Description

Technical Field

[0001] This utility model belongs to the field of storage device technology, specifically relating to a parallel lifting storage box. Background Technology

[0002] With the improvement of people's living standards and the abundance of material resources, how to efficiently and orderly store items has become a common problem in modern home life, office storage, and logistics transportation. Storage boxes, as a basic storage container, are widely used because they are easy to classify, stack, and move.

[0003] In existing technologies, in order to improve space utilization, storage boxes are built with multiple storage units (such as drawers). However, most drawers adopt an independent guide rail design, and users need to operate each drawer one by one in sequence to view all its contents. The operation process is cumbersome and the overall visibility is low. Especially when it is necessary to display and browse the items stored inside on a large scale, the lack of a linkage opening mechanism causes the drawers to not be able to open synchronously, thus failing to meet the usage needs. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a parallel lifting storage box to solve the technical problem that multiple storage units inside the storage box cannot be deployed synchronously in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A parallel lifting storage box includes a main body and storage components located on both sides of the main body that can be folded or unfolded. The main body and the storage components are connected by a parallel lifting assembly. The storage components include a first tray on the top of the main body, and a second tray and a third tray on each side of the first tray. The second tray and the third tray are rotatably connected to the main body by a parallelogram-shaped parallel lifting assembly. The parallel lifting assembly includes a main connecting rod rotatably connected to the first tray, and the two ends of the main connecting rod are rotatably connected to the second tray and the third tray, respectively. A first auxiliary connecting rod is also provided between the second tray and the main body, and the two ends of the first auxiliary connecting rod are rotatably connected to the second tray and the first tray, respectively. The first auxiliary connecting rod is located below the main connecting rod. A second auxiliary connecting rod is also provided between the third tray and the main body, and the two ends of the second auxiliary connecting rod are rotatably connected to the third tray and the first tray, respectively. The second auxiliary connecting rod is located above the main connecting rod. Furthermore, the parallel lifting assembly includes mounting slots on both sides of the first tray, a main connecting rod is provided in the mounting slot, and the middle part of the main connecting rod is rotatably connected to the center of the mounting slot. Furthermore, support components are provided on both sides of the second and third trays. The support components include a first support member that works in conjunction with the second tray, a second support member that works in conjunction with the third tray, and a locking limit member for locking and fixing. Furthermore, the first support member includes a first support rod disposed on both sides of the second tray. The first support rod is on the same side as the main connecting rod. The top of the first support rod is rotatably connected to the side of the second tray away from the first tray. The bottom of the first support rod is rotatably connected to the main body. Furthermore, a limiting link is provided on the side wall of the main body. The top end of the limiting link is rotatably connected to the main body, and the bottom end of the limiting link is rotatably connected to the bottom end of the first support rod. A limiting protrusion is provided on the side of the limiting link away from the first support rod. The limiting protrusion abuts against the limiting link, thereby limiting the rotation of the limiting link and the first support rod. Furthermore, an anti-sway link with an "L"-shaped cross section is provided on the side wall of the main body. One side of the anti-sway link is in contact with the main body, the top of the anti-sway link is rotatably connected to the main body, and the bottom of the anti-sway link is rotatably connected to the first support rod. A limiting block is provided on the inner side of the first support rod. When the first support rod rotates to be close to the main body, it abuts against the vertical component in the main body through the anti-sway link and the limiting block, thereby limiting the rotation of the first support rod. Furthermore, the second support member includes second support rods disposed on both sides of the third tray, the bottom end of the second support rods being rotatably connected to the main body, and a first horizontally extending crossbar being fixedly connected between the tops of the two second support rods; Furthermore, the locking and limiting component includes a first crossbar and a second crossbar located below the first crossbar. The two ends of the second crossbar are fixedly connected to the second support rods on both sides, and the axis of the second crossbar is parallel to the axis of the first crossbar. The locking and limiting component also includes locking hooks disposed on the side walls of the second tray and the third tray. Furthermore, an extension limiting component is provided between the second support rod and the main body to further limit the extension range of the second support rod; Furthermore, a three-way enclosure is provided under the first tray, with an opening on the side facing the third tray; a three-way enclosure is provided under the second tray, with an opening on the side facing the first tray; and an enclosure is provided between the second support rods on both sides, filling the space between the second support rods on both sides. After storage, the above enclosures completely cover the main body and storage components, forming a sealed storage space.

[0006] The beneficial effects of this utility model are as follows: Compared with existing technologies, by using a parallel lifting component to connect the main body and the storage component and setting up corresponding support components, it is possible to realize the synchronous unfolding and storage of multiple trays in the storage component in a short time, which is beneficial to the display of all contents. In addition, the operation is simple and can be completed by a single person, effectively improving work efficiency. Attached Figure Description

Detailed Implementation

[0009] Example 1, specifically as follows Figures 1-12 As shown.

