An anti-shock and anti-drop protection device for a digital TV set-top box

Abstract

The invention discloses an anti-shock and anti-drop protection device for a digital TV set-top box. The lower sides of the left and right ends of the casing are hingedly connected with upward rotating rods, and the middle of the upper end of the upper pressure plate is connected with two drawing wires. The upper end of the upper end passes through the upper spring and the support tube in order, and the ends of the two drawing wires penetrate from the left and right sides of the upper end of the casing respectively, and go out from the left and right ends of the inner cavity of the casing to connect with the rotating rod on the corresponding side. . When in use, move the turning plate to both sides, the two turning rods move to the left and right sides, the turning rod drives the wire drawing, and the wire drawing pulls the upper pressing plate upwards. Squeeze the set-top box, under the action of the upper spring and the lower spring, it supports the set-top box. When the shell falls, the upper spring and the lower spring play a shock-absorbing and buffering role, which protects the set-top box well. The set-top box can be removed by directly turning the rotating plate, which is also very convenient to replace and more convenient to use.

Description

technical field [0001] The invention belongs to the technical field of digital television terminal equipment, relates to an anti-dropping device for a digital TV set-top box, and in particular relates to an anti-shock and anti-dropping protection device for a digital TV set-top box. Background technique [0002] A set-top box is a device that connects a TV with an external signal source. It can convert the compressed digital signal into TV content and display it on the TV. With the addition of network functions, the function of the set-top box is becoming more and more powerful. It has become an indispensable household appliance; when the set-top box is used, it is inevitable that there will be accidental collision and accidental fall. The structure of the drop set-top box includes a bottom case, a face case and a circuit board; a plurality of first superior glue posts are arranged at the bottom of the bottom case, the upper end of the first superior glue post is provided wi...

[0002] A set-top box is a device that connects the TV with an external signal source. It can convert the compressed digital signal into TV content and display it on the TV. With the addition of network functions, the function of the set-top box is becoming more and more powerful. Become an indispensable household appliance; when the set-top box is used, it is inevitable that there will be a situation of accidental collision and accidental fall. The structure of the set-top box includes a bottom case, a surface case and a circuit board; there are a plurality of first Youli glue columns on the bottom of the bottom case, and a mounting plate for installing a circuit board is arranged on the upper end of the first Youli glue columns, and a cylinder is arranged on the installation plate There is a via hole matching the docking block on the circuit board; a second Ulyss glue column is arranged on the lower surface of the face shell; a blind hole for accommodating the second Ulyssed glue column is arranged on the upper end of the docking block; when installing, the circuit The board and the mounting plate are fixedly installed, and then the second Ulystic glue column is inserted into the blind hole in alignment, and the upper shell is covered to complete the installation. It absorbs vibrations, prevents damage to the circuit board, and has high protection; the overall structure is simple, easy to install, and low in cost." It is not convenient to disassemble, and it is not convenient to replace when it is broken
