Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigerators, in particular to a drawer structure and a refrigerator. Background Art
[0002] For high-end refrigerators, the guide rails used for drawer opening and closing are generally multi-section metal guide rails. The assembly method of the metal guide rails and the drawer generally adopts snap interference fit for fixation. There are two problems in the installation of such an installation structure:
[0003] 1. When pressing the drawer for snap fixation, if the force is not applied vertically downward, on the one hand, the incomplete snap connection may be caused due to insufficient vertical component force. On the other hand, the component force along the horizontal direction will drive the guide rail to rebound (when installing the drawer, the guide rail must be pulled to the maximum stroke), affecting the assembly efficiency;
[0004] 2. When the drawer is not completely aligned with the guide rail clamping posts on both sides, pressing the drawer downward will result in a phenomenon that one side has been assembled while the other side has not been assembled, resulting in assembly failure. It is necessary to disassemble the drawer and reinstall it, affecting the assembly efficiency. Summary of the Utility Model
[0005] Based on this, in view of the problems of high assembly difficulty and low assembly efficiency existing in the current snap interference fit between the metal guide rail and the drawer, it is necessary to provide a drawer structure and a refrigerator with lower assembly difficulty and higher assembly efficiency.
[0006] The present application first provides a drawer structure, including a guide rail and a drawer. An upwardly extending guide post is fixed on the guide rail, and a card slot with an upward opening is further formed on the guide rail. A guide post hole is formed through the drawer, and a snap that can be snap-connected with the card slot is fixed on the drawer;
[0007] When the snap is snap-connected with the card slot, the guide post penetrates through the guide post hole, and there is a gap between each side surface of the guide post and the corresponding side wall of the guide post hole.
[0008] In one embodiment, the guide post is in an I shape.
[0009] In one embodiment, the length of the guide post along the X-axis direction is less than the length of the guide post hole along this direction, and the difference between the two ranges from 3 mm to 5 mm.
[0010] In one embodiment, when the snap is snap-connected with the card slot, the two side surfaces of the snap along the X-axis direction are in close contact with the inner walls of the corresponding sides of the card slot.
[0011] In one embodiment, the length of the guide post along the Y-axis direction is less than the length of the guide post hole along this direction, and the difference between the two ranges from 0.5 mm to 1.5 mm.
[0012] In one embodiment, when the buckle is snap-fitted with the card slot, the two clearance distances between the guide post and the guide post hole in the X-axis direction are the same, and the two clearance distances in the Y-axis direction are also the same.
[0013] In one embodiment, the bottom edge of the guide post hole has a chamfer.
[0014] In one embodiment, a plurality of the buckles are fixedly provided at the bottom of the drawer.
[0015] In one embodiment, two of the buckles are fixedly provided at the bottom of the drawer, and the two buckles are symmetrically fixed on both sides of the guide post hole in the X-axis direction.
[0016] The second aspect of the present application provides a refrigerator, including the above-mentioned drawer structure.
[0017] For the above-mentioned drawer structure, by providing the guide post and the guide post hole, the assembly process between the drawer and the guide rail is adjusted to first complete the pre-fixation between the guide post and the guide post hole, and then complete the fine-tuning snap-fitting fixation between the buckle and the card slot, effectively reducing the assembly difficulty between the drawer and the guide rail and improving the assembly efficiency.
[0018] Specifically, since there are gaps between each side surface of the guide post and the corresponding side wall of the guide post hole, during the pre-fixation process, the operator does not need to press the drawer downward forcefully, effectively preventing the situation of the guide rail rebounding due to excessive force; after the pre-fixation is completed, the existence of the gap ensures that the drawer can be slightly adjusted relative to the guide rail, and the operator can align the card slot with the buckle by slightly translating the drawer, so that the buckle can be easily inserted into the card slot.

[0030] Currently, the common assembly method between the metal guide rail and the drawer is to use snap-in interference fixation. Through a columnar structure that protrudes locally on the guide rail and a notch structure designed on the reinforcing rib on the side of the drawer for assembly. Generally, the size of the notch is 0.15 mm - 0.2 mm smaller than the maximum distance of the columnar structure on one side, so as to ensure that the drawer and the guide rail can be assembled while minimizing the shaking of the drawer (the single-sided gap is small and the movable space of the drawer is small);
[0031] Specifically, the assembly process of the drawer and the guide rail under the original structure is as follows: First, pull the guide rail to the maximum stroke, then place the drawer obliquely downward on the guide rail, first fix the hook on the tail side of the drawer and the tail side of the guide rail, and finally, it is necessary to align the notch on the side of the drawer with the position of the columnar structure on the guide rail and press the drawer downward to complete the interference fit between the drawer and the guide rail;
[0032] During the above assembly process, firstly, it is difficult to accurately find the corresponding positions of the notch on the drawer and the columnar structure on the guide rail; secondly, when pressing the drawer with a relatively large force, there is a certain probability that the snap-fit assembly cannot be completed, resulting in the guide rail rebounding and affecting the assembly efficiency.
[0033] Please refer to Figures 1 to 4 As shown in the figure, the present application first provides a drawer structure, including a guide rail 10 and a drawer 20. A guide post 11 extending upward is fixed on the guide rail 10, and a card slot 12 with an upward opening is also formed on the guide rail 10. A guide post hole 21 is formed through the drawer 20, and a snap 22 capable of being engaged with the card slot 12 is also fixed on the drawer 20; when the snap 22 is engaged with the card slot 12, the guide post 11 passes through the guide post hole 21, and there are gaps between each side surface of the guide post 11 and the corresponding side wall of the guide post hole 21.
