[0027] The present invention provides a mobile shelf and a transportation device. Figures 1 to 3 This is a specific embodiment of a mobile shelf provided by the present invention.

[0028] Such as Figure 1 and Figure 2As shown in the figure, an embodiment of the present utility model provides a mobile shelf 100, which includes a shelf body 1 and a locking structure 2. A plurality of universal wheels 11 are installed along the circumferential direction of the bottom of the shelf body 1. The locking structure 2 includes a locking component 21 and a cooperating component 22 that can be disposed on the shelf carrier. The locking component 21 is disposed on the shelf body 1. The locking component 21 includes a locking portion 211 that is movably disposed relative to the shelf body 1, and the locking portion 211 is detachably connected to the cooperating component 22.

[0029] In the present utility model, a plurality of universal wheels 11 are installed along the circumferential direction of the bottom of the shelf body 1. The locking structure 2 includes a locking component 21 and a cooperating component 22 that can be disposed on the shelf carrier. The locking component 21 is disposed on the shelf body 1. The locking component 21 includes a locking portion 211 that is movably disposed relative to the shelf body 1, and the locking portion 211 is detachably connected to the cooperating component 22. When loading goods, the staff can store the goods in the shelf body 1, and then drive the locking portion 211 to move to be connected to the cooperating component 22, so that the mobile shelf 100 is fixed on the shelf carrier. When it is necessary to unload the goods, the staff only needs to release the connection between the locking portion 211 and the cooperating component 22, and drive the mobile shelf 100 to the unloading location for unloading. In this application, by connecting the locking portion 211 of the locking component 21 disposed on the shelf body 1 and the cooperating component 22 disposed on the shelf carrier, the mobile shelf 100 can be stably fixed on the shelf carrier. However, the existing mobile shelves are fixed by the braking structure on the casters, which can only ensure that the casters do not rotate, and only rely on the static friction between the casters and the shelf carrier to limit the movement of the shelf, and the fixation is unstable. Further using straps for fixation will cause inconvenience in unlocking when unloading. The mobile shelf 100 and the transportation device provided by the present utility model solve the problems of unstable fixation and inconvenient unlocking of the existing mobile shelves.

[0030] Specifically, the transportation device includes, but is not limited to, a van or other transportation tools known to those skilled in the art that can transport goods.

[0031] It should be noted that at least four universal wheels 11 are installed at the bottom of the shelf body 1, and the four universal wheels 11 are respectively located at the four corners of the shelf body 1. With such a setting, the support stability of the mobile shelf 100 is ensured, and the mobile shelf 100 is prevented from tipping over when loading goods.

[0032] Further, in some embodiments, an installation groove is formed in the shelf carrier, and the cooperation component 22 is disposed in the installation groove. Since the staff needs to drive the mobile shelf 100 to move between the loading and unloading operation area and the fixed area of the shelf carrier when loading and unloading goods, by disposing the cooperation component 22 in the installation groove, it is avoided that the cooperation component 22 protrudes from the floor of the shelf carrier and interferes with the movement of the mobile shelf 100 within the shelf carrier.

[0033] Preferably, the specific structures of the locking component 21 and the cooperation component 22 are not limited, as long as the locking portion 211 of the locking component 21 is detachably connected to the cooperation component 22. For example, in some embodiments, as Figure 1 and Figure 2 shown, the locking component 21 further includes a connection seat 212. The connection seat 212 is connected to the frame body 1, and a guiding structure is provided on the connection seat 212. The guiding structure extends along the moving direction of the locking portion 211, and at least a part of the locking portion 211 penetrates through the guiding structure; the cooperation component 22 includes a housing 221 that can be connected to the shelf carrier. A cooperation hole 2211 is formed at the top of the housing 221 for at least a part of the locking portion 211 to pass through the cooperation hole 2211 and be detachably connected to the housing 221. With such a setting, the staff can drive the locking portion 211 to move on the guiding structure until it passes through the cooperation hole 2211 and is connected to the housing 221, realizing the connection between the locking component 21 and the cooperation component 22, and further enabling the mobile shelf 100 to be fixedly connected to the shelf carrier.

