Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1: Please refer to Figure 1-6 A foldable advertising display board includes a base 100, a folding component 200, and a wind-resistant reinforcement component 300.

[0029] Please refer to the details. Figure 1 The base 100 has a first display panel 110 on its top, several casters 120 on its bottom, and a battery on one end of the bottom inner wall of the base 100.

[0030] Please see Figure 1-5 The folding assembly 200 includes rotating heads 210 rotatably connected to both sides of the first display panel 110. Each rotating head 210 has a connecting strip 220 on one side. The connecting strip 220 has a groove inside. A movable seat 230 is slidably connected inside the groove. A connector 240 is provided on one side of the movable seat 230. A second display panel 250 is rotatably connected between the two connectors 240. Two plugs 260 are provided at the bottom of the second display panel 250. The bottom of each plug 260 is inserted and connected to the first display panel 110.

[0031] In one specific embodiment, the second display panel 250 allows the user to easily fold and move the device when needed. The user slides the locking head 430 out of the moving base 230 via the limiting component 400, releasing the restriction on the moving base 230. The user then holds the handle 1200 and pulls it upwards, causing the second display panel 250 to move upwards. This upward movement of the second display panel 250 causes the plug 260 to slide out of the first display panel 110. Furthermore, the upward movement of the second display panel 250, via the connector 240, causes the moving base 230 to move upwards within the groove of the connecting strip 220. When the plug 260 slides out of the first display panel 110, the restrictions on the connecting strip 220 and the moving base 230 are unlocked. The user then rotates the second display panel 250 to one side, using the rotating head 210 and the connector 240 to rotate the second display panel 250 and the connecting strip 220, thereby folding the second display panel 250 and achieving rapid folding.

[0032] Please see Figure 2-3 The wind-resistant reinforcement component 300 includes two first hinge seats 310 disposed at one end of the first display panel 110. The two first hinge seats 310 are hinged to the inside of each of the two first hinge seats 310. A reinforcement rod 330 is disposed in the middle of the two connecting rods 320. A fixing strip 340 is disposed at the bottom of the two connecting rods 320. Two electric telescopic rods 350 are disposed at the bottom of the inner wall of the base 100. The output shaft ends of the two electric telescopic rods 350 pass through the base 100 and are fixedly connected to the fixing strip 340.

[0033] In one specific embodiment, the connecting rod 320 facilitates the user's movement when unfolding the support. By holding the reinforcing rod 330, the user pulls the connecting rod 320 to one end, causing it to move through the first hinge seat 310. The pull continues until the fixing bar 340 abuts against the blocking plate. At this point, the user opens the electric telescopic rod 350 via the controller, causing it to move upward and insert its end into the fixing bar 340 for fixation, thus achieving triangular support and making it more stable. When folding, the user controls the electric telescopic rod 350 to retract, releasing the restriction on the fixing bar 340. At this time, the torsion springs in the first hinge seat 310 and the connecting rod 320 will return to their original position for subsequent folding, thereby achieving the purpose of wind-resistant reinforcement.

[0034] Please see Figure 1The limiting component 400 includes fixing heads that are both disposed on both sides of the first display plate 110. Each fixing head has a connecting seat 410 on one side. Each connecting seat 410 has a movable rod 420 hinged inside. Each movable rod 420 has a locking head 430 at its end. The ends of the locking heads 430 are inserted into the movable seat 230. Each movable rod 420 has a second hinge seat 440 hinged at its bottom. Each second hinge seat 440 has a movable plate 450 at its bottom. Each movable plate 450 has a screw nut 460 with opposite threads threaded inside. A rotating rod 470 is disposed in the middle of the two screw nuts 460.

[0035] In one specific embodiment, the provided rotating rod 470 allows the user to easily release the restriction on the movable seat 230 when needed. The user rotates the grip head to rotate the worm gear 700, which in turn rotates the worm wheel 600. The worm wheel 600 then rotates the rotating rod 470, causing the two lead screw nuts 460 to rotate. The lead screw nuts 460, through their external threads, engage with other limiting structures, thereby moving the movable plate 450. The two movable plates 450 move towards the center, causing the two second hinge seats 440 to move towards the center. The movement of the second hinge seats 440 moves the movable rod 420, which then lifts up through the connecting seat 410, causing the locking head 430 to slide out of the movable seat 230, thus achieving the purpose of releasing the restriction.

