Background

The LED display screen is difficult to maintain and becomes a pain point for many users, and the overhauling and maintenance work becomes very difficult for the users adopting embedded type and wall-mounted type installation.

The maintenance mode of the LED display screen mainly comprises front maintenance and rear maintenance, the great characteristic of the front maintenance is that the space is saved, and the space is extremely precious for indoor or embedded or wall-mounted structures, so that excessive places can not be left as maintenance channels. The overall thickness of the LED display screen structure can be greatly reduced through previous maintenance, the LED display screen structure can be well integrated with the surrounding building environment, and the space can be saved while the effect is ensured. However, this structure has very high requirements for the heat dissipation function of the device; the great benefit of after-maintenance lies in that the price is slightly low, is fit for installation scenes such as roof formula, column, etc. and the inspection is maintained convenient high-efficient. For large-scale LED display screens installed on the outer walls of buildings, a maintenance channel needs to be designed, and maintenance personnel can maintain and overhaul the screen body from the back.

The current LED module maintenance lock can only carry out front maintenance or rear maintenance, and can not carry out both front maintenance and rear maintenance, so the application range is not wide, the unlocking and locking operation is complex, and the maintenance is inconvenient.

When the front and back maintenance lock structure of the existing LED display screen is locked, the stress is eccentric, so that a screw for fixing the lock is subjected to a drawing force for a long time, the service life of the screw is influenced, and the maintenance lock is easy to loosen; the front and back maintenance lock structure of the existing LED display screen can not meet the protection grade requirement of a fully-closed IMPCB plate, the internal and external air pressure is difficult to balance, and the moisture is easy to permeate; the shell is fixed by the self-tapping teeth, and the shell can be loosened after being disassembled and assembled for a plurality of times, so that the locking effect is poor.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to above-mentioned prior art not enough and provide a module of LED display screen maintains the lock structure around fast, solved through maintaining the lock around on the shell and realize front maintenance and back maintenance, the lock is maintained to the fastening is fixed, inside and outside atmospheric pressure of balance, prevent to get into the technical problem of moisture.

The utility model discloses a solve the technical scheme that above-mentioned problem adopted and do:

the utility model provides a module of LED display screen maintains keying structure around fast, the insulated metal printing board of LED display screen sets up between preceding maintenance backplate and shell, and the maintenance hole before having arranged on the preceding maintenance backplate, the four corners equipment of shell maintain the lock around having, and the centre of shell is assembled there is the lid, and the top surface of lid is equipped with pilot lamp structure and airtight test hole, and the side of lid is equipped with airtight stopper and respirator.

Further, the lid is equipped with four trapezoidal sides and top surface, the base of lid is connected with the chimb, in the chimb gomphosis is in the recess on the shell.

Further, maintain including panel beating base, maintenance hole post, column spinner and spring on the lock around, maintain on the hole post wears to establish and is fixed in the panel beating base, the column spinner sets up in maintaining hole post upper end, and the both ends of rotatory crooked spring are fixed in respectively and maintain hole post upper and lower extreme.

Further, the pilot lamp structure includes transparent lid, pilot lamp PCB board and O type sealing washer.

Further, an armrest is assembled on the housing.

Furthermore, the shell is provided with a screw column for fixing the cover body or the handrail, and the screw column is formed by encapsulating a copper column in a mould.

The utility model discloses the module of LED display screen maintains around quick that the beneficial effect of keying constructs lies in:

the utility model realizes front and back maintenance through four quick maintenance locks, realizes back maintenance through maintenance tools during front maintenance, and directly screws the cross rod on the quick maintenance lock for back maintenance; during post maintenance, the four front maintenance holes are inserted into the holes by a maintenance tool, and the quick lock is rotated to realize front maintenance, so that the front and rear maintenance operations are convenient and the use is convenient; the utility model discloses still have the fixed technical effect who maintains the lock, balanced inside and outside atmospheric pressure, prevent to get into moisture of fastening.
