[0002] A vacuum furnace is a device that heats in a vacuum environment. A vacuum furnace is generally composed of a main machine, a furnace, an electric heating device, a sealed furnace shell, a vacuum system, a power supply system, a temperature control system, and a transport vehicle outside the furnace. The sealed furnace shell is welded with carbon steel or stainless steel, and the joint surfaces of the removable parts are sealed with vacuum sealing materials. In order to prevent the furnace shell from deforming after heating and the sealing material from deteriorating after heating, the furnace shell is generally cooled by water or air. The furnace is located inside the sealed furnace shell. Depending on the purpose of the furnace, different types of heating elements are installed inside the furnace. The vacuum system is mainly composed of a vacuum pump, a vacuum valve, and a vacuum gauge.

[0051] In one aspect of the present embodiment, a second arc-shaped groove 81 for the other end of the heating belt 6 to pass through is provided at the bottom of the movable clamping seat 8, and a fixing clamp 13 for fixing the other end of the heating belt 6 is provided through the second arc-shaped groove 81, and the fixing clamp 13 includes a second positioning block 131, and the second positioning block 131 is vertically slidably connected to the movable clamping seat 8, and a second connecting rod 132 is fixedly connected to the top of the second positioning block 131, and a second connecting block 133 is fixedly connected to the top of the second connecting rod 132, and a sliding groove 83 is provided on the top wall of the second arc-shaped groove 81 for sliding connection with the second positioning block 131, and a positioning hole 61 is also provided on the other end of the heating belt 6 for use with the second positioning block 131. After one end of the heating belt 6 is positioned by the first positioning block 121, the other end of the heating belt 6 is pulled to bypass the annular groove 51 and extend into the second arc groove 81. Similarly, the second connecting block 133 is lifted upward with the other hand, and the second positioning block 131 is driven to move upward in the slide groove 83 by the second connecting rod 132 so that one end of the heating belt 6 can pass through; the movement limit of the slide groove 83 can prevent the second positioning block 131 from being directly brought out; when the positioning hole 61 at the other end of the heating belt 6 moves to the bottom of the second positioning block 131, the second connecting block 133 is pressed downward again, and the second positioning block 131 is driven to move downward by the second connecting rod 132 and pass through the positioning hole 61, so that the other end of the heating belt 6 is sleeved on the second positioning block 131 to position the other end of the heating belt 6; when connecting the other end of the heating belt 6, the position of the movable holder 8 can be adjusted according to the length of the heating belt 6 to adapt to heating belts 6 of different lengths and improve the flexibility of use.

[0052] In one aspect of the present embodiment, the connecting member includes an arc-shaped block 11, a mounting groove 82 is provided at the top of the movable base 8 near the side edge of the fixed base 7, the interior of the mounting groove 82 is rotatably connected to the rotating rod 10, and one end of the arc-shaped block 11 is fixedly sleeved on the outer wall of the rotating rod 10, a plurality of latch teeth 112 are provided at the bottom of the arc-shaped block 11, an arc-shaped slot 73 for use with the arc-shaped block 11 is provided at the top of the fixed base 7, and the through hole 732 is located in the arc-shaped slot 73, a plurality of tooth grooves 731 for meshing with the latch teeth 112 are provided on the bottom wall of the arc-shaped slot 73, a yielding slot 111 for use with the first connecting rod 122 is provided at the top of the arc-shaped block 11, a limiting slot 113 for use with the first positioning block 121 is provided at the bottom of the arc-shaped block 11, and the limiting slot 113 is communicated with the yielding slot 111. First, adjust the position of the movable clamping seat 8 according to the different lengths of the heating belt 6. During the adjustment process, rotate the arc-shaped clamping block 11 upward to disengage the clamping teeth 112 from the meshing with the tooth groove 731. After the adjustment is completed and both ends of the heating belt 6 are positioned, the movable clamping seat 8 can be moved and adjusted again to move the movable clamping seat 8 toward the fixed clamping seat 7, and the heating belt 6 can be stretched so that the heating belt 6 can be tightly attached to the annular groove 51. During the adjustment process, rotate the arc-shaped clamping block 11 upward as well. After the adjustment is completed, rotate and lower the arc-shaped clamping block 11 and clamp it in the arc-shaped clamping groove 73. At this time, the clamping teeth 112 can be meshed and positioned with the tooth groove 731, thereby completing the positioning between the fixed clamping seat 7 and the movable clamping seat 8. The connection makes the heating belt 6 in a certain tensioned and fitted state; by setting the giving way notch 111, the arc-shaped clamping block 11 can move with the movable clamping seat 8 without being hindered by the first connecting rod 122, and it is also convenient for the arc-shaped clamping block 11 to rotate a certain angle; by setting the limiting groove 113, when the first positioning block 121 is driven to move upward by the first connecting rod 122, the top of the first positioning block 121 can pass through the through hole 732 and enter the limiting groove 113, so that the first positioning block 121 can move up a greater stroke, so that one end of the heating belt 6 can pass normally, and the upward movement of the first positioning block 121 can also be limited by the limiting groove 113 to avoid the first positioning block 121 being directly brought upward.

