Description

Technical Field

[0001] This invention relates to the field of home appliance technology, and in particular to a display device adjustment base. Background Technology

[0002] With the continuous development of science and technology, display devices generally refer to instruments with display functions. Common display devices include touch screens, LCD / LED displays, etc. LCD touch screen all-in-one machines, as intelligent devices integrating human-computer interaction and LCD display functions, have gradually become popular products in the market due to their high stability, low heat generation, good clarity, and simple operation. They are widely used in public information display places such as new product promotion exhibitions, hospitals, and libraries. However, traditional LCD touch screen all-in-one machines generally use fixed-height models, which cannot simultaneously meet the needs of users of different heights or different usage scenarios, thus limiting their applicability.

[0003] To achieve height adjustment and screen orientation switching, existing LCD touch screen all-in-one machines have a lifting mechanism on the back or side and a rotating mechanism on the back. Due to the machine's weight, locking mechanisms are required to maintain the height and rotate the machine to a specific angle. This necessitates unlocking the lifting mechanism before raising or lowering, a complex and inconvenient process. The rotating mechanism is also complex, with cumbersome locking and unlocking procedures, increasing the machine's weight and size, further hindering its usability. Furthermore, the rotating mechanism requires manufacturing multiple locking mechanisms to accommodate different machine weights, resulting in high manufacturing costs.

[0004] Therefore, it is necessary to research and develop an adjustment base for display devices (such as LCD touch screen all-in-one machines) so that the LCD touch screen all-in-one machine can be stopped at will during lifting and rotation, thereby improving the adjustment convenience of the LCD touch screen all-in-one machine and solving the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a display device adjustment base, which enables the LCD touch screen all-in-one machine to simultaneously achieve arbitrary stopping and lifting and rotation, thereby improving the adjustment convenience of the LCD touch screen all-in-one machine.

[0006] To achieve the above objectives, the present invention provides a display device adjustment base, the specific implementation of which is as follows:

[0007] A display device adjustment base, comprising:

[0008] support;

[0009] A mounting bracket is disposed on the support, and a groove is formed in the mounting bracket, with a through hole opened on the bottom of the groove;

[0010] A pneumatic spring is mounted on the mounting bracket, and at least one end of the pneumatic spring is connected to the bracket;

[0011] A rotating mechanism is rotatably mounted on the mounting frame;

[0012] The rotating mechanism includes a rotating disk connected to the display device, a rotating bushing on the rotating disk, the rotating bushing being rotatably inserted into the through hole, the end of the rotating bushing extending into the groove, the outer wall of the rotating bushing and the groove wall of the groove forming a first mounting groove, and a plurality of elastic gaskets sleeved on the rotating bushing being provided in the first mounting groove.

[0013] The rotating bushing has a pressing member at its end, which is embedded in the first mounting groove and the end of the pressing member presses against the elastic gasket.

[0014] This invention provides a display device adjustment base. Compared to existing technologies, it features a mounting bracket on a support frame, with a rotating disk on the mounting bracket for connecting to a liquid crystal touchscreen all-in-one machine. Firstly, by incorporating a pneumatic spring-driven lifting mechanism on the mounting bracket, the adjustable air pressure within the pneumatic spring allows for adjustment based on the weight of the liquid crystal touchscreen all-in-one machine. This balances the supporting force of the pneumatic spring on the liquid crystal touchscreen all-in-one machine with its weight, requiring an external force to disrupt this balance before lifting or lowering. Removing the external force stops the lifting or lowering, allowing the liquid crystal touchscreen all-in-one machine to be raised, lowered, and stopped arbitrarily within the stroke range of the pneumatic spring without the need for a locking mechanism, thus improving ease of lifting and lowering. Furthermore, it can adapt to liquid crystal touchscreen all-in-one machines with arbitrary counterweights by adjusting the air pressure within the pneumatic spring. Secondly, by incorporating a rotating bushing within the rotating disk, with its end extending into a groove in the mounting bracket, the system achieves a smooth transition between the rotating bushing and the rotating disk. The groove wall forms a first mounting groove. Multiple elastic pads are placed in the first mounting groove and fitted onto the rotating bushing. The elastic pads are pressed together by a pressing member, creating a frictional force between the elastic pads and the rotating bushing that prevents the rotating bushing from rotating. The magnitude of the frictional force is adjusted by changing the number of elastic pads to balance the weight of the LCD touch screen all-in-one machine. This means that switching between portrait and landscape modes requires applying a rotational force to the LCD touch screen all-in-one machine to disrupt the force balance. After the rotational force is removed, the LCD touch screen all-in-one machine stops at any rotation angle within the rotation stroke of the rotating mechanism without the need for rotation locking, improving the convenience of rotation. Furthermore, the number of elastic pads can be adjusted to accommodate LCD touch screen all-in-one machines with any counterweight, requiring only the same elastic pads to be manufactured, reducing production costs. It has the advantages of being easy to use, having a wide range of applications, and low manufacturing costs. It effectively enables the LCD touch screen all-in-one machine to simultaneously achieve arbitrary stopping and lifting and rotation, improving the adjustability of the LCD touch screen all-in-one machine.

