Description

Multi-joint connecting device of dust collector

Technical Field

The utility model relates to a dust catcher field specifically relates to a multi-joint connecting device of dust catcher.

Background

Along with the popularization of dust collectors in China, people pay more and more attention to the convenience in use, the functions of the dust collectors are complete, and along with the diversification of the functions and accessories, a user needs to frequently replace the accessories and adapt to certain electric tools to be used with the dust collectors in the using process. At present, dust collector manufacturers can only use a plurality of parts with different calibers or matched with electric tools.

The use of multiple parts of different calibers or to mate with the power tool creates the annoyance that it is difficult for the user to tell which part mates with the accessory. And the condition that air leakage occurs frequently when the matching is not good or parts are removed frequently when a user uses the electric appliance for a period of time occurs.

SUMMERY OF THE UTILITY MODEL

To the defect that exists among the above-mentioned prior art, the utility model aims at providing a multi-joint connecting device of dust catcher makes the dust catcher of different bores and the electric tool of difference or the annex between be connected and can only realize through a connection structure, reduces dust catcher producer cost, and convenience of customers uses simultaneously.

In order to achieve the above purpose, the utility model provides a technical scheme as follows:

the utility model provides a multi-joint connecting device of dust catcher, connecting device is the tubular structure of diameter gradual change, is provided with a plurality of interior steps and outer step on tubular structure's the inside wall and the lateral wall respectively, and the outer step of different diameters department is used for connecting different dust catcher annex or electric tool and connects, and the interior step of different diameters department is used for connecting the hose coupling of different bores of dust catcher.

The side wall of the tubular structure is provided with a taper at the joint matching part with the joint so as to fix the connection state.

Is made of soft material with moderate hardness.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model provides a universal connection structure of dust collector, this structure can be applicable to the dust collector of different bores, the electric tool of different bores or the connection that the annex connects, only can realize through a connection structure. The connecting structure is made of soft materials, and the hardness is moderate, so that the parts are matched with each other to have a sealing effect.

Drawings

Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:

fig. 1 is a schematic structural diagram of a connection device provided by the present invention.

Detailed Description

The present invention will be described in detail with reference to the following embodiments. The following examples will assist those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.

As shown in fig. 1, the utility model provides a multi-joint connecting device of a dust collector, which is tubular with a diameter varying from small to large, and is provided with a plurality of inner steps 1 and outer steps 2 on the inner side wall and the outer side wall of the tubular structure respectively. The outer steps 2 on the outer side wall are symmetrically arranged, and the inner steps 1 on the inner side wall are symmetrically arranged.

Because the inner steps 1 or the outer steps 2 at different positions have different diameters, the outer steps 2 are connected with the fittings of the accessories or the electric tools with different sizes in various sizes, and the inner steps 1 are connected with the hose fittings of the dust collector with different calibers in various sizes. In order to fix the connection state between the joints, tapers are provided at the mutual fitting portions of the joints.

The utility model discloses a connecting device adopts the software material preparation, and material hardness is moderate for there is sealed effect when the part is mutually supported.

The foregoing description of the specific embodiments of the invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes or modifications may be made by those skilled in the art within the scope of the appended claims without departing from the spirit of the invention. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.

Claims
