DETAILED DESCRIPTION

[0026] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given. However, the protection scope of the present invention is not limited to the following embodiments. In the description of the present invention, words indicating directions or positional relationships such as "front", "rear", "left", and "right" are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0027] The embodiment discloses a drawer installation structure of a refrigerator, such as Figure 1-Figure 6 As shown, the drawer body 2 includes a slide rail 5 and a slider 4, and the drawer body 2 is installed in the storage area of ​​the refrigerator body 1 through the slide rail 5 and the slider 4. Specifically, the slide rail 5 is arranged on the inner walls of both sides of the refrigerator storage area 3, and the slider 4 is arranged on both sides of the drawer body 2. The slider 4 is movably plugged into the inside of the slide rail 5, so that the drawer can be installed in the refrigerator storage area 3 by plugging;

[0028] In this embodiment, the slide rails 5 are configured as grooves on both sides of the inner wall of the refrigerator storage area 3. More specifically, as shown in FIG. Figure 1-Figure 3 As shown, the slide rail 5 includes a slide bar 501 and a slide track 502, each slide rail 5 includes two slide bars 501, and the two slide bars 501 are distributed up and down, the upper and lower slide bars 501 are respectively fixed on the inner wall of the refrigerator storage area 3, and a spacing is set between the upper and lower slide bars 501. The space between the upper and lower slide bars 501 is the slide track 502, and the slider 4 is movably inserted in the slide track 502, so that the drawer body 2 can be movably pulled and drawn.

[0029] In order to limit the position of the drawer body 2, Figure 2 and Figure 3As shown, a limit block 6 is fixedly arranged at the bottom of the upper slide bar 501, and the limit block 6 is located at the front end of the upper slide bar 501, specifically arranged at the entrance of the slideway 502, the height of the limit block 6 is less than the distance between the two slide bars 501, the bottom surface of the limit block 6 and the upper end surface of the lower slide bar 501 have a distance, the height of the slider 4 matches the distance between the limit block 6 and the lower slide bar 501, and the slider 4 is inserted into the slideway 502 from between the limit block 6 and the lower slide bar 501;

[0030] like Figure 3-Figure 5 As shown, a card block 20 is arranged above the slider 4, and the card block 20 is specifically arranged above the end of the slider 4. The card block 20 and the slider 4 are arranged to be movably plugged, and the card block 20 is also supported by the elastic member 10, so that the card block 20 can be elastically extended and retracted on the slider 4. In addition, the rear end surface of the card block 20 above the slider 4 is an inclined surface. In other words, the section of the card block 20 above the slider 4 is a right triangle in the side view, so that when the drawer body 2 is inserted into the refrigerator storage area 3, the slider 4 is inserted between the limit block 6 and the lower slide bar 501, and at the same time, the upper card block 20 will contact the bottom wall of the limit block 6 through the inclined surface. The card block 20 is compressed so that it shrinks into the inside of the slider 4, thereby ensuring that the slider 4 can be inserted smoothly. Then, the card block 20 moves to the rear end of the limit block 6 as the slider 4 is inserted. After the card block 20 is separated from the limit block 6, the card block 20 will lose the limit of the limit block 6, thereby making the card block 20 rise through the rebound of the elastic member 10, thereby limiting the drawer body 2 through the card block 20 and the limit block 6, so that when the drawer body 2 is pulled out, it can be limited by the contact between the card block 20 and the limit block 6, and then when the drawer body 2 is installed, there is no need to tilt the drawer body 2, and the drawer body 2 can be directly inserted horizontally.

