The present invention has the effect of facilitating disassembly and assembly and improving disassembly and assembly efficiency.

[0005] However, in the above technical solution, the shelves are not very convenient to install, especially when individual shelf units are spliced ​​and installed into an integral shelf, it is rather troublesome. In addition, in order to ensure the stability of the structure, the existing shelves usually require certain mechanical parts to be installed during splicing and installation, which makes it very troublesome to disassemble. If mechanical rigid connection is not used for installation, the stability will be affected to a certain extent, so the overall structure is not ideal.

[0006] Therefore, in order to solve the above problems, it is necessary to develop a storage shelf with a reasonable structure and convenient assembly and disassembly. Summary of the invention

[0007] The purpose of the present invention is to provide a storage shelf that is easy to assemble and disassemble in view of the shortcomings of the prior art; the technical solution is as follows:

[0008] A storage shelf that is easy to assemble and disassemble, comprising a plurality of shelf units, each of which comprises columns on both sides and a detachable shelf board installed between the columns on both sides; and the inner side walls of the columns are also provided with mounting grooves that are evenly distributed from top to bottom, and a downward pressure spring is correspondingly provided in the mounting groove, and a triangular pressure block is installed at the lower end of the downward pressure spring; and the two side ends of the shelf board are correspondingly provided with oblique pressure edges, and the two ends of the shelf board are correspondingly placed behind the mounting grooves, and the triangular pressure blocks above are correspondingly pressed on the oblique pressure edges of the two side ends of the shelf board, so that the shelf board is fixed between the columns on both sides;

[0009] A corresponding splicing groove is also provided at the outer side wall of each column, and adjacent shelf units are spliced ​​and installed correspondingly through the splicing grooves on adjacent columns to form an integral logistics shelf.

[0010] Furthermore, the splicing groove on the column is set to a trapezoidal structure, and the width of the slot of the splicing groove is set to be smaller than the width of the slot bottom; when two columns are spliced ​​correspondingly, the positions of the splicing grooves on the columns correspond, and an integral groove is formed after splicing, and the upper and lower ends of the integral groove are V-shaped, and the left and right ends are vertical surfaces;

[0011] It also includes a card block unit, which includes V-shaped plates on the upper and lower sides, panels on the front and rear sides, and vertical plates on the left and right sides. The card block units are placed in the overall grooves accordingly, and the V-shaped plates on the upper and lower sides are correspondingly clamped in the upper and lower ends of the overall grooves, and then the two splicing grooves are clamped in the left and right directions, so that the columns on both sides are spliced ​​into one in the left and right directions.

[0012] Furthermore, the positions of the vertical plates on the left and right sides of the card block unit and the vertical surface of the overall groove do not correspond; the length of the upper and lower V-shaped plates is set to half the length of the upper and lower trapezoidal sides of the splicing groove; so that the vertical plates are also set at half the position of the trapezoidal groove, and the outer half of the trapezoidal groove is set as the expansion area;

[0013] Expansion bodies are correspondingly installed on the vertical plates on the left and right sides of the card block unit, and the expansion bodies are correspondingly connected to the internal space of the card block unit, so that the card block unit and the space inside the expansion bodies on the left and right sides form a closed space, and an inflation valve is also provided on the front panel. The expansion body is located in the expansion area of ​​the trapezoidal groove, and the inflation valve is externally connected to an inflation device. After the card block unit is inflated by the inflation device, the expansion bodies on both sides gradually expand, so that the expansion bodies are correspondingly pressed against the side walls of the groove body of the splicing groove, thereby fixing the card block unit in the splicing groove.

DETAILED DESCRIPTION

[0037] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0038] like Figure 1 As shown, a storage shelf that is easy to assemble and disassemble includes several shelf units, each of which includes columns 1 on both sides and a detachable shelf board 2 installed between the columns 1 on both sides; and the inner side wall position of the column 1 is also provided with mounting grooves 3 evenly distributed from top to bottom, and a downward pressure spring 4 is correspondingly provided in the mounting groove 3, and a triangular pressure block 5 is installed at the lower end of the downward pressure spring 4; and the two side ends of the shelf board 2 are correspondingly provided with oblique pressure edges 6, and the two ends of the shelf board 2 are correspondingly placed after the mounting groove 3, and the triangular pressure blocks 5 above are correspondingly pressed on the oblique pressure edges 6 on the two side ends of the shelf board 2, so as to fix the shelf board 2 between the columns 1 on both sides;

[0039] like Figure 2 As shown, a corresponding splicing groove 7 is also provided at the outer side wall of each column 1, and adjacent shelf units are spliced ​​and installed correspondingly through the splicing grooves 7 on adjacent columns 1, thereby forming an integral logistics shelf.

