As shown in connection with fig. 1-3, embodiments of the present disclosure provide a shelving assembly including a shelf 100 and a lifting mechanism 200.

The shelf 100 is used for placing objects. The lifting mechanism 200 is disposed at the rear end of the shelf 100, and includes a support base 210, a sliding portion 220, and a locking portion 230. The sliding part 220 includes a guide shaft 221 vertically disposed at the support base 210, and the shelf 100 is slidably coupled to the guide shaft 221 and can be raised or lowered along the guide shaft 221. The lock portion 230 is rotatably provided with respect to the slide portion 220, and the lock portion 230 can be switched between at least a lock state and a retracted state. Wherein the locking part 230 stops the sliding part 220 in a locked state to fix the shelf; when the shelf is lifted up by the operation, the locking part 230 is switched to the escape state and releases the sliding part 220 so that the shelf 100 can be lifted up or down along the guide shaft 221.

Alternatively, the shelf 100 is constructed in a flat plate shape and horizontally placed so as to facilitate placement of articles. Alternatively, the shelf 100 is a glass shelf or a resin shelf to save costs while improving the aesthetic appearance of the shelf 100.

Optionally, a lifting mechanism 200 is disposed at the rear end of the shelf 100, for driving the shelf 100 to adjust in height in the vertical direction. The elevating mechanism 200 includes a support base 210, a sliding portion 220, and a locking portion 230. The sliding portion 220 includes a guiding shaft 221 arranged vertically, which is fixedly disposed on the supporting seat 210, that is, a sliding direction defined by the guiding shaft 221 is a vertical direction. The shelf 100 is slidably coupled to the guide shaft 221 such that it can be raised or lowered in a direction defined by the guide shaft 221, thereby changing its height.

Alternatively, the locking portion 230 is rotatably provided with respect to the sliding portion 220, and the locking portion 230 is at least switchable between a locked state and a retracted state. When the locking part 230 is in the locked state, it is in stop-fit with the sliding part 220 to achieve the fixation of the shelf 100, thereby enabling the shelf 100 to be fixed to a corresponding height. When the shelf 100 is lifted up, the locking part 230 can be switched to the escape state and release the sliding part 220, the sliding part 220 evacuates the escape space, and the shelf 100 can be lifted up or down along the guide shaft 221, thereby achieving the height adjustment of the shelf 100.

Alternatively, in order to improve the stability of the shelf 100 after the height adjustment or fixation, the elevating mechanism 200 is provided with two sets, which are respectively provided at opposite side ends of the shelf 100. The embodiments of the present disclosure will be described in detail with only one side as an example.

By adopting the shelf assembly provided by the embodiment of the disclosure, the lifting of the shelf can be flexibly realized through the switching of the locking part between the locking state and the avoiding state. Wherein the locking part stops the sliding part in a locking state so as to fix the shelf at a set height; when the shelf is lifted upwards, the locking part can be switched to an avoidance state and the sliding part is released, so that the shelf can ascend or descend along the guide shaft rod on the supporting seat, and the height of the shelf is adjusted. The height adjustment of the shelf assembly is simple and convenient, a driving mechanism is not required to be arranged, the occupied space is small, the cost is low, and in addition, the shelf assembly is convenient to lift the height adjustment of the shelf, so that the utilization rate of the storage space in the refrigerator or the storage equipment is optimized.

In some embodiments, the slide 220 further includes a slide bearing 222 and a bearing housing 223. The slide bearing 222 is fitted around the outer periphery of the guide shaft 221, and the slide bearing 222 can move up and down in a direction defined by the guide shaft 221. The bearing housing 223 is fixedly sleeved on the outer circumference of the sliding bearing 222 and is fixedly connected with the shelf 100.

