Problems solved by technology

[0002] In the structural design of traditional equipment manufacturing, metal bolts are used to ensure the tensile strength requirements of the connecting parts between the plates. This metal material is used in the structural design of heating and energy-saving equipment, hot panels and cold panels. When connecting, due to the high thermal conductivity of the metal material, the temperature of the hot panel is quickly transmitted to the direction of the cold panel through the bolts, resulting in a large heat loss, and the energy saving rate of the product is low, and the ideal use effect cannot be achieved.

Embodiment 1

[0015] Such as figure 1 figure 2 The present invention provides a heat-insulating connecting column, which includes the upper and lower parts of the housing 1 and the end cover screw 2 with straight openings 3 bending welds 4, the outer shell 1 is provided with a hardened layer 5, the shell 1 and the Uniform spherical particles 6 are arranged inside the top and bottom symmetrical end cap bolts 2 .

[0016] In actual implementation, the material of the shell 1 is 316 material, and its exterior is provided with a hardened layer 5 with a thickness of 10-200um. Due to the increase in the process performance of the hardened layer 5, its tensile strength is the same as that of the original material. In comparison, the mechanical properties are increased by 118% to 462%, respectively, and the heat transfer cross-sectional area of ​​the shell 1 wall thickness is thinned, so it has the technical advantages of small volume, less heat conduction, and high tensile strength.

Embodiment 2

[0020] The difference between Embodiment 2 of the present invention and Embodiment 1 is that the lower part of the heat-insulating connecting column is provided with a nut seat 7 with thread 8 and welded 4 with the shell 1 as a whole.

[0021] In practice, since the lower nut seat 7 of the heat-insulating connecting column is provided with thread 8, bolts can be used for connection, which increases the scope of application.

Embodiment 3

[0023] The difference between Embodiment 3 of the present invention and Embodiment 1 is that the lower part of the heat insulating connecting column is provided with a cross opening 10 and an end cap 9 which is larger than the size of the shell.

[0024] In practice, since the lower part of the end cap 9 which is larger than the size of the shell is provided with a cross opening 10, it can be directly communicated with other components, increasing the scope of application.

[0025] The technical solution provided by the embodiments of the present invention has the following advantages:

[0026] The heat insulating connecting column provided by the embodiment of the present invention has the advantages of small volume, low thermal conductivity, high compressive strength and high tensile strength due to the optimized combination of structure, material and process between the shell and the end cap and the spherical particles inside. , The advantages of long service life.

Abstract

The invention discloses a heat insulation connecting column. The heat insulation connecting column is characterized in that the parts, provided with straight openings, of the upper portion and the lower portion of a shell and end cover screws are in bent welding, a hardened layer is arranged outside the shell, and uniform spherical particles are arranged in the shell and the end cover bolts which are symmetric up and down. Due to the optimized combination of structures and materials between the shell and end covers and the spherical particles in the shell and the end covers, the heat insulation connecting column has the technical advantages of small size, low thermal conductivity coefficient, high compressive strength and long service life.

Description

technical field [0001] The invention relates to a heat-insulating connection column, in particular to a heat-insulation connection column with low thermal conductivity, that is, tensile and compressive resistance. Background technique [0002] In the structural design of traditional equipment manufacturing, metal bolts are used to ensure the tensile strength requirements of the connecting parts between the plates. This metal material is used in the structural design of heating and energy-saving equipment, hot panels and cold panels. When connecting, due to the high thermal conductivity of the metal material, the temperature of the hot panel is quickly transmitted to the direction of the cold panel through the bolts, resulting in a large heat loss, and the energy saving rate of the product is low, and the ideal use effect cannot be achieved. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the invention provides a heat-insulating conne...
