The beneficial effects of the utility model：

1st, the multimedia lectern of the utility model carries seat, the shape being connected as one using multimedia lectern and seat Formula when needing using seat, need to will only open the cabinet door of lectern cabinet, seat horizontal is rotated taking-up using rotation link arm Use, and when not needing to using seat, only seat horizontal need to be rotated into suitable position using rotation link arm, Just seat storage is hidden in the second cavity of cabinet while closing cabinet door so that multimedia lectern is as common lectern It uses, the space for placing lectern place will not be in addition occupied, while also improve the space availability ratio of lectern, convenient for transporting in batches It is defeated, it is cost-effective.

2nd, the multimedia lectern of the utility model carries seat in the abutment sleeve of support element and the axle sleeve of rotation link arm Junction is provided with elastic buffering mechanism so that when user is not sitting on bench, the spring of elastic buffering mechanism can incite somebody to action Bench jack-up is placed in vacant state, so that the slidingtype bench support feet of seat conveniently passes through rotation apart from ground one end distance Seat is adjusted during the merging of switch cabinet door, taking-up or use；When user is sitting on bench, bench can be because of user's weight The effect of power generates the lower pressure for overcoming elastic buffering mechanism so that the abutment sleeve of support element and the axle sleeve of rotation link arm are sent out Relative displacement above and below raw so that prevented with forming firm support to bench on the slidingtype bench support feet contact ground of seat Only bench generates excessive lower pressure and generates damage to cabinet door in use.

3rd, the multimedia lectern of the utility model carries seat and is provided with number on the madial wall of the axle sleeve of rotation link arm A plunger body, the corresponding position of abutment sleeve are provided with the limiting slot worked in coordination with plunger body, utilize plunger body and limiting slot Snap fit is realized abutment sleeve and axle sleeve limiting in use state, in addition, the bottom end setting of the abutment sleeve in support element There is slidingtype bench support feet, one side slidingtype bench support feet increases the contact area on seat and ground, and raising is known clearly The stability of seat when in use；Another aspect slidingtype bench support feet is not when bench sits people, slidingtype bench support feet The first spring the sub-fraction of sphere can be ejected to the sphere sliding eye of hollow shell bottom by concave ball shape block, sphere at this time It can be contacted with ground surface, at this time can be with Convenient chair under the effect of external force, and the fixing axle in cabinet door will not be generated and be made an uproar The arbitrary slip of sound, so as to which seat easily is adjusted to user desired position；When user is sitting on bench again When, the first spring can be by the gravity compressed of people so that sphere is contacted by ground and supported completely into hollow shell by ground completely In hollow cavity, bench cannot occur arbitrarily to slide at this time, user-friendly；It only need to slightly exert oneself when without using seat Lift bench so that plunger body and limiting slot are detached from just using the restoring force of elastic buffering mechanism by abutment sleeve and axle sleeve It is restored to without using state, to treat that storage is hidden, clever structure is easy to operate, easy to use.

4th, the multimedia lectern of the utility model carries seat, as long as closing cabinet door, so that it may by seat opening via cabinet It stores and is hidden in the second cavity of cabinet at mouthful, it is easy to operate, it is easy to use；And since seat is when not in use without long-term It is exposed on the one hand to avoid the unexpected of seat outside lectern and lose, it on the other hand avoids cleaning again or arranges to clean to say Seat is damaged during table, extends the service life of seat.

5th, the dais of the utility model by lifting gear can be up and down be installed on above cabinet, can be according to different religions Adaptively the height of table surface is said in adjustment for the height of teacher, avoid caused due to lectern height and teacher's height mismatch teaching or Tired sense when person gives a lecture so as to bring the mood of light pleasure to teacher, brings good teaching speech effect；Dais and cabinet Pass through the mutual cooperation of electric pushrod, dais mounting base, sliding block and supporting skid rail between body so that say the adjustable height of table surface It is more accurate steady, the failure rate said in table surface lifting process is reduced, so as to save the maintenance cost in later stage；This practicality The novel integrated system that various electronic devices are formed to complete set by control circuit, it is convenient to be completed by network long-range Operation and control and unified management, not only increase the efficiency of management, management cost are also greatly saved, suitable for being widely used to promote.

6th, the utility model is provided with reversible pallet device, and computer display screen can be mounted on display screen pallet, The front and rear overturning of pallet is driven by electric pushrod expanding-contracting action, to realize that the display device being installed on pallet carries out angle tune It is whole, realize that display screen is more accurately maintained at best flip angle, it is small, it is simple in structure, it is easy to operate, difference can be met The use demand of teacher；And multigroup air hole is provided on the display screen pallet of reversible pallet device, display screen is facilitated to radiate, Effectively extend the service life of display screen.
