A stacked propulsion device

Abstract

This utility model relates to the field of item propulsion technology, and discloses a stacked propulsion device, including multiple sets of storage boxes for item retrieval and placement, which together constitute a storage unit. Each storage box has a detachably connected fixed baffle and a movable baffle at both ends. Each storage box contains a propulsion component for item propulsion, and the propulsion component is slidably connected to the storage box. By setting up the propulsion component, when an item at the front is removed, the elastic restoring force of the coil spring within the propulsion component drives a push plate within the propulsion component to slide along the inside of the storage box, automatically moving subsequent items forward to fill the gap. This design ensures that items always remain aligned with the retrieval opening, effectively avoiding the problem of subsequent items becoming unbalanced and tipping over due to missing items at the front in previous stacked structures, thus improving the ease of retrieval.

Description

Technical Field

[0001] This utility model relates to the field of article propulsion technology, and in particular to a propulsion device with a stacked structure. Background Technology

[0002] In daily life and business activities, the need for storing and retrieving items such as candy boxes, cosmetics, and e-cigarettes is extremely common. Taking candy box sales scenarios as an example, whether it is the candy boxes displayed on supermarket shelves or the various candy boxes displayed on the carefully designed display shelves in candy specialty stores, these scenarios mostly use long and narrow storage boxes to organize the candy boxes in an orderly manner.

[0003] Currently, most common storage boxes on the market feature an open top and a surrounding bottom design. This design provides stable support for items placed inside (such as candy boxes, cosmetics, e-cigarettes, etc.), allowing items to be stacked neatly inside the box. The open top also makes it easy for staff to retrieve items or restock. However, because the items in these existing storage boxes are stacked one on top of the other, when an item in front is removed and not replaced promptly, the items behind it can easily become unbalanced and tip over to the bottom of the box. This makes it very inconvenient for staff to retrieve items later, requiring them to carefully lift the items from the bottom of the box, significantly impacting the ease of access.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a propulsion device with a stacked structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stacked propulsion device includes multiple sets of storage boxes for picking up and placing items, the multiple sets of storage boxes constituting a storage unit;

[0008] The storage box has a fixed baffle and a movable baffle that can be detachably connected at both ends; the storage box has a propulsion component for pushing items in, and the propulsion component is slidably connected to the storage box.

[0009] As further explained, the storage box includes a base and two sets of side panels; the bottom surface of the base is provided with a first slot at each end; the two sets of side panels are symmetrically arranged on both sides of the base, and the base and the two sets of side panels are integrally formed; the top of the side panel is provided with a first locking block corresponding to the first slot.

[0010] As further explained, the side plate is provided with a connecting plate; the bottom end of the connecting plate is provided with a second slot that engages with the first slot, and the top end of the connecting plate is provided with a second slot that engages with the first slot.

[0011] As further explained, multiple sets of storage boxes are distributed circumferentially around one set of storage boxes as the center, and adjacent sets of storage boxes are connected end to end by the connecting plate to form a honeycomb structure storage unit.

[0012] As further explained, the multiple sets of storage boxes are arranged in a matrix, with adjacent sets of storage boxes connected by connecting plates and adjacent sets of storage boxes connected by fasteners to form parallel vertically arranged storage units.

[0013] As further explained, the propulsion assembly includes a coil spring and a push plate; the push plate is disposed inside the storage box, and the storage box is provided with a sliding groove for the push plate to slide; the coil spring is disposed on one side of the push plate, and a fixing cavity is provided between the coil spring and the push plate; one end of the coil spring passes through the bottom end of the push plate and extends to the bottom end of the movable baffle, and engages with the movable baffle.

[0014] As further explained, the coil spring is provided with a first snap-fit ​​hole at one end near the movable baffle; the bottom end of the movable baffle is provided with a first snap-fit ​​post that protrudes downward, and the first snap-fit ​​post is provided with a first guide slope on the side near the push plate, and the first snap-fit ​​hole is engaged with the first snap-fit ​​post.

