Description

Technical Field

[0001] The present invention relates to the technical field of slide rails, and particularly to a slide rail structure. Background Art

[0002] Slide rails are widely used in many fields, such as daily furniture and household appliances like desks, cabinets, disinfection cabinets, dishwashers, as well as drawer-type storage devices for storage in industry. Currently, traditional drawer slide rails generally consist of an outer rail, a middle rail, and an inner rail that are sequentially fitted. The outer rail is installed on the drawer, and the inner rail is installed on the cabinet body. By means of the mutual sliding connection between the outer rail, the middle rail, and the inner rail, the drawer can be slid open and closed on the cabinet body.

[0003] In the prior art, in order to achieve a buffering effect, some slide rails are equipped with buffer springs to protect the slide rails and reduce noise generation. However, in the actual application process, such traditional slide rail structures expose the following significant defects: First, it is difficult to ensure reliable closing and locking of the drawer on drawer-type furniture and appliances that rely only on their own door pulling force or have a self-locking function, posing a relatively high safety risk; Second, the buffer springs used on the slide rails will gradually decay in their reset elastic force as the service life increases. When the drawer performs a reciprocating reset operation, due to the large load-bearing weight, the drawer is prone to slide outwards, resulting in the drawer being unable to close completely. This not only seriously affects the normal use effect of the product but also may bring potential safety hazards. Summary of the Invention

[0004] To overcome the technical problems in the prior art that the closing and locking of the drawer are unstable, and the buffer springs on the drawer slide rails cannot ensure long-term use, resulting in the drawer being prone to slide outwards, the present invention provides a slide rail structure, including a mounting base and a telescopic assembly. The mounting base has a mounting inner cavity, one end of the mounting inner cavity is open, the telescopic assembly is slidably connected to the mounting inner 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 inner cavity; the telescopic assembly includes a sliding member and an adjusting member, the adjusting member is rotatably arranged 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 at the second position moves to the first position, and the adjusting member is restricted and fixed at the first position; when the adjusting member rotates along the second rotation direction, the telescopic assembly located at the first position moves to the second position, and the adjusting member is restricted and fixed at the second position.

[0005] Further, the adjusting member includes a clamping plate, and the mounting seat is provided with a clamping groove. When the telescopic assembly at the first position moves to the second position, the clamping plate is clamped in the clamping groove; when the telescopic assembly at the second position moves to the first position, the clamping plate is separated from the clamping groove.

[0006] Further, the telescopic assembly further includes an angle member and a sliding seat. The angle member is rotatably connected to the sliding member. The sliding seat has a sliding inner cavity, and one end of the sliding inner cavity is open. One end of the sliding member provided with the angle member extends into the sliding inner cavity and is slidably connected to the sliding inner cavity. The angle member has a first rotation direction and a second rotation direction relative to the sliding member; when the angle member rotates along the second rotation direction, the adjusting member drives the sliding member to slide towards the sliding inner cavity, and the angle member drives the sliding seat to slide towards the mounting inner cavity; when the angle member rotates along the first rotation direction, the angle member drives the end of the sliding member provided with the adjusting member to move away from the sliding inner cavity.

[0007] Further, the sliding member includes a connecting rod, a transverse bar and a driving frame. The transverse bar is fixedly connected to the connecting rod, and the transverse bar and the connecting rod are movably connected to the driving frame. The driving frame has a cavity, and the connecting rod and the transverse bar are located in the cavity.

[0008] Further, the adjusting member further includes a first rotating shaft and a first movable block. The first rotating shaft is fixedly connected to the driving frame. The first movable block is rotatably arranged on the first rotating shaft and has the first rotation direction and the 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, and the transverse bar has an abutting surface. When the first movable block rotates along the first rotation direction, the first limiting surface is separated from the abutting surface; when the first movable block rotates along the second rotation direction, the first limiting surface abuts against the abutting surface.

[0009] Further, the angle member includes a second rotating shaft and a second movable block. The second rotating shaft is fixedly connected to the driving frame. The second movable block is rotatably arranged on the second rotating shaft and has the first rotation direction and the second rotation direction; the sliding seat includes a first limiting wall and a second limiting wall oppositely arranged with 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.

