Description

Technical Field

[0001] This invention relates to the technical field of slide rails, and in particular to a slide rail structure. Background Technology

[0002] Drawer slides have wide applications in many fields, such as everyday furniture and appliances like desks, cabinets, disinfection cabinets, and dishwashers, as well as drawer-type storage devices used in industry. Currently, traditional drawer slides generally consist of an outer rail, a middle rail, and an inner rail installed sequentially. The outer rail is installed in the drawer, and the inner rail is installed in the cabinet. The drawer can be opened and closed by sliding between the outer rail, middle rail, and inner rail.

[0003] In existing technologies, some slide rails are equipped with buffer springs to achieve a cushioning effect, thereby protecting the slide rail and reducing noise generation. However, in practical applications, this type of traditional slide rail structure has revealed the following significant drawbacks:

[0004] Firstly, in drawer-type furniture and appliances that rely solely on their own pulling force or have self-locking functions, it is difficult to ensure that the drawers can reliably close and lock, which poses a high security risk.

[0005] Secondly, the springs used in the drawer slides gradually weaken in their restoring elasticity over time. When the drawer is retracted, due to the heavy load, it may slide outwards, preventing it from closing completely. This not only seriously affects the normal use of the product but may also pose a potential safety hazard. Summary of the Invention

[0006] To overcome the technical problems of unstable drawer closure and locking in existing technologies, and the inability of the buffer springs on the drawer slide rails to guarantee that the drawer will easily slide outward after long-term use, this invention provides a slide rail structure, including a mounting base and a telescopic assembly. The mounting base has a mounting cavity, one end of which is open. The telescopic assembly is slidably connected to the mounting cavity. The telescopic assembly has a second position and a first position relative to the mounting base, and the second position and the first position are located in the horizontal extension direction of the mounting cavity. The telescopic assembly includes a sliding member and an adjusting member. The adjusting member is rotatably disposed on the sliding member and has a first rotation direction and a second rotation direction relative to the sliding member. When the adjusting member rotates along the first rotation direction, the telescopic assembly located in the second position moves to the first position, and the adjusting member is fixed in the first position. When the adjusting member rotates along the second rotation direction, the telescopic assembly located in the first position moves to the second position, and the adjusting member is fixed in the second position.

[0007] Furthermore, the adjusting component includes a snap-fit ​​plate, and the mounting base has a snap-fit ​​groove. When the telescopic component located in the first position moves to the second position, the snap-fit ​​plate snaps into the snap-fit ​​groove; when the telescopic component located in the second position moves to the first position, the snap-fit ​​plate separates from the snap-fit ​​groove.

[0008] Furthermore, the telescopic assembly also includes an angled member and a sliding seat. The angled member is rotatably connected to the sliding member. The sliding seat has a sliding cavity, one end of which is open. The end of the sliding member on which the angled member is disposed extends into the sliding cavity and is slidably connected to it. The angled member has a first rotation direction and a second rotation direction relative to the sliding member. When the angled member rotates along the second rotation direction, the adjusting member drives the sliding member to slide toward the sliding cavity, and the angled member drives the sliding seat to slide toward the mounting cavity. When the angled member rotates along the first rotation direction, it drives the end of the sliding member on which the adjusting member is disposed to move away from the sliding cavity.

[0009] Furthermore, the sliding member includes a connecting rod, a transverse bar, and a drive frame. The transverse bar is fixedly connected to the connecting rod, and the transverse bar and the connecting rod are movably connected to the drive frame. The drive frame has a cavity, and the connecting rod and the transverse bar are located in the cavity.

[0010] Furthermore, the adjusting component also includes a first rotating shaft and a first movable block. The first rotating shaft is fixedly connected to the drive frame. The first movable block is rotatably disposed on the first rotating shaft and has a first rotation direction and a second rotation direction. The first movable block has a first limiting surface and a receiving surface. The receiving surface is adapted to receive the transverse bar. The transverse bar has an abutment surface. When the first movable block rotates along the first rotation direction, the first limiting surface separates from the abutment surface. When the first movable block rotates along the second rotation direction, the first limiting surface abuts against the abutment surface.

