Multiple linked damper mechanism for smoke discharging cabinet

Abstract

The present invention aims to design a multi-connected regulating door mechanism for smoke exhaust cabinets, which can be composed of a plurality of regulating doors side by side. Each regulating door is connected to its own counterweight box through a cable and pulley device. A movable guide rail that exceeds the height of the adjustable door is combined with a shorter fixed guide rail on the cabinet body, and the movable guide rail is slidably embedded on the fixed guide rail. The multi-connected regulating door mechanism for smoke exhaust cabinets of the present invention can not only independently operate and lift each regulating door without being restricted by the position of other regulating doors, but also makes the entire unit The operation opening of the fume hood is connected and open, which can meet the needs of putting large experimental equipment in the fume hood for experiments.

Description

technical field [0001] The invention relates to a multi-connected regulating door mechanism for a fume exhaust cabinet. Background technique [0002] Figure 1a Shown is the structural diagram of the existing single-adjusting door smoke exhaust cabinet, which is mainly composed of a cabinet body 1', a balance weight 2', a pulley block 3', a steel cable 4', an adjusting door 5', and a track 6'. The pulley blocks 3' on both sides of the cabinet body 1' are respectively provided with a steel cable 4' and one end of the steel cable 4' is connected with the balance counterweight 2', and the other end is connected with the bottom of the adjusting door 5'. The pulley block 3' is responsible for the support and steering work of the steel cable 4'. When the balance weight 2' rises, the adjusting door 5' connected to the other end of the steel cable 4' is relatively lowered along the track 6'. When the adjusting door 5' rises along the track 6', the balance weight 2' connected to the...

Problems solved by technology

[0005] The above-mentioned multi-door smoke exhaust cabinet solves the need to put multiple experimental equipment in the cabinet for experiments at the same time, but it is more difficult to put in large-scale experimental products

Because there is a partition center column between the two adjustment doors, unless the large-scale experimental equipment is a soft item that can be placed in the cabinet, general rigid or hard items cannot be placed at all due to the existence of the partition center column, so this traditional The multi-adjustable door fume hood cannot meet the needs of large-scale experimental equipment
