Description

Technical Field

[0001] The present invention belongs to the technical field of logistics box delivery, and in particular relates to an Internet-based logistics box delivery logistics rack. Background Art

[0002] Logistics boxes are widely used in various industries. They are resistant to acids, alkalis, and oils, are non-toxic and odorless, can be used to hold food, etc., are easy to clean and easy to manage. Their reasonable design and excellent quality make them suitable for transportation, distribution, storage, circulation and processing in factory logistics. Logistics boxes can be combined with a variety of logistics containers and workstation equipment and used in various warehouses, production sites and other occasions. Therefore, the existing products are all packaged in logistics boxes required by different industries, and the logistics boxes in the warehouses are placed with logistics racks that match them one after another.

[0003] Since the sizes of existing logistics racks are mostly fixed, the sizes of the logistics racks cannot be adjusted according to the material boxes or logistics items to be delivered, and thus a larger logistics rack needs to be replaced, which is difficult to reuse. If the symmetrical support rods on the logistics rack are disassembled, the safe delivery of the logistics boxes or logistics items will be affected. Although the existing logistics racks can be adjusted in size, they can only increase the length of the logistics rack, and cannot synchronously adjust the length or width of the logistics rack according to the width or length of the logistics boxes or logistics items to be delivered, so that the logistics rack can deliver logistics boxes of different sizes or material items without a shell. Summary of the invention

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The present invention is an Internet-based logistics box delivery logistics rack, comprising a first bottom plate and a second bottom plate, and movable wheels are installed on the lower surface of each bottom plate, square support rods are vertically installed at the four corners of the upper surfaces of the first bottom plate and the second bottom plate, at least three groups of support and disassembly components are equidistantly arranged on the square support rods, and at least three groups of telescopic cross rods are detachably installed between every two of the square support rods through at least three groups of support and disassembly components, and support shaft rods are vertically inserted into the two square support rods that are in contact with each other on the front sides of the first bottom plate and the second bottom plate, and the top end of the support shaft rod extends out of the upper surface of the square support rod, and the bottom end thereof extends out of the lower surfaces of the two bottom plates, and the upper and lower ends of the two support shaft rods are respectively rotatably locked and connected to each other by rotating locking components.

[0006] Furthermore, the support and disassembly assembly includes a rotating shaft rod, a square sleeve, a supporting ear plate, a connecting bolt and a first locking screw. Each of the square support rods is arranged in sections, and the upper and lower sections of the square support rods are connected by a rotating shaft rod. Each of the rotating shaft rods is rotatably sleeved with a square sleeve, and each rotating shaft rod is provided with two threaded holes, and the openings of the two threaded holes are both opened outward. Through holes are provided on the two outer sides of the square sleeve, and the through holes are aligned with the threaded holes. Support ear plates are fixed on the other two side surfaces of the bottom of the square sleeve, and bolt holes are also provided on each support ear plate. The two end portions of each of the telescopic cross rods are detachably connected to the support ear plates by two connecting bolts, and the square sleeve is connected to the threaded hole provided on the rotating shaft rod by the first locking screw.

[0007] Furthermore, the telescopic cross rod includes a square rod sleeve, an end square rod, a square blocking sleeve and a sliding plug. The two ends of the square rod sleeve are slidably inserted with end square rods of equal length, and the end square rods are located at the inner ends of the square rod sleeve and fixed with sliding plugs. The two ends of the square rod sleeve are installed with square blocking sleeves. The ends of the end square rods away from the square rod sleeve are provided with locking holes for connecting bolts to pass through. The maximum elongation of the two end square rods and the square rod sleeve is greater than the distance between the left and right square support rods, and the minimum elongation of the two end square rods and the square rod sleeve is less than the distance between the front and rear square support rods.

[0008] The cam is secured to the bottom of the second support bracket and is designed to be pivotally connected to the second support bracket of the second cam.

[0009] Furthermore, the rotation locking assembly also includes a locking strip, the length of which is equal to the distance between two mutually adjacent square support rods, and the locking strip is fixed to the outer side surfaces of the two mutually adjacent square support rods by a first locking screw.

