Description

Technical Field

[0001] The invention belongs to the technical field of advertising equipment, in particular to a rotatable and combinable advertising equipment. Background Art

[0002] LED advertising screen, also known as LED advertising display screen, is a display screen composed of LED lamp array. It realizes diversified display of information through various technical means such as photoelectric display technology, video technology, multimedia technology, network technology, computer technology and automatic control technology. LED advertising screen is a screen that controls the display of semiconductor light emitting diodes and is composed of a large number of LED pixels evenly arranged to display various information. In business promotion, LED display screens are often used to promote various advertising promotion information.

[0003] Conventional LED advertising screens are mainly composed of a single screen, which generally plays multiple promotional information on the screen in a loop. Due to the installation position of the advertising screen and its viewing angle, the corresponding information on the advertising screen can only be observed when facing the advertising screen or approaching the advertising screen, while the corresponding promotional advertising information cannot be observed at other angles. At the same time, the loop playback method cannot display multiple information at the same time, and improvement is urgently needed.

[0004] At the same time, due to the size of the LED display, the display area is small and the content displayed at a single time is small. However, due to the high cost of large-size LED displays, the existing technology generally adopts a splicing method to achieve larger content, but the entire splicing process is relatively complicated and requires operators to perform a long splicing process to achieve assembly, and the overall combination efficiency is low. Summary of the invention

[0005] The object of the present invention is to provide a rotatable and combinable advertising device to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a rotatable combinable advertising device, comprising an LED advertising screen arranged at equal angles, a flexible hinge is provided in the middle of the LED advertising screen, a base is provided at the bottom end of the LED advertising screen, a mounting rod is fixedly installed at equal angles on the outer side surface of the flexible hinge, the end of the mounting rod away from the flexible hinge is connected to the middle part of the inner side surface of the LED advertising screen, magnets are installed at both ends of the flexible hinge, and the flexible hinge forms a circular ring shape after being adsorbed and connected by the magnets at both ends, an adjustment component is installed at the top of the base, an extension base located above the adjustment component is fixedly installed at the top of the base, a motor located directly above the flexible hinge is fixedly installed at the bottom end of the inner side surface of the extension base, an extension frame is fixedly installed on one side of the top of the adjustment component, a second electric push rod is fixedly installed on the top of the extension frame, and a positioning hole located directly above the second electric push rod is opened at the bottom end of the magnet.

[0007] In the initial state, multiple LED advertising screens are arranged at equal angles around the outer side of the flexible hinge to form a circular structure. At this time, the device is a rotary advertising device. If the device needs to be combined, multiple LED advertising screens can be arranged in sequence to form a flat plate to meet different needs.

[0008] As a further technical solution of the present invention, a motor is fixedly installed at the bottom end of the extended base, a transmission disk is fixedly installed at the output end of the motor, and limiting holes are provided at equal angles at the bottom end of the transmission disk near the outer side surface.

[0009] As a further technical solution of the present invention, a first electric push rod is fixedly installed at an equal angle on the top end of the flexible hinge, the number of the first electric push rods is the same as the number of the limiting holes, and the top end of the first electric push rod is adapted to the limiting hole, and when the LED advertising screen is formed into a circle, the output end of the first electric push rod is movably connected to the limiting hole.

[0010] As a further technical solution of the present invention, when the LED advertising screen is in a pre-assembled state, the top end of the first electric push rod is disengaged from the interior of the limiting hole, and the top end of the second electric push rod is inserted into the interior of the positioning hole to complete the snap connection.

[0011] When the device needs to be formed into a circle for convenient observation at various angles, the adjustment component can be restored to the initial state. At this time, the flexible hinge can form a circle, and the magnets at both ends are attracted to each other. At this time, the flexible hinge can drive the multiple LED advertising screens to move through the mounting rods on the outer side until the multiple LED advertising screens form a circular structure. At this time, the second electric push rod can be controlled to shorten, and the second electric push rod can be separated from the positioning hole, releasing the locking process between the second electric push rod and the positioning hole;

[0012] When the LED advertising screen and the flexible hinge return to their initial state, the multiple first electric push rods can be turned on and controlled to extend synchronously until the top ends of the first electric push rods are all inserted into the limiting holes. At this time, the assembly between the first electric push rods and the limiting holes can be completed, and the transmission disk can be driven to rotate by turning on the motor. At this time, the multiple first electric push rods can be driven to rotate circumferentially, and finally the flexible hinge can be driven to rotate. At this time, the multiple LED advertising screens will move circumferentially accordingly to complete the rotation display process.

