Description

Display screen box installation fixing device and display screen Technical Field The utility model belongs to the technical field of display screens, and particularly relates to a display screen box body mounting and fixing device and a display screen. Background With the rapid development of modern technology, large-scale LED display screens are widely applied in various fields such as advertising, information display, stage performance and the like. The large-scale LED display screen is usually formed by splicing a large number of single display screen boxes, and the design rationality and stability of the installation fixing structure play a vital role in whether the display screen can be normally used and the safety. In the conventional mounting and fixing manner of the display screen case, the fastening angle is generally formed by combining a U-shaped fastening angle 10 with a straight fastening angle 11, and the fastening angle is fixed on the fixing rod 1 by installing bolts at four corners, etc., and the specific structure can be referred to fig. 1. However, in practical application scenarios, especially for high-height display screen bodies, this mounting exposes a series of significant problems. First, the number of parts involved in the conventional mounting method is large, and each part is manually assembled and fixed. In the assembly process, there often occurs a case where a part of the bolts are inserted into the corresponding mounting holes, but are not yet completely fastened. At this time, the worker operates under the high-altitude operation environment, and the space is narrow and the operation degree of difficulty is big, and slight rocking or careless touching of health all very easily lead to these parts that do not fasten in place to become flexible and drop. Moreover, the gasket is required to be penetrated on the bolt, and then the bolt with the gasket is inserted into the corresponding mounting hole, however, when an operator works at high altitude, the gasket is easily and accidentally dropped due to the influence of factors such as shaking hands and the like. The risk of high-altitude falling of the parts not only forms serious threat to the safety of personnel and equipment below, but also causes forced interruption of the installation progress once falling accidents occur, thereby increasing construction cost and bringing great potential safety hazards. Secondly, the combination of numerous spare part has greatly increased the degree of difficulty of high altitude construction. Under the high altitude environment, the workers need to accurately position and install all parts and finish fine operations such as screwing bolts, so that manual operation is very inconvenient, the installation flow is tedious and tedious, a large amount of manpower and time cost are required to be consumed, and the installation efficiency is low.
