[0039] See also Figures 1 to 8 In order to solve the above technical problems, the utility model proposes a furniture slide rail anti-sinking support structure, including a slide rail assembly 1 and an anti-sinking support assembly 2:

[0040] The slide rail assembly 1 includes a fixed rail 11 and a movable rail 12, and the movable rail 12 is slidably connected to the fixed rail 11; the fixed rail 11 includes a fixed bottom plate 111, and a mounting hole 1111 is formed at the front end of the fixed bottom plate 111, and the mounting hole 1111 is used to install the anti-sinking support assembly 2;

[0041] The anti-sinking support assembly 2 includes a fixed seat 21 and a rolling element 22. The rolling element 22 is rotatably disposed on the fixed seat 21, and the rolling element 22 is located below the movable rail 12.

[0042] The fixing seat 21 includes a fixing seat body 210, a buckle 211 and a clamping block 212. The buckle 211 includes a fixing portion 2111, an elastic portion 2112 and a clamping portion 2113. The fixing portion 2111 is fixedly connected to the side wall of the fixing seat body 210. One end of the elastic portion 2112 is connected to the end of the fixing portion 2111 away from the fixing seat body 210. The other end of the elastic portion 2112 extends downward and is connected to the clamping portion 2113. The lower surface of the fixing portion 2111 abuts against the upper surface of the fixing base plate 111, and the clamping portion 2113 extends into the mounting hole 1111 and abuts against the lower surface of the fixing base plate 111, so that the fixing seat 21 can be detachably clamped in the mounting hole 1111; the side wall of the fixing seat body 210 opposite to the fixing portion 2111 is also provided with a protruding clamping block 212, and the lower surface of the clamping block 212 abuts against the upper surface of the fixing base plate 111.

[0043] By opening the mounting hole 1111 at the front end of the fixed base plate 111 and setting a snap-fit ​​piece 211 on the side wall of the fixed seat 21, during installation, the fixed seat 21 is snapped into the mounting hole 1111 from top to bottom, and the elastic part 2112 of the snap-fit ​​piece 211 is squeezed so that the snap-fit ​​part 2113 passes through the mounting hole 1111 and abuts against the lower surface of the fixed base plate 111, thereby realizing the installation of the fixed seat 21 on the fixed base plate 111. At the same time, a protruding block 212 is provided on the side wall of the fixing seat 21, so that the lower surface of the block 212 after installation is abutted against the upper surface of the fixing base plate 111, and the block 212 plays a role of balance and support, which can prevent the fixing seat 21 from shifting in the height direction; the installation process of the utility model is simple and reliable, and the installation can be completed by manual force, or it can be automatically installed by a machine. The installation process does not need to rely on welding equipment, which can reduce the installation and production costs and improve the installation efficiency and production efficiency; when disassembling, a flat-blade screwdriver or other applicable tools can be used to push the clamping part 2113 from the bottom of the mounting hole 1111 until it does not abut against the lower surface of the fixing base plate 111, so that the fixing seat 21 falls off from the mounting hole 1111. The disassembly method of the utility model is simple, and the anti-sinking support assembly 2 can be repeatedly disassembled and assembled for multiple times, which is convenient for replacement and maintenance, and effectively solves the problems of cumbersome installation and inflexible disassembly and replacement of the furniture slide rail anti-sinking support structure, low production efficiency and high production cost.

[0044] To further illustrate, when installing the anti-sinking support assembly 2, the anti-sinking support assembly 2 can be first installed on the fixed rail 11, and then the fixed rail 11 and the movable rail 12 can be assembled. Alternatively, the anti-sinking support assembly 2 and the fixed rail 11 can be assembled after the slide rail assembly 1 is assembled. The installation method of the utility model is not limited by site and time, and effectively improves the flexibility of installation.

[0045] By placing the movable rail 12 above the rolling element 22, when the movable rail 12 is pulled out with a light load, the movable rail 12 does not deform or sag, the rolling element 22 does not contact the movable rail 12, the anti-sinking support assembly 2 does not participate in the work, and the slide rail assembly 1 operates normally. When the movable rail 12 is pulled out with a heavy load, the movable rail 12 will deform and sag and be supported on the rolling element 22. Under the action of friction, the rolling element 22 supports the movable rail 12 and rotates along with it. The rolling element 22 can support the sliding of the movable rail 12 to prevent the movable rail 12 from sinking and deforming when the load is heavy. Since the anti-sinking support assembly 2 does not participate in the work when the movable rail 12 is lightly loaded, it is beneficial to extend the service life of the anti-sinking support assembly 2.

