And boss abuts the opposite side of locking column；And when fastener is in unlocked position, pushes or pulls to rod and cause
Inner tube is slided relative to exterior tube, and second in described two juts passes through between boss.
Therefore, when fastener is in the locked position and thrust or pulling force are applied to rod, first connecting portion is in fastener
On power resisted by boss.Pivot between fastener and exterior tube is thus without the whole sizes for bearing applying power.
As a result, less pivot can be used, and it will surrender in the case where the applying power of whole range is born.
When fastener is applied to rod in unlocked position, and thrust or pulling force, inner tube is slided relative to exterior tube,
And described second in two juts passes through between two boss.Pass through between boss by with second connecting portion
Configuration, boss can be positioned at the height similar to first connecting portion.This then have have an advantage that, when fastener exists
When latched position and thrust or pulling force are applied to rod, by boss be applied to fastener power will with first connecting portion apply
The similar position of power.As a result, fastener undergoes less moment of torsion, and thus more will not when thrust or pulling force apply pivot
Turn.
Inner tube may include planar section, and the jut is from the planar section projection, and planar section is than jut
It is wider so that planar section extends along the both sides of each jut.This then has and has an advantage that the boss of exterior tube can be with
Be positioned in the way of relative compact with the same or similar height of jut.Especially, exterior tube can have internal diameter, and it is only
Slightly larger than the external diameter of inner tube, in order to allow sliding motion.Flat surfaces on inner tube top are in being to provide for outside
The space of the jut of pipe.
Inner tube can have shape of cross section, its main sector for corresponding to circle or ellipse, and flat surfaces may correspond to master
Fan-shaped string.Additionally, exterior tube can have the shape of cross section of circular or ellipse.
Fastener can be pivoted around the pivotal point being positioned above jut.This then has the card for haveing an advantage that relative compact
Fastener can be used.In the case of no boss, torque or moment of torsion can be applied in buckle in response to thrust or pulling force
On part.The moment of torsion will then cause that fastener is pivoted up or down, and it may be such that fastener blocks or move to unlocked positioning
Put.By using the configuration that second connecting portion is passed through between two boss, the resulting net force applied by boss can have dashes forward with first
The similar position of power that the portion of rising applies.As a result, fastener undergoes less moment of torsion in response to the power of applying.It is possible thereby to position
Pivotal point is stuck in latched position or moves to unlocked position above jut without worry fastener.

Pivot of the result between fastener and exterior tube need not bear thrust or pulling force.
When fastener is applied to rod in unlocked position, and thrust or pulling force, inner tube can be slided relative to exterior tube
Move, and first connecting portion can pass through between another boss.By matching somebody with somebody for passing through between another boss with first connecting portion
Put, another boss can be positioned at the height similar to second connecting portion.This then have have an advantage that, when fastener exists
Latched position and when thrust is applied to rod, the power for being applied to fastener by another boss will have and second connecting portion applies
The similar position of power.As a result, fastener undergoes less moment of torsion, and thus more will not unexpectedly be moved to when pulling force applies
Unlocked position.
When fastener is in latched position and when thrust or pulling force are applied to rod, first connecting portion may be considered that applying
First power is to locking column, and boss may be considered that the second power of applying to locking column.Second power can be equal to the first power and direction phase
Instead, and with the first power identical position.As a result, pivot need not bear the power of any applying.Additionally, without moment of torsion quilt
It is applied on fastener, and thus fastener can't be pivoted in response to the power for applying.
Present invention also offers a kind of telescopic rod for vacuum cleaner, including inner tube, exterior tube and fastener,

Specific embodiment
The telescopic rod 1 of Fig. 1 to 8 includes inner tube 2, exterior tube 3 and snap component 4.
Inner tube 2 is the shape of substantial cylindrical.However, the top of pipe 2 includes planar section 20.As a result inner tube has
Such shape of cross section, it limits planar section 20 similar to round big sector, the wherein big fan-shaped string.Inner tube 2 is wrapped
Include multiple juts 21, its from planar section 20 upwardly.Gap limits recess 22 between each pair jut 21, wherein
The locking column 44 of snap component 4 is protruded into the gap；This is described in greater detail below.The first end of inner tube 2 can be attached
Cleaning head or annex (not shown) are connected to, and the second opposed end of inner tube 2 is received in exterior tube 3.Inner tube 2 along
Longitudinal axis 23 is slided relative to exterior tube 23, and seal 24 is provided at the second end of inner tube 2 in order to minimum
Change sealing internally between pipe 2 and exterior tube 3.
