Abstract
The utility model discloses a cover plate structure of a battery of a learning machine. The cover plate structure comprises a covering body. A rectangular frame is disposed in the covering body. The rectangular frame is provided with four sealing gaskets clung to the inner wall of the rectangular frame. The four sealing gaskets are successively connected end to end to form a sealing frame. The cover plate structure is simple, easy to be realized, helps to effectively prevent dust from entering to cause contact failure of a battery, and enables the service life of the battery of a learning machine to be improved.
Description
Technical field
The utility model relates to learning machine shell field, is specially a kind of learning machine battery cover board structure.
Background technology
Learning machine is a kind of electronic instruction series products, is widely used in the student group at home.The learning machine shell generally is made up of center, base plate, cover plate etc., and the circuit of learning machine is arranged in the space that center, drain pan, cover plate surround, and in center, is provided with the battery of power supply.Learning machine is long service time, can get into dust in the center, is prone to cause the battery loose contact, influences the power supply of battery to learning machine.
The utility model content
The utility model purpose provides a kind of learning machine battery cover board structure, is prone to the problem that ash into causes loose contact to solve prior art learning machine long battery service time.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of learning machine battery cover board structure includes lid, in lid, is respectively arranged with a plurality of fixture blocks on the sidewall around the said lid; Be provided with vertical locating piece between the fixture block of covered body wall; It is characterized in that: be provided with rectangle frame in the said lid, be provided with four diaphragm seals in the rectangle frame, said diaphragm seal respectively one by one correspondence be close to rectangle frame four side inwalls; The diaphragm seal height is higher than rectangle frame, and four diaphragm seals connect and compose the sealing frame successively from beginning to end.
The utility model is simple in structure, is easy to realize that after battery cover board covered, rectangle frame and center were involutory, embeds through diaphragm seal then to constitute sealing in the center, can cell sealing be lived, and the control dust gets into from rectangle frame and center apposition position slit.The utility model can prevent effectively that dust from getting into the problem that causes the battery loose contact, the serviceable life of having improved the learning machine battery.