[0015] In some embodiments, a limiting groove is formed in the rotating disk, and a limiting block is provided on the mounting frame. The limiting block is embedded in the limiting groove, and the limiting groove and the limiting block are in sliding engagement. By forming a limiting groove in the rotating disk and providing a limiting block embedded in the limiting groove on the mounting frame, the limiting engagement of the limiting groove and the limiting block enables the LCD touch screen all-in-one machine to rotate within the stroke range of the limiting groove. Furthermore, the guiding effect of the limiting groove and the limiting block improves the stability and accuracy of the rotation angle.

[0016] In some embodiments, the limiting groove and the limiting block are arranged in an annular shape. A first blocking wall and a second blocking wall are formed on the two end walls of the limiting groove, respectively. The first end of the limiting block engages with the first blocking wall, and the second end of the limiting block engages with the second blocking wall. By utilizing the first and second blocking walls in the limiting groove to abut against the first and second ends of the limiting block, respectively, the rotational travel of the rotating disk on the mounting bracket is limited, thereby limiting the rotation angle of the LCD touch screen all-in-one machine. Furthermore, the precise switching between portrait and landscape modes can be achieved based on the limiting action of the first and second blocking walls.

[0017] In some embodiments, a second mounting groove is provided on the rotating disk, which mates with the first mounting groove. One end of the rotating bushing is disposed in the second mounting groove, and the other end passes through the second mounting groove and the first mounting groove in sequence, extending into the groove body. By providing a second mounting groove on the rotating disk, which mates with the first mounting groove, the ease of assembling and disassembling the rotating bushing from the rotating disk is improved.

[0018] In some embodiments, a limiting step is formed on the side of the second mounting groove away from the mounting bracket. The rotating bushing includes an insertion section and a limiting section. The insertion section extends into the groove through the second mounting groove. The first mounting groove is formed between the groove wall of the groove and the outer wall of the insertion section. One end located at the connection between the limiting section and the insertion section abuts against the limiting step. By forming a limiting step on the side of the second mounting groove away from the mounting bracket, the rotating bushing is configured with an insertion section and a limiting section. The abutting engagement of the limiting section and the limiting step restricts the insertion stroke of the rotating bushing. When the limiting section and the limiting step abut, it can be determined that the rotating bushing is installed in place, thus improving the installation accuracy of the rotating bushing.

[0019] In some embodiments, a first positioning surface is formed on the wall of the second mounting groove, and a second positioning surface is formed on the insertion section and / or the limiting section, the second positioning surface engaging with the first positioning surface. By forming the first positioning surface on the wall of the second mounting groove and the second positioning surface on the outer wall of the insertion section and / or limiting section of the rotating bushing, the engagement of the first and second positioning surfaces prevents relative rotation between the rotating bushing and the rotating disk, thus avoiding a situation where the frictional force of the elastic gasket cannot act on the LCD touch screen all-in-one machine.

[0020] In some embodiments, the pneumatic spring is disposed on both sides of the mounting bracket, a first connecting block is provided at the bottom end of the pneumatic spring, and a first mounting block is provided on the bracket below the mounting bracket, the first connecting block being connected to the first mounting block. A second connecting block is provided at the top of the pneumatic spring, and the second connecting block is connected to the mounting bracket. By providing a first mounting block on the bracket that mates with the first connecting block at the bottom end of the pneumatic spring, the connection between the pneumatic spring and the bracket is achieved, allowing the mounting bracket to rise and fall on the bracket under the extension and retraction of the pneumatic spring.

