Abstract
The utility model discloses a middle frame of a learning machine casing, comprising a frame body; wherein a middle part of the frame body is provided with a middle frame opening, a middle part of a bending part at a rear end of the frame body is hollowed out, a top end of the bending part is connected with a wire passing cylinder, and the frame body is respectively provided with rubber strips which are connected into a whole around the middle frame opening. The middle frame of the utility model has a simple structure and easy realization, and can avoid direct contact between a circuit board and a frame surface of the middle frame, thereby reducing wearing of the circuit board, and prolonging a service life of a learning machine.
Description
Technical field
The utility model relates to learning machine shell field, is specially a kind of center of learning machine shell.
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, battery cover etc.The center of learning machine generally has the middle boxes mouth, and its keyboard of circuit board that has keyboard passes the middle boxes mouth of center, and circuit board is pressed on the center.The circle face directly contacts with circuit board in the prior art learning machine, and service time, length was prone to cause circuit board wearing and tearing, the normal use of the machine that interferes with one's studies.
The utility model content
The utility model purpose provides a kind of center of learning machine shell, directly contacts with middle circle face with solution prior art learning machine circuit board to be prone to cause the circuit board wear problems.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of center of learning machine shell; Include framework, it is characterized in that: have the middle boxes mouth in the middle of the said framework, the framework rear end is bent upwards the formation bend; And hollow out in the middle of the framework bend; The bend top was connected with the line tube, be positioned on the framework to be respectively arranged with rubber strip around the middle boxes mouth, and the rubber strip frame around the middle boxes mouth to connect be that one constitutes the shaped as frame structure.
The center of described a kind of learning machine shell is characterized in that: also be provided with a plurality of installation through holes near the position, edge on the said framework.
The utility model is simple in structure, is easy to realize, rubber strip is set around the middle boxes mouth of framework; Rubber strip frame each other connects formation shaped as frame structure; Circuit board is pressed on the rubber strip, does not directly contact with middle circle face, can effectively alleviate in the use wearing and tearing to circuit board through rubber strip.The utility model can avoid circuit board directly to contact with middle circle face, has reduced the wearing and tearing of circuit board, has improved the useful life of learning machine.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
