Abstract
The invention relates to a multifunctional retractile device, which comprises an outer cylinder and an inner cylinder, wherein the near ends of the outer cylinder and the inner cylinder are provided with openings, and the far ends are sealed; a sealing ring is fixed on the inner cylinder; and the far ends of the outer cylinder and the inner cylinder are fixedly connected with a sleeve; the sleeveis fixedly provided with an inner cylinder brake needle (also can be a block or a ball); the corresponding outer wall of the inner cylinder is provided with a limiting groove; the other end of the inner cylinder brake needle is positioned in the limiting groove; and the far end of the innermost inner cylinder is fixedly connected with a retractile rope. Because of the adoption of the technical scheme, the multifunctional retractile device has the following advantages: freely and thoroughly retracting by adopting a plurality of inner cylinders so as to be suitable for use in various environments and various instruments.
Description
Technical field
The present invention relates to a kind of component, especially a kind of multifunctional retractile device.
Background technique
At present, the flexible rod on the market can only be retracted to its degree of 1/2nd mostly, and to shrink be not easily, on some large-scale apparatuses, replaces the debit with folding especially, take up an area of big, in carrying or very inconvenient when mobile.
Summary of the invention
At above-mentioned existing problems, the invention provides a kind of multifunctional retractile device, adopt new stretch mode, simple to operate easily labor intensity is little, is suitable for various places, can be widely used on the various apparatuses, on the device of the flexible folding and unfolding of especially large-scale need.
In order to reach above purpose, the present invention takes following technological scheme, and a kind of multifunctional retractile device comprises urceolus and inner core, urceolus and inner core have opening at near-end, far-end seals, and seal ring is fixed on the inner core, is connected with a sleeve at urceolus and inner core far-end, be fixed with inner core braking pin (also can be piece and ball) on the sleeve, have restraining groove on the inner tank theca of correspondence, the other end of inner core braking pin is positioned at restraining groove, and the inner core far-end in is connected with a retraction cord.
Because the present invention has taked above technological scheme, has the following advantages: adopt the more piece inner core, can freely stretch, and contraction ratio is more thorough, thus the use of the suitable various apparatuses of various environment.
Description of drawings
Fig. 1 executes routine structural representation for an example of the present invention
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Embodiment one
As shown in Figure 1, a kind of multifunctional retractile device of the present invention, comprise urceolus 1 and inner core 2, urceolus 1 and inner core 2 have opening at near-end, far-end seals, seal ring 3 is fixed on the inner core 2, seal, be connected with a sleeve 4 at urceolus 1 and inner core 2 far-ends, be fixed with inner core braking pin 5 (also can be piece and ball) on the sleeve 4, have restraining groove on the inner tank theca of correspondence, the other end of inner core braking pin is positioned at restraining groove, inner core 2 is carried out spacing when stretching and contract, the inner core remote branch of a clan pole point in is connected with a retraction cord 7.During folding and unfolding, by to rope or the inner core do work and just can achieve the goal.
When using as spray boom, urceolus 1 and inner core 2 are being provided with spray orifice 6 near sleeve 4 ends.
Work is advanced, when air-flow or liquid flow in the spray boom, air-flow or liquid stream at first is that (inner core internal diameter is greater than inferior inner core to inner core effect, so air-flow or liquid stream to the active force of inner core greater than inferior inner core, so inner core is at first overhanging), promote inner core 2 to overhanging, when going to these inner core 2 ends, be subjected to the effect of inner core braking pin 5 to stop overhanging action, the spray orifice of inferior inner core is opened, and meanwhile air-flow or liquid stream begin inferior inner core effect, analogize in proper order, during contraction, pulling retraction cord 7, equally at first (retraction cord is fixed on the inner core to inner core effect, motive force directly acts on inner core), when inner core was retracted to the end, the inner core of 5 pairs on inner core braking pin carried out spacing, and so inner core contracts in no longer, so under the effect of motive force, motive force by inner core braking pin 5 force transmission to the sleeve of inferior inner core, and drive in time inner core and contract, shrink fully to the end by that analogy or specify and shrink.
When considering the aerial spraying continuous running, sometimes can be sprayed object in the air,,, open or close automatically and close shower nozzle according to having of sensing or when not having aerial crop so an inductor 8 is installed on the top of spray boom.
In addition to the implementation, the present invention can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
Claims (4)
1, a kind of multifunctional retractile device, comprise urceolus and inner core, urceolus and inner core have opening at near-end, far-end seals, and seal ring is fixed on the inner core, is connected with a sleeve at urceolus and inner core far-end, be fixed with inner core braking pin (also can be piece and ball) on the sleeve, have restraining groove on the inner tank theca of correspondence, the other end of inner core braking pin is positioned at restraining groove, and the inner core far-end in is connected with a retraction cord.
