[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for an experimental heating furnace: an experimental heating furnace includes a heating furnace body 1, a heating inner cavity 2 is provided inside the heating furnace body 1, a furnace cover 3 is provided at the upper end of the heating furnace body 1, a hinge 4 is provided between the heating furnace body 1 and the furnace cover 3, a shelf 5 and a heating tube 7 are provided inside the heating inner cavity 2, a control panel 8 is provided on the outside of the heating furnace body 1, and a lifting assembly 6 is provided between the heating inner cavity 2 and the shelf 5;

[0023] The lifting assembly 6 includes a connecting block 61, a placement groove 62 is provided on the outer side of the heating inner cavity 2, a lifting groove 63 is provided inside the heating furnace body 1, an electric push rod 64 and a guide rod 67 are provided inside the lifting groove 63, a lifting block 65 is provided at the output end of the electric push rod 64, a guide hole 66 is provided in the middle of the lifting block 65, a connecting column 68 is provided at the upper end of the lifting block 65, and a support block 69 is provided at the upper end of the connecting column 68.

[0024] like Figure 1-3 As shown, the heating cavity 2 is a cylindrical structure, the heating furnace body 1 and the furnace cover 3 are connected by a hinge 4, the shelf 5 is a hollow structure, the heating tube 7 and the control panel 8 are electrically connected, the control panel 8 is equipped with control buttons and a display screen on the outside, and the control panel 8 is equipped with a control circuit board and a battery inside, which is conducive to heating the experimental items.

[0025] like Figure 2-4As shown, there are two sets of connecting blocks 61 symmetrically distributed, forming a fixed connection between the connecting blocks 61 and the shelf 5. The number of placement slots 62 is equal to the number of connecting blocks 61, and the placement slots 62 are compatible with the connecting blocks 61. There are two sets of lifting slots 63 symmetrically distributed. The electric push rod 64 is electrically connected to the heating tube 7. There are two sets of electric push rods 64. The lifting block 65 is fixedly connected to the output end of the electric push rod 64. The guide hole 66 penetrates the middle of the lifting block 65, and the number of guide holes 66 is twice the number of electric push rods 64. The guide rod 67 is fixedly connected to the lifting slot 63. The number of guide rods 67 is equal to the number of guide holes 66, and the two are compatible, which facilitates the lifting of the lifting block 65 and ensures the stability of the lifting block 65 during the lifting process.

[0026] like Figure 2-4 As shown, a fixed connection is formed between the connecting column 68 and the lifting block 65. The connecting column 68 is a cylindrical structure, and the number of connecting columns 68 is equal to the number of lifting blocks 65. The upper end of the heating furnace body 1 is provided with a moving hole that matches the connecting column 68, and the moving hole is connected to the lifting groove 63. There are two sets of support blocks 69, which are symmetrically distributed. The support blocks 69 are fixedly connected to the connecting column 68. The support blocks 69 are "U" shaped structures, and the support blocks 69 are matched with the connecting block 61, which facilitates the lifting and lowering of the connecting block 61 and the shelf 5, and further lifts and lowers the experimental items on the shelf 5, making it convenient to retrieve them later without manual handling.

[0027] The working principle of this utility model is as follows: During the use of the heating furnace, the user controls the lifting component 6 through the control panel 8 to lift the shelf 5, places the experimental items to be heated on the upper part of the shelf 5, and then controls the lifting component 6 to lower the shelf 5 along the inside of the heating cavity 2 to close the furnace cover 3. Then, the heating tube 7 is used to heat the experimental items. After heating is completed, the furnace cover 3 is opened, and the lifting component 6 is controlled through the control panel 8 to lift the shelf 5 and the items for easy access by the user.

[0028] It should be noted that, through the setting of the lifting component 6, when the shelf 5 needs to be raised, the output end of the electric push rod 64 controlled by the control panel 8 drives the lifting block 65 and the connecting column 68 to rise. At the same time, the guide hole 66 slides along the outside of the guide rod 67, and the connecting column 68 slides along the inside of the moving hole, further driving the support block 69 to lift the connecting block 61, thereby raising the shelf 5 along the inside of the heating cavity 2 until the movement trajectory of the electric push rod 64 reaches the end point. At this time, the shelf 5 is completely moved out of the inside of the heating cavity 2, thus ensuring that personnel do not need to use tools to reach into the furnace to retrieve experimental items, which is more convenient and less likely to cause burns to personnel's hands.

[0029] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