[0011] Furthermore, the included member includes a second rotating shaft and a second movable block. The second rotating shaft is fixedly connected to the drive frame, and the second movable block is rotatably disposed on the second rotating shaft and has a first rotation direction and a second rotation direction. The sliding seat includes a first limiting wall and a second limiting wall disposed opposite to the first limiting wall. The second movable block has a second limiting surface and a third limiting surface. When the adjusting member drives the second movable block to rotate along the first rotation direction, the second limiting surface abuts against the first limiting wall. When the adjusting member drives the second movable block to rotate along the second rotation direction, the third limiting surface abuts against the second limiting wall.

[0012] Furthermore, the telescopic assembly also includes a first sliding frame, and the sliding member is slidably connected to the sliding inner cavity via the first sliding frame.

[0013] Furthermore, the telescopic assembly further includes: a first limiting post, fixedly installed at the top of the sliding seat and located on the left and right side walls of the sliding cavity, wherein when the telescopic assembly in the second position moves to the first position, the top of the first sliding frame abuts against the first limiting post; and a limiting block, fixedly installed at the bottom of the sliding seat, wherein when the telescopic assembly in the first position moves to the second position, the sliding member abuts against the sliding seat.

[0014] Furthermore, it also includes a second sliding bracket, through which the telescopic assembly is slidably connected to the mounting cavity.

[0015] Furthermore, the mounting base includes: a second limiting post, fixedly installed on both sides of the mounting cavity, wherein when the telescopic component in the second position moves to the first position, the top end of the second sliding frame abuts against the second limiting post; and a fixing block, fixedly installed at the end of the mounting cavity away from the adjusting member, wherein when the telescopic component in the first position moves to the second position, the bottom end of the second sliding frame abuts against the fixing block. Beneficial effects

[0016] The beneficial effects of adopting the technical solution of this invention are as follows:

[0017] The mounting base has a mounting cavity with its inner edges forming tracks. The outer edges of the telescopic assembly can reciprocate along the length of the inner edges of the mounting cavity. One end of the mounting cavity is open, and the adjusting member of the telescopic assembly is located at this end for easy adjustment. The sliding member of the telescopic assembly can reciprocate along the extension direction of this end of the mounting cavity. The adjusting member and the sliding member are rotatably connected and have a first rotation direction and a second rotation direction. When the adjusting member rotates along the second rotation direction, it abuts against the sliding member, thereby driving the sliding member towards the mounting cavity. The slider moves the telescopic assembly until it is fully retracted into the mounting cavity (state two, i.e., the telescopic assembly is in the second position). Then, the adjusting member is fixed in the second position. At this point, the adjusting member returns to its state before rotation, but the sliding member has already driven the entire telescopic assembly to be retracted into the mounting cavity. When the adjusting member rotates along the first rotation direction, it disengages from the second position and from the sliding member, returning to its state before rotation. The adjusting member releases its restriction on the sliding member, which slides out of the mounting cavity, pulling one end of the telescopic assembly away from the mounting base (state one, i.e., the telescopic assembly is in the first position). This structure directly drives the entire telescopic assembly to move stably from the first position to the second position through the cooperation of the sliding member and the adjusting member. The drawer can be locked in the closed state (i.e., the telescopic assembly is in the second position), or the telescopic assembly can move from the second position to the first position, locking the drawer in the open state (i.e., the telescopic assembly is in the first position). The structure is stable; no buffer spring is needed, avoiding the technical defect of existing technologies where the drawer easily slides outward due to the use of buffer springs.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] Please refer to Figures 1 to 9A slide rail structure includes a mounting base 1 and a telescopic assembly. The mounting base 1 has a mounting cavity 11, one end of which is open. The telescopic assembly is slidably connected to the mounting cavity 11. The telescopic assembly has a second position and a first position relative to the mounting base 1, the second position and the first position being located in the horizontal extension direction of the mounting cavity 11. The telescopic assembly includes a sliding member 3 and an adjusting member 4. The adjusting member 4 is rotatably disposed on the sliding member 3 and has a first rotation direction and a second rotation direction relative to the sliding member 3. When the adjusting member 4 rotates along the first rotation direction, the telescopic assembly located in the second position moves to the first position, and the adjusting member 4 is fixed in the first position. When the adjusting member 4 rotates along the second rotation direction, the telescopic assembly located in the first position moves to the second position, and the adjusting member 4 is fixed in the second position.

