Description

Technical Field

[0001] The utility model relates to the technical field of support and hanger connecting pieces, in particular to a toothed component for a support and hanger. Background Art

[0002] With the development of science and technology, large-diameter pipes are needed in factories, fire protection, petrochemical and other industries. The gravity load is large, the horizontal longitudinal impact force brought by pressurized water pipes is large, and the span is large, which places high requirements on the bearing capacity of supports and hangers and their connecting parts.

[0003] In the support and hanger system, the toothed gasket is usually used in conjunction with toothed connectors, hangers, beams, hangers and other components to form a complete support system. The toothed gasket in the support and hanger is a connector used to adjust the height, level and position of pipes or equipment. Toothed gaskets and toothed connectors are usually used together, and their tooth structures engage with each other to form a stable connection. An engagement groove is formed between adjacent teeth of the existing toothed gasket, and the groove width of the engagement groove along its depth direction is equal. When subjected to external forces such as gravity, the root of the tooth (i.e., the bottom of the engagement groove) may be subjected to greater shear stress. Due to stress concentration, the root of the tooth of the toothed gasket is prone to shear fracture, which not only affects the stability of the support and hanger system, but also may cause safety hazards; in addition, most of the existing toothed gaskets are made of castings. This production process is not only costly, but also has relatively low production efficiency and a long delivery cycle.

[0004] The above defects need to be solved urgently. Utility Model Content

Of course, in actual design, the depth a of the first connecting groove 12 can be designed according to actual needs.

[0038] like Figure 3 , Figures 6 to 8As shown, in the present embodiment, the shape of the first connecting tooth 11 of the toothed gasket 1 is narrow at the top and wide at the bottom, and the shape of the second connecting tooth 22 of the toothed connector 2 is narrow at the top and wide at the bottom, so that the root of the first connecting tooth 11 and the root of the second connecting tooth 22 have better shear resistance, and at the same time, the toothed gasket 1 has a sliding guiding effect during the meshing process with the toothed connector 2, and the strength is higher and more reliable during the force transmission process, and it is more conducive to the deeper insertion of the first connecting tooth 11 and the second connecting tooth 22 when subjected to tightening pressure, thereby improving the stability of the connection between the toothed gasket 1 and the toothed connector 2.

[0039] like Figures 1 to 4 As shown, in this embodiment, the toothed gasket 1 includes a connection base 13 and a connection portion 14, wherein the connection portion 14 is arranged at the bottom of the connection base 13, and the first connection teeth 11 are arranged on the side of the connection portion 14. The first connection teeth 11 can be arranged in two rows, and the two rows of first connection teeth 11 are symmetrically arranged on both sides of the connection portion 14, which can improve the connection stability between the toothed gasket 1 and the toothed connector 2. Of course, the first connection teeth 11 can also be designed to be three or four rows, and the three or four rows of first connection teeth 11 are respectively arranged on the side of the connection portion 14.

The first side surface 121, the second side surface 122, the arc surface 123 and the two side surfaces corresponding to the two first connecting teeth 11 are arranged to form the first connecting groove 12. The arrangement of the arc surface 123 facilitates the cold heading or stamping of the first connecting groove 12, thereby improving production efficiency. At the same time, the arrangement of the arc surface 123 makes it easier for the first connecting groove 12 to adhere to the precipitated coating layer during the electrogalvanizing process or the Dacromet process, thereby ensuring the anti-corrosion effect. In addition, the radius r of the arc surface 123 is 1 mm to 2 mm, and the radius r of the arc surface 123 can be designed to be 1.5 mm. Of course, in actual design, the radius r of the arc surface 123 can be designed according to actual needs.

At the same time, the setting of the arc surface 123 makes it easier for the first connecting groove 12 to adhere to the precipitated coating during the electrogalvanizing process or the Dacromet process, thereby ensuring the anti-corrosion effect. In addition, the radius r of the arc surface 123 is 1 mm to 2 mm, and the radius r of the arc surface 123 can be designed to be 1 mm. Of course, in actual design, the radius r of the arc surface 123 can be designed according to actual needs.

[0044] In another optional embodiment, the gap between two adjacent first connecting teeth 11 has a first side surface 121 and a second side surface 122, and an arc surface 123 is provided between the first side surface 121 and the second side surface 122. The first side surface 121, the second side surface 122, the arc surface 123 and the two side surfaces corresponding to the two first connecting teeth 11 are arranged to form the first connecting groove 12. The setting of the arc surface 123 facilitates the cold heading or stamping of the first connecting groove 12, thereby improving production efficiency. At the same time, the setting of the arc surface 123 makes it easier for the first connecting groove 12 to adhere to the precipitated coating during the electrogalvanizing process or the Dacromet process, thereby ensuring the anti-corrosion effect. In addition, the radius r of the arc surface 123 is 1 mm to 2 mm, and the radius r of the arc surface 123 can be designed to be 2 mm. Of course, in actual design, the radius r of the arc surface 123 can be designed according to actual needs.

In addition, the top width b of the first connecting tooth 11 is 1.5 to 2.5 mm, and the top width b of the first connecting tooth 11 can be designed to be any value in the range of 1.5 mm, 1.6 mm, 1.8 mm, 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.5 mm, etc. Of course, in actual design, the top width b of the first connecting tooth 11 can be designed according to actual needs.

[0046] like Figure 6 , Figure 7 As shown, in this embodiment, the number of the second connection grooves 23 in each row on the toothed connector 2 is greater than the number of the first connection teeth 11 in each row on the toothed gasket 1, so that the toothed gasket 1 can be adjusted along the adjustment hole 21, which is convenient for the toothed gasket 1 to be moved and installed on the adjustment hole 21, thereby adjusting the position of the toothed connector 2 and improving applicability. In addition, the adjustment range of the toothed gasket 1 in the adjustment hole 21 is 0 mm to 50 mm, which is convenient for adjusting the crossbar or other components connected to the toothed connector 2 to a horizontal state.

[0047] In this embodiment, the adjustment hole 21 is a long rectangular hole punched or laser cut, and the second connecting tooth 22 is extruded from the right-angled vertex of the long side of the rectangle of the adjustment hole 21 to the hypotenuse, so that the tooth depth and shape of the second connecting tooth 22 are better, ensuring the production convenience and the depth of the second connecting tooth 22, and facilitating the processing and forming of the second connecting tooth 22, improving production efficiency, thereby reducing production costs. In addition, there are no sharp corners or dead corners on the second connecting tooth 22, which is convenient for hot-dip galvanizing to flow and adhere, and it is not easy to block the teeth, ensuring the bite depth, thereby ensuring anti-slip performance. At the same time, the mold structure of the toothed connector 2 is stable and not easy to be damaged due to the sharp protrusions, so that it will not be damaged after long-term and multiple stamping.
