Description

A base connector with adjustable pipe overlap angle Technical Field

[0001] This utility model relates to the technical field of supplies for connecting steel pipe frames, and specifically to a base connector that can change the overlapping angle of pipe fittings. Background Technology

[0002] In modern industrial production, steel pipe frames are widely used in various fields such as machinery manufacturing, construction engineering, and furniture manufacturing due to their high strength, light weight, ease of processing and disassembly. A steel pipe frame is a support structure composed of multiple steel pipes connected by frame connectors.

[0003] Among them, the base connector, as a connector for the supporting frame, is an essential connecting accessory in the steel pipe frame, playing the role of transferring the upper load to the foundation. However, traditional base connectors mostly adopt a fixed angle design. In the actual installation process, due to cutting, welding or uneven ground, the angle of the frame may deviate, reducing the installation accuracy and stability. Summary of the Invention

[0004] To solve the above problems, this utility model provides a base connector with adjustable pipe overlap angle that can effectively improve installation accuracy, optimize structural stress, and enhance stability by finely adjusting the overlap angle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a base connector with an adjustable pipe overlap angle, comprising a column support component and a crossbeam overlap component.

[0006] The column support component consists of a base and a riser, which are integrally cast. The base is an "L"-shaped plate structure with multiple mounting holes on its vertical end face and drainage holes on its horizontal end face. The riser is vertically positioned above the drainage holes on the horizontal end of the base, with its left side connected to the vertical end of the base. A vertically positioned positioning block with the same height as the riser is located at the midpoint of its right side. The positioning block has positioning holes that penetrate its front and back sides. The front of the riser has two column tightening holes that penetrate its wall thickness and have internal threads. The column tightening holes are arranged vertically, and each hole is fitted with an internal hexagonal threaded tightening plug.

[0007] The crossbeam overlapping component includes a cross seat and a cross tube, which are integrally cast. The cross seat is a trapezoidal plate structure, and the width of its long side is the same as the width of the horizontal end of the upright. The cross tube is horizontally arranged on the top surface of the cross seat. A groove matching the curvature of the side wall of the right side of the upright is opened on the left end face of the cross tube, and a slot matching the size of the positioning block is opened at the midpoint of the top left side of the cross tube. Rotating columns are respectively provided on the top surface of the cross tube on both sides of the slot. Rotating holes corresponding to the positioning holes of the positioning block are opened on the rotating columns. Two crossbeam tightening holes with internal threads are opened on the front side of the cross tube. The crossbeam tightening holes are arranged horizontally, and internal hexagonal external thread tightening plugs are installed in the holes respectively.

[0008] The crossbeam overlapping component is located on the right side of the column support component. The slot on the left side of the cross tube is engaged on the outer side wall of the lower part of the vertical tube. The two rotating columns on the top surface of the cross tube are located on the front and rear sides of the positioning column of the vertical tube, respectively. The rotating holes of the two rotating columns and the positioning holes of the positioning column are rotatably connected by a rotating shaft.

[0009] As an optimized solution for this case, in order to facilitate fine-tuning of the crossbeam, the top surface of the cross tube is provided with two fine-tuning tightening holes that penetrate its wall thickness and have internal threads, and the cross tube is provided with a detachable one-way bushing that can lock the fittings inserted into the cross tube in one direction; the fine-tuning tightening holes are arranged horizontally, and each hole is equipped with an internal hexagonal external thread fine-tuning plug, and the cross tube and the cross base below the fine-tuning tightening holes near the upright are provided with clearance holes.

[0010] As an optimization of this case, in order to improve the stability during vertical support, a locking hole that runs through the front and back of the positioning block is also provided below the positioning hole of the positioning block. Similarly, a matching hole corresponding to the locking hole is provided below the rotation hole of the rotating column, and the locking hole and the matching hole are connected and limited by a locking rod.

[0011] Beneficial effects: This utility model combines the use of column support components and crossbeam overlapping components. During use, the angle can be dynamically adjusted according to the actual overlapping situation of the steel pipe frame. When fine-tuning the angle of the column is required, the crossbeam is inserted into the horizontal tube, and its end pushes open the column and the base, causing the top of the column to tilt towards the horizontal base to complete the fine-tuning. When fine-tuning the crossbeam is required, the fine-tuning plug near the base is rotated to move it downwards, pushing the left end of the crossbeam inside the horizontal tube into the clearance groove, causing the crossbeam to tilt upwards to complete the fine-tuning. In summary, this utility model can effectively improve installation accuracy, optimize structural stress, enhance stability, effectively reduce on-site processing steps, and shorten the construction period by fine-tuning the overlapping angle.

