Description

Technical Field

[0002] Bidirectional damping buffers are used to slow down the closing speed of the sliding body in a sliding system, thereby reducing the impact and noise of the system and achieving buffering and shock absorption. Currently, bidirectional damping buffers are generally installed pre-mounted onto the track; that is, the buffer is slid into the track from the end before being installed, and then the track is mounted to the wall. However, this pre-mounted method makes adjustment of the buffer inconvenient. Once the buffer is installed on the track, it is difficult to adjust its components, resulting in poor installation and usage flexibility.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

Detailed Implementation

[0027] This utility model provides a bidirectional damping buffer. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] In the description of this utility model, it should be understood that the terms "middle," "inner side," "outer side," etc., indicate the orientation or positional relationship of this utility model based on the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0029] Please see Figures 1 to 8This utility model provides a bidirectional damping buffer, including a mounting frame 1. The mounting frame 1 has an upward-opening mounting groove 11 along its length. A bidirectional damping component 2 is disposed within the mounting groove 11, and the bidirectional damping component 2 is slidably connected to the mounting groove 11. The bidirectional damping component 2 enables the damping movement of the bidirectional damping buffer. When the bidirectional damping component 2 touches a stop within the track of the sliding system, the bidirectional damping component 2 will perform a damped linear movement within the mounting groove 11, simultaneously driving the linked sliding body to perform a damped linear movement, thereby preventing a hard collision between the sliding body and the sliding system, achieving a buffering and shock-absorbing effect. A disassembly / assembly base 3 is provided at one end of frame 1. Two sets of first guide wheel assemblies 4 are provided on the disassembly / assembly base 3, and the two sets of first guide wheel assemblies 4 are respectively snap-fitted to the disassembly / assembly base 3. The guide portion of the bidirectional damping buffer is set as a split structure to achieve post-installation between the bidirectional damping buffer and the sliding system. Traditional bidirectional damping buffers typically have a single-piece guide portion, which is large in size and can only be installed from the end inlet of the sliding system's track, not from the opening of the track's sliding surface. In this application, the guide portion is a split structure, consisting of the disassembly / assembly base 3 and two sets of first guide wheel assemblies 4. During installation, the disassembly / assembly base 3 is pre-installed on the mounting frame 1, and then... A set of first guide wheel assemblies 4 are snapped onto the mounting frame 1. Then, the mounting frame 1, the disassembly / removal seat 3, and the first guide wheel assemblies 4 mounted thereon are placed into the track of the sliding system. This can be done by tilting the wheel in. Finally, another first guide wheel assembly 4 is inserted into the disassembly / removal seat 3 through the opening in the track sliding surface until the first guide wheel assembly 4 is snapped onto the mounting frame 1, completing the overall installation. This split structure effectively reduces the difficulty for installers in installing the bidirectional damping buffer and improves the installation flexibility of the bidirectional damping buffer. A guide wheel seat assembly 5 is provided at the other end of the mounting frame 1, and a second guide wheel assembly 6 is provided on the guide wheel seat assembly 5. The second guide wheel assembly 6 is detachably connected to the guide wheel seat assembly 5. Similarly, the guide portion at the other end of the mounting frame 1 is also set as a split structure, which consists of the guide wheel seat assembly 5 and the second guide wheel assembly 6. The guide wheel seat assembly 5 is pre-installed on the mounting frame 1. During installation, the guide wheel seat assembly 5 is inserted obliquely into the track of the sliding system along with the mounting frame 1. After the guide wheel seat assembly 5 is in contact with one side of the track, the second guide wheel assembly 6 is inserted into the track from the opening of the track sliding surface, and the connection between the second guide wheel assembly 6 and the guide wheel seat assembly 5 is completed. This split structure effectively reduces the difficulty for installers to install the bidirectional damping buffer and improves the installation flexibility of the bidirectional damping buffer.

[0030] In practical use, the bidirectional damping component 2 achieves the damping motion of the bidirectional damping buffer, effectively preventing hard collisions between the sliding body and the sliding system, thus achieving buffering and shock absorption effects. The guide section of the bidirectional damping buffer is designed as a split structure, including a disassembly base 3, two sets of first guide wheel assemblies 4, a guide wheel seat assembly 5, and a second guide wheel assembly 6. This split structure allows the bidirectional damping buffer to be installed later and inserted into the sliding system's track by tilting, effectively reducing installation difficulty and improving installation flexibility. The split structure also allows the bidirectional damping buffer to be installed individually from the opening of the sliding surface of the track, rather than being inserted as a whole from the end of the sliding system's track, further improving installation convenience and flexibility.

