Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shelves, in particular to a multifunctional shelf. BACKGROUND

[0002] With the rapid development of modern industry, the substantial increase in the flow of goods not only requires an increase in the number of shelves, but also requires the shelves to be adjustable to accommodate goods of different heights. However, in the traditional shelves, the partitions are fixed on the columns, and the height between each layer of partitions is fixed. However, in practice, the height of goods varies, which results in low space utilization of the shelves and poor flexibility, making it inconvenient to store and manage goods uniformly.

[0003] To solve the above problems, the patent with publication date CN111498361A provides a climbing type layer height adjusting storage shelf and a control method thereof. The layer shelf of the storage shelf is installed on a rectangular frame through a positioning mechanism and a climbing mechanism. The positioning mechanism can stably support the layer shelf on the rectangular frame, and the climbing mechanism can adjust the height of the layer shelf. Through the cooperation of the positioning mechanism and the climbing mechanism, the height adjustment and positioning support of each layer of the layer shelf can be realized.

[0004] However, the above structure still has the following problems:

[0005] 1. When the shelf needs to be transported, the goods inside the shelf are easily shaken or even dropped during transportation, which may damage the goods.

[0012] A stopper is mounted on each side of the rectangular frame to prevent the goods from falling, the pressing piece is movably connected to any stopper and can rotate relative to the stopper, and the pressing piece can move vertically to press the goods downward.

[0013] When the goods are high, the slidable connecting piece is used to unlock the two layer plates, then the two layer plates are rotated until the partition plate is fully opened to increase the internal storage space, the pressing piece at the bottom of the goods is rotated to be collected between the two adjacent longitudinal frames to avoid interference when the goods are put in, then the pressing piece at the top of the goods is moved downward to press one end of the pressing piece against the goods to prevent the goods from moving up and down, when the goods are small, the goods are directly put on the partition plate and the pressing piece is moved to press the goods against the partition plate, at this time, the goods are more stable in the vertical limiting of the pressing piece, the horizontal limiting of the stoppers on the left and right sides of the rectangular frame and the vertical limiting of the stoppers at the front and rear ends of the rectangular frame.

DETAILED DESCRIPTION

[0035] The technical solutions in the present application will be further described below in combination with the drawings and embodiments.

[0036] In combination with Figure 1 and Figure 2 shown, the embodiment of the present application proposes a multifunctional shelf, comprising: a rectangular frame 4, a partition 1, a compression member 2 and a connecting member 3, wherein,

[0037] The rectangular frame 4 comprises a plurality of transverse frames 401, longitudinal frames 402 and vertical frames 403 (the three are perpendicular to each other) connected end to end, in order to further facilitate the staff to transport the shelf, the bottom of the rectangular frame 4 is provided with a roller 16;

[0038] The partition 1 comprises a left layer plate and a right layer plate, wherein the left end of the left layer plate is connected to the longitudinal frame 402 on the left side of the rectangular frame 4 in a longitudinal rotating manner, the right end of the right layer plate is connected to the longitudinal frame 402 on the right side of the rectangular frame 4 in a longitudinal rotating manner, the free ends of the left layer plate and the right layer plate are both provided with a slide, when the left layer plate and the right layer plate are rotated to be in the same horizontal plane, the connecting member 3 can slide in the above slides to be fixedly connected or separated from the layer plates, the partition 1 can be provided with a plurality of partitions to divide the inside of the rectangular frame 4 into a plurality of layers, in the embodiment, the partition 1 is provided with three partitions, and the three partitions 1 divide the inside of the rectangular frame 4 into four storage spaces;

[0039] The rectangular frame 4 is provided with a stopper 5 on each side to prevent the goods from falling, and each layer pressing part 2 is movably connected to any stopper 5 and can rotate relative to the stopper 5, and each layer pressing part 2 can be vertically moved to press the top of each layer of goods.

[0040] The above scheme has the following advantages:

[0041] When the goods are high, the slidable connecting part 3 is used to unlock two layer plates, and then the two layer plates are rotated downward until the layer partition 1 is completely opened to increase the internal storage space; the pressing part 2 at the bottom of the goods is rotated to be collected between the longitudinal frames 402 to avoid interference when the goods are put in, and then the pressing part 2 at the top of the goods is moved downward to press one end of the pressing part 2 against the goods to prevent the goods from moving up and down; when the goods are small, the goods are directly put on the layer partition 1, and the pressing part 2 is moved to press the goods on the layer partition 1; at this time, the goods are more stable in the vertical limiting of the pressing part 2, the horizontal limiting of the stoppers 5 on the left and right sides of the rectangular frame 4, and the vertical limiting of the stoppers 5 at the front and rear ends of the rectangular frame 4.

