Description

A kind of switch knob preventing control line fracture, being wound around

Technical field

This utility model relates to field of mechanical technique, a kind of prevent control line fracture, be wound around Switch knob.

Background technology

More existing welding guns, the local welding gun at some corner needs the anglec of rotation to be welded by soldering tip alignment Point, but angle one rotates, be originally fixed on its handle body be located in switch cover by compressing switch also Rotating with, the most inconvenient operator are by compressing switch.Therefore, switch cover and handle are devised after The structure that this physical ability rotates against, facilitates operator by compressing switch.

But it is found that a problem after this design.Its thread switching control is directly from handle body end Opening position cabling, namely thread switching control and handle body be not fixed together.Therefore, when outside switch When lid is rotated at random, thread switching control is not owing to fixing, so being easy to be wrapped on handle body, even Cause situation about being broken from switch by thread switching control.

To this end, some people directly uses binding to be tightened on the outer wall of handle body by thread switching control, but The most unsightly.Some are also had directly to use glue to be bonded on handle body by thread switching control, but glue Insecure, thread switching control is still easy to be torn off, and has potential safety hazard, and the use to whole product limits Bigger.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, uses fastening structure by firm with handle for switch Admittedly be fixed together, and can prevent by thread switching control from switch shut down.

For achieving the above object, a kind of switch knob preventing control line fracture, being wound around is designed, including handle Body, switch, thread switching control, switch cover, connecing of one end connecting valve of described thread switching control Line end, described switch is placed in switch cover and the spatia between handle body, it is characterised in that: Described thread switching control at least local uses fastening structure to be fastened on handle body.

Described fastening structure includes handle external screw thread, the lock sleeve being located on the outer wall of handle body；Described Handle external screw thread on be provided with wire casing along handle body length direction；Described lock sleeve is at least provided with lock sleeve Female thread, the thread switching control at handle external screw thread embeds in wire casing, lock sleeve female thread spiral shell outer with handle again Stricture of vagina is threaded；Described handle external screw thread is located at the tail end of handle body or close to handle body tail end Place.

Described fastening structure is included on handle body and sets cable hole, and the inwall of the tail end at handle body On set handle female thread, on described handle female thread, the length direction along handle body is provided with another wire casing, The tail end of thread switching control through this cable hole laggard enter in handle body, be positioned at the switch at handle female thread Control line embeds in another wire casing, one be provided with locking externally threaded retaining ring threaded with handle female thread general Thread switching control is anchored on handle body.

Described fastening structure is included on handle body and sets cable hole, and the inwall of the tail end at handle body On set and take out bridge, the tail end of thread switching control sequentially passes through described cable hole, takes out the bridge opening of bridge, is positioned at and takes out bridge The thread switching control of entrance point is equipped with tieing, and the size of described tieing is more than the size of the bridge opening taking out bridge.

Described lock sleeve uses annular or uses cylindric or use cone cylinder shape.

When lock sleeve uses annular, lock sleeve female thread is located at the inwall of lock sleeve, and the outer wall of lock sleeve is also It is provided with lock sleeve external screw thread；When using cylindrical shape or cone cylinder shape, lock sleeve female thread is located at lock sleeve One end, the other end of lock sleeve sets another lock sleeve female thread or lock sleeve external screw thread.

When described handle external screw thread is located at the tail end close to handle body, the tail end of handle body is until hands It is provided with gap at the externally threaded wire casing of handle.

Being additionally provided with heavy string holes on handle body, described heavy string holes is between switch and wire casing, and heavy string holes Termination through with the termination of wire casing.

The outer wall of the tail end of described handle body is provided with handle external screw thread.

This utility model compared with the existing technology, solves thread switching control easily by asking of tearing off on switch Topic；Meanwhile, improve the risk that original thread switching control and leader cable are prone to be intertwined, be also prevented from Thread switching control is due to fixing and rotate the wear problem brought；And better appearance in appearance.
