Description

Technical Field

[0001] The utility model relates to a furniture hardware accessory, in particular to a slide rail assembly. Background Art

[0002] Slide rails, also known as guide rails or runners, are hardware accessories fixed to furniture drawers to allow the cabinet or panel to move in and out. They are suitable for connecting wooden or steel cabinets, such as cabinets, furniture, document cabinets, and bathroom cabinets. Slide rails are mainly divided into roller slides, steel ball slides, gear slides, and damping slides.

[0003] The installation of traditional slide rails is achieved by using screws. Slide rails can be divided into two-section slide rails and three-section slide rails according to whether they are fully extended. Among them, the three-section slide rails are composed of an outer rail, a middle rail and an inner rail that are connected. Traditional three-section slide rails are generally provided with through holes on the outer rail and the inner rail. When the slide rails are installed, the screws pass through the through holes and self-tap the screw threads on the plate to connect the screws to the plate, so that the outer rail is installed on the cabinet body and the inner rail is installed on the drawer, and then the drawer is installed through the cooperation of the outer rail and the inner rail. This installation method is not only inefficient and laborious, but also the screws are prone to tilt and swing during installation, causing the screws to deviate from the preset point, resulting in the slide rail being misaligned, and the drawer finally installed on the cabinet body having poor aesthetics.

[0004] In order to solve the drawbacks of traditional slide rail installation, the utility model patent with publication number CN220343976U discloses "A slide rail assembly". The slide rail assembly is respectively provided with mounting parts on the outer rail and the inner rail, and embedded parts are opened in advance on the cabinet body. Then, when the slide rail assembly is installed, it is only necessary to install the mounting parts into the embedded parts to realize the assembly of the slide rail assembly and the cabinet body. Compared with the traditional slide rail installation method, this design can significantly improve the installation efficiency and convenience. However, when the mounting holes on the cabinet body are opened, due to processing errors, the center points of multiple mounting holes on the same plate are difficult to ensure to be distributed on the same horizontal plane, that is, the embedded parts cannot be distributed on the same horizontal plane. The mounting parts on the slide rail also have this problem. When the longitudinal deviation of multiple embedded parts or multiple mounting parts is more obvious, the installed outer rail or inner rail will appear tilted. This will not only increase the difficulty of assembling the outer rail and the inner rail, but also the final assembled drawer will appear tilted or there will be a significant gap between the upper and lower drawers, resulting in poor aesthetics.

[0005] Therefore, it is necessary to provide a technical solution to solve this problem. Utility Model Content

[0049] In view of the problems existing in the existing quick-install slide rail assembly, this embodiment provides a slide rail assembly, such as Figures 1-11 As shown, the slide rail assembly includes an outer rail 1, a middle rail 2, an inner rail 3 and two first mounting members 4;

[0050] The outer rail 1 includes a first fixed plate 11 and two first vertical wall plates 12. The first fixed plate 11 has a first sliding surface 111 and a first mounting surface 112 opposite to each other. The two first vertical wall plates 12 are fixedly connected to the opposite side edges of the first sliding surface 111, and a first sliding groove is formed from the leading end of the first vertical wall plate 12 along the trailing end of the first vertical wall plate 12. Two first through holes are defined in the first fixed plate 11.

[0051] The middle rail 2 includes a second fixed plate 21 and two second vertical wall plates 22. The second fixed plate 21 has a second sliding surface 211 and a first disassembly surface 212 opposite to each other. The two second vertical wall plates 22 are fixedly connected to the opposite side edges of the first disassembly surface 212 respectively. A second sliding groove corresponding to the first sliding groove is formed from the head end of the second vertical wall plate 22 along the tail end of the second vertical wall plate 22. A first sliding member 6 is provided between the first sliding groove and the second sliding groove. The middle rail 2 can be slidably provided on the outer rail 1 through the first sliding member 6; the second vertical wall plate 22 of the middle rail 2 is formed with a fourth sliding groove corresponding to the third sliding groove; the first disassembly surface 212 of the middle rail 2 is provided with a disassembly portion;

