Preferably, four corners of the backing plate are provided with a bracket, and the bracket includes a support, a telescopic rod, a universal joint and a connecting rod from bottom to top, wherein the connecting rod is connected to the lower surface of the backing board, and the telescopic rod It is composed of an inner rod and an outer pipe connected by threads.

Preferably, the rope is provided with a fixed buckle on one movable end.

Preferably, the rope is provided with a fixed ball at the end of the movable end, and the diameter of the fixed ball is larger than the diameter of the through hole.

Preferably, a rubber pad is provided above the backing plate.

The beneficial effect is that: the seat cushion of the sit-up device is composed of several fixing plates, so that the seat cushion can be folded and is easy to carry; at the same time, the fixing plates are connected by ropes, so that the fixing plates can be firmly connected together. Because the backing plate is composed of a fixed plate, the backing plate can fix the foot support, preventing the foot support from moving upward due to excessive force. In addition, the rope can increase the range of motion of the fixed plate, which is convenient for folding or rolling up, and also avoids the loss of the fixed plate. The shaping rods are clamped in the grooves on both sides of the backing plate to adjust the overall shape of the backing plate, so that the backing plate changes shape and is more ergonomic. There are also brackets on the four corners of the backing board, which can adjust the height and position of the backing board to adapt to users of different body shapes. At the same time, after installing shaping bars on both sides of the backing board, the backing board can also be made more stable. In addition, there is a fixed ball at the end of the rope, which can prevent the fixed plate from slipping off the rope. The fixed buckle on the rope can fasten the rope to prevent the fixed plate from moving. The rubber pad on the backing plate can make the sit-up device more comfortable in use.

detailed description

Preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

Fig. 1 and Fig. 2 show the specific embodiment of a kind of sit-up device of the present utility model: a kind of sit-up device comprises backing board 1 and foot support 2, and wherein said backing board 1 comprises several fixed boards 3, each Both ends of the fixed plate 3 are provided with through holes, and a rope 4 is provided in the through hole to pass through. One end of the rope 4 is fixed on the fixed plate 3 at the end, and the other end of the rope 4 is movable. At one end, the foot support 2 includes an elastic cord 5 and a cross bar 6 , and the elastic cord 5 connects the backing plate 1 and the cross bar 6 .

It is worth noting that grooves 7 are provided on the side surfaces of both sides of the backing plate 1, and elastic blocks are arranged on the inner walls of both sides of the groove 7, and shaping rods 8 are arranged between the elastic blocks in the groove 7, and the shaping rods 8 is curved. The four corners of the backing plate 1 are provided with a bracket 9, the bracket 9 includes a support 10, a telescopic rod 11, a universal joint 12 and a connecting rod 13 from bottom to top, wherein the connecting rod 13 is connected to the bottom of the backing plate 1. On the lower surface, the telescopic rod 11 is composed of an inner rod 14 and an outer tube 15 which are threaded. The rope 4 is provided with a fixed buckle 16 on one movable end. The end of the movable end of the rope 4 is provided with a fixed ball 17, and the diameter of the fixed ball 17 is larger than the diameter of the through hole. A rubber pad 18 is arranged above the backing plate 1 .

Before doing sit-ups, the device can be taken out and unfolded, and the fixed plates 3 are tiled in sequence. Then the rope 4 is knotted or the fixing plate 3 is fixed and tightened by using the fixing buckle 16 . Finally, the rubber pad 18 is spread on the backing plate 1 . During the sit-up exercise, the foot is fixed with the foot support 2, and then the sit-up can be done. At the same time, the shape of the backing plate 1 can also be changed by using the shaping rod 8, which is more ergonomic. At this time, the support 9 is used to ensure the balance and stability of the backing plate 1.

Based on the above, the seat cushion of the sit-up device is composed of several fixed plates 3, so that the seat cushion can be packed up and is easy to carry. At the same time, the fixed plates 3 are connected by ropes 4, so that the fixed plates 3 can be firmly connected Together.
