Detailed Description

In order to make the purposes, technical schemes and advantages of the present disclosure clearer, embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It is noted that the embodiments in the present application and the features in the embodiments may be combined with each other arbitrarily if there is no conflict.

Example 1:

A slide rail assembly provided by the present disclosure, as shown in FIGS. 1 to 7, includes: a slide rail 100 provided with a sliding chute 110 having an upwardly opened notch and a stopper 120; a pulley device including a pulley 210 and a mounting seat 220, the pulley 210 being uprightly disposed and rotatably mounted on the mounting seat 220, and the pulley 210 being hung over the sliding chute 110 and being movable along a length direction of the sliding chute 110; and a limiter 300 fixed on the mounting seat 220, the limiter 300 being provided with a limiting portion 310 which is located below the stopper 120. The stopper 120 prevents the pulley 210 from upwardly moving out of the sliding chute 110 by limiting the upward movement of the limiting portion 310.
In the slide rail assembly, the notch of the sliding chute 110 in the slide rail 100 faces upward, the pulley 210 of the pulley device is hung over the sliding chute 110, and the limiter 300 is fixed on the mounting seat 220 of the pulley device. The limiting portion 310 of the limiter 300 is located below the stopper 120 of the slide rail 100, and the stopper 120 limits the upward movement of the limiting portion 310, so that the pulley 210 is prevented from upwardly moving out of the sliding chute 110 from the notch of the sliding chute 110. The pulley 210 may not upwardly move out of the sliding chute 110 when moving along the sliding chute 110. Therefore, the slide rail assembly is applied to a shower room without a problem that a glass door falls and breaks, and the shower room is safer when in use.
In an exemplary embodiment, as shown in FIGS. 4, 6 and 7, the slide rail assembly further includes a buffer 400 disposed on the limiting portion 310 to prevent the limiting portion 310 from colliding with the stopper 120 rigidly, so that the limiter 300 and the slide rail 100 are less likely to be damaged during use. The buffer 400 may be disposed as a buffer sleeve, and the buffer sleeve is sleeved on the limiting portion 310, so that the buffer sleeve is not easy to fall off during use.
In an exemplary embodiment, as shown in FIGS. 1 and 2, the slide rail 100 is further provided with a guiding and limiting groove 130. The guiding and limiting groove 130 is parallel to the sliding chute 110 and has the same length as the sliding chute 110. The limiter 300 is further provided with a guiding and limiting portion 320 which extends into the guiding and limiting groove 130 and is movable along the guiding and limiting groove 130. A groove wall of the guiding and limiting groove 130 limits the guiding and limiting portion 320 to move along a width direction of the sliding chute 110, so as to prevent the pulley 210 from swinging in the width direction of the sliding chute 110, and ensure that the limiting portion 310 is always located just below the stopper 120, so that the pulley 210 is less likely to move out of the sliding chute 110 from the notch of the sliding chute 110, and the shake amount of the pulley device during use is also smaller.
In an exemplary embodiment, the slide rail assembly further includes two sets of dampers 500, which are fixed at two ends of the guiding and limiting groove 130 (understood with reference to FIGS. 1 and 2), respectively, and are used to slow down the guiding and limiting portion 320, that is, to slow down the pulley device when the guiding and limiting portion 320 moves to the end of the traveling distance (that is, each end of the guiding and limiting groove 130). The two sets of dampers 500 may be two dampers 500 or four dampers 500, which can be reasonably selected according to the number of movable glass doors.
In an example, as shown in FIG. 5, each damper 500 includes: a body 510 fixed at the end of the guiding and limiting groove 130, the body 510 being provided with a sliding groove 511; and a damping slider 520 disposed in the sliding groove 511 and movable along the sliding groove 511. The sliding groove 511 is parallel to the slide rail 100, and the length of the sliding groove 511 is far less than that of the slide rail 100. When the guiding and limiting portion 320 moves to the end of the traveling distance, the guiding and limiting portion 320 enters the sliding groove 511, and then pushes the damping slider 520 to move along the sliding groove 511 together, and the friction force between the damping slider 520 and the sliding groove 511 slows down the guiding and limiting portion 320. The body 510 can be fixed on a bottom wall of the guiding and limiting groove 130 by screws or fastening screws after the determination of its position at the end of the guiding and limiting groove 130 as required. The guiding and limiting groove 130 may be disposed as a T-shaped groove.
