[0044] Wherever possible, the various aspects and features described and illustrated in this specification may be applied individually, and these individual aspects may serve as the subject matter of a divisional application.

[0045] This utility model provides a push-type refrigerator shelf, such as Figures 1 to 3 As shown, the push-type refrigerator shelf includes a shelf body 1, a push plate 2, a roller mechanism 3, and a locking mechanism 4.

[0046] The shelf body 1 has a base plate 11 for placing items and a track 12 extending in the front-to-back direction. A push plate 2 is located above the base plate 11 and has a mating part 21 that guides and engages with the track 12. One end of a reel mechanism 3 is connected to the front end of the shelf body 1, and the other end is connected to the push plate 2. The reel mechanism 3 is configured to drive the push plate 2 to move from back to front along the track 12 when it is elastically wound up.

[0047] When the push plate 2 moves, it can push items located at the back of the base plate 11 forward, making it more convenient for users to take items from the front of the shelf body 1. Furthermore, once the items are pushed to the front of the shelf body 1, they are more likely to be seen by users and less likely to be forgotten, thus reducing the chances of food expiring due to prolonged storage.

[0048] The reel mechanism 3 uses its own elastic force as the power to drive the push plate 2. It has a simple structure, low cost, and does not require an electric drive device.

[0049] The locking mechanism 4 is located between the rear end of the shelf body 1 and the push plate 2, and is used to lock or unlock the push plate 2 at the rear end of the shelf body 1.

[0050] When push plate 2 is needed, locking mechanism 4 unlocks push plate 2. When push plate 2 is not needed, locking mechanism 4 can lock push plate 2 in position, preventing it from moving forward by the reel mechanism 3. Users can use push plate 2 flexibly as needed.

[0051] like Figure 3As shown, the winding mechanism 3 includes a fixed shaft 31 and a coil spring 32. The end of the coil spring 32 located in the middle after winding is defined as the inner end, and the end located on the outside is defined as the outer end. The inner end of the coil spring 32 is connected to the fixed shaft 31 and is wound around the fixed shaft 31 by its own elasticity. The coil spring 32 unfolds or winds up along the front-back direction of the base plate 11. The two ends of the winding mechanism 3 are the outer ends of the fixed shaft 31 and the coil spring 32, respectively. One of the outer ends of the fixed shaft 31 and the coil spring 32 is connected to the front end of the shelf body 1, and the other is connected to the push plate 2.

[0052] The outer ends of the fixed shaft 31 and the coil spring 32 can be detachably fixed to the shelf body 1 or the push plate 2, for example, by fasteners, making assembly and disassembly convenient. After prolonged use, the elasticity of the coil spring 32 decreases, allowing it to be easily removed and replaced.

[0053] The shelf body 1 also includes a front baffle 13, which is fixed to the front end of the base plate 11 and blocks items on the base plate. Items are placed between the front baffle and the push plate 2. The push plate 2 moves forward to push the items on the base plate 11, and the front baffle 13 prevents items from falling off the front end of the base plate 11. The front baffle 13 can be made of transparent plastic or glass to allow the user to see the items on the base plate 11. The base plate 11 and the front baffle 13 can be a single piece or connected in a detachable manner.

[0054] The shelf body 1 also includes two side panels 14, which are fixed to opposite sides of the base plate 11, blocking items on the left and right sides of the base plate 11. The base plate 11 and the side panels 14 can be an integral structure or connected in a detachable manner. Removing the two side panels 14 facilitates cleaning of the base plate 11 and also increases the capacity of the base plate 11 to hold more items.

[0055] Specifically, the track 12 can be set on the base plate 11 or on the side plate 14. The track 12 can be set as a groove, a protrusion or other conventional guide structure. The mating part 21 of the push plate 2 is set to be adapted to the track 12. The mating part 21 can also be equipped with a pulley that can roll along the track 12.