[0032] In this technical solution, the mounting base 1 has a mounting cavity 11. The inner edges of the mounting cavity 11 on both sides are tracks. The outer edges of the telescopic assembly on both sides can move back and forth along the length direction of the inner edges of the mounting cavity 11. One end of the mounting cavity 11 is open. The adjusting member 4 of the telescopic assembly is located at this end of the mounting cavity 11, which facilitates the adjustment of the adjusting member 4. The sliding member 3 of the telescopic assembly can move back and forth in the extension direction of this end of the mounting cavity 11. The adjusting member 4 and the sliding member 3 are rotatably connected and have a first rotation direction and a second rotation direction. When the adjusting member 4 rotates along the second rotation direction, the adjusting member 4 will abut against the sliding member 3, thereby driving the sliding member 3 towards the mounting cavity 11. The inner cavity 11 moves in the direction until the entire telescopic assembly can be housed in the mounting inner cavity 11 (this is state two, i.e., the telescopic assembly is in the second position). Then, the adjusting member 4 is fixed in the second position. At this time, the adjusting member 4 returns to the state when it has not rotated, but the sliding member 3 has already driven the entire telescopic assembly to be housed in the mounting inner cavity 11. When the adjusting member 4 rotates along the first rotation direction, the adjusting member 4 disengages from the second position, the adjusting member 4 disengages from the sliding member 3, the adjusting member 4 returns to the state when it has not rotated, the adjusting member 4 releases the restriction on the sliding member 3, the sliding member 3 slides out of the mounting inner cavity 11, and drives one end of the telescopic assembly to be pulled away from the mounting base 1 (this is state one, i.e., the telescopic assembly is in the first position). The structure directly drives the entire telescopic assembly to move stably from the first position to the second position through the cooperation of the slider 3 and the adjuster 4. The drawer can be locked in the closed state (i.e., the telescopic assembly is in the second position), or the telescopic assembly moves from the second position to the first position and the drawer can be locked in the open state (i.e., the telescopic assembly is in the first position). The structure is stable; there is no need to install a buffer spring, which avoids the technical defect of the prior art that the drawer is prone to sliding outward due to the use of a buffer spring.

[0033] Among them, by Figure 1 and Figure 4 As shown, the adjusting component 4 includes a snap-fit ​​plate 45, and the mounting base 1 has a snap-fit ​​groove 111. When the telescopic component located in the first position moves to the second position, the snap-fit ​​plate 45 snaps into the snap-fit ​​groove 111; when the telescopic component located in the second position moves to the first position, the snap-fit ​​plate 45 separates from the snap-fit ​​groove 111.

[0034] In this technical solution, when the telescopic component is in the second position, it is housed within the mounting cavity 11 of the mounting base 1. The bottom wall of the mounting cavity 11 has a snap-fit ​​groove 111. A specific embodiment is described below. Figure 6 As shown, the snap-fit ​​plate 45 of the adjusting component 4 snaps into the snap-fit ​​groove 111, so that the telescopic component can be fixed in the second position. The telescopic component is not easy to pop out, the structure is stable, and it solves the technical defect of the prior art that it is difficult to ensure that the drawer can achieve reliable closing and locking, giving users a good product experience.

