[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Please refer to them. Figures 1 to 8 The image shows one embodiment of this utility model.
[0025] It should be understood that, unless otherwise expressly specified and limited, in this application, the terms “up,” “down,” “front,” “back,” “left,” “right,” etc., indicate the orientation or positional relationship based on the user’s facing side of the door of the household appliance being in front, and are used only for ease of description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed or operated in a specific orientation.
[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means two or more, and at least two.
[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "set", "connect", "connect", "fixed" and other such terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part.
[0028] This utility model provides a refrigeration device. Figures 1 to 8 An embodiment according to the present invention is shown.
[0029] In this embodiment, the refrigeration device is a refrigerator. It should be noted that although this utility model is described using a refrigerator as an example, it is not limited to this and can also be other devices that can provide refrigeration function.
[0030] like Figures 1 to 2 As shown, in general, refrigeration equipment opens and closes the drawer by manually pulling out or pushing out the slide rail 10 installed between the drawer and the inner wall 11 of the equipment. Two sets of slide rails 10 are symmetrically installed on both sides of the drawer, and the slide rails 10 are connected to the inner wall 11 of the equipment through the slide rail bracket 2.
[0031] Therefore, if the sliding rail bracket 2 is misaligned or inaccurately positioned in relation to the inner wall 11, it will cause the entire sliding rail and drawer to become skewed. To ensure accurate positioning and installation of the drawer's two side sliding rails 10 with the refrigeration equipment's inner wall, the solution of this utility model is specifically described as follows:
[0032] The refrigeration equipment includes an inner liner 1, which includes a first side wall 111, a second side wall 112, and a third side wall 113. The first side wall 111, the second side wall 112, and the third side wall 113 form a cavity with an opening facing the door of the refrigeration equipment. The third side wall 113 faces the door of the refrigeration equipment, and the first side wall 111 and the second side wall 112 are arranged opposite to each other and are respectively connected to the left and right sides of the third side wall 113.
[0033] The refrigeration equipment includes a slide rail bracket 2 connected to the inner liner side wall 11, the slide rail bracket 2 being used to connect the slide rail 10 to the inner liner side wall 11 of the refrigeration equipment.
[0034] The slide rail bracket 2 is disposed opposite to the first side wall 111 and the second side wall 112. Of course, in some other embodiments, the slide rail bracket 2 can also be installed on one side wall of the inner liner 1 or other positions of the inner liner 1 where slide rails need to be installed, depending on actual needs. This embodiment takes the slide rail bracket 2 disposed on the first side wall 111 as an example for specific explanation.
[0035] In this embodiment, the slide rail bracket 2 extends along the front-to-back direction of the inner liner 1 on the first side wall 111 of the inner liner 1, and is consistent with the movement direction of the slide rail 10 and the drawer being pulled out or pushed in, which facilitates the installation of the slide rail and improves the stability of the slide rail movement.
[0036] Reference Figures 3 to 7 The slide rail bracket 2 includes a bracket body 3, a positioning structure 4 for positioning the bracket body 3 on the inner liner side wall 11, and a fixing structure 5 for fixing the bracket body 3 on the inner liner side wall 11. The inner liner side wall 11 is provided with an installation part 6 that cooperates with the slide rail bracket 2.
[0037] During installation, the positioning structure 4 cooperates with the mounting part 6 to accurately position the installation position of the slide rail bracket 2. After positioning, the slide rail bracket 2 can be fixed to the inner liner side wall 11 by the cooperation of the fixing structure and the mounting part 6. The operation is simple and easy.
[0038] Specifically, the positioning structure 4 includes a pair of spaced positioning posts 41, and the mounting part 6 includes a pair of positioning protrusions 61 that cooperate with the positioning posts 41. The positioning protrusions 61 protrude outward toward the outer side of the inner liner 1 and have a receiving cavity 62 with an opening facing the inner side of the inner liner 1. The positioning posts 41 are fitted into the receiving cavity 62.
[0039] During installation, simply insert the pair of positioning posts 41 into the corresponding accommodating cavity 62 of the positioning protrusion 61. The positioning posts 41 can fit into the accommodating cavity 62 and fit completely against the positioning protrusion 61. By setting two positioning posts 41, the position of the entire slide rail bracket 2 on the inner liner side wall 11 along the vertical and horizontal directions can be determined, so that the entire slide rail bracket 2 is accurately positioned with the inner liner 1 of the refrigeration equipment. This positioning method is simple and requires no measurement or calibration.
[0040] At the same time, when the positioning post 41 is inserted into the corresponding positioning protrusion 61, the positioning protrusion 61 can also provide a certain support force for the slide rail bracket 2, so that the slide rail bracket 2 and the inner liner side wall 11 are stably attached, completing the initial pre-fixation and providing convenience for subsequent fastening connection.
[0041] In this embodiment, the pair of spaced positioning posts 41 are respectively located at both ends near the slide rail bracket 2, and the pair of positioning protrusions 61 are respectively located at corresponding positions in cooperation with the positioning posts 41. This increases the spacing between the two positioning posts 41, ensuring the most accurate installation position of the entire slide rail bracket 2 and preventing one end from tilting upwards or downwards.
[0042] The positioning post 41 has a top wall 411 and an outer wall 412, and the receiving cavity 62 includes a bottom wall 621 that cooperates to adsorb the top wall 411 and a peripheral wall 622 that fits against the outer wall 412.
