Description

TECHNICAL FIELD

[0001] The utility model relates to drawer technical field, concretely relates to two -dimensional handle connector with longitudinal adjustment function. BACKGROUND

[0002] In the current market, the structure of the drawer generally includes a panel, side plates, a back plate, and a bottom plate. In the connection technology between the drawer and the guide rail, there are mainly two kinds of mainstream methods: one is to directly fix the bottom plate and the slide rail with screws; the other is to use a connector to achieve flexible connection between the two. Compared with the traditional screw fixing method, the connector connection method has shown significant advantages in the application of drawer slide rails. It makes the drawer easier to disassemble and reassemble when repairing or replacing parts. Thanks to the modular design concept of the connector, once a component fails, the user can quickly locate the source of the problem and replace it without having to disassemble the entire slide rail system or the drawer, which greatly shortens the repair time and reduces the maintenance cost.

[0003] However, although the connector connection method has many advantages, the existing connector designed for two-section guide rails is relatively complex in structure. This complexity not only affects the improvement of assembly efficiency, especially in connectors equipped with longitudinal adjustment structures for adjusting the height of the drawer, the complexity of the structure becomes a major obstacle in the automated assembly process. These complex designs make the connector less convenient to assemble and disassemble in the process of assembling and disassembling the drawer and the guide rail bracket, limiting the further improvement of production efficiency. Therefore, it is of great significance to develop a connector with simple structure, easy to automate assembly and convenient to disassemble to improve the convenience and efficiency of the connection between the drawer and the guide rail. The current drawer is generally composed of a panel, side plates, a back plate, and a bottom plate. There are mainly two ways to connect the drawer and the guide rail, one of which is to fix the bottom plate and the slide rail with screws, and the other is to use a connector. Compared with the traditional screw connection method, the drawer slide rail connected by the connector can be easily disassembled and reassembled when it needs to be repaired or replaced. Due to the modular design of the connector, when a component fails, the faulty component can be quickly located and replaced without the need to disassemble the entire slide rail or drawer, thereby saving repair time and maintenance costs. However, the existing connector for two-section guide rails has a relatively complex structure, which is not conducive to improving assembly speed, especially the longitudinal adjustment structure provided on the connector for adjusting the height of the drawer, which has a complex structure, making it difficult to achieve automated assembly of the connector and difficult to assemble and disassemble the drawer and the guide rail bracket. SUMMARY

[0004] The purpose of the invention of the utility model is to solve the problem that the existing two-dimensional handle connector with a longitudinal adjustment function has a complex structure and cannot be assembled automatically, and to provide a connector with a simple structure.

[0005] In order to achieve the above invention objectives, the present invention adopts the following technical solutions:

[0006] A two-dimensional handle connector with a longitudinal adjustment function includes a base and a locking mechanism and a longitudinal adjustment mechanism provided on the base; the base is provided with a first mounting slot; the longitudinal adjustment mechanism includes an adjusting nut and an adjusting rod, the adjusting nut is rotatably provided on the first mounting slot, a first connecting portion is provided on one side of the adjusting nut, the first connecting portion is provided as a spiral line that gradually diffuses from the middle of the side surface of the adjusting nut to the periphery, the adjusting rod is connected to the first connecting portion through a transmission structure, and the rotation of the adjusting nut causes the transmission structure to move left and right and drives the adjusting rod to move forward and backward.

[0007] In the present invention, the axial rotation is converted into horizontal movement by adjusting the cooperation between the nut and the adjusting rod. Compared with the existing complex connector design, this solution realizes the longitudinal adjustment function through the simple transmission structure of the adjusting nut and the adjusting rod, reducing unnecessary parts and complex assembly steps.