[0031] like Figures 1 to 8 As shown, further, one end of the disassembly base 3 is connected to the mounting groove 11, and the other end of the disassembly base 3 is provided with a disassembly groove 31. At least one first snap-fit ​​groove 32 is provided on each side of the disassembly groove 31. A first locking member 33 is threadedly connected to the end of the disassembly base 3 near the disassembly groove 31, and the free end of the first locking member 33 extends into the disassembly groove 31. Both sets of first guide wheel assemblies 4 are disposed within the disassembly groove 31, and both sets of first guide wheel assemblies 4 are provided with snap-fit ​​posts 42 that cooperate with the first snap-fit ​​groove 32. The free end of the first locking member 33 abuts against one end of each of the two sets of first guide wheel assemblies 4. The disassembly base 3 provides mounting positions for the two first guide wheel assemblies 4 by providing the disassembly groove 31. During installation, the first guide wheel assembly 4 is connected to the first snap-fit ​​slots 32 on both sides of the disassembly and assembly slot 31 via snap-fit ​​pins 42. This snap-fit ​​connection reduces the installation difficulty between the first guide wheel assembly 4 and the disassembly and assembly base 3. At the same time, after the two first guide wheel assemblies 4 are snapped together, the two can be fixed in the disassembly and assembly slot 31 using the first locking member 33. By turning the first locking member 33, the free end of the first locking member 33 extends into the disassembly and assembly slot 31, so that the end of the free end of the first locking member 33 abuts against the end faces of the two first guide wheel assemblies 4, thereby fixing the two first guide wheel assemblies 4 in the disassembly and assembly slot 31 simultaneously, thus completing the installation between the first guide wheel assembly 4 and the disassembly and assembly base 3. The above structure facilitates the installation personnel to disassemble and adjust the bidirectional damping buffer after installation.

[0032] In this embodiment, the top of the first snap-fit ​​groove 32 is provided with an opening, which facilitates the snap-fit ​​post 42 to be snapped into the first snap-fit ​​groove 32 from top to bottom.

[0033] like Figures 1 to 8As shown, the first guide wheel assembly 4 further includes a guide wheel mounting bracket 41, the snap-fit ​​post 42 is disposed at the bottom of the guide wheel mounting bracket 41, and at least one first traveling wheel 43 is rotatably connected to one side of the guide wheel mounting bracket 41 facing the first snap-fit ​​groove 32; the bottom of the guide wheel mounting bracket 41 is at least partially disposed in the disassembly groove 31, and the sides of the guide wheel mounting brackets 41 of the two sets of the first guide wheel assemblies 4 away from the first traveling wheel 43 are connected; the guide wheel mounting bracket 41 can slide along the sliding direction of the track of the sliding system using the first traveling wheel 43, and the two guide wheel mounting brackets 41 are spliced ​​to form a complete guide structure, which improves the guiding effect of the bidirectional damping buffer.

[0034] like Figures 1 to 8 As shown, further, the guide wheel mounting bracket 41 is provided with a shaft 44, the first traveling wheel 43 is rotatably connected to the shaft 44, and the wheel surface of the first traveling wheel 43 is provided with a groove 45; the guide wheel mounting bracket 41 is provided with a second snap-fit ​​groove 46 on one side of the first traveling wheel 43, and a snap-fit ​​member 47 is snap-fitted to the second snap-fit ​​groove 46, and the snap-fit ​​member 47 extends at least partially into the groove 45; the snap-fit ​​member 47 is used to realize the detachable connection between the first traveling wheel 43 and the guide wheel mounting bracket 41. During installation, the first traveling wheel 43 is sleeved on the shaft 44, and then the snap-fit ​​member 47 is fastened into the second snap-fit ​​groove 46, and a part of the snap-fit ​​member 47 is embedded into the groove 45 to restrict the axial movement of the first traveling wheel 43, so that the first traveling wheel 43 can be sleeved on the shaft 44 and maintain a relative rotation state.

[0035] In this embodiment, the fastener 47 can be a press-type fastener, a pressure plate type fastener, etc.; when the fastener 47 is a press-type fastener, its pressing part will extend into the groove 45 when it pops out and limit the first traveling wheel 43.

