Description

Technical Field

[0001] The invention relates to the technical field of LED display screens, and in particular to a connection structure and an LED display screen which is convenient for front and rear maintenance. Background Art

[0002] LED display screen is an electronic display screen composed of LED dot matrix. It changes the screen display content form such as text, animation, picture, video in time by turning on and off the red and green light beads, and controls the component display through modular structure. In terms of structure, LED display screen is composed of modules. Generally, the smallest unit is a module, and then several modules are installed on the unit box, and finally assembled into an LED display screen of required size. Hereinafter referred to as display screen.

[0003] There are generally two types of functional mechanisms currently available for front and rear maintenance of modules: 1. A magnet is set on the back of the module, an iron sheet is set at the corresponding position of the box, and then the module is mounted on the box by magnetic force. When front maintenance is required, the module is sucked by a special tool and pulled forward for maintenance; when rear maintenance is required, a thrust is applied to the back of the box to push the module forward, and then the module is taken out backward through the maintenance hole set in the box to achieve rear maintenance. 2. The module and the box are locked and connected by a specific rotary locking mechanism; rear maintenance is achieved by operating the tightness of the rotary locking mechanism on the back of the box. When performing front maintenance, a maintenance hole located in the middle of the four display points needs to be set on the module; a special wrench is used to operate the tightness of the rotary locking mechanism through this maintenance hole that completely passes through the entire module to achieve front maintenance;

[0004] For the first method, since the magnetism will decay over time, the module is easy to fall off. Therefore, a safety rope needs to be set between the module and the box to prevent the module from falling off the box due to the decay of magnetism and causing safety accidents. For the second method, for small-pitch display screens, due to the small pitch, the maintenance hole is very small (generally the diameter of the maintenance hole is less than 1.6mm). It is difficult to find the maintenance hole during front maintenance, and the operation is very difficult. For display screens with even smaller pitches, the position between the four display points is very small, so it is impossible to set the maintenance hole. Summary of the invention

[0093] In a specific embodiment of the present application, the step of connecting the first connecting component with the second connecting component includes: when the lock plate 1 slides toward the direction of the lock plate spring 2 due to external pressure, the trigger spring pushes the trigger column on the trigger switch into the trigger hole 104, the lock plate 1 is locked, and the locking groove 101 is interlaced with the bolt seat guide groove 32; the bottom of the bolt seat 12 is pushed toward the direction of the bolt seat guide groove 32, and the lock head 13 slides and moves the bolt seat guide groove 32. When the bottom of the bolt seat 12 completely enters the bolt seat guide groove 32, under the action of the lock head spring, the lock head 13 is locked in the bolt seat guide groove 32;

[0094] The steps of removing the module 16 from the front of the box 17 include: using a magnet tool 18 to magnetically attract the side of the module 16 away from the first connecting component, under the action of the magnetic force, the trigger spring 4 is compressed, the trigger column withdraws from the trigger hole 104, and under the pushing force of the lock plate spring 2, the lock plate 1 moves in a direction away from the lock plate spring 2, the locking groove 101 coincides with the bolt seat guide groove 32, and the bottom of the bolt seat 12 moves out of the bolt seat guide groove 32;

[0095] The steps of removing the module 16 from the rear of the box body 17 include: pressing the push rod 9 in the direction of the first connecting part, passing through the push rod guide groove 102 of the lock plate 1, and the trigger column withdraws from the trigger hole 104. Under the pushing force of the lock plate spring 2, the lock plate 1 moves in the direction away from the lock plate spring 2, the locking groove 101 coincides with the pin seat guide groove 32, and the bottom of the pin seat 12 moves out of the pin seat guide groove 32.

[0096] In a specific embodiment of the present application, as described in the following steps:

[0097] 1) Install the first connecting component on the module 16 and the second connecting component on the box 17.

[0098] 2) The initial state of the first connecting component is that the lock plate 1 is tightly pressed against the lock plate stop 31 of the locking seat 3 under the action of the lock plate spring 2; first, the lock plate 1 must be manually pulled inward so that the lock plate 1 overcomes the elastic force of the lock plate spring 2 and moves into the locking seat 3 until the trigger hole 102 of the lock plate 1 of the trigger switch 5 is triggered, thereby completing the locking state of the lock plate 1.

[0099] 3) Move the module 16 with the first connecting component installed to the front of the box 17. This action is applicable to the front and back maintenance of the box 17. For front maintenance, push the front of the module 16 to the front of the box 17; for rear maintenance, hold the back of the module 16 and pull it to the front of the box 17. Fig.13 shown.

[0100] When the first connecting member moves to the locking plate 1 and presses the locking head 13 of the second connecting member, the first connecting member continues to move, and the locking head 13 is forced to move inward and shrink under the action of the locking plate 1. Fig.14 shown.

[0101] When the first connecting member is moved by hand until the lock head 13 crosses the lock plate 1, the lock head 13 pops out under the elastic force of the lock plate spring 2, so that the first connecting member and the second connecting member complete the locking function. The module 16 is locked on the box body 17 without falling off. Fig.15 shown.

[0102] 4) Front maintenance function (ie, removing the module 16 from the front of the display):

[0103] When performing the front maintenance function, a magnet tool 18 is used to fit close to the front of the module 16. The magnet tool 18 and the trigger magnet 6 set on the trigger switch 5 have different magnetic properties. Under the action of magnetism, the trigger switch 5 will move toward the module 16, so that the trigger switch 5 will fall off from the trigger hole 104 of the lock plate 1; at this time, the lock plate 1 moves outward under the elastic force of the lock plate spring 2, so that the lock plate 1 leaves the lock head 13, so that the first connecting component loosens the second connecting component, and the module 16 can be removed from the front of the box body 17. Fig.16 and Fig.17 shown.

[0104] 5) Post-maintenance function (ie, removing the module 16 from the back of the display):

[0105] During the post-maintenance, manually press the push rod 9 on the back of the box 17, so that the push rod 9 moves forward, passes through the push rod guide groove 102 of the lock plate 1, and presses the trigger switch 5. The trigger switch 5 moves forward with the push rod 9, thereby falling off the trigger hole 104 of the lock plate 1; at this time, the lock plate 1 moves outward under the elastic force of the lock plate spring 2, so that the lock plate 1 leaves the lock head 13, so that the first connecting part releases the second connecting part, and the module 16 can be removed from the box 17. After the first connecting part releases the second connecting part, let go and stop pressing. The push rod 9 will rebound to its initial state under the action of the push rod spring 10. Fig.18 and Fig.19 shown.
