[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4As shown, this utility model provides a double-track damping buffer device for a laboratory cabinet drawer, including a housing 1. A sliding mechanism 2 is provided on the inner side of the housing 1. A mounting mechanism 3 is fixedly provided on the upper surface of the sliding mechanism 2. The sliding mechanism 2 includes a sliding plate 20, the two sides of which slide against the inner walls of the two sides of the housing 1. Multiple sliders 22 arranged in a rectangular array are fixedly provided on the lower surface of the sliding plate 20. Two slide rails 24 are fixedly provided on the lower inner wall of the housing 1, and the slide rails 24 slide against the sliders 22. A damping positioning block 29 is fixedly provided on the lower surface of the sliding plate 20. A damping guide rail 26 is fixedly installed on the lower inner wall. The upper surface of the damping guide rail 26 slides against the damping positioning block 29. A drag chain 23 is fixedly installed on both sides of the damping positioning block 29. One end of the drag chain 23 is fixedly connected to one side of the inner wall of the outer shell 1. Two symmetrically distributed fixing brackets 25 are fixedly installed on one side of the inner wall of the outer shell 1. One side of each fixing bracket 25 is fixedly connected to one end of the drag chain 23. When using this double-track damping buffer device for the drawer of the experimental cabinet, when the drawer needs to be opened, an outward pulling force is applied to the drawer. The drawer moves the sliding plate 20 through the mounting mechanism 3. The sliding plate 20 slides along the sliding grooves 28 on both sides of the outer shell 1, while multiple sliders 22 on its lower surface slide on two slide rails 24, achieving smooth linear motion. During the sliding process, the damping positioning block 29 on the lower surface of the sliding plate 20 slides and engages with the damping guide rail 26 through the positioning groove 27 on its lower surface. The damping guide rail 26 provides damping force, preventing the drawer from rushing out quickly due to excessive force during opening, thus achieving a buffering effect. When the drawer is closed, it slowly and smoothly returns to its original position under the damping action of the damping guide rail 26, avoiding impact with the cabinet. During this process, the drag chains 23 on both sides of the damping positioning block 29 extend and retract with the movement of the sliding plate 20. One end of the drag chain 23 is connected to the sliding plate 20, and the other end is fixed to the inner wall of the outer casing 1 through the fixing bracket 25, which plays a sliding limit role, preventing the sliding plate 20 from moving excessively, and reducing wear on internal wiring and other components caused by the drawer sliding.

[0024] Specifically, the mounting mechanism 3 includes a mounting bracket 30 located on the upper surface of the sliding plate 20. Two mounting cylinders 34 are fixedly mounted on the lower surface of the mounting bracket 30. Multiple limiting beads 39 are movably mounted on the outer side of each mounting cylinder 34. A mounting screw 33 is threaded into the inner side of each mounting cylinder 34. A knob 31 is fixedly mounted on the upper end of the mounting screw 33, and an ejector rod 35 is fixedly mounted on the lower end of the mounting screw 33. A limiting rod 36 is fixedly mounted on the lower end of the ejector rod 35. Multiple limiting holes 38 are opened on the outer side of the mounting cylinder 34, and the inner side of each limiting hole 38 is movably connected to the limiting beads 39. When installing the drawer, the mounting bracket 30 is first placed on the upper surface of the sliding plate 20, allowing the mounting cylinders 34 to slide along the limiting grooves 37 on the upper surface of the sliding plate 20 to ensure accurate positioning of the mounting bracket 30. Then, according to the actual specifications of the drawer and installation requirements, the knob 31 is rotated. The anti-slip texture 32 on the outer side of the knob 31 increases friction, facilitating operation. Knob 31 drives the mounting screw 33 to rotate threaded inside the mounting cylinder 34. The mounting screw 33 moves downward, pushing the ejector rod 35 and the limit rod 36 downward. The limit rod 36 pushes the limit bead 39 to partially extend from the limit hole 38 on the outside of the mounting cylinder 34. When the limit bead 39 contacts and locks into place with the corresponding structure on the drawer, the drawer is initially fixed to the mounting bracket 30. Finally, using bolts or other tools, the drawer is further securely connected to the mounting bracket 30 through the multiple drawer mounting holes 301 on the upper surface of the mounting bracket 30, thus completing the drawer installation.

[0025] Furthermore, the sliding grooves 28 on both sides of the outer shell 1 slide against the sides of the sliding plate 20. This design provides precise guidance for the movement of the sliding plate 20, ensuring that the sliding plate 20 can only slide smoothly in a straight line without deviation or shaking, thus improving the stability and reliability of the drawer sliding and ensuring the smoothness of the drawer during opening and closing.

