Description

Technical Field

[0001] This utility model relates to the field of slide rail device technology, and in particular to a smooth slide rail with a buffer. Background Technology

[0002] Pull-out cabinets or drawers are widely used in various storage and containment appliances. To facilitate the pulling out of the cabinet (drawer), the cabinet is usually combined with the positioning and guiding of the slide rails on both sides. In addition, to facilitate the stability and quietness when the cabinet is pushed and closed, the slide rails are often further combined with a buffer mechanism. When the cabinet is pushed to the end, the buffer mechanism will play a buffering role, so as to avoid the cabinet from making a large impact and collision noise, thus maintaining the service life of the cabinet and providing a better cabinet operation feel.

[0003] However, drawer slides are generally made of metal, with the outer, middle, and inner rails sliding relative to each other during a self-locking process. A common problem during use is that when the slide is closed, uneven force is distributed on the inner side of the inner rail due to the position and number of elastic and buffer components. This causes the entire drawer to wobble from side to side when pulled out, leading to collisions of multiple parts and significant noise. Therefore, improving the drawer slide structure to further enhance its stability and smoothness is a problem we need to address. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide a smooth slide rail with a buffer.

[0005] To solve the above-mentioned technical problems, this utility model provides a smooth slide rail with a buffer. The slide rail includes a fixed slide rail and a movable slide rail installed therein and movable relative to it. The movable slide rail includes a middle rail and an inner rail, and includes a fixed seat, a sliding block, a damping element and two elastic elements.

[0006] The fixed seat is fixedly disposed on the inner wall of the tail end of the fixed slide rail, the sliding block is slidably disposed on the fixed seat, the damping element is disposed in the middle of the fixed seat, and the sides of both sides of the fixed seat are provided with receiving grooves. The elastic element is disposed in the receiving grooves. The two ends of the damping element and the elastic element are respectively connected to the fixed seat and the sliding block, so that the sliding block has elastic stress towards the fixed seat.

[0007] Furthermore, it also includes a self-locking fork and a hook. The center of the fixed base is provided with a self-locking groove. The self-locking fork is oscillatingly disposed within the sliding block and has an upper guide post and a lower guide post. The hook is disposed at the tail of the inner rail. The upper guide post passes through the sliding block and is movably engaged with the hook. The lower guide post slides within the self-locking groove. The self-locking groove has a locking position, which is used to lock or unlock the sliding block.

[0008] Furthermore, the inner wall of the hook has a recess, and the two sides of the recess are provided with an inlet ramp and an outlet ramp. When the upper guide post falls into or leaves the recess, the self-locking fork deflects.

[0009] Furthermore, the upper guide post falls into the recess along the guide slope, the lower guide post disengages from the locking position, and the sliding block unlocks and slides on the fixed seat.

[0010] Furthermore, the upper guide post disengages from the recess along the inclined surface, the lower guide post falls into the locking position, and the sliding block is locked onto the fixed seat.

[0011] Furthermore, the damping element includes a hydraulic cylinder body and a piston rod. The hydraulic cylinder body is fixedly mounted on the fixed base. One end of the piston rod is telescopically mounted inside the hydraulic cylinder body, and the other end is connected to the sliding block. The elastic element is a tension spring.

[0012] Furthermore, when the slide rail is closed, pulling the inner rail causes the self-locking fork to slide along the self-locking groove via the hook. The elastic element generates a pulling force, and the damping element generates a damping force, until the self-locking fork deflects, disengages from the recess, and falls into the locking position. The sliding block is locked on the fixed seat, the inner rail separates from the sliding block, and the movable slide rail can be pulled open.

[0013] Furthermore, when the slide rail is in the open state, pushing the inner rail causes the self-locking fork to deflect via the hook, fall into the recess and disengage from the locking position. Under the action of the elastic member's pulling force, the sliding block moves inward, the damping member generates damping force, and the slide rail overcomes the damping of the damping member and slowly closes.

[0014] Furthermore, the sliding block has a through hole and a placement groove in its middle part, and the damping element is disposed in the placement groove.

[0015] Furthermore, the sliding block is provided with reinforcing ribs along its central edge.

