Abstract

The utility model relates to a bent pipe for a dust collector, which comprises a bent pipe body, a hose joint, a clamping ring and a button, wherein the hose joint is embedded in the bent pipe body; the upper end face of the clamping ring is in sealed fit with the lower end face of the hose joint; the button is arranged between the bent pipe body and the clamping ring; the clamping ring comprises an arc section positioned in the bent pipe body, a straight line section extending out of the bent pipe body and an opening section which extends outwards from the straight line section to form the outer end part of the clamping ring; the opening section takes a shape of a horn of which the inner diameter is gradually increased from inside to outside; and the surface of the opening section is of an arc shape. The arc surface formed by a horn opening of the clamping ring can support for a hose, so that the surface of the hose is stressed evenly and the hose is prevented from being broken due to excessive local stress.

Description

The dust catcher bend pipe

Technical field

The utility model relates to a kind of dust catcher bend pipe.

Background technology

In the prior art, the dust catcher bend pipe generally comprises bent tubular body, be embedded hose coupling in bent tubular body, in bent tubular body and the collar that is sealed and matched mutually of upper surface and the lower surface of hose coupling and be arranged on bent tubular body and collar between button, wherein collar is made of segmental arc that is positioned at bent tubular body and the straightway that stretches out described bent tubular body.Take the collar of this structure, the opening of its straightway can not well cooperate with flexible pipe, and situation about rupturing because of local pressure is excessive appears in hose surface discontinuity equalization easily.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of improved dust catcher bend pipe is provided.

For solving above technical problem, the utility model is taked following technical scheme:

A kind of dust catcher bend pipe, the collar that it comprises bent tubular body, be embedded hose coupling in bent tubular body, upper surface and the lower surface of hose coupling are sealed and matched mutually, be arranged on the button between bent tubular body and the collar, collar comprises the segmental arc that is positioned at bent tubular body and stretches out the straightway of bent tubular body and stretch out from described straightway and constitutes the open section of described collar outer end, this open section is the diameter from-inner-to-outer and becomes big tubaeform gradually, and the surface of open section is an arc.

Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:

The formed arcwall face of the horn mouth of collar of the present utility model can provide support flexible pipe, makes the hose surface stress equalization, prevents that flexible pipe from rupturing because of local pressure is excessive.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in more detail:

Fig. 1 is the main cross-sectional schematic according to dust catcher bend pipe of the present utility model;

Fig. 2 is the schematic perspective view according to collar of the present utility model and button;

Fig. 3 looks schematic diagram for the master of Fig. 2;

Fig. 4 is the assembling schematic diagram of bend pipe of the present utility model and flexible pipe;

Wherein: 1, bent tubular body; 2, hose coupling; 3, collar; 30, segmental arc; 31, straightway; 32, open section; 4, button; 5, flexible pipe.

The specific embodiment

As shown in Figures 1 to 3, the collar 3 that the dust catcher bend pipe according to present embodiment comprises bent tubular body 1, is embedded hose coupling 2 in bent tubular body 1, upper surface and the lower surface of hose coupling 2 are sealed and matched mutually, be arranged on the button 4 between bent tubular body 1 and the collar 3.Collar 3 constitutes by the segmental arc 30 that is positioned at bent tubular body 1, the straightway 31 that stretches out bent tubular body 1 and from described straightway 31 open section 32 that constitutes collar 3 outer ends that stretches out, this open section 32 is the diameter from-inner-to-outer and becomes big tubaeform gradually, and the surface of open section 32 is an arc.

Referring to Fig. 4, the formed arcwall face of the horn mouth of the collar of present embodiment can provide support flexible pipe 5, makes flexible pipe 5 surperficial stress equalizations, prevents that flexible pipe 5 from rupturing because of local pressure is excessive.

More than the utility model has been done detailed description; its purpose is to allow the personage that is familiar with this art can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to spiritual essence of the present utility model change or modify, and all should be encompassed in the protection domain of the present utility model.
