[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0023] Please refer to Figures 1-6 , an embodiment provided by the present utility model:
[0024] A beam - type shelf that is easy to assemble: It includes a column 1, a mounting block 11 is inserted on the surface of the column 1, a cross - beam body 12 is fixedly connected to the surface of the mounting block 11, a first limiting tube 2 is fixedly connected to the surface of the column 1, a spring 21 is in contact connection with the surface of the column 1, a movable block 24 is slidably connected to the surface of the column 1, a second limiting tube 25 is fixedly connected to the lower surface of the movable block 24, a clamping block 26 is fixedly connected to the upper surface of the movable block 24, a movable disc 22 is slidably connected to the inner surface of the second limiting tube 25, and a pressing piece 23 is fixedly connected to the surface of the movable disc 22. This beam - type shelf can replace the spring 21 on the column 1, so that the spring 21 can have sufficient elastic force to limit the cross - beam body 12 on the column 1, thereby ensuring the stability between the column 1 and the cross - beam body 12.
[0025] Furthermore, a support mechanism is provided at the bottom of the column 1. The support mechanism includes a rotating rod 3 which is rotatably connected to the surface of the column 1. A support rod 31 is fixedly connected to the surface of the rotating rod 3, and a support block 32 is fixedly connected to the surface of the support rod 31. A nut 33 is fixedly connected to the surface of the column 1, and a screw rod 34 is threadedly connected to the surface of the nut 33. During the assembly process of the column 1 and the crossbeam body 12, it is necessary to support the column 1. This support mechanism can support the column 1 during the assembly process of the column 1 and the crossbeam body 12, eliminating the need for manual support of the column 1 and making it more convenient for the assembler to carry out the assembly process.
[0026] Furthermore, a card slot is provided on the surface of the column 1, and the mounting block 11 is inserted into the card slot of the column 1. The column 1 supports the crossbeam body 12 through the mounting block 11. After inserting the mounting block 11 into the card slot of the column 1, the position of the mounting block 11 on the column 1 is fixed. A guiding groove is provided below the card slot of the column 1, and the movable block 24 slides on the guiding groove of the column 1. During the sliding process of the movable block 24, the second limiting tube 25 and the clamping block 26 are driven to slide simultaneously. During the descending process of the second limiting tube 25, the spring 21 is squeezed through the movable disk 22 and the pressing piece 23, causing the spring 21 to be deformed by extrusion.
[0027] Furthermore, a connection hole is provided on the surface of the column 1. The connection hole of the column 1 communicates with the card slot and the guiding groove of the column 1. The clamping block 26 slides on the connection hole of the column 1. The top of the clamping block 26 is beveled. When the bevel surface of the clamping block 26 is squeezed, the clamping block 26 slides downward on the connection hole of the column 1, facilitating the installation of the mounting block 11 on the column 1. A card slot is provided on the lower surface of the mounting block 11, and the clamping block 26 is snap-connected to the card slot of the mounting block 11.
[0028] Furthermore, the first limiting tube 2 restricts the position of the bottom of the spring 21, and the second limiting tube 25 restricts the position of the top of the spring 21, preventing the spring 21 from falling off the guiding groove of the column 1. Guide grooves are provided on both sides of the second limiting tube 25, and the pressing piece 23 slides on the guide grooves of the second limiting tube 25. The top of the spring 21 is in contact connection with the movable disk 22. By operating the pressing piece 23, the movable disk 22 can be made to slide downward independently on the second limiting tube 25. At this time, the spring 21 is squeezed by the movable disk 22, so that the movable block 24, the second limiting tube 25 and the clamping block 26 slide out of the column 1, and then the spring 21, the movable disk 22 and the pressing piece 23 are removed, completing the disassembly of the spring 21 and facilitating the replacement of the spring 21.
[0029] Furthermore, a storage groove is formed at the bottom of the column 1. The support rod 31 rotates at the bottom of the column 1 through the rotating rod 3, and the support block 32 rotates synchronously with the support rod 31 on the column 1. The support block 32 supports one end of the support rod 31 away from the column 1 on the ground. The support rod 31 and the support block 32 can be rotated onto the storage groove of the column 1, thus not occupying space.
[0030] Furthermore, a circular hole is formed at the bottom of the column 1. The screw rod 34 passes through the circular hole of the column 1 and is threadedly connected with the nut 33. The screw rod 34 restricts the angle of the support rod 31 on the column 1. The support rod 31 can only rotate 90 degrees on the column 1. The screw rod 34 can only limit the position of the support rod 31 when the support rod 31 is in a parallel or perpendicular state. When the support rod 31 and the column 1 are perpendicular to each other, the support rod 31 can support the column 1, avoiding the need for an assembler to hold it during the assembly task.
[0031] Working principle: By sliding the pressing piece 23 downward along the guiding groove of the second limiting tube 25, the pressing piece 23 drives the movable disk 22 to slide downward on the inner surface of the second limiting tube 25. At this time, the clamping block 26 is slid out of the connecting hole of the column 1 through the movable block 24. Then, the movable disk 22 and the pressing piece 23 are completely separated from the second limiting tube 25. At this time, the movable block 24, the second limiting tube 25, and the clamping block 26 can be removed from the column 1, and the movable disk 22 and the pressing piece 23 can also be removed from the spring 21. Finally, the spring 21 is taken out of the first limiting tube 2, which facilitates the removal of the spring 21, and further facilitates the replacement of the spring 21, enabling the spring 21 to have sufficient elasticity to limit the crossbeam body 12 on the column 1, thereby ensuring the stability between the column 1 and the crossbeam body 12.
[0032] Rotate the support rod 31 on the column 1 through the rotating rod 3 so that the support rod 31 rotates on the column 1 to be perpendicular to the column 1. At this time, the support block 32 supports one side of the support rod 31 away from the column 1 on the ground. Pass the screw rod 34 through the circular hole of the column 1 and thread the screw rod 34 onto the nut 33. The screw rod 34 restricts the perpendicular relationship between the support rod 31 and the column 1. The support block 32 and the support block 32 support the column 1, enabling the column 1 to be supported without the need for manual assistance, which facilitates the assembler to assemble the column 1 and the crossbeam body 12.
[0033] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
