Description

Technical Field

[0001] This application relates to the field of storage devices, and in particular to storage devices with bidirectional access. Background Technology

[0002] Warehouses or storage areas for electronic components are typically equipped with shelves and other devices for storing parts. To facilitate access, these devices are usually arranged in a compartmentalized manner, allowing for quick retrieval and efficient handover of items at different times.

[0003] Related technology can be found in Chinese Patent Publication No. CN105947518A, which discloses an automated vending machine. This automated vending machine includes a cabinet, a transmission cabinet, a storage cabinet, a barcode scanner, a barcode printer, a controller, and a transmission belt. The cabinet has a transmission cabinet and a storage cabinet, which are connected. The transmission cabinet has a storage compartment door, a barcode scanner, a barcode printer, and a controller. A transmission chain is vertically mounted inside the transmission cabinet via a support bearing. A storage box is mounted on the transmission chain. The storage box is open on the side where the transmission cabinet and the storage cabinet are connected, and it is also open on the side where the storage compartment door is located. A first push plate is located inside the storage box and is positioned on one side of the storage cabinet. The first push plate is driven by a first push rod.

[0004] Regarding the aforementioned technologies, due to the storage needs of warehouses, the space layout inside warehouses is generally quite compact, and the walking and transportation channels are relatively narrow. Storage compartment doors are generally installed using a hinged method. When the storage compartment door is open, it protrudes and occupies space outside the device, which affects the movement of people in front of the device and is also prone to accidental collisions and dangers. Even if the storage compartment door is rotated 180°, it will affect the opening of adjacent storage compartments, making it inconvenient to use. Summary of the Invention

[0005] To improve ease of use, this application provides a storage device with bidirectional access.

[0006] This application provides a two-way access storage device, which adopts the following technical solution: A bidirectional storage device includes a frame with several storage slots that are connected front to back. Several opening doors for opening and closing the openings of the storage slots are movably connected to the frame. A connecting shaft is fixed to one side of each opening door, and a locking element is provided on the other side. The connecting shaft is rotatably connected to the frame. The frame has several clearance slots that are adapted to and correspond one-to-one with the opening doors. The clearance slots are located on the side of the storage slots closest to the connecting shaft. The frame has a transmission structure for controlling the movement of the opening doors into the clearance slots. The transmission structure includes a connection to the end of the connecting shaft. The storage compartment has a matching sliding groove that connects to the clearance groove. Both the clearance groove and the sliding groove are set along the length of the storage compartment. When the door is closed, the end of the connecting shaft is embedded in the sliding groove near the opening of the storage compartment. The sliding grooves at both ends of the storage compartment are connected by a connecting hole. A crossbar is slidably connected in the connecting hole. Both ends of the crossbar are integrally formed with a locking part. The connecting shaft is provided with a slot that matches the locking part. When the door at one end of the storage compartment moves into the clearance groove, it pushes the crossbar so that the locking part at the other end is embedded into the slot of the corresponding connecting shaft.

[0007] By adopting the above technical solution, when the user opens the door, the door is controlled to rotate around the connecting shaft to open. After opening, the door faces the clearance groove. At this time, the user uses the transmission structure to control the door to move into the clearance groove, so that the door is fully embedded in the clearance groove. At this time, the door will not occupy the space in front of the frame, nor will it affect the opening of adjacent doors, and the opening process will not occupy the space in the storage compartment. The end of the connecting shaft is embedded in the sliding groove. When the door is not facing the clearance groove, the connecting shaft rotates in place as the door rotates. When the door is facing the clearance groove, the connecting shaft rotates in place. When the door is in the clearance slot, the user controls the door to move into the clearance slot. At this time, the connecting shaft slides along the slide to the other end of the clearance slot, thus realizing the movement of the door into the clearance slot. The structure is simple and easy to control. After the door at one end of the storage slot is opened and enters the clearance slot, the locking part at the other end of the crossbar is pushed into the slot of the connecting shaft of the other door, thereby restricting the rotation of the other door and realizing self-locking. It is not easy for the doors at both ends of the same storage slot to open at the same time, ensuring less communication and contact between the two parties exchanging items, improving convenience while providing good protection.