[0010] Furthermore, airbag strips are fixed to the mutually contacting sides of the first bottom plate and the second bottom plate, and inflation tubes are installed at the rear ends of the two airbag strips, and sealing plugs are installed on the inflation tubes. The two airbag strips contact each other after being inflated.

[0011] Furthermore, two threaded mounting holes are provided on the upper surfaces of the left side wall and the rear side wall of the first bottom plate, and the distance between the two threaded mounting holes is the same. A push handle is detachably mounted on the first bottom plate through screws and the threaded mounting holes.

[0012] Furthermore, when the first bottom plate and the second bottom plate are connected side by side, the support plates are detachably mounted on the support ear plates corresponding to the inner side surfaces of the symmetrical square support rods through connecting bolts.

[0013] The present invention has the following beneficial effects:

[0014] 1. The present invention opens the rotating locking assembly by installing the two end portions of the supporting shaft rods inside the two adjacent square support rods on the front side, so that the second bottom plate on the right side can be rotated 180 degrees counterclockwise around the supporting shaft rod on the square support rod on the front side of the first bottom plate, so that the second bottom plate located on the front side can be attached to the right side of the first bottom plate, and then the rotating locking assembly is locked, so that the first bottom plate and the second bottom plate arranged side by side on the left and right are connected to each other to form a whole, and then the disassembled telescopic cross bar is installed on the front side of the first bottom plate and the left and right symmetrical square support rods on the front and rear sides of the second bottom plate, so that the overall length of the connected logistics rack can be increased, which is convenient for storing and delivering logistics boxes with longer lengths or logistics items without shells, and there is no need to customize or disassemble and assemble the logistics rack according to the size of the logistics box alone, thereby improving the storage and delivery efficiency of the logistics rack for logistics boxes of different sizes, and also improving the utilization rate of the assembled and connected logistics rack.

[0015] 2. The present invention cooperates with the tensioning screw and the second locking screw on the connecting strip, and loosens the second locking screw to make the pressure plate disengage from the compression fixation of the rotating sleeve. Loosening the tensioning screw allows the tensioning spring to be in a relaxed state, allowing the rotating sleeve to slide in the sliding guide groove, and then pulls the second base plate to make it away from the side of the first base plate. Then, the second base plate is rotated 180° counterclockwise or clockwise as needed, so that the first base plate and the second base plate are adjusted side by side, and then the tensioning screw and the second locking screw are twisted respectively so that the rotating sleeve can be fixed to the connecting strip, thereby realizing the limit fixation of the support shaft rod on the first base plate and the support shaft rod on the second base plate, thereby facilitating the limit fixation of the two side-by-side connected logistics racks, preventing the side-by-side connected logistics racks from detaching during movement, thereby affecting the delivery processing of the logistics racks to the logistics boxes.

