Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below by referring to the accompanying drawings and examples.
Example 1
The present invention provides a sports floor for preventing sports injuries, which, as shown in fig. 1, comprises a bottom layer 1 and a top layer, the top layer being placed on the bottom layer 1. The bottom layer 1 is an elastic material, and may not be an elastic material, and is not particularly limited herein. The material of the top layer is an elastic material. The material of the top layer is capable of deforming under impact. The top layer comprises elastic periodic units 2 which are periodically arranged, gaps are formed between every two adjacent elastic periodic units 2, and drainage holes 3 are formed, so that drainage is facilitated, and the influence of expansion and contraction effects is prevented. The elastic periodic units 2 are arranged in a rectangular period so as to form the through drain holes 3. Each elastic periodic unit 2 is square or rectangular in shape. The top of the elastic periodic unit 2 is provided with anti-skid lines, so that the anti-skid effect of the sports floor is improved. Elasticity periodic unit 2 is hollow structure, is equipped with isolator 4 in the elasticity periodic unit 2, and isolator 4 is along vertical direction. The spacer 4 is an elastic material. The material of the partition 4 may be the same as that of the elastic periodic unit 2 or may be different from that of the elastic periodic unit 2. As shown in fig. 1, the partition 4 is in the vertical direction. The partition 4 divides the interior of the elastic periodic unit 2 into a first chamber 5 and a second chamber 6. The partition 4 is provided with a through hole 7, and the through hole 7 penetrates through the first chamber 5 and the second chamber 6 to form a passage for gas to flow. The number of the through holes 7 is more than one. The size of the through hole 7 is more than 1 millimeter and less than 1 decimeter. Under the impact action, the gas flows in the through holes 7, and the gas flows at once but cannot flow too fast, so that the time of the impact action is prolonged.
When the sports floor is suddenly impacted, the top of the elastic periodic unit 2 is stressed, airflow is formed between the first chamber 5 and the second chamber 6, and the airflow delays the time for the interior of the elastic periodic unit 2 to reach the air pressure balance, namely, the impacting time is increased, so that the impact force is reduced, the safety of the sports floor is improved, and when an athlete suddenly falls down, the sports floor is not easily damaged.
Example 2
On the basis of embodiment 1, the volumes of the first chamber 5 and the second chamber 6 are not equal. That is, in fig. 1, the widths of the first chamber 5 and the second chamber 6 are different. Because the first chamber 5 and the second chamber 6 have different widths or different top areas, when the same impact is applied, the top parts of the first chamber 5 and the second chamber 6 are deformed differently, so that different pressures are generated in the first chamber 5 and the second chamber 6, more gas flows through the through holes 7, the impact action time is prolonged more, and the safety of the floor is improved.
Example 3
In example 2, the through-hole 7 has a rectangular shape, and the longitudinal direction of the rectangular shape is in the vertical direction. Thus, the through-hole 7 is not easily closed by pressure when an impact is applied. Although the size of the through hole 7 is reduced, the through hole is not completely closed, so that the impact action time is prolonged, and the safety of the floor is improved.
Example 4
On the basis of example 3, as shown in fig. 2, the thicknesses of the tops of the first chamber 5 and the second chamber 6 are different. Thus, when the same acting force is applied, the tops of the first chamber 5 and the second chamber 6 are deformed differently, so that more gas flows through the through holes 7, the impact action time is prolonged, and the safety of the floor is improved.
Example 5
In example 4, as shown in fig. 3, a gap 8 is provided between the partition 4 and the bottom of the first chamber 5 and the second chamber 6. That is, the partition 4 is suspended at the bottom of the hollow structure. Thus, upon impact, the partition 4 moves downward in fig. 3, and then the partition 4 contacts the bottom of the hollow structure, and then the airflow is formed in the through hole 7 due to the difference in pressure in the first chamber 5 and the second chamber 6. In the embodiment, the downward movement process of the isolation part 4 is added, so that the impact occurs for a longer time, and the stress time is prolonged, thereby reducing the impact acting force and improving the safety of the floor.
Example 6
In example 5, the thickness of the spacer 4 was gradually reduced from the top to the bottom. That is, upon impact, the thinner portion of the partition 4 first contacts the bottom of the hollow structure, and then the thicker portion of the partition 4 contacts the bottom of the hollow structure. Because the thinner part of the isolation part 4 is easier to deform and the thicker part of the isolation part 4 is less easy to deform, the deformation process is longer, namely the impact time is prolonged, the impact acting force is reduced, and the safety of the floor is improved.
Example 7
The height of the gap 8 was varied from example 6. That is, at the gap 8, the bottom surface of the partition 4 is not horizontal. The bottom surface of the partition 4 may be an inclined surface or a zigzag surface. Preferably, the bottom surface of the partition part 4 is an inclined surface, so that when the floor is impacted, the time for the bottom surface of the partition part 4 to contact the bottom of the hollow structure is different, and the time difference is provided, so that the air flow is formed not only in the left and right directions in fig. 3, but also in the front and back directions in fig. 3, more air participates in the flow, the impacting time is prolonged more, the impacting acting force is reduced more, and the safety of the floor is improved more.
Further, at least some of the plurality of through holes 7 are distributed in the height direction. That is, these through holes 7 cannot be horizontally arranged in a row. In this way, more gas is caused to flow in the first chamber 5 and the second chamber 6, the time for the gas to reach a steady state is prolonged more, the force of impact is reduced more, and the safety of the floor is improved.
Further, the size of the through-hole 7 is different. Under the action of pressure, some through holes 7 are closed, and some through holes 7 are not closed. Thus, the gas moves more in the first chamber 5, the second chamber 6 and between the first chamber 5 and the second chamber 6, the time for reaching the equilibrium state is longer, the impact force is reduced more, and the safety of the floor is improved.
Example 8
In addition to example 1, the spacer 4 is in the horizontal direction. The partition 4 divides the elastic periodic unit 2 into two chambers arranged in the vertical direction. The spacer 4 is an elastic material. A through hole 7 is arranged between the two chambers. The number of the through holes 7 is more than 1. When the pressure balance type air compressor is impacted, the upper chamber shrinks firstly, and air is pressed to flow through the through hole 7 and enter the lower chamber, and finally, the pressure balance state is achieved. In this embodiment, the deformation of cavity is many, has prolonged the operating time more, has reduced the striking effort, has improved the security on floor.
The above description is only a preferred embodiment of the present application and should not be taken as limiting the present application, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present application should be included in the protection scope of the present application.
