Description

Technical Field

[0001] The utility model relates to the technical field of furniture drawers, in particular to a hidden slide rail with a pressing synchronous rebound opening function. Background Art

[0002] In our current life, drawers are a common appliance in our lives, and drawers usually need to be used with slide rails. Slide rails, also known as slide rails, slideways, refer to hardware connection components fixed to the cabinet body of furniture for the drawers or cabinet panels of furniture to move in and out. Slide rails are suitable for drawer connections of wooden and steel drawers in cabinets, furniture, document cabinets, bathroom cabinets and other furniture.

[0003] However, the existing slide rails have the following shortcomings:

[0004] The self-closing angle type slide rail has a section of the slide rail that is slightly tilted downward at the rear end of the fixed rail, so that the front roller of the movable slide rail installed on the drawer will automatically slide down under the action of its own weight when it moves to the inclined section, thereby ensuring that the drawer is completely closed. However, when the roller of the movable slide rail is pushed to the lower end of the slide, the roller can only slide down a slope of 2.5 to 3 degrees due to the weight of the drawer alone, and the sliding closure is not obvious, and the use effect is very unsatisfactory; due to the small bending angle and the inability to self-lock, when the drawer is slightly tilted outward, it will slide out and fall to the ground; because the drawer has no self-locking function, when moving the table, the drawer is easy to slide out under the action of its own weight, causing inconvenience in moving.

[0005] When pushing a drawer, if you only push one side of the drawer or deviate from the center of the drawer, it is easy for the left and right sides of the drawer to be out of sync when pushing and pulling. This rebound slide can only be used for small drawers. Once used on large or heavy slides, the slides will not be pushed forward synchronously due to different forces acting on the two sides of the slides, causing the slides to tilt and get stuck due to unbalanced forces, poor stability, increased failure rate of the slides, and poor or impossible operation of the slides. The press-rebound devices on both sides of the slides are not synchronized, which can easily cause the press-rebound devices to be unstable in connection with the pushing and pressing rebound actions, resulting in mutual interference between components, and the press-rebound devices will also get stuck.

[0006] When the press-rebound device cooperates with the damping device, the press-rebound device has a complex structure, which leads to poor structural coordination stability when the rebound device cooperates with the damping device, and is prone to problems such as jamming. The rebound device is prone to excessive speed under the rebound effect, which poses a safety hazard.

[0007] With the development of society and the continuous changes in people's thoughts and behaviors, many new requirements have been put forward for the use of various things in daily life. Therefore, the requirements for the humanization and simplification of functional slides are getting higher and higher. In order to meet people's needs in real life, a slide with buffer self-locking, rebound opening and linkage opening functions is needed in furniture, especially high-end furniture.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0037] like Figure 1 and 2As shown, a hidden slide rail with a press-synchronous rebound opening function includes a fixed slide rail 1 and a movable slide rail 2 installed therein and movable relative thereto, the movable slide rail 2 includes a middle rail 21 and an inner rail 22, and also includes:

[0038] like Figure 3 and 4 As shown, the rebound self-locking mechanism 3 is used for rebounding and self-locking the movable slide rail 2, including a sliding bar 31, a first swing hook 32, and a first elastic member 33. One end of the first swing hook 32 is swingably connected to the sliding bar 31, and the first elastic member 33 makes the sliding bar 31 have a tendency to slide in the direction of withdrawing the movable slide rail 2; the rebound self-locking mechanism 3 also includes a third elastic member 34, and a first groove 72 is provided on the main bracket 7 for accommodating the first elastic member 33. One end of the first elastic member 33 is clamped on the main bracket 7, and the other end is clamped on the sliding bar 31; the main bracket 7 is provided with a second groove 7 3 is used to accommodate the second elastic member 54, one end of the second elastic member 54 is clamped on the main bracket 7, and the other end is clamped on the synchronous rack 51; the sliding bar 31 is provided with a third groove 311 for accommodating the third elastic member 34, one end of the third elastic member 34 is clamped on the sliding bar 31, and the other end is clamped on the sliding block 42, and the third elastic member 34 makes the sliding block 42 have a tendency to slide in the closing direction of the movable slide rail 2; the main bracket 7 is provided with a fourth groove 74 for accommodating the automatic extension cylinder 43, and the movable end of the automatic extension cylinder 43 is clamped on the sliding block 42. The first swing hook 32 includes a first self-locking block 321, a second self-locking block 322 and a third self-locking block 323. The first self-locking block 321 contacts the first selector bar 61 to drive the sliding block 42 to slide. The second self-locking block 322 has a first inclined surface 3221 and a second inclined surface 3222. The second self-locking block 322 drives the sliding bar 31 to press against the main bracket 7 to lock the rebound self-locking mechanism 3. A channel is formed among the first self-locking block 321, the second self-locking block 322 and the third self-locking block 323 for the first selector bar 61 to pass through.