[0015] As a further explanation, the bottom end of the movable baffle is provided with a insertion groove for the coil spring to pass through; the insertion groove is provided with a limiting block for limiting the position, and the limiting block is located above the coil spring.

[0017] As a further explanation, the base plate is provided with a limiting groove corresponding to the movable plate; the bottom end of the movable plate is provided with a limiting part extending into the limiting groove; when the movable plate and the base plate are tilted, one side of the limiting part abuts against the limiting groove, and the limiting groove limits and supports the movable plate.

[0018] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0019] 1. By setting up a push component, when the item at the front is taken out, the elastic restoring force of the coil spring in the push component drives the push plate in the push component to slide along the inside of the storage box, automatically filling the position of the item behind.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] In one embodiment of this utility model, such as Figure 1-6 As shown, a stacked propulsion device is provided, including multiple sets of storage boxes 10 for picking up and putting down items, and the multiple sets of storage boxes 10 constitute a storage unit.

[0038] The storage box 10 has a fixed baffle 21 and a movable baffle 22 that can be detachably connected at both ends. The storage box 10 has a propulsion component 30 for pushing items, and the propulsion component 30 is slidably connected to the storage box 10.

[0039] By setting up the push assembly 30, when the item at the front is taken out, the elastic restoring force of the coil spring 31 in the push assembly 30 drives the push plate 32 in the push assembly 30 to slide along the inside of the storage box 10, automatically filling the position of the item behind. This design ensures that the item always maintains a stable state aligned with the pick-up and drop-off port, effectively avoiding the problem of the item behind becoming unbalanced and falling over due to the lack of the item at the front in the previous stacking structure, and improving the convenience of picking up and dropping.

[0040] By setting up a movable baffle 22, the movable plate 226 inside the movable baffle 22 can be angled around the base plate 225 inside the movable baffle 22. During the process of picking up items, the movable plate 226 can be flexibly tilted and adapted according to the operational requirements, so as to make it easier to pick up items and further improve the convenience of picking up items.

[0041] Preferably, the storage box 10 includes a base 11 and two sets of side panels 12. The bottom surface of the base 11 has first slots 111 at both ends. The two sets of side panels 12 are symmetrically arranged on both sides of the base 11, and the base 11 and the two sets of side panels 12 are integrally formed. The top of the side panel 12 has a first locking block 121 corresponding to the first slot 111. The integrally formed structure of the base 11 and side panels 12 enhances the rigidity of the storage box 10, preventing deformation. Furthermore, the first slots 111 and first locking blocks 121 allow adjacent sets of storage boxes 10 to be connected by the first slot 111 of one set and the first locking block 121 of the other set, creating storage units that can be freely combined according to actual needs. This improves the versatility of the storage box 10 in different situations, adapting to various scenarios.

[0042] Furthermore, a connecting plate 13 is provided on the side panel 12. The bottom end of the connecting plate 13 is provided with a second slot 131 that engages with the first slot 121, and the top end of the connecting plate 13 is provided with a second slot 132 that engages with the first slot 111. By providing the connecting plate 13, the parts that cannot be connected between two adjacent sets of storage boxes 10 can be connected by the connecting plate 13 to form a complete structure, thereby improving the stability and practicality of the storage unit after arbitrary combination, and preventing items inside the storage box 10 from falling out randomly.

[0043] Furthermore, multiple sets of storage boxes 10 are distributed circumferentially around one set of storage boxes 10 as the center, and adjacent sets of storage boxes 10 are connected end to end by connecting plates 13 to form a honeycomb structure storage unit. The honeycomb structure formed by the interlocking of the connecting plates 13 allows adjacent storage boxes 10 to support each other, reducing the impact of external vibrations on the arrangement of items inside individual boxes, preventing chain collapse, and further improving the overall structural stability of the storage unit.

