Description

Technical Field

[0001] This invention relates to a display screen mounting bracket, and more particularly to a display screen mounting bracket with automatic height adjustment. Background Technology

[0002] Display screens are being used more and more widely as a promotional tool. Currently, most display screens are placed on fixed frames when in use.

[0003] Patent application CN201210773 discloses a display screen holder shaped like an animal, plant, or cartoon character. The display screen is fixed within the spherical shell of the holder's head, face, chest, feet, back, top, and support, facing in various directions. This invention can increase the diversity, fun, and aesthetics of the display screen's overall appearance, thus changing the monotony of prior art display screen holders. While the aforementioned patent enables the placement of the display screen, it uses a fixed support structure with no height adjustment, making maintenance and replacement inconvenient.

[0004] Based on the deficiencies in the aforementioned patents, we propose an automatically height-adjustable display screen bracket that facilitates easy adjustment, maintenance, and replacement. Summary of the Invention

[0005] To overcome the shortcomings of the aforementioned patents, which use fixed support frames with non-adjustable height and inconvenient maintenance and replacement, this invention provides an automatically adjustable display screen mounting frame that allows for convenient height adjustment and easy maintenance and replacement.

[0006] The technical solution of this invention is:

[0007] An automatically height-adjustable display screen mounting bracket includes a support column, a rubber base, a placement back plate, a rotating base, a positioning bracket, a fixing screw, and a positioning base. The rubber base is fixedly connected to the lower part of the support column, and a positioning base is placed on the top of the support column. A rotating base is rotatably connected to the upper part of the positioning base, and a fixing screw is threadedly connected to the upper part of the rotating base. A positioning bracket is rotatably connected to the middle of the fixing screw. The front side of the positioning bracket is bolted to the placement back plate for placing the display screen. The bracket also includes a lifting mechanism and a buffer mechanism. The support column is equipped with a lifting mechanism for adjusting the height, which is fixedly connected to the positioning base. The placement back plate is equipped with a buffer mechanism for cushioning the display screen.

[0008] As a further preferred embodiment, the lifting mechanism includes a lifting column, a servo motor, and a positioning screw. The servo motor is fixedly connected to the lower part of the supporting column, and the positioning screw is connected to the output shaft of the servo motor. The lifting column is slidably connected inside the supporting column, and the lifting column is threadedly connected to the positioning screw. The lifting column is also fixedly connected to the positioning base block.

[0009] As a further preferred embodiment, the buffer mechanism includes a positioning plate, buffer blocks, a first reset guide, and a first reset spring. The first reset guide is fixedly connected to the lower middle part of the back plate, and the positioning plate is slidably connected to the first reset guide. Buffer blocks are symmetrically fixed to the left and right sides of the front side of the positioning plate, and the buffer blocks on both sides are slidably connected to the back plate. The first reset spring is symmetrically connected between the bottom of the positioning plate and the first reset guide.

[0010] As a further preferred embodiment, it also includes a clamping and fixing mechanism for clamping and limiting the display screen. The clamping and fixing mechanism includes positioning rods, clamping rubber plates, second reset guides, second reset springs, limiting bottom rods, limiting springs, hinged connecting rods, and fixing short rods. Two limiting bottom rods are slidably connected to the upper parts of the left and right sides of the back plate. A positioning rod is fixed between the left parts of the two limiting bottom rods on the left, and a positioning rod is also fixed between the right parts of the two limiting bottom rods on the right. The second reset guides are slidably connected to the positioning rods on both sides. Clamping rubber plates for clamping and limiting the display screen are fixed to the inner sides of the second reset guides on both sides. Second reset springs are symmetrically connected to the inner sides of the positioning rods on both sides and the second reset guides on both sides. Limiting springs are connected between the inner ends of the four limiting bottom rods and the interior of the back plate. Fixing short rods are fixed to the lower parts of the positioning rods on both sides. Hinged connecting rods are rotatably connected to the top of the positioning connecting plate on both sides.

