Specific implementation mode

As shown in Fig. 1,3,4, a kind of one of which specific embodiment of adjustable funnel stand, including vertical pole 1, sleeve 2, adjustment barrel 3 and funnel circle 4, the bottom of strut are welded with pedestal, make strut straight up, for fixing stop sleeve and funnel Circle.The sleeve 2 is sleeved on the strut 1, and the top surface of the sleeve 2 is molded that there are three extruding plate 5, three institutes along wall surface upwards It states extruding plate 5 to be uniformly arranged in the circumferential direction, when three extruding plates being made to squeeze to centre, extruding plate is pressed on strut, prevents sleeve from existing It is moved up and down on strut, plays the role of adjusting upper and lower position.It is sleeve 2 specifically to squeeze the mode of three extruding plates Upper end peripheral surface form external screw thread；The press section 301 of the adjustment barrel 3 including top and lower part screw portion 302, described Press section 301 screws the integrated molding of portion 302 with described, the inner peripheral surface for screwing portion 302 form with it is outer on the sleeve 2 The cavity shape of the internal thread that screw thread matches, the press section 301 is the frustum of a cone, and the round mouth diameter of upper end is less than the circle of lower end Mouth diameter, adjustment barrel is inserted in above sleeve, is screwed portion and is coordinated by screw thread and sleeve, the process that press section moves down In, due to press section inner cavity upper end round mouth be less than lower end round mouth, so extruding plate under the action of press section gradually to centre It squeezes, to be pressed on strut, prevents sleeve from moving up and down.

As shown in Fig. 1,2,5,6, it is open loop knot that the lower end horizontal connection of the sleeve 2, which has the funnel circle 4, funnel circle 4, Structure, in particular plastic material, separated annulus in being form upper rack 6 on one of end, on another end Lower rack 7 is formed, the upper rack 6 and lower rack 7 are inserted into fixed frame 8, and upper rack 6 and lower rack 7 are oppositely arranged.Institute It states 8 outside of fixed frame and knob 10 is rotatably mounted with by rotary shaft 9, the rotary shaft 9 penetrates fixation from 8 side wall of fixed frame Inside frame 8, gear 11 is fixed in rotary shaft 9, i.e. rotary shaft is penetrated from the side wall of fixed frame, and tooth is fixed inside fixed frame Wheel, the fixed knob outside fixed frame make knob be rotated with gear synchronous.The gear 11 be located at upper rack 6 and lower rack 7 it Between, and engaged with upper rack 6 and lower rack 7, as the knob, gear rotation makes upper rack and lower rack simultaneously to contracting Tight or dimension movement, to realize the big minor adjustment of funnel circle.Scale 13 is decorated in 4 upper surface of funnel circle, according to solid Determine frame and the position on funnel circle, the diameter for marking funnel circle at this time in the position, enables a person to leak according to clear read Struggle against the diameter enclosed, and fixed frame is easily moved to the diametrical position of needs.

As shown in Figure 1, in addition to above-mentioned technical characteristic, spacer sleeve is equipped with multiple rubber rings 12 on the funnel circle 4, this is specific Three rubber rings are arranged in embodiment on funnel circle, when making placement funnel, are more stablized, and prevent plastic funnel circle from damaging glass Funnel.

Embodiment described above is only that the preferred embodiment of the utility model is described, not to the utility model Range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are new to this practicality The various modifications and improvement that the technical solution of type is made should all fall into the protection domain of the utility model claims book determination It is interior.