[0034] Further, the specific connection manner between the locking portion 211 and the housing 221 is not limited, as long as the locking portion 211 is detachably connected to the housing 221. In some embodiments, as Figure 1 and Figure 2As shown, the locking portion 211 is rotatably arranged, and the locking portion 211 includes a main body section 2111 and a locking section 2112 that are connected to each other, a clamping portion 213 is protruded from the side of the locking section 2112, and an accommodating cavity connected to the matching hole 2211 is provided in the shell 221, and the accommodating cavity has a clamping wall that limits the detachment of the clamping portion 213, so that the clamping portion 213 can pass through the matching hole 2211 and rotate to abut against the clamping wall. In this way, the shape of the matching hole 2211 is adapted to the shape of the locking portion 213. The staff first drives the locking portion 211 to make the locking portion 213 pass through the matching hole 2211 and extend into the accommodating cavity, and then rotates the locking portion 211 to make the locking portion 213 rotate until the locking portion 213 is abutted and fixed with the engaging wall, thereby connecting the locking portion 211 with the shell 221. When unlocking, the staff only needs to rotate the locking portion 211 to make the engaging portion 213 disengage from the abutting state with the engaging wall, and then make the locking segment 2112 completely disengage from the accommodating cavity to complete the unlocking.

[0035] Specifically, in some embodiments, a guide block is convexly provided on the inner wall of the accommodating cavity, the guide block is tilted downward, and the bottom of the guide block is formed with the engaging wall. The tilted guide block allows the engaging portion 213 to move along the inclined surface when rotating, making it easier to rotate to the abutting position, thereby improving the locking and unlocking efficiency of the locking portion 211 and the housing 221.

[0036] Since the locking portion 211 is in a rod shape, the staff can only rotate the locking portion 211 by pinching one end. On the one hand, the rotation is laborious, and on the other hand, the locking portion 211 may be interfered by the guide structure. Therefore, in some embodiments, Figure 2 and Figure 3 As shown, the locking assembly 21 also includes a driving part 214 connected to the main section 2111, and the locking structure 2 also includes a fixing assembly 23, and the fixing assembly 23 includes a fixing part 231 rotatably mounted on the frame body 1, and the fixing part 231 is detachably connected to the driving part 214. In this way, on the one hand, by setting the driving part 214 connected to the main section 2111 of the locking part 211, it is more labor-saving for the staff to drive the locking part 211 to move and rotate, and it will not be interfered by the guide structure, and the efficiency of locking and unlocking is higher. On the other hand, the fixing part 231 detachably connected to the driving part 214 is set to avoid the movement of the driving part 214 due to the bumps of the shelf carrier during driving, which eventually causes the locking assembly 21 to be disconnected from the matching assembly 22, and the driving part 214 is connected to the fixing part 231 to make the fixing of the mobile shelf 100 more secure.

[0037] Specifically, the driving part 214 is provided with a through hole, the shape of the through hole is adapted to the shape of the fixing part 231, and the fixing part 231 passes through the through hole and rotates to abut against the end face of the driving part 214, so as to realize the reliable connection between the driving part 214 and the fixing part 231.

[0038] Since the mobile rack 100 has a need for temporary fixation in some usage scenarios, in some embodiments, such as Figure 2 and Figure 3 shown, the fixing assembly 23 further includes a fixing seat 232 provided on the rack body 1, the fixing part 231 is rotatably installed on the fixing seat 232, the fixing seat 232 is provided with a clamping part 233, the clamping part 233 is located above the fixing part 231, and has a clamping groove for a part of the driving part 214 to extend into and abut against. With such a setting, when the mobile rack 100 needs to be reliably fixed, the staff drives the locking part 211 to move and rotate, so that the engaging part 213 abuts against the engaging wall, and at the same time connects the driving part 214 and the fixing part 231; when the mobile rack 100 needs to be temporarily fixed, the staff only needs to drive the locking part 211 to move, so that a part of the locking section 2112 passes through the mating hole 2211 and extends into the accommodating cavity, and at the same time the driving part 214 extends into the clamping groove and abuts against it. The clamping groove can only limit the rotation of the driving part 214. When the staff releases the temporary fixation, they only need to drive the locking part 211 to move away from the mating assembly 22.

