[0046] The following is combined Figures 1 to 10 This invention describes a storage box.

[0047] This utility model provides a storage box, including a first box body 100, a plurality of second boxes body 200 and a first locking component 300.

[0048] The first box 100 has a first telescopic rod 110 at the top near the rear side, and at least the bottom of the first box 100 has a first roller assembly 120 at the bottom near the rear side. The front, left or right side of the first box 100 is open, and a plurality of first receiving slots 130 extending into the interior of the first box 100 are provided on the open side.

[0049] Specifically, the first box 100 can be a rectangular box structure. The front side of the first box 100 can be provided with four first receiving slots 130. The four first receiving slots 130 are distributed in the vertical direction and extend from the front side to the rear side. The front side of the first receiving slots 130 is open.

[0050] A first telescopic rod 110 is provided on the first housing 100. The first telescopic rod 110 is located on the top surface of the first housing 100 near the rear side and in the middle position along the left and right direction. The first telescopic rod 110 can extend upward and retract downward to a position where the top is flush with the top surface of the first housing 100.

[0051] A first roller assembly 120 is also provided on the first housing 100. Two first roller assemblies 120 can be provided, located on the bottom surface of the first housing 100 near the rear side, and positioned on the left and right sides respectively. Alternatively, four first roller assemblies 120 can be provided, located on the bottom surface of the first housing 100 near the four corners.

[0052] Of course, the first receiving slot 130 mentioned above can also be opened on the left or right side of the first housing 100.

[0053] Multiple second boxes 200 correspond one-to-one with multiple first receiving slots 130, and the second boxes 200 are used to be inserted into the first receiving slots 130 or to be pulled out from the first receiving slots 130. The second boxes 200 are provided with openable and closable item loading and unloading ports, and the second boxes 200 are provided with item fixing devices.

[0054] Specifically, a second box 200 is correspondingly provided in each first receiving slot 130. The external dimensions of the second box 200 are the same as the external dimensions of the first receiving slot 130. When the second box 200 is placed in the first receiving slot 130, the outer side of the second box 200 fits against the inner side of the first receiving slot 130, and the front side of the second box 200 is flush with the front side of the first box 100. The second box 200 can be inserted into the first receiving slot 130 or pulled out from the first receiving slot 130.

[0055] The second housing 200 includes a receiving section and a lid. The top of the receiving section is open, and the lid and receiving section are designed to be opened and closed. An item securing device is provided inside the receiving section to secure the medical device and prevent relative movement between the medical device and the second housing 200 during transfer, thus protecting the medical device.

[0056] A first locking component 300 is disposed between the first housing 100 and the second housing 200 to restrict or release the relative movement between the first housing 100 and the second housing 200. For example, the first locking component 300 can be a latch.

[0057] When the second box 200 is placed into the first receiving slot 130 of the first box 100, the box buckle can be locked to prevent the second box 200 from falling out of the first receiving slot 130. When it is necessary to remove the second box 200, the box buckle can be unlocked to allow the first box 100 and the second box 200 to move relative to each other.

[0058] The storage box provided by this utility model allows medical devices to be placed separately inside the second box 200, and the second box 200 can be completely stored inside the first box 100, thus saving space. Furthermore, the inclusion of a first telescopic rod 110 and a first roller assembly 120 facilitates its movement.

[0059] In some embodiments, the article fixing device may include a first sliding limit component, a second sliding limit component, and a second locking component.

[0060] The first sliding limit assembly includes a pair of first slide rails 211 and a pair of first partitions 212. The two first slide rails 211 are respectively disposed on the inner sidewalls of the front and rear sides of the second housing 200 and extend in the left and right direction. The front and rear sides of the first partitions 212 are slidably connected to the two first slide rails 211 respectively. The first partitions 212 are disposed in the vertical direction. The first partitions 212 are provided with a plurality of first clearance grooves 213 extending in the front and rear direction and penetrating the first partitions 212 in the left and right direction.

