Abstract
The utility model discloses a flexible pipe fitting of multi -functional show shelf, including hollow outer tube and inner tube, the spiral shell twistlock that the one end of outer tube was provided with the locking inner tube tightly installs, locking device installs the nut including external screw member, the external screw member who sets firmly thread in the outer tube tip has outside, and protruding runner band platform in the shaping of external screw member inner wall whole has, the up end of runner band platform are the inclined plane, the protruding platform of fitting with a contraceptive ring in the whole shaping of the inner wall of nut has has been placed between the upper and lower ring platform and has been the tube -shape bush, and the bush lateral wall is equipped with the opening, because at the bush that is provided with of nut and inner tube, oppression through upper and lower ring pair of stations bush makes the bush compress tightly the inner tube towards the internal strain, has formed inner tube and bush, bush and external screw member's bump contact, and locking device's reliability has been improved to the design of this mechanics, in addition, owing to changed locking device's force -bearing mode, each part of spiral locking device can all adopt plastics injection processing, has reduced the cost of product.
Description
Technical field
The utility model relates to a kind of flexible pipe fitting of multifunctional demonstration stand.
Background technique
The structure of conventional display frame comprises framework, base, in order to reach bandwagon effect, generally be coated with advertisement painting canvas in the outside of framework, for exhibition needs, the framework of Show stand is all assembled by flexible pipe fitting, the flexible fitting structure of existing Show stand mainly comprises the outer tube of hollow and interior pipe, one end of outer tube is provided with the screw locking device of pipe in locking, screw locking device is made up of the external thread piece and lock nut with external screw thread, the top of external thread piece is generally the taper narrowed gradually, end opens has some flutings, in jaw shape, the end of the same seasonal jaw shape tightened up at nut is to entering distortion, thus interior pipe is locked.This external thread piece is generally metalwork, and not only cost is high, and the area of contact of jaw and interior visitor is less in locking process, poor reliability.
Summary of the invention
The technical problems to be solved in the utility model is to provide the flexible pipe fitting of low, the reliable and stable multifunctional demonstration stand of a kind of cost.
In order to solve the problems of the technologies described above, the flexible pipe fitting of a kind of multifunctional demonstration stand of the present utility model, comprise the outer tube of hollow and interior pipe, one end of outer tube is provided with the screw locking device of pipe in locking, described locking device comprises and is fixedly arranged on that outer tube end has the external thread piece of external screw thread, external thread piece is provided with nut, external thread piece inwall global formation has the lower land of convex, the upper-end surface of lower land is inclined-plane, the inwall global formation of described nut has the upper land of convex, be placed with between upper and lower land in tubular liner, lining sidewall is provided with opening; During installation, interior pipe passes from outer tube and lining, and while nut is rotated down, upper land presses down lining and makes the lower edge of lining inwardly tighten up along the inclined-plane of lower land, is locked by interior pipe.
Further improvement of the utility model, described lining has at least the outer rim of one end to offer inclined-plane.
Further improvement of the utility model, the lower end surface of described upper land is inclined-plane.
Further improvement of the utility model, the outer rim at described lining two ends offers inclined-plane.
Further improvement of the utility model, the bottom of described interior pipe is provided with flanging, and the maximum outside diameter of flanging is greater than the internal diameter of lower land.
The beneficial effects of the utility model are: owing to being provided with lining at nut and interior pipe, lining is made to manage in internal strain compresses by the compressing of upper and lower land to lining, define the bump contact of interior pipe and lining, lining and external thread piece, the design of this mechanics improves the reliability of locking device; In addition, owing to changing the force way of locking device, each parts of screw locking device can adopt plastic injection to process, and reduce the cost of product.In order to prevent interior pipe from easily deviating from, the bottom of interior pipe 2 is provided with flanging, and the maximum outside diameter of flanging is greater than the internal diameter of lower land.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of Show stand;
Fig. 2 is the decomposition texture schematic diagram of flexible pipe fitting;
Fig. 3 is the broken section structural representation of flexible pipe fitting;
Fig. 4 is the broken section decomposition texture schematic diagram of flexible pipe fitting.
Embodiment
Shown in Fig. 4, a kind of flexible pipe fitting of multifunctional demonstration stand, comprise outer tube 1 and the interior pipe 2 of hollow, one end of outer tube 1 is provided with the screw locking device of pipe 2 in locking, locking device comprises and is fixedly arranged on that outer tube 1 end has the external thread piece 3 of external screw thread, external thread piece 3 is provided with nut 4, external thread piece 3 inwall global formation has the lower land 31 of convex, the upper-end surface of lower land 31 is inclined-plane 32, the inwall global formation of nut 4 has the upper land 41 of convex, to be placed with in tubular liner 5 between upper and lower land 41,31, lining 5 sidewall is provided with opening 51; During installation, interior pipe 2 passes from outer tube 1 and lining 5, and while nut 4 is rotated down, upper land 41 presses down lining 5 and makes the lower edge of lining 5 inwardly tighten up along the inclined-plane of lower land 31, is locked by interior pipe 2.
Further, the outer rim at lining 5 two ends offers inclined-plane 52, the lower end surface of upper land 41 is similarly inclined-plane 42, in the process of nut 4, lining 5 inwardly tightens up distortion under the acting in conjunction on upper and lower land two inclined-planes like this, sleeve inner surface and interior tube-surface, between sleeve outer surface and the internal surface of external thread piece, form larger frictional force, further increase the reliability of locking.
In addition, for the ease of transporting and depositing, telescopic pipe pipe fitting is when unassembled use, internal tube shrinks is placed in outer tube, and in order to prevent interior pipe from easily deviating from, the bottom of interior pipe 2 is provided with flanging 21, the maximum outside diameter of flanging 21 is greater than the internal diameter of lower land 31, and interior pipe can not be deviate from.
The above be the utility model preferred embodiment, it does not form the restriction to the utility model protection domain, as long as realize the purpose of this utility model with substantially identical means all should belong to protection domain of the present utility model.
