Description
The utility model relates to a kind of improved fixed structure of telescopic pipe.
At present owing to stress compact modern society, wish that all various article are not when using, can dwindle the volume of its collection, therefore various dwindling uses the constructional device of article volume to keep up a steady flow of, use for the Consumer, the flexible pipe structure of often doing the handle use is one of them, please cooperate consult shown in Figure 5, it has the bigger hollow in a circle footpath and is responsible for A, less hollow looped pipeline B wears for a circle footpath, establish a block cannula C in the end of looped pipeline B, support the end of looped pipeline B in being responsible for A with retaining and deviate to be responsible for A, and end is passed by vacancy among the locating sleeve D that is sheathed on the person in charge A in addition, this locating sleeve D establishes profile groove D1 in the outstanding A end of being responsible for, this end portion is slit into several clamping plate D2, be provided with outside thread in each clamping plate D2 outer rim, establish for a packing sleeve pipe E spiral shell that has relative internal thread and be the hollow sleeve tubulose, by screw-thread fit between this packing sleeve pipe E and clamping plate D2, make each clamping plate D2 inwardly clamp the looped pipeline B outer rim of passing, make the master by packing sleeve pipe E, looped pipeline A, B can be fixed on this flexible position.
Yet, though said structure can make whole suitable the elongating or shortening of length, and fix its flexible state, still have disappearance on its structure, cause the inconvenience in the use.Such as:
1, packing operation inconvenience: because it is the action that forms packing with the screw-thread fit between packing sleeve pipe E and clamping plate D2, it must rotate packing sleeve pipe E certain clamping plate D2 is inwardly pushed in a few rears and grip looped pipeline B, cause the inconvenience of packing operation, and the prolongation of operating time, relative, in the time of adjusting, must impose the reverse order operation, inconvenience when having packing and temporal waste, very uneconomical.
2, worm structure easily is damaged: owing to be form with screw-thread fit between packing sleeve pipe E and clamping plate D2, the operator is for improving the effect of its whole packing, power commonly used screws this packing sleeve pipe E, so often make the screw thread between packing sleeve pipe E and clamping plate D2 be subjected to unusual strength and cause destruction, not only reduce the effect of its packing location, even can't continue again to use, must change or abandon, cause the waste on the user cost.
The purpose of this utility model promptly provides a kind of impaired telescopic pipe improved fixed structure of being convenient to operate and be difficult for.
For achieving the above object, the utility model is by pipe, position outer tube in the location, the flexible looped pipeline and the flexible person in charge constitute, the Guan Yiduan body is offered a L shaped profile groove in the location, with the profile groove is the boundary, and half tube wall is set as isometrical tube wall, and second half then forms the progressive tube wall that joins into a terrace with isometrical tube wall, and hold external rings to establish bulge loop in addition in body, insert engaging to form a projection in inside for flexible person in charge with groove opposite; Position outer tube then makes its hollow tube body form isometrical tube wall of semicircle and the progressive tube wall of semicircle, and both jointing places also form terrace, and body holds inside to establish a circular groove in addition; Thus, position outer tube is sheathed in the interior pipe in location, and the circular groove embedding that makes position outer tube is tied on the bulge loop of pipe in the location, and more small-bore flexible looped pipeline is located in the interior pipe in location, utilizing position outer tube to revolve moves, with its progressive tube wall compress the progressive tube wall of pipe in the location and packing flexible in pipe, reach the effect that causes fixed length.
After adopting said structure, the utility model directly utilizes two progressive tube walls to compress the face packing and fixes, and is easy to operate, and can be not destroyed during two terrace packings, can use for a long time, reduced use cost.
The utility model is described in further detail below in conjunction with accompanying drawing and example.
Fig. 1 is the utility model three-dimensional exploded view;
Fig. 2 is the utility model constitutional diagram;
Fig. 3 unscrews schematic representation for the utility model;
Fig. 4 screws schematic representation for the utility model;
Fig. 5 is a structural representation of commonly using telescopic pipe.
As shown in Figure 1, the utility model comprises a location inner tube 1, a location outer tube 2, a flexible looped pipeline 3 and 4 formations of a flexible person in charge.
Wherein: location inner tube 1 is a hollow tube, can be arranged in the position outer tube 2 and for flexible looped pipeline 3 and place, its body one end ring wall is offered a L shaped profile groove 11, and take profile groove 11 as the boundary, the one side is made as an isometrical tube wall 12, side then forms a progressive tube wall 13 in addition, and at the outside terrace 14 that forms of the body of the two junction; In addition, inner tube 1 another end outside, location is convexly equipped with a bulge loop 15, and forms a projection 16 in the end inner face; Position outer tube 2 is a hollow tube, suitable can being placed on the above-mentioned location inner tube 1, play rotation control degree of tightness, the inner semicircle of its body is set as an isometrical tube wall 21, another semicircle then forms the progressive tube wall 22 that thickens one by one by isometrical tube wall 21 1 ends, and cause isometrical tube wall 21 another ends and 22 handing-over of progressive tube wall to hold also tool one terrace 23, and in addition, the inner circular groove 24 that forms of position outer tube 2 another ends; Flexible looped pipeline 3 is a suitable long tube body, and its bore is littler, can be arranged in the hollow tube of location inner tube 1, has to prolong and the purposes that shortens length; The flexible person in charge 4 can be plugged in the end that location inner tube 1 has projection 16, offers a groove 41 on its opposite end tube wall, and two sides are extended number projection 42 in the notch of groove 41.
As shown in Figure 2, during the utility model combination, will locate inner tube 1 and be arranged in the position outer tube 2, the bulge loop 15 of location inner tube 1 is embedded on the circular groove 24 of position outer tube 2 inside, makes its two noose location; The flexible person in charge 4 then is plugged in an end that has projection 16 in the inner tube 1 of location with its end with groove 41, and fastens projection 16 by the projections 42 in the groove 41, and its flexible 4 difficult again row of being responsible for are deviate from; The flexible looped pipeline 3 that bore is littler is arranged in the inner tube 1 of location again, and it also can stretch into flexible person in charge in 4; And as shown in Figure 3, when position outer tube 2 and the dual terrace surface 14 of locating inner tube 1,23 only supported mutually, its position outer tube 2 was inwardly oppressed location inner tube 1, and its two tube wall becomes a loose fit, and the free-extension displacement in locating inner tube 1 of flexible looped pipeline 3 can be provided.
In addition, slightly revolve when moving position outer tube 2 when little, as shown in Figure 4, make the progressive tube wall 22 of position outer tube 2 inside inwardly compress the progressive tube wall 13 of location inner tube 1, the flexible looped pipeline 3 of these progressive tube wall 13 micro-deformation packings that distinguished by L-type profile groove 11 reaches the effect of fixing flexible looped pipeline 3; Otherwise, when oppositely unscrewing position outer tube 2, its with the relative tube wall of location inner tube 1 loose fit, make the flexible looped pipeline 3 in it freely stretch length, reach degree of tightness processing ease and location and have a definite purpose.