[0042] Another embodiment of the present application is provided, which is shown in Figure 1 , Figure 2 and Figure 6 The stopper 5 at the front end of the rectangular frame 4 is vertically extended to form a rotating rod 6, and a plurality of auxiliary limiting rods 7 extending transversely are fixed on the side wall of the rotating rod 6; in this embodiment, the number of the auxiliary limiting rods 7 is the same as that of the layer partitions 1, and when each layer partition 1 is in a horizontal position, the auxiliary limiting rod 7 is at the same horizontal height as the layer partition 1, and at this time, the auxiliary limiting rod 7 does not hinder the observation of the goods; when the goods are high, the layer partition 1 needs to be rotated downward to put in the goods, and at this time, the auxiliary limiting rod 7 is not blocked by the layer partition 1, and at this time, the auxiliary limiting rod 7 can serve as a limiting part to increase the limiting effect of the front end surface on the high part of the goods; one end of each auxiliary limiting rod 7 away from the rotating rod 6 is vertically rotatably connected to the same vertical frame 403, and a limiting block is installed on the rotating rod 6 to prevent it from rotating randomly; in this embodiment, considering that the goods in the warehouse are stacked too much, the swing amplitude of the rotating rod 6 is minimized to prevent unnecessary collision with other goods when the rotating rod 6 is rotated, and the limiting effect of the rotating rod 6 on the goods is enhanced, and the rotating rod 6 can be provided with two, and the two rotating rods 6 are symmetrically distributed along the vertical center line of the front end surface of the rectangular frame 4, and a space is left between the two rotating rods 6 to reduce the rotating radius of the rotating rod 6.

[0043] Another embodiment of the present application is provided, which is shown in Figure 1 , Figure 2 , Figure 6 and Figure 7As shown in the figure, the front end surface of the rectangular frame 4 is provided with an ear 8, and the limiting block includes a connecting rod 9 vertically and elastically connected to the rotating rod 6. The connecting rod 9 can be vertically slid into the ear 8 to limit the continuous rotation of the rotating rod 6. When the connecting rod 9 slides into the ear 8, the rotating rod 6 is limited by the ear 8 to close the front end surface of the rectangular frame 4. After the staff overcomes the elastic force to slide the connecting rod 9 until the connecting rod 9 is separated from the ear 8, the rotating rod 6 can be rotated to open the inside of the rectangular frame 4. In this embodiment, the connecting rod 9 is sleeved in the rotating rod 6, and the connecting rod 9 is elastically connected to the rotating rod 6 through a spring. The spring is vertically sleeved between the connecting rod 9 and the rotating rod 6, and the two ends of the spring are fixedly connected to the rotating rod 6 and the connecting rod 9, respectively. The end of the connecting rod 9 away from the ear 8 extends transversely and penetrates through the rotating rod 6 to form a handle 15. The rotating rod 6 is also provided with a slot for the vertical sliding of the handle 15. The vertical sliding of the handle 15 can drive the connecting rod 9 to exit the ear 8 to unlock the rotating rod 6 so that it can be freely rotated.

[0044] Another embodiment of the present application is provided. The top and bottom of the front end surface of the rectangular frame 4 are provided with ears 8. The connecting rod 9 in the same rotating rod 6 can be provided with two upper and lower connecting rods 9. The two connecting rods 9 are symmetrically distributed about the horizontal center line of the front end surface of the rectangular frame 4. The spring on the upper connecting rod 9 can push the upper connecting rod 9 upward into the ear 8 on the top of the rectangular frame 4. The spring on the lower connecting rod 9 can push the lower connecting rod 9 downward into the ear 8 on the bottom of the rectangular frame 4. In this structure, the same side rotating rod 6 is limited by the upper and lower connecting rods 9, which enhances the limiting effect. At the same time, since the two handles 15 are on the opposite ends of the two connecting rods 9 (close to each other), the staff only needs to pinch the two handles 15 and move them towards each other with one hand to simultaneously drive the two connecting rods 9 to slide out of the ear 8 to unlock the rotating rod 6, which is very convenient to operate.