[0016] 3. The present invention cooperates with the telescopic cross bar and the support disassembly assembly. Since the maximum elongation of the end square bar and the square rod sleeve is greater than the distance between the left and right square support rods, and the minimum elongation of the two end square bars and the square rod sleeve is less than the distance between the front and rear square support rods, the telescopic cross bar disassembled from the front and rear square support rods can be installed to the left and right square support rods in a stretched state, so that the disassembled telescopic cross bar can be adjusted in length according to the adjustment state of the logistics rack without replacing a new cross bar, thereby improving the reuse rate of the telescopic cross bar on the logistics rack and preventing the cross bar disassembled from the logistics rack from being unable to continue to be used following the adjustment of the width or length of the logistics rack, thereby causing unnecessary waste.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When a longer logistics box or a logistics item without a shell needs to be delivered, the multiple telescopic cross bars 5 that need to be arranged side by side and on the rightmost side after being arranged side by side can be disassembled through the support disassembly assembly 4, and then the rotation locking assembly 7 is opened, and then the logistics rack on the front side is rotated 180° counterclockwise, and the mobile wheel 10 with a universal function can play a role in assisting the rotation, thereby making the logistics rack on the front side The rack is rotated to the right side of the rear logistics rack, and then the rotation locking assembly 7 is locked, so that the first bottom plate 1 and the second bottom plate 2 arranged side by side on the left and right are connected to each other to form a whole, so that the overall length of the connected logistics rack can be lengthened, so as to facilitate the delivery and processing of logistics boxes with longer lengths or logistics items in the form of plates without shells. When the first bottom plate 1 and the second bottom plate 2 are arranged side by side on the left and right, the multiple telescopic cross bars 5 can be disassembled and installed on the square support bars 3 on the front side of the first bottom plate 1 and the front and rear sides of the second bottom plate 2 arranged side by side on the left and right, so as to facilitate the blocking of the vertical racks on both sides of the logistics rack after the length adjustment, to prevent When a longer logistics box or a plate-shaped logistics item without a shell is placed on the logistics rack after the length is adjusted, the logistics box or logistics item will fall off the logistics rack; and when a wider logistics box or logistics item needs to be delivered, the telescopic cross bar 5 on the front side of the first bottom plate 1 and the front and rear sides of the second bottom plate 2 are removed from the support disassembly component 4, and then the rotation locking component 7 is opened, so that the second bottom plate 2 on the right side can be rotated 180° clockwise around the support shaft rod 6 on the square support rod 3 on the front side of the first bottom plate 1, so that the second bottom plate 2 on the right side can be attached to the front side of the first bottom plate 1, and then Then, the rotating locking assembly 7 is locked so that the first bottom plate 1 and the second bottom plate 2 arranged side by side are connected to each other to form a whole, and then the disassembled telescopic cross bar 5 is installed to the right side of the first bottom plate 1 and the left and right sides of the second bottom plate 2, so as to increase the overall width of the connected logistics rack, thereby facilitating the storage and delivery of wider logistics boxes or logistics items without shells, and there is no need to customize or disassemble and assemble the logistics rack according to the size of the logistics box, thereby improving the storage and delivery efficiency of the logistics rack for logistics boxes of different sizes, and also improving the utilization rate of the assembled and connected logistics rack.

[0030] As an embodiment of the present invention, the support disassembly assembly 4 includes a rotating shaft rod 41, a square sleeve 42, a supporting ear plate 43, a connecting bolt 44 and a first locking screw 45. Each of the square support rods 3 is arranged in sections, and the upper and lower sections of the square support rods 3 are connected by the rotating shaft rod 41. A rotating sleeve 72 is connected to the square sleeve 42 on each of the rotating shaft rods 41, and two threaded holes 411 are provided on each of the rotating shaft rods 41, and the openings of the two threaded holes 411 are both opened outwardly. Through holes 421 are provided on the two outer sides of the square sleeve 42, and the through holes 421 are aligned with the threaded holes 411. Support ear plates 43 are fixed to the other two side surfaces of the bottom of the square sleeve 42, and each support ear plate 43 is also provided with a bolt hole 431. The two ends of each of the telescopic cross bars 5 are detachably connected to the supporting ear plates 43 by two connecting bolts 44, and the square sleeve 42 is connected to the threaded hole 411 provided on the rotating shaft rod 41 by the first locking screw 45.

[0031] In the scheme designed by the present invention, when it is necessary to disassemble the telescopic cross bar 5, the nuts of the connecting bolts 44 are first disassembled, and then the bolt bodies of the connecting bolts 44 are pulled out from the bolt holes 431 opened on the two ends of the telescopic cross bar 5 and the supporting ear plates 43, so as to facilitate the removal of the telescopic cross bar 5 from the supporting ear plates 43 on the sides of the two square sleeves 42, and the square sleeves 42 are connected to the shaft rod 41 by the rotating sleeves 72, so as to facilitate the adjustment of the positions of the corresponding supporting ear plates 43 on the two square support rods 3, so that the two ends of the telescopic cross bar 5 after disassembly can be quickly and accurately installed between the two square support rods 3 through the cooperation of the connecting bolts 44 and the supporting ear plates 43, and then the square sleeves 42 are fixed to the shaft rod 41 by the first locking bolts, so as to further improve the firmness of the installation of the telescopic cross bar 5 between the two square support rods 3.

