The utility model discloses a rubber floor mat capable of being spliced, and relates to the technical field of rubber floor mats, the rubber floor mat comprises two rubber floor mats, the bottom surfaces of the two rubber floor mats are fixedly connected with first non-slip mats, and the top surfaces of the two rubber floor mats are fixedly connected with second non-slip mats; through the cooperation of the first non-slip mat and the second non-slip mat, the rubber floor mat does not move and slip during use, the safety is improved, the non-slip function is achieved, through the cooperation of the trapezoidal clamping grooves in the rubber floor mat and the connecting blocks, splicing of the rubber floor mat is facilitated, the splicing efficiency is improved, the splicing function is achieved, and the service life of the rubber floor mat is prolonged. And then through cooperation of a blocking piece, a first spring, a guide rod and a second spring, pressure buffering is facilitated, the comfort is improved, the double-buffering function is achieved, and finally the problems that when the spliced rubber floor mat is used, slipping and falling apart are likely to happen, and the comfort is poor due to the fact that the spliced rubber floor mat is too hard and free of buffering are solved.
