Description

Network set top box main board assembly convenient to detach Technical Field The utility model relates to the technical field of network set top box mainboards, in particular to a network set top box mainboard assembly convenient to detach. Background Network set-top boxes are vital technical devices in information appliances. The functionality of set-top boxes has been stepped from a multi-frequency tuner and decoder to a control terminal for online databases of large numbers of movies, multimedia events, news, etc. The internal main board of the set top box is the heart of the set top box and bears the operation of all functions of the set top box; In the prior art, when the main board of the set top box needs to be overhauled, a worker firstly has to disassemble the shell of the set top box completely, and after the shell is disassembled, as the main board is usually fixed inside the set top box through a plurality of bolts, the worker needs to screw out the main board one by using matched tools, in the process, the worker needs to pay attention to avoiding the loss of the bolts due to falling, and the main board is prevented from deforming or welding spots from falling due to uneven force, so that the preparation time for overhauling is obviously prolonged, and therefore, the main board assembly of the network set top box is provided, which is convenient to disassemble. Disclosure of Invention The utility model aims to provide a network set top box main board assembly convenient to detach so as to solve the problems in the background technology. In order to achieve the above purpose, the utility model provides a network set top box main board component convenient to detach, which comprises a first shell, a second shell and a main board body, wherein a circular connecting port is formed on the right side of the rear end of the first shell, a heat dissipation groove is formed on the outer part of the first shell, and the network set top box main board component further comprises: The limiting component is arranged in the second shell and is used for fixing the main board body; The positioning assembly is arranged on the two inner walls of the shell and is used for positioning when the main board body is installed. Wherein, spacing subassembly includes the mounting groove, and an inside fixedly connected with telescopic link of shell, telescopic link outside cover are equipped with the spring, telescopic link bottom fixedly connected with stop collar, and the stop slot has been seted up to the stop collar inside. Wherein, locating component includes the backing sheet, and locating component inside is provided with magnetic sheet one, and mainboard body bottom fixedly connected with two mounting plates, mounting plate inside is provided with magnetic sheet two. Wherein, shell one bottom is provided with fixed subassembly, and fixed subassembly inside threaded connection has the gim peg, and shell one inside fixedly connected with fixed block, gim peg outside threaded connection is inside the fixed block. Wherein, the four corners of the two bottoms of the shell are fixedly connected with supporting pads. The first connector is arranged outside the first shell, and the second connector is arranged on the left side of the rear end of the first shell. The inside of the limiting groove is contacted with the outside of the limiting assembly, one side of the spring is fixedly connected with the outside of the limiting sleeve, and the other side of the spring is fixedly connected with the inside of the first shell. The utility model has at least the following beneficial effects: When the positioning assembly is used, the first magnetic sheet and the second magnetic sheet of the positioning assembly are mutually attracted, so that the main board body is quickly adsorbed to the correct position, the bolt holes do not need to be repeatedly aligned, the quick installation is convenient, the adsorption force of the magnetic sheets can be easily overcome when the positioning assembly is disassembled, the main board is directly taken out, the tedious process that the traditional bolt is required to be screwed off one by one is avoided, and the overhaul preparation time is shortened; When the fixing bolt is unscrewed, the spring drives the limiting sleeve to reset, the constraint on the main board is relieved, a special tool is not needed in the whole process, the main board can be detached and installed by a single person, meanwhile, the fixing bolt of the fixing assembly penetrates through the second shell to be screwed into the fixing block, the first shell is firmly connected with the second shell, and the fixing block is matched with the limiting sleeve to limit the jacking movement of the main board from the periphery.
