Abstract
The utility model discloses a blowpipe connecting structure which comprises a first blowpipe, a second blowpipe, a special screw, a support sleeve and a nut. The blowpipe connecting structure is characterized in that a boss is arranged at one end of the first blowpipe, the nut is cast on the first blowpipe, a rotation guide path, a pit, a protrusion, a protruding column are arranged at one end of the second blowpipe, the pit is arranged at the tail end of the rotation guide path, and the pit and the rotation guide path are separated through the protrusion. The support sleeve is assembled in the protruding column, the special screw is assembled in the support sleeve, the boss of the first blowpipe right faces to the rotation guide path of the second blowpipe and then is pushed and screwed in the pit, the special screw is screwed in the nut right facing the special screw and is tightly screwed, and rapid and firm connection between the first blowpipe and the second blowpipe are completed. The connection mode can thoroughly solve the problem that blowpipes are easy to drop due to deformation, removes hose clamps for banding, reduces cost, simplifies connection and beautifies appearance.
Description
Technical field
The utility model relates to the portable dam technical field, particularly blows the air feeding tube linkage structure through the wind-force operation such as Bothridium Machine, sprayer-duster.
Background technique
At present; The portable air feeding tube that blows Bothridium Machine and sprayer-duster such as hand-held, backpack has 2～4 joints usually, and the material multiselect has been used high density polyethylene (HDPE), adopts blow molding process to be made; Thereby make efficiency is high, tube wall is thin, in light weight, cost is low, satisfies very much the requirement of portable operation; Again owing to the connection of two joint air feeding tubes is that the rotation of adopting the boss of an air feeding tube to align another air feeding tube is led to screw in to accomplish and is linked and packed, but because the softer easy deformation of plastic tube quality of thin-walled, the reliability connection between each saves the effect of wind-force has under just become problem; Through regular meeting the phenomenon that air feeding tube comes off takes place in use, at present, addressing this problem is to be employed in the method that each internode ties up with the larynx hoop to realize; But tie up not only cost height owing to adopt the larynx hoop; Outside complicated operation, outward appearance were not attractive in appearance, operator's thing also often appearred scratching; Therefore, be badly in need of a kind of air feeding tube Placement attractive in appearance, reliable, easy and simple to handle.
Summary of the invention
The purpose of the utility model provides a kind of Placement of air feeding tube of blow molding process making; This Placement can guarantee the connection rapidity between the air feeding tube; Guarantee the reliable, stable of its connection, simplicity generosity attractive in appearance is again given competitiveness of product and vitality.
The technological scheme that the utility model is taked is: a kind of air feeding tube linkage structure comprises air feeding tube one, air feeding tube two, special screw, supporting sleeve, nut; It is characterized in that: an end of said air feeding tube one is provided with boss, and said nut casting is combined on the air feeding tube one; One end of said air feeding tube two is provided with that rotation is led, pit, convexity, projection, and said pit is arranged on the end that rotation is led, and separates through protruding leading with rotation; Said supporting sleeve is assemblied in the projection, and special screw is assemblied in the supporting sleeve; Advance after the rotation that the boss of said air feeding tube one aligns said air feeding tube two is led to be screwed in the pit, tighten in the said nut that the special screw precession is aligned with it, accomplish the quick of air feeding tube one and air feeding tube two and firmly be connected.
The bar portion of said special screw is made up of smooth shank portions and thread head, and smooth shank portions is thinner than thread head.
Said projection is provided with round tube hole, and round tube hole is thinner than thread head, and is thicker than smooth shank portions, and special screw can not come off along the free play of its axis in supporting sleeve.
The beneficial effect of the utility model is; Compare with traditional air feeding tube Placement, this Placement realizes the firm connection between air feeding tube through being connected of special screw and nut, and special screw and nut all are placed on the air feeding tube; Easy and simple to handle; Simultaneously less, subtle because of part, do not destroy the succinct, attractive in appearance of air feeding tube profile; Supporting sleeve is assemblied on the air feeding tube special screw is played fixing, supporting effect, improves its reliability.

Embodiment
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5; The utility model air feeding tube linkage structure comprises air feeding tube 1 (boss 12), nut 11, air feeding tube 22 (spiral leads 1, protruding 3, pit 4, projection 7, round tube hole 6), special screw 5 (thread head 9, smooth shank portions 10), supporting sleeve 8.
Supporting sleeve 8 interference are installed in the projection 7 of air feeding tube 22, and the thread head 9 of special screw 5 is inserted in the hole of supporting sleeve 8.
The concrete working procedure of the utility model: the spiral that the boss 12 of air feeding tube 1 inserts air feeding tubes 22 is led 1 back and is advanced and be screwed in protruding 3 o'clock precession pits 4 of exerting oneself, and accomplishes the locking of first road; At this moment the special screw 5 that is installed on the air feeding tube 22 just in time aligns with the nut 11 that is inlaid on the air feeding tube 1; With screw-driver special screw 5 is screwed in the nut 11; Accomplish for the second time firm locking; Air feeding tube can not come off under the situation of not tool using dismounting like this, guarantees connection firm between the air feeding tube.
A plurality of air feeding tubes can be provided with as above identical linkage structure when connecting and get final product.
Portable blow Bothridium Machine and sprayer-duster in operation process because the softer easy deformation of plastic tube quality of thin-walled has just become problem in the reliability connection between each joint effect of wind-force under, the phenomenon that air feeding tube comes off in use takes place through regular meeting; At present; Addressing this problem is to be employed in the method that each internode ties up with the larynx hoop to realize, but owing to adopt the larynx hoop to tie up that not only cost is high, complicated operation; Outside outward appearance was not attractive in appearance, operator's thing also often appearred scratching; Adopting should invention, and promptly the Placement with screw, nut has not only solved the easy obscission of air feeding tube, has removed the larynx hoop, and has reduced cost, connect easy, overall appearance, succinct, generous.
