Detailed Description

The lockhole of current drain pan can't deal with screw fracture in the installation, leads to unable fastening PCB board and the follow-up condition of dress screen unevenness, and then leads to whole module to scrap, causes the problem of extravagant cost. Therefore, the present invention provides a new solution, and for a clearer representation, the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1-5, the bottom shell of the small-spacing LED display screen comprises an outer frame 10, wherein an inner edge 20 and an inner frame 30 are arranged in the outer frame 10. The outer frame 10, the inner rim 20 and the inner frame 30 are connected to each other.

The outer frame 10 is a rectangular frame, and the inner frame 30 includes a plurality of transverse frames arranged at intervals and a plurality of longitudinal frames arranged at intervals. In this embodiment, the inner frame 30 includes two transverse frames disposed at intervals, and three longitudinal frames disposed at intervals, wherein one of the longitudinal frames has a width twice that of the other two longitudinal frames, and is disposed at a central axis position in the outer frame 10.

The inner frame 30 is provided with an arrow mark, which is provided on the longitudinal frame in the middle position. The arrow mark is a fool-proof design, can play an indicating role when the circuit board is installed, and prevents reverse installation.

A reinforcing rib 80 is provided between the outer frame 10 and the inner edge 20 to reinforce and fix the whole bottom case.

A plurality of first lock columns 40 are arranged on the inner edge 20 and the inner frame 30 at intervals, first lock holes 41 used for locking the PCB are arranged in the first lock columns 40, second lock columns 50 are arranged at four corners of the inner edge 20, and second lock holes 51 and standby holes 52 used for locking the PCB are arranged in the second lock columns 50. The number of the first lock cylinder 40 and the first lock hole 41 is set according to actual needs. The second lock hole 51 and the spare hole 52 are distinguished by names only, and the relative positions thereof are not particularly limited.

The PCB is provided with a third locking hole corresponding to the first locking hole 41, the second locking hole 51 and the standby hole 52, and a screw penetrates through the corresponding locking holes on the PCB and the bottom shell to lock and fix the PCB and the bottom shell, so that the subsequent display screen can be conveniently installed.

The first locking hole 41, the second locking hole 51 and the spare hole 52 are all equal in size and oval in shape, and the major axis direction of the oval locking hole is parallel to the length direction (i.e., transverse direction) of the outer frame 10. The oval lockhole can avoid the drain pan expend with heat and contract with cold to arouse its drain pan and PCB's hole decentraction, and then leads to the lock to pay the screw fracture.

The inner edge 20 is provided with a plurality of positioning columns 60. The positioning column 60 can limit the position of the PCB when the PCB is put on the bottom case, so that subsequent screws can be locked conveniently.

The outer side wall of the outer frame 10 is provided with a groove 70, and the outer side wall is fixed with an aging jig through the groove 70 in the aging process of the LED module.

The utility model discloses be equipped with spare hole 52 around the drain pan, after the cracked condition of screw appears in the installation when the PCB board, can utilize spare hole 52 all around with PCB board fixed mounting, guarantee that the PCB board can not be because not locking and perk, and then guarantee the planarization of follow-up dress screen, can not make whole module scrap because of the screw fracture.

The utility model discloses can the wide application in the booth apart from LED display screen drain pan, can effective reduction in production cost.

The above embodiments are only used for explaining the technical solution of the present invention and not for limiting the same, and although the above embodiments are specific to the present invention, it should be understood by those skilled in the art that the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the present invention, which should be covered by the claims of the present invention.
