction process for the support frame in many mobile lighthouses is currently cumbersome and inconvenient. In some designs, the dismantling and retraction of the support frame often requires manual intervention and multiple adjustments to complete.

[0003] The inconvenience of support frame retrieval often stems from a lack of effective automated or simplified retrieval mechanisms in the design. Some traditional mobile lighthouses lack sufficient convenient devices or quick connection mechanisms during the deployment and retrieval of their support frames, requiring operators to invest considerable time and effort in disassembling and retrieving them. Simultaneously, the weight and size of the support frames are typically substantial, occupying significant space during transport and storage, further reducing the efficiency of deployment and dismantling mobile lighthouses in practical use.

[0004] Furthermore, the process of fixing and dismantling the base plates in existing mobile lighthouses presents numerous inconveniences. Base plates are typically used to stabilize the lighthouse, ensuring its stability in various environments. However, in many designs, the fixing method for the base plates is relatively simple, lacking the ability to quickly install and dismantle them. Fixing the base plates may require the use of hand tools or other auxiliary devices for adjustment and securing, while dismantling may require laborious removal of screws, locking devices, or other fixing mechanisms, which is particularly inconvenient in situations requiring rapid installation or dismantling. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides a mobile lighthouse to solve the technical problems mentioned in the background art, such as the inconvenience of retrieving the support frame and the inconvenience of fixing and disassembling the base plate. Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile lighthouse, comprising a support pole, a base frame, a support body retraction mechanism, a ground insertion mechanism, and a stabilizing mechanism. The support body retraction mechanism includes a retraction sleeve and a support frame. The retraction sleeve is slidably mounted on the support pole, and a support frame is rotatably mounted on one end of the support pole. A pull rod is rotatably mounted on the side of the support frame and the retraction sleeve. An external bolt can pass through the retraction sleeve to fix the retraction sleeve to the support pole. A foot plate is mounted on the bottom side of the base frame. The ground insertion mechanism includes an installation sleeve and a pressing rod. An outer support rod is rotatably mounted on the side wall of the installation sleeve, and a transverse support rod is slidably mounted on the side wall of the installation sleeve. An inner spring is installed between the outer support rod and the outer wall of the installation sleeve. One end of the pressing rod can extend into the installation sleeve to push the outer support rod with the transverse support rod. A longitudinal sliding ring is slidably mounted on the outer wall of the installation sleeve, and a locking frame is slidably mounted on the outer wall of the installation sleeve.

[0007] The present invention is further configured such that the stabilizing mechanism includes an outer rotating ring and a double-layer clamping ring. The outer rotating ring is rotatably mounted on the outer wall of the mounting sleeve, and the double-layer clamping ring is fixedly mounted on the outer wall of the mounting sleeve. A clamping ring is installed at the top end of the outer rotating ring, and a bidirectional spring rod is installed on the clamping ring. A positioning hole is opened on the double-layer clamping ring, and the bidirectional spring rod extends into the positioning hole step by step to make the outer rotating ring rotate stably. A threaded plate is installed at the bottom end of the outer rotating ring, and the threaded plate is threadedly connected to the longitudinal moving ring. The rotation of the outer rotating ring causes the longitudinal moving ring to move.

[0008] The present invention is further configured such that a limiting sleeve is fixedly installed on the support rod, and the top end of the retractable sleeve contacts the bottom end of the limiting sleeve. The limiting sleeve is fixedly installed on the support rod and contacts the top end of the retractable sleeve to limit the upward sliding distance of the retractable sleeve and prevent excessive retraction.

[0009] The present invention is further configured such that an installation groove is provided on the base plate, an installation plate is installed on the outer wall of the installation sleeve, and the installation plate is installed in the installation groove. The installation groove is provided on the base plate and cooperates with the installation plate to provide an installation position for the installation sleeve and ensure a stable connection.

