A steel ball retainer locking mechanism of a slide rail includes an engaging block, a release hole, a locking hook, a synchronized hook and a releasing hook. The slide rail includes an outer rail, a steel ball retainer and an inner rail, and the engaging block has a synchronized engaging block and a locking block separated with an interval apart from each other, and the synchronized engaging block has a releasing portion and a synchronized hook portion corresponding to the outer rail and the inner rail respectively, and the locking block has a locking portion and a propping portion corresponding to the outer rail and the inner rail respectively. When the inner rail is pulled outward, the engaging block is locked by the locking hook. After the releasing hook pushes the propping portion, the engaging block is unlocked.

A micro linear slide rail assembly and a slider are disclosed. The slider straddles a slide rail. A rolling member is disposed between the slide rail and the slider. The slider is linearly displaced on the slide rail by rolling of the rolling member. The slider includes a main body, a frame coupled to the main body, and two end caps connected to two opposite ends of the main body. The slider has a first unloaded track surface. The first unloaded track surface surrounds an accommodating area. A first engaging portion extends from a lower edge of the accommodating area. The frame has a second unloaded track surface. The frame is mounted to the main body through a second engaging portion to be engaged with the first engaging portion. The first unloaded track surface and the second unloaded track surface are combined to form an unloaded path.

A guide apparatus is provided which can increase a holding force that holds a table, a drawer, a cabinet, a device, or the like at a predetermined position. An engagement body (43) is placed on a second member (42b). A pair of plate spring portions (44a and 44b) is placed on a first member (41) in such a manner as to sandwich the engagement body (43). The pair of plate spring portions (44a and 44b) bend in such a manner that a minimum dimension between the pair of plate spring portions (44a and 44b) is smaller than a dimension (length) of the engagement body (43). In a state where the engagement body (43) has gone beyond a minimum dimension position (53) between the pair of plate spring portions (44a and 44b) and the second member (42b) is being held at a predetermined position on the first member (41), the minimum dimension between the pair of plate spring portions (44a and 44b) is smaller than the dimension (length) of the engagement body (43), and both end portions (44a1, 44a3, 44b1, and 44b3), in a length direction, of the plate spring portions (44a and 44b) are supported by the first member (41).

A slide unit for a drawer includes a middle slide rail molded through a simple process to enhance productivity. The middle slide rail of the slide unit has an improved structure to enable each of a main body-side fixed rail and a drawer-side fixed rail to more smoothly slide on the middle slide rail.

The present disclosure relates to the technical field of vehicle-mounted movable drawers, and in particular, to a drawer track combining extruded aluminum profiles and spherical bearings, and a vehicle-mounted storage drawer. The drawer track includes a movable sliding rail plate and a bearing fixing plate which are mutually guided and are in sliding fit; the movable sliding rail plate and the bearing fixing plate are both made of extruded aluminum profiles; a hollow sliding rail is extruded and formed on one side of the movable sliding rail plate, and curved slideways are formed by inward sinking along an upper part and a lower part of the hollow sliding rail; the bearing fixing plate is rotatably connected with a plurality of outer spherical bearings corresponding to the curved slideways; the bearing fixing plate is extruded to form a thickened bar.

In order to provide drawer guide for guiding a drawer which is extendable out of a carcass in an extension direction and which is of stable configuration and in particular enables the reliable guidance of drawers with an unfavorable width-depth ration, it is proposed that the drawer guide to comprises a guidance unit configured as a vertical guidance unit and a guidance unit configured as a lateral guidance unit, wherein the two guidance units each comprise a carcass-side guidance rail and a drawer-side guidance unit mounted on rolling bodies and wherein the two guidance units are coupled to each other by means of a coupling device.

A three-rows-of-ball bearings sliding rail is disclosed. An inner sliding rail body is supported in outer sliding rail bodies through three rows of support ball bearings which are arranged in parallel in a lengthwise direction of the inner sliding rail body. The three rows of support ball bearings are respectively limited within a length range of the outer sliding rail bodies via ball retainers. Each of the outer sliding rail bodies includes a bottom plate, a first side wall and a second side wall which are respectively located at two sides in a widthwise direction of the bottom plate, are integrally formed with the bottom plate and extended in a lengthwise direction of the bottom plate. The first side wall includes a first arm and a supporting part which is bent inwardly and extends horizontally from a bottom end of the first arm.

A slide rail assembly includes a first rail, a second rail and a mounting member. The mounting member is arranged with a third rail and a fourth rail. Wherein, the third rail is movable relative to the first rail, and the second rail is movable relative to the fourth rail.

A slide rail assembly includes a first rail, a second rail, a mounting member, a third rail and a fourth rail. The mounting member includes a first part, a second part and a third part. The first and second parts are connected to the third parts and are respectively extended along different directions. The mounting member has a first side and a second side. The third rail is connected to the first part of the mounting member and located at the first side of the mounting member. The third rail is movable relative to the first rail. The fourth rail is connected to the second part of the mounting member and located at the second side of the mounting member. The second rail is movable relative to the fourth rail.

A drawer glide mechanism can include a first elongate guide member, a second elongate guide member, a ball bearing component, a v-notch socket, a release mechanism, and/or a roller support. The first elongate guide member can include a distal end that is configured to fit within an opening in the v-notch socket. The drawer glide mechanism can further include one or more floating members and fixed members. In some cases, the drawer glide mechanism includes a release member configured to facilitate separation of the first and second elongate guide members when actuated and to inhibit or prevent accidental separation of the first and second elongate guide members.
