Description

Technical Field

[0001] The utility model relates to the technical field of plastic material testing, in particular to an elastic particle anti-aging testing bracket. Background Art

[0002] The sports industry has developed rapidly in our country and has become an important part of national fitness.

[0003] The construction of various synthetic material sports venues in my country has an increasing demand for elastic particles, such as elastic filling particles in the runway and anti-skid particles on the surface, elastic filling particles in artificial turf, etc. The use of these particles can increase the elasticity or anti-skid performance of the runway or artificial turf to reduce physical damage to the human body, and is an indispensable part of artificial synthetic sports materials. The particles become hard after a period of use, and some particles will become sticky, hardened, powdered, cracked, etc. after long-term exposure to natural climate. Unqualified elastic particles will have a certain negative impact on the overall sports performance when used as artificial grass surface fillers, and will have a certain negative impact on the overall sports performance when used as surface anti-skid materials. These problems restrict the healthy development of artificial synthetic sports materials. Therefore, GB / T 43564-2023, GB / T 43565-2023 and GB / T43566-2023 standards were issued in 2023, setting test methods and index requirements for the aging resistance of elastic particles, one of the raw materials for sports field paving materials. The aging test method involves illumination and spraying. When the elastic particles are placed in the aging test machine, if the spray mode is encountered, the elastic particles are small in size and can be easily washed away, thereby blocking the aging test machine. Long-term illumination can easily cause the elastic particles to harden and clump in the aging test machine, thereby damaging the aging test machine. It is also difficult to remove the elastic particles after the test to evaluate the aging resistance. Utility Model Content

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1 To Attachment Fig. 9 The technical solution of the elastic particle aging resistance test bracket provided by the utility model is described in detail.

[0028] like Figure 1 As shown, the elastic particle aging resistance test bracket includes a bracket body 1, and the bracket body 1 is provided with a lower shell 11, an upper shell 12 and a water seepage cell 13, and the material is stainless steel. The lower shell 11 is a rectangular parallelepiped structure closed by the side and the bottom and open at the top. The upper shell 12 is a rectangular parallelepiped structure enclosed by the side and the top and open at the bottom. The upper shell 12 is detachably arranged on the lower shell 11. Specifically, the horizontal plane of the upper shell 12 is slightly larger than the horizontal plane of the lower shell 11, and the upper shell 12 is sleeved on the lower shell 11. At least one water seepage cell placement port 121 is arranged on the top of the upper shell 12 for placing the water seepage cell 13.

[0029] The water seepage cell 13 is used to place elastic particles. The main structure of the water seepage cell 13 is a cylinder 131 surrounded by the bottom and the side. A support arm 132 is provided at the top of the cylinder 131. The width of the support arm 132 is greater than the size of the water seepage cell placement port 121. The function of the support arm 132 is to place the water seepage cell 13 on the water seepage cell placement port 121. A water seepage circular hole 133 is provided at the bottom of the cylinder 131. The diameter of the water seepage circular hole 133 is 0.5mm to 1.0mm, which can ensure that elastic particles larger than 0.5mm are not washed away by water. The number of water seepage cells 13 can be customized according to the amount and quantity of elastic particles. The multiple water seepage cells 13 provided in the bracket body 1 can be used to place elastic particles of different time periods, and different elastic particles are not easily confused, which improves the test efficiency and ensures the accuracy of the test results.

[0030] The side of the lower shell 11 is provided with leaking holes 111 to discharge the water that has infiltrated the elastic particles. The leaking holes 111 are higher than the bottom of the lower shell 11 and lower than the bottom of the cylinder 131 of the water seepage unit cell 13. The elastic particles are mixed with debris smaller than 0.5 mm or elastic particle debris and other debris that flows into the cavity of the lower shell 11 through the water seepage unit cell 13. Due to the high specific gravity of the debris, the debris has time to sink to the bottom of the inner cavity of the lower shell 11 in the lower shell 11. The water that has infiltrated the elastic particles can flow out through the leaking holes 111 for buffering. The debris remains in the internal space of the lower shell 11, preventing the debris from flowing out of the bracket body 1 and damaging the aging tester.

[0031] When in use, the lower shell 11 and the upper shell 12 are combined, and the water-permeable cell 13 is placed on the water-permeable cell placement port 121 of the upper shell 12. The elastic granular material is placed in the water-permeable cell 13, and the height of the elastic granular material filled is lower than the top of the water-permeable cell 13 to prevent the water from floating the elastic granular material and flowing out of the water-permeable cell 13 during the spraying process. The bracket body 1 is placed on the sample tray of the aging tester, and the aging tester is turned on for testing. Fig.10 As shown, the spray device sprays water to the elastic particles in the water seepage cells 13. After the test is completed, the elastic particles are taken out from the water seepage cells 13 and the aging resistance is evaluated. The elastic particle aging resistance test bracket provided in this embodiment can easily take out the elastic particles after the test, thereby improving the work efficiency of the experimenter. Finally, the lower shell 11, the upper shell 12 and the water seepage cells 13 can be rinsed. The water seepage elastic particle aging resistance test bracket can meet the comprehensive test of light, heat, water and other factors of the elastic particle material in the simulated natural environment in the aging test box.

[0032] As a preferred solution of the embodiment, the elastic particle aging resistance test bracket also includes a bottom support seat 2, and the bracket body 1 is arranged on the bottom support seat 2, and the material of the bottom support seat 2 is stainless steel. Specifically, the bottom support seat 2 includes a bottom water tank 21 and side walls 22 located on both sides of the length direction of the bottom water tank 21. The two sides of the bottom water tank 21 are inclined surfaces, so that the water that has infiltrated the elastic particles is introduced into the bottom water tank 21. As a preferred method, the upper surface of the bottom water tank 21 has a certain downward slope along the drainage direction, which is convenient for the water flow to be collected and transported along the drainage direction. More specifically, the slope ranges from 1% to 2%. The side wall 22 is used to limit the placement position of the bracket body 1. A support net 23 is arranged above the bottom water tank 21, and the bracket body 1 is placed on the support net 23. After the water that has infiltrated the elastic particles flows out of the bracket body 1, it flows into the bottom water tank 21 through the support net 23. Preferably, a filter net (not shown in the figure) is arranged at the end of the bottom water tank 21 to further filter debris and prevent debris from damaging the aging test machine.

[0033] The elastic particle aging resistance test bracket has the advantages of simple structure, convenient operation and wide application range. The bracket main body structure can be used alone, or multiple bracket main bodies can be placed on the bottom support seat to improve the test efficiency.

[0035] So far, the technical solution of the utility model has been described in conjunction with the specific embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the utility model is obviously not limited to these specific embodiments. Without departing from the principle of the utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the utility model.
