In the embodiment, the rolling body 2 rolls circularly in the circular track 1011, and the depth of the return section 1011b is greater than that of the load section 1011a, so that the height of the rolling body 2a in the load section is higher than that of the rolling body 2b in the return section, and the sliding object is placed on the rolling body 2a in the load section and is not in contact with the rolling body 2b in the return section, thereby ensuring the normal circulation of the rolling body 2 during the sliding process of the sliding body.
By adopting the sliding wear-proof device in the embodiment, when a sliding object is placed on the rolling body 2a in the load section, the rolling body 2a in the load section is pressed by the sliding object, when the sliding object is pushed, the sliding object generates a forward static friction force on the rolling body 2a in the load section, the static friction force drives the rolling body 2a in the load section to roll forward along the load section 1011a, meanwhile, because the rolling body 2b in the return section is zero-contacted with the sliding object, is not pressed and can roll freely, the rolling of the rolling body 2a in the load section can push the rolling of the similar rolling body 2, and further push the rolling of the turning section 1011c and the rolling body 2b in the return section, thereby all the rolling bodies 2 are promoted to circulate in the circulating track 1011, the sliding friction of the sliding object is converted into rolling friction, the friction of the sliding object under the same pressure is greatly reduced, the sliding is convenient, time-saving and labor-saving, while reducing wear.
The rolling body 2 of the sliding anti-wear device circularly and continuously rolls in the circulating track 1011, so that the sliding object can continuously slide, the application range is wide, and the sliding anti-wear device can be used for sliding the sliding object with a larger area. When the sliding object slides, all the rolling bodies 2 circularly roll in the circulating track 1011, the circulating track 1011 adopts the structure, the rolling bodies 2 in the load section 1011a are not fixed, all the rolling bodies 2 can circularly enter, and the rolling bodies 2 in the non-load section 1011a are in a free state, so that the concentrated continuous stress of local sections of the rolling bodies 2 is prevented, the local abrasion of the rolling bodies 2 is reduced, and the service life of the sliding anti-abrasion device is prolonged.
In the present exemplary embodiment, the rolling element 2 makes a transition between the load section 1011a and the return section 1011b via the deflection section 1011 c.
As shown in fig. 5, a connecting line between the lowest point C of the load section and the lowest point D of the return section forms an included angle α with the horizontal line E, where α is greater than or equal to 5 ° and less than or equal to 20 °, and preferably, α is 10 °, at this time, as shown in fig. 3, a contact portion a of the rolling body 2a in the load section and the sliding object is also higher than a highest point B of the rolling body in the return section, and a connecting line between the two forms an included angle α with the horizontal line E.
If α is too small, the heights of the rolling bodies 2a in the load section and the rolling bodies 2b in the return section are too close, and the rolling bodies 2a in the load section are extruded and deformed when being pressurized, so that the sliding objects are in contact with the rolling bodies 2b in the return section, and the advancing direction of the rolling bodies 2b in the return section is opposite to the advancing direction of the rolling bodies 2a in the load section due to the fact that the rolling bodies 2 roll circularly, and smooth sliding of the sliding objects is hindered; or the sliding object contacts with both the inner rolling body 2a of the load section and the inner rolling body 2b of the return section, so that static friction force is generated, and the directions of the static friction force point to the sliding direction of the sliding object, so that the section rolling bodies 2 move towards each other in the circulating track 1011, and the circulation of the rolling bodies 2 is blocked.

The rolling body 2 is preferably a rolling ball, in order to avoid the rolling ball in the load section 1011a from falling out of the long hole 1021, the width of the long hole 1021 is smaller than the diameter of the rolling ball, and meanwhile, in order to prevent the rolling ball from greatly shaking and being damaged in the carrying process and giving out abnormal sound, when the sliding wear-resistant device is horizontally placed, the long hole 1021 and the rolling ball are in clearance fit, namely the width of the long hole 1021 is slightly larger than the diameter of the horizontal section of the rolling ball at the long hole 1021.
In order to prevent the rolling balls from being stuck at the turning section 1011c, as shown in fig. 1 and 2, an avoiding hole 1022 is formed at a position of the upper cover 102 corresponding to the turning section 1011c, the avoiding hole 1022 is communicated with the long hole 1021, and the width of the avoiding hole 1022 is also smaller than the diameter of the rolling balls.