[0036] Please see Figure 3 The first display panel 110 has an auxiliary groove at one end, and a protective box 500 is sealed and connected to one end of the auxiliary groove. A worm gear 600 is provided on the outer wall of the rotating rod 470, and a worm 700 is engaged at the top of the worm gear 600.

[0037] In one specific embodiment, the protective box 500 provides convenient protection for the internal parts during use, preventing damage to the internal parts due to bumps and knocks, and improving stability.

[0038] Please see Figure 6 The outer wall of the worm gear 700 is rotatably connected to a support bar 800. Both sides of the support bar 800 are fixedly connected to the protective box 500. One end of the protective box 500 is hinged to a protective cover 900. One end of the protective cover 900 is provided with a handle, and a door lock is embedded inside the handle.

[0039] In one specific embodiment, the door lock allows users to open the door with a key and then open the protective cover 900 by gripping the handle to operate the internal worm gear 700, thus preventing malfunctions caused by unauthorized personnel.

[0040] Please see Figure 3The outer walls of the two electric telescopic rods 350 are provided with reinforcing plates 1000. Both sides of the reinforcing plates 1000 are fixedly connected to the base 100. The top of the base 100 is provided with a baffle plate, one end of which is movably connected to the fixing strip 340.

[0041] In one specific embodiment, the reinforcing plate 1000 is provided to support and reinforce the electric telescopic rod 350 during use, making the electric telescopic rod 350 more stable during use. After folding, the user can operate the electric telescopic rod 350 to move it upward and insert it into the insertion hole in the auxiliary block 1100 to limit its position, thereby limiting the position of the second display plate 250.

[0042] Please see Figure 1 Two auxiliary blocks 1100 are provided at one end of the second display panel 250. The bottom of each auxiliary block 1100 is provided with a hole. A handle 1200 is provided in the middle of one end of the second display panel 250. A controller is provided on one side of the base 100.

[0043] In one specific embodiment, by providing a second display board 250, users can easily affix promotional posters to the first display board 110 and the second display board 250 for display purposes, thereby achieving the purpose of promotion.

[0044] Please see Figure 1-6 The electric telescopic pole 350 is electrically connected to the controller, and the controller is electrically connected to the battery.

[0045] In one specific embodiment, the provided controller facilitates the power supply to electrical equipment when it needs power, avoiding the situation where power cannot be supplied when power is needed.

[0046] In use, the second display panel 250 facilitates folding and movement. When folding is needed, the user slides the locking head 430 out of the moving base 230 via the limiting component 400, releasing the limitation on the moving base 230. The user then holds the handle 1200 and pulls upwards, causing the second display panel 250 to move upwards. This upward movement causes the plug 260 to slide out of the first display panel 110. The upward movement of the second display panel 250 also causes the moving base 230 to move upwards within the groove of the connecting strip 220 via the connector 240. When the plug 260 slides out of the first display panel 110, the limitations of the connecting strip 220 and the moving base 230 are unlocked. The user then rotates the second display panel 250 to one side, using the rotating head 210 and the connector 240 to rotate the second display panel 250. The second display panel 250 is folded up using the connecting rod 220 and the connecting rod 320, thus achieving rapid folding. Then, the connecting rod 320 allows the user to easily pull the connecting rod 320 to one end by holding the reinforcing rod 330 during the unfolding support. This causes the connecting rod 320 to move to one end via the first hinge seat 310, pulling until the fixing strip 340 abuts against the blocking plate. At this point, the user opens the electric telescopic rod 350 via the controller, causing it to move upwards and insert its end into the fixing strip 340 for fixation, achieving triangular support and further stabilization. During folding, the user controls the electric telescopic rod 350 to retract, releasing the restriction on the fixing strip 340. The torsion springs within the first hinge seat 310 and the connecting rod 320 will then return to their original position for subsequent folding, thus achieving wind-resistant reinforcement.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
