[0005] For the above problems, the existing patent provides a solution, but the glass storage rack inside part of existing refrigerator needs to be pulled out from the refrigerator, then moved to the appropriate position for insertion during up and down adjustment, which is inconvenient to adjust, and the glass is fragile, once dropped on the ground during pulling out process, it is easy to break, when storing small volume fresh-keeping box, since the distance of glass storage rack is usually fixed, and most of them are designed according to the common specification of bottle, food packaging box and other articles, the distance between adjacent two glass storage racks is usually large, for small volume fresh-keeping box, the space cannot be fully utilized, resulting in the situation of space waste in the refrigerator.

[0006] Therefore, a refrigerator storage rack capable of lifting and adjusting is proposed. UTILITY MODEL CONTENTS

[0007] The purpose of this invention is to provide a height-adjustable refrigerator shelf, which solves the problem that some existing refrigerators require the entire glass shelf to be pulled out of the refrigerator and moved to the appropriate position for adjustment, which is inconvenient. Furthermore, glass is fragile and easily breaks if dropped during the removal process. When storing small food containers, the spacing between glass shelves is usually fixed and designed for common-sized bottles, jars, and food packaging boxes, resulting in a large distance between adjacent shelves. This makes it difficult to fully utilize the space for smaller food containers, leading to wasted space inside the refrigerator.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a height-adjustable refrigerator shelf, comprising two fixed plates, a shelf mechanism provided between the opposite sides of the two fixed plates, the number of shelf mechanisms being four, a limit mechanism provided at the bottom of the fixed plates, and a shelf provided on the opposite sides of both fixed plates.

[0009] The shelf mechanism includes several first shelf rods, several insertion holes, several springs, and several second shelf rods. The left side of the first shelf rod is fixedly connected to the left shelf plate, and the right side of the second shelf rod is fixedly connected to the right shelf plate. The insertion holes are opened inside the first shelf rods, and the springs are movably disposed inside the insertion holes. The second shelf rods are movably inserted into the insertion holes, and the surface of the second shelf rods is in contact with the surface of the springs.

[0010] Preferably, the surfaces of the first and second shelves are both fixedly connected with pinch blocks, and the number of pinch blocks is four. Adjacent pinch blocks are movably connected with connecting strips, and the number of connecting strips is two.

[0011] Preferably, three limiting posts are fixedly connected to opposite sides of the two shelves. A limiting hole is provided between opposite sides of the two fixed plates to cooperate with the limiting posts, and the limiting posts are movably inserted into the limiting holes.

[0012] Preferably, a thin plate is fixedly connected between the rear sides of the two fixed plates, and the thin plate has a number of through slots that are evenly distributed inside the thin plate.

[0013] Preferably, the limiting mechanism includes two rotating columns, two anti-slip blocks, a support plate, and two threaded holes. The threaded holes are opened inside the support plate, the surface of the rotating columns is threadedly connected to the inner wall of the threaded holes, and the anti-slip blocks are fixedly connected to the rotating columns on the side closest to the rotating columns.

[0014] Preferably, the bottom of the support plate is fixedly connected with an anti-slip pad, and the number of anti-slip pads is two and they are symmetrically distributed on the bottom of the support plate.

[0015] Preferably, the fixing plate, the first shelf rod, the second shelf rod, the pinch block, the shelf plate, and the thin plate are all made of food-grade metal.

[0016] Preferably, both the anti-slip block and the anti-slip pad are made of TPE soft rubber granules.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application allows the first and second shelf rods to move in the pinching direction by applying pinching force with a hand gripper. This causes the shelf to move, thereby disengaging the limiting post from the limiting hole. The height of the first and second shelf rods can be adjusted to accommodate food storage containers of different heights but smaller sizes. Placing the food storage containers on top of the first and second shelf rods avoids the direct stacking of food storage containers, which could cause them to be squeezed or have their ventilation holes blocked, thus preventing damage to the food or fruit inside. This eliminates the need to remove and adjust the refrigerator's built-in glass partition, making full use of the refrigerator's internal space. Furthermore, the food or fruit inside the food storage containers will not be squeezed or damaged due to direct stacking.

[0019] 2. This application moves the two fixing plates to the top of the glass partition inside the refrigerator. At this time, the anti-slip pad can stably support the support plate and the fixing plate. Then, the rotating column is rotated so that the surface of the anti-slip block is in close contact with the inner wall of the refrigerator. At this time, the fixing plate, the first shelf and the second shelf can be limited inside the refrigerator. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 The present invention provides the following technical solution:

[0029] A height-adjustable refrigerator shelf includes two fixed plates 1, a shelf mechanism 4 is provided between the opposite sides of the two fixed plates 1, the number of shelf mechanisms 4 is four, a limit mechanism 6 is provided at the bottom of the fixed plates 1, and a shelf 5 is provided on the opposite sides of the two fixed plates 1.