[0031] Specifically, Figure 4As shown, an inner groove 7 is provided inside the end of the slide 4, and a plug-in groove 8 is provided above the inner groove 7, and the plug-in groove 8 runs through the top surface of the slide 4, and a bottom block 9 is provided inside the inner groove 7 for longitudinal sliding, and a card block 20 is movably plugged into the plug-in groove 8, and the bottom wall of the card block 20 is fixedly connected to the bottom block 9, and the top of the card block 20 extends to the top of the slide 4. An elastic member 10 is also provided at the bottom of the bottom block 9 to elastically support it. In addition, in order to be able to horizontally pull out the drawer body 2 when it is needed, a pull-out member 10 is fixedly connected to the bottom of the bottom block 9. Rope 11, and one end of the pull rope 11 passes through the inner groove 7 and extends to the outside of the slider 4, and the end of the pull rope 11 located outside the slider 4 passes through the front panel of the drawer body 2 and extends to the front of the panel, and the end of the pull rope 11 located in front of the panel of the drawer body 2 is fixedly provided with a pull ring 12, and then when the drawer body 2 needs to be pulled out, the bottom block 9 can be pulled downward by the pull ring 12, so that the bottom block 9 moves downward and drives the card block 20 to move downward, and the card block 20 moves downward and shrinks to the inside of the slider 4, thereby releasing the limit of the card block 20 and the limit block 6, so that the drawer body 2 can be pulled out horizontally.

[0032] Through the above arrangement, even if there are many articles and foods in the drawer body 2, the drawer body 2 can be directly pulled out and inserted horizontally without tilting the drawer body 2, thereby avoiding the situation where a large number of articles are placed inside the drawer body 2 and the tilting operation of the drawer body 2 is affected, causing the user to need to take out the articles.

[0033] In actual use scenarios, users may not realize that the actual load is light and apply more force than necessary, thus causing mechanical structure collision. In life, this is a typical case of perceptual bias-behavior overload-mechanical collision, and there are many cases where the limit structure is damaged due to this reason.

[0034] In this embodiment, for example, the drawer body 2 may store items of different weights, such as sometimes being filled with food and sometimes only a few cups. If the user habitually pulls the drawer hard, especially when they think the items inside are heavy but are actually light, the drawer may be pulled out quickly, causing the limiting structure to be impacted. Therefore, in order to avoid the above situation, a speed reduction mechanism 13 is provided so that when the user quickly pulls out the drawer body 2, the friction force can be increased to reduce the withdrawal speed, thereby avoiding the limit structure being damaged by impact.

[0035] Specifically, Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the deceleration mechanism 13 includes a conversion component 131, a rotating wheel 132 and a brake component 133, wherein the conversion component 131 is used to convert the translation of the drawer body 2 into the rotation of the rotating wheel 132, so that the faster the drawer body 2 is pulled out, the faster the rotation speed of the rotating wheel 132 is, and a brake component 133 is also provided inside the rotating wheel 132, and the brake component 133 is configured to extend through the centrifugal force generated when the rotating wheel 132 rotates to slow down the drawer body 2.

[0036] like Figure 2 , Figure 3 and Figure 5 As shown, the conversion component 131 includes a gear 311 and a rack 312, wherein the rack 312 is fixedly arranged on one side of the lower slide bar 501, and the upper end surface of the rack 312 is lower than the upper end surface of the lower slide bar 501, and the upper end surface of the rack 312 is provided with a plurality of teeth equidistantly arranged along the length direction of the rack 312, and a wheel groove 14 is provided inside the end of the slide bar 4, and a gear 311 is rotatably arranged inside the wheel groove 14, and the gear shaft of the gear 311 is rotatably connected to the slide bar 4, and the bottom of the wheel groove 14 passes through the lower end surface of the slide bar 4, and the bottom outer wall of the gear 311 inside the wheel groove 14 extends to the outside of the slide bar 4 through the bottom opening of the wheel groove 14, and the gear 311 and the rack 312 are meshed with each other, so that when the drawer body 2 is translated, the linear motion of the drawer body 2 can be converted into the circular motion of the gear 311 through the cooperation of the gear 311 and the rack 312.

[0037] Furthermore, through the above arrangement, the translational linear motion of the drawer body 2 when being drawn out is converted into the rotation of the gear 311, and the faster the drawer body 2 is, the faster the gear 311 will rotate.

