Description

Technical Field

[0001] The present invention belongs to the technical field of advertising stands, and more particularly, relates to an electric telescopic advertising stand. Background Art

[0002] Advertising stands are efficient and intuitive display tools. With their simple structure, diverse designs, and strong visual impact, they have become a vital vehicle for product promotion, brand awareness, and information dissemination. They not only highlight product features but also accurately convey marketing information, effectively enhancing consumer purchasing desire and significantly boosting sales and brand promotion. However, some existing advertising stands are fixed structures that cannot adapt to the height requirements of different venues. Telescopic advertising stands, on the other hand, have large gaps between their structures, making them susceptible to wind damage and lacking stability adjustment mechanisms. Furthermore, the process of disassembling the advertising stand and billboard via bolts is cumbersome. Therefore, a telescopic advertising stand with convenient operation, compact structure, and stability is needed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an electric telescopic advertising stand, which can meet the requirements of convenient operation, compact structure and stability of the advertising stand.

[0004] The electric telescopic advertising stand of the present invention comprises a supporting leg, a telescopic aluminum tube, several suspension units, a motor and a screw. The upper end of the supporting leg is fixedly connected to the bottom end of the telescopic aluminum tube. The bottom end of each section of the telescopic aluminum tube is provided with a plurality of nuts fixedly connected to the tube body. The screw is installed inside the telescopic aluminum tube and is threadedly connected to the nut. The upper section of each independent section of the telescopic aluminum tube is fixedly sleeved with an independent suspension unit. The motor is installed at the bottom end of the telescopic aluminum tube, and the output end of the motor is connected to the tail end of the screw. The suspension unit comprises a grid hanging plate, a joint sleeve, a support bar and a grid. The joint sleeve is fixedly sleeved on the upper section of the independent section tube of the telescopic aluminum tube, and the two ends of the joint sleeve are fixedly connected to the support bar, the truss hanging plate is fixedly installed on one side of the support bar by bolts, and the upper end of the truss is hung on the truss hanging plate; a locking hole is opened on the side of each section tube of the telescopic aluminum tube, and a locking pin that can be slidably connected to the locking hole is installed inside the joint sleeve, and the lower end of the locking pin is provided with a protruding shaft pin groove, and the upper end of the joint sleeve is provided with a snap hook that matches the lock buckle of the joint sleeve on the upper level, the shaft pin groove and the snap hook can be disconnected, and the shaft pin groove can be moved to disconnect it from the snap hook.

[0005] As a further improvement of the present invention, the joint sleeve also includes a spring groove and a spring. The spring groove is opened at the end of the joint sleeve away from the telescopic aluminum tube. The spring is placed in the spring groove. The end of the spring that contacts the bottom of the spring groove is fixedly connected to the spring groove. A through hole is provided on the inner side of the joint sleeve for one end of the locking pin to pass through. One end of the locking pin is slidably connected to the through hole, and the other end compresses the spring in the spring groove. The locking pin is slidably connected to the joint sleeve.

[0006] As a further improvement of the present invention, bar block plugs are fixedly installed at both ends of the support bar to increase the stability of the advertising frame. Support frame bars are fixedly installed on the upper end of the side of the support bar. The support frame bars are bolted to the grid hanging plates to increase the connection area of ​​the grid in the advertising frame and prevent the grid from being tilted or damaged due to force, causing the advertisement to be skewed.

[0007] As a further improvement of the present invention, a motor sleeve is provided on the outside of the motor to provide support for the motor and prevent the motor from being damaged by impact. A connecting bearing is provided at the output end of the motor, and the inner and outer sides of the bearing are respectively connected to the motor and the tail end of the screw. It also includes a battery and a two-way relay. The battery and the two-way relay are fixedly installed on the upper end of the lowest support bar. The positive pole of the battery is electrically connected to the common end of the two-way relay, and the negative pole is electrically connected to the negative pole of the motor. The two control contacts of the two-way relay are electrically connected to the positive and negative poles of the motor, and the coil signal of the two-way relay is connected to an external remote control. When the extension button of the external remote control is triggered, the remote control sends an extension signal to the two-way relay, and one control contact of the two-way relay triggers the positive pole of the motor, so that the motor rotates forward and drives the screw to rotate forward, thereby realizing the extension of the telescopic aluminum tube; when the retraction button of the external remote control is triggered, the remote control sends a retraction signal to the two-way relay, and the other control contact of the two-way relay triggers the negative pole of the motor, so that the motor reverses and drives the screw to reverse, thereby realizing the retraction of the telescopic aluminum tube.

