The invention relates to the technical field of sports equipment, and discloses a lifting horizontal bar which comprises a supporting column, a lifting rod and a transverse rod, the other end of the lifting rod extends into the supporting column and is provided with a piston, a partition plate is arranged at the position 5 cm below the middle of an inner cavity of the supporting column and divides the inner cavity of the supporting column into two parts, and an upper cavity is formed above the partition plate; a lower cavity is arranged below the partition plate, a check valve is arranged in the partition plate, the lower end of the check valve is fixedly connected with a pipeline, the other end of the pipeline is two centimeters close to the bottom of the lower cavity, the lower cavity is filled with liquid, a backflow port is formed in one side of the check valve in the partition plate, and a pull pin is arranged below the backflow port. The transverse rod is pushed upwards, the transverse rod drives the lifting rod to move in the upper cavity, then liquid in the lower cavity is sucked into the upper cavity through the pipeline, the position of the transverse rod is fixed, then the pull pin is pulled, the liquid in the upper cavity flows back into the lower cavity from the backflow opening, and the transverse rod can descend.

    本发明涉及体育器材技术领域,且公开了一种升降单杠,包括支撑柱、升降杆、横杆,升降杆的另一端伸入支撑柱的内部并且设有活塞,支撑柱的内腔中部的下方五厘米处设有隔板,隔板将支撑柱的内腔一分为二,隔板的上方为上腔,隔板的下方为下腔,隔板的内部设有止回阀,止回阀的下端固定连接有管道,管道的另一端靠近下腔底部两厘米,下腔的内部填充有液体,隔板的内部止回阀的一侧开设有回流口,回流口的下方设有拉销。通过向上推动横杆,横杆带动升降杆在上腔内移动,继而通过管道将下腔的液体吸入上腔,横杆的位置得以固定,再通过拉动拉销,使上腔内的液体由回流口回流至下腔内,横杆就会下降。
