[0005] Technical solution of the utility model: A foldable chorus stand, whose structure includes three layers of pedals, side brackets, pulleys and telescopic guardrails. The bottom parts of the three layers of pedals are respectively fixed with a top bracket, a middle bracket and a bottom bracket. When opened, the heights of the three layers of pedals are spaced and parallel to each other from high to low. The rear parts on both sides of the top bracket, the middle bracket and the bottom bracket are respectively rotationally connected to the top, middle and lower parts of the two side brackets. A number of cross bars are connected between the two side brackets. Pulleys are respectively arranged at both ends of the bottom of the side brackets. A telescopic guardrail is also connected between the tops of the two side brackets. Middle lower support rods extending downward and middle upper support rods extending upward are respectively vertically fixed at the front and rear parts on both sides of the middle bracket. Bottom upper brackets extending upward are respectively vertically fixed at the rear parts on both sides of the bottom bracket. When opened, the middle upper support rods support at the bottom of the top bracket, and the middle lower support rods and the bottom upper brackets support each other. Diagonal connecting rods are respectively rotationally connected to both sides between the top bracket and the middle bracket and between the middle bracket and the bottom bracket. When in use, the chorus stand in the folded state is moved to the required position through the pulleys. First, the telescopic guardrail is removed, and then the three layers of pedals are turned outwards from bottom to top in sequence. The middle lower support rods and the bottom upper brackets support each other, and the middle upper support rods support at the bottom of the top bracket to complete the opening of the chorus stand. When folding, the three layers of pedals are folded upwards from top to bottom in sequence, and the telescopic guardrail is rotated downwards and sleeved outside the three layers of pedals to complete the folding of the chorus stand.

[0006] Preferably, it further includes detachable and adjustable legs, which extend downward and are detachably arranged at the bottom of the pedal at the front part inside the bottom bracket. When opened, the detachable and adjustable legs support on the ground.

[0007] Preferably, the detachable and adjustable support legs are detachably connected to the hoop seats at the bottoms of the corresponding pedals, and the bottoms of the corresponding pedals are provided with cradles that match the shapes of the detachable and adjustable support legs. When in need of use, the detachable and adjustable support legs can be removed from the cradles and fixed in the hoop seats.

[0008] Preferably, the telescopic guardrail includes an outer sleeve fixed to the tops of the side brackets on both sides and an inner guardrail tube whose lower part is sleeved inside the two ends of the outer sleeve, and the upper parts of the inner guardrail tubes on both sides are sleeved with each other. When in use, it can be pulled outwards or contracted inwards to switch different guardrail widths.

[0009] Advantages of the present utility model: The structure is reasonably designed. When folded, it not only occupies a small area, but also fixes the folded pedals through the telescopic guardrail, which can prevent tipping and reduce potential safety hazards. It is convenient to open, has structural stability, and can effectively ensure the use effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present utility model will be further described in detail below in conjunction with the embodiments and specific implementation manners.

[0016] As Figures 1 - 4As shown in the figure, a foldable chorus platform, the structure of which includes three layers of pedals 1, side brackets 2, pulleys 4, telescopic guardrails 5 and detachable and adjustable legs 13. The bottom of the three layers of pedals 1 are respectively fixed with a top bracket 6, a middle bracket 7 and a bottom bracket 10. When opened, the heights of the three layers of pedals 1 are spaced from high to low and parallel to each other. The rear parts of both sides of the top bracket 6, the middle bracket 7 and the bottom bracket 10 are respectively rotatably connected to the top, middle and lower parts of the two side brackets 2 on both sides. A number of cross struts 3 are connected between the two side brackets 2. Pulleys 4 are respectively arranged at both ends of the bottom of the side brackets 2. A telescopic guardrail 5 is also connected between the tops of the two side brackets 2. The front and rear parts of both sides of the middle bracket 7 are respectively vertically fixed with a middle lower strut 9 extending downward and a middle upper strut 8 extending upward. The rear parts of both sides of the bottom bracket 10 are respectively vertically fixed with a bottom upper bracket 11 extending upward. A detachable and adjustable leg 13 extending downward is detachably arranged at the bottom of the pedal 1 at the front part inside the bottom bracket 10.