[0040] The splicing groove 7 on the column 1 is set to a trapezoidal structure, and the slot width of the splicing groove 7 is set to be smaller than the slot bottom width; when two columns 1 are spliced ​​correspondingly, the positions of the splicing grooves 7 on the columns 1 correspond, and after splicing, an integral groove 8 is formed, and the upper and lower ends of the integral groove 8 are V-shaped, and the left and right ends are vertical surfaces;

[0041] like Figure 3 As shown, it also includes a block unit 9, which includes V-shaped plates 10 on the upper and lower sides, panels 11 on the front and rear sides, and vertical plates 12 on the left and right sides. The block unit 9 is placed in the overall groove 8 accordingly, and the upper and lower V-shaped plates 10 are correspondingly clamped in the upper and lower ends of the overall groove 8, and then the two splicing grooves 7 are clamped in the left and right directions, so that the columns 1 on both sides are spliced ​​into one in the left and right directions.

[0042] like Figure 4 As shown, the vertical plates 12 on the left and right sides of the card block unit 9 do not correspond to the positions of the vertical surface of the integral groove 8; the length of the upper and lower V-shaped plates 10 is set to half the length of the upper and lower trapezoidal sides of the splicing groove 7; so that the vertical plates 12 are also correspondingly set at the half position of the trapezoidal groove, and the outer half of the trapezoidal groove is correspondingly set as the expansion area 15;

[0043] An expansion body 13 is also installed correspondingly on the vertical plates 12 on the left and right sides of the block unit 9. The expansion body 13 is correspondingly connected to the internal space of the block unit 9, so that the block unit 9 and the space inside the expansion bodies 13 on the left and right sides form a closed space, and an inflation valve 14 is also provided on the front panel 11. The expansion body 13 is located in the expansion area 15 of the trapezoidal groove. The inflation valve 14 is externally connected to an inflation device. After the block unit 9 is inflated by the inflation device, the expansion bodies 13 on both sides gradually expand, so that the expansion bodies 13 are correspondingly pressed against the side walls of the splicing groove 7, thereby fixing the block unit 9 in the splicing groove 7.

[0044] like Figure 5 and Figure 6 As shown, the splicing groove 7 is further provided with an arc-shaped through hole 16 at the position of the trapezoidal sides on the upper and lower sides. The positions of the splicing grooves 7 on the two adjacent columns 1 correspond, so that the positions of the arc-shaped through holes 16 on the two splicing grooves 7 also correspond relatively, and a splicing tube 17 is installed in the arc-shaped through hole 16 on one side, and a splicing rod 18 is correspondingly installed in the arc-shaped through hole 16 on the other side. The splicing tube 17 and the splicing rod 18 are both arc-shaped structures and can move correspondingly in the arc-shaped through hole 16. The inner ends of the splicing tube 17 and the splicing rod 18 are correspondingly arranged in the arc-shaped through hole 16, and the outer ends of the splicing tube 17 and the splicing rod 18 extend into the expansion area 15 of the splicing groove 7, corresponding to the position of the expansion body 13;

[0045] like Figure 7 and Figure 8As shown, the inner diameter of the splicing tube 17 is matched with the outer diameter of the splicing rod 18. When the expansion body 13 is inflated, the splicing rod 18 and the splicing tube 17 are squeezed toward both sides, causing the splicing tube 17 and the splicing rod 18 in the arc-shaped through holes 16 on both sides to enter into the arc-shaped through holes 16 on the other side. Correspondingly, the splicing rod 18 enters into the adjacent splicing tube 17, so that the two columns 1 generate limiting forces in the left-right direction and the front-back direction, splicing and fixing the two columns 1 together.

[0046] The angles of the upper and lower trapezoidal sides of the splicing groove 7 are set to 45°, the length of the single arc-shaped through hole 16 is set to 1 / 8 of the circumference, and the lengths of the splicing tube 17 and the splicing rod 18 are set to 1 / 4 of the circumference; when the splicing tube 17 and the splicing rod 18 are placed in the arc-shaped through hole 16, half of the length is located in the arc-shaped through hole 16, and the other half of the length is located in the expansion area 15;

[0047] like Fig.10 As shown, the expansion body 13 is located between the upper and lower splicing tubes 17 or splicing rods 18. When the expansion body 13 expands, the splicing tube 17 or the splicing rod 18 is squeezed as a whole into the arc-shaped through hole 16, so that the splicing tube 17 and the splicing rod 18 form a completely overlapping state in the arc-shaped through hole 16.

[0048] like Fig. 9 As shown, each arc-shaped through hole 16 is also provided with a limiting groove 19, and the splicing tube 17 and the splicing rod 18 are provided with a limiting block 20 corresponding to the position of the limiting groove 19, the limiting block 20 is correspondingly embedded in the limiting groove 19, and a return spring 21 is also installed in the limiting groove 19; when the expansion body 13 expands, the splicing tube 17 and the splicing rod 18 are pressed, so that the limiting block 20 moves in the limiting groove 19, and then presses the return spring 21; and when the expansion body 13 is deflated, the splicing tube 17 and the splicing rod 18 are reset under the action of the return spring 21, and the outer ends of the splicing tube 17 and the splicing rod 18 are correspondingly reset to the expansion area 15.