[0008] Optionally, the crossbar is a telescopic bar, the slot of the slot is provided with a flared part, and a first elastic element is connected between the two ends of the crossbar. In the natural state of the first elastic element, the crossbar is in an extended state, and the locking parts are all located in the corresponding flared parts.

[0009] By adopting the above technical solution, when the user opens one side of the door, the corresponding connecting shaft rotates, the corresponding locking part abuts against the side wall of the flared part, and the crossbar gradually slides to the other end until the locking part on the side of the opened door disengages from the corresponding flared part. At this time, the locking part on the other end is embedded in the corresponding slot. Even if the door is not fully opened to align with the clearance slot, the other side of the door can still be locked. It is not easy for the other side of the door to be opened while the user is rotating the door. Furthermore, when the door moves into the clearance slot, the first elastic element can be shortened without affecting the movement of the door into the clearance slot. The structure is simple and does not require any additional operation from the user.

[0010] Optionally, each of the slots is provided with a second elastic element. The extension and retraction direction of the second elastic element is the same as the sliding direction of the crossbar. In its natural state, the locking part of the second elastic element is located outside the slot.

[0011] By adopting the above technical solution, the second elastic element can ensure that when both sides of the opening and closing doors are closed, the locking parts at both ends of the crossbar will not accidentally lock either opening and closing door, ensuring that the opening and closing door on either side can be opened smoothly when both sides of the opening and closing doors are closed. The structure is simple and the effect is good.

[0012] Optionally, a third elastic element is connected between the connecting shaft and the wall of the clearance groove. In its natural state, the entire opening and closing door is located within the clearance groove.

[0013] By adopting the above technical solution, when the user opens the door until it aligns with the clearance groove, the door automatically retracts into the clearance groove after overcoming the elastic force of the first elastic element under the elastic pull of the third elastic element. This eliminates the need for the user to manually control the door to move into the clearance groove, further improving operational convenience.

[0014] Optionally, the transmission structure includes an annular elastic rope, which is movably connected between two opening and closing doors on both sides of the same storage tank. The annular elastic rope includes a first connecting section arranged along the length direction of the opening and closing doors and a second connecting section arranged along the width direction of the frame. When both opening and closing doors on both sides of the same storage tank are closed, the annular elastic rope is in its natural state.

[0015] By adopting the above technical solution, when one of the opening and closing doors is opened, the annular elastic rope is stretched. When the opened opening and closing door aligns with the clearance groove, the elastic restoring force of the annular elastic rope causes the opening and closing door to automatically move into the clearance groove, eliminating the need for manual control by the user, thus improving operational convenience. At the same time, since the annular elastic rope is always in a natural state when closed, it is less prone to fatigue and has a longer service life. Furthermore, if the user does not fully open the opening and closing door to align with the clearance groove, the annular elastic rope will automatically close the door, further reducing the space occupied by the opening and closing door outside the frame and improving ease of use.

[0016] Optionally, the opening and closing door is provided with a first handle at the end away from the connecting shaft. The first handle is located on the side of the opening and closing door near the storage slot, and a through slot adapted to the first handle is connected between the clearance slot and the storage slot.

[0017] By adopting the above technical solution, users can use the first handle to pull the door out of the clearance groove for closing. The structure is simple and the user is very convenient.