[0010] Furthermore, the telescopic assembly further includes a first sliding bracket, and the sliding member is slidably connected to the sliding inner cavity through the first sliding bracket.

[0011] Furthermore, the telescopic assembly further includes: a first limiting post, fixedly installed at the top of the sliding seat and on the left and right side walls of the sliding inner cavity. When the telescopic assembly at the second position moves to the first position, the top end of the first sliding bracket abuts against the first limiting post; a limiting block, fixedly installed at the bottom of the sliding seat. When the telescopic assembly at the first position moves to the second position, the sliding member abuts against the sliding seat.

[0012] Furthermore, it further includes a second sliding bracket, and the telescopic assembly is slidably connected to the installation inner cavity through the second sliding bracket.

[0013] Furthermore, the installation seat includes: a second limiting post, fixedly installed on both side walls of the installation inner cavity. When the telescopic assembly at the second position moves to the first position, the top end of the second sliding bracket abuts against the second limiting post; a fixing block, fixedly installed at one end of the installation inner cavity away from the adjusting member. When the telescopic assembly at the first position moves to the second position, the bottom end of the second sliding bracket abuts against the fixing block. Beneficial effects

[0014] The beneficial effects of adopting the technical solution of the present invention are as follows: The mounting base is provided with a mounting inner cavity. The inner edges on both sides of the mounting inner cavity are tracks. The outer edges on both sides of the telescopic assembly can move back and forth along the length direction of the inner edges on both sides of the mounting inner cavity. One end of the mounting inner cavity is open. The adjusting member of the telescopic assembly is located at this end of the mounting inner cavity, facilitating the adjustment of the adjusting member. The sliding member of the telescopic assembly can move back and forth in the extending direction of this end of the mounting inner 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, the adjusting member will abut against the sliding member, thereby driving the sliding member to move towards the mounting inner cavity until the entire telescopic assembly can be received in the mounting inner cavity (this is state two, that is, the telescopic assembly is in the second position). Then, the adjusting member is fixed in the second position. At this time, the adjusting member returns to the state before rotation, but the sliding member has already driven the entire telescopic assembly to be received in the mounting inner cavity; when the adjusting member rotates along the first rotation direction, the adjusting member disengages from the second position, the adjusting member and the sliding member disengage, the adjusting member returns to the state before rotation, the adjusting member releases the restriction on the sliding member, and the sliding member slides out of the mounting inner cavity, driving one end of the telescopic assembly to be pulled away from the mounting base (this is state one, that is, the telescopic assembly is in the first position). This structure directly drives the entire telescopic assembly to be able to stably move from the first position to the second position through the mutual cooperation of the sliding member and the adjusting member. The drawer can be locked in the closed state (that is, 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 (that is, the telescopic assembly is in the first position), with a stable structure; there is no need to install a buffer spring, avoiding the technical defect that the drawer is prone to outward sliding caused by the use of a buffer spring in the prior art.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Please refer to Figures 1 to 9, a slide rail structure, including a mounting base 1 and a telescopic component. The mounting base 1 has a mounting inner cavity 11, one end of the mounting inner cavity 11 is open, the telescopic component is slidably connected to the mounting inner cavity 11, and the telescopic component has a second position and a first position relative to the mounting base 1. The second position and the first position are located in the horizontal extension direction of the mounting inner cavity 11; the telescopic component includes a sliding member 3 and an adjusting member 4, the adjusting member 4 is rotatably arranged 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 component at the second position moves to the first position, and the adjusting member 4 is restricted and fixed at the first position; when the adjusting member 4 rotates along the second rotation direction, the telescopic component at the first position moves to the second position, and the adjusting member 4 is restricted and fixed at the second position.