[0021] In some embodiments, a plug-in protrusion is formed on the mounting bracket, and two opposing guide rods are provided on the mounting bracket. Both ends of the guide rods are inserted into and pass through the plug-in protrusion, extending to the outside of the mounting bracket and connecting with the support. A damping element is sleeved on the guide rod and inserted into the plug-in protrusion. By providing a plug-in protrusion on the mounting bracket, the two guide rods are fixed by the plug-in protrusion. The guide rods play a guiding role in the lifting and lowering of the mounting bracket and improve the lifting and lowering stability. The plug-in protrusion improves the connection stability and guiding stability of the guide rods. The damping element provides damping force for the lifting and lowering of the guide rods, improves the lifting and lowering feel of the LCD touch screen all-in-one machine, and is also used to cooperate with the supporting force of the pneumatic spring to achieve force balance with the gravity of the LCD touch screen all-in-one machine.

[0022] In some embodiments, two opposing receiving grooves are formed on the mounting bracket. A retaining member is provided within each receiving groove, with both ends of the retaining member abutting against the groove wall. Receiving grooves are formed at both ends of the retaining member. The damping member includes an insertion collar with a limiting flange formed at its end. The insertion collar is inserted into the insertion protrusion, and the limiting flange abuts against the groove wall and is received within the receiving groove. By providing a retaining member within the receiving groove, and with both ends of the retaining member abutting against the groove wall, forming receiving grooves at both ends of the retaining member, and the limiting flange of the damping member being received within the receiving groove, the damping member is prevented from detaching from the insertion protrusion when the mounting bracket is raised or lowered by the lifting mechanism.

[0023] In some embodiments, a second mounting block is provided on the bracket above the mounting frame. The top end of the guide rod is connected to the second mounting block, and the bottom end is connected to the first mounting block. Connecting the top end of the guide rod to the second mounting block and the bottom end to the first mounting block improves the stability of the guide rod's connection position.

[0024] The present invention provides a display device adjustment base. On one hand, by incorporating a pneumatic spring lifting mechanism on the mounting bracket, the adjustable air pressure within the pneumatic spring can be adjusted according to the weight of the LCD touchscreen all-in-one device. This balances the supporting force of the pneumatic spring on the LCD touchscreen all-in-one device with its weight, requiring an external force to disrupt this balance before lifting or lowering. Removing the external force stops the lifting or lowering. This allows the LCD touchscreen all-in-one device to be raised, lowered, and stopped arbitrarily within the stroke range of the pneumatic spring without the need for a locking mechanism, thus improving the convenience of lifting and lowering. Furthermore, it can adapt to LCD touchscreen all-in-one devices with arbitrary counterweights by adjusting the air pressure within the pneumatic spring.

[0025] On the other hand, by setting a rotating bushing inside the rotating disk, the end of the rotating bushing extends into the groove of the mounting bracket to form a first mounting groove with the groove wall. By setting multiple elastic pads in the first mounting groove and sleeved on the rotating bushing, and pressing the elastic pads with a pressing member, a frictional force is formed between the elastic pads and the rotating bushing to prevent the rotating bushing from rotating. The magnitude of the frictional force is adjusted by adjusting the number of elastic pads to balance the weight of the LCD touch screen all-in-one machine. This means that switching between portrait and landscape screens of the LCD touch screen all-in-one machine requires applying a rotational external force to disrupt the force balance. After the rotational external force is removed, the LCD touch screen all-in-one machine stops at any rotation angle within the rotation stroke of the rotating mechanism without the need for rotation locking, improving the convenience of rotation. Furthermore, the number of elastic pads can be adjusted to accommodate LCD touch screen all-in-one machines with any counterweight, and only the same elastic pads need to be manufactured, reducing production costs.

[0042] A display device adjustment base according to the present invention is described in conjunction with the accompanying drawings.

[0043] like Figure 1-8 As shown, the display device adjustment base includes a bracket 1, a mounting bracket 2 is provided on the side of the bracket 1, a lifting mechanism on the mounting bracket 2 drives the mounting bracket 2 to rise and fall on the bracket 1, so as to realize the height adjustment of the LCD touch screen all-in-one machine, and a rotatable rotation mechanism is provided on the mounting bracket 2 to drive the LCD touch screen all-in-one machine to rotate.

