Detailed description of the invention
For making those skilled in the art be better understood from the technical solution of the utility model, below in conjunction with the accompanying drawings
With detailed description of the invention, this utility model is elaborated.
As depicted in figs. 1 and 2, embodiment of the present utility model provides a kind of quick connector, and this is fast
Speed adapter is for being connected to the unthreaded hole 101 of part 100 to be measured, and this quick connector includes: cylinder body
10, mandrel 20, expansion set 30 and handle 40.Air-filled pore 11, air-filled pore 11 it is formed with on cylinder body 10
Lead to unthreaded hole 101 to fill pressed gas in unthreaded hole 101；Mandrel 20 is arranged in cylinder body 10, and core
One end of axle 20 is stretched out from the first end of cylinder body 10；Expansion set 30 is made up of deformable elastomeric material, swollen
Set 30 is set in mandrel 20 and stretches out the part outside cylinder body 10；Handle 40 is installed in the second end of cylinder body 10,
This handle 40 can directly or indirectly be connected with the other end of mandrel 20 to drive mandrel 20 at cylinder body 10
Axle moves up；And mandrel 20 stretches out one end of cylinder body 10 and is formed with the end of the first end with cylinder body 10
The First terrace 21 that face is relative, expansion set 30 is positioned at the first end of First terrace 21 and cylinder body 10
Between end face.Preferably, between the end face of expansion set 30 and cylinder body 10, the first pad 23 it is additionally provided with.
So, as it is shown in figure 1, when not operating handle 40, mandrel 20 stretches out the part of cylinder body 10 and swollen
Set 30 can freely stretch in the unthreaded hole 101 of part 100 to be measured, as in figure 2 it is shown, treat that expansion set 30 stretches into
After unthreaded hole 101, operating handle 40, under the effect of handle 40, mandrel 20 is to the second end of cylinder body 10
Time mobile, to end face, close to push against expansion set 30, expansion set 30 is compressed First terrace 21 in the axial direction,
Radially expand with swelling in unthreaded hole 101, and then realize being tightly connected with part 100 to be measured.
This utility model utilizes the feature of expansion set 30 elastic expansion to realize the unthreaded hole 101 with part 100 to be measured
Being tightly connected, its connected mode is ingenious, and simple in construction, easy to operate, favorable sealing property.
Can the structure of handle 40 that moves axially of band moving mandrel 20 and connected mode have multiple, in this reality
With in a novel preferred embodiment, handle 40 has a service portion and one be connected with service portion
Shank, service portion is articulated in the second end of cylinder body 10, and service portion has to pivoting centre different distance and
With the outer rim of the end abutment of cylinder body 10, when handle 40 rotates, different outer rims and end abutment are with band
Moving mandrel 20 moves axially.
In a preferred embodiment of the present utility model, quick connector also includes being threadedly connected at cylinder
The end cap 50 of the second end of body 10, the service portion of handle 40 is connected on end cap 50, and end cap 50 passes through
Rotating pushing and pressing handle 40 to move up at the axle of cylinder body 10, handle 40 band moving mandrel 20 is at cylinder body 10
Axle move up, thus regulate between the end face of the second end of First terrace 21 and cylinder body 10 away from
From, finally make the external diameter of expansion set 30 change in the range of certain size.The advantage of this structure is: behaviour
Before making handle 40, adjust expansion set 30 external diameter by rotating end cap 50, make expansion set 30 to be suitably inserted into
The unthreaded hole 101 of sizes series, and then increase the range of quick connector.
In a preferred embodiment of the present utility model, quick connector also includes being arranged on cylinder body 10
In piston 60, mandrel 20 threadeds with cylinder body 10 and coaxial with piston 60, and piston 60 passes through to draw
Bar 70 and handle 40 pivot joint, so, handle 40 drives piston 60 and mandrel 20 by pull bar 70
Move axially.Preferably, handle 40 is one-body molded with piston 60, and handle 40 is articulated in pull bar 70
End.
In a preferred embodiment of the present utility model, air-filled pore 11 is opened in along the radial direction of cylinder body 10
With the cylinder of cylinder body 10, and in cylinder body 10, form the gas cavity volume 12 connected with air-filled pore 11, and
The inside of mandrel 20 axially offers one end and connects with gas cavity volume 12 along it, the other end and unthreaded hole 101
The gas port 22 of connection, as preferably, gas cavity volume 12 is the ring surrounded with mandrel 20 by cylinder body 10
Describe chamber, and the two ends of ring-shaped chamber by piston 60 towards the end face of the first end of described cylinder body 10 and shape
Become in cylinder body 10 and the second step face 13 relative with the end face of the first end towards cylinder body 10 limits.
Quick connector of the present utility model has this ring-shaped chamber and is advantageous in that: make to enter this ring-shaped chamber
Pressed gas on the one hand enter unthreaded hole 101 by gas port 22 and think that part 100 to be measured is inflated, another
This pressed gas of aspect pushing and pressing piston 60 also band moving mandrel 20 moves towards the second end of cylinder body 10, Jin Erjin
One step improves the expansion set 30 swelling degree in unthreaded hole 101.
For making quick connector of the present utility model after part 100 to be measured is pulled down, mandrel 20 can be automatic
Reset, be additionally provided with in gas cavity volume 12 two ends respectively with the end face of the first end towards cylinder body 10 and
The spring 90 that second step face 13 abuts, it is preferable that set between spring 90 and second step face 13
Put the second pad 14.This spring 90 is in pressure when quick connector is tightly connected with part 100 to be measured
Contracting state, when pulling down from part 100 to be measured, spring 90 elastic recovery resets with band moving mandrel 20.
For preventing pressed gas in ring-shaped chamber between mandrel 20 and cylinder body 10 and piston 60 and cylinder
Gap between body 10 is flowed out, between mandrel 20 and cylinder body 10, between piston 60 and cylinder body 10
It is respectively provided with sealing ring 80.
Above example is only exemplary embodiment of the present utility model, is not used in restriction this utility model,
Protection domain of the present utility model is defined by the claims.Those skilled in the art can be new in this practicality