[0016] Implementing the embodiments of this utility model has the following beneficial effects:

[0017] When closing the drawer, simply push it inwards. The self-locking fork engages with the hook, causing the inner rail to slide. The lower guide post of the self-locking fork slides in the self-locking groove. Under the elastic force of the two tension springs, the moving slide rail is pulled to the end of the fixed slide rail, thus locking the drawer. Through the balanced setting of the two springs on both sides of the fixed base and the damping component in the middle, the force is more even when the sliding block is pulled, achieving smoothness and stability of the slide rail closing slowly. The structure is simple, easy to assemble, and has low production cost, thus improving market competitiveness. Attached Figure Description

[0032] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0033] Example 1:

[0034] like Figure 1 As shown, a smooth-flowing slide rail with a damper includes a fixed slide rail 1 and a movable slide rail 2 installed within it and movable relative to it. The movable slide rail 2 includes a middle rail 21 and an inner rail 22, and includes a fixed seat 3, a sliding block 4, a damping element 5, and two elastic elements 6. The fixed seat 3 is fixedly disposed on the inner wall of the tail end of the fixed slide rail 1. The sliding block 4 is slidably disposed on the fixed seat 3. The damping element 5 is disposed in the middle of the fixed seat 3. Receiving grooves 31 are provided on both sides of the fixed seat 3. The elastic elements 6 are disposed in the receiving grooves 31. The two ends of the damping element 5 and the elastic elements 6 are respectively connected to the fixed seat 3 and the sliding block 4, so that the sliding block 4 has elastic stress towards the fixed seat 3. Preferably, the middle edge of the sliding block 4 is provided with a reinforcing rib 43, making the sliding block more durable. The elastic element 6 is a tension spring. Through the balanced arrangement of the two elastic elements 6 on both sides of the fixed seat and the damping element 5 in the middle, the force is more even when the sliding block 4 is pulled, realizing the smoothness and stability of the slide rail closing slowly.

[0035] It should be noted that in this embodiment, the elastic element 6 is disposed on both sides of the fixed base 3 and the damping element 5 is disposed in the middle of the fixed base 3. However, the key is to balance the elastic force of the damping element 5 and the elastic element 6 to make the slide rail move more smoothly and stably. Therefore, any simple changes in the position and number of the damping element 5 and the elastic element 6, or similar methods, that are imitated by other manufacturers, sellers or users with only minor modifications should be considered as equivalent infringement.

[0036] The damping component 5 includes a hydraulic cylinder body 51 and a piston rod 52. The hydraulic cylinder body 51 is fixedly mounted on the fixed base 3. One end of the piston rod 52 is telescopically mounted inside the hydraulic cylinder body 51, and the other end is connected to the sliding block 4.

[0037] The self-locking fork 7 and hook 8 are located in the middle of the fixed base 3, where a self-locking groove 32 is provided. The self-locking fork 7 is oscillatingly positioned within the sliding block 4 and has an upper guide post 71 and a lower guide post 72. The hook 8 is located at the tail of the inner rail 22. The upper guide post 71 passes through the sliding block 4 and is movably engaged with the hook 8. The lower guide post 72 slides within the self-locking groove 32, which has a locking position 321 for locking or unlocking the sliding block 4. The hook 8 has a recess 81 on its inner wall, with an inlet ramp 82 and an outlet ramp 83 on both sides. When the upper guide post 71 falls into or leaves the recess 81, the self-locking fork 7 deflects.

[0038] The specific working principle of the smooth-flowing slide rail with buffer of this utility model is as follows:

[0039] With the drawer closed, pulling the inner rail 22 causes the inner rail 22 to slide along the self-locking fork 7 via the hook 8. The elastic element 6 is stretched to generate tension, and the damping element 5 generates damping force until the self-locking fork 7 deflects. The upper guide post 71 disengages from the recess 81 along the guide slope 83, and the lower guide post 72 falls into the locking position 321. The sliding block 4 is locked on the fixed seat 3, and the inner rail 22 separates from the sliding block 4. The movable drawer 2 can continue to be pulled open until the drawer is fully opened.

[0040] With the drawer open, push the inner rail 22. The inner rail 22 causes the self-locking fork 7 to deflect via the hook 8. The upper guide post 71 falls into the recess 81 along the guide slope 82, and the lower guide post 72 disengages from the locking position 321. The sliding block 4 is unlocked and can slide on the fixed seat 3. Under the action of the elastic element 6, the sliding block 4 moves inward, and the damping element 5 generates damping force. The drawer overcomes the damping of the damping element 5 and slowly closes until the drawer is completely closed.

[0041] Example 2:

[0042] like Figure 11 and 12 As shown, this embodiment of a smooth slide rail with a buffer has the same main structure as the first embodiment, except that: the middle part of the sliding block 4 is provided with a through hole 41 and a placement groove 42. The through hole 41 is used to facilitate the installation of screws during assembly, and the damping element 5 is disposed in the placement groove 42.

[0043] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
