Description

Industrial furnace door pressing mechanism

Technical Field

The utility model relates to an industrial furnace, in particular to a pressing mechanism suitable for a furnace door of an industrial furnace.

Background

The industrial furnace is very commonly used, but the furnace door of the industrial furnace generally has the condition of poor confidentiality, the production efficiency of the industrial furnace can be seriously influenced, and the energy consumption is high. The sealing strip is added on the furnace door, the condition that the furnace door is not tightly sealed can be improved in a short time, but the sealing strip is easy to age and crack after long use, and the phenomenon of furnace door crack leakage still occurs. Therefore, how to effectively ensure the sealing of the furnace door of the industrial furnace at low cost is a technical problem which needs to be solved at present.

Disclosure of Invention

The utility model aims at designing a rational in infrastructure, excellent in use effect's industrial furnace door hold-down mechanism.

The technical scheme of the utility model is, an industrial furnace door hold-down mechanism, it includes the handle bar, its characterized in that: a bracket is arranged on one side of the furnace door, a hinge seat is respectively arranged on the upper part and the lower part of the bracket, a hinge shaft of the upper hinge seat is fixedly connected with an upper crank, the outer end of the upper crank is rotatably connected with a synchronous connecting rod, and the inner end of the upper crank is fixedly connected with an upper pressing block; the articulated shaft of articulated seat has linked firmly down the crank down, and lower crank outer end rotates and is connected with synchronous connecting rod, and lower crank inner links firmly down the compact heap, and lower crank's middle part links firmly the handle pole.

The pressing block is L-shaped.

The surface of the pressing block contacting with the furnace door is provided with raised grains.

The utility model has the advantages that: simple structure, convenient to use can compress tightly the furnace gate of industrial furnace fast, and the switching is rapid.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The embodiments are described in detail in connection with the above drawings,

a hold-down mechanism of an industrial furnace door comprises a handle bar 8, a bracket 2 is arranged on one side of a furnace door 1, an upper hinge seat 4 and a lower hinge seat 10 are respectively arranged above and below the bracket, a hinge shaft of the upper hinge seat is fixedly connected with an upper crank 3, the outer end of the upper crank is rotatably connected with a synchronous connecting rod 6, and the inner end of the upper crank is fixedly connected with an upper hold-down block 5; the articulated shaft of the lower articulated seat is fixedly connected with a lower crank 7, the outer end of the lower crank is rotatably connected with a synchronous connecting rod, the inner end of the lower crank is fixedly connected with a lower pressing block 9, and the middle part of the lower crank is fixedly connected with a handle rod; the pressing block is L-shaped, so that the contact area of the pressing block and the furnace door is increased; the surface that compact heap and furnace gate contact be equipped with the raised grain, prevent the slippage, pressure conduction is better.

The utility model discloses utilize synchronous connecting rod, realized the control to the upper and lower compact piece in the furnace gate outside, can also set up several groups as required according to the use, further promote the degree of sticising to the furnace gate, guaranteed the sealed effect of furnace gate.

The above examples are merely illustrative for clarity and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. It is not necessary or necessary to exhaustively enumerate all embodiments herein, and obvious variations or modifications can be made without departing from the scope of the invention.

Claims
