Description

Technical Field

[0001] This invention relates to the field of drawer slide technology, and more particularly to an adjustable drawer slide structure and drawer cabinet. Background Technology

[0002] Currently, although drawer cabinets of the same specifications have the same external width, the internal width of each drawer cabinet varies due to the different thickness of the side panels. This results in drawer cabinets of the same specifications needing to be equipped with different specifications of drawer slides, which reduces the versatility of the drawer slide structure and increases production costs.

[0003] Furthermore, while some adjustable-width drawer slides exist, they typically only allow adjustment within a specific width range and cannot flexibly adapt to variations in the inner width of the drawer. Moreover, current adjustable-width drawer slides are difficult to switch quickly and easily from a locked state to an adjustable state, resulting in slow and inefficient drawer assembly, which in turn reduces ease of assembly and hinders user experience. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an adjustable drawer slide structure and drawer cabinet, which can improve the versatility of the slide structure.

The transmission part is located in the connection port, and the drive part is connected to the transmission part shaft through the connection port and the limiting hole.

[0009] The limiting hole is provided along the height direction of the transmission plate so that the driving part can reciprocate along the limiting hole with the axial movement of the driving shaft and drive the transmission part, thereby causing the transmission part to drive the transmission plate to reciprocate along the mounting cavity.

[0010] Preferably, the drive unit is further provided with a shaft connection end, which is located on both sides of the connection port, and the shaft connection end is connected to the shaft of the transmission unit via the connection port and the limiting hole.

[0011] Preferably, the drive unit is further provided with a connecting groove, the opening of the connecting groove facing the transmission unit, and the connecting groove communicating with the connecting port, so that the connecting groove can be fitted onto the transmission unit.

[0012] Preferably, the drive shaft is further provided with a tightening end, which passes through the mounting cavity and is exposed on the outer side wall of the fixing seat.

[0013] Preferably, the limiting post is located near the edge of the transmission plate, and the limiting post has a protrusion along its length direction, and the guide hole has a guide groove along its length direction, with the protrusion being engaged in the guide groove.

[0014] Preferably, the adjustable drawer slide structure further includes a locking plate and a locking hole through the locking plate. The locking plate is fitted onto the limiting post through the locking hole, and the mounting cavity is also provided with a through groove communicating with the guide hole. The opening of the through groove is offset from the guide hole. The locking plate passes through the opening of the through groove to the outside, and the locking plate can rotate axially around the limiting post to approach and enter the through groove and lock the limiting post.

[0015] Preferably, the inner wall of the locking hole is provided with a first protruding surface and a first flat surface that are staggered from each other along its circumference, and the outer wall of the limiting post is provided with a second protruding surface and a second flat surface that are staggered from each other along its circumference; when the locking plate rotates axially around the limiting post and approaches and enters the through groove, the first flat surface approaches and abuts against the second protruding surface, so that the locking plate clamps the limiting post through the locking hole;

[0016] The first protruding surface is close to the second flat surface, and the first protruding surface overlaps with the second flat surface.

[0017] Preferably, the mounting groove is provided with a through hole communicating with the mounting cavity, the position of the through hole corresponds to the position of the transmission part, and the width of the through hole is greater than or equal to the width of the mounting groove.

[0018] Preferably, the adjustable drawer slide structure further includes a protective cover that covers the side wall of the mounting base.

[0019] Accordingly, the present invention provides a drawer cabinet including the aforementioned adjustable drawer slide structure.

[0020] Implementing this invention has the following beneficial effects:

[0021] The mounting base of this invention has a mounting cavity, and the mounting base has a mounting groove and a clearance opening connected to the mounting cavity. The opening of the mounting groove faces opposite directions to the clearance opening, so that the lower rail seat can enter the mounting cavity through the clearance opening. The drive shaft is installed in the mounting groove and is connected to the lower rail seat via the mounting cavity. By rotating the drive shaft, the lower rail seat can be driven to reciprocate along the mounting cavity, thereby adjusting the distance between the lower rail seat and the inner wall of the drawer, thus improving the versatility of this slide rail structure. Furthermore, the lower rail seat can move along the mounting cavity and stop at any position. Compared with the previous slide rail structure that could only be adjusted within a specific width, this slide rail structure has greater adjustment flexibility.

