Description

Technical Field

[0001] This utility model relates to the field of logistics storage rack technology, specifically a modular warehouse rack for logistics supply. Background Technology

[0002] Storage racks are storage devices based on the six basic functions of logistics: packaging, transportation, loading and unloading, sorting, and information management. With the continuous development of the storage rack industry, more and more industries and enterprises are using storage racks, and more and more companies are entering the warehousing industry to serve friends from all walks of life. Shelves are one of the main facilities in warehousing. It can be said that shelves are an indispensable component of modern industrial warehouses, logistics centers, and distribution centers.

[0003] Patent CN111634595A proposes a modular storage rack for logistics supply. By rotating the winding reel on the side, the length of the pull rope can be controlled. The extension and retraction of the pull rope can drive the lower movable pulley group to move up and down. Since the movable pulley group has the characteristic of saving effort, the height adjustment can be made easier. Manual adjustment is easy, and it also reduces capital investment and saves energy, which is conducive to the widespread promotion and use of the equipment. When the appropriate height is reached, the movable rod at the bottom of the connecting seat can be pushed to lock and stabilize the operation, which makes the height of the equipment more stable and the use more stable.

[0004] The height of the storage rack can be adjusted by lifting, but this method is inconvenient for disassembly. Generally, it is difficult to remove the middle frame of a storage rack after installation, and it needs to be completely disassembled to remove it, which makes it inconvenient to use.

This utility model has a novel structure, in which multiple sets of splicing frames are connected to the base frame through screws and screw cylinders of locking components, splicing them into a whole. The telescopic rod on the back can improve the stability of the frame. The splicing frames can be disassembled from the middle without damaging the overall structure of the frame, making it convenient to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular storage rack for logistics supply, comprising a base frame, with multiple sets of splicing frames stacked on top of the base frame. Hollow grooves are formed on the four sides of the base frame and the splicing frames, and frame doors are installed on the front of the base frame and the splicing frames. Locking components are provided at the four corners of the splicing frames. Each locking component includes a first screw cylinder. Two first screw cylinders are slidably inserted into the top of one side of the splicing frame, and a first screw rod is threadedly inserted into the bottom of the first screw cylinder of the splicing frame.

[0007] Furthermore, the locking assembly also includes a fixing plate. The splicing frame is fixed at the top and bottom of the second screw and the second cylinder, and a connecting plate is installed at the outer end of the fixing plate. The second screw and the second cylinder are respectively fixed to the connecting plates at the top and bottom of the splicing frame.

[0008] Furthermore, a plug-in plate is fixed on the middle surface of the connecting plate, and a plug plate is fixed on the fixing plate at the position corresponding to the plug-in plate. The plug plate is slidably inserted into the plug-in plate.

[0009] Furthermore, a rotating groove is provided on the inner surface of the plug plate, and the plug plate can rotate within the rotating groove. A feed outlet is provided at the outer end of the plug plate, and the plug plate can be slidably pulled out from the feed outlet.

[0010] Furthermore, sponge pads are fixed on both sides of the connecting plate, and the sponge pads are pressed and contacted with the fixing plate.

[0011] Furthermore, at the four corners of the top of the bottom frame, corresponding to the positions of the first screw and the second screw, screws and bolts are respectively provided and locked to the splicing frame, and support feet are fixed at the four corners of the bottom of the bottom frame.

[0012] Furthermore, a base plate is fixed to the bottom of the back of the base frame, and telescopic rods are fixed to both ends of the base plate. An elastic clamp is sleeved on the surface of the telescopic rod corresponding to the first screw cylinder, and a locking bolt is inserted into the outer end of the elastic clamp.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a modular storage rack for logistics supply, including a base frame 1, with multiple sets of splicing frames 2 stacked on top of the base frame 1. Hollow grooves are formed on the four sides of the base frame 1 and the splicing frames 2, and frame doors 21 are installed on the front of the base frame 1 and the splicing frames 2. Locking components 3 are provided at the four corners of the splicing frames 2. Each locking component 3 includes a first screw cylinder 31. Two first screw cylinders 31 are slidably inserted into the top of one side of the splicing frame 2, and a first screw rod 32 is threadedly inserted into the bottom of the first screw cylinders 31 of the splicing frame 2. The top of the first screw rod 32 of the splicing frame 2 is in contact with the first screw cylinder 31. The first screw 32 of the adjacent splicing frame 2 is threadedly inserted into the first screw cylinder 31. Two sets of second screw cylinders 35 are provided on the bottom of the other side of the splicing frame 2, and two sets of second screws 37 are installed on the top of the splicing frame 2 on one side of the second screw cylinder 35. The second screws 37 of the adjacent splicing frame 2 are threadedly inserted into the second screw cylinder 35. When using the device, multiple sets of splicing frames 2 can be stacked and installed on the top of the bottom frame 1 as needed. The splicing frames 2 are locked and connected by the locking component 3. When it is necessary to remove a certain layer of splicing frame 2, the locking component 3 at that position is separated from the upper and lower sets of splicing frames 2, so that the splicing frame 2 can be removed separately without damaging the overall frame.