[0020] In this technical solution, a mounting inner cavity 11 is provided on the mounting base 1. The inner edges on both sides of the mounting inner cavity 11 are tracks, and the outer edges on both sides of the telescopic component can move back and forth along the length direction of the inner edges on both sides of the mounting inner cavity 11. One end of the mounting inner cavity 11 is open, and the adjusting member 4 of the telescopic component is located at this end of the mounting inner cavity 11, which is convenient for adjusting the adjusting member 4. The sliding member 3 of the telescopic component can move back and forth in the extension direction of this end of the mounting inner cavity 11. The adjusting member 4 is rotatably connected to the sliding member 3 and has 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 to move towards the mounting inner cavity 11 until the entire telescopic component can be received in the mounting inner cavity 11 (this is state two, that is, the telescopic component is in the second position), and then the adjusting member 4 is fixed in the second position. At this time, the adjusting member 4 returns to the state before rotation, but the sliding member 3 has driven the entire telescopic component to be received 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 before rotation, the adjusting member 4 releases the restriction on the sliding member 3, and the sliding member 3 slides out of the mounting inner cavity 11, driving one end of the telescopic component to be pulled away from the mounting base 1 (this is state one, that is, the telescopic component is in the first position). This structure directly drives the entire telescopic component to move stably from the first position to the second position through the cooperation of the sliding member 3 and the adjusting member 4. The drawer can be locked in the closed state (that is, the telescopic component is in the second position), or the telescopic component moves from the second position to the first position, and the drawer can be locked in the open state (that is, the telescopic component is in the first position), with a stable structure; there is no need to install a buffer spring, avoiding the technical defect that the drawer is prone to outward sliding caused by using a buffer spring in the prior art.

[0021] Among them, as shown by Figure 1 and Figure 4 , the adjusting member 4 includes a clamping plate 45, and the mounting seat 1 is provided with a clamping groove 111. When the telescopic assembly at the first position moves to the second position, the clamping plate 45 is clamped in the clamping groove 111; when the telescopic assembly at the second position moves to the first position, the clamping plate 45 is separated from the clamping groove 111.

[0022] In this technical solution, when the telescopic assembly is in the second position, the telescopic assembly is received in the installation cavity 11 of the mounting seat 1. Among them, the bottom wall surface of the installation cavity 11 is provided with a clamping groove 111. The specific embodiment is shown by Figure 6 . The clamping plate 45 of the adjusting member 4 is clamped into the clamping groove 111, so that the telescopic assembly can be fixed in the second position, the telescopic assembly is not easy to pop out, the structure is stable, and the technical defect that it is difficult to ensure reliable closing and locking of the drawer in the prior art is solved, giving users a good product experience.

[0023] As shown by Figure 1 , Figure 2 and Figure 5 , the telescopic assembly further includes an angle member 5 and a sliding seat 6. The angle member 5 is rotatably connected to the sliding member 3. The sliding seat 6 has a sliding cavity 61, one end of the sliding cavity 61 is open, and one end of the sliding member 3 provided with the angle member 5 extends into the sliding cavity 61 and is slidably connected to the sliding cavity 61. The angle member 5 has a first rotation direction and a second rotation direction relative to the sliding member 3; when the angle member 5 rotates along the second rotation direction, the adjusting member 4 drives the sliding member 3 to slide towards the sliding cavity 61, and the angle member 5 drives the sliding seat 6 to slide towards the installation cavity 11; when the angle member 5 rotates along the first rotation direction, the angle member 5 drives the end of the sliding member 3 provided with the adjusting member 4 to move away from the sliding cavity 61.

[0024] In this technical solution, one end of the sliding member 3 is rotatably connected to the adjusting member 4, and the other end of the sliding member 3 is rotatably connected to the angle member 5. This end extends into the sliding inner cavity 61 of the sliding seat 6 and is slidably connected to the sliding inner cavity 61. Among them, both the angle member 5 and the adjusting member 4 have a first rotation direction and a second rotation direction relative to the sliding member 3. When the adjusting member 4 rotates along the second rotation direction, the adjusting member 4 drives the sliding member 3 to slide towards the sliding inner cavity 61. At this time, the sliding member 3 abuts against the angle member 5 and rotates synchronously along the second rotation direction, so as to be able to drive the sliding seat 6 to slide towards the installation inner 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 inner cavity 61. Only through the mutual cooperation of the sliding member 3, the adjusting member 4 and the angle member 5 can the position of the entire telescopic assembly be changed relative to the mounting seat 1, and the drawer can be reciprocated without installing a buffer spring. The structure is stable, and the sliding member 3 can always move along the extension direction of the installation inner cavity, avoiding the technical defect that the drawer is prone to outward sliding caused by using a buffer spring in the prior art.