[0025] Referring to Figures 1-4, the column support component consists of a base 1 and a riser 2, which are integrally cast. As can be seen from Figures 2 and 4, the base 1 is an "L"-shaped plate structure with multiple mounting holes on its vertical end face and drainage holes on its horizontal end face. The riser 2 is vertically positioned above the drainage holes on the horizontal end of the base 1, and its left side is connected to the vertical end of the base 1. A vertically positioned positioning block 3 is located at the midpoint of its right side, with the same height as the riser 2. The positioning block 3 has positioning holes that penetrate its front and back sides. The front of the riser 2 has two column tightening holes 4 that penetrate its wall thickness and have internal threads. The column tightening holes 4 are arranged vertically, and each hole is fitted with an internal hexagonal external thread tightening plug 5.

[0026] Referring to Figures 1-2 and 5-6, the crossbeam overlapping component includes a cross seat 6 and a cross tube 7. The cross seat 6 and the cross tube 7 are integrally cast. The cross seat 6 has a trapezoidal plate structure, and the width of its long side is the same as the width of the horizontal end of the upright 1. The cross tube 7 is horizontally arranged on the top surface of the cross seat 6. A groove matching the curvature of the side wall of the right side of the upright 2 is opened on the left end face of the cross tube 7, and a slot matching the size of the positioning block 3 is opened at the midpoint of the top left side of the cross tube 7. Rotating columns 8 are respectively provided on the top surface of the cross tube 7 on both sides of the slot. Rotating holes corresponding to the positioning holes of the positioning block 3 are opened on the rotating columns 8. Two crossbeam tightening holes 9 penetrating the wall thickness and with internal threads are opened on the front side of the cross tube 7. The crossbeam tightening holes 9 are arranged horizontally, and internal hexagonal external thread tightening plugs 5 are installed in the holes respectively.

[0027] Referring to Figures 3-6, a locking hole is also provided below the positioning hole of the positioning block 3, which also penetrates the front and back of the positioning block 3. Similarly, a matching hole corresponding to the locking hole is provided below the rotation hole of the rotating column 8, and the locking hole and the matching hole are connected and limited by the locking rod 11.

[0028] As can be seen from Figures 1 and 2, the crossbeam overlapping component is located on the right side of the column support component. The slot on the left side of the horizontal tube 7 is engaged with the outer side wall of the lower part of the vertical tube 2. The two rotating columns 8 on the top surface of the horizontal tube 7 are located on the front and rear sides of the positioning column of the vertical tube 2, respectively. The rotating holes of the two rotating columns 8 and the positioning holes of the positioning columns are rotatably connected by a rotating shaft 10. Example 2

[0029] As shown in Figures 3-4 and 8-9, the specific structure and implementation method are as shown in Example 1, except that: referring to Figures 8 and 9, the top surface of the horizontal tube 7 is provided with two fine-tuning tightening holes 12 that penetrate its wall thickness and have internal threads, and the horizontal tube is provided with a detachable one-way bushing that can lock the pipe fittings inserted into the horizontal tube in one direction.

[0030] When in use, if it is necessary to fine-tune the overlap angle of the upright, refer to Figure 7. Insert the crossbeam into the horizontal tube 7. The end of the crossbeam pushes open the upright tube 2 and the base 1, so that the top of the upright tube 2 tilts towards the horizontal base 6 to complete the fine-tuning of the upright. If it is necessary to fine-tune the overlap angle of the crossbeam, refer to Figure 9. Rotate the fine-tuning plug 13 near the base 1 to move it downward and push the left end of the crossbeam in the horizontal tube 7 into the clearance groove. At the same time, another fine-tuning plug 13 is adjusted in coordination. The one-way bushing is adjusted to the bottom of the horizontal tube 7 to fix the crossbeam, so that the crossbeam tilts upward to complete the fine-tuning.

[0031] When there is no need to adjust the overlap angle of the pipe fittings, refer to Figure 1. Insert the locking rod between the locking hole and the mating hole to lock the connection and then proceed with the assembly.
