Specific implementation mode
In order to further appreciate that the contents, features and effects of the utility model, following instance is lifted, and coordinate attached drawing detailed It is described as follows:
As shown in Figure 1, the utility model provides a kind of cable seal cylinder, including top connection 1, connecting cylinder 2, lower contact 3, institute It states 2 both ends of connecting cylinder and is connected through a screw thread top connection 1 and lower contact 3 respectively;It is set between the top connection 1 and the connecting cylinder 2 It is equipped with the first sealing mechanism 4;The second sealing mechanism 5 is provided between the lower contact and the connecting cylinder.First sealing It is additionally provided between mechanism 4 and the connecting cylinder 3 with the threaded hole 7 for blocking screw 71.Second sealing mechanism 5 and the company O-ring seal 8 is additionally provided between connect cylinder 3.
First sealing mechanism 4 includes a pair of of crushing block (411,412 with second sealing mechanism 5;511, 512) be open cushion rubbers (421,422 with two;521,522);The pair of crushing block (411,412;511,512) it is arranged between There are two the cushion rubbers (421,422 that is open;521,522).Shown in Fig. 2, each crushing block (411,412;511,512) it is two valves Formula, a valve have convex shoulder (411a, 412a;511a, 512a);One valve fluted (411b, 412b;511b, 512b);Between two valves It is fixed by clamp spring 6.Shown in Fig. 3, each opening cushion rubber (421,422;521,522) opening inclination angle is 30 °.
By top connection 1, connecting cylinder 2, lower contact 3, crushing block (411,412 in the utility model;511,512), be open glue Circle (421,422;521,522), clamp spring 6, O-ring seal 8 and blocking screw 71 form.Top connection 1 passes through external screw thread and connection Cylinder 2 connects, and connecting cylinder 2 is connected by external screw thread and lower contact 3, between top connection 1 and connecting cylinder 2, connecting cylinder 2 and under connect Have between first 3 positioned at two crushing blocks (411,412;511,512) two opening cushion rubbers (421,422 between;521,522), Make opening cushion rubber (421,422 by tightening the screw thread between top connection 1 and connecting cylinder 2, between connecting cylinder 2 and lower contact 3; 521,522) it compresses the inner wall of cable seal cylinder and cable outer wall plays sealing function, crushing block (411,412;511,512) it is Split-type structure is fixed together by clamp spring 6, and 2 lower part of connecting cylinder is sealed equipped with O types sealing ring 8 and lower contact 3, connecting cylinder There is threaded hole 7 on 2, block screw 71 and be mounted on the threaded hole 7, has sealing screw thread that the cable seal cylinder is made to pacify in lower contact 3 Loaded on miscellaneous equipment.