[0018] In summary, this application includes at least one of the following beneficial technical effects: 1. When the user opens the door, the door is controlled to rotate around the connecting shaft to open. After opening, the door faces the clearance groove. At this time, the user uses the transmission structure to control the door to move into the clearance groove so that the door is fully embedded in the clearance groove. At this time, the door will not occupy the space in front of the frame, nor will it affect the opening of adjacent doors. Moreover, the opening process will not occupy the space in the storage compartment, making it highly convenient to use. 2. When the user opens one side of the door, the corresponding connecting shaft rotates, the corresponding locking part abuts against the side wall of the flared part, and the crossbar gradually slides to the other end until the locking part on the side of the opened door disengages from the corresponding flared part. At this time, the locking part on the other end is inserted into the corresponding slot. Even if the door is not fully opened to align with the clearance slot, the other side of the door can still be locked. It is not easy for the other side of the door to be opened while the user is rotating the door. Furthermore, when the door moves into the clearance slot, the first elastic element can be shortened without affecting the movement of the door into the clearance slot. The structure is simple and does not require any additional operation from the user. 3. When one of the opening doors is opened, the ring-shaped elastic rope is stretched. When the opened door aligns with the clearance groove, the elastic restoring force of the ring-shaped elastic rope causes the door to automatically move into the clearance groove without the need for manual control by the user, thus improving ease of operation. At the same time, since the ring-shaped elastic rope is always in a natural state when closed, it is less prone to fatigue and has a longer service life. Furthermore, if the user does not fully open the door to align with the clearance groove, the ring-shaped elastic rope will automatically close the door, further reducing the space occupied by the door outside the frame and improving ease of use.

[0026] The present application will be further described in detail below with reference to all the accompanying drawings.

[0027] This application discloses a bidirectional storage device.

[0028] Example 1: Reference Figure 1 The storage device with two-way access includes a frame 1, which is rectangular in shape. The frame 1 has several storage slots 11 arranged along its width direction. All storage slots 11 are square slots. Both sides of the frame 1 in the width direction are connected to the storage slots 11. Both sides of the frame 1 in the width direction are equipped with opening and closing doors 2 for closing the openings of the storage slots 11. In use, one side is used for storing items and the other side is used for retrieving items, thereby realizing the transfer of items without the need for contact between the two parties.

[0029] Reference Figure 1 The storage slots 11 are evenly distributed on the frame 1, and the different storage slots 11 are not interconnected, allowing for independent storage and retrieval of items. Under normal conditions, the opening and closing doors 2 at both ends of the storage slots 11 are in the closed state. A locking device 24 is installed between the opening and closing door 2 and the frame 1. The locking device 24 can be an electronic lock or a mechanical lock, which can lock the opening and closing door 2 when it is closed.

[0030] Reference Figure 1 Both ends of the storage compartment 11 are connected to flared slots 14 that are adapted to the opening and closing door 2. When the opening and closing door 2 is closed, it is embedded in the flared slot 14. Its outer side is in the same vertical plane as the side of the frame 1, so it does not occupy the space outside the frame 1. Personnel are less likely to accidentally bump into the corners or other parts of the opening and closing door 2 and cause danger. When it is necessary to store or retrieve items, the user opens the locking piece 24 on the side of a storage compartment 11 from one side.

[0031] Reference Figure 1 and Figure 2 The locking element 24 is located at one end of the opening and closing door 2 along its length. A connecting shaft 21 is fixedly installed at the end of the opening and closing door 2 away from the locking element 24. The connecting shaft 21 is a vertically arranged round shaft. The frame 1 is provided with a transmission structure, which includes several slide grooves 13 opened on the frame 1. The slide grooves 13 are strip-shaped grooves arranged along the length of the storage groove 11. The width of the slide grooves 13 is adapted to the diameter of the connecting shaft 21. One connecting shaft 21 corresponds to two slide grooves 13. The end of the connecting shaft 21 is embedded in the slide groove 13. The two slide grooves 13 limit the connecting shaft 21 from the upper and lower ends, so that the connecting shaft 21 can only move along the length of the slide groove 13.

[0032] Reference Figure 1 and Figure 2 When the door 2 is closed, the connecting shaft 21 is located at the end of the corresponding slide 13 near the edge of the frame 1. At this time, the length direction of the door 2 is perpendicular to the length direction of the slide 13. Due to the obstruction of the frame 1, the connecting shaft 21 cannot move along the length direction of the slide 13 under the action of the door 2.

[0033] A second handle 23 is installed on the outer side of the door 2 near the electronic lock. In this embodiment, the second handle 23 is an embedded handle, which, compared to a regular handle, is less likely to protrude and occupy space outside the frame 1, and is less likely to cause accidental collisions with the handle, making it safer and more convenient to use. When the user pulls the second handle 23 to pull the door 2 outward, the door 2 and the connecting shaft 21 will rotate synchronously along the axis of the connecting shaft 21, thereby opening the storage compartment 11, making it easy for the user to store and retrieve items into the storage compartment 11.