The two ends of the square rod sleeve 51 are slidably inserted with the end square rods 52 of equal length, and the end square rods 52 are located at the inner ends of the square rod sleeve 51 and fixed with sliding plugs 54. The two ends of the square rod sleeve 51 are installed with square blocking sleeves 53. The ends of the end square rods 52 away from the square rod sleeve 51 are provided with locking holes 521 for the connecting bolts 44 to pass through. The maximum elongation of the two end square rods 52 and the square rod sleeve 51 is greater than the distance between the left and right square support rods 3, and the minimum elongation of the two end square rods 52 and the square rod sleeve 51 is less than the distance between the front and rear square support rods 3.

[0033] In the solution designed by the present invention, when the two ends of the end square rod 52 are removed from the two supporting ear plates 43, the telescopic cross bar 5 formed by the square rod sleeve 51 and the end square rod 52 will be simultaneously removed from the two square support rods 3. If the telescopic cross bar 5 is removed from the front and rear two square support rods 3 and needs to be installed on the left and right square support rods 3, the two end square rods 52 need to be simultaneously pulled out from the square rod sleeve 51, and the sliding plug 54 will slide in the square rod sleeve 51, and the square blocking sleeve 53 will block the sliding plug 54, so that the end square rod 52 will not be detached from the square rod sleeve 51, and the two square support rods 3 can be pulled out. The overall length of the end square rod 52 and the square rod sleeve 51 can match the left and right square support rods 3, and then the two pulled-out end square rods 52 are fixed to the supporting ear plates 43, so that the telescopic cross bar 5 disassembled from the front and rear square support rods 3 can be installed to the left and right square support rods 3 in a stretched state, so that the disassembled telescopic cross bar 5 can be adjusted in length according to the adjustment state of the logistics rack, and there is no need to replace a new cross bar, thereby improving the reuse rate of the telescopic cross bar 5 on the logistics rack and preventing the cross bar disassembled from the logistics rack from being unable to continue to be used following the adjustment of the width or length of the logistics rack, thereby causing unnecessary waste.

The two connecting strips 71 are fixedly mounted to the two ends of the support shaft 6 vertically mounted on the second base plate 2, and each connecting strip 71 has a sliding guide groove 711 at the other end thereof along its length direction, and a rotating sleeve 72 is slidably mounted in the sliding guide groove 711. The rotating sleeve 72 is connected to the support shaft 6 vertically mounted on the first base plate 1. At the end of the support shaft rod 6, the outer ring surface of the rotating sleeve 72 is fixed with a limiting arc block 73, and the outer end of the limiting arc block 73 is horizontally installed with a tensioning spring 74, and the other end surface of the tensioning spring 74 is installed with a pushing block 75, and the outer side surface of the pushing block 75 is rotatably connected to the end of a tensioning screw 76, and the second tensioning screw 76 is threadedly connected to the left groove wall of the sliding guide groove 711, and its head extends out of the sliding guide groove 711, and the end surface of the rotating sleeve 72 is fitted with a clamping plate 77, and the clamping plate 77 is installed to the end surface of the support shaft rod 6 sleeved by the rotating sleeve 72 through a locking screw;

[0035] When the left front end of the second base plate 2 needs to rotate around the right front end of the first base plate 1, the second locking screw 78 is first loosened to disengage the clamping plate 77 from the clamping fixation on the rotating sleeve 72, and then the tensioning screws 76 on the sides of the upper and lower connecting strips 71 are loosened to allow the tensioning spring 74 to be in a relaxed state, so that the rotating sleeve 72 can slide in the sliding guide groove 711, and then the second base plate 2 is pulled to move away from the side of the first base plate 1, and then the second base plate 2 is rotated 180° counterclockwise or clockwise as needed, so that when the left front end of the second base plate 2 rotates, the right front end of the first base plate 1 will not interfere, and then the supporting shaft rod on the second base plate 2 will rotate around the supporting shaft rod 6 on the first base plate 1 through the connecting strip 71 and the rotating sleeve 72, so that the first base plate 1 and the second base The plates 2 are adjusted side by side left and right. When the two logistics racks are side by side left and right, the upper and lower connecting strips 71 will be in a horizontal state left and right, and then the logistics rack on the right will be pushed, so that the second bottom plate 2 is close to the first bottom plate 1, and the rotating sleeve 72 will contact the groove wall of the sliding guide groove 711, and then the tensioning screw 76 is twisted so that the pushing block 75 pushes the tensioning spring 74 to compress, and then the limiting arc block 73 will limit and fix the rotating sleeve 72, and then the second locking screw 78 is twisted so that the clamping plate 77 is pressed and fixed to the rotating sleeve 72, thereby realizing the limit fixation of the support shaft 6 on the first bottom plate 1 and the support shaft 6 on the second bottom plate 2, so as to facilitate the limit fixation of the two side-by-side connected logistics racks, and prevent the side-by-side connected logistics racks from detaching during movement, thereby affecting the logistics rack's delivery and processing of the logistics box.