[0039] like Figure 5 and 6 As shown, the buffer mechanism 4 is used for buffering in conjunction with the rebound self-locking mechanism 3 when the movable slide rail 2 is opened or closed, and includes a second swing hook 41, a sliding block 42, and an automatic extending cylinder 43. One end of the second swing hook 41 is swingably connected to the sliding block 42, and the automatic extending cylinder 43 makes the sliding block 42 have a tendency to slide in the withdrawal direction of the movable slide rail 2; a slot 411 is provided on the second swing hook 41, and the second selector bar 62 moves in the closing direction of the movable slide rail 2. When passing through the second swing hook 41, the second selector bar 62 is inserted into the slot 411, and the second swing hook 41 is linked to swing away from the convex position 75, and moves synchronously with the second selector bar 62; the second selector bar 62 moves in the withdrawal direction of the movable slide rail 2, and when the second swing hook 41 is linked to move to the convex position 75, the second swing hook 41 swings to hook the convex position 75 and the slot 411 is tilted to allow the second selector bar 62 to leave the slot 411 and continue to move.

[0040] like Figure 6 and 7 As shown, the synchronization mechanism 5 is used to link with the synchronization mechanism 5 of the hidden slide rail on the other side of the drawer. The synchronization mechanism 5 is arranged on the main bracket 7, and includes a synchronization rack 51, a synchronization sleeve 52, a synchronization connecting rod 53 and a second elastic member 54. The synchronization sleeve 52 is sleeved on the end of the synchronization connecting rod 53, and the synchronization sleeve 52 and the synchronization rack 51 sleeve are transmitted. The second elastic member 54 connects the main bracket 7 and the synchronization rack 51. The sliding bar 31 pushes the synchronization rack 51 to slide inward and then resets. The synchronization connecting rod 53 drives the synchronization sleeve 52 on the other side to rotate and the synchronization rack 51 to slide. The guiding inclined surface 511 of the synchronization rack 51 on the other side contacts the unlocking surface 324, driving the first swing hook 32 to unlock, and the hidden slide rails on both sides automatically pop open at the same time. Springs are also installed in the synchronization sleeves on both sides. The springs support the two ends of the synchronization connecting rod 53 to make it more stable in position, ensuring a reliable connection.

[0041] like Figures 8 to 10 As shown, the linkage bar 6 includes a first bar 61 and a second bar 62, both of which are arranged on the inner rail 22. The first bar 61 is linked with the first swing hook 32 to make the movable slide rail 2 rebound and self-lock, and the second bar 62 is linked with the second swing hook 41 to make the movable slide rail 2 buffer; the synchronous connecting rod 53 is polygonal, one end of the synchronous shaft sleeve 52 is sleeved on the end of the synchronous connecting rod 53, and the other end has teeth 521, and the teeth 521 mesh with the synchronous rack 51, and one end of the second elastic member 54 is clamped on the synchronous rack 51, and the other end is clamped on the main bracket 7. During the sliding process of the movable slide rail 2, the first bar 61 only contacts the first swing hook 32, and the second bar 62 only contacts the second swing hook 41. When the first bar 61 moves in the closing direction of the movable slide rail 2, it pushes the first swing hook 32 to move until it is clamped into the concave position 76. The spacing between the first pull bar 61 and the second pull bar 62 is greater than the minimum spacing between the first swing hook 32 and the second swing hook 41. The main bracket 7 is fixedly arranged on the fixed slide rail 1, and the rebound self-locking mechanism 3, the buffer mechanism 4 and the synchronization mechanism 5 are arranged on the main bracket 7; the main bracket 7 has a slide groove 71, and the slide bar 31, the first swing hook 32, the second swing hook 41, the slide block 42 and the synchronization rack 51 are movably arranged in the slide groove 71. A convex position 75 is arranged at one end of the main bracket 7 close to the extraction direction of the movable slide rail 2. When the slide block 42 slides to the convex position 75, the other end of the second swing hook 41 swings and hooks the convex position 75, and the slide block 42 cannot slide in the closing direction of the movable slide rail 2. A recess 76 is provided at one end of the main bracket 7 close to the closing direction of the movable slide rail 2. The third self-locking block 323 enters the recess 76, and the rebound self-locking mechanism 3 is locked. An unlocking inclined surface 77 is provided on the inner side of the recess 76, and the third self-locking block 323 disengages from the recess 76 along the unlocking inclined surface 77.