[0030] The shelf mechanism 4 includes several first shelf rods 401, several insertion holes 402, several springs 403, and several second shelf rods 404. The left side of the first shelf rod 401 is fixedly connected to the left shelf plate 5, and the right side of the second shelf rod 404 is fixedly connected to the right shelf plate 5. The insertion hole 402 is opened inside the first shelf rod 401, the spring 403 is movably disposed inside the insertion hole 402, and the second shelf rod 404 is movably inserted into the insertion hole 402. The surface of the second shelf rod 404 is in contact with the surface of the spring 403.

[0031] In this embodiment: by moving the fixing plate 1 and the support plate 603 to the top of the glass partition inside the refrigerator, and then rotating the rotating column 601 so that the surface of the anti-slip block 602 is in close contact with the inner wall of the refrigerator, the support plate 603, the fixing plate 1, the first shelf 401 and the second shelf 404 are confined inside the refrigerator. This allows for convenient layering of small food storage containers on top of the first shelf 401 and the second shelf 404. By pinching the two adjacent pinch blocks 8, the spring 403 is compressed, which moves the shelf 5, causing the limiting post 11 to disengage from the limiting hole 10. The shelf 5 is then moved to the position of the limiting hole 10 where the height needs to be adjusted. Then, the pinch blocks 8 are released, the spring 403 rebounds, and the limiting post 11 is inserted into the limiting hole 10. This completes the height adjustment of the first shelf 401, the second shelf 404 and the shelf 5, facilitating the placement of food storage containers. By using food storage containers of different heights, you can avoid the problem of containers being crushed or having their ventilation holes blocked when stacked directly, which could damage the food or fruit inside. This also eliminates the need to remove and adjust the built-in glass shelves, allowing for convenient and efficient use of the refrigerator's interior space. This avoids the inconvenience of adjusting glass shelves in some refrigerators, which require pulling the entire shelf out of the refrigerator and then moving it to the desired position. Furthermore, glass is fragile and easily breaks if dropped during this process. When storing smaller food storage containers, the fixed spacing of the glass shelves, often designed for common-sized bottles, jars, and food packaging, can lead to a large gap between adjacent shelves. This results in wasted space inside the refrigerator, as smaller containers cannot be fully utilized.

[0032] Specifically, such as Figure 4 As shown, the surfaces of the first shelf 401 and the second shelf 404 are both fixedly connected with pinch blocks 8, and there are four pinch blocks 8 in total. The interiors of adjacent pinch blocks 8 are movably provided with connecting strips 9, and there are two connecting strips 9 in total.

[0033] Specifically, such as Figure 6 As shown, two shelves 5 are fixedly connected to three limit posts 11 on opposite sides. Limiting holes 10 are provided between the opposite sides of the two fixed plates 1 to cooperate with the limit posts 11. The limit posts 11 are movably inserted into the limit holes 10.

[0034] Specifically, such as Figure 2 As shown, a thin plate 2 is fixedly connected between the rear sides of the two fixed plates 1. A through groove 3 is opened inside the thin plate 2. The number of through grooves 3 is several and they are evenly distributed inside the thin plate 2.

[0035] In this embodiment: the two adjacent pinch blocks 8 are movably connected by the connecting strip 9, which allows the pinch blocks 8 to move while preventing the two pinch blocks 8 from being too far apart, causing the second shelf rod 404 to come out of the insertion hole 402. The shelf plate 5, the first shelf rod 401 and the second shelf rod 404 are limited by the limiting post 11 moving into the limiting hole 10. The two fixing plates 1 are connected by the thin plate 2 with the through groove 3, so that the two fixing plates 1 are stably connected and the circulation of cold air inside the refrigerator is not affected.

[0036] Specifically, such as Figure 5 As shown, the limiting mechanism 6 includes two rotating pillars 601, two anti-sliding blocks 602, a support plate 603, and two threaded holes 604. The threaded holes 604 are opened inside the support plate 603. The surface of the rotating pillars 601 is threadedly connected to the inner wall of the threaded holes 604. The anti-sliding blocks 602 are fixedly connected to the rotating pillars 601 on the side closest to the rotating pillars 601.