In an example, as shown in FIGS. 1 and 5, the damping slider 520 is provided with a mating notch 521. When the guiding and limiting portion 320 moves from the middle of the movement traveling distance towards the end of the movement traveling distance, the guiding and limiting portion 320 may enter the sliding groove 511 and then be snapped into the mating notch 521. When the guiding and limiting portion 320 moves from the end of the movement traveling distance towards the middle of the movement traveling distance, the guiding and limiting portion 320 may move out of the mating notch 521 and then slide out of the sliding groove 511, thus separating from the damper 500 and realizing quick door opening.
In an exemplary embodiment, as shown in FIGS. 1 and 2, the guiding and limiting groove 130 is located at the top of the slide rail 100, with the notch facing upwards, and the notch of the sliding groove 511 also faces upwards. The sliding chute 110 and the stopper 120 are located at the same side of the slide rail 100, and the stopper 120 is located above the sliding chute 110. The stopper 310 and the guiding and limiting portion 320 are both located at the same side of the limiter 300, and the limiting portion 310 is located below the guiding and limiting portion 320. Such structure is applied for a shower room to make the operation more simple and convenient for operators.
In an example, as shown in FIGS. 1, 2 and 4, the limiting portion 310 is a horizontally arranged limiting plate, which is located just below the stopper 120. The distance between the limiting plate and the stopper 120 is a, the depth of the pulley 210 sinking into the sliding chute 110 is b, wherein a is less than b. The length of the stopper 120 is the same as that of the sliding chute 110. Therefore, the pulley 210 may not upwardly move out of the sliding chute 110.
In an example, as shown in FIGS. 1, 2 and 4, the guiding and limiting portion 320 includes a horizontally arranged connecting arm and a vertically disposed guiding and limiting arm. An upper end of the guiding and limiting arm is connected to a side surface of the limiter 300 by the connecting arm, and a lower end of the guiding and limiting arm extends downward into the guiding and limiting groove 130.
In an exemplary embodiment, as shown in FIGS. 1, 2, 3, 6 and 7, the mounting seat 220 includes: a pulley seat 230, two sets of pulleys 210 spaced horizontally being both rotatably mounted on a side of the pulley seat 230 facing the slide rail 100; a door body connecting seat 240. The pulley seat 230 is located between the door body connecting seat 240 and the slide rail 100. The pulley seat 230 can be mounted at a side of the door body connecting seat 240 in a horizontally swinging manner by bolts, so that the angles of the two sets of pulleys 210 can be adjusted in a horizontal direction, which can better ensure the smooth movement of the two sets of pulleys 210 along the slide rail 100. The door body connecting seat 240 is used to be assembled with a door body to form a sliding door structure. The door body may be disposed as a glass door.
In the slide rail assembly, the pulley device is firstly hung over the slide rail 100, then the limiter 300 is mounted on the slide rail 100, and finally, the limiter 300 and the pulley seat 230 are fixed together by screws.
In an exemplary embodiment, as shown in FIGS. 6 and 7, the door body connecting seat 240 includes a first connecting seat 241, a second connecting seat 242, a spacer 243 and a decorative cover 244 and the like. After the first connecting seat 241, the second connecting seat 242 and the spacer 243 are mounted on the glass door, a screw is screwed on the first connecting seat 241 after passing through the second connecting seat 242, the spacer 243 and the glass door, and finally the decorative cover 244 is mounted on the second connecting seat 242.

Example 2:

A shower room (not shown in the figures) provided by the present disclosure includes a door body and the slide rail assembly of any of aforementioned embodiments, and the mounting seat is assembled with the door body.
In an exemplary embodiment, the door body is provided as a glass door.
In conclusion, in the slide rail assembly provided by the embodiments of the present disclosure, the notch of the sliding chute in the slide rail faces upward, the pulley of the pulley device is hung over the sliding chute, the limiting portion of the limiter is located below the stopper of the slide rail, and the stopper limits the upward movement of the limiting portion, so that the pulley is prevented from upwardly moving out of the sliding chute from the notch of the sliding chute, and the pulley may not upwardly move out of the sliding chute when moving along the sliding chute. Therefore, the slide rail assembly is applied to the shower room without a problem that the glass door falls and breaks, and the shower room is safer when in use.
