[0045] like Figures 2 to 4 As shown, a through groove 302 is provided on the outer wall of the connecting block 301, a rotating rod 303 is rotatably connected to the inner wall of the connecting block 301, a gear 1 304 is fixedly connected to the outer wall of the bottom end of the rotating rod 303, a threaded ring 305 is threadedly connected to the outer wall of the rotating rod 303, a gear 2 307 is meshed with the outer wall of the gear 1 304, a rotating block 306 is fixedly connected to the outer wall of the gear 2 307, a threaded block 309 is hinged to the outer wall of the rotating block 306 through a connecting rod 308, and a slider 310 is fixedly connected to the outer wall of the threaded block 309.

[0046] The above scheme is adopted: multiple groups of through grooves 302 are provided, each group of through grooves 302 corresponds to a group of threaded blocks 309, and threaded holes are provided on the threaded blocks 309, and the threaded holes correspond to the positions of the through grooves 302; the rotating rod 303 can rotate outside the connecting block 301, and its outer wall is provided with external threads, which are threadedly connected with the threaded ring 305. When the threaded ring 305 is rotated, the rotating rod 303 can be fixed, and the fixing of the rotating rod 303 can also be released to rotate it alone; when the rotating rod 303 rotates, it will drive the gear 1 304 to rotate synchronously. Since the gear 1 304 is meshed with the gear 2 307, it can drive the gear 2 307 to rotate synchronously.

[0047] like Figures 2 to 4As shown, the connecting pipe 4 is fixedly connected to the outer wall of the furnace body 1, the connecting block 301 is fixedly connected to the outer wall of the connecting pipe 4, the gear 1 304 and the gear 2 307 are both rotatably connected to the inner wall of the connecting block 301, and the rotating rod 303 passes through the top outer wall of the connecting block 301; one end of the connecting rod 308 is hinged to the outer wall of the rotating block 306, and the other end of the connecting rod 308 is hinged to the outer wall of the threaded block 309, and the slider 310 is slidably connected to the inner wall of the connecting block 301.

[0048] The above scheme is adopted: when the threaded ring 305 is rotated to make it disengage from the connecting block 301, the limit of the rotating rod 303 can be released to rotate it; when the gear 2 307 rotates, the rotating block 306 rotates synchronously, driving one end of the connecting rod 308 hinged on its outer wall to move along the circumference, and the other end of the connecting rod 308 is hinged to the threaded block 309, and the threaded block 309 and the slider 310 are both slidably connected to the inner wall of the connecting block 301 and can only move in a straight line, so that the rotating block 306 can be rotated to drive multiple groups of threaded blocks 309 to move toward the center or The threaded hole on the threaded block 309 is always connected with the through groove 302, so that the position of the threaded block 309 can be adjusted to make the threaded hole correspond to the position of the threaded hole of the external pipeline flange of the vacuum pump 2, and the fixing bolt can be inserted into the threaded hole, and the pipeline connection is completed by the nut. No matter where the threaded hole of the external pipeline flange of the vacuum pump 2 is, the position of the threaded block 309 can be adjusted to complete the installation, avoiding the problem that the connecting pipe 4 cannot be connected and used due to the mismatch between the threaded hole of the external pipeline of the vacuum pump 2.

[0049] like Figures 5 to 7 As shown, the outer wall of the bottom end of the clamping block 602 is hinged with a moving block 604 through a hinge rod 603, the inner wall of the moving block 604 is elastically connected with an insert block 606 through a connecting spring 605, and a slot 607 is opened on the outer wall of the bottom end of the placement plate 601.

[0050] The above scheme is adopted: two groups of clamping blocks 602 and hinged rods 603 are provided, which are symmetrically distributed on both sides of the placement plate 601, and the clamping blocks 602 can move horizontally on the surface of the placement plate 601; the moving block 604 passes through the outer wall of the bottom end of the placement plate 601, and the operator can pull or push the moving block 604 from the bottom of the placement plate 601 to adjust the position of the clamping block 602; a container equipped with bolts can be placed on the placement plate 601, and when the positions of the clamping blocks 602 on both sides are adjusted to make them contact with both sides of the container, the container can be clamped and fixed, ensuring that the container will not move due to the vibration of the furnace body 1 during operation, thereby ensuring the effect of heat treatment.

