Description

Technical Field

[0001] This utility model relates to the field of square tube processing technology, specifically a rectangular tube fixing structure. Background Technology

[0002] A rectangular tube is a hollow tube with a rectangular cross-section. Its four sides are parallel to each other and adjacent sides are perpendicular to each other, forming a regular rectangular outline. It is widely used in industries such as industry, construction, and machinery manufacturing. A rectangular tube fixing mechanism is a device or system used to clamp and position rectangular tubes (including square tubes) to keep them stable in industrial production, construction and other scenarios.

[0003] However, existing technologies still have the following problems:

[0004] Traditional methods of fixing rectangular tubes often involve simple bolt fastening or single clamping, which results in unstable fixing and difficulty in adapting to rectangular tubes of different sizes. In addition, existing fixing devices are usually fixed in position and height after installation, making it difficult to flexibly cope with different height operation scenarios. When moving the equipment, it is necessary to rely on hoisting or multiple people to carry it, which is cumbersome and inefficient. Utility Model Content

[0005] To address the problems of rectangular tubes being difficult to fix and unable to adjust their fixed height, the purpose of this utility model is to provide a rectangular tube fixing structure.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a rectangular tube fixing structure, including a support platform, a fixing device symmetrically fixedly connected to the upper surface of the support platform, a lifting mechanism provided on the lower surface of the support platform, the fixing device including a base, guide columns symmetrically fixedly installed on the upper surface of the base, a support plate fixedly connected to the top ends of the two guide columns, a threaded rod threaded into the outer surface of the support plate, a knob fixedly connected to the top end of the threaded rod, the bottom end of the knob penetrating the support plate and fixedly connected to a fixing block, and fixing grooves provided on the upper surface of the base and the lower surface of the fixing block, the two fixing grooves cooperating for use.

[0007] Preferably, the lifting mechanism includes a bracket, with telescopic columns symmetrically fixedly connected to both sides of the bracket. The top of each telescopic column is fixedly connected to the lower surface of the support platform. A bidirectional lead screw is rotatably connected to the upper surface of the bracket. A handwheel is fixedly connected to one end of the bidirectional lead screw. Moving parts are symmetrically threaded onto the outer surface of the bidirectional lead screw. Lifting connecting rods are symmetrically rotatably connected to the outer surfaces of the two moving parts. The upper end of each lifting connecting rod is rotatably connected to the lower surface of the support platform.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] This utility model, through the setting of a fixing device and a lifting mechanism, features a 90-degree V-shaped fixing groove with anti-slip texture, which can tightly clamp the rectangular tube from both the top and bottom. The V-shaped groove is precisely aligned, and the anti-slip texture increases friction, ensuring the rectangular tube is firmly fixed and preventing slippage. At the same time, the center points of the two fixing devices are on the same straight line, ensuring balanced force and improving the reliability of the fixation. The lifting mechanism on the lower surface of the support platform utilizes the linkage of a two-way lead screw, a moving kit, and a lifting linkage. Turning the handwheel can realize the vertical lifting of the support platform, which can flexibly adapt to different height operation requirements and enhance the versatility of the equipment. Furthermore, the base of the fixing device is bolted to the mounting holes of the support platform to accommodate building pipes of different lengths. The bottom of the lifting mechanism is equipped with casters for easy movement of the equipment. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Figure 1-3As shown, this utility model provides a rectangular tube fixing structure. A support platform 11 serves as the basic component, supporting the overall structure and the rectangular tube. A fixing device 12, consisting of a base 14, is symmetrically fixedly connected to its upper surface. The base 14 is fixed to the support platform 11 by bolts through multiple mounting holes 10 on its upper surface, ensuring structural stability. Operators can install and disassemble the fixing device 12 through the mounting holes 10, and the distance between the two fixing devices 12 can be easily adjusted to accommodate square tubes of different lengths.

