Description
Technical field
The utility model belongs to the accessory technical field of reflux pump cylinder, and in particular to a kind of electricity for reflux pump cylinder
Cable lock sleeve.
Background technique
Reflux pump is usually fixedly installed in cylinder, therefore the cable of reflux pump needs the electricity outside barrel wall connection
Source, existing cabled manner are that mounting hole is opened up at the top of cylinder, and cable is directly through mounting hole, the cable of this structure
Gap between mounting hole is big, and cable can shake abrasion when operation, reduces the service life of cable.
For the fixed installation mode problem of pump housing cable, there is enterprise to make structure improvement, such as disclose (bulletin) number
A kind of submersible electric pump cable line terminal box sealing structure is disclosed for the utility model patent of CN202872540U, including wears and connects
In cable feedthrough and incoming seal circle on cable, incoming seal circle is set between cable and terminal box, compresses incoming seal
The cable feedthrough of circle is lock onto terminal box.Its structure novel, easy to process, production cost is low, and cable seal effect is good, can have
Effect has completely cut off moisture or humid air, solves the problems, such as that conventional seals are easy failure, increases the service life of diving electrical part.
But the incoming seal circle emphasis of this structure solves sealing waterproof problem, the deflection of incoming seal circle is very small, cable pressure
Lid is also without providing the deformation space of incoming seal circle, and cable wears difficulty, and installation is inconvenient.
Utility model content
The purpose of the utility model is to provide a kind of cable lock for reflux pump cylinder is fixed, the deformation of rubber sleeve is utilized
Locking cable is measured, cable is made not generate shaking and abrasion, cable long service life；The utility model has the advantages of convenient installation.
The utility model provides the following technical solution:
A kind of cable lock for reflux pump cylinder is fixed, is installed on the top of reflux pump cylinder, including gland, rubber sleeve
And nut, gland are connect with cylinder screw, the middle part in gland is equipped with a limited step, and rubber sleeve is set on limited step
Side, rubber sleeve top, which abuts, nut, and nut is tightened rear rubber sleeve with a deflection, and cable sequentially passes through gland, rubber
Gum cover and nut.Position-limiting action of the lower section of rubber sleeve by limited step, extruding of the top by nut, therefore elasticity occurs
Deformation, radial dimension becomes larger, to cable be wrapped up tight, makes seamless between cable and rubber sleeve, protects cable not shake, no
Easily it is worn.Rubber sleeve also applies reversed pressing force to nut, and the working environment for avoiding nut from being shaken is influenced and generated
The phenomenon that loosening.
It preferably, is gap between gland and rubber sleeve and cable and nut and cable under cable, free state
Cooperation, thus before locking cable, it can be rapidly fixed across this cable lock by cable, nut is then tightened again, makes rubber sleeve
It deforms and wraps cable, installation effectiveness is high.
It preferably, is also clearance fit between the rubber sleeve and limited step under free state, when rubber sleeve is squeezed buckling
After shape, the gap between rubber sleeve and limited step provides certain deformation space for rubber sleeve.
Preferably, a circle holding tank is also recessed on the inner wall of gland, holding tank is located at the top of limited step.Rubber sleeve
After compressing, holding tank is to provide bigger radial deformation space at the top of rubber sleeve, makes rubber sleeve that bigger elasticity occur
Deflection, so as to play good package effect.
Preferably, the compression piece of two arcs is additionally provided between the inner wall and cable of nut, two compression pieces are oppositely arranged.
Two compression pieces are inserted into gap after rubber sleeve holds cable tightly, then between nut and cable respectively, piece is compressed and increases
To the regular length in the axial direction of cable, cable is further protected, shakes it not.Two split type settings of compression piece are realized
It after cable is held tightly by rubber sleeve, then will successively compress between piece insertion nut and cable, not need to be inserted in from the end of cable
Piece is compressed, this structure is more convenient to install compared to the structure of whole section cascaded.
Preferably, the inner wall for compressing piece is equipped with several inclined latches with protruding above, and compression is fixed in the upper end of latch
On piece, the lower end of latch are inclined free end.Latch further applies radial pressing force to cable, prevents cable in nut
Interior shaking.The free end of latch can be moved by after the opposition of cable to the direction for compressing piece, therefore cargo handling process
In will not scrape damage cable outer wall.
The beneficial effects of the utility model are: squeezing rubber sleeve using nut, make rubber sleeve that compressive deformation occur, thus will
Cable is held tightly, therefore cable will not shake, and be not easy to be worn.It is clearance fit between cable and nut, rubber sleeve, it can
Quickly to pierce into cable, installation effectiveness is high.On gland and holding tank provides deformation space for rubber sleeve, and rubber sleeve is enable to send out
Raw bigger elastic deformation amount, to play good holding effect.It compresses piece and reciprocal latch structure is further enhanced to cable
Axial direction on regular length, shake cable not.
The utility model is good to the fixed effect of holding tightly of cable, easy for installation.
