Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work All other embodiment obtained, fall within the protection scope of the utility model.

As shown in figures 1 and 3, the utility model embodiment provides a kind of motor lines sealing device, including silica gel sealing seat 1, silicone-rubber seals 2, metal sealing tabletting 3 and metal compaction head 4, the silica gel sealing seat 1 is cylindrical and front end has Stop section 11, the silicone-rubber seals 2 are cylindrical and front and back is provided through threading hole 22, and the threading hole 22 is for powering Machine line passes through, and the silicone-rubber seals 2 are sleeved in the silica gel sealing seat 1 and front end block is on the stop section 11, institute It states metal sealing tabletting 3 to cover in 2 rear end of silicone-rubber seals, 4 front end of metal compaction head is supported in the metal sealing Fixation is tightened by screw thread in tabletting 3 and with the silica gel sealing seat 1.

This motor lines sealing device provided by the embodiment of the utility model, it is close by the way that metal compaction head 4 is screwed into silica gel Envelope seat 1 is simultaneously tightened to a certain extent, and 4 front end of metal compaction head supports metal sealing tabletting 3 and then squeezes silicone-rubber seals 2, is allowed The threading holes 22 of silicone-rubber seals 2 sufficiently shrink compacting across motor lines make simultaneously to achieve the purpose that sealed electric-motor line It obtains silicone-rubber seals 2 and squeezes 1 inner wall of silica gel sealing seat around, the close contact of the two is realized, to achieve the purpose that sealing； And metal sealing tabletting 3 and metal compaction head 4 are metal material, the two contact surface is smooth, and friction is small, and silica gel is close Frictional force is relatively large between sealing 2 and silica gel sealing seat 1 and metal sealing tabletting 3, and metal compaction head 4 will not band when rotating Dynamic metal sealing tabletting 3 rotates, and silicone-rubber seals 2 will not be caused to rotate, motor lines are avoided and distort or wind because of rotation. The installation easy to disassemble of the utility model energy, is reused, and facilitates the motor of maintenance, replacement damage.

As shown in figures 3 and 8, the structure of the silica gel sealing seat 1 is refined, the silica gel sealing seat 1 includes being located at front Seal section 12 and the fixed section 13 that is located behind, the seal section 12 be connected with the fixed section 13, the seal section 12 Internal diameter it is consistent with the diameter of the silicone-rubber seals 2, the inner wall in the outside of the silicone-rubber seals 2 and the seal section 12 Fitting, is more advantageous to sealing between the two.The stop section 11 is connected to 12 front end of seal section and relative to described close It seals section 12 inwardly to tighten, the front end of silicone-rubber seals 2 is stated so as to block residence.Further, the fixed section 13 is interior Diameter is greater than the internal diameter of the seal section 12, and the inside of the fixed section 13 has an internal thread screw thread 14, before the metal compaction head 4 It holds outside that there is outer silk screw thread 42, fixation is tightened by both cooperation realizations of internal thread screw thread 14 and outer silk screw thread 42.It is described The rear end of metal compaction head 4, which has, tightens table top 41, convenient to carry out tightening operation to metal compaction head 4 by spanner etc..

As shown in Figure 3 and Figure 4, as the preferred of the present embodiment, the front end of the silicone-rubber seals 2 be surrounded by first by Inclined-plane 21 is pressed, has match with first compression inclined-plane 21 first to compress inclined-plane 15 on the stop section 11, by setting The first compression inclined-plane 15 and the first compression inclined-plane 21 are set, so that the contact surface between 2 front end of silicone-rubber seals and silica gel sealing seat 1 Bigger, so that frictional force is bigger, silicone-rubber seals 2 will not more rotate, and sealing effect is more preferable.

As shown in figs. 4 and 7, as the preferred of the present embodiment, the rear end of the silicone-rubber seals 2 be surrounded by second by Inclined-plane 21 is pressed, has match with second compression inclined-plane 21 second to compress inclined-plane 31 on the inside of the metal sealing tabletting 3, Inclined-plane 31 and the second compression inclined-plane 21 are compressed by setting second, so that between 2 rear end of silicone-rubber seals and metal sealing tabletting 3 Contact surface it is bigger, so that frictional force is bigger, silicone-rubber seals 2 will not more rotate, further avoid motor lines distortion or twine Around.

As shown in figure 5, one of the embodiment as the silicone-rubber seals 2, the threading hole 22 is round hole and tool Have it is multiple, thus be suitable for more circular motor lines sealing.As shown in fig. 6, other one as the silicone-rubber seals 2 Kind embodiment, the threading hole 22 is flat hole, and is traditionally arranged to be one, to be suitable for the sealing of flat motor lines. Different threading holes 22 can be selected according to the type of motor lines in actual use, it is only necessary to replace corresponding silicone-rubber seals 2, so that the motor lines sealing device can be used for different line footpaths, in the motor lines of unlike material, it is versatile.

As shown in figure 8, all having chamfering inside and outside the front end of the metal compaction head 4 as the preferred of the present embodiment Inclined-plane reduces between the two so that 4 front end of metal compaction head and the contact area of the metal sealing tabletting 3 are smaller Frictional force further avoids the rotation of silicone-rubber seals 2.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