[0013] By setting up multiple LED advertising screens and setting them in a circular shape, and coordinating the first electric push rod and the adjustment component at the bottom and the flexible hinge so that the flexible hinge forms a circle, the multiple LED advertising screens can form a circle, and the cooperation between the first electric push rod and the limiting hole can realize the rapid rotation display of the multiple LED advertising screens, and a single LED advertising screen can display separate content. Through the rotation display of multiple LED advertising screens, different advertising information at different angles can be displayed synchronously, avoiding the problem of single display content and small observation range of traditional devices, thereby improving the advertising dissemination effect.

[0014] As a further technical solution of the present invention, the adjustment component includes a transverse guide rail, a longitudinal guide rail is fixedly installed at the rear end of the transverse guide rail, the transverse guide rail and the longitudinal guide rail are perpendicular to each other, an extension plate is fixedly installed at the bottom end of the transverse guide rail, and the adjustment component also includes a fixed plate, one end of the fixed plate is fixedly connected to a third electric push rod, and the output end of the third electric push rod is connected to the extension plate.

[0015] As a further technical solution of the present invention, a fourth electric push rod is fixedly sleeved on the fixed plate near the top, the bottom end of the fixed plate is connected to the top of the base, the output end of the fourth electric push rod is fixedly connected to a movable plate, and the top of the movable plate is fixedly connected to a longitudinal guide block.

[0016] As a further technical solution of the present invention, the movable plate is movably connected between the longitudinal guide block and the longitudinal guide rail, and the movable plate moves forward and backward relative to the longitudinal guide rail. The first mounting seat is installed on both sides of the movable plate away from one end of the fourth electric push rod.

[0017] As a further technical solution of the present invention, one end of the first mounting seat away from the movable plate is movably connected to a connecting rod via a rotating shaft, and one end of the connecting rod away from the first mounting seat is movably connected to the second mounting seat via a rotating shaft.

[0018] As a further technical solution of the present invention, one end of the second mounting seat away from the connecting rod is fixedly connected to a transverse guide block, the transverse guide block is movably connected to the transverse guide rail, the transverse guide block is displaced left and right relative to the transverse guide rail, and the top end of the transverse guide block is connected to the bottom end of the extension frame.

[0019] When it is necessary to combine multiple LED advertising screens to form a larger display area, the motor must first be turned off to stop the device from rotating, and the second electric push rod must be controlled to extend so that the second electric push rod is engaged with the positioning hole, and the first electric push rod must be controlled to descend to release the engagement between the first electric push rod and the limiting hole. At this time, the fourth electric push rod can be synchronously opened to push the movable plate forward, and the connecting rod will deflect accordingly, and the angle between the two connecting rods will increase accordingly. At the same time, a thrust is applied to the two lateral guide blocks, and the two lateral guide blocks are displaced relative to the lateral guide rails, that is, the two lateral guide blocks are driven relatively away from each other, and finally the two extension frames at the top are driven relatively away from each other, and a thrust is applied to the two magnets so that the two magnets are moved away from each other.

[0020] At the same time, the third electric push rod can be turned on synchronously, and the extension plate can be pushed forward. At this time, the extension frame can be pushed forward, that is, the two extension frames move forward while moving relatively away from each other. At this time, the flexible hinge can be opened until it turns into a straight line. At this time, multiple LED advertising screens can be arranged in sequence to complete the assembly process.

[0021] Through the deformation process of the flexible hinge, that is, when the flexible hinge forms a circle, multiple LED advertising screens can be displayed in rotation, and when the flexible hinge becomes a straight line, multiple LED advertising screens can be arranged in sequence, so that the device can switch between two states. When multiple LED advertising screens are arranged in sequence, combined display can be achieved, so that multiple LED advertising screens form a whole, which is used to display larger display content, avoiding the problem that traditional devices are difficult to achieve low-cost large-area display content display.