[0036] like Figures 1 to 8 As shown, further, the guide wheel mounting bracket 41 is provided with a connecting groove 48 at one end away from the mounting frame 1, and a brush part 49 is detachably connected in the connecting groove 48; by providing a connecting groove 48 at one end of the guide wheel mounting bracket 41, the brush part 49 can be detachably connected to the guide wheel mounting bracket 41, which facilitates the installer to replace the brush part 49 regularly; during installation, the brush part 49 only needs to slide its head into the connecting groove 48 to complete the connection with the guide wheel mounting bracket 41.

[0037] In one embodiment, a plug is provided on one side of the head of the brush part 49, and the plug abuts against the opening of the connecting groove 48; by providing the plug, the brush part 49 can be quickly positioned and installed in the connecting groove 48.

[0038] like Figures 1 to 8 As shown, further, the mounting frame 1 is provided with clamping grooves 12 on both sides of the opening of the mounting groove 11 along the length direction of the mounting frame 1; a connecting plate 13 is provided at the opening of the mounting groove 11, and clamping plates 14 are provided on both sides of the connecting plate 13 to cooperate with the clamping grooves 12; by providing clamping grooves 12 on both sides of the mounting frame 1, the connecting plate 13 can be quickly positioned and installed. The connecting plate 13 can improve the overall strength of the mounting frame 1 and avoid deformation of the mounting frame 1. At the same time, after the clamping plates 14 on both sides of the connecting plate 13 are connected to the clamping grooves 12, the clamping grooves 12 and clamping plates 14 are engaged by squeezing the side walls of the mounting frame 1, which further improves the firmness of the connection between the clamping plates 14 and the clamping grooves 12; in addition, by embedding the clamping plates 14 into the clamping grooves 12 to achieve hidden installation, the clamping plates 14 are hidden in the mounting groove 11, which improves the overall aesthetics of the mounting frame 1.

[0039] like Figures 1 to 8 As shown, further, positioning protrusions 15 are provided on both sides of the connecting plate 13, and positioning grooves 16 are provided on the clamping groove 12 to cooperate with and connect with the positioning protrusions 15; the positioning protrusions 15 and positioning grooves 16 cooperate to form a positioning structure, so that the connecting plate 13 and the mounting frame 1 can be quickly pre-assembled.

[0040] like Figures 1 to 8 As shown, the bidirectional damping assembly 2 further includes a bidirectional damper 21 and a buffer spring 22. The bidirectional damper 21 is slidably connected to the mounting groove 11. The output ends of the bidirectional damper 21 are respectively provided with a lever 7. The lever 7 is hinged to the output end of the bidirectional damper 21. The two ends of the lever 7 are slidably connected to the mounting frame 1. The two ends of the buffer spring 22 are respectively connected to the two levers 7. In use, when the lever 7 touches the stop assembly in the track of the sliding system, the lever 7 will drive the bidirectional damper 21 to slide under the resistance of the stop assembly. The bidirectional damper 21 will then provide damping force to the lever 7 in the opposite direction to slow down the sliding speed of the entire bidirectional damping buffer, thereby achieving the effect of buffering the moving body. At the same time, the buffer spring 22 also plays a buffering role, achieving the buffering treatment of the lever 7 through squeezing or stretching. The buffer spring 22 and the bidirectional damper 21 form a double buffer structure, thereby effectively improving the buffering effect of the bidirectional damping buffer.

[0041] In one embodiment, at least one vertical limiting block 18 is provided on each of the two sides of the mounting groove 11, and the bottom of the vertical limiting block 18 abuts against the bidirectional damper 21; the vertical limiting block 11 is used to improve the stability of the bidirectional damper 21 during sliding.

