It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 to 9 show a preferred embodiment of the present invention.
The sliding rail assembly 100 in this embodiment includes a fixed rail 110, an adjustment rail 120, and a sliding rail 130. The adjusting rail 120 is slidably connected to the fixed rail 110, and the adjusting rail 120 is configured to be slidable along the length direction of the fixed rail 110. The adjustment rail 120 is provided with a gear member 121. The sliding rail 130 is slidably connected to the adjusting rail 120, and the sliding rail 130 is configured to be slidable along the length direction of the adjusting rail 120. Namely, the adjusting rail 120 has a first-stage sliding stroke relative to the fixed rail 110, the sliding rail 130 has a second-stage sliding stroke relative to the adjusting rail 120, and the overall stroke of the slide rail assembly 100 is the sum of the first-stage stroke and the second-stage stroke.
The slide rail assembly 100 further includes a limiting portion 140, and the limiting portion 140 is detachably disposed on the fixed rail 110, and may be clamped or inserted. The position-limiting part 140 has at least two fixing positions arranged in a row along the length direction of the fixing rail 110 on the fixing rail 110, and a user can install the position-limiting part 140 at any one of the fixing positions according to actual needs. The limiting portion 140 is configured to abut against the gear 121 during the sliding stroke of the adjusting rail 120 relative to the fixed rail 110, so as to limit the sliding stroke of the adjusting rail 120 relative to the fixed rail 110. That is, when the adjusting rail 120 slides relative to the fixed rail 110 in one direction and the gear 121 of the adjusting rail 120 abuts against the stopper 140, the adjusting rail 120 cannot slide continuously, and the fixing positions of the stopper 140 are arranged in the longitudinal direction of the fixed rail 110, so that the installation position of the stopper 140 on the fixed rail 110 determines the length of the slidable distance of the adjusting rail 120 on the fixed rail 110. The slide rail assembly 100 in this embodiment is provided with a two-stage stroke, wherein the stroke between the sliding rail 130 and the adjusting rail 120 is used for limiting the minimum stroke of the slide rail assembly 100, and the fixing position of the limiting portion 140 is used for limiting the maximum stroke of the slide rail assembly 100, so that a user (the user refers to a person who uses a final product, and a manufacturer who purchases the slide rail assembly 100 as an accessory) can adjust the stroke of the slide rail assembly 100 as required during the use process, and the adaptability of the slide rail assembly 100 is enhanced.
In order to realize the sliding connection, in one embodiment, a first sliding groove 112 extending along the length direction of the fixed rail 110 may be provided, and the adjusting rail 120 includes a first sliding portion 122 embedded in the first sliding groove 112, and the first sliding portion 122 is configured to slide in the first sliding groove 112. Any known sliding structure, such as balls, rollers, and bearings, may be provided between the fixed rail 110 and the adjustment rail 120. Specifically, the length of the first sliding groove 112 may be equal to the length of the fixed rail 110, and the length of the first sliding portion 122 may also be equal to the length of the adjusting rail 120, and when the length of the first sliding groove 112 is equal to the length of the fixed rail 110 and the length of the first sliding portion 122 is equal to the length of the adjusting rail 120, the maximum length of the first sliding stroke is the length of the fixed rail 110 plus the length of the adjusting rail 120. In order to stabilize the sliding process of the first sliding portion 122 in the first sliding groove 112, only the length of the first sliding groove 112 may be set as the effective sliding length, i.e. the maximum length of the first sliding stroke is equal to the length of the first sliding groove 112. That is, the adjusting rail 120 can only slide from the initial state shown in fig. 1 to the longest extended state shown in fig. 6, and when the adjusting rail 120 is located at the initial state position shown in fig. 1 relative to the fixed rail 110, it cannot slide in the direction opposite to the first direction.
