Description

Technical Field

[0001] This utility model relates to the field of dining table legs technology, specifically a sturdy dining table leg. Background Technology

[0002] A dining table typically consists of a tabletop, a metal frame, and legs. The metal frame is fixed to the bottom of the tabletop with screws, and the legs are fixed to the bottom of the metal frame.

[0003] The above installation method has the following problems: 1. Since the table legs are directly welded to the metal frame, the joint position of the curved surfaces is prone to misalignment, which makes the table legs easy to be crooked after welding, resulting in high processing difficulty; 2. The metal frame is directly fixed to the bottom of the tabletop, and there are no tie rods at the corners of the frame. If it is subjected to external tilting pressure, the frame is prone to deformation. Therefore, we have invented a stable table leg. Utility Model Content

[0004] The purpose of this invention is to provide a sturdy dining table leg to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sturdy dining table leg includes a right-angle connector. Both ends of the right-angle connector are connected to a metal dining table frame, and the bottom of the right-angle connector is fixedly connected to the dining table leg. Two sets of metal dining table frames have four sets of insertion holes at their facing ends. A pull rod is installed at the facing ends of the two sets of metal dining table frames. An undercut is fixed at both ends of the pull rod, extending into the inner wall of the insertion hole. A through hole is formed on the inner side of the right-angle connector, and a second through hole is formed in the middle of the pull rod. A connecting corner block is welded to the right-angle portion of the inner side of the right-angle connector. A thickened section is formed in the middle of the connecting corner block, and an internally threaded through hole is formed in the middle of the thickened section. A screw is installed on the pull rod, passing through the second through hole and connecting to the internally threaded through hole.

[0007] In a preferred embodiment of this utility model, the bottom of the right-angle connector is provided with an arc-shaped positioning groove, and the top of the table leg is provided with an arc surface. The arc surface is connected to the arc-shaped positioning groove and then welded.

[0008] In a preferred embodiment of this utility model, the inner walls of both ends of the right-angle connector are provided with stepped grooves, and the two ends of the metal table frame are provided with stepped protrusions. The stepped protrusions of the metal table frame are inserted into the stepped grooves of the right-angle connector.

[0009] In a preferred embodiment of this utility model, the connecting corner block is provided with folded portions at both ends, and the folded portions are fitted with the right-angle connector and welded together.

[0010] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0011] The bottom of the right-angle connector has an arc-shaped positioning groove, and the top of the table leg has an arc surface. The arc surface is connected to the arc-shaped positioning groove and then welded. The arc-shaped positioning groove is designed to be able to position and connect with the table leg to prevent the table leg from tilting when it is welded to the right-angle connector.

[0012] The pull rod is connected to the insertion hole of the dining table metal frame through an inverted buckle to position the two dining table metal frames. Then, the pull rod is fixed to the right-angle connector by the screw, thereby increasing the fixation of the table corner and preventing the dining table metal frame from deforming due to tilting gravity.

[0013] The connecting corner block replaces the commonly used nut. Compared to the nut, the connecting corner block can fit right-angle connectors, making it more convenient when using spot welding. The thickened part can be opened with an internal threaded through hole, making the connection between the connecting corner block and the screw more stable. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] Please refer to Figure 1-7 A sturdy dining table leg includes a right-angle connector 100, with two ends of the right-angle connector 100 connected to a metal table frame 200, and a table leg 400 fixedly connected to the bottom of the right-angle connector 100. Two sets of metal table frames 200 have four sets of insertion holes 210 at their facing ends. A pull rod 300 is installed at the two sets of metal table frames 200, with buckles 320 fixedly installed at both ends, extending into the inner wall of the insertion hole 210. A through hole 110 is formed on the inner side of the right-angle connector 100, and a second through hole 310 is formed in the middle of the pull rod 300. A corner block 600 is welded to the right-angle portion of the inner side of the right-angle connector 100, and the corner block 600 has a thickened portion 610 in the middle. The thickened part 610 has an internally threaded through hole 620 in the middle. A screw 500 is installed on the pull rod 300. The screw 500 passes through the through hole 310 and connects to the internally threaded through hole 620. Specifically, the pull rod 300 is connected to the insertion hole 210 of the dining table metal frame 200 through the buckle 320 to position the two dining table metal frames 200. Then, the pull rod 300 is fixed to the right-angle connector 100 by the screw 500, thereby increasing the fixation of the table corner and preventing the dining table metal frame 200 from deforming due to tilting gravity. The connecting corner block 600 replaces the commonly used nut. Compared with the nut, the connecting corner block 600 can fit the right-angle connector 100, which is more convenient when using the spot welding process. The thickened part 610 is designed to have an internally threaded through hole 620, making the connection between the connecting corner block 600 and the screw 500 more stable.

[0025] The right-angle connector 100 has an arc-shaped positioning groove 120 at its bottom, and the table leg 400 has an arc-shaped surface 410 at its top. The arc-shaped surface 410 is connected to the arc-shaped positioning groove 120 and welded together. The arc-shaped positioning groove 120 is designed to be positioned and connected to the table leg 400 to prevent the table leg 400 from tilting when it is welded to the right-angle connector 100.

[0026] The right-angle connector 100 has stepped grooves on its inner walls at both ends, and the metal table frame 200 has stepped protrusions at both ends. The stepped protrusions of the metal table frame 200 are inserted into the stepped grooves of the right-angle connector 100.

[0027] The connecting corner block 600 has folded portions 630 at both ends. The folded portions 630 are fitted with the right-angle connector 100 and welded together.

[0028] The working principle of this utility model is as follows: the connecting corner block 600 is provided with folded parts 630 at both ends, the folded parts 630 are attached to the right angle connector 100 and welded together, the pull rod 300 is provided with buckles 320 at both ends, the buckles 320 extend into the inner wall of the insertion hole 210 of the metal frame of the dining table 200, and then the screw 500 is passed through the through hole 310 of the pull rod 300 and connected to the internal threaded through hole 620 of the connecting corner block 600.
