Display screen anti-loosening buckle mechanism

Abstract

The invention provides a display screen anti-loosening buckle mechanism which comprises a front casing and a rear casing. The front casing is in buckled connection with the rear casing. The front casing is internally provided with a first groove, the first groove is fixedly connected with a ball column, the rear casing is internally provided with a second groove, the second groove is fixedly connected with a sleeve, and the sleeve is in buckled connection with the ball column. The top of the front casing is provided with an outer edge, the top of the rear casing is provided with an inner edge,the outer edge is internally provided with a groove, the groove is internally fixedly connected with a flexible limiting ring, and the top of the groove is fixedly connected with a conical groove. The inner edge is in threaded connection with the bottom end of a buckle head, and the top end of the buckle head passes through the flexible limiting ring and then extends into the conical groove. According to the display screen anti-loosening buckle mechanism, the front casing and the rear casing can be completely sealed through the buckled connection of the ball column, the sleeve, a unilateral buckle and a buckle groove; and through the sleeved connection of the buckle head and the flexible limiting ring and by means of the buffer effect of the flexible limiting ring, the peristaltic motionbetween the front casing and rear casing after assembly is reduced.

Description

Technical field [0001] The invention relates to the technical field of on-board display screens, in particular to a display screen anti-loosening buckle mechanism. Background technique [0002] The buckle is a coordinated configuration of the positioning member, the locking member and the reinforcing member to form a mechanical connection between the parts. Plastic buckles are now widely used in various fields such as toys, auto parts, and home appliances. Generally, buckles have a common feature, which is composed of a combination of a locking piece and a positioning piece. The shape of the buckle is various, whether it is a hip or a ring, their functions are the same, restraint and separation. [0003] The buckle does not require other materials, which can reduce product costs; simple operation; it has the function of replacing expensive metal parts such as screws, nuts and washers; it is suitable for the assembly of general plastic parts; there are no complicated technical req...