The first sliding groove 112 of the fixed rail 110 may be formed by integrally bending or pressing the fixed rail 110 in the form of a plate, or may be formed by machining and cutting the block-shaped fixed rail 110, as shown in fig. 4 or 8, the first sliding groove 112 is formed by bending the fixed rail 110 in the form of a plate, and is formed with a flange 113 defining the first sliding groove 112. The first sliding portion 122 of the adjustment rail 120 may be a sheet-shaped curved edge that can be fitted into the first sliding groove 112, or may be a block-shaped protrusion. And the first sliding portion 122 may be integrally bent or press-molded by the adjustment rail 120 in the form of a plate. The specific structures of the first sliding groove 112 and the first sliding portion 122 are well known in the art, and are not described herein.
The gear 121 is configured to abut against the limiting portion 140, and after the slide rail assembly 100 is assembled, once a foreign object is attached to the slide rail assembly 100, the foreign object easily blocks the sliding of the gear 121, so that the first sliding stroke of the slide rail assembly 100 is reduced (in this process, the foreign object serves as the limiting portion 140 abutting against the gear 121). In order to avoid the above-mentioned drawbacks, in an embodiment, the gear position member 121 may be disposed on the first sliding portion 122, and the first sliding portion 122 is disposed on the first sliding groove 112, so that the gear position member 121 slides in the first sliding groove 112, and the first sliding groove 112 protects the sliding of the gear position member 121, and prevents foreign objects from obstructing the movement of the gear position member 121. After the gear piece 121 is disposed in the first sliding groove 112, in order to enable the limiting portion 140 to abut against the gear piece 121, at least two limiting holes 111 arranged in a row along the length direction thereof may be disposed in the sliding groove, and the limiting portion 140 is configured to be partially inserted into the first sliding groove 112 through the limiting holes 111. Each of the limiting holes 111 is a fixing position of the limiting portion 140 on the fixing rail 110, and when the arrangement position of the limiting portion 140 is changed from one of the limiting holes 111 to another limiting hole 111, the length of the first sliding stroke is correspondingly changed. As shown in fig. 3, five limit holes 111 are formed in the fixed rail 110, so that five parameters corresponding to the length of the first sliding stroke can be changed.
In order to make the position-limiting portion 140 not easily slip out of the position-limiting hole 111 after being inserted into the position-limiting hole 111, in an embodiment, as shown in fig. 5, the position-limiting portion 140 may include an extending end 141 for being inserted into the sliding groove, and a strip-shaped clamping block 144 perpendicular to the extending end 141 is connected to an end of the extending end 141. The limiting hole 111 is also in a shape of a strip. The catching piece 144 is configured to pass through the position-limiting hole 111 only when the length direction thereof is parallel to the length direction of the position-limiting hole 111. After the clamping block 144 passes through the limiting hole 111, the user drives the limiting part 140 to rotate integrally relative to the limiting hole 111, and the clamping block 144 cannot exit from the limiting hole 111, so that the clamping block 144 cannot slide out of the limiting hole 111 after being inserted into the limiting hole 111, and the clamping block 144 is positioned more stably.
On the other hand, in order to make the position-limiting portion 140 not completely fall into the first sliding groove 112, in an embodiment, the position-limiting portion 140 may further include an outer end 142 connected to an end of the extending end 141 away from the clamping block 144, an abutting flange 143 is disposed between the extending end 141 and the outer end 142, and the abutting flange 143 is configured to be unable to pass through the position-limiting hole 111. That is, after the engaging block 144 passes through the limiting hole 111, the outer end 142 of the limiting portion 140 can only be located outside the first sliding groove 112 due to the limitation of the abutting flange 143.