[0008] Furthermore, the transmission structure includes a drive rod and a drive structure, wherein one end of the drive rod is provided with a second connecting portion connected to the first connecting portion, and the other end is provided with a first inclined block. The distal end of the adjustment rod is provided with a first inclined rail that is engaged with the first inclined block, and the first inclined block and the first inclined rail form a drive structure. In this embodiment, the longitudinal adjustment mechanism realizes the adjustment function by slidingly cooperating between the inclined block of the drive rod and the concave rail of the adjustment rod. When the adjustment nut drives the drive rod to move toward the adjustment rod, one side surface of the inclined block abuts against one side wall of the concave rail, driving the adjustment rod to move backward. When the adjustment nut drives the drive rod to reset, the inclined block abuts against the other side wall of the concave rail, driving it to move forward, thereby driving the adjustment rod to reset forward.

[0009] The utility model discloses, the first connecting portion and the second connecting portion drive connection form perpendicular transmission structure between adjusting nut and drive rod, when adjusting nut axial rotation, the first connecting portion and the second connecting portion produce relative motion, convert rotary motion into linear motion, thereby drive adjusting rod linear movement along its length direction, realize accurate longitudinal adjustment, when assembling, the longitudinal adjustment mechanism of the scheme can be connected through the first connecting portion and the second connecting portion and make adjusting nut and drive rod assemble in an organic whole, assemble to second installation area again, because of the modular design and easy to dismantle of longitudinal adjustment mechanism's characteristics, when some components appear the failure, the user can position and replace the failure component quickly, need not to carry out large -scale disassembly to whole slide rail system or drawer, this not only shortens the maintenance time, also reduced maintenance cost significantly.

[0010] Further, the second connecting portion is an arc-shaped protrusion, and the second connecting portion is in contact with the first connecting portion through an arc surface thereof. In the utility model, the first connecting portion and the second connecting portion drive connection form perpendicular transmission structure between adjusting nut and drive rod, when adjusting nut axial rotation, the first connecting portion and the second connecting portion produce relative motion, convert rotary motion into linear motion, thereby drive adjusting rod linear movement along its length direction, realize accurate longitudinal adjustment, when assembling, the longitudinal adjustment mechanism of the scheme can be connected through the first connecting portion and the second connecting portion and make adjusting nut and drive rod assemble in an organic whole, assemble to second installation area again, because of the modular design and easy to dismantle of longitudinal adjustment mechanism's characteristics, when some components appear the failure, the user can position and replace the failure component quickly, need not to carry out large -scale disassembly to whole slide rail system or drawer, this not only shortens the maintenance time, also reduced maintenance cost significantly.

[0011] Further, the end surface of the adjusting rod near the first inclined groove is adapted to a first inclined rail, and the first inclined rail is provided with a second inclined surface parallel to the first inclined surface, so that the second inclined surface and the first inclined rail form a second inclined rail, and the drive rod is adapted to the second inclined rail and provided with a second inclined groove. Based on the original bidirectional inclined rail driving structure that has realized the bidirectional adjustment function, the second inclined rail and the second inclined groove are further designed, so that the connection between the drive rod and the adjusting rod is more intuitive and simple, the alignment and assembly of the two can be easily realized through the cooperation of the second inclined rail and the second inclined groove, the installation difficulty is reduced, and the transmission between the drive rod and the adjusting rod is more stable and accurate, and the cooperation of the sliding groove and the convex rail can reduce friction and shaking during transmission.

[0012] Furthermore, the base is provided with a second mounting area, the second mounting area being provided with a second mounting slot, a third mounting slot, and the first mounting slot, with the first mounting slot intersecting the second mounting slot and the third mounting slot, respectively. The drive rod, adjustment nut, and adjustment rod are respectively provided in the first mounting slot, the second mounting slot, and the third mounting slot, with the distal end of the drive rod extending from the first mounting slot to the third mounting slot. In this solution, the establishment of the first, second, and third mounting slots provides precise mounting positions for each component, ensuring the stability and reliability of the entire adjustment mechanism.