[0011] As a further preferred embodiment, a support mechanism for support and protection is also included. This support mechanism comprises a lifting frame, support columns, a hinged roller frame, a torsion spring, a fixed base, buffer sliders, buffer springs, a drive gear plate, a reversing gear, and a positioning gear plate. The lifting frame is slidably connected to the support column. Buffer sliders are slidably connected to both the front and rear sides of the lifting frame. Two buffer springs connect each of the front and rear buffer sliders to the interior of the lifting frame. Support columns for support and protection are rotatably connected to the exterior of each of the front and rear buffer sliders. The lower part of each upright is rotatably connected to a hinged roller frame. Two torsion springs connect the hinged roller frames on the front and rear sides to the supporting uprights on the front and rear sides, respectively. A fixed base frame is fixedly connected to the lower part of the supporting column. The fixed base frame is slidably connected to the supporting uprights on the front and rear sides. Drive gear plates are embedded in the lower part of the front and rear sides of the lifting column. Reversing gears are rotatably connected to the middle of the front and rear sides of the supporting column. The reversing gears on the front and rear sides mesh with the drive gear plates on the front and rear sides, respectively. Positioning gear plates are fixedly connected to the front and rear sides of the lifting frame. The positioning gear plates on the front and rear sides mesh with the reversing gears on the front and rear sides, respectively.

[0012] As a further preferred embodiment, it also includes an angle positioning mechanism for positioning the rotating base block. The angle positioning mechanism includes a perforated base plate, a positioning short rod, and a positioning spring. The perforated base plate is fixed to the lower front side of the positioning base block, and the positioning short rod for limiting and fixing is slidably connected to the middle of the front part of the rotating base block. A positioning spring is connected between the inside of the rotating base block and the upper part of the positioning short rod.

[0013] The present invention has the following advantages:

[0014] 1. This invention places the display screen on the mounting back plate. If the height of the display screen needs to be adjusted, the servo motor is started. The positioning screw drives the positioning base block to move up and down through the lifting column. Then the mounting back plate also drives the display screen to move up and down. After the display screen is moved to the appropriate height, the servo motor is turned off. In this way, it is convenient for people to adjust the height of the display screen mounting bracket and to maintain and replace it easily.

[0015] 2. Under the action of the clamping and fixing mechanism, the second reset guides on the left and right sides move inward, respectively driving the clamping rubber plates on the left and right sides to move inward. The clamping rubber plates on the left and right sides move inward to clamp and limit the display screen. The second reset spring plays a buffering role. In this way, the display screen can be clamped and limited.

[0016] 3. Under the action of the support mechanism, the front and rear support poles swing outward to support the device. In this way, the display screen can be supported when it is raised, thus preventing it from tipping over. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0032] Example 1

[0033] An automatically height-adjustable display screen mounting bracket, such as Figures 1-4As shown, the device includes a support column 1, a rubber base frame 2, a back plate 3, a rotating base block 4, a positioning bracket 41, a fixing screw 42, a positioning base block 5, a lifting mechanism 6, and a buffer mechanism 7. The rubber base frame 2 is fixedly connected to the lower part of the support column 1. The positioning base block 5 is placed on the top of the support column 1. The rotating base block 4 is rotatably connected to the upper part of the positioning base block 5. The fixing screw 42 is threadedly connected to the upper part of the rotating base block 4. The positioning bracket 41 is rotatably connected to the middle of the fixing screw 42. The back plate 3 is connected to the front side of the positioning bracket 41 by bolts. The back plate 3 can be used to place the display screen. The support column 1 is equipped with a lifting mechanism 6, which can adjust the height of the display screen. The lifting mechanism 6 is fixedly connected to the positioning base block 5. The back plate 3 is equipped with a buffer mechanism 7. When the display screen is placed on the back plate 3, the buffer mechanism 7 can buffer the display screen.

[0034] like Figure 2 and Figure 3 As shown, the lifting mechanism 6 includes a lifting column 61, a servo motor 62, and a positioning screw 63. The servo motor 62 is fixedly connected to the lower part of the support column 1. The positioning screw 63 is connected to the output shaft of the servo motor 62. The lifting column 61 is slidably connected inside the support column 1. The lifting column 61 and the positioning screw 63 are threadedly connected. The lifting column 61 is fixedly connected to the positioning base block 5.

