Description

Technical Field

[0001] The utility model relates to a push rod for glass products, in particular to a glass push rod based on a dry etching process. Background Art

[0002] The push rod for glass products is a metal product used in conjunction with glass. The push rod made of metal does not have the performance of the push rod made of PI material. The push rod made of PI material is relatively soft compared with the steel material. When the length reaches a certain length, the top support force is insufficient, resulting in swaying at the top and insufficient stability. However, the connection stability after the combination of the two is poor, and the PI material is easy to separate from the steel material. Therefore, it is necessary to design a push rod structure and a connection structure for glass products that can both maintain the performance of the PI material and have the hardness of the steel material.

[0003] Therefore, the existing push rods for glass products need to be further improved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a glass push rod based on a dry etching process, which can not only maintain the performance of the PI material but also have the hardness of the steel material, and at the same time has a stable connection structure.

[0005] In order to achieve the above purpose, the utility model adopts the following scheme:

[0006] A glass push rod based on a dry etching process includes a first rod and a second rod. The first rod is made of a metal material. A threaded connection structure is provided between the first rod and the second rod. An outer sleeve made of PI material is sleeved outside the second rod. An outer serrated pattern is provided on the circumferential outer wall of the second rod, and an inner serrated pattern is provided on the inner wall of the outer sleeve. A pressing edge is provided at the lower end of the outer sleeve.

[0007] Further, the metal material of the first rod is steel material.

[0008] Further, the threaded connection structure includes an external threaded rod provided at the upper end of the first rod, and a threaded hole is provided at the lower end of the second rod. The external threaded rod is threadedly connected to the threaded hole.

[0009] Further, the serrations of the outer serrated pattern are partial along the axial direction of the second rod, and the serrations of the inner serrated pattern are partial along the axial direction of the outer sleeve.

[0010] Further, the outer serrated pattern and the inner serrated pattern are arranged in an inverted hook shape.

[0011] Further, the pressing edge is provided between the upper end face of the first rod and the lower end face of the second rod.

[0012] In summary, the beneficial effects of the present utility model compared with the prior art are as follows:

[0013] The present utility model solves the deficiencies existing in the ejector rod structure for existing glass products. Through the structural arrangement of the present utility model, the following advantages are achieved. It can not only maintain the performance of the ejector rod supported by PI material, which is a new type of high-temperature resistant thermosetting engineering plastic with excellent electrical insulation, wear resistance, high-temperature radiation resistance, and physical and mechanical properties, but also has the high hardness of steel material, ensuring the stability and service life of a relatively long ejector rod. At the same time, a reverse serrated connection structure is provided between the outer sleeve body made of PI material and the ejector rod to prevent the PI material from falling off, improving the connection stability. The pressing edge further improves the connection stability, and the structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