[0013] Furthermore, at least three second connecting portions are spaced apart along the length of the drive rod. In this embodiment, a space is formed between two adjacent second connecting portions for the first connecting portion to pass through. When the drive rod is in its initial position, the outer end of the spiral first connecting portion is sandwiched between the two second connecting portions on the side of the drive rod furthest from the adjusting rod. When the drive rod reaches its maximum travel, its outer end is sandwiched between the two second connecting portions closest to the adjusting rod. This means that before the adjusting nut begins to rotate, the spiral is already stably held in place by these two second connecting portions. When the adjusting nut begins to rotate axially, its spiral first connecting portion generates relative motion with the second connecting portions on the drive rod. Because the second connecting portions are spaced apart, this relative motion gradually and continuously pushes or pulls the drive rod along its length. As the drive rod moves, the outer end of the spiral gradually moves out from between the first two second connecting portions and passes through the middle second connecting portion until it reaches its maximum travel. When the drive rod reaches its maximum travel, the outer end of the spiral is sandwiched between the two second connecting portions closest to the adjusting rod. This means that the driving rod has moved to the farthest position it can reach and is stably clamped by the two second connecting parts.

[0014] Furthermore, a positioning shaft is provided at one end of the adjusting nut away from the drive rod, and a positioning groove is adapted to fit the side of the first mounting slot. This solution is used for positioning during assembly. During installation, the adjusting nut and the drive rod are first assembled together and then clamped to the base. The positioning groove and the positioning shaft cooperate to achieve rapid guided positioning.

[0015] Furthermore, the longitudinal adjustment mechanism also includes a mounting cover, which is arranged on the second mounting area to limit the longitudinal adjustment mechanism from upwardly separating from the mounting area, and is provided with an adjustment opening corresponding to the adjustment nut.

[0016] Furthermore, the mounting cover and the base are connected via a snap-fit ​​structure.

[0017] Furthermore, the base is provided with a first mounting area that is approximately T-shaped, and a second mounting area that is L-shaped, with the end of the T located in a recessed position within the L. The locking mechanism is secured to the base via a pin. The mounting cover is L-shaped, with a positioning edge in the recessed position, against which the handle of the pin presses. This solution enhances the stability of the connection between the mounting cover and the base. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following further illustrates the technical solution of the present invention according to the accompanying drawings:

[0033] In the description of the present invention, it should be understood that the orientations or positional relationships indicated by “front”, “rear”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] Example 1:

[0035] See also Figure 1-10 As shown, this embodiment discloses a two-dimensional handle connector 1 with a longitudinal adjustment function, including a base 2 and a locking mechanism and a longitudinal adjustment mechanism 4 arranged on the base 2; a first mounting groove 241 is provided on the base 2; the longitudinal adjustment mechanism 4 includes an adjusting nut 41 and an adjusting rod 43, and the adjusting nut 41 is rotatably arranged on the first mounting groove 241, and a first connecting portion 411 is provided on one side of the adjusting nut 41, and the first connecting portion 411 is arranged to be a spiral line that gradually diffuses toward the periphery along the middle of the side surface of the adjusting nut 41, and the adjusting rod 43 is connected to the first connecting portion 411 through a transmission structure. The rotation of the adjusting nut 41 causes the transmission structure to move left and right and drives the adjusting rod 43 to move forward and backward.

[0036] The transmission structure includes a drive rod 42 and a drive structure. One end of the drive rod 42 is provided with a second connecting portion 421 connected to the first connecting portion 411, and the other end is provided with a first inclined block 44b. The end of the adjustment rod 43 is provided with a first inclined rail that is engaged with the first inclined block 44b. The first inclined block 44b and the first inclined rail form a drive structure. In this solution, the longitudinal adjustment mechanism 4 realizes the adjustment function by slidingly cooperating with the first inclined block 44b of the drive rod 42 and the first inclined rail of the adjustment rod 43. When the adjustment nut 41 drives the drive rod 42 to move toward the adjustment rod 43, one side of the first inclined block 44b abuts against one side wall of the first inclined rail, driving the adjustment rod 43 to move backward. When the adjustment nut 41 drives the drive rod 42 to reset, the first inclined block 44b abuts against the other side wall of the first inclined rail, driving it to move forward, thereby driving the adjustment rod 43 to reset forward.