[0036] As an embodiment of the present invention, the rotation locking assembly 7 further includes a locking strip 79, the length of which is equal to the distance between two mutually adjacent square support rods 3, and the locking strip 79 is fixed to the outer side surfaces of the two mutually adjacent square support rods 3 by a first locking screw 45;

[0037] In the scheme designed by the present invention, when the first base plate 1 and the second base plate 2 are connected side by side by rotating the locking assembly 7, in order to improve the firmness of the connection between the two side-by-side logistics racks, the corresponding first locking screws 45 on the two adjacent square support rods 3 can be removed at this time, and then the locking strip 79 can be horizontally attached to the outer side surfaces of the two adjacent square sleeves 42, and the holes opened on the locking strip 79 are aligned with the through holes 421 opened on the square sleeves 42, and then the first locking screw 45 is connected to the corresponding threaded hole 411, so that not only the square sleeves 42 can be fixed, but also the locking strip 79 can be fixed to the two adjacent square sleeves. The two square support rods 3 that are close to each other can be fixedly connected, thereby further improving the firmness and stability of the connection between the side-by-side first base plate 1 and the second base plate 2, so that the two side-by-side logistics racks can stably and safely deliver the logistics boxes; and when it is necessary to adjust the two logistics racks to be connected front to back side by side, at this time, the multiple locking strips 79 are first removed from the two square support rods 3 that are close to each other, and then the corresponding parts on the connecting strips 71 are loosened and removed, thereby facilitating the adjustment of the two side-by-side logistics racks to be connected front to back side by side, thereby facilitating the delivery of logistics boxes of different specifications or logistics items without a shell.

[0038] As an embodiment of the present invention, airbag strips 8 are fixed to the sides of the first bottom plate 1 and the second bottom plate 2 that are in contact with each other, and inflation tubes are installed at the rear ends of the two airbag strips 8, and sealing plugs are installed on the inflation tubes. The two airbag strips 8 are in contact with each other after being inflated; in the design scheme of the present invention, in order to prevent the end faces of the first bottom plate 1 and the second bottom plate 2 that are close to each other from having gaps, which may cause the stored logistics boxes to fall, when the first bottom plate 1 and the second bottom plate 2 are connected side by side, the air pump can be used to connect with the two inflation tubes respectively, so that the two airbag strips 8 are inflated at the same time and are in contact with each other, thereby reducing the gap between the first bottom plate 1 and the second bottom plate 2. At the same time, the mutual squeezing force of the two airbag strips 8 when they are inflated can act on the first bottom plate 1 and the second bottom plate 2, thereby improving the firmness and stability of the connection of the locking strip 79 on the two square support rods 3 that are close to each other.

[0039] As an embodiment of the present invention, two threaded mounting holes 11 are provided on the left side wall and the upper surface of the rear side wall of the first base plate 1, and the distances between the two threaded mounting holes 11 are the same, and a push handle 9 is detachably installed on the first base plate 1 through screws and the threaded mounting holes 11; in the design scheme of the present invention, when the first base plate 1 and the second base plate 2 are connected side by side left and right, the push handle 9 can be fixed to the threaded mounting hole 11 provided on the upper surface of the left side of the first base plate 1 by screws, so as to facilitate the logistics personnel to push the logistics racks arranged side by side on the left side to move and deliver them; and when the second base plate 2 is connected side by side to the front side of the first base plate 1, the push handle 9 is disassembled and installed in the corresponding threaded mounting hole 11 on the upper surface of the rear side of the first base plate 1, so as to facilitate the push of the logistics racks arranged side by side front and back to move and deliver them.