[0035] Depend on Figure 1 , Figure 2 and Figure 5 As shown, the telescopic assembly further includes an angled member 5 and a sliding seat 6. The angled member 5 is rotatably connected to the sliding member 3. The sliding seat 6 has a sliding inner cavity 61, one end of which is open. The end of the sliding member 3 with the angled member 5 extends into the sliding inner cavity 61 and is slidably connected to it. The angled member 5 has a first rotation direction and a second rotation direction relative to the sliding member 3. When the angled member 5 rotates along the second rotation direction, the adjusting member 4 drives the sliding member 3 to slide toward the sliding inner cavity 61, and the angled member 5 drives the sliding seat 6 to slide toward the mounting inner cavity 11. When the angled member 5 rotates along the first rotation direction, the angled member 5 drives the end of the sliding member 3 with the adjusting member 4 to move away from the sliding inner cavity 61.

[0036] In this technical solution, one end of the slider 3 is rotatably connected to the adjusting member 4, and the other end of the slider 3 is rotatably connected to the angle member 5. This end extends into the sliding cavity 61 of the sliding seat 6 and is slidably connected to the sliding cavity 61. Both the angle member 5 and the adjusting member 4 have a first rotation direction and a second rotation direction relative to the slider 3. When the adjusting member 4 rotates along the second rotation direction, it drives the slider 3 to slide towards the sliding cavity 61. At this time, the slider 3 abuts against the angle member 5 and rotates synchronously along the second rotation direction, thereby driving the sliding seat 6. Slide towards the mounting cavity 11; when the adjusting member 4 releases the restriction on the sliding member 3, the angle member 5 rotates along the first rotation direction, and the angle member 5 drives the sliding member 3 to slide out of the sliding cavity 61. The entire telescopic assembly can change its position relative to the mounting base 1 by only the cooperation of the sliding member 3, the adjusting member 4 and the angle member 5. The drawer can return to its original position without the need for a buffer spring. The structure is stable, and the sliding member 3 can move along the extension direction of the mounting cavity. This avoids the technical defect of the prior art where the drawer is easy to slide outward due to the use of a buffer spring.

[0037] The specific embodiments of the slider 3 are as follows: Figure 5 and Figure 6 As shown, the sliding member 3 includes a connecting rod 31, a transverse bar 32, and a drive frame 33. The transverse bar 32 is fixedly connected to the connecting rod 31, and the transverse bar 32 and the connecting rod 31 are movably connected to the drive frame 33. The drive frame 33 has a cavity 331, and the connecting rod 31 and the transverse bar 32 are located in the cavity 331.

[0038] In this technical solution, the horizontal bar 32 and the connecting rod 31 are integrally set. The wall of the drive frame 33 is recessed downward to form a cavity 331. The horizontal bar 32 and the connecting rod 31 are located in the cavity 331. The adjusting member 4 and the angled member 5 are located at the beginning and end of the cavity 331. The horizontal bar 32 abuts against the adjusting member 4, and the connecting rod 31 abuts against the angled member 5. When the adjusting member 4 and the angled member 5 rotate around the drive frame 33, the horizontal bar 31 and the connecting rod 31 move in the cavity 331, driving the drive frame 33 to move back and forth in the length direction of the sliding inner cavity 61. The entire telescopic assembly can change its position relative to the mounting base 1 by the cooperation of the sliding member 3, the adjusting member 4 and the angled member 5. The drawer can return to its original position without the need for a buffer spring. The structure is stable. The sliding member 3 can move continuously along the extension direction of the mounting inner cavity, avoiding the technical defect of the prior art where the drawer is prone to sliding outward due to the use of a buffer spring.

[0039] The assembly relationship between the sliding member 3 and the adjusting member 4 is as follows: Figure 5 and Figure 6As shown, the adjusting member 4 further includes a first rotating shaft 41 and a first movable block 42. The first rotating shaft 41 is fixedly connected to the drive frame 33. The first movable block 42 is rotatably disposed on the first rotating shaft 41 and has a first rotation direction and a second rotation direction. The first movable block 42 has a first limiting surface 43 and a receiving surface 44. The receiving surface 44 is adapted to receive the transverse bar 32. The transverse bar 32 has an abutment surface 321. When the first movable block 42 rotates along the first rotation direction, the first limiting surface 43 separates from the abutment surface 321. When the first movable block 42 rotates along the second rotation direction, the first limiting surface 43 abuts against the abutment surface 321.

