Description

The Muffle furnace fire door
Technical field: the utility model relates to a kind of box high temperature Muffle furnace fire door that Industrial Analysis, sintering and heat treatment are used that is used for.
Background technology: along with rapid economy development, people have paid attention to the usefulness and the security performance of the equipment that uses in all trades and professions more.And traditional Muffle furnace fire door function ratio is more single, is that single rotating shaft is opened the door or convertible opening the door with pulling out mostly, and the easy rotation of fire door when opening, and the fire door heating surface very easily makes the operator come to harm directly to the operator, causes security incident.
Summary of the invention: the utility model has changed the defective of traditional Muffle furnace fire door, provides a kind of switch to rotate nimbly and freely, parks steady and safe and reliable, durable Muffle furnace fire door.It comprises that fire door 5 flexibly connects body of heater 3, first support 1 and second support, 2 levels and the corresponding up and down upper and lower side that is fixedly connected on body of heater 3 one sides, first pivoted arm 4 flexibly connects first support 1 and fire door 5, second pivoted arm 6 flexibly connects second support 2 and fire door 5, the first pivoted arms 4 and second pivoted arm, 6 levels and corresponding up and down.Because the utility model has designed two centres of gyration, the double rocker mechanism fire door that four arms horizontally rotate rotates nimbly and freely stove door switch, parks steadily, cooperate accurately, and good airproof performance, and handling safety, reliability and durability.
Description of drawings: Fig. 1 is a front view of the present utility model
Fig. 2 is the vertical view of Fig. 1
The specific embodiment: shown in Figure 2 as Fig. 1: body of heater 3, by shell, insulation material and combustion chamber and heating system connects to form and fire door 5 flexibly connects, play heating and seal.First support 1 and second support, 2 levels and up and down correspondence be fixedly connected on body of heater 3 one side upper and lower sides, first pivoted arm 4 flexibly connects first support 1 and fire door 5, second pivoted arm 6 flexibly connects second support 2 and fire door 5, the main fire door that rises is along two centres of gyration, four arms horizontally rotate, utilize double rocker mechanism to make fire door and fire door face and stokehold panel remain horizontal level, fire door can rotation, makes the heating face that carries operator's the effect dorsad all the time of fire door.The middle and lower part of fire door 5 is provided with handle 7, works to draw back and close fire door.
During operation, the pulling handle, fire door is by first pivoted arm and second pivoted arm, with first support and second support is that the centre of gyration horizontally rotates, fire door and fire door face and stokehold panel remain parallel position, but fire door can rotation, and the heating face that carries that makes fire door is operator dorsad all the time.Material is put into and taken out, close fire door and get final product.
