Referring to fig. 1-2, a universal resistance furnace comprises a furnace body 1. The furnace body 1 is provided with a plate groove 11, a furnace plate 2 is placed in the plate groove 11, four side walls of the furnace plate 2 are mutually abutted with four inner walls of the plate groove 11, and the furnace plate 2 slides in the plate groove 11. The upper surface of the stove plate 2 is provided with a containing groove 21, and the heating wire 22 is placed in the containing groove 21. The front side wall of the furnace body 1 is provided with a switch 12 for controlling the on-off of the heating wire 22. An electric push rod 3 is arranged below the furnace plate 2, and an output shaft of the electric push rod 3 is fixedly connected with the lower surface of the furnace plate 2. When the furnace is in a working state, the upper surface of the furnace disc 2 is higher than the upper surface of the furnace body 1; when switch 12 disconnection, electric push rod 3 drive stove dish 2 downstream makes the upper surface of stove dish 2 be less than the upper surface of furnace body 1, reduces the staff and miss the risk that touches stove dish 2 and cause the scald after closing switch 12.

The furnace body 1 is internally provided with two blocking devices 4, the two blocking devices 4 are respectively arranged at the left side and the right side of the furnace body 1, and the blocking devices 4 comprise a driving mechanism 41, a lifting plate 42 and a baffle 43. The driving device comprises a motor 413, two groups of driving wheels 411, driven wheels 412 and a belt 414. The driving pulley 411 and the driven pulley 412 are driven by a belt 414. A connecting shaft 415 is respectively arranged between the two driving wheels 411 and the two driven wheels 412 which are positioned on the same side in a penetrating manner, and the connecting shaft 415 enables the two corresponding driving wheels 411 and the two corresponding driven wheels 412 to rotate simultaneously. Two ends of the connecting shaft 415 connected with the driving wheel 411 are respectively provided with a rotating bearing, the connecting shaft 415 is fixedly connected with an inner ring of the rotating bearing, a bearing seat is fixedly connected inside the furnace body 1, and an outer ring of the rotating bearing is fixedly connected with the bearing seat. The connecting shaft 415 connected with the driving wheel 411 is fixedly connected with the motor 413 through a coupler. Both ends of a connecting shaft 415 connected to the driven pulley 412 are rotatably connected to the inner wall of the furnace body 1, respectively. The belt 414 is fixedly connected to the lower end of the lifting plate 42. The motor 413 drives the driving wheel 411 to rotate, thereby driving the lifting plate 42 to move upwards.

The upper end of the lifting plate 42 is hinged with the baffle 43, and the hinged position is arranged on one side of the lifting plate 42 far away from the inner side of the furnace body 1. When the elevating plate 42 is raised, the baffle 43 is pushed to rise, and when the elevating plate 42 is raised until the baffle 43 is completely exposed out of the furnace body 1, the baffle 43 can rotate to the inner side or the outer side of the furnace body 1 due to the action of gravity. When two baffles 43 rotated to the inboard of furnace body 1, two baffles 43 carried out the closing cap to stove dish 2, avoided the staff to touch stove dish 2 by mistake and cause the scald when stove dish 2 still is in high temperature state.

The thickness of baffle 43 is less than the thickness of lifter plate 42, and baffle 43 and lifter plate 42 keep away from the inboard one side of furnace body 1 articulated, and the lifter plate 42 keeps away from the inboard one side of furnace body 1 and upwards extends limiting plate 421, and limiting plate 421 sets up in the inboard one side of keeping away from furnace body 1 in articulated position. When the baffle 43 is completely exposed out of the furnace body 1, the limit plate 421 limits the baffle 43 to prevent the baffle 43 from rotating to the outside of the furnace body 1. When the baffle 43 rotates to be parallel to the upper surface of the furnace body 1 toward the inner side of the furnace body 1, since the hinge joint between the baffle 43 and the lifting plate 42 is provided at the side of the lifting plate 42 away from the inner side of the furnace body 1, the baffle 43 abuts against the upper surface of the lifting plate 42, and the baffle 43 is restricted from further rotation.

The furnace body 1 is provided with a second vent hole 13, the second vent hole 13 penetrates through the left side wall and the right side wall of the furnace body 1, and the lifting plate 42 is provided with a first vent hole 422 corresponding to the second vent hole 13. When the furnace plate 2 is accommodated in the plate groove 11, the air temperature in the accommodating groove is high, and the high-temperature air in the accommodating groove can flow out from the first ventilation hole 422 and the second ventilation hole 13 by arranging the first ventilation hole 422 and the second ventilation hole 13, so that the furnace plate 2 can be cooled quickly.

The implementation principle of the embodiment is as follows: when the universal resistance furnace is in a normal use state, the switch 12 is in an open state, the baffle 43 and the lifting plate 42 are accommodated in the furnace body 1, the furnace plate 2 is higher than the upper surface of the furnace body 1, an object to be heated is placed on the furnace plate 2, the heating wires 22 placed in the furnace plate 2 are electrified, and the object to be heated is heated. When the universal resistance furnace is used, an operator removes the heated object from the furnace plate 2, then the operator switches the switch 12 from the open state to the off state, at the moment, the electric heating wire 22 stops being electrified, the electric push rod 3 drives the furnace plate 2 to descend, meanwhile, the motor 413 drives the driving wheel 411 to rotate, so as to drive the belt 414 to move, so that the lifting plate 42 and the baffle 43 move upwards, when the baffle 43 is completely exposed out of the furnace body 1, the baffle 43 turns over towards the direction close to the inner side of the furnace plate 2 due to the action of gravity, the baffle 43 on the two sides covers the furnace plate 2, and the furnace plate 2 in the furnace body 1 is cooled gradually.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
