However, this conventional bolt cover still has the following problems:
1.定位效果不佳，因為只藉由突出部與螺栓孔干涉，並不具有防止螺栓蓋下沉的反作用力，如螺栓蓋下沉就無法與軌條表面平齊，亦造成異物堆積於螺栓蓋上表面。1. The positioning effect is not good, because only the protrusion and the bolt hole interfere, and there is no reaction force to prevent the bolt cover from sinking. If the bolt cover sinks, it cannot be flush with the surface of the rail, and the foreign matter accumulates on the bolt. Cover the surface.
2.因突出部為環狀陣列式排列，故突出部之間仍具有間距，當安裝置螺栓孔中時，該各突出部之間的間距與螺栓孔內徑仍有間隙存在，是以無法完全防止異物進入螺栓孔，而當異物如落入該間隙時相對線性滑軌之滑塊如運行經過也會間接進入滑塊內部，而引響滾動件運行的順暢度。2. Since the protruding portions are arranged in an annular array, there is still a spacing between the protruding portions. When the bolt holes are installed in the device, the spacing between the protruding portions and the inner diameter of the bolt holes still exist, so that it is impossible to The foreign matter is completely prevented from entering the bolt hole, and when the foreign matter falls into the gap, the slider of the relatively linear slide rail enters the inside of the slider indirectly, and the smoothness of the running of the rolling member is caused.
