Abstract

The utility model discloses a middle frame structure 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 a plurality of rubber bumps which are arranged into an array at positions close to a front edge and a rear edge of the middle frame opening. The middle frame structure 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

A kind of middle mount structure of learning machine shell

Technical field

The utility model relates to learning machine shell field, is specially a kind of middle mount structure 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 middle mount structure 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 middle mount structure 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, was respectively arranged with a plurality of rubber salient points near position, the forward and backward edge of middle boxes mouth on the framework, and on the framework near a plurality of rubber salient points at the forward and backward edge of middle boxes mouth respectively ranks be arranged in array.

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; Be easy to realize; On framework, be respectively arranged with a plurality of rubber salient point ranks and arrange the rubber convex lattice array that constitutes near position, the forward and backward edge of middle boxes mouth; Circuit board is pressed on the rubber convex lattice array, does not directly contact with middle circle face, can effectively alleviate in the use wearing and tearing to circuit board through the rubber salient point.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

As shown in Figure 1.A kind of middle mount structure of learning machine shell; Include framework 1, have middle boxes mouth 2 in the middle of the framework 1, framework 1 rear end is bent upwards and constitutes bend 3; And hollow out in the middle of framework 1 bend 3; Bend 3 tops were connected with line tube 4, were respectively arranged with a plurality of rubber salient points 5 near position, middle boxes mouth 2 forward and backward edge on the framework 1, and on the framework 1 near a plurality of rubber salient points 5 at middle boxes mouth 2 forward and backward edges respectively ranks be arranged in array.Also be provided with a plurality of installation through holes 6 near the position, edge on the framework 1.