[0010] The present invention is further configured such that a pushing groove is provided in the longitudinal moving ring, and the locking frame is slidably connected to the pushing groove. The pushing groove pushes or pulls the locking frame into or away from the pressing rod. The pushing groove is provided in the longitudinal moving ring and is slidably connected to the locking frame, thereby converting the longitudinal movement into the lateral movement and pushing or pulling the locking frame.

[0011] The present invention is further configured such that a return spring is installed on the side wall of the cross brace, and one end of the return spring is connected to the inner wall of the mounting sleeve. The return spring is installed on the side wall of the cross brace and the other end is connected to the inner wall of the mounting sleeve, providing elastic force for the cross brace to return to its original position, ensuring that the cross brace returns to its original position after the pressing pressure is removed.

[0012] The present invention is further configured such that a side wall groove is provided on the side wall of the mounting sleeve, and the outer support rod is rotatably installed in the side wall groove. The side wall groove is provided on the side wall of the mounting sleeve to provide rotation space and guidance for the outer support rod, thereby ensuring the reliability and accuracy of the movement of the outer support rod.

[0013] The present invention is further configured such that a lamp assembly is installed at one end of the support rod, a bottom wheel is installed on one side of the bottom end of the base frame, and a ground-inserting rod is installed at the bottom end of the mounting sleeve. The lamp assembly is installed at one end of the support rod and is the core functional component of the lighthouse, providing lighting function and realizing the basic purpose of the lighthouse. Beneficial effects

[0014] Compared with the prior art, the present invention provides a mobile lighthouse with the following advantages: This utility model is equipped with a support body recovery mechanism. The support body recovery mechanism realizes the rapid deployment and retraction of the lighthouse support structure through the coordinated work of the retraction sleeve, support frame and retraction rod. The design of the external bolt can make the support structure securely locked, and the limiting sleeve prevents over-deployment. This design enables the lighthouse to quickly establish stable support when in use and can be quickly stored when not in use, which greatly improves the portability and ease of use of the lighthouse.

[0015] This utility model is equipped with a ground-insertion mechanism. The ground-insertion mechanism, through the cooperation of the mounting sleeve, pressing rod, outer support rod and cross support rod, realizes the ground fixation of the lighthouse. The design of the inner spring and return spring ensures that the mechanism can automatically reset. The side wall groove provides precise guidance, and the ground-insertion rod provides direct ground support. This design enhances the connection stability between the lighthouse and the ground, prevents it from tipping over due to external forces during use, and improves safety.

[0016] This utility model is equipped with a stabilizing mechanism. The stabilizing mechanism provides precise angle control and locking function through the coordinated work of the outer rotating ring, double-layer clamping ring, clamping ring, bidirectional spring rod and longitudinal moving ring. The threaded connection design makes the adjustment more precise. The push groove and locking frame realize the reliable locking of the pressing rod. This mechanism effectively prevents the lighthouse from loosening due to vibration or external force during use, ensuring that the lighthouse can work stably for a long time and improving the reliability and service life of the overall equipment.

[0022] Please see Figures 1-5 A mobile lighthouse includes a support pole 1, a support body retraction mechanism, a ground insertion mechanism, and a stabilizing mechanism. The support body retraction mechanism includes a retraction sleeve 2 and a support frame 3. The retraction sleeve 2 is slidably mounted on the support pole 1. The support frame 3 is rotatably mounted on one end of the support pole 1. A pull rod 4 is rotatably mounted on the side of the support frame 3 and the retraction sleeve 2. An external bolt can pass through the retraction sleeve 2 to fix the retraction sleeve 2 to the support pole 1. A foot plate 5 is mounted on the side of the bottom end of the base frame 101. The ground insertion mechanism includes an installation sleeve 6 and a pressing rod 7. An outer support rod 8 is rotatably mounted on the side wall of the installation sleeve 6. A horizontal support rod 9 is slidably mounted on the side wall of the installation sleeve 6. An inner spring 10 is installed between the outer support rod 8 and the outer wall of the installation sleeve 6. One end of the pressing rod 7 can extend into the installation sleeve 6 to push the outer support rod 8 with the horizontal support rod 9. A longitudinal sliding ring 11 is slidably mounted on the outer wall of the installation sleeve 6. A locking frame 12 is slidably mounted on the outer wall of the installation sleeve 6.

