Description

TECHNICAL FIELD

[0001] The utility model relates to drawer technical field, concretely relates to a drawer guide rail's front code connector of joint. BACKGROUND

[0002] The current drawer is generally composed of a panel, side plates, a back plate and a bottom plate. There are two main connection methods between the drawer and the guide rail, one of which is to use screws to fix between the bottom plate and the slide rail, 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 maintenance or replacement of parts is required. 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 maintenance time and maintenance costs. However, the existing connector structure for two-section guide rails is relatively complex, which is not conducive to improving assembly speed, especially the longitudinal adjustment structure provided on the upper part 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 guide rail bracket. SUMMARY

[0003] The present application aims to solve the problem of the complex structure of the front code connector of the existing drawer guide rail, which cannot be automatically assembled, and provides a connector with a simple structure.

[0004] To achieve the above invention purpose, the utility model takes the following technical scheme:

[0005] The front code connector of the drawer guide rail comprises a base and a locking mechanism. The rear and middle parts of the base are respectively provided with a first mounting area and a second mounting area, and the second mounting area is provided with a first rotating shaft. The locking mechanism comprises a driving member, a reset member and a locking member. The driving member is provided with a first transmission part, and the locking member is provided with a buckling part and a second transmission part. The locking member is slidably arranged on the first mounting area, the driving member is rotatably sleeved on the first rotating shaft, the reset member is used to reset the driving member, and the first transmission part of the driving member protrudes backward from the second mounting area and is connected with the second transmission part to drive the locking member to reciprocate.

[0006] Compared with the prior art, the connector of the utility model is designed to be simple, only including a base and a locking mechanism, and the connection and transmission mode between the components are simple and clear, which is conducive to reducing manufacturing cost and improving assembly speed. In addition, the space of the base is planned, and the first mounting area and the second mounting area are provided corresponding to the locking mechanism, combined with the simple shaft pin connection design, so that the components of the locking mechanism can be easily identified and assembled by automatic equipment, which can effectively improve the production efficiency and reduce the labor cost.

[0007] Furthermore, the first transmission part is a protrusion, the second transmission part is a groove, and the first transmission part is slidably connected to the second transmission part. In this solution, when the driving member rotates, the first transmission part swings synchronously to press the side wall of the groove, so that the locking member is forced to move in a straight line along the installation slot. In this solution, the first transmission part is cleverly designed in the form of a protrusion, and the second transmission part that matches it is designed as a groove. This design makes it easy to open an opening on the front side of the first installation area that is compatible with the first transmission part, so that the first transmission part can slide into the first installation area through this opening without obstacles, so as to improve the assembly efficiency of the connector. In addition, the shape design of the first transmission part and the second transmission part restricts the driven part of the locking member to prevent it from detaching from the installation slot.

[0008] Furthermore, the rear portion of the second transmission part is rectangular and its width is designed to be greater than the width of the first transmission part. The front portion of the second transmission part is shaped like a ramp, and the sidewall of the front portion near the locking portion is a ramp. In this solution, the diameter of the rear portion of the second transmission part is designed to be greater than the width of the first transmission part. This design ensures that the first transmission part has room to slide within the second transmission part after entering the second transmission part. The ramp design allows the front portion of the second transmission part to provide more room for the first transmission part to swing. When the driving member rotates, the first transmission part swings with it and presses against the sidewall of the second transmission part. The presence of the ramp makes this pressing smoother, avoiding transmission obstruction caused by insufficient space. While providing sliding and swinging space for the first transmission part, this solution avoids unstable connection between the first and second transmission parts due to the excessive diameter of the rear portion of the second transmission part. Therefore, the ramp design ensures both sufficient space and transmission stability.

[0009] Furthermore, a mounting groove is provided on the first mounting area, and the locking member is located on the first mounting area. A limiting step is provided on one side of the mounting groove, and the side of the locking member close to the buckling portion abuts against the limiting step, and the buckling portion protrudes outward from the mounting groove. The front side of the first mounting area cooperates with the first transmission part to provide an opening connected to the mounting groove, so that the first transmission part can enter the first mounting area through the opening. The limiting step of this solution can prevent the locking member from detaching from the first mounting area from the side close to the buckling portion, while the first transmission part and the second transmission part cooperate to prevent the locking member from detaching from the first mounting area from the other side. This solution ensures that the locking member will not detach from the side close to the buckling portion and will not slide out from the other side during the transmission process through the provision of the limiting step and the precise cooperation of the first transmission part and the second transmission part. There is no need to provide a limiting mechanism for the locking member outside the first mounting area or corresponding to other positions, making the structure of the connector more streamlined.

