Abstract

The utility model relates to a dust collector elbow, which comprises an elbow body, a hose connector, a retainer ring and a button, wherein the hose connector is embedded into one end of the elbow body, the retainer ring is positioned in the elbow body, the upper end face of the retainer ring is matched with the lower end face of the hose connector in a sealed manner, and the button is arranged between the elbow body and the retainer ring. The elbow body is provided with a button hole; the outer wall of the retainer ring is recessed inwardly to form a groove; the button includes a pressing portion and an elastic portion; the pressing portion extends out of the button hole; the elastic portion is positioned on the inside of the pressing portion and contained in the groove; three abreast ribs are formed on an inside plane of the elastic portion; long edges of the three ribs extend on the inside plane of the elastic portion; and the height of each rib is smaller than the depth of the groove. The ribs formed on the inside plane of the elastic portion of the button can evenly scatter acting force exerted on the elastic portion when the button is pressed, so that the shortcomings of whitening and incapability of rebounding due to permanent deformation after force bearing of an existing button in use can be avoided effectively.

Description

A kind of dust catcher bend pipe

Technical field

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

Background technology

In the prior art, dust catcher bend pipe (handle) generally comprises bent tubular body, be embedded hose coupling in bent tubular body one end, be arranged on the collar that is positioned at the hose coupling outside in the bent tubular body, and be arranged on button between bent tubular body and the collar, offer button hole on the bent tubular body, the outer wall of collar caves inward and is formed with groove, and described button comprises from the press section that button hole stretches out and to be positioned at the press section inboard and be contained in the elastic portion of groove.When pushing button, because the elastic portion discontinuity, be prone to after making button in use stressed and turn white and deficiency that permanent deformation can't rebound

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, it comprises bent tubular body, be embedded the hose coupling in bent tubular body one end, be positioned at the collar that bent tubular body and 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, offer button hole on the bent tubular body, the outer wall of collar caves inward and is formed with groove, button comprises from the press section that button hole stretches out and to be positioned at the press section inboard and be contained in the elastic portion of groove, form at least two convex tendons on the inner side plane of described elastic portion, extend on the inner side plane of elastic portion on the long limit of this convex tendon, and the height of convex tendon is less than the degree of depth of groove.

Preferably, convex tendon has 3, and these 3 convex tendons are arranged side by side on the inner side plane of elastic portion.

Preferably, button has 2, and 2 buttons are symmetrical arranged about the center line of collar.

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

Active force when the utility model has disperseed button press by at least two convex tendons that form on the elastic portion inner side plane of button, and active force is uniformly dispersed, can effectively avoid existing button in use because of the deficiency that occurs after stressed turning white and permanent deformation can't rebound.

The specific embodiment

Shown in Fig. 1 to 6, dust catcher bend pipe according to present embodiment comprises bent tubular body 1, be embedded the hose coupling 2 in bent tubular body 1 one ends, be positioned at the collar 3 that bent tubular body 1 and 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, offer button hole 10 on the bent tubular body 1, the outer wall of collar 3 caves inward and is formed with groove 30, button 4 comprises from the press section 40 that button hole 10 stretches out and to be positioned at press section 40 inboard and be contained in the elastic portion 41 of groove 30, be formed with three convex tendons that are arranged side by side 42 on the inner side plane of elastic portion 41, extend on the inner side plane of elastic portion 41 on the long limit of convex tendon 42, and the height of convex tendon 42 is less than the degree of depth of groove 30.

In the present embodiment, button 4 has 2, and these 2 buttons 4 are symmetrical arranged about the center line of collar 3.

The bend pipe of present embodiment, owing on elastic portion 41 inner side plane of button 4, be formed with three convex tendons 42, guaranteed when button 4 is subjected to pushing, therefore its elastic portion 41 suffered active forces can evenly be disperseed by convex tendon 42, have effectively avoided existing button in use because of the deficiency that occurs after stressed turning white and permanent deformation can't rebound.

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