[0044] The rotating mechanism includes a rotating disk 41, which is rotatably mounted on the mounting frame 2 to connect to the LCD touch screen all-in-one machine and drive it to rotate.

[0045] Specifically, the rotating disk 41 is located on the side of the mounting frame 2 and rotates in cooperation with the mounting frame 2. A rotating bushing 42 is provided on the rotating disk 41, and the rotating bushing 42 rotates synchronously with the rotating disk 41 under the drive of the rotating disk 41. A groove 21 is provided on the mounting frame 2, and a through hole 22 is provided on the bottom of the groove 21 to penetrate the mounting frame 2. The end of the rotating bushing 42 passes through the through hole 22 and extends into the groove 21.

[0046] Furthermore, a second mounting groove 411 is provided on the rotating disk 41. The second mounting groove 411 cooperates with the through hole 22, and a limiting step 412 is formed on the second mounting groove 411. The rotating bushing 42 includes an insertion section 421 and a limiting section 422. The insertion section 421 is inserted into the second mounting groove 411, and the end of the insertion section 421 extends into the groove 21 through the through hole 22. At this time, the limiting section 422 is at least partially accommodated in the second mounting groove 411, and the axial inner side of the limiting section 422 abuts against the limiting step 412.

[0047] Furthermore, when the insertion segment 421 extends into the groove 21, a first mounting groove 23 is formed between the outer wall of the insertion segment 421 and the groove wall of the groove 21. Multiple elastic pads 43 are provided within the first mounting groove 23. The elastic pads 43 are stacked and sleeved on the insertion segment 421, and the elastic pads 43 abut against the bottom of the first mounting groove 23 (i.e., the bottom of the groove 21). The elastic pads 43 provide rotational friction resistance to prevent the rotating bushing 42 from rotating, thus providing a better rotational feel when the LCD touch screen all-in-one machine rotates. Under normal conditions, the rotational friction resistance generated by the elastic pad 43 is offset by the weight of the LCD touch screen all-in-one machine, allowing the LCD touch screen all-in-one machine to always remain in landscape or portrait mode without external rotational interference. This eliminates the need for a locking mechanism, reduces the structural complexity of the rotation mechanism, and improves the ease of switching between landscape and portrait modes by adjusting the rotation angle. Furthermore, the number of elastic pads 43 can be adjusted according to the counterweight of the LCD touch screen all-in-one machine, thereby adjusting the magnitude of the rotational friction resistance. This allows the rotation mechanism to be adapted to LCD touch screen all-in-one machines with any counterweight, reducing the manufacturing cost of the rotation mechanism.

[0048] Furthermore, a pressing member 44 is provided at the end of the insertion section 421. The pressing member 44 presses against the elastic gasket 43, and when the pressing member 44 is provided at the end of the insertion section 421, the pressing member 44 covers the groove 21.

[0049] Preferably, the pressing member 44 is provided with a plurality of disassembly and assembly holes 441 for inserting the rod of the disassembly and assembly tool, and the disassembly and assembly of the pressing member 44 and the rotating bushing 42 are realized by rotating the rod to drive the pressing member 44 to rotate.

[0050] Preferably, a first thread is provided at the end of the insertion section 421, and a second thread that mates with the first thread is provided on the pressing member 44. The connection between the first thread and the second thread is achieved by screwing them together, which improves the ease of connection and the stability of the connection of the pressing member 44.

[0051] Preferably, a first positioning surface 413 is formed in the second mounting groove 411, and a second positioning surface 423 is formed on the insertion section 421 and / or the limiting section 422 to position and cooperate with the first positioning surface 413, so as to prevent the rotating bushing 42 and the rotating disk 41 from rotating relative to each other, which would prevent the rotational friction resistance of the elastic pad 43 from acting on the rotating disk 41, resulting in a situation where it cannot be balanced with the weight of the LCD touch screen all-in-one machine.

[0052] Preferably, an annular groove (not shown) is provided on the insertion section 421 for the elastic gasket 43 to be inserted, thereby improving the ease of connection and stability of the elastic gasket 43.

[0053] The rotating disk 41 has a limiting groove 414 on the side facing the mounting bracket 2, and a limiting block 25 is provided on the side facing the rotating disk 41 on the mounting bracket 2. The limiting block 25 is embedded in the limiting groove 414 and cooperates with the limiting groove 414 to limit the rotation angle of the rotating disk 41.

