[0039] Participation Figure 1 , Figure 2The utility model discloses first aspect embodiment proposed shelf 10, including drive assembly 100, transmission assembly 200, thing board subassembly, movable support 300, guide rail 400 and gyro wheel 500, movable support 300 is connected with thing board subassembly, drive assembly 100 includes drive piece 110 and with drive piece 110 transmission connection's transmission shaft 120, transmission assembly 200 includes disc 210 and flexible cable 240, disc 210 is provided with two, two disc 210 sets up in the left and right sides of shelf 10, transmission shaft 120 is connected with two disc 210, and flexible cable 240 is correspondingly provided with two, and the first end of flexible cable 240 is connected with corresponding disc 210, and movable support 300 is connected with the second end of flexible cable 240. When drive piece 110 drives disc 210 to rotate to the positive rotation direction, flexible cable 240 is wound on the mounting portion of disc 210, and flexible cable 240 drives movable support 300 to move upwards;When drive piece 110 drives disc 210 to rotate to the reverse direction, flexible cable 240 is released from the mounting portion, and movable support 300 moves downwards under the gravity of itself and thing board subassembly, thereby driving thing board subassembly to move up and down. Thus, the shelf 10 of the utility model can adjust the position of the thing board subassembly along the vertical direction, meet the needs of placing different height food, improve the user experience, and enhance the product competitiveness.

[0040] In the embodiment, the up-down movement of the movable support 300 is realized by the structure of the guide rail 400 and the gyro wheel 500. Specifically, referring to Figure 5 、 Figure 6 , the guide rail 400 is an integral structure, which can be processed by stamping process, and has a first wall 410, a second wall 420 and a third wall 430 extending along the length direction. The one side of the third wall 430 in the width direction is connected with the first wall 410, and the other side of the third wall 430 in the width direction is connected with the second wall 420. The first wall 410 and the second wall 420 are oppositely arranged and extend away from the third wall 430. The first wall 410, the second wall 420 and the third wall 430 enclose a track, and the side of the third wall 430 facing the track is a plane. The gyro wheel 500 is arranged in the track, and the wheel surface of the gyro wheel 500 is opposite to the first wall 410 and the second wall 420. The end surface of the gyro wheel 500 is opposite to the third wall 430. The gyro wheel 500 has a rotating shaft 510, and the end of the rotating shaft 510 away from the gyro wheel 500 is connected with the movable support 300. The rotating shaft 510 is not only the connecting piece of the gyro wheel 500 and the movable support 300, but also the rotating shaft of the gyro wheel 500. The connecting structure of the gyro wheel 500 and the movable support 300 is simplified, and when the movable support 300 moves relative to the guide rail 400, the gyro wheel 500 can form a combined movement of rolling and sliding in the track.

[0041] Specifically, the wheel surface of the roller 500 has a predetermined gap between the first wall 410 and the second wall 420, when the driving assembly 100 drives the movable support 300 to move up and down, the wheel surface of the roller 500 can be in contact with the first wall 410 or the second wall 420, or can not be in contact with the first wall 410 or the second wall 420.

[0042] When the wheel surface of the roller 500 is in contact with the first wall 410 or the second wall 420, the roller 500 is rolled by the friction between the first wall 410 or the second wall 420 and the roller 500, and the first wall 410 and the second wall 420 are also used to limit the movement track of the roller 500 along the width direction of the track; when the wheel surface of the roller 500 is not in contact with the first wall 410 or the second wall 420, the movement of the roller 500 in the guide rail is sliding, therefore, the movement of the roller 500 in the guide rail 400 is a mixed type of rolling and sliding, the roller 500 has good adaptability with the guide rail 400, and runs stably.

[0043] Therefore, the shelf 10 of the embodiment of the utility model adopts the structure that the integrally formed guide rail 400 cooperates with the roller 500, which can realize the linear motion function, has simple structure, fewer parts, and thus lower cost, and the movement of the roller 500 in the guide rail 400 is a mixed form of rolling and sliding, has good adaptability, can reduce the movement resistance of the roller 500 in the guide rail 400, makes the roller 500 run stably and reliably, and can improve the service life.

[0044] In some embodiments, the roller 500 can be made of plastic material, which can further reduce the production cost, and the roller 500 made of plastic has good flexibility, the contact between the roller 500 and the guide rail 400 is softer, which can improve the service life of the guide rail 400 and the roller 500, thereby reducing the maintenance frequency of the shelf 10 and improving the use stability of the shelf 10.