[0037] The end surface of the adjustment rod 43 near the first bevel 44a is adapted to the first bevel and is configured as a parallel bevel, forming a second bevel 44c between the bevel and the first bevel. The drive rod 42 is adapted to the second bevel 44c and is provided with a second bevel 44d. This solution further adds the design of a second bevel 44c and a second bevel 44d to the existing bidirectional bevel drive structure 44, which already achieves bidirectional adjustment. This makes the connection between the drive rod 42 and the adjustment rod 43 more intuitive and simple. The cooperation between the second bevel 44c and the second bevel 44d allows for easy alignment and assembly of the two, reducing installation difficulty. This also makes the transmission between the drive rod 42 and the adjustment rod 43 smoother and more precise. The cooperation between the slideway and the convex rail 44c can reduce friction and shaking during transmission.

[0038] The second connecting portion 421 is an arc-shaped protrusion, and the second connecting portion 421 contacts the first connecting portion 411 through its arc surface. In the present invention, the adjusting nut 41 and the driving rod 42 are connected by the first connecting portion 411 and the second connecting portion 421 to form a vertical transmission structure. When the adjusting nut 41 rotates axially, the first connecting portion 411 and the second connecting portion 421 generate relative motion, converting the rotational motion into linear motion, thereby driving the adjusting rod 43 to move linearly along its length direction to achieve precise longitudinal adjustment. During assembly, the longitudinal adjustment mechanism 4 of this solution can be connected by the first connecting portion 411 and the second connecting portion 421 to assemble the adjusting nut 41 and the driving rod 42 into one body, and then assembled to the second mounting area 24. Due to the modular design and easy disassembly of the longitudinal adjustment mechanism 4, when a component fails, the user can quickly locate and replace the faulty component without having to disassemble the entire slide rail system or drawer on a large scale. This not only shortens the repair time, but also significantly reduces maintenance costs.

[0039] The base 2 is provided with a second mounting area 24, which is provided with a second mounting groove 242, a third mounting groove 243, and a first mounting groove 241. The first mounting groove 241 is connected to the second mounting groove 242 and the third mounting groove 243, respectively. The driving rod 42, the adjusting nut 41, and the adjusting rod 43 are respectively provided in the first mounting groove 241, the second mounting groove 242, and the third mounting groove 243, and the distal end of the driving rod 42 extends from the first mounting groove 241 to the third mounting groove 243. In this embodiment, the establishment of the first mounting groove 241, the second mounting groove 242, and the third mounting groove 243 provides precise mounting positions for each component, ensuring the stability and reliability of the entire adjustment mechanism.

[0040] At least three second connecting portions 421 are arranged at intervals along the length of the drive rod 42. In this embodiment, a space is formed between two adjacent second connecting portions 421 for the first connecting portion 411 to pass through. When the drive rod 42 is in its initial position, the outer end of the helical thread is clamped between the two second connecting portions 421 on the side of the drive rod 42 farthest from the adjustment rod 43. When the drive rod 42 is displaced to its maximum stroke, its outer end is clamped between the two second connecting portions 421 closest to the adjustment rod 43. This means that before the adjustment nut 41 begins to rotate, the helical thread is already stably clamped by the two second connecting portions 421. When the adjustment nut 41 begins to rotate axially, the first connecting portion 411 will generate relative motion with the second connecting portion 421 on the drive rod 42. Because the second connecting portions 421 are arranged at intervals, this relative motion will gradually and continuously push or pull the drive rod 42 along its length. As the drive rod 42 moves, the outer end of the spiral gradually moves out from between the first two second connecting portions 421 and passes through the middle second connecting portion 421 until it reaches its maximum travel. When the drive rod 42 reaches its maximum travel, the outer end of the spiral is sandwiched between the two second connecting portions 421 closest to the adjustment rod 43. This means that the drive rod 42 has reached its maximum reachable position and is stably held by the two second connecting portions 421.

[0041] To facilitate identification and alignment during assembly, the drive nut 41 is provided with an alignment hole 412 axially passing through its two ends, and the upper end of the drive rod 42 is provided with an alignment groove 422 passing through its two ends. When the adjustment rod 43 is in the initial position, the alignment hole 412 and the alignment groove 422 are located on the same straight line.