[0054] Furthermore, a first blocking wall 415 and a second blocking wall 416 are respectively formed on the two side walls of the limiting groove 414. The first blocking wall 415 is in blocking cooperation with the first end 251 of the limiting block 25, and the second blocking wall 416 is in blocking cooperation with the second end 252 of the limiting block 25, so as to realize the precise positioning of the horizontal and vertical screen switching of the LCD touch screen all-in-one machine.

[0055] The rotating disk 41 has multiple connection holes 417 for connecting to the LCD touch screen all-in-one machine via screws, pins, or dowels.

[0056] The lifting mechanism includes a pneumatic spring 31, which is disposed on both sides of the mounting frame 2. A first mounting block 11 is provided on the bracket 1 below the mounting frame 2. A first connecting block 311 connected to the first mounting block 11 is provided at the bottom of the pneumatic spring 31, and a second connecting block 312 connected to the surface of the mounting frame 2 is provided at the top of the pneumatic spring 31. The supporting force of the pneumatic spring 31 on the mounting frame 2 is balanced with the downward force generated by the weight of the LCD touch screen all-in-one machine. This allows the LCD touch screen all-in-one machine to stop at any position within the stroke range of the pneumatic spring 31 without external lifting force. Lifting only requires applying an external lifting force to disrupt the force balance, improving the convenience of lifting and reducing the structural complexity of the lifting structure. Furthermore, the supporting force of the pneumatic spring 31 can be adjusted by regulating the air pressure inside the pneumatic spring 31, adapting to LCD touch screen all-in-one machines with arbitrary counterweights and expanding its applicability.

[0057] Specifically, a first connecting hole 313 is provided on the first connecting block 311, and a second connecting hole 111 is provided on the first mounting block 11 to cooperate with the first connecting hole 313. The first connecting block 311 and the first mounting block 11 are connected and fixed by means of screws, bolts or pins passing through the first connecting hole 313 and the second connecting hole 111.

[0058] Furthermore, a mounting protrusion 112 is provided on the top or bottom of the first mounting block 11, and a second connecting hole 111 is provided on the mounting protrusion 112. When the mounting protrusion 112 is located at the bottom of the first mounting block 11, a clearance groove 113 for the pneumatic spring 31 to pass through is also provided on the first mounting block 11.

[0059] Furthermore, a third connecting hole 314 is provided on the second connecting block 312, and a fourth connecting hole 24 that cooperates with the third connecting hole 314 is provided on the mounting bracket 2. The second connecting block 312 and the mounting bracket 2 are connected and fixed by means of screws, bolts or pins passing through the third connecting hole 314 and the fourth connecting hole 24.

[0060] The mounting frame 2 has two oppositely arranged receiving grooves 27 and insertion protrusions 26 at both ends of the receiving grooves 27. The mounting frame 2 has two oppositely arranged guide rods 5, the two ends of which are inserted into the insertion protrusions 26 and extend to the outside of the mounting frame 2 to connect with the bracket 1.

[0061] Specifically, a second mounting block 12 is provided on the bracket 1 at a position above the mounting bracket 2. A first insertion hole 114 is provided on the first mounting block 11, and a second insertion hole 121 is provided on the second mounting block 12. A first insertion post 51 is provided at the top of the guide rod 5 to be inserted into the second insertion hole 121, and a second insertion post 52 is provided at the bottom to be inserted into the first insertion hole 114.

[0062] Furthermore, the insertion protrusion 26 is provided with a third insertion hole 261 for the guide rod 5 to be inserted into. It also includes two opposing damping members 6 sleeved on the guide rod 5. The damping member 6 includes an insertion collar 61. A limiting flange 62 is formed at the end of the insertion collar 61. The insertion collar 61 is sleeved on the guide rod 5 and inserted into the third insertion hole 261 on one side of the receiving groove 27. At this time, the limiting flange 62 abuts against the top position of the insertion protrusion 26 (bottom groove wall of the receiving groove 27). The damping element 6 provides lifting resistance for the guide rod 5. In the static state, it provides downward resistance, supports the pneumatic spring 31, and balances the force of the LCD touch screen all-in-one machine with the weight of the machine, maintaining the height balance of the LCD touch screen all-in-one machine, reducing the counterweight required for the pneumatic spring 31, and improving the service life of the pneumatic spring 31. In the lifting state, it provides lifting resistance, so that the lifting of the LCD CNC all-in-one machine has a good lifting feel and avoids the lifting of the LCD CNC all-in-one machine under slight force.

