Abstract
The utility model discloses a door closer for a vacuum furnace. The door closer is characterized in that the vacuum furnace comprises a furnace body and a furnace cover. An internal furnace body flange is arranged between the furnace cover and the furnace body, one end of the internal furnace body flange stretches out of the side face of the furnace body, a lever unit parallel with a furnace body axis is movably connected on an end portion, one end of the lever unit is movably connected with an air cylinder which is fixedly connected on one side face of the furnace body, and the other end of the lever unit uses a clamp structure snapping the upper end face of the furnace cover. The furnace cover is opened and closed through the lever unit and the air cylinder arranged on the side face of the furnace body, and the snapping and loosening of the other end of the lever unit and the furnace cover is achieved by controlling the stretching and the withdrawing of an air cylinder stretching rod.
Description
Technical field
The utility model relates to a kind of vacuum drying oven door closer, especially a kind of vacuum drying oven door closer simple in structure.
Background technology
Present vacuum drying oven closes a mechanism roughly two kinds, a kind ofly realize filling barotropic gas, it generally all adopts the retainer structure, retainer is designed to sawtooth pattern, roller is installed on the retainer, the rotation that relies on cylinder to promote retainer realizes automatically opening or closing, and the shortcoming of this mechanism is to make complexity, and cost compare is high.Another kind is the vacuum drying oven that does not need in the stove with malleation, and at present general what adopt is 4 handwheels in conjunction with the snap ring form of rotational lock separately, although this method manufacturing cost will be hanged down a bit, can't realize automatically complex operation.Based on above shortcoming, this utility model is a kind of both simple, can realize again the door lock of autoshutdown and unlatching, and manufacturing cost also reduces greatly.
The utility model content
Technical problem to be solved in the utility model provides a kind of vacuum drying oven door closer, finishes the keying of fire door, and is simple in structure.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of vacuum drying oven door closer, its innovative point is: described vacuum drying oven comprises body of heater and bell, the inner furnace body flange is set between described bell and body of heater, described inner furnace body flange one end exceeds the body of heater side, and the leverage that is parallel to the body of heater axis in its end flexible connection one, described leverage one end is flexibly connected cylinder, described cylinder is connected in the body of heater side, the described leverage other end adopts fastening type structure, described fastening type structure interlock bell upper surface.
The utility model has the advantage of: the keying that utilizes the leverage be arranged on the body of heater side and cylinder to realize bell, by the stretching out and retract of control cylinder extension bar, the interlock of the realization leverage other end and bell and unclamping.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of vacuum drying oven door closer of the utility model.
The specific embodiment
Vacuum drying oven comprises body of heater 1 and bell 2 in a kind of vacuum drying oven door closer shown in Figure 1,1 of bell 2 and body of heater arrange inner furnace body flange 3, inner furnace body flange 3 one ends exceed body of heater 1 side, and the leverage 4 that is parallel to the body of heater axis in its end flexible connection one, leverage 4 one ends are flexibly connected cylinder 5, cylinder 5 is connected in body of heater 1 side, and leverage 4 other ends adopt fastening type structure 6, fastening type structure 6 interlock bells 2 upper surfaces.
The extension bar of the cylinder 5 by lever lever apparatus one end stretches out and retracts, thus the interlock of the fastening type structure of the lever lever apparatus other end 6 and bell 2 and unclamping.
In addition, calculate the thrust size of cylinder and the length of lever according to the required pressure in the stove during design of the active force of leverage, thus needed dynamics when providing the fire door compression.Owing to the effect of cylinder thrust and lever, determined the dynamics of bell closure, bell can produce bounce-back when surpassing the pressure of design in the stove, and bell i.e. automatically realization pressure release, has reduced the generation of security incident after the overvoltage in the stove.