[0010] Further, the driving member further comprises a swing arm, the first rotating shaft, the first transmission part and the swing arm are in a triangular distribution on the driving member, so that when the swing arm is pressed to swing, the driving member as a whole rotates along the third shaft hole, so that the first transmission part rotates. When the swing arm is pressed to swing, due to the stability of the triangular distribution, the driving member as a whole will rotate along the third shaft hole. This rotation in turn drives the first transmission part to rotate, realizing the transmission connection with the second transmission part on the locking member. This design makes the stress of the driving member more uniform and the rotation more stable.

[0011] Further, the longitudinal adjusting mechanism further comprises a driving nut and a driving rod, the driving nut is in transmission connection with the driving rod, the driving rod and the adjusting rod are vertically arranged, the driving portion and the driving rod are connected through the setting of a bidirectional inclined rail driving structure, the driving rod can move in the third mounting area to drive the adjusting rod to displace forward and backward. Compared with the prior art, the driving rod can drive the adjusting rod to move backward and also can drive it to move forward through the setting of the bidirectional inclined rail driving structure between the driving portion and the driving rod. The adjusting mode is more flexible, and the structure is simple.

[0012] Further, the longitudinal adjusting mechanism further comprises a driving nut and a driving rod, the driving nut is in transmission connection with the driving rod, the driving rod and the adjusting rod are vertically arranged, the driving portion and the driving rod are connected through the setting of a bidirectional inclined rail driving structure, the driving rod can move in the third mounting area to drive the adjusting rod to displace forward and backward. Compared with the prior art, the driving rod can drive the adjusting rod to move backward and also can drive it to move forward through the setting of the bidirectional inclined rail driving structure between the driving portion and the driving rod. The adjusting mode is more flexible, and the structure is simple.

[0013] Further, the bidirectional inclined rail driving structure comprises a concave rail and an inclined block, the concave rail is arranged on the adjusting rod and penetrates through the left and right ends of the adjusting rod, and extends forwardly from one end close to the driving rod to the other end, the inclined block is arranged at the end of the driving rod and located in the concave rail, and the two sides of the inclined block are in sliding connection with the side walls of the concave rail. In the scheme, the inclined block and the concave rail are in sliding cooperation. When the driving nut drives the driving rod to displace to the side close to the adjusting rod, one side surface of the inclined block abuts against one side wall of the concave rail to drive it to move backward. When the driving nut drives the driving rod to reset, the inclined block abuts against the other side wall of the concave rail to drive it to move forward, thereby driving the adjusting rod to reset forward.

[0014] Further, the end surface of the abutment part of the adjusting rod is adapted to the inclined surface of the concave rail arranged in parallel therewith, so that the inclined surface and the concave rail form a convex rail, and the driving rod is adapted to the convex rail and is provided with an inclined groove. The original two-way inclined rail driving structure has realized the function of two-way adjustment, and the design of the inclined groove and the convex rail further increases the connection between the driving rod and the adjusting rod, so that the connection between the driving rod and the adjusting rod is more intuitive and simple. Through the cooperation of the sliding groove and the convex rail, the alignment and assembly of the two can be easily realized, the installation difficulty is reduced, and the transmission between the driving rod and the adjusting rod is more stable and accurate. The cooperation of the sliding groove and the convex rail can reduce friction and shaking during transmission.

[0016] Further, the central axis of the driving nut is perpendicular to the length direction of the driving rod, one end of the driving nut is provided with a helical first connecting part, and the driving rod is provided with a second connecting part.

The driving nut and the driving rod are connected in transmission through the first connecting part and the second connecting part to form a perpendicular transmission structure. When the driving nut rotates axially, the first connecting part and the second connecting part move relatively, so as to convert the rotary motion into linear motion, thereby driving the adjusting rod to move linearly along the length direction, realizing accurate longitudinal adjustment. When assembled, the longitudinal adjustment mechanism can be connected and assembled in one body through the first connecting part and the second connecting part, and is assembled to the third mounting area.