[0008] As a further improvement of the present invention, the telescopic aluminum tube is composed of several single-section aluminum tubes that are coaxially slidably nested, and the diameters of the several single-section aluminum tubes of the telescopic aluminum tube gradually decrease from bottom to top. When any two adjacent single-section aluminum tubes run to the point where their locking holes and through holes coincide with each other, the locking pin pops out to lock the two adjacent single-section aluminum tubes, and the section of aluminum tube can then drive the next-level aluminum tube to telescope.

[0009] As a further improvement of the present invention, the supporting legs include a balancing leg and a pair of triangular legs. The pair of triangular legs are rotatably connected to both sides of the balancing leg. The triangular legs can change the horizontal angle between themselves and the balancing leg by rotating, so that they are perpendicular or parallel to the balancing leg. When vertical, the contact area between the supporting legs and the ground is increased, thereby increasing stability. When parallel, the volume of the support frame is reduced, which is convenient for carrying and transportation.

[0010] As a further improvement of the present invention, a grid pressing card is fixedly connected to the outer side of the grid hanging plate by bolts, and the grid body is hung on the grid pressing card. The tightness of the grid hanging on the grid pressing card is adjusted by adjusting the gap between the grid pressing card itself and the grid hanging plate by bolts, which is convenient for hanging and taking out the grid. Grid guide cards are provided between adjacent grid bodies, and the two ends of the grid guide cards respectively buckle the adjacent grid bodies on the grid hanging plate, so that when the advertising frame is extended or retracted, the grid can be raised and lowered synchronously with the adjacent grids, thereby increasing the stability of the grid.

[0011] As a further improvement of the present invention, the support bars are provided with connecting arms with gradually increasing extension lengths from bottom to top. The support bars are fixedly connected to the grid hanging plates through the connecting arms with gradually increasing lengths, thereby preventing the grid hanging plates from interfering with each other during the extension and retraction process, and making the grid hung on the grid hanging plates in a side stacking state in the retracted state, thereby increasing the stability of the advertising stand.

[0012] As a further improvement of the present invention, the grid can be equipped with display support accessories, colored lights and lighting fixtures accessories. The additional display support parts can fix the display items on the grid surface, thereby expanding the use scenarios of the advertising rack as a multi-functional display rack; all accessories are detachable and hanging, which is convenient for configuration according to display needs, and the installation process will not affect the original telescopic function and structural stability of the advertising rack.

[0013] Compared with the existing technology, the beneficial effects of the present invention are: quick locking and unlocking are achieved through the cooperation of the axle pin groove and the locking hook. Compared with the traditional bolt fixing method, the operation is more convenient, and the structural gap is eliminated, thereby improving the overall stability; the triangular support legs and the balance support legs are foldable, which increases the support stability when unfolded and greatly reduces the volume after folding, which is convenient for transportation and storage; the grid adopts a double fixing method of hooks and bolts, which not only ensures a firm installation, but also facilitates quick disassembly and replacement of advertising content; a grid pressing card and a grid guide card are provided, and the gap between the grid pressing card itself and the grid hanging plate is adjusted by bolts to adjust the tightness of the grid hanging on the grid pressing card, which is convenient for hanging and removing the grid; when the advertising frame is extended or retracted, the grid can be raised and lowered synchronously with the adjacent grids, thereby increasing the stability of the grid.