[0046] Another embodiment of the present invention is shown in Fig.12 and Fig.13 The slide rail assembly 1 can be set as a two-section slide rail, in which case the number of the movable rail 12 is one; the slide rail assembly 1 can also be set as a three-section slide rail, in which case the number of the movable rails 12 is two, specifically, the movable rail 12 includes an upper rail 121 and a middle rail 122, the upper rail 121 and the middle rail 122 are slidably connected via an upper roller frame 13, and the middle rail 122 and the fixed rail 11 are slidably connected via a lower roller frame 14; and the rolling element 22 is placed below the upper rail 121. The furniture slide rail anti-sinking support structure of the utility model can be applied to a two-section slide rail or a three-section slide rail, and has strong applicability and versatility.

[0047] See also Figure 2 , Figure 5 and Figure 8 , further explained, the fixed base plate 111 is connected with a clamping block 112 on one side of the mounting hole 1111, and the clamping block 112 is protruded toward the direction of the mounting hole 1111, and a clamping cavity 113 for the clamping portion 2113 to be clamped is formed between the clamping block 112 and the fixed base plate 111, and the clamping cavity 113 is communicated with the mounting hole 1111; the clamping portion 2113 is protruded from the elastic portion 2112 toward an end away from the fixing seat body 210, and the clamping portion 2113 extends into the clamping cavity 113 and abuts against the lower end surface of the clamping block 112.

[0048] By setting the snap-in block 112, when installing the fixing seat 21, the snap-in member 211 can be quickly placed in the direction of the snap-in block 112, which helps to quickly snap-in and install the fixing seat 21 to the fixing base plate 111, thereby improving the efficiency of installation; the snap-in block 112 is protruded in the direction of the mounting hole 1111, so as to form a snap-in cavity 113 between the fixing base plate 111 for snapping with the snap-in portion 2113, and the setting of the snap-in cavity 113 helps to hide the snap-in portion 2113 in the mounting hole 1111.

[0049] See also Figure 8 , further illustrating that the lower end surface of the clamping portion 2113 is flush with the lower end surface of the fixed base plate 111.

[0050] Since the fixed rail 11 also needs to be fixed to an external structure (such as furniture) during application, the clamping portion 2113 can be hidden in the mounting hole 1111 by making the lower end surface of the clamping portion 2113 flush with the lower end surface of the fixed base plate 111, so that the entire furniture slide rail anti-sinking support structure is more compact, and can effectively avoid interference between the fixed seat 21 and other external structures, thereby avoiding affecting the stability of the slide rail assembly 1.

[0051] See also Figure 8 what Fig. 9 , further explained, the side of the clamping block 112 facing the mounting hole 1111 is provided with an introduction slope 1121, and the introduction slope 1121 is inclined downward toward the mounting hole 1111; the side of the clamping portion 2113 facing the clamping block 112 is provided with an insertion slope 21131, and the insertion slope 21131 cooperates with the introduction slope 1121.

[0052] The setting of the introduction slope 1121 and the insertion slope 21131 is conducive to inserting the snap-fit ​​portion 2113 downward along the introduction slope 1121 into the snap-fit ​​cavity 113, which can quickly complete the snap-fit ​​installation between the fixing seat 21 and the fixing base plate 111, thereby improving the installation efficiency.

[0053] See also Figure 6 to Figure 7 , further explained, the two side walls of the fixing seat body 210 adjacent to the fixing portion 2111 are respectively provided with the blocking blocks 212 .

[0054] By respectively arranging the clamping blocks 212 on the two side walls of the fixing seat body 210 adjacent to the fixing portion 2111 , the fixing seat 21 is balanced, thereby further improving the stability and load-bearing capacity of the fixing seat 21 .

[0055] See also Figures 5 to 8 , further explained, the fixing seat 21 also includes a flange 213, the bottom end of the fixing seat body 210 is extended downward to have the flange 213, the flange 213 is placed in the mounting hole 1111, and the flange 213 is abutted against the inner wall of the mounting hole 1111.

[0056] By providing the flange 213 , the flange 213 is placed in the mounting hole 1111 and abuts against the inner wall of the mounting hole 1111 , thereby effectively preventing the fixing seat 21 from shifting in the horizontal direction, thereby improving the stability of the fixing seat 21 .