[0010] A parallel lifting storage box includes a main body 1 in the shape of a cuboid frame and storage components 2 located on both sides of the main body 1 that can be stored or unfolded. The main body 1 and the storage components 2 are connected by a parallel lifting component 3.

[0011] like Figure 1 As shown, the storage component 2 includes a first tray 201 disposed on the top of the main body 1. In this embodiment, a groove is provided on the upper surface of the top plate of the main body 1, and the groove is surrounded by sidewalls. The groove has a rectangular cross-section and extends vertically to form the first tray 201.

[0012] The first tray 201 is provided with a second tray 202 and a third tray 203 on both sides, such as Figure 1 , Figure 2 As shown, both the second tray 202 and the third tray 203 are rectangular plates with openings at the top. It is worth emphasizing that the second tray 202 and the third tray 203 are rotatably connected to the main body 1 through a parallel lifting component 3 with a parallelogram structure. When the storage component 2 is stored, the second tray 202 and the third tray 203 are located on the vertical sides of the first tray 201, respectively. When the storage component 2 is unfolded, the second tray 202 and the third tray 203 are located on the horizontal sides of the first tray 201, respectively.

[0013] like Figure 3 , Figure 4As shown, the parallel lifting assembly 3 includes mounting grooves 301 formed on the side walls of the first tray 201. The mounting grooves 301 extend vertically, and connecting blocks are reserved on both sides of the mounting grooves 301. The solid parts on both sides of the mounting grooves 301 are connected together by the connecting blocks to prevent the side walls of the first tray 201 from being completely separated into two independent parts by the mounting grooves 301.

[0014] A main connecting rod 302 is provided within the mounting groove 301. The middle part of the main connecting rod 302 is rotatably connected to the center position of the mounting groove 301. In this embodiment, a rotating shaft is fixedly connected to the center position of the mounting groove 301, and the extension direction of the rotating shaft is perpendicular to the width direction of the mounting groove 301. The main connecting rod 302 is sleeved on the rotating shaft. It is necessary to further explain that the length of the main connecting rod 302 is greater than the length of the side wall of the first tray 201 of the mounting groove, that is, when the main connecting rod 302 is in a horizontal state, both ends of the main connecting rod 302 are exposed in the mounting groove 301.

[0015] The two ends of the main connecting rod 302 are rotatably connected to the second tray 202 and the third tray 203, respectively. Specifically, the ends of the second tray 202 and the third tray 203 near the first tray 201 are connected to the ends of the main connecting rod 302 through a pivot. The pivot connection point is located in the middle of the height direction of the outer side wall of the second tray 202 and the third tray 203.

[0016] A first auxiliary connecting rod 303 is also provided between the second tray 202 and the main body 1. The two ends of the first auxiliary connecting rod 303 are rotatably connected to the second tray 202 and the mounting groove 301, respectively. Through the main connecting rod 302 and the first auxiliary connecting rod 303, a parallelogram linkage mechanism is formed between the second tray 202 and the main body 1. Specifically, the first auxiliary connecting rod 303 is located below the main connecting rod 302. The inner end of the first auxiliary connecting rod 303 is rotatably connected to the end of the mounting groove 301 near the second tray 202 via a pivot. The outer end of the first auxiliary connecting rod 303 is rotatably connected to the middle part of the outer wall of the second tray 202 in the horizontal direction via a pivot.

[0017] A second auxiliary connecting rod 304 is also provided between the third tray 203 and the main body 1. The two ends of the second auxiliary connecting rod 304 are rotatably connected to the third tray 203 and the mounting groove 301, respectively. Through the main connecting rod 302 and the second auxiliary connecting rod 304, a parallelogram linkage mechanism is formed between the third tray 203 and the main body 1. Specifically, the second auxiliary connecting rod 304 is located above the main connecting rod 302. The inner end of the second auxiliary connecting rod 304 is rotatably connected to the end of the mounting groove 301 near the third tray 203 via a pivot. The outer end of the second auxiliary connecting rod 304 is rotatably connected to the middle part of the outer wall of the third tray 203 in the horizontal direction via a pivot.

[0018] In other embodiments besides this one, the main connecting rod 302, the first auxiliary connecting rod 303, and the second auxiliary connecting rod 304 are all rotatably connected to the outer wall of the side wall of the first tray 201, and their positional relationship is the same as in this embodiment, so there is no need to open the mounting slot 301 again.

[0019] During use, due to the different load-bearing capacities of the second tray 202 and the third tray 203, regardless of whether the storage component 2 is in the unfolded or retracted state, the second tray 202 and the third tray 203 will be unable to maintain balance and will shake, affecting the performance.

