Problems solved by technology

[0003] The perforated connecting sleeves currently used are all plastic decorative sleeves. The purpose is to facilitate installation and improve installation efficiency. However, plastic decorative sleeves do not have a sealing effect. In a humid environment, moisture can easily escape from the upper end of the plastic decorative sleeve and the large diameter. The pipe enters the gap between the perforations, causing the opening and inner wall of the large-diameter pipe to corrode, and the rust water may flow out along the plastic decorative sleeve, thereby affecting the service life and appearance of the guardrail and window. The connection fails, leaving a safety hazard; if the plastic decorative sleeve is replaced with an elastic sleeve made of rubber material, the sealing effect will be improved and the corrosion of the opening and inner wall of the large-diameter pipe will be prevented. The contact of the opening of the pipe will cause excessive installation resistance, which makes the installation efficiency low, and the cost of rubber materials is high, which is not conducive to popularization and application

Abstract

The invention discloses a pair punching-hole seal sleeve for penetration and connection of a tubular product. The seal sleeve comprises a seal sleeve body which is of a cylinder shape, wherein the upper end and the lower end of the seal sleeve body are provided with clamping edges which are matched with a pair punching hole; the clamping edge on the upper end of the seal sleeve body is provided with a first pressing block; and the lower end surface of the first pressing block is provided with a soft seal ring which can be pressed to the opening of the upper end of the pair punching hole. The pair punching-hole seal sleeve for penetration and connection of the tubular product has the advantages of good sealing property, simple structure and low cost, and is convenient to manufacture, and is convenient and rapid to install.

Description

technical field [0001] The invention relates to fittings used for the insertion connection of pipes, in particular to a pair of perforation sealing sleeves for the insertion connection of pipes. Background technique [0002] Existing guardrails and protective windows often use a connection structure in which metal pipes are interspersed with each other. This connection structure is usually to open a hole of a suitable size on the large-diameter pipe, put a plug-in decorative sleeve on the end of the small-diameter pipe, and then install the small-diameter pipe. One end of the pipe is inserted into the opening of the large-diameter pipe together with the plug-in decorative sleeve, which is easy to install and does not require welding connections. [0003] The perforated connecting sleeves currently used are all plastic decorative sleeves. The purpose is to facilitate installation and improve installation efficiency. However, plastic decorative sleeves do not have a sealing ef...
