Service life.To guarantee that rolling element 2 is not fallen out of slider body 1, holder is provided between slider body 1 and sliding rail
12 and lower retainer 13, holder 12 and lower retainer 13 are fixed on the both ends end cap of slider body 1 by card slot.Upper holding
Frame 12 is used to support the rolling element 2 of the first raceway 113, makes it along 113 loopy moving of the first raceway, reduces it from sliding block sheet
The landing of body 1.Lower retainer 13 is used to support the rolling element 2 of the second raceway 114, recycles it along the second raceway 114 and moves
It is dynamic, reduce the landing of its from slider body 1.The use of retainer can make rolling element 2 along 1 loopy moving of slider body, subtract
The landing of rolling element 2 is lacked.In the prior art in order to keep rolling element 2 not slide, usually using holder 12, middle guarantor
Hold frame and lower retainer 13.Middle holding is placed between the first raceway 113 and the second raceway 114, is the first raceway 113 and second
Rolling element 2 in raceway 114 provides support force, reduces the landing of its from slider body 1.In the present solution, being kept to reduce
The use of frame reduces the installation difficulty of retainer, is connected between the first raceway 113 and the second raceway 114 by boss 115, convex
Platform 115 is an integral molding structure with slider body 1.The setting of boss 115 can substitute middle retainer in the prior art and fix
Rolling element 2, reduces the use of retainer, and then reduces the probability that retainer is easy to happen deformation in use,
The operation smoothness of linear slider is improved, and then improves the service life of linear slider.In the utility model, by being provided with half
The boss 115 of round raceway and connection half-round race, reduces the use of retainer, reduces retainer and slider body 1
Frictional force, improve the service life of slider body.
Above-mentioned slider body 1 is not limited only to a type of slider body 1.In order to improve the slider body 1 of each type
Service life, in the present embodiment, slider body 1 includes flange type sliding block ontology and square slider ontology.Flange type sliding block sheet
Body and square slider ontology may be provided with half-round race and boss 115.In order to further increase the use longevity of slider body 1
It orders, in the present embodiment, boss 115 is set as bucking ladder.The boss 115 of bucking ladder not only can connect the first raceway 113 and
Two raceways 114 can also reduce the contact area of boss 115 Yu slider body 1, improve the service life of slider body 1.
In order to reduce the friction of rolling element 2 Yu raceway, in the present embodiment, the first raceway 113 and the second raceway 114 it is straight
Diameter size and the diameter dimension of rolling element 2 match.The diameter dimension of first raceway 113 and the second raceway 114 is more than or equal to
The diameter dimension of rolling element 2 can not only make rolling element 2 mobile in the first raceway 113 and the second raceway 114, can also subtract
The frictional force of few rolling element 2 and slider body 1, improves the service life of slider body 1.
In order to allow slider body 1 and guide rail cooperates composition line slide rail, in the present embodiment, slider body 1 is also set up
There is mounting hole 14, slider body 1 is connect with sliding rail by mounting hole 14.In use process, slider body 1 and sliding rail pass through installation
Hole 14 connects, and is flexibly connected slider body 1 on the slide rail, and can move along sliding rail.
Since holder 12 is fixed on the bottom surface 111 of sliding slot 11, the both ends of holder 12 are separately connected the first raceway
Rolling element in 113 provides support force for the rolling element 2 in the first raceway 113.Lower retainer 13 is fixed on sliding slot 11
Two side walls 112 provide support force for the rolling element 2 in the second raceway 114.In order to make the first raceway 113 and the second raceway
Rolling element 2 in 114 can be moved along respective raceway, avoid its landing, in the present embodiment, the quantity of lower retainer 13
Quantity ratio with holder 12 is 2:1.Under the action of holder 12 and lower retainer 13, allow 2 edge of rolling element
Respective raceway shuttling movement.
