Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, specifically to a detachable slide rail. Background Technology

[0002] In many fields such as furniture manufacturing, industrial machinery, and automation equipment, detachable slide rails are key components for realizing the relative sliding and separation of parts, and their performance directly affects the stability, safety, and ease of use of the equipment. Existing detachable slide rails generally face a technical bottleneck in their design, making it difficult to balance operational stability with ease of disassembly. To prevent accidental detachment due to vibration, external impact, or load changes during operation, traditional products often employ complex mechanical locking structures, such as multiple latches, bolt fastening, or interlocking locking devices. While these structures can improve connection reliability to some extent, disassembling the slide rail (for equipment maintenance, component replacement, or space adjustment) requires the use of specialized tools to unlock each lock individually. This cumbersome process not only consumes significant time but also carries the risk of damage to the locking structure due to improper operation. Therefore, this invention proposes a detachable slide rail to address these issues. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects of the existing slide rails, which are easy to detach and difficult to disassemble, and thus provide a detachable slide rail.

[0004] To solve the above problems, this utility model provides a detachable slide rail, which includes: A first slide rail, on which a second slide rail is slidably disposed, and a first limiting mechanism is detachably connected to one end of the first slide rail; The third slide rail is slidably mounted on the second slide rail. The first slide rail is provided with a second limiting mechanism away from the first limiting mechanism. The second limiting mechanism is used for the detachable connection between the second slide rail and the first slide rail, and the third slide rail is detachably connected to the second slide rail.

[0005] Preferably, the bottom of the first slide rail is provided with a first sliding part, and the second slide rail is provided with a second sliding part adapted to the first sliding part. The first slide rail and the second slide rail are slidably connected through the first sliding part and the second sliding part. The top two sides of the first slide rail are respectively provided with third sliding parts, and the top sides of the second slide rail are located inside the third sliding parts and are slidably connected to the third sliding parts.

The limiting blocks and the limiting holes are detachably connected, and the limiting blocks extend from the bottom of the first slide rail to the top and abut against one end of the second slide rail.

[0007] Preferably, a plurality of movable holes are evenly provided on both sides of the second slide rail along the length direction, and a ball is provided in each of the movable holes. The ball extends from the outside of the second slide rail to the inside of the second slide rail, and the ball abuts against the edge of the movable hole located outside the second slide rail.

[0008] Preferably, the second limiting mechanism includes: a pair of disassembly and assembly parts, the pair of disassembly and assembly parts being disposed at one end of the first slide rail away from the first limiting mechanism, the pair of disassembly and assembly parts being slidably connected to the first slide rail and the third slide rail; and a fourth sliding part being disposed near the first sliding part of each pair of disassembly and assembly parts, the pair of disassembly and assembly parts being slidably connected to the first slide rail through the fourth sliding part respectively; Each of the pair of disassembly / assembly components is provided with a fifth sliding part near the third slide rail, and the two sides of the third slide rail are respectively slidably connected to the fifth sliding part of the pair of disassembly / assembly components.

[0009] Preferably, the second limiting mechanism further includes: a limiting member and a fixing member, the second slide rail and the pair of disassembly and assembly members are provided with a first disassembly and assembly hole and a second disassembly and assembly hole with the same shape as the limiting member projected on the bottom plane of the second slide rail, and the limiting member is slidably connected through the first disassembly and assembly hole and the second disassembly and assembly hole; The fixing member is disposed at the bottom of the third slide rail, and the fixing member is disposed at the end of the third slide rail near the first limiting mechanism; the third slide rail slides away from the first limiting mechanism relative to the first slide rail until the fixing member abuts against the limiting member.