[0023] In this embodiment, the support retraction mechanism realizes the expansion and retraction of the support structure through the retraction sleeve 2 and the support frame 3. In use, the retraction sleeve 2 can slide on the support rod 1, the support frame 3 is rotatably installed at one end of the support rod 1, and the pull rod 4 connects the support frame 3 and the retraction sleeve 2. When it is necessary to expand the support, the retraction sleeve 2 is slid downward, and the pull rod 4 drives the support frame 3 to expand outward, forming a stable support structure. After expansion, the external bolt passes through the retraction sleeve 2 and fixes it to the support rod 1 to maintain the expanded state of the support frame 3. When retracting, the external bolt is removed, the retraction sleeve 2 slides upward, and the support frame 3 retracts accordingly until the top of the retraction sleeve 2 contacts the limiting sleeve 19 on the support rod 1. The retraction process is completed. The ground-insertion mechanism fixes the lighthouse to the ground through the mounting sleeve 6 and the pressing rod 7. The mounting sleeve 6 is installed in the mounting groove 20 of the foot plate 5 through the mounting plate 21. The outer support rod 8 is rotatably installed in the side wall groove 24 of the side wall of the mounting sleeve 6. The inner spring 10 connects the outer support rod 8 and the mounting sleeve 6. When the pressing rod 7 is inserted into the mounting sleeve 6, it pushes the horizontally sliding cross support rod 9. The cross support rod 9 then pushes the outer support rod 8 to unfold outward, overcoming the tension of the inner spring 10, and inserting the outer support rod 8 into the ground. The return spring 23 on the side wall of the cross support rod 9 is connected to the inner wall of the mounting sleeve 6. When the pressing force is removed, the return spring 23 will cause the cross support rod 9 to return to its original position.

[0024] The stabilizing mechanism includes an outer rotating ring 13 and a double-layer clamping ring 14. The outer rotating ring 13 is rotatably mounted on the outer wall of the mounting sleeve 6, and the double-layer clamping ring 14 is fixedly mounted on the outer wall of the mounting sleeve 6. A clamping ring 15 is mounted on the top end of the outer rotating ring 13, and a bidirectional spring rod 16 is mounted on the clamping ring 15. A positioning hole 17 is opened on the double-layer clamping ring 14. The bidirectional spring rod 16 extends into the positioning hole 17 step by step, so that the outer rotating ring 13 rotates stably. A threaded plate 18 is mounted on the bottom end of the outer rotating ring 13. The threaded plate 18 is threadedly connected to the longitudinal moving ring 11. The rotation of the outer rotating ring 13 causes the longitudinal moving ring 11 to move.

[0025] In this embodiment, the stabilizing mechanism enhances the stability of the lighthouse through an outer rotating ring 13 and a double-layer clamping ring 14. The outer rotating ring 13 is rotatably mounted on the outer wall of the mounting sleeve 6, and the double-layer clamping ring 14 is fixedly mounted on the outer wall of the mounting sleeve 6. A bidirectional spring rod 16 is installed on the clamping ring 15 at the top of the outer rotating ring 13, which can extend into the positioning hole 17 of the double-layer clamping ring 14 step by step to ensure that the rotation angle of the outer rotating ring 13 is precisely controllable. A threaded plate 18 is installed at the bottom of the outer rotating ring 13, which is threadedly connected to the longitudinal sliding ring 11 that slides longitudinally on the outer wall of the mounting sleeve 6. When the outer rotating ring 13 is rotated, the longitudinal sliding ring 11 moves longitudinally through the threaded connection. The push groove 22 opened in the longitudinal sliding ring 11 is slidably connected to the locking frame 12, which can push or pull the locking frame 12 into or away from the pressing rod 7 to lock or unlock the pressing rod 7.

