Abstract

The utility model discloses a predictive maintenance structure of an LED display screen. The predictive maintenance structure comprises a bottom housing with a magnet, a circuit board mounted with LED lamps, and a cover, wherein metal posts with internal threads are fixed on four corners of the bottom housing; screw holes are formed on the cover and the circuit board in positions corresponding to the metal posts; and screws fitting the threads of the metal posts pass through the screw hole to sequentially fix the cover and the circuit board on the metal posts on the bottom housing. The utility model also discloses a special maintenance tool of the predictive maintenance structure. An LED display screen module to be maintained can be conveniently detached from a back frame by screwing threaded rods of two special tools into the metal posts, thereby preventing the LED display screen module from damaging.

Description

Enclosed structure and special-purpose maintenance tool thereof before the LED display

Technical field

The utility model relates to LED display, relates in particular to the instrument of preceding enclosed structure of a kind of LED display and special-purpose maintenance thereof.

Background technology

LED display has been widely used in various occasions at present, as a kind of electronic product, As time goes on, these LED display will break down or aging problem inevitably, therefore, the mode of safeguarding should be the important content that present LED display circuit and structure are considered when design, safeguard before the maintenance mode of LED display has usually and after safeguard dual mode.

The preceding maintenance mode of existing indoor LED display is at the magnetic column that is equipped with on the LED display module more than 4, utilize the magnetic of magnet that the LED display module is adsorbed on casing or the back of the body frame one by one, when needs are safeguarded, utilizing the slit at blade or screwer edge between the LED display module that the display screen module is prized again overhauls, such mode is easy to damage the display screen module, and must reserve the slit of certain width when mounted between the display screen module, otherwise when maintenance, just be difficult to the display screen module is taken off from back of the body frame front, this slit can have a strong impact on the attractive in appearance and effect of entire display screen integral body, if do not stay the slit, when maintenance, by force the display screen module is prized and just damage the display screen module probably, even understand, thereby cause subsiding of whole screen unit because destroy the magnetism intensity and the balance of display screen module magnet.

Therefore, how to be implemented in when safeguarding before the LED display, can conveniently the display screen module be taken off from back of the body frame front is a technical matters that needs to be resolved hurrily in the industry.

The utility model content

The utility model is will solve when safeguarding before LED display, can conveniently the display screen module be taken off the technical matters that can't damage the display screen module from back of the body frame front.

For solving the problems of the technologies described above, the utility model proposes the preceding enclosed structure of a kind of LED display, comprise the drain pan of carry magnet, the circuit board that the LED lamp is installed and face shield, wherein: on four angles of this drain pan, be set with tapped metal column, on described face shield and circuit board, offer screw hole with the corresponding position of this metal column, be provided with this metal column in the suitable screw rod of screw thread, this screw rod passes this screw hole and successively face shield, circuit board being fixed on the metal column of this drain pan.

Corresponding position is respectively arranged with a plurality of screw holes on described face shield, circuit board and the drain pan, and the drive screw suitable with this screw hole is fixed together this face shield, circuit board and drain pan successively.

The utility model has also proposed the special-purpose maintenance tool of the preceding enclosed structure of a kind of LED display, and it comprises: the screw thread in handle, the threaded rod of fixedlying connected with this handle, the screw thread on this threaded rod and this metal column is suitable.

Compared with prior art, the utility model has increased the maintenance tool of 4 tapped metal columns and two special uses on four angles at drain pan on original product basis, threaded rod with two special-purpose maintenance tools screws in the metal column, the LED display module that can will keep in repair easily takes off from back of the body frame, reserving gaps more just between the LED display module, solved safeguard that long-term existence display screen module is damaged easily before the indoor in the market LED display and the display screen module between want the technical matters of reserving gaps, alleviate maintenance personal's work difficulty, increased the aesthetic measure and the display effect of LED display integral body.

Description of drawings

Below in conjunction with drawings and Examples the utility model is made detailed explanation, wherein:

Fig. 1 is the view of the utility model preferred embodiments drain pan;

Fig. 2 is the synoptic diagram of the special-purpose maintenance tool of the utility model preferred embodiments;

Fig. 3 is the exploded view of the utility model LED display module preferred embodiments.

Embodiment

As Fig. 1, shown in Figure 3, be enclosed structure before the LED display of preferred embodiments, the drain pan 1 that comprises carry magnet, the circuit board 2 and the face shield 3 of LED lamp are installed, on four angles of this drain pan 1, be set with tapped metal column 11, guaranteed repeatedly dismounting and can not slide tooth and damage of standing screw, this metal column 11 can be copper, the post that metals such as iron are made, on four angles of face shield 3 and circuit board 2 with this suitable screw hole that offers in metal column 11 corresponding positions, with the suitable screw rod 4 of the screw thread in the metal column can the precession metal column in, screw rod can be selected the M2 screw rod for use, screw rod 4 pass on four angles of face shield 3 and circuit board 2 screw hole and successively with face shield 3, circuit board 2 is fixed on the metal column 11 of this drain pan.

The special-purpose maintenance tool of enclosed structure comprises handle 5 and the threaded rod 6 of fixedlying connected with this handle before the LED display, anti-skidding burr is arranged on the handle 5, prevent to skid in use, screw thread in screw thread on the threaded rod and the metal column 11 is suitable, threaded rod can be screwed in the metal column 11, conveniently to take off display screen to be keeped in repair.

Corresponding position is respectively arranged with a plurality of screw holes on face shield 3, circuit board 2 and the drain pan 1, become an integral body with successively this face shield 3, circuit board 2 and drain pan 1 being fixed together with the suitable drive screw of screw hole, this drive screw adopts usual M2 tapping screw thread, is unlikely to face shield 3 after taking off screw rod 4 like this when keeping in repair and circuit board 2 can fall down.

The flow process in the utility model when maintenance is: at first two M2 standing screws with the LED display module diagonal angle that needs repairing take off with general screwer, the fixed orifice of vacating on the special-purpose maintenance tool precession LED display module diagonal angle with two customizations then, the copper post of band M2 internal thread on threaded rod 6 and the drain pan 1 is connected, both hands are firmly grasped the handle 5 of two special-purpose maintenance tools again, on the direction of vertical and display panel, pull out the LED display module that needs repairing outward, after repairing the fault on the LED display module, load onto the M2 screw rod of pulling down, the screen group is put back to the origin-location.

The utility model can be widely used in the indoor LED display of all size, as: P4, P5, P6, P7.62, P8, P10, P12 etc., for installation, maintenance and the project acceptance inspection of safeguarding LED display before indoor provides a great convenience.