[0056] One end of the roller mechanism 3 can be connected to the front end of the bottom plate 11, the front end of the side plate 14, or the front baffle 13 of the shelf body 1. The other end of the roller mechanism 3 can be connected to the side, bottom, or other position of the push plate 2, and should avoid interference with items on the bottom plate 11. The push plate 2 is erected above the bottom plate 11, and the opposite sides of the push plate 2 extend to the left and right side plates 14 of the bottom plate 11, respectively.

[0057] In one embodiment, the fixed shaft 31 is connected to the push plate 2, and the outer end of the coil spring 32 is connected to the front end of the shelf body 1. For example... Figure 3 and Figure 4 As shown, the outer end of the coil spring 32 is connected to the front end of the base plate 11, and the other end is connected to the bottom of the push plate 2.

[0058] In another embodiment, the fixed shaft 31 is connected to the front end of the shelf body 1, and the outer end of the coil spring 32 is connected to the push plate 2.

[0059] In some implementations, such as Figure 5 and Figure 6 As shown, rails 12 are respectively provided on opposite sides of the base plate 11, and mating parts 21 that cooperate with the corresponding rails 12 are respectively provided on the bottom of opposite sides of the push plate 2. The rails 12 on both sides can guide the left and right sides of the push plate 2, which is conducive to the stable movement of the push plate 2. The rails 12 can be set on the opposite edges of the base plate 11, so that items on the base plate 11 are less likely to enter the rails 12.

[0060] In some embodiments, a winding mechanism 3 is provided on each of the opposite sides of the push plate 2, and at least two winding mechanisms 3 are provided. The winding mechanisms 3 are located near the mating part 21 on the corresponding side. The winding mechanisms 3 on both sides can simultaneously drive the left and right sides of the push plate 2, so that the push plate 2 can move forward smoothly.

[0061] In some implementations, such as Figure 4 As shown, a scroll box 22 can be installed on the shelf body 1 or the push plate 2 to protect the scroll mechanism 3. The scroll box 22 has an inner cavity, the fixed shaft 31 is installed in the inner cavity of the scroll box 22, and the coil spring 32 can be wound into the inner cavity of the scroll box 22.

[0062] like Figure 6 In the specific embodiment shown, a scroll box 22 is provided on each of the opposite sides of the push plate 2, and the scroll mechanism 3 is disposed in the inner cavity of the scroll box 22 on the corresponding side. The scroll box 22 is provided with an opening 221 for the extension of the scroll spring 32. The opening 221 can be provided at the bottom of the scroll box 22, or at the front end of the scroll box 22, or at other positions.

[0063] In one implementation, such as Figure 5 , Figure 6 and Figure 7 As shown, the track 12 includes a groove structure 121, and the mating part 21 of the push plate 2 is fitted in the groove structure 121 and slides along the groove structure 121. The bottom of the reel box 22 is slidably fitted in the groove structure 121, and as the push plate 2 slides in the groove structure 121, it strengthens the support and guidance of the push plate 2.

[0064] After unfolding, the coil spring 32 is located in the groove structure 121, so that the unfolded coil spring 32 is lower than the top surface of the base plate 11, which can reduce the situation where objects on the base plate 11 press down on the coil spring 32 and hinder the coil spring 32 from winding.

[0065] Specifically, the scroll box 22 is larger in the front-to-back direction than the thickness of the push plate 2, thus providing support for the push plate 2. For example... Figure 6 As shown, the roll box 22 can be set behind the push plate 2 to provide support and balance the force on the front side of the push plate 2.

[0066] Furthermore, the side wall of the groove structure 121 is provided with a limiting groove 122 extending in the front-back direction, and the bottom of the mating part 21 of the push plate 2 or the scroll box 22 is provided with a slider 23. The slider 23 is slidably fitted in the limiting groove 122 to limit the push plate 2, so that the push plate 2 can move stably along the track 12.