[0040] In this technical solution, the first movable block 42 of the adjusting member 4 is recessed downward to form a receiving surface 42, and the transverse bar 32 is inserted in the receiving surface 42. At this time, the abutting surface 321 of the transverse bar 32 faces the first limiting surface 43 of the first movable block 42. When the first movable block 42 rotates around the first axis 41 in the second rotation direction, the first limiting surface 43 abuts against the abutting surface 321, providing a thrust to the transverse bar 32. Since the connecting rod 31 is fixedly connected to the transverse bar 32, when the adjusting member 4 rotates, the first movable block 42 of the adjusting member 4... The moving block 42 continuously abuts against the horizontal bar 32, continuously pushing the horizontal bar 32 and applying force to the horizontal bar 32, thereby providing a pushing force to the connecting rod 31. The end of the connecting rod 31 away from the horizontal bar 32 continuously abuts against the sliding member 3 so as to drive the sliding member 3 to slide along the extension direction of the sliding inner cavity 61. The drawer can be closed without installing a buffer spring, the structure is stable, and the sliding member 3 continuously moves along the extension direction of the mounting inner cavity, avoiding the technical defect of the prior art that the drawer is prone to sliding outward due to the use of a buffer spring.

[0041] A specific embodiment of the cooperation between the angle member 5, the sliding member 3, and the adjusting member 4 is described below. Figure 1 , Figure 5 and Figure 6 As shown, the included member 5 includes a second rotating shaft 51 and a second movable block 52. The second rotating shaft 51 is fixedly connected to the drive frame 33. The second movable block 52 is rotatably disposed on the second rotating shaft 51 and has a first rotation direction and a second rotation direction. The sliding seat 6 includes a first limiting wall 62 and a second limiting wall 63 disposed opposite to the first limiting wall 62. The second movable block 52 has a second limiting surface 53 and a third limiting surface 54. When the adjusting member 4 drives the second movable block 52 to rotate along the first rotation direction, the second limiting surface 53 abuts against the first limiting wall 62. When the adjusting member 4 drives the second movable block 52 to rotate along the second rotation direction, the third limiting surface 54 abuts against the second limiting wall 63.

[0042] In this technical solution, the adjusting component 4 drives the connecting rod 31 to move, and the connecting rod 31 drives the angled component 5 to move. When the second movable block 52 rotates along the first rotation direction, the second limiting surface 53 abuts against the first limiting wall 62. At this time, the second movable block 52 drives the entire sliding component 3 to move, thereby driving the telescopic assembly located in the second position to move to the first position. When the second movable block 52 rotates along the second rotation direction, the third limiting surface 54 abuts against the second limiting wall 63. At this time, the second movable block 52 drives the entire sliding component 3 to move, thereby driving the telescopic assembly located in the first position to move to the second position. Only the movement direction of the adjusting component 4 needs to be adjusted to drive the movement of the angled component 5, thereby driving the sliding component 3 to generate a position, and then driving the entire telescopic assembly 4 to generate a relative displacement relative to the mounting base 1. The drawer can be returned to its original position without the need to install a buffer spring. The structure is stable. The sliding component 3 always moves along the extension direction of the mounting cavity 11, avoiding the technical defect of the prior art where the drawer is easy to slide outward due to the use of a buffer spring. The structure is simple and stable.

[0043] Specific embodiments of the telescopic component are provided by Figure 2 and Figure 3 As shown, the telescopic assembly also includes a first sliding frame 7, and the sliding member 3 is slidably connected to the sliding inner cavity 61 through the first sliding frame 7.

