Description

Technical Field

[0001] The invention relates to the technical field of terminal maintenance, in particular to a terminal maintenance device for communication visual services. Background Art

[0002] Terminal is an input and output device connected to a computer system, usually far away from the computer. It can be divided into several categories according to its functions. Terminals with certain processing functions are called smart terminals or intelligent terminals, which have their own microprocessors and control circuits; terminals without these functions are called dumb terminals, which have no microprocessors. Terminals that support conversations or processing with computers are called interactive terminals or online terminals.

[0003] The existing communication visual service terminals often encounter various equipment problems during use. When these terminal devices fail, they need to be repaired. Since some communication visual service terminals are installed at a high position, maintenance personnel are required to climb up. The existing terminal maintenance device lacks the function of providing a ladder for maintenance personnel. At the same time, when performing terminal maintenance, it is often necessary to repair the PCB board of the terminal equipment. The PCB board is the core component of the terminal equipment and needs to be placed and fixed during maintenance. The existing terminal maintenance device lacks the function of fixing the PCB board. For this reason, we propose a terminal maintenance device for communication visual services. Summary of the invention

A lower clamping block 2 650 is fixedly installed on the upper end of the outer wall of the middle block 1 630 symmetrically in the front and rear.The upper clamp block 2 660 is fixedly installed on the upper end of the outer wall of the two lower clamp blocks 650, a motor base 700 is fixedly installed on the left rear end of the upper end of the outer wall of the bottom plate 500, a motor 710 is fixedly installed on the upper end of the outer wall of the motor base 700, a connecting shaft 2 720 is fixedly installed on the output end of the motor 710, and a pulley 1 730 is fixedly installed on the outer wall of the connecting shaft 2 720, a support frame 740 is fixedly installed on the right rear end of the upper end of the outer wall of the bottom plate 500, a connecting shaft 3 750 is fixedly installed on the output end of the support frame 740, and a pulley 2 760 is fixedly installed on the outer wall of the connecting shaft 3 750, and the pulley 2 760 and the pulley 1 730 are connected through a belt 770, and the lower end of the belt 770 passes through the lower clamp block 1 610 and the upper The first clamp block 620 is provided between the first clamp block 620, and the lower end of the belt 770 is fixedly connected to the lower clamp block 610 and the upper clamp block 620, the upper end of the belt 770 passes through the lower clamp block 2 650 and the upper clamp block 2 660, and the upper end of the belt 770 is fixedly connected to the lower clamp block 2 650 and the upper clamp block 2 660, the belt 770 passes through the opening 1 640, and the upper ends of the outer walls of the two sliding plates 600 are symmetrically fixed with connecting frames 800. When the motor 710 is started, it can drive the pulley 1 730 to rotate, thereby driving the belt 770 and the pulley 2 760 to rotate. When the belt 770 rotates, its lower side will drive the sliding plate 600 on the left to slide through the two lower clamp blocks 1 610 and the upper clamp block 1 620, and the belt 770 rotates. When the belt 770 rotates, the upper side will drive the sliding plate 600 on the right side to slide through the two lower clamping blocks 650 and the upper clamping block 660. Since the upper and lower sides of the belt 770 rotate in opposite directions when rotating, the sliding plates 600 on both sides can move closer to or away from each other when sliding. Two openings 801 are provided on the upper end of the outer wall of the sliding box 400. The upper end of the outer wall of the connecting frame 800 passes through the opening 801. A connecting plate 810 is fixedly installed on the upper end of the outer wall of each pair of connecting frames 800 on the left and right sides. The upper ends of the outer walls of the connecting plates 810 on both sides are linearly arranged with threaded holes 840.

An extruded rubber block 850 is fixedly installed on the upper end of the outer wall of the fixed block 820. When the sliding plates 600 on both sides can move closer to or farther from each other when sliding, the connecting plates 810 on both sides can move closer to or farther from each other, so that the PCB board to be repaired can be clamped by the extruded rubber blocks 850 on both sides that are close to each other. At the same time, the distance between the two fixed blocks 820 and the extruded rubber block 850 on each side can be adjusted through the threaded hole 1 840 and the threaded hole 2 830 to adapt to the clamping of PCB boards of different lengths. A clamping button 860 and a release button 870 are fixedly installed on the front side of the upper end of the outer wall of the sliding box 400.

