Problems solved by technology

But above-mentioned this double adjusting door can not be linked when moving up and down, must just can drive upper adjusting door 24 ' to move together when lower adjusting door 23 ' moves to rising or falling limit, not flexible enough
In addition, this traditional double adjustment door needs two balance counterweights 21', 22' to adjust the balance problem when the two adjustment doors rise or fall respectively, so when moving the double adjustment door to a certain height, it is necessary to apply force to it at the same time. Two sets of balanced counterweights, and when the upper flange of the lower adjustment door touches the upper flange or lower flange of the upper adjustment door, if the speed is faster, an impact will occur, which will easily cause structural damage to the adjustment door in the long run

Embodiment Construction

[0027] As shown in Figures 3 to 6, the linked double-adjusting door mechanism for the fume exhaust cabinet of the present invention includes guide rails 9 arranged on the left and right sides of the fume exhaust cabinet 1, which are respectively slidably embedded on the corresponding guide rails The upper regulating door 2 and the lower regulating door 3, the pulley mechanism composed of the left pulley group 4, the right pulley group 5, and the movable pulley group 6, as well as the steel cable 7 and the counterweight box 8.

[0028] The upper regulating door 2 and the lower regulating door 3 can slide up and down freely along the guide rails 9 at both ends of the fume extractor 1 respectively. The left and right bottom ends of the upper regulating door 2 are respectively connected to two steel cables 7a and 7b, and the left and right bottom ends of the lower regulating door 3 are respectively connected to the other two steel cables 7c and 7d. The rising and falling of the steel ...

Abstract

The present invention aims to design a linkage type double-adjustment door mechanism for a smoke exhaust cabinet, including: a smoke exhaust cabinet, a pulley mechanism, several steel cables, a counterweight box, an up and down adjustment door and guide rails. The two sides of the upper and lower adjustment doors are connected to a counterweight box through their own steel cables through the pulley mechanism, so that the upper and lower adjustment doors can produce a double-door linkage movement effect with a stroke ratio of 1:2, and can achieve positioning at the same time.

Description

Technical field [0001] The invention relates to a linkage type double regulating door mechanism for a fume exhaust cabinet. Background technique [0002] figure 1 Shown is the structural diagram of the existing smoke exhaust cabinet with a single adjustable door, which is mainly composed of a cabinet 11', a balance weight 12', a pulley block 13', a steel cable 14', an adjustable door 15', and a rail 16'. The pulley blocks 13' on both sides of the cabinet 11' are each provided with a steel cable 14', and one end of the steel cable 14' is connected to the balance weight 12', and the other end is connected to the bottom of the regulating door 15'. The pulley block 13' is responsible for the support and steering of the steel cable 14'. When the adjusting door 15' rises, the balance weight 12' connected to the other end of the steel cable 14' will relatively descend along the rail 16'. When the adjusting door 15' descends along the track 16', the balance weight 12' connected to the ...
