All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In practical applications, the applicant has found that: the existing teaching playing equipment is used for a long time, after the existing teaching playing equipment is dropped unintentionally, the teaching playing equipment is damaged, especially when a naughty student is encountered, the frequency of the damage of the teaching playing equipment is greatly increased, the playing equipment is afraid of water, the student carelessly turns over a water cup to cause the water inlet of the playing equipment in the using process, irretrievable damage to the playing equipment is caused, great trouble is brought to the use of the student, and the following technical scheme is provided for solving the anti-falling performance and the waterproof performance of a teaching machine.
Referring to fig. 1 to fig. 3, the present invention provides a technical solution: an electronic teaching device comprises a shell 1, wherein the shell 1 is an opening and is internally provided with a shell 1 with a containing cavity, the shell 1 is rotatably connected with a door body 2, the door body 2 is provided with a lock body 8, the door body 2 is firmly fixed on the shell 1 and is used for sealing the opening of the shell 1, two opposite side walls of the shell 1 are provided with fixing components 4, the inner wall of the shell 1 opposite to the door body 2 and the inner wall of the door body 2 are respectively provided with a positioning component 5, a teaching machine is fixed in the containing cavity of the shell 1 by mutually matching the fixing components 4 and the positioning components 5, in the process of carrying everywhere, a water body enters the shell 1 due to the moisture or accident to damage the teaching machine in the shell 1, the shell 1 is made of waterproof materials, and the door body 2 is provided with an elastic strip, the elastic strip is along 2 borders of the door body encircle a week, seal door body 2 and 1 contact position of casing, make and further seal between door body 2 and the casing 1, avoid casing 1 interior intaking, cause the damage to the teaching machine.
Fixed subassembly 4 includes a pair of fixed mounting and is in reset spring 41 on the 1 inner wall of casing, every there is clamping plate 42, one of them fixed mounting respectively on reset spring 41 set up dwang 43 on the clamping plate, installation joint axle 44 on the dwang, another set up dead lever 45 on the clamping plate 42, set up recess 46 on the dead lever 45, two clamping plate 42 passes through rotation each other between dwang 43 and the dead lever 45 and connects, and with the mutual mirror symmetry of connecting axle to be in through joint axle 44 joint make two clamping plate 42 carry out the joint in the recess 46 and fix, clamping plate 42 uses the joint axle to rotate as the center, presss from both sides the clamp to fix the intracavity that holds at casing 1 with the teaching machine.
In a further embodiment, the clamping plates 42 on the same side wall can rotate forward by a predetermined angle around the symmetry axis in the length direction thereof, provide a redundant space for the teaching machine to be put in, and rotate reversely after the teaching machine is put in, so as to clamp and fix.
That is, the clamping plate 42 not only has a damping function in the left-right direction under the action of the spring, but also can enable the clamping plate 42 to tilt towards the inner side or the outer side because the spring can tilt towards the inner side or the outer side (i.e. the up-down direction), where the middle of the clamping plate 42 is defined as the inner side and the edge is defined as the outer side, and the edge of the clamping plate 42 is caused to expand or contract towards the inner side or the outer side while tilting, so as to form a movement similar to a V shape. When putting the teaching machine into between joint plate 42, joint plate 42 edge opens up downwards, forms bigger putting into space, is convenient for put into the teaching machine wherein. After the teaching machine is placed in, under the elastic action, the edge of the clamping plate 42 resets and is folded inwards to press the teaching machine tightly, so that the teaching machine is clamped and positioned.
In other words, the teaching machine has not only the vibration damping and fixing function in the left-right direction but also the vibration damping and fixing function in the up-down direction by the both-side fixing members 4. Meanwhile, through the matching of the spring and the clamping plate 42, a larger placing space is provided when the teaching machine is placed, and the storage is more convenient.
Locating component 5 is including installing on the door body 2 with a pair of compression spring 51 on the relative casing 1 inner wall of door body 2, fixed mounting fixed plate 52 on the compression spring 51 extrudees fixed plate 52 through compression spring 51, comes to further press from both sides tight fixedly to the teaching machine, avoids the teaching machine to rock back and forth in casing 1 and lead to the teaching machine to damage. In a further embodiment, the movement surface of the edge of the fixed plate 52 close to one side of the casing 1 is tangential to the end surface of the teaching machine.
Through the effect at compression spring 51 and fixed plate 52, when closing the door body, the edge of fixed plate 52 can reach the terminal surface of teaching machine, and the one side that forms fixed plate 52 is contradicted with the terminal surface of teaching machine and is connected, fixes and the damping to the front and back of teaching machine.
Therefore, the vibration reduction and fixation of the teaching machine in three dimensions of front and back, left and right, up and down and the like can be formed through the structure. Greatly improving the vibration damping effect. Further, when the teaching machine is loaded, since the left and right engaging plates 42 can be opened at a predetermined angle, there is no case where the loading is difficult. After the teaching machine is placed in the door body 2, the fixing plate 52 on the door body can rotate to the end face of the teaching machine, and a positioning and vibration damping structure is automatically formed. The above structure is very convenient for operation.
For the broadcast volume and the tone quality that improve the teaching machine, it has loudspeaker 3 to inlay on casing 1, install dustproof subassembly on loudspeaker 3, dustproof subassembly is including inlaying just inside dust screen 6 that holds the chamber that has on casing 1, dust screen 6 holds the intracavity and has placed waterproof cotton 7, effectively avoids water to cause the damage to the teaching machine in getting into casing 1 from loudspeaker 3, loudspeaker 3 is located on the adjacent 1 lateral wall of casing that does not install locating component 5 of fixed subassembly 4, come the external dust of separation to get into through dustproof subassembly and cause the teaching machine tone quality impaired.
It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the utility model. The utility model is not described in detail in order to avoid unnecessary repetition.
