In order to ensure the maximization of space utilization, a storage cabinet or a storage box is generally provided with a storage space along the vertical direction; the storage spaces are stacked in the vertical direction, so that the occupied area in the horizontal direction in the room can be reduced, and the aim of maximizing the utilization of the space is fulfilled. Such as refrigerators, cabinets or cupboards, etc., which are common in daily life.

Specifically, a refrigerator is exemplified as an example. The refrigerator is widely used in domestic life at present because of being capable of preserving and refrigerating foods, foods or vegetables, fruits and the like.

In order to store different foods in a classified manner (for example, vegetables and fruits are usually afraid of freezing and can only be refrigerated and preserved, and meat is easy to deteriorate and needs to be refrigerated and preserved), the internal space of a refrigerator is generally divided into two areas along the height direction, wherein one area is a freezing area, and the freezing area is usually positioned at the lower half part of the refrigerator; the temperature of the freezing area is reduced by a compressor or a refrigerant and the like, and the temperature of the freezing area can be kept in a temperature range below zero under normal conditions, so that food easy to deteriorate can be preserved. The other area is a refrigerating area, which is usually located at the upper part of the refrigerator, and the air of the refrigerating area is usually subjected to heat exchange by using the low temperature of the freezing area, so that the temperature of the refrigerating area is maintained within a temperature range suitable for fresh keeping, for example, 2-5 ℃.

In order to facilitate users to take articles, the taking and placing opening of the refrigerating area usually adopts a vertical hinged door or a double-door design mode. For the freezing area, the temperature of the freezing area needs to be maintained, the freezing area is generally set to be an opening mode of the drawer assembly, and when the drawer assembly is closed, the sealing strip on the drawer assembly is tightly attached to the side wall of the freezing area, so that a good sealing effect is achieved, and the freezing effect of the freezing area is ensured.

However, in the actual use process of the user, after the user pulls out the drawer assembly, the position of the drawer assembly is relatively low, and the user needs to bend down or crouch down to take the article, so that the user experience is poor.

For this reason, in the related art, a vertical sliding rail is provided on the inner wall of the outer door panel of the drawer assembly, and a compression spring is provided at the bottom of the sliding rail; after the drawer assembly is pulled out by a user, the compressed spring has elastic potential energy for resetting, so that the drawer assembly is pushed upwards, and the drawer assembly slides upwards along the sliding rail, so that the height of the drawer assembly can be changed, and the user can conveniently take articles.

However, in the related art, after the drawer assembly stores the articles, the whole weight of the drawer assembly is heavy, and leverage is formed between the drawer assembly and the sliding rail arranged on the inner wall of the drawer assembly door, so that friction force between the drawer assembly and the sliding rail is increased, in addition, the whole surface contact between the drawer assembly and the inner wall of the drawer assembly door is also large; the compression spring is difficult to push the drawer assembly upwards, and even the problem that the compression spring cannot push the drawer assembly upwards can occur.

Fig. 1 is a schematic diagram of an overall structure of a storage device according to an embodiment of the present utility model, and fig. 2 is a side view of the storage device according to the embodiment of the present utility model.

Referring to fig. 1 and 2, an embodiment of the present utility model provides a storage device 10, including: the cabinet 100, the drawer assembly 200, and the first link 300.

Specifically, in the embodiment of the present utility model, the storage device 10 may be, for example, a refrigerator, a cabinet, a wardrobe, or the like. In the embodiment of the utility model, a refrigerator is taken as an example for illustration. The box body 100 may be made of a heat-insulating material, and a compressor or a refrigerator may be disposed in the box body 100 to cool the box body 100.

It will be appreciated that in the embodiment of the present utility model, the housing 100 has a receiving space 101 therein, and the receiving space 101 may be used for storing articles, such as food, vegetables or fruits. Generally, to facilitate the user's taking of the article, an opening of the notification space may be opened at one side of the case 100.

In the embodiment of the utility model, a part of the drawer assembly 200 is movably inserted into the accommodating space 101.

Specifically, the drawer assembly 200 may be inserted into the accommodating space 101 at an opening of the accommodating space 101. It will be appreciated that, given a refrigerator as an example, typically the drawer assembly 200 has a drawer door 202; the drawer door 202 may be made of a heat insulating material, and generally, the drawer door is located outside the accommodating space 101, and a side of the drawer door 202 facing the accommodating space 101 may be provided with a support frame, a basket, and other components, where the basket is mounted on the support frame and is inserted into the accommodating space along with the support frame.