[0038] A clearance groove 15 is provided on the outer side of the slider 4, that is, the back side of the slider 4 fixed to the drawer body 2, and the other end of the gear shaft extends into the clearance groove 15. A rotating wheel 132 is provided inside the clearance groove 15. The rotating wheel 132 is fixedly sleeved on the outer side of the gear shaft and is concentric with each other, so that when the gear 311 rotates, the rotating wheel 132 can be driven to rotate synchronously;

[0039] It should be noted that the wheel surface of the rotating wheel 132 is spaced apart from the top surface of the lower slide bar 501 and the bottom surface of the upper slide bar 501, respectively, so that the wheel surface of the rotating wheel 132 will not contact the outer walls of the upper and lower slide bars 501. In addition, the thickness of the rotating wheel 132 is less than the depth of the give way groove 15, and the outer side surface of the rotating wheel 132 is spaced apart from the inside of the refrigerator storage area 3, so as to prevent the rotating wheel 132 from contacting the inner wall of the refrigerator storage area 3. In addition, it should be noted that the rotating wheel 132 is located above the lower slide bar 501.

[0040] like Figure 5 and Figure 6As shown, the brake assembly 133 is arranged inside the rotating wheel 132, and at least two brake assemblies 133 are arranged. In this embodiment, four brake assemblies 133 are arranged in a circular array with the center of the rotating wheel 132 as the center.

[0041] Specifically, the brake assembly 133 includes a slide groove 331 and a movable block 332. The slide groove 331 is opened in the radial direction of the rotating wheel 132, and the slide groove 331 penetrates the outer circumferential wall of the rotating wheel 132. The movable block 332 is slidably arranged inside the slide groove 331. The movable block 332 is provided with an anti-skid layer on one side close to the outer ring of the rotating wheel 132. The anti-skid layer can be set as a rubber layer, so that the friction can be increased when the movable block 332 contacts the outer wall of the slide bar 501.

[0042] Through the above-mentioned arrangement, when the drawer body 2 is quickly pulled out, the gear 311 rotates at a high speed through the cooperation of the gear 311 and the rack 312, and the gear 311 drives the rotating wheel 132 to rotate synchronously. After the movable block 332 moves along the guide of the slide groove 331 due to the centrifugal force, the outer wall of the movable block 332 contacts the outer wall of the slide bar 501, thereby increasing its friction force and reducing the pulling-out speed of the drawer body 2.

[0043] A fixed plate 16 is also fixedly provided inside the slide groove 331, and the fixed plate 16 is located between the movable block 332 and the center of the rotating wheel 132. A sliding rod 17 is also fixedly provided on the end of the movable block 332 facing the center of the rotating wheel 132, and the sliding rod 17 moves through the fixed plate 16 and extends to the side of the fixed plate 16 facing the center of the rotating wheel 132. A limiting plate 18 is fixedly provided on the end of the sliding rod 17 located on the side of the fixed plate 16 facing the center of the rotating wheel 132, and a spring 19 is provided between the limiting plate 18 and the fixed plate 16. The spring 19 allows the movable block 332 to be retracted into the slide groove 331 under normal conditions. Only when the rotating wheel 132 rotates at a high speed, the spring 19 is compressed by the centrifugal force, and the movable block 332 extends out to contact the outer wall of the slide bar 501 to increase the friction, thereby reducing the extraction speed of the drawer body 2.

[0044] The principle of the present invention is as follows: the present invention provides the limit block 6 and the card block 20. When the drawer body 2 is inserted into the refrigerator storage area 3, the slide block 4 is inserted between the limit block 6 and the lower slide bar 501. At the same time, the upper card block 20 is compressed by the contact between the inclined surface and the bottom wall of the limit block 6, so that the card block 20 shrinks to the inside of the slide block 4, thereby ensuring that the slide block 4 can be smoothly inserted. After that, the card block 20 is separated from the limit block 6 as the slide block 4 is inserted, and the card block 20 loses the limit of the limit block 6, so that the card block 20 rises through the rebound of the elastic member 10, thereby The positioning block 6 limits the drawer body 2, so that when installing the drawer body 2, there is no need to tilt the drawer body 2, and the drawer body 2 can be directly inserted horizontally. In addition, by setting the speed reduction mechanism 13, when the drawer body 2 is quickly pulled out, the gear 311 and the rack 312 cooperate to make the gear 311 rotate at a high speed, and the gear 311 will drive the rotating wheel 132 to rotate synchronously. After the movable block 332 moves along the guide of the slide groove 331 due to centrifugal force, the outer wall of the movable block 332 contacts the outer wall of the slide bar 501, thereby increasing its friction and reducing the withdrawal speed of the drawer body 2.

[0045] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