[0026] Please see Figures 1-5As a supplementary embodiment of the mobile lighthouse for the support body recovery mechanism, ground insertion mechanism and stabilization mechanism: a limiting sleeve 19 is fixedly installed on the support rod 1, and the top end of the retractable sleeve 2 is in contact with the bottom end of the limiting sleeve 19. An installation groove 20 is opened on the foot plate 5. An installation plate 21 is installed on the outer wall of the installation sleeve 6, and the installation plate 21 is installed in the installation groove 20. A pushing groove 22 is opened in the longitudinal moving ring 11. The locking frame 12 is slidably connected to the pushing groove 22. The pushing groove 22 pushes or pulls the locking frame 12 to extend into or away from the pressing rod 7. A return spring 23 is installed on the side wall of the cross support rod 9, and one end of the return spring 23 is in contact with the inner wall of the installation sleeve 6. A side wall groove 24 is opened on the side wall of the installation sleeve 6, and the outer support rod 8 is rotatably installed in the side wall groove 24. A light assembly 25 is installed on one end of the support rod 1. A bottom wheel 26 is installed on one side of the bottom end of the base frame 101.

[0027] More specifically, the lighthouse can be easily moved to a designated position using the bottom wheel 26 on one side of the base frame 101. The light assembly 25 installed at one end of the support rod 1 is the core functional part of the lighthouse. After reaching the target position, the retractable sleeve 2 is slid down, and the support frame 3 is driven to unfold outward through the retractable rod 4 to form a stable triangular support structure. Then, the position of the retractable sleeve 2 is fixed with an external bolt. The mounting sleeve 6 is installed in the mounting groove 20 of the foot plate 5 through the mounting plate 21. The pressing rod 7 is pushed into the mounting sleeve 6, which drives the cross support rod 9 to push the outer support rod 8 to overcome the tension of the inner retractable spring 10 and unfold outward, inserting into the ground to provide stability. The outer rotating ring 13 is rotated, and the bidirectional spring rod 16 extends into the positioning hole 17 of the double-layer clamping ring 14 step by step to precisely control the rotation angle. Simultaneously, the outer rotating ring 13 drives the longitudinal moving ring 11 to move via the threaded plate 18. The pushing groove 22 of the longitudinal moving ring 11 pushes the locking frame 12 into the pressing rod 7, locking the position of the pressing rod 7 and preventing the outer support rod 8 from retracting. After completing the above steps, the lighthouse is firmly erected on the ground, and the lamp assembly 25 at one end of the support rod 1 can start working to provide lighting. After use, rotate the outer rotating ring 13 in the opposite direction to move the locking frame 12 away from the pressing rod 7, remove the pressing rod 7, and the outer support rod 8 retracts under the action of the inner retraction spring 10. Remove the outer bolt, slide the retraction sleeve 2 upward, and the support frame 3 retracts, returning to a state that is easy to move.

[0028] In summary, during the use or operation of the overall equipment: When the support body retraction mechanism is required, the support body retraction mechanism realizes the expansion and retraction of the support structure through the retraction sleeve 2 and the support frame 3. In use, the retraction sleeve 2 can slide on the support rod 1, the support frame 3 is rotatably installed at one end of the support rod 1, and the pull rod 4 connects the support frame 3 and the retraction sleeve 2. When it is necessary to expand the support body, the retraction sleeve 2 is slid downward, and the pull rod 4 drives the support frame 3 to expand outward, forming a stable support structure. After expansion, the external bolt passes through the retraction sleeve 2 and fixes it on the support rod 1 to maintain the expanded state of the support frame 3. When retracting, the external bolt is removed, the retraction sleeve 2 slides upward, and the support frame 3 retracts accordingly until the top of the retraction sleeve 2 contacts the limiting sleeve 19 on the support rod 1, completing the retraction process.