[0010] The detachable slide rail provided by this utility model has the following beneficial effects: 1. This utility model features a second slide rail located inside a first slide rail, with the two slide rails slidably connected. A first limiting mechanism is detachably connected to one end of the first slide rail. When installed, this mechanism prevents the second slide rail from detaching from one end of the first slide rail; when disassembled, it allows the second slide rail to be detached from the first slide rail. A third slide rail is slidably connected to the second slide rail. A second limiting mechanism located at the other end of the first slide rail prevents the second slide rail from detaching from the first slide rail, and also prevents the third slide rail from detaching from the second slide rail, thus preventing detachment. When disassembly is required, removing the second limiting mechanism allows for easy assembly and disassembly of the first and second slide rails, as well as the second and third slide rails. 2. This utility model also features a detachable connection between a limiting block and a limiting hole. It can be installed when limiting is required and disassembled when the second slide rail needs to be removed, thus enabling the second slide rail to slide out of the first slide rail from this end. 3. This utility model also allows the third slide rail, which is fitted with a fixing member, to be further disengaged from the second slide rail when the limiting member is installed in the first and second disassembly holes. By binding the fixing member after the limiting member is installed, the limiting is achieved. When the limiting member is disengaged, the third and second slide rails can be disengaged from the end of the first slide rail where the first limiting mechanism is installed.

[0013] like Figure 1-4 As shown, this utility model provides a detachable slide rail, which includes: A first slide rail 1, a second slide rail 2 is slidably disposed on the first slide rail 1, and a first limiting mechanism is detachably connected to one end of the first slide rail 1; The third slide rail 3 is slidably mounted on the second slide rail 2. The first slide rail 1 is provided with a second limiting mechanism away from the first limiting mechanism. The second limiting mechanism is used for the detachable connection between the second slide rail 2 and the first slide rail 1, and the detachable connection between the third slide rail 3 and the second slide rail 2. Figure 1-4As shown, a detachable slide rail has a first slide rail 1 as a mounting support, a second slide rail 2 located inside the first slide rail 1 and slidably connected to the first slide rail 1, and a first limiting mechanism detachably connected to one end of the first slide rail 1. When installed, the first limiting mechanism prevents the second slide rail 2 from detaching from the first slide rail 1; when disassembled, the second slide rail 2 can be detached from the first slide rail 1. A third slide rail 3 is slidably connected to the second slide rail 2. A second limiting mechanism located at the other end of the first slide rail 1 prevents the second slide rail 2 from detaching from the first slide rail 1, and also prevents the third slide rail 3 from detaching from the second slide rail 2, thus preventing detachment. When disassembly is required, the first slide rail 1 and the second slide rail 2, and the second slide rail 2 and the third slide rail 3 can be disassembled by removing the second limiting mechanism, thus simplifying disassembly and assembly. The first slide rail 1, the second slide rail 2, and the third slide rail 3 are respectively provided with corresponding mounting holes for connection to external points. For example, the first slide rail 1 and the third slide rail 3 can be installed on a drawer and a table respectively, realizing the extension and retraction of the drawer relative to the table.

[0014] In some embodiments, the bottom of the first slide rail 1 is provided with a first sliding part 4, and the second slide rail 2 is provided with a second sliding part 5 adapted to the first sliding part 4. The first slide rail 1 and the second slide rail 2 are slidably connected through the first sliding part 4 and the second sliding part 5. The top two sides of the first slide rail 1 are respectively provided with third sliding parts 6, and the top sides of the second slide rail 2 are located inside the third sliding parts 6 and are slidably connected to the third sliding parts 6. Figure 1-4 As shown, the cross-sectional shapes of the first sliding part 4 and the second sliding part 5 can be trapezoidal, T-shaped, or triangular. By increasing the contact area, the friction surface is improved. At the same time, the first sliding part 4 and the second sliding part 5 are slidably connected to each other, which plays a guiding role in the process. When the second slide rail 2 slides relative to the first slide rail 1, the third sliding part 6 of the first slide rail 1 serves as another contact surface. The third sliding part 6 is slidably connected to the top of the second slide rail 2, which further improves the sliding effect of the first slide rail 1 and the second slide rail 2 and prevents them from separating.

[0015] In some embodiments, the first limiting mechanism includes: a pair of limiting blocks 7, and a pair of limiting holes 8 adapted to the limiting blocks 7 are provided on one end edge of the first sliding part 4. The limiting blocks 7 and the limiting holes 8 are detachably connected, and the limiting blocks 7 extend from the bottom to the top of the first slide rail 1 and abut against one end of the second slide rail 2. Figure 1-4 As shown, the limiting block 7 and the limiting hole 8 are detachably connected, either by snap-fit ​​or by plug-in. They are installed when limiting is required and disassembled when the second slide rail 2 needs to be removed, thus allowing the second slide rail 2 to slide out of the first slide rail 1 from this end.

