Description

Technical Field

[0001] This utility model relates to the field of sealing technology, and in particular to an easily disassembled and installed oil-proof sealing device for industrial equipment. Background Technology

[0002] Currently, there are some problems with sealing oil leaks in the cable holes of large equipment used for monitoring mechanical condition parameters (such as cables monitoring temperature, vibration, and displacement) in thermal power plants and chemical plants: 1. Installers directly apply blue glue to the cable holes. While this may seem fine in the short term, the glue does not adhere well to the cable, resulting in poor sealing. Moreover, over time, the blue glue adheres tightly to the metal, requiring sharp tools to pry it open for subsequent cable removal, which is time-consuming, laborious, and can easily damage the cable. 2. In addition to blue glue, another method is to use rubber plugs. However, these commonly used rubber plugs harden over time, failing to seal the detection lines. Furthermore, hardened plugs are difficult to remove from the holes.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an easy-to-disassemble oil-proof sealing device for industrial equipment, which facilitates the disassembly of the aged sealing structure and makes maintenance convenient.

[0005] The technical solution of this utility model is as follows: An easily detachable and assembleable oil-proof sealing device for industrial equipment is provided, comprising: a mounting base, a pull rod, a rubber plug, a pressure ring, and a locking nut; the mounting base is provided with a first connecting groove and a pressing groove communicating with the first connecting groove; the pull rod includes: a support plate and a pull rod connected to the support plate; the rubber plug is provided with a rod hole and several wire holes; the locking nut is provided with a top-fitting groove and a second connecting groove communicating with the top-fitting groove; the pressing groove is connected to the top-fitting groove, one end of the rubber plug abuts against the pressing groove, one end of the pressure ring abuts against the pressing groove, the rubber plug abuts against the pressure ring, the pull rod passes through the rod hole, the rubber plug is disposed between the support plate and the pressure ring, and the mounting base and the locking nut are connected by threads. In application, tightening the locking screw will push the pressure ring towards the rubber plug. Because the rubber plug is pressed against the pressing groove, it will be squeezed, thereby allowing the wire holes of the rubber plug to firmly clamp the cable, thus achieving a sealing effect. When disassembly is required, loosen the locking screw to disengage it from the mounting base, then pull the plug rod to remove the rubber stopper from the clamping groove, thus achieving disassembly. Compared to existing technologies, the plug rod allows for quick removal of the rubber stopper, greatly facilitating disassembly.

[0006] Furthermore, the rubber stopper is provided with a first contraction taper, and the clamping groove is provided with a second contraction taper. The first contraction taper and the second contraction taper cooperate with each other. When the pressure ring squeezes the rubber stopper, the first contraction taper and the second contraction taper can provide radial pressure to the rubber stopper, thereby enabling the wire hole to better clamp the cable.

[0007] Furthermore, the tray is provided with a wire groove, which mates with the wire hole. The wire groove can separate multiple cables, facilitating application.

[0008] Furthermore, the rubber stopper has an axial cut that communicates with the wire hole. The axial cut facilitates the insertion of the cable into the wire hole near the axial cut.

[0009] Furthermore, the pressure ring is provided with a positioning piece, and the pressing groove is provided with an anti-rotation groove. The anti-rotation groove cooperates with the positioning piece to restrict the rotation of the pressure ring. When the locking nut rotates and squeezes the pressure ring, the pressure ring is prevented from rotating, thereby preventing the rubber plug from rotating and preventing the wire from twisting.

[0010] Furthermore, an anti-fall step is provided in the first connecting groove to prevent the stopper rod from falling out of the first connecting groove.

[0011] Furthermore, a redundant groove is provided at the bottom of the top groove, which is used to provide space for deformation when the bearing ring deforms.

[0012] Furthermore, the mounting base is provided with an external thread, which is located on the outside of the clamping groove, and the side wall of the top groove is provided with an internal thread, with the external thread engaging with the internal thread.

[0013] Using the above solution, this utility model provides an easily disassembled and installable oil-proof sealing device for industrial equipment. In application, tightening the locking screw pushes the pressure ring towards the rubber stopper. Because the rubber stopper is pressed against the compression groove, it is squeezed, allowing the wire hole of the rubber stopper to firmly clamp the cable, thus achieving a sealing effect. When disassembly is required, loosen the locking screw to disengage it from the mounting base, then pull the pull rod to pull the rubber stopper out of the compression groove, achieving disassembly. Compared with existing technologies, the pull rod can quickly remove the rubber stopper, greatly facilitating disassembly. This utility model achieves oil-proof sealing through compression and contraction. Its features include: the rubber stopper has moderate hardness and will not harden during equipment maintenance cycles, providing excellent sealing performance; and the sealing device is easy to disassemble and install, greatly reducing the time required for equipment disassembly during maintenance. An anti-rotation groove is designed in the mounting base, which cooperates with the positioning piece of the pressure ring, so that when the locking nut is tightened, it will not cause the rubber stopper to rotate, preventing wire tangling.

The anti-rotation groove 28 cooperates with the positioning piece 23 to restrict the rotation of the pressure ring 18. When the locking nut rotates and squeezes the pressure ring 18, the pressure ring 18 is prevented from rotating, thereby preventing the rubber plug from rotating and preventing the wire from twisting.

[0025] In this embodiment, an anti-fall step 24 is provided in the first connecting groove 10 to prevent the stopper rod from falling out of the first connecting groove 10.

[0026] In this embodiment, a redundant groove 25 is provided at the bottom of the top groove 16. The redundant groove 25 is used to provide space for deformation when the pressure ring 18 deforms.