In some specific examples, a sliding rail may also be provided between the drawer assembly 200 and the receiving space 101; for example, in some examples, sliding rails may be provided on the side walls of the drawer assembly 200 and the side walls of the receiving space 101 to facilitate the drawing of the drawer assembly 200. In other examples, sliding tracks may also be provided on the bottom walls of the drawer assembly 200 and the cabinet 100.

In addition, a drawer door 202 may be disposed on the outer side of the drawer assembly 200, that is, on the side of the drawer assembly 200 facing the opening of the accommodating space 101, and when the drawer assembly 200 is closed (that is, pushed into the accommodating space 101), the drawer door 202 may abut against a side wall of the opening of the accommodating space 101, so as to improve the sealing performance of the accommodating space 101, and effectively preserve or freeze the articles in the drawer assembly 200.

Referring to fig. 1 and 2, in the embodiment of the present utility model, one end of the first link 300 is rotatably connected to the cabinet 100, and the other end of the first link 300 is rotatably connected to the drawer assembly 200; the first link 300 is slidably coupled with respect to one of the cabinet 100 and the drawer assembly 200, and the first link 300 serves to raise the horizontal height of the drawer assembly 200.

Specifically, in embodiments of the present utility model, the first link 300 may be disposed between a side wall of the drawer assembly 200 and a side wall of the case 100, and in some examples, the first link 300 may also be disposed between bottom walls of the bottom wall case 100 of the drawer assembly 200. When specifically provided, the first link 300 may be rotatably coupled to the case 100 and the drawer assembly 200 through a rotation shaft (e.g., a pin, a bolt, a rivet shaft, or the like).

It will be appreciated that, after the drawer assembly 200 is generally inserted into the accommodating space 101 of the case 100, the top of the drawer assembly 200 is blocked by the top wall of the case 100, and at this time, the first link 300 cannot be rotated. In one example of an embodiment of the present utility model, the first link 300 may be slidably coupled with the case 100. For example, a sliding rail or a sliding groove is provided on the side wall of the box 100, and the first connecting rod 300 is rotatably connected with the sliding rail or the sliding groove and slides in the sliding rail or the sliding groove; thus, when the drawer assembly 200 is pulled, the first link 300 moves along with the drawer assembly 200 and moves to the opening of the accommodating space 101, and the drawer assembly 200 is pulled continuously, because the first link 300 must slide to the end of the sliding rail, the first link cannot slide continuously at this time, and thus the first link can rotate with the sliding rail or the sliding chute, so that the horizontal position of the drawer assembly 200 is lifted, that is, the drawer assembly 200 is lifted along the vertical direction.

As a specific example, the first link 300 is provided between the drawer assembly 200 and the sidewall of the case 100; at this time, the first link 300 may be vertically or nearly vertically disposed; in addition, the bottom end of the first link 300 is connected with the first drawer assembly 200, and the top end of the first link 300 is connected with the cabinet 100; thus, after the drawer assembly 200 is pulled out of the accommodating space 101, the drawer assembly 200 is pulled continuously, the first link 300 rotates, and the connection position between the first link 300 and the case 100 is unchanged (i.e. the height of the case 100 is fixed); the first link 300 is horizontally rotated from the vertical direction, and the bottom horizontal position of the first link 300 is elevated, thereby elevating the position of the drawer assembly 200.

It is understood that the first link 300 may be slidably coupled with the drawer assembly 200 when the first link 300 is disposed between the drawer assembly 200 and the sidewall of the case 100; for example, the first link 300 may be vertically disposed at the opening of the accommodating space 101, and at this time, the first link 300 does not need to slide with the case 100, but only needs to slide with the drawer assembly 200.

In some examples, the first link 300 may also be slidably coupled to the case 100; for example, the first link 300 may be vertically disposed at an end of the drawer assembly 200 facing the inside of the receiving space 101.

As another specific example, the first link 300 is disposed between the drawer assembly 200 and the bottom wall of the case 100; at this time, the first link 300 may be horizontally or approximately horizontally disposed; in addition, one end of the first link 300 facing the inside of the receiving space 101 may be connected with the bottom of the drawer assembly 200; one end of the first link 300 facing the opening of the accommodating space 101 may be connected with the case 100; when the drawer assembly 200 is pulled, the first link 300 moves together with the drawer assembly 200, and after the drawer assembly 200 is completely pulled out of the opening of the accommodating space 101, the drawer assembly 200 is pulled continuously, and the first link 300 rotates from the horizontal direction to the vertical direction, thereby raising the position of the drawer assembly 200.

