Description

Technical Field

[0001] This utility model relates to the technical field of guiding mechanisms, specifically a pull-out synchronous guiding mechanism with adjustable function. Background Technology

[0002] Pull-out guide mechanisms are used for drawers or similar pull-out guide devices and are applicable to furniture, filing cabinets, kitchen cabinets, bathroom cabinets, electromechanical cabinets, heavy-duty refrigerators, etc.

[0003] The existing pull-out guide mechanism has an upper rail, a lower rail, and a middle rail. The lower rail is fitted onto the lower part of the middle rail and a support plane is installed thereon. The upper rail is fitted onto the upper part of the middle rail and a support plane is installed thereon.

[0004] However, the pull-out guide mechanism described above has the following shortcomings in practical applications:

[0005] 1) In the existing pull-out guide mechanism, the upper rail and the middle rail do not operate synchronously during opening and closing, resulting in poor sliding of the guide mechanism, poor transmission stability, and even jamming, which seriously affects the normal use of the product.

[0006] 2) During the opening and closing process, the middle rail of the existing pull-out guide mechanism will sway left and right and collide with the upper and lower rails, which will generate a lot of noise, reduce the user experience, and easily damage the product, thus reducing its service life.

[0007] 3) If a belt-type synchronous running mechanism is added to the existing pull-out guide mechanism, it will become fatigued and loosen over time, resulting in poor stability and reduced product lifespan. Summary of the Invention

The middle rail is equipped with a synchronous running device for synchronous operation between the rails. The synchronous running device includes a fixing assembly, a front guide wheel, a rear guide wheel, and a transmission component. The front and rear guide wheels are respectively installed at the front and rear portions of the middle rail. The front and rear ends of the transmission component are respectively wound around the front and rear guide wheels. The upper and lower rails are each equipped with a fixing assembly for positioning and connecting with the transmission component.

[0010] The fixing assembly is equipped with an adjustment mechanism for adjusting the tension of the transmission component. The adjustment mechanism includes a positioning component, a movable component, an adjustment control component, and an adjustment connecting component. The positioning component is fixedly connected to one end of the transmission component and installed in the fixing assembly. The other end of the transmission component is fixedly connected to the movable component. The movable component is movably connected to the fixing assembly and has a distance between it and the positioning component. The adjustment control component is connected to the adjustment connecting component and abuts against the movable component. The adjustment control component can rotate while driving the adjustment connecting component to move, thereby pushing the movable component to move and adjusting the distance between the movable component and the positioning component.

[0011] Based on the above optimization, the adjustment mechanism further includes an adjustment locking member to prevent the moving part from loosening. The adjustment locking member is rotatably connected to the adjustment connector and abuts against or separates from the adjustment control member while rotating.

[0012] Based on the above optimization, the adjusting connector is configured as a hollow bolt through which the transmission component passes so that the other connecting end of the transmission component is fixedly connected to the movable component. One end of the hollow bolt abuts against the movable component, and the other end of the hollow bolt is threadedly connected to the adjusting control component.

[0013] Based on the above optimization, the fixing component group includes an upper fixing component and a lower fixing component, the transmission component includes a front transmission line and a rear transmission line, the upper fixing component and the lower fixing component are respectively installed on the upper rail body and the lower rail body, the upper fixing component and the lower fixing component are respectively equipped with an upper fixing sleeve and a lower fixing sleeve, the upper fixing sleeve and the lower fixing sleeve are respectively equipped with a positioning component and a movable component, the front transmission line winds around the front guide wheel and its two connecting ends are respectively connected to the positioning component of the upper fixing sleeve and the movable component of the lower fixing sleeve, the rear transmission line winds around the rear guide wheel and its two connecting ends are respectively connected to the movable component of the upper fixing sleeve and the positioning component of the lower fixing sleeve.

[0014] Based on the above optimization, the upper fixing component is integrally formed with an upper mounting position for disassembling and assembling the upper fixing sleeve, and the lower fixing component is integrally formed with a lower mounting position for disassembling and assembling the lower fixing sleeve.

[0017] Based on the above optimization, both the front drive line and the rear drive line are made of steel wire rope.

[0018] Based on the above optimization, both the front guide wheel and the rear guide wheel are configured as transmission grooved wheels that rotate on one side of the central rail body.

[0027] The present invention will now be further described with reference to the accompanying drawings.

[0028] According to the appendix Figures 1 to 5As shown, the pull-out synchronous guide mechanism with adjustable function of this utility model includes an upper rail body 1, a lower rail body 2, and a middle rail body 3 movably supported between the upper rail body 1 and the lower rail body 2. The middle rail body 3 is equipped with a synchronous running device for synchronous operation between the rail bodies. The synchronous running device includes a fixing assembly, a front guide wheel 4, a rear guide wheel 5, and a transmission component 6. The front guide wheel 4 and the rear guide wheel 5 are respectively installed at the front and rear parts of the middle rail body 3. The front and rear ends of the transmission component 6 are respectively wound around the front guide wheel 4 and the rear guide wheel 5. The upper rail body 1 and the lower rail body 2 are each equipped with a fixing assembly for positioning and connecting with the transmission component 6.

[0029] By adding a synchronous operation device, the structure of the device's fixed component group, front guide wheel 4, rear guide wheel 5, and transmission component 6 is simplified, space is reduced, and product volume is decreased. During opening and closing, the middle rail 3 is pulled outward or pushed inward, which can drive the upper rail 1 to operate synchronously, so that the guide mechanism opens and closes in sequence, improving synchronization performance and enhancing transmission stability.