[0035] like Figure 2 and Figure 4 As shown, the buffer mechanism 7 includes a positioning plate 71, a buffer block 72, a first reset guide 73, and a first reset spring 74. The first reset guide 73 is fixedly connected to the lower middle part of the back plate 3. The positioning plate 71 is slidably connected to the first reset guide 73. The buffer blocks 72 are symmetrically fixed to the left and right sides of the front side of the positioning plate 71. The buffer blocks 72 on both sides are slidably connected to the back plate 3. The first reset spring 74 is symmetrically connected between the bottom of the positioning plate 71 and the first reset guide 73.

[0036] First, the operator adjusts the backplate 3 to a suitable angle by using the positioning bracket 41 to swing it back and forth. Then, the operator tightens the positioning bracket 41 by turning the fixing screw 42. The operator then rotates the backplate 3 to a suitable direction as needed. Next, the display screen is placed on the backplate 3, and the display screen contacts the left and right side buffer blocks 72. Due to gravity, the display screen causes the left and right side buffer blocks 72 to move downwards. This downward movement of the buffer blocks 72 causes the positioning bracket 71 to move downwards, compressing the first return spring 74. If the display screen height needs to be adjusted upwards, the servo motor 62 is started in reverse. The reverse rotation of the servo motor 62 causes the positioning screw 63 to reverse, which in turn causes the lifting column 61 to move upwards. The upward movement of the lifting column 61 then causes the positioning base block 5 to move upwards. The positioning base 5 moves upward, causing the rotating base 4 to move upward. The rotating base 4 moves upward, causing the placement back plate 3 to move upward. The placement back plate 3 moves upward, causing the display screen to move upward. After the display screen moves upward to a suitable height, the servo motor 62 can be turned off. Similarly, if the display screen height needs to be adjusted downward, the servo motor 62 is started to rotate forward. The positioning screw 63 rotates forward, causing the lifting column 61 to move downward. The placement back plate 3 also causes the display screen to move downward and reset. After the display screen moves downward to a suitable height, the servo motor 62 can be turned off. When there is no need to view the display screen, the display screen is removed from the placement back plate 3. The display screen is separated from the left and right side buffer rubber blocks 72. Due to the action of the first reset spring 74, the positioning connecting plate 71 causes the left and right side buffer rubber blocks 72 to move upward and reset.

[0037] Example 2

[0038] Based on Example 1, such as Figures 5-7 As shown, it also includes a clamping and fixing mechanism 8, which includes a positioning rod 81, a clamping rubber plate 82, a second reset guide 83, a second reset spring 84, a limiting bottom rod 85, a limiting spring 86, a hinged connecting rod 87, and a fixing short rod 88. Two limiting bottom rods 85 are slidably connected to the upper parts of both sides of the back plate 3. A positioning rod 81 is fixed between the left parts of the two limiting bottom rods 85 on the left, and a positioning rod 81 is also fixed between the right parts of the two limiting bottom rods 85 on the right. A second reset guide 84 is slidably connected to the positioning rods 81 on both sides. Positioning guide 83, clamping rubber plates 82 are fixed to the inner sides of the second reset guide 83 on both sides, and the clamping rubber plates 82 can clamp and limit the display screen. The inner sides of the positioning uprights 81 on both sides are symmetrically connected to the second reset guides 83 on both sides. The inner ends of the four limiting bottom rods 85 are connected to the inside of the placement back plate 3 with limiting springs 86. The lower part of the positioning uprights 81 on both sides is fixed with a fixing short rod 88. The fixing short rods 88 on both sides are rotatably connected to the top of the positioning connecting plate 71 with a hinged connecting rod 87.

[0039] like Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, it also includes a support mechanism 9, which includes a lifting frame 91, a support rod 92, a hinged roller frame 93, a torsion spring 94, a fixed base frame 95, a buffer slider 96, a buffer spring 97, a drive gear plate 98, a reversing gear 99, and a positioning gear plate 910. The lifting frame 91 is slidably connected to the support column 1. Buffer sliders 96 are slidably connected to both the front and rear sides of the lifting frame 91. Two buffer springs 97 are connected between each buffer slider 96 and the interior of the lifting frame 91. The support rod 92 is rotatably connected to the exterior of each buffer slider 96. The support rod 92 can support and protect the device to prevent tipping. Both sides of the support column 92 are rotatably connected to the lower part of the hinged roller frame 93. The front and rear hinged roller frames 93 are respectively connected to the front and rear support columns 92 with two torsion springs 94. The lower part of the support column 1 is fixedly connected to the fixed base frame 95, which is slidably connected to the front and rear support columns 92. The lower parts of the front and rear sides of the lifting column 61 are embedded with drive gear plates 98. The middle parts of the front and rear sides of the support column 1 are rotatably connected to reversing gears 99. The reversing gears 99 on the front and rear sides respectively mesh with the front and rear drive gear plates 98. The lifting frame 91 is fixedly connected to the front and rear sides of the positioning gear plate 910. The positioning gear plate 910 on the front and rear sides respectively mesh with the front and rear reversing gears 99.

