  "claims": [
    "1. A display apparatus, comprising a display panel, a front bezel, a back plate, and a connection structure, wherein the front bezel is fixedly connected to the back plate through the connection structure, and the connection structure comprises: a connection column, comprising two end portions, wherein a guide groove is formed between the two end portions of the connection column; a base, fixedly connected to one of the two end portions of the connection column; an elastic arm, fixedly connected to the other of the two end portions of the connection column; an elastic member, fixedly connected to a side face of the base facing the elastic arm; and a snap ring, sleeved over the elastic arm, wherein an engagement member is arranged on the snap ring, the engagement member is accommodated in the guide groove, and the engagement member moves in the guide groove under an action of an external force, to drive the snap ring to reciprocate along a direction of the guide groove, wherein an acting force acting on the elastic arm is generated by moving the snap ring, to enable the elastic arm to elastically deform and change an open/close angle between the elastic arm and the connection column; and a clamping groove is formed on an end of the guide groove proximal to the base, and when the engagement member moves to the clamping groove, the engagement member is engaged to the clamping groove; and wherein through-holes having a same size are formed on the front bezel and the back plate, and the connection structure is arranged in the through-holes in a penetrating manner; wherein when the engagement member moves to the clamping groove, the engagement member is engaged to the clamping groove, and diameters of the through-holes are larger than a maximum outer diameter of the snap ring; and wherein when the engagement member is not located at the clamping groove, and a maximum outer diameter of a circle formed by the elastic arm with the connection column as a circle center is larger than diameters of the through-holes.",
    "2. The display apparatus according to claim 1, wherein the connection column is perpendicularly connected to the base.",
    "3. The display apparatus according to claim 1, wherein a quantity of the elastic arms is two, and the two elastic arms are symmetrically connected to the connection column.",
    "4. The display apparatus according to claim 1, wherein the elastic member is conductive foam."

  "description_excerpt": "This application relates to the field of display technologies, and in particular, to a connection structure and a display apparatus.\n\nWith development of flat panel display technologies, a display effect of a flat panel display is greatly progressed. Compared with conventional cathode ray tube screens, flat panel displays have advantages such as a small weight, a small volume, and low radiation. In addition, progress in manufacturing processes and technologies reduces costs of flat panel displays, and therefore the flat panel displays are favored by a large number of consumers in the market. Common flat panel displays include Plasma Display Panels (PDPs), Liquid Crystal Displays (LCDs), Organic Light-Emitting Diodes (OLEDs), and the like. Because of advantages such as improved picture quality, a shortened response time period, relatively low costs, and a relatively long service life, the LCDs gradually become mainstream flat panel displays in the market.\n\nIn a process of manufacturing an LCD, assembly of respective modules consumes huge manpower costs. For example, respective components of an LCD are usually connected by locking screw pairs, and it is difficult to assemble or disassemble the components in a production or maintenance process, resulting in problems such as large time consumption and high production costs.\n\nThis application provides a connection structure having higher convenience and a display apparatus.\n\nAccording to an aspect, an embodiment of this application provides a connection structure, comprising:",