[0051] like Figures 5 to 7As shown, the placement plate 601 is fixedly connected to the inner wall of the furnace body 1, one end of the hinged rod 603 is hinged to the outer wall of the moving block 604, the other end of the hinged rod 603 is hinged to the outer wall of the clamping block 602, the moving block 604 passes through the bottom outer wall of the placement plate 601, and the moving block 604 is slidably connected to the inner wall of the placement plate 601; one end of the connecting spring 605 is fixedly connected to the inner wall of the moving block 604, the other end of the connecting spring 605 is fixedly connected to the outer wall of the plug block 606, the plug block 606 is slidably connected to the inner wall of the moving block 604, and the plug block 606 is snap-fitted into the slot 607.

[0052] The above scheme is adopted: when the moving block 604 moves, it will drive the two sets of hinged rods 603 to move synchronously, and the hinged rods 603 will pull the two sets of clamping blocks 602 to move, and the hinged rods 603 will flip; under normal conditions, the connecting spring 605, due to its own elastic force, keeps the plug block 606 always popped out and engaged with a set of slots 607, fixing the moving block 604, so that the position of the clamping block 602 is fixed, and when the plug block 606 is pulled, the connecting spring 605 will be forced to shrink, and the plug block 606 06 is out of contact with the slot 607, the limit of the moving block 604 can be released to move it; when the moving block 604 moves to a suitable position and the clamping block 602 fits with both sides of the container, the plugging block 606 can be loosened, and under the elastic force of the connecting spring 605, the plugging block 606 will rebound and reset, and engage with the corresponding slot 607 to complete the fixing operation; there are multiple groups of slots 607, which can fix the moving block 604 and the clamping block 602 in multiple positions, improve adaptability, and the overall operation is also more convenient.

[0053] like Figure 5 and Figure 8 As shown, the inner wall of the fixed block 701 is elastically connected to the trapezoidal block 704 through the telescopic spring 702, the outer wall of the trapezoidal block 704 is fixedly connected to the moving rod 703, the inner wall of the fixed block 701 is slidably connected to the short rod 705, and the outer wall of the nozzle 8 is provided with a slot 707.

[0054] The above scheme is adopted: there are four groups of trapezoidal blocks 704, which are distributed in pairs on the inner walls of both sides of the fixed block 701, with two groups of trapezoidal blocks 704 on each side, and the two groups of trapezoidal blocks 704 on the same side are fixed by a group of moving rods 703; the outer wall of the moving rod 703 is provided with a protrusion, the protrusion passes through the side wall of the fixed block 701, and the moving rod 703 can be driven to move synchronously by moving the protrusion, and the two groups of trapezoidal blocks 704 fixed thereto can be moved synchronously; the coolant tank 5 is connected to the nozzle 8 through the installation mechanism 7, and the coolant therein will be sprayed out through the nozzle 8 to the bolt for cooling, and the nozzle 8 can be conveniently and quickly disassembled and installed through the installation mechanism 7 for cleaning or replacement.

[0055] like Figure 5 and Figure 8As shown, the fixed block 701 is fixedly connected to the outer wall of the bottom end of the coolant tank 5, the nozzle 8 is clamped in the inner wall of the fixed block 701, one end of the short rod 705 is slidably connected to the outer wall of the trapezoidal block 704, and the other end of the short rod 705 is fixedly connected to the outer wall of the clamping block 706; one end of the telescopic spring 702 is fixedly connected to the outer wall of the trapezoidal block 704, and the other end of the telescopic spring 702 is fixedly connected to the inner wall of the fixed block 701, the trapezoidal block 704 and the moving rod 703 are both slidably connected to the inner wall of the fixed block 701, and the clamping block 706 is clamped in the clamping groove 707.

