Description

Technical Field

[0001] The utility model relates to a drawer installation structure and refrigeration equipment comprising the drawer installation structure. Background Art

[0002] As a large appliance with high frequency of daily use, the refrigerator has developed into a larger and larger space, and more and more categories can be placed. There are too many ingredients stored in the refrigerator. French refrigerators are popular in the market because their push-pull door body conforms to people's living habits. French refrigerators are generally composed of drawer doors. The refrigerator drawer door is one of the important components of French refrigerators. Improving the pull-out stability of the refrigerator drawer door helps to improve the performance stability and user experience of the refrigerator. In the prior art, the refrigerator drawer door is mainly sealed by the suction force of the guide rail and the door seal. The guide rail is installed on the box body, and the door body support frame is installed on the guide rail. The door body support frame cooperates with the guide rail to assemble the drawer door and the drawer together. Due to the low precision of the punching position of the fixed guide rail on the drawer door, the error is relatively large, which will cause the drawer door spacing deviation of the same product to be large, resulting in the drawer door tilting and the drawer sealing problem, which seriously affects the product appearance, energy consumption and reliability. In addition, the drawer door spacing of different products varies greatly, and the process is difficult to control. At present, refrigerators with drawer door bodies on the market usually realize the movement of the drawer door body through guide rails, and the guide rails are generally installed on the box after foaming. The box needs to be punched, and the punching precision is not high. Therefore, the accuracy of the guide rail assembly is very important, which directly affects the performance of the drawer door during the push-pull process, and whether the door is installed flush in the up-down and left-right directions.

[0003] At present, in order to improve the pulling and pulling stability of refrigerator drawer doors, a synchronization rod structure is added to improve it. Specifically, the synchronization rod structure mainly includes synchronization rods, gears, racks and other structures. In the existing synchronization rod structure, the gears rotate back and forth in a vertical plane, and the gears and drawer doors are assembled together, which requires very high assembly skills of workers and can easily cause misalignment of gears and racks. In other words, the tooth grooves meshed by the first gear and the first rack do not correspond to the tooth grooves meshed by the second gear and the second rack, and the projections in the vertical plane extending front and back do not overlap. If misalignment occurs, the existing structure is not convenient for adjusting the gears and racks, affecting the transmission between the gears and the racks, thereby affecting the pulling and pulling of the refrigerator drawer doors, especially causing jamming during the pulling and pulling process, the door cannot be installed in place, resulting in cold leakage, and freezing and icing, affecting the user experience.

[0049] like Figure 1-4 As shown, this embodiment discloses a refrigeration device, including a drawer installation structure 1000 , a cabinet 3000 , a drawer door 4000 , a first slide rail assembly 2001 , and a second slide rail assembly 2002 .

[0050] The drawer mounting structure 1000 includes a synchronization rod 1040, a first gear 1021, a second gear 1022, a first rack 1011, a second rack 1012, a fixing member 1030 and an elastic member 1050. The two ends of the synchronization rod 1040 are respectively connected to the first gear 1021 and the second gear 1022. The first gear 1021 is meshed with the first rack 1011 and can move along the first rack 1011. The second gear 1022 is meshed with the second rack 1012 and can move along the second rack 1012. The tooth grooves of the first rack 1011 and the tooth grooves of the second rack 1012 coincide with each other in the projections in the vertical plane extending forward and backward. The drawer mounting structure 1000 is used for refrigeration equipment.

[0051] In this embodiment, a fixing member 1030 is provided on the first gear 1021, and an accommodating cavity 1031 is opened at one end of the fixing member 1030 away from the first gear 1021, one end of the synchronization rod 1040 extends into the accommodating cavity 1031, and the other end of the synchronization rod 1040 is connected to the second gear 1022, and an elastic member 1050 is provided in the fixing member 1030, and two ends of the elastic member 1050 are respectively abutted against the fixing member 1030 and the synchronization rod 1040, and the elastic force direction of the elastic member 1050 coincides with the axial direction of the synchronization rod 1040, and the axial direction of the accommodating cavity 1031 coincides with the axial direction of the synchronization rod 1040.

[0052] By setting the fixing member 1030, the distance between the first gear 1021 and the second gear 1022 can be conveniently adjusted, and multiple adjustments can be made according to the matching conditions of the tooth grooves during the installation of the synchronization rod 1040, thereby reducing the difficulty of installing the drawer door 4000.

[0053] The use steps of the drawer installation structure 1000 of this embodiment are as follows. After the first gear 1021, the fixing member 1030, the elastic member 1050, the synchronization rod 1040 and the second gear 1022 are connected in sequence, the first gear 1021 is meshed with the first rack 1011 and placed, and then the second gear 1022 is meshed with the second rack 1012 and placed. After placement, check whether the tooth grooves of the rack meshed with the first gear 1021 and the second gear 1022 are aligned. If not, push the second gear 1022 along the axial direction of the synchronization rod 1040 to drive the synchronization rod 1040 to compress the elastic member 1050, thereby separating the second gear 1022 from the second rack 1012, reposition the second gear 1022, and observe whether the tooth grooves of the rack meshed with the first gear 1021 and the second gear 1022 are aligned. Adjust the second gear 1022 multiple times until the tooth grooves meshed with the first gear 1021 and the second gear 1022 are aligned.

