Abstract
The utility model discloses an elasticity surface course remnant deformation tester, include: a main frame, it includes an at least crossbeam, base and two spinal branch daggers and locates three guide bars on the crossbeam, be equipped with a round hole on the base, a bearing dish, it is fixed through lock nut on three guide bars, a pressure head, it is located the center of round hole, not with base contact, just open at the pressure head middle part has the guiding hole, and one is located the centre the guide bar inserts in the guiding hole, guide bar in the middle of being located not with the guiding hole contact, the pressure head place in in the round hole, a weight, its place in on the bearing dish. The utility model discloses an elasticity surface course remnant deformation tester has advantages such as easy operation, simple structure, low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of elastic surface layer residual deformation tester.
Background technology
Athletic floor has the history of more than 100 year in Europe, because its superior performance and the protection to environment, become ground preferred material in a lot of country.Athletic floor since 20th century, the nineties entered China, pandemic throughout the country, and be widely used in various sports center, as match and training sites such as basketball, table tennis, shuttlecocks, the playground etc. of school, amusement park.
Athletic floor is more and more extensive in the application of China, but at present at home, the detectability for athletic floor performance is not comprehensive, and the residual deformation performance for athletic floor does not also have associated assay devices.And external checkout equipment is expensive, complicated operation.
Utility model content
Because prior art exists the problems referred to above, the utility model proposes a kind of elastic surface layer residual deformation tester, it effectively can solve the problems referred to above of prior art.
The utility model solves the problem by the following technical programs:
A kind of elastic surface layer residual deformation tester, comprising: a main frame, they three guide poles comprising at least one crossbeam, base and two support columns and be located on described crossbeam, described base is provided with a circular hole; One load-bearing plate, it is fixed on described three guide poles by set nut; One pressure head, it is positioned at the center of described circular hole, not with described base contacts, and have pilot hole in the middle part of described pressure head, one is positioned at middle described guide pole inserts described pilot hole, described in be positioned at middle guide pole and do not contact with described pilot hole, described pressure head is positioned in described circular hole; One counterweight, it is placed on described load-bearing plate.
The diameter of described circular hole is 300mm.
The quality of described pressure head is 306g, and this pressure head diameter is 25mm.
The gross mass of described counterweight and described load-bearing plate is 51kg.
Elastic surface layer residual deformation tester of the present utility model, has the advantages such as simple to operate, structure is simple, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is an example structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with embodiment, describe the utility model in detail.
Shown in Figure 1, Fig. 1 is an example structure schematic diagram of the present utility model.
The elasticity aspect residual deformation tester of the present embodiment, comprising: a main frame 1, they three guide poles 5 comprising at least one crossbeam 11, base 12 and two support columns 13 and be located on described crossbeam, and described base 12 is provided with a circular hole; One load-bearing plate 4, it is fixed on described three guide poles by set nut 6; One pressure head 2, it is positioned at the center of described circular hole, not with described base contacts, and have pilot hole in the middle part of described pressure head, one is positioned at middle described guide pole 51 inserts described pilot hole, the described guide pole being positioned at centre does not contact with described pilot hole, and described pressure head is positioned in described circular hole; One counterweight 3, it is placed on described load-bearing plate 4.
Wherein, the diameter of described circular hole is 300mm, and pressure head is placed in described circular hole, and pressure head does not contact with described circular hole, plays the effect not affecting pressure head while of keeping pressure head stable.
The quality of described pressure head is 306g, and this pressure head diameter is 25mm.The edge, lower surface of described pressure head 3 has done the chamfered that radius is 0.5mm.Avoid and reduce the infringement of acute angle to athletic floor.
The gross mass of described counterweight and described load-bearing plate is 51kg.
Elastic surface layer residual deformation tester of the present utility model, its principle of work is: whole device is positioned on athletic floor, put down pressure head 2 and load-bearing plate 4 successively, again counterweight 3 is placed on load-bearing plate 4, after 5 hours, counterweight 3 is removed, lifting load-bearing plate 4 is also locked by it, then removes pressure head 2, measures depth of cup after 5 minutes and record.There is the advantages such as simple to operate, structure is simple, low cost of manufacture.
Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
