Abstract

The utility model relates to a connecting device for a bent tube and a flexible tube of a dust collector, which comprises a flexible tube joint embedded in a bent tube body, and a clamp ring positioned under the flexible tube joint, wherein the flexible tube joint consists of an annular body with the inner wall tightly matched with the inner wall of the bent tube body, and a clamping part arranged on the inner wall of the annular body and used for clamping the flexible tube, the connecting device further comprises a first convex edge that is arranged on the inner wall of the bent tube body, the flexible tube joint further comprises a second convex edge and a third convex edge, wherein the second convex edge is formed by upwards extending from the upper end of the annular body and is matched with the first convex edge tightly, and the third convex edge is formed by upwards extending from the upper end of the annular body towards the direction of the inner wall of the bent tube body and is in clearance fit with the inner wall of the bent tube body. In the connecting device, the good sealing effect can be achieved through utilizing the tight match between the first convex edge and the second convex edge, and the clearance fit between the third convex edge and the inner wall of the bent tube body.

Description

The jockey of a kind of dust catcher bend pipe and flexible pipe

Technical field

The utility model relates to a kind of jockey that is used to connect dust catcher bend pipe and flexible pipe.

Background technology

In the prior art, dust catcher transfers the windbend pipe (handle) and the jockey of flexible pipe to comprise the hose coupling that is embedded in bent tubular body one end and be arranged on the collar that is positioned at the described hose coupling outside in the described bent tubular body, wherein, hose coupling is by the close-fitting annular body of the inwall of an outer wall and described bent tubular body be arranged on the Access Division that is used for the clamping flexible pipe on the inwall of annular body and constitute.Take the jockey of this structure, sealing is not fine.

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 dust catcher bend pipe of better tightness and the jockey of flexible pipe are provided.

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

The jockey of a kind of dust catcher bend pipe and flexible pipe, it comprises the hose coupling that is embedded in bent tubular body and is positioned at collar below the hose coupling, hose coupling comprises outer wall and the mutually close-fitting annular body of the inwall of bent tubular body and is arranged on the Access Division that is used for the clamping flexible pipe on the inwall of annular body, described jockey also comprises first chimb that is arranged on the bent tubular body inwall, hose coupling also comprise second chimb that is sealed and matched mutually with first chimb that extends upward formation from the upper end of annular body and from the upper end of annular body towards the 3rd chimb of the inwall direction inwall phase interference fit that extend to form and bent tubular body of bent tubular body.

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

First chimb of the present utility model is sealed and matched mutually with second chimb, particularly when having wind to pass through in the pipe, because of interior pressure greater than external pressure, make second chimb be subjected to inside active force, and be close on first chimb, guaranteed good sealing effectiveness; In addition, the utility model also is provided with and the inwall of bent tubular body second chimb of interference fit mutually, has further improved sealing effectiveness.

Description of drawings

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

Fig. 1 cuts open schematic diagram for the master according to the jockey of dust catcher bend pipe of the present utility model and flexible pipe;

Fig. 2 is a schematic perspective view of getting the assembly of bend pipe of the present utility model and flexible pipe;

Fig. 3 cuts open schematic diagram for the master of Fig. 2;

Fig. 4 for do not have wind by the time Fig. 2 the master cut open schematic diagram (flexible pipe does not show);

Fig. 5 be have wind by the time Fig. 2 the master cut open schematic diagram (flexible pipe does not show);

Wherein: 1, bent tubular body; 2, hose coupling; 20, annular body; 21, Access Division; 22, second chimb; 23, the 3rd chimb; 3, collar; 4, flexible pipe; 5, first chimb.

The specific embodiment

Shown in Fig. 1 to 5, comprise the hose coupling 2 that is embedded in bent tubular body 1, be positioned at the collar 3 below the hose coupling 2 and be arranged on first chimb 5 on bent tubular body 1 inwall according to the jockey of the dust catcher bend pipe of present embodiment and flexible pipe.Described hose coupling 2 comprises the mutually close-fitting annular body of the outer wall and the inwall of bent tubular body 1 20 and is arranged on the inwall of annular body 20 second chimb 22 that is sealed and matched mutually with first chimb 5 that is used for the Access Division 21 of clamping flexible pipe 4, extends upward formation from the upper end of annular body 20 and the 3rd chimb 23 that extend to form towards the inwall direction of bent tubular body 1 from the upper end of annular body 20 and inwall phase interference fit bent tubular body 1.Referring to Fig. 4 and Fig. 5, when ventilating, because of interior pressure greater than external pressure, second chimb 22 is subjected to inside active force and is close on first chimb 5, has guaranteed good sealing effectiveness.In conjunction with the interference fit of the inwall of the 3rd chimb and bent tubular body 1, make the sealing that connects be further enhanced again.

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.
