Abstract

The utility model relates to a connecting device for the elbow and hose of a dust collector, which comprises a hose connector embedded in the body of the elbow and a clamping ring below the hose connector, wherein the hose connector comprises an annular body of which the outer wall is in close fit with the inner wall of the body of the elbow, a clamping part which is arranged on the inner wall of the annular body for clamping the hose and a boss which is formed by extending from the lower end of the annular body to the outside and is vertical to the axis of the annular body; part of the lower end face of the annular body is contacted with the upper end face of the clamping ring; and the lower end face of the boss is contacted with the upper end face of the clamping ring. In the connecting device, staggering and falling are effectively prevented due to the large contact area between the connector and the clamping ring. And the connecting device can realize the perfect transition between the linear direction of the connector and the arc direction of the clamping ring, the stresses of all parts are stable, and the sealing effect is desirable.

Description

The jockey 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.Usually, the lower surface of annular body has only part to contact with the upper surface of collar, and the intact transition of the rectilinear direction that this kind structure can not realize joint and the arc direction of collar stressedly between each parts is stablized inadequately, influences sealing effectiveness.

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 described hose coupling, hose coupling comprises outer wall and the mutually close-fitting annular body of the inwall of described bent tubular body and is arranged on the Access Division that is used for the clamping flexible pipe on the inwall of annular body, hose coupling also comprises the boss perpendicular to the annular body axial line that stretches out and form from the lower end of annular body, the part lower surface of annular body contacts with the upper surface of collar, and the lower surface of boss also contacts with the upper surface of collar.

According to further embodiment of the present utility model: described jockey also comprises first chimb that is arranged on the described 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:

The utility model joint also has the boss that stretches out and form from annular body, and this boss plays one by the transition of straight line to circular arc in joint and cooperating of collar.The collar of bottom relies on the active force stepless action on this boss of the joint on top, guarantee that joint can stably be embedded in the bent tubular body, sealing for joint and bent tubular body performs guarantee indirectly, this boss can guarantee to have increased the contact area of joint and collar simultaneously, prevents that effectively dislocation from coming off.

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; 24, boss; 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 20 of the outer wall and the inwall of bent tubular body 1, be arranged on the Access Division 21 that is used for clamping flexible pipe 4 on the inwall of annular body 20, second chimb 22 that is sealed and matched mutually with first chimb 5 that extends upward formation from the upper end of annular body 20, from the upper end of annular body 20 towards the inwall direction of bent tubular body 1 that extend to form with inwall bent tubular body 1 the 3rd chimb 23 of interference fit and the boss 24 that stretches out and form from the lower end of annular body 20 mutually.Boss 24 is perpendicular to the axial line (or sidewall) of annular body 20.Match with the upper surface of collar 3 jointly in the part lower surface of the lower surface of boss 24 and annular body 20.The design of boss 24 is played one by the transition of straight line to circular arc in joint 2 and cooperating of collar 3.The collar 3 of bottom relies on the active force stepless action on this boss 24 of the joint 2 on top, guarantee that joint 3 can stably be embedded in the bent tubular body 1, sealing for joint 2 and bent tubular body 1 performs guarantee indirectly, this boss 24 can guarantee to increase the contact area of joint 2 with collar 3 simultaneously, prevents that effectively dislocation from coming off.

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.