DETAILED DESCRIPTION

[0016] Specific embodiment 1: Please refer to Figures 1-12The present invention relates to an electric telescopic advertising stand, comprising a supporting leg 1, a telescopic aluminum tube 2, several suspension units 3, a motor 7 and a screw 9. The upper end of the supporting leg 1 is fixedly connected to the bottom end of the telescopic aluminum tube 2. The telescopic aluminum tube 2 is composed of several coaxial sliding nested single-section aluminum tubes, and the diameters of the several single-section aluminum tubes of the telescopic aluminum tube 2 gradually decrease from bottom to top. The bottom end of each single-section aluminum tube is provided with a nut 21 fixedly connected to the tube body. The screw 9 is installed inside the telescopic aluminum tube 2 and threadedly connected to the nut 21. The upper section of each independent section of the telescopic aluminum tube 2 is fixedly sleeved with an independent suspension unit 3. The motor 7 is installed at the bottom end of the telescopic aluminum tube 2, and the output end of the motor 7 is connected to the tail end of the screw 9. The suspension unit 3 comprises a grid hanging plate 4, a joint sleeve 5, a support bar 6 and a grid 8. The joint sleeve 5 is fixedly sleeved on the upper section of the independent section tube of the telescopic aluminum tube 2. The two ends of the joint sleeve 5 are respectively fixedly connected to the two support bars 6 to form a movable whole. The grid hanging plate 4 is fixedly installed on the front side of the support bar 6 (except the support bar 6 at the lower end) by bolts. The upper end of the grid 8 is hung on the grid hanging plate 4, and the advertising board is affixed to the grid 8. Locking holes 22 are opened on the upper and lower sides of each single section aluminum tube of the telescopic aluminum tube 2. A locking pin 53 that can be slidably connected to the locking hole 22 is installed inside the joint sleeve 5, and an axle pin groove 54 is provided at the lower end of the locking pin 53. The upper end of the joint sleeve 5 is provided with a snap hook 55 that matches the lock buckle 53 of the joint sleeve 5 on the upper level of the joint sleeve 5. When the two joint sleeves 5 are close to each other, the axle pin groove 54 is engaged with the snap hook 55, and the locking pin 53 is not inserted into the locking hole 22. When any two adjacent single-section aluminum tubes run to each other's locking holes 22 and overlap to the locking pin 53, the locking pin 53 can automatically pop out and snap into the locking hole 22, so that the two adjacent single-section aluminum tubes are locked, and the aluminum tube section can drive the next level of aluminum tube to extend and retract.

[0017] In a further embodiment, Figure 6-Figure 7 As shown, the joint sleeve 5 also includes a spring groove 51 and a spring 52. The spring groove 51 is opened at the end of the joint sleeve 5 away from the telescopic aluminum tube 2. The spring 52 is placed in the spring groove. The end of the spring 52 that contacts the bottom of the spring groove 51 is fixedly connected to the spring groove 51. A circular through hole is provided on the inner side of the joint sleeve 5 for one end of the locking pin 53 to pass through. One end of the locking pin 53 is slidably connected to the circular through hole, and the other end compresses the spring 52 in the spring groove 51. The engaging hook 55 and the shaft pin groove 54 are provided with mutually matching contact inclined surfaces. When the engaging hook 55 slides on the contact inclined surface of the shaft pin groove 54, the locking pin 53 can slide as a whole in the joint sleeve 5, thereby causing the locking pin 53 to escape from the telescopic aluminum tube 2, completing the locking of the shaft pin groove 54 and the engaging hook 55.

[0018] In a further embodiment, Figure 5As shown, bar block plugs 61 are fixedly installed at both ends of the support bar 6 to increase the stability of the advertising frame. Support frame bars 62 are fixedly installed on the upper end of the side of the support bar 6. The support frame bars 62 are bolted to the grid hanging plate 4 to increase the support area of ​​the grid 8 when it is hung on the grid hanging plate 4, preventing the grid 8 from being tilted or damaged due to force, resulting in skewed advertisements.

[0019] In a further embodiment, Figure 12 As shown, the support bar 6 is provided with connecting arms with gradually increasing extension lengths from bottom to top. The support bar 6 is fixedly connected to the grid hanging plate 4 through the connecting arms with gradually increasing lengths, preventing the grid hanging plates 4 from interfering with each other during the extension and retraction process, and making the grid 8 hung on the grid hanging plate 4 in a side stacking state in the retracted state, thereby increasing the stability of the advertising stand.

[0020] In a further embodiment, Figure 9 As shown, the motor 7 is provided with a motor sleeve 71 on the outside to provide support for the motor 7 and prevent the motor from being damaged by impact. The output end of the motor 7 is provided with a connecting bearing 72. The inner and outer sides of the bearing 72 are respectively connected to the motor 7 and the tail end of the screw 9. It also includes a battery 73 and a two-way relay 74. The battery 73 and the two-way relay 74 are fixedly mounted on the upper end of the lowest support bar 6. The positive pole of the battery 73 is electrically connected to the common end of the two-way relay 74, and the negative pole is electrically connected to the negative pole of the motor 7. The two control contacts of the two-way relay 74 are electrically connected to the positive and negative poles of the motor 7, and the line of the two-way relay 74 is electrically connected. The circle signal is connected to an external remote controller, which is provided with an extend button and a retract button. When the extend button of the external remote controller is triggered, the remote controller sends an extend signal to the two-way relay 74. One control contact of the two-way relay 74 triggers the positive pole of the motor 7, causing the motor 7 to rotate forward and drive the screw 9 to rotate forward, thereby realizing the extension of the telescopic aluminum tube 2; when the retract button of the external remote controller is triggered, the remote controller sends a retract signal to the two-way relay 74. The other control contact of the two-way relay 74 triggers the negative pole of the motor 7, causing the motor 7 to reverse and drive the screw 9 to reverse, thereby realizing the retraction of the telescopic aluminum tube 2.