[0022] When multiple LED advertising screens form a complete display screen, the LED advertising screens can form a flat screen. At this time, the surfaces of multiple LED advertising screens can be wiped simultaneously by a wiping tool, and after wiping, the devices can be formed into a circular shape for rotating display, thus quickly completing the maintenance process.

[0023] By utilizing the two display states of the device, that is, when the device is in the flat display state, since multiple LED advertising screens are on the same plane, multiple LED advertising screens can be inspected and maintained at the same time, without the need to perform maintenance on multiple LED advertising screens separately on multiple planes. At the same time, after the maintenance is completed, it can be quickly switched to the rotating display state, which reduces maintenance costs and improves the practicability of the device.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The present invention arranges multiple LED advertising screens and arranges them in a circular shape, and cooperates with the first electric push rod and the adjustment component at the bottom and the flexible hinge so that when the flexible hinge forms a circle, the multiple LED advertising screens can form a circle, and the cooperation between the first electric push rod and the limiting hole can realize the rapid rotation display of the multiple LED advertising screens, and a single LED advertising screen can display separate content. Through the rotation display of multiple LED advertising screens, different advertising information at various angles can be synchronously displayed, avoiding the problem that the traditional device has a single display content and a small observation range, thereby improving the advertising dissemination effect.

[0026] 2. The present invention realizes the rotational display of multiple LED advertising screens through the deformation process of the flexible hinge, that is, when the flexible hinge forms a circle, and when the flexible hinge becomes a straight line, multiple LED advertising screens can be arranged in sequence, so that the device can switch between two states. When multiple LED advertising screens are arranged in sequence, combined display can be achieved, so that multiple LED advertising screens form a whole, which is used to display larger display content, avoiding the problem that traditional devices are difficult to achieve low-cost large-area display content.

[0027] 3. The present invention utilizes two display states of the device, that is, when the device is in a flat display state, since multiple LED advertising screens are on the same plane, multiple LED advertising screens can be inspected and maintained at the same time, without the need to perform maintenance on multiple LED advertising screens separately on multiple planes. At the same time, after the maintenance is completed, it can be quickly switched to a rotating display state, which reduces maintenance costs and improves the practicability of the device.

[0039] In the initial state, multiple LED advertising screens 1 are arranged at equal angles around the outer side of the flexible hinge 3 to form a circular structure. At this time, the device is a rotary advertising device. If the device needs to be combined, multiple LED advertising screens 1 can be arranged in sequence to form a flat plate to meet different needs.

[0040] like Figure 2 and Figure 3 as well as Figure 4 and Figure 5 As shown, a motor 10 is fixedly installed at the bottom end of the extended machine base 9, a transmission disk 8 is fixedly installed at the output end of the motor 10, and a limiting hole 11 is provided at an equal angle at the bottom end of the transmission disk 8 near the outer side surface, and a first electric push rod 7 is fixedly installed at an equal angle at the top end of the flexible hinge 3. The number of the first electric push rods 7 is the same as the number of the limiting holes 11, and the top end of the first electric push rod 7 is adapted to the limiting hole 11. When the LED advertising screen 1 is formed into a circle, the output end of the first electric push rod 7 is movably connected to the limiting hole 11. When the LED advertising screen 1 is in a pre-assembly state, the top end of the first electric push rod 7 is disengaged from the inside of the limiting hole 11, and the top end of the second electric push rod 13 is inserted into the inside of the positioning hole 6 to complete the connection.

[0041] Embodiment: When the device needs to be formed into a circle for convenient observation at various angles, the adjustment component 14 can be restored to the initial state. At this time, the flexible hinge 3 can form a circle, and the magnets 4 at both ends are attracted to each other. At this time, the flexible hinge 3 can drive the multiple LED advertising screens 1 to move through the mounting rod 5 on the outer side until the multiple LED advertising screens 1 form a circular structure. At this time, the second electric push rod 13 can be controlled to shorten, and the second electric push rod 13 can be separated from the positioning hole 6, and the locking process between the second electric push rod 13 and the positioning hole 6 is released;

[0042] When the LED advertising screen 1 and the flexible hinge 3 return to their initial state, the multiple first electric push rods 7 can be turned on and controlled to extend synchronously until the top ends of the first electric push rods 7 are completely inserted into the limiting holes 11. At this time, the assembly between the first electric push rods 7 and the limiting holes 11 can be completed, and the transmission disk 8 can be driven to rotate by turning on the motor 10. At this time, the multiple first electric push rods 7 can be driven to rotate circumferentially, and finally the flexible hinge 3 can be driven to rotate. At this time, the multiple LED advertising screens 1 will move circumferentially accordingly to complete the rotation display process.