[0029] When the ground-insertion mechanism is in operation, it fixes the lighthouse to the ground through the mounting sleeve 6 and the pressing rod 7. The mounting sleeve 6 is installed in the mounting groove 20 of the foot plate 5 through the mounting plate 21. The outer support rod 8 is rotatably installed in the side wall groove 24 of the side wall of the mounting sleeve 6. The inner spring 10 connects the outer support rod 8 and the mounting sleeve 6. When the pressing rod 7 is inserted into the mounting sleeve 6, it pushes the horizontally sliding cross support rod 9. The cross support rod 9 then pushes the outer support rod 8 outward to overcome the tension of the inner spring 10 and insert the outer support rod 8 into the ground. The return spring 23 on the side wall of the cross support rod 9 is connected to the inner wall of the mounting sleeve 6. When the pressing force is removed, the return spring 23 will return the cross support rod 9 to its original position.

[0030] When the stabilizing mechanism is required to operate, it enhances the stability of the lighthouse through the outer rotating ring 13 and the double-layer clamping ring 14. The outer rotating ring 13 is limited to rotate and is mounted on the outer wall of the mounting sleeve 6. The double-layer clamping ring 14 is fixedly mounted on the outer wall of the mounting sleeve 6. A bidirectional spring rod 16 is installed on the clamping ring 15 at the top of the outer rotating ring 13, which can be inserted into the positioning hole 17 of the double-layer clamping ring 14 step by step to ensure that the rotation angle of the outer rotating ring 13 is precisely controllable. A threaded plate 18 is installed at the bottom of the outer rotating ring 13, which is threadedly connected to the longitudinal sliding ring 11 that slides longitudinally on the outer wall of the mounting sleeve 6. When the outer rotating ring 13 is rotated, the longitudinal sliding ring 11 is moved longitudinally through the threaded connection. The push groove 22 opened in the longitudinal sliding ring 11 is slidably connected to the locking frame 12, which can push or pull the locking frame 12 into or away from the pressing rod 7 to lock or unlock the pressing rod 7.

[0031] Using the bottom wheels 26 on one side of the base frame 101, the lighthouse can be easily moved to a designated location. The light assembly 25 installed at one end of the support rod 1 is the core functional part of the lighthouse. After reaching the target position, the retractable sleeve 2 is slid downwards, and the support frame 3 is driven to unfold outwards by the retractable rod 4 to form a stable triangular support structure. Then, the position of the retractable sleeve 2 is fixed with external bolts. The mounting sleeve 6 is installed in the mounting groove 20 of the foot plate 5 through the mounting plate 21. The pressing rod 7 is pushed into the mounting sleeve 6, which drives the cross support rod 9 to push the outer support rod 8 to overcome the tension of the inner retractable spring 10 and unfold outwards, inserting into the ground to provide stability. The outer rotating ring 13 is rotated, and the bidirectional spring rod 16 extends into the positioning hole 17 of the double-layer clamping ring 14 step by step to precisely control the rotation angle. Simultaneously, the outer rotating ring 13 drives the longitudinal moving ring 11 to move via the threaded plate 18. The pushing groove 22 of the longitudinal moving ring 11 pushes the locking frame 12 into the pressing rod 7, locking the position of the pressing rod 7 and preventing the outer support rod 8 from retracting. After completing the above steps, the lighthouse is firmly erected on the ground, and the lamp assembly 25 at one end of the support rod 1 can start working to provide lighting. After use, rotate the outer rotating ring 13 in the opposite direction to move the locking frame 12 away from the pressing rod 7, remove the pressing rod 7, and the outer support rod 8 retracts under the action of the inner retraction spring 10. Remove the outer bolt, slide the retraction sleeve 2 upward, and the support frame 3 retracts, returning to a state that is easy to move.
