It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification. Embodiment 1

[0024] Please refer to Figures 1-5The utility model provides a technical solution: a vacuum heat treatment furnace that is easy to load and unload, including a base 1, a shell 2 is installed on the top of the base 1, a support block 3 is installed inside the shell 2, a heating ring 4 is installed on the inner wall of the support block 3, a side block A5 is installed on the left side of the shell 2, a side block B7 is arranged on the surface of the side block A5, a cover plate 8 is installed on the right side of the side block B7, a handle 9 is installed on the surface of the cover plate 8, a support rod 10 is installed inside the shell 2, a fixing plate 11 is installed on the top of the support rod 10, a limiting plate 12 is installed on the top of the fixing plate 11, a limiting block 14 is arranged inside the limiting plate 12, and the limiting block 14 A sliding plate 15 is installed at the top, and a handle 16 is installed on the surface of the sliding plate 15. By arranging the support rod 10, the fixed plate 11, the limit plate 12, the limit groove 13, the limit block 14, the sliding plate 15 and the handle 16, a better use effect is achieved. When it is necessary to take and place the workpiece during use, pinch the handle 16 and pull it backwards to make the sliding plate 15 slide backward inside the limit plate 12 through the limit block 14 and the limit groove 13. When the limit block 14 completely slides out of the limit plate 12 through the limit groove 13, the workpiece can be taken and placed, thereby avoiding the existing heat treatment furnace where the workpiece is only passed through the support plate and the support rod. 10 is placed inside the shell 2. When taking and placing the workpiece during use, it is easy for the staff's arm to be burned by the heating ring 4. The support blocks 3 are evenly distributed inside the shell 2, and the heating ring 4 is evenly distributed inside the shell 2, which is more convenient for heating the workpiece and prevents the poor use effect caused by uneven heating of the workpiece during use. The side block B7 rotates on the surface of the side block A5 through the hinge 6, and the cover plate 8 is rotatably connected with the shell 2, which makes it easier for the side block B7 and the cover plate 8 to rotate, and avoids the side block B7 and the cover plate 8 being stuck by the side block A5 or the shell 2 during use. When the block B7 and the cover plate 8 cannot continue to rotate, the support rods 10 are evenly distributed inside the shell 2, and the limit plates 12 are evenly distributed on the top of the fixed plate 11, which is more convenient to limit the sliding direction of the sliding plate 15 and prevent the sliding plate 15 from being offset due to the sliding plate 15 not limiting the sliding direction during use. The limit block 14 slides inside the limit plate 12 through the limit groove 13, and the sliding plate 15 is slidably connected to the limit plate 12, which is more convenient for the limit block 14 to slide and avoids the limit block 14 being stuck by the limit plate 12 during use, resulting in the limit block 14 being unable to continue sliding. Example 2

[0025] See also Figures 1-4, 6. A sealing groove 17 is provided on the surface of the outer shell 2, and a threaded groove 18 is provided on the right side of the outer shell 2. A side plate 19 is installed on the right side of the cover plate 8, a convex block 20 is installed on the right side of the side plate 19, a fixing groove 21 is installed on the right side of the convex block 20, a threaded rod 22 is arranged inside the fixing groove 21, a turning handle 23 is installed on the right side of the threaded rod 22, and a sealing gasket 24 is installed on the back of the cover plate 8, which can better improve its sealing effect. When in use, after the workpiece is placed inside the outer shell 2, the cover plate 8 can be closed. At this time, the sealing gasket 24 slides into the surface of the outer shell 2 through the sealing groove 17, and then hold the turning handle 23 to align the threaded rod 22 with the threaded groove 18 and rotate it, so that the threaded rod 22 is screwed into the inside of the outer shell 2 through the threaded groove 18, and the cover plate 8 is firmly fixed on the surface of the outer shell 2 through the convex block 20 and the side plate 19, thus preventing the sealing performance from decreasing due to the existence of fine gaps between the cover plate 8 and the outer shell 2 after long-term use. The side plate 19 is attached to the right side of the outer shell 2, the threaded rod 22 rotates inside the convex block 20 through the fixing groove 21, the threaded rod 22 rotates on the right side of the outer shell 2 through the threaded groove 18, and the sealing gasket 24 slides on the surface of the outer shell 2 through the sealing groove 17, which is more convenient for the threaded rod 22 to rotate and avoids the situation that the threaded rod 22 cannot continue to rotate due to being stuck by the convex block 20 or the outer shell 2 during use.

[0026] Working principle: When in use, first place the base 1 in the required position so that the base 1 firmly supports the outer shell 2. Then hold the handle 9 and pull it backward, so that the cover plate 8 rotates on the surface of the side block A5 through the side block B7 and the hinge 6. When the side block B7 drives the cover plate 8 to fully open, then hold the pull handle 16 and pull it backward, so that the pull handle 16 drives the sliding plate 15 to slide backward on the top of the fixed plate 11. And at this time, the sliding plate 15 slides on the top of the limiting plate 12 through the limiting block 14 and the limiting groove 13. When the limiting block 14 completely slides out of the inside of the limiting plate 12 through the limiting groove 13, the material can be taken and placed. And during use, the support rod 10 and the fixed plate 11 can firmly support the sliding plate 15 inside the outer shell 2, and the heating coil 4 fixed inside the outer shell 2 through the support block 3 heats the workpiece. When the workpiece is taken and placed, hold the right side of the handle 9 and pull it, so that the cover plate 8 rotates on the surface of the side block A5 through the side block B7 and the hinge 6. When the cover plate 8 is completely attached to the surface of the outer shell 2 and the sealing gasket 24 slides into the inside of the outer shell 2 through the sealing groove 17, then the side plate 19 is attached to the right side of the outer shell 2. Then hold the turning handle 23 to pass the threaded rod 22 through the convex block 20 through the fixing groove 21 and align it with the threaded groove 18, and then rotate it, so that the threaded rod 22 is screwed into the inside of the outer shell 2 through the threaded groove 18, thereby firmly fixing the cover plate 8 on the surface of the outer shell 2 through the side plate 19.

[0027] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