[0034] Embodiment one:

[0035] Referring to Figures 1-9As shown, the embodiment discloses a front code connector 1 of a drawer guide rail, comprising a base 2 for connecting with a drawer and a locking mechanism 3 arranged on the base 2, the rear part of the base 2 is provided with a first mounting area 21, the middle part is provided with a second mounting area 22, the first mounting area 21 is provided with a mounting sliding groove 211, the second mounting area 22 is provided with a first rotating shaft, the first rotating shaft is provided with a first shaft hole 221, the locking mechanism 3 comprises a driving piece 31, a reset piece 34 and a locking piece 32, the reset piece 34 is provided with a second shaft hole 341, the driving piece 31 is provided with a third shaft hole 311 and a first transmission part 312, the locking piece 32 is provided with a buckling part 321 and a second transmission part 322, the locking piece 32 is slidably arranged on the mounting sliding groove 211, the driving piece 31 and the reset piece 34 are arranged on the second mounting area 22, the second shaft hole 341 and the third shaft hole 311 are sleeved on the first rotating shaft, the first shaft hole is connected with a shaft nail 33 to make the driving piece 31 swing around the first rotating shaft 222, the first transmission part 312 of the driving piece 31 extends out of the second mounting area 22 and is in transmission connection with the second transmission part 322, the driving piece 31 drives the locking piece 32 to slide to the side away from the buckling part 321 by rotating, and the reset piece 34 resets the driving piece 31 after driving, so that the driving piece 31 drives the locking piece 32 to return to the initial position.

[0036] The first transmission part 312 is a protrusion, the second transmission part 322 is a groove, the front side of the first mounting area 21 is provided with an opening 214 matched with the first transmission part 312, the first transmission part 312 enters the first mounting area 21 through the opening 214 and is in sliding connection with the second transmission part 322. In the scheme, when the driving piece 31 rotates, the first transmission part swings synchronously to press the side wall of the groove, so that the locking piece 32 is forced to move linearly along the mounting sliding groove 211. In the scheme, the first transmission part 312 is designed as a protrusion, and the second transmission part 322 matched with it is designed as a groove. This design makes the front side of the first mounting area 21 be able to conveniently open the opening 214 matched with the first transmission part 312, so that the first transmission part 312 can slide into the first mounting area 21 through the opening 214 without obstacles, so as to improve the assembly efficiency of the connector 1. In addition, the shape design of the first transmission part 312 and the second transmission part 322 limits the locking piece 32 by the driving piece 31, avoiding the locking piece 32 from separating from the mounting sliding groove 211.

[0037] The rear part of the second transmission part 322 is rectangular and has a width greater than that of the first transmission part 312, and the front part of the second transmission part 322 is in the shape of a stepped slope, and the side wall near the side of the buckle part 321 is a slope. In this embodiment, the diameter of the first connecting groove is greater than the width of the first transmission part 312, which ensures that the first transmission part 312 has a sliding space in the first connecting groove after entering the second transmission part 322, and the slope design provides more swing space for the first transmission part 312. When the driving part 31 rotates, the first transmission part 312 will swing and press against the side wall of the second transmission part 322. The presence of the slope makes the pressing more smooth, avoiding the transmission being blocked due to insufficient space. This embodiment provides sliding and swing space for the first transmission part 312 while avoiding the diameter of the first connecting groove being too large, which causes unstable connection between the first transmission part 312 and the second transmission part 322. Therefore, through the design of the stepped slope, sufficient space is ensured, and the stability of the transmission is also ensured.

[0038] The mounting groove 211 is a through hole transversely penetrating the first mounting area 21, one side of the through hole is provided with a limiting step (not shown in the figure), the side of the locking part 32 near the buckle part 321 abuts against the limiting step, and the buckle part 321 protrudes outward from the through hole. The limiting step of this embodiment can prevent the locking part 32 from separating from the first mounting area 21 from the side near the buckle part 321, and the cooperation of the first transmission part 312 and the second transmission part 322 prevents the locking part 32 from separating from the first mounting area 21 from the other side. Through the setting of the limiting step and the precise cooperation of the first transmission part 312 and the second transmission part 322, it is ensured that the locking part 32 will not separate from the side near the buckle part 321, and it is also ensured that it will not slide out from the other side during transmission, so there is no need to set a limiting mechanism for the locking part 32 outside the first mounting area 21 or other positions, which makes the structure of the connector 1 more compact.

[0039] The driving part 31 further comprises a swing arm 313, and the third shaft hole 311, the first transmission part 312 and the swing arm 313 are in a triangular distribution on the driving part 31, so that when the swing arm 313 is pressed and swung, the driving part 31 as a whole rotates along the third shaft hole 311, so that the first transmission part 312 rotates. When the swing arm 313 is pressed and swung, due to the stability of the triangular distribution, the driving part 31 as a whole rotates along the third shaft hole 311. This rotation in turn drives the first transmission part 312 to rotate, realizing the transmission connection with the second transmission part 322 of the locking part 32. This design makes the force on the driving part 31 more uniform and the rotation more stable.