[0044] In this embodiment, the telescopic assembly includes a first sliding frame 7, a sliding seat 6, and a sliding member 3. The first sliding frame 7 is installed on both outer edges of the sliding member 3. One end of the sliding member 3 is fixedly connected to the first sliding frame 7. The first sliding frame 7 is located in the sliding cavity 61. The length of the first sliding frame 7 is less than that of the sliding cavity 61, and the first sliding frame 7 can move back and forth along the length of the sliding cavity 61. The adjusting member 4 is located at the end of the sliding member 3 away from the sliding seat 6, facilitating user adjustment. When the adjusting member 4 and the sliding member 3 are connected in cooperation, the adjustment... The force applied by component 4 to the sliding component 3 causes the sliding component 3 to move, pushing the first sliding bracket 7 to move along the length of the sliding inner cavity 61. The force does not dissipate, and the sliding component 3 continues to push the first sliding bracket 7, which in turn pushes the bottom of the sliding inner cavity 61, thereby pushing the sliding seat 6 to move towards the mounting inner cavity 11. The operation is convenient, and no spring needs to be installed. The sliding component 3 can be pushed by the force of pushing the drawer, and the sliding component 3 will continue to move along the extension direction of the mounting inner cavity 11. This avoids the technical defects of the prior art that use buffer springs, which cause the drawer to slide outward easily. The structure is simple and stable.

[0045] Specifically, the assembly relationship between the sliding member 3 and the sliding seat 6 is determined by... Figure 2 and Figure 3As shown, the telescopic assembly further includes: a first limiting post 8, which is fixedly installed on the top of the sliding seat 6 and located on the left and right side walls of the sliding inner cavity 61. When the telescopic assembly in the second position moves to the first position, the top of the first sliding frame 7 abuts against the first limiting post 8; and a limiting block 2, which is fixedly installed on the bottom of the sliding seat 6. When the telescopic assembly in the first position moves to the second position, the sliding member 3 abuts against the sliding seat 6, restricting the sliding member 3 from flying out of the sliding inner cavity 61, thus ensuring a stable connection.

[0046] In this embodiment, the first limiting post 8 is a bolt rod. When the sliding member 3 moves to the first position, the first sliding bracket 7 abuts against the first limiting post 8. Since the first sliding bracket 7 is fixedly installed at both ends of the sliding member 3, the sliding member 3 is restricted to the first position because the first sliding bracket 7 is restricted in the sliding inner cavity 61 by the first limiting post 8. The limiting block 2 is fixedly installed at the bottom end of the sliding seat 6. When the telescopic component located in the first position moves to the second position, the sliding member 3 abuts against the sliding seat 6. At this time, the sliding member 3 pushes the limiting block 2, thereby pushing the sliding seat 6 to move towards the mounting inner cavity 11. With just a gentle push, the snap plate 45 of the adjusting member 4 snaps into the snap groove 111, so that the telescopic component can be fixed in the second position. In fact, the telescopic component is already stored in the mounting inner cavity 11 at this time. The telescopic component is not easy to pop out, the structure is stable, and it solves the technical defect of the prior art that it is difficult to ensure that the drawer can achieve reliable closing and locking, giving users a good product experience.

[0047] The connection between the telescopic component and the mounting base 1 is... Figure 2 and Figure 3 As shown, the drawer slide mounting structure also includes a second sliding bracket 9, and the telescopic component is slidably connected to the mounting cavity 11 through the second sliding bracket 9, which is a simple structure.

[0048] To prevent the telescopic component from sliding out of the mounting cavity 11, by Figure 2 and Figure 3 As shown, the mounting base 1 includes a second limiting post 12, which is fixedly installed on both sides of the mounting cavity 11. When the telescopic component located in the second position moves to the first position, the top end of the second sliding frame 9 abuts against the second limiting post 12, restricting the telescopic component from flying out of the mounting cavity 11, and the connection is stable.