[0037] Specifically, such as Figure 5 As shown, the bottom of the support plate 603 is fixedly connected with two anti-slip pads 7, which are symmetrically distributed on the bottom of the support plate 603.

[0038] In this embodiment: by moving the fixing plate 1 and the support plate 603 to the top of the glass partition inside the refrigerator, the anti-slip pad 7 can stably support the support plate 603 and the fixing plate 1. Then, the rotating column 601 is rotated. The rotating column 601 is connected to the threaded hole 604. When the rotating column 601 is rotated, it can move and move the rotating column 601 until the surface of the anti-slip block 602 is in close contact with the inner wall of the refrigerator. At this time, the fixing plate 1, the first shelf 401 and the second shelf 404 can be limited inside the refrigerator.

[0039] Specifically, such as Figure 1 and Figure 4 As shown, the fixing plate 1, the first shelf rod 401, the second shelf rod 404, the pinch block 8, the shelf 5, and the thin plate 2 are all made of food-grade metal.

[0040] Specifically, such as Figure 5 As shown, both the anti-slip slider 602 and the anti-slip pad 7 are made of TPE soft rubber granules.

[0041] In this embodiment: Since the fixing plate 1, the first shelf rod 401, the second shelf rod 404, the pinch block 8, the shelf 5 and the thin plate 2 are all made of food-grade metal, it can be ensured that no harmful substances will be released during long-term contact with food, thus ensuring food safety. Since the anti-slip block 602 and the anti-slip pad 7 are both made of TPE soft rubber granules, it can be ensured that the anti-slip block 602 and the anti-slip pad 7 will not harden at low temperatures and will still have an anti-slip effect.

[0042] Working principle: By moving the fixing plate 1 and the support plate 603 to the top of the glass partition inside the refrigerator, the anti-slip pad 7 provides stable support for the support plate 603 and the fixing plate 1. Then, rotate the rotating column 601, which is connected to the threaded hole 604. When the rotating column 601 rotates, it moves until the surface of the anti-slip block 602 is in close contact with the inner wall of the refrigerator. At this point, the fixing plate 1, the first shelf 401, and the second shelf 404 are confined inside the refrigerator. Since the anti-slip block 602 and the anti-slip pad 7 are both made of TPE soft rubber granules, they will not harden at low temperatures and will still have an anti-slip effect. Then, items that need to be placed can be placed inside. The food storage containers to be placed are layered on top of the first shelf 401 and the second shelf 404. When different heights of food storage containers need to be placed, the adjacent clamping blocks 8 are pinched. Since the clamping blocks 8 are fixed to the first shelf 401 and the second shelf 404 respectively, the force applied by the fingers overcomes the elasticity of the spring 403, compressing the spring 403 and causing the second shelf 404 to move into the insertion hole 402. This allows the limiting post 11 to disengage from the limiting hole 10, thus moving the first shelf 401, the second shelf 404, and the shelf 5 to the desired position. Then, the clamping blocks 8 are released, the spring 403 rebounds, and the limiting post 11 inserts into the corresponding limiting hole 10, completing the movement of the first shelf 401 and the second shelf 404. The height adjustment allows for convenient placement of food storage containers of different heights. By placing smaller containers on top of the first shelf 401 and the second shelf 404, it avoids the risk of containers being crushed or having their ventilation holes blocked, which could damage the food or fruit inside. This eliminates the need to remove and adjust the refrigerator's built-in glass shelves, maximizing the use of internal space. A thin plate 2 with a slot 3 connects the two fixed plates 1, ensuring a stable connection without obstructing the flow of cold air inside the refrigerator. This avoids the need to completely remove the glass shelves from the refrigerator and reposition them for height adjustment, as is common in some existing refrigerators. To avoid inconvenience, and because glass is relatively fragile, it is very easy to break if dropped during the removal process. When storing small food containers, the spacing between glass shelves is usually fixed, and most are designed to hold common-sized bottles, jars, food packaging boxes, etc. The distance between two adjacent glass shelves is often large. For small food containers, this space cannot be fully utilized, resulting in wasted space inside the refrigerator. Since the fixed plate 1, the first shelf rod 401, the second shelf rod 404, the pinch block 8, the shelf board 5, and the thin plate 2 are all made of food-grade metal, it can be ensured that no harmful substances will be released during long-term contact with food, thus ensuring food safety. It should be noted that...The depth of the socket 402 is sufficient to accommodate the spring 403 and part of the second shelf 404, facilitating the movement of the second shelf 404 within the socket 402.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