[0053] In one aspect of this embodiment, two arc-shaped slide bars 9 are symmetrically fixedly connected to one side of the movable card seat 8 close to the fixed card seat 7, and two arc-shaped slide holes 72 are symmetrically opened on one side of the fixed card seat 7 to be slidably connected to the corresponding arc-shaped slide bars 9. By sliding the arc-shaped slide bars 9 in the arc-shaped slide holes 72, the stability of the operation can be improved when the movable card seat 8 is adjusted.

[0054] In one aspect of the present embodiment, the bottom wall of the annular groove 51 is provided with an engaging groove 511 for use with the first positioning block 121 and the second positioning block 131. Through the provision of the engaging groove 511, the bottoms of the first positioning block 121 and the second positioning block 131 can be embedded in the engaging groove 511, so that the two ends of the heating belt 6 can be better sleeved on the first positioning block 121 and the second positioning block 131, thereby improving the stability of the connection of the heating belt 6; at the same time, when the position of the second positioning block 131 changes with the adjustment of the movable clamping seat 8, it can always move along the engaging groove 511, thereby facilitating the stable pulling of one end of the heating belt 6, and preventing the heating belt 6 from falling off during the force application process.

[0055] Example 2

[0056] This embodiment is a further improvement of the previous embodiment: Figure 1 - Fig.16As shown, the hanging device also includes a plurality of groups of reinforcing members 14 for reinforcing the positioning of the corresponding movable sockets 8, the reinforcing members 14 include two sliders 141 symmetrically slidably connected to the outer wall of the mounting tube 5, a same arc-shaped connecting strip 142 that fits the outer wall of the mounting tube 5 is fixedly connected between the two sliders 141, an arc-shaped opening 1421 is provided on one side of the arc-shaped connecting strip 142, the first connecting block 123 is rotatably connected to the first rotating shaft 124 at one end away from the first connecting rod 122, the first rotating shaft 124 is fixedly connected to the first stop block 125 at one end away from the first connecting block 123, the second connecting block 133 is rotatably connected to the second rotating shaft 134 at one end away from the second connecting rod 132, and the second rotating shaft 134 is fixedly connected to the second stop block 135 at one end away from the second connecting block 133. After adjusting the movable base 8 to tighten the heating belt 6, the arc-shaped block 11 is engaged in the arc-shaped groove 73, and the engagement between the locking teeth 112 and the tooth groove 731 is used to complete the fixed connection between the movable base 8 and the fixed base 7, and then the two sliders 141 are pushed by both hands to drive the arc-shaped connecting strip 142 to move. Since the position of the fixed base 7 is in a fixed state, one of the sliders 141 can directly slide and fit on the top of the fixed base 7, and the position of the movable base 8 will change with the length of the heating belt 6, so the other slider 141 may slide and fit on the top of the movable base 8, or may not have contact with the movable base 8, but the arc-shaped connecting strip 142 will make the first stop block 125, the first rotating shaft 124, the second stop block 135 and the second rotating shaft 134 pass through the arc opening as the slider 141 moves. 1421, and then it will conflict with one side of the first connecting block 123 and the second connecting block 133 and cannot move further. At this time, the first block 125 and the second block 135 just pass outward, and at the same time, the bottom of the arc-shaped connecting strip 142 will fit and conflict with one side of the top of the arc-shaped clamping block 11. Through the conflict with the arc-shaped clamping block 11, the rotation of the arc-shaped clamping block 11 can be limited, and then the movement of the movable clamping seat 8 can be limited, thereby completing the reinforced positioning of the movable clamping seat 8 and ensuring the stability of the heating belt 6 during use. Finally, the first block 125 and the second block 135 are rotated vertically so that they conflict with one side of the arc-shaped connecting strip 142, and the positioning of the entire reinforcement 14 can be completed; the whole process does not require the use of screws for connection, the operation is also very simple, and it can also have a good tightening effect on the heating belt 6, and it can also be suitable for heating belts 6 of different lengths.