[0042] like Figures 1 to 8As shown, further, guide blocks 71 are respectively provided on both sides of the toggle block 7, and a hinge groove 72 is provided at the end of the toggle block 7 facing the output end of the bidirectional damper 21. A hinge rod 73 is provided in the hinge groove 72, and the hinge rod 73 is coaxially arranged with the guide blocks 71 on both sides. The output end of the bidirectional damper 21 is hinged to the hinge rod 73 through a hinge sleeve 23. A positioning post 74 is provided at the end of the toggle block 7 away from the hinge groove 72. Two toggle blocks are provided on both sides of the mounting frame 1 along its length. Each of the blocks 7 has a guide groove 17 communicating with the mounting groove 11. The guide slider 71 is slidably connected to the guide groove 17. One end of the guide groove 17 near the end of the mounting frame 1 bends downward to form a locking position 19 that cooperates with the positioning post 74. The bottom of the push block 7 has a clamping groove 75 that cooperates with the buffer spring 22. By setting the locking position 19 at the end of the guide groove 17, the sliding of the push block 7 can be restricted. When the positioning post 74 slides into the locking position 19, the positioning post 74 will slide into the locking position. 19. To limit the slippage of the lever 7; in addition, when the positioning post 74 slides down into the locking position 19, the lever 7 as a whole will generate a certain swing amplitude. Under normal settings, since the output end of the bidirectional damper 21 is located at the end of the lever 7 away from the positioning post 74, when the lever 7 rotates towards the locking position 19, it will cause the output end of the bidirectional damper 21 to swing upward, resulting in the problem of unstable slippage of the bidirectional damper 21. In this embodiment, the output end of the bidirectional damper 21 is coaxially set on the two guide sliders 7 of the lever 7. Between 1, by means of coaxial arrangement, when the toggle block 7 rotates, it will rotate around the axis of the two guide sliders 71. The output end of the bidirectional damper 21 is hinged to the hinge rod 73 through the hinge sleeve 23. Therefore, the output end of the bidirectional damper 21 is coaxial with the axis of the two guide sliders 71. The output end of the bidirectional damper 21 will rotate relative to the hinge rod 73. Even if the toggle block rotates, it will not cause the output end of the bidirectional damper 21 to swing, thereby avoiding the bidirectional damper 21 from jumping in the mounting groove 11.

[0043] In one embodiment, the top of the toggle block 7 is provided with a toggle protrusion, and a noise-absorbing pad 76 is detachably connected to the toggle protrusion. By providing the noise-absorbing pad 76, the toggle protrusion will not generate noise from a hard collision when it comes into contact with the stop component in the track, thus improving the user experience. In addition, the noise-absorbing pad 76 and the toggle protrusion are connected by a snap-fit, which makes it easy to replace the noise-absorbing pad 76, allowing the user to replace the noise-absorbing pad 76 periodically.

[0044] like Figures 1 to 8As shown, further, the guide wheel assembly 5 includes a first wheel body connecting frame 51, one end of which is connected to the mounting groove 11. A second traveling wheel 52 is rotatably connected to the side of the first wheel body connecting frame 51 away from the second guide wheel assembly 6. A first slide rail portion 53 is provided on the side of the first wheel body connecting frame 51 near the second guide wheel assembly 6. The second guide wheel assembly 6 includes a second wheel body connecting frame 61, on which a second slide rail portion 62 is provided that is slidably connected to the first slide rail portion 53. A third traveling wheel 63 is rotatably connected to the side of the second wheel connecting frame 61 away from the second slide rail portion 62. A screw hole 64 penetrating the second slide rail portion 62 is provided at the bottom of the second wheel body connecting frame 61. A slot 54 is provided on the first slide rail portion 53 corresponding to the position of the screw hole 64. A second locking member 65 is threadedly connected to the screw hole 64. The free end of the second locking member 65 extends into the slot 54. During installation, one end of the first wheel body connecting frame 51 is pre-connected to the mounting groove 11. After the first wheel body connecting frame 51 and the mounting frame 1 can be placed into the track of the sliding system, the second wheel body connecting frame 61 is also placed into the track. The first wheel body connecting frame 51 and the second wheel body connecting frame 61 are connected and installed by using the second slide rail part 62 and the first slide rail part 53, so that the second wheel body connecting frame 61 slides and locks on one side. Finally, the second locking member 65 is turned so that it extends from the screw hole 64 into the slot 54 to lock the first slide rail part 53 and the second slide rail part 62, thereby realizing the installation connection of the first wheel body connecting frame 51 and the second wheel body connecting frame 61. The above structure realizes the quick connection of the first wheel body connecting frame 51 and the second wheel body connecting frame 61, which is convenient for installers to disassemble and adjust the bidirectional damping buffer after installation.

[0045] In summary, the bidirectional damping component 2 achieves damped movement of the bidirectional damping buffer, effectively preventing hard collisions between the sliding body and the sliding system, thus achieving buffering and shock absorption effects. The guide portion of the bidirectional damping buffer is designed as a split structure, including a mounting base 3, two sets of first guide wheel assemblies 4, a guide wheel seat assembly 5, and a second guide wheel assembly 6. This split structure allows the bidirectional damping buffer to be installed later and can be inserted into the sliding system track by tilting, effectively reducing installation difficulty and improving installation flexibility. The split structure also allows the bidirectional damping buffer to be installed individually from the opening of the sliding surface of the track, rather than being inserted as a whole from the end entrance of the sliding system track, further improving installation convenience and flexibility.