[0039] In order to ensure the smooth movement of the locking part 211, considering the production tolerance, there is a certain gap between the locking part 211 and the mating hole 2211. Therefore, in some embodiments, such as Figure 2 shown, the mating assembly 22 further includes a limiting part 222, the limiting part 222 is provided in the accommodating cavity, and is provided with a limiting groove for the free end of the locking section 2112 to extend into. The limiting groove has a limiting wall for restricting the movement of the locking section 2112 in the horizontal direction. With such a setting, the movement of the locking section 2112 in the horizontal direction is restricted by the limiting groove on the limiting part 222, thereby making the connection between the locking part 211 and the housing 221 more firm.

[0040] When there are a large number of goods transported by the shelf carrier, one layer of the mobile rack 100 cannot meet the storage needs of the goods, and it is necessary to stack another layer of mobile rack 100 on the mobile rack 100. Therefore, in some embodiments, such as Figure 1As shown, a plurality of positioning portions 4 protrude from the top of the frame body 1, and a plurality of positioning grooves are formed at the bottom. Each of the positioning grooves corresponds to one of the positioning portions 4, and is configured for the positioning portion 4 to extend into the positioning groove of another mobile rack 100 for connection and fixation. With such a setting, through the cooperation of the positioning portion 4 and the positioning groove, the upper-layer mobile rack 100 is connected to the lower-layer mobile rack 100, preventing the upper-layer mobile rack 100 from tipping over.

[0041] In order to improve the unloading efficiency of the staff, in some embodiments, as Figure 1 shown, the frame body 1 includes a base 12, two side enclosing portions 13, and an intermediate enclosing portion 14 disposed between the two side enclosing portions 13. The two side enclosing portions 13 are oppositely arranged on the base 12. The intermediate enclosing portion 14 is hinged to the base 12 and is detachably connected to the two side enclosing portions 13 respectively. When the staff unloads goods, the connection between the intermediate enclosing portion 14 and the two side enclosing portions 13 can be directly released, enabling the staff to unload goods from the openings on both sides of the mobile rack 100, greatly improving the unloading efficiency.

[0042] Furthermore, as Figure 1 shown, a handle is provided on the intermediate enclosing portion 14, facilitating the staff to drive the mobile rack 100 to move between the loading and unloading operation area and the rack carrier.

[0043] In order to enhance the reliability of the fixation of the mobile rack 100, in some embodiments, as Figure 1 shown, positioning holes 15 are formed in the side portion of the frame body 1 for the positioning pins on the rack carrier to pass through and be fixed. The positioning pins are disposed on the side wall of the rack carrier. The staff first passes the positioning pins through the positioning holes 15, and then connects the locking assembly 21 and the mating assembly 22. On the one hand, it improves the positioning of the positioning pins and the positioning holes 15, enabling the locking assembly 21 to be above the mating assembly 22, saving the time for alignment, thereby enhancing the locking efficiency. On the other hand, it increases the connection points between the mobile rack 100 and the rack carrier, enhancing the reliability of the fixation of the mobile rack 100.

[0044] In addition, the present utility model also provides a transportation device, including a rack carrier and the mobile rack 100. The mobile rack 100 includes a frame body 1 and a locking structure 2. A plurality of universal wheels 11 are installed along the circumferential direction of the bottom of the frame body 1. The locking structure 2 includes a locking assembly 21 and a mating assembly 22 that can be disposed on the rack carrier. The locking assembly 21 is disposed on the frame body 1. The locking assembly 21 includes a locking portion 211 that moves relative to the frame body 1, and the locking portion 211 is detachably connected to the mating assembly 22.

[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