[0030] Furthermore, the fixing assembly is equipped with an adjustment mechanism 7 for adjusting the tension of the transmission component 6. The adjustment mechanism 7 includes a positioning component 71, a movable component 72, an adjustment control component 73, and an adjustment connector. The positioning component 71 is fixedly connected to one end of the transmission component 6 and installed in the fixing assembly. The other end of the transmission component 6 is fixedly connected to the movable component 72. The movable component 72 is movably connected to the fixing assembly and has a distance between it and the positioning component 71. The adjustment control component 73 is connected to the adjustment connector 74, and the adjustment connector 74 abuts against the movable component 72. The adjustment control component 73 can rotate while driving the adjustment connector 74 to move, thereby pushing the movable component 72 to move and adjusting the distance between the movable component 72 and the positioning component 71.

[0031] During assembly, the adjusting control component 73 of the rotary adjusting mechanism 7 controls the movement of the adjusting connecting component 74 to push the movable component 72, thereby adjusting the distance between the movable component 72 and the positioning component 71, and thus adjusting the tension of the transmission component 6. This method is convenient to operate, greatly reduces shaking, prevents the transmission component 6 from loosening, improves operational synchronization performance, and ensures the quality of the product.

[0032] Reference Figures 1 to 5 As shown, in further detail, the adjustment mechanism 7 also includes an adjustment locking member 75 for preventing the movable member 72 from loosening. The adjustment locking member 75 is rotatably connected to the adjustment connector 74 and abuts against or separates from the adjustment control member 73 while rotating.

[0033] After the transmission component 6 is adjusted, rotate the adjusting locking component 75 to lock it onto the adjusting connector 74 and simultaneously abut against the adjusting control component 73. This effectively prevents the adjusting control component 73 from loosening, ensures the tension of the transmission component 6, and ensures the synchronous operation of the guiding mechanism.

[0034] Reference Figures 1 to 5 As shown, in further detail, the adjusting connector 74 is configured as a hollow bolt through which the transmission member 6 passes so that the other connecting end of the transmission member 6 is fixedly connected to the movable member 72. One end of the hollow bolt abuts against the movable member 72, and the other end of the hollow bolt is threadedly connected to the adjusting control member 73.

[0035] The hollow bolt of this structure allows the connecting end of the transmission component 6 to pass through the adjusting control component 73 and the hollow bolt, and be fixedly connected to the movable component 72. The structure is simple and easy to operate.

[0036] Reference Figures 1 to 5 As shown, further detailed, the fixing component group includes an upper fixing component 8 and a lower fixing component 9, and the transmission component 6 includes a front transmission line 61 and a rear transmission line 62. The upper fixing component 8 and the lower fixing component 9 are respectively installed on the upper rail body 1 and the lower rail body 2, and the upper fixing component 8 and the lower fixing component 9 are respectively equipped with an upper fixing sleeve 10 and a lower fixing sleeve 11. The upper fixing sleeve 10 and the lower fixing sleeve 11 are respectively equipped with a positioning component 71 and a movable component 72. The front transmission line 61 winds around the front guide wheel 4, and its two connecting ends are respectively connected to the positioning component 71 of the upper fixing sleeve 10 and the movable component 72 of the lower fixing sleeve 11. The rear transmission line 62 winds around the rear guide wheel 5, and its two connecting ends are respectively connected to the movable component 72 of the upper fixing sleeve 10 and the positioning component 71 of the lower fixing sleeve 11.

[0037] The combination of the upper fixing member 8, the lower fixing member 9, and the front transmission line 61 and the rear transmission line 62 of the fastener assembly using this structure allows the transmission member 6 to be positioned and connected to the fastener assembly. The segmented assembly is simple in structure and allows for targeted adjustment of the tension of the transmission member 6, improving operational synchronization and ensuring the quality of product use.

[0038] In addition, the upper fixing member 8 is integrally formed with an upper mounting position 81 for disassembling and assembling the upper fixing sleeve 10, and the lower fixing member 9 is integrally formed with a lower mounting position 91 for disassembling and assembling the lower fixing sleeve 11.

[0039] The upper mounting position 81 and the lower mounting position 91 facilitate assembly, disassembly, maintenance, and replacement, ensuring the quality of product use.

[0040] Furthermore, the upper fixing member 8 has upper limit support positions 82 at both ends to support the front transmission line 61 and the rear transmission line 62 at the same horizontal level, and the upper fixing sleeve 10 and the adjusting control member 73 are respectively located between the upper limit support positions 82 and the upper limit support positions 82. The lower fixing member 9 has lower limit support positions 92 at both ends to support the front transmission line 61 and the rear transmission line 62 at the same horizontal level, and the lower fixing sleeve 11 and the adjusting control member 73 are respectively located between the lower limit support positions 92 and the lower limit support positions 92.

[0041] The structure of the upper limit support position 82 and the lower limit support position 92 ensures that the corresponding connection ends of the front drive line 61 and the lower drive line are in a synchronous horizontal position, ensuring the stability of the transmission connection and reducing shaking.

[0042] Both the front drive line 61 and the rear drive line 62 are steel wire ropes. Both the front guide wheel 4 and the rear guide wheel 5 are drive grooved wheels that rotate on one side of the central rail body 3.

[0043] The front and rear transmission lines 62 and the front guide wheel 4 and rear guide wheel 5 of this structure reduce user fatigue, lower the frequency of shaking, improve transmission stability, and extend the service life of the product.

[0044] The above specific embodiments are only specific implementations of the present utility model with better effects. All structures that are the same as or equivalent to the pull-out synchronous guide mechanism with adjustment function of the present utility model are within the protection scope of the present utility model.
