[0002] Dance is a performing art that uses the body to perform various graceful or difficult movements. It takes ten years of hard work to perform one minute on stage. Long-term training is required to complete these difficult movements. During the training, dancers need to stretch their ligaments and have good flexibility to complete more difficult movements. The barre is used during the ligament stretching training. The barre is a tool for leg stretching.

[0003] However, the existing dance bar structure has very single functions, and it is difficult to perform accurate leg stretching training for students of different heights. Therefore, we propose a sports dance training teaching aid to solve the above-mentioned problems. Utility Model Content

[0008] A height adjustment mechanism, the height adjustment mechanism is connected to the two support tubes respectively, a support beam is installed on the top of the height adjustment mechanism, a support sleeve is fixed on the support beam, and the support sleeve is used to support the legs of the trainees;

[0009] A leg-pressing mechanism is installed on the support beam and is used to apply pressure to the legs of the trainees.

[0010] In a possible design, the height adjustment mechanism includes two nuts rotatably connected to the top ends of the two support tubes respectively, a screw rod is threadedly connected through the nut, and the top ends of the two screw rods are fixedly connected to the bottom of the support beam.

[0011] In a possible design, a synchronous wheel is fixedly sleeved on the nut, and the two synchronous wheels are connected to the same synchronous belt for transmission, a positioning assembly is installed on the inner side of the synchronous belt, and a same limit plate is fixedly installed on the side where the two support tubes are close to each other, and a plurality of clamping holes are evenly spaced on the limit plate, and the positioning assemblies are movably clamped with the plurality of clamping holes respectively.

[0013] In a possible design, a compression spring located above the moving ring is sleeved on the mounting rod, and the top and bottom ends of the compression spring are fixedly connected to the top of the mounting rod and the top of the moving ring respectively.

[0014] In a possible design, the leg-pressing mechanism includes two connecting rings symmetrically rotatably connected to a support beam, a pressing arm is fixedly installed on the top of the connecting ring, and the same pressing rod is fixedly installed on the top of the side where the two pressing arms are close to each other, and a pressing sleeve is fixed on the pressing rod.
