Abstract
A leakage-proof follow-up structure is flexible and comprises an outer bushing, an inner bushing and a rubber ring. The outer bushing is provided with one aperture at least. A rubber ring slot and a guide slot are arranged in the aperture. One end of the inner bushing is transfixed in the aperture of the outer bushing. The rubber ring is arranged in the rubber ring slot. The utility model is characterized in that a movable baffle ring is arranged in the guide slot of the outer bushing; the baffle ring can slide in the guide slot as the inner bushing rotates, thus the rubber ring is stationary. The bushing is tended to flex and swing laterally, causing distortion or displacement. For the sake of advantages, the distortion and displacement of the rubber ring are avoided, and the swing angle of the inner bushing is increased.
Description
Technical field
The utility model relates to a kind of servo-actuated leak stoppage structure of flexible tube, be meant especially and utilize a movable baffle ring of being located in the outer sleeve, cooperate the leak-stopping cushion rubber, make pipeline can allow the off normal action of flexible and rotation, effectively reduce the situation generation that flexible tube leaks, and can increase the bigger rotation swing angle of inner sleeve.
Background technique
Various on the market at present fluid delivery systems damage because of factors such as earthquakes for avoiding delivery pipe, thus can use flexible tube to come absorbing vibration, and make the installing route of delivery pipe that bigger elasticity be arranged.And single sometimes delivery pipe can't directly arrive the desired position, and then need use a special joint to connect two delivery pipes this moment, reaches the purpose of prolongation; This special joint also need have to prevent the function of leaking except the function that connects.
As shown in Figure 5, the flexible tube of commonly using comprises: an outer sleeve 90 is provided with baffle ring 91 in its both ends open; And two inner sleeves 92, be arranged in outer sleeve 90 openings at two ends; And two aprons slots 93, be located at outer sleeve 90 two ends; And two leak-stopping cushion rubbers 94, be located in the aprons slot 93.Wherein inner sleeve 92 is to be connected in order to the pipeline adjacent with two ends.
Shown in Fig. 6～7, adjacent pipeline is subjected to external force to do the time spent when two ends, and inner sleeve 92 can produce action flexible or rotation; At this moment, the baffle ring 91 on the outer sleeve 90 must make flexible tube can bring into play the function of expection baffle ring 91 shorten lengths for not making the action of limit inner sleeve 92.
As shown in Figure 7, because of the shorten length of baffle ring 91, when inner sleeve 92 is mobile in the outer sleeves 90, can drive 94 distortion and the displacements of leak-stopping cushion rubber, the function of reduction leak-stopping cushion rubber 94 is leaked flexible tube.
In sum, the flexible tube of commonly using is because of the shorten length of the baffle ring on the outer sleeve 90 92, and reduced the sealing function of leak-stopping cushion rubber 94, causes escape of liquid; Supervise in this, this creator is at the leak-stopping cushion rubber of commonly using flexible tube, thinks hard funiculus, and active research is added continuous experiment improvement, develops finally the utility model.
Summary of the invention
The purpose of this utility model is providing a kind of servo-actuated leak stoppage structure that can not make the flexible tube of cushion rubber generation displacement and distortion because of the flexible and rotation of inner sleeve.It is textural to be to be provided with an outer sleeve, and tool one opening is provided with aprons slot and guide groove in opening at least; And inner sleeve, be set in the opening of outer sleeve; And cushion rubber, be located in the aprons slot; Wherein be provided with a movable baffle ring in the guide groove of outer sleeve; When the inner sleeve rotary oscillation, movable baffle ring can slide in guide groove in the action with inner sleeve, the action of restriction leak-stopping cushion rubber can effectively avoid cushion rubber because of the flexible of inner sleeve and rotation beat produce the phenomenon of distortion and displacement, makes the complete driving fit in internal and external casing suit place and has leakage-proof effect.
Another purpose of the present utility model is at the servo-actuated leak stoppage structure of the flexible tube that the bigger rotation swing angle of a kind of inner sleeve tolerable is provided.It is textural to be to establish a guide groove on outer sleeve, makes and establishes a movable baffle ring in this guide groove; This movable baffle ring can make inner sleeve that bigger rotation swing angle be arranged according to the action of inner sleeve in middle slip.
The utility model is adorned movable baffle ring and is circular, can avoid injuring the inner sleeve surface.
In sum, the movable baffle ring of the utility model utilization has limited the mobile space of cushion rubber, makes cushion rubber can cooperate the rotary oscillation of inner sleeve or flexible, effectively reduces the situation that flexible tube leaks; And movable baffle ring can cooperate the rotation beat of inner sleeve and slide in guide groove, can not limit the action of inner sleeve, can increase the angle of inner sleeve beat.

Embodiment
The utility model provides a kind of servo-actuated leak stoppage structure of flexible tube, comprising an outer sleeve 10, is provided with the opening of at least one, and is provided with aprons slot 11 and guide groove 12 in opening; And inner sleeve 20, be arranged in the opening of outer sleeve 10; And cushion rubber 30, be located in the aprons slot 11 of outer sleeve 10; It is characterized in that establishing in guide groove 12 a movable baffle ring 21, this movable baffle ring 21 can slide in guide groove 12 with moving of inner sleeve 20, makes cushion rubber 30 can not lose the function of leakproof because of distortion.Below will know clearly and give explanation.
As shown in Figure 1, the utility model comprises: an outer sleeve 10 is provided with at least one opening, and is provided with aprons slot 11 and guide groove 12 in opening; Reach inner sleeve 20, one ends and be located in the opening of outer sleeve 10, the other end can connect other pipeline; And cushion rubber 30, be located in the aprons slot 11; It is characterized in that: be provided with movable baffle ring 21 in the guide groove 12 of outer sleeve 10, this movable baffle ring 21 can slide with the action of inner sleeve 20 in guide groove 12, the action of restriction cushion rubber 30 can effectively avoid cushion rubber 30 to produce the phenomenon of being out of shape with displacement because of the flexible rotation beat that reaches of inner sleeve 20.
Shown in Fig. 2～4, the pipeline that is connected when inner sleeve 20 is subjected to external force and does the time spent, inner sleeve 20 can produce action flexible and the rotation beat, this moment, movable baffle ring 21 can cooperate the action of inner sleeve 20, in the guide groove 12 of outer sleeve 11, slide, and cushion rubber 30 is limited in the aprons slot 11, cushion rubber 30 can not deformed because of the effect of inner sleeve 20 and displacement.
In sum, the utility model is to utilize movable baffle ring 21 to limit the mobile space of cushion rubber 30, makes cushion rubber 30 can cooperate the rotary oscillation of inner sleeve 20 or flexible, effectively reduces the situation that flexible tube leaks; And movable baffle ring 21 can cooperate the rotation beat of inner sleeve 20 and slide in guide groove 12, can not limit the action of inner sleeve 20, can increase the angle of inner sleeve 20 beats.
More than be this case illustrated embodiment, only establish that when the meaning that can not limit this case with this, promptly the listed various shift design of claim all should be included in the claim of this case for ease of explanation.
