Description
Technical field
The present invention relates to a kind of vacuum cleaner telescopic tube structure, particularly the latch-up structure technical field of the flexible length of control pipe.
Background technology
Existing vacuum cleaner telescoping tube is multifarious, have plastics, mutually inserted ...Although in use each has something to recommend him, always unsatisfactory part is arranged.Along with the raising of living standards of the people, household electrical appliance are accompanied by good looking appearance, luxurious, inherent easy-to-use function sturdy and durable, simple to operate, come into huge numbers of families.Present telescoping tube is made as plastics, because its material properties is limit, just progressively be tending towards superseded, and the steel pipe telescoping tube is many based on portable switch, is 98223202.0 Chinese patent " telescoping tube on the dust catcher " as application number, application number is Chinese patent " telescopic pipe on the dust catcher " of 98122063.0 or the like, when the user operates, speckle with unclean thing sometimes on hand, skid easily when regulating pipe length, impact resistance is not good enough, and two pipes such as tangentially rock easily at shortcoming.
Summary of the invention
Technical problem to be solved by this invention provides degree of blocking height between a kind of spry and light, telescoping tube easy to use, be difficult for the telescopic steel pipe of suction cleaner that tangentially rocks.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this telescopic steel pipe of suction cleaner, include the inside and outside pipe that is nested together, be provided with flexible locking mechanism between the inside and outside pipe, it is characterized in that latch-up structure is the elongated slot that is pressed with equidistant spill crater on the interior pipe coaxial direction periphery, outer outer tube one end of pipe is expanded into cannula-like in being enclosed within, interior annular space with interior pipe formation certain distance, the plastics of packing into joint cover, joint cover internal diameter with interior external diameter of pipe for movingly, and be shaped on band shell hole and a pellet shot from a slingshot with the corresponding rectangle convex tendon that limits tangential rotation of interior pipe range groove, on the wall of plastics joint cover external diameter, court is an end of expander not, the pipe groove has bar rectangular for the groove that slides before and after the slide block on one side in corresponding its sleeve pipe, have the hole on the jacket wall of joint cover outer wall groove back, corresponding outer tube enlarged also has the hole, and be fixed with switch base, have axial notch in the middle of the switch base, shape becomes a chute part with the corresponding also linking of joint cover front end, the shaft hole that button one end has on rotating shaft and the pedestal is connected, other end lower abdomen has leg-of-mutton skewback, triangled tip inserts in the middle slot of slide block, propping up between the fulcrum on slide block and the switch base simultaneously has spring, and last cover of upholstery is held on the switch base.
Compared with prior art, the invention has the advantages that: this telescoping tube uses, as long as grasping the switch position one pinches gently, the pipe length of just can stretching like a cork, avoid speckling with on hand the sorrow that different liquid skids easily on switch, easy to use, light and handy, independent mortise and tenon type combination assembling is adopted in switch combination, eliminate the loosening easily disadvantage of switch in the product use, anti-impact force is strengthened, the chute that interior pipe is wide and shallow, bottom land is interspersed equally distributed crater, both increased the attractive in appearance of integral body, the gap of having reduced tangential rotation between steel pipe again is so be difficult for loosening the rotation.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in the figure, this telescopic steel pipe of suction cleaner is made up of two inside and outside pipes that are nested together, be pressed with the elongated slot 1 in equidistant spill crater 8 on the interior pipe coaxial direction periphery, the arch form that bottom land is slightly parallel with tube wall or flat, outer outer tube 2 one ends of pipe are expanded into cannula-like in being enclosed within, interior annular space with interior pipe formation certain distance, the plastics of packing into joint cover 3, the internal diameter of joint cover is realized movingly with the external diameter of interior pipe, and have band shell hole 15 and a pellet shot from a slingshot 4 with the corresponding rectangle convex tendon 13 of interior pipe range groove, envoy cover pack into sleeve pipe that outer tube enlarged interior after, can freely endwisely slip on inner pipe, and can not do tangential the rotation along interior pipe, on the wall of plastics joint cover external diameter, court is an end of expander not, corresponding its internal surface of sleeve pipe tongue on one side, the rectangular groove 14 of bar is arranged, in order to the slide block 6 of packing into, slide block can be slided in groove, have a rectangular hole 20 on the back jacket wall of joint cover outer wall groove, this hole is corresponding with 17 of the slots that has four outstanding blockages 16 that outer tube expansion section branch leaves, switch base 5 bottoms are shaped on convex tendon 11, the axial two side of switch base has and pairing groove 18 of the outer tube slot of four outstanding blockages and side channel 19, switch base embeds outer tube and saves in the cover, move to expander end not, four blockages of outer tube part promptly embed in the seam axial on the pedestal, little oblong aperture remaining on the tube wall is filled in a month arc square 7, with whole switch base, the joint cover, outer tube tightens together, have axial groove 21 in the middle of the switch base, shape and the corresponding linking of joint cover front end, become a chute part, the shaft hole 23 that one end of button 9 has on rotating shaft 22 and the pedestal is connected, other end lower abdomen has leg-of-mutton skewback 24, can be that fan-shaped rotation is done at the center along rotating shaft, triangled tip inserts in the middle oblong aperture of slide block, promoting slide block moves backward, prop up between the fulcrum on slide block and the switch base spring 25 is arranged, and the switch base both sides have with stinging of interlocking of cover of upholstery biside plate and collude 12, and cover of upholstery 10 links closely on the switch base then.
Its operation principle process is as follows: press the button with hand, the triangle skewback is around the past lower swing of axle, in the slot of wedging slide block, because the effect of inclined-plane and lever, slide block is moved backward along groove, and the pellet shot from a slingshot in the shell hole is owing to the constraint of having removed slide block, when steel pipe moves at this moment, can automatically jump out the crater, outer and inner tube moves freely each other.And when finger left button, spring overcame resistance, the slide block top forwards, because front end circular arc inclined-plane forces pellet shot from a slingshot to be dropped in the shell hole, slide block continues forward, move on to the pellet shot from a slingshot top until the slider bottom plane, slide block is in outer tube and the formed square hole of joint cover, and space of slider is very little, when external force forces outer and inner tube to move axially, acting on the steel pipe top forces pellet shot from a slingshot to be jumped outward, but because of stopping of slide block, pellet shot from a slingshot can't relatively move, so just pinned tightly between the steel pipe.
