Description
The utility model relates to a kind of dust catcher parts.
Patent Office of the People's Republic of China discloses the patent No. on January 29th, 97 and has been called the utility model patent of " dust catcher stretch long pipe " for " ZL95244688.x ", name, and it comprises bassoon and tubule, and tubule is enclosed within the bassoon, and the tubule outer wall is provided with cave, some location and guide groove; The termination of described bassoon is connected with a fixed cover, and the inwall of fixed cover is provided with guide pad, in the gathering sill on the guide pad embedding tubule; Also has slide block on the described fixed cover, 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 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; Because guide pad is embedded in the guide groove, so tubule can not rotate in telescopic process.The telescoping tube major defect of said structure is that structure is too complicated, the production cost height.
The purpose of this utility model is: a kind of dust collector expansion pipe is provided, and this tubular construction is simple, dependable performance, easy to use.
The technical solution of the utility model is: a kind of dust collector expansion pipe, comprise outer tube and insert the interior interior pipe of outer tube, edge plastic sheath in the end of described outer tube, the outer wall of pipe is provided with cave, location and locating slot in described, the inwall of plastic sheath be provided with projection embed in the locating slot on the pipe, described outer tube is provided with opening, plastic sheath in the opening is provided with cavity, plastic sheath in the cavity is provided with aperture, and aperture is built-in with steel ball, and steel ball falls on inner pipe the cave, location, also be provided with slide block in the cavity, be fixed with the shifting block that places outer tube outer on the slide block, the front end of slide block is the inclined-plane, and the inclined-plane compresses steel ball all the time under the effect of elastic device.
The further technical scheme of the utility model is: a kind of dust collector expansion pipe, comprise outer tube and insert the interior interior pipe of outer tube, edge plastic sheath in the end of described outer tube, the outer wall of pipe is provided with cave, location and locating slot in described, the inwall of plastic sheath be provided with projection embed in the locating slot on the pipe, described outer tube is provided with opening, plastic sheath in the opening is provided with cavity, plastic sheath in the cavity is provided with aperture, and aperture is built-in with steel ball, and steel ball falls on inner pipe the cave, location, also be provided with slide block in the cavity, be fixed with the shifting block that places outer tube outer on the slide block, the front end of slide block is the inclined-plane, and the inclined-plane compresses steel ball all the time under the effect of elastic device; Described bullet elastic device is a spring steel wire hoop of embracing slide block and plastic sheath.
The utility model has the advantages that:
1. the utility model as long as refer to stir shifting block to the right with hand, is decontroled the slide block of pushing down steel ball in use, just can inner telescoping tube be freely outside with interior pipe, when finger was decontroled shifting block, slide block resetted under the effect of spring steel wire hoop and pushes down steel ball, thus the positioning action of playing.
2. the utility model has replaced dumbbell shaped locating piece of the prior art with steel ball, the structure advantages of simple that more becomes, and replace spring with the spring steel wire hoop, make the product assembling convenient.
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. outer tube; 2. interior pipe; 3. plastic sheath; 4. cave, location; 5. locating slot; 6. opening; 7. cavity; 8. aperture; 9. steel ball; 10. slide block; 11. shifting block; 12. inclined-plane; 13. spring steel wire hoop; 14. projection.
