Description

The present invention takes up the field of advertising equipment, and particularly relates to an display device for LED signboards.

With the development of society, LED signboards are used by many people due to their versatility and sharpness, but compared to traditional signboards, LED signboards are expensive and precise, and the usage environment is limited. , Like a general signboard, it is fragile when placed in the open air. Here, the importance of the exhibition equipment becomes clear. However, the LED signboard has a large weight and volume, and is further energized. Most of the existing LED signboard display devices have defects such as replacement inconvenience and replacement risk, and many display devices are fixed, heavy and have poor cost performance. There are also movable exhibition devices, but they are not preferable from the viewpoint of safety because they lack fixing means.

Positioned at 28, the first compression spring 69 is compressed by the weight of the sign fixing body 62, the tow rope 70 is loosened, the second starting block 75 is pushed by the second compression spring 72 to enter the self-locking space 23, and The magnetism of the second starting block 75 repels the self-locking magnet 67, and the self-locking magnet 67 expands the first self-locking rod 66 and the second self-locking rod 102 to both sides by the repulsive force, thereby causing a tension spring. 65 is stretched, the self-locking head 103 enters the lock space 104, where the sign fixing main body 62 and the fixing base 73 are locked, and the interfering plate 63 interlocks the connecting rod 61 with the interfering plate compression spring 64. The upper end of 61 is allowed to enter the fixed space 20.

The operating procedure of the present invention is as follows.

1. Open the lid plate 58, attach the signboard to be displayed in the mounting space 26 of the signboard fixing main body 62, close the lid plate 58, push the present invention to the exhibition position, and start the first motor 59 to activate the drive shaft 60. By rotating, the rotating pulley 47 rotates in conjunction, the rotating belt 46 is rotated, and the connecting rod 44 interlocks to rotate the moving table 43 along the rail 15 in the storage space 14. Further, the rotation of the rotating pulley 47 causes the first pulley 86 and the spline cylinder 45 to rotate in conjunction with each other, and by rotating the second pulley 84, the first driven shaft 85 and the first umbrella gear 83 are rotated. The second umbrella gear 81 and the second driven shaft 82 rotate in conjunction with each other, and by rotating the centrifugal wheel 101, the centrifugal block 78 is moved outward by centrifugal force, and the lid plate self-locking rod 77 is pushed. The lid plate lock 106 is allowed to enter the lid plate lock space 107 to limit the position, where the lid plate 58 can be self-locked and the lid plate 58 cannot be opened from the outside.

2. The decoupling magnet 89 operates at the same time as the operation of the first motor 59, and the spline cylinder 45 rotates to rotate the third driven shaft 88 to rotate the first friction plate 98, and the decoupling magnet 89 and the decoupling magnet 89. Due to the exclusion force with 90, the compression plate 91 resists the traction force of the compression plate tension spring 99 and lowers, and the first friction plate 98 and the third driven shaft 88 resist the traction force of the release tension spring 94 and lower. In addition, by contacting with the second friction plate 92, the second friction plate 92 and the fourth driven shaft 95 rotate in conjunction with each other, and the third pulley 97 and the fourth pulley 93 rotate, and the third pulley 97 Further transmitted by the second belt 96 to rotate the fifth pulley 108, the fourth pulley 93 is further transmitted by the third belt 100 to rotate the sixth pulley 87, and with the fifth pulley 108 and the sixth pulley 87. By rotating the left and right sixth driven shafts 49, the moving elevating block 50 is lowered by its own weight, and the elevating plate 51, the elevating rod 52, and the friction block 53 are lowered in conjunction with each other, and the friction block 53 is further lowered. When it comes into contact with 57, the ring 57 is locked, and the friction block 53 moves downward and comes into contact with the bottom surface of the self-locking space 17, the sensor 54 transmits, the decoupling magnet 89 is stopped, and compression is performed by the traction force of the compression plate tension spring 99. The board 91 rises, the disengagement tension spring 94 raises the third driven shaft 88, raises the first friction disc 98, and the first friction disc 98 disengages from the second friction disc 92, the second friction disc. 92 stops the rotation.

3. After deciding the sign for the exhibition, stop the first motor 59, operate the second motor 34 to rotate the elevating shaft 36, lower the elevating slider 38, and the elevating slider 38 interlocks the fixed block 38. After allowing the spring to enter the fixed space 20, the fixing magnet 42 magnetically attracts the telescopic block 39, and the telescopic block 39 is moved outward by the attractive force to fix the sign fixing main body 62 and also to fix the fixed block. When 38 enters the fixed space 20, the connecting rod 61 is pushed downward, the interfering plate compression spring 64 is compressed, and the interfering plate 63 is lowered by interlocking the connecting rod 61, so that the second starting block 75 is second. The thrust of the compression spring 72 is resisted and returned to the second starting space 72, the second compression spring 72 is compressed, and the traction force of the tension spring 65 causes the first self-locking rod 66 and the second self-locking rod 102 to move inward. After exercising, the sign fixing body 62 and the fixing base 73 are unlocked, the second motor 34 rotates in the reverse direction to rotate the telescopic shaft 36 in the reverse direction, and the pulling force of the pull-back spring 35 raises the elevating slider 37 to fix the block. 38 is raised, and the sign fixing body 62 is raised in conjunction with it to enter the exhibition space 13, and since the first compression spring 69 is more elastic than the second compression spring 72, the first starting block 68 is the first compression spring. When it is pushed up by 69 and the mounting space 26 and the exhibition area 71 overlap, the signboard can be displayed and the second motor 34 is stopped.

4. When the exhibition is completed, the second motor 34 is started to rotate the elevating shaft 36 to lower the elevating slider 38, and the fixing block 38 and the sign fixing main body 62 are interlocked to lower and fix the sign. When the bottom surface of the main body 62 and the fixing base 73 come into contact with each other, the suction electromagnet 40 is activated, the suction electromagnet 40 magnetically attracts the expansion / contraction block 39, and the expansion / contraction block 39 moves inward to the expansion / contraction space 12 by the attraction force. Returning, the second motor 34 rotates in the reverse direction to rotate the telescopic shaft 36 in the reverse direction, the pulling force of the pulling back spring 35 raises the elevating slider 37, raises the fixed block 38, and the thrust of the interfering plate compression spring 64 interferes. The plate 63 rises to raise the connecting rod 61, the thrust of the second compression spring 72 raises the second starting block 75, and the repulsive force between the second starting block 75 and the self-locking magnet 67 causes the self-locking magnet. 67 spreads the first self-locking rod 66 and the second self-locking rod 102 to both sides and stretches the tension spring 65, the self-locking head 103 enters the lock space 104, and the sign fixing main body 62 and the fixing base 73 are reattached. When the fixed block 38 is locked and the fixed block 38 returns to the initial position, the second motor 34 is stopped and the suction electromagnet 40 is stopped.

According to the above method, the employee in the field can make various modifications according to the working situation within the scope of the present invention.