[0020] Therefore, support components 4 are also provided on both sides of the second tray 202 and the third tray 203. The support components 4 include a first support member 41 that works in conjunction with the second tray 202, a second support member 42 that works in conjunction with the third tray 203, and a locking and limiting member 43 for locking and fixing.

[0021] like Figure 2 As shown, the first support member 41 includes first support rods 411 disposed on both sides of the second tray 202. The first support rods 411 are on the same side as the main connecting rod 302. The top of the first support rods 411 is rotatably connected to the side of the second tray 202 away from the first tray 201. The bottom of the first support rods 411 is rotatably connected to the main body 1. When the second tray 202 is fully unfolded and fully retracted, the first support rods 411 cannot rotate further and provide support for the second tray 202. Specifically, a limiting connecting rod 412 is provided on the side wall of the main body 1. The top of the limiting connecting rod 412 is rotatably connected to the main body 1, and the bottom of the limiting connecting rod 412 is rotatably connected to the bottom of the first support rod 411. A limiting protrusion 413 is provided on the side of the limiting connecting rod 412 away from the first support rod 411. The limiting protrusion 413 abuts against the limiting connecting rod 412, thereby limiting the rotation of the limiting connecting rod 412 and the first support rod 411.

[0022] The second support member 42 includes second support rods 421 disposed on both sides of the third tray 203, the bottom end of the second support rods 421 being rotatably connected to the main body 1. A first crossbar 422 extending horizontally is fixedly connected between the tops of the two second support rods 421.

[0023] The locking and limiting component 43 includes a first crossbar 422 and a second crossbar 432 located below the first crossbar 422. Similarly, both ends of the second crossbar 432 are fixedly connected to the second support rods 421 on both sides, and the axis of the second crossbar 432 is parallel to the axis of the first crossbar 422. The locking and limiting component 43 also includes locking hooks 431 that are rotatably connected to the side walls of the second tray 202 and the third tray 203. Taking the second tray 202 as an example, the locking hooks 431 are distributed on both sides of the second tray 202 and the locking hooks 431 are located at the end of the second tray 202 away from the first support rod 411. The two locking hooks 431 are connected by a connecting rod to form a whole.

[0024] In embodiments other than this one, the locking hook 431 is slidably connected to the side walls of the second tray 202 and the third tray 203, specifically, as shown in the example below. Figure 11 , Figure 12 As shown, taking the second tray 202 as an example, locking hooks 431 are distributed on both sides of the second tray 202, and the locking hooks 431 are located at the end of the second tray 202 away from the first support rod 411. The two locking hooks 431 are connected by a connecting rod to form a whole. Two limiting protrusions are provided opposite each other on the side wall of the second tray 202, and a vertical limiting groove 434 is formed between the limiting protrusions. The top of the locking hook 431 is located in the limiting groove 434 and is slidably connected to the limiting groove 434.

[0025] When unfolded, the locking hook 431 on the third tray 203 engages with the first crossbar 422 on the second support rod 421, thereby restricting the rotation of the second support rod 421. At the same time, the first crossbar 422 abuts against the bottom of the third tray 203, providing support for the third tray 203 and maintaining its stability.

[0026] To further limit the extension range of the second support rod 421, an extension limiting member is provided between the second support rod 421 and the main body 1. In this embodiment, the extension limiting member is a chain 423. The two ends of the chain 423 are fixedly connected to the main body 1 and the second support rod 421, respectively. When the chain 423 is fully straightened, the second support rod 421 reaches its maximum extension range.

[0027] When the tray is closed for storage, the locking hook 431 on the second tray 202 engages with the first crossbar 422, and the first crossbar 422 abuts against the bottom of the second tray 202, thereby locking and supporting the second tray 202; the bottom of the third tray 203 abuts against the second crossbar 432, forming a locking and supporting function, and also preventing the end of the third tray 203 from vibrating; in addition, the second crossbar 432 abuts against the main body, thereby restricting the further rotation of the second support rod 421.

[0028] Taking the second tray 202 as an example again, in order to further improve the stability of the locking hook 431 when it is engaged, the connecting rod between the two locking hooks 431 and the second tray 202 is elastically connected by a spring 433. Specifically, the spring 433 is located on the side of the second tray 202 away from the first support rod 411. The spring 433 extends vertically, and its top end is fixedly connected to the connecting rod between the two locking hooks 431, while its bottom end is fixedly connected to the pivot on the second tray 202. The spring 433 applies preload to the locking hook 431 through its rebound, preventing it from disengaging.