[0026] Furthermore, multiple fixing holes 21 on the upper surface of the slider 22 are fixedly engaged with the sliding plate 20. Through these fixing holes 21, fasteners such as bolts can be used to firmly install the slider 22 onto the sliding plate 20, which enhances the connection strength between the slider 22 and the sliding plate 20. This ensures that the slider 22 will not easily loosen or fall off during long-term use, thus guaranteeing the normal operation of the sliding mechanism 2.

[0027] It is worth noting that the positioning groove 27 on the lower surface of the damping positioning block 29 slides and fits with the damping guide rail 26. The positioning groove 27 can cooperate more precisely with the damping guide rail 26, making the sliding of the damping positioning block 29 on the damping guide rail 26 more stable. This further improves the buffering effect of the drawer during the opening and closing process, ensuring that the drawer can move smoothly and slowly, and avoiding jamming or abnormal vibration caused by inaccurate cooperation between the damping positioning block 29 and the damping guide rail 26.

[0028] It is worth noting that the multiple drawer mounting holes 301 on the upper surface of the mounting bracket 30 provide multiple fixing points for the connection between the drawer and the mounting bracket 30. The appropriate mounting hole 301 can be selected for connection according to the actual specifications of the drawer and the installation requirements, making the installation of the drawer more secure and stable, while also increasing the flexibility of installation and adapting to the installation of drawers of different types and sizes.

[0029] It is worth mentioning that the two limiting grooves 37 fixed on the upper surface of the sliding plate 20 slide and fit in contact with the mounting cylinder 34. The limiting grooves 37 provide precise guidance and limitation for the installation and sliding of the mounting cylinder 34, ensuring that the mounting cylinder 34 can only slide along the direction of the limiting grooves 37 without deviation. This makes the installation mechanism 3 more accurate and convenient during installation and adjustment, and improves the installation accuracy and stability of the installation mechanism 3.

[0030] It is worth emphasizing that the multiple ring-shaped anti-slip textures 32 on the outer side of the knob 31 increase the friction of the knob 31 surface. When the operator rotates the knob 31, even if the hands are sweaty or oily, the operator can more easily hold the knob 31 and apply rotational force, which facilitates the operation of the mounting screw 33 and improves the ease of use and comfort of operation of the mounting mechanism 3.

[0031] Working Principle: When using the double-track damping buffer device for the drawer of this experimental cabinet, when the drawer needs to be opened, an outward pulling force is applied to the drawer, causing the drawer to move via the mounting mechanism 3, which in turn moves the sliding plate 20. The sliding plate 20 slides along the sliding grooves 28 on both sides of the outer casing 1, while multiple sliders 22 on its lower surface slide on two slide rails 24, achieving smooth linear motion. During the sliding process, the damping positioning block 29 on the lower surface of the sliding plate 20 slides against the damping guide rail 26 through its positioning groove 27. The damping guide rail 26 provides damping force, preventing the drawer from rushing out quickly due to excessive force during opening, thus achieving a buffering effect. When the drawer is closed, it slowly and smoothly returns to its original position under the damping action of the damping guide rail 26, avoiding impact with the cabinet body. During this process, the drag chains 23 on both sides of the damping positioning block 29 extend and retract with the movement of the sliding plate 20. One end of the drag chain 23 is connected to the sliding plate 20, and the other end is fixed to the inner wall of the outer casing 1 through the fixing bracket 25, which plays a sliding limit role, prevents the sliding plate 20 from moving excessively, and reduces the wear of internal circuits caused by the sliding of the drawer.

[0032] When installing the drawer, first place the mounting bracket 30 on the upper surface of the sliding plate 20, allowing the mounting cylinder 34 to slide along the limiting groove 37 on the upper surface of the sliding plate 20 to ensure accurate positioning of the mounting bracket 30. Then, according to the actual specifications of the drawer and installation requirements, rotate the knob 31. The anti-slip texture 32 on the outer side of the knob 31 increases friction for easy operation. The knob 31 drives the mounting screw 33 to rotate threaded inside the mounting cylinder 34, causing the mounting screw 33 to move downwards, pushing the ejector rod 35 and the limiting rod 36 downwards. The limiting rod 36 pushes the limiting bead 39 to partially extend from the limiting hole 38 on the outer side of the mounting cylinder 34. When the limiting bead 39 contacts and locks into place with the corresponding structure on the drawer, the initial fixing of the drawer to the mounting bracket 30 is completed. Finally, using bolts or other tools, further securely connect the drawer to the mounting bracket 30 through the multiple drawer mounting holes 301 on the upper surface of the mounting bracket 30 to complete the drawer installation.