[0057] Example 3

[0058] This embodiment is a further improvement of the previous embodiment: Figure 1 - Fig.14As shown, a mounting notch 1211 is provided on one side of the first positioning block 121 close to the movable holder 8, a movable block 126 is slidably connected inside the mounting notch 1211, and at least one spring 127 is fixedly connected between one side of the movable block 126 and the inner wall of one side of the mounting notch 1211. Since the two ends of the heating belt 6 are respectively sleeved on the first positioning block 121 and the second positioning block 131, the force on one end of the heating belt 6 sleeved on the first positioning block 121 will act on the movable block 126, and when the other end of the heating belt 6 is adjusted and tightened by the movable holder 8, the movable block 126 will be driven to move, so that the spring 127 is subjected to a certain extrusion force, so that the spring 127 is in a compressed state. During use, through the deformation of the spring 127, an effective deformation space can be provided according to the thermal expansion and contraction of the heating belt 6, so as to prevent the heating belt 6 from being deformed and cracked, thereby effectively improving the service life of the heating belt 6.

[0059] Example 4

[0060] This embodiment is a further improvement of the previous embodiment: Figure 1 - Fig.17 As shown, the hanging device also includes a clamping member 15 for clamping one end of the heating belt 6. The clamping member 15 includes an adjusting screw 152 that is threadedly connected to the bottom wall of the arc-shaped slot 73. The bottom end of the adjusting screw 152 extends into the first arc-shaped slot 71 and is rotatably connected to a pressure block 151. The top end of the adjusting screw 152 passes upward through the yielding slot 111 and is fixedly connected to a rotating handle 153. When one end of the heating belt 6 passes through the first arc groove 71 and is positioned and connected by the first positioning block 121, one end of the heating belt 6 will extend to the bottom of the pressing block 151. At this time, the turning handle 153 can be rotated to drive the adjusting screw 152 to rotate, and drive the pressing block 151 to move downward and press on one end of the heating belt 6. As the adjusting screw 152 rotates, one end of the heating belt 6 can be pressed; then the other end of the heating belt 6 is positioned and connected by the second positioning block 131, and then the heating belt 6 is tightened by the movement and adjustment of the movable holder 8. Since the other end of the heating belt 6 is pressed by the pressing block 151, it will not drive the movable block 126 to move; when After the heating belt 6 is tightened and the movable holder 8 is fixed, the handle 153 is rotated to drive the adjusting screw 152 to reverse, so that the pressure block 151 moves upward and the pressure on one end of the heating belt 6 is released. Since the heating belt 6 was in a tensioned state before, after the pressure is released, it will drive the movable block 126 to move adaptively under the action of its own tension, which not only enables the heating belt 6 to fit in the annular groove 51 to ensure the heating effect, but also avoids excessive tensioning of the heating belt 6 and affecting the normal use of the heating belt 6. At the same time, through the elastic force of the spring 127, the heating belt 6 has a certain thermal expansion and contraction space, and can better adapt to the deformation space.

[0061] In one aspect of this embodiment, a rubber pad 154 is provided at the bottom of the pressing block 151. Since the heating belt 6 is installed in an annular shape and fits in the annular groove 51, the provision of the rubber pad 154 can, on the one hand, provide a protective effect on the pressing of the heating belt 6, and on the other hand, can better adapt to the arc surface pressing, so that the pressing effect of the heating belt 6 is better and more stable.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