[0025] The specific embodiment of the sliding member 3 consists of Figure 5 and Figure 6 As shown, the sliding member 3 includes a connecting rod 31, a transverse bar 32 and a driving frame 33. The transverse bar 32 is fixedly connected to the connecting rod 31. The transverse bar 32 and the connecting rod 31 are movably connected to the driving frame 33. The driving frame 33 has a cavity 331, and the connecting rod 31 and the transverse bar 32 are located in the cavity 331.

[0026] In this technical solution, the transverse bar 32 and the connecting rod 31 are integrally provided. The wall surface of the driving frame 33 is recessed downward to form a cavity 331. The transverse bar 32 and the connecting rod 31 are located in the cavity 331. The adjusting member 4 and the angle member 5 are located at the head and tail ends of the cavity 331. The transverse bar 32 abuts against the adjusting member 4, and the connecting rod 31 abuts against the angle member 5. When the adjusting member 4 and the angle member 5 rotate around the driving frame 33, the transverse bar 31 and the connecting rod 31 move in the cavity 331, driving the driving frame 33 to move back and forth in the length direction of the sliding inner cavity 61. Only through the mutual cooperation of the sliding member 3, the adjusting member 4 and the angle member 5 can the position of the entire telescopic assembly be changed relative to the mounting seat 1, and the drawer can be reciprocated without installing a buffer spring. The structure is stable, and the sliding member 3 can always move along the extension direction of the installation inner cavity, avoiding the technical defect that the drawer is prone to outward sliding caused by using a buffer spring in the prior art.

[0027] Among them, the assembly relationship between the sliding member 3 and the adjusting member 4 is shown in Figure 5 and Figure 6As shown, the adjusting member 4 further includes a first shaft 41 and a first movable block 42. The first shaft 41 is fixedly connected to the driving frame 33. The first movable block 41 is rotatably arranged on the first shaft 41 and has the first rotation direction and the second rotation direction. The first movable block 42 has a first limiting surface 43 and a bearing surface 44. The bearing surface 44 is adapted to bear the transverse bar 32. The transverse bar 32 has an abutting surface 321. When the first movable block 42 rotates along the first rotation direction, the first limiting surface 43 is separated from the abutting surface 321. When the first movable block 42 rotates along the second rotation direction, the first limiting surface 43 abuts against the abutting surface 321.

[0028] In this technical solution, the bearing surface 42 is formed by the downward depression of the first movable block 42 of the adjusting member 4, and the transverse bar 32 is inserted into the bearing 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 shaft 41 along the second rotation direction, the first limiting surface 43 abuts against the abutting surface 321, providing a thrust to the transverse bar 32. Also, 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 always abuts against the transverse bar 32, continuously pushing the transverse bar 32, applying a force to the transverse bar 32, and thus applying a thrust to the connecting rod 31. The end of the connecting rod 31 away from the transverse bar 32 always abuts against the sliding member 3 to drive the sliding member 3 to slide along the extending 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 always moves along the extending direction of the installation inner cavity, avoiding the technical defect that the drawer is prone to outward sliding caused by using a buffer spring in the prior art.

[0029] A specific embodiment of the cooperation among the angle member 5, the sliding member 3, and the adjusting member 4 is Figure 1 , Figure 5 and Figure 6 As shown, the angle member 5 includes a second shaft 51 and a second movable block 52. The second shaft 51 is fixedly connected to the driving frame 33. The second movable block 52 is rotatably arranged on the second shaft 51 and has the first rotation direction and the second rotation direction. The sliding seat 6 includes a first limiting wall 62 and a second limiting wall 63 oppositely arranged 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.

