Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: the utility model provides an ideological and political theory teaching xuan podium with adjustable, includes xuan podium body 1, the bottom fixedly connected with underframe 2 of xuan podium body 1, the bottom fixedly connected with gyro wheel 3 of underframe 2.

The inner wall of underframe 2 rotates through bearing and pivot to be connected with two gears 4, and the side meshing of gear 4 has pinion rack 5, is equipped with in underframe 2 to be used for carrying out the guiding mechanism injectd to 5 movement tracks of pinion rack, and the bottom fixedly connected with and the ground contact of pinion rack 5 for to explaining that platform body 1 carries out fixed locating

plate

6, 2 internal rotation connections of underframe have and are used for driving gear 4 pivoted actuating mechanism.

Guiding mechanism includes guide bar 7 of fixed connection on 2 inner walls of underframe, and sliding sleeve is equipped with removal cover 8 on guide bar 7, removes cover 8 and pinion rack 5 fixed connection.

When the height of xuan dai body 1 is adjusted to needs, rotate actuating mechanism, drive gear 4 and rotate, gear 4 and the meshing of pinion rack 5, make pinion rack 5 can drive locating plate 6 and reciprocate, guide bar 7 and removal cover 8 have injectd the movement track of pinion rack 5, make more steady smooth and easy that pinion rack 5 reciprocated, can drive locating plate 6 and rise or descend, thereby can adjust the height of xuan dai body 1, the crowd of the different heights of adaptation of being convenient for uses.
