Description

Technical Field

[0001] This utility model relates to the field of heavy machinery technology, specifically to a stable crossbeam metal connector. Background Technology

[0002] In modern architecture and mechanical engineering, beams, as crucial load-bearing components, play a decisive role in the safety and reliability of the overall structure through their stable connections with other structural parts. Currently, most common metal connectors for beams use multiple bolts for fixing to achieve their connection function. While this traditional connection method can meet basic connection requirements to a certain extent, it has many significant drawbacks.

[0003] During installation, the large number of bolts required necessitates individual tightening by operators, which is not only time-consuming and labor-intensive but also demands a high level of skill and patience. In large-scale projects or the assembly of complex structures, the use of numerous bolts slows down the installation process and severely impacts project efficiency.

[0004] The inconveniences of multi-bolt connections become even more apparent when it comes to later maintenance, repairs, or structural adjustments and modifications. Numerous bolts need to be removed sequentially, making the process cumbersome and prone to problems such as bolt loss or thread damage. This difficulty increases exponentially, especially in space-constrained or harsh working environments, significantly hindering normal equipment maintenance and flexible structural adjustments.

[0005] Therefore, there is an urgent need for a new type of crossbeam metal connector that can overcome the above-mentioned defects of existing multi-bolt connectors, and significantly improve the ease of assembly and disassembly while ensuring connection stability, so as to meet the growing needs of modern engineering construction and machinery manufacturing industries. Utility Model Content

[0006] To address the aforementioned problems, this invention presents a stable metal connector for crossbeams.

[0007] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0008] A stable crossbeam metal connector includes a steel column. Each of the four sides of the outer wall of the steel column has a screw hole. A connecting seat is movably fitted onto the outer wall of the steel column. Each of the four sides of the outer wall of the connecting seat has a through hole. Fixed plates are provided at the upper and lower ends of the front side wall of the connecting seat. A support plate is provided on the front side wall of the fixed plate. Two bases are provided on the top wall of the support plate. A screw hole is provided on the upper surface of each base. A top seat is provided above the base. Support seats are provided on both sides of the top wall of the top seat and rest on the bases. A through hole is provided through the outer wall of the top seat. A bolt is inserted into the through hole, and the outer wall of the bolt is screwed into the screw hole.

[0009] It also includes a crossbeam, on the outer wall of which are provided multiple insertion holes.

[0010] Furthermore, the number of screw holes one and through holes one are equal, and their positions are arranged opposite to each other.

[0011] Furthermore, the base and the top seat are of equal length and are arranged to overlap vertically.

[0012] Furthermore, one end of the crossbeam is provided with four insertion holes, which are distributed on the upper and lower sides of the crossbeam.

[0013] The beneficial effects of this utility model are:

[0014] This utility model's crossbeam metal connector significantly improves the ease of assembly and disassembly. Compared with traditional multi-bolt connections, its unique structural design eliminates the need for tediously tightening numerous bolts one by one during installation. By initially positioning the crossbeam on the base and then using a rotatable top seat and support seat in conjunction with a small number of bolts for clamping and fixing, the installation steps and time are greatly reduced. During disassembly, simply loosen the bolts and rotate the top seat and support seat to easily lift the crossbeam and complete the disassembly. This effectively avoids the inconvenience caused by disassembling numerous bolts in traditional connection methods. It is especially suitable for the frequent assembly and disassembly needs in large-scale projects or complex structures, greatly improving the efficiency of engineering construction and the convenience of equipment maintenance.