Exterior tube 3 is cylinder form.The first end of exterior tube 3 is around inner tube 2, and the second opposed end is attachable
To handle or flexible pipe (not shown).Opening 31 is formed in the top of exterior tube 3, and is positioned near the first end of pipe 3.Outward
Portion's pipe 3 includes a pair of the lugs 32 being positioned on the opposite side of opening 31, and a stop for end for being positioned at opening 31
Part 33.As described below, lug 32 is used as the fulcrum for snap component 4, and retainer 33 is used to limit the fortune of each component 4
It is dynamic.Exterior tube 3 also includes a pair of forward lands 34 and a pair of aft lands 35.Forward land 34 is positioned at the lock of snap component 4
The front of fixed column 44, and aft land 34 is positioned at the rear of locking column 44.Additionally, each pair boss 34,35 is positioned at jut
On 21 opposite side.Therefore, when inner tube 2 is slided relative to exterior tube 3, jut 21 is between forward land 34 and rear portion
Pass through between boss 35.As described below, when thrust or pulling force are applied to rod 1, boss 34,35 is used to resist by jut 21
It is applied to the power of locking column 44.
The snap component 4 includes fastener 41 and spring 42.
Fastener 41 is integral type body portion, and it includes button 43 and locking column 44.Fastener 41 is being positioned at the He of button 43
Exterior tube 3 is pivotally mounted at pivotal point 45 between locking column 44.More particularly, fastener 41 includes a pair of recesses 46,
It is positioned on the opposite side of fastener 41.The lug 32 of exterior tube 3, its is substantially rectangular shape, is seated in recess 46 and uses
Act on the fulcrum of fastener 41.
Spring 42 is leaf spring, its downside for being fixed to fastener 41 at one end, and outside is fixed at opposed end
The inner side of pipe 3.Spring 42 is biased power to fastener, and by locking column 44, downwardly inner tube 2 is pushed away for it.
Fastener 41 is pivoted between latched position (Fig. 5) and unlocked position (Fig. 6).Fastener 41 is biased by spring 42
To latched position.When fastener 41 is in latched position, locking column 44 is protruded between two juts 21 of pipe 2 internally
In recess 22.Inner tube 2 is then prevented from relative to the motion of exterior tube 3.Especially, when inner tube 2 moves leftwards and rightwards, lock
One in the abutment lug portion 21 of fixed column 44, in order to prevent any further motion.Fastener 41 is transported by pressing button 43
Move unlocked position.When button 43 is depressed, fastener 41 overcomes the biasing force of spring 42 to be pivoted around pivotal point 45.Knot
Really, locking column 44 is pivoted up.Locking column 44 then lifts off recess 22 and jut 21.Inner tube 2 is then able to freedom
Ground horizontally slips relative to exterior tube 3.When button 43 discharges, spring 42 is by locking column biased downward.Depending on inner tube 2
Position, locking column 44 is biased into recess 22 or in jut 21.In former case, fastener 41
Return to latched position.In latter case, locking column 44 jut 21 slide on top until locking column more than 44 one it is recessed
Portion 22 aligns and is snapped into the recess, and fastener 41 returns to latched position at this point.
As it can be seen in figures 5 and 6, the retainer 33 of exterior tube 3 limits both motions up and down of fastener 41.Work as button
43 are depressed and when locking column 44 is pivoted up, when locking column 44 crosses jut 21 under the adjoining of locking column 44 retainer 33
Side.Thus the further downward stroke of button 43 is prevented from, and user is provided the instruction that fastener 41 is in unlocked position.
When button 43 be released and spring 42 by 44 biased downward of locking column when, when fastener 41 is flushed with exterior tube 3, fastener 41
The top of adjacent retainer 33.Therefore, although during when fastener 41, locking column 44 protrudes into recess 22 in latched position when,
Small―gap suture is still suffered between the top of locking column 44 and inner tube 2.It is position that exterior tube 3 is flushed by the way that fastener 41 is stopped
Place is put, is flushed with exterior tube 3 when fastener 41 is in latched position.This then have have an advantage that fastener 41 in use not
Unexpectedly can be hooked on article, for example in home decoration or curtain.
More detailed description will be provided now to illustrate to be applied in latched position and thrust or pulling force when fastener 41
During rod 1, the interaction occurred between fastener 41, inner tube 2 and exterior tube 3.Thrust or pulling force are to promote inner tube 2 relative
In the power that exterior tube 3 is moved along longitudinal axis 23.Then edge promotes inner tube 2 to be acted on towards the direction that exterior tube 3 is moved to thrust,
And pulling force is acted on along the direction for promoting inner tube to move from exterior tube 3.So as to when fastener 41 is in unlocked position and thrust
When being applied to rod 1, inner tube 2 and exterior tube 3 be brought together after and rod 1 Length Contraction.Conversely, when fastener 41 is unlocked
Positioning is put and when pulling force is applied to rod 1, inner tube 2 and exterior tube 3 is separated and the length of rod 1 expands.
Fig. 7 and 8 shows rod 1 of the fastener 41 in latched position.Locking column 44 protrudes into the first projection of pipe 2 internally
In recess 22 between portion 21a and second connecting portion 21b.
When thrust is applied to rod 1, inner tube 2 is moved relative to inner tube 3 and fastener 41 along towards right direction.The
One jut 21a then abuts the first sidepiece 47 of locking column 44, and applies the first power to locking column 44.In fastener 41 and outward
There is a certain degree of pivot play between portion's pipe 3；That is exterior tube 3 lug 32 engagement fastener 41 in recess
Before 46 wall, fastener 41 freely can turn one in a small amount (referring to Fig. 7) with Thuban to the left relative to exterior tube 3.Therefore, respond
In the first power, fastener 41 is moved relative to exterior tube 3 along towards right direction.Aft land 35 then abuts locking column 44
The second opposite side portion 48, and apply the second power to locking column 44.Second power is equal to the first power and in opposite direction, and with the
One power identical position.As a result, the further motion to the right of inner tube 2 is prevented from.
