Description

Technical Field

[0001] This utility model relates to the field of architectural decoration or display props technology, specifically a modular square column component. Background Technology

[0002] Square column components are widely used as supporting, dividing, or decorative structures in fields such as building decoration (e.g., shop columns, interior partitions), exhibition displays (e.g., temporary booth columns), furniture manufacturing (e.g., cabinet support columns), and landscape facilities (e.g., park decorative columns).

[0003] Existing square columns are mostly integrally molded structures, which occupy a lot of space during transportation, are prone to increasing logistics costs due to exceeding size limits, and are easily damaged by collisions during long-distance transportation. In addition, some assembled square columns use a single bolt connection, which requires repeated alignment of holes during installation, resulting in low efficiency. Furthermore, the bolts are prone to loosening after long-term use, leading to poor overall stability of the square column. Therefore, those skilled in the art have provided an assembled square column assembly to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a modular square column assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A modular square column assembly includes a square column body, which is a hollow square tubular structure with a square cross-section. The bottom surface of the square column body has a tenon groove, and the inner wall of the tenon groove has two guide grooves. A tenon is connected to the upper surface of the square column body, and guide strips are connected to both the front and back of the tenon. The inner wall of the tenon groove has a first threaded hole, and the inside of the tenon has a second threaded hole.

[0006] As a further improvement of this utility model: a sealing plug is provided inside the first threaded hole, and a knob is connected to the right side of the sealing plug.

[0007] As a further improvement of this utility model: the outer diameter of the tenon and the inner diameter of the mortise are in clearance fit, and the height of the tenon is equal to the depth of the mortise.

[0008] As a further embodiment of this utility model: the square column body is integrally extruded from aluminum alloy profile or ABS engineering plastic, and the outer surface of the square column body is coated with polyfluorocarbon coating or electrostatic powder coating.

[0009] As a further improvement of this utility model: the inner wall of the square column body is connected with two sets of equally spaced reinforcing ribs, each of which is integrally formed with the square column body.

[0010] As a further improvement of this utility model: the inner sidewall of the square column body is provided with two sets of weight-reducing holes arranged at equal intervals, and each weight-reducing hole is a circular hole.

[0011] As a further improvement of this utility model: the bottom surface of the square column body is provided with two sets of positioning holes, and the upper surface of the square column body is connected with two sets of positioning pins.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This modular square column assembly features a foolproof structure formed by the cooperation of guide strips and guide grooves, which can prevent misalignment of tenons during assembly. Even non-professionals can operate it quickly. Compared with traditional welding or bolt connections, it can greatly improve the assembly efficiency of the square column body. At the same time, the surface contact force of the tenon and mortise connection plus the point locking of the threaded fastening double fixation can improve the pull-out force and shear force at the assembly point of the two square column bodies. Compared with a single tenon and mortise connection, it can improve the structural stability of the square column body. Attached Figure Description

[0015] Please see Figures 1-4 In this embodiment of the utility model, a modular square column assembly includes a square column body 1, which is a hollow square tubular structure with a square cross-section. A tenon 2 is formed on the bottom surface of the square column body 1, and two guide grooves 3 are formed on the inner wall of the tenon 2. A tenon 4 is connected to the upper surface of the square column body 1, and guide strips 5 are connected to both the front and back of the tenon 4. A first threaded hole 6 is formed on the inner wall of the tenon 2, and a second threaded hole 7 is formed inside the tenon 4. The anti-misalignment structure formed by the guide grooves 3 and guide strips 5 prevents misalignment of the tenon 4 during assembly, thus greatly improving the assembly efficiency of the square column body 1. Simultaneously, the point locking and fixing effect formed by the first threaded hole 6, the second threaded hole 7, and the external threaded rod greatly improves the pull-out and shear resistance of the assembled square column body 1.

[0016] The first threaded hole 6 is equipped with a sealing plug 8 inside. A knob 9 is connected to the right side of the sealing plug 8. The outer diameter of the tenon 4 and the inner diameter of the mortise 2 are in clearance fit. The height of the tenon 4 is equal to the depth of the mortise 2. The square column body 1 is integrally extruded from aluminum alloy profile or ABS engineering plastic. The outer surface of the square column body 1 is coated with a fluorocarbon coating or an electrostatic powder coating. The removable design of the sealing plug 8 protects the threaded hole from impurities without affecting subsequent disassembly and adjustment. Through the clearance fit between the tenon 4 and the mortise 2 and the matching design of height and depth, the coaxiality error after the upper and lower columns are connected can be reduced. Through the fluorocarbon coating or electrostatic powder coating on the outer surface of the square column body 1, the weather resistance of the square column body 1 can be increased, thereby extending the service life of the component and reducing the later replacement cost.

[0017] The inner wall of the square column body 1 is connected to two sets of equally spaced reinforcing ribs 12, each reinforcing rib 12 being integrally formed with the square column body 1. The inner side wall of the square column body 1 is provided with two sets of equally spaced weight-reducing holes 13, each weight-reducing hole 13 being a circular hole. The bottom surface of the square column body 1 is provided with two sets of positioning holes 10, and the upper surface of the square column body 1 is connected with two sets of positioning pins 11. Through the combination of the hollow structure and the reinforcing ribs 12, not only can the weight of the square column body 1 be reduced, but also the bending strength of the square column body 1 can be increased, thereby preventing the square column body 1 from bending and deforming during long-term use. The weight-reducing holes 13 can further reduce the weight of the square column body 1, which can not only reduce transportation costs, but also eliminate the need for heavy equipment during installation, allowing a single person to handle and assemble it. Through the pre-positioning design of the positioning pins 11 and the positioning holes 10, repeated manual calibration can be avoided, thereby indirectly improving the assembly efficiency of the two square column bodies 1.

[0018] The working principle of this utility model is as follows: When assembling this device, the initial alignment is achieved first through the positioning pin 11 and positioning hole 10, so that the positioning hole 10 on the bottom surface of the upper square column body 1 and the positioning pin 11 on the upper surface of the lower square column body 1 are precisely engaged, quickly eliminating the horizontal offset error. Then, the tenon 4 of the upper square column body 1 is aligned with the mortise 2 of the lower square column body 1 and inserted. At this time, the guide strips 5 on the front and back of the tenon 4 slide along the guide groove 3 on the inner side wall of the mortise 2, forcibly restraining the tilt of the square column body 1 during the vertical assembly process, ensuring that the tenon 4 and the mortise 2 are completely fitted. After the connection is completed, the fastener is inserted through the first threaded hole 6 on the side of the square column body 1 and threadedly connected to the second threaded hole 7 inside the tenon 4, rigidly locking the upper and lower square column bodies 1 to prevent loosening after assembly. The above is the assembly process of this device.