Alternatively, the bearing housing 223 is fixedly coupled with the shelf 100. When the shelf 100 is lifted, the bearing housing 223 moves in synchronization with the shelf 100. The bearing housing 223 is fixedly fitted around the outer periphery of the slide bearing 222, and the slide bearing 222 is fitted around the outer periphery of the guide shaft 221 so as to be movable up and down in a direction defined by the guide shaft 221. As such, when the shelf 100 is lifted, the bearing housing 223 and the shelf 100 can be moved up or down along the guide shaft 221 by the slide bearing 222.

Alternatively, in order to improve stability and ease of height adjustment of the shelf 100, the slide bearings 222 are provided in two. Optionally, the sliding bearing 222 employs a mute bearing to effectively reduce resistance of the shelf 100 during height adjustment and to reduce noise during height adjustment to improve comfort of user experience.

In some embodiments, the locking part 230 includes a rotation shaft 231, a locking hook 232, a first limit pin 233, and a second limit pin 234.

The rotating shaft 231 is fixedly disposed on the first side wall 211 of the supporting seat 210, and the first side wall 211 extends vertically. The latch hook 232 is rotatably disposed on the rotating shaft 231, and includes an inner arc surface 2321 and an outer arc surface 2322 with the same bending direction. The upper end of the inner arc surface 2321 and the upper end of the outer arc surface 2322 intersect to form a tip 2323 of the lock hook 232, and the lower end of the inner arc surface 2321 and the lower end of the outer arc surface 2322 are bent toward the tip 2323 and intersect to form a hook end 2324 of the lock hook 232. The first limiting pin 233 is fixedly disposed on the first sidewall 211 of the supporting seat 210 and located above the extrados 2322. The second limiting pin 234 is fixedly disposed on a first side surface of the bearing seat 223, and the first side surface faces the first side wall 211 of the supporting seat 210. The tip 2323 is close to the rotating shaft 231 and is located above the hook end 2324, and in the locked state, the intrados 2321 and the second limiting pin 234 form a stop fit, so that the second limiting pin 234 is hooked with the hook end 2324. When switching to the avoidance state, the outer arc surface 2322 is limited by contact with the first limiting pin 233, and the tip 2323 can rotate around the rotation shaft 231, so that the hook end 2324 is unlocked from the second limiting pin 234.

In some embodiments, one or more latch hooks 232 are spaced apart on the support along the extension direction of the guide shaft.

Alternatively, in case one latch hook 232 is provided, it may be correspondingly provided at the middle height of the guide shaft 221.

Optionally, in the case of providing a plurality of latch hooks 232, a plurality of rotating shafts 231 engaged with the latch hooks 232 and a plurality of first stopper pins 233 engaged with the latch hooks 232 are provided.

Optionally, the center of gravity of the shackle 232 is located near the lower half of the hook end 2324. As such, in a natural state, the nib 2323 is naturally located above the hook end 2324.

Optionally, as shown in fig. 5, the tip 2323 is close to the rotating shaft 231 and is located above the hooking end 2324, and in a case that a plurality of locking hooks are provided and the shelf 100 is fixed to a set height, the locking portion 230 is in a locked state, and the intrados 2321 of the corresponding locking hook 232 located at the height forms a stop fit with the second limiting pin 234. At this time, the second limiting pin 234 has a downward movement tendency under the action of gravity, and the hooking end 2324 of the latch hook 232 is in stop fit with the second limiting pin 234 to prevent the downward movement of the second limiting pin 234, so that the second limiting pin 234 is fixed to the hooking end 2324. That is, at this time, the shelf 100 is fixed to the hook end 2324 at a height, and the fixing of the shelf 100 is ensured by the engagement of the second stopper pin 234 with the hook end 2324 of the latch hook 232.