[0040] As an embodiment of the present invention, when the first bottom plate 1 and the second bottom plate 2 are connected side by side, the support plate 20 is detachably mounted on the support ear plate 43 corresponding to the inner side surface of the symmetrical square support rod 3 through the connecting bolt 44;

[0041] In the scheme designed by the present invention, taking the left and right side-by-side connection as an example, when the first bottom plate 1 and the second bottom plate 2 are connected side by side, the operator can fix the support plate 20 on the support ear plate 43 corresponding to the inner side surface of the front and rear symmetrical square support rods 3 according to the needs of the logistics box to be delivered, so that the logistics rack connected side by side on the left and right can be separated into upper and lower spaces, so that the logistics boxes or logistics items can be delivered in layers; and the support ear plates 43 on the square support rods 3 are provided with at least three groups, so that at least three layers of support plates 20 can be installed in the logistics rack as needed, thereby increasing the logistics rack's support for the logistics box. The delivery space of the flow box, and since the telescopic cross bar 5 is connected to the symmetrical square support rod 3 on the far left above the first bottom plate 1, the support plate 20 can be installed on the telescopic cross bar 5 and the support ear plate 43 by using a longer connecting bolt 44, so as to achieve stable and safe support for the installed support plate 20; the support plate 20 can also be installed on the other two supporting ear plates 43 above the first bottom plate 1 or the second bottom plate 2 as needed, so that the upper surfaces of the first bottom plate 1 and the second bottom plate 2 connected side by side on the left and right can store longer logistics boxes, and the support plate 20 installed above can perform suspended storage and delivery of logistics boxes of other sizes.

[0042] Working principle:

[0043] When it is necessary to deliver a longer logistics box or a logistics item without a shell, the nut of the connecting bolt 44 is first removed, and then the bolt body of the connecting bolt 44 is pulled out from the two ends of the telescopic cross bar 5 and the bolt holes 431 opened on the support ear plates 43, so as to facilitate the removal of the telescopic cross bar 5 from the support ear plates 43 on the sides of the two square sleeves 42, and the second locking screw 78 is loosened to make the clamping plate 77 break away from the clamping fixation on the rotating sleeve 72, and then the tensioning screws 76 on the sides of the upper and lower connecting strips 71 are loosened to make the tensioning spring The spring 74 can be in a relaxed state, so that the rotating sleeve 72 can slide in the sliding guide groove 711, and then pull the second bottom plate 2 to make it away from the side of the first bottom plate 1, and then rotate the second bottom plate 2 180 degrees counterclockwise or clockwise as needed, so that when the left front end of the second bottom plate 2 rotates, the right front end of the first bottom plate 1 will not interfere, and then the supporting shaft on the second bottom plate 2 will rotate around the supporting shaft 6 on the first bottom plate 1 through the connecting strip 71 and the rotating sleeve 72, so that the first bottom plate 1 and the second bottom plate 2 can be adjusted side by side left and right. When the two logistics racks are arranged side by side, the upper and lower connecting strips 71 will be in a horizontal state, and then the logistics rack on the right will be pushed to make the second bottom plate 2 approach the first bottom plate 1, and the rotating sleeve 72 will contact the groove wall of the sliding guide groove 711, and then the tensioning screw 76 will be twisted so that the pushing block 75 pushes the tensioning spring 74 to compress, and then the limiting arc block 73 will limit and fix the rotating sleeve 72, and then the second locking screw 78 will be twisted so that the clamping plate 77 is pressed and fixed to the rotating sleeve 72, so that the first bottom plate 1 is placed on the The support shaft rod 6 and the support shaft rod 6 on the second bottom plate 2 are limited and fixed, so as to facilitate the limited and fixed two logistics racks connected side by side, and then the disassembled multiple telescopic cross bars 5 are installed on the front side of the first bottom plate 1 and the front and rear sides of the second bottom plate 2 which are symmetrical on the left and right sides, so as to facilitate blocking the vertical frames on both sides of the logistics rack after the length is adjusted, and prevent the logistics boxes or logistics items from falling off the logistics rack when longer logistics boxes or plate-shaped logistics items without shells are placed on the logistics rack after the length is adjusted.
