Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Embodiment 1:
Fig. 1 to Fig. 5 shows an embodiment 1 of the present utility model, as shown in Figure 1, of the present utility model for the interspersed Unilateral-hole black box that connects of tubing, the end stifled 2 that comprises elastic seal cartridge 1 and be socketed on tubing 3 bottoms, the opening end at the end stifled 2 is provided with clamping limit 21, during installation clamping limit 21 is placed the edge of opening outside of Unilateral-hole 4.Elastic seal cartridge 1 comprises the first crush seal section 11 of being pressed between stifled 2 inwalls in tubing 3 outer walls and the end, be pressed in the second crush seal section 12 between clamping limit 21 and Unilateral-hole 4 edge of opening and the joint 13 that is connected the first crush seal section 11 and the second crush seal section 12.Because stifled 2 extruding force at the bottom of 3 pairs of the tubing after installing, the clamping limit 21 that forces the end stifled 2 fixedly is clamped in Unilateral-hole 4 places with the second crush seal section 12 of elastic seal cartridge 1, thereby makes elastic seal cartridge 1 fixing, installs firmly, is difficult for getting loose.The first crush seal section 11 of elastic seal cartridge 1 is with the gap sealing between stifled 2 inwalls of tubing 3 outer walls and the end after installing, the second crush seal section 12 is with the gap sealing of Unilateral-hole 4 openings, form omnibearing tight seal structure, can play good waterproofing effect, avoid Unilateral-hole 4 openings and transverse tube inwall to produce corrosion, make guardrail, protect window maintenance outward appearance cleaning and good serviceability.
As shown in Figure 2, in the present embodiment, form the holding cavity 14 on clamping limit 21 between the first crush seal section 11, the second crush seal section 12 and the joint 13, after the installation, whole clamping limit 21 is teamed by elastic seal cartridge 1.
Such as Fig. 2, shown in Figure 3, in the present embodiment, the upper end open place of the first crush seal section 11 is provided with chamfering 111, makes the tubing 3 can easier insertion elastic seal cartridge 1, avoids because to insert resistance excessive and elastic seal cartridge 1 is brought into the end block up 2.
