The utility model can accommodate the matching petri dish of multiple types, and the operation is convenient and reliable.

A fabric body comprises a plurality of basic weave units, each basic weave unit is a plain weave formed by interweaving warp yarns and weft yarns, the warp yarns comprise first warp yarns and second warp yarns which are alternately arranged, and deep and shallow vertical stripes which are alternately arranged are formed. The warp density of the warp yarns of the deep vertical stripes is larger than that of the light vertical stripes, the width of the light vertical stripes is larger than that of the deep vertical stripes, the fabric body has a concave-convex feeling, the color of the fabric body is layered after dyeing, the fabric body has a bubble hand feeling, and the warp yarns are 15D / 6F semi-dull chinlon FDY; the weft yarns comprise yarns A and yarns B, and the yarns A 21 are 15D / 6F semi-dull chinlon FDY; the A yarns are 30D / 12F semi-gloss chinlon FDY, the B yarns are 30D / 12F semi-gloss chinlon FDY, seven wefts of the fabric main body form a cycle, six A yarns and one B yarn which are sequentially arranged are arranged in one weft cycle, the B yarns correspondingly form transverse stripes, and plaid patterns are formed between the transverse stripes and the deep and shallow vertical stripes. And more and better selection requirements of consumers can be met.

The utility model discloses a walking aid suitable for muscle strength training of old people. The walking aid comprises a support, armrests and foot training rings. The handrails are arranged on the two sides of the support and slidably connected with the support, locking knobs matched with the handrails are arranged on the support, a connecting rod is arranged between the handrails, a supporting frame is arranged on the connecting rod, placing rings are arranged on the two sides of the supporting frame, a timer is arranged in the middle of the connecting rod, and a connecting ring is arranged at the position, located on the supporting frame, of the connecting rod. The foot training ring is connected with the connecting ring through an elastic belt; and the grip ball is placed on the placing ring. The handrails located on the two sides of the supporting frame serve as main structures and are matched with the foot training rings and the grip balls, integration of multiple training modes is achieved, the grip balls can be taken and placed by different people through the placing rings arranged on the supporting frame, the exercise time can be controlled through the timer, the overall structure is simple, use is convenient, and practicability is high. The selection requirements of different exercise modes can be met, and the muscle strength exercise effect can be effectively achieved.
