Abstract
The utility model discloses an extension long connecting tube of a dust collector, comprising a large pipe and a small pipe, wherein, the small pipe is sheathed into the large pipe; the outer wall of the small pipe is provided with a plurality of positioning cavities and guide grooves; the end of the large pipe is connected with a retaining sleeve; the inner wall of the retaining sleeve is provided with guide blocks which are embedded into the guide grooves of the small pipe; the retaining sleeve is also provided with switching blocks; as long as the switching blocks are pushed forwards, dumbbell-shaped positioning blocks spring from the positioning cavities, and thereby, the small pipe can be pulled outwards or pressed inwards; when the switching blocks are loosened, the switching blocks recede backwards under the action of a spring; the positioning blocks are pressed into the positioning cavities by the sloping faces at the back of the switching blocks, in which case the small pipe can be fixed; because the guide blocks are embedded into the guide grooves, the small pipe can not be rotated in the process of extension.
Description
The utility model relates to the tube connector that a kind of dust catcher is used.
Dust catcher tube connector of the prior art, except of extracting from dust catcher body is convenient to the bending with flexible pipe, other tube connector all is to connect with the mode of pegging graft, though this kind connected mode can be said to be more convenient, but its shortcoming also is conspicuous, at first, the suction pipe that this kind mode connects is loosening easily, and it is too big to exert oneself; Secondly, suction pipe leaks gas easily in the junction, and it is many that the suction that is positioned at the suction inlet place has been reduced, and influenced the pick-up performance of dust catcher; Moreover it is cumbersome that many tube connectors are deposited, and gives mixed and disorderly sensation.
The purpose of this utility model is: a kind of dust catcher long pipe that stretches is provided, and it can be made up of the tube connector more than two or two, can arbitrarily elongate or shorten according to operator's needs, and can fix.
The technical solution of the utility model is: a kind of dust catcher long pipe that stretches, it comprises bassoon and tubule, tubule is enclosed within the bassoon, and the same bus of tubule outer wall is provided with the cave, location of several pit shapes separately, and the guide groove of a depression also vertically is set on the outer wall of tubule; The termination of described bassoon is connected with a fixed cover, and the inwall of fixed cover is provided with the guide pad of projection, in the guide groove on the guide pad embedding tubule; Also be provided with a longitudinal opening on the described fixed cover, the rear portion of opening is equipped with the locating piece of a dumbbell shaped, one end of locating piece is fixed on the fixed cover, the other end of locating piece drops in the cave, location of tubule, the front upper place of locating piece is provided with a slide block, locating piece is pushed down on the inclined-plane of the slide block back lower place, is provided with the spring handle slide block between the front end of slide block and opening to pusher, and the section of slide block is the both sides that " worker " font embeds the fixed cover upper shed.
The further technical scheme of the utility model is: a kind of dust catcher long pipe that stretches, it comprises bassoon and tubule, tubule is enclosed within the bassoon, and the same bus of tubule outer wall is provided with the cave, location of several pit shapes separately, and the guide groove of a depression also vertically is set on the outer wall of tubule; The termination of described bassoon is connected with a fixed cover, and the inwall of fixed cover is provided with the guide pad of projection, in the guide groove on the guide pad embedding tubule; Also be provided with a longitudinal opening on the described fixed cover, the rear portion of opening is equipped with the locating piece of a dumbbell shaped, one end of locating piece is fixed on the fixed cover, the other end of locating piece drops in the cave, location of tubule, the front upper place of locating piece is provided with a slide block, locating piece is pushed down on the inclined-plane of the slide block back lower place, is provided with the spring handle slide block between the front end of slide block and opening to pusher, and the section of slide block is the both sides that " worker " font embeds the fixed cover upper shed; Be provided with " U " shape opening around the guide pad on the described fixed cover, make guide pad flexible; The periphery of described fixed cover is coated with a sleeve pipe.
The utility model has the advantages that:
1. at first, the utility model can be compressed in the length of the tube connector more than two or two in the tube connector, makes to deposit and link such as carrying becomes quite convenient.
2. secondly, this syndeton is capable of expansion and contraction, fixed, as long as slide block is pushed away forward, the locating piece of dumbbell shaped is upspring from the cave, location, just tubule can be transferred to or is compressed into, unclamp slide block, slide block is drawn back under spring action, and inclined-plane thereafter presses downward to locating piece in the cave, location, and tubule is fixed.
Moreover, because tubule is provided with guide groove, the fixed cover inwall is provided with guide pad and embeds in the guide groove, so tubule can not rotate in telescopic process.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Wherein: 1. bassoon; 2. tubule; 3. cave, location; 4. guide groove; 5. fixed cover; 6. guide pad; 7. opening; 8. locating piece; 9. slide block; 10. inclined-plane; 11. spring; 12. sleeve pipe.
Embodiment: as Fig. 1, shown in, a kind of dust catcher long pipe that stretches, it comprises bassoon 1 and tubule 2, tubule 2 is enclosed within the bassoon 1, the same bus of tubule 2 outer walls is provided with the cave, location 3 of several pit shapes separately, and the guide groove 4 of a depression also vertically is set on the outer wall of tubule 2; The termination of described bassoon 1 is connected with a fixed cover 5, and the inwall of fixed cover 5 is provided with the guide pad 6 of projection, in the guide groove 4 that guide pad 6 embeds on the tubule 2; Also be provided with a longitudinal opening 7 on the described fixed cover 5, the rear portion of opening 7 is equipped with the locating piece 8 of a dumbbell shaped, one end of locating piece 8 is fixed on the fixed cover 5, the other end of locating piece 8 drops in the cave, location 3 of tubule 2, the front upper place of locating piece 8 is provided with a slide block 9, locating piece 8 is pushed down on the inclined-plane 10 of slide block 9 back lower places, be provided with between the front end of slide block 9 and opening 7 spring 11 slide block 9 to pusher, the section of slide block 9 is the both sides that " worker " font embeds fixed cover 5 upper sheds 7; Be provided with " U " shape opening around the guide pad 6 on the described fixed cover 5, make that guide pad 6 is flexible; The periphery of described fixed cover 5 is coated with a sleeve pipe 12.At first, the utility model can be compressed in the length of the tube connector more than two or two in the tube connector, makes to deposit and link such as carrying becomes quite convenient; Secondly, this syndeton is capable of expansion and contraction, fixed, as long as slide block 9 is pushed away forward, the locating piece 8 of dumbbell shaped is upspring from cave 3, location, just tubule 2 can be transferred to or is compressed into, unclamp slide block 9, slide block 9 is drawn back under spring 11 effects, and inclined-plane 10 thereafter presses downward to locating piece 8 in the cave 3, location, and tubule 2 is fixed; Moreover because tubule 2 is provided with guide groove 4, fixed cover 5 inwalls are provided with guide pad 6 and embed in the guide groove 4, so tubule 2 can not rotate in telescopic process.
