摘要： A ball bearing slide includes: two outer slides, an inner slide located in the outer slides, two ball cages, and ball rows rollably arranged in the ball cages and supported between the inner slide and the outer slides; wherein the inner slide includes two end parts and a connecting part connecting the two end parts; the ball rows are located between the end parts and the outer slides; the outer slides drive the ball rows to rotate in a pull-out direction and a push-in direction; wherein each of the end parts of the inner slide has a free end; the free end of at least one of the end parts projects towards a centerline of the certain ball row to form a stopping part. During operation, the stopping part prevents the ball rows from falling off from the inner slide under excessive force.

摘要： An improved electric slide rail includes a motor driving device and two slide rail assemblies symmetrically arranged. Every slide rail assembly includes a slide rail (2, 28) and a fixed rail (31, 26), wherein the slide rail (2, 28) is slidably sleeved on the fixed rail (31, 26), a rack housing (1, 10) is sleeved on an outer side of the fixed rail (31, 26), a rack (13, 11) is provided on the rack housing (1, 10), a gear (4, 16) engaged with the rack (13, 11) is mounted on the slide rail (2, 28); the motor driving device is installed on the slide rail (2, 28) through a fixing device and is electrically connected with a controller. The improved electric slide rail further includes a clutch (18, 39, 46) which is electrically connected with the controller, wherein the clutch (18, 39, 46) is arranged at a side where an output shaft of a motor (17, 41, 44) of the motor driving device is provided, and is connected with the slide rail (2, 28) through a linkage structure. The improved electric slide rail has a simple structure, which not only achieves manual and automatic pushing and pulling of the drawer, but also achieves laborsaving manual pushing and pulling and convenient use of the drawer when the motor is powered off. Moreover, the improved electric slide rail is also able to increase the capacity of the drawer and is extended in the service life.