[0034] Reference Figure 1 and Figure 2 In situations where it is inconvenient for both parties to make contact, if one party opens the door 2, the other party cannot open the door 2 at the other end of the same storage compartment 11. In this embodiment, a self-locking mechanism 3 is provided between the doors 2 at both ends of the two storage compartments 11, so that after one party opens the door 2, the other party cannot open the corresponding door 2 even if the locking member 24 is opened.

[0035] Reference Figure 1 and Figure 2The connecting shafts 21 at both ends of the same storage slot 11 are located on the same side of the storage slot 11, so the slide 13 is also located on the same side of the storage slot 11. The self-locking mechanism 3 includes a crossbar 31. The slide 13 at both ends of the same storage slot 11, which are located on the same straight line, are connected by a connecting hole 16. The crossbar 31 is movably inserted into the connecting hole 16. The crossbar 31 is a telescopic rod, that is, the crossbar 31 is composed of two sections, one of which is slidably sleeved outside the other section. When the two sections slide relative to each other, the overall length of the crossbar 31 can be changed. The two sections of the crossbar 31 are connected by a first elastic element 32. The first elastic element 32 can be a common telescopic spring. In the natural state of the first elastic element 32, the crossbar 31 is in its longest state.

[0036] Reference Figure 1 and Figure 3 When both ends of the storage compartment 11 are closed, the connecting shaft 21 is provided with a slot 211 opposite the crossbar 31. A second elastic element 33 is installed in the slot 211. The second elastic element 33 is a telescopic spring that extends and retracts along the depth direction of the slot 211. The slot 211 has a conical flared portion 212 with a gradually increasing diameter. Both ends of the crossbar 31 are integrally formed with a locking portion 311 that matches the slot 211. In the longest state of the crossbar 31, the locking portions 311 at both ends of the crossbar 31 are located in the flared portion 212 of the corresponding connecting shaft 21. Under the action of the second elastic element 33, neither end of the crossbar 31 will be embedded in the slot 211, ensuring that the connecting shaft 21 can rotate smoothly when the user opens the first opening door 2.

[0037] Reference Figure 3 and Figure 4 When the user pulls the opening and closing door 2 to rotate, the connecting shaft 21 rotates, causing the inner wall of the flared opening to abut against the locking part 311. The inclined side wall of the flared part 212 guides the crossbar 31, causing the crossbar 31 to move to the other side of the frame 1. This causes the locking part 311 at the other end to engage in the corresponding groove 211 of the connecting shaft 21, thereby restricting the rotation of the corresponding connecting shaft 21 and achieving the aforementioned self-locking. Furthermore, the first elastic element 32 and the second elastic element 33 are in a natural state when both opening and closing doors 2 are closed, making them less prone to fatigue and resulting in a longer service life.

[0038] Reference Figure 1 As the user pulls the opening and closing door 2 to rotate around the axis of the corresponding connecting shaft 21, when the opening and closing door 2 rotates 90°, that is, when the opened opening and closing door 2 is perpendicular to the surface of the frame 1, the opening and closing door 2 abuts against the groove wall of the flared groove 14. At this time, the opening and closing door 2 is fully opened and cannot continue to rotate, so that the phenomenon of the opening and closing door 2 rotating too much and affecting the opening and closing of adjacent opening and closing doors 2 is not likely to occur.

[0039] Reference Figure 2 and Figure 3There is a clearance groove 12 between the two slides 13 corresponding to the same opening and closing door 2. The clearance groove 12 is set along the width direction of the frame 1. The fully opened opening and closing door 2 is directly opposite the clearance groove 12. At this time, the connecting shaft 21 is no longer blocked by the opening and closing door 2 and can move smoothly to the other end of the slide 13. A third elastic element 4 is installed in the clearance groove 12. The third elastic element 4 is an elastic band. One end of the third elastic element 4 is fixedly connected to the connecting shaft 21, and the other end is fixedly connected to the end of the clearance groove 12 away from the edge of the frame 1. When the connecting shaft 21 is located at the end of the slot 211 near the edge of the frame 1, the third elastic element 4 is in a stretched state. Since the fully opened door 2 is facing the clearance groove 12, the pulling force applied by the third elastic element 4 to the connecting shaft 21 is greater than the pushing force applied by the first elastic element 32 and the second elastic element 33 to the connecting shaft 21. The connecting shaft 21 and the door 2 can be smoothly pulled into the frame 1. During the process, the crossbar 31 gradually shortens until the door 2 is completely embedded in the clearance groove 12.

