[0029] 1. In the utility model, in order to solve the problem that when the trolley furnace in the related technology is used, there will be a certain gap between the trolley and the furnace body, and the high-temperature gas will leak from the gap, causing the high temperature of the external environment, when the trolley furnace door is closed, the telescopic part contracts, driving the swing rod to move, and the swing rod moves upward in an arc under the support of the connecting rod.

[0041] Example 1
[0042] Reference Figure 1~Figure 4 , which is the first embodiment of the utility model, proposes a furnace body sealing device for sealing the gap 1 at the lower end of the trolley furnace, including a bottom plate 2; a telescopic member 3 is fixedly arranged on the bottom plate 2; one end of a rocker arm 4 is rotatably arranged on the telescopic member 3; one end of a connecting rod 5 is rotatably arranged on the rocker arm 4, and the other end of the connecting rod 5 is rotatably arranged on the bottom plate 2; a sealing member 6 is fixedly arranged on the rocker arm 4, and the sealing member 6 is used to abut against the gap 1.
[0043] In this embodiment, in order to solve the problem that when the trolley furnace in the related technology is used, there will be a certain gap between the trolley and the furnace body, and the high-temperature gas will leak from the gap, causing the high temperature of the external environment. After the workpiece of the trolley furnace is placed and the furnace door is closed, the telescopic part 3 contracts, driving the swing rod 4 to move, and the swing rod 4 moves upward in an arc under the support of the connecting rod 5. The seal 6 is fixed on the swing rod 4 and always abuts against the gap at the lower end of the trolley furnace. When the swing rod 4 moves upward, the seal 6 will tightly abut against the gap at the lower end of the trolley furnace, thereby achieving a sealing effect. It can greatly reduce the leakage of high-temperature gas, which can not only reduce the temperature around the trolley furnace when it is working, but also reduce energy consumption.
[0044] Specifically, when the door of the trolley furnace is closed, the telescopic member 3 contracts, and the telescopic member 3 drives the swing rod 4 to move. Since the swing rod 4 is connected to the bottom plate 2 through the connecting rod 5, when the telescopic member 3 contracts, the swing rod 4 will move upward in an arc. The sealing member 6 is fixed on the swing rod 4 and always abuts against the gap at the lower end of the trolley furnace. When the swing rod 4 moves upward, the sealing member 6 will closely abut against the gap at the lower end of the trolley furnace. When the telescopic member 3 drives the swing rod 4 to move to the point where the connecting rod 5 is perpendicular to the bottom plate 2, it stops. At this time, the connecting rod 5 can withstand the maximum vertical force, which helps the sealing member 6 to closely abut against the gap at the lower end of the trolley furnace to achieve a sealing effect. It can greatly reduce the leakage of high-temperature gas, which can not only reduce the temperature around the trolley furnace when it is working, but also reduce energy consumption.
[0045] Furthermore, the sealing member 6 includes a fastener 7 , which is disposed on the upper surface of the rocker arm 4 ; and a sealing strip 8 is disposed inside the fastener 7 .
[0046] In this embodiment, the sealing member 6 includes a fastener 7 and a sealing strip 8. The fastener 7 is fixed on the rocker arm 4, and the sealing strip 8 is arranged in the fastener 7. When the sealing strip 8 is old and needs to be replaced, the sealing strip 8 can be taken out of the fastener 7 and replaced with a new one.
[0047] Furthermore, the lower surface of the rocker arm 4 has a first groove 401, and the number of the first grooves 401 is several. It also includes a horizontal sliding rod 9, and the number of the horizontal sliding rods 9 is several, and the horizontal sliding rods 9 are arranged in the first groove 401; the number of lifting members 10 is several, and the lifting members 10 are fixedly set on the base plate 2, and the rocker arm 4 is relatively slidably set on the lifting members 10.
[0048] In this embodiment, the lower surface of the rocker arm 4 has a groove, and a horizontal sliding rod 9 is installed inside the groove. The horizontal sliding rod 9 is connected to the lifting member 10. When the rocker arm 4 moves upward, the horizontal sliding rod 9 will drive the lifting member 10 to move upward. The function of the lifting member 10 is to ensure that the movement trajectory of the rocker arm 4 is upward, and it can also extend the life of the furnace body sealing device.
[0049] Furthermore, the horizontal sliding rod 9 has a first protrusion 901 and a second groove 902 at both ends respectively, the first protrusion 901 is used to insert the rocker arm 4, and also includes a toggle plate 11, one end of the toggle plate 11 has a second protrusion 1101, the second protrusion 1101 is used to insert the rocker arm 4, and the toggle plate 11 is slidably set in the second groove 902; the cover 12 is fixedly set at the end of the second groove 902 to prevent the toggle plate 11 from falling off; the elastic member 13 is set in the second groove 902 to provide elastic force for the toggle plate 11 to approach the cover 12.
[0050] In this embodiment, the two ends of the horizontal sliding rod 9 have a second groove 902 and a first protrusion 901, respectively. The first protrusion 901 is used to insert into the first groove 401 to fix the horizontal sliding rod 9, and the second groove 902 is used to place the toggle piece 11 and the elastic member 13. After the toggle piece 11 and the elastic member 13 are placed, the cover 12 is installed at the outermost side of the second groove 902. The function of the cover 12 is to prevent the toggle piece 11 from falling off. When installing the horizontal sliding rod 9, first press the toggle piece 11, insert the first protrusion 901 of the horizontal sliding rod 9 into the swing rod 4, release the toggle piece 11 after the position is corrected, and under the elastic force of the elastic member 13, the toggle piece 11 is reset, and the second protrusion 1101 on the toggle piece 11 is inserted into the swing rod 4, completing the installation of the horizontal sliding rod 9.
[0051] Furthermore, the lifting member 10 includes: a vertical guide shaft 14 , one end of which is fixedly disposed on the bottom plate 2 ; a guide block 15 slidably disposed on the vertical guide shaft 14 , and a horizontal sliding rod 9 slidably disposed on the other end of the guide block 15 .

The vertical guide shaft 14 is fixedly arranged on the bottom plate 2, and the guide block 15 slides vertically on the vertical guide shaft 14. When the swing rod 4 moves upward in an arc, the horizontal sliding rod 9 slides horizontally on the guide block 15, and the horizontal sliding rod 9 drives the guide block 15 to move upward along the vertical guide shaft 14. The function of the lifting member 10 is to ensure that the upward movement trajectory of the swing rod 4 is consistent, and at the same time, to extend the service life of the furnace body sealing device.
[0053] Furthermore, there are sliding grooves 903 on both sides of the horizontal sliding rod 9, and the sliding grooves 903 are located at one end of the horizontal sliding rod 9 close to the second groove 902. The second groove 902 is connected to the sliding groove 903, and also includes a toggle handle 16, which is fixedly arranged on both sides of the toggle plate 11, and the toggle handle 16 extends out of the sliding groove 903.
[0054] In this embodiment, the horizontal sliding rod 9 has a slide groove 903 near the second groove 902, and the slide groove 903 is connected to the second groove 902. Both sides of the toggle plate 11 are provided with a toggle handle 16, which slides horizontally in the slide groove 903 to facilitate the operator to press the toggle plate 11.
[0055] Furthermore, the first protrusion 901 and the second groove 902 are both circular, which facilitates the installation and sliding of the horizontal sliding rod 9.
[0056] In this embodiment, the first protrusion 901 and the second groove 902 on the horizontal sliding rod 9 are both circular, which is convenient for installing the horizontal sliding rod 9 .
