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, preferred embodiment of the present utility model provides a kind of quick connector, this quick connector for connecting the optical axis 100 with endoporus, to fill pressed gas in its endoporus.This quick connector comprises cylinder body 10, sealed adapter sleeve 30 and piston 20.The first end of cylinder body 10 offers main gas charge hole 11, and when optical axis 100 accesses, main gas charge hole 11 is communicated with the endoporus of optical axis 100 to fill pressed gas in inward hole; Sealed adapter sleeve 30 is for for optical axis 100 grafting, and sealed adapter sleeve 30 is made up of elastic material, and is installed in the second end of cylinder body 10, and housing structure need limit sealed adapter sleeve 30 entirety moves axially; Piston 20 is installed in cylinder body 10, and is positioned at the side of sealed adapter sleeve 30, and this piston 20 can sliding axially along cylinder body 10, and when moving to sealed adapter sleeve 30 side, piston 20 pushes sealed adapter sleeve 30.So, when sealed adapter sleeve 30 be not subject to piston 20 push time, the axial dimension t of sealed adapter sleeve 30 and the radial dimension d of its endoporus all do not change, and its endoporus arbitrarily can plug for optical axis 100; When sealed adapter sleeve 30 be subject to piston 20 push time, the axial dimension of sealed adapter sleeve 30 becomes t1 from t, and size diminishes, the radial dimension of its endoporus becomes d1 from d, size also diminishes, thus the hole wall of its endoporus is closely wrapped on optical axis 100, thus realizes being tightly connected.The patten's design that is tightly connected of the present utility model is ingenious, structure is simple, easy to operate, favorable sealing property.
Should be noted that: sealed adapter sleeve 30 is subject to piston 20 and pushes and the reason that the radial dimension of its endoporus diminishes is: sealed adapter sleeve 30 is in whole deformation process, solid volume remains unchanged, when the axial dimension of sealed adapter sleeve 30 diminishes, the section area of sealed adapter sleeve 30 can increase the reduction making up its axial dimension, and the external diameter of sealed adapter sleeve 30 remains unchanged, therefore, the diameter of bore of sealed adapter sleeve 30 reduces automatically.
The mode that promotion piston 20 slides at cylinder body 10 has multiple, as can machinery be adopted, pneumatic and mode of surging, for the pressed gas in gas tube can be utilized, in a preferred embodiment of the present utility model, piston 20 is promoted by aerodynamic force, particularly, second end of cylinder body 10 offers supplemental inflatable hole 12, piston 20 is led to away from sealed adapter sleeve 30 one end end face in this supplemental inflatable hole 12, this supplemental inflatable hole 12 is connected with gas tube, gas tube passes into pressed gas in supplemental inflatable hole 12, pressed gas promotes piston 20 and moves final pushing sealed adapter sleeve 30 to make its deformable seal connection optical axis 100 to the sealed adapter sleeve 30 being plugged with optical axis 100.
For improving maintainalbility and the interchangeability of quick connector, in a preferred embodiment of the present utility model, second end of quick connector installs an end cap 40, this end cap 40 is threaded with cylinder body 10 and passes through sealant sealing, and offer mounting hole 41 along the axis of end cap 40, this mounting hole 41 is formed towards the step surface of piston 20, and sealed adapter sleeve 30 is installed in mounting hole 41, and sealed adapter sleeve 30 is resisted against on step surface away from one end of piston 20.So, when piston 20 pushes sealed adapter sleeve 30 one end relative with piston 20, sealed adapter sleeve 30 is out of shape.
In a preferred embodiment of the present utility model, the inside of cylinder body 10 offers the first pilot hole 13, piston 20 slides along the first pilot hole 13, one end that piston 20 is relative with sealed adapter sleeve 30 arranges and pushes against axle 21, this pushing and pressing axle 21 part stretches in mounting hole 41, and moves to sealed adapter sleeve 30 under the drive of piston 20 and push sealed adapter sleeve 30 eventually through the end face pushing against axle 21.For prevent the two ends of sealed adapter sleeve 30 to be squeezed and occur destroy or wearing and tearing, at its two ends, pad 50 is all set.
For increasing the stability that piston 20 slides, at piston 20, one end of sealed adapter sleeve 30 is provided with the axis of guide 22, cylinder body 10 is offered the second pilot hole 14 and is stretched into for the axis of guide 22 and within it slide on the entity of the second end.So, piston 20 can smooth sliding under the guiding of the first pilot hole 13 and the second pilot hole 14.
After sealed adapter sleeve 30 is tightly connected optical axis 100, main gas charge hole 11 need be communicated with to fill pressed gas in inward hole with the endoporus of optical axis 100.In fact, main gas charge hole 11 can be made in several ways to be communicated with the endoporus of optical axis 100, and main gas charge hole 11 walking path also can have multiple, in a preferred embodiment of the present utility model, pushing and pressing axle 21, piston 20 and the axis of guide 22 are coaxially arranged, and the gas port 23 of through three is offered in the axis of three, this gas port 23 is communicated with the endoporus of main gas charge hole 11 and optical axis 100.The mode be communicated with by this gas port 23 makes processing simple, and the walking path of pressed gas in pilot hole is smooth and easy.
For increasing the sealing of quick connector inside, between piston 20 and cylinder body 10, pushing against and between axle 21 and end cap 40 and between the axis of guide 22 and cylinder body 10, O RunddichtringO 60 is set seals.
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.