[0045] Referring to Figure 6 In some embodiments, one side of the first wall 410 facing the second wall 420 is provided as an arc surface, correspondingly, one side of the second wall 420 facing the first wall 410 is provided as an arc surface, and the wheel surface of the roller 500 is provided as a shape matched with the arc surface, thereby the arc surface of the guide rail 400 and the arc wheel surface of the roller 500 cooperate to produce the effect of automatically adjusting the movement center of the roller 500, which plays a role of correcting the deviation of the roller 500, can better accommodate the error generated by the roller 500 in the linear motion, avoids the movement of the roller 500 being blocked by the guide rail 400, makes the roller 500 run stably in the guide rail 400, and improves the reliability of the position adjustment of the shelf 10.

[0046] Therefore, referring to Figure 7In some embodiments, the end face of the roller 500 facing the third wall 430 is provided with a groove 520 extending from a position close to the middle of the end face of the roller 500 to the wheel surface of the roller 500 in the radial direction of the roller 500. Specifically, in the embodiment shown in the figure, a plurality of grooves 520 are provided, and the plurality of grooves 520 are arranged in the circumferential direction of the end face of the roller 500, forming a petal shape. When the roller 500 cooperates with the guide rail 400, the grooves 520 can be filled with lubricating grease. When the roller 500 rotates, the side wall of the groove 520 continuously stirs the lubricating grease, so as to achieve better lubrication effect, thereby adjusting the friction between the roller 500 and the guide rail 400 in the sliding process, and making the roller 500 run smoothly.

[0047] In some embodiments, the end of the rotating shaft 510 away from the roller 500 is connected to the movable support 300 by a riveting process, so that the connection between the roller 500 and the movable support 300 is stable and compact.

[0048] It should be noted that the connection between the rotating shaft 510 and the movable support 300 can also be achieved by thread connection, fastener connection, etc., which is not limited herein.

[0049] Referring to Figure 5 , Figure 6 In some embodiments, the guide rail 400 is provided with an opening 440 at both ends, through which the roller 500 can be conveniently assembled into the guide rail 400. A plugging member 450 is installed at the opening 440, and the plugging member 450 is connected to the guide rail 400 by a fastener. The plugging member 450 can prevent the roller 500 from falling out of the guide rail 400 during movement.

[0050] Referring to Figure 3 , Figure 4 In some embodiments, the disc body 210 is provided with a first guide structure 600 and a second guide structure 700. The first guide structure 600 includes a first accommodating cavity 610 and a first guide groove 620. The first guide groove 620 has a first port and a second port. The first port communicates with the first accommodating cavity 610, and the second port communicates with the outside of the disc body 210. The second guide structure 700 includes a second accommodating cavity 710 and a second guide groove 720. The second guide groove 720 has a third port and a fourth port. The third port communicates with the second accommodating cavity 710, and the fourth port communicates with the outside of the disc body 210. The opening direction of the second port of the first guide groove 620 is opposite to the opening direction of the fourth port of the second guide groove 720 in the circumferential direction of the disc body 210, i.e., the guide direction of the first guide groove 620 to the flexible cable 240 is opposite to the guide direction of the second guide groove 720 to the flexible cable 240.

[0051] The first end of the flexible cable 240 is adapted to be fixed in the first accommodating cavity 610 or the second accommodating cavity 710, and the second end of the flexible cable 240 is adapted to pass through the corresponding first guide slot 620 or the second guide slot 720 and then be wound on the mounting portion of the disc body 210. Specifically, when the disc body 210 is installed on the left side of the shelf 10, the first end of the flexible cable 240 is fixed in the first accommodating cavity 610, the second end of the flexible cable 240 passes through the first guide slot 620 and is wound on the mounting portion of the disc body 210 in the direction of the forward rotation of the driving member 110; when the disc body 210 is installed on the right side of the shelf 10, the first end of the flexible cable 240 is fixed in the second accommodating cavity 710, and the second end of the flexible cable 240 passes through the second guide slot 720 and is wound on the mounting portion of the disc body 210 in the direction of the forward rotation of the driving member 110.

[0052] In the above embodiment, the mounting portion includes the recess 250 which is arranged on the outer circumferential surface of the disc body 210.