[0049] The front and rear ends of the integral groove 8 are also provided with packaging plates, and the block unit 9 and the expansion body 13 are correspondingly packaged in the integral groove 8 through the packaging plates.

[0050] The specific working principle of the present invention is as follows: Figure 1 As shown, the overall shelf of the present invention is composed of a plurality of shelf units. A single shelf unit includes columns and shelf boards on both sides, and the shelf boards are designed to be easily disassembled. During installation, the oblique pressure edges on both sides of the shelf boards are pressed by the triangular pressure blocks above through the downward pressure springs. Therefore, the shelf boards are not rigidly installed structures, but are pressed by downward pressure springs. The disassembly of the shelf boards themselves is very convenient, and the size of the storage space can be adjusted conveniently.

[0051] At the same time, the overall shelf is installed by docking the shelf units, and the specific docking installation is completed through the columns on both sides. The two adjacent shelf units can be docked through the splicing grooves on the columns. The splicing grooves on the columns are designed to be trapezoidal groove structures. The groove size is small and is laterally set outward. When the two columns are placed together, the positions of the splicing grooves on both sides are also corresponding. Since the two splicing grooves are trapezoidal, the upper and lower ends of the overall groove after splicing form a V-shaped groove; then it is only necessary to set the upper and lower side plates of the card block unit to V-shaped plates of a V-shaped structure, and then install the card block unit in the overall groove, so that the columns on both sides can be connected and spliced ​​together, and the two columns will not be separated in the left and right directions.

[0052] However, the above structure only limits the columns on both sides in the left and right directions, and the card block unit itself is not restricted in the overall groove, and it is also possible to fall due to vibration and other reasons. Therefore, the present invention also arranges expansion bodies on the vertical plates on the left and right sides of the card block unit. First, the upper and lower V-shaped plates of the card block unit are not set to be consistent with the upper and lower V-shaped side walls of the overall groove. The length is only set to half, so the vertical plate is located at half of the splicing groove, and the other half is used to place the expansion body, which is also called the expansion area. The purpose of this design is that when the expansion body expands, the expansion body will be directly squeezed on the side wall of the expansion area of ​​the splicing groove, and the expansion body is connected to the card block unit as a whole. After this design, the card block unit is fixed in the splicing groove. Whether it is shaking or for other reasons, the card block unit will not fall easily. Moreover, this method is not installed through mechanical rigidity. The card block unit can be removed by simply deflation, which is very convenient.

[0053] However, the above design can only ensure the limiting force of the two columns in the left and right directions, and the two columns can still move greatly in the front and rear directions. Therefore, the present invention sets arc-shaped through holes at the upper and lower positions of the splicing grooves, and the positions of the arc-shaped through holes in the splicing grooves on the columns on both sides are corresponding and can be interconnected. Then, a splicing tube is installed in the arc-shaped through hole on one side, and a splicing rod is installed in the arc-shaped through hole on the other side. The setting here requires that the tail ends of the splicing tube and the splicing rod extend from the arc-shaped through hole into the expansion area and are located at the outer side of the expansion body, and the front ends of the splicing tube and the splicing rod are located in the arc-shaped through hole. When the expansion body is about to expand, the expansion body will press on the side wall of the splicing groove on the one hand, and on the other hand, it will press and urge the splicing tube and the splicing rod to move into the arc-shaped through hole, so that the splicing rod is inserted into the splicing tube and both enter the arc-shaped through hole on the other side. After this design, the two columns are restricted in the front and rear directions by the splicing tube and the splicing rod that are connected as one, and will not move in the front and rear directions; and because the splicing tube and the splicing rod are both arc-shaped structures, after the two are docked and inserted, and after they enter into adjacent arc-shaped through holes, they will also be restricted in the left and right directions, making the splicing structure of the two columns more stable.

[0054] The present invention also specifically limits the angle of the trapezoidal side of the splicing groove, which can be specifically set to 45°. After such a design, the length of the arc-shaped through hole is 1 / 8 of the circumference, and the splicing tube and the splicing rod are set to 1 / 4 of the circumference. Half of the splicing tube and the splicing rod are in the arc-shaped through hole, and half are in the expansion area. When the expansion body is inflated and compressed, the splicing tubes and splicing grooves on both sides can overlap in the arc-shaped through hole, and the structure is more stable and reliable.

[0055] In addition, the present invention also provides a limit groove on the arc through hole and a limit block on the splicing tube and the splicing rod. The limit block is embedded in the limit groove and a corresponding reset spring is installed. The purpose of this design is that when the expansion body is deflated through the inflation valve, the splicing tube and the splicing rod will be directly reset under the action of the reset spring, which will not affect the next use. The disassembly of the present invention after splicing is very convenient. It only needs to deflate the expansion body, the block unit can be easily taken out, and the splicing tube and the splicing rod are also reset accordingly, which is very convenient.

[0056] The above specific implementation is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention and the scope of the claims. All equivalent changes and modifications made according to the content of the patent protection scope of the present invention should be included in the scope of the patent application of the present invention.