[0043] The bottom wall 621 of the positioning protrusion 61 can be made of rubber or other absorbent material, which can work together to apply a certain adsorption to the positioning post 41 inserted into the receiving cavity 62, ensuring that the positioning post 41 and the positioning protrusion 61 are completely fitted together and preventing them from falling off.
[0044] The positioning post 41 is cylindrical and extends from the bracket body 3 toward the positioning protrusion 61. Correspondingly, the positioning protrusion 61 is hollow cylindrical and extends outward from the plane of the inner liner sidewall 11, so that the positioning post 41 and the positioning protrusion 61 can be better matched and connected.
[0045] In this embodiment, the positioning post 41 is cylindrical, and the positioning protrusion 61 cooperates with the positioning post 41 to form a hollow cylinder.
[0046] Of course, in some other embodiments, the positioning post 41 can also be set to other column shapes, as long as the positioning post 41 and the positioning protrusion 61 fit together completely.
[0047] The positioning structure 4 also has two claws 42 respectively disposed at both ends of the slide rail bracket 2, and the mounting part 6 is provided with two slots 63 that penetrate the inner liner sidewall 11. The two claws 42 and the two slots 63 respectively engage and engage.
[0048] The pair of spaced positioning posts 41 are located between the two claws 42, respectively close to one of the claws 42. That is, the two claws 42 are respectively located at both ends of the slide rail bracket 2, on the outside of the positioning posts 41, to enhance the stability of the slide rail bracket 2 in contact with the inner liner side wall 11, prevent the slide rail from shifting, and avoid uneven drawer doors caused by inaccurate slide rail positioning.
[0049] Specifically, the two claws 42 include a first claw 421 and a second claw 422. The first claw 421 is vertically connected to the bracket body 3 and extends through the slot 63 to the outside of the inner liner 1.
[0050] In this embodiment, the first claw 421 extends vertically from the vertical support body 3 toward the outside of the inner liner 1.
[0051] The second claw 422 has a first locking edge 4221 that is perpendicularly connected to the bracket body 3, and a second locking edge 4222 that is connected to the first locking edge 4221 and extends to the outside of the inner liner 1. The second locking edge 4222 extends in a direction away from the positioning post 41. After the first claw 421 and the second claw 422 are engaged, the second claw 422 can simultaneously hold the slot 63 of the inner liner 1 in conjunction with the limiting of the first claw 421, preventing the slide rail bracket 2 from moving relative to the inner liner sidewall 11.
[0052] In this embodiment, the first claw 421 is located at the end of the slide rail bracket 2 near the front side of the inner liner 1, the second claw 422 is located at the end of the slide rail bracket 2 near the rear side of the inner liner 1, and the second claw edge 4222 extends toward the rear side of the inner liner 1.
[0053] The first locking edge 4221 passes through the locking groove 63, and the second locking edge 4222 is arc-shaped with its inner arc surface facing the inner liner sidewall 11.
[0054] In this embodiment, the middle portion of the second retaining edge 4222 bends towards the inner liner sidewall 11. A first gap 7 is formed between the second retaining edge 4222 and the inner liner sidewall 11, as shown in the figure. Figure 4 and Figure 8 As shown, the opening of the first gap 7 is relatively wide, which makes it easy to insert the second claw 422 into the slot 63 during installation. The second claw edge 4222 extends to the outside of the inner liner 1. The inside of the first gap 7 is relatively narrow, which can abut against the side wall 11 of the inner liner. This is beneficial for pressing the second claw edge 4222 tightly onto the inner liner 1 after installation, thereby preventing the slide rail bracket 2 from moving or falling off relative to the side wall 11 of the inner liner.
[0055] The mounting part 6 has a fixing hole 64 that passes through the inner liner sidewall 11. The fixing structure 5 includes a through hole 51 that cooperates with the fixing hole 64 and a fixing member 52 that passes through the through hole 51 and the fixing hole 64 to fasten the slide rail bracket 2 to the inner liner sidewall 11.
[0056] In this embodiment, the connection is fastened by screws passing through the fixing hole 64. Of course, in some other embodiments, the slide rail bracket 2 can also be fastened to the inner liner side wall 11 by welding or riveting.
[0057] In this embodiment, the specific installation method of the slide rail bracket is as follows: When the slide rail bracket 2 is positioned and installed on the inner liner side wall 11, the first claw 421 and the second claw 422 are first slidably inserted into the corresponding slot 63; the positioning post 41 is inserted into the receiving cavity 62 of the positioning protrusion 61, and the positioning post 41 is pushed to the bottom of the inner liner, so that the bottom wall 621 of the positioning protrusion 61 adheres to the top wall 411 of the positioning post 41, and the positioning post 41 and the positioning protrusion 61 are completely fitted together;
[0058] At this time, the two claws 42 and the two slots 63 are also engaged and locked in place, the slide rail bracket 2 is positioned and pre-fixed to the inner liner side wall 11, and then the fastener 52 passes through and is fastened to the fixing hole 64, so that the slide rail bracket 2 can be fastened to the inner liner side wall 11, and the installation procedure is completed.
[0059] In summary, the refrigeration equipment provided by this utility model achieves precise positioning of the slide rail and the inner liner by adsorbing and fitting a pair of positioning posts spaced apart on the slide rail bracket with corresponding positioning protrusions on the inner liner. This facilitates installation and fixation, prevents slide rail misalignment, avoids uneven drawer doors caused by inaccurate slide rail positioning, better ensures the performance of the drawer slide rail, extends the service life of the drawer, simplifies the installation and positioning method, and improves the efficiency of slide rail installation.
