Abstract

The utility model relates to a kind of rotary extension base, comprises an outer dish (1), an inner disc (2); Described inner disc lower wall (21) is rotatably connected by first (3) with outer dish lower wall (11); Outside the diameter of inner disc, outside on the dish dish (12) and outside coil and to comprise two or three second (4) between the lower wall (11); The upper end of described second (4) comprises one and inner disc (2) meshed gears (5); Go up one one end of arrangement and its fixing extension leg (6) in described second (4); There is an installation buckle (23) that is used to settle the support straight-bar in dish (22) central authorities on described inner disc; The beneficial effects of the utility model are: owing to adopt telescopic base, make and can accept in handling process, and in use can open, increase the surface of contact with ground; Can be applicable on fixed support or the straight-bar.

Description

The rotary extension base

Technical field

The utility model relates to a kind of base that supports weight, relates in particular to a kind of telescopic base.

Background technique

Support is used for putting object; In general, the weight ratio of carrying when the upper end is bigger, requires the base of lower end also bigger.Such as: in the hotel, places such as hotels, airport, we often can see the advertising framework that Gong the pedestrian that placed by businessman freely reads, and this contoured cradle is attractive in appearance, and available advertising message amount is big, cost is low, and overlayable wider, is subjected to liking of numerous businessmans.But also there are some problems in this support: because the weight ratio of upper end carrying is bigger, so need a bigger chassis to keep the stress balance of entire bracket.Though bigger domain provides stable support, also cause shelf heavier, be not easy to adjust position and carrying.

How to solve and can put heavy article, the area that can make base again is not too greatly that pendulum needs the problem that solves in face of the science and technology personnel.

Summary of the invention

The utility model technical issues that need to address have provided a kind of rotary extension base, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises an outer dish, an inner disc; Described inner disc lower wall is rotatably connected by first with the lower wall of outer dish; Outside the diameter of inner disc, outside on the dish dish and outside coil and comprise two or three second between the lower wall; Described second upper end comprises one and inner disc meshed gears; On described second, settle one one end and its fixing extension leg; There is an installation buckle that is used to settle the support straight-bar in dish central authorities on described inner disc;

Compared with prior art, the beneficial effects of the utility model are: owing to adopt telescopic base, make and can accept in handling process, and in use can open, increase the surface of contact with ground; Can be applicable on fixed support or the straight-bar.

Fig. 4 is that inside and outside dish passes through the gear engagement schematic representation among Fig. 3;

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

By Fig. 1, Fig. 2, Fig. 3, Fig. 4 as seen: the utility model comprises 1, one inner disc 2 of an outer dish; Described inner disc lower wall 21 is rotatably connected by first 3 with outer dish lower wall 11; Outside the diameter of inner disc, outside on the dish dish 12 and outside coil and comprise two or three second 4 between the lower wall 11; Described second 4 upper end comprises one and inner disc 2 meshed gears 5; On described second 4, settle one one end and its fixing extension leg 6; There is an installation buckle 23 that is used to settle the support straight-bar in dish 22 central authorities on described inner disc;

Described two or three second 4 to coil outside on 1 be symmetrical;

Described gear 5 has two screens;

The other end of described extension leg 6 has a pad pin 61;

The utility model comprises the device of three parts, i.e. the rotary plate device of being made up of inner disc and outer dish; The extension leg device of forming by spike (extension leg 6), rotating shaft (second 4) and interlock gear (gear 5); By install buckle that form with the connection set support straight-bar.

Spike is connected with outer dish by the rotating shaft that is fixed on the outer dish, and can rotate.The fixing of spike realized by the interlock gear that is installed on the outer dish.Have two fixing screens, one is the folding screens, and one for launching screens.

Inner disc is relative mobilizable with outer dish.By the rotation between inner disc and the outer dish, spike can launch thereupon and shrink, and fixes in two screens of interlock gear.

Diameter group is much smaller mutually with general base when closure for the utility model, but after spike launched, its deployment diameter can expand the weight of enough support entire bracket to; Owing to adopt the rotation spike to expand diameter, compare with original fixedly domain and weight reduction greatly.

The installation buckle of centre of the present utility model can be regulated, with support and the straight-bar that adapts to various sizes.The chassis is installed buckle by this and is connected with support, promptly becomes spendable support after the assembling.

The utility model has rubber feet at the end (free end) of spike, can the whole system support overhead have only the spike kiss the earth.