[0063] Furthermore, a retaining member 7 is provided in the receiving groove 27, and receiving grooves 71 are formed at both ends of the retaining member 7. The two ends of the retaining member 7 abut against the top groove wall and the bottom groove wall of the receiving groove 27, respectively. At this time, the limiting protrusion 62 is accommodated in the receiving groove 71 to limit the position of the damping member 6 on the guide rod 5, so as to prevent the damping member 6 from disengaging from the guide rod 5 when the mounting frame 2 is lifted and lowered by the lifting mechanism.

[0064] Preferably, the abutment 7 is fixed in the receiving groove 27 by means of screws, bolts or pins.

[0065] Preferably, the mounting bracket 2 has an insertion groove 28 that connects to the receiving groove 27, the pneumatic spring 31 is at least partially embedded in the insertion groove 28, and the top end of the pneumatic spring 31 abuts against the top groove wall of the receiving groove 27, and the second connecting block 312 rests on the surface of the mounting bracket 2.

[0066] A limiting area 13 is provided on the bracket 1, the rotating mechanism is located in the limiting area 13, the mounting frame 2 is located on one side of the bracket 1 and connected to the rotating mechanism, and the lifting mechanism is located on the mounting frame 2 and connected to the bracket 1. The limiting area 13 is used to limit the lifting stroke of the mounting frame 2 on the bracket 1 and to limit the radial displacement of the rotating mechanism on the bracket 1 through the rotating mechanism, thereby improving the stability of lifting and rotation.

[0067] The display device adjustment base provided in this embodiment, on the one hand, by setting a lifting mechanism with a pneumatic spring 31 on the mounting bracket 2, can utilize the adjustable air pressure characteristic of the pneumatic spring 31 to adjust the air pressure in the pneumatic spring 31 according to the weight of the LCD touch screen all-in-one machine, so that the supporting force of the pneumatic spring 31 on the LCD touch screen all-in-one machine is balanced with the weight of the LCD touch screen all-in-one machine (the damping force of the damping element 6 can also be added to achieve three-force balance). So that the lifting and lowering of the LCD touch screen all-in-one machine requires the application of an external force to break the force balance to achieve lifting and lowering, and the lifting and lowering can be stopped after the external force is removed. This allows the LCD touch screen all-in-one machine to be raised, lowered and stopped at will within the stroke range of the pneumatic spring 31 without the need for a locking mechanism, improving the convenience of lifting and lowering; and it can be adapted to LCD touch screen all-in-one machines with any counterweight by adjusting the air pressure in the pneumatic spring 31.

[0068] On the other hand, by setting a rotating mechanism on the mounting bracket 2, a rotating bushing 42 is set inside the rotating disk 41 of the rotating mechanism. The end of the rotating bushing 42 extends into the groove 21 of the mounting bracket to form a first mounting groove 23 with the groove wall of the groove 21. By setting multiple elastic pads 43 in the first mounting groove 23 and sleeved on the rotating bushing 42, and pressing the elastic pads 43 with the pressing member 44, a frictional force is formed between the elastic pads 43 and the rotating bushing 42 to prevent the rotation of the rotating bushing 42. By adjusting the number of elastic pads 43... The magnitude of the friction force is adjusted to balance the weight of the LCD touch screen all-in-one machine. This means that switching between portrait and landscape modes requires applying a rotating external force to the LCD touch screen all-in-one machine to disrupt the force balance. After the external force is removed, the LCD touch screen all-in-one machine stops at any rotation angle within the rotation stroke of the rotating mechanism without the need for rotation locking, thus improving the convenience of rotation. Furthermore, it can adapt to LCD touch screen all-in-one machines with any counterweight based on the number of elastic pads 43 set, requiring only the same elastic pads 43 to be manufactured, reducing production costs.

[0069] The display device adjustment base provided in this embodiment has the advantages of convenient use, wide applicability and low manufacturing cost. It effectively realizes the purpose of simultaneously raising and lowering and rotating the LCD touch screen all-in-one machine at will, thereby improving the adjustment convenience of the LCD touch screen all-in-one machine.
