Abstract
The utility model provides a kind of outlet box being provided with cable protecting device, belong to cable protection technical field, comprise outlet box body and cable, the contact-making surface of described cable and outlet box body is provided with cable sealing ring, above described outlet box body, be also provided with cable protecting device; Described cable protecting device comprises sealing gland and helical spring, the inwall of described sealing gland offers the screw thread matched with helical spring, and helical spring one end is by being threaded into sealing gland inside; Cable is from top to bottom successively through outlet box body, sealing gland, helical spring protruding.The utility model has set up sealing gland and helical spring on the basis of existing structure; allow cable from top to bottom successively through outlet box body, sealing gland, helical spring protruding; cable is made effectively to be propped up overfill protection under helical spring effect; reduce Cable Bending Radius, avoid cable, because overbending swings, cable seal occurs and lost efficacy.
Description
Technical field
The utility model relates to the outlet box body of pump, specifically a kind of outlet box being provided with cable protecting device.
Background technology
In the process of mining, draining is an important problem always.Immersible pump obtains general application because it is easy to use.
At present, in daily transport with install and use in process, the cable of pump inside upwards passes outlet box body, and enter pump body from the connection gap of cable and outlet box body in order to anti-sealing, the contact-making surface of cable and outlet box body is provided with cable sealing ring, but, because cable stretches out after outlet box body without any auxiliary support apparatus, cause the bending radius of cable too small, and cable produces pull-out and loosening phenomenon under deadweight, make the link position generation seal failure of cable and outlet box body, cause motor entering water, submersible electric pump motor is caused to burn.
For this reason, architecture advances is carried out, to solve the seal failure problem that cable causes because of flexural oscillations to the cable of the immersible pump of existing structure and outlet box body position.
Summary of the invention
Technical assignment of the present utility model solves the deficiencies in the prior art, provides a kind of outlet box being provided with cable protecting device.
The utility model solves the technical scheme that its technical problem adopts:
Be provided with an outlet box for cable protecting device, comprise the cable of outlet box body and protruding outlet box body, the contact-making surface of described cable and outlet box body is provided with cable sealing ring, above described outlet box body, be also provided with cable protecting device;
Described cable protecting device comprises sealing gland and helical spring, the inwall of described sealing gland offers the screw thread matched with helical spring, and helical spring one end is by being threaded into sealing gland inside; The bottom of described sealing gland is fixedly connected with outlet box body;
Cable is from top to bottom successively through outlet box body, sealing gland, helical spring protruding.
Concrete, described sealing gland is fixedly connected with outlet box body bolt.
Concrete, described cable is fixedly connected with bottom sealing gland.
Concrete, be provided with sealing ring between described cable lateral surface and sealing gland bottom interior wall.
The beneficial effect that a kind of outlet box being provided with cable protecting device of the present utility model is compared with prior art produced is:
The utility model is reasonable in design, sealing gland and helical spring have been set up in the basis of existing structure, the bottom of sealing gland is fixedly connected with outlet box body, by helical spring one end by being threaded into sealing gland inside, then cable is allowed from top to bottom successively through outlet box body, sealing gland, helical spring is also protruding, the cable stretching out sealing gland is made effectively to be propped up overfill protection under helical spring effect, reduce the bending radius of cable, avoid cable overbending in pump moving process and swing the problem that the seal failure of cable seal place occurs, motor is effectively avoided to burn because of water inlet, increase the service life.