[0052] The inner rail 3 includes a third fixing plate 31 and two third vertical wall plates 32. The third fixing plate 31 has a second disassembly surface 311 and a second installation surface 312 opposite to each other. The two third vertical wall plates 32 are fixedly connected to the opposite side edges of the second disassembly surface 311, and a third sliding groove is formed from the head end of the third vertical wall plate 32 along the tail end of the third vertical wall plate 32. A second sliding member 7 is provided between the third sliding groove and the fourth sliding groove, and the inner rail 3 can be slidably set on the middle rail 2 through the second sliding member 7. The second disassembly surface 311 of the inner rail 3 is provided with a blocking portion, and the middle rail 2 and the inner rail 3 can be detachably installed by cooperating with the disassembly portion and the blocking portion.

[0053] Two first mounting members 4 are provided at the two first through holes in a one-to-one correspondence. The first mounting member 4 includes a fastening portion 41, an eccentric portion 42, and a limiting portion 43 connected in sequence. The fastening portion 41 is used to be embedded in the first mounting hole of the cabinet. The eccentric portion 42 is used to cooperate with the hole wall of the first through hole to limit the outer rail 1 from moving in the vertical direction relative to the eccentric portion 42. The limiting portion 43 is provided on one side of the first sliding surface 111 of the first fixing plate 11 to limit the outer rail 1 from moving in the left and right direction.

[0054] Among them, the first mounting member 4 can rotate in the first mounting hole so that the eccentric portion 42 drives the outer rail 1 to move in the up and down directions for position adjustment. Of course, when the first mounting member 4 rotates, the eccentric portion 42 will also drive the outer rail 1 to produce a front-to-back offset, but the offset is extremely small and will not affect the use of the drawer. Therefore, the offset of the outer rail 1 in the front-to-back direction can be ignored; the first mounting member 4 is also provided with a locking portion 44 for limiting the rotation of the first mounting member 4 after the outer rail 1 completes the position adjustment.

[0055] The installation process of the outer rail 1 and the cabinet body in the slide rail assembly of the present invention is as follows: the first fixing plate 11 is placed against the cabinet body, and each first through hole corresponds to each first mounting hole on the cabinet body one by one, then the first mounting member 4 is aligned with the corresponding first through hole, the fastening portion 41 passes through the first through hole and is embedded in the first mounting hole, and the eccentric portion 42 is placed in the first through hole, and the eccentric portion 42 and the cabinet body and the limiting portion 43 cooperate to play a limiting role to achieve the fixed connection between the outer rail 1 and the cabinet body; after each first mounting member 4 is installed in the preset first mounting hole, if the outer rail 1 is tilted or the height does not meet the expected situation, the position of the outer rail 1 can be adjusted by rotating a certain first mounting member 4 or rotating each first mounting member 4 in sequence, so that the outer rail 1 is in a horizontal state and reaches a preset height. At this time, the first mounting member 4 can be locked by the locking portion 44, which greatly reduces the risk of the eccentric portion 42 moving downward due to the gravity of the outer rail 1 or the drawer, so that the outer rail 1 is stably connected to the cabinet body.

[0056] Based on the above design, it can be seen that the installation of the outer rail 1 of the utility model does not require the use of screws, nor does it require a protruding structure to be punched out on the outer rail 1. Not only is the installation efficiency high and the installation convenience strong, but the production difficulty of the outer rail 1 will also be reduced accordingly, thereby improving the yield rate of the slide rail assembly; secondly, the outer rail 1 can be adjusted during the installation process so that the outer rail 1 is in a horizontal state and reaches a preset height, thereby improving the convenience of subsequent assembly of the inner rail 3 and the outer rail 1, and making the drawers installed on the cabinet more beautiful.