[0044] Furthermore, multiple sets of storage boxes 10 are arranged in a matrix. Two adjacent sets of storage boxes 10 are connected by a connecting plate 13, and two adjacent sets of storage boxes 10 are connected by fasteners 16, forming a vertically arranged storage unit. In this embodiment, the fasteners 16 are long, fixed rails. Two sets of fasteners 16 are arranged side-by-side at the bottom of two adjacent sets of storage boxes 10, and the bottom of each storage box 10 has a corresponding locking rail, ensuring that the two adjacent sets of storage boxes 10 can be placed stably. The fixed connections at the top, bottom, left, and right ensure the stability of the storage boxes 10, preventing local displacement from causing the pushing component 30 to jam or items to shift, maintaining an aligned state for easy retrieval by the user.

[0045] Preferably, the pushing assembly 30 includes a coil spring 31 and a push plate 32. The push plate 32 is disposed inside the storage box 10, and the storage box 10 has a sliding groove 14 for the push plate 32 to slide. The coil spring 31 is disposed on one side of the push plate 32, and a fixing cavity is provided between the coil spring 31 and the push plate 32. One end of the coil spring 31 passes through the bottom end of the push plate 32 and extends to the bottom end of the movable baffle 22, and engages with the movable baffle 22. By setting the coil spring 31 and the push plate 32, the elastic restoring force of the coil spring 31 drives the push plate 32 to slide along the inside of the storage box 10, automatically filling the gap for items behind. This design ensures that items always maintain a stable state aligned with the retrieval opening, effectively avoiding the problem of items behind becoming unbalanced and falling over due to the absence of items at the front in previous stacking structures, and improving the convenience of retrieval.

[0046] Furthermore, the coil spring 31 has a first engaging hole 311 at the end near the movable baffle 22. The bottom end of the movable baffle 22 has a downwardly protruding first engaging post 221, and the first engaging post 221 has a first guide slope 222 on the side near the push plate 32. The first engaging hole 311 engages with the first engaging post 221. By setting the first engaging post 221 and the first engaging hole 311, the connection stability between the coil spring 31 and the movable baffle 22 is enhanced, preventing the coil spring 31 from easily detaching from the movable baffle 22 and causing pushing failure, thus ensuring the normal use of the pushing assembly. At the same time, by setting the first guide slope 222, the coil spring 31 can be more easily engaged in the first engaging post 221 under the guidance of the first guide slope 222, simplifying the installation steps between the two.

[0047] Furthermore, the bottom of the movable baffle 22 is provided with an insertion groove 223 for the coil spring 31 to pass through. A limiting block 224 for positioning is provided within the insertion groove 223, and the limiting block 224 is located above the coil spring 31. By setting the limiting block 224, the position of the coil spring 31 is constrained, preventing lateral displacement that could cause the push plate 32 to slide and jam, thus ensuring smooth forward movement of the item.

[0048] Preferably, the movable baffle 22 includes a base plate 225 and a movable plate 226. The base plate 225 is located on one side of the storage box 10, and has a downwardly protruding second locking post 225a. The second locking post 225a has a second guide slope 225b on the side near the push assembly 30. The storage box 10 has a second locking hole 15 that engages with the second locking post 225a. The movable plate 226 is vertically mounted on the base plate 225, and a pin is provided between the movable plate 226 and the base plate 225. By setting the base plate 225 and the movable plate 226, the movable plate 226 can be angled around the base plate 225. During the process of retrieving items, the movable plate 226 can flexibly tilt and adapt according to the operational needs, so as to facilitate the retrieval of items and further improve the convenience of retrieval.

[0049] Furthermore, the base plate 225 is provided with a limiting groove 225c corresponding to the movable plate 226. The bottom end of the movable plate 226 is provided with a limiting part 226a extending into the limiting groove 225c. When the movable plate 226 is tilted relative to the base plate 225, one side of the limiting part 226a abuts against the limiting groove 225c, and the limiting groove 225c limits and supports the movable plate 226. The movable plate 226 achieves controllable tilting through the limiting groove 225c and the limiting part 226a, providing support during handling and preventing items from slipping due to excessive backward tilting.

[0050] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