As shown in connection with fig. 6 to 9, in case that the height of the shelf 100 needs to be adjusted, the shelf 100 is lifted to apply an upward force to the shelf 100 so that the shelf 100 moves the bearing housing 223 upward. Since the second limiting pin 234 is disposed on the first side of the bearing housing 223, the second limiting pin 234 synchronously follows the upward movement of the bearing housing 223 and is disconnected from the hooking end 2324. The shelf 100 continues to be lifted such that the second spacing pin 234 continues to travel upward. After the second limiting pin 234 is in sliding contact with the inner arc surface 2321 of the tip 2323, the second limiting pin 234 continues to move upwards, the tip 2323 rotates around the rotating shaft 231 along the pointer under the pushing of the second limiting pin 234 and the limitation of the first limiting pin 233 on the outer arc surface 2322, at this time, the locking part 230 is switched to an avoiding state and releases the sliding part 220, and the locking hook 232 avoids a yielding space, so that the bearing seat 223 can continuously ascend or descend along the guiding shaft lever 221. In the case that the second stopper pin 234 is completely separated from the latch hook 232, the latch hook 232 is rotated counterclockwise by gravity and is restored to a natural state.

Further, as shown in fig. 10 to 14, after the locking portion 230 is switched to the avoidance state, that is, in a case where the second limiting pin 234 is completely separated from the locking hook 232, if the height of the shelf 100 needs to be increased, the shelf 100 is continuously lifted upwards until the second limiting pin 234 touches the hooking end 2324 of the ground locking hook 232 located at a higher position. The second limiting pin 234 is in sliding contact with the outer arc surface 2322 of the ground locking hook 232 disposed at a higher position, and under the action of an upward force, the locking hook 232 can rotate anticlockwise around the rotating shaft, so that the hooking end 2324 moves upwards relative to the rotating shaft 231, and a space is reserved for the upward movement of the second limiting pin 234. After the second limiting pin 234 moves upward to be disconnected from the hook end 2324, the latch hook 232 rotates counterclockwise under the action of gravity and returns to a natural state. At this time, the upward lifting force for the shelf 100 is removed, so that the shelf 100 moves downward until the second limiting pin 234 is in stop engagement with the hooking end 2324 of the locking hook 232. The second stopper pin 234 is engaged with the locking hook 232 at the higher position, thereby achieving the fixation of the shelf 100 at the height.

Further, as shown in fig. 15 and 16, after the locking portion 230 is switched to the avoidance state, that is, in a case where the second limiting pin 234 is completely separated from the locking hook 232, if the height of the shelf 100 needs to be reduced, the shelf 100 is moved downward until the second limiting pin 234 contacts with the tip of the locking hook 232 after the locking hook 232 rotates counterclockwise under the action of gravity and returns to the natural state. At this time, the second limiting pin 234 is in sliding contact with the outer arc surface 2322 of the latch hook 232, and the second limiting pin 234 continuously moves downward, forcing the latch hook 232 to rotate counterclockwise around the rotation shaft 231, so that the latch hook 232 can make room for the downward movement of the second limiting pin, i.e., the bearing seat 223 and the shelf 100. Optionally, under the condition that the outer arc surface 2322 is in sliding contact with the first limiting pin 233, the latch hook 232 can stop rotating under the clamping of the first limiting pin 233 and the rotating shaft 231, so as to avoid the latch hook 232 from continuously rotating anticlockwise under the action of inertia to affect the downward movement of the shelf 100. Further, in case that the second stopper pin 234 moves downward to be completely separated from the latch hook 232, the latch hook 232 rotates counterclockwise and returns to a natural state by the gravity. When the second stopper pin 234 moves downward to contact the tip 2323 of the locking hook 232 at a lower position, at this time, the second stopper pin 234 is in sliding contact with the outer arc surface 2322 of the locking hook 232 at the lower position, the second stopper pin 234 continues to move downward, forcing the locking hook 232 to rotate counterclockwise about the rotation shaft 231, thereby allowing the locking hook 232 to make room for the downward movement of the second stopper pin, i.e., the bearing housing 223 and the shelf 100. After the second stopper pin 234 is lowered to the lower position, the shelf 100 is lifted up again to move the second stopper pin 234 upward. As shown in fig. 11 to 14, when the second limiting pin 234 contacts the hooking end 2324 of the ground locking hook 232 disposed at a lower position and is in sliding contact with the outer arc surface 2322 of the locking hook 232, the locking hook 232 can rotate counterclockwise around the rotating shaft under the upward force, so that the hooking end 2324 moves upward relative to the rotating shaft 231 and a space is reserved for the upward movement of the second limiting pin 234. After the second limiting pin 234 moves upward to be disconnected from the hook end 2324, the latch hook 232 rotates counterclockwise under the action of gravity and returns to a natural state. At this time, the upward lifting force for the shelf 100 is removed, so that the shelf 100 moves downward until the second limiting pin 234 is in stop engagement with the hooking end 2324 of the locking hook 232. The second stopper pin 234 is engaged with the locking hook 232 at the higher position, thereby achieving the fixation of the shelf 100 at the height.