[0030] In this technical solution, the adjusting member 4 drives the connecting rod 31 to move, and the connecting rod 31 drives the angle member 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 member 3 to move, thereby driving the telescopic assembly located at 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 member 3 to move, thereby driving the telescopic assembly located at the first position to move to the second position. Only by adjusting the movement direction of the adjusting member 4 can the movement of the angle member 5 be driven, causing the sliding member 3 to generate a position, and further driving the entire telescopic assembly 4 to generate a relative displacement relative to the mounting base 1. Without installing a buffer spring, the reciprocating reset of the drawer can be achieved. The structure is stable, and the sliding member 3 always moves along the extension direction of the installation cavity 11, avoiding the technical defect that the drawer is prone to outward sliding caused by using a buffer spring in the prior art. The structure is simple and stable.

[0031] The specific embodiment of the telescopic assembly is shown by Figure 2 and Figure 3 As shown, the telescopic assembly further includes a first sliding frame 7, and the sliding member 3 is slidably connected to the sliding cavity 61 through the first sliding frame 7.

[0032] 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 the outer edges on both sides of the sliding member 3. One end of the sliding member 3 is fixedly connected to the first sliding frame 7, and 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 direction of the sliding cavity 61. The adjusting member 4 is located at one end of the sliding member 3 away from the sliding seat 6, which is convenient for the user to adjust the adjusting member 4. When the adjusting member 4 is cooperatively connected with the sliding member 3, the adjusting member 4 applies a force to the sliding member 3, causing the sliding member 3 to move, pushing the first sliding frame 7 to move along the length direction of the sliding cavity 61. Without withdrawing the force, the sliding member 3 always pushes the first sliding frame 7, and the first sliding frame 7 pushes the bottom of the sliding cavity 61, and then pushes the sliding seat 6 towards the direction of the installation cavity 11. The operation is convenient. Without installing a spring, only by pushing the drawer, the sliding member 3 can be pushed, and the sliding member 3 always moves along the extension direction of the installation cavity 11, avoiding the technical defect that the drawer is prone to outward sliding caused by using a buffer spring in the prior art. The structure is simple and stable.

[0033] Specifically, the assembly relationship between the sliding member 3 and the sliding seat 6 is shown by Figure 2 and Figure 3As shown, the telescopic assembly further includes: a first limiting post 8, fixedly installed at the top of the sliding seat 6 and on the left and right side walls of the sliding inner cavity 61. When the telescopic assembly at the second position moves to the first position, the top end of the first sliding frame 7 abuts against the first limiting post 8; a limiting block 2, fixedly installed at the bottom of the sliding seat 6. When the telescopic assembly at 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, and the connection is stable.

[0034] The first limiting post 8 in this embodiment is a bolt rod. When the sliding member 3 moves to the first position, the first sliding frame 7 abuts against the first limiting post 8. Since the first sliding frame 7 is fixedly installed at both ends of the sliding member 3, at this time, because the first sliding frame 7 is restricted in the sliding inner cavity 61 by the first limiting post 8, the sliding member 3 is restricted at the first position; and the limiting block 2 is fixedly installed at the bottom of the sliding seat 6. When the telescopic assembly at 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 continuously pushes the limiting block 2, thereby pushing the sliding seat 6 in the direction of the installation inner cavity 11. With just a gentle push, the clamping plate 45 of the adjusting member 4 is clamped into the clamping groove 111, realizing that the telescopic assembly can be fixed at the second position. In fact, at this time, the telescopic assembly has already been received in the installation inner cavity 11, and the telescopic assembly is not easy to pop out, with a stable structure, solving the technical defect in the prior art that it is difficult to ensure reliable closing and locking of the drawer, and giving users a good product experience.

[0035] And the connection relationship between the telescopic assembly and the mounting seat 1 is Figure 2 and Figure 3 As shown, the slide rail mounting structure for this drawer further includes a second sliding frame 9. The telescopic assembly is slidably connected to the installation inner cavity 11 through the second sliding frame 9, and the structure is simple.

[0036] In order to restrict the telescopic assembly from sliding out of the installation inner cavity 11, as Figure 2 and Figure 3 shown, the mounting seat 1 includes a second limiting post 12. The second limiting post 12 is fixedly installed on both side walls of the installation inner cavity 11. When the telescopic assembly at 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 assembly from flying out of the installation inner cavity 11, and the connection is stable.