[0040] When the display screen is placed inside the back panel 3, it comes into contact with the left and right side buffer blocks 72. Due to gravity, the display screen causes the left and right side buffer blocks 72 to move downwards. The downward movement of the left and right side buffer blocks 72 causes the positioning connecting plate 71 to move downwards, compressing the first return spring 74. The downward movement of the positioning connecting plate 71 causes the left and right side fixed short rods 88 to move inwards via the left and right side hinge connecting rods 87. The inward movement of the left and right side fixed short rods 88 causes the left and right side positioning upright rods 81 to move inwards, compressing the limit spring 86. The inward movement of the left and right side positioning upright rods 81 causes the left and right side second reset guides 83 to move inwards. The inward movement of the clamping plates 82 on both sides causes them to move inward, thus clamping and limiting the display screen. The second return spring 84 acts as a buffer. When the display screen is not needed, it can be removed from the back plate 3, and the display screen will detach from the buffer blocks 72 on both sides. Due to the action of the first return spring 74, the positioning connecting plate 71 drives the left and right fixed short rods 88 on both sides to move outward and reset through the hinge connecting rods 87 on both sides. Due to the action of the limiting spring 86, the left and right positioning upright rods 81 drive the left and right fixed short rods 88 on both sides to move outward and reset, and the clamping plates 82 on both sides also move outward and reset. In this way, the display screen can be easily clamped and limited.

[0041] When adjusting the display screen height upwards, the servo motor 62 is activated in reverse, causing the lifting column 61 to move upwards, which in turn moves the front and rear drive gear plates 98 upwards. The upward movement of the front and rear drive gear plates 98 in turn rotates the front and rear reversing gears 99, which in turn moves the front and rear positioning gear plates 910 downwards. The downward movement of the front and rear positioning gear plates 910 in turn moves the lifting frame 91 downwards, which in turn moves the front and rear support columns 92 downwards. At the same time, the front and rear hinged roller frames 93 cause the front and rear support columns 92 to swing outwards. The torsion spring 94 acts as a buffer. After the display screen is moved upwards to the appropriate height, the servo motor 62 is turned off. Thus, the outward swing of the front and rear support columns 92 supports the device. Similarly, if the display screen height needs to be adjusted downwards, the servo motor 62 is activated in forwards, and the front and rear support columns 92 swing inwards to reset. After the display screen is moved downwards to the appropriate height, the servo motor 62 is turned off. In this way, the display screen can be supported when raised, preventing it from tipping over.

[0042] Example 3

[0043] Based on Examples 1 and 2, such as Figure 5 and Figure 13As shown, it also includes an angle positioning mechanism 10 for positioning the rotating base block 4. The angle positioning mechanism 10 includes an open base plate 101, a positioning short rod 102 and a positioning spring 103. The open base plate 101 is fixed to the lower front side of the positioning base block 5. The positioning short rod 102 is slidably connected to the middle of the front part of the rotating base block 4. The positioning short rod 102 can realize the positioning of the rotating base block 4. The positioning spring 103 is connected between the inside of the rotating base block 4 and the upper part of the positioning short rod 102.

[0044] When people rotate the positioning base block 5 to place the back plate 3, the rotation of the positioning base block 5 drives the positioning short rod 102 to rotate. Due to the action of the positioning spring 103, the positioning short rod 102 rotates and continuously inserts into the hole of the perforated base plate 101. After the back plate 3 is rotated to a suitable angle, the positioning short rod 102 limits the rotating base block 4, and the back plate 3 is also limited. In this way, it is convenient to position the back plate 3.

[0045] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