[0053] By arranging the first guide slot 620 and the second guide slot 720 with opposite guide directions on the disc body 210, for the installation position of the disc body 210, the flexible cable 240 can selectively pass through the first guide slot 620 or the second guide slot 720 to change the winding direction of the flexible cable 240. When the disc body 210 is used on both sides of the shelf 10, by changing the winding direction of the flexible cable 240, the second end of the flexible cable 240 on both sides of the shelf 10 extends from the same side of the shelf 10, so that the flexible cable 240 between the movable support 300 and the disc body 210 on both sides of the shelf 10 extends in the vertical direction, avoiding the inclination of the flexible cable 240, avoiding the interference between the flexible cable 240 and other components, and thus balancing and stabilizing the up-down movement of the shelf 10. Therefore, the disc body 210 has universality and can be used on both sides of the shelf 10, thereby reducing the number of parts of the shelf 10 and reducing the assembly cost.

[0054] It should be noted that the flexible cable 240 includes but is not limited to a steel wire rope, a rope, a steel wire or a chain, etc., and the side wall of the recess 250 is used to limit the flexible cable 240, so as to ensure that the flexible cable 240 can be wound in the recess 250 when the disc body 210 rotates in the forward direction.

[0055] Referring to Figure 4In some embodiments, the first guide groove 620 and the second guide groove 720 are symmetrically arranged, specifically, in the embodiment shown in the figure, the first guide groove 620 and the second guide groove 720 are symmetrically arranged in the up-down direction relative to the radial direction of the horizontal direction of the disc body 210, so that when the disc body 210 is installed on the left side of the shelf 10, the disc body 210 is assembled to the transmission shaft 120 in the normal state, and when the disc body 210 is installed on the right side of the shelf 10, the disc body 210 is only rotated by 180° and then assembled to the transmission shaft 120, so that the purpose of changing the winding direction of the flexible cable 240 is achieved, and the second ends of the flexible cables 240 on both sides of the shelf 10 are stretched out from the same side of the shelf 10.

[0056] In some embodiments, the disc body 210 is made of plastic material, so that the contact between the disc body 210 and other cooperating parts during rotation is relatively soft, especially the contact between the flexible cable 240 and the disc body 210 is softer, which can reduce the friction between the disc body 210 and the flexible cable 240, thereby reducing the damage to the flexible cable 240 and other cooperating parts, and at the same time, the noise of the shelf 10 during operation can be reduced, which is beneficial to improve the use experience of the storage cabinet using the shelf 10.

[0057] Referring to Figure 4 In some embodiments, the first guide groove 620 and the second guide groove 720 are both arc-shaped grooves, which can make the winding and turning of the flexible cable 240 smooth and transition, avoid the phenomenon that the flexible cable 240 is worn and broken due to stress concentration during winding along the disc body 210, improve the winding and turning load capacity of the flexible cable 240, prolong the winding and turning life of the flexible cable 240, and improve the reliability of the connection between the flexible cable 240 and the disc body 210.

[0058] Referring to Figure 4 In some embodiments, the disc body 210 is provided with a first through hole 230 in the thickness direction, the first through hole 230 is in communication with the accommodating cavity, and the first end of the transmission shaft 120 is inserted into the first through hole 230. The disc body 210 is a circular disc body 210, and the center of the first through hole 230 coincides with the center of the disc body 210. Moreover, the first port of the first guide groove 620 is in communication with the first accommodating cavity 610 through the first through hole 230, and the third port of the second guide groove 720 is in communication with the second accommodating cavity 710 through the first through hole 230.

[0059] Referring to Figure 3In some embodiments, the first end of the transmission shaft 120 is provided with a limiting portion 121 abutting against the first side of the disc body 210 and a locking member 122 abutting against the second side of the disc body 210. Since the disc body 210 is located between the limiting portion 121 and the locking member 122, the limiting portion 121 and the locking member 122 can connect the disc body 210 to the first end of the transmission shaft 120 and prevent the disc body 210 from moving along the axial direction of the transmission shaft 120. Locking the disc body 210 by using the locking member 122 can simplify the mounting and dismounting steps of the disc body 210.

[0060] With reference to Figure 3 In some embodiments, the first end of the transmission shaft 120 is provided with a second through hole 123, the locking member 122 is inserted into the second through hole 123, and the limiting portion 121 includes a limiting step provided at the first end of the transmission shaft 120. The limiting step is provided with two limiting steps which are symmetrically arranged. After the limiting step is provided, no other limiting portion 121 is needed, thereby reducing the number of components of the disc body 210 and simplifying the structure of the disc body 210.

[0061] It should be noted that at least one flat surface can be milled on the outer circumferential surface of the first end of the transmission shaft 120 by using a machining device, so that the limiting step is formed on the outer circumferential surface of the first end of the transmission shaft 120.

