Further: described elevating mechanism comprises the first motor, ball-screw, ball screw nut, limited block and elevating lever, the first described motor is connected with the lower end of ball-screw, described limited block is arranged on the upper end of ball-screw, the lower end of described elevating lever is movably connected on ball-screw by ball screw nut, and the upper end of described elevating lever is connected to the bottom of back up pad.
Further again: between the first described motor and ball-screw, to be provided with torque force limiting device.
Further again: the position of the corresponding two piece of first cabinet door in bottom surface of the first described storeroom is provided with track, and two piece of first described cabinet door is flexibly connected in orbit by slide block.
After adopting said structure, the utility model regulates the height of projector automatically by elevating mechanism, thus plays the object being convenient to impart knowledge to students; And it also has the function of self-protection, the first motor is prevented to be subject to excessive torsion and to cause the damage of self structure.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of elevating mechanism.
Embodiment
The portable instruments used for education of one as shown in Figure 1, comprise body 1 and projector 2, the bottom of described body 1 is provided with roller 7, the front side of described body 1 offers the first storeroom, the outside of the first described storeroom is connected with two piece of first cabinet door 9, the right side opening of described body 1 is provided with the second storeroom, the outside of the second described storeroom is connected with the second cabinet door 6, the first pinned connection is passed through on body 1 in the lower end of described second cabinet door 6, the top of described body 1 offers groove, back up pad 4 is connected with in described groove, described projector 2 is arranged in back up pad 4, the 3rd cabinet door 3 is connected with outside described groove, the second pinned connection is passed through on body 1 in one end of described 3rd cabinet door 3, also elevating mechanism is provided with in described body 1, described elevating mechanism is connected to the bottom of back up pad 4.The position of the corresponding two piece of first cabinet door 9 in bottom surface of the first described storeroom is provided with track 8, and two piece of first described cabinet door 9 is movably connected on track 8 by slide block.When using portable instruments used for education, it is made to utilize roller to move by promoting body 1, thus assigned address is transported to instruments used for education, after portable instruments used for education arrive assigned address, open the 3rd cabinet door 3 and start elevating mechanism, make elevating mechanism, by back up pad 4, projector 2 is transported to specified altitude assignment, then start projector to impart knowledge to students, and operating personnel can also open the first cabinet door 9 and the second cabinet door 6, some teaching necessitys are put into the first storeroom and the second storeroom is deposited.The design regulates the height of projector automatically by elevating mechanism, thus plays the object being convenient to impart knowledge to students; And it also has the advantage that structure is simple, be easy to manufacture and practicality and high efficiency.