[0040] The first mounting area 21 is arranged on one side of the rear part of the base 2, and the other side of the rear part of the base 2 is provided with a clearance adapted to the guide rail, and the clearance is further provided with a clamping structure 24, which includes a first limiting part 241 provided with the edge of the first mounting area 21, a second limiting part 242 opposite to the first limiting part 241, and a recess formed between the first limiting part 241 and the second limiting part 242. The recess is further provided with a spring pressing part 243 opposite to the buckle part 321. After assembly, the side wall of the guide rail is clamped between the first limiting part 241 and the second limiting part 242, the buckle part 321 is buckled on the buckle hole of the side wall of the guide rail, and the spring pressing part 243 elastically presses the front end of the guide rail.

[0041] The reset member 34 is a torsion spring, the lower side of the locking member 32 is provided with a clamping groove 323 matched with the torsion spring, one end of the torsion spring presses the inner side wall of the clamping groove 323, and the other end passes through the clamping groove 323 and presses the side surface of the first limiting part 241.

[0042] The locking member 32 and the mounting sliding groove 211 are provided with a linear guide rail structure, including a directional groove 213 arranged on the inner wall of the sliding groove and a directional rail 324 arranged on the locking member 32.

[0043] Compared with the prior art, the connector 1 of the embodiment is designed simply, only including the base 2 and the locking mechanism 3, and the connection and transmission mode between the components are simple and clear, which is beneficial to reduce the manufacturing cost and improve the assembly speed. In addition, the space of the base 2 is planned, the first mounting area 21 and the second mounting area 22 are arranged corresponding to the locking mechanism 3, and the simple shaft pin 33 connection and the mounting sliding groove 211 design make the components of the locking mechanism 3 can be easily recognized and assembled by the automatic equipment, which can effectively improve the production efficiency and reduce the labor cost.

[0044] Embodiment two:

[0045] The difference between the embodiment and the above-mentioned embodiments is that the embodiment adds a longitudinal adjusting mechanism 4, the base 2 is provided with a third mounting area 23, the longitudinal adjusting mechanism 4 is arranged on the third mounting area 23, and the longitudinal adjusting mechanism 4 at least includes an adjusting rod 43, both ends of the adjusting rod 43 are configured as an adjusting part 431 and a driving part 433, the adjusting part 431 is provided with an adjusting inclined surface 432, the rear part of the third mounting area 23 is adapted to the adjusting rod 43 and is provided with a clearance passing opening 234, and the adjusting part 431 can pass through the clearance passing opening 234 and be connected with the drawer bottom and the guide rail. In the scheme, the adjusting inclined surface 432 arranged on the adjusting part 431 interacts with the contact surface of the drawer part or the guide rail, so that the height is finely adjusted. The inclination angle of the inclined surface determines the sensitivity and range of the adjustment, and in actual application, different inclination angles can be designed to adapt to different adjustment requirements. In addition, the longitudinal adjusting mechanism 4 is integrated on the mounting area, and the structure is relatively independent, which is convenient for independent installation, disassembly and maintenance.

[0046] Further, the longitudinal adjusting mechanism 4 further includes a driving nut 41 and a driving rod 42, the driving nut 41 is in transmission connection with the driving rod 42, the driving rod 42 and the adjusting rod 43 are arranged vertically, the driving part 433 and the driving rod 42 are connected through the setting of a bidirectional inclined rail driving structure 44, and the driving rod 42 can move in the third mounting area 23 to drive the adjusting rod 43 to displace forward and backward. Compared with the prior art, in the scheme, the driving part 433 and the driving rod 42 are connected through the setting of the bidirectional inclined rail driving structure 44, the driving rod 42 can drive the adjusting rod 43 to move backward and also can drive it to move forward, the adjusting mode is more flexible, and the structure is simple.

[0047] Further, the bidirectional inclined rail driving structure 44 includes a concave rail 44a and an inclined block 44b, the concave rail 44a is arranged on the adjusting rod 43 and penetrates through both ends of the adjusting rod 43, extends forward from one end close to the driving rod 42 to the other end, the inclined block 44b is arranged at the end of the driving rod 42 and located in the concave rail 44a, and both sides of the inclined block 44b are in sliding connection with the side walls of the concave rail 44a. In the scheme, the inclined block 44b is in sliding connection with the concave rail 44a, when the driving nut 41 drives the driving rod 42 to displace to the side close to the adjusting rod 43, one side surface of the inclined block 44b abuts against one side wall of the concave rail 44a and drives it to move backward, when the driving nut 41 drives the driving rod 42 to reset, the inclined block 44b abuts against the other side wall of the concave rail 44a and drives it to move forward, so as to drive the adjusting rod 43 to reset forward.