[0042] The adjusting nut 41 has a positioning shaft 423 on its end away from the drive rod 42, and a positioning groove 244 is provided on the side of the first mounting slot 241. This solution is used for positioning during assembly. During installation, the adjusting nut 41 and the drive rod 42 are first assembled together and then clamped to the base. The positioning groove 244 cooperates with the positioning shaft to achieve quick guidance and positioning.

[0043] The longitudinal adjustment mechanism 4 further comprises a mounting cover 45, which covers the second mounting area 24 to limit the upward disengagement of the longitudinal adjustment mechanism 4 from the second mounting area 24, and which is provided with an adjustment opening 451 corresponding to the adjustment nut 41.

[0044] The rear part of the second mounting area 2424 is provided with an empty passage 245 extending through the base 2 rearward and downward, the two ends of the adjustment rod 43 are provided with a driving part 433 and an adjustment part 431 respectively, the position of the adjustment part 431 corresponds to the empty passage 245 and is provided with an adjustment inclined surface 432. The adjustment rod 43 is connected with the driving rod 42 through the driving part 433, and moves forward and backward when the driving rod 42 moves, so as to adjust the height of the drawer through the rearward displacement of the adjustment part 431.

[0045] The mounting cover 45 and the base 2 are connected through a buckling structure.

[0046] The base 2 is provided with a first mounting area 25, which is close to a "T" shape, and the second mounting area 24 is in the shape of "L", and the end of the T shape is located in the recessed position of the L shape. The locking mechanism is fixed with the base 2 through the shaft nail 33, and the mounting cover 45 is designed in the shape of "L", and the recessed position is provided with a positioning edge, and the handle part of the shaft nail 33 is pressed on the positioning edge. The scheme has the effect of increasing the stability of the connection between the mounting cover 45 and the base 2.

[0047] In the embodiment, the adjustment nut 41 and the driving rod 42 are connected through the first connecting part 411 and the second connecting part 421 to form a vertical transmission structure. When the adjustment nut 41 rotates axially, the first connecting part 411 and the second connecting part 421 produce relative motion, converting the rotary motion into linear motion, so as to drive the adjustment rod 43 to move linearly along the length direction, realizing accurate longitudinal adjustment. When assembling, the longitudinal adjustment mechanism 4 of the utility model can be connected through the first connecting part 411 and the second connecting part 421 to make the adjustment nut 41 and the driving rod 42 assembled in one body, and then assembled to the second mounting area 24. Due to the modular design and the easy disassembly characteristics of the longitudinal adjustment mechanism 4, when a certain part fails, the user can quickly locate and replace the faulty part without the need to disassemble the entire slide rail system or the drawer. This not only shortens the maintenance time, but also significantly reduces the maintenance cost.

[0050] The first limiting part 22 comprises a first pressure bearing table 221, which is arranged on the side of the empty concave position close to the locking piece 31.

[0051] The base 2 is provided with a second limiting part 23, which is arranged on the side of the empty concave position away from the locking piece 31.

[0052] The second limiting part 23 is provided with a buckling hook 231.

[0053] The first limiting part 22 further comprises a second pressure bearing table 222, which is arranged on the side of the empty concave position connected with the first pressure bearing table 221, and the second pressure bearing table 222 is opposite to the buckling part 311 in front and back.

[0054] In order to avoid the front and back shaking of the guide rail, the second pressure bearing table 222 is provided with a elastic pressing part 223, which is used to elastically press against the front end of the guide rail.

[0055] Compared with the prior art, the connector 1 of the embodiment increases the first limiting part 22, when connected with the guide rail, the first limiting part 22 and the locking piece 31 jointly bear the pressure generated by the connection with the guide rail, effectively enhancing the stability of the connection between the drawer and the guide rail, especially providing additional support and pressure sharing mechanism for the locking piece 31, effectively reducing the pressure and wear of the locking piece 31 due to shaking or impact, thus the overall durability of the connector 1 is significantly improved. This makes the connector 1 able to maintain stable performance during long-term use, and is not easy to malfunction or damage.