[0057] See also Figures 5 to 8, further explained, the number of the flanges 213 is two, the flanges 213 are connected to the two ends of the fixing seat body 210, the two flanges 213 are symmetrically arranged relative to the fixing seat body 210, and the two flanges 213 and the snap-fitting member 211 are respectively arranged on different side walls of the fixing seat 21.

[0058] By providing two symmetrical flanges 213 , the fixing base 21 can be further prevented from shifting in the horizontal direction, thereby improving the stability of the fixing base 21 .

[0059] See also Figure 6 to Figure 7 , further explained, the anti-sinking support assembly 2 also includes a pin shaft 23 , the fixing seat body 210 is provided with a cavity 214 , and the rolling element 22 is rotatably installed in the cavity 214 through the pin shaft 23 .

[0060] The rolling element 22 is rotatably mounted in the cavity 214 via the pin shaft 23 , so that the rolling element 22 can be limited to move in the cavity 214 and is not easily dropped from the fixing seat 21 , which helps to improve the stability of the anti-sinking support assembly 2 .

[0061] Further, the cavity 214 is a structure with upper and lower openings, which can significantly reduce the weight of the fixing seat 21, save materials for making the fixing seat 21, help reduce production costs, and achieve a lightweight effect; secondly, when the rolling element 22 needs to be removed, the cavity 214 is designed to be a structure with upper and lower openings, so that the operator can remove the rolling element 22 from the bottom to the top of the cavity 214, which facilitates the removal of the rolling element 22; at the same time, it also helps air circulation, which can effectively prevent the interior of the fixing seat 21 from mold or rust due to moisture, thereby extending the service life.

[0062] Specifically, optionally, the rolling element 22 may be a roller or a ball bearing.

[0063] To further illustrate, the material of the fixing base 21 can be metal or plastic.

[0064] See also Figure 6 and Fig.10 , further explained, the opposite side walls of the fixing seat body 210 are respectively provided with groove openings 215, the pin shaft 23 passes through the center of the rolling element 22, the rolling element 22 is rotatably connected to the pin shaft 23, and the two ends of the pin shaft 23 are respectively clamped in the groove openings 215.

[0065] The rolling element 22 and the fixing seat 21 are connected by the pin 23, and the two ends of the pin 23 are respectively clamped in the groove 215. The pin 23, the rolling element 22 and the fixing seat 21 can be assembled manually without the need for additional assembly equipment, and the assembly method is simple. It should be noted that the inner diameter of the opening end of the groove 215 is smaller than the diameter of the pin 23. Specifically, when an external force is applied to the pin 23, the pin 23 can be clamped into the groove 215. After installation, since the inner diameter of the opening end of the groove 215 is smaller than the diameter of the pin 23, the pin 23 can be prevented from falling off from the opening of the groove 215 without applying an external force, thereby effectively improving the structural stability of the anti-sinking support assembly 2.

[0066] See also Fig.10 and Fig.11 , further explained, a square cup head 231 is provided at one end of the pin shaft 23, and the side length of the square cup head 231 is greater than the diameter length of the pin shaft 23; one of the groove openings 215 and the block 212 are respectively provided on the same side wall of the fixing seat body 210, and a limiting groove 216 is further provided between the groove opening 215 and the block 212, and the square cup head 231 is embedded in the limiting groove 216.

[0067] Specifically, the shape of the limiting groove 216 matches the shape of the square cup head 231. The groove core position height of the limiting groove 216 is lower than the position height of the groove opening 215, and at the same time, the groove core position height of the limiting groove 216 is also lower than the position height of the upper end surface of the clamping block 212.

[0068] By setting the block 212, a square cup head 231 is set at one end of the pin shaft 23. When assembling the anti-sinking support assembly 2, the pin shaft 23 is first passed through the center of the rolling element 22, and then the two ends of the pin shaft 23 are pressed into the two groove openings 215 respectively, and the square cup head 231 is embedded in the limiting groove 216. Since the groove core position height of the limiting groove 216 is lower than the position height of the groove opening 215 and the position height of the upper end surface of the block 212, the displacement of the pin shaft 23 in the axial direction of the rolling element 22 can be limited, thereby preventing the pin shaft 23 from falling off from the rolling element 22, and improving the stability and reliability of the anti-sinking support assembly 2.

[0069] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