When pulling force is applied to rod 1, inner tube 2 is moved relative to inner tube 3 and fastener 41 along towards left direction.The
Two jut 21b then abut the second sidepiece 48 of locking column 44, and apply the 3rd power to locking column 44.Due in fastener 41
A certain degree of pivot play and exterior tube 3 between, the 3rd power causes that fastener 41 is transported relative to exterior tube 3 along left direction
It is dynamic.Forward land 34 then abuts the first sidepiece 47 of locking column 44, and applies the 4th power to locking column 44.4th power is equal to the
Three power and in opposite direction, and with the 3rd power identical position.As a result, the further motion to the left of inner tube 2 is prevented from.
No matter whether pulling force or thrust are applied to rod 1, and boss 34,35 applies force to locking column 44, the power with by inner tube 2
The power that applies of jut 21 it is equal and in opposite direction, and with identical position.Result fastener 41 and exterior tube 3 it
Between pivot need not bear thrust or pulling force.It is possible thereby to use the pivot that will be surrendered in the case of pulling force or thrust is born.
Boss 34,35 applies the power with position identical with the power that jut 21 applies.This can by by boss 34,
35 are positioned on the opposite side of jut 21 and to be substantially the same highly place with jut 21 and become possibility.Position in this way
Boss 34,35 as a result, when fastener 41 is applied to rod 1 in unlocked position and thrust or pulling force, jut 21 exists
Pass through between boss 34,35.
Fastener 41 is pivoted relative to exterior tube 3 at point 45, and the point location is in the top of jut 21.Therefore, if convex
Platform 34,35 is ignored and pivot is designed to withstand the power of applying, by exterior tube 3 be applied to fastener 41 power will with by
Jut 21 is applied to the different position of power of fastener 41.Especially, having the power that exterior tube 3 applies will have work higher
Use line.As a result torque or moment of torsion are applied to fastener 41.The moment of torsion is pivoted in being so that locking column 44 downward or upward, is depended on
In apply power be thrust or pulling force.The retainer 33 of exterior tube 3 will prevent locking column 44 from pivoting downwards.However, locking column
44 can overcome the biasing force of spring 42 to be pivoted up.If applied to the power of rod 1 is sufficiently strong, fastener 41 can move to non-locking
Position.By providing boss 34,35, no moment of torsion is applied on fastener 41.As a result, the pivotal point 45 of fastener 41 can be with
It is positioned on jut 21, and without worrying that fastener 41 unexpectedly moves to unlocked position.
Due to the size and geometric error of rod 1, the power applied by jut 21 and boss 34,35 may not have complete phase
Same position.Therefore, when thrust or pulling force are applied to rod 1, moment of torsion may be applied on fastener 41.However, any
Moment of torsion all will be relatively small.Therefore, even if the power for applying is relatively strong, the moment of torsion for obtaining will be not enough to move fastener 41
To unlocked position.
Inner tube 3 has planar section 20, and jut 21 is from its projection.Planar section 20 is then more wider than jut 21,
So that planar section extends along the both sides of each jut 21.This then can with the boss 34,35 for haveing an advantage that exterior tube 3
Be positioned in the way of relative compact with the identical height of jut 21.Especially, exterior tube 3 can have internal diameter, and it is only
Slightly larger than the external diameter of inner tube 2, in order to allow sliding motion.Planar section 20 on the top of inner tube 2 in be to provide for
The space of the jut 34,35 of exterior tube 3.
Although exterior tube 3 has forward land 34 and aft land 35, significant benefit can be anterior convex by only having
Platform 34 or aft land 35 are realized.For example, when rod 1 be used to manipulate cleaning head on the ground, the thrust for being applied to rod 1 is led to
Often greater than pulling force.But being provided in for aft land 35 is so that can bear smaller pulling force will bear compared with high thrust
In the case of the pivot in region can be used.Used as another example, pivot can be used as bearing both pulling force and thrust.Before
Portion's boss 34 in can be to be provided, in order to prevent fastener 41 from surprisingly being transported when relatively strong pulling force is applied to rod 1
Move unlocked position.
Inner tube 3 has multiple recesses 22, and the locking column 44 of fastener 41 can be protruded into the recess 22.This then has
It is helpful that to be the height that can be used according to user or intention of the length of rod 1 adjust.However, being envisaged that inner tube 3 can be with
Including the single recess 22 being positioned between single pair of jut 21.Locking column 44 will then protrude into recessed when rod 1 is fully extended
In portion 22.One in only this pair jut 21 then will be traveling in forward land when internally pipe 2 is slided relative to exterior tube 3
Between 34 and aft land 35；And another in this pair of jut 21 will be extended only through between aft land 35.
