Abstract

The present invention relates to a structure modification of a locking mechanism of a telescopic pipe of a suction cleaner, which belongs to the technical field of household appliances. The universal telescopic pipe of a suction cleaner comprises at least two sections of telescopic inner and outer pipes which are mutually inserted and sheathed, and a locking mechanism is arranged between the inner and the outer pipes. The improvement is that one end of the inner pipe is provided with a spherical hinge head to form a spherical hinge pair with a spherical hinge sleeve, and arranged in the outer pipe of the spherical hinge sleeve. After the inner pipe is withdrawn from the outer pipe, an axial slope angle between the two pipes can be regulated according to requirements, and thus, the two pipes form an L shape. Thereby, the structure modification is conveniently for the operation of ground dust suction or overhang dust suction.

Description

Universal vacuum cleaner telescopic tube

Technical field

The present invention relates to a kind of dust catcher parts, especially a kind of architecture advances of dust collector expansion pipe belongs to household electrical appliance technical field.

Background technology

In order to satisfy the demand of existing dust catcher to the sweep-up pipe length adjustment, sweep-up pipe usually is made up of outer tube and the scalable interior pipe that is inserted into wherein, and retaining mechanism is housed between the inner and outer pipes.During use, after the pine oil retaining mechanism, pipe in can stretching as required, thus obtain suitable length, lock inner and outer pipes afterwards again.Retaining mechanism and associated inner and outer pipes structure are of a great variety, and its typical structure can be referring to related application files such as CN200510038703.4, CN200420079535.4, CN03221741.2.

The applicant finds, though various dust catchers are because the sweep-up pipe adjustable length, brought facility for user's conventional dust suction operation, yet, since sweep-up pipe axially can't form certain angle, therefore the subsides ground dust suction operation at the bottom of carrying out cupboard and so on or cupboard top and so on uphang the dust suction operation time, still can the other pin of other hand, have to bend over, on tiptoe, very inconvenience.

Summary of the invention

The present invention wants the technical solution problem to be: the shortcoming at above prior art exists, the conveniently adjusted universal vacuum cleaner telescopic tube of a kind of axial angle is proposed, thus all convenient smoothly to where carrying out the dust suction operation.

In order to solve above technical problem, universal vacuum cleaner telescopic tube of the present invention comprises the scalable inner and outer pipe of the mutual sleeve of two joints, between the described inner and outer pipe retaining mechanism is housed, its improvements are, an end of pipe is shaped on the ball pivot head in described, constitute the spherical hinge pair with the ball pivot cover, and be inserted in the outer tube by the ball pivot cover.It is recessed to be shaped on the location in described near the ball pivot head of pipe, and the control knob of described first retaining mechanism on the described outer tube is shaped on elongated end, and the termination of described elongated end is shaped on locator card.

Like this, in from outer tube, extracting out behind the pipe, can regulate axioversion angle between two pipes as required, make it to form " L " shape, thereby conveniently paste the ground dust suction or uphang dust suction and operate by the spherical hinge structure.During operation, when passing through control knob pine oil retaining mechanism, pipe in from outer tube, extracting out, and regulate after the axioversion angle between two pipes, when control knob resets, will locking inner and outer pipe in, make locator card buckle into the location recessed in, even thereby the external force of being subjected to also can keep the angle that regulates.With finishing, handle control knob, can remove location and locking simultaneously, very convenient.

The specific embodiment

Embodiment one

The universal vacuum cleaner telescopic tube of present embodiment as shown in Figure 1, 2, 3, major part is as follows: core pipe 1, interior pipe 2, outer tube 3, little neck bush 4, sealing ring 5, button push pedal 6, movable lock dog 7, movable slider 8, spring 9, screw 10, nut 11, ball pivot head 12, ball pivot cover 13, big neck bush 14, elbow active connecting base 15, elbow flexibly connect 16, O RunddichtringO 17, button latch Button Block 18, volute spring 19, button snap close 20, button latch buckle closure plate 21, outer tube indentation lock hole 22, crooked lock hole 23.

Core pipe 1 is managed in 2 in scalable being inserted into by the little neck bush 4 of pipe 2 flared section in being fixed on.The flared section of pipe in second retaining mechanism that button push pedal 6, movable lock dog 7, movable slider 8, spring 9, screw 10, nut 11 constitute is installed in, movable lock dog 7 wherein and movable slider 8 are arranged in the carinate groove of fish of core pipe, be subjected to button push pedal 6 controls, play the positioning and locking effect, relevant detailed structure can be referring to CN200510038703.4.

The front end of interior pipe has crooked lock hole 23, and the outer protruding and axial limiting shoulders in location that are shaped on of ball pivot head 12 are fixing in the lock hole 23 of pipe in this ball pivot head is contained in by the location convex clip, and cooperates formation spherical hinge pair with ball pivot cover 13.The flared end insert of outer tube 3 is fixed big neck bush 14, and ball pivot overlaps 13 scalable being inserted in the big neck bush 14, therefore can be in extracting out behind the pipe, by the secondary axial angle of regulating inner and outer pipe of spherical hinge.The outer tube flared end is equipped with first retaining mechanism of being made up of button latch Button Block 18, volute spring 19, button snap close 20, button latch buckle closure plate 21, because of its structure same as the prior art, do not give unnecessary details in addition, button snap close 20 wherein is shaped on elongated end, and elongated end is shaped on the location grab.It is recessed that ball pivot head 12 is shaped on the location in the interior pipe, and the locator card of elongated end is hooked in after the axioversion angle that regulates between two pipes, can be snapped into recessed middle location, location.In addition, be shaped on axial elongated slot on the interior pipe, go deep into the projection of this elongated slot when being shaped on assembling on the outer tube, therefore can avoid inner and outer pipes to relatively rotate, make telescopic adjustment more convenient.

The other end of outer tube 3 is plug-in mounting elbow active connecting base 15 fixedly, and this Connection Block is shaped on and the groove that axially forms angle, and this groove flexibly connects 16 cylindrical with elbow and constitutes hinges with the flange that axially forms corresponding angle.During use, can flexibly connect 16, change and be installed in the angle that elbow flexibly connects a cleaner head on 16, thereby make operation more handy by turning gland.

In a word, convenient, flexible when the universal vacuum cleaner telescopic tube of present embodiment uses, have multiple function and following characteristics:

Compacter when 1, three-joint pipe sleeve structure makes contraction, can save the packed and transported cost, be convenient to deposit;

2, the middle part can be adjusted to required angle by the ball pivot head, during operation more smoothly;

3, rotoflector can be passed through in the termination, thereby replaces the replacing of various in the past angle cleaner head.

In addition to the implementation, the present invention can also have many other embodiments.For example, can combine, form different embodiment with the retaining mechanism of various prior aries.For another example, the interior Guan Yiduan little neck bush of can packing into, and the direct scalable core pipe of plug-in mounting; The outer tube other end is directly made and the groove that axially forms angle, and this groove flexibly connects a cylindrical with elbow and constitutes hinges with the flange that axially forms corresponding angle; Or the like.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
