The specific embodiment
Describe the preferred of the handle of vacuum cleaner and the jockey between the flexible pipe with reference to the accompanying drawings in detail
Embodiment.
Fig. 3 to Fig. 5 demonstrates according to rotary type handle syndeton of the present invention.As shown in Figure 3, vacuum cleaner comprises: body of dust collector 1, and its built-in fan motor assembly (not shown) produces suction; Be connected the flexible pipe 2 of the flexibility in above-mentioned body of dust collector 1 the place ahead; At the above-mentioned flexible pipe 2 terminal handles 3 that form; One end is connected the lengthening suction pipe 4 of above-mentioned handle 3; Be connected the suction nozzle 5 of the other end of above-mentioned lengthening suction pipe 4 removably, it moves along ground and sucks extraneous air and dust.
Above-mentioned handle 3 comprises: with the electric wire (not shown) along the inner surface setting of flexible pipe 2 is media, the drive circuit parts (not shown) of the fan motor assembly that is provided with in the body of dust collector 1 and control (control) the parts 3a that is connected in the mode of conducting electricity.The user operates above-mentioned control assembly 3a, just can control the power adjustment of fan motor assembly by handle 3.
In addition, above-mentioned handle 3 is connected the end of lengthening suction pipe 4 in the mode that can rotate freely 360 °, as Fig. 4 and shown in Figure 5, on the periphery of handle 3 ends that are connected with above-mentioned lengthening suction pipe 4, form 2 supporting projections spaced a certain distance 301 along circumferencial direction.Form groove 302 between the above-mentioned supporting projections 301, form several perforation 303 along the mid portion of above-mentioned groove 302.
With the end of the above-mentioned handle 3 terminal lengthening suction pipes 4 that are connected, form guide groove 41 along its circumferencial direction at the position of the above-mentioned perforation 303 of correspondence.The end diameter that forms the lengthening suction pipe 4 of above-mentioned guide groove 41 diminishes gradually, make to insert the end of leading handle 3, and the position that diameter diminishes forms section holder 42.When lengthening suction pipe 4 inserts above-mentioned handle 3, section holder 42 on the above-mentioned lengthening suction pipe 4 contacts with the terminal corner of handle 3, play the effect of the position of relative handle 3 decision lengthening suction pipes 4, after the terminal corner of the section holder 42 contact handles 3 on the above-mentioned lengthening suction pipe 4 was also static, above-mentioned guide groove 41 was corresponding with the perforation 303 of handle 3.
The groove 302 in the outside of above-mentioned handle 3 is provided with the attaching parts 60 that the synthetic resin material is made, and above-mentioned attaching parts 60 make above-mentioned lengthening suction pipe 4 rotatably be combined on the handle 3.These attaching parts 60 comprise the body 61 of annular and protrude several projections 62 of formation along the inner surface of this body 61 that above-mentioned projection 62 has the perforation 303 corresponding shapes and size with above-mentioned handle 3.When above-mentioned attaching parts 60 combined with groove 302 in the outside of above-mentioned handle 3, each projection 62 of attaching parts 60 303 was inserted and is combined on the guide groove 41 by respectively boring a hole of handle 3.
Thereby because the projection 62 of above-mentioned attaching parts 60, above-mentioned lengthening suction pipe 4 is restricted along axial moving, and by the guiding of the projection 62 that is combined in guide groove 41, handle 3 can rotate relatively along circumferencial direction relatively.
The assembling process of aforesaid handle 3 and lengthening suction pipe 4 is as follows.
After the end of lengthening suction pipe 4 inserts handle 3 ends, lengthening suction pipe 4 since its section holder 42 with handle 3 distal edge angular contact and static, this moment, the perforation 303 of handle 3 was corresponding with the guide groove 41 of the suction pipe 4 that extends.
At this moment, after inserted the position of the perforation 303 of the corresponding handle 3 in the position of attaching parts 60 openings, attaching parts 60 elastic dilatations also were inserted into the outer peripheral face of handle 3, are shunk by its elastic force again.Then, the relative outer peripheral face of handle 3, the parts 60 that are rotatably connected gradually make the perforation 303 that each projections 62 of attaching parts 60 is inserted handles 3, in the end insertion and above-mentioned perforation 303 corresponding locational guide grooves 41 of projection 62, and then finish combining between handle 3 and the lengthening suction pipe 4.
Among the aforesaid embodiment, insert the syndeton of handle 3 inside, also can adopt the syndeton in the handle 3 insertion lengthening suction pipes 4 though lengthening suction pipe 4 only has been described.At this moment, opposite among object that perforation 303 and guide groove 41 form and the aforesaid embodiment, attaching parts 60 are also in the outside combination of suction pipe 4 that extends.
