Embodiment 1

[0033] Such as figure 1 As shown, the present embodiment provides a kind of chemical instrument for heating reaction that can be clamped and placed stably, including a base 1, an alcohol lamp 8 and a bracket 11, and also includes:

[0034] Clamping mechanism, the clamping mechanism is movably connected with the bracket 11, and is used for compressive positioning and clamping of the beaker. The clamping mechanism includes a driving part and a clamping part, and the clamping mechanism can be driven by the driving part The clamping part performs linear reciprocating motion to perform compression clamping and positioning of the beaker;

[0035] The height adjustment mechanism is movably connected with the base 1, and is used to push the alcohol lamp 8 to perform linear reciprocating motion. The height adjustment mechanism includes a screw rod A3, a power assembly and an adjustment assembly. The height adjustment mechanism can use power The component converts the rotary motion of ...

Embodiment 2

[0039] Such as Figure 1-3 As shown, this embodiment provides a chemical instrument for heating reaction that can be clamped and placed stably. As shown in Embodiment 1, the drive part includes a fixed seat 14, and a slot B20 is opened in the fixed seat 14. A pressure plate 28 is arranged in the slot B20, a pressure rod 23 is fixedly connected to the pressure plate 28, a spring 22 is fixedly connected between the pressure rod 23 and the inner wall of the slot, and a handle 15 is rotatably connected to the fixed seat 14, The handle 15 is fixedly connected with an eccentric wheel 24 in contact with the pressing rod 23, and the pressing plate 28 is in transmission connection with the clamping part;

[0040] Turn the handle 15 to drive the eccentric wheel 24 to press against the pressure plate 28. At this time, the pressure plate 28 performs linear reciprocating motion with the rotation of the eccentric wheel 24. The purpose of this setting is to drive the clamping part closer to ...

Embodiment 3

[0042] Such as Figure 2-3 As shown, this embodiment provides a chemical instrument for heating reaction that can be clamped and placed stably, as shown in Embodiment 1-2: the clamping part includes a fixed rod 21, and two groups of rods are symmetrically arranged on the fixed rod 21 Limiting columns 25, the limiting columns 25 are located on both sides of the pressure plate 28, and the fixing seat 14 is provided with a slot C that cooperates with the fixing rod 21;

[0043] The slot C is an arc-shaped slot or a V-shaped slot; there are through holes 26 and screw holes 27 at the end of the fixing seat 14 .

[0044] Two fixing rods 21 are arranged symmetrically with respect to the fixing seat 14 , and arc-shaped grooves are opened on the fixing rods 21 .

[0045] The pressure plate 28 drives the fixed rod to perform linear reciprocating motion along the fixed seat 14 through two sets of limit posts 25. The purpose of this setting is to approach or move away from the beaker thr...

Abstract

The invention discloses a chemical instrument capable of being stably clamped and placed and used for a heating reaction. The chemical instrument comprises: a base and a bracket; a clamping mechanism, which is movably connected with the bracket and is used for carrying out compression type positioning clamping on a beaker, wherein the clamping mechanism comprises a driving part and a clamping part, the clamping mechanism can drive the clamping part to do linear reciprocating motion through the driving part so as to clamp and position the beaker in a pressing manner; and a height adjusting mechanism, which is movably connected with the base and used for pushing an alcohol lamp to do linear reciprocating motion, wherein the height adjusting mechanism comprises a lead screw A, a power assembly and an adjusting assembly, and the height adjusting mechanism can convert rotary motion of the lead screw A into linear reciprocating motion of the adjusting assembly through the power assembly. With the chemical instrument, the beaker can be stably clamped, and the heating temperature of the alcohol lamp on the beaker can be controlled.

Description

technical field [0001] The invention relates to the technical field of chemical instruments, in particular to a chemical instrument for heating reaction which can be clamped and placed stably. Background technique [0002] The instruments used in chemical experiments are called chemical instruments. Chemical instruments can measure or react materials. Chemical instruments are mainly divided into measuring instruments and reaction instruments. Chemical instruments are combined in a specific way to form a device to achieve the purpose of the experiment. Beaker It is usually used as a reaction vessel when there is a large amount of reactants. In addition, it is also used to prepare solutions, accelerate the dissolution of substances, and promote the evaporation of solvents. There are many types and specifications of beakers. [0003] The clamping method of the existing heating reaction chemical instrument is basically to realize the clamping of the beaker by adjusting the cla...
