Embodiment 1

[0018] see figure 1 , a multifunctional universal safety experiment support, comprising a tie rod 2 with a base 1, a fixed rod 4 fixed on the tie rod 2 by a clamping screw 3 and a first ring 5 fixed on the fixed rod 4, Also comprising a second ring 6 and a third ring 7, wherein the outer diameter of the second ring 6 is smaller than the inner diameter of the first ring 5; the outer diameter of the third ring 7 is smaller than the inner diameter of the second ring 6 . The second circular ring 6 is movably connected on the first circular ring 5 by two movable pins 8, so that the second circular ring 6 and the third circular ring 7 can swing relative to the first circular ring 5 with the movable pin 8 as a fulcrum, so that A universal ring structure is formed between the first circular ring 5 , the second circular ring 6 and the third circular ring 7 . Two movable pins 8 are arranged at 180 degrees on the first circular ring 5 and the second circular ring 6 .

Embodiment 2

[0022] see image 3 , a multifunctional universal safety experiment bracket, a fourth ring 10 is arranged between the second ring 6 and the third ring 7, the diameter of the fourth ring 10 is smaller than the diameter of the second ring 6, but larger than the diameter of the second ring 6 The diameter of the three rings 7. The fourth ring 10 is fixedly connected with the connector 14, and three screw holes are evenly distributed on the ring wall of the fourth ring 10, and a set screw 11 is screwed through each screw hole, and the rest of the structure is the same as that of the first embodiment.

[0023] see Figure 4 , during the experiment, first place an asbestos net 11 on the third ring 7, then place the beaker 12 on the asbestos net 12, rotate the three set screws 11 inwardly, and the three set screws 11 will stand on the On the cup wall of beaker 13, beaker 13 is clamped. Like this, no matter the fixed rod 4 is not clamped firmly, or it is tilted due to accidental rea...

Abstract

The invention discloses a multifunctional universal safety experiment bracket, which comprises a fixed rod fixed on a tie rod through a clamping screw and a first circular ring fixed on the fixed rod. The bracket is characterized in that the bracket also comprises a second circular ring and a third circular ring; the second circular ring and the third circular ring are connected through a connecting piece; the second circular ring is movably connected with the first circular ring through two movable pins, so as to ensure that the second circular ring and the third circular ring can swing relative to the first circular ring by taking the movable pins as fulcrums; a fourth circular ring is arranged between the second circular ring and the third circular ring; a plurality of holding screws which are screwed in or out are arranged on the wall of the fourth circular ring; and the holding screws are used for clamping a built-in beaker. No matter whether the fixed rod is not firmly clamped or is inclined due to accidental causes, the bracket can always ensure that an alcohol lamp is vertical and can not be overturned or spill alcohol, and can ensure that heated containers can not be overturned, so as to ensure experiment safety.

Description

technical field [0001] The invention relates to an experimental support for chemical experiments, in particular to a multifunctional universal safety experimental support. Background technique [0002] In traditional chemical experiment equipment, the chemical instrument support usually includes a base, a tie rod vertically fixed on it, and an experimental support fixed on the tie rod by clamping screws. Generally speaking, the experimental support includes a fixed rod and a ring fixedly connected with the fixed rod, and the ring is used to support chemical instruments, such as beakers, crucibles, Erlenmeyer flasks and the like. In scientific experiments, alcohol lamps are often used to heat chemical instruments. Since each chemical experiment device is different, the height of the position where the alcohol lamp should be placed is also different, and multiple wooden blocks are often used to raise it. This is both inconvenient and unsafe. [0003] Korean Utility Model Pub...