[0022] Specifically, the lower rail seat includes a transmission plate and a connecting plate arranged at an angle to each other. The transmission plate is located inside the mounting cavity for transmission, while the connecting plate passes through the clearance opening and is located on the outside to facilitate subsequent assembly and realize the sliding function of the drawer. The transmission plate has a limiting post facing the opening of the mounting groove, and the mounting cavity has a guide hole. The limiting post passes through the guide hole to guide the movement of the transmission plate and ensure that the transmission plate drives the connecting plate to move stably in a preset direction.

[0023] Furthermore, the drive shaft is located within the mounting groove, and the drive shaft is provided with a drive part and a connection port passing through the end of the drive part. The transmission plate is provided with a transmission part and a limiting hole passing through the transmission part. The transmission part is located within the connection port. The drive part is shaft-connected to the transmission part via the connection port and the limiting hole to achieve linkage with the transmission part, enabling the drive part to drive the transmission part to reciprocate along the mounting cavity to adjust the distance between the connecting plate and the inner wall of the drawer, thereby improving the versatility of this slide rail structure.

[0024] Furthermore, to achieve the driving function, the limiting hole is set along the height direction of the transmission plate to provide moving space for the driving part, so that the driving part can move back and forth along the limiting hole with the axial movement of the driving shaft, and drive the transmission part by pushing or pulling, so that the transmission part drives the transmission plate to move back and forth along the mounting cavity. Thus, the distance between the connecting plate and the inner wall of the drawer can be adjusted simply by turning the driving shaft, making the operation convenient. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this document are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0033] The objectives, technical solutions, and advantages of this invention are now clearer. The invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that any directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to limit the scope of the invention.

[0034] Combination Figures 1 to 6 According to one embodiment of the present invention, an adjustable drawer slide structure is provided, including a lower slide seat 1, a fixed seat 2 and a drive shaft 3;

[0035] The mounting base 2 of this invention has a mounting cavity 21, and the mounting base 2 has a mounting groove 22 and a clearance opening 23 connected to the mounting cavity 21. The opening of the mounting groove 22 faces opposite directions to the clearance opening 23, so that the lower rail seat 1 enters the mounting cavity 21 through the clearance opening 23. The drive shaft 3 is installed in the mounting groove 22 and is connected to the lower rail seat 1 via the mounting cavity 21. By rotating the drive shaft 3, the lower rail seat 1 can be driven to reciprocate along the mounting cavity 21, thereby adjusting the distance between the lower rail seat 1 and the inner wall of the drawer and improving the versatility of this slide rail structure. Furthermore, the lower rail seat 1 can move along the mounting cavity 21 and stop at any position. Compared with the previous slide rail structure that could only be adjusted within a specific width, this slide rail structure has greater adjustment flexibility.

[0036] Specifically, the lower rail seat 1 includes a transmission plate 11 and a connecting plate 12 arranged at an included angle. The transmission plate 11 is located inside the mounting cavity 21 for transmission, while the connecting plate 12 passes through the clearance opening 23 and is located externally to facilitate subsequent assembly and realize the sliding function of the drawer. The transmission plate 11 has a limiting post 111 facing the opening of the mounting groove 22, and the mounting cavity 21 has a guide hole 211. The limiting post 111 passes through the guide hole 211 to guide the movement of the transmission plate 11, ensuring that the transmission plate 11 drives the connecting plate 12 to move stably in a preset direction. The guide hole 211 can be arranged along the depth direction of the mounting groove 22.