[0029] A horizontal handle 44 is fixedly connected between the top ends of the first support rods 411 on both sides. Similarly, a handle 44 is also fixedly connected between the top ends of the second support rods 421 on both sides. The handles 44 facilitate the application of force to the support assembly 4. By using a parallel lifting component 3 to connect the main body 1 and the storage component 2, and setting up corresponding support components 4, multiple trays in the storage component 2 can be simultaneously unfolded and stored in a short time, which is beneficial for displaying all the contents. In addition, the operation is simple and can be completed by a single person, effectively improving work efficiency. Example

[0030] like Figure 13 As shown, locking holes 424 are provided on the top of the second support rod 421 and the side wall of the third tray 203 respectively. In the display state, the pin 425 is inserted into the locking hole 424, thereby connecting the second support rod 421 and the third tray 203 to achieve a fixing effect. Example

[0031] like Figure 14 , 15 As shown, the top of the limiting link 412 is rotatably connected to the main body 1 via a pivot, and the bottom of the first support rod 411 is rotatably connected to the bottom of the limiting link 412 via a pivot. In this embodiment, the pivot protrudes from the outer surface of the limiting link 412. When the first support rod 411 rotates to be close to the main body 1, the first support rod 411 abuts against the pivot, thereby limiting the rotation of the first support rod 411. Example

[0032] like Figure 16 As shown, an L-shaped anti-sway link 414 is provided on the side wall of the main body 1. One side of the anti-sway link 414 is in contact with the main body 1, the top end of the anti-sway link 414 is rotatably connected to the main body 1, and the bottom end of the anti-sway link 414 is rotatably connected to the first support rod 411. A limit block 415 is welded to the inner side of the first support rod 411. When the first support rod 411 rotates close to the main body 1, it abuts against the vertical components in the main body 1 through the anti-sway link 414 and the limit block 415, thereby limiting the rotation of the first support rod 411. Example

[0033] As Figure 16 shown, the unfolding limiting member adopts a two-link 427, and both ends of the two-link 427 are rotatably connected to the second support rod 421 and the main body 1 respectively. During the unfolding process, the two-link 427 unfolds synchronously with the rotation of the second support rod 421. When the second support rod 421 rotates to a predetermined angle, the two-link 427 reaches the maximum unfolding angle, thereby limiting further rotation of the second support rod 421 and achieving the limiting effect. Example

[0034] As Figure 17 shown, the unfolding limiting member adopts a limiting plate 426, both ends of the limiting plate 426 are fixedly connected to the bottoms of the second support rods 421 on both sides, the limiting plate 426 is located on the back surface of the side of the second support rods 421 away from the main body, and the two are fixedly connected by welding. During the unfolding process, the second support rod 421 rotates in a direction away from the main body 1. When rotated to a predetermined angle, the bottom of the limiting plate 426 abuts against the main body 1, thereby playing a limiting role, preventing further rotation of the second support rod 421, so that the second support rod 421 remains stable. Example

[0035] As Figure 18 shown, a three-way enclosure 5 is provided below the first tray 201, and the side thereof facing the third tray 203 is open; a three-way enclosure 5 is provided below the second tray 201, and the side thereof facing the first tray 201 is open, and an enclosure 5 is provided between the two second support rods 421, which fills the space between the two second support rods 421. After storage is completed, the above enclosure 5 completely wraps the main body 1 and the storage assembly 2, forming a sealed storage space. Example

[0036] As Figure 18 shown, universal wheels 6 are additionally installed at the bottom of the main body 1, which improves the flexibility and use convenience of the entire storage box. Example

[0037] As Figure 18 shown, a flexible strap 7 is fixedly connected to one side of the main body 1. When manual carrying up and down stairs or similar carrying requirements are needed, carrying can be realized through the flexible strap. Moreover, the flexible strap can disperse the load relatively uniformly to the carrier's whole body, which is beneficial to protecting the safety of the carrier. Example

[0038] As Figure 18 shown, the outer ends of the second tray 202 and the third tray 203 are both rotatably connected with a handle 8, the handle 8 is in a "匚"-shaped frame structure, and the handle 8 facilitates carrying the entire storage box. Example

[0039] As Figure 18 shown, supporting legs 9 are rotatably connected to both sides of the bottom of the main body 1, and the supporting legs 9 also have a "匚"-shaped frame structure. When high-position display is required, the height-increasing effect can be achieved through the supporting legs 9. Example

[0040] As Figure 18 shown, inclined telescopic rods 10 are fixedly connected to the bottom of the main body 1 and the outer ends of the trays on both sides. The entire storage box is pushed to move through the telescopic rods 10, and the top ends of the telescopic rods 10 on the same side are fixedly connected through a cross bar, thereby facilitating force application and controlling the moving direction.

[0041] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the present utility model without limitation. Although the present utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present utility model.