[0045] Another embodiment of the present application is provided. As shown in Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , each layer plate includes a support vertical frame 101 and two support horizontal frames 102. One end of each support horizontal frame 102 is longitudinally and rotationally connected to the vertical frame 402. The two ends of the support vertical frame 101 are fixedly connected to the support horizontal frames 102. At this time, the two support horizontal frames 102 and the support vertical frame 101 are in "H" shape. In this structure, the stable support of the goods can be achieved by fewer frames, which further simplifies the internal structure.

[0046] Each support horizontal frame 102 is provided with a slide. The opposite ends of each slide are open. The slide opening in the left layer plate faces right, and the slide opening in the right layer plate faces left.

[0047] Two connecting pieces 3 are provided, and the two connecting pieces 3 are transversely and slidingly connected in the two sliding channels of any layer plate, in the embodiment, the two connecting pieces 3 are transversely and slidingly connected in the two sliding channels of the left layer plate, the right ends of the two connecting pieces 3 can be transversely and slid into the sliding channels of the other layer plate through the above-mentioned openings, the two connecting pieces 3 are fixedly connected through the longitudinal connecting rod 10, the left layer plate and the right layer plate are provided with avoiding grooves for avoiding the transverse sliding of the connecting rod 10, in the structure, when the left layer plate and the right layer plate are in the horizontal state, the right ends of the connecting pieces 3 are inserted into the sliding channels of the right layer plate by sliding the connecting rod 10 to the right, so that the left layer plate and the right layer plate are fixedly connected to place the goods, since there is always a downward pressure of the goods on the partition plate 1, the pressure is transmitted to the connecting pieces 3, so that the connecting pieces 3 are more stably connected with the layer plates and are not easy to slide (of course, in order to further enhance the connection stability of the connecting pieces 3, springs can also be installed in the sliding channels of the left layer plate, the springs extend towards the opening direction, and the two ends of the springs are connected with the left end of the sliding channel and the left end of the connecting piece 3, the springs press the connecting pieces 3 against the sliding channels of the right layer plate); the connecting rod 10 is slid to the left until the right ends of the connecting pieces 3 are separated from the right layer plate, so that the left layer plate and the right layer plate are separated from each other, and then the left layer plate and the right layer plate are rotated to expand the storage space of the layer in the rectangular frame 4.

[0048] Another embodiment is provided in the present application, as shown in Figure 1 , Figure 2 , Figure 3 The stopper 5 connected with the pressing piece 2 vertically extends to form a threaded rod 11, the pressing piece 2 is threadedly connected with the threaded rod 11, and one end of the pressing piece 2 extends radially along the threaded rod 11, in the structure, the pressing piece 2 is rotated until the extending direction of the pressing piece 2 is parallel to the extending direction of the longitudinal frame 402, at this time, the pressing piece 2 can be most compacted between the upper and lower longitudinal frames 402 without affecting the normal taking and placing of the goods; at the same time, the pressing piece 2 can be slowly and downwardly rotated to press the goods to prevent shaking, and the self-locking property of the threaded rod 11 can also prevent the pressing piece 2 from randomly sliding upwardly and downwardly after pressing the goods; through the arrangement of the threaded rod 11, the rotation, vertical movement and anti-sliding functions of the pressing piece 2 are achieved, and the internal structure of the goods shelf is further simplified.

[0049] Another embodiment is provided in the present application, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a clamping block 12 is also threadedly connected to the threaded rod 11. The clamping block 12 is located below the clamping member 2 in the same layer. At least one end of the clamping block 12 extends radially along the threaded rod 11. In this embodiment, one end of the clamping block 12 extends radially along the threaded rod 11 to form a rectangular sheet-like structure, and this end is covered with rubber. In this structure, when the width of the goods is large, the clamping block 12 is rotated to make it parallel to the left end face of the rectangular frame 4 (the clamping block 12 is sheet-like, such as...). Figure 3 As shown, parallel here means that the largest surface of the clamping block 12 is parallel to the left end face of the rectangular frame 4. At this time, the wall surface of the clamping block 12 can act as an auxiliary lateral limiting mechanism for the goods (at this time, the main lateral limiting mechanism is still the threaded rod 11). When the width of the goods is small, rotate the clamping block 12 until its rubber end faces the goods. At this time, the end is inserted into the rectangular frame 4 to act as the main lateral limiting mechanism. The clamping block 12 can further reduce the lateral movement space of the goods (compared to not setting the clamping block 12) to further enhance the stability of the goods transportation.