[0037] The second limiting post 12 in this embodiment is a bolt rod. When the telescopic assembly moves to the first position, the second sliding bracket 9 abuts against the second limiting post 12. Since the second sliding bracket 9 is fixedly installed at both ends of the telescopic assembly, at this time, because the second sliding bracket 9 is restricted in the installation inner cavity 11 by the second limiting post 12, the telescopic assembly is restricted in the first position.

[0038] Furthermore, the mounting base 1 further includes a fixing block 13. The fixing block 13 is fixedly installed at one end of the installation inner cavity 11 away from the adjusting member 4. When the telescopic assembly located at 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 clamping plate 45 of the adjusting member 4 can rotate along the second rotation direction. The clamping plate 45 of the adjusting member 4 is clamped into it along the outer edge shape of the bottom wall surface of the installation inner cavity 11, so that the telescopic assembly can be fixed in the second position. In fact, at this time, the telescopic assembly has already been received in the installation inner cavity 11, and the telescopic assembly is not easy to pop out, with a stable structure, solving the technical defect in the prior art that it is difficult to ensure reliable closing and locking of the drawer, and giving users a good product experience.

[0039] It should be noted that the traditional slide rail structure is generally made of stainless steel, which is relatively heavy, increasing the transportation and installation costs. After the traditional slide rail structure is installed on the drawer, it increases the overall weight of the drawer, affecting the dynamic performance of the drawer during the pushing and pulling process. Therefore, in order to reduce the weight, this slide rail structure is made of aluminum. In order to compensate for the strength of the material, its overall thickness and self-weight are higher than those of ordinary stainless steel slide rails. In order to ensure smooth pushing and pulling between the components of the slide rail structure, as Figure 7 and Figure 9 shown, oil grooves 10 are specifically designed on both inner wall surfaces of the installation inner cavity 11 of the mounting base 1 and both inner wall surfaces of the sliding inner cavity 61 of the sliding seat 6 for storing lubricating oil, so that the second sliding bracket 9 can be pushed and pulled smoothly in the installation inner cavity 11, and the first sliding bracket 7 can be pushed and pulled smoothly in the sliding inner cavity 61 without jamming, giving users a good product experience.

[0040] Working process: The mounting base 1 is fixedly installed on the wall surface of the cabinet body by bolts. After the second sliding frame 9 is installed on both sides of the sliding seat 6, it is inserted into the installation cavity 11 of the mounting base 1. The adjusting member 4 is installed at the top of the sliding member 3, and the angle member 5 is installed at one end of the sliding member 3 away from the adjusting member 4. The first sliding frame 7 is installed on both sides of the sliding member 3 at this end. The adjusting member 4 and the sliding member 3 are fixedly installed on the side wall of the drawer by bolts. The first sliding frame 7 is inserted into the sliding cavity 61 of the sliding seat 6, and the sliding seat 6 is inserted into the installation cavity 11 of the mounting base 1 through the second sliding frame 9. After the drawer is pulled out, due to the gravity of the drawer itself, the sliding seat 6 is stretched. However, since the second sliding frame 9 installed on its side wall is restricted in the installation cavity 11 by the second limiting post 12, part of the sliding seat 6 is always restricted in the installation cavity 11, and the sliding member 3 continues to be stretched. However, since the first sliding frame 7 on its two side walls is limited in the sliding cavity 61 by the first limiting post 8, part of the sliding member 4 is always restricted in the installation cavity 11, realizing that the adjusting member 4 is restricted and fixed in the first position. Push the drawer, the adjusting member 4 abuts against the sliding member 3, push the sliding member 3 and the angle member 5 to rotate, the sliding member 3 abuts against the sliding seat 6 until the clamping plate 45 of the adjusting member 4 is clamped in the clamping groove 111 of the mounting base 1. After hearing the "click" sound, that is, the adjusting member 4 returns to the state before rotation, the adjusting member 4 cancels the abutment against the sliding member 3, and the angle member 5 cancels the abutment against the sliding seat 6. The telescopic assembly is stored in the installation cavity 11 of the mounting base 1.
