DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1:

[0035] See also Figure 1-8An indoor small-pitch high-definition full-color display screen that is easy to lift, position, and install includes a display 1.

The driven wheel 2003 is rotatably connected to the support rods 2002. In the inner cavity, the motor box 2004 is fixedly connected to one side of the support rod 2002, the stepper motor 2005 is fixedly connected to the inner cavity of the motor box 2004, the transmission wheel 2006 is fixedly connected to the rotating shaft of the stepper motor 2005, the transmission wheel 2006 is rotatably connected to the inner cavity of the support rod 2002, the chain 2007 is clamped between the driven wheel 2003 and the transmission wheel 2006, the splint 2008 is clamped on one side of the chain 2007, the fixing screw 2009 is threadedly connected to the inner cavity of the splint 2008, the fixing screw 2009 passes through the chain 2007 and extends to the outside, the fixing plate 2010 is fixedly connected to one side of the splint 2008, and two clamping columns 2011 are provided. The two clamping columns 2011 are symmetrically slidably connected to the inner cavity of the fixing plate 2010, and the spring 2012 is fixedly connected to the two clamping columns 2011. 2002, the two fixing plates 3004 are fixed to the upper and lower ends of the inner side of the chain 2007, and the two fixing plates 3004 are fixed to the lower ends of the inner side of the chain 2007. The support shaft 3005 is symmetrically fixedly connected to the outer end of the connecting plate 3002, and the support shaft 3005 is fixedly connected between the two positioning plates 3004. The positioning assembly 3 also includes a positioning column 3006, a support rod 3007, a slide plate 3008, a slide groove 3009, a connecting plate 3010, a lower snap ring 3011, and an upper snap ring 3012. There are two positioning columns 3006, and the two positioning columns 3006 are symmetrically fixedly connected to the outer ends of the support shaft 3005. The slide plate 3008 is slidably connected to the outer ends of the support rod 3007. The support rod 3007 is provided with two.The back of the support rod 3007 is provided with a slide groove 3009, the slide plate 3008 is slidably connected to the slide groove 3009, the connecting plate 3010 is fixedly connected to the outer end of the slide plate 3008, the lower snap ring 3011 is fixedly connected to the bottom end of the connecting plate 3010, and the upper snap ring 3012 is rotatably connected to the inner cavity of the connecting plate 3010. The cross sections of the lower snap ring 3011 and the upper snap ring 3012 are both semicircular. There are screws and nuts threadedly connected to the upper clamping ring 3012. First, place the two support rods 2002 and the two support rods 3007 at the outer end of the wall at equal distances, and make the top parts of the support rods 2002 and the support rods 3007 on the same horizontal line, then clamp the four claws of the connecting plate 3002 into the outer end of the fixing ring 3001 on the back of the display 1, and use the set screws 3003 to fix the connecting plate 3002 to the back of the display 1, then clamp the positioning column 3006 at the outer end of the support shaft 3005 between the two positioning plates 3004 into the lower clamping ring 3011 at the bottom end of the connecting plate 3010, and rotate the upper clamping ring 3012 so that the lower clamping ring 3011 and the upper clamping ring 3012 are aligned. After being clipped together and fixed with screws and nuts, the display 1 can be flipped over after the bottom side of the back is fixed. At the same time, the stepper motor 2005 in the motor box 2004 drives the transmission wheel 2006 to rotate, and the chain 2007 between the transmission wheel 2006 and the driven wheel 2003 rotates clockwise. At this time, the lever 2013 on the right side of the chain 2007 is engaged with the transmission wheel 2006 to prevent the chain 2007 from continuing to rotate. At the same time, the height of the splint 2008 is fixed, and the display 1 is flipped over so that the card plate 2001 on the back of the display 1 conflicts with the card column 2011. At this time, the two card columns 2011 are facing each other in the inner cavity of the fixed plate 2010. The spring 2012 compresses when the two clamping posts 2011 enter the clamping plate 2001, and the spring 2012 relaxes, thereby connecting the fixing plate 2010 and the clamping plate 2001. This makes installation simple and convenient, and allows for precise positioning during installation. The triangular structure between the two clamping plates 2001 and the connecting plate 3002 also enhances the stability of the connection between the display 1 and the wall bracket. Conventional displays 1 are directly fixed to the outer end of the wall, making their height inadvisable. To adjust the height of the display 1, the stepper motor 2005 drives the transmission wheel 2006 to rotate counterclockwise, thereby raising the display 1 with the chain 2007.

[0036] Example 2:

[0037] See also Figure 9-12Based on the first embodiment, this embodiment provides a technical solution for an indoor small-pitch high-definition full-color display screen that is easy to lift, position, and install: a signal receiver 4 is fixedly connected to the outer end of the display 1, and a control board 5 is fixedly connected to the back of the display 1. The signal receiver 4 and the control board 5 are electrically connected, and the control board 5 and the stepper motor 2005 are electrically connected. A control module is provided in the inner cavity of the control board 5, and the control module contains an analog system. The analog system includes a device-side APP system. In order to facilitate the adjustment of the height of the display 1, the display 1 has a separate APP, which can be installed inside the terminal. The analog system inside the APP can send instructions to the control board 5, and the signal receiver 4 can conveniently receive signals from the APP, thereby facilitating the control of the stepper motor 2005.