According to the storage device 10 of the embodiment of the present utility model, by providing the first link 300 between the drawer assembly 200 and the case 100, one end of the first link 300 is rotatably connected to the case 100, and the other end of the first link 300 is rotatably connected to the drawer assembly 200; and the first link 300 is slidably coupled with one of the cabinet 100 and the drawer assembly 200; thus, after the user pulls the drawer assembly 200 out of the case 100, the drawer assembly 200 is pulled continuously, and due to the existence of the first link 300, the first link 300 rotates with the case 100 and the drawer assembly 200, for example, the first link 300 rotates from vertical to horizontal, or the first link 300 rotates from horizontal to vertical, so that the horizontal position of the drawer assembly 200 can be lifted, the drawer assembly 200 is lifted, and the user can take articles conveniently; in contrast to the related art, in the embodiment of the present utility model, the drawer assembly 200 and the first link 300 have contact only at the rotation shaft, i.e., the drawer assembly 200 and the first link 300 have friction only at the rotation shaft; and the first link 300 has friction with the case 100 at the rotation shaft; therefore, the friction contact surfaces between the drawer assembly 200 and the first connecting rod 300 and between the first connecting rod 300 and the box body 100 are smaller, so that the friction force applied to the drawer assembly 200 during the high lifting process can be effectively reduced, and the drawer assembly 200 can be lifted conveniently.

With continued reference to fig. 1 and 2, in an alternative example of an embodiment of the present utility model, the storage apparatus 10 further includes a second link 400, where the second link 400 is disposed side by side with the first link 300, one end of the second link 400 is rotatably connected to the case 100, and the other end of the second link 400 is rotatably connected to the drawer assembly 200; the second link 400 is slidably coupled with respect to one of the cabinet 100 and the drawer assembly 200.

It can be appreciated that in the embodiment of the present utility model, the second link 400 may be disposed in the same manner as the first link 300; that is, when the first link 300 is disposed between the drawer assembly 200 and the sidewall of the case 100, the second link 400 may be disposed between the drawer assembly 200 and the sidewall of the case 100; when the first link 300 is disposed between the drawer assembly 200 and the bottom wall of the case 100, the second link 400 may also be disposed between the drawer assembly 200 and the bottom wall of the case 100.

When specifically provided, the first link 300 and the second link 400 may be parallel or approximately parallel to each other. In this way, a parallelogram structure, which may also be called a four-bar structure, is formed between the first link 300, the second link 400, the drawer assembly 200 and the cabinet 100, which is advantageous in improving stability when lifting the height of the drawer assembly 200.

In the embodiment of the utility model, two connecting rods, namely a first connecting rod 300 and a second connecting rod 400 which are arranged side by side are arranged; thus, the first link 300 and the second link 400 can play a role in supporting and lifting the drawer assembly 200 together in the process of pulling the drawer assembly 200 out of the case 100 and continuing to pull the drawer assembly 200; that is, the presence of two support points of the first link 300 and the second link 400 to support the drawer assembly 200 can ensure the stability of the drawer assembly 200 during the lifting of the drawer assembly 200.

Fig. 3 is another schematic structural view of a storage device according to an embodiment of the present utility model, and fig. 4 is a further side view of the storage device according to the embodiment of the present utility model.

Referring to fig. 3 and 4, the storage device 10 provided in the embodiment of the present utility model further includes: a third link 500 and a fourth link 600.

Specifically, in the embodiment of the present utility model, the third link 500 may be disposed on the case 100, for example, on a side wall or a bottom wall of the case 100. Wherein the first link 300 and the second link 400 may be rotatably connected with the third link 500.

Thus, by arranging the third connecting rod 500 on the box body 100, the first connecting rod 300 and the second connecting rod 400 are rotationally connected with the third connecting rod 500, and a rotating shaft hole is not required to be formed on the box body 100, so that the complete structure of the box body 100 can be maintained, and the heat preservation and refrigeration effect of the box body 100 can be ensured.

When the device is specifically arranged, the shaft holes can be formed at one ends of the first connecting rod 300, the second connecting rod 400 and the third connecting rod 500, the shaft rod can be arranged on the third connecting rod 500 and penetrates into the shaft holes, and therefore rotation of the first connecting rod 300, the second connecting rod 400 and the third connecting rod 500 is achieved. Of course, in some examples, the third link 500 may be correspondingly provided with a shaft hole, and the shaft pins sequentially pass through the shaft hole, so as to form a rotational connection relationship. In other examples, the third link 500 may be provided with a shaft hole, and the first link 300 and the second link 400 may be provided with shafts.
