Description

Technical Field

[0001] This utility model relates to the field of refrigerator structure technology, and in particular to a connection structure for refrigerator drawer guide rails. Background Technology

[0002] In existing technologies, the assembly and fixation of the connecting rod and the sliding mechanisms on both sides on the metal guide rail generally relies on the fastening connection of multiple sets of screws. During the assembly process, the operator needs to tighten the screws at each connection point one by one. Not only is a large number of screws required, but due to the lack of an effective pre-positioning structure, the operator must manually guide the slide rail and connecting rod to complete the precise alignment of the screw holes before the screws can be installed and tightened. This traditional assembly method makes the assembly process redundant and complicated, prolongs the manual operation time, and results in low assembly efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a connection structure for refrigerator drawer slides, which has the advantage of efficient installation, thus overcoming the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A connection structure for a refrigerator drawer slide includes a slide rail and a connecting rod, characterized in that: it further includes a fixing component; the slide rail includes a first positioning hole, a second positioning hole, and a first protrusion, and the end of the slide rail is provided with a first bent portion; the fixing component includes a second protrusion, a positioning portion, a first cavity, a hook, and a protruding block;

[0006] The connecting rod has a second bend at its end, and the second bend has a first positioning post, which is adapted to the positioning part; the hook engages with the snap-fit ​​part, and the second protrusion is adapted to the first positioning hole.

[0007] The positioning part includes a positioning groove and a second positioning post. The second positioning post protrudes from the bottom surface of the positioning groove. The outer peripheral wall of the second positioning post is adapted to fit the second positioning hole. A positioning cavity is formed inside the second positioning post. The cavity wall is adapted to fit the outer peripheral wall of the first positioning post.

[0008] The connecting rod is provided with a groove, and the snap-fit ​​part is provided at the end of the groove. The snap-fit ​​part includes a cantilever and a snap-fit ​​block. There is a gap between the free end of the cantilever and the snap-fit ​​block. The snap hook extends into the gap and snaps onto the snap-fit ​​block.

[0009] The protruding block abuts against the end of the connecting rod.

[0010] The positioning part has an arc-shaped surface, which is used to abut against the refrigerator sliding mechanism.

[0011] The back of the fastener is provided with a second recess and a third recess.

[0012] The slide rail includes a first flange and a second flange, and a fixing plate is provided at the other end of the slide rail, with mounting holes provided on the fixing plate.

[0013] The above technical solution has the following beneficial effects:

[0014] To ensure efficient installation of the connecting rod, this invention pre-fixes the connecting rod and the two side fixing components during installation by using the second protrusion and the first positioning hole, as well as the first positioning post and the positioning part. Then, the connecting rod is connected by the snap-fit ​​of the hook and the snap-fit ​​part, achieving efficient installation of the guide rail. Simultaneously, the arc-shaped surface of the positioning part of the two side fixing components optimizes the contact structure with the refrigerator's sliding mechanism to reduce the friction area and increase the smoothness of sliding. This invention not only solves the problem of guide rail installation efficiency but also effectively improves the smoothness of product sliding, ultimately achieving a dual improvement in assembly efficiency and user experience. It is both practical and economical, facilitating large-scale production and market promotion of the product. Attached Figure Description

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] See Figures 1-4 As shown, this utility model discloses a connection structure for refrigerator drawer guide rails.

[0024] A connection structure for a refrigerator drawer slide includes a slide rail 1 and a connecting rod 2, characterized in that it further includes a fixing member 3. The slide rail 1 includes a first positioning hole 11, a second positioning hole 14, and a first protrusion 12. The end of the slide rail is provided with a first bending portion 13. The fixing member 3 includes a second protrusion 31, a positioning portion 32, a first cavity 33, a hook 34, and a protruding block 35. The end of the connecting rod is bent outward to form a second bending portion 23. The second bending portion 23 is provided with a first positioning post 24, which is adapted to the positioning portion 32. The hook 34 is engaged with the locking portion 22, and the second protrusion 31 is adapted to the first positioning hole 11.

[0025] The positioning part includes a positioning groove 321 and a second positioning post 322. The second positioning post 322 protrudes from the bottom surface of the positioning groove 321. The outer peripheral wall of the second positioning post 322 is adapted to fit the second positioning hole 14. A positioning cavity 3221 is formed inside the second positioning post 322. The cavity wall of the positioning cavity is adapted to fit the outer peripheral wall of the first positioning post 24.

[0026] The connecting rod 2 is provided with a groove 21, and the snap-fit ​​part 22 is provided at the end of the groove 21. The snap-fit ​​part 22 includes a cantilever 221 and a snap-fit ​​block 222. There is a gap between the free end of the cantilever 221 and the snap-fit ​​block 222. The snap hook 34 extends into the gap and snaps onto the snap-fit ​​block.

[0027] The protruding block 35 abuts against the end of the connecting rod.

[0028] The positioning part is provided with an arc-shaped surface 36, which is used to abut and cooperate with the refrigerator sliding mechanism.

[0029] The back of the fixing component is provided with a second recess 37 and a third recess 38. The third recess 38 is coaxially arranged with the axial holes of the first positioning post 24 and the second positioning post 322. During assembly, the screw passes through the third recess 38, the axial hole of the first positioning post and the axial hole of the second positioning post in sequence, and is locked by the screw to realize the detachable fixed connection of the slide rail, the connecting rod and the fixing component.

[0030] The slide rail includes a first flange 25 and a second flange 26. The other end of the slide rail is provided with a fixing plate 27, and the fixing plate is provided with mounting holes 28.

[0031] The working principle of this utility model is as follows: During assembly, the first positioning hole and the second protrusion engage with a snap-fit ​​mechanism, combined with the interlocking connection between the first positioning post and the second positioning post of the positioning part, quickly completing the pre-positioning and fixing of each component, laying a stable foundation for subsequent assembly. Then, utilizing the snap-fit ​​engagement between the hook and the connecting rod's engagement part, the hook passes through the gap between the free end of the cantilever and the locking block, and then snaps onto the locking block, achieving stable positioning of each component and improving the accuracy and stability of the assembly. Finally, the screws are tightened along the third concave cavity and the axial holes of the first and second positioning posts, completing the fixing of the slide rail, connecting rod, and fixing parts. Simultaneously, the positioning parts of the fixing parts on both sides adopt an optimized arc-shaped surface design, reducing the frictional contact area between the fixing parts and the mating parts, reducing the frictional resistance during the relative sliding process of the parts, and improving the smoothness of movement.
