Abstract

The invention discloses a box-type theft-proof front maintenance bracket for an LED (Light Emitting Diode) display screen. The box-type theft-proof front maintenance bracket comprises a unit plate (1), a box (2) and a theft-proof mechanism, wherein a groove (9) is formed at the upper end of a unit plate connecting sheet (7), a clamping slot (10) is formed on the side of a clamping strip (8) and located at the upper end of the clamping strip (8), the clamping strip (8) is provided with a kidney-shaped hole (11), a screw B (12) penetrates through the kidney-shaped hole (11) and is connected with a threaded hole to fix the clamping strip (8) onto the box (2), a limiting column (6) is composed of a small shaft (13) and a big shaft (14), the small shaft (13) is perpendicular to the clamping strip (8) and is riveted onto the clamping strip (8) and arranged in the groove (9), and the big shaft (14) is arranged between the unit plate connecting sheet (7) and the unit plate (1). The box-type theft-proof front maintenance bracket has the advantages of compact structure and theft-proof function, and is convenient for an operator to maintain or replace unit modules of the LED display screen from the front side.

Description

technical field [0001] The invention relates to the technical field of anti-theft LED display screens, in particular to a box-type anti-theft front maintenance bracket for LED display screens. Background technique [0002] LED display has been widely used in many public places. Existing LED display screens are composed of several LED boxes spliced ​​together to form a whole. Most LED displays use the rear maintenance method of the cabinet, and the rear maintenance method is inconvenient to operate. Therefore, the front maintenance method is often used, and the LED display can be removed from the front. The LED display is usually fixed and installed on the maintenance tray by magnetic suction. On the shelf, however, the electromagnet is easy to be destroyed artificially, and the whole LED display screen is easy to be stolen after being destroyed, and does not have anti-theft function. [0003] In order to prevent the LED display from being destroyed or stolen, the Chinese p...