[0017] Guide pillars 15 are symmetrically fixedly installed on the upper surface of the base 14. The top ends of the two guide pillars 15 are fixedly connected to a support plate 16, forming a frame to provide guidance and support for the threaded rod 17. The threaded rod 17 is threaded into the outer surface of the support plate 16. A knob 18 is fixedly connected to the top end of the threaded rod 17. The bottom end of the knob 18 passes through the support plate 16 and is fixedly connected to a fixing block 19. The outer surfaces of the two sides of the fixing block 19 slide against the outer surfaces of the two guide pillars 15. When the knob 18 is rotated, the threaded rod 17 drives the fixing block 19 to move up and down along the guide pillars 15. The upper surface of the base 14 and the lower surface of the fixing block 19 are both provided with 90-degree V-shaped fixing grooves 20, and the two fixing grooves 20 are located on the same vertical horizontal line. The outer surface of the fixing groove 20 located at the lower end of the fixing block 19 is symmetrically provided with anti-slip textures, which can tightly clamp the rectangular tube from the top and bottom. The V-shaped groove can accurately center the rectangular tube, and the anti-slip textures increase friction to prevent slippage. The center points of the two fixing devices 12 are located on the same straight line to ensure balanced force.

[0018] The lower surface of the support platform 11 is provided with a lifting mechanism 13 consisting of a bracket 21. Telescopic columns 22 are symmetrically fixedly connected on both sides of the bracket 21, and their tops are connected to the lower surface of the support platform 11, which serves as a guide and initial support. The bottom ends of the two telescopic columns 22 on the same side are fixedly connected to a base plate 27. Universal wheels are symmetrically installed on the lower surface of the base plate 27 to facilitate the overall movement of the equipment.

[0019] A bidirectional lead screw 23 is rotatably connected to the upper surface of the bracket 21, with a handwheel 24 fixedly connected to one end. The outer surface of the bidirectional lead screw 23 is symmetrically threaded with moving parts 25. The outer surfaces of the two moving parts 25 are symmetrically rotatably connected to lifting rods 26. The upper end of the lifting rod 26 is rotatably connected to the lower surface of the support platform 11. When the handwheel 24 is turned, the bidirectional lead screw 23 rotates, driving the moving parts 25 on both sides to move synchronously in opposite directions, thus driving the lifting rods 26 in conjunction, achieving vertical lifting of the support platform 11. This meets the needs of different height operations, allowing the fixed structure to adapt to various working conditions.

[0020] Working principle: When this rectangular tube fixing structure is in operation, the support platform 11 serves as the core load-bearing foundation. The upper surface fixing device 12 operates as follows: the base 14 is fixed by bolts precisely fitting into the mounting holes 10 of the support platform 11. Two guide columns 15 are vertically mounted on the base 14, with the top connected to the support plate 16, together forming a stable "gantry"-style frame structure. The operator manually rotates the knob 18. Because the threaded rod 17 is threadedly engaged with the support plate 16, when the threaded rod 17 rotates, it moves downwards along its own axis, thereby driving the bottom fixing block 19 to move vertically up and down along the guide columns 15. When the rectangular tube is placed into the fixing groove 20 opened in the base 14, the fixing groove 20 is 90-degree V-shaped and the groove surface has anti-slip texture, which can automatically center and initially limit the rectangular tube. As the fixing block 19 continues to descend, the same 90-degree V-shaped fixing groove 20 on its lower surface will fit against the upper surface of the rectangular tube. Relying on the squeezing force of the V-shaped groove and the increased friction of the anti-slip texture, the rectangular tube is firmly clamped from the top and bottom, restricting the displacement of the rectangular tube in the vertical and horizontal directions, and achieving stable clamping and fixing.

[0021] When the support height needs to be adjusted, the bracket 21, as a basic support component, is connected to the lower surface of the support platform 11 via the telescopic column 22, providing vertical guidance and support for the support platform 11. The operator turns the handwheel 24, which drives the bidirectional lead screw 23 to rotate on the bracket 21. Due to its bidirectional thread design, the bidirectional lead screw 23 drives two moving components 25 mounted on it to move synchronously in opposite directions, either moving closer or further apart. The lifting linkage 26 is rotatably connected at both ends to the moving components 25 and the lower surface of the support platform 11, forming a scissor-type linkage mechanism. When the moving components 25 move, the lifting linkage 26 moves accordingly, pushing the support platform 11 to achieve vertical lifting along the telescopic column 22. Simultaneously, the base plate 27 with casters connected to the bottom of the telescopic column 22 allows for flexible repositioning when the equipment needs to be moved, meeting the requirements for height adjustment and equipment movement during rectangular tube fixing, ensuring adaptability and flexibility for rectangular tube fixing operations.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