[0057] In some embodiments, at least one fastening boss 411 is provided on the side wall of the fastening portion 41. When there are multiple fastening bosses 411, the multiple fastening bosses 411 are sequentially spaced along the axial direction of the fastening portion 41. When the fastening portion 41 is embedded in the first mounting hole of the cabinet, the fastening portion 41 is in close contact with the hole wall of the first mounting hole to prevent the first mounting member 4 from being separated from the first mounting hole. The structure of the fastening boss 411 can be as follows: Figure 6-Figure 7 As shown, the longitudinal section of the fastening boss 411 is triangular. In this way, when the fastening portion 41 is knocked into the first mounting hole, the fastening boss 411 can have a tendency to retract inward, reducing the resistance between the first mounting member 4 and the wall of the first mounting hole, making the installation of the fastening portion 41 easier. When the fastening portion 41 is subjected to outward pulling force, the fastening boss 411 will have a tendency to expand outward, thereby tightly pressing against the wall of the first mounting hole, increasing the resistance between the first mounting member 4 and the wall of the first mounting hole, so that the fastening portion 41 can hardly be separated from the first mounting hole, thereby improving the connection firmness between the outer rail 1 and the cabinet.

[0058] In some embodiments, at least one first through-hole is a strip-shaped hole; when any first mounting member 4 is controlled to rotate to adjust the position of the outer rail 1, the eccentric portion 42 generates a circular motion. The use of the strip-shaped hole in conjunction with the eccentric portion 42 ensures that the cooperation between one first mounting member 4 and the outer rail 1 is not interfered with by the other first mounting member 4, thereby ensuring smooth operation of adjusting the position of the outer rail 1. Preferably, the cross-section of the eccentric portion 42 is circular, one first through-hole is a strip-shaped hole that matches the eccentric portion 42, and the other first through-hole is a circular hole that matches the eccentric portion 42; in this way, the cooperation between the eccentric portion 42 and the wall of the circular hole can limit the movement of the outer rail 1 in the front-to-back direction, thereby improving the stability of the outer rail 1 and further improving the secure connection between the drawer and the cabinet body.

[0059] In some embodiments, a stamped protrusion is provided on the first sliding surface 111 of the first fixed plate 11, and the first through hole is opened on the protrusion; in this way, the contact area between the eccentric portion 42 and the outer rail 1 can be increased, and the stability of the fit between the eccentric portion 42 and the outer rail 1 can be improved.

[0060] In some embodiments, the locking portion 44 includes at least one locking ridge 441 distributed on the side wall of the fastening portion 41. When there are multiple locking ridges 441, the multiple locking ridges 441 are sequentially spaced along the circumference of the fastening portion 41. When the fastening portion 41 is fully embedded in the first mounting hole of the cabinet, the locking ridge 441 is in close contact with the side wall of the first mounting hole to limit the rotation of the first mounting member 4. Figure 6-Figure 7 As shown, the locking portion 44 is located on the side of the fastening boss 411 close to the limiting portion 43. When installing the outer rail 1, first tap the first mounting member 4 so that the fastening portion 41 is partially placed in the first mounting hole and the locking boss is located outside the first mounting hole. At this time, the first mounting member 4 can be easily rotated so that the eccentric portion 42 acts on the outer rail 1 to achieve position adjustment of the outer rail 1. After the position adjustment of the outer rail 1 is completed, the fastening portion 41 is completely knocked into the first mounting hole so that the locking protrusion 441 is close to the hole wall of the first mounting hole, thereby limiting the rotation of the first mounting member 4 and greatly reducing the risk of displacement of the eccentric portion 42.

[0061] Furthermore, the structure of the locking ridge 441 can be as follows: Figure 6-Figure 7 As shown, the cross-section of the locking ridge 441 is triangular. In this way, when the fastening portion 41 is knocked into the first mounting hole and the first mounting member 4 is controlled to rotate in the forward direction (the forward direction can be clockwise or counterclockwise), the locking ridge 441 can produce a tendency to retract inward, reducing the resistance between the first mounting member 4 and the wall of the first mounting hole, making the forward rotation of the fastening portion 41 easier. When the fastening portion 41 is subjected to a force and tends to rotate in the reverse direction (that is, in the direction opposite to the forward direction), the locking ridge 441 will tend to expand outward, thereby tightly pressing against the wall of the first mounting hole, increasing the resistance between the first mounting member 4 and the wall of the first mounting hole, so that the fastening portion 41 can hardly rotate in the reverse direction, reducing the risk of displacement of the eccentric portion 42.

