Description

Easily-detachable shielding cover Technical Field The utility model relates to the technical field of shielding covers, in particular to an easily-detachable shielding cover. Background The shielding cover is a metal or metalized component used in electronic equipment, is usually made of materials with good electromagnetic shielding performance such as copper, aluminum, iron-nickel alloy and the like, can prevent electromagnetic radiation generated by internal electronic elements from leaking into the external environment, avoids electromagnetic interference to other surrounding electronic equipment, can prevent external electromagnetic signals from entering the equipment, prevents interference to internal sensitive electronic elements and ensures normal operation of the equipment. The existing shielding cover is generally installed on the shielding shell by adopting screws or other rigid connection modes, so that the screws are required to be screwed one by one when the shielding cover is installed, the screws are required to be unscrewed one by one when the shielding cover is detached, the process is complex, the consumed time is long, and especially for some large-scale equipment or electronic equipment with complex internal structure, the number of the screws is more, and the time cost for installing and detaching is higher. Disclosure of utility model The utility model aims to solve the technical problems that in the prior art, the connection mode of a shielding cover and a shielding shell is complex, so that the mounting and dismounting are needed to take more time. In order to achieve the purpose, the application adopts the following technical scheme that the quick detachable shielding cover comprises a shielding shell, wherein a shielding cover main body is arranged at the bottom end of the shielding shell, four fixing plates are fixedly connected to the top end of the shielding cover main body, limiting openings are formed in the surfaces of the fixing plates, four fixing blocks are arranged on the surfaces of the shielding shell, pressing grooves are formed in the fixing blocks, elastic springs are fixedly connected to the inside of the pressing grooves, pressing blocks are fixedly connected to the tail ends of the elastic springs, and the limiting openings and the inside of the pressing grooves are in sliding connection with the pressing blocks. Preferably, the two sides of the pressing groove are provided with stop grooves, the two sides of the pressing block are fixedly connected with stop blocks, and the inside of the stop grooves is in sliding connection with the stop blocks. Preferably, the surface of the pressing block is provided with an inclined plane. Preferably, four guide grooves are formed in the bottom end of the shielding shell, four guide blocks are arranged at the top end of the shielding cover main body, and the inside of each guide groove is in sliding connection with each guide block. Preferably, glass observation windows are arranged at the front end and the rear end of the shielding shell, and transparent metal films are covered on the surfaces of the glass observation windows. Preferably, the top end of the shielding shell is provided with radiating fins, and the radiating fins are a plurality of and uniformly distributed on the top end of the shielding shell. The utility model has the technical effects and advantages that: According to the utility model, when a worker needs to detach the shielding cover main body, the four pressing blocks are simultaneously pressed inwards, so that the shielding cover main body and the shielding shell can be detached, at the moment, the shielding cover main body can be detached, when the shielding cover main body needs to be installed back on the shielding shell, the pressing blocks are pressed inwards again, the shielding shell and the shielding cover main body are aligned and attached, the elastic force of the elastic spring drives the pressing blocks to pop out of the limiting opening after the pressing blocks are completed, the shielding shell and the shielding cover main body can be quickly fixed, and when the electronic equipment breaks down, a technician can quickly detach the shielding cover main body from the shielding shell, quickly position and overhaul internal electronic elements without spending a great deal of time on detaching complex fixing structures, so that the maintenance time is shortened, and the usability of the equipment is improved.
