[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0020] With reference to Figures 1 to 3 , the utility model provides an embodiment: a spliced plastic track, including splicing plate 1, the outer top end inner wall of splicing plate 1 is fixedly connected with multiple fixed blocks 2, and fixed block 2 provides stable support point for contraction column one 3, ensures the normal work of subsequent structure. The bottom of multiple fixed blocks 2 is fixedly connected with contraction column one 3 respectively, when adjacent splicing plate 1 is spliced, contraction column one 3 can contract under the action of external force, and splicing operation is facilitated;When splicing is completed, contraction column one 3 can restore to the initial state again, provides certain thrust, makes splicing plate 1 be connected closely. The bottom of multiple contraction column one 3 is fixedly connected with connecting strip 4 respectively, and connecting strip 4 is tightly pulled together with two splicing plates 1 by the elastic deformation of itself and the tension of contraction column one 3, forms firm connection. The two sides of multiple connecting strip 4 are fixedly connected with limiting block 6 respectively, in the splicing process, limiting block 6 cooperates with the limiting slot on the inner wall of splicing plate 1, and connecting strip 4 is accurately inserted into the correct position, guarantees the precision and stability of splicing. The two sides top end of multiple connecting strip 4 is fixedly connected with contraction column two 7 respectively, and the outer portion of splicing plate 1 is fixedly connected with fixed assembly for limiting and fixing installation.
[0021] With reference to Figures 1 to 3The fixing assembly comprises a plurality of fixing strips 9, which mainly provide a stable mounting base for the subsequent fixing plates 10, guide strips 11 and other structures. The proximal sides of the plurality of fixing strips 9 are fixedly connected to the outer bottom end of the splicing plate 1. The fixing strips 9 are mounted on the outer bottom end of the splicing plate 1 without affecting the flatness of the upper surface of the splicing plate 1, thereby ensuring the comfort and safety of the athletes when they exercise on the track. The distal sides of the plurality of fixing strips 9 are fixedly connected with the fixing plates 10. The presence of the fixing plates 10 increases the connection area between the splicing plates 1 and improves the stability of the connection.

The distal sides of the plurality of fixing plates 10 are fixedly connected with limiting plates 12. When the adjacent splicing plates 1 are completed, the limiting plates 12 abut against each other to limit the lateral displacement of the splicing plates 1.
[0022] Referring to Figures 1 to 3 The outer part of each of the plurality of contraction columns two 7 is sleeved with a spring two 8. When the external force disappears, the spring two 8 releases the elastic potential energy, pushes the contraction column two 7 to reset, and in turn drives the connecting strip 4 to return to the initial position. The outer part of each of the plurality of contraction columns one 3 is sleeved with a spring one 5. When the splicing is completed, the spring one 5 releases energy to generate a pushing force to pull the contraction column one 3 to stretch outward.

When the contraction column two 7 is moved downward under the action of external force, the spring two 8 is compressed, and the top fixed point thereof provides a reverse pulling force to ensure that the spring two 8 can be uniformly stressed and store elastic potential energy. The outer part of each of the plurality of limiting blocks 6 is slidingly connected to the inner wall of the splicing plate 1. The sliding of the limiting block 6 in the limiting slot can limit the lateral movement of the connecting strip 4 to prevent the connecting strip 4 from being deviated or misaligned due to external force, thereby ensuring the stability of the splicing part. The bottom end of each of the plurality of springs one 5 is fixedly connected to the top end of each of the plurality of connecting strips 4. When the connecting strip 4 is slightly displaced under the action of external force, the spring one 5 will automatically adjust the pulling force according to the displacement to timely pull the connecting strip 4 back to the original position, thereby ensuring that the splicing part is always in a stable state.
