To achieve these goals, the utility model is to realize by the following technical solutions：A kind of receiver is dust-proof
Cushion, including dust-proof cushion and receiver, the dust-proof cushion are arranged on the inside of receiver mounting bracket, and under dust-proof cushion
Side is provided with gross porosity web plate, and the two bottom sides of the gross porosity web plate are mounted on baffle plate, and the receiver is pacified installed in receiver
The inner bottom shelved, and cover plate is provided with above receiver mounting bracket, one end of the cover plate are provided with protrusive board, it is described by
Lock is installed at the upper side of words device mounting bracket, offers the second dead slot inside one end of the lock, the lock it is another
Portable plate is installed, the other end of the portable plate is provided with slide block inside one end.
Preferably, the middle position of the lock offers the first dead slot.
Preferably, the lock offers through hole at slide block.
Preferably, the cover plate is rotatablely connected by hinge and receiver mounting bracket one end.
Preferably, one end of the portable plate is provided with the first raised line.
Preferably, the second raised line is installed at the top of second dead slot.
The beneficial effects of the utility model：A kind of dust-proof cushion of receiver, first, on the basis of original, has additional one
Layer gross porosity web plate, by the dustproof effect of bilayer, the clean of receiver working environment is ensure that well, at the same it is dust-proof changing
During cushion, gross porosity web plate can play protective effect well, prevent the magazines such as dust from falling directly into receiver, well for
Receiver provides a clean working environment of safety；Secondly, the top of the receiver mounting bracket is provided with by a hinge
Cover plate, and cover plate is grid type cover plate, covers tightly dust-proof cushion by cover plate, can play a part of tentatively protecting, on the one hand
It can prevent dust-proof cushion from slipping well, on the other hand by latching connecting cover plate, dismounting is more convenient, so as to convenient to anti-
The replacing of dirt cushion.