[0061] Specifically, two first slide rails 211 are respectively disposed on the inner sidewalls of the front and rear sides of the second housing 200, and are set at the same height. Both first slide rails 211 extend in the left-right direction, and the front and rear sides of the first partition 212 are slidably connected to the first slide rails 211. For example, the first partition 212 and the first slide rails 211 can be a slider and a groove structure, so that the first partition 212 can slide in the left-right direction.

[0062] The first partition 212 is arranged vertically, and a plurality of first clearance grooves 213 are provided on the first partition 212. The plurality of first clearance grooves 213 extend in the front-back direction and penetrate the first partition 212 in the left-right direction.

[0063] The second sliding limit assembly includes a pair of second slide rails 221 and a pair of second partitions 222. The two second slide rails 221 are respectively disposed on the inner sidewalls of the left and right sides of the second housing 200 and extend in the front-back direction. The left and right sides of the second partitions 222 are slidably connected to the two second slide rails 221 respectively. The second partitions 222 are disposed in the vertical direction. The second partitions 222 are provided with a plurality of second clearance grooves 223 that extend in the left-right direction and penetrate the second partitions 222 in the front-back direction.

[0064] Specifically, two second slide rails 221 are respectively disposed on the inner sidewalls of the left and right sides of the second housing 200, and are set at the same height. Both second slide rails 221 extend in the front-back direction, and the left and right sides of the second partition 222 are slidably connected to the second slide rails 221. For example, the second partition 222 and the second slide rail 221 can be a slider and a groove structure, so that the second partition 222 can slide in the front-back direction.

[0065] The second partition 222 is arranged vertically, and a plurality of second clearance grooves 223 are provided on the second partition 222. The plurality of second clearance grooves 223 extend in the front-back direction and penetrate the first partition 212 in the left-right direction.

[0066] The second clearance groove 223 and the first clearance groove 213 are alternately arranged vertically, so that the first partition 212 can slide relative to the second partition 222 in the left-right direction through the second clearance groove 223, and the second partition 222 can slide relative to the first partition 212 in the front-back direction through the first clearance groove 213, thus preventing interference between the two.

[0067] The first partition 212 and the second partition 222 are slidably arranged so as to adjust the space between the four partitions so that all four partitions are in contact with the edge of the medical device to be stored, thereby restricting the movement of the medical device.

[0068] To enable the first partition 212 and the second partition 222 to function as limiting elements, second locking components are also required between the first partition 212 and the first slide rail 211, and between the second partition 222 and the second slide rail 221. When the second locking components are locked, they can restrict the relative sliding between the first partition 212 and the first slide rail 211, or restrict the relative sliding between the second partition 222 and the second slide rail 221. When the second locking components are unlocked, the first partition 212 can slide freely along the first slide rail 211, or the second partition 222 can slide freely along the second slide rail 221.

[0069] Taking the second locking assembly between the first partition 212 and the first slide rail 211 as an example, the second locking assembly may include a positioning block 231 and a positioning bolt 232. The positioning block 231 is located on the left or right side of the first partition 212 near the first slide rail 211. A bolt hole extending through the positioning block 231 in the front-to-back direction is provided on the positioning block 231, and the positioning bolt 232 passes through the bolt hole. When the second locking assembly needs to be locked, the positioning bolt 232 can be rotated to abut against the first slide rail 211, and the movement of the first partition 212 is restricted by the friction between the positioning bolt 232 and the first slide rail 211. When the positioning bolt 232 rotates in the opposite direction and separates from the first slide rail 211, the first partition 212 can slide freely relative to the first slide rail 211.

[0070] In some embodiments, a second receiving groove 140 is provided at the bottom or side of the first housing 100, and the first roller assembly 120 is connected to the first housing 100 through a folding mechanism. The folding mechanism is used to switch the first roller assembly 120 between a hidden position and a working position. When the folding mechanism is in the hidden position, both the folding mechanism and the first roller assembly 120 are located in the second receiving groove 140.