[0054] The axial direction of the accommodating chamber 1031 coincides with the axial direction of the synchronization rod 1040, so that the accommodating chamber 1031 will not interfere with the movement of the synchronization rod 1040, thereby reducing wear. The elastic force direction of the elastic member 1050 coincides with the axial direction of the synchronization rod 1040, so that the synchronization rod 1040 is only adjusted along the axial direction of the synchronization rod 1040. The elastic member 1050 does not act on the circumferential rotation of the synchronization rod 1040, thereby making the synchronous rotation between the synchronization rod 1040, the first gear 1021, the second gear 1022 and the fixing member 1030 more stable.

[0055] In other embodiments, the fixing member 1030 may be disposed on the second gear 1022, and a receiving cavity 1031 is provided at one end of the fixing member 1030 away from the second gear 1022, one end of the synchronization rod 1040 extends into the receiving cavity 1031, and the other end of the synchronization rod 1040 is connected to the first gear 1021. The fixing member 1030 may also be disposed on both the first gear 1021 and the second gear 1022, and the receiving cavities 1031 of the two fixing members 1030 are disposed opposite to each other, and the two ends of the synchronization rod 1040 extend into the two receiving cavities 1031 respectively and abut against the elastic member 1050 in the receiving cavity 1031. By disposing the fixing member 1030 on both the first gear 1021 and the second gear 1022, when adjusting the distance between the first gear 1021 and the second gear 1022, the elastic members 1050 in the two fixing members 1030 are squeezed, the adjustment range is larger, and the drawer installation structure 1000 is more convenient to adjust.

[0056] In other embodiments, the synchronization rod 1040 may also include a plurality of connecting rods, which are sequentially sleeved along the axis direction of the synchronization rod 1040, wherein the connecting rod close to the fixing member 1030 extends into the accommodating cavity 1031 and is connected to the elastic member 1050. Through the multiple nested connecting rods, the distance between the first gear 1021 and the second gear 1022 can be adjusted more easily and flexibly.

[0057] In order to make the first gear 1021, the second gear 1022, the fixing member 1030 and the synchronization rod 1040 rotate synchronously, and avoid the problem that the second gear 1022 does not move along the second rack 1012 when the first gear 1021 moves along the first rack 1011, thereby causing the problem of misaligned teeth, the outer wall surface of the portion of the synchronization rod 1040 extending into the accommodating cavity 1031 is adapted to the shape of the inner wall surface of the fixing member 1030. Preferably, the cross section of the portion of the synchronization rod 1040 extending into the accommodating cavity 1031 is a polygon, and at least one corner of the polygon is clamped on the inner wall surface of the fixing member 1030. In order to further improve the stability of the clamping, preferably, each corner of the polygon is clamped on the inner wall surface of the fixing member 1030.

[0058] In this embodiment, the cross section of the synchronization rod 1040 is rectangular, the accommodating cavity 1031 is a rectangle that fits the synchronization rod 1040 , and the synchronization rod 1040 extends into the accommodating cavity 1031 and causes the synchronization rod 1040 and the first gear 1021 and the second gear 1022 to rotate synchronously.

[0059] In other embodiments, the cross section of the synchronization rod 1040 extending into the accommodating cavity 1031 may also be a shape without edges and corners, and the synchronization rod 1040 and the fixing member 1030 rotate synchronously through the friction force generated between the outer peripheral surface of the synchronization rod 1040 and the inner wall surface of the fixing member 1030. The box body 3000 is provided with an opening, and the first slide rail assembly 2001 and the second slide rail assembly 2002 are respectively horizontally arranged on the left and right sides of the inner wall surface of the box body 3000, and extend in the front-back direction. The first slide rail assembly 2001 includes a first fixed rail 2011 and a first sliding member slidably connected to the first fixed rail 2011, the first rack 1011 is connected to the first fixed rail 2011 and extends in the same direction as the first fixed rail 2011, the second slide rail assembly 2002 includes a second fixed rail 2012 and a second sliding member 2022 slidably connected to the second fixed rail 2012, the second rack 1012 is connected to the second fixed rail 2012 and extends in the same direction as the second fixed rail 2012, the first gear 1021 is engaged with the first rack 1011, the second gear 1022 is engaged with the second rack 1012, the drawer door 4000 is connected to the first sliding member and the second sliding member 2022, and moves along the extension direction of the first slide rail assembly 2001 and the second slide rail assembly 2002 so that the drawer door 4000 covers the opening.

[0060] In other embodiments, the locations of the first slide rail assembly 2001 and the second slide rail assembly 2002 may be selected according to actual conditions and are not specifically limited herein.

[0061] By setting the first slide rail assembly 2001 and the second slide rail assembly 2002 and fixing the first rack 1011 and the second rack 1012, the installation and use of the drawer is facilitated, and the stability and reliability of pulling and pulling the drawer door 4000 are improved. The first slide rail assembly 2001 and the second slide rail assembly 2002 are set on opposite sides of the box body 3000, so that the drawer is evenly stressed and the overall stability is improved.