[0040] Reference Figure 1 and Figure 2 After the opening and closing door 2 is aligned with the clearance groove 12, the user does not need to push it into the clearance groove 12. Therefore, the user can open the storage compartment 11 by first opening the locking part 24, then pulling the opening and closing door 2 to rotate and then releasing it. This is the same as the conventional operation, requiring no additional operation, but it is less likely to cause danger and will not affect the use of adjacent storage compartments 11. Furthermore, since the opening and closing door 2 automatically retracts and hides, it solves the problem of some users forgetting or not pushing the opening and closing door 2 into the clearance groove 12 for convenience, making it more convenient to use.

[0041] Reference Figure 1 and Figure 2 To facilitate the user in pulling the opening and closing door 2 out of the clearance groove 12 when closing, a through groove 15 is connected between the storage groove 11 and the clearance groove 12 near the edge of the frame 1. A first handle 22 is fixedly installed on the inner side of the opening and closing door 2. After the opening and closing door 2 is fully retracted into the clearance groove 12, the first handle 22 is located in the through groove 15. The user can hold the first handle 22 to pull the opening and closing door 2 out of the clearance groove 12, and then manually control its rotation to close the opening of the storage groove 11.

[0042] The implementation principle of Embodiment 1 of this application is as follows: When the user opens the hinged door 2, the locking member 24 is opened first, and then the hinged door 2 is rotated, just like in conventional operation. When the user rotates the hinged door 2, the flared part 212 guides the crossbar 31, causing the crossbar 31 to move towards the hinged door at the other end of the storage compartment 11, thereby causing the locking part 311 to be embedded in the slot 211 of the corresponding connecting shaft 21, automatically achieving self-locking and reducing the possibility of both hinged doors 2 opening at the same time. The fully opened hinged door 2 is automatically retracted into the avoidance groove 12 under the pull of the third elastic member 4, reducing the occurrence of accidental collisions with the hinged door 2 or affecting the opening of adjacent hinged doors 2, thus improving the convenience of use without requiring additional operation from the user.

[0043] Example 2: Reference Figure 5 and Figure 6 The main difference between this embodiment and embodiment 1 is that the transmission structure includes an annular elastic rope 5, and the opening and closing doors 2 are all provided with through holes arranged horizontally along their own length direction. The annular elastic rope 5 is composed of two first connecting sections and two second connecting sections. The first connecting sections are movably inserted into the through holes of the opening and closing doors 2 to achieve connection with the opening and closing doors 2. The second connecting sections are movably inserted along the width direction of the frame 1, connecting the two first connecting sections into an annular shape from both sides of the width direction of the storage slot 11.

[0044] Reference Figure 5 and Figure 6 When both doors 2 are closed, the ring-shaped elastic rope 5 is in its natural state. When the user opens one of the doors 2, the ring-shaped elastic rope 5 is stretched. If the user releases the hand before the door 2 is fully opened, the elastic restoring force of the ring-shaped elastic rope 5 will automatically pull the door 2 back into the flared groove 14. Compared with the first embodiment, it is less likely that the door 2 will not automatically retract due to not being fully opened. If the user bends down or temporarily leaves to pick up an item at this time, it is also less likely to cause an accidental collision.

[0045] Reference Figure 5 and Figure 6 When the user rotates the opening and closing door 2 90° to fully open it, the opening and closing door 2 will automatically be pulled into hiding under the elastic restoring force of the ring elastic rope 5. Compared with the first embodiment, all elastic components in this embodiment, including the ring elastic rope 5, are in a natural state when the opening and closing door 2 is fully closed, and are not prone to fatigue due to long-term deformation, which affects the service life.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
