LED display screen front maintenance tool
Technical Field
The invention relates to the technical field of LED display screens, in particular to a front maintenance tool for an LED display screen.
Background
With the development of technology, the application of the small-pitch display screen is more and more, and the application occasions of front maintenance are more and more limited by the installation space of the small-pitch display screen. In order to achieve front maintenance of the LED display, the display module must be removed from the front of the cabinet.
In the traditional module-taking magnetic attraction tool, the magnet module is parallel to the display screen module, the magnet module and the display screen module are close to each other, no power is needed, and the strength is difficult to control when the magnet module is close to the display screen module. Because the suction force is large when the LED lamp approaches to the module, the LED lamp is easy to collide with the lamp because the LED lamp is instantaneously flushed to the module; after the display screen module is taken out, the tool and the module are required to be separated, and a large force is required to operate in the process, so that the module is damaged destructively again, the display screen module is damaged, and the maintenance cost is increased; in addition, the existing operation tool needs professional technicians to operate, which is time-consuming and labor-consuming and increases personnel cost.
The defects are worth solving.

Detailed Description
The invention is further described below with reference to the drawings and embodiments:
as shown in fig. 1-3, a LED display front maintenance tool includes a handle 11 and a base 12. The invention realizes the up-and-down linkage of the whole device through the first button 21 and the second button 22. Specific:
the handle 11 is provided with a transverse beam 30, the transverse beam 30 is connected with the first button 21 and the second button 22 through a first screw 91 and a second screw 92 respectively, and the handle 11 is provided with a button groove (not shown in the figure) for accommodating the first button 21 and the second button 22. The first button 21 and the second button 22 are disposed on opposite sides of the cross beam 30, and in this embodiment, the first button 21 is disposed below the cross beam 30 and the second button 22 is disposed above the cross beam 30.
The both ends of crossbeam 30 pass through third screw 93 and connecting rod 40's upper end fixed connection, and connecting rod 40 overcoat has spring 70, and spring 70's lower extreme supports in the bottom of handle 11, and spring 70's upper end supports on spacing seat 60, and spacing seat 60 is fixed on connecting rod 40, through sixth screw 96 fixed connection between spacing seat 60 and the connecting rod 40. In the normal state, the spring 70 is in a half-compressed state, and the spring 70 presses the limit seat 60, so that the connecting rod 40 moves up to the maximum displacement.
The hinge 50 is arranged in the base 12, the lower side of the connecting rod 40 is fixedly connected with the rotating shaft of the hinge 50 through a fourth screw 94, the hinge 50 is unfolded to two sides, the magnet 80 is fixed on the lower side of the hinge 50, and the magnet 80 is fixedly connected with the hinge 50 through a fifth screw 95. The upper shell section of the base 12 is trapezoidal so that the hinge 50 can be received over the base 12 in a normal state.
Preferably, both sides of the hinge 50 are provided with hinge hooks 51, the inner surfaces of both sides of the base 12 are provided with hook sliding grooves (not shown in the figure, the same applies below), the hinge hooks 51 are sleeved in the hook sliding grooves and slide along the hook sliding grooves, the hinge 50 is ensured to slide more smoothly in the vertical sliding process, the magnetic attraction degree is further ensured to be more uniform and stable, and the impulsive force to the display screen module is reduced.
In this embodiment, the flannelette 13 is disposed on the lower surface of the base 12, so that the tool and the LED light surface achieve a soft contact protection effect, and damage to the display screen module is further reduced.
The implementation principle of the invention is as follows:
as shown in fig. 1, in a normal state where not in use, both the hinge 50 and the magnet 80 are inclined due to the urging force of the spring 70, this state weakens the magnetic field of the magnet 80 to the outside (magnet characteristics), that is, the attractive force to the outside is weak.
As shown in fig. 2-3, when the tool is used, the index finger is lightly pressed on the first button 21, then the bottom of the base 12 is close to the display screen module, and the flannel 13 on the base 12 is connected with the display screen module, so that the display screen module is not damaged at all; releasing the index finger while the thumb presses the second button 22, the magnet 80 is lowered as it approaches the display screen module, the suction force is increased as the elastic force (reaction force) of the spring 70 is increased, so that the magnet 80 does not directly impact the display screen module; after the magnet 80 reaches the bottom surface of the base 12, the inclined surface of the hinge 50 drives the magnet 80 to open to two sides and turn into a plane due to the guiding effect of the hook chute, and at the moment, the magnetic force of the magnet 80 on the display screen module is maximum, so that a tool can be pulled up to drive the display screen module to move, and the display screen module is separated from the box body.
After the display screen module is separated from the box body, the front maintenance tool and the display screen module are separated, the first button 21 is only needed to be arranged by an index finger, the hinge 50 can rotate with the magnet 80 and generate a labor-saving lever with the base 12, the magnet 80 can be lifted easily by adding the elastic force (reaction force) of the spring 70, the front maintenance tool is restored to the original state, and the display screen module can be taken off from the tool easily.
Each link in the whole disassembly process can well protect the display screen module, so that the maintenance cost of the display screen module is reduced; the invention has simple operation, saves time and labor, reduces the technical requirements for operators and reduces the labor cost.
