Embodiment one:

Fig. 1 to Fig. 5 shows a preferred embodiment of this insertion pipe of the application, the insertion pipe conduct in the present embodiment The handle tube of dust catcher uses, and certainly, can also be used as the use of other pipe fittings, such as the scrubbing brush adapter tube of dust catcher --- it is used for Connect the hose adapter tube of handle tube and scrubbing brush or dust catcher --- for connecting handle tube and hose.It is inserted with tradition Taking over identical is that the insertion pipe also includes the first pipeline section 1, the second pipeline section 2, push-button socket 3, locking button 4 and locking spring 5 etc. Component.Wherein:

First pipeline section 1 and the second pipeline section 2 are two components of separate structure, and perforation opens up one on the tube wall of the first pipeline section 1 A dead bolt hole 101.In Fig. 1, the left end of the second pipeline section 2 is inserted in the right part of the first pipeline section 1, and the second pipeline section 2 is outer A locked groove 201 is offered on tube wall.

Push-button socket 3 is integrally attached on the outer tube wall of the first pipeline section 1, and hinge hole 301 is offered on push-button socket 3.This In embodiment, push-button socket 3 and the first pipeline section 1 are plastic material, and the two is an integrally-molded.

Locking button 4 is hinged on push-button socket 3 by the hinged shaft 401 penetrated in above-mentioned hinge hole 301, and locks button 4 include the lock tongue 402 to extend internally along the radial direction of the first pipeline section 1.Aforementioned hinged shaft 401 and locking button 4 are integrated knot Structure, the two are an integrally-molded.

Locking spring 5 is folded between locking button 4 and 1 outer tube wall of the first pipeline section (for pressure spring), thus to locking button 4 Apply elastic force.And the lock tongue 402 on button 4 is locked to pass through dead bolt hole 101 under elastic force effect and be caught in locked groove 201, The first pipeline section 1 of such realization is fixedly connected with the second pipeline section 2.

The key improvements of the present embodiment are: above-mentioned hinge hole 301 has is greater than hinge on the axis direction of the first pipeline section 1 The width dimensions (radial dimension in other words) of axis 401.

The lock tongue 402 has on the axis direction of the first pipeline section 1 close to the front end face 402a of the second pipeline section 2 and separate The rear end face 402b of second pipeline section 2, the dead bolt hole 101 have on the axis direction of the first pipeline section 1 close to the second pipeline section 2 The rear wall surface of the hole 101b of preceding wall surface of the hole 101a and separate second pipeline section 2, and dead bolt hole 101 has the axis in the first pipeline section 1 It is greater than the width dimensions of lock tongue 402 on direction.

It refers again to shown in Fig. 1 to Fig. 5, in the second pipeline section 2 just the first pipeline section 1 of insertion and lock tongue 402 is embedded in locked groove When 201, the lock tongue 402 locking button 4 and locking on button is being schemed due to the Friction thrust by 2 outer tube wall of the second pipeline section acts on Limit on the left position (left part that hinged shaft 401 is located at hinge hole 301) is moved in 2, at this time the front end face 402a of lock tongue 402 and lock The preceding wall surface of the hole 101a of tongue apertures 101 is spaced apart, the interference of the two without motion, can freely turn if locking button 4 is pressed It is dynamic.When the second pipeline section 2 is acted on by pulling force F to the right in Fig. 2, the left side cell wall of locked groove 201 will be pushed on the second pipeline section 2 Locking button 4 and the lock tongue 402 locked on button move right (hinged shaft 401 moves right relative to hinge hole 301).Work as lock tongue After 402 front end face 402a moves right to the preceding wall surface of the hole 101a with dead bolt hole 101 to contact, lock tongue 402 can not continue the right side It moves.The preceding wall surface of the hole 101a of dead bolt hole 101 and the front end face 402a of lock tongue 402 mutually compress interference at this time, even if lock tongue 402 by Very big pulling force to the right is arrived, however wall surface of the hole 101a is locked under the movement interference effect of lock tongue 402 before dead bolt hole 101 Tongue 402 can not be detached from outward locked groove 201 along the radial direction of the first pipeline section 1, then the second pipeline section 2 also just can not be from the first pipe It is detached from section 1.In this case, if necessary to the second pipeline section 2 of release, then eliminating aforementioned pulling force F to the right, pressing lock first The left part of tight button 4 rotates counterclockwise locking button 4 around hinged shaft 401, locks button 4 at the same time relative to the first pipeline section 1 is moved to the left certain distance (the second pipeline section 2 can also be moved to left a small distance by the active force of locking button 4), so that lock Tongue 402 is detached from locked groove 201, and the second pipeline section 2 can be extracted out to the right.

It refers again to shown in Fig. 4 and Fig. 5, in the present embodiment, when hinged shaft 401 is moved to limit on the left position in hinge hole 301 When setting, the distance between preceding wall surface of the hole 101a and the front end face 402a of lock tongue 402 of dead bolt hole 101 L2 are less than or equal to the hinge Meet the difference L1 of the width dimensions of hole 301 and the hinged shaft 401.So certifiable hinged shaft 401 can have enough in hinge hole 301 Big axial displacement (in this application, unless otherwise instructed, described " axial direction " is with the first pipeline section 1 for reference), from And when the second pipeline section 2 is acted on by pulling force F to the right, the front end face 402a of lock tongue 402 can be with the preceding hole wall of dead bolt hole 101 Face 101a comes into full contact with.