[0034] In this application, by providing the guide posts 11 and the guide post holes 21, the assembly process between the drawer 20 and the guide rail 10 is adjusted to first complete the pre-fixation between the guide posts 11 and the guide post holes 21, and then complete the fine-tuning snap-fixation between the snap catches 22 and the card slots 12, effectively reducing the assembly difficulty between the drawer 20 and the guide rail 10 and improving the assembly efficiency.
[0035] Specifically, since there are gaps between the respective sides of the guide posts 11 and the corresponding side walls of the guide post holes 21, during the pre-fixation process, the operator does not need to press down on the drawer 20 forcefully, effectively preventing the situation where the guide rail 10 rebounds due to excessive force.
[0036] After the pre-fixation is completed, the existence of the gaps ensures that the drawer 20 can be slightly adjusted relative to the guide rail 10. The operator can align the card slots 12 with the snap catches 22 by slightly translating the drawer 20, and thus can easily insert the snap catches 22 into the card slots 12.
[0037] In some other embodiments, the positions of the card slots 12 and the snap catches 22, and the guide posts 11 and the guide post holes 21 can also be exchanged with each other. For example, the guide post holes 21 can be provided on the guide rail 10, and the guide posts 11 can be provided at the bottom of the drawer 20, etc., as long as pre-fixation can be carried out first and then snap-fixation can be carried out.
[0038] Please refer to Figures 1 to 4 As shown, in some embodiments, the guide posts 11 are in an I shape. Compared with the existing V-shaped structure, the guide posts 11 and the guide post holes 21 are in a clearance fit, so as to meet the requirements of pre-fixation.
[0039] Please refer to Figure 4 As shown, for the convenience of understanding, in this application, the length direction of the guide rail 10 is defined as the X-axis direction, and the width direction of the guide rail 10 is defined as the Y-axis direction.
[0040] Please refer to Figures 1 to 4 As shown, in some embodiments, the length of the guide posts 11 in the X-axis direction is less than the length of the guide post holes 21 in this direction, and the difference range between the two is 3 mm to 5 mm.
[0041] The above difference range is the fine-tuning range of the drawer 20 relative to the guide rail 10 in the X-axis direction after the pre-fixation is completed.
[0042] It is not difficult to understand that if the difference range is small, it will be difficult for the operator to accurately find the corresponding positions between the guide posts 11 and the guide post holes 21, resulting in difficult pre-fixation operations. On the contrary, if the difference range is large, it will be difficult for the operator to fine-tune to make the snap catches 22 correspond to the card slots 12 after the pre-fixation is completed, which will also affect the assembly difficulty.
[0043] By controlling the difference range within 3 mm to 5 mm, the difficulty of pre-fixing and fine-tuning the snap connection can be balanced, ensuring that the operator can complete the installation between the drawer 20 and the guide rail 10 more easily and efficiently.
[0044] Preferably, the difference between the length of the guide post 11 in the X-axis direction and the length of the guide post hole 21 in this direction is 4 mm.
[0045] Please refer to Figures 1 to 4 As shown, in some embodiments, when the buckle 22 is snap-connected to the card slot 12, the two sides of the buckle 22 in the X-axis direction are in close contact with the inner walls of the corresponding sides of the card slot 12.
[0046] Compared with the traditional interference structure of the buckle, in order to reduce the assembly difficulty, a gap of 0.15 mm to 0.2 mm needs to be reserved. In this application, the snap connection of the buckle 22 is carried out after the pre-fixing is completed, and the fine-tuning snap connection can be easily completed without reserving a gap. While reducing the assembly difficulty, the shaking of the drawer 20 after installation is reduced.
[0047] Please refer to Figures 1 to 4 As shown, in some embodiments, the length of the guide post 11 in the Y-axis direction is less than the length of the guide post hole 21 in this direction, and the difference range between the two is 0.5 mm to 1.5 mm.
[0048] Similarly, by controlling the difference range within 0.5 mm to 1.5 mm, the difficulty of pre-fixing and fine-tuning the snap connection can be balanced, ensuring that the operator can complete the installation between the drawer 20 and the guide rail 10 more easily and efficiently.
[0049] Preferably, the difference between the length of the guide post 11 in the Y-axis direction and the length of the guide post hole 21 in this direction is 1 mm.
[0050] In some embodiments, the depth of the card slot 12 is 2 mm, so that when the buckle 22 is inserted into the card slot 12, the drawer 20 will sink significantly, so that the operator can perceive whether the snap connection is in place, further reducing the assembly difficulty.
[0051] Please refer to Figures 1 to 4 As shown, in some embodiments, when the buckle 22 is snap-connected to the card slot 12, the two gap spacings between the guide post 11 and the guide post hole 21 in the X-axis direction are the same, and the two gap spacings in the Y-axis direction are also the same, so as to reduce the assembly difficulty of the two steps of pre-fixing and fine-tuning the snap connection.
[0052] Please refer to Figures 1 to 4 As shown, in some embodiments, the bottom edge of the guide post hole 21 has a chamfer to play a guiding role, facilitating the insertion of the guide post 11 into the guide post hole 21 during the pre-fixing process, and further reducing the assembly difficulty.
[0053] In some embodiments, a plurality of buckles 22 are fixedly provided at the bottom of the drawer 20. Preferably, please refer to Figures 1 to 4 As shown, in some embodiments, two buckles 22 are fixedly provided at the bottom of the drawer 20, and the two buckles 22 are symmetrically fixed on both sides of the guide post hole 21 in the X-axis direction to ensure reliable assembly.
[0054] The second aspect of the present application provides a refrigerator, including the above-mentioned drawer structure.
[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0056] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
