Technical Field

[0001] The utility model relates to the technical field of metal connectors, in particular to the technical field of high-strength metal connectors. Background Art

[0002] Metal connectors are commonly used to connect parts together, achieving a specific connection between them. They are widely used, often used to connect steel structures in industrial and civil buildings, highway and railway bridges, towers, pipe supports, lifting machinery, and more.

[0003] Existing high-strength metals are difficult to punch due to their high strength, and screws and other connectors are not applicable, and they are also difficult to weld. Now it is necessary to vertically combine two high-strength metal plates. In view of this, we propose a high-strength metal connector. Utility Model Content

[0004] The main purpose of the utility model is to provide a high-strength metal connector to solve the problem in the related art that it is difficult to punch holes due to the high strength of the metal.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a high-strength metal connector is provided, including: a left clamping block and a right clamping block, the left clamping block and the right clamping block are threadedly connected by a screw rod, an optical axis is welded on the left clamping block, and the optical axis passes through a hole on the right clamping block, and both the left and right clamping blocks are provided with placement grooves for placing metal plates.

[0006] Furthermore, the left clamping block and the right clamping block are both provided with knobs, the knobs are threadedly connected to the left clamping block and the right clamping block, and a pressure plate is provided under the knobs, and the pressure plate knobs are fixedly connected.

[0007] Furthermore, a bearing is provided at one end of the screw rod, and the screw rod is connected to the left clamping block through the bearing.

[0008] Furthermore, the lower side surface of the pressing plate is rough.

[0009] Furthermore, the corners of the left clamping block and the right clamping block are both chamfered.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The utility model can connect metal plates that are too strong to be welded by using the left clamping block and the right clamping block. The utility model can connect metal plates within a certain width range by adjusting the screw rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0019] See also Figures 1 to 2 This embodiment provides a high-strength metal connector, comprising a left clamping block 1 and a right clamping block 2, which are threadedly connected by a screw 6. An optical axis 5 is welded to the left clamping block 1 and passes through a hole in the right clamping block 2. The optical axis 5 limits the rotational freedom of the right clamping block 2. The distance between the left and right clamping blocks 1 and 2 can be controlled by adjusting the screw 6, allowing metal plate parts within a certain width range to be connected.

[0020] It should be supplemented that a threaded hole is provided in the right clamping block 2 , and the screw rod 6 passes through the threaded hole and is threadedly connected thereto.

[0021] The left and right clamping blocks 1 and 2 are both provided with knobs 3, which are threadedly connected to the left and right clamping blocks 1 and 2. A pressure plate 4 is provided below the knobs 3, which is fixedly connected to the knobs 3. When the knobs 3 are rotated, the pressure plate 4 moves up and down a small distance to press the metal plate parts to be fixed.

[0022] A bearing 7 is provided at one end of the screw rod 6 , and the screw rod 6 is rotatably connected to the left clamping block 1 through the bearing 7 . The outer ring of the bearing 7 is fixed on the left clamping block 1 , and the inner ring is fixed to the screw rod 6 .

[0023] The lower side surface of the pressing plate 4 is roughened to increase the sliding friction between the pressing plate 4 and the lower metal plate 9, making the connection more stable.

[0024] The corners of the left clamping block 1 and the right clamping block 2 are both chamfered to prevent workers from being cut when using the clamping block and to prevent stress concentration.

[0025] It should be noted that a placement groove 10 is provided inside the left clamping block 1 and the right clamping block 2 , and the upper metal plate 8 and the lower metal plate 9 can be placed inside the placement groove 10 .

[0026] How it works: First, estimate the width of the upper and lower metal plates 8, 9 to be connected. Rotate screw 6 so that the gap between the left and right clamps 1 and 2 slightly exceeds the width of the lower and upper metal plates 9. It should be noted that the widths of the upper and lower metal plates 8, 9, must be the same. Push the lower metal plate 9 from below, so that it presses against the inner walls of the left and right clamps 1 and 2. Then, place the upper metal plate 8 from above, so that the bottom of the upper metal plate 8 contacts the lower metal plate 9. Next, rotate screw 6 to move the right clamp 2 toward the left clamp 1, pressing against the upper and lower metal plates 8, 9. Pressure from the left and right clamps 1 and 2 will secure the upper and lower metal plates 8, 9, firmly in place. Then, adjust knob 3 so that the pressure plate 4 presses firmly against the lower metal plate 9. Then adjust the other three knobs 3. Once adjusted, manually pull the upper and lower metal plates 8 and 9. If they don't move, the connection is secure. When disassembly is required, just adjust the knob 3 in the reverse direction to retract the pressure plate 4 and remove the pressure on the upper metal plate 8 and the lower metal plate 9. Then adjust the screw rod 6 to loosen the left clamping block 1 and the right clamping block 2, and remove the upper metal plate 8 and the lower metal plate 9.

[0027] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
