[0002] Dance is a performing art that uses the body to perform various graceful or difficult movements, usually accompanied by music, and uses rhythmic movements as the main means of expression. The performance of beautiful dance on stage usually requires dancers to undergo hard training off stage. During training, it is usually necessary to lay dance mats on the training ground to help with training, which can help dancers reduce the impact on their joints and improve their dance skills and flexibility. However, existing dance mats usually need to be manually rolled up after use, which is very inconvenient. Moreover, during training, the dance mats are easily contaminated with dust, and the dance mats need to be cleaned before being rolled up, which is very troublesome. Utility Model Content

[0003] The utility model aims to provide a portable dance mat structure for dance training, which can be convenient for rolling up the dance mat and convenient for cleaning dust on the dance mat.

[0006] One end of the outer side of the winding shaft is rotatably connected to a first ratchet, an end of the winding shaft close to the first ratchet is provided with a first limiting groove, a first clamping block slidably connected to the first ratchet is slidably connected inside the first limiting groove, a first spring is provided between the first clamping block and the first limiting groove, a first gear is provided on the outer side of the first ratchet, a second gear meshing with the first gear is provided at one end of the first cotton brush roller close to the first gear, and a third gear meshing with the second cotton brush roller is provided at one end of the second cotton brush roller close to the second gear;

[0007] A second shell is provided at one end of the first shell, and a third shell is provided at the other end of the shell, a mainspring is provided inside the second shell, one end of the mainspring is connected to the winding shaft, and the other end of the mainspring is connected to the second shell, one end of the winding shaft extends into the third shell where a second ratchet is provided, a second limiting groove is provided on the outside of the third shell, a second clamping block slidably connected to the second ratchet is slidably connected to the inside of the second limiting groove, and a pull rod slidably connected to the second limiting groove is provided at one end of the second clamping block away from the second ratchet.

[0008] By adopting the above technical solution, when it is necessary to lay a dance mat on the training ground, the foam pad is pulled from the storage opening of the first shell, and the foam pad drives the winding shaft to rotate, and the winding shaft drives the first clamping block to rotate along with it. During the rotation of the first clamping block, it rotates relative to the first ratchet wheel. At the same time, the first clamping block slides in the first limiting groove to compress the first spring. The elastic force generated by the first spring can drive the first clamping block to reset. The rotation of the winding shaft drives the spring in the second shell to contract, and the winding shaft drives the second ratchet wheel in the third shell to rotate. When the second ratchet wheel rotates, it can drive the second clamping block to slide in the first limiting groove, and the second clamping block drives the support rod to slide relative to the second limiting groove. When the foam pad is laid, the second clamping block The block clamps the second ratchet to prevent the spring elastic force from driving the winding rotation; when the foam pad needs to be wound up, the pull rod is pulled, and the pull rod drives the second clamping block to slide in the second limiting groove, so that the second clamping block does not jam the second ratchet, and then under the action of the spring elastic force, the winding shaft is driven to rotate to wind up the foam pad, the rotation of the winding shaft drives the first clamping block to rotate, the first clamping block clamps the first ratchet, driving the first ratchet to rotate, the first ratchet drives the first gear to rotate, the first gear drives the second gear to rotate, the second gear drives the first cotton brush roller to rotate, the second gear drives the third gear to rotate, the third gear drives the second cotton brush roller to rotate, the first cotton brush roller rotates and the second cotton brush roller rotates to clean the dust on the foam pad.

[0009] The utility model is further configured as follows: a second spring is arranged on the outer side of the pull rod between the second clamping block and the second limiting groove.

[0010] The utility model is further configured as follows: a handle is provided at one end of the pull rod away from the second clamping block.

[0011] The utility model is further configured as follows: a limiting rod is provided at one end of the foam pad away from the winding shaft, and the length of the limiting rod is greater than the length of the storage opening.

[0012] The utility model is further configured as follows: a plurality of suction cups are arranged at equal intervals at the lower end of the first shell.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] First, the dance mat can be rolled up conveniently. When in use, the foam pad is pulled out from the storage opening by pulling the limit rod, which drives the winding shaft to rotate. The winding shaft drives the spring to compress and drives the second ratchet to rotate at the same time. Then the second clamping block clamps the second ratchet to prevent it from rotating. After use, the pull rod is pulled to drive the second clamping block to slide. The second clamping block does not clamp the second ratchet. Under the action of the spring elastic force, the winding shaft is driven to rotate, and the winding shaft rolls up the foam pad.

[0015] Secondly, it is convenient to clean the dust on the foam pad. The mainspring drives the winding shaft to rotate under the action of elastic force to reel in the foam pad. During the reeling process, the winding shaft drives the first block to rotate, thereby driving the first ratchet to rotate, the first ratchet drives the first gear to rotate, the first gear drives the second gear to rotate, and the second gear drives the third gear to rotate, thereby driving the first cotton brush roller and the second cotton brush roller to rotate to clean the dust on the foam pad.