[0062] In some embodiments, the slide rail assembly also includes an embedded part 45, the embedded part 45 includes a conical portion 451, and the embedded part 45 is installed in the first mounting hole of the cabinet; the middle part of the fastening part 41 is provided with a lock mouth that cooperates with the conical portion 451, and the fastening part 41 is provided with at least one first deformation gap 46 that is opened inward from the outer wall to communicate with the lock mouth, and locking parts 44 are formed on both sides of the first deformation gap 46; when the number of the first deformation gaps 46 is multiple, the multiple first deformation gaps 46 are distributed along the circumference of the fastening part 41. When installing the outer rail 1, first install the embedded part 45 into the first mounting hole, then tap the first mounting part 4 so that the fastening part 41 is partially placed in the first mounting hole. At this time, the first mounting part 4 can be easily rotated so that the eccentric part 42 acts on the outer rail 1 to achieve the position adjustment of the outer rail 1. After the position adjustment of the outer rail 1 is completed, the fastening part 41 is completely knocked into the first mounting hole so that the conical part 451 is inserted into the lock mouth, and then the locking part 44 expands outward and presses against the wall of the first mounting hole, thereby limiting the rotation of the first mounting part 4, greatly reducing the risk of the eccentric part 42 being offset, that is, reducing the risk of the outer rail 1 being offset again.

[0063] To further explain, the locking portion 44 may also adopt other structures. It is only necessary to limit the rotation of the first mounting member 4 after the outer rail 1 completes the position adjustment to reduce the risk of the eccentric portion 42 moving downward due to the influence of the gravity of the slide rail or drawer. Other structures of the locking portion 44 are not listed one by one here.

[0064] In some embodiments, a driving portion 47 is provided on the limiting portion 43. The driving portion 47 is configured to be driven by an external tool to rotate the first mounting member 4. The provision of the driving portion 47 improves the ease of rotation and manipulation of the first mounting member 4. The driving portion 47 is generally a groove, such as a slotted, Phillips, or hexagonal slot. This structure is suitable for a slotted or Phillips screwdriver or hexagonal wrench, which are common household tools and facilitate user assembly of the slide rail assembly. Of course, the driving portion 47 may also have other structures, which are not limited here.

[0065] In some embodiments, a second deformation gap 13 is provided on the first fixed plate 11, an elastic portion 14 is formed in the middle of the second deformation gap 13, and a first through hole is formed on the elastic portion 14; in this way, the outer rail 1 can produce a certain degree of left and right movement, so that when the outer rail 1 is assembled with the inner rail 3, the outer rail 1 can better cooperate with the inner rail 3 through the movement of the outer rail 1, thereby improving the assembly convenience of the inner rail 3 and the outer rail 1.

[0066] In some embodiments, the third fixing plate 31 defines two second through holes, each of which is provided with a second mounting member 5 corresponding thereto. The second mounting member 5 is used to mount the inner rail 3 to the drawer. The structure of the second mounting member 5 is identical to that of the first mounting member 4. The coordination between the second mounting member 5 and the second mounting hole in the drawer is similar to the coordination between the first mounting member 4 and the first mounting hole in the cabinet body, and will not be further described here.

[0067] Any structure not described in detail in this embodiment may refer to existing slide rail assemblies. For example, the first sliding member 6 and the second sliding member 7 may be a conventional bead assembly structure, specifically comprising a bead body and a plurality of balls respectively secured to the bead body. The structure and operating principle of the connection between the middle rail 2 and the outer rail 1 via the first sliding member 6 and the connection between the inner rail 3 and the middle rail 2 via the second sliding member 7 may refer to the prior art. The same applies to other structures and are omitted here.

[0068] The above description is only a preferred embodiment of the present invention, and its structure is not limited to the shapes listed above. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