[0037] Furthermore, the drive shaft 3 is located within the mounting groove 22, and the drive shaft 3 is provided with a drive part 31 and a connection port 311 penetrating the end of the drive part 31. The transmission plate 11 is provided with a transmission part 112 and a limiting hole 113 penetrating the transmission part 112. The transmission part 112 is located within the connection port 311. The drive part 31 is axially connected to the transmission part 112 via the connection port 311 and the limiting hole 113, realizing linkage between the drive part 31 and the transmission part 112. This allows the drive part 31 to drive the transmission part 112 to reciprocate along the mounting cavity 21, thereby adjusting the distance between the connecting plate 12 and the inner wall of the drawer and improving the versatility of this slide rail structure.

[0038] Furthermore, to achieve the driving function, the limiting hole 113 is set along the height direction of the transmission plate 11 to provide moving space for the driving part 31, so that the driving part 31 can move back and forth along the limiting hole 113 with the axial movement of the driving shaft 3, and drive the transmission part 112 by pushing or pulling, so that the transmission part 112 drives the transmission plate 11 to move back and forth along the mounting cavity 21. Thus, the distance between the connecting plate 12 and the inner wall of the drawer can be adjusted simply by turning the driving shaft 3, which is convenient to operate.

[0039] In one embodiment, the drive unit 31 moves counterclockwise to push the transmission unit 112 to move forward, thereby increasing the distance between the connecting plate 12 and the inner wall of the drawer; conversely, the drive unit 31 moves clockwise to pull the transmission unit 112 to move in the opposite direction, thereby decreasing the distance between the connecting plate 12 and the inner wall of the drawer.

[0040] It should be noted that, in order to prevent the drive shaft 3 from easily detaching from the mounting groove 22, a retaining ring 24 is detachably connected in the mounting groove 22. The retaining ring 24 is fitted on the drive shaft 3 to ensure that the drive shaft 3 can rotate while being securely connected to the mounting groove 22.

[0041] Preferably, combined with Figures 1 to 5To further realize the driving function, the driving unit 31 is also provided with a shaft connecting end 312. The shaft connecting end 312 is located on both sides of the connecting port 311, and the shaft connecting end 312 is connected to the transmission unit 112 shaft through the connecting port 311 and the limiting hole 113. The driving is connected through the shaft connecting end 312, so as to facilitate the driving unit 31 to apply force to the transmission unit 112. The shaft connection between the shaft connecting end 312 and the transmission unit 112 can be realized by the shaft passing through the shaft connecting end 312, the connecting port 311 and the limiting hole 113.

[0042] More preferably, the drive unit 31 is also provided with a connecting groove 313, the opening of the connecting groove 313 facing the transmission unit 112, and the connecting groove 313 communicating with the connecting port 311, so that the connecting groove 313 can be fitted onto the transmission unit 112, so as to avoid the drive unit 31 occupying the moving space of the transmission plate 11 and ensure the movable range of the transmission plate 11.

[0043] More preferably, to further facilitate adjustment, the drive shaft 3 is also provided with a tightening end 32. The tightening end 32 passes through the mounting cavity 21 and protrudes from the outer wall of the fixing seat 2, allowing the operator to drive the drive shaft 3 to rotate axially by tightening the tightening end 32 after the fixing seat 2 is installed on the inner wall of the drawer. This achieves the function of adjusting the distance between the connecting plate 12 and the inner wall of the drawer, making operation convenient and allowing the operator to adjust according to the actual situation. The tightening end 32 may be provided with an insertion slot for inserting a screwdriver, allowing the operator to tighten the tightening end 32 with a screwdriver, further improving operational convenience.

[0044] More preferably, to further ensure the moving stability of the transmission plate 11, the limiting post 111 is close to the edge of the transmission plate 11, and the limiting post 111 is provided with a protrusion 114 along its length direction. The guide hole 211 is provided with a guide groove 212 along its length direction. The protrusion 114 is stuck in the guide groove 212 to ensure that the transmission plate 11 drives the connecting plate 12 to move stably in a preset direction, and that deflection or shaking is not likely to occur during the movement.

