Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, the above terms should not be construed as limiting the present invention.
As shown in fig. 1 and 2, the composite arched treadmill plate comprises a wear-resistant layer 1, a buffer layer 2 and a bearing layer 3, wherein the wear-resistant layer 1 and the bearing layer 3 are both made of MDF plates or other materials, the thickness of the bearing layer 3 is more than 2 times of that of the wear-resistant layer 1, and the buffer layer 2 is made of TPU or other materials such as E-TPU or EVA.
Preferably, in order to guarantee the good buffering shock attenuation effect of race board and wear-resisting effect and bearing effect, wearing layer 1, buffer layer 2 and the thickness of bearing layer 3 increase gradually in proper order.
In the embodiment, the preferable thickness range of the wear-resistant layer 1 is 3-10 mm, such as 4mm, 5mm, 6mm, etc.; the preferable thickness range of the bearing layer 3 is 8-25 mm, such as 8mm, 9mm, 20mm, 24mm and the like, and is always more than twice of the thickness of the wear-resistant layer 1, and if the thickness of the wear-resistant layer 1 is 6mm, the thickness of the bearing layer 3 is at least 12 mm; the preferred thickness of buffer layer 2 is between 5 ~ 30mm, like 6mm, 8mm, 25mm and 30mm etc. all can, keep thickness all the time and be greater than wearing layer 1, can exceed the thickness of bearing layer 3, and the area of buffer layer 2 is less than wearing layer 1 and bearing layer 3's area moreover, and if the preferred length of buffer layer 2 is 200 ~ 500mm, the width is 300 ~ 800mm, and theoretically wearing layer 1 area is the biggest. Compared with the prior art, this application only needs adjust the thickness of buffer layer 2 as required, can easily realize different shock attenuation effects, can simulate the effect of running on multiple different ground, and the elasticity of the bow-shaped reinforcing bar of the unable light control of prior art can't be adjusted according to the demand.
Specifically, wear-resisting layer 1 length direction both ends correspond respectively and are connected 3 length direction both ends on bearing layer, specifically are that 1 four corners department of wear-resisting layer all fixes through connecting piece (threaded fastener such as screw) with 3 four corners departments on bearing layer to make wear-resisting layer 1 be the arch and set up and form arch cavity 4, so that wear-resisting layer 1 is the arch and set up and form arch cavity 4. Compared with the prior art, this application replaces original one deck race board with the three-layer, and is connected between wearing layer 1 and the bearing layer 3 and forms the arch, and set up buffer layer 2 in arch cavity 4, utilize buffer layer 2 to play the cushioning effect, and wearing layer 1 plays wear-resisting effect, and bearing layer 3 plays heavy effect, has so got rid of the setting of bow-shaped reinforcing bar, thereby has reduced greatly and has run the manufacturing degree of difficulty and the weight of board, is favorable to reduce cost.
Specifically, the cushioning layer 2 is disposed within the arcuate cavity 4. In this embodiment, as shown in fig. 2, the top of the buffer layer 2 is connected to the bottom of the wear-resistant layer 1, and the bottom of the buffer layer 2 is connected to the top of the bearing layer 3, and in another embodiment, as shown in fig. 1, the top of the buffer layer 2 is not connected to the bottom of the wear-resistant layer 1, and the bottom of the buffer layer 2 is connected to the top of the bearing layer 3, so that a better buffering effect can be achieved to some extent.
As shown in table 1 below, the thickness of the plate of the buffer layer 2, the magnitude of the load, and the test value of whether to fix the influence of the wear-resistant layer 1 on the sinking of the center point of the wear-resistant layer 1 are shown in table 1:
it can be seen that in table 1, when the plate thickness of buffer layer 2 is 12mm, under various loads, no matter whether fixed wearing layer 1 all has little influence on the central point deflection of wearing layer 1, and when the plate thickness of buffer layer 2 is 15mm, the central point deflection of wearing layer 1 of non-fixed buffer layer 2 is bigger, and it can be seen that to a certain extent, buffer layer 2 does not fix wearing layer 1 and can play a better buffering effect.
Therefore, the thickness of various buffer layers 2 can be tested according to the test, so that the test bed is suitable for simulating various pavements and has a better running effect.