[0062] In some embodiments, the locking member 122 is configured as a bayonet which, after being inserted into the second through hole 123, clamps the first end of the transmission shaft 120 by using the clamping portion of the bayonet. The bayonet can not only lock the disc body 210 but also lock itself, thereby preventing the bayonet from falling off during the rotation of the disc body 210. In addition, the bayonet can facilitate the mounting and dismounting of the disc body 210.

[0063] It should be noted that the locking member 122 can also be a pin, a nut, a key pin, etc. When the pin, the nut or the key pin is used as the locking member 122, a corresponding through hole, a thread or a key groove needs to be provided at the corresponding position of the first through hole 230 or the transmission shaft 120, which will not be described in detail herein.

[0064] In some embodiments, the first through hole 230 is a non-circular hole, and the cross-sectional shape of the first end of the transmission shaft 120 is adapted to the shape of the first through hole 230. By setting the first through hole 230 as a non-circular hole, the disc body 210 can be prevented from rotating relative to the transmission shaft 120 after the transmission shaft 120 is inserted into the first through hole 230.

[0065] It can be understood that the non-circular hole can be a waist-shaped hole, an elliptical hole, a rectangular hole, a triangular hole, etc.

The first disc body 211 and the second disc body 212 are both circular disc bodies 210, and the diameter of the first disc body 211 is equal to the diameter of the second disc body 212. The recess 250 is formed at the connection between the outer circumferential surface of the first disc body 211 and the outer circumferential surface of the second disc body 212. In the present embodiment, the side of the second disc body 212 facing the first disc body 211 is provided with a protruding portion 2121, the size of the protruding portion 2121 is smaller than the diameter of the second disc body 212, and when the first disc body 211 and the second disc body 212 are assembled together, the first disc body 211, the second disc body 212 and the protruding portion 2121 enclose the recess 250, so as to wind the cable 240.

[0070] Referring to Figure 3The first end of the transmission shaft 120 is provided with an axially extending clamping groove 124, a positioning head 241 is arranged in the accommodating cavity, the width of the positioning head 241 is greater than the slot width of the clamping groove 124, and the first end of the flexible cable 240 is connected to the positioning head 241 after passing through the clamping groove 124. The clamping groove 124 can not only allow the first end of the flexible cable 240 to pass through, but also limit the positioning head 241, so as to realize the connection of the first end of the flexible cable 240 to the first accommodating cavity 610 or the second accommodating cavity 710. Moreover, the clamping groove 124 limits the positioning head 241, so that a separate component is not needed to fix the positioning head 241, thereby reducing the number of components. In addition, the clamping groove 124 can also play a role in avoiding the flexible cable 240, so that the flexible cable 240 can extend from the first accommodating cavity 610 or the second accommodating cavity 710 to the corresponding first guide groove 620 and the second guide groove 720.

[0071] With reference to Figure 4 The second disc body 212 is provided with threaded holes 2122 in the thickness direction of the second disc body 212. Four threaded holes 2122 are arranged in a square shape. The first disc body 211 is provided with two through holes 2112 which penetrate the first disc body 211 in the thickness direction of the first disc body 211. The two through holes 2112 are opposite to the threaded holes 2122 at the diagonal positions of the second disc body 212.

[0072] When the disc body 210 is installed on the left side of the shelf 10, the screws pass through the two through holes 2112 and are screwed with the threaded holes 2122 at the diagonal positions of the second disc body 212, so as to fixedly connect the first disc body 211 and the second disc body 212 and make the mounting port 2111 communicate with the first accommodating cavity 610. When the disc body 210 is installed on the right side of the shelf 10, the second disc body 212 is rotated by 180°, the screws pass through the two through holes 2112 and are screwed with the threaded holes 2122 at the other diagonal positions of the second disc body 212, so as to fixedly connect the first disc body 211 and the second disc body 212 and make the mounting port 2111 communicate with the second accommodating cavity 710. Therefore, the disc body 210 can be installed on the left side of the shelf 10 and also can be installed on the right side of the shelf 10, which has universality, thereby reducing the number of components of the shelf 10 and lowering the assembly cost.

[0073] It should be noted that the number of the through holes 2112 can be the same as the number of the threaded holes 2122, as long as the through holes 2112 can be opposite to the corresponding threaded holes 2122 after the second disc body 212 is rotated by a predetermined angle, so that the screws can be screwed with the corresponding threaded holes 2122.

[0074] It can be understood that the transmission mechanism can also use a lead screw transmission or other transmission mechanisms, which are not limited here.