The limiting portion 140 shown in fig. 1 to 6 is inserted into the fixing rail 110, and after the limiting portion 140 is inserted into each limiting hole 111, the length of the primary sliding stroke changes in stages. In some applications of the slide rail assembly 100, the stroke length is required to be linearly varied. In order to achieve the above purpose, in an embodiment, as shown in fig. 7 to 9, the position-limiting portion 150 may also be a sliding member that is clamped on the fixed rail 110 and slides along the length direction of the fixed rail 110. The sliding rail assembly 100 further includes a fastening member, the fastening member is used for fixing the limiting portion 150 on the fixed rail 110, and when the limiting portion 150 is fixed on the fixed rail 110, it can no longer slide relative to the fixed rail 110, so that it can limit the sliding stroke of the adjusting rail 120 relative to the fixed rail 110, and the purpose of changing the overall stroke of the sliding rail assembly 100 is achieved. In particular, since the fastening member can fix the position-limiting portion 150 at any position of the fixed rail 110 along the length direction thereof (i.e., any position of the fixed rail 110 along the length direction can be regarded as the fixed position of the position-limiting portion 150), the stroke length of the slide rail assembly 100 can be changed linearly, thereby further enhancing the practicability of the slide rail assembly 100.
Specifically, as shown in fig. 9, the limiting portion 150 may be clamped on the flange 113 defining the first sliding groove 112 and can slide along the length direction of the flange 113, and the limiting portion 150 includes an abutting end 152 extending into the first sliding groove 112, and the abutting end 152 is used for abutting against the gear position 121 disposed in the first sliding groove 112.
The fastening element (not shown in the figures) may be a set screw, the position-limiting portion 150 is provided with a threaded hole 151 in threaded connection with the set screw, and the set screw is used for fastening the position-limiting portion 150 to the flange 113 of the fixed rail 110, so that the fastening element cannot slide relative to the fixed rail 110.
In one embodiment, in order to increase the length of the first sliding stroke as much as possible, the gear position member 121 may be disposed at an end of the adjustment rail 120 in the length direction thereof, and particularly, may be disposed at an end of the first sliding portion 122 of the adjustment rail 120 in the length direction. The shift element 121 may be a protrusion connected to the first sliding portion 122, or may be a folded edge integrally formed with the first sliding portion 122 as shown in fig. 2.
The sliding fit of the adjustment rail 120 and the sliding rail 130 is similar to the sliding fit of the fixed rail 110 and the adjustment rail 120, that is, the adjustment rail 120 may have a second sliding groove 123 extending along the length direction thereof, and the sliding rail 130 includes a second sliding portion 131 embedded in the second sliding groove 123, and the second sliding portion 131 is configured to slide in the second sliding groove 123. In order to facilitate the connection of the sliding rail 130 with other components, the adjusting rail 120 may be disposed between the fixed rail 110 and the sliding rail 130, and of course, in other embodiments, the sliding rail 130 may be disposed between the fixed rail 110 and the adjusting rail 120.
In use, the track assembly 100 can be used to connect the fixed track 110 to a fixed component, such as a cabinet of a drawer cabinet, and the sliding track 130 to a sliding component, such as a drawer of a drawer cabinet (in other embodiments, the fixed track 110 can be connected to the sliding component, and the sliding track 130 can be connected to the sliding component). During the process of drawing the drawer, the user can slide the adjusting rail 120 and the sliding rail 130 relatively, and can slide the fixed rail 110 and the adjusting rail 120 relatively. When the fixed rail 110, the adjusting rail 120 and the sliding rail 130 are at the relative positions as shown in fig. 1, the drawer is in a closed state; when the drawer is pulled to the maximum opening position, the adjusting rail 120 and the fixed rail 110 are at the relative position as shown in fig. 6, and at this time, the gear 121 of the adjusting rail 120 abuts against the limiting part 140 on the fixed rail 110.
The second aspect of the present invention further provides a refrigerator, which includes a storage drawer, wherein the storage drawer is connected to any one of the slide rail assemblies 100, and specifically can be connected to the slide rail 130 of the slide rail assembly 100, and the fixed rail 110 of the slide rail assembly 100 can be connected to the inner container of the storage compartment of the refrigerator.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
