Description
Technical field
The utility model relates to teaching equipment de-sign manufacturing technology field, is specially a kind of two-way main line amplifier accessory of remote teaching.
Background technology
The development of China's Modern Education Technology originates in 1920's, is referred to as audio-visual education programme. The magic lantern, the media such as film that use in audio-visual education programme activity at that time are used for teaching than original knowledge from hearsay and print media afterwards, its circulation way has been leaped major step, belong to the category of Modern Education Technology, but this is not also the Modern Education Technology in complete meaning, the just primary stage of Modern Education Technology development. Electronic instruction equipment is that modern education educates indispensable device concept with Modern Education Technology such as computer, projector, magic lantern, recording, video recording, broadcast, film, TV, computers, use modern education theory and technology, by the design to teaching process and resource, exploitation, application, management and evaluation, to realize the theory and practice of teaching modernization. But, remote teaching on existing market two-way main line amplifier accessory lacks and not only contributes to the spacing of spring but also contribute to the device of the damping of electrical element in equipment case, the two-way main line amplifier accessory of remote teaching also having lacks and contributes to supporting the device with conditioning equipment case position, the demand of reality can not be met.
Practical novel content
The purpose of this utility model is to provide a kind of two-way main line amplifier accessory of remote teaching, to solve in above-mentioned background technology the problem proposed.
For achieving the above object, the utility model provides following technical scheme: a kind of two-way main line amplifier accessory of remote teaching, comprise equipment case, case lid and stationary installation, the upper end of described equipment case and the lower end opposite position of case lid are hinged by two groups of stationary installations, the opposite position of edges at two ends up and down of described equipment case and case lid is installed with first end block and the 2nd end block respectively, the two ends of described equipment case are installed with interface, the upper surface of described case lid and the bottom surface of equipment case are equipped with cushion blocking, the spring that described cushion blocking comprises rubber pad and is fixed in rubber pad.
Preferably, described cushion blocking divides two row's symmetries to be located at the upper surface of case lid and the bottom surface of equipment, and the contained spring quantity of cushion blocking is between 3 10 groups.
Preferably, described interface is provided with four groups, is symmetrically distributed in the two ends, left and right of equipment case.
Preferably, when described equipment case covers mutually with case lid, the fixing mode of first end block and the 2nd end block is that screw and nut are fixed or blocked button and fix with card block.
Compared with prior art; the beneficial effects of the utility model are: the utility model device is provided with the electronic component that cushion blocking can protect two-way trunk amplifier equipment inside well; damping effect well can be played; structure is simple; it is convenient for carrying and transport, reduces electrical element and contact surface generation rigid collision.
