Description

Inner thread connector
Technical field
The utility model relates to a kind of inner thread connector.
Background technique
At present, the seal with screwed joint of pipeline is screwed to connect by artificial hand substantially, and also needs in threaded connection place be wound around sealant tape or smear sealer, operation more complicated.Usually, the sealing be threaded of pipeline is temporary sealing, and after depressurization, the screw thread of this pipeline can be connected with other pipelines or valve, and owing to being wound with sealant tape or having smeared sealer, makes the very trouble of removing sealing change.For realizing quick connection and the dismounting of screw thread, application number is that the Chinese patent of CN201320896488 discloses a kind of internal thread quick connector, and this internal thread quick connector is connected and dismounting with the quick of internal thread by having the cooperation realization of externally threaded catch jacket and mandrel.Its working procedure is: first make mandrel end stretch out catch jacket, catch jacket shrinks, and now insert in internal thread by catch jacket, then mandrel end automatic retracted is in catch jacket, catch jacket expands under the effect of mandrel end, thus realizes being connected with the quick of internal thread; When disassembly is desired, make mandrel end again stretch out catch jacket, catch jacket shrinks again, is then extracted from internal thread by catch jacket, and then mandrel end automatic retracted is in catch jacket.
Drawn by the specification of above-mentioned patent and accompanying drawing analysis: stretch in the process of catch jacket at mandrel, the process that mandrel and catch jacket have a segment sync to move.That is: before catch jacket is stretched out in the end of mandrel, under the effect of the restoring force of piston supported spring, mandrel moves with identical speed with catch jacket, when contiguous block after piston and piston limit block are fitted, catch jacket stops suddenly, and mandrel continues motion and then stretches out catch jacket.
Catch jacket is unfavorable from moving to the motion mode internal threads quick connector stopped suddenly, because this motion mode of catch jacket is bound to, the related components of internal threads quick connector inside produces and impacts, thus affects its usability and working life.
Model utility content
For the above-mentioned technical problem that inner thread connector of the prior art exists, the utility model provides a kind of inner thread connector, there is the process of one section of asynchronous movement in the catch jacket in this inner thread connector and mandrel, thus make the velocity variations of catch jacket comparatively slow, improve inner thread connector usability and working life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of inner thread connector, comprises catch jacket and mandrel, also comprises:

Embodiment
For making those skilled in the art better understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, embodiment of the present utility model discloses a kind of inner thread connector, the catch jacket 20 of this inner thread connector is identical with core shaft structure with the catch jacket of inner thread connector of the prior art with mandrel 30, inner thread connector of the present utility model also comprises cylinder body 10, push rod 40, drive sleeve, cylinder body 10 offers center hole, center hole at least has the taper hole 62 of one section of first cylindrical hole, 61, one section of second cylindrical hole 63 and one section of connection first cylindrical hole 61 and the second cylindrical hole 63, and the aperture of the first cylindrical hole 61 is less than the aperture of the second cylindrical hole 63; Push rod 40 and drive sleeve are all arranged in center hole, and push rod 40 at least has a type conical bench 31, push rod 40 part stretches into one end of drive sleeve, and drive sleeve offers multiple cinclides along its circumference, be provided with steel ball 50 in each cinclides, and steel ball 50 is between push rod 40 and cylinder body 10; Catch jacket 20 is connected with the other end of drive sleeve, and mandrel 30 wears catch jacket 20, drive sleeve successively, and is connected with push rod 40.
When push rod 40 moves towards catch jacket 20 direction, type conical bench 31 forces steel ball 50 to move along the hole wall of the first cylindrical hole 61 and taper hole 62 successively, and when steel ball 50 moves to the hole wall of the second cylindrical hole 63, type conical bench 31 and steel ball 50 stagger.
When the type conical bench 31 of push rod 40 forces steel ball 50 to move along the hole wall of taper hole 62, steel ball 50 and push rod 40 create relative movement, and the direction of movement velocity v is for tilting upward, this movement velocity v resolves into a radial componental movement speed v 2 and an axial componental movement speed v 1, this axial componental movement speed v 1 is just the opposite with the direction of push rod 40 movement velocity, thus the movement velocity making steel ball 50 downward relative to the axis of cylinder body 10 reduces gradually, and finally when type conical bench 31 staggers with steel ball 50, the movement velocity of steel ball 50 is decreased to 0, and drive by steel ball 50 due to drive sleeve, drive sleeve and the movement velocity of catch jacket 20 driven by drive sleeve is also corresponding is decreased to 0 gradually, thus the correlated parts of the inside of whole inner thread connector can not be impacted.
From the above, due to the existence of type conical bench 31, when steel ball 50 slides at taper hole 62 place, push rod 40 and drive sleeve achieve asynchronous movement.
Cylinder body 10 can be one machine shaping, also can be shaping by multiple Assembly of the parts, in a preferred embodiment of the present utility model, cylinder body 10 comprises the upper cylinder half 11, middle cylinder 12 and the lower cylinder 13 that connect successively, center hole wears upper cylinder half 11, middle cylinder 12 and lower cylinder 13, and center hole is arranged in a section of cylinder 12 and has the first cylindrical hole 61, taper hole 62 and the second cylindrical hole 63.
Drive sleeve can be one-body molded, also can be shaping by multiple Assembly of the parts, in a preferred embodiment of the present utility model, and the reducing sleeve 72 that drive sleeve comprises lock sleeve 71, is socketed with lock sleeve 71; The end of catch jacket 20 and the endoporus clamping of reducing sleeve 72.
Be limited core spindle 30 play diametrically, and in a preferred embodiment of the present utility model, be also provided with centring sleeve 73 in the endoporus of reducing sleeve 72, mandrel 30 wears centring sleeve 73.Under the constraint of centring sleeve 73, mandrel 30 can not radial-play, and then improves the stationarity of mandrel 30 axial motion.
For making mandrel 30 reset in a free state, in a preferred embodiment of the present utility model, push rod 40 is also arranged with Returnning spring 90, the two ends of Returnning spring 90 abut with push rod 40 and drive sleeve respectively.Under the effect of Returnning spring 90, push rod 40 can be with moving mandrel 30 to move upward, thus makes in mandrel 30 end retraction catch jacket 20.
Further, centring sleeve 73 is arranged with holddown spring 100, the two ends of holddown spring 100 abut with lock sleeve 71 and catch jacket 20 to make reducing sleeve 72 and catch jacket 20 have certain pretightening force respectively.
For increasing the tightness of inner thread connector of the present utility model, in a preferred embodiment of the present utility model, sealed by seal ring 110 between drive sleeve and mandrel 30 and between drive sleeve and cylinder body 10.
For convenience of operation mandrel 30, in a preferred embodiment of the present utility model, cylinder body 10 is provided with handle 80 away from one end of catch jacket 20; When pressing handle 80, handle 80 pushes against push rod 40 and catch jacket 20 is stretched out in end with moving mandrel 30.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can in essence of the present utility model and protection domain, and make various amendment or equivalent replacement to the utility model, this amendment or equivalent replacement also should be considered as dropping in protection domain of the present utility model.
