Abstract

The utility model relates to a universal expanding rod. One end of an outer tube is sheathed with an inner tube which is provided with an eccentric wheel. The other ends of the inner tube and the outer tube are fixedly provided with screw plugs respectively. The screw plugs and a fine adjustment coil are in threaded connection. The other end of the fine adjustment coil is connected with a globe body of a universal supporting base. The universal supporting base is composed of a rubber basin sucking base and the globe body which is inlaid inside and can slide freely. When the rubber basin sucking base is pressed and contacted with a wall surface, the globe body thereof which is connected with the expanding rod can rotate freely in a plurality of directions. The disadvantage of a one-way expanding rod is overcome. In addition, a bearing shape is also formed on the inner wall of a concave cavity of the globe body for reducing the frictional force of rotation when fine adjusted. A convex circular shape is formed at the bottom of an inner cavity. So the operation is convenient, and the universal expanding rod is very practical.

Description

The universal bar that rises

The utility model relates to a kind of universal bar that rises, and more particularly it is a kind of strut of displacement, can not only rectilinear direction supports, and can change the bar that rises that direction and angle support.

Improvement along with people's living conditions, the home decoration articles for use are also more and more rich and varied, various " bar rises " and " Adjustable length rod " successively occur, and brought a lot of convenience to people, but deficiency is also arranged, can only be in two face wall upper supports of opposition, but Modern Interior Decoration often need strut on the corner, so that hang a little article, this is the existing on the market at present unidirectional bar that rises, or Adjustable length rod can't satisfy.

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art and a kind of universal bar that rises is provided, and it can not only parallelly support, and vertical support, and can also universally supporting that is to say and can also support sideling, and askew support is in the corner upper support.

The purpose of this utility model is achieved in that a kind of universal bar that rises of design, one of the end socket of outer tube be provided with eccentric in pipe, the other end at inner and outer pipe respectively is fixed with plug screw, plug screw is threaded with the fine setting screwed pipe, it is characterized in that the other end of finely tuning screwed pipe is connected with the spheroid of universal support seat.Above-mentioned universal support seat be by rubber inhale the basin seat and be embedded in the spheroid that is free to slide constituted, an end of fine setting screwed pipe is the cavity of the cover spheroid of filling in universal support and connecting.

During use, rubber is inhaled the basin seat to be overlayed on metope, spheroid is wherein connecting the bar that rises and can freedom rotate in many ways, and coarse adjustment is to move interior pipe and outer tube to suitable length, then pipe in the rotation, because the eccentric wheel of interior Guan Yiduan tightly is locked in the inwall of outer tube, play the friction pressuring action, tentatively fixed the length of the bar that rises, regulate the fine setting screwed pipe again, the length of bar of rising that extended plays the effect of fine setting.And the strength that overlays wall of having reinforced rubber suction basin on the universal bar that rises, also strengthened simultaneously the load force of bearing, laborsaving when finely tuning for making, avoid part and wall impaired, the utility model also designs a kind of scheme, is exactly on the spheroid of universal support seat, on the inwall of its cavity that is connected with the fine setting screwed pipe, constitute the bearing shape, and be in the bottom of cavity have one protrude circular, alleviate spin friction power.

The utility model has improved the deficiencies in the prior art part greatly owing to adopt above measure, has enlarged using scope, processing ease, and strength is big, is difficult for landing, does not damage metope.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a structure sectional view of the present utility model;

Fig. 2 is the spheroid sectional view of universal support seat;

Fig. 3 is the A-A sectional drawing of Fig. 2.

Among the figure: 1, outer tube 2, eccentric wheel 3, interior pipe 4, plug screw 5, fine setting screwed pipe

6, spheroid 7, rubber are inhaled basin seat 8, are blocked circle 9, bearing shape

10, circular

In Fig. 1, one end of interior pipe (3) is fixed with an eccentric wheel (2), pack into an end of outer tube (1) simultaneously, the other end at inner and outer pipe (3,1) respectively is fixed with plug screw (4), plug screw (4) is threaded with fine setting screwed pipe (5), the other end cover of fine setting screwed pipe (5) fill in universal support seat spheroid (6) cavity and connect into.This spheroid is to be embedded in the universal support seat, can be free to slide, the other end of universal support seat then is that rubber is inhaled (7) at the bottom of the basin, can be squeezed on the wall, difficult drop-off, the frictional force of rotation when finely tuning in order to reduce also can constitute bearing shape (9), and be formed with circular (10) of protruding in the bottom of cavity on the inwall of the cavity that spheroid is connected with the fine setting screwed pipe.

Claims

1, a kind of universal bar that rises, one of the end socket of outer tube be provided with eccentric in pipe, respectively be fixed with plug screw at the other end of inner and outer pipe, plug screw is threaded with the fine setting screwed pipe, the other end that it is characterized in that finely tuning screwed pipe is connected with a universal spheroid that supports.

2, the universal bar that rises according to claim 1 is characterized in that described universal support seat is to be inhaled the basin seat and be embedded in the interior spheroid that is free to slide by rubber to be constituted.

3, the universal bar that rises according to claim 1, the cavity that the end cover that it is characterized in that described fine setting screwed pipe is filled in the spheroid of universal support seat connects.

4, the universal bar that rises according to claim 1 is characterized in that the spheroid of described universal support seat, its with cavity inwall that the fine setting screwed pipe is connected on formation bearing shape, and be formed with the circular of a protrusion in the bottom of cavity.
