The following are all working processes and working principles of the above embodiments:
initial state: the magnetic plates 74 on the outer wall of the sliding column 72 face downwards under the action of gravity, the magnetic plates 74 are close to each other and are in a collision state, and the magnetism of the magnetic plates 74 and the magnetism of the magnetic blocks 710 are opposite to each other, so that the magnetic plates 74 on the outer wall of the sliding column 72 on the lowest part are adsorbed to the magnetic blocks 710, and the sliding columns 72 are blocked by the magnetic plates 74 when in initial use, so that the sliding columns 72 are always equidistant, and then the power line 4 is sequentially clamped into the split collet 73.
During operation, firstly, the display screen board 1 is moved to a position required to be used through the pulley frame 2, then the plug 6 is pulled to be matched with the power line 4 to be inserted into a power jack of a display field, after the plug 6 is inserted, the sucking disc 717 on one surface of the protective box 5 is adsorbed with a wall surface, so that the firmness of the plug 6 and the power socket are increased, the sliding column 72 can be adjusted according to the length of the actual power line 4 during insertion, the sliding plate 82 is pulled outwards along the long column 810, the sliding plate 82 is not positioned at the lower part of the sliding column 72 at the bottommost part of the sliding groove 71, then the sliding column 72 at the bottommost part is pulled downwards along the sliding groove 71, the extending length of the power line 4 can be increased, at the moment, the length of the power line 4 at the rear part of the display screen board 1 is reduced, then the moving sliding plate 82 is moved again to be attached to the display screen board 1 and the magnetic block 710, the subsequent triggering of the line anti-dragging component is facilitated, the quantity and the distance of the sliding column 72 can be adjusted according to the length required for the insertion of the actual power line 4, the sliding plate 82 is adjusted, the length required by the sliding column is pulled, the sliding plate 82 is not pulled downwards, the length of the sliding plate 72 is adjusted, the extra power line can be prevented from being stored in the ground, and the situation that the extra power line can be prevented from being scattered around the display screen board is prevented from being stored, and the display screen board is automatically is prevented from being scattered, and the power line is stored in the ground;
further, after the sliding post 72 is adjusted according to the actual situation, at this time, the height of the sleeve 76 needs to be readjusted according to the extending length, only the auxiliary clamping plate 713 needs to be held by hand to be pulled outwards, and then the sliding post 712 is driven to move in the sleeve 76 and pull the supporting spring 711 to stretch, at this time, the auxiliary clamping plate 713 cannot be embedded and clamped in the limiting clamping groove plate 714, then the auxiliary clamping plate 713 can be pulled downwards to drive the sleeve 76 to move downwards along the moving groove 75, the auxiliary clamping plate 713 can be loosened after moving to a proper position, at this time, the supporting spring 711 in the sleeve 76 is reset and reset, and then the sliding post 712 and the auxiliary clamping plate 713 are pulled to be reset, so that the auxiliary clamping plate 713 is clamped in the corresponding sliding post 72 by adjusting the arc clamping sleeve 78, and the auxiliary spring 77 outside the arc clamping sleeve 78 is guaranteed to be in a state of being normally not compressed after being clamped, so that the auxiliary spring 77 and the arc clamping sleeve 78 can keep the sufficient reset and the length of the limiting locking, and the rest power wire 4 is shortened, and the rest power wire 4 can not be matched with the original length after the auxiliary spring 77 is pulled for a short distance, and the reset condition is not suitable for the power wire 4, and the device is optimized at the same time;
further, when the power cord 4 falls on the ground and is caught by the feet of the passer-by and pulled, the sliding column 72 attached to the magnetic block 710 will first slide down along the sliding groove 71 along the pulled power cord 4, then drive the sliding column 72 on the upper portion to move continuously downward, when the limiting plate 79 on the lower portion of the arc-shaped jacket 78 moves close to the magnetic block 710, the limiting plate 79 will be blocked on the upper portion of the magnetic block 710 due to the fixed connection relationship of the magnetic block 710, so that the sliding column 72 corresponding to the arc-shaped jacket 78 and the power cord 4 cannot slide continuously downward smoothly, and after the power cord 4 on the plug 6 is pulled, the curved power cord 4 in the protection box 5 will be pulled, so that the collar 715 on the outer wall of the power cord 4 is pulled to the inner wall of the protection box 5, and the hole 716 of the inner wall of the protection box 5 is pulled to be smaller than the size of the collar, therefore, the collar 715 is blocked by the protection box 5 and cannot continuously pull the power cord 4 at one side of the plug 6, through the power cord 4 with the allowance, the power cord 4 can be automatically lengthened when the power cord 4 is accidentally pulled, the situation that the pedestrian is stumbled or falls down due to the continuous blocking of the power cord is avoided, the power cord 4 with the allowance can also enable the pedestrian to feel that feet are stumbled, after the power cord 4 is not pulled, the auxiliary spring 77 and the homing spring 716 can both help the power cord 4 to reset to the normal state, and the situation that the plug 6 and the power supply fall off after the power cord 4 is limited and the phenomenon that the image display screen panel 1 is stopped due to the pulling is also avoided, so that the occurrence of the situation is reduced, the display panel 1 is favorable for stably developing graphic display work;
further, since the sliding plate 82 is attached to the lower portion of the bottommost sliding post 72, when the sliding post 72 slides downward, the sliding plate 82 is pressed to move downward, and since one end of the spring 84 is fixedly connected with the sliding plate 82, the spring 84 is pulled to shrink, so that the other end of the spring 84 drives the supporting shaft 83 to rotate, and further drives the cleaning plate 85 and the dustproof cloth 86 to wipe and clean the screen of the display screen 1, so that the display screen 1 is kept clean, the condition that the screen of the display screen 1 is blurred due to dust accumulation is avoided, and a good visual display effect of the display screen 1 is ensured all the time;
the supporting shaft 83 rotates and drives the protruding wheel disc 87 synchronously, so that the protruding part of the protruding wheel disc 87 rotates downwards, the switch button 89 outside the alarm lamp 88 can be abutted to the protruding wheel disc, the alarm lamp 88 can be opened by the switch button 89, a passer-by or a user can be effectively reminded of the condition that the power line 4 is pulled or stumbled to a human body, the function of warning the passer-by is played, and the probability of trampling damage and power failure caused by scattering of the power line 4 on the ground is further reduced.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