[0038] The back of the display 1 is symmetrically fixedly connected with a cavity plate 6, the inner cavity of the cavity plate 6 is fixedly connected with a cooling pipe 7, one end of the cooling pipe 7 is fixedly connected with a return pipe 8, the other end of the return pipe 8 is fixedly connected with a cooler 9, the cooler 9 is fixedly connected to the back of the display 1, one side of the cooler 9 is fixedly connected with a drain pipe 10, the other end of the drain pipe 10 is fixedly connected with a pump 11, the pump 11 is fixedly connected to the inner cavity of the cavity plate 6, and the pump 11 is fixedly connected to the other end of the cooling pipe 7. The heat generated by the display 1 when in use is large. Traditionally, a fan is used to dissipate heat for the display 1. The fan has low heat dissipation efficiency and is noisy. The back of the display 1 is cooled by the coolant that can flow in the cooling pipe 7. The cooling process is carried out, and the cooling liquid after absorbing heat enters the cooler 9 through the return pipe 8 for cooling. The pump 11 then draws the cooled cooling liquid into the cooling pipe 7 through the discharge pipe 10. During the whole process, the cooling liquid has high cooling efficiency and fast speed. The upper and lower ends of the support rod 2002 and the support rod 3007 are symmetrically provided with clamping grooves 12. The inner cavity of the clamping groove 12 is rotatably connected with a rotating plate 13. The inner cavity of the clamping groove 12 is threadedly connected with a bolt 14. The bolt 14 is easy to rust when in contact with the air. It is extremely inconvenient to dismantle the support rod 2002 and the support rod 3007 at the outer end of the wall. The rotating plate 13 can seal the bolt 14 inside the clamping groove 12, reduce the contact area of the bolt 14 with the air, and thus slow down the oxidation rate of the bolt 14.

[0039] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0040] When working, first place the two support rods 2002 and the two support rods 3007 at the outer ends of the wall at equal distances, and make the top parts of the support rods 2002 and the support rods 3007 on the same horizontal line, then clamp the four claws of the connecting plate 3002 into the outer ends of the fixing ring 3001 on the back of the display 1, and use the set screws 3003 to fix the connecting plate 3002 to the back of the display 1, and then clamp the positioning column 3006 at the outer end of the support shaft 3005 between the two positioning plates 3004 into the lower clamping ring 3011 at the bottom end of the connecting plate 3010, and rotate the upper clamping ring 3012 so that the lower clamping ring 3011 and the upper clamping ring 3012 are clamped together, and fixed with screws and nuts. After fixing the bottom side of the back of the display 1, the display 1 can be flipped over, and at the same time, the stepping motor 2005 in the motor box 2004 drives the transmission wheel 2006 to rotate, and the transmission wheel 2006 The chain 2007 between the driven wheel 2003 rotates clockwise, and the lever 2013 on the right side of the chain 2007 engages with the transmission wheel 2006 to prevent the chain 2007 from continuing to rotate. At the same time, the height of the clamping plate 2008 is fixed, and the display 1 is turned over, so that the card plate 2001 on the back of the display 1 conflicts with the card column 2011. At this time, the two card columns 2011 slide toward each other in the inner cavity of the fixed plate 2010, and the spring 2012 is compressed. When the two card columns 2011 enter the card plate 2001, the spring 2012 relaxes, so that the fixed plate 2010 and the card plate 2001 are connected to each other, and the display 1 is turned over. The installation operation is simple and convenient, and the installation position can be positioned during installation. At the same time, the triangular structure between the two card plates 2001 and the connecting plate 3002 makes the connection between the display 1 and the wall bracket more stable. The traditional display 1 is directly fixed on the outer end of the wall and its height cannot be adjusted. When the height of the display 1 needs to be adjusted, the stepper motor 2005 drives the transmission wheel 2006 to rotate counterclockwise, so that the chain 2007 drives the display 1 to rise. In order to facilitate the adjustment of the height of the display 1, the display 1 has a separate APP, which can be installed inside the terminal. The internal analog system can send instructions to the control board 5, and the signal receiver 4 is convenient for receiving the signal of the APP, so as to facilitate the control of the stepper motor 2005. The heat generated by the display 1 when in use is large. Traditionally, a fan is used to dissipate heat for the display 1. The heat dissipation efficiency of the fan is low and the noise is large. The back of the display 1 is cooled by the flowing coolant in the cooling pipe 7. The coolant after absorbing heat enters the cooler 9 through the return pipe 8 for cooling. The pump 11 then draws the cooled coolant into the cooling pipe 7 through the discharge pipe 10. During the whole process, the coolant has high cooling efficiency and fast speed. The upper and lower ends of the support rod 2002 and the support rod 3007 are symmetrically provided with clamping grooves 12. The inner cavity of the clamping groove 12 is rotatably connected to the rotating plate 13. The inner cavity of the clamping groove 12 is threadedly connected to the bolt 14. The bolt 14 is easy to rust when in contact with the air.It is extremely inconvenient to disassemble the support rod 2002 and the support rod 3007 at the outer end of the wall. The rotating plate 13 can seal the bolt 14 inside the clamping groove 12, reducing the contact area between the bolt 14 and the air, thereby slowing down the oxidation rate of the bolt 14.
