[0001] The present invention relates to the technical field of fixed brackets, and in particular to an advertising machine bracket which is easy to fix. Background Art

[0002] An advertising machine is a type of electronic display device used to display information and commercial advertisements in public places. It is more common in commercial locations due to the comprehensiveness and applicability of information display. The advertising machine stand is a fixed device used to support the advertising machine at a fixed point. The stability that the advertising machine stand can provide to the advertising machine determines the flexibility that the advertising machine can meet.

[0003] The current advertising machine brackets are rather troublesome in terms of disassembly and assembly of the advertising machine. The fixing of the advertising machine usually requires many steps.

At this time, the advertising machine body can be easily removed as a whole, further saving the output of disassembly and assembly labor.

[0021] The present invention arranges a storage mechanism at a position near the placement plate at the bottom of the rain shield. When the pressure plate on the top of the placement plate moves to the side of the push wheel, the electric push rod at the bottom of the rain shield can drive the push wheel to move through the U-shaped connecting rod until the push wheel pushes the surface of the pressure plate, and the pressure plate is fixed to the placement plate. In this way, the placement plate will also rotate with the shaft hole of the transmission block as the center of the circle until the placement plate drives the main body of the advertising machine as a whole to be flush with the bottom surface of the rain shield. In this state, the force area of ​​the wind can be effectively reduced, thereby improving the wind resistance of the advertising machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0032] refer to Figure 1-Figure 7 , including an outer frame as a whole consisting of a base 1, a column 2 and a rain shield 3, the column 2 is fixed between the base 1 and the rain shield 3, a transmission assembly 4 is arranged in the base 1, the transmission assembly 4 includes an active motor 41, two sets of screws 42 and a transmission block 43, the lower parts of the two sets of screws 42 are connected to the output shaft of the active motor 41 through a transmission belt, the active motor 41 is fixed in the base 1, the transmission block 43 is threadedly connected to the surface of the screw 42, the transmission block 43 is slidably arranged in the column 2, one side of the transmission block 43 is movably connected to the support plate assembly 5, and the transmission block 43 drives the support plate assembly 5 to move up and down on the side of the column 2;

[0033] Two sets of side clamping plates 64 are provided on one side of the support plate assembly 5. The two sets of side clamping plates 64 are respectively located on the left and right sides of the surface of the support plate assembly 5. The front side of the support plate assembly 5 is clamped with the advertising machine body 7 by the two sets of side clamping plates 64.

[0034] A disassembly and assembly platform 8 and a storage mechanism 9 are respectively provided at the top of the base 1 and the bottom of the rain shield 3 near the column 2 , and the placement plate 51 is rotatably connected to the transmission block 43 through the disassembly and assembly platform 8 and the storage mechanism 9 .

[0035] In this embodiment, the active motor 41 can directly drive the two sets of screws 42 to rotate inside the column 2 through the transmission belt after being driven inside the base 1, and the transmission block 43 is threadedly connected to the screw 42. At this time, the transmission block 43 on the surface of the screw 42 is restricted by the sliding of the column 2, so that the transmission block 43 as a whole moves up and down on the surface of the screw 42. One side of the transmission block 43 is directly connected to the placement plate 51 in the support plate assembly 5 through the side plate, driving the placement plate 51 to move up and down synchronously;

[0036] During this process, the upward movement of the placement plate 51 will drive the advertising machine body 7 as a whole to approach the storage mechanism 9 under the rain shield 3 until the placement plate 51 contacts the storage mechanism 9. Under the continuous transmission operation, the placement plate 51 is overturned by force until the placement plate 51 is flush with the bottom surface of the rain shield 3. At this time, the advertising machine body 7 reduces the overall force area, thereby improving the wind resistance effect, and is suitable for storage settings in strong wind weather;

[0037] During the downward movement of the placement plate 51, it will contact the disassembly platform 8. At this time, under the guidance of the disassembly platform 8, the placement plate 51 and the transmission block 43 rotate to align the placement plate 51 with the disassembly platform 8, so that the self-locking fixing mechanism 6 between the placement plate 51 and the advertising machine body 7 will release the clamping of the advertising machine body 7, which is convenient for the disassembly operation of the advertising machine body 7.

[0038] When the placement plate 51 is normally vertical to the base 1, the self-locking fixing mechanism 6 will be driven by the advertising machine body 7 so that the side clamping plates 64 automatically clamp the two sides of the advertising machine body 7. In this way, the advertising machine body 7 can stably drive the side clamping plates 64 to fix the advertising machine body 7 under the action of its own gravity, so that the stability is strong and the effect of quick installation and removal is achieved.

[0039] refer to Figure 3 and Figure 6 The support plate assembly 5 includes a placement plate 51 and two sets of anti-sway side plates 52. The anti-sway side plates 52 are fixed on one side of the placement plate 51. The placement plate 51 is movably connected to the transmission block 43. A limiting slide rail 53 is set on the side of the column 2 near the anti-sway side plate 52. The anti-sway side plate 52 is slidably connected to the limiting slide rail 53 through a sliding pin.

