[0003] The unilateral hole connection sleeves currently used are all plastic decorative sleeves, the purpose of which is to facilitate installation and improve installation efficiency, but the plastic decorative sleeve does not have a sealing effect, and moisture can easily escape from the upper end of the plastic decorative sleeve and the large The gap between the unilateral holes of large-diameter pipes enters, causing the opening and inner wall of large-diameter pipes to corrode, and the rust water may flow out along the plastic decorative sleeve, thereby affecting the service life and appearance of guardrails and protective windows. Will cause the connection to fail, leaving a security risk
If the plastic decorative sleeve is replaced with an elastic sleeve made of rubber material, the sealing effect will be improved. However, most of the current rubber elastic sleeves are directly inserted into the gap between the pipe and the unilateral hole without a fixed structure, so after installation The rubber elastic sleeve is easy to fall off from the hole on one side

The invention discloses a one-side hole waterproof seal assembly for connecting pipes in an inserting mode. The one-side hole waterproof seal assembly comprises an elastic seal sleeve, a bottom plug cover and a bottom plug which is sleeved at the bottom end of a pipe, and the bottom plug is hung at the edge of an opening of the one-side hole; and the elastic seal sleeve comprises a first extrusion seal portion, a second extrusion portion and a connection portion, wherein the first extrusion seal portion is compressed between the outer wall of the pipe and the inner wall of the bottom plug, the second extrusion seal portion is compressed on the periphery of the one-side hole through the bottom plug cover, and the connection portion is used for connecting the first extrusion seal portion and the second extrusion seal portion. The one-side hole waterproof seal assembly has the advantages of being simple and compact in structure, low in cost, good in sealing performance, stable in installation and the like.
Description
technical field [0001] The invention relates to fittings used for pipe penetration connection, in particular to a single side hole sealing assembly used for pipe penetration connection. 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 unilateral hole connection sleeves currently used are all plastic decorative sleeves, the purpose of which is to facilitate installation and improve installation efficiency, but the plastic decorative sleeve does not have a seali...