Optionally, in the case where one latch hook 232 is provided, when the shelf 100 is fixed to the height of the latch hook 232, as shown in fig. 5, the locking portion 230 is in the locked state, and the intrados 2321 of the latch hook 232 forms a stop fit with the second limiting pin 234. At this time, the second limiting pin 234 has a downward movement tendency under the action of gravity, and the hooking end 2324 of the latch hook 232 is in stop fit with the second limiting pin 234 to prevent the downward movement of the second limiting pin 234, so that the second limiting pin 234 is fixed to the hooking end 2324. That is, at this time, the shelf 100 is fixed to the hook end 2324 at a height, and the fixing of the shelf 100 is ensured by the engagement of the second stopper pin 234 with the hook end 2324 of the latch hook 232.

Further, as shown in connection with fig. 6 to 9, when it is desired to adjust the shelf 100 to the bottom end of the guide shaft 221, the shelf 100 is lifted to apply an upward force to the shelf 100, so that the shelf 100 moves the bearing housing 223 upward. Since the second limiting pin 234 is disposed on the first side of the bearing housing 223, the second limiting pin 234 synchronously follows the upward movement of the bearing housing 223 and is disconnected from the hooking end 2324. The shelf 100 continues to be lifted such that the second spacing pin 234 continues to travel upward. After the second limiting pin 234 is in sliding contact with the inner arc surface 2321 of the tip 2323, the second limiting pin 234 continues to move upwards, the tip 2323 rotates clockwise around the rotating shaft 231 under the pushing of the second limiting pin 234 and the limitation of the first limiting pin 233 on the outer arc surface 2322, at this time, the locking part 230 is switched to an avoiding state and releases the sliding part 220, and the locking hook 232 avoids a yielding space, so that the bearing seat 223 can descend along the guiding shaft lever 221. In the case that the second stopper pin 234 is completely separated from the latch hook 232, the latch hook 232 is rotated counterclockwise by gravity and is restored to a natural state.

Optionally, in the case of providing one latch hook 232, as shown in fig. 10 to 14, when the shelf 100 is fixed to the bottom end of the guide shaft 221 and needs to be moved up to the height of the latch hook 232, the shelf 100 is lifted up until the second limiting pin 234 contacts the hooking end 2324 of the latch hook 232. The second limiting pin 234 is in sliding contact with the outer arc surface 2322 of the locking hook 232, and under the action of the upward force, the locking hook 232 can rotate anticlockwise around the rotating shaft, so that the hooking end 2324 moves upwards relative to the rotating shaft 231, and a space is reserved for the upward movement of the second limiting pin 234. After the second limiting pin 234 moves upward to be disconnected from the hook end 2324, the latch hook 232 rotates counterclockwise under the action of gravity and returns to a natural state. At this time, the upward lifting force for the shelf 100 is removed, so that the shelf 100 moves downward until the second limiting pin 234 is in stop engagement with the hooking end 2324 of the locking hook 232. The second stopper pin 234 is engaged with the locking hook 232, thereby achieving the fixation of the shelf 100 at this height.
