Description
Technical field
The present invention relates to oil drilling cementing technology field, particularly relate to a kind of anti-lost joint of fast self-locking.
Background technology
Helicoid hydraulic motor is a kind of drilling dynamics instrument, is the energy conversion that can be converted to mechanical energy of the pressure of a kind of liquid
Device, also referred to as positive displacement motor, be one of downhole tool conventional in current drilling engineering, be also most widely used one
Well dynamic instrument.Helicoid hydraulic motor is mainly made up of bypass valve, stator, rotor, universal drive shaft assembly, driving-shaft assembly etc..Screw rod
The upper anti-drop structure of drilling tool is currently by threaded, once helicoid hydraulic motor generation housing crack conditions, and anti-lost parts play anti-
Fall effect, in some cases because phenomenon of rupture finds not in time, often result in anti-lost parts herein and produce de-mouth
Phenomenon.
Summary of the invention
It is an object of the invention to overcome the deficiency of above-mentioned technology, and a kind of anti-lost joint of fast self-locking is provided, substitute spiral shell
Stricture of vagina connects, and prevents screw rod from rupturing.
The present invention for achieving the above object, by the following technical solutions:
A kind of anti-lost joint of fast self-locking, it is characterised in that: include compressing locknut, clamping sleeve, spring, steel ball, anti-lost nut, preventing
Fall connecting rod；The ring week of described anti-lost connecting rod is provided with steel-ball groove, enters described in steel ball shoulder hole from described anti-lost nut
Anti-lost connecting rod and described anti-lost nut check, described clamping sleeve is enclosed within described anti-lost nut and is blocked by described shoulder hole, described
Compressing locknut and be fixed on the end of described anti-lost nut, described spring is placed between described compression locknut and described clamping sleeve.This
Structure is easy for installation, the lifting that general safety obtains.After changing to this structure, anti-lost connecting rod can play anti-lost effect
Time, connecting rod can rotate freely in inside, thoroughly stops out phenomenon.
Preferably, the front end of described anti-lost nut is provided with baffle plate, and the side of the right-hand member of described clamping sleeve and described baffle plate is joined
Close.
Preferably, the inner circumference outside described clamping sleeve is provided with spring groove, and it is anti-lost with described that described spring is placed in spring groove
Between nut.
The invention has the beneficial effects as follows: compared with prior art, this structure is easy for installation, the lifting that general safety obtains.
After changing to this structure, anti-lost connecting rod can be playing anti-lost effect when, and connecting rod can rotate freely in inside, thoroughly
Stop out phenomenon.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and preferred embodiment describe in detail the present invention detailed description of the invention.Such as Fig. 1 and shown, a kind of
The anti-lost joint of fast self-locking, including compressing locknut 1, clamping sleeve 2, spring 3, steel ball 4, anti-lost nut 5, anti-lost connecting rod 6；Described anti-
The ring week falling connecting rod is provided with steel-ball groove 7, enters described anti-lost connecting rod and institute in steel ball shoulder hole 8 from described anti-lost nut
Stating anti-lost nut check, described clamping sleeve is enclosed within described anti-lost nut and is blocked by described shoulder hole, and described compression locknut is fixed
At the end of described anti-lost nut, described spring is placed between described compression locknut and described clamping sleeve.Spring is given all the time and is compressed
Overlap a power to the right so that clamping sleeve covers all the time above steel ball, prevents steel ball from ejecting.8 ladders are had on anti-lost nut
Hole, places 8 steel balls respectively, plays one and be similar to the rotary self-locking structure that bearing is the same.This structure is easy for installation, overall peace
The lifting entirely obtained.After changing to this structure, anti-lost connecting rod can be playing anti-lost effect when, and connecting rod can be in inside
Rotate freely, thoroughly stop out phenomenon.
In order to carry out spacing to clamping sleeve, the front end of described anti-lost nut is provided with baffle plate 9, the right-hand member of described clamping sleeve
Coordinate with the side of described baffle plate.
Cruelly leaking outside in order to avoid spring, the inner circumference outside described clamping sleeve is provided with spring groove 10, and described spring is placed in
Between spring groove and described anti-lost nut.
This structure is easy for installation, the lifting that general safety obtains.After changing to this structure, anti-lost connecting rod can play
The when of anti-lost effect, connecting rod can rotate freely in inside, thoroughly stops out phenomenon.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should
It is considered as protection scope of the present invention.
