The invention discloses a student desk, including a desk board, a table leg is supported on the lower surface of the table board, a lifting table board is covered with a lifting table board, a pair of front lifting rods and a pair of rear lifting rods are supported on the lifting table board, a pair of front lifting rods are driven by a front driving positioning device and a pair of rear lifting rods are driven and fixed together. The front lifting rod and the upper end of the rear lifting rod are articulated with the lifting table plate. The front articulated part is fixed on the slide plate, and the lower surface of the lifting table plate is provided with a sliding groove, the slide block is in the sliding groove, and a block part is arranged on the sliding groove to prevent the slide block from coming out of the sliding groove. The student's desk has a lifting table board. When the student is tired of sitting, he can change the lifting table board into standing position. In order to facilitate reading, he can adjust the height of the front lifting bar and the rear lifting bar so that the lifting table board can be tilted forward, so that the student can stand at a distance and can see. The learning videos and books on the desk are easy to operate and read generally.
【技术实现步骤摘要】
学生书桌
本专利技术涉及一种学生书桌。
技术介绍
传统书桌一般包括桌板和支承桌板的四条桌腿,学生学习时只能采用坐姿。但是,坐姿学习时间较长后容易导致疲劳,以及影响健康。
技术实现思路
本专利技术所要解决的技术问题是提供一种学生书桌,该学生书桌既方便坐姿学习又方便站姿学习,并且能够根据需要调整桌板向前倾斜的角度。为此,本专利技术提供的学生书桌,包括桌板,桌板下表面支承有桌腿,所述桌板上方覆盖有升降桌板,升降桌板支承有一对前升降杆和一对后升降杆,一对前升降杆共同受前驱动定位装置驱动而升降,一对后升降杆共同受后驱动定位装置驱动而升降,所述前升降杆和后升降杆上端均与升降桌板铰接,所述前铰接部通过固定于滑块上,所述升降桌板下表面带有滑槽,滑块处于滑槽中,滑槽上设置有挡位部阻挡滑块脱出滑槽。本专利技术的技术效果:该学生书桌具有可升降桌板,当学生坐姿学习疲劳时可以将升降桌板上升转换为站姿学习,为了方便站姿看书还可以通过调整前升降杆和后升降杆使两者高度不一,进而使升降桌板能够向前倾斜,使学生可以站在远处也能够看到书桌上播放的学习视频和书籍等,方便一般操作一般看书。上述多方位的学习状态 ...