[0016] In some embodiments, a plurality of movable holes 9 are evenly provided along the length direction on opposite sides of the second slide rail 2. A ball bearing 10 is disposed within each movable hole 9, extending from the outside of the second slide rail 2 to the inside, and abutting against the edge of the movable hole 9 located outside the second slide rail 2. Figure 1-4 As shown, the second slide rail 2 has movable holes 9 on both sides. The ball bearing 10 in the movable hole 9 abuts between the outer side of the movable hole 9 and the inner side of the first slide rail 1. The end of the ball bearing 10 located on the inner side of the second slide rail 2 can slide and connect with the outer side of the third slide rail 3. The setting of the ball bearing 10 can improve the flexibility of the sliding between the third slide rail 3 and the second slide rail 2, making the sliding of the two smoother.

[0017] In some embodiments, the second limiting mechanism includes: a pair of detachable components 11, the pair of detachable components 11 being disposed at the end of the first slide rail 1 away from the first limiting mechanism, and the pair of detachable components 11 being slidably connected to the first slide rail 1 and the third slide rail 3; a fourth sliding portion 12 being disposed near the first sliding portion 4 for each pair of detachable components 11, and the pair of detachable components 11 being slidably connected to the first slide rail 1 through the fourth sliding portion 12; and a fifth sliding portion 13 being disposed near the third slide rail 3 for each pair of detachable components 11, and the third slide rail 3 being slidably connected to the fifth sliding portion 13 of the pair of detachable components 11 on both sides. Figure 1-4 As shown, the second limiting mechanism is installed at the other end of the first slide rail 1 relative to the first limiting mechanism. The second slide rail 2 slides away from the first limiting mechanism relative to the first slide rail 1. The third slide rail 3 slides in the same direction as the second slide rail 2. When a pair of detachable parts 11 are installed on the first slide rail 1, they can restrict the second slide rail 2 and the third slide rail 3 to prevent them from detaching from the first slide rail 1 and the second slide rail 2. The fourth sliding part 12 adapts to the first sliding part 4 of the first slide rail 1, so that the detachable part 11 is attached to the first sliding part 4 of the first slide rail 1, and the detachable part 11 can be assembled onto the first slide rail 1. The fifth sliding part 13 acts on the sliding connection between the detachable part 11 and the third slide rail 3, so that the third slide rail 3 and the fifth sliding part 13 extend away from the first limiting mechanism when sliding.

[0018] In some embodiments, the second limiting mechanism further includes: a limiting member 14 and a fixing member 15. The second slide rail 2 and a pair of detachable members 11 are provided with a first detachable hole 16 and a second detachable hole 17, which have the same shape as the limiting member 14 projected onto the bottom plane of the second slide rail 2. The limiting member 14 is detachably connected by slidingly passing through the first detachable hole 16 and the second detachable hole 17. The fixing member 15 is disposed at the bottom of the third slide rail 3, and at one end of the third slide rail 3 near the first limiting mechanism. The third slide rail 3 slides away from the first limiting mechanism relative to the first slide rail 1 until the fixing member 15 abuts against the limiting member 14. Figure 1-4 As shown, the limiting member 14 is adapted to the first disassembly hole 16 and the second disassembly hole 17. The connection can be in the form of snap-fit ​​or plug-in. The connection effect can be enhanced by rubber gaskets to prevent easy separation. When the limiting member 14 is installed in the first disassembly hole 16 and the second disassembly hole 17, it can restrict the third slide rail 3, which is equipped with the fixing member 15, from further separating from the second slide rail 2. The connection between the fixing member 15 and the third slide rail 3 can be in the form of bolt connection, snap-fit, or adhesive. By binding the fixing member 15 after the limiting member 14 is installed, the limiting member is restricted. When it is separated, the third slide rail 3 and the second slide rail 2 can be separated from the end of the first slide rail 1 where the first limiting mechanism is installed.