In the present embodiment, on the axial direction of above-mentioned first pipeline section 1, hinged shaft 401 is than lock tongue 402 farther away from the second pipe Section 2.That is the front end (close to that one end of the second pipeline section) that locking button 4 is arranged in of lock tongue 402, user presses locking when use The rear end of button 4 is so more bonded the operating habit of user, more meets ergonomics to discharge the second pipeline section 2.

In this application, unless otherwise instructed, described " far from the second pipeline section ", " close to the second pipeline section " are respectively Refer in Fig. 1 " right part far from the second pipeline section ", " close to the right part of the second pipeline section ".

In the present embodiment, the front end face 402a of above-mentioned lock tongue 402 includes matching with the preceding wall surface of the hole 101a of dead bolt hole 101 Inclined plane part.The inclined plane part has outboard end in the first pipeline section 1 in the radial direction far from 1 central axes of the first pipeline section and leans on The inner end of nearly first pipeline section, 1 central axes, and on the axis direction of the first pipeline section 1, the inner end is than the outboard end Closer to the second pipeline section 2.It can be appreciated that the front end face 402a structure of lock tongue 402 is arranged such, dead bolt hole can further improve 101 preceding wall surface of the hole 101a hinders shifting ability to lock tongue 402.

Further, the preceding wall surface of the hole 101a of the dead bolt hole 101 is adapted with the inclined plane part of above-mentioned front end face 402a Inclined-plane.

Specific address, the preceding wall surface of the hole 101a of dead bolt hole 101 are inclined-plane, which has in the axis side of dead bolt hole 101 It is upwardly away from the outboard end of 1 central axes of the first pipeline section and the inner end close to 1 central axes of the first pipeline section, and in the first pipeline section 1 Axis direction on, the inner end than the outboard end closer to the second pipeline section 2.

Obviously, the preceding wall surface of the hole 101a of tongue apertures 101 is also possible to the vertical plane perpendicular to 1 central axes of the first pipeline section, even It can be the back slope opposite with above-mentioned inclined-plane inclined direction, it is same to have prevention lock tongue 402 along 1 radial direction of the first pipeline section The function being displaced outwardly.But when bevel structure that the preceding wall surface of the hole 101a setup cost embodiment of tongue apertures 101 is this, to lock It is stronger that tongue 402 hinders shifting effect.Institute it should be noted that, if the preceding wall surface of the hole 101a of tongue apertures 101 be arranged to and above-mentioned inclined-plane tilt Contrary back slope, then the tilt angle of the back slope should not be too large, to prevent lock tongue 402 from making in thrust to the right Get over the back slope easily under and at shifting outside locked groove 201.

Shifting effect is hindered to lock tongue 402 in order to further strengthen, we can also consolidate on the outer tube wall of the first pipeline section 1 Fixed setting, the block at 101 hole of dead bolt hole.And on the axis direction of the first pipeline section 1, block more than lock tongue 402 Close to the second pipeline section 2, block has the blocking surface matched with the front end face 402a of lock tongue 402, while in the axis of the first pipeline section 1 On line direction, the blocking surface than dead bolt hole 101 preceding wall surface of the hole 101a farther away from the second pipeline section 2.

It can be appreciated that the preceding wall surface of the hole 101a effect having the same of the blocking surface of above-mentioned block and dead bolt hole 101, is In order to prevent being moved radially outward for lock tongue 402.

Embodiment two:

Fig. 6 to Fig. 9 shows another specific embodiment of this insertion pipe of the application, in the present embodiment the insertion pipe with The structure of insertion pipe is essentially identical in above-described embodiment one, and unique difference is: in the present embodiment, when hinged shaft 401 is hinged When in hole 301 to limit on the left position, the preceding wall surface of the hole 101a of dead bolt hole 101 and the distance between the front end face 402a of lock tongue 402 L2 is greater than the difference L1 of the width dimensions of hinge hole 301 and hinged shaft 401.Namely the preceding wall surface of the hole 101a of dead bolt hole 101 and lock in Fig. 8 The distance between the front end face 402a of tongue 402 is bigger.

It refers again to shown in Fig. 6 to Fig. 9, when the second pipeline section 2 in Fig. 6 is acted on by pulling force F to the right, the second pipeline section 2 The left side cell wall of upper locked groove 201 will push locking button 4 and the lock tongue 402 locked on button to move right.When 401 phase of hinged shaft When moving right hinge hole 301 to limit on the right-right-hand limit position, because of the position-limiting action by 301 hole wall of hinge hole, lock button 4 and Lock tongue 402 on locking button 4 can not continue to move to right, at this time the preceding wall surface of the hole of the front end face 402a of lock tongue 402 and dead bolt hole 101 For 101a there are biggish gap, which is L2.If aforementioned pulling force F is still maintained, then lock tongue 402 can be in locked groove 201 It is rotated counterclockwise under the thrust of left side cell wall around hinged shaft 401, after the front end face 402a of lock tongue 402 turns an angle It will be in contact with the preceding wall surface of the hole 101a of dead bolt hole 101, the preceding wall surface of the hole 101a of dead bolt hole 101 prevents lock tongue 402 from continuing to turn It is dynamic, lock tongue 402 can not completely disengage locked groove 201 (rotated counterclockwise certain angle around hinged shaft 401 because of lock tongue 402 at this time, so It can have certain gap, such as Fig. 9 between 201 bottom wall of locked groove), the second pipeline section 2 can not equally be extracted out to the right.

Certainly, above-described embodiment is only the technical concepts and features for illustrating the application, and its object is to make people much of that Solution present context is simultaneously implemented accordingly, and the protection scope of the application can not be limited with this.It is all according to the application major technique The equivalent transformation or modification that the Spirit Essence of scheme is done should all be covered within the scope of protection of this application.