[0036] Furthermore, the distance between the two lower clamping blocks 1 610 , the distance between the two lower clamping blocks 2 650 and the width of the belt 770 are the same, so that the distance between the two lower clamping blocks 1 610 and the two lower clamping blocks 2 650 can clamp the belt 770 .

[0037] Furthermore, the width of the opening 1 640 is greater than the width of the belt 770 , so that the belt 770 can slide freely in the opening 1 640 .

[0038] Furthermore, a fixed frame 420 is fixedly installed on the right side of the inner wall of the sliding box 400, and the left and right sides of the inner wall of the fixed frame 420 are rotatably connected with screws 900. The outer wall of the screw 900 is threadedly connected with two sliding blocks 910. The upper ends of the outer walls of the two sliding blocks 910 are both rotatably connected with intermediate rods 920. The upper ends of the outer walls of the two intermediate rods 920 are simultaneously rotatably connected with intermediate blocks 930. The upper ends of the outer walls of the intermediate blocks 930 are fixedly installed with a sliding box 940. A drawer 950 is slidably connected inside the sliding box 940. A handle 960 is fixedly installed at the front end of the outer wall of the drawer 950. The right side of the outer wall of the sliding box 400 A groove 970 is provided, and the right end of the outer wall of the screw rod 900 passes through the inner wall of the groove 970 and is fixedly installed with a turntable 980. A crank 990 is fixedly installed on the right side of the outer wall of the turntable 980. The maintenance personnel can drive the turntable 980 and the screw rod 900 to rotate by turning the crank 990, thereby driving the two sliding blocks 910 to move closer to or away from each other, and then make the middle block 930 slide up and down through the two middle rods 920, thereby driving the sliding box 400 to slide up and down, so that the sliding box 400 can be folded and hidden when not in use, and items can be stored through the drawer 950.

[0039] Furthermore, the threads on the left and right sides of the screw rod 900 are in opposite directions, so that when the screw rod 900 rotates, it can drive the two sliding blocks 910 to move closer to each other or away from each other.

[0040] Furthermore, the crank handle 990 and the turntable 980 are both located inside the groove 970, so as to facilitate the storage of the sliding box 400.

[0041] Furthermore, slide bars 401 are symmetrically fixedly installed on the left and right sides of the outer wall of the sliding box 400, and a groove three 402 is opened on the inner wall of the shell 100. The slide bar 401 is slidably connected to the groove three 402, so that the sliding connection between the sliding box 400 and the shell 100 is smoother.

[0042] In summary, the workflow of the present invention is as follows: during specific use, the maintenance personnel can raise or retract the ladder by rotating the left bracket 270 and the right bracket 220, and can store the ladder through the storage frame 200. When it is necessary to perform a withstand voltage test on the equipment, the maintenance personnel can clamp the two test chucks 350 on the equipment to be tested, thereby testing the withstand voltage capability of the device. At the same time, the winding wheel 320 can be rotated by rotating the crank 330 to store the connecting cable 340, thereby preventing the equipment from being damaged. The PCB board of the terminal device needs to be repaired by pressing the clamping button 860. At this time, the motor 710 can drive the pulley 1 730 to rotate when it is started, thereby driving the belt 770 and the pulley 2 760 to rotate. When the belt 770 rotates, its lower side will drive the sliding plate 600 on the left to slide through the two lower clamping blocks 1 610 and the upper clamping block 1 620. When the belt 770 rotates, its upper side will drive the sliding plate 600 on the right to slide through the two lower clamping blocks 2 650 and the upper clamping blocks 2 660. Since the belt 770 rotates in opposite directions on the upper and lower sides, the sliding plates 600 on both sides can approach each other when sliding. When the sliding plates 600 on both sides can approach each other when sliding, the connecting plates 810 on both sides can be driven to approach each other, so that the PCB to be repaired can be clamped by the extruded rubber blocks 850 on both sides approaching each other. At the same time, the distance between the two fixed blocks 820 and the extruded rubber blocks 850 on each side can be adjusted through the threaded holes 840 and the threaded holes 830 to adapt to PCBs of different lengths. The clamping of the CB board can be released by pressing the release button 870 at the end of maintenance. Finally, the maintenance personnel can rotate the turntable 980 and the screw 900 by turning the crank handle 990, thereby driving the two sliding blocks 910 to move closer to or away from each other, and then make the middle block 930 slide up and down through the two middle rods 920, thereby driving the sliding box 400 to slide up and down, so that the sliding box 400 can be folded and hidden when not in use, and items can be stored through the drawer 950.