[0071] Specifically, taking the bottom of the first housing 100 as an example, where two first roller assemblies 120 are provided, the second receiving groove 140 can be provided at the bottom of the first housing 100, with one of the second receiving grooves 140 located to the right of the left first roller assembly 120 and the other second receiving groove 140 located to the left of the right first roller assembly 120.

[0072] When the first roller assembly 120 is folded into the second receiving slot 140 by the folding mechanism, the first roller assembly 120 and the folding mechanism are all located in the first receiving slot 130 and will not extend beyond the outer side of the first box 100, thus facilitating the stacking of multiple first boxes 100.

[0073] The folding mechanism includes a rotating rod 420 and a positioning rod 410.

[0074] Taking the first roller assembly 120 located on the left as an example, one end of the rotating rod 420 is rotatably connected to the first housing 100, with the rotation axis along the front-rear direction. The rotating rod 420 is connected to the bottom of the second receiving groove 140 located on the left side, near the left side, and is located in the middle position of the second receiving groove 140 along the front-rear direction. The other end of the rotating rod 420 is used to connect to the first roller assembly 120. A first insertion hole 430 and a second insertion hole 440 are provided on the rear side of the rotating rod 420. The first insertion hole 430 can be located near the first roller assembly 120, and the second insertion hole 440 can be located near the first housing 100. The axes of the first insertion hole 430 and the second insertion hole 440 both extend along the front-rear direction. A third insertion hole is provided on the right side of the bottom of the second receiving groove 140, at the middle position along the front-rear direction.

[0075] The positioning rod 410 has two connectors 450 at both ends. The two connectors 450 extend in parallel directions and are located on the same side of the positioning rod 410.

[0076] When the folding mechanism is in the hidden position, the connectors 450 at both ends of the positioning rod 410 can be inserted into the first connector hole 430 and the second connector hole 440 respectively. At this time, the positioning rod 410 and the rotating rod 420 are an integral structure and are parallel to each other. The first roller assembly 120 can be rotated into the second receiving groove 140 and hidden by the rotating rod 420.

[0077] When the folding mechanism is in the working position, the connector 450 at one end of the positioning rod 410 can be inserted into the first insertion hole 430, and the connector 450 at the other end can be inserted into the third insertion hole. At this time, the positioning rod 410, the rotating rod 420 and the bottom of the second receiving groove 140 form a stable triangular structure, so that the rotating rod 420 is stably supported at the bottom of the first box 100.

[0078] In some embodiments, taking the second receiving groove 140 as being located at the bottom of the box as an example, the front and rear sides of the second receiving groove 140 are provided with limiting protrusions 141. When the positioning rod 410 is connected to the rotating rod 420 and rotates with the rotating rod 420 into the second receiving groove 140, the limiting protrusions 141 are interference-fitted with the rotating rod 420 and the positioning rod 410, so that the limiting protrusions 141 are clamped on both sides of the rotating rod 420 and the positioning rod 410, preventing the rotating rod 420 from rotating out of the second receiving groove 140.

[0079] In some embodiments, a handle 240 is provided on the side of the second housing 200 near the opening of the first receiving groove 130.

[0080] Specifically, taking the opening of the first receiving slot 130 located on the front side of the first box 100 as an example, a handle 240 is provided at the center of the front side of the first box 100. The handle 240 facilitates the second box 200 to be taken out and put into the first receiving slot 130, and also facilitates the second box 200 to be lifted and transferred after being pulled out.

[0081] In some embodiments, a second roller assembly 250 is provided on the side of the second housing 200 away from the opening of the first receiving groove 130.

[0082] Specifically, the second housing 200 can be a cuboid structure. Four second roller assemblies 250 can be provided on the side of the second housing 200 away from the opening of the first receiving groove 130, and four fourth roller assemblies are respectively provided at the four corners of this side. This facilitates the movement of the second housing 200.
