为了进一步完善，所述内部防尘块由弹性耐磨材料制成，内部防尘块面向滑口侧的面上设有前唇部和后唇部，且前唇部向后方倾斜，后唇部向前方倾斜。虽然滑块安装有端面密封垫片，但是还是会有部分灰尘、粉尘等悬浮颗粒物进入滑块内部，内部防尘块可以将进入滑块内部的悬浮颗粒物收进集尘腔内，避免悬浮颗粒物进入滑块的滚动组件处，更好的避免滚珠的磨损，提高滑块的使用寿命。
进一步完善，所述内部防尘块的前唇部和后唇部与所述导轨侧面接触连接。更好的防止灰尘、粉尘等悬浮颗粒物进入滑块的滚动组件处。
进一步完善，所述内部防尘块下半部分前唇部与后唇部之间开有进尘口，所述内部防尘块下半部设有集尘腔与进尘口连通。使得灰尘、粉尘等悬浮颗粒物有足够多的空间安置，避免内部防尘片收集的悬浮颗粒物过多导致不能持续收集。
进一步完善，所述进尘口四周向外倾斜。可以起到导流作用，使得灰尘能顺利进入集尘腔。
进一步完善，所述端盖内部上端面固定连接有凸块，凸块内侧开有卡接槽，所述顶部防尘片前后两端都固定安装有位于所述卡接槽内的卡块，所述顶部防尘片通过卡块和卡接槽固定在所述滑块本体内侧。
进一步完善，所述顶部防尘片左右两侧都固定连接有突出唇部，突出唇部42与所述导轨8上表面接触连接。利用顶部防尘片下端平面左右两侧突出唇部贴在导轨的顶部，可以避免灰尘、粉尘等悬浮颗粒物从滑块顶部进入到滑块的滚动组件处加剧滚珠的磨损，影响滑块的实用寿命。
进一步完善，所述端盖内部左右两侧都开有第二置放槽，所述端盖内部靠近端面密封垫片的一侧开有和第二置放槽连通的定位槽，所述底部防尘片前后两端固定连接有位于定位槽内侧的定位块，所述底部防尘片通过定位块和定位槽固定在第二放置槽内侧。利用底部防尘片贴在导轨的侧面，从而避免灰尘、粉尘等悬浮颗粒物从滑块底部进入到滑块的滚动组件处加剧滚珠的磨损，影响滑块的实用寿命。
本发明有益的效果是：本发明设有内部防尘块，虽然滑块安装有端面密封垫片，但是还是会有部分灰尘、粉尘等悬浮颗粒物进入滑块内部，内部防尘块可以将进入滑块内部的灰尘、粉尘等悬浮颗粒物收进集尘腔内，避免其进入滑块的滚动组件处，更好的避免滚珠的磨损，提高滑块的使用寿命。本发明还设有顶部防尘片和底部防尘片，利用顶部防尘片和底部防尘片，可以避免灰尘、粉尘等悬浮颗粒物从滑块顶部和底部进入到滑块的滚动组件处加剧滚珠的磨损，影响滑块的实用寿命，使得滑块的滚动组件处得到全方位的防尘保护。
