Abstract

A tripod, which consists of a connecting ring at the top and three legs that are fixed on the connecting ring, wherein each leg unit is composed of a set of legs in socket joint where the lowest leg is provided with a foot at the bottom; the outer face of each leg is provided with a group of axial prominent ribs, while an axial concave sliding chute is arranged at a proper position on the inner face; a transversal concave sliding chute is arranged at the upper end of each inner leg. When put into use, draw each inner leg out one by one, and when reaching the transversal concave sliding chutes, turn the inner legs transversally and the tripod can provide firm support; when the prominent ribs of the inner legs are aligned with the prominent ribs of the outer legs, the inner legs can be inserted into the outer legs. Of a simple and rational structural design, the utility model is convenient and reliable to use.

Description

A kind of three-legged support

The utility model relates to a kind of three-legged support.

The three-legged support of the usefulness that is easy to carry at present, its each flexible rack leg generally all is that be equipped with can be by the shell fragment that advances or being used to of upspringing play fixed supporting role after pulling out in the leg upper end under support, be not difficult to infer: this three-legged support is stable inadequately, bracing force is not enough, Applicable scope is little, owing to need additional shell fragment, not only cost is high and influence allomeric function because of easily coming off.

The purpose of this utility model provides a kind of sturdy construction, durable, three-legged support that using effect is good.

For achieving the above object, the utility model is taked following design proposal: this three-legged support is made up of top fastener rings and three rack leg unit fixed thereon, described rack leg unit is to be pegged graft by fit inside and outside the plural rack leg to constitute, the rack leg bottom of lowermost end is equipped with stent foot, one group of axial projection muscle is arranged on each rack leg exterior edge face, recessed slideway is arranged on the interior edge face corresponding position, and there is the chute of transverse recess the upper end of each inner support leg.

Connect by connection set between described top fastener rings and rack leg unit, this connection set comprises that one is fixed on the fixed block on the fastener rings of top, one is fixed on the revolving part of upper end, rack leg unit, fixed block interconnects end with revolving part and goes up the corresponding attachment hole that passes for coupling shaft that has, and revolving part is connected with fixed block by coupling shaft and can rotates around it.

The affixed ball formula cover body in the exterior edge face of top fastener rings, in conjunction with constituting, second ball cover lower side has for three three inverted U-shaped space groove that the rack leg unit is opened or regained this cover body by upper and lower two halves ball cover.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 7 is another example structure schematic representation of the utility model

As shown in Figure 1, the utility model three-legged support, it is made up of top fastener rings 1 and three rack leg unit fixed thereon, described rack leg unit is to be pegged graft by plural rack leg 2 mutually inside and outside fits to constitute, the rack leg bottom of lowermost end is equipped with stent foot 3, connect by connection set between top fastener rings and three rack leg unit, this connection set comprises that one is fixed on the fixed block 4 on the fastener rings of top, one is fixed on the revolving part 5 of three-legged support, and revolving part is connected with fixed block by coupling shaft and can rotates around it.

As Fig. 2, shown in Figure 3, one group of (three for good) axial projection muscle 201 is arranged on described each rack leg 2 exterior edge face, there is recessed slideway 202 the corresponding axial orientation of inner face appropriate position, this recessed slideway can be whole section, or be local segment, be located at port position place, lower end and be advisable, realization that can assurance function is reduced friction again as far as possible.

As shown in Figure 4, there is the chute 203 of transverse recess the upper end of each inner support leg.

Above-mentioned inner support leg is for the rack leg of its overcoat.

Fig. 5, Fig. 6 are the utility model fixed block, revolving part structural representation.

Between fixed block and revolving part, rubber ring is housed, makes rack leg fixed-site when opening and regain.

For in use; increase the aesthetic feeling of outward appearance and protect interconnect; can be in the exterior edge face of top fastener rings an affixed ball formula cover body 6; in conjunction with constituting, second ball cover lower side has for three three inverted U-shaped space groove 6021 (referring to Fig. 7) that the rack leg unit is opened or regained this cover body by upper and lower two halves ball cover 601,602.

During assembling, the raised ribs of inner support leg places in the recessed slideway of support arm leg.

During use, draw back the inner support leg successively and to the runner position of the transverse recess of upper end, laterally rotate, get final product firm support; During withdrawal the raised ribs of inner support leg being aimed at support arm leg upper lobes muscle pushes.

The utility model has the advantage of: the structural design advantages of simple, easy to use and reliable.
