[0004] the purpose of the utility model is to provide a smoke side suction gas collecting cover in the furnace, which has the advantage of convenient connection of the gas collecting cover, and solves the problem that the existing gas collecting cover is not convenient for users to connect.
[0005] in order to achieve the above purpose, the utility model provides the following technical scheme: a Fume Extractor Arm, which includes a heating furnace, the top of the left side of the heating furnace is connected with an interface, the top and bottom of the left side of the interface are provided with positioning slots, the left side of the heating furnace and the top and bottom of the interface are fixedly connected with a shell, and the inner side of the inner wall of the shell is fixedly connected with a bearing, The inner part of the bearing is fixedly connected with a screw, the surface of the screw is threaded with a screw sleeve, the right side of the screw sleeve is fixedly connected with a lifting plate, the inner side of the lifting plate is fixedly connected with a spring, the end of the spring away from the lifting plate is fixedly connected with the inner wall of the shell, the left side of the screw sleeve is fixedly connected with a connecting rod, and the left end of the connecting rod penetrates to the outside of the shell and is fixedly connected with a vertical plate, The front of the vertical plate is fixedly connected with a transmission rod, the left side of the interface is provided with a gas collecting cover, the top and bottom of the gas collecting cover are fixedly connected with a trapezoidal block used in conjunction with the transmission rod, the right side of the trapezoidal block is fixedly connected with a positioning rod, and the right end of the positioning rod extends to the interior of the positioning groove.
[0006] preferably, both sides of the bottom of the heating furnace are fixedly connected with cushion blocks, and the bottom
[0007] preferably, the end of the screw away from the bearing penetrates to the outside of the shell and is fixedly connected with a rotary table, which is used in conjunction with the screw.
[0008] preferably, the right side of the lifting plate is fixedly connected with a slider, the right side of the inner wall of the shell is provided with a chute, and the slider is slidably connected with the chute.
[0009] preferably, the right side of the gas collecting cover is fixedly connected with a sealing ring, and the right side of the sealing ring is in contact with the left side of the interface.
[0010] preferably, the vertical plate is located at the rear side of the trapezoidal block, and the surface of the transmission rod is in contact with the left side of the trapezoidal block. [0011] compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] 1. By setting a heating furnace, an interface, a positioning groove, a shell, a bearing, a screw, a screw sleeve, a lifting plate, a spring, a connecting rod, a vertical plate, a transmission rod, a gas collecting cover, a trapezoidal block and a positioning rod, the utility model solves the problem that the existing gas collecting cover is not convenient for users to connect. The smoke side suction gas collecting cover in the furnace has the advantage of convenient connection of the gas collecting cover and saves users a lot of time, The utility of the heating furnace is improved.
[0013] 2. By setting the cushion block, the utility model can increase the friction between the bottom of the heating furnace and the ground to prevent the abnormal movement of the heating furnace. By setting the rotary table, the contact area between the user's hand and the screw can be increased, which is convenient for the user to rotate the screw through the rotary table. By setting the sliding block and chute, the stability of the lifting plate can be increased, and the tilting of the lifting plate can be prevented. By setting the sealing ring, It can increase the tightness of the gas hood and the interface, and prevent smoke from leaking between the gas hood and the interface.