[0027] In this embodiment, the locking assembly 3 further includes a fixing plate 33. The top and bottom of the splicing frame 2 on one side of the second screw 37 and the second screw cylinder 35 are both fixed with fixing plates 33, and a connecting plate 34 is installed on the outer end of the fixing plate 33. The second screw 37 and the second screw cylinder 35 are respectively fixed to the connecting plates 34 at the top and bottom of the splicing frame 2. A connector plate 38 is fixed on the middle surface of the connecting plate 34, and a connector plate 310 is fixed to the fixing plate 33 at the position corresponding to the connector plate 38. The insert plate 310 is slidably inserted into the insert plate 38. A rotating groove 311 is formed on the inner surface of the insert plate 38, allowing the insert plate 310 to rotate within the groove. An outlet 39 is formed at the outer end of the insert plate 38, from which the insert plate 310 can be slidably pulled out. Sponge pads 36 are fixed to both sides of the connecting plate 34 on both sides of the insert plate 38, and the sponge pads 36 are in contact with the fixing plate 33. The first screw 32 of the upper splicing frame 2 is threaded into the lower splicing frame 2. Inside the first screw cylinder 31, the second screw cylinder 35 of the upper splicing frame 2 is sleeved on the second screw rod 37 of the lower splicing frame 2 to achieve the splicing and installation of the splicing frame 2. At this time, the insert plate 310 is inserted into the rotating groove 311 of the insert plate 38. When it is necessary to disassemble the middle splicing frame 2, the first screw rod 32 is first rotated upward to separate from the first screw cylinder 31 of the lower layer and retracted into the screw groove of the splicing frame 2. The first screw cylinder 31 of the splicing frame 2 is squeezed by the first screw rod 32 and moved upward by manual rotation to connect with the upper splicing frame. When the first screw 32 of frame 2 disengages from the splicing frame 2, one end of the splicing frame 2 is unrestricted and rotates in the opposite direction to the telescopic rod 51, rotating the splicing frame 2 180 degrees. At this time, the insert plate 310 corresponds to the outlet 39 and slides the splicing frame 2 outward. The fixing plate 33 of the splicing frame 2 separates from the connecting plate 34, while the connecting plate 34 is still locked and connected to the upper and lower sets of splicing frames 2 through the second screw 37 and the second screw cylinder 35, which makes it convenient to disassemble and remove the middle splicing frame 2 and to reassemble it later.

[0028] In this embodiment, screw cylinders and screw rods are respectively provided at the four corners of the top of the bottom frame 1, corresponding to the positions of the first screw rod 32 and the second screw cylinder 35, and are locked to the splicing frame 2. Support feet 4 are fixed at the four corners of the bottom of the bottom frame 1. The bottom frame 1 serves as the base for splicing and installation, with the support corners in contact with the ground. It does not have the structure on the splicing frame 2, but its top has screw cylinders and screw rods corresponding to the four corners of the splicing frame 2, which are connected and installed to the splicing frame 2.

[0029] In this embodiment, a base plate 5 is fixed to the bottom back of the base frame 1, and telescopic rods 51 are fixed to both ends of the base plate 5. An elastic clamp 53 is fitted onto the surface of the telescopic rod 51 corresponding to the surface of the first screw cylinder 31, and a locking bolt 54 is inserted into the outer end of the elastic clamp 53. The locking bolt 54 is in contact with the surface of the telescopic rod 51. A rotating plate 55 is fixed to the other side of the elastic clamp 53, and the first screw cylinder 31 is rotatably installed inside the rotating plate 55. A support plate 52 is installed on the telescopic rod 51 at the bottom position of each layer of splicing frame 2. The bottom of the splicing frame 2 is pressed into contact with the support plate 52, and both sides of the support plate 52 are slidably sleeved on the telescopic rod 51 and fixed by bolts. The telescopic rod 51 can be adjusted according to the height of the splicing frame 2. The first screw 31 of the splicing frame 2 is connected to the rotating plate 55 and is clamped to the surface of the telescopic rod 51 by the elastic clamp 53 to enhance the stability of the connection. The splicing frame 2 is supported by the cooperation of the two sets of telescopic plates and the support plate 52. The connection method adopted by the support plate 52 is similar to the connection method of the first screw 31 and the telescopic rod 51, and it can be slidably sleeved along the surface of the telescopic rod 51.

[0030] When using the device, multiple sets of splicing frames 2 are stacked and installed on top of the base frame 1 as needed. The splicing frames 2 are locked together by the locking assembly 3. When it is necessary to remove a certain layer of splicing frame 2, the first screw 32 of the upper splicing frame 2 is threaded into the first screw cylinder 31 of the lower splicing frame 2, and the second screw cylinder 35 of the upper splicing frame 2 is sleeved on the second screw 37 of the lower splicing frame 2 to achieve the splicing installation of the splicing frame 2. At this time, the insert plate 310 is inserted into the rotating groove 311 of the insert plate 38. When it is necessary to disassemble the middle splicing frame 2, the first screw 32 is first rotated upward to separate from the first screw cylinder 31 of the lower layer and retracted into the screw groove of the splicing frame 2. The first screw cylinder 31 of the splicing frame 2 is squeezed by the first screw 32 and moved upward by manual rotation to cooperate with the first screw 32 of the upper splicing frame 2 to disengage from the splicing. Frame 2, at this time, one end of the splicing frame 2 is unrestricted and rotates in the opposite direction to the telescopic rod 51, rotating the splicing frame 2 180 degrees. At this time, the insert plate 310 corresponds exactly to the delivery outlet 39, and the splicing frame 2 slides outward. The fixing plate 33 of the splicing frame 2 separates from the connecting plate 34, while the connecting plate 34 is still locked and connected to the upper and lower sets of splicing frames 2 through the second screw 37 and the second screw cylinder 35, which makes it convenient to disassemble and remove the middle splicing frame 2 and to reassemble it later. It slides onto the telescopic rod 51 and is fixed by bolts. The telescopic rod 51 can be adjusted according to the height of the splicing frame 2. The first screw cylinder 31 of the splicing frame 2 is connected to the rotating plate 55 and is clamped to the surface of the telescopic rod 51 by the elastic clamp 53 to enhance the stability of the connection. The splicing frame 2 is supported by the cooperation of the two sets of telescopic plates and the support plate 52.