[0021] In a further embodiment, Figure 8 As shown, the support leg 1 includes a balancing leg 11 and a pair of triangular legs 12. The pair of triangular legs 12 are rotatably connected to both sides of the balancing leg 11. The triangular legs 12 can change the horizontal angle between themselves and the balancing leg 11 by rotating, so that they are perpendicular or parallel to the balancing leg 11. When vertical, the contact area between the support leg 1 and the ground is increased, thereby increasing stability. When parallel, the volume of the support frame is reduced, which is convenient for carrying and transportation.

[0022] In a further embodiment, Figure 11As shown, the outer side of the grid hanging plate 4 is fixedly connected with a grid pressing card 81 by bolts, and the grid 8 body is hung on the grid pressing card 81. The grid pressing card 81 can adjust the gap between itself and the grid hanging plate 4 by bolts to adjust the tightness of the grid 8 body hanging on the grid pressing card 81, which is convenient for hanging the grid 8. A grid guide card 82 is provided between adjacent grid 8 bodies, and the two ends of the grid guide card 82 are respectively engaged with the mesh body of the adjacent grid 8, so that the grid 8 can be raised and lowered synchronously with the adjacent grid 8 when the advertising stand is extended or retracted, thereby increasing the stability of the grid 8.

[0023] When the advertising stand is unfolded and used, the user triggers the extension button of the external remote control, and the dual-channel relay 74 receives the signal to make the motor 7 rotate forward and drive the screw 9 to rotate. At the same time, the nut cooperates with the screw 9 to move and drive the several single-section aluminum tubes in the telescopic aluminum tube 2 to move up and extend in sequence, from the inside to the outside. When the first section of aluminum tube extends from the second section of aluminum tube to the time when the locking pin 53 is matched with the locking hole 22, the elastic force of the spring 52 is released, and the locking pin 53 extends into the second section of aluminum tube and locks it. The screw 9 continues to move, and the first section of aluminum tube drives the second section of aluminum tube to extend, and the axis pin groove 54 of the upper section of aluminum tube engages with the locking hook 5 of the lower section of aluminum tube. 5 is disconnected, and the second section of aluminum tube is extended from the third section of aluminum tube until the locking pin 53 is matched with the locking hole 22. The elastic force of the spring 52 is released, and the locking pin 53 extends into the third section of aluminum tube and locks it. And so on, all the aluminum tubes are extended. When the last section of aluminum tube is extended to the limit, the extension button of the external remote control is released, and the motor 7 stops rotating. During the extension of each section of aluminum tube, the joint sleeve 5 fixedly connected to it and the support bar 6 fixedly connected to the joint sleeve 5 are driven, so that the support bar 6 is raised one by one, and the grid frame 8 connected to it is raised, and the advertising stand is unfolded; When the advertising stand needs to be stored, the user triggers the retraction button of the external remote control, and the dual-channel relay 74 receives the signal to reverse the motor 7 and drive the screw 9 to reverse, and at the same time drive the several single sections of the telescopic aluminum tube 2 to retract in sequence, which is opposite to the above-mentioned aluminum tubes moving up and extending in sequence. From top to bottom, when the penultimate aluminum tube is retracted into the penultimate aluminum tube, the engaging hook 55 of the penultimate aluminum tube joint sleeve 5 contacts the shaft pin groove 54 of the penultimate aluminum tube joint sleeve 5, and the inclined surface of the engaging hook 55 presses against the inclined surface of the shaft pin groove 54, and causes the locking pin 53 to compress the spring 5 2 slides, and when the axle pin groove 54 is fully engaged with the engaging hook 55, the locking pin 53 disengages from the locking hole 22 of the telescopic aluminum tube 2, and the supporting bar 6 of this section presses on the supporting bar 6 below it, so that the joint sleeve 5 and the single aluminum tube fixedly connected to the supporting bar 6 have no space to move downward and shrink, then the third aluminum tube that is unlocked from the second to last aluminum tube continues to shrink downward, and the remaining supporting bars 6 and telescopic aluminum tube 2 shrink step by step until all the aluminum tubes shrink step by step, and the grid 8 descends along with the supporting bars 6 and finally becomes a side stacking state, and the advertising stand is folded up.