[0067] In some embodiments, the push-locking mechanism 4 includes a resilient latch 41 and a locking block 42 having a locked state and an unlocked state, one of the resilient latch 41 and the locking block 42 being fixed to the rear end of the shelf body 1, and the other being fixed to the push plate 2.

[0068] The elastic latch 41 has a lock hole 411, and an elastic claw 412 is provided in the lock hole 411. In the locked state, the lock head 420 of the lock block 42 is inserted into the lock hole 411 and engages with the elastic claw 412. The elastic latch 41 and the lock block 42 lock each other, thereby fixing the position of the push plate 2.

[0069] like Figure 1 and Figure 2 In the illustrated embodiment, the elastic latch 41 is fixedly connected to the bottom rear side of the push plate 2, and is positioned near the middle of the rear side of the push plate 2, with the locking hole 411 facing rearward; the locking block 42 is fixedly connected to the rear end of the base plate 11, with its position corresponding to the elastic latch 41, and the locking head 420 of the locking block 42 facing forward. The position of the locking block 42 is fixed, and the elastic latch 41 moves back and forth with the push plate 2. When the push plate 2 moves rearward along the track 12 to the rear end of the base plate 11, the locking block 42 can be inserted into the locking hole of the elastic latch 41 and engage with the elastic claw 412, thereby locking the push plate 2 at the rear end of the base plate 11.

[0070] When push plate 2 is needed, pull push plate 2 forward to disengage lock block 42 from elastic pawl 412, thereby unlocking push plate 2. After unlocking, push plate 2 can move forward along track 12 under the action of coil spring 32.

[0071] In detail, such as Figure 6 and Figure 8 As shown, the push plate 2 has a mounting sleeve 24 on its rear side, forming a mounting hole 241 facing rearward, and the elastic latch 41 is fixed in the mounting hole 241. The mounting sleeve 24 and the push plate 2 can be an integral structure, and the elastic latch 41 can be detachably connected to the mounting sleeve 24 by snap-fit, fastener connection or other means, and can be replaced.

[0072] like Figure 8 and Figure 9 As shown, the elastic latch 41 has two elastic claws 412, which are spaced apart and can move elastically in directions away from or towards each other. Each of the two elastic claws 412 has a protruding limiting part 4121 on its side that is close to each other, used to lock the locking block 42.

[0073] The lock head 420 of the lock block 42 is located at the front end of the lock block 42 and is configured as an enlarged end. The two opposite sides of the front part of the lock head 420 are respectively provided with inclined front guide surfaces 421, which gradually taper from back to front, so that the lock head 420 forms a pointed tip. The opposite ends of the rear part of the lock head 420 are respectively provided with rear guide surfaces 422, which are configured as inclined surfaces or arc surfaces that taper from front to back.

[0074] The locking process of the elastic latch 41 and the locking block 42 is as follows: The push plate 2 moves the elastic latch 41 backward, so that the locking head 420 of the locking block 42 is inserted into the lock hole 411 of the elastic latch 41. Under the guidance of the front guide surfaces 421 on both sides, the locking head 420 enters between the two elastic claws 412. The two elastic claws 412 are pushed apart by the locking head 420 and elastically deform in a direction away from each other. The locking head 420 continues to move into the lock hole 411, passing the limiting part 4121 of the two elastic claws 412. Then, the two elastic claws 412 are reset under the action of elastic restoring force, holding the locking head 420. The limiting part 4121 of the two elastic claws 412 respectively engages with the two rear guide surfaces 422 of the locking head 420.

[0075] When unlocking, push the push plate 2 forward. The push plate 2 moves forward with the elastic latch 41. Under the guidance of the two rear guide surfaces 422, the lock head 420 can push open the two elastic claws 412 again and disengage from the lock hole 411 to achieve unlocking.

[0076] This utility model also provides a refrigerator with an internal storage space, in which a push-pull refrigerator shelf as described above is provided. The push-pull refrigerator shelf can be installed at the top of the storage space, allowing items to be pushed forward for easy viewing and retrieval of items on higher shelves.

[0077] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