[0040] In the present embodiment, the placement plate 51 achieves a stabilizing effect through the anti-sway side plate 52 and the limiting slide rail 53 on the side of the column 2. First, the movable connection position between the transmission block 43 and the placement plate 51 is above the back of the placement plate 51. During normal use, in order to prevent the lateral wind from blowing the placement plate 51 to shake as a whole, when the placement plate 51 is normally vertical to the base 1, the anti-sway side plate 52 will be limited by the sliding pin and the limiting slide rail 53. The limiting slide rail 53 and the anti-sway side plate 52 provide an overall stabilizing effect for the placement plate 51 to prevent the placement plate 51 from shaking.

[0041] refer to Figure 3 , Figure 4 and Figure 5 A self-locking fixing mechanism 6 is provided between the placement plate 51 and the advertising machine body 7. The self-locking fixing mechanism 6 includes an arch frame 61 and two sets of side clamping plates 64. The arch frame 61 slides on the surface of the placement plate 51. A slide column 67 is also fixed to the position of the placement plate 51 near the arch frame 61. The slide column 67 and the arch frame 61 telescopically slide. A spring member 68 is sleeved on the surface of the slide column 67. The arch frame 61 is elastically connected to the placement plate 51 through the spring member 68. The two sides of the bottom of the arch frame 61 are slidably connected to the movable slide grooves 66 provided on the surface of the first lever plate 62 through sliding pins. Two sets of movable slide grooves 66 are provided on the surface of the first lever plate 62. The two sets of movable slide grooves 66 are respectively located on the left and right sides of the first lever plate 62. The position of the first lever plate 62 near one side of the arch frame 61 is rotatably provided on the surface of the placement plate 51 through a pin hole. Two groups of second lever plates 63 are movably arranged below the placement plate 51. The two groups of second lever plates 63 are staggered and the staggered positions are movable with each other through the shaft holes. The top of the second lever plate 63 is slidably connected to the movable slide groove 66 on the surface of the first lever plate 62 away from the side of the arch frame 61 through the pin hole, and the bottom of the second lever plate 63 is movably connected to the side clamping plate 64 through the shaft pin. A limiting slide groove 65 is opened at the upper position of the placement plate 51 near the side clamping plate 64. The top of the side clamping plate 64 is slidably connected to the limiting slide groove 65 through a limit slider. Two groups of supporting protrusions 69 are also fixedly arranged on the surface of the arch frame 61. The back of the advertising machine body 7 is in contact with the supporting protrusion 69 through the clamping protrusion.

[0042] In this embodiment, the advertising machine body 7 provides a downward pressure to the supporting protrusion 69 through the card protrusion on the back under the action of gravity, and the supporting protrusion 69 is fixed to the surface of the arch frame 61, so that the arch frame 61 pushes the first lever plate 62 through the shaft pin below under the action of gravity, and the shaft pin slides in the movable slide groove 66 opened on the surface of the first lever plate 62, and the first lever plate 62 is rotatably connected to the surface of the placement plate 51 through the shaft pin, so that under the downward pressure of the arch frame 61, the first lever plate 62 rotates as a whole, and the rotation center position is the shaft pin position close to one side of the arch frame 61, so that the first lever plate 62 is like a lever as a whole, which will lift the movable slide groove 66 on the other side, and the movable slide groove 66 on the other side will lift the top of the second lever plate 63 through the shaft pin at this time, so that the two sets of second lever plates 63 swing as a whole with the mutually staggered positions as the center of the circle;

[0043] At this time, driven by the second lever plate 63, the side clamping plates 64 are forced to align with each other, and the expansion of the side clamping plates 64 is restricted by the limiting slide groove 65, so that the movement direction of the side clamping plates 64 is stabilized. In this way, the two sets of side clamping plates 64 can clamp the two sides of the advertising machine body 7 during the alignment process, thereby achieving stable operation. The overall installation does not rely on the use of workpieces such as bolts, making it easier to disassemble and assemble the advertising machine body 7 later.

[0044] When the arch frame 61 is pressed downward by the supporting protrusion 69, the arch frame 61 itself is restricted by the sliding column 67, so that it moves downward stably. In this process, the spring member 68 is also compressed. The existence of the spring member 68 facilitates the subsequent lifting and resetting of the arch frame 61, and at the same time provides a certain energy absorption effect for the advertising machine body 7 and the mounting plate 51 as a whole, so that it also has a certain impact resistance.

[0045] refer to Figure 2 and Figure 6 The disassembly and assembly platform 8 includes an inclined platform 81 and a bracket 82. The bracket 82 is fixed to one side of the inclined platform 81. The inclined platform 81 is fixed to the top of the base 1 at a certain angle. The bracket 82 and the inclined platform 81 are fixed at a right angle. The bottom of the placement plate 51 is movably connected to the abutment roller 83 through a shaft rod. The abutment roller 83 is located directly above the inclined platform 81.