[0043] By setting up multiple LED advertising screens 1 and setting them in a circular shape, and coordinating the first electric push rod 7 and the adjustment component 14 at the bottom and the flexible hinge 3, when the flexible hinge 3 forms a circle, the multiple LED advertising screens 1 can be surrounded by a circle, and the cooperation between the first electric push rod 7 and the limiting hole 11 can realize the rapid rotation display of the multiple LED advertising screens 1, and a single LED advertising screen 1 can display separate content. Through the rotation display of multiple LED advertising screens 1, different advertising information at different angles can be synchronously displayed, avoiding the problem of single display content and small observation range of traditional devices, thereby improving the advertising dissemination effect.

[0044] like Figure 2 and Figure 6 as well as Figure 7 and Figure 8 As shown, the adjustment component 14 includes a transverse guide rail 141, a longitudinal guide rail 142 is fixedly installed at the rear end of the transverse guide rail 141, the transverse guide rail 141 and the longitudinal guide rail 142 are perpendicular to each other, an extension plate 143 is fixedly installed at the bottom end of the transverse guide rail 141, and the adjustment component 14 also includes a fixed plate 145, one end of the fixed plate 145 is fixedly connected to a third electric push rod 144, the output end of the third electric push rod 144 is connected to the extension plate 143, a fourth electric push rod 146 is fixedly sleeved at a position near the top of the fixed plate 145, the bottom end of the fixed plate 145 is connected to the top of the base 2, the output end of the fourth electric push rod 146 is fixedly connected to a movable plate 147, the top of the movable plate 147 is fixedly connected to a longitudinal guide block 1412, and the movable plate 147 is longitudinally The guide block 1412 is movably connected to the longitudinal guide rail 142, and the movable plate 147 is displaced forward and backward relative to the longitudinal guide rail 142. The first mounting seat 148 is installed on both sides of the left and right sides of the end of the movable plate 147 away from the fourth electric push rod 146. The end of the first mounting seat 148 away from the movable plate 147 is movably connected to the connecting rod 1410 through a rotating shaft, and the end of the connecting rod 1410 away from the first mounting seat 148 is movably connected to the second mounting seat 149 through a rotating shaft. The end of the second mounting seat 149 away from the connecting rod 1410 is fixedly connected to a transverse guide block 1411, which is movably connected to the transverse guide rail 141. The transverse guide block 1411 is displaced left and right relative to the transverse guide rail 141, and the top of the transverse guide block 1411 is connected to the bottom end of the extension frame 12.

[0045] Embodiment: When it is necessary to combine multiple LED advertising screens 1 to form a larger display area, the motor 10 must be turned off first to stop the device from rotating, and the second electric push rod 13 must be controlled to extend so that the second electric push rod 13 is engaged with the positioning hole 6, and the first electric push rod 7 is controlled to descend to release the engagement between the first electric push rod 7 and the limiting hole 11. At this time, the fourth electric push rod 146 can be opened synchronously to push the movable plate 147 forward. At this time, the connecting rod 1410 is deflected, and the angle between the two connecting rods 1410 increases. At the same time, a thrust is applied to the two lateral guide blocks 1411, and the two lateral guide blocks 1411 are displaced relative to the lateral guide rail 141, that is, the two lateral guide blocks 1411 are driven to move relatively away from each other, and finally the two extension frames 12 at the top are driven to move relatively away from each other, and a thrust is applied to the two magnets 4 so that the two magnets 4 move away from each other.

[0046] At the same time, the third electric push rod 144 can be turned on synchronously, and the extension plate 143 can be pushed forward. At this time, the extension frame 12 can be pushed forward, that is, the two extension frames 12 move forward while moving relatively away from each other. At this time, the flexible hinge 3 can be opened until it is transformed into a straight line. At this time, multiple LED advertising screens 1 can be arranged in sequence to complete the assembly process.