[0045] It should be noted that, in order to stably drive the transmission plate 11, multiple drive units 31 can be provided along the length direction of the drive shaft 3, with each drive shaft 3 spaced apart by a preset distance; correspondingly, multiple transmission units 112 are provided along the length direction of the transmission plate 11, and the position of each transmission unit 112 corresponds to the position of each drive shaft 3.

[0046] On the other hand, combining again Figures 1 to 6To make the slide rail structure more flexible in adjustment, the adjustable drawer slide rail structure also includes a locking plate 4 and a locking hole 41 passing through the locking plate 4. The locking plate 4 is fitted onto the limiting post 111 through the locking hole 41, and the mounting cavity 21 is also provided with a through groove 213 communicating with the guide hole 211. The opening of the through groove 213 is offset from the guide hole 211, so that the locking plate 4 can pass through the opening of the through groove 213 to the outside.

[0047] Specifically, as one embodiment, the present invention has two operating states, A and B. State A is the locking state. After the transmission plate 11 drives the connecting plate 12 to move to the predetermined position, the operator can rotate the locking plate 4 to make it rotate axially around the limiting post 111 and approach and enter the through groove 213 to lock the limiting post 111, thereby allowing the lower rail seat 1 to move along the mounting cavity 21 and stay at any position. State B is the unlocking state. When it is necessary to adjust the distance between the connecting plate 12 and the inner wall of the drawer, the operator only needs to rotate the locking plate 4 in the opposite direction to move it from inside the through groove 213 to the outside to achieve the unlocking function, so that the transmission plate 11 can drive the connecting plate 12 to move freely. The operation is simple and convenient, ensuring ease of assembly.

[0048] Furthermore, the inner wall of the locking hole 41 is provided with a first protruding surface 411 and a first flat surface 412 that are staggered from each other along its circumference, and the outer wall of the limiting post 111 is provided with a second protruding surface 115 and a second flat surface 116 that are staggered from each other along its circumference; when in the unlocked state, the locking plate 4 moves from inside the through groove 213 to the outside, so that the first protruding surface 411 and the second protruding surface 115 overlap, and the first flat surface 412 and the second flat surface 116 overlap, so as to release the locking function of the locking plate 4 on the limiting post 111, so that the transmission plate 11 can move freely;

[0049] When in the locked state, the locking plate 4 rotates axially around the limiting post 111 and approaches and enters the through groove 213. The first flat surface 412 approaches and abuts against the second protruding surface 115. Thus, through the cooperation of the first flat surfaces 412, the locking plate 4 clamps the limiting post 111 through the locking hole 41 to lock the transmission plate 11. The first protruding surface 411 is close to the second flat surface 116, and the first protruding surface 411 overlaps with the second flat surface 116.

[0050] Preferably, to facilitate the connection between the drive shaft 3 and the transmission plate 11, the mounting groove 22 is provided with a through hole 221 that communicates with the mounting cavity 21. The position of the through hole 221 corresponds to the position of the transmission part 112, and the width of the through hole 221 is greater than or equal to the width of the mounting groove 22, so as to provide rotation space for the drive part 31.

[0051] More preferably, the adjustable drawer slide structure also includes a protective cover 5, which covers the side wall of the fixing seat 2, so that after adjustment, the protective cover 5 can cover the tightening end 32 to provide protection.

[0052] It should be noted that, in combination Figure 7 As one embodiment, the present invention can adopt a modular slide rail, which allows the operator to first install the fixed seat 2 with the lower rail seat 1 and drive shaft 3 on the inner wall of the drawer, and then connect it with the middle rail 6, the ball bearing 7, the upper rail 8 and other structures through the connecting plate 12 to form a complete slide rail structure, thereby improving the ease of assembly.

[0053] Since the drawer cabinet of this disclosure includes the adjustable drawer slide structure as described in any of the above embodiments, the drawer cabinet of this disclosure has the technical effects brought about by the adjustable drawer slide structure as described in any of the above embodiments. Therefore, the specific technical effects of the drawer cabinet of this disclosure can be referred to the technical effects of the adjustable drawer slide structure of any of the above embodiments, and will not be repeated here.

[0054] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
