Description

Technical Field

[0001] The invention relates to the technical field of slide rail devices, and in particular to a stable slide rail with adjustable rebound elastic force. Background Art

[0002] When the existing drawer slide rail is in use, the operator acts on the drawer, so that the drawer drives the slide rail to extend and retract, thereby realizing the pushing and pulling of the drawer.

[0003] At present, drawers of various office desks are equipped with slide rails. In order to make the drawer close to the desk after closing, it looks neat and beautiful. The existing technology adopts a self-closing angle rail of international general design, and a section of the guide rail is slightly inclined downward at the rear end of the fixed rail, so that the front roller of the sliding rail installed on the drawer automatically slides down under the action of its own weight when it moves to the inclined section, thereby ensuring that the drawer is completely closed. However, this self-closing angle rail has always had the following shortcomings: If the spring force used is insufficient, the drawer may not be able to close properly. If the spring force used is too large, when the overall weight of the cabinet is light, it is easy to cause the entire cabinet to move when the drawer is opened, but the drawer is still not fully opened; When a drawer is tilted slightly outward, there is a risk that the drawer will slide out and fall to the ground; Since the drawers do not have a self-locking function, when the table is moved, the drawers can easily slide out under their own weight, making it inconvenient to move.

[0004] The patent application number 2024116257118 filed by the applicant on November 14, 2024 discloses an invention of a slide rail with an elastically adjustable rebound self-locking device, which includes a fixed seat, a first sliding block, a second sliding block, an elastic member, a damping member, a self-locking fork, and a hook; the second sliding block is connected to the first sliding block through an elastic member so that it has an elastic stress toward the first sliding block, and an elastic adjustment mechanism is provided on the fixed seat, and the elastic adjustment mechanism is used to adjust the relative distance between the first sliding block and the second sliding block, thereby adjusting the elastic force of the elastic member. The present invention has a simple structure, convenient assembly, low production cost, and improved market competitiveness; an elastic adjustment mechanism is provided in the elastically adjustable buffer, which can change the elastic force provided by adjusting the stroke of the elastic member, thereby adjusting the switch elastic force of the guide rail, so that the user can open and close the drawer more conveniently and comfortably to meet the needs of different drawers; the stroke of the adjustment tooth groove can be adaptively adjusted according to the elastic force of the elastic member, and adapt to more types of elastic members. However, the first sliding block of the application is arranged above the fixing seat, which is prone to displacement and damage and is not stable enough. Summary of the invention

DETAILED DESCRIPTION

[0017] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Embodiment 1: like Figure 1-12 As shown, a stable slide rail with adjustable rebound elastic force, the slide rail 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 201 and an inner rail 202, and also includes a base 3, a first slide plate 4, a second slide plate 5, an elastic member 7 and a damping member 8; the base 3 is fixedly arranged on the inner wall of the rear end of the fixed slide rail 1, the first slide plate 4 is slidably arranged between the rear lower wall of the base 3 and the fixed slide rail 1, and the first slide plate 4 is arranged on the rear lower wall of the base 3, which does not affect the adjustment function and can also make it not easy to be damaged and shifted, so that The second slide 5 is slidably arranged at the front of the base 3, a receiving groove 301 is arranged at the side of the base 3, an elastic member 7 is arranged in the receiving groove 301, the second slide 5 is connected to the first slide 4 through the elastic member 7 so that it has elastic stress toward the first slide 4, a damping member 8 is arranged in the middle of the base 3, the base 3 is connected to the second slide 5 through the damping member 8, and an elastic adjustment mechanism is arranged on the base 3, and the elastic adjustment mechanism is used to adjust the relative distance between the first slide 4 and the second slide 5, thereby adjusting the elastic force of the elastic member 7. Preferably, the elastic member 7 is a tension spring. An elastic adjustment mechanism is arranged in the elastic force adjustable buffer, which can change the elastic force provided by adjusting the stroke of the elastic member 7, thereby adjusting the opening and closing elastic force of the slide rail, so that the user can open and close the drawer more conveniently and comfortably to meet the needs of different drawers.