[0047] Through the deformation process of the flexible hinge 3, that is, when the flexible hinge 3 forms a circle, the rotation display of multiple LED advertising screens 1 can be realized, and when the flexible hinge 3 becomes a straight line, the multiple LED advertising screens 1 can be arranged in sequence, and the device can be switched between two states. When the multiple LED advertising screens 1 are arranged in sequence, a combined display can be achieved, so that the multiple LED advertising screens 1 form a whole for displaying larger display content, avoiding the problem that traditional devices are difficult to achieve low-cost large-area display content display.

[0048] When multiple LED advertising screens 1 form a complete display screen, the LED advertising screens 1 can form a flat screen. At this time, the surfaces of multiple LED advertising screens 1 can be wiped simultaneously by a wiping tool, and after wiping, the devices can be formed into a circular shape for rotating display, thereby quickly completing the maintenance process.

[0049] By utilizing the two display states of the device, that is, when the device is in the flat display state, since multiple LED advertising screens 1 are on the same plane, multiple LED advertising screens 1 can be inspected and maintained at the same time, without having to perform maintenance processes on multiple LED advertising screens 1 separately on multiple planes. At the same time, after the maintenance is completed, it can be quickly switched to the rotating display state, which reduces maintenance costs and improves the practicability of the device.

[0050] Working principle and usage process:

[0051] In the initial state, multiple LED advertising screens 1 are evenly angled around the outer side of the flexible hinge 3 to form a circular structure. At this time, the device is a rotary advertising device. If the device needs to be combined, multiple LED advertising screens 1 can be arranged in sequence to form a flat plate to meet different needs.

[0052] When the device needs to be formed into a circle for convenient observation at various angles, the adjustment component 14 can be restored to the initial state. At this time, the flexible hinge 3 can form a circle, and the magnets 4 at both ends are attracted to each other. At this time, the flexible hinge 3 can drive the multiple LED advertising screens 1 to move through the mounting rods 5 on the outer side until the multiple LED advertising screens 1 form a circular structure. At this time, the second electric push rod 13 can be controlled to shorten, and the second electric push rod 13 can be separated from the positioning hole 6, and the locking process between the second electric push rod 13 and the positioning hole 6 is released;

[0053] When the LED advertising screen 1 and the flexible hinge 3 return to their initial state, the multiple first electric push rods 7 can be turned on and controlled to extend synchronously until the top ends of the first electric push rods 7 are all inserted into the limiting holes 11. At this time, the assembly between the first electric push rods 7 and the limiting holes 11 can be completed, and the transmission disk 8 can be driven to rotate by turning on the motor 10. At this time, the multiple first electric push rods 7 can be driven to rotate circumferentially, and finally the flexible hinge 3 can be driven to rotate. At this time, the multiple LED advertising screens 1 move circumferentially accordingly, completing the rotation display process;

[0054] When it is necessary to combine multiple LED advertising screens 1 to form a larger display area, the motor 10 must be turned off first to stop the device from rotating, and the second electric push rod 13 must be controlled to extend so that the second electric push rod 13 is engaged with the positioning hole 6, and the first electric push rod 7 is controlled to descend to release the engagement between the first electric push rod 7 and the limiting hole 11. At this time, the fourth electric push rod 146 can be opened synchronously to push the movable plate 147 forward. At this time, the connecting rod 1410 is deflected, and the angle between the two connecting rods 1410 increases. At the same time, a thrust is applied to the two lateral guide blocks 1411, and the two lateral guide blocks 1411 are displaced relative to the lateral guide rail 141, that is, the two lateral guide blocks 1411 are relatively moved away, and finally the two extension frames 12 at the top are relatively moved away, and a thrust is applied to the two magnets 4 so that the two magnets 4 are moved away from each other.

[0055] At the same time, the third electric push rod 144 can be turned on synchronously, and the extension plate 143 can be pushed forward. At this time, the extension frame 12 can be pushed forward, that is, the two extension frames 12 move forward while moving relatively away from each other. At this time, the flexible hinge 3 can be opened until it is transformed into a straight line. At this time, multiple LED advertising screens 1 can be arranged in sequence to complete the assembly process.