[0015] Due to its simple and efficient installation and disassembly process, this invention significantly reduces labor and time costs. During installation, it minimizes the effort and time spent by operators on numerous bolt operations, reducing over-reliance on operator skill levels and enabling even ordinary workers to complete connection tasks quickly and accurately. During equipment maintenance and structural modifications, the rapid disassembly process shortens downtime, reducing the impact of repairs or modifications on the overall project or production schedule. This saves companies substantial human and time resources, improving economic efficiency and market competitiveness. Attached Figure Description

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figure 1-3 As shown, a stable crossbeam metal connector includes a steel column 1. Each of the four sides of the outer wall of the steel column 1 has a screw hole 1. A connecting seat 2 is movably fitted onto the outer wall of the steel column 1. Each of the four sides of the outer wall of the connecting seat 2 has a through hole 3. Fixing plates 4 are provided at the upper and lower ends of the front side wall of the connecting seat 2. A support plate 5 is provided on the front side wall of the fixing plate 4. Two bases 6 are provided on the top wall of the support plate 5. A screw hole 7 is provided on the upper end face of the base 6. A top seat 8 is provided above the base 6. Support seats 9 are provided on both sides of the top wall of the top seat 8 and rest on the base 6. A through hole 10 is provided through the outer wall of the top seat 8. A bolt 11 is inserted into the through hole 10, and the outer wall of the bolt 11 is screwed into the screw hole 7.

[0024] It also includes a crossbeam 12, on the outer wall of which are provided multiple insertion holes 13.

[0025] Furthermore, the number of screw holes 1 and through holes 3 are equal and their positions are opposite. The connecting seat 2 is fitted onto the outer wall of the steel column 1, and the bolt is passed through the through hole 3 and screwed into the screw hole 1 to facilitate the fixing of the connecting seat 2.

[0026] Furthermore, the base 6 and the top seat 8 are of equal length and are arranged in an overlapping manner. The crossbeam 12 drives the insertion hole 13 to be placed above the top seat 8 and sits down on the support plate 5. The bolt 11, the top seat 8, the support seat 9 and the base 6 are passed through the insertion hole 13, so that the crossbeam 12 can be easily clamped onto the outer wall of the base 6 through the insertion hole 13.

[0027] Furthermore, one end of the crossbeam 12 is provided with four insertion holes 13, which are distributed on the upper and lower sides of the crossbeam 12. The crossbeam 12 is positioned above the top seat 8 and then lowered onto the support plate 5. The crossbeam 12 is then secured to the outer wall of the base 6 through the insertion holes 13, which provides initial positioning and fixation for the crossbeam 12 and prevents it from falling off. The top seat 8 is rotated 90 degrees, and the bolt 11 is rotated to fix the crossbeam 12. The four top seats 8 and the support seat 9 are fixed to the crossbeam 12, which fully fixes the crossbeam 12 and improves the stability of the fixation.

[0028] The detailed connection methods are well-known technologies in the field. All components in this solution are general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0029] One specific application of this embodiment is:

[0030] When in use, the connecting seat 2 is fitted onto the outer wall of the steel column 1 and connected and fixed by welding or bolt tightening. A crossbeam 12 is fixed on the outer wall of the connecting seat 2. Two sets of fixing plates 4 need to be welded on one side of the connecting seat 2. The number of fixing plates 4 installed on the outer wall of the connecting seat 2 can be selected according to the need to fix the crossbeam 12.

[0031] Position the crossbeam 12 with the insertion hole 13 above the top seat 8 and lower it onto the support plate 5. Pass the bolt 11, top seat 8, support seat 9, and base 6 through the insertion hole 13. Secure the crossbeam 12 to the outer wall of the base 6 through the insertion hole 13, providing initial positioning and fixing to prevent it from falling off. Rotate the top seat 8 and support seat 9 9 90 degrees, placing the two support seats 9 on the front and rear sides of the base 6. Move the top seat 8 and support seat 9 downwards to press them onto the outer wall of the crossbeam 12. Rotate the bolt 11 to press the top seat 8 and support seat 9 onto the outer wall of the crossbeam 12, thus fixing the crossbeam 12. Fix the four top seats 8 and support seats 9 onto the crossbeam 12 to fully fix the crossbeam 12 and improve its stability.

[0032] When it is necessary to disassemble the crossbeam 12, loosen multiple bolts 11, rotate the top seat 8 to drive the support seat 9 to rotate and overlap with the base 6, lift the crossbeam 12 and the insertion hole 13 upward, and remove the insertion hole 13 from the outer wall of the base 6, thereby disassembling the crossbeam 12.

[0033] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