[0019] like Figure 4-9As shown, the elastic adjustment mechanism includes an adjustment gear 6 and an anti-skid tooth groove 304, a through hole 302 is provided on the base 3, an adjustment portion 601 of the adjustment gear 6 is rotatably arranged in the through hole 302, the anti-skid tooth groove 304 is arranged on the lower wall of the base 3, the gear portion 602 of the adjustment gear 6 cooperates with the anti-skid tooth groove 304, the adjustment gear 6 has a linkage bar 603 that cooperates with the linkage hole 401 of the first slide 4, and the adjustment gear 6 is turned to adjust the position of the first slide 4 in the direction of the slide rail. The adjustment distance of the first slide 4 can be adaptively adjusted according to the elastic force of the elastic member 7, and is suitable for more types of elastic members.

[0020] It should be noted that the elastic adjustment mechanism in this embodiment adopts a method of cooperating the adjusting gear 6 with the anti-slip tooth groove 304, but the key function is to adjust the elastic force of the elastic member 7 and place the first slide 4 between the base 3 and the fixed slide rail 1 to ensure that the first slide 4 is not affected by other factors. Therefore, it is assumed that the adjusting gear 6 is replaced by a roller or the shape of the anti-slip tooth groove 304 is geometrically changed, etc., and adjustments are made on the base 3 to change the relative distance between the first slide 4 and the second slide 5. That is, for the simple changes made to the elastic adjustment mechanism in this embodiment, other producers, sellers or users only imitate this application with slight changes, which should be regarded as equivalent infringement.

[0021] like Figure 8 As shown, the damping member 8 includes a hydraulic cylinder 801 and a piston rod 802 . The hydraulic cylinder 801 is fixedly disposed on the base 3 . One end of the piston rod 802 is telescopically disposed in the hydraulic cylinder 801 , and the other end is connected to the second sliding plate 5 .

[0022] like Fig.10 and 11 As shown, the base 3 also includes a transmission member 9 and a hook 10. The front portion 302 of the base 3 is provided with a sliding groove 303. The transmission member 9 is swingably arranged in the second slide plate 5 and has a transmission column 901. The hook 10 is arranged on the inner wall of the inner rail 202. The upper end of the transmission column 901 is movably matched with the hook 10, and the lower end slides in the sliding groove 303. The sliding groove 303 has a locking position 3031, and the locking position 3031 is used to lock or unlock the second slide plate 5. The inner wall of the hook 10 has a recess 1001. When the upper end of the transmission column 901 is placed in the recess 1001, the transmission member 9 is deflected. When the transmission member 9 is deflected, the transmission column 901 falls into or out of the locking position 3031, and then the second slide plate 5 is correspondingly locked or unlocked on the base 3.

[0023] The specific working principle of the elastic adjustable buffer of the present invention is as follows: When the slide rail is in the closed state, the inner rail 202 is pulled outward, and the inner rail 202 drives the transmission member 9 to slide along the sliding groove 303 through the hook 10. The elastic member 7 generates resistance and the damping member 8 generates damping force until the transmission member 9 deflects and falls into the locking position 3031. The second slide plate 5 is locked on the base 3, the inner rail 202 is separated from the second slide plate 5, and the movable slide rail 2 can be pulled open.

[0024] When the slide rail is in the open state, the inner rail 202 is pushed, and the inner rail 202 causes the transmission member 9 to deflect and disengage from the locking position 3031 through the hook 10, the elastic member 7 generates elastic force, drives the second slide 5 to move, the damping member 8 generates damping force, and the slide rail slowly closes.

[0025] Embodiment 2: like Fig.12 As shown, this embodiment is a stable slide rail with adjustable rebound elastic force. The main structure is the same as that of the first embodiment, and the difference is that the size of the elastic member 7 and the damping member 8 is reduced, the stroke of the sliding groove 303 is shortened, and the rebound elastic force of the entire slide rail is reduced, which is suitable for smaller drawers.

[0026] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