[0049] In this embodiment, the second limiting post 12 is a bolt rod. When the telescopic assembly moves to the first position, the second sliding frame 9 abuts against the second limiting post 12. Since the second sliding frame 9 is fixedly installed at both ends of the telescopic assembly, the telescopic assembly is restricted to the first position because the second sliding frame 9 is restricted in the installation cavity 11 by the second limiting post 12.

[0050] Furthermore, the mounting base 1 also includes a fixing block 13, which is fixedly installed at the end of the mounting cavity 11 away from the adjusting member 4. When the telescopic component in the first position moves to the second position, the bottom end of the second sliding bracket 9 abuts against the fixing block 13. At this time, with just a gentle push, the locking plate 45 of the adjusting member 4 can rotate along the second rotation direction. The locking plate 45 of the adjusting member 4 is engaged with the outer edge of the bottom wall of the mounting cavity 11, so that the telescopic component can be fixed in the second position. In fact, the telescopic component is already stored in the mounting cavity 11 at this time. The telescopic component is not easy to pop out, the structure is stable, and it solves the technical defect of the prior art that it is difficult to ensure that the drawer can reliably close and lock, giving users a good product experience.

[0051] It should be noted that traditional drawer slides are generally made of stainless steel, which is relatively heavy, increasing transportation and installation costs. Traditional slides, installed behind the drawer, also increase the drawer's overall weight and affect its dynamic performance during opening and closing. Therefore, to reduce weight, this drawer slide is made of aluminum. To compensate for the material's strength, its overall thickness and weight are greater than typical stainless steel slides. Furthermore, to ensure smooth opening and closing of the slide components, [the following is a separate, unrelated sentence:] ... Figure 7 and Figure 9 As shown, oil grooves 10 are specially designed on both sides of the inner wall of the mounting cavity 11 of the mounting base 1 and both sides of the inner wall of the sliding cavity 61 of the sliding base 6 to store lubricating oil. The second sliding bracket 9 can be pushed and pulled smoothly in the mounting cavity 11, and the first sliding bracket 7 can be pushed and pulled smoothly in the sliding cavity 61 without jamming, giving users a good product experience.

[0052] Working process: Mounting base 1 is fixedly installed on the wall of the cabinet with bolts. The second sliding bracket 9 is installed on both sides of the sliding base 6 and inserted into the mounting cavity 11 of mounting base 1. Adjusting component 4 is installed on the top of the sliding component 3. Angle component 5 is installed on the end of the sliding component 3 away from the adjusting component 4. The first sliding bracket 7 is installed on both sides of the sliding component 3 at this end. The adjusting component 4 and the sliding component 3 are fixedly installed on the side wall of the drawer with bolts. The first sliding bracket 7 is inserted into the sliding cavity 61 of the sliding base 6. The sliding base 6 is inserted into the mounting cavity 11 of mounting base 1 through the second sliding bracket 9. After the drawer is pulled out, the sliding base 6 is stretched due to the weight of the drawer itself. However, because the second sliding bracket 9 installed on its side wall is restricted in the mounting cavity 11 by the second limiting post 12, Therefore, the portion of the sliding seat 6 is always confined within the mounting cavity 11, while the sliding member 3 continues to be elongated. However, because the first sliding frame 7 on both sides of its side walls is limited by the first limiting post 8 within the sliding cavity 61, the portion of the sliding member 4 is always confined within the mounting cavity 11, thus fixing the adjusting member 4 in the first position. Pushing the drawer causes the adjusting member 4 to abut against the sliding member 3, pushing the sliding member 3 and the angled member 5 to rotate. The sliding member 3 abuts against the sliding seat 6 until the snap plate 45 of the adjusting member 4 snaps into the snap groove 111 of the mounting seat 1. After hearing a "click" sound, the adjusting member 4 returns to its unrotated state, the adjusting member 4 releases its abutment against the sliding member 3, the angled member 5 releases its abutment against the sliding seat 6, and the telescopic assembly is stored in the mounting cavity 11 of the mounting seat 1.