[0046] In the present embodiment, during the process of the transmission block 43 driving the placement plate 51 to move downward as a whole, the resistance roller 83 below the placement plate 51 will first fit with the surface of the inclined platform 81. At this time, the transmission block 43 continues to drive the placement plate 51 to descend. During the descent, the placement plate 51 is acted upon by the reaction force of the resistance roller 83 to realize the movement between itself and the transmission block 43, and finally realizes the flush operation between the placement plate 51 as a whole and the inclined platform 81. During this process, the bracket 82 will also lift the bottom of the advertising machine body 7. At this time, the force of the advertising machine body 7 on the supporting protrusion 69 will be reduced, thereby facilitating the removal of the advertising machine body 7 for disassembly.

[0047] refer to Figure 3 and Figure 7 The storage mechanism 9 includes two sets of electric push rods 91 and push wheels 93. The two sets of electric push rods 91 are respectively fixed to the left and right sides of the bottom of the rain shield 3. The output end of the electric push rod 91 is fixedly connected to the push wheel 93 through a U-shaped connecting rod 92. The push wheel 93 drives the pressure plate 94 to swing around the rotation axis of the transmission block 43 and the placement plate 51. The pressure plate 94 is fixed on the top of the placement plate 51. When the pressure plate 94 and the push wheel 93 are in contact with each other, the limit slide rail 53 and the anti-sway side plate 52 are separated from each other.

[0048] In the present embodiment, when the placement plate 51 drives the advertising machine body 7 to rise as a whole, the pressure plate 94 on the top of the placement plate 51 will first rise to one side of the push wheel 93. At this time, the electric push rod 91 at the bottom of the rain shield 3 is driven, and the electric push rod 91 can drive the push wheel 93 to move toward the pressure plate 94 through the U-shaped connecting rod 92 until the push wheel 93 pushes the pressure plate 94. At this time, the pressure plate 94 and the placement plate 51 as a whole will be subject to the pushing force of the push wheel 93, so that the placement plate 51 as a whole swings with the movable part of the transmission block 43 as the center of the circle until the placement plate 51 and the advertising machine body 7 as a whole are flush with the bottom surface of the rain shield 3. At this time, the contact area between the advertising machine body 7 and the placement plate 51 and the wind force is reduced, thereby improving the overall wind resistance of the device.

[0049] Working principle: first drive the active motor 41 in the transmission assembly 4, the active motor 41 will drive the two sets of screws 42 to rotate through the transmission belt, and the transmission block 43 will move up and down inside the column 2 at this time, driving the placement plate 51 to fall to the position of the disassembly and assembly platform 8, at this time, the resistance roller 83 under the placement plate 51 will first fit with the surface of the inclined table 81, and the continuous movement will realize the rotation effect between the placement plate 51 as a whole and the transmission block 43 under the guidance of the inclined table 81, so that the placement plate 51 is flush with the inclined table 81 as a whole, at this time, the advertising machine body 7 is placed on the bracket 82 and flush with the placement plate 51, and the active motor 41 is driven in the reverse direction, and the placement plate 51 will gradually become perpendicular to the base 1 at this time. In this process, the force of the advertising machine body 7 will gradually act on the supporting protrusion 69 in the self-locking fixing mechanism 6, and The supporting protrusion 69 is fixed on the arch frame 61. At this time, the arch frame 61 will move downward on the surface of the placement plate 51 under the pressure. When the spring member 68 on the surface of the sliding column 67 is squeezed, the axle pin below the arch frame 61 will slide with the movable sliding groove 66 on the surface of the first lever plate 62. Since the first lever plate 62 rotates on the surface of the placement plate 51, under the pressure of the arch frame 61, the other end of the first lever plate 62 will drive the second lever plate 63 to swing upward through the movable sliding groove 66, and the lower part of the second lever plate 63 is connected to the side clamping plate 64. The side clamping plate 64 moves stably in opposite directions under the restriction of the limiting sliding groove 65 until the side clamping plate 64 clamps the two sides of the advertising machine body 7. At this time, the placement plate 51 is also perpendicular to the base 1, which can effectively ensure the stability of the advertising machine body 7.

[0050] When facing strong wind weather, the active motor 41 first drives the placement plate 51 and the advertising machine body 7 to move upward as a whole, until the pressure plate 94 on the top of the placement plate 51 rises to the side of the push wheel 93. At this time, the anti-sway side plate 52 is also separated from the limiting slide rail 53, and then the electric push rod 91 at the bottom of the rain shield 3 is driven to drive the push wheel 93 to move to one side through the U-shaped connecting rod 92, and the pressure plate 94 will be squeezed while moving. At this time, the placement plate 51 as a whole will swing again with the active part of the transmission block 43 as the center, thereby driving the placement plate 51 and the advertising machine body 7 to flip over as a whole, until the advertising machine body 7 is flush with the bottom surface of the rain shield 3, so that the contact area between the advertising machine body 7 and the wind is reduced, thereby improving the wind resistance effect.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