[0050] The two ends of the threaded rod 11 are respectively fixed on the top and bottom longitudinal frames 402 on this side, and the threaded rod 11 passes through the other longitudinal frames 402 on this side.

[0051] Both the connecting rod 10 and the partition 1 are provided with grooves 13 for engaging the threaded rod 11. When the connecting rod 10 and the partition 1 rotate downwards, they can engage with the threaded rod 11 through the grooves 13 to prevent the connecting rod 10 and the partition 1 from shaking arbitrarily during transportation. At the same time, since the partition 1 can continue to swing downwards after it contacts the threaded rod 11 until the grooves 13 engage with the threaded rod 11, this structure can further increase the maximum swing amplitude of the connecting rod 10 and the partition 1. This allows the partition 1 to swing to a vertical state even when the vertical thickness of the partition 1 is the same as the horizontal width of the vertical frame 403, so that it can be contained between the upper and lower vertical frames 402 without affecting the normal loading and unloading of goods. When the goods are high, after the partition 1 swings to a vertical state, the supporting horizontal frames 102 and supporting vertical frames 101 of the left and right layers, together with the threaded rod 11, can act as a lateral limiting mechanism to restrict the lateral sliding of the goods, further enhancing the lateral limiting effect of this rectangular frame 4.

[0052] Combination Figure 1 and Figure 5 As shown, the width of the clamping block 12 and the clamping member 2 is smaller than the lateral width of the longitudinal frame 402, so that rotating the clamping block 12 and the clamping member 2 can completely retract them between the longitudinal frames 402 on the same side.

[0053] This invention proposes another embodiment, such as... Figure 3As shown, considering that the threaded rod 11 is provided with multiple clamping blocks 12 and pressing members 2, and the threaded rod 11 passes through part of the longitudinal frame 402, for the convenience of installation of the longitudinal frame 402, multiple mounting holes are reserved on each vertical frame 403, and the longitudinal frame 402 is longitudinally and threadedly connected with fixing rods 14 at both ends, and the opposite ends of the two fixing rods 14 can be slid into the mounting holes; in this structure, the pressing members 2, clamping blocks 12 and longitudinal frame 402 can be first installed on the threaded rod 11, then the fixing rods 14 at both ends of the longitudinal frame 402 are rotated to move towards each other and shorten the maximum length between the two fixing rods 14, until the longitudinal frame 402 and the fixing rods 14 can be put between the two vertical frames 403 on the left side or the right side of the rectangular frame 4, then the two fixing rods 14 are reversely rotated to move in opposite directions until they are inserted into the mounting holes, and the longitudinal frame 402 can be clamped between the two vertical frames 403 by continuously rotating the two fixing rods 14;

[0054] As shown, Figure 5 Since the pressing members 2, clamping blocks 12, partition plates 1 and threaded rods 11 of the present application can be collected between the longitudinal frames 402 without occupying other space outside the rectangular frame 4, the space utilization rate of the whole shelf is improved.

[0055] The working process of the present application is as follows: the staff first moves the four handles 15 on the two rotating rods 6 towards each other with both hands, so that the connecting rods 9 slide out of the supporting ears 8, and the rectangular frame 4 can be opened by rotating the two rotating rods 6 along the vertical axis; when the stored goods are high, the connecting rod 10 is slid to the left to drive the two connecting members 3 to slide out of the slide in the right layer plate, then the left layer plate and the right layer plate are rotated downward until the lower end surfaces of the two layer plates are clamped on the threaded rod 11 together with the connecting rod 10, and then the goods can be put in; finally, the pressing member 2 above the goods is rotated to press one end of the pressing member 2 against the goods to prevent the goods from moving up and down; at this time, the pressing member 2 vertically limits the goods, the threaded rods 11, clamping blocks 12 and partition plates 1 on the left and right sides of the rectangular frame 4 can limit the goods horizontally, and the stop members 5, rotating rods 6 and auxiliary limiting rods 7 at the front and rear ends of the rectangular frame 4 can limit the goods longitudinally, that is, the goods can be stably stored in the shelf; since the structure for realizing the above functions is simple, the manufacturing cost is low, the overall layout is reasonable, the space utilization rate is high, and it is suitable for promotion and use in warehouses.

[0056] Finally, it should be pointed out that the above examples are only used to illustrate the technical solutions of the present application and not to limit it, although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and they should be covered in the scope of the claims of the present application.