[0042] The process of realizing synchronous rebound, buffering and self-locking of the slide rail in the utility model is as follows:

[0043] The drawer is in the open state, the second swing hook 41 is stuck in the convex position 75, closing the drawer, and the inner rail 22 slides inward. The first selector bar 61 contacts the third self-locking block 323 along the first inclined surface 3221, and pushes the first swing hook 32 and the sliding bar 31 to slide into the drawer. The first elastic member 33 stretches and generates resistance, and then the second selector bar 62 falls into the slot 411 of the second swing hook 41. At the same time, the third self-locking block 323 on the first swing hook 32 is stuck in the concave position 76. Then the second selector bar 62 pushes the second swing hook 41 to disengage from the convex position 75. The sliding block 42 is pulled toward the sliding bar 31 due to the pull of the third elastic member 34, and the inner rail 22 is linked to slide inward. At the same time, it is necessary to overcome the damping generated by the compression of the automatic extension cylinder 43. The third elastic member 34 drives the drawer to close slowly and evenly to achieve self-locking. At this time, the drawer is in the closed state.

[0044] The drawer is in the closed state, and the drawer is pressed to continue to slide inward. The second pull bar 62 pushes the second swing hook 41 and the sliding block 42 connected thereto, and pushes the first swing hook 32, the sliding bar 31 and the synchronous rack 51 to slide inward. The synchronous sleeve 52 rotates with the synchronous rack 51, driving the synchronous connecting rod 53 to rotate and driving the synchronous sleeve 52 on the other side to rotate, driving the synchronous rack 51 of the hidden slide rail on the other side to slide inward. This process needs to continue to overcome the resistance generated by the compression of the automatic extension cylinder 43 and the second elastic member 54. The guiding inclined surface 511 guides the first swing hook 32 to disengage from the recessed position 76 along the unlocking surface 324, thereby releasing the self-locking. Subsequently, the first elastic member 33 and the second elastic member 54 generate elastic force, automatically extend The oil outlet cylinder 43 extends to generate thrust, pushing the synchronous rack 51, the sliding bar 31 and the sliding block 42 to slide outward from the drawer, linking the second swing hook 41 to slide outward, and the slot 411 of the second swing hook 41 clamps the second strip 62, linking the inner rail 22 to slide outward until the sliding block 42 slides to the end of the slide groove 71 and cannot slide further, the second swing hook 41 swings to clamp the protrusion 75, and the second swing hook 41 swings to a position suitable for the second strip 62 to move laterally away. At this time, the second strip 62 disengages from the slot 411 and continues to slide outward with the sliding rail 2, and the first strip 61 slides outward along the channel of the first swing hook 32, and the first strip 61 contacts the second inclined surface 3222, so that the first swing hook 32 is reset, and the drawer is fully opened.

[0045] When the drawer is in a closed state, the drawer can also be directly pulled out by overcoming the elastic force. At this time, the drawer is directly pulled out, the movable slide rail 2 moves outward, and the first swing hook 32 remains in the recessed position 76. The first selector bar 61 will not contact the first swing hook 32 when passing the position of the first swing hook 32, and the sliding bar 31 and the first swing hook 32 both remain in their original state; the second selector bar 62 pushes the second swing hook 41, and at the same time, the second swing hook 41 links the sliding block 42 to slide outward, and the oil cylinder 43 automatically extends to generate thrust, pushing the sliding block 42 and the second swing hook 41 to slide outward. At the same time, it is necessary to overcome the elastic force generated by the stretching of the third elastic member 34 until the second swing hook 41 swings and grabs the convex position 75, and the second swing hook 41 swings to a suitable position for the second selector bar 62 to move horizontally away. At this time, the second selector bar 62 disengages from the slot 411 and continues to slide outward with the movable slide rail 2, and the drawer is fully opened.

[0046] The drawer is in the open state, and the first swing hook 32 remains in the recessed position 76. To close the drawer, the movable slide rail 2 slides inward, and the second selector bar 62 first contacts the second swing hook 41 and is inserted into the slot 411 of the second swing hook 41. The second swing hook 41 disengages from the protruding position 75, pushing the second swing hook 41 into the drawer, and links the sliding block 42 to slide inward. Subsequently, the third elastic member 34 retracts to generate elastic force to drive the sliding block 42 to slide toward the sliding bar 31, and partially offsets the resistance generated by the automatic extension of the oil cylinder 43, thereby achieving a buffering effect, until the sliding block 42 contacts the sliding bar 31 and no longer slides inward, and the drawer slowly closes.

[0047] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