[0048] Further, the end surface of the abutment portion 433 of the adjusting rod 43 is adapted to a bevel surface parallel to the concave rail 44a, so that a convex rail 44c is formed between the bevel surface and the concave rail 44a, and the driving rod 42 is adapted to the convex rail 44c and provided with a bevel groove 44d. The original bidirectional bevel rail driving structure 44 has realized the bidirectional adjusting function, and the design of the bevel groove 44d and the convex rail 44c further increases the connection between the driving rod 42 and the adjusting rod 43, which is more intuitive and simple. The alignment and assembly of the two can be easily realized through the cooperation of the bevel groove and the convex rail 44c, which reduces the installation difficulty and makes the transmission between the driving rod 42 and the adjusting rod 43 more stable and accurate. The cooperation of the bevel groove and the convex rail 44c can reduce the friction and shaking during transmission.

[0049] Further, the third mounting area 23 is provided with a first mounting groove 231, a second mounting groove 232 and a third mounting groove 233, the first mounting groove 231 penetrates through the second mounting groove 232 and the third mounting groove 233, the driving rod 42, the driving nut 41 and the adjusting rod 43 are arranged on the first mounting groove 231, the second mounting groove 232 and the third mounting groove 233 respectively, and the end of the driving rod 42 extends from the first mounting groove 231 to the third mounting groove 233.

[0050] Further, the central axis of the driving nut 41 is perpendicular to the length direction of the driving rod 42, one end of the driving nut 41 is provided with a helical first connecting portion 411, and the driving rod 42 is provided with an arc-shaped protrusion as a second connecting portion 421. When the driving nut 41 rotates axially, the first connecting portion 411 and the second connecting portion 421 produce relative motion, so as to drive the adjusting rod 43 to move linearly along the length direction. The driving nut 41 and the driving rod 42 are connected through the first connecting portion 411 and the second connecting portion 421 to form a perpendicular transmission structure. When the driving nut 41 rotates axially, the first connecting portion 411 and the second connecting portion 421 produce relative motion, which converts the rotary motion into linear motion, so as to drive the adjusting rod 43 to move linearly along the length direction, realizing accurate longitudinal adjustment.

[0051] The transmission principle between the driving nut 41 and the driving rod 42 is as follows: when the driving nut 41 rotates axially, the first connecting part 411 will generate a rotating movement along the central axis of the driving nut 41 due to its spiral shape. Meanwhile, the second connecting part 421 is fixed on the driving rod 42, so it will not rotate with the driving nut 41. Due to the interaction between the first connecting part 411 and the second connecting part 421, the rotating movement will be converted into a linear movement on the driving rod 42 when the driving nut 41 rotates. Specifically, the spiral first connecting part 411 will push or pull the arc-shaped protrusion during rotation, so as to make the driving rod 42 move along its length direction. By adjusting the rotation angle of the driving nut 41, the linear movement distance of the driving rod 42 can be accurately controlled, so as to realize accurate longitudinal adjustment.

[0052] Further, the second connecting part 421 is arranged at intervals along the length direction of the driving rod 42. In the present scheme, when the driving rod 42 is located at the initial position, the outer end of the bolt is clamped between the two second connecting parts 421 farthest away from the adjusting rod 43 on one side of the driving rod 42, and when the driving rod 42 is displaced to the maximum stroke, the outer end of the bolt is clamped between the two second connecting parts 421 closest to the adjusting rod 43.

[0053] The transmission principle between the driving rod 42 and the adjusting rod 43 is as follows: when the driving rod 42 is located at the initial position, the outer end of the bolt is clamped between the two second connecting parts 421 farthest away from the adjusting rod 43 on one side of the driving rod 42. This means that before the driving nut 41 starts to rotate, the bolt has been stably clamped by the two second connecting parts 421. When the driving nut 41 starts to rotate axially, the spiral first connecting part 411 will generate relative movement with the second connecting part 421 on the driving rod 42. Due to the interval arrangement of the second connecting part 421, the relative movement will gradually and continuously push or pull the driving rod 42 to move along its length direction. With the movement of the driving rod 42, the outer end of the bolt will gradually move out of the initial two second connecting parts 421 and pass through the intermediate second connecting parts 421 in turn, until reaching the maximum stroke. When the driving rod 42 is displaced to the maximum stroke, the outer end of the bolt is clamped between the two second connecting parts 421 closest to the adjusting rod 43.