[0056] Embodiment three:

[0057] Referring to Figure 5-9As shown, the difference between this embodiment and the above embodiment is that: the base 2 is provided with a first rotating shaft 251 and a fourth mounting groove 253, and the first rotating shaft 251 is provided with a first shaft hole 252, and a first pressing portion 254 is configured at the front end of the fourth mounting groove 253; the locking mechanism 3 includes a reset member and the above-mentioned locking member 31, and the locking member 31 is provided with a buckling portion 311, a second shaft hole 312 and a second pressing portion 313; the second shaft hole 312 is sleeved on the first rotating shaft 251, and the first shaft hole 252 is connected to the shaft pin 33, so that the locking member 31 can be swingably set On the base 2, the buckling portion 311 protrudes backward from the base 2, and the second pressing portion 313 extends to the inside of the fourth mounting groove 253 and is located at the rear side thereof; the reset member is arranged in the fourth mounting groove 253, and its two ends are respectively abutted against the first pressing portion 254 and the second pressing portion 313; when the locking member 31 is subjected to external force and swings, the distance between the first pressing portion 254 and the second pressing portion 313 is reduced, thereby causing the reset member to be compressed; and when the external force is released, the reset member will play its role and push the locking member 31 back to its original position.

[0058] The base 2 is further provided with a first sliding protrusion 255, which is arranged in an arc shape along the swing trajectory of the locking member 31. The fourth mounting groove 253 is located on the first sliding protrusion 255 and extends through the rear portion of the first sliding protrusion 255. To ensure a tight connection between the locking member 31 and the base 2 and prevent the first sliding protrusion 255 from interfering with the installation and use of the connector 1, a first sliding groove 314 is provided on the locking member 31 to cooperate with the first sliding protrusion 255. The front and rear ends of the first sliding groove 314 extend through the side wall of the locking member 31. The second pressing portion 313 is disposed on the first sliding groove 314, and the first sliding groove 314 and the first sliding protrusion 255 are slidably connected. In this solution, through the cooperation between the first sliding protrusion 255 and the first sliding groove 314, the locking member 31 and the docking surface of the base 2 are tightly fitted, and the reset member is stably connected between the first pressing portion 254 and the second pressing portion 313, thereby ensuring the connection stability while also improving the overall performance and reliability of the connector 1.

[0059] To simplify the structure, the first pressing portion 254 is a front end side wall of the first installation groove 241 .

[0060] In order to enhance the connection stability and guidance between the base 2 and the locking piece 31, a guide structure is arranged between the base 2 and the locking piece 31, which comprises a guide groove 261 arranged on one of the base 2 or the locking piece 31, and a guide protrusion 315 arranged on the other one correspondingly, which can be slidably embedded in the guide groove 261. In this scheme, the guide protrusion 315 not only plays a role in guiding the locking piece 31 to swing, but also effectively limits the swing range, preventing the reset piece from being compressed excessively due to excessive displacement, thereby protecting the elastic performance of the reset piece and ensuring the long-term stable operation of the connector 1

[0061] The guide groove 261 is annularly arranged with a limiting protrusion 262, which forms a connecting step with the side wall of the guide groove 261, and the lower side of the guide protrusion 315 is provided with an undercut 315b which is buckled on the limiting protrusion 262.

[0062] The guide protrusion 315 comprises two first elastic portions 315a which are oppositely arranged and have a compression space therebetween, the undercut 315b is arranged on the lower part of the first elastic portion 315a away from one side of the compression space, and the side surface of the undercut 315b is a slope.

[0063] The reset piece is a compression spring.

[0064] In this embodiment, the base 2 particularly reserves a fourth mounting groove 253 for the reset piece, so that the reset piece can be directly and conveniently mounted therein, which greatly improves the intuitiveness and efficiency of assembly and provides convenience for automatic assembly. At the same time, the locking piece 31 and the base 2 are connected through the shaft nail 33, which allows them to be independently installed and disassembled.