[0056] The above scheme is adopted: under normal conditions, the telescopic spring 702 drives the trapezoidal block 704 and the moving rod 703 to a certain position. At this time, the long side inclined surface of the trapezoidal block 704 contacts the short rod 705, so that the short rod 705 drives the clamping block 706 to be pushed outward and clamped in the clamping groove 707, so that the nozzle 8 can be fixed; when the convex block is moved to drive the moving rod 703 and the trapezoidal block 704 to move, the short rod 705 will move along its inclined surface. Since the short rod 705 can only be moved in the fixed block 7 01, so that the short rod 705 can drive the card block 706 to move into the inner wall of the fixed block 701 and break away from the card slot 707, and the nozzle 8 can be removed; when the nozzle 8 needs to be installed, the protrusion can also be moved to move the card block 706 to the inner wall of the fixed block 701, and the nozzle 8 can be inserted into the fixed block 701, and the trapezoidal block 704 can be reset by the telescopic spring 702, so that the card block 706 is reset and inserted into the card slot 707 to complete the installation.

[0057] The working principle and use process of the present invention:

[0058] When it is necessary to connect vacuum pumps 2 of different specifications to the furnace body 1, the connection mechanism 3 can be adjusted according to the position of the threaded hole of the external pipeline of the vacuum pump 2; the threaded ring 305 is rotated to make it disengage from the connection block 301, the limit of the rotating rod 303 is released, and the rotating rod 303 is rotated to drive the gear 1 304, the gear 2 307 and the rotating block 306 to rotate synchronously, and the connecting rod 308 hinged on the outer wall drives the multiple groups of threaded blocks 309 to move toward the center or the circumference at the same time. When the threaded hole on the threaded block 309 corresponds to the position of the threaded hole of the external pipeline flange of the vacuum pump 2, the fixing bolt is inserted into the threaded hole, and the pipeline connection is completed by the nut; therefore, no matter where the threaded hole of the external pipeline of the vacuum pump 2 is, the position of the threaded block 309 can be adjusted by the connection mechanism 3 for installation and fixing, which has higher adaptability and avoids the problem that the external pipeline of the vacuum pump 2 and the connecting pipe 4 cannot be connected due to the mismatch of the threaded hole positions.

[0059] After the vacuum pump 2 is connected to the furnace body 1, the door panel of the front section of the furnace body 1 can be opened, and the container with bolts can be placed on the placement plate 601 on the inner wall of the furnace body 1. The plug block 606 is pulled to move the moving block 604 forward and backward from under the placement plate 601. The moving block 604 pulls the two groups of clamping blocks 602 to move horizontally on the surface of the placement plate 601 through two groups of hinged rods 603; when the clamping block 602 contacts both sides of the container, the connecting spring 605 causes the plug block 606 to pop out and engage with a group of slots 607 to fix the moving block 604, thereby fixing the position of the clamping block 602, and completing the clamping and fixation of the container with bolts.

[0060] Then close the door panel and start the vacuum pump 2 to evacuate the furnace body 1. The furnace body 1 uses heating elements with high electrothermal conversion efficiency such as molybdenum wire and tungsten wire to heat treat the bolts at a higher temperature under a vacuum environment. After the vacuum pump 2 quickly evacuates the furnace body 1 to the required vacuum degree, the operating time is reduced and the energy consumption is reduced.

[0061] After the heat treatment is completed, the coolant in the coolant tank 5 is sprayed onto the bolts through the nozzle 8 to quickly cool the bolts; after the bolts are cooled, the door panel is opened, the moving block 604 is moved to drive the clamping block 602 away from the container, and the container containing the bolts is taken out to complete the heat treatment.

[0062] When the nozzle 8 needs to be cleaned or replaced, the outer wall protrusion of the movable rod 703 is pushed to drive the movable rod 703 and the trapezoidal block 704 to move, and the clamping block 706 is driven by the short rod 705 to move to the inner wall of the fixed block 701 to break away from the outer wall clamping groove 707 of the nozzle 8, so that the nozzle 8 can be removed from the fixed block 701 for cleaning or replacement.

[0063] When installing the nozzle 8, the protrusion is also moved to move the clamping block 706 to the inner wall of the fixed block 701, and the nozzle 8 is inserted into the fixed block 701 so that the clamping slot 707 corresponds to the position of the clamping block 706. The installation of the nozzle 8 can be completed by clamping the clamping block 706 and the clamping slot 707. There is no need to install or disassemble the nozzle 8 by turning the bolt, which is convenient and quick.
